Title: Thermal printer
Inventor: MITSUI YOSHIHIRO
IPC: B41J2/32
Filed: 1979-04-27
Abstract: PURPOSE: To provide a thermal printer as having the superior printing quality, the low consumption of energy and the high durability by a method wherein a fabric material is used in a platen oppositely facing to a heater via a thermal paper.  
     CONSTITUTION: In a printer in which a head 1 having a heater has a width substantially the same as that of a paper, the head 1 pushes the thermal paper 3 against a platen 4 to perform printing, and a fiber material 51 is wound around a core 52 of the platen. As the fiber material, felt, jersey, velvet etc. may be applied, a close contact between the head 1 and the thermal paper 3 is further increased in its degree due to a resiliency and a deformation characteristics of the fiber to increase a printing quality. Further, a selection of such a material as having a low coefficient of friction may facilitate a rotation of the platen 4 even if no thermal paper is found. Even in the thermal printer in which the head 1 is moved laterally, the fiber material is similarly attached to the platen 4.

Abstract: PURPOSE:To enable a confirmation of operation of a motor valve after completion of an assembling of parts easily and within a short period of time by a method wherein a signal detecting circuit is arranged at an output part of a pulse motor driving circuit. CONSTITUTION:In case that a motor valve is driven, a pulse corresponding to each of four coils 4a of a pulse motor is outputted from a micro-computer 1. In response to this pulse, an output signal from a driving circuit 2 also becomes a pulse signal, the signal drives a pulse motor and then a motor valve 3 is opened (or closed). At this time, a buffer 5a connected to an output side of a pulse motor driving circuit 2 is operated such that its output side is at an L level while its input side is at an H level, and a load current flows from a power supply through a load resistor 5c and a light emitting diode 5b, resulting in that the light emitting diode 5b is lit. In case that an input side of the buffer 5a is at an L level, the light emitting diode 5b goes out. Accordingly, after completion of assembly of the parts, the light emitting diode 5b in a line of poor contact due to poor wiring in the motor valve 3 is not lit, resulting in that a detection of poor parts becomes possible.
