Title: Resistor pressure sensitive type tablet
Inventor: YOSHIKAWA OSAMU
IPC: G06F3/045
Filed: 1990-08-22
Abstract: PURPOSE:To prevent insulating characteristics from being deteriorated like a pin hole in an insulating layer and to eliminate a defective position in the rise part of an electrode by forming the insulating print of an undercoat by many layer, forming the undercoat consisting of the many layers as a step-like part on its boundary part with a resistor layer and forming an electrode on the step-like part. CONSTITUTION:The resistor layer 9 with fixed thickness is formed on an insulating base 8, the non-detection part of the layer 9 is coated with the insulating layer 18 of the undercoat by many layers with thickness capable of preventing the generation of a pin hole to form layers for X and Y axes. The layer 18 consisting of many layers is formed as the step-like part 20 on both the end parts of the boundary between the layer 18 and the exposed resistor layer 9 and the electrode 10 is formed on the step-like part 20 so as to cover the end parts of the layer 18. Consequently, a tablet resolving both problems, i.e. unsufficient formation of the electrode and the deterioration of insulating property due to a pin hole can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a driving device for the original read part of a copying machine capable of detecting a control unfeasible state and stopping processing for a motor without the runaway of a scanner when an encoder signal being the control reference of the motor is omitted. SOLUTION: When a servo motor 21 is stopped (motor driving signal is OFF), the reset IC of a watchdog timer circuit 25 according to a clock generated by a clock frequency divider circuit 26 is cleared. When the motor 21 is operated (motor driving signal is ON), the reset IC of the timer circuit 25 is cleared according to an input signal from an encoder 22. In the case the encoder signal is not inputted, a motor stop signal is outputted from the reset IC and the motor driving circuit 23 of the motor 21 is turned off so as to stop the motor 21. Furthermore, the driving shaft 38 of a scanner carriage is braked by an electromagnetic clutch 28 for braking according to the motor stop signal of the reset IC, whereby the scanner carriage moving inertially is surely stopped.

Abstract: PURPOSE:To reduce a rush current of the time when a power source is turned on, by controlling an FET between an inverter of a timing circuit and the ground by an FET coupled with a power source by the same conductive type. CONSTITUTION:..The gate potential of P type FETs Q2-Q5 for connecting an input of inverters IV2, IV4...IV8 and the ground, in CMOS inverters IV1-IV5 for generating a preamplifier timing signal phiPa and an inversion phiPa, when a power source is turned on is turned on by L of a floating state by a parasitic input capacity. Accordingly, the input of the inverters IV2, IV4...IV8 becomes a ground potential and the output becomes H, and as for an input level of the invertors IV1-IV8, a period in which it becomes an intermediate level is shortened. When the power supply voltage exceeds a threshold level, a P type FETQ1 whose gate is connected to the ground is turned on, the gate is controlled and the FETs Q2-Q5 are turned off. According to such constitution as a period in which an input of the inverter becomes an intermediate level, when the power source is turned on, a through-current is suppressed, and a rush current of the time when the power source is turned on is reduced.
