Abstract: PURPOSE:To reduce the planar size of a space necessary to dispose a tilting lever and to shorten a driving system by rotatably supporting low and high speed tilting levers to one supporting shaft. CONSTITUTION:A low speed tilting lever 39 for supporting a low speed transmission gear 44 inserted between low speed transmission systems 13, 34 and a driving system 17, and a high speed tilting lever 51 for supporting a high speed transmission gear 57 inserted between high speed transmission systems 35, 38 and the system 17 are rotatably supported to one supporting shaft 29. Thus, since a planar size of a space necessary to dispose the two levers 39 51 may be small and the gear of output stage for outputting the rotation of the system 17 to the gears 44, 57 may be a common one for the two transmission gears, the structure of the system 17 may be simplified and its system can be shortened.

Abstract: PURPOSE:To inhibit the overline of a tape while preventing the formation of a high-speed travelling mode at the same time as the completion of the formation of a stop mode by rotating a cam gear when a mode forming member is moved to the position of stop in such a manner that a tooth section is forwarded by a drive gear first and a slant face to be pushed is pushed by a section to be controlled. CONSTITUTION:Moving force to the position of stop by a resilient means 66 is energized to a mode forming member 62 while a slant face to be pushed is formed to the cam section 75 of a cam gear 69. The cam gear 69 is rotated when the mode forming member 62 is shifted to the position of stop, when a stop mode is formed, in such a manner that the tooth section 72a of the cam gear 69 is forwarded by a drive gear 24b turned by a motor first and the slant face to be pushed is pushed by a section 64 to be controlled. Accordingly, the overrun of a tape can be inhibited while preventing the temporary rapid- feed or rewinding of the tape at the same time as the completion of the formation of the stop mode.

Abstract: PURPOSE:To detect the stop of a rotation of a reel base only by expansion and contraction of an arm part without increasing the power consumption by allowing the mobile body of a detection lever to stop on a moving locus of the cam face, when a recording tape reaches terminal and the reel base has stopped, pressing a detection claw against this mobile body and allowing the arm part to be expanded and contracted. CONSTITUTION:On the tip part projected to the outside of a chassis substrate 5 of a cassette lock lever 89, a cassette holder opening/closing button 91 is provided, and by depressing this button, the lever 89 is moved in the direction as indicated with an arrow Y against energizing force of a spring 90, a locking piece 89a is also moved in the same direction and the engagement is released from a piece to be locked of a holder 79. In such a way, the holder 79 becomes a freely turnable state so that a cassette 4 can be inserted and detached, and also, when a fast forward lever 26 and a rewinding lever 27 are selected, a switch plate 29 is turned in the direction as indicated with an arrow D', and the movement of the lever 89 is inhibited. In this state, the arm part of the lever 89 is expanded and contracted and abuts against a detection claw, and the stop of reel bases 6, 7 can be known.

Abstract: PURPOSE:To house and arrange a gear system in a small space, by arranging a driving gear, a first notch gear, and a second notch gear respectively so as to enclose the periphery of an intermediate gear. CONSTITUTION:Since the driving gear 46, the first notch gear 38, and the second notch gear 39 are arranged so as to enclose the periphery of the intermediate gear 45, both notch gears 38 and 39 with different function are driven rotatably respectively by one intermediate gear 45 being always driven rotatably by the driving gear 46. And the driving gear 46 is also the gear to transfer a driving force to a pair of reel bases. In such way, it is possible to house and arrange the driving gear for driving the reel base required for a tape recorder, the first notch gear 38 for switching the reproducing (recording) mode, and the second notch gear 39 for switching a tape feeding direction, in the small space centering the intermediate gear 45.

Abstract: PURPOSE:To momentarily switch a mode from a reproducing (recording) mode to a stop mode, by rotating a notch gear without engaging it with a driving gear by a large notched area in a first notch part at the time of unlocking the notch gear in the reproducing (recording) mode. CONSTITUTION:Since the notched area of the first notch part 66 confronting with the driving gear 40 is set widely in the reproducing (recording) mode, when the notch gear 38 is unlocked in the reproducing mode, the notch gear 38 is rotated widely by the notched area of the first notch part 66 without being engaged with the driving gear 40. Therefore, a driving lever 50 is moved backward momentarily by the rotation of the notch gear 38, and the mode is switched to the stop mode. In such way, even when structure is the one to drive the driving lever 50 with the notch gear 38, it is possible to prevent an erroneous operation such that a pinch roller is left being adhered by pressing on a capstan, thereby, a magnetic tape is impaired, or a gear system for a reproducing (recording) mode is locked with the gear system for fast feeding/ rewinding, from being generate, at the time of switching the mode from the reproducing (recording) mode to the fast feeding/rewinding mode.

Abstract: PURPOSE:To simplify the structure of a device and to reduce the number of parts and the cost of the device by rotating an elastic arm fitted to a switching board by an operation rod to oscillate the switching board and press the switching board selectively against the reel of an intermediate gear. CONSTITUTION:The elastic arm 67 is rotatively fitted to the shaft part 72 of the switching board 66 supporting pivotally the 1st and 2nd idle gears 33, 34 and the long holes 49, 50 of the operation rods 45, 46 for quick winding and rewinding are engaged with supporting pins 70, 71 of the arm 67. When the fast feeding operation rod 45 is moved forward, the rod 45 presses the supporting point 70 of the arm 67 to rotate the arm 67, so that the switching board 66 is rotated in the counterclockwise direction. The idle gears 43, 34 are pressed and engaged again/with a driving gear 39 and a gear 30 of the reel turntable 7 respectively to execute the fast feeding. In case of rewinding, the operation rod 46 is operated. Since the oscillation of the switching board 66 and a limitter function are executed only by one elastic arm 67, the structure can be simplified and the number of parts can be reduced.

Abstract: PURPOSE:To perform fine adjustment with high precision by simple structure and operation, by pressing one end of a motor shaft, whose intermediate part is supported freely thrust-movably with respect to a motor body, toward the other end side with an elastic means and supporting the other end with an adjusting screw. CONSTITUTION:A lead screw part 30 is formed in one end part of a motor shaft 21 of a stepping motor body 20; and each time the motor shaft 21 is rotated, a moving object 52 engaged with the screw part 30 is moved in a prescribed direction insteps. The intermediate part of the motor shaft 21 is supported freely thrust-movably with respect to the motor body 20, and one end of the motor shaft is pressed toward the other end side by a spring piece 37 consisting of a spring material, and the other end is supported by the tip of an adjusting screw 38. When the screw 38 is turned forward, the front end of the motor shaft 21 is pressed, and therefore, it is thrust-moved backward against the elastic force of the spring 37; and when the screw 38 is turned in the reverse direction, the rear end is thrust-moved forward by the elastic force of the spring 37.

Abstract: PROBLEM TO BE SOLVED: To attain cost-down and reduction of the time for activating a filing system or the like in a system corresponding to a flash memory. SOLUTION: A logical/physical address translating table(TB) to be utilized for a file allocation table(FAT) is stored into a disk memory 1. Thus, it is not necessary for a microcomputer 109 in the main body of set to construct the logical/physical address translating TB at the time of filing system activation. Besides, since it is enough to read the required data part out of the logical/ physical address translating TB of the disk memory 1 and to utilize it, even when these data are stored in an internal RAM 111 of comparatively small capacity, the throughput of the microcomputer is not lowered. Therefore, an external RAM for holding the logical/physical address translating TB can be omitted.
