As is clear from FIG. 12, the limiter gear 1769 is rotatably supported by a limiter arm 7113, which is rotatably supported by the shaft 70 on the shaft 17, and the l/end table 68 is in the retracted position. 1, the limiter knob 71 is moved in the t1 direction in the figure (= J is applied to the spring 72 which is constantly engaged with the flywheel gear A753. At this time, the head stand 68 is When the pin 57a of the idler arm 57 engages with the square hole stepped portion 68c and the idler arm 57 makes one movement in the direction 1101 in the figure, the eye lug \759 does not mesh with the reel driver A761.

Then, when the head stand 68 moves to the forward position i row and enters the play state, the bush 68b of the head stand 68 swings and tightens the limiter arm 71 in the direction 51 in the figure, and the flywheel gear A7. 53 and the limiter gear 69 is released, and on the other hand, the engagement between the square hole stepped portion 68C of the head stand 68 and the pin 57a of the idler arm 57 is released.
The idler gear 1759 meshes with the reel driver A761 to drive the reel unit 60 at a constant speed.

1QtF In FIG. 10, a cam gear A781 is rotatably supported on the shaft 82 by a shaft 82.
This Camgear X781 has a driving force of 1 to 3
The signal is transmitted through the red and white gears 83a', 83b, and 83c. As shown in FIG. 13, the sensing arm 84, which has a pawl 84a that can be appropriately engaged with the cam 81a of the cam gear A781, is in an 'l' position relative to the sensing power lever 85.
It is supported by 4μ on the swinging arm 1 by 1l186. On the other hand, a go-shaped arm 87 is pivotally supported coaxially with the cam gear 781, and this shaped arm 87 engages with the pin 62a of the above-mentioned kensing 1 extra arm 62 at the lower end elongated hole 87a. There is C. When the reel unit 60 is rotating, the rt ranging removal arm 62 moves to the right or in one direction depending on the rotation direction, and the sensing arm 8
4 in the direction opposite to N5Bl in FIG. When the rotation of the reel unit 60 stops, the L-singing release arm 62 does not move, so the claw 84a of the ranging arm 84 is not held at the engaging position with the cam 81a by the action of the inner wall of the outer periphery of the cam gear 81. The sensing arm 84 is moved to the left in FIGS. 1-3 by the rotational torque of the cam gear 781. Ranging arm 84 and sensing power lever 85
Since the sensing arm 84 is connected to the sensing arm 84 via the shaft 86, the sensing power lever 85 also moves together with the sensing arm 84 against the elastic force of the spring 88. Sensing arm 84
When the engagement between the pawl 84a and the cam 81a of the cam gear A781 is disengaged, the restoring force of the spring 88 returns it to its original position.

As shown in FIG. 14, a reset arm 89 is swingably provided coaxially with the T-shaped arm 87 and biased clockwise in the figure by a spring 90. The sloped portion 89a at one end of the reset arm 89 protrudes toward the loading side of the cassette half as shown in FIG. When the cassette half is ejected by swinging in the a1 direction, the spring 9
14, and the other end 89b swings the ranging arm 84 in the counterclockwise direction in the figure. According to this, sensing arm 8
Even if the A-toy eject operation, which will be described later, is completed and the motor 50 stops immediately before the engagement between the pawl 84a of No. 4 and the cam 81a of the cam gear 81 is disengaged, the action of the reset arm 89 causes the reset rung arm 84 to stop. Claw 84a and Kamugi\78
Since the engagement with cam 81a of cam 81a can be reliably released, the next loading operation of cam 81a will not be hindered.

In FIG. 1, the selection lever 42 and the sensing power lever 85 are arranged in parallel with each other, and are depicted as being able to move downwards in the figure either individually or together. In addition, the selection lever 42 is a lock release lever 43.
~OMi 43'a is used as a working fish, and the L! (sensing movement) The lever 85 is movable between an engaged position and a non-engaged position, and its four parts 42'a engage with the bent part 85a of the sensing power lever 85 (11t).

When the tape ends and the ranging power lever 85 moves downward in FIG. 1 due to the sensing operation described in FIG. is driven by the sorting lever 712 in the same way as in the manual eject operation, so the eject operation is automatically performed at the end of the tape.

On the other hand, as shown in FIG. 16, during FF or REW, the F[lever 28 or the REW lever 29 presses the rising portion 42b of the sorting lever 42 with its tip, swings the sorting lever/12, and closes the sorting lever. Since the engagement between the concave portion 42a of 42 and the bent portion 85a of the ranging power lever 85 is released, even if the sensing power lever 85 moves due to the ranging operation, the sorting lever 42 does not move and the ejecting operation is not performed. do not have. As shown in FIG. 17, a lock arm 93 is provided which is swingably supported by a shaft 31a and biased by a spring 92 in the direction shown in the figure. , this lock arm 93

Since the separating bar 42 is swung and tightened, the ejecting operation is not performed as in the case of [Ni-Ishikake RtEW]. At this time, when only the sensing power lever 85 moves, as shown in FIG.
The lock arm 95, which was forced in the direction (q) and locked the head stand 68 in the backward position by engaging the bent portion 68d of the head stand 68 with its stepped portion 95a, is now moved by the sensing power lever 85. Since the falling portion 85b swings counterclockwise in the figure as shown in FIG. 19, the head stand 68 is unlocked.

In FIG. 18, the head stand 68 is engaged with the pins 91b of the pinch roller units 1 to 91 through the holes 68e, and when the head stand 68 is unlocked, the pinch roller unit 91 and the chassis 17 are connected. A forward force is applied to the head stand 68 by a spring 96 stretched therebetween. The head stand 68 also engages with an arm 98 swingably supported by the chassis 17 via @1197 at its front end rising portion 68r, and the arm 98 is attached in the direction of the lever 1 in the figure. A forward horn is also provided by the biasing spring 99 to move in the direction of the arrow. At the same time as the head stand 68 moves forward, the pinch roller unit 91 swings clockwise in the figure, and the pinch roller 100 moves forward. At the time of ejection, the arm 98 is rotated counterclockwise by the lever 101 which is returned by the biasing force of the spring 102 as shown in FIG. , it returns to its original state and is locked in the retracted position by the lock arm 95.

Next, the fast forward (FF') and rewind (REW) operations will be explained.

When the FF lever 28 is pressed as shown in FIG. 20 while the cassette is at 81'F4 and the tape deck is in play mode, the protrusion 28a of the FF lever 28 engages with the locking pin 93a of the arm 93. Te1: "Lever 28
is locked in the operating position, and the cam part 28b is fixed to the head stand 68 and presses and covers the head stand pin 102 in the right direction in the figure, so the head stand 68 moves back a little. and,
The pinch roller 100 retreats and is no longer in pressure contact with the °C chitop stamp 55, and at the same time the head 25 comes into light contact with the tape. At this point, as shown in FIG. 12, the pin 57a of the idler arm 57 is pushed down by each hole stepped portion 68C of the head stand 68, and the idler arm 57 is rotated in the direction shown in the figure. Reel drive gear
The meshing between 761 and idler gear A759 is released. On the other hand, at the same time, the head stand bush 6811 is disengaged from the limiter arm 71, so the limiter arm 71 is swung in the ItH1 direction in the figure by the force of the spring 72, and the limiter gear 769 is connected to the flywheel gear. 5
3 meshes with flywheel gear 5, and high-speed rotational torque is generated by flywheel gear 5.
3 to limiter gear 69, idler gear A774 and FF
It is supplied to the reel drive gear 61 via gear A778.

In this way, the tape deck performs a fast forward operation.

To stop the fast forward operation, press REW from the state shown in Figure 19.
When the lever 29 is pressed lightly, the protrusion 29a of the R lever 29 slightly presses the lock pin 93a to the right in the figure, and the protrusion 28a of the F lever 28 disengages from the lock pin 93a. FF lever 28 is spring 3
It is restored by the rebound force of 9, and Caret Detsuki returns to its original playing state.

Also, if a tape end condition occurs during fast forward operation,
The reel unit rotation stop sensing mechanism (first
3) is activated, and as explained in a3 of FIG. 18, the FF lever 28 is locked as the switching power lever 85 moves. At the same time, the head stand 68 moves forward and returns to the play state.

Next, when performing a rewind operation, press the RE W lever 29.
When the REW lever 29 is strongly pressed, the REW lever 29 is moved to the operating position as the protrusion 29a of the REW lever 29 engages with the lock pin 93a, as shown in FIG. Then, as in the case of FF, the head base pin 102 is pushed in the direction of the arrow by the cam portion 29b, so
The head stand 68 moves 137, and the meshing between the idler gear 1759 and the reel drive gear 1761 is released. At the same time, as shown in FIG. 11, the second arm 37 swings about the pin 38 in the backward direction in the figure in connection with the pressing operation of the REW lever 29, thereby causing the second arm 37 to engage the pin 79a. The switching lever 79 engaged through the slot moves in the direction of the arrow in the figure and moves the idler lever 79 downward in the figure, so the idler gear 74 moves linearly along the elongated hole 76 and connects to the reel drive gear 80. The limit gear 1769 and the idler gear 74 are meshed and the high speed rotation from 1 to
is supplied to the drive reel driver 1780 through which the rewinding operation is performed.

In addition, in the above embodiment, the FF lever 28 and R
Although the EW lever 29 is configured to be restricted from swinging by the shaft 31b engaged with the elongated holes 28b and 2'9b, the grille 3
The swing of each lever 28, 29 is restricted by the opening 34a of the shaft 3.
Since 1b can be omitted and the number of parts can be reduced, it is possible to further reduce the weight and cost of the device.

As explained above, according to the operating mechanism of the cullet deck according to the present invention, the longitudinal operating lever for actuating the controlled mechanism supported on the chassis member is attached to the bin member mounted on the chassis member. In the vicinity of the operating end, it is engaged so as to be slidable in the longitudinal direction and swingable around the bin member, and the swinging is restricted by a J in the frontage of the grill member with which the operating end engages. As a result, a relative positional shift occurs between the shutter 9 member and the grille member, making it difficult to reliably position the operating button of the operating lever relative to the opening of the Cb1 grille member. In addition, since the operating lever is a flexible one, the radius of one movement is large, so there is less chance of the operating button being tilted relative to the opening of the grille member.
Those with excellent appearance are ranked IIJ.
