DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double cassette tape recording / reproducing apparatus capable of mounting two cassette tapes at a recording / reproducing position, and more particularly, to a means for aligning adjacent ends of two cassette holders.

[0002]

2. Description of the Related Art A double-cassette tape recording / reproducing apparatus in which two cassette tapes can be mounted at a recording / reproducing position in order to enable dubbing or the like of a cassette tape is known. FIG. 4 shows an example of such a double cassette tape recording / reproducing apparatus. The cassette holder 2 is attached to the housing 1 shown in the figure.
And 3 are rotatably supported. After the cassette tape is rotated to project from the housing and the cassette tape is inserted, the cassette tape is rotated to close the cassette holder and holds the cassette tape at the recording / reproducing position.

FIG. 1 shows a state where cassette holders 2 and 3 are closed (a cassette tape recording / reproducing position).
The cassette holders 2 and 3 are rotatably supported below (on the other side of the drawing). When the cassette holders 2 and 3 are closed (the cassette holders 2
On the right side and the cassette holder 3 on the left side).

Since the insides of the cassette holders 2 and 3 are not locked, a step (indicated by D in the drawing) occurs at the end near the cassette holder due to deformation of the cassette holder or the like, which impairs the quality of the product. If the hook for locking the cassette holder is arranged at the center, no step is formed, but the eject knob for opening the cassette holder must be arranged at the center, which is not preferable in design. In addition, if the hooks are arranged on both sides of the cassette holder, both hooks must be driven in synchronization with each other, so that the mechanism becomes complicated.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a simple mechanism for providing an end portion close to a cassette holder of a double cassette tape recording / reproducing apparatus. It is to provide a means for aligning.

[0006]

In the double cassette tape recording / reproducing apparatus according to the present invention, two cassette holders which rotate while holding a cassette tape are arranged side by side, and the outsides of the respective cassette holders are locked by hooks. In the double cassette tape recording / reproducing apparatus for holding the cassette holder at the cassette tape recording / reproducing position, when the cassette holder is locked by the hook, the close end of each cassette holder is provided on the housing side. It is configured to be pressed against a common deformable tongue piece.

[0007]

According to the double cassette tape recording / reproducing apparatus of the present invention, a common tongue piece whose ends at positions close to each other of the respective cassette holders are elastically deformed in a state where the two cassette holders are locked at the reproducing position. , And the adjacent ends of the respective cassette holders can be aligned.

Further, since the hooks for locking the cassette holders are arranged outside the respective cassette holders, the eject knobs can also be arranged outside, which is preferable in terms of design. In addition, the only members added to the conventional one are a tongue piece provided on the housing or a projection provided on the cassette holder, and these can be formed by integrally molding with the respective members. Can be applied.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A double cassette recording / reproducing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a double cassette tape recording / reproducing apparatus according to an embodiment of the present invention. The cassette holders 2 and 3 are rotatably supported by the housing 1 via shafts 4, 4,.

The cassette holders 2 and 3 are urged in the opening direction by a spring (not shown), and when the hook 5 is released, the cassette holders 2 and 3 are opened to the position shown by the two-dot chain line in FIG. The cassette tape 8 is inserted at that position, and the cassette tape 8 is mounted at the recording / reproducing position by pushing the cassette holder 2 or 3 to the position shown by the solid line in FIG.

In FIG. 2, a hook 5 is rotatably supported by a shaft 6 fixed to the housing 1, urged clockwise by a spring (not shown), and pressed against a stopper (not shown). I have. When the cassette holder 2 is pushed in, the hook 5 rotates once in the counterclockwise direction and then returns to the original position to lock the shaft 2b erected on the cassette holder 2. Similarly, the cassette holder 3 is locked on the left side in FIG.

When the eject knob 7 is depressed, the hook 5 is rotated counterclockwise by a connecting member (not shown), and the hook 5 is released. An ejection knob for releasing the lock of the cassette holder 3 is also provided on the left side of the housing 1 in FIG.

The housing 1 is provided with a tongue piece 1a having a hinge structure shown in FIGS. 1 and 3, and the cassette holders 2 and 3 are provided with protrusions 2a and 3a, respectively, so as to contact the tongue piece 1a. ing.

FIG. 3 shows a state where the cassette holder 3 is pushed into the cassette tape recording / reproducing position. When the cassette holder 3 is pushed in by hand, as shown in FIG. 3A, the cassette holder 3 is pushed in more than the stop position in order to rotate and lock the hook. At this time, the tongue piece 1a is pressed by the projection 3a and is largely bent downward. When the hand is released from the cassette holder 3, the elasticity of the spring causes it to move as shown in FIG.
Return to the stop position shown in. At this time, the tongue piece 1a is still slightly bent and is pressed against the projection 3a.

When the cassette holder 2 is also stopped at the cassette tape recording / reproducing position, its projection 2a is
The cassette holders 2 and 3 are brought into close contact with each other.

Although the embodiment is configured as described above, the invention is not limited to this. For example, a tongue piece provided on the housing may be protruded and pressed against the flat portion of the cassette holder. Further, a hook for locking the cassette holder may be fixed, and a shaft locked on the hook may be moved.

[0017]

According to the double-cassette tape recording / reproducing apparatus of the present invention, the two cassette holders are locked at the reproducing position, and the ends of the respective cassette holders at positions close to each other are elastically deformed. Is pressed against the tongue,
The adjacent ends of the respective cassette holders can be aligned.

Further, since the hooks for locking the cassette holders are arranged outside the respective cassette holders, the eject knobs can also be arranged outside, which is preferable in terms of design. In addition, the only members added to the conventional one are a tongue piece provided on the housing or a projection provided on the cassette holder, and these can be formed by integrally molding with the respective members. Can be applied.

According to the double-cassette tape recording / reproducing apparatus of the present invention, the common tongue piece in which the two cassette holders are locked at the reproducing position and the ends of the respective cassette holders at positions close to each other is elastically deformed. , And the adjacent ends of the respective cassette holders can be aligned.
