題があった。In such a panel keyboard, the switches consisting of corresponding contact patterns have different operating pressures or operating pressures between the switches to be selected and the switches not to be selected so that a specific one of them can be selected and operated. It is preferable that the keyboards be different from each other, but in the case of panel keyboards that are the same size, that is, the size of the contact patterns are the same, in the case of conventional products, both The operating pressure or operating pressure of the switches is also the same, and there is a problem in that the above-mentioned demands cannot be met.

The switch operation gap /3, the contact pattern /lI formed on the switch sheet described later, and the bonding layer /4 are constructed in the same manner as in the conventional example described above, but the switch sheet formed on the flexible flat plate )/7, the thickness of each part where the contacts /l are formed is different from each other, for example, each forming part A of the two contact patterns /2, /, 2 shown in the figure.
and B, the thickness t2 of one part B is made larger than the thickness te of part B to form the increased thickness part/7A. As described above, as a method for partially thickening the switch sheet), for example, a pressure-sensitive flexible film may be attached to the corresponding part B of the switch sheet having a thickness t□ shown by the dashed line in the figure. A method of adhesion using an adhesive or a rubber adhesive may be mentioned.

容易になる。In the panel keyboard configured in this manner, the operating pressure or operating pressure is greater at the portion B than at the portion A, since the contact pattern 12 and the contact pattern 11 are brought into contact with each other. Therefore, the switch selection operation can be easily specified by the difference in operating pressure or operating pressure.

／？。FIG. 3 shows another embodiment of the present invention, in which the present invention is applied to a panel keyboard of the type in which the switch operation gap is formed in a dome shape so as to give a click feeling to the fingertips when operating the switch. . That is, this panel keyboard has the required number of contact patterns 1 on each of the four parts as shown in the figure.
On a flexible base member 20 having a contact pattern 19 formed thereon, a switch sheet 22 having contact patterns 1 and 2 corresponding to the contact pattern 19 is placed via an insulating spacer 23 and a bonding layer 2. , a dome-shaped switch operation gap 2j is formed. And in particular, the base member -〇Fi,
Each part where the contact point 19 is formed, that is, the thickness outside the recessed part is formed to be different from each other, for example, the two contact patterns shown in FIG. .

もつ。According to the present invention, the thickness of the contact pattern forming portions of at least one of the pace member or the switch sheet of the panel keyboard is formed to be different from each other, so that the operating pressure or the operation pressure of each contact pattern forming portion is made different from each other. Since the pressures are different from each other and the switch selection operation can be easily specified, it has practical effects such as simplifying the configuration.
