Abstract

(57) [Abstract] [Purpose] As a pointing device for a computer, using existing writing instruments (ballpoint pens, pencils, etc.), data that a computer can handle, such as letters, figures, and pictures, can be used as if writing letters, figures, and pictures. Convert and input to computer. [Structure] Ultrasonic transmitters 1, 3 and infrared transmitters 2, 4, trigger switches 15, 16 are incorporated in a pen-shaped casing. Ultrasonic receiver 5,8,
7 and 10, infrared receivers 6 and 9, a reference transmitter 12, counters 11 and 13, and a controller 14 are incorporated.

Description

[Detailed Description of the Invention] This invention mainly deals with inconveniences of existing input / output devices of a computer (hereinafter referred to as a computer), which is a main touchpad, a trackball, a mouse, mainly by ultrasonic waves and infrared rays. The computer input of figures, characters, and pictures with a mouse or trackball, which I was not good at until now, can be easily input to a computer as if using a writing instrument by using this echo pen. . With the touchpad, you can input pictures and characters as if you were using a writing instrument, but the device itself is large and inconvenient to carry, and it is expensive to save space.However, this device is compact, low-priced, and convenient to carry. Does not take up space. Also, the receiving device can be incorporated in the computer.

 The present invention will be described with reference to the drawings. Now, the transmitters 1, 2, 3, 4, 15, 16 and the receivers 5, 6, 7, 8, 9, 10, 11, 12, of FIG. When the components 13 and 14 are at an arbitrary distance, ultrasonic waves are emitted from 3 and infrared signals are emitted from 4 at the same time. You can see that it was fired at the same time. The light reaches the instant 6 and 24 is its waveform. With this signal, the counters 11 and 13 are reset and start counting the signal of the reference clock waveform 27 made of 12. The ultrasonic waves reach 5 and 7 depending on the distance between 3 and 5 and 3 and 7 respectively. The received waveforms at that time are 25 and 26, and the counters 11 and 13 stop counting at this signal. Let 28 and 29 represent the time from when the counter starts counting after the 24 signal arrives until it stops counting. The value obtained by this operation is directly output to the computer. In addition, based on this value, it is configured by 14 sub-computers and software and arithmetic calculation is performed to output the distance between 3 and 5 and 3 and 7 to the computer, or the position of 3, 5, 7 in the coordinate system. When you want to handle, 5 and 7 are placed on the horizontal coordinate (hereinafter referred to as the X axis), and when the axis intersects 5 or 7 at right angles to the X axis (hereinafter referred to as the Y axis), the position of 3 is the X axis and the Y axis. It can be output to the computer as a value. In addition, the infrared ray signal can also be modulated to handle the signals of the trigger switches 15 and 16. In the present invention, as shown in FIG. 2, the transmitters 1, 2, 3, 4 and the trigger switches 15, 16 are installed in a pencil shape, and an infrared signal is transmitted from 17 and the first pen tip. It is important to be able to emit ultrasonic waves from a hole made nearby. Further, this can be used as the ballpoint pen 19 by removing the cap 20, and the trigger switch 16 can be pushed by pushing the pen tip. With the above configuration, the device can comfortably input to the computer.
