Therefore, the protrusion 32a on the bifurcated piece 14b
The auto stop lever 32 that is engaged is given a clockwise rotational force. As a result, the engagement protrusion 32b is brought into a state along the outer peripheral wall of the eccentric gate groove 25a of the first gear 25. Furthermore, when the take-up reel table 10 supplies the tape, that is, rotates in the opposite direction to the arrow, the first arm 14 is given a rotational force in the opposite direction, so the auto stop lever 32 is rotated in the opposite direction. A rotational force is applied, so that the engagement protrusion 32b is in a state along the outer circumferential wall of the cam base 25b. In any of the above cases, when the tape stops running and the take-up roll table 10 stops rotating, the first
Since the arm 14 becomes free, the biasing force applied to the auto-stop lever 32 is also eliminated. Therefore, the first gear 25 rotates and the engagement protrusion 32b moves into the narrowest groove part 25.
After passing through point a, it is located on that trajectory, so it is engaged with the protrusion 25c that is on that trajectory. As a result, after the auto-stop lever 32 is pulled up, the shoulder portion 32c is loosened against the release protrusion 25d of the first gear 25, and the engagement protrusion 3

This corresponds to the cam plate 29c.

Further, a spring 33c is stretched between the other end of the play arm 33 and the chassis 1, and applies a rotational force to the play arm 33 counterclockwise. Therefore, the roller 33a is always supported by the temporary cam 29c. Further, the other end of the play arm 33 corresponds to a control village 2f protruding from the lower surface of the head stand 2. When the cassette 8 is mounted, the cassette stand 2 moves forward for the reasons described above, and the control village 2f comes into contact with the play arm 33 and stops.

This state is the samurai stage state. When a play lever 44, which will be described later, is pressed, the solenoid 31 is energized and the lock arm 30 is attracted. As a result, the engagement between the lock arm 30 and the cam teeth 29b is released, and the cam plate 29c is moved toward the set plate 20 (the first and seventh
, 8) is slightly rotated by the rear end green 20d of the bale (which is pulled downward in Figure 8). As a result, the second gear 2
The active/defective portion 29c of the third gear 29, which was in a position opposite to the third gear 6, is shifted, and therefore the third gear 29 and the second gear 26 are engaged with each other.
The third gear 29 is rotated until the next notch 29a faces the second gear 26. When the gear 29 is rotated, the roller 33a of the play arm 33 is supported by the large flange of the cam plate 29c, so that the play arm 33 is rotated clockwise, and therefore the head stand 2 is further moved forward for playback or playback. This is the recording position. From this state, the stop lever 45
When the solenoid 31 is energized again by pressing , the engagement between the lock arm 30 and the cam teeth 29b is released, and the play arm 33 is now slightly rotated by the roller 33a. As a result, the third gear 29 is engaged with the second gear 26, and the third gear 29 is rotated. Therefore, the roller 33a is connected to the folding portion of the cam plate 29c, and the play arm 33 is rotated counterclockwise to return the head stand 2 to the waiting position. 34 is a fast-forwarding unit supported on the chassis, and the gear 9a of the supply reel stand 9 is placed on the top surface of the unit.

A spring force is always applied to the slide lever 38 toward the front (downward in the figure) by a spring 39. Then, when the fast-forward lever 47 is pushed, the fast-forward arm 35
The hanging piece 35b is the new music part 47c of the fast forward lever 47.
Move forward while in contact with the

As a result, the fast-forward arm 35 comes into contact with the protrusion 34c of the fast-forward unit 34, causing the fast-forward unit 34 to rotate clockwise. Therefore, the rubber roller 34b comes into contact with the first flywheel 4, and the gear 34a is engaged with the gear 10a of the take-up roll stand 10, so that the take-up roll stand rotates at high speed and rapidly feeds the tape. On the other hand, when the rewind lever 48 is pushed, the upright piece 35a of the fast-forward arm 35 moves to the rewind lever 48.
8, and is rotated clockwise against the spring force of the spring 36. As a result, the rapid forwarding unit 34 is rotated counterclockwise by the spring force of the spring 36. Therefore, the rubber roller 34b comes into contact with the second flywheel 6, and the gear 34a is engaged with the gear 9a of the supply reel stand 9, so that the supply reel stand 9 rotates at high speed and rewinds the tape. 40 is a lever arm whose approximately center is supported by a support pin ld of the chassis, one end is supported by a play lever 44 to be described later, and the other end is supported by a set plate 2.

Playing operation First, when the cassette 8 is placed on the head stand 2,
Since the protruding piece 7e of the lock plate 7 is pressed downward, the engagement claw 7d and the lock elongated hole 2e of the head stand 2 are disengaged. Therefore, the head stand 2 has a control village 2f provided on its lower surface.
moves forward until it comes into contact with the play arm 33. In this state, the heads 2a and 2b of the head stand 2 are slightly inserted into the window of the cassette 8. On the other hand, when the head stand 2 moves forward, the protruding piece 3c of the pinch loaf unit 3 is disengaged, so the unit 3 is rotated by the spring 3b and the extension piece 3d comes into contact with the protruding piece 20a of the set plate 20. Unit 3 stops.

At this time, the pinch roller 3a and the capstan 4a are not in contact with each other (FIG. 23). In this state, when the play lever 44 is pushed, the metal 0 parts 44a,' of the lock piece 44a' are engaged with the pot part 76b of the third lock plate 76.

Also. Since the lock piece 44a pushes down the second lock plate 75, the switch S5 located on the lower surface thereof is closed, and the slide lever 77 is further moved by the lock piece 44a to close the switch S3. Therefore, the power switch S,
If the timer switch S2 is closed, the motor 8 is energized. Also, since the switches S4 and S6 are normally in contact, the solenoid 31 is energized.
When the solenoid 31 is energized, the lock arm 30 is attracted and is unlocked from the cam teeth 29b. Then, the cam plate 29c is slightly rotated by the set plate 201, and the third gear 29 is engaged with the second gear 26. Here, since the motor 18 is rotating, the first flywheel 4 is being rotated by the belt 19. Therefore, through the belt 28. - Since the IJ 27 is rotated and the second gear 26 is rotated, the third gear 29 is rotated approximately 180 degrees. Due to the rotation of the third gear 29, the large part of the cam plate 29c comes into contact with the roller 33a of the play arm 33, whereby the play arm 33 is separated from the control village 2f of the rotating head stand 2, and therefore the head stand 2 is moved to the stopper. Further move forward until the elongated hole 2d touches the pin lb. On the other hand, since the supporting front edge 20d of the set plate 20 corresponds to the small diameter portion of the cam plate 29c, it is pulled by the spring 21, so that the extension piece 3d of the pinch roller knit 3 separates from the projecting piece 20a.

As a result, the unit 3 is rotated and the pinch roller 3a
is pressed against the capstan 4a. Further, as the set plate 20 is pulled, the engagement protrusion 17d of the take-up unit 17, which is restricted by the abutting rear end green 2c, moves following the abutting rear edge 20c by the spring 17e.

As a result, the lever 17a is rotated and the rotating shaft 17c is brought into contact with the rubber roller 10b of the winding roll table 10. Therefore, since the take-up pulley 17b is rotated by the belt 19, the take-up reel table 10 is rotated (FIG. 24). As described above, the rotation of the motor 8 rotates the take-up reel table 10 and the capstan 4a, which is the rotating shaft of the first flywheel 4, and the amplifier A operates to reproduce the tape.

When the stop lever 45 is pressed by the play operation, the second lock plate 75 is pushed down by the lock release piece 45a, so the second lock plate 76 is further pushed down, and therefore the lock piece 44a' of the play lever 44 and the third lock plate 75 are pushed down.
The lever arm 4, which will be described later, is removed from the lock plate 76.
01 is returned. Further, the lock release piece 45a of the stop lever 45 closes the switch S8. On the other hand, since the play arm 33 is being rotated, the slide lever 38 that is in contact with it is pushed, opening the switch S6.
Switch S9 is closed. Therefore, the solenoid 31 is energized, the lock arm 30 and the cam teeth 29b are unlocked, the cam plate 29c rotates a little, and the third gear 29 and the second
The gear 26 is engaged with the gear 26. As a result, the third gear 29 rotates approximately 180 degrees, so that the play arm 33 returns to its original position. Therefore, the play arm 33 touches the control village 2f,
Return the head stand 2 to the intermediate position. On the other hand, set plate 2
0 is pulled against the spring force of the spring 21, the supporting rear edge 20c returns the take-up unit 7 to its original state against the spring force of the spring 17e. Therefore, since the rotating shaft 17c separates from the rubber roller 10b of the take-up roll stand 10, the rotation of the take-up roll stand 10 is stopped. Further, when the set plate 20 is pulled, the projecting piece 20a pushes the extension piece 3d of the pinch loaf unit 3, so that the unit 3 is rotated and the pinch roller 3a is separated from the capstan 4a. As described above, the rotation of the winding reel table 10 is stopped and the pinch roller 3a is separated from the capstan 4a, so that the tape stops running.

Furthermore, since the slide lever 77 returns to its original position, the switch S3 is opened, and the power to the motor 18 and amplifier A is also cut off. Next, when the eject lever 60 is pulled, the sub-eject lever 61 is rotated at the same time as the head stand 2 finishes retracting, and the engagement between the metal parts S and b and the engagement punch 64a of the lid body 64 is released. be done.

Therefore, the lid 64 is rotated, and the cassette 8 is released from the head stand 2. Further, as the head stand 2 moves, the engaging claw 7d is pushed down by the back surface of the head stand 2,
Further, when the end face of the lock elongated hole 2e passes through, it faces into the elongated hole 2e, so when the eject lever 60 is released, the engaging claw 7d and the elongated hole 2e are engaged. This ends the project. Recording operation With the cassette 8 loaded in the head stand 2, press the recording lever 5.
When 3 is pressed, the gold phrase part 53a of the lock piece 53a is engaged with the anchor part 74c of the first lock plate 74.

When the recording lever 53 is pressed, the switch S. o is closed and a recording circuit (not shown) is activated. Further, the lock piece 53a of the recording lever 53 moves the slide lever 77, so the switch S3 is closed. Therefore, since the motor 8 operates and the solenoid 31 is energized, the head stand 2 further moves forward by the same operation as in the play state described above, and the set plate 20 retreats, so that the pinch roller 3a is pressed against the cab stun 4a. ,
Further, the rotating shaft 17c is connected to the rubber roller 10 of the winding roll stand 10.
b. Therefore, the tape runs, and recording begins (FIG. 24). Note that the play lever 44 is pulled by the arm lever 40 and engaged with the third lock plate 76. When the fast-forward lever 47 is pushed with the fast-forward operation cassette 8 loaded on the head stand 2, the lock piece 47a is engaged with the pot portion 74b of the first lock plate 74.

Furthermore, when the fast-forwarding lever is pressed, the fast-forwarding arm 35 moves and the hanging piece 35b is in contact with the bending part 47c, so that the fast-forwarding arm 35 moves to the projecting piece 3 of the fast-forwarding unit 34.
Press 4c. As a result, the rapid feed unit 34 rotates, and its gear 34a meshes with the gear 10a of the winding roll stand 10. Further, the rubber roller 34b is pressed against the first flywheel 4. On the other hand, when the fast forward lever 47 is pressed,
Since the lock piece 47a moves the slide lever 77, the switch S3 is closed and the motor is energized. Therefore, the winding reel table 10 rotates at high speed (FIG. 25). Further, when the stop lever 45 is pressed, the second lock plate 75 is lowered, so the first lock plate 74 is also lowered.

As a result, the engagement between the fast-forward lever 47 and the first lock plate 74 is released, and the lever 47 returns to its original state. Accordingly, the fast-forwarding arm 35 returns to its original state, so the fast-forwarding unit 34 also returns, the gears 34a and 10a are disengaged, and the rubber roller 34b is also separated from the first flywheel 4. Further, the slide lever 77 also returns and the switch S3 is opened to enter the stop state. When the rewind lever 48 is pushed with the rewind operation cassette 8 loaded on the head stand 2, the lock piece 48a is engaged with the fishing portion 74b of the first lock plate 74.

Further, when the rewind lever 48 is pushed, the fast forward arm 35 is rotated against the spring force of the spring 36, so the fast forward unit 34 is pulled by the spring force of the spring 37 and rotates, and the gear 34a and the Gear 9 of reel stand 9
a are meshed with each other. Further, the rubber roller 34b is pressed against the second flywheel 6. On the other hand, when the rewind lever 48 is pushed, the lock piece 48a moves the slide lever 77, so the switch S3 is closed and the motor 18 is energized. Therefore, the supply reel stand 9 is rotated in reverse at the rotational speed (FIG. 26). Further, when the stop lever 45 is pushed, the second lock plate 75 is lowered, and the first lock plate 74 is also lowered.

This releases the engagement between the rewind lever 48 and the first lock plate 74, and the lever 48 returns to its original state. Therefore, due to the spring force of the spring 36, the rapid forwarding arm 35 also returns to the original state of the rapid forwarding unit 34. As a result, the gear 34a and the gear 9a are disengaged, and the rubber roller 34b is also separated from the second flywheel 6. Further, the slide lever 77 also returns and the switch S3 is opened to enter the stop state. Auto stop operation during play or recording operation As mentioned above, during play or recording operation, the head stand 2 moves forward to the green position, and the winding reel stand 1 moves forward to the green position.
0 is rotating, rotational force is applied to the first and second end detection arms 4 and 15 in the same rotational direction as the winding roll table 10.

Therefore, the auto-stop lever 32 engaged with the first arm 14 is also given a rotational force in the same direction, and the engagement protrusion 32b provided at the tip of the auto-stop lever 32 engages with the eccentric circular groove 25a of the first gear 25.
is pressed against the outer peripheral wall of the On the other hand, the first gear 25 is engaged with the second gear 26, and since the belt 28 is wound between the second gear 26 and the first flywheel 4, the first gear 25 is rotating. Therefore, the first gear 25 is rotated with the engagement protrusion 32b pressed against the outer peripheral wall, and the engagement protrusion 32b and the protrusion 25c are not engaged. When all of the tape is wound up and the rotation of the winding reel stand 10 stops, the external force that was pressing the engagement protrusion 32b against the outer circumferential wall disappears, so that the engagement protrusion 32b is pushed into the narrowest groove 2.
5a, it is held at that trajectory position. Since the protrusion 25c is located on this trajectory, the rotation of the first gear 25 causes it to engage with the engagement protrusion 32b. This causes the auto-stop lever 32 to be pulled and the stop lever 45 to be pulled. Pulling the stop lever 35 is the same as pushing the stop lever 35. Therefore, the above-mentioned play state is changed to the stop state by an action similar to the stop action.
2b and the protrusion 25c are engaged, as the first gear 25 rotates, the shoulder portion 32c of the auto stop lever 32 comes into contact with the release protrusion 25d of the first gear 25, and the engagement protrusion 32
b and the protrusion 25c are disengaged, and the stop lever 45 returns to its original position. Auto-stop operation during fast forwarding As described above, during fast forwarding, the head stand 2 is in the intermediate position, and the take-up IJ-roll stand 10 is rotating at high speed in the same direction as in the play state.

Therefore, the engaging protrusion 32b is connected to the eccentric circular groove 25a of the first gear 25.
is pressed against the outer peripheral wall of the Then, when the rotation of the winding reel stand 10 stops, the engaging protrusion 32b and the protrusion 25c are engaged by the same operation as described above, and the following operation is the same as that during play and recording, so a description thereof will be omitted. .
Note that even if the stop lever 45 is pulled and the switch S8 is closed, the head stand 2 is in the intermediate position, so the switch S9 is closed.
remains open and solenoid 31 is not energized.

Auto-stop operation during rewinding As described above, during rewinding, the head stand 2 is in the intermediate position, and the winding reel stand 1 is rotating at high speed in the opposite direction to the play state.

Therefore, since the auto-stop lever 45 is given a rotational force in the opposite direction to that in the above case, the engagement protrusion 32b is pressed against the cam base 25b in the eccentric circular groove 25a of the first gear 25. As a result, while the take-up reel stand 10 is rotating, the first gear 25 is rotated with the engagement protrusion 32b in pressure contact with the cam stand 25b. Then, when the rotation of the winding reel stand 10 stops, the engagement protrusion 32b is moved to the narrowest twill portion 25a,
After passing through, it is held at that trajectory position. Since the protrusion 25c is located on this trajectory, the rotation of the first gear 25 causes it to engage with the engagement protrusion 32b. Since the following operation is exactly the same as the auto-stop operation during fast forwarding, the explanation will be omitted. Pause operation during play and recording As described above, during play and recording, the head stand 2 is in the mirror position and the winding reel stand 10 is rotating.

When the pause lever 42 is pressed here, it is locked by the lock plate 43 and the set plate 20 is pushed, causing the take-up unit 17 to rotate. As a result, the rotating shaft 17c separates from the rubber roller 10b of the take-up roll stand 10, and the rotation of the take-up roll stand 10 is stopped. That is, the state is the same as when the tape has stopped running in the play and record states described above, but here, the biasing arm 22 is rotated by the spring force of the spring 23, and the control lever 2 is rotated.
Rotate 4. Therefore, the toe stop lever 32 that is in contact with the control lever 24 is rotated in the same direction as in the play or fast forward state, and the engaging protrusion 32b is moved into the eccentric circular groove 25a.
The twill can be applied to the outer peripheral wall of the area. As a result, while the first gear 25 is rotating, the engagement protrusion 35b and the protrusion 25c are not engaged, that is, the playing or recording state is not stopped (FIG. 27). Auto-stop operation during fast forwarding or rewinding During fast forwarding or rewinding, the head stand 2 is in an intermediate position and the winding reel stand 10 is rotating at high speed.

Even if the pause lever 42 is pressed here, since the large part of the cam plate 29 is in contact with the set plate 20 and the biasing lever 22, both levers 20 and 22 will not be affected in any way, so the biasing lever 22 will not be affected in any way. No external force is applied to the auto-stop lever 32. That is, the auto-stop operation is performed by an operation similar to the above-mentioned auto-stop operation after the tape is wound or rewound. When the fast forward lever 47 is pressed in the cue operation play state, the fast forward unit 34 is rotated via the fast forward arm 35 to engage the gear 34a with the winding IJ roll table 10 and the gear 10a,
Also, the rubber roller 34b is brought into pressure contact with the first flywheel 4.

When the fast forward lever 47 is pressed, the switch S9 is closed via the slide lever 38, and the switches S, . is closed, so the solenoid 31 is energized. As a result, the cam plate 29c rotates, the arm lever 33 is rotated, the head stand 2 is returned to the intermediate position, the pinch roller 3a is separated from the capstan 4a, and the rotating shaft 17c is moved away from the rubber roller 10a of the winding reel stand 10. Leave. Therefore, the winding reel table 10 is rotated at high speed and enters a fast forwarding state. Also, even if the first lock plate 74 is lowered, the third lock plate 74
Since the lock plate 76 does not descend, the play lever 44 remains locked to the third lock plate 76. Note that since the set plate 20 does not allow the lever arm to be rotated by four degrees, the play lever 44 is not returned. When you release your hand from the fast-forward bar 47, the fast-forward arm 35 returns, the fast-forward unit 34 also returns, and the gear 34
a is disengaged from the gear 10a of the take-up reel table 10, and the rubber roller 34b is separated from the first flywheel 4, and the fast-forwarding state is released.

Also, as the table feed lever 47 returns, the slide lever 38 and the auxiliary lever 49 return, so the switches S6 and S
4 is closed (the switch S3 is closed because the second lock plate 75 is lowered, and the switch S3 is closed because the second lock plate 75 is lowered).
is moving (closed), so the solenoid 31 is energized. As a result, the cam plate 29c rotates, the arm lever 33 is rotated, the head stand 2 is returned to the green position, the set plate 20 is moved, the pinch roller 3a is pressed against the capstan 4a, and the rotating shaft 17c is rotated. The bale falls on the rubber roller 10a of the reel stand 10. Therefore, it returns to the pre-state again. When the rewind lever 48 is pressed in the review operation play state, the fast forward arm 35 is rotated and pulls the fast forward unit 34 via the spring 37, but at this time the protrusion 34d of the fast forward unit 34 touches the step 38c of the slide lever 38. Since it is a donation, the gear 34a and the gear 9a of the donation reel stand 9 are not engaged.

That is, the tape is prevented from being pulled in the opposite direction before the playing state is released. Since the rewind lever 48 is pressed, the switch S is moved by the auxiliary lever 49.
、． is closed (switch S9 is closed by the slide lever 38), so the solenoid 31 is energized. As a result, the head stand 2 returns to the intermediate position in the same manner as the cue operation described above, the pinch roller 3a separates from the capstan 4a, and the rotating shaft 17c separates from the rubber roller 10a of the winding reel stand 10. Also, when the play arm 33 is rotated, the protrusion 34 of the fast-forwarding unit 34 is rotated.
d and the stepped portion 38c of the slide lever 38 are disengaged. The rapid feed unit 34 further rotates, and the gear 34a and the gear 9a of the supply reel stand 9 are engaged with each other, and the rubber roller 3
4b is brought into pressure contact with the second flywheel 6 and enters a rewinding state. When the rewind lever 48 is released, the fast-forward arm 35 and the fast-forward unit 34 return to their original states, the gear 34a and the gear 9a of the supply reel stand 9 are disengaged, and the rubber roller 34b is moved to the second flywheel. 6, the rewinding state is released. Thereafter, the player returns to the playing state again by the same operation as the cue operation. When the rewind lever 48 is pressed in the quick review recording state, the first lock plate 74 is lowered by the lock piece 48a, so that the recording lever 53 and the first lock plate 74 are disengaged and the recording circuit is stopped.

However, the play lever 44 is held in a locked state as in the cue and review operations described above. Note that the second lock plate 75 of the rewind lever 48 is connected to the play lever 44.
By being lowered by the lock piece 48a, the lock piece 48a
and the first lock plate 74 are never engaged. Furthermore, in the cue and review operations described above, the fast forward lever 47 and the rewind lever 48 are not engaged with the first lock plate 74, respectively, for the same reason as described above. Then, when the rewind lever 48 is pressed, the rewind state is entered by an operation similar to the review action described above, and when the rewind lever 48 is released, the play state is entered.

Therefore, the recorded portion can be edited by simply operating the rewind lever 48.
It is something that can be played. Auto repeat operation If the auto repeat lever 66 is locked when neither recording nor fast forwarding or rewinding is being performed, switch S7
is closed, so the motor 18 operates.

Also, the beat slide lever 69 is moved forward by the auto repeat lever 66, and the engagement piece 69d provided on the lever 69 pushes the upright piece 35a of the fast forward lever 35.
The fast-forwarding lever 35 is rotated to rotate the fast-forwarding unit 34 via the spring 37. Therefore, gear 34a
is engaged with the gear 9a of the supply reel stand 9, and the rubber roller 34b is pressed against the second flywheel 6, resulting in a rewinding state. When all of the tape has been rewound and the rotation of the winding reel stand 10 has stopped, it is stopped by the auto-stop operation described above and the bar 45 is pulled. Since the switch S7 is closed and the head stand 2 is in the intermediate position, the switches S4 and S6 are closed, and the stop lever 45 is pulled and the second lock plate 75 is lowered, so that the switch S5 is closed. is open, so the solenoid 31 is energized. Therefore, the play arm 33 is rotated, the head stand 2 is moved forward to the new position, and the set plate 20 is moved forward, so that the pinch roller 3a and the capstan 4a are heated, and the rotating shaft 17c and the winding The rubber roller 10a of the reel stand 10 is brought into contact with the rubber roller 10a. Furthermore, since the slide lever 38 is advanced by the rotation of the play arm 33, the stepped portion 38c is aligned with the protrusion 34 of the fast-forwarding unit 34.
Press d, rotate the table feeding unit 34 a little, and move the gear 3.
4a and the gear 9a of the supply reel stand 9 and release the rubber. - Separate the roller 34b and the second flywheel 6. Therefore, it becomes a play state. When the set plate 20 moves forward, the bar arm 40 is rotated, and the play lever 44 is therefore pulled and locked by the third locking plate 76, so that it can be seen from the outside that the play operation is in progress. When the play operation is completed and the rotation of the take-up reel table 10 is stopped, the above-mentioned auto-stop operation is activated and the play arm 33 is rolled.

As a result, the slide lever 38 moves forward, and the stepped portion 38c
is disengaged from the protrusion 34d of the fast-forwarding unit 34, and the fast-forwarding unit 34 is rotated so that the gear 34a and the gear ga of the supply reel stand 9 are engaged with each other, and the rubber roller 3
4b and the second flywheel 6 are compressed and put into an unwound state. Similarly to the above-mentioned operation, when the rewinding is completed, the play operation is started and becomes an auto-repeat operation. Auto-repeat operation during recording operation When the auto-repeat lever 66 is locked during the recording operation, the recording operation is performed without being rewound by the same operation as during the play operation described above.

When the recording is completed and the rotation of the winding reel stand 10 is stopped, an auto-stop operation is performed, the recording lever 53 is released, and a rewinding operation is started. After rewinding is performed by an operation similar to the auto-repeat operation in the entrusted play operation, the play state is entered. Manual auto repeat operation If a play operation is performed with the auto repeat operation and the bar 66 locked, the auto stop operation will operate at the end of the play operation and rewind will be performed. If you want to return it, press the stop lever 45.

When the lever 45 is pressed, the switch S8 is closed (the switch S7 is closed because the auto repeat lever 66 is locked, and the switch S9 is closed because the play arm 33 is rotated clockwise and the slide lever 38 is moved forward). (closed), so the solenoid 31 is energized. Therefore, the play arm 33 is laid down, the head stand 2 is moved back to the intermediate position, and the set plate 20 is moved forward, so that the pinch roller 3a and the rotating shaft 17c are separated from the stand 4a and the take-up roll stand 10, respectively. Further, the rotation of the play arm 33 causes the slide lever 38 to move backward, causing the fast-forwarding unit 3
4 is released, the fast-forwarding unit 34 rotates, the gear 34a meshes with the gear of the supply reel stand 9, and the rubber roller 34b is pressed against the second flywheel 6. Therefore, it becomes a rewinding state. To change the play state from the rewind state, press the stop lever 45 again to close the switch, and since the head stand 2 is in the intermediate position, switches S4 and S6 are closed, and the auto repeat lever 66 is closed. Since the switch S7 is closed due to the locked state, the solenoid 31 is energized. Since the following operation is the same as the operation from the rewinding state of the auto-repeat operation described above to the play state when the auto-stop is activated, a description thereof will be omitted. Fast-forward operation in auto-repeat operation When the fast-forward lever 47 is pressed to perform a fast-forward operation during a play operation with the auto-repeat lever 66 locked, the lock piece 47a moves against the first lock plate 74.
is engaged with the hook portion 74b of.

Also, as the fast forwarding lever 47 moves forward, the slide lever 38
moves forward, switch S9 is closed, and auxiliary lever 49
also move forward and switch S, . is closed, so the solenoid 31 is energized. Therefore, the head stand 2 is moved back to the intermediate position by the same operation as when the stop lever 45 is pressed during the play operation in the auto-repeat operation described above.
The pinch roller 3a is connected to the rotating shaft 17 from the capstan 4a.
c are separated from the winding reel stand 10, respectively. Since the fast-forwarding lever 47 is pressed, the fast-forwarding arm 35 moves and pushes the protrusion 34c of the fast-forwarding unit 34 to rotate the fast-forwarding unit 34. Therefore, the gear 34a is engaged with the gear 10a of the winding roll table 10, and the rubber roller 3
4b is brought into pressure contact with the first flywheel 4, resulting in a fast-forwarding state. When the stop lever 45 is pressed in this fast-forwarding machine, the play operation is shifted to by an operation similar to the operation from rewind to play in the manual repeat operation described above. Song interval detection operation When the song interval detection lever 56 is rotated, the lower tip 56b rotates the control plate 59 counterclockwise against the spring force of the coil spring 60.

At the same time, since the protrusion 56a of the lock plate 57 moves, a clockwise rotational force is applied by the spring force of the coiled spring 58. Therefore, the pawl 57a of the lock plate 57 is initially
9, but as the control plate 59 rotates, the claw 5
Since one end of the control plate 59 is located above the lock plate 7a, the claw 57a of the lock plate 57 and the control plate 59 are engaged and locked by the spring force of the coiled spring 58. Also, the song interval detection lever 5
6 turns the switch Ps ON. Next, when the play lever 44 is operated, the tape enters a playback state and starts running. At this time, since the third lock plate is pushed down by the control plate 59, the play lever 44 is not locked and is held in the operating state only by the lever arms 4. For example, when the rewind lever 48 is operated in this playback state, the lever 48 is locked to the tenth hook plate 74 and the playback state is shifted to the rewind state. Since the song interval detection lever 56 and the rewind lever 48 are operating, the song interval detection circuit MS is activated and the song interval (no signal period) on the tape is activated.
When this is detected, the play lever 44 is pulled in from the lever arm 4, lifts the second lock plate 75, releases the rewind lever 48 locked to the first lock plate 74, shifts to the playback state, and starts the desired recording. Play part. Rapid forwarding can also be performed in the same manner. Close the recording timer operation power switch S, and lock the recording lever 53. In this state, when the timer switch S2 is closed, the slide lever 77 has moved, so the switch S3 is opened, and the recording lever 53 has moved, so the switch S3 is opened.
. is closed, and since the head stand 2 is in the intermediate position, the switches S4 and S6 are closed. Therefore, recording is started by an operation similar to the recording operation described above, and is brought to a stop state by an auto-stop operation when the tape ends. Close the play timer operation power switch S, and lock the play lever 44.

When the timer switch S2 is closed in this state, the slide lever 77 has moved, so the switch S3
is closed, the play lever 44 is pushed again, and the second lock plate 75 is closed.
is descending, the switch is closed, and the head stand 2 is closed.
Since is in the intermediate position, switches S4 and S6 are closed. Therefore, the play starts with the same operation as the play operation described above, and when the tape ends, the automatic stop operation brings about a stop state. Remote Control Operation Mechanism When a remote control switch S, 2 provided at a location not shown in the drawings is pressed, the motor 18 is energized, the second gear 27 is rotated, and the first gear 25 is rotated.

However, since it is not in the recording/reproducing state or in the fast forwarding or rewinding state, the supply reel stand 9 and the take-up reel stand 10 do not rotate either, and the auto-stop operation is activated. To operate the remote control, first lock the song interval detection lever 56 and press the third lock plate 7.
6 is lowered. Then, when the stop lever 45 is pulled by the auto-stop operation and the switch S5 is closed (at this time, since the head stand 2 is in the intermediate position, the switches S4 and S6 are also closed),
Solenoid 31 is energized. Therefore, play arm 33
rotates, the head stand 2 moves forward to the recording/playback position, the set plate 20 is pulled forward, the pinch roller 3a is pressed against the capstan 4a, and the rotating shaft 17c moves forward to the winding reel stand 10.
The rubber roller 100 is covered with the rubber roller 100. Therefore, the play state is reached, and the play lever 44 is activated by the lever arm 40.
is drawn. However, since the third lock plate 76 is lowered by the time-song interval detection lever 56. hook piece 44
and the third lock plate 76 are not engaged. Therefore, the play lever 44 is maintained in the pulled state only by the arm lever 40'. Then, when the remote control switches S, 3 are closed, even if the remote control switches S, 2 are opened, the play state is reached, so S3 is closed. Therefore, the solenoid 31 is energized, so the head stand 2 returns to the intermediate position, the pinch roller 3a is separated from the capstan 4a, and the rotating shaft 17c is made of rubber. away from the controller 10b. Furthermore, the arm lever 40 returns the play lever 44 to its original state. And again the remote control switch S. When 2 is closed, the above-described operation returns to the playing state. Memory operating mechanism Memory switch S. not shown in the drawing. Press 4.

Then set counter 1 to zero and turn play lever 4.
When 4 is locked, the above-mentioned action becomes a play action. If it is desired to open the playback section again, the stop lever 45 is operated to perform the above-described stop operation to bring the playback to a stop state. Next, the rewind lever 48 is locked and the tape is rewound by the above-described rewind operation. When the counter 1 is reversed and reaches 999, the counter switch S, 5 is closed, and the slide lever 7 is closed.
7 has moved and the switch S3 is closed, and the head stand 2 is in the intermediate position and the switch S6 is closed, the solenoid 31 is energized. As a result, the play arm 33 is rotated and the head stand 2 is advanced to the sickle repositioning position.
In addition, by moving the set plate 20 toward the front, the pinch roller 3a is brought into contact with the capstan 4a, and the rotating shaft 17c is brought into contact with the rubber roller 10b of the winding reel stand 10. Therefore, the play state is entered, and the play lever 44 is moved forward by the bar arm 4 and locked.
Note that the rewind lever 48 is unlocked. Also, if you lock the auto repeat lever 66 during playback,
As explained in the auto-repeat operation, when it is detected that the rotation of the winding reel table 10 has stopped after the tape has been reproduced, the rewinding operation state is entered.

When the rewinding progresses and the counter 11 reaches 999, the counter switches S and 5 are closed, as explained in the above-mentioned memory operation, and the playback state resumes. That is, the same portion can be opened by alternately reproducing and rewinding from the tape position where the counter 1'1 is reset to the end of the tape. Second Memory Operation This operation is performed when it is desired to use the two counters 11 and 79 to reproduce a desired portion in the middle, rather than between the middle and end of the tape.

In the playback state, if you want to listen to the playback part again, reset the counter 1 that is being added at that time.
Press 1c to reset.

Then, as the playback progresses and the end of the part you want to hear again is reached, the reset button 79c of the subtracting auxiliary counter 79 is pressed to reset it. Since this auxiliary counter 79 has been decremented, the red display is immediately performed and the switches S and 6 of the auxiliary counter 79 are closed. In this state, operate the memory switch S, 4 (not shown), and then operate the rewind lever 48.
When locked, the slide lever 77 moves and the switch S3 is closed. Also, since it is in the play state at this time, the switch S9 is also closed, so the solenoid 31
is energized, the play arm 33 is rotated, the head stand 2 is returned to the intermediate position, and the pinch low unit 3 is retreated, resulting in a stopped state. Further, as the play arm 33 is rotated, the regulating force of the fast forwarding unit 34 is released, and the gear 34a is engaged with the gear 19 of the supply reel stand 9, thereby rewinding the tape. When the counter 11 is reversed and reaches 999, the switches S and 5 are closed, and the playback is switched to playback by the memory operation described below. As this regeneration progresses and the red display 79d appears past the position where the auxiliary counter 79 was reset, the switches S and 6
is closed.

At this time, the switch S3 is closed by the slide lever 77.
Since the switch S9 is closed depending on the regeneration state, the solenoid 31 is energized. Thereafter, the stop state is achieved by the same operation as after the energization of the solenoid 31 described in the above-described play operation to stop operation. In this state, the red display 79d of the gear 79b of the auxiliary counter 79 is displayed, thus indicating the end of the memory operation. Next, when the above-described auxiliary counter 79 is reset and the memory switches S and 4 are closed, the auto-repeat lever 66 is locked, and the switch S7 is closed. Since S9 is closed, the solenoid 31 is energized.

Therefore, the play arm 33 is rotated and the head stand 2 is returned to the intermediate position, and the pinch roll unit 3 is moved backward, resulting in a stopped state. Further, the auto repeat lever 66 moves the repeat slide lever 69 forward, and the lever 6
Since the engagement piece 69d provided at 9 pushes the upright piece 35a of the fast-forward lever 35, the fast-forward lever 35 is rotated and the fast-forward unit 34 is rotated via the spring 37. Therefore, the gear 34a is engaged with the gear 9a of the supply reel stand 9, and the rubber roller 34b is pressed against the second flywheel 6, resulting in a rewinding state. Simultaneously with this rewinding, the counter 11 is decremented, and when the value reaches 999, the switch S, 5 of the counter 11 is closed. Here, the memory switches S, 4 are closed, and since the switch S6 is not in the regeneration state, the switch S6 is also closed, so that the solenoid 31 is energized. The regeneration state is switched to the regeneration state by the same operation as after energization of the solenoid 31 described below in the auto-repeat operation. Then, as the reproducing operation progresses and the red display 79d appears past the position where the auxiliary counter 79 was reset, the switches S and 5 of the auxiliary counter 79 are closed.

At this time, the switch S9 is closed since regeneration is in progress, and therefore the solenoid 31 is energized. Thereafter, the above-mentioned operation is repeated, rewinding is performed again, and the counter 11 is
When the number reaches 999, playback is performed again, which is repeated. In the above, in order to stop the auto-repeat operation, if the auto-repeat lever 66 is unlocked, the stop operation will be performed at the point where the auxiliary counter 79 is reset as described above.

Eject operation while the winding reel table is rotating When the eject lever 60 is operated while the winding reel table 10 is rotating by the driving force of the motor, that is, during recording, playback, or fast-forwarding operations, the head table 2 moves to the final position. As it moves backward, the cassette 8 is ejected from the reel stands 9 and 10.

However, in this state, the winding reel stand 10 continues to rotate due to the driving force of the motor, so the device continues to operate.
Therefore, as shown in FIGS. 16 to 18, the eject lever 60 is
When is operated, the pick-up station 10 is forcibly stopped, and the apparatus is stopped by the auto-stop operation described above. That is, in the embodiment shown in FIG. 16, the winding reel stand 10 is stopped by the return of the pinch loaf unit 3, in FIG. 17 by the retraction of the head stand 2, and in FIG. 18 by the ejection of the cassette 8. . Remote control operation in auto-repeat operation The remote-control operation does not operate unless the song interval detection lever 56 is locked as mentioned above, but the case where the auto-repeat lever 66 is also locked will be explained here.

In this case, as can be seen from the circuit diagram in FIG. 22, the remote control switches S, 3 are connected in parallel with the circuits of switches S4, M, S6, and the circuits of switches S8, S9, respectively. Short to operate the solenoid 3
1 can be energized.

Therefore, the above manual repeat operation can be performed remotely. As described above, this invention uses two counters: a counter that is added as the reel stand rotates, and an auxiliary counter that is subtracted. When the counter switch is closed, the tape is switched to the playback state, and when the tape is played back, the tape is played back to the point where the counter is set to 1', and when the auxiliary counter switch is closed, the tape is switched to the rewind state. It is possible to repeatedly play from the point at which the counter is reset to the point at which the auxiliary counter is reset, thus enabling auto-repeat of a desired part in the middle of the tape, and the auxiliary counter turns red at the time of reset and at the end of playback of the repeat operation. etc., so that it is easy to confirm whether the operation is a one-side repeat operation or a repeat operation of an arbitrary section, etc., and it also has the effect that it is possible to know the end position of the repeat operation at a glance. .
