摘要： PURPOSE:To load a cassette while it is kept upright by providing a matter which is revolved together with a cassette holder, a slide plate which supports freely rotatably the cassette holder, a rotor which transmits the revolving power to the matter to be revolved and a resistor respectively. CONSTITUTION:A motor pulley 12b is revolved with the revolution of a motor 12, and a work 14 connected to the pulley 12b is also revolved. Then a worm wheel 15 is revolved clockwise, and the revolving power of the wheel 15 is transmitted to a driving gear 19 to revolve the gear 19 counterclockwise. Thus a driving lever 20 is also revolved counterclockwise by centering on a support shaft 19a. In this case, the lever 20 receives the counterclock moment by the force of a resistance plate spring 30 via a resistor contact part 31. In such a way, the evil effect of an idle angle and ensures a smooth shift of a cassette holder 4 is eliminated. A main rotary gear 22 is revolved counterclockwise with the revolution of the lever 20, and therefore, a gear 25 to be revolved and engaged with the gear 22 is revolved clockwise centering on a holder shaft 23g. Then the holder 4 unified with the gear 25 is also revolved clockwise.

摘要： PURPOSE:To load a cassette while it is kept upright by using a matter which is revolved together with a cassette holder, a slide plate which supports freely rotatably the cassette holder, a rotor which transmits the revolving power to the matter to be revolved, and a cassette locking lever. CONSTITUTION:A motor pulley 12 is revolved with the revolution of a motor 12, and a worm 14 is also revolved. Then a worm wheel 15 is revolved clockwise. The revolving power of the wheel 15 is transmitted to a driving gear 19, and the gear 19 is revolved counterclockwise. Thus a driving lever 20 is also revolved counterclockwise by centering on a support shaft 19a, and therefore a main rotary gear 22 is also revolved counterclockwise. As a result, a gear 25 to be revolved and engaged with the gear 22 is revolved clockwise by centering on a holder shaft 23g, i.e., the revolving center of the gear 25. Thus a cassette holder 4 unified with the gear 25 is also revolved clockwise. In other words, a cassette locking lever 26 and a lever opener 24 are turned clockwise together with the holder 4 by centering on a holder shaft 23g. Thus the accuracy is improved for vertical and horizontal positions of the holder 4 supported by a slide plate 23 in such a simple constitution where only the gear 22 is driven.

摘要： PROBLEM TO BE SOLVED: To reduce contact pressure, prevent deterioration due to frictional heat, reduce size and enhance durability by forming a thrust bearing plate out of polyimide which is high in thermal deformation temperature. SOLUTION: A thrust bearing plate 12 is formed out of polyimide(PI) and in contact with a rotary shaft 7. The brush portion 2 of a brush arm 1 is in contact with a commutator 6. In the small-sized motor thus constituted, the polyimide(PI) constituting the thrust bearing plate 12 is elastically and plastically deformed by thrust loading on the rotary shaft 7 when the motor is in operation. Consequently, the thrust bearing plate 12 is provided with an appropriate area of contact with the rotary shaft 7 and the contact pressure between it and the rotary shaft 7 can be reduced. Further, since polyimide(PI) is high in thermal deformation temperature, deterioration in the thrust bearing plate 12 due to frictional heat is prevented.

摘要： PROBLEM TO BE SOLVED: To prevent clogging of a head by rotating a capstan shaft in the reverse direction by a certain extent at the time of temporary stop to reduce the tension acting on a magnetic tape and waiting for the start of reproducing in this state. SOLUTION: At the time of temporary stop, a capstan rotated in the forward direction till then is stopped and is next rotated in the reverse direction for a prescribed time T1 with a pinch roll 19 pressed to the capstan 50 to feed a tape 2 in the reverse direction. At this time, an idler gear T is rotated around a center gear shaft 9 in the CCW direction, but the time T1 is not enough for the idler gear 7 to be engaged with a gear part provided on an S reel base 4. Consequently, the S reel base 4 doesn't take up the tape 2 though the tape 2 is fed in the reverse direction, and then, the tension of the tape 2 is reduced around a cylinder 38. In this state, a rotary head cannot read out a signal from the tape 2 but can output a still picture stored in a memory just before.
