Title: Input device
Inventor: YOSHIDA MOTOHIKO
IPC: G06F3/043
Filed: 1985-01-24
Abstract: PURPOSE:To obtain an inexpensive device for allowing the counting operation of a counter by a pulse oscillator having low oscillation frequency and to detect highly accurately coordinates by forming a delay layer for delaying the transmission time of a vibration wave generated by keying on a substrate. CONSTITUTION:When an optional point A in a keying range is depressed by a keying pen, a vibration wave is generated on the substrate 4, transmitted and reached to pickup parts 1-3. Respective transmission times are counted by clock counters 10-12 counting up the pulses of the pulse oscillator 13 and respective time differences are found out to detect the coordinate value of the point A. The substrate 4 is formed by an iron plate and the delay layer 14 consisting of zinc to delay the transmission time of the oscillation wave is plated on the substrate 4. Consequently, the transmission speed of the oscillation wave is about 1,200m/s and the time required for the arrival of the wave at the pickup part separated from the substrate 4 by 300m is 250mus. Therefore, the frequency required for 15,000 counts of the counter is 60MHz, so that the oscillation frequency of the oscillator 13 may be extremely reduced as compared with the substrate consisting of only the iron plate.

Filed: 1982-01-29
Abstract: PURPOSE:To decrease the number of transmission/reception lines, by adding a Zener diode to each station and transmitting signals among plural stations by means of a double-core twist cable. CONSTITUTION:Transistors TRT1 and TRT2 serving as elements for transmission are turned off while both stations A and B are not performing transmission. In such a case, a line 1' is cut off and transmits no current, and therefore light emitting diodes 21a and 22a in receiving photocouplers 21 and 22 emit to light. Thus phototransistors 21b and 22b corresponding to the diodes 21a and 22a are turned off. When the station A turns on the TRT1 with a transmitting signal (a), the line 1' conducts. Then a current flows in order of a current limiting resistance R1, the TRT1 the diode 21a in the coupler 21, the line 1', a current limiter R2 within the station B, a Zener diode 24 and the diode 22a in the coupler 22. When the current flows to the diode 22a at the station B, the diode 22a emits light to turn on the phototransistor 22b.
