[0008]

【Example】

 Hereinafter, the embodiment of the present invention shown in FIGS. 1 to 4 will be described. In the figure, reference numeral (1) is a cassette holder for accommodating the cassette (A) so that it can be moved up and down from above, and is a loading release position that has moved to the front, and it can be moved from the vertical position to the front through the horizontal axis (2) at the lower end. It is attached to the casing (9) of the cassette deck so that it can be rotated to the eject position that is inclined to the bottom. The horizontal axis (2) of the cassette holder (1) is installed so as to be movable back and forth along a horizontal long hole (8) formed in the frame portion of the device, so that the cassette holder (1) is vertical. It is configured so that it can move from the loading position in Fig. 1 to the loading release position slightly forward in the posture. The mechanism for moving the cassette holder (1) in the front-rear direction is formed by a plunger or the like, but the description is omitted because it complicates the drawing.

The cassette holder (1) is provided with a lift arm (5) rotatably supported via a base shaft (3). The lower end of the lift arm (5) has a receiving portion (7) that projects toward the cassette (A) housed in the cassette holder (1) and receives the bottom surface of the cassette (A). Moreover, the turning force is always applied upward by the spring (4). Further, there is provided a stopper (6) which prevents the lift arm (5) from rotating when the cassette holder (1) is in the vertical position in the loading position of FIG. In the embodiment, the stopper (6) is formed in the form of a groove that is open toward the front, and the receiving portion (7) is fitted into the groove-shaped stopper (6) to allow the lift arm (5) to move. Rotation upwards is blocked.

Further, an inclined cam surface (6a) which is inclined obliquely upward is formed at the tip of the groove-shaped stopper (6). The inclined cam surface (6a) keeps the cassette holder (1) in a vertical posture as shown in Fig. 2 and after moving it to the forward non-loading position, the cassette holder (1) is inclined forward. It is formed so as to rotate the lift arm (5) upward by guiding the free end of the lift arm (5) when the lift arm (5) is rotated to the eject position. As a result, as shown in FIG. 3, the cassette (A) can be automatically lifted upward in association with the rotation of the cassette holder (1). On the contrary, when the cassette holder (1) is rotated from the eject position inclined forward to a vertical posture, the lift arm (5) is rotated clockwise by being guided by the inclined cam surface (6a). It can automatically return to the state of 2 and store the cassette (A) in the proper position of the cassette holder (1). In the figure, reference numeral (11) is a receiving plate that picks up and holds the cassette (A) when the cassette holder (1) returns from the eject position to the loading position, but omits this and directly lifts the lift arm ( You may scoop at the receiving part (7) of 5).

5 to 8 show an embodiment in which the movement mechanism portion of the cassette holder (1) is slightly modified, and the cassette holder (1) has an upper portion of the support arm (1a). It is pivotally supported at the upper end by a pivot (12). A slide pin (13) protruding laterally is formed in the lower part of the cassette holder (1), and is slidable in a guide hole (15) provided in the casing (9) extending in the front-rear direction. Has been inserted. Thus, the cassette holder (1) is held by the support arm (1a) by the pivot shaft (12) and by the slide pin (13) in the casing (9).

The support arm (1a) is attached to the casing (9) of the cassette deck so that the lower end of the support arm (1a) can be rotated from the vertical posture to the eject position inclined forward through the horizontal axis (2). There is. Further, the spring (14) is pressed outwardly to the slide pin (13) of the cassette holder (1), which constantly presses the cassette holder (1) together with the support arm (1a) in the eject direction. However, at the loading position in FIG. 5, it is formed so that the posture can be maintained by a catch (not shown) provided separately.

A lift arm (5) is rotatably provided on the cassette holder (1) via a base shaft (3). The lift arm (5) has a receiving portion (7) that projects toward the cassette (A) housed in the cassette holder (1) at its lower end and receives the bottom surface of the cassette (A). In addition, the spring (4) constantly applies upward turning force. Further, a stopper (6) is provided to prevent the lift arm (5) from rotating when the cassette holder (1) and the support arm (1a) are in a vertical posture at the loading position of FIG. . Further, an inclined cam surface (6a) inclined obliquely upward is formed at the tip of the stopper (6). The inclined cam surface (6a) is moved by the support arm (1a) slightly forward as shown in FIG. 6 to move the cassette holder (1) to the non-loading position, and then the cassette holder (1) is moved. It is formed so as to rotate the lift arm (5) upward by guiding the free end of the lift arm (5) when rotating to the eject position inclined forward. As a result, as shown in FIG. 7, the cassette (A) is automatically moved upward by the receiving portion (7) of the lift arm (5) in conjunction with the rotation of the support arm (1a) and the cassette holder (1). Can be lifted. Conversely, when the support arm (1a) is rotated together with the cassette holder (1) from the eject position inclined forward to a vertical posture, the lift arm (5) is guided by the inclined cam surface (6a). By rotating clockwise, the state shown in FIG. 5 is automatically restored, and the cassette (A) can be stored in the cassette holder (1) at an appropriate position. The rotation of the support arm (1a) may be manual or electric.

Although a typical embodiment of the present invention has been described above, the present invention is not necessarily limited to the above-described embodiment structure, and the scope of the invention having the constituent features and having the effect Of course, it can be appropriately changed and implemented.

[0015]

[Effect of device]

 Since the present invention is configured as described above, the cassette (A) is moved upwards in conjunction with the movement when the cassette holder (1) is rotated to the eject position inclined forward. This allows the cassette (A) to be easily attached and detached, and at the same time, the mechanism for lifting the cassette does not require any electric mechanism to be lifted in conjunction with the movement of the cassette holder (1). Since the operation is performed by the arm (5), the mechanism is simplified, and there is an excellent effect that it can be manufactured at low cost.
