Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette tape recorder in which a tape cassette mounting section is configured to be substantially expandable and retractable.

Problems with the conventional configuration Conventionally, in cassette tape recorders,
By substantially expanding and contracting the tape cassette attachment part when the tape cassette is attached and not attached, the tape cassette is made smaller when it is not attached, making it more convenient to carry. It is known that the structure is as follows. In such a telescopic type cassette tape recorder, the main body of the cassette tape recorder is constructed to have the same size as the tape cassette, and the sub-body of the cassette tape recorder is slidably attached to the main body of the cassette tape recorder. Accordingly, the tape cassette mounting portion on the cassette tape recorder main body side is enlarged.
However, in the above-mentioned conventional telescopic cassette tape recorder, when an opening/closing lid is provided on the side of the cassette tape recorder sub body for loading and unloading the tape cassette, the opening/closing lid is opened/closed even in the contracted state other than the extended state. In particular, if the cassette tape recorder sub body side slides against the cassette tape recorder main body while the opening/closing lid is left open, there is a problem that the user may be given the illusion that the tape cassette can be attached even in the contracted state. It was hot.

OBJECTS OF THE INVENTION An object of the present invention is to provide a cassette tape recorder that can clearly indicate the state in which a tape cassette can be installed and can prevent its misuse.

Structure of the Invention In order to achieve the above object, the cassette tape recorder of the present invention responds to the opening/closing movement of an opening/closing lid rotatably attached to the side of the cassette tape recorder subbody which is slidable relative to the cassette tape recorder main body. The present invention is characterized in that the cassette tape recorder sub body is configured to prevent sliding movement relative to the cassette tape recorder main body.

DESCRIPTION OF THE EMBODIMENTS FIGS. 1 to 8 show an embodiment of the cassette tape recorder of the present invention.

FIGS. 1 and 2 are external views when expanded, and FIGS. 3 and 4 are cross-sectional views of the same expanded state. The slide plate 8 having bent portions 19 at both ends has guide holes 10 and 1 in its guide pieces 9 and 11.
The lid mounting plate 13 is slidably attached to the mechanism board 5 having guide pins 6 and 7 corresponding to the lid mounting plate 13 and has a bent portion 14 that is pivotally supported by a rotation shaft 15 provided in the bent portion 19. do. Furthermore, the bent portion 19 of the slide plate 8
The other shaft 18 of the stopper piece 21 is pivotally supported on one side by the shaft 20 of the lid mounting plate 13, and the other of the stopper piece 17 is pivotally supported on the other hand on the shaft 16 of the bent portion 14 of the lid mounting plate 13. Configure point links. At this time, the two axes 1 of the bent portion of the slide plate 8
A four-point link with fixed axes 5 and 20 is constructed.
Also, on the side wall of the cabinet 1, there are a stopper 23 in the rotation direction and a stopper 2 in the slide reduction direction.
2 together with a reinforcing wall 25, and further includes a hole 24 for shrinking when the opening/closing lid 4 fixed to the lid mounting plate 13 is closed.

5 and 6 show the opening/closing lid 4 in an open state. The four-point link moves the shaft 18, which is made up of the stopper piece 17 and the stopper piece 21, to move the stoppers 23, 2 in the rotational direction and slide reduction direction.
2 to constitute a stopper.

FIGS. 7 and 8 show a state in which the opening/closing lid 4 is closed and the slide mechanism is contracted. Stopper piece 17,
21 passes through the hole 24 of the cabinet 1,
Slide 8 is reduced.

Effects of the Invention As described above, according to the present invention, in a cassette tape recorder having a telescoping mechanism, it is possible to clarify the state in which the tape cassette can be installed when the opening/closing lid is open, and when the tape cassette is contracted This has the advantage that the erroneous operation safety mechanism can be configured simply and inexpensively, and the usability can be significantly improved.

Claims (1)

[Claims] 1. A cassette tape recorder subbody is slidably attached to the cassette tape recorder main body so that the tape cassette mounting portion on the cassette tape recorder main body side is enlarged, and the tape cassette attaching portion is rotated toward the cassette tape recorder subbody side. A cassette tape recorder characterized in that the cassette tape recorder is configured to prevent sliding movement of the cassette tape recorder sub-body relative to the cassette tape recorder main body when a freely attached opening/closing lid is opened.
