Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device for a tape recorder, and particularly to an operating device in which operations such as recording, stopping, and playback are performed by continuously moving one operating means. When the unit performs operations such as recording, stopping, and reproducing, a stop operation position is provided between the recording operation position and the playback operation position to prevent erroneous operation of the device.

Conventionally, when operating this type of operating device from the playback state to the stop state, if the operation knob is operated suddenly, it will pass through the stop position, reach the recording operation position, enter the recording state, and erase the tape by mistake. There were flaws.

The present invention prevents the recording state even if the operation from the playback state to the stop state is suddenly performed as described above, and also enables the operation from the stop state to the recording state to be performed without any trouble. An example will be explained using the drawings.

In FIGS. 1 and 2, 1 is a dictation recorder main body, 2 is a remote control unit connected to the dictation recorder main body 1 via a cord 3 by a connector 4, and has a speaker 5, a microphone 6, and an operation knob 7. have. In Figures 3 to 7,
Reference numeral 8 denotes a slider integrated with the operation knob 7, which includes a control contact piece 9, locking parts 10, 11, 12,
13, and is slidably guided by a shaft 14.

The blocking lever 15 is rotatably provided on a shaft 16 provided on the upper part 2a of the remote control unit 2, is biased clockwise by a spring 17, and is coated with highly viscous grease such as silicone grease (not shown). is applied between the shaft 16 and the shaft 16 to allow gentle rotation. The biasing rotation of the blocking lever 15 in the clockwise direction is prevented by a pin 18 provided on the upper part 2a of the remote control unit 2, as shown in FIGS. 3 and 5.

A drive pin 19 is provided on the slider 8,
It is configured to be able to engage with the control portion 15a of the blocking lever 15.

A blocking portion 15b formed by bending the blocking lever 15 comes into contact with the end portion 8a of the slider 8.

The ball 20 is pushed against the slider 8 by the spring 21.
The locking portions 10, 11, 1
2 and 13.

The device has the above configuration, and its operation will be explained next.

First, the playback operation will be explained. When the operating knob 7 is operated in the direction of arrow A from the stopped state in FIG. 3, the slider 8 is also slid in the direction of arrow A.
The ball 20 is engaged with the locking portion 11 and held in the state shown in FIG. 4. When the slider 8 is slid from the state shown in FIG. 3 to the state shown in FIG. and then rotated counterclockwise.

At the same time, the control contact 9 is also moved from the state shown in FIG. 3 to the state shown in FIG. 4, controlling the terminal board (not shown) to bring the dictation recorder body 1 into the playback state.

Next, the recording operation will be explained. Operation knob 7
When the slider 8 is operated in the direction of arrow B from the stopped state shown in FIG. 3, the slider 8 is similarly slid in the direction of arrow B, and the ball 20 is engaged with the locking portion 13 and held in the state shown in FIG. When the slider 8 is slid to the state shown in FIG. 5, the control contact piece 9 is also moved to control a terminal plate (not shown) to put the dictation recorder body 1 into the recording state.

Next, a case will be described in which a stop operation is performed in a recording state. When the operating knob 7 is operated in the direction of arrow A from the recording state shown in FIG.
2 and held in the state shown in FIG. At the same time, the control contact piece 9 is similarly moved to control a terminal plate (not shown) to bring the dictation recorder main body 1 into a stopped state.

Next, a case will be described in which the operation knob 7 is suddenly operated to the stop position from the reproduction state. When the operating knob 7 is suddenly operated in the direction of arrow B from the playback state shown in FIG. When the drive pin 19 and the control part 15a are separated, the blocking lever 15 is rotated clockwise by the spring 17, but the slider 8
slides quickly and the blocking lever 15 is rotated slowly due to the viscous resistance of the silicone grease, so that the end 8a of the slider 8 is stopped at the blocking portion 15b of the blocking lever 15 as shown in FIG. The slider 8 is engaged at a position slightly moved toward the recording state position from the state position, and therefore, further sliding of the slider 8 is prevented. When the operation knob 7 is released from the state shown in FIG. 6, the slider 8 is stopped by the ball 20 as shown in FIG.
The engagement state of the blocking portion 15b of the blocking lever 15 is released, and the blocking lever 15 returns to the state shown in FIG. 3, making it possible to perform a recording operation.

Regarding the stop operation from the normal playback state, the slider 8 moves at such a speed that it is not engaged with the control section 15a due to the rotation of the blocking lever 15, so that the stop is performed smoothly.

Of course, when the slider 8 is moved, the control contact piece 9 is also moved to control a terminal plate (not shown) to stop the dictation recorder main body 1.

As described above, in the present invention, when the operating means is abruptly stopped from the playback position and the operating means is still moved from the stopped position, the blocking member prevents the operating means from moving, causing the operating means to erroneously move to the recording position. In addition, the operation from the normal stop state to the recording state can be performed smoothly without any hindrance.This eliminates the major problem of erroneous erasure even if the operation is performed suddenly. The effect is huge.
