摘要： PURPOSE: To obtain the recording/reproducing device for a recording medium capable of exchanging the recording medium in a housing means in spite of during the recording or reproducing operation of the recording medium. CONSTITUTION: An MD reproducing device 1 is provided with a reproducing device 5, a magazine 3 arranged on the reproducing device 5 and laminated with plural trays for housing the MDs, and an elevation device 2 for vertically displacing along the laminated direction of trays. The MDs inserted to a holding part 2a of the elevation device 2 through an inserting/ejecting port 6f which is provided on the front surface plate 6c of a casing 6, are housed or loaded selectively to each tray of the magazine 3 or inside the reproducing device 5. In the elevation device 2, erroneous insertion preventing levers 29, 30 having groove detecting pieces 29b, 30b are provided so as to be projectingly or retreatingly displaceable in the holding part 2a.

摘要： PURPOSE:To decrease the drive torque of a cam mechanism by giving an angular displacement to a shaking member when a recording medium is located near the extreme position of the downstream side of the loading direction so as to part a stopper and a lock member slightly thereby giving the angular displacement to the shaking member. CONSTITUTION:When a grip member 13 is at the pause position, a lock member 35 provided to a shaking member 14 supporting the grip member 3 is in the 2nd angular position and engages with a locking lever 84 being a stopper. Thus, the weight of the grip member 3 in this case is not transmitted to a sliding projection 57 being a follower and a cam member 73 thereby causing only a possibly small force between the cam face 60 of a cam member 73 and the sliding projection 57. That is, when the grip member 3 is going to load a recording medium from the pause position, the drive torque required to drive the cam member 73 is reduced and then the constitution to generate the torque is miniaturized.

摘要： PURPOSE:To improve the control effect of azimuth for each drive of a tape and the durability of an azimuth control mechanism, by securing such a constitution where an individual control screw has a contact with an abutting part according to the tape driving direction, then the control screw moves away from the abutting part when the tape driving direction is changed. CONSTITUTION:A direction switch member 23 is shifted toward an arrow head A or B and therefore a cam member 21 is turned. Then an individual azimuth control screw has a contact with an abutting part for each tape driving direction. In other words, a control screw 19 has a contact with an abutting part 25 of the member 21. While a control screw 18 abuts on an abutting part 26. Thus the individual azimuth control is possible independently for each tape driving direction. At the same time, a follower part 20 is lifted via a cam part 24 during the switch of the driving direction. Thus both screws 18 and 19 move upward apart from parts 26 and 25 together with a head fixing plate 13. In such a way, the azimuth control effect is improved for each tape driving direction. Then the durability is also improved for an azimuth control mechanism.
摘要翻译：目的：为了提高方向盘对磁带驱动方向的控制效果和方位控制机构的耐久性，通过确保各个控制螺丝根据磁带驱动方向与抵接部分接触的结构，当带驱动方向改变时，控制螺钉移动远离邻接部分。构成：方向切换部件23向箭头A或B移动，因此凸轮部件21转动。然后，各个方位控制螺钉与每个带驱动方向的抵接部分接触。换句话说，控制螺钉19与构件21的邻接部分25接触。控制螺钉18抵靠在抵接部分26上。因此，对于每个磁带驱动方向可以独立地进行单独的方位控制。同时，在驱动方向的切换期间，从动件部分20通过凸轮部分24提升。因此，两个螺钉18和19都与头部固定板13一起向上与部件26和25一起向上移动。以这种方式，对于每个磁带驱动方向，方位控制效果得到改善。然后，对于方位角控制机构，耐久性也得到改善。

摘要： PURPOSE:To prevent any damage of the power transmission gear in the caption, by transforming any excessively large power between gears of a power transmission mechanism, generated by the inertial power of a motor, into friction and absorbing this power, between the end faces of the gears, when magnetic tape cassette loading or discharging operation is performed. CONSTITUTION:Power of a motor 101 is transmitted to the second gear 63 and the third gear 72 of a reduction mechanism 61, through the fourth gear 106. At this time, the notch of the second gear 63 faces to the right. Accordingly, the second gear 63 and the third gear 72 are driven in the direction of an arrow C1 shown in the figure. Since a spring is set to energize the end faces of the gears 63, 73, that make sliding contact with each other, as making them close with each other, power of the motor 101 is transmitted to the first gear 62 formed with the gear 63 in an integrated one body through the gears 106, 63, and transmitted to the other mechanism furthermore, when the gear 106 is engaged with the gear 63 at the other part than the notch. On the other hand, the driving state of the motor 101 is stopped in a condition that the gear 106 faces to the notch of the gear 63.
