Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an operating device for a tape recorder.

Conventional configuration and its problems In recent years, tape recorders have been equipped with a queue function, which allows fast forwarding (queuing) and rewinding (review) during playback.
This made it possible to immediately play back the contents recorded on tape.

This playback operation is performed by locking the playback control lever and pushing in the fast forward/rewind lever, but during this operation, the playback control lever is not released and the fast forward/rewind control lever is returned to its original neutral position. The playback operation starts immediately upon returning to the position.

That is, the fast-forward and rewind operation levers must be locked for simple fast-forward and rewind operations, but must not be locked for playback operations.

Conventionally, in an operating device using, for example, a sliding lock plate, in order to realize the above-mentioned playback operation, a difference has been made in the lock strokes of the playback operating lever and the fast forward and rewind operating levers. That is, when the playback operation lever is locked and the fast forward/rewind operation lever is pushed in, the lock plate moves from the first position to the second position against the biasing force of a spring or the like that biases the lock plate in one direction. The lock plate is moved and held at the second position by the return force of the regeneration operation lever, such as a spring. At this time, the reproduction operation lever continues to be locked, but the fast forward and rewind operation levers are in a state where they cannot be locked.

However, with such a configuration, there is a lack of reliability in reliably holding the lock plate in the second position due to changes in the return force of the regeneration operating lever, changes in the lock plate biasing force, changes in the friction coefficient of the sliding part, etc. However, there was a drawback that the fast-forward and rewind operation levers locked during the playback operation. In order to solve this drawback, when the return force of the regeneration operating lever was increased, quality problems such as an increase in the operating force and a worsening of the operating feeling occurred.

Next, in order to ensure that the lock plate is held in the second position, a step is provided in the lock portion of the regeneration operation lever of the lock plate, and when the lock plate slides, the regeneration operation lever is moved to the step. Although a considerable effect was observed when engaging the lock plate at The problem of the return operation lever becoming locked occurred again.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
It is an object of the present invention to provide an operating device for a tape recorder that can reliably and smoothly perform a playback operation even if there are variations in the stroke of a lock plate.

Structure of the Invention The present invention is provided to lock the playback operation lever, the fast forward and rewind operation levers whose lock release strokes are smaller than the playback operation lever, and the playback, fast forward and rewind operation levers. and a lock plate in which a plurality of stepped portions are formed within a release stroke range of the regeneration operation lever in the lock portion for locking the regeneration operation lever, and the regeneration operation lever is locked. When the fast-forwarding/rewinding operation lever is pressed and the lock plate is activated when the fast-forwarding/rewinding operation lever is pressed, the lock plate is configured to engage with any one of the plurality of stepped portions.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a partial plan view when it is in a stopped state.
FIG. 2 is a right side view in that state.

1 is an operating lever for tape ejection, 2 is an operating lever for recording, 3 is an operating lever for playback, 4 is an operating lever for stopping, 5 is an operating lever for rewinding, 6 is an operating lever for fast forwarding, and 7 is an operating lever for pausing. Each lever has a tape ejection button 8, a recording button 9, a playback button 10, and a stop button 1 at the end of each operating lever.
1, rewind button 12, fast forward button 13,
Temporary stop buttons 14 are respectively attached, are rotatable about the operating lever support shaft 15, and are always biased in the return direction (clockwise in FIG. 2) by a spring (not shown).

In FIG. 1, each operating lever is represented by the cross section XX in FIG. 2.

Reference numeral 16 denotes a lock plate for locking each of the operating levers, which is slidable through narrow portions 18 and 19 provided on the left and right edges of the mechanical board 17, and is always biased in the direction of arrow A by a compression spring 20. ing.

If you press the playback button 10 from this state,
A spring (not shown) that biases the regeneration operation lever 3 to which the regeneration button 10 is attached in the return direction.
At the same time, the lock plate 16 rotates in the direction of the arrow B, against the biasing force of the compression spring 20 which biases in the direction of the arrow A, because the lock plate 16 rotates against the tilted portion 16b of the lock plate 16 and presses the tilted portion 16b. Slide to.

When the regeneration button 10 is further pressed, the regeneration operation lever 3 passes through the slope 16b of the lock plate 16, and the pressure of the regeneration operation lever 3 on the slope 16b is released, so that the lock plate 16 is compressed. Due to the biasing force of the spring 20, it slides in the direction of arrow A and returns to its original state, and as a result, the regeneration operating lever 3
is locked on the lock plate 16, and the playback operation is started.

3 and 4 are a partial plan view and a right side view, respectively, showing a state in which the regeneration operation lever 3 is locked to the lock plate 16.

Similarly, when performing individual operations such as recording, rewind, and fast forward, press the record button 9 and rewind button 1.
2. By pressing the fast-forward button 13, the lock plate 16 is slid to lock the recording operation lever 2, the rewind operation lever 5, and the fast-forward operation lever 6 to the lock plate 16, and start the operation. Also,
To change each of the above operating states to a stopped state, press the tape ejection button 8 or the stop button 9, and slide the lock plate 16 in the direction of arrow B using the tape ejection operating lever 1 and the stopping operating lever 4. This is done by moving the levers and unlocking the operating levers that perform each operation.

Next, the operation of Kyureview will be explained.

FIG. 5 is a partial plan view in the queue state, and FIG. 6 is a partial plan view in the review state.

As described above, the playback operation is performed by locking the playback operation lever 3 to the lock plate 16 and then pushing in the fast forward operation lever 6 and the rewind operation lever 5. During this operation, the playback operation lever 3 is locked. , and it is impossible to lock the fast forward operating lever 6 and the rewind operating lever 5 to the lock plate 16. Then, as soon as the fast-forward operation lever 6 and the rewind operation lever 5 are returned to their stop positions, the reproducing operation is started.

The above operation will be explained in detail below.

7 to 9 show the playback lock portion 16a, rewind and fast forward lock portions 16d, 1 of the lock plate 16.
6f, and the playback operating lever 3, rewinding and fast forwarding operating levers 5 and 6. FIG. 7 is a stopped state, FIG. 8 is a playing state, and FIG.
The figure shows the queue review state.

A lock stroke difference a is provided between the reproduction lock section 16a and the rewind and fast forward lock sections 16d and 16f. This lock stroke difference a is
This is the amount obtained by subtracting the release stroke c of the rewind and fast-forward operation levers 5 and 6 from the release stroke b of the reproduction operation lever 3. That is, a=b−c, b>c
It is composed of the following relationships.

In addition, the regeneration lock portion 16a is formed with a plurality of step-like steps 16c as shown in FIG. 7, and the regeneration operation lever 3 is engaged with one of the step portions 16c during the queue review. Lock plate 1
6 is rewound, and the fast forward operating levers 5 and 6 are held in a position where they cannot be locked.

When the regeneration operation lever 3 is locked in the regeneration lock portion 16a from the stopped state shown in FIG. 7, the regeneration state shown in FIG. 8 is entered. At this time, the lock release stroke of the regeneration operation lever 3 is b, and in this state, the regeneration operation lever 3 is moved to the lock portion 16.
It does not engage with any of the step portions 16c of a.

In order to perform the playback operation from the playback state shown in FIG. 8, the fast forward and rewind buttons 13,
Press 12 to fast forward with those attached,
Since the rewind operation levers 6 and 5 come into contact with the inclined parts 16g and 16e of the fast forward and rewind lock parts 16f and 16d, and press the inclined parts 16g and 16e,
The lock plate 16 slides in the direction of arrow B against the urging force of compression spring 20 which urges in the direction of arrow A. At this time, the maximum sliding stroke of the lock plate is c
, and the release stroke b of the regeneration operating lever 3
, the regeneration operation lever 3 continues to be locked (lock stroke a), and when the lock plate 16 is slid in the direction of arrow B by the maximum sliding stroke c, the regeneration operation lever 3 continues to be locked (lock stroke a). 3 is engaged with any one of the plurality of step-like step portions 16c of the regeneration lock portion 16a. As a result, the lock plate 16 is held in that position and does not return to its original position.

The state at that time is shown in FIG. 9. Since the lock plate 16 is held by the playback operation lever 3 and its position is regulated, as can be seen from the figure, rewinding and fast forwarding are possible in this state. It is impossible to rewind the operating levers 5, 6 and lock them in the fast-forward lock portions 16d, 16f. That is, by pressing the fast forward and rewind buttons 13 and 12 from the playback state,
After the fast-forward and rewind operations are prioritized over the playback operation and the playback state is set, the playback operation can be started immediately by simply releasing the press of the fast-forward and rewind buttons 13 and 12.

A plurality of stepped portions 16c formed on the playback lock portion 16a are connected to the rewind and fast forward operation levers 5,
This is provided in order to absorb variations in the position of 6, that is, variations in the maximum sliding stroke c of the lock plate 16 at the time of revving. 3 is a stepped portion 16
In order to define the position of the lock plate 16 by engaging with one of the step parts c, the fast forward and rewind operation levers 6 and 5 are not locked during the playback operation and can be operated reliably. Can be done.

Effects of the Invention In the present invention, the stepped portion that engages with the playback operation lever is selected from among a plurality of steps in accordance with the stroke of the lock plate operated by the fast-forwarding and rewinding levers. Even if there are variations in the stroke of the lock plate due to accumulation, warping, deflection, expansion and contraction due to temperature changes, etc. peculiar to molded parts, the lock plate will be reliably held at the activated position by the regeneration operation lever, and then Even if an attempt is made to lock the fast forward or rewind operation lever, it can be reliably blocked, so that a reliable and smooth playback operation can be performed.
