技术领域technical field

本发明关于携带式计算机，特别关于一种具有一容置开槽内活动地容纳有一键盘装置的携带式计算机。The present invention relates to a portable computer, in particular to a portable computer with a keyboard device movably accommodated in an accommodating slot.

背景技术Background technique

由于人们在日常生活常使用的移动式电子产品，例如：笔记本电脑(NoteBook)、移动电话(Mobile phone)、MP3播放器(MP3 Player)、游戏机(PSP)、数字相机(Digital Camera)、车用导航系统(GPS Guide)及随身数字助理(Personal Digital Assistant)的机会愈来愈多，各大电子厂商都不断地推陈出新，都朝向多功能的需求进行研发，以满足许多使用者的需求，尤其是着重于文书编辑、多媒体播放、无线上网等功能，已渐渐纳入移动式电子产品中，与移动式电子产品融合为一，不需再购买其它相关的装置，才能同时拥有这些功能。因此，此种趋势确实符合了许多使用者的需求，造成使用者的青睐。故，未来的移动式电子产品能否提供更方便、更有效的结构，俨然已成为评价各国高科技产品的创新技术，是否领先他国的重要指针之一。Due to the mobile electronic products that people often use in daily life, such as: notebook computer (NoteBook), mobile phone (Mobile phone), MP3 player (MP3 Player), game console (PSP), digital camera (Digital Camera), car There are more and more opportunities to use GPS Guide and Personal Digital Assistant. Major electronics manufacturers are constantly innovating, and they are all developing towards multi-functional requirements to meet the needs of many users, especially It focuses on functions such as document editing, multimedia playback, and wireless Internet access. It has gradually been incorporated into mobile electronic products and integrated with mobile electronic products. It is not necessary to purchase other related devices to have these functions at the same time. Therefore, this trend does meet the needs of many users, causing users to favor it. Therefore, whether future mobile electronic products can provide a more convenient and effective structure has become one of the important indicators to evaluate whether the innovative technology of high-tech products in various countries is ahead of other countries.

目前各大电子厂商有鉴于移动式电子产品均以轻薄短小且携带方便的研发方向为重点，而不断地减少产品本身的体积及重量，便开发出一种介于随身数字助理和笔记本电脑之间的超迷你移动计算机(Ultra-mobile PC，UMPC)，此种超迷你移动计算机不需外部的输入装置(如键盘、鼠标及手写板等)，将所有移动式电子产品应有功能的电路设备均整合至此种超迷你移动计算机内，如而省略鼠标及键盘，而改以触碰式屏幕(Touch Panel)作为输入装置，以提供光标移动、文字书写及显示画面的功能，以试图缩减超迷你移动计算机的重量。然而，使用者在还未习惯以触碰式屏幕输入文字进行编辑时，各大电子厂商均选择性地提供一键盘装置，或与触碰式屏幕相设于一起，使得使用者仍可于超迷你移动计算机的使用下持续操作键盘装置。At present, major electronics manufacturers have developed a mobile electronic product that is between a portable digital assistant and a notebook computer in view of the fact that mobile electronic products are all focused on the research and development direction of thin, light, small and portable, and continue to reduce the size and weight of the product itself. The ultra-mini mobile computer (Ultra-mobile PC, UMPC), this kind of ultra-mini mobile computer does not need external input devices (such as keyboard, mouse and tablet, etc.), and all the circuit equipment with functions of mobile electronic products Integrate into this ultra-miniature mobile computer, such as omitting the mouse and keyboard, and instead using a touch screen (Touch Panel) as an input device to provide cursor movement, text writing and display screen functions, in an attempt to reduce the size of the ultra-miniature mobile computer. The weight of the computer. However, when the user is not used to inputting text on the touch screen for editing, major electronic manufacturers selectively provide a keyboard device, or set it together with the touch screen, so that the user can still use the touch screen to enter the text. The keyboard device is continuously operated under the use of the mini mobile computer.

然而，若超迷你移动计算机选配有一键盘装置，但键盘装置却无法其方便地与超迷你移动计算机一起携带，将失去超迷你移动计算机原有轻便携带的特性，但若将键盘装置与超迷你移动计算机设于一起，由于超迷你移动计算机较键盘装置较重，却会造成键盘装置无法支撑超迷你移动计算机，使得超迷你移动计算机的重心不稳而带动键盘装置翻倒。故，若能开发出一种超迷你移动计算机，既可提供使用者方便携带的键盘，又可支撑触碰式屏幕，不至被触碰式屏幕向后翻倒，实乃将是业界的一大进步，也是消费者的一大福音。However, if the ultra-mini mobile computer is equipped with a keyboard device, but the keyboard device cannot be easily carried with the ultra-mini mobile computer, the original light and portable characteristics of the ultra-mini mobile computer will be lost, but if the keyboard device is combined with the ultra-mini mobile computer. The mobile computers are arranged together, because the ultra-mini mobile computer is heavier than the keyboard device, but the keyboard device cannot support the ultra-mini mobile computer, making the center of gravity of the ultra-mini mobile computer unstable and causing the keyboard device to fall over. Therefore, if a kind of ultra-mini mobile computer can be developed, which can provide the user with a conveniently portable keyboard and support the touch screen so that it will not be overturned by the touch screen, it will be a breakthrough in the industry. Great progress is also a great boon for consumers.
