By moving forward, this intermediate lever 13E3 presses the swinging part 96 toward the rear part j, and is used to move the force IY 1 to holder 98 from the lowered position to the raised position 1u. It is something.

Next, various switches and their arrangement will be explained.

It is clear from Figures 2 and 6 that there is a bracket 146 on the right side of sub-chassis B 95.
There are two switches 1.
47,148 are attached 1). switch 147
is used to switch the power to the cassette deck and a chiconer disposed near the cassette deck. Further, the switch 14ε3 is for operating the motor 24. Both switches 147 and 148 are both mechanically actuated upon insertion of the cassette half into the cassette holder 98.

A switch 149 for switching between F[ and REW is fixed on the front surface of the left end of the sub-chassis 11 shown in FIGS. 2, 7, and 18. This switch 1/19 is operated when the movable plays 1 to 52 attached to the recess 17-A are engaged.

In addition, j shown in Figure 15: sea urchin, ribfish p - sea 1
A switch 150 for cutting off the power supply to the cassette deck is fixed on the cassette deck 11. The switch 150 operates when the intermediate lever 138 is moved forward (moved backward).

The operation of the cullet deck having the above-mentioned slotted structure will be briefly explained along the operating procedure with reference to FIGS. 19 to 26.

First, the force [piece 1 to half 155 (shown in FIG. 19)] is inserted through the opening 2a of the housing 2 shown in FIG.
The cassette half is held in a cassette holder 98 as shown in FIGS. 9 to 21. As shown in FIG. 20, the cassette half 155 is attached to the cassette holder 9.
8, the right side member 100 moves rearward, and as a result, the swinging support shaft 98a of the cassette holder 98 falls into the recess 100b of the right side +A 100, and the force Can be moved to the lowering position.

J, Tension L TS 1 to HALF are set to the performance position.

Along with this half-insertion operation, the switches 144 and 148 shown in FIG. 6 are turned on, for example.
Power is turned on to the T-deck, and one motor 24 starts rotating. When the motor 24 rotates, the first
As shown in Figure 0, the small pulley 24a moves in the direction of arrow M.
Further, the pulley 23 is rotated in the direction of arrow N, and the pair of front and rear flywheels are rotated in the directions of arrows O and P, respectively. Therefore, the pair of reel units 5 start rotating in the directions of arrows Q and R (as shown in the 10th figure) via the pair of idler gears 28, respectively. In this way, since the pair of reel units 5 rotate in opposite directions, slack in the magnetic tape within the cassette half 155 is wound up.

When the slack in the magnetic tape is wound up and a predetermined tension is applied to the magnetic tape, all members other than the double gear 5, which is the other component of the reel unit 5 shown in FIG. It is fixed by the reaction force, and only the double gear 5f continues to idle with respect to these fixed members via the felt plate 5h. Therefore, C,
The magnetic tape is not transported with the above tension applied to it.

On the other hand, for example, the end detection gear 14 shown in FIGS. 7 and 18 is rotated by the rotation of the motor 24 in the opposite direction in FIG. 18 via the gear transmission lever 20. . Therefore, the bin 10b protruding from the end detection lever 10 is moved to the top of the 111-shaped projection 141) of the end detection lever 117 as the end detection gear 14 rotates. Here, as is clear from the above, the arms ;)i to each reel unit 1 are stopped. Therefore, the intermediate lever 7 is not activated, and the pin 101 of the end detection lever 10 continues to move along the 111-shaped protrusion 14b. The bottle 10b comes to rest at the top position of the 111-shaped protrusion 171b, and the protrusion 14C of the 1st detection gear 14 engages with the bottle 101). Therefore, the end detection lever 10 moves to the right, and the start trigger lever 73 is rotated in the direction shown in FIG. Riga Lever 7
・When the first gear 33, whose rotation was restricted due to the engagement of the pin 33a with one end of the gear 3, becomes able to rotate, and due to the biasing force of the coil spring 35, the first gear 33 reaches the position shown in FIG. 18. It is rotated in the word direction. Therefore, the partial tooth portion 3311 of the first gear 33 meshes with the gear 16, and the first
The gears begin to turn. As the first gear 33 rotates, the control plate 39 shown in FIG. The head 49 comes into contact with the magnetic tape. Note that the control plate 39 that has reached its maximum forward movement position (leftward movement limit (r7.1fff)
When the engagement recess 69a of the inhibiting lever 69 engages with the inhibiting lever 69, its return movement (movement to the right) is inhibited. 1st
As the gear 33 rotates, the moving member 81 shown in FIG. 17 is also moved to the left as shown in FIG. 23. Therefore, the lever E83 rotates in the direction as shown in FIG. 23, and the movable rod 86a of the electromagnetic solenoid 86, which is already in the on state, is pushed in. By this operation, the pin 830 of the lever E83 comes to engage with the recess 39'h formed at the right end of the control plate 39, and therefore the control plate 39 moves to its most backward movement position (rightward movement limit position). movement becomes possible. Further, by inserting the pin 39e of the control plate 39 into the engagement recess 69a of the prohibition lever 69, the prohibition lever 69 is activated at the time h1 as shown in FIG.
When the upper end of the lever is turned on via the lever J142 (for example, see FIG. 7), the switch 143 is turned on. state.

On the other hand, as shown in FIG. 22, by moving the head stand 47 to the right, it is disengaged from the front idler gear or the double gear 5f of the front reel unit 5, and only the rear reel units i to 5 are rotated. That will happen. Note that this operation is due to the interaction between the protrusion 47a and recess/17b formed on the head stand 47 and the protrusion 56e provided on the slide member 56, but this was explained in detail in the previous explanation of the configuration. It's fast here. Further, as the head stand 47 moves to the right as shown in FIG. is held detached from the corresponding capstan. This is the day 11 section 4A that supports the front pinch roller 90.
This is because the bottle 91a protruding from the pin 91 is fitted into the notch 56C of the slide member 56. As also shown in FIG. 22, by moving the head stand 47 to the right,
The pair of claw members 123 that were engaged with the reel unit 5 are separated from the reel unit.

In this way, tape transport to the FWD side is started, and reproduction on the FWD side is performed.

Next, the operation of switching from FWD-side playback to REV-side playback will be described.

When the switch for switching the tape transport direction is pressed, the electromagnetic solenoid 77 is turned on, and the electromagnetic solenoid is movable.

It will be done. Therefore, the start 1 to trigger levers 73 are rotated clockwise as shown in FIG. 18 via the magnetic head switching command rod 75.
The first gear 33, which had been restricted from rotating, becomes rotatable, and is rotated in the clockwise direction IJ in FIG. 18 by the (I force) of the coil spring 35. The tooth portion 33h meshes with the gear 16,
The first gear starts rotating. When the first gear 33 starts rotating, the protrusion 33 protruding from the first tooth i1 engages with the engagement protrusion 69b of the inhibiting lever 69 (see FIG. 17), and the inhibiting lever 69 (see FIG. Rotate the collar in one direction counterclockwise as shown in Figure 17. Then, the engagement recess 69a of the prohibition lever
The engagement state of the pin 390 of the control plate 39 is released, and the control plate 39 is instantly returned to the most backward movement position (rightward movement limit position td) by the force of the spring 400. By returning the control board 39 to the most backward movement position, the head stand 47 moves to No. 1, h, and the 1° control plate 39, where the air head 49 is 1111111il from the magnetic tape, is at the most (1st movement position). ] When the control plate is at the directional movement limit position), the regulating portion 39 (

The tape transport direction switching operation is almost the same as the above-mentioned "W[] side -) R[V side" except for the point of moving the tape to the V side.
stomach.

Next, the operation of the mechanism that automatically switches the tape transport direction will be explained.

For example, when the tape transport to the FWD side is completed, a predetermined tension is applied to the magnetic tape at the end, and the double gear 5f of the constituent members of the reel unit 1-5 shown in FIG.
All members except for are fixed by the reaction force of the tension. Therefore, only the double gear 5f continues to idle with respect to these fixed members via the felt plate 5h. When the tape is transported to the FWD side, the fixed members are also rotating except for the arm member 51. Further, the arm member 51 receives a biasing force caused by the rotational force (), and forces the intermediate lever 7 via the floating lever 8 in a counterclockwise direction (by 1 in FIG. 22).

As a result, the end detection lever 10, to which the rear end of the intermediate lever is pivoted, is rotated as shown in FIG.

l(7') Rotates while contacting the III-shaped protrusion 1/Ill, and the protrusion 14c of the tart detection 1 and the pin 10b
However, when the end detection lever 10 is engaged, the end detection lever 10 is not engaged. Force f> 10 moves upward, and the star 1-1 ~ 1000 lever 73 rotates in the direction shown in Fig. 18 via the lever ~△12. The tape transport direction is switched from the [-Wl) side to the RIE V side by switching the tape transport direction from the [-Wl) side to the RIE V side.
The automatic switching of the tape transport direction to the WD side is the same as the above operation and will not be described in detail.

Next, F F tlJI work (tape fast forward operation) and R
Next, the FW motion (j-b swallowing motion) will be explained.

Then, switch 1 to mu 1 via lever J142.
43 is turned on. Further, the longitudinal bin 121 protruding from the left end of the head stand 47 is pushed to the left by the tapered portion 113a of the longitudinal operation lever 113, thereby moving the head stand 47 to the left by a predetermined amount, and the magnetic head 49, the contact state of the magnetic tape is loosened.

As is clear from FIG. 25, the backward movement of the longitudinal operating lever 113 causes the protrusion 113C of the longitudinal operating lever to
The lever 1-1126 engaged with the lever 1-1126 is swung counterclockwise in FIG. Therefore, when the lever 1129 is turned as shown in FIG. 25, it swings in the J1 direction, and as a result, the swinging lever 130 rotates counterclockwise in FIG. 26 about the pin 130a as shown in FIG. rotate in the direction. Therefore, the first stage gear 132 of the gear transmission mechanism 135 installed on the swing lever meshes with the gear portion 27a of the rear flywheel 27, and the final stage gear 134
meshes with the small diameter gear portion of the double gear 5r of the 4u 15 reel Ni 1 knit 5. On the other hand, by moving the head stand 47 to the left by pushing the longitudinal operation lever 113, -U
-; The idler gear 28 of iJ is 111111112 from reel 1 [-5. Therefore, the rear tapes 1 to 5 rotate at high speed, and the tape is rapidly forwarded.

When performing the REW movement f1, this is done by pressing the REW movement movement V [lever 11/l]. ,
/1 Straw, I'a Protrusion 114 of the operation lever 114
C engages the second end 126b of the lever 11126 1.
When the lever 11 is turned as shown in Fig. 25, turn it in the R1 direction.
+li-C1-1 first stage gear 132 and final stage gear 137I are in front of people/j's flywheel 27 and -
There is one mesh per luni knit. 4. The movement of the head stand 47 by 1 inch/J is performed by Q, etc., in which the tapered portion 11/IiI of the longitudinal operation lever 114 engages with the longitudinal pin 121 provided on the head stand 47.

-J-When the cassette half is to be adjusted after the 1/1 is completed, the longitudinal operation lever 113 for FF operation and the RF
W operation It is sufficient to press the longitudinal operation lever 114 at the same time.

By simultaneously pressing the two longitudinal operation levers, the intermediate lever 138 (for example, shown in FIG. (6) shown in Figure 6).

Thus, the exact opposite action when loading the cassette half 155 causes the cassette half to be projected into a position for retrieval by the listener. In addition, for example, since the switch 150 shown in FIG. 24 also operates, the electromagnetic solenoid 86 (
(see Fig. 23) is turned off, and the coil spring 8
2, the lever E83 is returned to the state shown in FIG. 17. Therefore, the pin 83 installed (pulled) on the lever E83
C can engage with a convex portion 39o formed on the right end portion of the control plate 39. As a result, the control board 39 is moved to the most backward position (
Returning to the rightward movement limit position) is prohibited.

That is, the state in which the stop pin 34a of the second gear 34 is engaged with the regulating portion 39d of the control plate 39 is maintained, and the second intermediate tooth 34 does not rotate when the power is turned on again. This prevents unnecessary switching of the tape transport direction.

Incidentally, as mentioned above, the operation of the solenoid 860A as described in 1. is also performed after the 4- position of the automobile in which the said bolt is mounted is returned to the A state.

EFFECTS OF THE INVENTION As detailed above, in the cassette 1 to deck C according to the present invention, the cassette 1 to the deck C engages with the cassette half, inserts the cassette half in the direction 3, and becomes the freely movable movable member (top member 99). , a protrusion (99G) facing the reel hole of the cassette 1 to half, and a spring member (99d) that biases the cullet half so that the protrusion protrudes into the reel hole. Therefore, there is no concern that the caret = 7 will jump out of the differential 4 body at the time of adjustment.
The cassettes 1 to 1/2 halves are reliably positioned at the collection position by the listener.

In addition to the protrusion and spring part +4 described above, other parts that engage the cassette 1 to half in the vicinity of the reel hole are also included in the present invention. A protrusion (99e) is installed.

Therefore, the prevention of the cassette half from jumping out from the deck body is 1.
This makes it even more certain.
