Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape player that reliably performs a tape running direction switching operation during a rewind operation.

Prior art The applicant first operates the fast-forward lever or the rewind lever to retract the head plate to release the pressure contact between the pinch roller and the capstan shaft to feed the tape at a high speed. In the case of, the tape running direction switching mechanism is operated, and the operating state of these levers is locked, and then the locked state of one of the levers is released by the operation between the music detection signal and one of the other levers. The fast-forward lever or the rewind lever is moved backward, and by the backward movement, the head plate advances to press the pinch roller against the capstan shaft, and in the case of the rewind lever, the tape traveling direction switching mechanism is operated again. When the tape running direction is restored to the previous state, and the fast-forward lever and rewind lever are simultaneously operated, the tape running direction switching mechanism Japanese Patent Application No. 1-134713 proposes a tape player configured to operate only the tape player.

However, according to the operation mechanism of the rewind lever in the tape player described above, the linear movement of the rewind lever causes the protrusion provided on the rewind lever to be provided in the V-shaped portion provided on the rotating part. Directly act on the protruding part of the tape to rotate the rotating part, and the rotation of the rotating part activates the tape traveling direction switching mechanism. ,
The rotating part and the tape traveling direction switching mechanism are reciprocally mounted on an auxiliary substrate provided on the upper part of the substrate of the container frame, and are disposed on the lower part of the substrate of the container frame. The protruding piece extends from the position of the rewind lever to the lower part of the substrate through the auxiliary substrate and the substrate, and is formed to be relatively long.
In addition, since the width cannot be made large due to the configuration, the protruding piece is often deformed in the manufacturing process or in the use process, so that the operation of switching the running direction of the tape is unreliable and the performance is impaired.

Therefore, the present application is intended to solve the above-mentioned inconvenience.

Means for Solving the Problems In order to achieve the above-described object, the present application includes a fast-forward lever and a rewind lever having a projecting piece so as to be reciprocally movable,
Each time the rewinding lever is reciprocated, the rotating piece is rotated by the protrusion to operate the tape traveling direction switching mechanism, and when both levers are simultaneously moved forward, the control lever is used. The tape rewind lever is configured to slide the sliding piece, and to rotate the rotating piece by the sliding of the sliding piece to operate the tape running direction switching mechanism. Each time the rewinding lever reciprocates, it acts on a projection provided on the lever between the sliding member and the sliding member to rotate in the same direction, and the rotation slides the sliding member. It is characterized by having a transmission piece interposed, and the transmission piece has a flat V-shaped projection acting on the projection,
Preferably, the projection has two working surfaces having a substantially 90 ° angle, and a contact surface that abuts the working surface of the protruding piece is substantially 45 °.
A fast-forward lever, a rewind lever, and a transmission part are formed on an auxiliary substrate disposed on the substrate, and a rotating part and a sliding part are formed on the substrate. And a sliding piece extending vertically and having a working piece acting on the control lever and the transmitting piece at the upper end thereof. .

Operation When the fast-forward lever and the rewind lever are simultaneously moved forward, the sliding part slides in the same direction via the control lever with the forward movement. Is rotated and the running direction of the tape is switched by the operation of the running direction switching mechanism of the tape. In the above description, when both levers are simultaneously moved forward, the forward stroke is regulated to be shorter than when these levers are individually moved forward, so that both levers are locked in the forward movement state. Never.

Further, when the rewind lever is independently operated in the forward direction, the projecting piece acts on the projecting part, and the transmitting piece turns, and the rotation causes the sliding piece to slide, and the sliding causes the turning. Since the moving piece rotates, the tape running direction switching mechanism is operated, the tape is switched to running in the reverse direction, and the rewind lever is locked in its forward movement state.

In this state, for example, when the inter-track detection signal is output, or when the fast-forward lever is operated in the forward direction, the rewind lever is unlocked in the forward-moving state, and the lever moves backward. The projecting piece again acts on the projecting part to rotate the transmitting piece, whereby the sliding piece slides and the rotating piece also rotates, thereby switching the running direction of the tape. When the mechanism is operated again, the tape is restored to the play state before operating the rewind lever, and the rewind lever is restored.

Further, the forward movement holding state of the fast-forward lever (2) or the rewind lever (3) is automatically released when the tape reaches the end position and when a music interval detection signal is generated.

Although the head plate (43) moves forward and not shown, one of the pinch rollers is pressed against the capstan shaft and the tape is running, and the fast-forward lever (2) and the rewind lever (3) Are both brought into the inoperative position by the restoring springs (7) and (8), and the contact piece (30) of the control lever (25) is connected to the second part (12) of the window holes (10) and (10) '. In order to feed the tape at a high speed in the rewinding direction from the state shown in FIG. 2 pressed against the (12) ', the rewind lever (3) is pushed against its spring (8) as shown in FIG. When moving forward, the second portion (12) 'of the window (10)' provided in the lever (3) during the forward movement process.
Is separated from the contact piece (30), but the other fast-forward lever (2)
Since the contact piece (30) is pressed against the second portion (12) of the window hole (10) provided in the control lever (25), the control lever (25) is held in an inoperative state, and the rewind lever (3) With the outbound movement,
The folded piece (45) of the swing lever (44) comes into contact with the inclined edge (15) 'of the window (10)', and the swing lever (44) rotates counterclockwise in the drawing. As a result, the head plate (43) retreats in the non-play direction due to the contact between the rising rib (43) 'and the claw piece (47). Then, as is well known, the pressure contact with the pinch roller is released to the capstan shaft, and the tape is fed at high speed.

On the other hand, the projecting piece (19) provided on the rewind lever (3) goes straight, and in the process, acts on the projecting part (21) of the transmitting piece (23) as shown in FIG. (23) rotates counterclockwise in the figure. Then, the square piece (2
2) presses the action piece (41) provided on the sliding piece (38), and the sliding piece (38) slides forward.
7) turns the turning piece (34) counterclockwise in the figure,
As a result, the running direction of the tape is switched, and the tape is fed at a high speed in the rewind direction. Then, the rewind lever (3) fully moves forward, and the protruding piece (19) is
When the vehicle gets over, the transmission piece (23) is restored,
The locking projection (3) e of the rewind lever (3) is connected to the locking member (5).
It is locked in the locking hole (51) of 2), and its forward movement state is locked as shown in FIG.

In this state, when the inter-song detection signal is generated or when the fast-forward lever (2) is moved forward, the locking member (52)
Is rotated against the restoring spring (53) to release the locking between the locking hole (51) and the locking projection (3) e of the rewind lever (3), and the rewind lever (3) is released. ) Is restored by the restoring spring (8), and in the process of returning, the projection (19) acts on the projection (21) of the transmission piece (23).
The transmission piece (23) rotates again in the counterclockwise direction in the figure, and the switching lever (33) of the tape traveling direction switching mechanism operates again, so that the tape is moved before the operation of the rewind lever (3). While returning to the running direction, the rewind lever (3) and the head plate (20) also return to the state shown in FIG. 2, and the rewind operation ends.

The above-described operation is the same when the fast-forward lever (2) is moved forward against the restoring spring (7) in order to feed the tape at a high speed in the forward direction from the state shown in FIG. FIG. 5 shows this state. In this case, since the fast-forward lever (2) does not have the protruding piece (19), the transmitting piece (23) does not rotate, and thus the tape is not rotated. The traveling direction switching mechanism does not operate.

Next, both levers (2) and (3) are simultaneously moved forward from the inoperative state in FIG. 2 so as to switch only the running direction of the tape.

Then, as shown in FIGS. 6 and 7, the window holes (10), (1)
Since the second parts (12) and (12) 'of (0)' are simultaneously separated from the contact piece (30), the control lever (25) pivots and follows the second parts (12) and (12) '. , The third part (13), (13) '
And the lever (2), (3) moves forward, and the contact piece (30), that is, the control lever (25) moves forward in the same direction against the spring (31). The movement causes the sliding piece (38) to move forward through the engagement between the action piece (41) and the engagement concave portion (28), so that the rotating piece (34) is inverted by the arm (37). The tape rotates in a clockwise direction, thereby activating the tape traveling switching mechanism, thereby reversing the traveling of the tape. In this state, the forward stroke of both levers (2) and (3) is limited by the long hole (27), and the forward movement state is not locked by the locking member (52). The plate (43) also does not retract. By releasing the forward movement, the levers (2) and (3) are simultaneously restored.

The relationship between the projection (21) of the transmission piece (23) and the projection (19) of the rewind lever (3) in FIG. 8 will be described in detail with reference to FIG. , Protruding piece (1
Assuming that the rotation angle α of the transmission portion piece (23) at the time when the transmission portion 9 moves by the stroke l is the straight line 9), the action portion (41) of the slide portion piece (38) is moved by the stroke l ′
When the stroke l 'is small, the amount of rotational displacement of the rotating part (34) is absorbed by the mechanical spacing that exists at least between the various parts constituting the tape running direction switching mechanism, There is a concern that the reliable switching operation of the tape running direction switching mechanism is impaired.

FIGS. 9 and 10 show another embodiment for solving this fear. The difference from the above-mentioned embodiment is that one of the inclined edges of the hole (20) of the transmission piece (23) is provided. A projection (55) provided along the rewind lever (3), which is preferably provided at a 90 ° angle without being bent in a U-shape, and which acts on the projection (55), is provided with the projection (55). Twisted at an angle of approximately 45 ° to match the slope P of the portion (55), the contact surface a is approximately 45 ° in plan view.
点 It is at the point of the corner.

That is, in FIG.
Is equal to the movement stroke 1 of the projecting piece (19) in FIG. 8, the rotation angle β of the transmitting piece (23) becomes α <β, and the stroke l ″ of the sliding piece (38). Also l '<
l ″, and the turning angle of the turning piece (34) can be made large.

Effect of the Invention As described above, according to the present application, the linear motion of the rewind lever is converted into the rotational motion of the transmission piece by the action of the projection and the projection, and the rotational motion is converted to the original tape. The structure is such that the tape is transmitted to the sliding portion provided as a means for operating the traveling direction switching mechanism to operate the tape traveling direction switching mechanism. Therefore, the operation of switching the running direction of the tape can be reliably obtained, and the projection has two working surfaces having a substantially 90 ° angle, and the contact surface which comes into contact with the working surface of the projecting piece. When the angle is approximately 45 °, the rotation angle of the transmission portion can be made larger than the movement stroke of the projection, and the tape traveling direction switching mechanism can be performed without lengthening the operation stroke of the rewind lever. Can operate more reliably It has the advantage.
