Description

The present invention relates to a hand-held input keyboard for a personal computer that is convenient for wireless operation. In particular, the keyboard is small and light and can be easily operated with one hand or both hands. -It is related with the input keyboard which can perform cursor operation and also has a scroll function.

The keyboard is the basic and most important input device of a personal computer. By operating the keyboard, commands are sent to the PC system to perform the desired work. At present, the standard PC of the computer is used together with the keyboard to move the cursor and click with the mouse and the flat point that has the same function as the mouse, and to select the inactive window and scroll the browser. Input device.

People who frequently use computers at home want to operate their computers in a relaxed state, sitting on a sofa or lying on a futon, just like watching TV. On the other hand, you can purchase and enjoy a large-screen monitor that looks good on the eyes. In order to achieve such ideals, wireless keyboards and mice are now available for desktop computers, and it is possible to operate remotely from a computer desk by remote operation. However, the current wireless keyboard and mouse are too large to be moved with one hand, and it is still too big to make a wireless keyboard with the size of a laptop keyboard. On the other hand, if the key on the keyboard is made as small as the key on the mobile phone, it is difficult to operate the personal computer more complicated than the mobile phone. Therefore, it is still far from a light and small personal computer input device that can be easily moved with one hand like a general remote controller and that is easy to operate keys.

Therefore, the present invention is small and light and can be easily operated by holding it with one hand or both hands. In addition, the key input and cursor operation can be performed wirelessly from a position away from the main body of the personal computer, and the scroll function is also provided. The purpose is to provide a handheld input keyboard for personal computers that is convenient for wireless operation.

The handheld input keyboard for a personal computer convenient for wireless operation according to the present invention has a built-in power supply circuit. A wireless signal emitting device for transmitting wireless signals through the keyboard case is built in the front edge facing the PC main body, and both sides of the input keyboard are longer than the middle stage of the input keyboard and downward. While forming an arch shape and drawing a curve toward the front edge, the width gradually decreases and the tip forms a protruding hand-held portion. Also, the keyboard that is operated with the thumbs of both hands is provided with keys to which the most basic functions are assigned, and by first pressing the key definition switching key to switch the contents input with the composite key, or By combining multiple keys with different key control functions, the smallest and most basic number of keys covers the numbers, symbols, or character codes that can be entered by the key, and the size of the key The entire keyboard can be made smaller and lighter without being made as small as a button of a mobile phone. A flat point for operating the PC cursor with the fingertips without turning the keyboard upside down is provided at the place where the index finger or middle finger of both hands touches on the back side of the keyboard, eliminating the need for mouse operation. The flat point can be operated by one-click control or multiple-click control. A scroll function area similar to that of a mouse of a personal computer is provided at a position convenient for operation with a finger at a flat point.

The power supply circuit is composed of a rechargeable battery and a charge control circuit. The charge control circuit is provided with a USB connector for charging by connecting to the USB port of the PC main body, and the USB connector is exposed on the surface of the input keyboard. At the same time, the battery is connected to the power supply of the USB port of the personal computer main body to charge the rechargeable battery.

In the center of the outer side of the hand-held portion, an arc-shaped support groove is provided, which is convenient for grasping with the index finger and middle finger of both hands and extending the index finger and middle finger of both hands to a flat point.

A thin film is provided on all the key surfaces of the key, and the surface layer of the key surface is an electronic translucent film.When a specific key is pressed, all the key surfaces are lit, and the character code or code on the key surface is When you work in a dark place, you can see the key face clearly and press the key accurately.
