Abstract: A heat-sensitive transcription printer system 100 is made up of a heat-sensitive transcription ink sheet cassette 10 and a heat-sensitive transcription printing device 50 on which said heat-sensitive transcription ink sheet cassette is loaded. On the heat-sensitive transcription ink sheet cassette is bonded an IC label 20 having an IC memory 21, a power receiving/supplying coil 23 and a diode 24 connected to the IC memory 21 and a signal communication coil 22 for performing communication of signals between the IC memory 21 and the heat-sensitive transcription printing device. The inherent discrimination information is previously recorded on the heat-sensitive transcription ink sheet cassette 10 and can be read out from it electrically. In this heat-sensitive transcription printing device 50, the driving power is supplied from a power supply unit 55 through a power supply coil 61, power receiving/supplying coil 23 and the diode 24 to the IC memory 21.

Abstract: A tension balancer is disclosed for an ink ribbon adapted for a printer for thermally transferring an image onto the printing paper while moving the ink ribbon together with the printing paper, the printer including: a platen for moving a piece of printing paper wound around the platen; and a thermal head for pressingly contacting the ink ribbon, interposed between a supply reel and a take-up reel, against the printing paper on an outer circumference of the platen. The tension balancer contacts at its end face with the ink ribbon over a full width of the ink ribbon for applying tension to the ink ribbon. The tension balancer is substantially in the form of a plate. At least one projection may be provided on the end face of the tension balancer.

Abstract: A cassette tape recording and/or reproducing apparatus has a pair of movable reel tables, the center distance between which is automatically so adjustable as to coincide with the center distance between the reels of any tape cassette optionally selected from various types of tape cassettes.
