When one or more of the search levers 4, 6, 8, and 12 are locked to the lock lever 13, when the first stop lever 2 is operated, the lock levers 13 are all unlocked and the device is in a stopped state. In addition, when the second high-speed feed release lever 10 is operated, all of the operating levers that are locked to the lock lever 13, except for the playback lever 4, are unlocked by the lock lever 13. The configuration is as follows. Reference numeral 16 designates a lock lever release lever A, which is rotatably inserted into a rotating shaft 10 provided on the main board within a predetermined range, and is prevented from coming off by a stopper 17.

A portion 16a of the lock release lever Al6 is arranged so as to come into contact with a protrusion 131 provided on the lock lever 13 as the lever 16 rotates in the direction of arrow W, thereby rotating the lock lever 13 in the direction of arrow C. Further, the lever 18 is rotatably attached to a rotation fulcrum shaft 16b provided on the lever 16, and the lock release lever B is prevented from coming off by a stop 20 together with a spring 19.
It is biased in the direction of arrow S by a spring 19 hooked on a spring hook 16c provided on the lever 16 and also serving as a stopper, but a lever 24 (described later) interlocking with the levers 8 and 12 moves the lever 16 as shown in FIG. Waiting state. This lever 1
The part 18b of the lock lever 13 comes into contact with the protruding part 13k of the lock lever 13 as the lever 16 rotates as necessary, and the part 18b of the lever 1
3 is arranged to move (in the direction of arrow B). Reference numeral 21 is an electromagnetic solenoid fixed on the main board 1.

Reference numeral 22 denotes the iron core of the electromagnetic solenoid 21, which can move in the directions of arrows U and V, and a pin 22a is inserted into the vicinity of its tip, and the pin 22a is connected to the notch provided in the lock release lever Al6 mentioned above. 16d so as to be rotatable and slidable, and are configured to be mechanically interlocked.

Reference numeral 23 is a spring having one end in contact with the solenoid 21 and the other end in contact with the pin 22a, and is configured to constantly urge the iron cores 22 and 22a in the direction of the arrow V, and in conjunction with this, the lever 16 also moves in the direction of the arrow W. It is configured to be biased in the opposite direction.

Further, the lever 4 is configured to slide in the directions of arrows Q and R by a guide (not shown), and is normally biased in the direction of arrow R by the biasing force of a spring (not shown) to a predetermined position (
The lever 4 is on standby at the position shown in FIG. It is arranged to slide in the R direction. Next, each operation of the tape recorder according to the embodiment of the present invention will be explained.

In FIG. 1, each operating lever 2, 4, 6, 8, 10
, 12 are all springs 3, 5, 7, 9, 11, 1
3 and is at the stop position. Now, if you press the regeneration lever 4 in the direction of arrow G against the elastic force of the spring 5,
When the lock pin 4b fixed to the lever 4 also advances in that direction and is further pressed after contacting the corresponding slope portion 13d of the lock lever 13, the lock lever 13 is moved by the spring 1 in the direction of arrow A.
5 in the direction of arrow B (up to the double-dashed line)
be moved.

When the regeneration lever 4 is pushed and moved by a predetermined distance, the lock pin 4 crosses the top of the sloped portion 13d of the lock lever 13, and
As a result, the lock lever 13 no longer receives the pressing force from the lock pin 4b, returns to the direction of arrow A due to the urging force of the spring 15, and the lock pin 4b of the regeneration lever 4 engages with the engaging portion 13e of the lock lever 13. Then, as shown in FIG. 4, the playback lever 4 is latched and locked by the lock lever 13, and a mechanism (not shown) associated with the playback lever 4 puts the tape recorder into the playback state. Here, to explain in more detail the lock pin 4b and the engaging portion 13e of the lock lever 13, the lock lever 13 operates in two directions, rotation and sliding, so the lock pin 4b of the regeneration lever 4 corresponds to the lock pin 4b. The position of the engaging part 13e of the lever 13 is such that after it is engaged with the engaging part 13e of the lock pin 13, it does not interfere with the engagement of other operating levers that are simultaneously engaged, that is, the position of the lock pin 4b. is the engaging portion 13e of the lock lever 13
It is desirable that the lock lever 13 be in a position where it can easily rotate in the directions of arrows C and D in FIG. 2 when the lock lever 13 is locked. Therefore, in this embodiment, even if the lock pin 4b of the regeneration lever 4 is engaged with the engaging portion 13e of the lock lever 13 and the lock lever 13 rotates around the rotation center shaft portions 13a and 13b, the regeneration lever will not move. A position where the absolute position of the engaging portion 13e of the lock lever 13 corresponding to the lock pin 4b does not change much, that is, the rotation center axis 13a, 1 of the lock lever 13.
The engaging portion (13e) is selected at a position close to the rotational axis connecting the parts 3b. FIG. 4 is a plan view of the main parts of the tape recorder according to this embodiment when the tape recorder is in the reproduction state as described above.

If the tape recorder is to be stopped manually, the stop lever 2 shown in the figure may be pressed (in the direction of arrow E). That is, when the stop lever 2 is pressed against the urging force of the spring 3 in the direction of the arrow F, the lever 2 advances in the direction of the arrow E, and the release pin 2b provided on the lever 2 also advances as the lever is pressed. , the release pin 2b is connected to the slope portion 13c provided on the lock lever 13.
After contacting the lock lever 13, the lock lever 13 is moved in the direction of arrow B against the biasing force of the spring 5 in the direction of arrow A. Then, the stop lever 2 is pressed a predetermined distance, the stop lever 2 and the lock lever 13 are moved to the positions shown by the dashed lines in FIG. 4, and the lock pin 4b fixed to the regeneration lever 4 is locked. The engagement portion 13e of the lever 13 is released, and the regeneration lever 4 returns to its original position (the position shown in FIG. 1) by the biasing force of the spring 5 in the direction of arrow F. Next, when the tape end of the magnetic tape is detected in the playback state shown in FIG. It is attracted in the direction of arrow U against the force, and as a result,
Since the pin 22a fixed to the iron core 22 also moves in the direction of arrow U, the pin 22a can be freely rotated in the notch.
In addition, the slidably inserted lock release lever Al6 rotates in the direction of arrow W as the iron core 22 is attracted around the fulcrum shaft 10 provided on the main board. On the other hand, the lock release lever Bl8, which is attached to the fulcrum shaft 6b provided on the lock release lever Al6 so as to be able to rotate within a predetermined range, is supported by a spring 1.
Although it receives a force trying to rotate in the direction of arrow S due to the biasing force of 9, the lock release lever Bl8 is structured so that it comes into contact with the end of the lever 24 and is prevented from rotating. It rotates almost in unison with the rotation. And Rotsukreba. - Projection part 1 provided in 13
3k, part 18b (shaded part) of lock release lever Bl8
If the lock release lever Al6 and the lock release lever Bl8 are rotated in the same direction, the lock lever 13 will be biased by the biasing force of the spring 5 in the direction of arrow 1A due to the above-described operation. The tape recorder is moved in the direction of arrow B against the above-mentioned manual stop, and the playback lever 4 is released from the lock by the lock lever 13, and the tape recorder returns from the playback state to the original state, that is, the stop state. . At this time, the electromagnetic solenoid 2-1 is de-energized and the iron core 22
and the associated lever 16 is returned by the spring 23. However, when the electromagnetic solenoid 21 is energized from the state shown in FIG. First, the part 16a of the lock lever 13 is rotated so that the protrusion 13j of the lock lever 13 is rotated.
2, the lock lever 13 is rotated by a predetermined angle in the direction of arrow C in FIG. ) Next, a case will be described in which the tape recorder l is set to fast-forward the magnetic tape from the stopped state shown in FIG.

In Fig. 1, when the fast-forward operation lever 8 is pressed, the spring 9
The lever 8 moves forward in the direction of arrow K against the biasing force in the direction of arrow L. When the fast-forward operation lever 8 moves forward to a certain position, the head of the lock pin 8b provided on the lever 8 is moved to the protruding slope portion 1 of the lock lever 13.
3g, and then moves forward, the lock pin 8b of the fast-forward operation lever 8 tries to push away the lock lever 13 in the direction of arrow C through its protruding slope 13g. is its rotating shaft 13a,
13b as a center, it is rotated by a predetermined angle in the direction of arrow C against the biasing force of the spring 4 in the direction of arrow D. On the other hand, when the fast-forward operation lever 8 is pressed and moved to a predetermined position, the lock pin 8b is moved to the protruding slope portion 13 of the lock lever 13.
In order to overcome the contact with g and overcome it, the lock lever 13 is again rotated back to its original state by the biasing force of the spring 4 in the direction of the arrow D. After this, even if the pressing force of the fast-forward operation lever 8 is released, the lock pin 8b of the lever 8
Since the lever 8 is locked by the locking protrusion 13m of the lock lever 13, the lever 8 does not return to its original position and is in the state shown in FIG. In this state, a mechanism (not shown) linked to the operation of the fast-forward operation lever 8 causes the tape recorder to enter the fast-forward state. At this time, in FIG. 5, the lever is interlocked with the fast-forward operation lever 8 as described above, so it stands by in a moved state as shown in the figure. To stop the tape recorder from the fast-forward state shown in FIG. 5, the stop lever 2 can be pressed. The lock lever 13 is activated by pressing the stop lever 2 in the same way as when pressing the stop lever 2 from the above-mentioned playback state (FIG. 4).
moves in the direction of arrow B in the figure, and the lock pin 8b of the fast-forwarding lever 8 moves toward the lock lever 1 as shown by the two-dot chain line in FIG.
3, the fast-forwarding lever 8 returns to its original state due to the biasing force of the spring 9, and the tape recorder comes to a stopped state.

Next, when the magnetic tape automatically stops due to the end of the tape from the state shown in FIG.
2a is attracted in the direction of arrow U, and accordingly, the lock release lever Al6 into which the pin 22a is inserted moves to the fulcrum 1 in the direction of arrow W.
Rotate around 0. Up to this point, the above playback state (4th
The operation is the same as when the automatic stop occurs from the position shown in FIG. 5, but this time, as shown in FIG. Lock release lever B attached via
18 is rotated in the direction of arrow S by the biasing force of the spring 9, and is waiting at a position where it abuts against a rotation stopper 16c provided on the lever 6. Therefore, when the lock release lever Al6 rotates, the lock release lever Bl rotates integrally with the lock release lever Al6.
The part 18b of the lock lever 13 is not in a position to come into contact with the protrusion 13k of the lock lever 13, so it naturally does not come into contact with it. However, when the locking lever Al6 rotates, the part 16a of the locking lever Al6 is pushed into the protrusion 13 of the locking lever 13.
After making contact with j, the lock lever 13 is moved to the fulcrum shafts 13a, 13 in the same way as when changing from the regeneration state to the automatic stop state described above.
It is rotated by a predetermined angle in the direction of arrow C in FIG. 2 around point b. By rotating the lock lever 13, the lock pin 8 of the fast-forwarding lever 8, which is locked in FIG.
Since b is disengaged from the locking projection 13m of the locking lever 13, the fast-forwarding lever 8 is returned to the state shown in FIG. 1 by the biasing force of the spring 9.
The electromagnetic solenoid 21 and other levers return to the state shown in FIG. Next, in order to bring the tape recorder into the rewind state, the rewind lever 12 can be pushed from the state shown in FIG. When the rewind lever 12 is pressed in the direction of arrow 0, the lock pin 12b planted on the rewind lever 122 comes into contact with the protruding slope 13i of the lock lever 13, and then pushes it away, moving the lock lever 13 toward its axis. Rotate around the
Further, when the rewind lever 12 is advanced by a predetermined distance, the lock lever 13 is released from contact with the lock pin 12b, and operates in the same manner as the above-mentioned fast forward lever 8 is locked, and the lock pin 12b is locked by the locking protrusion 13n of the lock lever 13, and even if the operation of the rewind lever 12 is stopped, the rewind lever 12 maintains the state shown in FIG. 6 and moves in conjunction with the rewind lever 12. A mechanism (not shown) causes the tape recorder to enter a rewind state. In Figure 6,
The lever 21 that is interlocked with the rewind lever 12 is held moved in the direction of the arrow Q as in the fast-forward state described above, and the states of the lock release lever Al6 and the lock release lever Bl8 are also the same as in the fast-forward state. Since this is the same as the explanation in FIG. 5, detailed explanation will be omitted. Further, since the operation from the state shown in FIG. 6 to manual stop or automatic stop is the same as the operation from the fast forward state (FIG. 5), a description thereof will be omitted. Next, the operation of lever 0 shown in FIG. 1 will be explained.

The lever 10 is a lever used for operations related to the operating state of so-called review, cue, one-touch review, one-touch cue, etc., which will be described later. A slope protrusion 13h corresponding to the lock release pin 10b is provided at the end, and the protrusion 13h has the same shape as the above-mentioned protrusions 13g and 131 and the protrusion 13f described below. By pushing the lever 10 in the direction of arrow M, the lock release pin 10b moves forward, and the lock lever 13
After contacting the slope of the protrusion 13h, the lock lever 13
is rotated by a predetermined angle in the direction of arrow C in FIG.
13g and 131 in a similar locking process, that is, the fast-forward lever 8, the rewind lever 12, and the recording lever 6 described below, when a single lever or a plurality of levers are locked, this lever is locked. 10 works to release the lock (the regeneration lever 4 cannot be released because the locking method is different). Note that the lock release pin 10b provided on this lever 10 is similar to the other levers 6, 8, 1.
Since the position is different from pins 6b, 8b, and 12b of 2, L
The lever 10 is configured so that it is not locked by the lock lever 13 even if it is pressed a predetermined distance, and returns to its original position by the biasing force of the spring 11 when the operation is stopped. In FIG. 1, reference numeral 6 denotes a recording lever, and by pushing this lever, a circuit (not shown) provided in the tape recorder is brought into a recording state.

In the tape recorder according to the embodiment, when recording on a magnetic tape, the recording lever 6 and the playback lever 4 are normally operated at the same time to set the tape recorder to a recording state. Now, when both the playback lever 4 and the recording lever 6 are pressed in the directions of the arrows G and I, the lock pin 6b provided on the recording lever 6 will lock the lock lever 13 in the same way as when pressing the fast forward or rewind lever described above. When the lock lever 13 comes into contact with the protruding slope portion 13f and moves further, the lock lever 13 rotates around its axis, and when the lock lever 13 moves to a position where it can be locked by the lock lever 13, it is locked by the lock lever 13 and is pressed by the recording lever 6. Lever 6 does not return even if the operation is stopped. On the other hand, since the reproducing lever 4 operated together with the recording lever 6 is also locked by the means already described in the section on locking the reproducing lever, the tape recorder is in the state shown in FIG. 7, and the tape recorder is in the recording state. When canceling the recording state, as in the case of manually stopping or automatically stopping from the playback state described above, if the lock lever 13 moves in the direction of arrow B, each lever will be released from the lock, and the corresponding springs 3 and 5 will be released.
The lever is arranged to return to its original position. However, due to the structure of the lock lever 13 and the respective operating levers of this tape recorder, if the rewind lever 12, playback lever, and recording lever 6, etc. are operated from a state in which the fast-forward levers 2-8 are locked, the winding will start. When the fast forward lever 8, playback lever 4, recording lever 6, etc. are operated from a state in which the rewind lever 12 is locked, the rewind lever 12 is unlocked and the recording lever 6 is locked. When the playback lever 4, fast forward lever 8, and rewind lever 12 are operated in this state, the recording lever 6 is unlocked.

Next, three operations that are the features of this tape recorder will be explained.

(1) A tape recorder is required to search a predetermined position of a program recorded on a magnetic tape at high speed, and then play it back or wait there for playback.

This will be referred to as high-speed automatic head-to-four output. In other words, the head is positioned at a position where the next song can be played from the beginning. 1st
In the figure, when setting the high-speed automatic cue state, in the fast forward direction, the playback lever 4 is operated and locked first, and then the fast forward lever 8 is operated and locked, or these levers are operated and locked at the same time. done by doing. This high-speed automatic cue state is shown in FIG. That is, in the state shown in FIG. 8, with the magnetic tape being fed at high speed in the fast forward direction, a predetermined position on the tape (for example, an unrecorded portion on the magnetic tape between songs) is not shown. When a predetermined position on the tape is detected by a detection head, a circuit, etc., the fast-forward lever 8 must be unlocked in order to change the high-speed feed state to the playback state. Therefore, when the predetermined position of the tape is detected by the detection head and the circuit and the electromagnetic solenoid 21 is energized, the iron core 22 and pin 22a are attracted in the direction of the arrow U, and the lock release lever Al6 that is linked to this is installed on the main board 1. It is rotated in the direction of arrow W around the fulcrum shaft 10 that has been rotated. As mentioned above when setting the fast forward state, the lock release lever Bl8, which has the role of moving the lock lever 13 in the direction of the arrow B, cannot come into contact with the lever 24; The lock lever 13 is rotated in the direction of arrow S as shown in FIG.
It is located at a position where it does not come into contact with the contact portion 13k. Therefore, the lock lever 13 is not moved in the direction of the arrow A or B due to the rotational operation of the lock release lever Al6, and the part 16a of the lock release lever Al6 is moved toward the protrusion 1 of the lock lever 13.
3j, then move the lock lever 13 to its corresponding shaft 13.
Since the tape recorder is rotated by a predetermined angle around a and 13b, only the playback lever 4 and the fast-forward lever 8, which are locked by the lock lever 13, are released, and the tape recorder enters the playback state. To set high-speed automatic cueing in the rewinding direction, it is sufficient to operate both the playback lever 4 and the rewinding lever 12 shown in FIG. Explanation will be omitted.

By employing the locking method and release method for the lock lever 13 of the tape recorder as described above, it becomes possible to easily perform high-speed automatic cueing of the magnetic tape.

”) Manual high-speed cueing of a magnetic tape (generally called review or cue) will be explained.

In the case of the fast forward direction (cue), it is sufficient to operate the playback lever 4 as shown in FIG. Unlike when automatically cueing, in this case lever 10 is pressed at the same time, so lever 10
prevents the lock lever 13 from locking the fast forward lever 8. Therefore, in this case, if you stop pressing the fast-forward lever 8 and lever 10 at a predetermined position on the tape, these two levers will be moved by the springs 9 and 1.
1, respectively, and only the playback lever 4 is locked to the lock lever 13, and the tape recorder enters the playback state.
The playback operation will start from a predetermined position on the tape. In the case of review (manual cueing in the rewind direction), the rewind lever 12 is pressed instead of the fast forward lever 8 described above.

That is, by simultaneously pressing the rewind lever 12 and the lever 10 while the playback lever 4 is locked to the lock lever 13, manual cueing is possible as in the case of the cue described above. As described above, this tape recorder is equipped with a mechanism that allows easy review and cueing.

(3) Also, with this tape recorder, you can immediately perform the above-mentioned (1) with a single touch without having to perform a stop operation etc. from the recording state.
It is possible to perform high-speed automatic cueing as described in . That is, when performing this one-touch high-speed automatic cueing, first keep the tape recorder in the recording state, record on the tape a predetermined signal for locking the recording lever 6 and playback lever 4 in FIG. 1, and then leave the recording state as is. When the high-speed automatic cueing operation described in (1) above is performed, the recording lever 6 changes from the state where it is locked to the lock lever 13 as described above to the fast forward lever 1.
8 or when the rewind lever 12 is pressed, the previously locked recording lever 6 is released and then the fast forward lever 8 or the rewind lever 12 that is operated is locked to the lock lever 13. Since the tape recorder is structured so that the recording state is canceled and the tape recorder enters the high-speed automatic cueing state, the high-speed advance is canceled at a predetermined position on the tape and the tape is automatically played back at the same time. (4) Furthermore,
With this tape recorder, it is possible to perform high-speed manual cueing (review, cue) immediately from the recording state (without operating a stop lever or the like).

This is called one-touch review or cue. That is, the first
In the figure, both the playback lever 4 and the recording lever 6 are pressed and engaged with the lock lever 13. The tape recorder is now in recording mode as described above. In this state, a signal is recorded on the magnetic tape, and if the operation described in (2) above, that is, the rewind direction is performed from that state, the rewind lever 12 shown in FIG. When operated, only the recording lever 6 of the tape recorder is released from its lock, returns to its original position, and enters the rewind state, as described above.
