This invention pertains to a self-contained vending machine adapted to disperse articles, more particularly video cassettes either as an outright sale or on a rental basis.
~ACKGROUND OF THE INVENTION
Vending machines for dispensing different articles for cash are well known in the art. However inventory control on these machines had to be done manually and there was no in-dication of lost sales other than an "empty" sign indication corresponding to a popular item.
The advent of high speed computer-assisted communi-cation devices brought in machines which were nothing more in reality but electronic extensions of centralized computers.
Through these terminals a customer is able to complete trans-actions such as ordering goods, or obtaining cash from a bank account by using a credit card or other similar identifying means. Such devices can be found in U.S. Patents Nos.
4,134,537, issued January 16, 1974 and 3,662,343, issued May 9, 1972. Devices which dispense articles instead of cash are described by U.S. Patent Nos. 4,120,452 issued October 17, 1978 and 4,300,040 issued November 10, 1981. However because all these devices are mere extensions of a central distribution, they are suitable only for a centralized operation requiring a large investment. Furthermore if the communication link between the terminal and the central computer is interrupted, 3g the terminal becomes useless.
OBJECTS OF THE I~ NTION
An Gbjective of the present invention is to provide a vending machine which can dispense independently articles such as video cassettes while providing inventory control.
A further objective is to provide a device which can be used for dispensing of said article independently on a rental basis.
Another objective is to provide a device which i6 easy to operate by the customer and the owner.
Other objectives and advantages shall be described in conjunction with the following description of the invention SUMM~RY OF THE INV~NTION
In accordance with this invention, an automatic vend-ing machine for video cassettes and similar articles comprises an enclosure: a plurality of holding means, each one adapted to hold one of said articles and to dispense said articles when a release command is received; a selecting means for selec~ing an article to be dispensed and control means connected to said selecting means and adapted to send said releasa command to the holding means associated with the selected article.

A vending machine, in particular for video cassettes, according to this invention comprises an enclosure lO, as illustrated in FIGURE 1, which houses a storage means adapted to selectively dispense cassettes and a control means.
The various elements of the machine are best described in conjunction with its operation. All information from the machine is displayed on an electronic display unit 12. This ~21~439 display unit may be a 5" black and white CRT or any other similar device. In STANDBY mode this CRT displays a menu to the potential customer for selecting either the RENT or RETURN
mode. This selecting may be done by activating one or more keys in a preselected manner. Preferably a single selector keypad 14 i8 provided for use by the customer, having ten or more keys. A membrane-type keypad is particularly useful in this situation because such keypads are dust; water; and tamper-proof.
Once a customer selects the RENT mode he is instructed by the display means 12 to enter a code identifying the cassette he desires to rent. The present device can store either VHS or BETA format cassettes or both. The information on which format the customer needs is part of the code for a particular cassette.
The customer selects the correct code by consulting the master index 15 which is preferably displayed on the front of the vendor machine. Either the whole front of the machine may be used as an index, or only a portion of the front may be dedicated thereto, the rest being used for promotional materials.
After the customer enters the code of the desired cassette, a check is performed to see whether ~he desired cassette is in stock. If it is not then the customer is invited to make another choice. If the cassette is available the customer is instructed to insert a credit card or other 1~8~39 means of charging the customer for rendered goods and/or services into a slot 16. Behind the slot is a magnetic stripe card reader 16 of the type well-known in the art which reads the information magnetically stored on such cards as shown in FIGURE 7. The information gathered by the magnetic stripe reader is sent to a central processing unit 20. This unit is also connected to a driver 22 which acts as an interface between the central processing unit 20 and the digital display L~ unit 12. In fac~, the central processing unit ~i~ as a clearing house for all the information changes within the vendor. Naturally it also receives the information entered by keypad 14 by the customer, including the code number for the desired cassette and determines whether the desired cassette is in fact available. In all its functions, the central pro-cessing unit makes use of a memory unit 24 in which all the required information is stored in a non-volative fashion. Pre-ferably the me~ory unit comprises a magnetic disk and a compatible disk drive or a magnetic bubble memory.
Before the transaction continues, a check is performed on whether the credit card is acceptable. This is done by con-tacting a central information bank (not shown) where such datais electronically available. The contact can be made either through a modem 26 which transmits the identification number of the credit card, and if required, the amount of the trans-action, and receives a confirming message from the central line via a standard telephone company communication line 30. Alter-~.,'~1 13~39 natively a dedicated line 32 may be used through an interface unit 34, such as for example an RS 232C interface. It should be emphasized that except for this credit card checking feature, all other functions are performed internally within the vendor machine. Furthermore it is possible to operate the unit exclusively internally either by using a specialized credit care which could be used only for tape rental, or by storing in the memory a list of all the numbers of all the unacceptable credit cards, and by frequently updating the list. After the credit card is verified the central processing unit Zo activates an appropriate mechanical release mechanism such as a solenoid 36 to dispense the appropriate cassette.
This latter function is described in more detail further on in this disclosure.
The customer also receives a printout from printer 38 which identifies the location of the vendor machine, the tape dispensed and the terms of the rental, including the fees in-volved and the return dates. If the tape is not returned within a preset period of time, it is assumed that the customer wants to keep the tape and will be billed accordingly.
The video cassettes used in the vendor are preferably encoded by using an adhesive strip with a unique bar code.
Once an identifying strip is attached to a given cassette, the vendor machine keeps track of a given cassette through its code.
If a customer selects the RETURN mode for the machine, he is instructed to insert his credit card in slot 16 and to put the tape into a return slot 40. A bar code sensor 42 (see FIGURE 7) is used to sense the identifying code of the cassette. The code is decoded by a bar code reader 44 and sent to the central processing unit 20. The processing unit checks whether there is open transaction related to the cassette. If there is no record of such transaction the cassette is returned to the customer, and the customer is informed of this event.
If there is an open transaction, ie. the cassette has been rented from the subject vendor, the central processing unit calculates the rental charge, and issues an appropriate receipt through printer 38.
At preselected time intervals the vendor machine is put into a SERVICE mode by selecting the RETURN mode and in-secting a specially-coded service sard into card reader 16. In this mode the service person can accomplish the functions:
related to the day-to-day operation of the vendor related to net sales, inventory control, unfulfilled requests, open trans-actions, and net income. The service person can also add and delete cassettes from the active inventory. Advantageously, for this func~ion he can use the bar code sensor 40 and reader 42 to identify new or removed cassettes. Information requested by the service person is displayed by display unit 12, and a permanent record is made by printer 38.
A typical decision chart for implementing the RENT, and RETURN modes is shown on FIGURE 8. The decision chart for implementing the SERVICE mode is shown on FIGURE 9. The cen-~Z~8 ~39 tral processor unit 20 is programmed to perform the above-described functions in the manner illustrated in FIGURES 8 and 9. Of course the same functions could be performed by vacious other steps and decision charts well-known in the art.

The physical storage of the video cassettes may be done in a number of different ways. Preferably a rack ~6 as shown in FIGU~E 2 is provided inside enclosure lO. The rack comprises a plurality of ~iers each tier being adapted to hold several cassettes in a row. The rack may be made out of metal rods, or similar light materials. Each tier 48 is at an angle, as shown most clearly in FIGU~E 3 so that a cassette 50 resting thereon can slip off the tier and down into delivery chute 52.
The delivery chute can be reached through a swin~ing access door 54. The swinging door is hinged at the top at 56 and is preferably made of a plastic transparent material so that the customer can see that the cassette 50 has been delivered, as well as for aesthetic purposes.
The mechanism for releasing the cassette on command is illustrated in FIGURES 3, 4, and 5. It comprises a rod or similar rigid member 58 dispersed longitudinally underneath a member 60 of the rack 46. The cassette 50 is resting on the member 60. The rod is affixed rotatably to member 60 at points 62 and 6~ so that it can rotate around its own axis. The rod is terminated with a lower arm 66 and an upper arm 68 each arm being bent at approximately 90 with respect to the rod. The lower arm 66 normally extends beyond member 60 generally up-wards from rod 58 so that it forms the lowest rest point for the cassette 50. Thus, if the rod is rotated so that arm 66 moves away from the cassette, the cassette 50 is free to slip off from the rack 60.
Also on member 60, preferably above cassettee 50 is a solenoid 36, which is one of the central processor unit-8 ~39 activated solenoids shown in FIGURE 7. The solenoid is electrically connected to the central processor unit and has a plunger 70 which moves axially to the left in FIGURE 4 as the solenoid 36 i8 activated. The plunger is pivotally connected 5to upper arm 68 of rod 58. Therefore when the solenoid 36 is activated, plunger 70 moves right in the direction shown by the arrow in FIGURE 5, the rod 58 rotates clockwise, and the lower arm 66 moves downward accordingly releasing the cassette 50 associated with the solenoid. Thus the release of the cassette 10into the delivery chute 52 on command from the central pro-cessinq unit 20 is effectuated.
As shown in FIGURE 6, the return mechanism 40 (FIGURE
l) comprises a tray 70 pivotally mounted at its lower portion 72 to the front panel 74 of the vendor so that when it is 15closed, the front face 76 of the tray is flus-h with the front panel 74. At the top the front face 78 ends with fingergrip-type handle 78 which can be used to turn or pivot tray 70 in and out. Tray 70 is adapted to hold cassette 50 preferably on ~ its edge as shown in FIGURE 6. Instructions for inserting the 20cassette into the tray can be mounted on the insid~ ~,urface 80 of the front face 76 or adjacent to it.
As previously described each cassette 50 is provided with an identifying label 82 which is electrically or optically encoded to provide identifying information abou~ the respective 25cassette. After the cassette is inserted into the tray, the tray is pivoted back into the main body of the vendor. As the ~8~
tray is being pivoted, the label of the cassette passes by a code sensor such as a bar code sensor 42. As the tray reaches the flush position, the identifying code of the cassette is sent to the central processor 20. If the cassette matches an open transaction the central processor operates a release mechanism 84 which allows a rear portion 86 to swing back and release the cassette into a storage bin 88.
During servicing the operator gains access to the storage bin and removes the returned tapes. He may take them away or he may reload them together with new tapes into the vendor du~ing the vendor machine servicing routine. For example, if during seIvicing (see flow chart on FIGURES 9 and 10), the operator decides at decision block 4 to add new tapes to the machine's inventory he will be instructed to insert the first new tape into the return slot 40. The code of the tape is then read by code bar sensor 42 and reader 44 and this is transmitted to the central processor 20. The central pro-cessor, which keeps track of all the empty cassette loca~ions, enters the identification of the cassette, assigns an empty location to the cassette and instructs the operator to remove the tape from the the return slot and placed at the designated location. Now the operator is free to insert another new tape.
In summary, the vending machine has three modes of operations: RENT, RETURN and SERVICE. A potential customer initially has the option of selecting the RENT or RETURN
modes. In the RENT mode, on request from the central pro-~2~3439 cessor, the customer enters the identification nu~ber of the desired tape and its format (BETA or VHS). The processor checks its inventory ~o determine whether the desired tape is available. If the tape is available, the customer is requested to provide a credit card. After the credit card is validated a hard copy of the transaction is pLovided to the customer, and the appropriate solenoid is activated to cause the cassette to drop into the delivery chute.
If the RETURN mode is selected, the customer is requested to insert his credit card and the cassette into the respective slots. If the cassette is recognized as an open transaction ie. a cassette involved in a rental, ~he cassette is dropped into a storage bin, the rental charge is calculated, and a hard copy of the finalized transaction is provided to the customer. If the cassette is not recognized it is returned to the customer.
The SERVICE mode is initialiæed by an operator by first selecting the RETURN mode and then by inserting a special service card into the card reader. Once the special service card is recognized a special service menu is displayed on the display screen and the service operations involving sales in-formation, inventory control, rate changes, replacement of cassettes may be performed.
The subject vending machine was described in con-junction with the renting and/or sale of prerecorded videocassettes. However its obvious that it may be used for the 8 ~39 distribution of various other boxed articles with little or no modifications such as video games, computer software, paper-backs and blank tapes. FuLthermore numerous modifications could be made in the subject device by one skilled in the art without depar~ing from the scope of the invention as defined in the appended claims.
