Description

The present invention relates to an operating device suitable for a small-sized tape recorder.

(B) Prior Art As described in Japanese Patent Laid-Open No. 54-104306, it is possible to easily switch between recording, reproducing, and rewinding states by a single lever-type switching means, which facilitates these switching operations. There is a tape recorder that can be used in.

(C) Problems to be solved by the invention In the tape recorder in which various operations can be switched by one switching means as described above, the rewinding state can be achieved only when the switching means is manually operated. It can be rewound, and like a normal tape recorder, it cannot be rewound continuously even after the rewind state is locked and the operating force is released. However, if you rewind or fast-forward the tape recorder in playback mode, the tape will be rewound or fast-forwarded during that operation, and the operation will be resumed. It is desirable that when the rewinding or fast-forwarding operation is performed, the operation member is locked so that the rewinding or fast-forwarding can be continuously performed even after the operation force is released. However, this is not possible with a tape recorder in which various operations are switched by the above-mentioned switching means.

The present invention also provides a main operation member for making a reproduction or recording state and a sub-operation member for making a rewinding state or a fast-forwarding state separately provided, thereby changing the operation position of the operation member to switch the operation state. The present invention provides a tape recorder capable of being in a review or cue state and a rewinding or fast-forwarding state.

(D) Means for Solving Problems The operation device of the tape recorder of the present invention has a main operation member that is brought into a reproduction or recording state by changing the operation position, and a rewinding state or a fast-forward state by changing the operation position. The sub-operating member, the first locking member controlled by the main operating member, and the second locking member controlled by the main operating member.

(E) Action The tape recorder operating device of the present invention is configured as described above, and when the main operating member is operated in either the right or left direction, it is brought into the reproducing state, and when the other is operated, it is brought into the recording state. And the main operating member is in the playback or recording state.
It is held by a locking member. When the main operating member is in the reproducing or recording position, the first locking member is controlled by the main operating member and is in the disengagement position with the sub operating member, so the sub operating member is not held at the rewinding or fast-forwarding position and operated. The tape is rewound or fast-forwarded only while the operation is in progress, and when the operation is stopped, the tape is put into the reproduction state. When the main operation member is in the stop position, the first locking member is in the engagement position with the sub-operation member, so when the sub-operation member is in the rewinding or fast-forwarding position, the sub-operation member is the first locking member. Holds in return or fast forward position.

(F) Embodiment An embodiment of the tape recorder operating device of the present invention will be described with reference to the drawings.

(1) is a main operation member slidably attached by pins (3) and (3) inserted into the long holes (2) and (2), and the knob (4) is slid in the direction of arrow A. By slide base (not shown)
By sliding the slider to the operating position, meshing the gear rotated by the motor with the tick-up reel shaft (not shown), and sliding the knob (4) in the direction of arrow B. In the same manner as in the above, and when the slide shaft is slid further in the direction of arrow B from the playback position, the drive transmission path of the tick-up reel shaft that has been connected up to that point is cut off, and the supply reel shaft meshes with the gear rotated by the motor Let it rewind. The main operation member (1) is a flat surface (5) (6)
A first engaging portion (8) having a recess (7) sandwiched between the flat surface (9)
Has a second engaging portion (12) sandwiched between the recesses (10) and (11).
(13) is a sub-operation member which is slidably attached by pins (3) and (3) like the main operation member (1), and by sliding the knob (14) in the direction of arrow A , The drive force from the motor is applied to the tick-up reel shaft in a different route from that during playback, the tick-up reel shaft is rotated at high speed, and the tape is fast-wound.
When 4) is slid in the direction of arrow B, the rotational force from the motor is transmitted to the supply reel shaft to rewind the tape. The sub operating member (13) has a force which always returns to the stop position when the engaging piece (15) engages with the U-shaped spring (16), and the first engaging portion of the main operating member (1). First, second and third recesses (17) (19) (1) corresponding to the planes (5) (6) and recesses (7) of (8)
8) has been formed. (20) is a lever (22) pivotally supported by a shaft (21) and urged clockwise by a coil spring,
The first roller (23) mounted on the lever (22) and engaged with the first engaging portion (8) or the first, second and third recesses (17), (19) and (18) The first locking member, and (24) is a second locking member, which is a second locking member that is slidably mounted and connected to a slide base, and a second locking member that is mounted on the connecting plate (25). A second roller (26) engaged with the engaging portion (12).

Next, the operation of the tape recorder operating device of the present invention will be described.

First, the stopped state will be described. In the stopped state, as shown in FIG. 1, the concave portion (7) of the first engaging portion (8) of the main operating member (1) and the third concave portion (18) at the center of the sub operating member (13). ) First
The first roller (23) of the locking member (20) is engaged. The second roller (26) of the second locking member (24) is locked to the flat surface (9) of the second engaging portion (12) of the main operating member (1).

In order to record in such a state, the knob (4) is slid in the direction of arrow A to the recording position. Then, as described above, the gear rotated by the motor by the main operating member (1) meshes with the gear of the tick-up reel shaft to rotate the tick-up reel shaft and wind the tape. On the other hand, the main operating member (1) is arrow A
When it is slid in the direction, as shown in Fig. 2, the second roller (2
Since 6) is fitted in the recess (10) of the second engaging portion (12), the connecting plate (25) is slid in the direction of arrow C by the spring (27), and the slide base is also arrowed accordingly. A head (not shown) on the slide base is pressed against the tape by sliding in the C direction, and a pinch roller is pressed against the capstan via the tape. Therefore, the tape is run at a constant speed by the pinch roller and the capstan, and recording is performed by the head. This state is maintained by fitting the second roller (26) into the recess (10) as described above.

At the end of recording, slide the knob (4) in the direction of arrow B to the stop position to restore the state shown in FIG. 1 and stop recording.

To play back, slide the knob (4) in the direction of arrow B, which is the opposite of the above, to the play position, contact the head with the tape and press the pinch roller onto the capstan to fix the tape in exactly the same way as during recording. The tape is played at a high speed, and the circuit is switched to the playback state, so that the tape is played. The torque of the motor is applied to the tick-up reel shaft via the gear and the tick-up reel shaft is rotated. It is wound up. In this regenerated state, the second roller (26) is the main operation member (1).
Is engaged with the recess (11) of the second engaging portion (12), and the main operating member (1) is held in the regenerated state.

By the way, if the main operating member (1) in the playback position is moved to the arrow B
Sliding it in the direction shown in Fig. 3 to the review position,
Since the second roller (26) slides up the slope (28) of the recess (11), the connecting plate (25) is slightly returned in the direction of arrow D against the spring (27), and the contact state between the head and the tape is reduced. The shallow pinch roller is also separated from the capstan. On the other hand, the rotational force from the motor is transmitted to the supply reel shaft through the rewinding transmission mechanism, and the supply reel shaft is reversely rotated at high speed to rewind the tape. In this state, the second roller (26) has the recess (11) on the slope (28).
The second roller (26) slides down the slope (28) when the operating force is released, because the spring (27) constantly exerts a force to restore the original playback state. It is reengaged with the place (11) and brought into a regenerated state. That is, rewinding is performed only while the knob (4) is held at the review position by hand, and when the knob (4) is released, the review in the replay state is performed.

Also, in the regenerated state, the first roller (23) has the first engaging portion.
Since it is located on the plane (6) of (8) and is moved in the direction of arrow D, the first roller is placed in the first, second and third recesses (17), (19) and (18).
(23) is no longer engaged. Therefore, the sub-operation member (1
When 3) is slid in the direction of arrow B to the rewinding position, the rotational force from the motor is transmitted to the supply reel shaft via the rewinding transmission mechanism, and the supply reel shaft is reversely rotated at high speed to rewind the tape fast. However, with the U-shaped spring (16), the sub-operation member
Since the urging force in the direction of arrow A acts on (13), when the hand is released from the knob (14) of the sub-operation member (13), the sub-operation member (13) is returned to the stop position. Since the operation member (1) is still held at the reproduction position, it returns to the reproduction state.

Further, when the sub-operation member (13) is slid in the direction of arrow A in the replay state to be in the fast-forwarding state, the rotation speed of the motor is increased and the pre-opening state is brought about without changing the connecting plate (25). When the operating force of (13) is released, the sub operating member (13) is not held by the first locking member (20), so it is returned to the stop position by the urging force of the U-shaped spring (16). It On the other hand, since the main operating member (1) is still held at the playback position,
When the sub-operation member (13) is set to the stop position, the sub-operation member (13) is brought into a reproduction state.

As described above, when the sub-operation member (13) is operated when the main operation member (1) is in the reproduction position, the tape is rewound or pre-opened and reproduced only while the sub-operation member (13) is operated, and the hand is released. ) Was returned to the stop position, it was put into the replay state.The fast-open playback or review operation was explained, but at the time of fast-open playback or review operation, the sub-operation member (13) slightly slid the slide base toward the stop position. , The head is separated from the tape, the pinch roller is separated from the capstan, and the driving force from the motor to the tick-up reel shaft is released similarly to the case of operating the main operation member (1) and reviewing. I am doing this.

When the main operating member (1) is in the recording position, the sub operating member (13) cannot be operated or has no relation to the operation.

When the main operating member (1) is in the stop position and in the stopped state,
When the sub operation member (13) is operated, fast-forwarding or rewinding can be continued even after the hand is separated from the sub operation member (13). For example, as shown in FIG. 4, when the sub-operation member (13) is slid in the direction of arrow A, the rotational force from the motor is transmitted to the tick-up reel shaft through the fast-forward mechanism, and the tick-up reel shaft rotates at high speed. Take up the tape and fast forward. At this time, the first roller (23) of the first locking member (20) is engaged with the recess (7) of the first engaging portion (8), and the first roller (23) moves in the direction of arrow C. Since it is located, the first recess (17) of the sub operation member (13)
The first roller (23) is fitted to the sub-operation member (13) at the fast-forwarding position to continue fast-forwarding the tape.

When the auxiliary operation member (13) is slid from the stop position in the direction of arrow B to the rewind position, the rotational force from the motor is transmitted to the supply reel shaft through the rewind mechanism to rotate the supply reel shaft. Rewind. At this time as well, the first roller (23) engages with the second recess (19) as in the fast-forwarding state, and the sub-operation member (1
Hold 3) at the rewind position and continue rewinding.

As described above, by operating the sub-operation member (13) when the main operation member (1) is in the stop position, it is possible to continuously rewind or fast-forward even after the operation force is released, and it can be manually By returning the sub-operation member (13) to the stop position, the rewinding or fast-forwarding can be stopped to bring it into a stopped state.However, the main operation member (13) can be held in the rewinding position or the fast-forwarding position. Even when 1) is operated, the engagement between the first locking member (20) and the sub-operation member (13) is released. That is, when the sub-operation member (13) is at the fast-forward position as shown in FIG. 4, the main operation member (1) is slid in the direction of arrow A to the recording position shown in FIG. Then, the first roller (23) comes out of the recess (7) of the first engaging portion (8) and is positioned on the plane (5),
The first roller (23) is rotated slightly counterclockwise together with the lever (22) and retracted in the direction of arrow D. Therefore, the engagement between the first roller (23) and the first recess (17) is released, and at this time, the engaging piece (15) of the sub operating member (13) is attached to one leg of the U-shaped spring (16). Since the fixing piece (29) hits the other leg of the U-shaped spring (16), the urging force in the direction of arrow B acts on the sub-operation member (13). Therefore, the urging force of the U-shaped spring (16) causes the sub-operation member (13) to return to the stop position in the direction of arrow B, which causes a malfunction that the tape is fast-forwarded in the recording state. I will not be told.

The same applies when the sub-operation member (13) is held at the rewinding position, and when the main operation member (1) is set to the playback or recording position,
Since the roller (23) is located on the plane (6) or the plane (5) of the first engaging portion (8), the first roller (23) escapes from the second recess (19). The sub-operation member (13) is a U-shaped spring at this time.
At (16), since the urging force in the direction of arrow A is working, it is returned to the stop position in the same manner as described above.

(G) Effect of the Invention The operating device of the present invention is provided with the main operating member for setting the tape recorder in the reproducing state or the recording state and the sub operating member for setting the tape recorder in the rewinding state or the fast-forwarding state, and by the main operating member. A first locking member that locks the sub operating member in the operating position and a second chain that holds the main operating member in the operating position only when the locking operation is controlled and the main operating member is in the stop position. Since the lock member is provided, not only the normal operation of continuously performing the rewinding operation and the fast-forwarding operation even in the tape recorder configured to switch the operation by the lever operation, but also the rewinding operation only during the operation. It is possible to perform a reviewing operation for performing a quick play and a cue operation for performing a fast-listening reproduction, and the present invention exerts a very great effect when implemented in a tape recorder used in place of a memo. It is intended.
