Abstract: PURPOSE:To prevent such a state that a thermal head driving power supply is continuously set to an ON or OFF state by static electricity or noise, by controlling ON/OFF of the thermal head driving power supply by the signal obtained from a printing start switch. CONSTITUTION:When a printing start signal 6 is inputted to a head power supply control part 7, a printing signal 5 is inputted to a driver control part 8 and a power supply for a head 10 is applied to the head 10 to perform printing. However, when the printing start signal 6 is not supplied to the head power supply control part 7, even if the printing signal 5 is inputted to the driver control part 8, the power supply for the head is not applied and printing is not performed. Therefore, even when the signal corresponding to an erroneous printing signal is inputted to the driver control part 8 by static electricity or noise, unless the printing start signal 6 is inputted to the head power supply control part 7, the head power supply is not applied to the head 10. That is, the head 10 is protected from static electricity or noise.

Title: Signal transmission circuit
Inventor: TERADA SATORU
IPC: H04B10/60
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To surely perform signal transmission even when the current transmission efficiency of a photoelectric converting circuit is lowered. SOLUTION: A photocoupler PC2 for current detection is provided while having the equal current transmission efficiency with a photocoupler PC1 for signal transmission when performing the signal transmission through the photocoupler PC1 for signal transmission, and light emitting parts Pd1 and Pd2 of these photocouplers PC1 and PC2 are serially connected. Since a detection current Im on the side of a light receiving part Pt2 of the photocoupler PC2 for current detection can be regarded equal with a secondary current I2 on the side of a light receiving part Pt1 of the photocoupler PC1 for signal transmission, the state of the secondary current I2 can be estimated from the detection current Im.  Therefore, when the detection current Im is lower than a preset reference value, by reducing the resistance value of a primary current control part 20, a primary current I1 is increased so that the secondary current I2 is increased as well according to this reduction and an output signal VOUT becomes a prescribed voltage value. Thus, even when current transmission efficiency is lowered, the output signal VOUT of the prescribed value can be surely transmitted.

Filed: 1984-02-28
Abstract: PURPOSE:To improve the power consumption efficiency by shifting sequentially a shift register when a parallel signal of plural bits is set to the shift register and outputting selectively sequentially series signals outputted from the shift register. CONSTITUTION:Signals D1-D8 are set simultaneously to the shift register 1 by a set pulse S, signals D9-D16 are set to a shift register 2 similarly and signals D17-D24 are set to a shift register 3. The signals D1-D24 in 24-bit are set to the shift registers 1-3 while being split as parallel data in this way. A pulse P of a period T is generated from a pulse generating section 5, the pulse P is fed to the shift register 1 via a contact of a switch section 6 and fed to an octal counter 7. Since the shift register 1 is shifted sequentially by the pulse P, the signals D1-Dn are extracted serially from the output terminal A and fed to an input terminal (a) of a matrix circuit 4. Thus, the signals D1-D8 are outputted serially from the output terminal Z of the matrix circuit 4 and fed to a display section 8.
