Abstract: A small card adaptor into which a small card is inserted so as to be connected to a personal computer includes a small card identifying portion for identifying the kind of the inserted small card, and a controller for receiving an instruction issued by the personal computer based on the kind of the small card identified by the small card identifying portion and transferring the received instruction to the small card.

Abstract: A printer 1 is provided with a thin casing 10. Inside of this casing 10, a power supply substrate 500 is arranged above a disk tray 300 supporting a disk as a recording medium on which recording is performed by a recording head 101. Furthermore, a purge unit 400 purging ink of the recording head 101 is provided, and an ink container 435 of a first ink collector 430 which collects the ink after purge of this purge unit 400 is arranged on a lateral side of a conveying route of a recording paper 50 as the recording medium on which recording is performed by the recording head 101.

Abstract: A coprocessor is incorporated in a processor comprising a CPU, an instruction cache, a data memory, a bus controller, an interruption control section and a DMA controller. This coprocessor has a parallel sum-of-products arithmetic operation section, a comparator, an I/O register section, and a sum-of-products factor register section. A frame memory, provided on the input side, stores MUSE or NTSC signals digitized per pixel. The DMA is in control of the transfer of data between the input-side frame memory and the data memory as well as the transfer of data between a frame memory provided on the output side and the data memory. Pixel data stored in the data memory is processed according to broadcasting systems by the switching of sum-of-products factors on the basis of software.

Abstract: A tape traveling apparatus drives differentially a tracking control actuator and a tension control actuator by inputting simultaneously into a tension controller a tracking instruction signal inputted into a tracking controller, and variably adjusts an amplification of the tracking instruction signal inputted into the tension controller according to an output of a tension sensor for detecting a tension variation of a tape, thereby eliminating a differential error between the tracking control actuator and the tension control actuator.
