Title: Piezoelectric printing head drive circuit
Inventor: HORI SHINICHI
IPC: B41J2/30
Filed: 1985-11-23
Abstract: PURPOSE:To prevent a circuit or a unit from being damaged by a large amount of electric current when a shortcircuit mode failure has occurred by providing an overcurrent detection circuit with a latching circuit between a one-way electrode of a piezoelectric element and a ground and operating a main switch circuit for a drive power supply on an output signal from the overcurrent detec tion circuit. CONSTITUTION:When a piezoelectric element 5 has developed a short-circuit mode failure, a switch circuit 1 is closed, applying a voltage E, causing an overcurrent to generate and thereby allowing a voltage in a reversing input terminal of a voltage comparator 95 to exceed a reference voltage of a reference voltage input terminal. In this case, an output terminal is turned OFF, reaching a low level 'L'. Consequently, an enable terminal G of a latching circuit 97 goes to a high level 'H' through an inverter circuit 96, resulting in the latching of high level data 'H' at a data terminal D for the latching circuit 97 and subsequent setting of an output terminal Q to a high level 'H'. This brings a main switch circuit 81 to 'open' state shutting off a drive power supply 8 and a load circuit for protection.

Title: Overcurrent protection device
Inventor: YOKOI NOBORU
IPC: H01H85/02
Filed: 1992-10-02
Abstract: PURPOSE:To ensure an easy assembly work, and enable a circuit to be kept in off state, regardless of the deposition strength of a contact, by providing a pair of terminal blocks, a bimetal sheet, a spring terminal, a heater terminal block, a heater and a metal having a low fusion point. CONSTITUTION:When load current flows through a circuit comprising a spring terminal 23, a heater 26, a heater terminal block 24, a metal sheet 27 having a low fusion point, a pair of terminal blocks 15, a bimetal sheet 18 and another pair of terminal blocks 14, the heater 26 and bimetal sheet 18 generate heat by themselves in proportion to an amount of current. Then, upon an increase in current due to the occurrence of overcurrent state, and a rise in the temperature of the sheet 18 up to or above a preset value, the sheet 18 performs reverse operation to cut off the circuit. When a load is cooled and the temperature of the sheet 18 drops to or below a preset value, the sheet 18 is reversed and reset to again close the circuit. In this case, if overcurrent state continues, the sheet 18 is repeatedly reversed and reset, resulting in a fatigue break and a subsequent contact deposition. As a result, power is continuously supplied and the heat of the heater 26 is transferred from the terminal block 24 to the metal sheet 27. Then, the metal 27 is fused to release connection between the blocks 24 and 25, thereby enabling the circuit to be turned off, regardless of contact deposition strength.

CONSTITUTION:According to a command for starting the sending of a decalcomania paper, a driving motor 23A is driven to move a support bracket 15 in a width direction of the decalcomania paper, and a supply unit 10 is moved until it corresponds with any one of paper width sensors 19, 20, 21 correspondent to the width size detection of the decalcomania paper on the side of a supply cassette, and is stopped and held to set the positions of a supply roller 10A1 and a separation roller 10B1 to the central position in the width direction for each decalcomania paper. A supply driving motor 22 is driven to execute the separate sending of the decalcomania paper through the supply roller 10A1, and the separation roller 10B1. Abnormal supply due to the failure in setting the position of the supply roller for the decalcomania paper to a central standard can thus be prevented.
