Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation mode switching device for a tape recorder.

Operating modes: recording RFC, playback PLAY.

Fast forward FF, rewind REW, pause PAUSE.

Furthermore, various switching devices for creating unrecorded portions EDITOR 1 stop 5 rop have been developed and are on the market.
In the type arranged in tiers, the structure related to the 5TOP button production was complicated and lacked practicality.

The present invention was made based on these problems with the conventional ones, and it is a type in which the switching buttons are arranged in two stages, upper and lower. This is what we are trying to do.

Practical examples thereof will be described in detail below with reference to the accompanying drawings.

In the accompanying drawings, FIGS. 1 and 2 are a schematic front configuration diagram and a rear perspective exploded view of the main parts of a tape recorder equipped with an operation mode switching device according to the present invention, and in this embodiment, a group of switching buttons are shown. As is particularly clear from FIG. 1, the top row has a 5TOP stop button 1 and REW rewind buttons 2 located on both sides of it. It consists of an FF fast forward button 3, and the lower row is a PLAY button 4. R.E.
C recording button 5. PAUSE button6. and EDITO
It consists of the button γ for creating the R non-recording part.

Each of these buttons is connected to a lever 1' to 7', and is provided with a switch that locks the lever to its operating position and releases the lock to its original position, and
A lock plate 9 is provided at the lower stage to lock the pressed state of the switching button.

In such a configuration, in the present invention, only the lower PLAY button 4 and REC button 5 are configured to be interlocked, and the others are single-acting, and when the REC button 5 is locked, the PLA
When Y button 4 is pressed, RFC button 5 is released and PLAY button 4 is pressed.
is locked, and when both the PLAY and RFC buttons 4.5 are pushed in at the same time to lock them, both locks can be released by either the 5TOP button 1 or the electric plunger 10.

That is, as is clear from FIG. 3, behind the 5TOP button 1, there is a button whose upper end is connected to the iron core 10' of the electric plunger 10, and whose lower end is removable from the retaining part 9' of the lock plate 9. an automatic stop lever 11 which has a contact piece 12 and is pivoted 13 appropriately in the machine at a centrally restored portion; and a cam surface 1 that slides into contact with a cam protrusion 1' provided on the back surface of the 5TOP button 1 at its upper end.
5, and a manual stop lever 14 which has a contact protrusion 16 at its lower end that engages with the abutment piece 12, and which is pivoted 17 to a frame 18 at a centrally resting portion, and as described above, the PLAY button 4 , when the 5TOP button 1 is pressed in a state where both the REC buttons 5 are locked, the cam protrusion 1' rotates the manual stop lever 14 clockwise in FIG. 1 via the cam surface 15 in accordance with this pressing. This rotational force is transmitted from the abutment protrusion 16 to the automatic stop lever 11 to rotate it, and the abutment piece 12 of this lever 11 is used to push the lock plate 9 in the direction of arrow A in the figure. , simultaneously unlock the P LAY and RFC buttons 4.5.

Similarly, with both buttons 4.5 locked, the tape is wound onto a tape reel (not shown), and when it reaches its end, an auto-stop signal is sent to the electric plunger 10 by an appropriate means. When the plunger 10 attracts the iron core 10' and rotates the automatic stop lever 11 clockwise, the engagement between the contact piece 12 and the retaining portion 9' of the lock plate 9 is caused. Accordingly, the lock plate 9 is moved in the direction of the arrow A, and the above-mentioned PL
Unlock AY and RFC buttons 4.5.

Also, when PLAY button 4 is locked or PLAY button 4 and RFC
When the FF button 3 or the REW button 2 is operated while the button 5 is locked, an auto-stop signal is generated, current flows through the plunger 10, and the PLAY button 4 or the PLAY button 4 and the REV button 5 are released.

This invention has 5T each button of the operation mode switching device like soft soil.
The button row containing the OP button is divided into the button row containing the PLAY and RFC buttons, and the PLAY and RFC buttons are simultaneously locked, and the simultaneous locking is performed in conjunction with the operation of the 5TOP buttons. It has a manual stop lever that releases the lock, and an automatic stop lever that releases the lock at the same time in conjunction with an electric plunger that operates in response to detecting the end of the tape, so it has an extremely simple structure that makes it easy to press the PLAY button. This is an excellent idea that allows simultaneous locking of RFC buttons to be released manually or automatically.

[Brief explanation of the drawing]

1 and 2 are a schematic front view and a rear perspective view of the device according to the present invention, and FIG. 3 is a perspective view of the main parts. 1: 5 TOP button, 4: PLAY button, 5: REC button,
9: Lock plate, 10: Electric plunger, 11: L stop lever, 14: Manual stop lever.
