Description

Computer handwriting input wireless transmission device

technical field

The utility model belongs to computer hardware, in particular to a computer handwriting input wireless transmission device.

Background technique

Computers have been widely used in people's daily life and work, playing an important role. As a computer input device, the handwriting tablet has also been greatly developed, especially for people who do not like to use a keyboard or are not used to using Chinese input methods. In addition, the handwriting tablet can also be used for drawing. The tablet generally uses a special pen or finger to write text or draw in a specific area. The tablet records the trajectory of the pen or finger through various methods, and then recognizes and processes it through a computer. Existing handwriting pads usually set a handwriting area of a specific size on the device. This area uses a touch panel material. The user touches the touch panel with a finger or a pen, and the touch panel material transmits the written track. The computer converts it into coordinate information and displays it on the screen. This kind of handwriting tablet cannot display the written handwriting on the writing tablet at the same time as real writing on paper. The writer must keep a close eye on the screen and cannot achieve hand-eye integration, which has caused many troubles.

Contents of the invention

The utility model aims at overcoming the deficiency of the prior art, and provides a computer handwriting input wireless transmission device.

The wireless transmission device for computer handwriting input of the utility model is composed of a writing pen, a writing board and a touch panel. The touch panel of the device is provided with a detachable writing board and function keys, and the upper part of the device is provided with a connection display lamp and The signal transmitter is provided with an induction coil at the upper end of the tip of the writing pen.

As a further improvement of the utility model, the touch panel is an electromagnetic induction panel.

As a further improvement of the utility model, the writing board is a magnetic handwriting whiteboard.

As a further improvement of the utility model, a USB interface is provided on the upper part of the device.

The wireless transmission device for computer handwriting input of the utility model has a reasonable structural design, is convenient to use, and is convenient for writing and changing. It uses a cheap magnetic handwriting whiteboard as a display device, which can not only display the writing track, but also does not need to be separately equipped with an expensive LCD screen or Other display devices greatly reduce the cost and expand the scope of use.

Description of drawings

Fig. 1 is a schematic structural diagram of a computer handwriting input wireless transmission device.

Detailed ways

As shown in Figure 1, the computer handwriting input wireless transmission device of the present utility model is made of writing pen 1, writing board 2 and touch panel 3, and the touch panel 3 of device is provided with detachable writing board 2 and function Button 4, the upper part of the device is provided with a connection indicator light 5 and a signal transmitter 6, the signal transmitter 6 is wirelessly connected to the computer host, when the connection is successful, the indicator light 5 will be on. An induction coil 7 is arranged at the upper end of the nib of the writing pen 1 . The touch panel 3 is an electromagnetic induction panel. The writing board 2 is a magnetic handwriting whiteboard. The upper part of the device is provided with a USB interface 8. When the display lamp 5 is not bright, it means that the signal transmitter 6 is unsuccessfully connected with the host computer. At this time, the USB interface 8 can be enabled, and the input device is connected to the computer with a traditional data cable.

The handwriting board 2 adopts a magnetic handwriting whiteboard, which has the same structure as the existing magnetic whiteboard, and is equipped with a writing pen 1 and an eraser. The touch panel 3 is an electromagnetic induction panel. After the touch panel 3 is energized, an electromagnetic field is formed within a certain space range. When the writing pen 1 with the induction coil 7 passes through the magnetic field area, the pen tip generates a corresponding magnetic field, and the stylus 1 does not touch The touchpad 3, the touchpad 3 can also sense the position of the pen tip with the help of a magnetic field. When the pen tip touches the handwriting pad 2, the touchpad 3 automatically performs software recognition to achieve the writing effect.
