2. Description of the Related Art Recently, a headphone stereo called a headphone stereo, in which a headphone is used to listen to a reproduced sound of a magnetic tape, has become popular. Such a tape recorder has a reproduction function in a first direction and a first direction. A reproduction function in a second direction, which is the opposite direction to the above, is generally provided. The tape recorder having such a bidirectional playback function has an operation button for switching the playback direction.
Since the ultra-small tape recorder is restricted by the mounting position of such operation buttons, the location of the operation buttons for switching the reproduction direction becomes a problem. As a technique for solving such a problem, for example, there is a technique disclosed in Japanese Patent Laid-Open No. 59-71154.

[0003]

The above-mentioned publication describes a technique in which the reproducing direction is switched by using the reproducing operation button. However, such technique is not related to the traveling direction of the magnetic tape. Since the playback direction is switched by operating the playback operation button, there is a problem that the switching operation feeling is poor. The present invention intends to provide a reproducing direction switching method which is improved in this respect.

[0004]

According to the present invention, the switching operation of the reproduction direction from the reproduction state in the first direction to the second direction is performed by the second fast-forward operation button provided for performing the fast-forward operation in the second direction. The switching operation of the reproduction direction from the reproduction state in the two directions to the first direction is performed by the first fast-forward operation button provided for performing the fast-forward operation in the first direction.

Only the displacing pressure pin 56 is shown.

The tape recorder according to the present invention is constructed as described above. Next, the operation will be described. In the stopped state shown in FIG. 1, the sliding substrate 12, the first fast-forwarding operation lever 17 and the second fast-forwarding operation lever 21 are in the non-operating position. When the sliding base plate 12 is in the non-operating position, the trigger control pin 16 attached to the sliding base plate 12 abuts on the abutting portion 48 of the trigger member 44 to displace and hold the trigger member 44 at the illustrated trigger position. It is in the state of having done. When the trigger member 44 is in the trigger position, the regulating pin 49 formed on the trigger member 44 does not regulate the cam 57, so that the urging force of the spring 60 causes the switching gear 52 to mesh with the switching drive gear 50. It is in a broken state. However, the switching drive gear 5
Since 0 is in the non-rotating state, the switching gear 52 is not rotated. Further, in such a stopped state, the reproduction direction switching slide plate 1 causes the control lever 27 of the springs 18 and 22 for urging the first fast-forward operation lever 17 and the second fast-forward operation lever 21 toward the non-operating position. It is in a state of being held in the intermediate position by the urging force.

When the user presses the reproducing operation button 14 in the direction of arrow D in the above-mentioned stopped state, the sliding base plate 12 is displaced to the operating position against the urging force of the spring 13 and the sliding operation is performed. The engaging projection 15 formed on the moving board 12 engages with the first lock piece 8 formed on the lock member 6, and the sliding board 12 is locked and held in the operating position. When the sliding board 12 is displaced to the operating position, the regulation force applied to the trigger member 44 by the trigger control pin 16 is cut off, so that the trigger member 44 is rotationally displaced to the non-trigger position by the urging force of the spring 46, and the trigger is moved. The regulation pin 49 formed on the member 44 is in a state in which the regulation operation for the cam 57 is performed. When the sliding board 12 is displaced to the operating position, power is supplied to the electric motor to start rotation, and the rotation is transmitted to the switching drive gear 50. When the switching drive gear 50 starts rotating, the switching gear 52 engaged with the drive gear 50 is rotated counterclockwise in FIG. Then, when it is rotated to a predetermined position, the meshing with the switching drive gear 50 is released by the first toothless portion 54 provided in the switching gear 52, and the restriction pin 4 formed on the trigger member 44.
9 is engaged with the first blocking portion 58 formed on the cam 57, and the further rotation of the switching gear 52 is blocked. FIG. 6 shows a state in which such a switching operation is performed. When the regeneration operation is performed in this manner, the switching gear 52
Is rotated to a predetermined position, the reproduction direction switching slide plate 1 is displaced to the first position in the arrow A direction by the pressing force of the pressing pin 56 formed on the switching gear 52 against the edge 5a of the control hole 5. Be punished. The state shown in FIG. 2 shows a state in which such an operation is performed. When the reproduction direction switching sliding plate 1 is displaced to the first position, the reproduction direction switching sliding plate 1 and the connecting pin 3 cause Control lever 27 connected
Is pivotally displaced about the shaft 28 in the clockwise direction. When the control lever 27 is rotationally displaced in the clockwise direction, the rotary member 39 is rotated by the switching spring 34 attached to the first arm 31 constituting the control lever 27.
It is pivotally displaced counterclockwise about 0.
When the rotating member 39 rotates counterclockwise, the rotating member 3
The transmission gear 43 rotatably attached to the gear 9 is in mesh with a gear (not shown) that transmits the rotation to the first reel shaft that winds in the first direction. During the reproduction operation, the drive gear 42 is rotationally driven at a low speed, so that the drive operation for reproduction of the first reel shaft is performed.
When the reproduction direction switching slide plate 1 is displaced to the first position, a first pinch roller (not shown) for driving the magnetic tape at a constant speed in the first direction is pressed against the first capstan shaft 62. The magnetic tape is in a state of being driven at a constant speed.
In this way, the tape recorder is in the reproduction operation state in the first direction, but in the reproduction state, the trigger member 44 is in the non-trigger position, and the roller 47 attached to the trigger member 44 is illustrated. Of the trigger control unit 4 formed on the reproduction direction switching slide plate 1 as described above.
It is in contact with the inclined portion 4a. Further, since the control lever 27 is rotationally displaced in the clockwise direction when in the reproduction state in the first direction, the edge 25a of the engagement hole 25 of the engagement pin 30 formed in the control lever 27. Due to the pressing force on the first fast-forwarding lever 17, the first fast-forwarding operating lever 17 is slightly displaced in the direction of arrow D. Therefore, the position of the first fast-forward operation button 19 is deeper than that of the second fast-forward operation button 23.

As described above, the operation is performed when the reproduction operation is performed from the stopped state. Next, the switching operation from the reproduction operation state in the first direction to the reproduction operation state in the second direction will be described. .. When the tape recorder is in the reproduction operation state in the first direction shown in FIG. 2, when the second fast-forward operation button 23 is pressed, the second fast-forward operation lever 21 to which the operation button 23 is attached causes the spring 22 to move. It is displaced in the direction of arrow D against the urging force of the lock lever 6, but at this time, the engagement protrusion 24 formed on the operation lever 21 does not engage with the third lock piece 10 formed on the lock member 6. Absent. When the second fast-forwarding operation lever 21 is displaced in the direction of the arrow D, the edge 26b of the engagement hole 26 formed in the operation lever 21 is attached to the second arm 33 constituting the control lever 21. In order to press 32, the control lever 27 is pivotally displaced about the shaft 28 in the counterclockwise direction. When the control lever 27 is pivotally displaced counterclockwise, the reproduction direction switching slide plate 1 connected to the control lever 27 is displaced in the arrow B direction by the connecting pin 3. The reproduction direction switching slide plate 1
Is displaced in the direction of arrow B, the trigger control section 4 formed on the sliding plate 1 presses the roller 47 attached to the trigger member 44, so that the trigger member 44 resists the biasing force of the spring 46. It is displaced to the trigger position which is clockwise. When the trigger member 44 is rotationally displaced to the trigger position, the regulation force applied to the cam 57 by the regulation pin 49 formed on the trigger member 44 is cut off. As a result, the switching gear 5 in which the cam 57 is formed
2 is rotated slightly counterclockwise by the pressing force of the spring 60 against the cam 57, and the switching gear 52 meshes with the switching drive gear 50. As a result of such meshing operation, the switching gear 52 is rotated counterclockwise again. In this way, the switching gear 52 is rotated counterclockwise, but when the predetermined position, that is, the second toothless portion 55 formed on the switching gear 52 is rotated to the position corresponding to the switching drive gear 50, the switching gear 52 is switched. Gear 52 and switching drive gear 5
The engagement with 0 is cut off. When the switching gear 52 rotates in this manner, the pressing pin 56 formed on the switching gear 52.
Contacts the edge 5b of the control hole 5 formed in the reproduction direction switching slide plate 1, and displaces the reproduction direction switching slide plate 1 in the direction of arrow B, that is, the second position. The reproduction direction switching slide plate 1
When the trigger member 44 is displaced to the second position, the trigger member 44, which has been displaced to the trigger position, pivotally returns to the non-trigger position, so that the restriction pin 49 formed on the trigger member 44 is formed on the cam 57. The second block 59 is engaged with the switching gear 52 to block further rotation. When the second fast-forward operation button 23 is operated in this manner, the reproduction direction switching slide plate 1 is displaced to the second position by the rotational force of the electric motor. The state shown in FIG. 3 shows a state in which such an operation is performed. When the reproduction direction switching slide plate 1 is displaced to the second position, the reproduction direction switching slide plate 1 is moved.
The control lever 27, which is connected by means of the connecting pin 3, is rotationally displaced counterclockwise about the shaft 28. When the control bar 27 is rotationally displaced counterclockwise, the rotary member 39 is rotated by the switching spring 34 attached to the first arm 31 constituting the control lever 27.
It is rotated and displaced clockwise about 0. When the rotating member 39 rotates clockwise, the transmission gear 43 rotatably attached to the rotating member 39 transmits the rotation to the second reel shaft that winds in the second direction (Fig. (Not shown). Then, during the reproduction operation, the drive gear 42 is rotationally driven at a low speed, so that the drive operation for reproduction of the second reel shaft is performed. When the reproduction direction switching slide plate 1 is displaced to the second position, the second
A second pinch roller (not shown) for driving the magnetic tape at a constant speed in the direction is pressed against the second capstan shaft 63, and the magnetic tape is driven at a constant speed. In this way, the tape recorder is in the reproduction operation state in the second direction, but in the reproduction state, the trigger member 44 is in the non-trigger position, and the roller 47 attached to the trigger member 44 is illustrated. As described above, the state is brought into contact with the second inclined portion 4b of the trigger control portion 4 formed on the reproduction direction switching slide plate 1. Further, since the control lever 27 is in the state of being rotationally displaced counterclockwise in the reproduction state in the second direction, the edge of the engagement hole 26 of the engagement pin 32 formed in the control lever 27. The second fast-forwarding operation lever 21 is slightly displaced in the direction of arrow D by the pressing force applied to 26a. Therefore, the second fast-forwarding operation button 23 is deeper in its position than the first fast-forwarding operation button 19. When the second fast-forward operation button 23 is operated in the reproduction operation state in the first direction, the switching operation to the reproduction operation state in the second direction is performed as described above. At this time, when the first fast-forwarding operation button 19 is operated, the first fast-forwarding operating lever 17 is displaced in the direction of arrow D, but the displacement of the control lever 27 by the operating lever 17 is absorbed by the switching spring 34, and the drive mechanism or the like. It has no effect on.

As described above, the switching operation from the reproduction operation state in the first direction to the reproduction operation state in the second direction is performed. Next, the reproduction operation state in the second direction is reproduced in the first direction. The switching operation to the operating state will be described. When the tape recorder is in the reproduction operation state in the second direction shown in FIG. 3, when the first fast-forward operation button 19 is pressed, the first fast-forward operation lever 17 to which the operation button 19 is attached is attached.
Is displaced in the direction of arrow D against the urging force of the spring 18, but at this time, the engagement protrusion 20 formed on the operating lever 17 engages with the second lock piece 9 formed on the lock member 6. There is nothing to do. When the first fast-forward operation lever 17 is displaced in the direction of arrow D, the operation lever 17 is moved.
The edge 25b of the engagement hole 25 formed in the control lever 2 is
In order to press the engaging pin 30 attached to the first arm 31 constituting the control lever 7, the control lever 27 is pivotally displaced about the shaft 28 in the clockwise direction. When the control lever 27 is rotated and displaced clockwise, the connecting pin 3
Thus, the reproduction direction switching slide plate 1 connected to the control lever 27 is displaced in the direction of arrow A. When the reproduction direction switching slide plate 1 is displaced in the direction of arrow A, the slide plate 1
The trigger control section 4 formed on the
The trigger member 44 is displaced to the clockwise trigger position against the urging force of the spring 46 by pressing the roller 47 attached to the. When the trigger member 44 is displaced to the trigger position, the switching gear 52 is rotated to a predetermined position as described above, and the reproduction direction is switched by the pressing force of the pressing pin 56 formed on the switching gear 52. The sliding plate 1 is displaced to the first position. As a result of performing such an operation, the tape recorder enters the reproduction operation state in the first direction shown in FIG.
As described above, when the reproducing operation in the second direction is performed, the first
When the fast-forwarding operation button 19 is operated, the switching operation to the reproduction operation state in the first direction is performed. At this time, if the second fast-forward operation button 23 is operated, the second fast-forward operation lever 2
1 is displaced in the direction of arrow D, the displacement of the control lever 27 by the operating lever 21 is absorbed by the switching spring 34 and does not act on the drive mechanism or the like.

As described above, the reproducing operation in the first direction and the second direction and the switching operation of the reproducing direction are performed.
The fast-forward operation in the direction and the second direction will be described. If the first fast-forward operation button 19 is pressed while the tape recorder is in the stopped state shown in FIG. 1, the first fast-forward operation lever 17 resists the urging force of the spring 18 and the arrow D
It is displaced to the operating position which is the direction. When the first fast-forward operation lever 17 is displaced to the operating position, the engagement protrusion 20 formed on the operation lever 17 engages with the second lock piece 9 formed on the lock member 6, so that the fast-forward operation is performed. The lever 17 is locked and held in the operating position. When the fast-forwarding operation lever 17 is displaced to the operating position, the edge 25b of the engagement hole 25 formed in the operation lever 17 presses the engagement pin 30 attached to the first arm 31 of the control lever 27. The control lever 27 is pivotally displaced about a shaft 28 in a clockwise direction. When the control lever 27 is rotationally displaced in the clockwise direction, the switching spring 3 attached to the first arm 31 of the control lever 27.
4, the rotating member 39 is rotated and displaced counterclockwise about the shaft 40. When the rotating member 39 rotates counterclockwise, the transmission gear 43 rotatably attached to the rotating member 39 winds in the first direction.
It is in a state of meshing with a gear that transmits rotation to the reel shaft.
During the fast-forward operation, the drive gear 42 is rotationally driven at a high speed, so that the drive operation for fast-forwarding the first reel shaft in the first direction is performed. In this way, the fast-forwarding operation state in the first direction is configured. At this time, the reproduction direction switching slide plate 1 is displaced to the first position with the rotational displacement of the control lever 27. Since it is in the non-operating position, the mechanism for regeneration such as the trigger member 44 does not operate. FIG. 4 shows such a fast-forward operation state in the first direction.

Although the fast-forward operation in the first direction is performed as described above, the fast-forward operation in the second direction will be described next.
When the second fast-forwarding operation button 23 is pressed while the tape recorder is in the stopped state shown in FIG. 1, the second fast-forwarding operating lever 21 resists the biasing force of the spring 22 and moves to the operating position in the arrow D direction. It is displaced. When the second fast-forward operation lever 21 is displaced to the operating position, the engagement protrusion 24 formed on the operation lever 21 engages with the third lock piece 10 formed on the lock member 6, so that the fast-forward operation is performed. The lever 21 is locked and held in the operating position. When the fast-forwarding operation lever 21 is displaced to the operating position, the edge 26b of the engagement hole 26 formed in the operation lever 21 presses the engagement pin 32 attached to the second arm 23 of the control lever 27. The control lever 27 is pivotally displaced about the shaft 28 in the counterclockwise direction. When the control lever 27 is rotationally displaced counterclockwise, the switching member 34 attached to the first arm 31 of the control lever 27 rotationally displaces the rotational member 39 about the shaft 40 in the clockwise direction. .. When the rotating member 39 rotates clockwise, the transmission gear 43 rotatably attached to the rotating member 39 meshes with the gear that transmits the rotation to the second reel shaft that winds in the second direction. It will be in a stale state. Then, during the fast-forward operation, the drive gear 42 is rotationally driven at a high speed, so that the drive operation for fast-forwarding the second reel shaft in the second direction is performed. In this way, the fast-forwarding operation state in the second direction is configured. At this time, the reproduction direction switching slide plate 1 is displaced to the second position with the rotational displacement of the control lever 27. Is in the non-operating position, the mechanism for regeneration such as the trigger member 44 does not operate. FIG. 5 shows such a fast-forward operation state in the second direction.

Although the respective operations in this embodiment are performed as described above, when the stop operation button 11 is pressed in each operation state, the lock member 6 resists the urging force of the spring 7 in the arrow A direction. It is displaced. When the lock member 6 is displaced in the direction of arrow A, the engaging projections 15, 20, and 24 of the first lock piece 8, the second lock piece 9, and the third lock piece 10 are formed.
Since the engagement state with is released, the sliding substrate 12, the first fast-forwarding operation lever 17 and the second fast-forwarding operation lever 21 which were in the operating position are returned to the non-operating position, and the tape recorder is stopped. Switching operation is performed.

As described above, when in the reproduction operation state in the first direction, the second fast-forward operation button 23 provided for performing the fast-forward operation in the second direction is operated to move in the second direction. When the reproduction direction switching operation is performed and the reproduction operation state in the second direction is performed, the first direction forward operation button 19 provided for performing the fast-forward operation in the first direction is operated to operate in the first direction. However, since the operation button for fast-forwarding that is operated for such switching is more prominent than the other operation button for fast-forwarding, it is easy to recognize the button to be operated. In addition, the switching operation can be easily performed even when both operation buttons are arranged close to each other.

In the present embodiment, the case has been described in which the operation switching is performed in the tape recorder configured to be operated by the user's operation force. However, the suction operation of the plunger and the rotation operation of the electric motor are used. It can also be implemented in a tape recorder configured to switch the operation.
