Description

[Detailed Description of the Invention] The present invention relates to a locking member for an operation button device in, for example, a recording/reproducing device. This invention relates to a locking member for an operation button that allows the button to be locked.

Conventionally, in devices such as video tape recorders, which are one type of recording/playback device, various mode switching operation buttons cannot be operated when the cassette is in a cassette setup state without a tape cassette installed. Leave the lock plate of the device in the released position.

That is, in a video tape recorder that uses a tape cassette, when removing the tape cassette from the recorder main body, the eject button is operated to load the ARP wound around the head drum and rewind it back into the cassette. An operation is performed to store it in the

Therefore, if the eject button is operated without a tape cassette installed, the loading mechanism will be activated and the next time a tape cassette is installed, the tape will not be properly wound around the head drum. This may result in malfunctions such as running out of data.

To prevent such malfunctions, when the cassette set-up is in a state where no tape is attached, the lock plate is closed so that other operation buttons such as the eject button cannot be operated, as described above.

However, video tape recorders are equipped with a dew detection mechanism that detects dew and removes it when dew forms on the head drum.

Due to the nature of the material that makes up the head drum, dew condensation occurs on the head drum when there is a large temperature difference, and the tape sticks to the drum, making it impossible for the tape to run smoothly. Therefore, in order to prevent such accidents, the dew on the head drum is detected and removed.

In order to activate the dew detection mechanism and remove the dew from the head drum, it is effective to rotate the head drum to remove the dew uniformly and quickly without any uneven drying.

Of course, at this time, it is best to protect the tape if the head drum is not wound with tape, that is, in a cassette setup state.

In this way, in order to rotate the head drum in the cassette setup state, you may want to keep the eject button pressed, drive the motor, and keep the head drum rotating in the groove where dew is removed. be.

Also, for tape recorders that are connected to a timer to record once and then record again after a certain period of time,
There are some tape recorders whose power is turned off between the first recording and the second recording, and the record mode is suddenly released from the locked state.

Therefore, when attempting to record for the second time, recording becomes impossible.

In such a case, it is convenient to forcibly maintain the locked state.

In addition, some tape recorders with cue signals
When rewinding a tape, in order to protect the tape being rewound, in order to operate the rewind button, this button does not have a locking mechanism, so it may be necessary to continuously press it with a finger or the like.

However, in order to rewind the tape and search for the desired record, the user has to keep pressing the operation button, which is cumbersome.

Therefore, there is a desire to be able to maintain a locked state for a certain period of time.

In this way, in order to maintain the safety of the main body of the device, if you want to lock an operation button that cannot or will not be locked, if necessary due to the circumstances mentioned above, you must pinch the operation button with cleaning scissors or the like. I'm just trying to find one, but I don't have a suitable locking member.

Therefore, when using something like the above-mentioned washing scissors, it is impossible to reliably lock the operation button, and the operability is also extremely poor.

Therefore, the present invention is designed so that the operation button, which is configured so that it cannot be in the locked state as described above, can be locked as necessary. A high-friction body such as rubber is used to connect the upper surface of the operation button, that is, the upper surface of the operation button in the depressed state, and the downward direction of the operation button, that is, the operation button that is in the non-operating state, that is, the operation button in the non-depressed state. By fitting and holding the formed insertion piece and the holding portion, the positions of each of the operation buttons can be pressed and locked.

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

FIG. 1 is a perspective view showing a locking member 1 capable of locking any operation button of a so-called piano key style push-in operation button device arranged adjacent to each other in a series in a recording/reproducing apparatus. It is.

This locking member 1 is made of a high friction material such as rubber,
In the illustrated example, the upper surface 6b of the two operation buttons 6 and 8 in the operation button device 11.

8b or the lower surface 6a, 8a and press the operation button 6.8.
The insert pieces 2 and 3 that hold down the insert pieces 2,
3, and a holding section 4 that holds down the upper surface 7b or lower surface γa of one operation button 7 located between the two operation buttons 6 and 8.

The insertion pieces 2 and 3 are attached to the holding portion 4 as shown in the figure.
A notch 5 is formed between the insertion piece 2 on one side and the insertion piece 30 on the other side to form a U-shape.

(See FIG. 3) Furthermore, as shown in FIG.
The tips 2a and 3a are sloped surfaces.

The operation button 7 is pushed downward by the inclination angle θ1 of this inclined surface.
By forming the angle θ2 approximately equal to the angle θ2 between the locking member 1 and the operating buttons 6 and 8 that are not pushed into the housing, the locking member 1 can be fitted more deeply and can be securely clamped.

A state in which an arbitrary operation button of an operation button device in a recording/reproducing apparatus is locked using the locking member 1 described above will be described below.

For example, as shown in FIG. 3, from left to right in the figure, there is an eject button 6, a tape rewind button I, a stop chain 8, and a play button 9.
In order to lock the rewind button 7, which does not have a lock mechanism, among the operation button devices 11 that are uniformly arranged adjacent to the fast forward button 10, etc., the rewind button 7, as shown in FIG. With the rewind button 7 pressed downward, insert the insertion pieces 2 and 3 of the lock member 1 from the tips 2a and 3a side, and push the eject button 6 and the stop button 8 adjacent to the rewind button 7, respectively, from the lower surfaces 6a, 8a side and the holding part 4
Insert the rewind button 7 so as to press down on the top surface 7b.

Then, as shown in FIG. 5, the lock member 1 is held between the rewind button 7, the eject button 6, and the stop button 8 by the return force of the unillustrated spring of the rewind button 7.

Therefore, the unwinding La7 is pushed into the state 11 against the return force of the spring.

That is, one of the insertion pieces 2.3 formed into a wedge shape with a certain inclination is inserted into the lower surface 6a side of the eject button 6, and the other is inserted into the lower surface 8a side of the stop button 8, and the holding part 4 is wound around the notch 5. Press down on the upper surface 7b of the rewind button 7 so that the rewind button 7 fits.

Then, the rewind button 7, which does not have a locking mechanism, can be kept in the locked state.

In this way, the locking member 1 has its insertion piece 2,
3 is wedge-shaped with an inclination angle that matches the amount of push of the operation button, so it can be easily inserted into the operation button device 11, and since it is made of a high-friction material, it is difficult to remove. It is held without falling.

The rewind mode in which the rewind button 7 is pressed can be easily released by pulling the lock member 1 toward you.

Alternatively, when locking the eject button 6, push the stop button 8 downward, and with the eject button 6 also pushed downward, insert the insertion pieces 2, 3 of the locking member 1 from the free ends 2a, 3a side. The rewind button 7 may be inserted into the upper surfaces 8b and 6b of the stop button 8 and the eject button 6, respectively, and the rewind button 7 may be inserted through the notch 5 so that the holding portion 4 presses the lower surface 7a.

Then, the lock member 1 is clamped and held by the eject button 6, stop button 8, and rewind uO7 as shown in FIG. 6 due to the return force of the eject button 6 and stop button 8, and the eject Button 6 can remain locked.

As described above, by using the locking member according to the present invention, an operation button that does not have a locking mechanism can be arbitrarily locked as necessary.

Therefore, even if you can easily expose the video tape recorder as described above, or record at intervals with a tape recorder that uses a timer, the power may turn off midway and the recording mode Can be forcibly prevented from being released, allowing reliable recording.

Furthermore, even if the button does not have a locking mechanism, such as a rewind button, it is not necessary to keep pressing it with fingers, making it easier to operate.

Furthermore, since there is no mechanical connection member with the recording/reproducing device main body, there is no need for any work such as drilling holes in the device main body, and the appearance does not deteriorate.

In the above-mentioned example, the number of insertion pieces of the locking member is two, but the number of insertion pieces may be three or more if necessary.

Of course, even in this case, a notch through which the operation button is inserted is formed between one insertion piece and the adjacent insertion piece.
