In an external ROM 60 there are accumulated a plurality of decoding program codes corresponding to respective plural methods for compressing and encoding. A controller means 50 transfers the decoding program code corresponding to the method for compressing and encoding after changing thereof, from the external ROM 60 to an internal RAM 25. A DSP 22 starts decoding processing by using the decoding program code which is transmitted into the internal RAM 25.

Abstract: A card connector assembly having a card misinsertion preventive structure has: a front cover placed in front of two card connectors double-decked up and down, each having an insertion opening; a shutter pivotally supported by the front cover; and a pivotal shaft. The shutter has two lengthwise parallel planes perpendicularly intersecting each other in L-shaped cross-section. In the absence of a card inserted in any of the card connectors, the shutter allows any one of the two insertion openings to be open to the front of the front cover to enable insertion of a card from outside into any one card connector. When a card is inserted in one card connector, the shutter covers the insertion opening of the other card connector to prevent insertion of a further card from outside into the other card connector. This prevents, in advance, a connection error, thereby preventing discomfort to the user.

Abstract: An optical encoder is a reflecting triple grating type optical encoder. A light projecting section of the optical encoder which includes a combination of a bare chip LED and a first grating of a first pitch p1, irradiates a predetermined light. A photodetecting section of the optical encoder which includes a combination of a photodetector and a third grating of a third pitch p3 detects a movement of a self image. Each of the first grating and the third grating is disposed substantially parallel with respect to a scale, and a substantially parallel and substantially flat light transmitting area is formed in a predetermined portion of a surface of a detecting head. A light transparent member is disposed in a space between the surface of the detecting head, and the first grating and the second grating.

Abstract: A high density flexible wiring connection device comprises a flexible flat cable (FFC) having narrow-pitch conductors and a flat cable connector (FC connector) having a double-sided contact designed for narrow-pitch wiring and having upper and lower contact terminals. A supplementary wiring board having upper and lower wiring terminals is introduced to connect alternate ones and the other alternate ones of the narrow-pitch conductors of the FFC to alternate ones of the upper contact terminals and alternate ones of the lower contact terminals of the FC connector, respectively, thereby making the pitch of each of the upper and lower wiring terminals twice the narrow pitch of the FFC and the FC connector. The use of the supplementary wiring board to thus convert the wiring pitch makes it possible to prevent whiskers, even if formed on the contact terminals, from causing short-circuits between adjacent contact terminals and between adjacent wiring terminals.

Abstract: A partition 13a is provided at the almost center of a parallel sheet feed tray 13 in a main-scanning direction and recording paper sheets P1 and P2 such as postcards are mounted in two rows in parallel in the main-scanning direction. By bringing upper surfaces of the recording paper sheets P1 and P2 into contact with a pick roller 5, the recording paper sheets P1 and P2 are picked one by one per row and fed toward an inside of a housing 10. While the recording paper sheets P1 and P2 are conveyed in a sub-scanning direction with being arranged in parallel in the main-scanning direction, ink drops are discharged to both the recording paper sheets P1 and P2 with reciprocation of a carriage 2 with the ink cartridges 3 in the main-scanning direction. Thus, images are formed on the two recording paper sheets P1 and P2 simultaneously, and thereby shortening time necessary for printing a lot of recording paper sheets.
