Description

[Detailed Description of the Invention] The present invention relates to a recording/playback switching device for a tape recorder.The purpose of the invention is to have a simple configuration, easy to assemble, and to be able to change the operation direction of the recording operation button and the switching operation direction of the recording/playback selector switch. To make it possible to surely perform a recording/playback switching operation even if they do not match.

Conventional tape recorder recording/playback switching devices transmit the operating force of the recording operation button directly to the recording/playback selection switch.
Since the operation is switched from playback to recording, it is necessary to make the direction of operation of the recording operation button and the direction of operation of the recording/playback changeover switch coincide to some extent.

Therefore, the position of the recording/playback switch is almost uniquely determined by the position of the recording operation button, making it impossible to utilize space effectively.

That is, for example, no matter how much free space there is on the printed circuit board on which the recording/playback selector switch is mounted, it is difficult to freely place the record/playback selector switch in that area.

Therefore, the present invention eliminates these conventional drawbacks, allows reliable recording and playback switching even if the recording and playback switch is arranged relatively freely, and also simplifies the configuration and facilitates assembly, reducing costs. An example of this will be described below with reference to the drawings.

In the figure, 1 is a recording button which can be rotated around an axis 2.

This shaft 2 is supported between bent pieces 4a, 4a (only one is shown in the figure) of a board 4 attached to a cabinet 3 made of synthetic resin.

A recording operation lever 5 is attached to the back surface of the board 4 so as to be slidable in the vertical direction.

A protrusion 1a provided on the recording button 1 is engaged with this lever 5, and when the recording button 1 is pressed downward, the lever 5
is moved upward and held in position by a locking mechanism (not shown), and when this holding is released by pressing a stop button (not shown), etc., the lever 5 is moved by the force of a spring (not shown) suspended from the lever 5. 5 is moved downward and returned to its original position.

A leaf spring 6 is fixed to the recording operation lever 5 at one end thereof.

An operating piece 7a of an operating lever 7 is in contact with the upper surface of the leaf spring 6.

The actuating lever 7 is formed into a U-shape by bending a plate material, and a through hole through which the pivot shaft 8 is inserted is provided on both sides thereof.

A bearing 9 for receiving this support shaft is provided integrally with the cabinet 3 made of synthetic resin.

Further, a groove 8a is formed on the outer periphery of the support shaft 8, and an elastic tongue piece 9a that is engaged with the groove 8a is integrally provided on the bearing 9.

Note that 9b indicates an opening.

Therefore, when the through hole of the operating lever is aligned with the through hole for the support shaft 8 provided in the bearing 9 and the support shaft 8 is pushed in, the tip protrusion of the elastic tongue piece 9a of the bearing 9 is inserted into the groove 8a of the support shaft 8. When engaged, the support shaft 8 is positioned, and the actuating lever 7 is moved to the bearing 9.
is rotatably mounted on the

On the other hand, 10 is a printed circuit board mounted on the cabinet 3, and a recording/playback changeover switch 11 is mounted on this printed circuit board 10.

The changeover slider 11a of this recording/playback changeover switch 11 is normally pushed out by a spring 12, and the switch 11 is switched to the playback side and held.

The slider 11a is provided with a through hole 13, and the bent piece 7b of the operating lever 7 is also provided with a through hole 14, and the space between these through holes 13 and 14 is made of hard wire such as piano wire. They are connected by a connecting rod 15.

In the above embodiment, when the recording button 1 is pressed, the recording operation lever 5 slides upward, and the leaf spring 6 fixed to the lever 5 also moves in the same direction.

Then, the bent piece 7a of the operating lever 7 that comes into contact with the iron plate spring 6
is pushed up, and the operating lever 7 is rotated about the support shaft 8.

Furthermore, the slider 11a of the recording/playback selector switch 11 connected to the operating lever 7 via the connecting rod 15 is supported by a spring 12.
It moves to the recording position (left side in Figure 1) against this, and the electric circuit is switched to the recording state.

Further, when the recording operation lever 5 is returned to its original position, the recording/playback selector switch 11 is held in the playback position by the tension force of the spring 12, and the force of this spring 12 is applied to the connecting rod 15.
The actuating lever 7 is rotated through the lever 7 so that its bent piece 7a is held in contact with the leaf spring 6.

Therefore, the operating force applied to the slider 11a of the recording/playback switch 11 is determined by the respective tension forces of the leaf spring 6 and the spring 12, so as in the past, the spring pressure etc. Not only does it not require adjustment work and reliable installation work can be performed with a simple configuration, but also the work process is significantly simplified and costs can be significantly reduced because fastening parts such as screws are not required.

As explained above, according to the recording/playback switching device for a tape recorder of the present invention, the relative arrangement of the recording button and the recording/playback selection switch can be relatively freely set with a simple configuration, so that space can be effectively used. It is possible to perform a recording/playback switching operation that is easy to use and reliable.
