摘要： PURPOSE:To inhibit the shift of a cassette carrier when a cassette is mounted on the carrier in a wrong posture and in a wrong direction, by providing the 1st and 2nd members which are actuated by the cassette mounted in a correct direction. CONSTITUTION:A cassette carrier shift preventing member consists of a slider 78 which can slide toward the rear part of the right wall part 70b of a cassette holder 70 and in directions of arrows K and L. A slider 79 provided at the back of the left wall part 70c of the holder 70 can slide also in directions of arrows K and L. When no cassette is mounted on a cassette carrier, the carrier is lifted to have a contact with a projected part. Both sliders 78 and 79 move down toward the arrow L when the cassette is mounted completely on the carrier in a correct posture. Then the cassette carrier can move horizontally. In case the cassette is mounted on the carrier in a wrong posture, one of the sliders 78 and 79 cannot move to the arrow L direction. Thus the cassette carrier has no shift.

摘要： PURPOSE:To attain automatic loading action f a tape recorder by giving an initial moving action to a sliding mechanism while holding a cassette, and actuating an automatic feed mechanism. CONSTITUTION:When a cassette 6 is put into a cassette stored part 2e, the free terminal of a slant part 4d of a cassette holding member 4 gets out of a slant guide bar 2j. When the cassette 6 is pushed further in the same direction, a hook bar 4f on the lower side of the part 4d hooks a hole 6a of the cassette 6. Thus the cassette 6 is held at a prescribed position in the part 2e. Then the cassette 6 is manually moved forward further, and a switch control bar 5d turns on a switch SW via an action bar 14. Thus a motor is revolved to move forward a feed member 10, and the cassette 6 moves forward automatically. Then a lock member 11 is turned counterclockwise, and a hook pin 12a gets out of a hook part 11c. Then a moving member 12 is moved to the front side by a spring, and a guide pin 1g is forcibly moved downward via a guide hole 2C. As a result, a cassette container structure matter is moved to the lower recording/reproducing position to set the cassette 6 at the recording/reproducing position.
摘要翻译：目的：通过在保持盒式磁带的同时向滑动机构施加初始移动动作，并且启动自动进给机构，来实现磁带录像机的自动加载动作。构成：当盒6被放入盒存储部分2e中时，盒保持构件4的倾斜部分4d的自由端从一个倾斜导杆2j中出来。当盒6沿相同方向被推动时，部分4d的下侧上的钩杆4f钩住盒6的孔6a。因此，盒6被保持在部分2e中的规定位置。然后，盒6被手动地向前移动，并且开关控制杆5d经由动作杆14接通开关SW。因此，马达被旋转以向前移动进给构件10，并且盒6自动向前移动。然后锁定构件11逆时针转动，并且钩销12a从钩部11c中脱出。然后，移动构件12通过弹簧移动到前侧，并且引导销1g经由引导孔2C被强制地向下移动。结果，盒式磁带盒结构物质移动到下部记录/再现位置，以将盒式磁带6设置在记录/再现位置。

摘要： PURPOSE:To reduce the vertical occupancy space for the entire mechanism of a driving arm by connecting the tip part of the driving arm to a moving element and simultaneously attaching movably the base end part of the arm at a prescribed position of a peripheral part as a mobile fulcrum to minimize the vertical movement amount. CONSTITUTION:For an arm 17, the base end part is attached to a cam 14 via a pin 18 serving as a mobile fulcrum together with the tip part attached to an interlocking lever 3 respectively. Thus the arm 17 moves with rotation along a locus prescribed by a mobile pin 18 and groove hole 1 after the backward shift of the cassette holding stage, i.e., in accordance with revolutions of a worm gear 12 and the cam 14. As a result, the tip interlocking part 20 of the arm 17 has the linear horizontal and vertical movements along the hole 1 together with the lever 3. Therefore the height position of the part 20 has virtually no change during a horizontal shift of the cassette holding stage. As a result, for the vertical space to be secured for movement of the arm 17, it is sufficient to secure a range of the height T1 from the center O' of the gear 12 at the heighest position of the arm 17 at the areas higher than the center O'.
摘要翻译：目的：通过将驱动臂的末端部分连接到移动元件，同时将手臂的基端部可移动地设置在周边部分的规定位置，从而减小驱动臂的整个机构的垂直占用空间移动支点使垂直移动量最小化。构成：对于臂17，基端部分分别通过连接在互锁杆3上的端头部分，作为活动支点的销18与凸轮14相连。因此，臂17在盒式磁带保持台的反向移位之后，即根据蜗轮12和凸轮14的转动，沿着由可动销18和凹槽孔1规定的轨迹旋转移动。结果，臂17的尖端互锁部分20与杆3一起沿着孔1具有线性的水平和垂直运动。因此，在盒保持台的水平移位期间，部件20的高度位置几乎没有变化。结果，为了固定用于臂17的移动的垂直空间，足以在臂17的最高位置处将高度T1的范围从齿轮12的中心O'固定在较高的区域比中心O'。

摘要： PURPOSE:To increase the hooking force between a sector gear which turns an arm shaft and a driving gear and to prevent a fault to be caused at the rise of the cassette bottom plate, by attaching a push-up driving motor, the push-up driving gear and a gear train to a bracket which is freely rockably supported by a shaft attached to a device frame. CONSTITUTION:A stopper 27 set on a pressure arm 26 usually abutted on an edge 24a of a counter bracket 24 regardless of attachment or detachment between a driving gear 16 and a sector gear 11. A tension spring 30 having considerably large power is stretched between a point 31 on the bracket 24 and a point 32 on the arm 26. As a result, the stopper 27 is press-contacted to the edge 24a. Thus both the bracket 24 and the arm 26 rock in a body round a shaft 22.

摘要： PURPOSE:To prevent the damage of a cassette and a head due to erroneous operations by making it impossible that a reproducing operation rod is pushed in on the way of or before cassette loading and making it possible that the reproducing operation rod is pushed in when loading is completed. CONSTITUTION:When a reproducing operation rod 125 is pushed on the way of or before loading of a cassette A due to a loading gear 48, a tip bent part 125b of the reproducing operation rod 125 is stopped by a pawl part 113b of a slider stopping plate 113 because a bent part 113a of this plate 113 is brought into contact with the peripheral part of a cam part 48c. As the result, erroneous operations during and before cassette loading are prevented completely. Meanwhile, when the loading gear 48 is rotated to come to the position of the reproducing state, the bent part 113a of the slider stopping plate 113 is dropped to a step part 48a of the loading gear 48, and therefore, the plate 113 is turned clockwise, and the pawl part 113b is escaped. Thus, the reproducing operation rod 125 can be pushed, and the reproducing operation is possible.
摘要翻译：目的：为了防止由于错误操作而导致的盒式磁带和磁头的损坏，使得再现操作杆不可能在盒式磁带加载之前或之后被推入，并且使得在加载时可以将再现操作杆推入完成了。构成：当再现操作杆125由于加载齿轮48而在盒A的装载之前或之前被推动时，再现操作杆125的尖端弯曲部125b被滑块的棘爪部分113b停止板113由于该板113的弯曲部113a与凸轮部48c的周缘部抵接。结果，完全防止了盒式磁带加载期间和之后的错误操作。同时，当加载齿轮48旋转到再现状态的位置时，滑块止动板113的弯曲部113a下落到装载齿轮48的台阶部分48a上，因此板113转动顺时针旋转，棘爪部分113b逸出。因此，可以推动再现操作杆125，并且再现操作是可能的。
