143 etc. are provided.

It has the above configuration, and its operation will be explained next.

To perform playback first, push the playback button 29 in the -Y direction against the elastic force of the leaf spring 30,
As shown in the figure, the first sliding plate 8 slides in the -Y direction, and accordingly, the protrusion 23 of the lock lever 25 corresponds to the notch 26, so that the lock lever 25 is moved by the tension coil spring 5.
9, the notch 26 of the lock lever 25 enters the protrusion 23 of the first sliding plate 8, and the first sliding plate 8 is locked. .

On the other hand, the recording/reproducing magnetic head 6 fixed to the first sliding plate 8 enters into the cassette through an opening 134 formed on the side surface of the cassette and comes into contact with the tape 135. A pinch roller 15, which is rotatably attached to the first sliding plate 8, is driven by the sliding plate 8, and is elastically pressed against the capstan 127 with a constant pressure by the action of the torsion spring 18, so that the tape can be accurately pressed. make it run. In addition, the pin 23 provided at the tip of the brake lever 22 is pushed down by the notch 21 formed below the first sliding plate 8, so that the brake lever 22 rotates counterclockwise about the pin 122 as a fulcrum. Then, the brake piece 121 fixed to the brake lever 22 is separated from the joint reel 86, and the joint reel 86 becomes rotatable. As the first sliding plate 8 slides down, the protrusion 128 of the first sliding plate 8 turns a switch (not shown), the motor 4 rotates at a constant speed, the capstan 127 rotates, and the tape 135 is rotated. is running at a constant speed,
The take-up reel gear 93 is rotated from the flywheel gear 98 via the intermediate gear 97 which is normally moved in the x direction by the lever 117 against the spring 119, and the take-up reel 82 is rotated to wind the tape. and enters the playback state. Next, when the tape 135 reaches the end in the above playback state, the tape end is fixed to the hub 136, so the lever 88 to which the supply reel 86 is attached is moved by the tension of the tape to the hub 136 of the cassette tape 132. It is rotated clockwise about the pin 85 by the amount of play.

As the lever 88 moves, one end 92 of the lever 61 attached to the arm of the lever 88 moves to the take-up reel gear 93.
The first end 92 of the bar 61 is kicked by the protrusion 94, and the lever 61 is rotated counterclockwise. As the lever 61 rotates, a pin 62 provided at the end of the lever 61 pushes the end surface 60 of the lock lever 25, and the lock lever 25 rotates clockwise against the spring 59 using the pin 58 as a fulcrum. The protrusion 23 of the first sliding plate 8 is disengaged from the notch 26 of the lock lever 25, the lock of the first sliding plate 8 is released, and the regenerated nail 29 is moved to the first sliding plate 8. At the same time, the restoring force of the leaf spring 30 returns it to its original position, and a so-called automatic stopping operation is performed. If you want to stop normal playback,
All you have to do is push the stop plow 63 in the -Y direction.

That is, by pushing the stopper 063 in the -Y direction, the third
The protrusion 71 of the lock lever 25 is pushed by the slope 70 formed on the sliding plate 64, and the lock lever 25 is rotated clockwise to be unlocked from the first finger plate 8, and the play button 29 is released.
returns to its original position. Next, to explain the rewinding and fast forwarding operations, as shown in FIGS. 7 and 8, the reproducing plow 29
When the recording output 36 is inactive, rewinding is performed by pushing the rewind/fast-forward lever 100 in the -x direction.

That is, as the rewind/fast forward lever 100 moves in the - A lever 95 equipped with an intermediate gear 97 is slid in the x direction by a spring 119, and the intermediate gear 97 is disengaged from the take-up reel gear 93 and meshes with the rewind gear 84. Also rewind and fast forward lever 10
The pin 113 set at 0 is located at position 114b of the slot 114 formed in the first sliding plate 8, and the brake release lever 46 is located at the position 114b of the slot 114 formed in the first sliding plate 8. 106 as a fulcrum, and a roller 107 attached to the brake release lever 46 is iron-fitted to a recess 112 at one end of the V-groove 105.
The rewind/fast forward lever 100 is locked. On the other hand, as the lever 46 is rotated, the lower end 123 of the brake release lever 46 pushes down the tip 129 of the brake lever 22, and the brake lever 22 is rotated counterclockwise about the pin 122 as a fulcrum. The brake piece 121 fixed on the brake piece 22 is separated from the supply reel 86, and the supply reel 86 becomes rotatable. Also, the brake release lever 46
A switch (not shown) is turned on by the protrusion 130 at the other end.
Therefore, the motor 4 rotates at a higher speed than the rotation speed during the regeneration, and the rotation of the motor 4 is as follows: flywheel 5 - flywheel gear 98 - intermediate gear 97 - rewinding gear 84 -
The signal is then transmitted to the supply reel gear 89, and the supply reel 86 is rotated at high speed in a counterclockwise direction, which is the opposite rotation to that in the playback state, thereby rewinding the tape. Next, when performing fast forwarding from the stopped state, use the rewinding and fast forwarding lever 100.
Slide in the x direction. Then, the lever 117 remains in its normal state, the intermediate gear 97 meshes with the take-up reel gear 93, and the roller 107 of the brake lever 46 fits into the recess 109 of the V-groove 105 of the rewind/fast-forward lever 100.
The lever 100 is locked. Furthermore, the brake is released in the same manner as in the rewinding operation, the switch is turned on, and the motor 4 rotates at high speed at the same time as the rewinding operation. 93, the tape 135 is wound at high speed, and fast forwarding is performed. next,
To perform a rewind operation, that is, a review operation in the playback state, push the rewind/fast forward lever 100 in the 1x direction as shown in FIG.

Then, at the same time as the rewinding operation, the tape 135 is rewound while being played back.
Since the pin 113 is located at the position 114a of the slot 114 formed in the first sliding plate 8, the roller 107 of the brake release lever 46 can only slide to the position of the slope portion 111 of the V register 105. Therefore, the rewind/fast-forward lever 100 is not locked, and returns to its original position when the external force (pressing force with a finger) is removed by the tension coil spring 108 and the slope of the V-groove 105. Furthermore, during the viewing operation described above, the rotating direction of the capstan shaft 127 and the running direction of the tape 135 are reversed, so it is necessary to separate the pinch roller 15 from the capstan 127. Therefore, when the transfer bar 117 rotates clockwise, the protrusion 120 of the lever 117 pushes up the pin 19 that is shielded from the lever 16 to which the pinch roller 15 is attached, and the lever 16 uses the pin 14 as a fulcrum. It is rotated clockwise so that only the pinch roller 15 is separated from the capstan 127. In this case as well, the switch is turned on by the protrusion 130 of the brake release lever 46, the motor 4 rotates at high speed, and the tape is rewound at high speed. Next, a so-called cue operation in which fast-forwarding is performed in the playback state is performed by pushing the rewind/fast-forward lever 100 in the X direction in the playback state, as shown in FIG.

That is, when the rewind/fast-forward lever 100 is pushed in the X direction, the rewind/fast-forward lever 100 moves when the roller 107 on the brake release lever 46 moves toward the slope part 110 of the V-groove 105 during this cue operation as well as the view operation described above. The pinch roller 15 is not locked because it can only be slid up to this position, and in this case the pinch roller 15 is in pressure contact with the capstan 127, but when the brake release lever 46 is rotated, its protrusion 130 turns on the switch. Since the capstan 127 rotates at high speed due to the high speed rotation of the motor 4,
The tape will be fast forwarded and will be in a queue state. Note that during these playback, rewind, fast forward, review, and cue operations, eject operations, which will be described later, are not possible.

That is, by rotating the brake lever 22, the lever 22
The end 26 of the lever 77 is pushed up by one end 125 of the lever 77, and the lever 77 rotates clockwise about the pin 131 as a fulcrum. By turning the lever 77, the eject lever 73 is moved to the pin 76 by a pin 78 provided on the lever 77.
The distal end 74 of the eject lever 73 and the lower end 72 of the third betting plate 64 are disengaged from each other, thereby preventing an unexpected ejecting operation. Next, the recording operation will be explained. First, a recordable cassette tape, that is, a cassette tape with fins 133 attached to the cassette, is loaded, and when the second sliding plate 32 is moved in the direction of arrow -Y against the spring 37 with the recording button 36, its protrusion As the portion 51 retreats, the fin detection lever 39 is rotated in the rebound direction by the spring 49, and the fin support portion 48 comes into contact with the fin 133.
However, in this case, the rotation of the fin detection lever 39 is extremely small, and the engagement between the flower piece 38 of the second sliding plate 32 and the notch 40 of the fin detection lever 39 is still in a non-engaged state. The second sliding plate 32 can slide in the -Y direction. When the green sound button 36 is pressed and the playback gold 029 is pushed in the -Y direction, the playback nail 29 is locked in the same way as in the above-described playback operation, and the tape 135 is run at a constant speed. By being pushed in the −Y direction, the projection 43 of the lever 27 rotatably mounted on the second emotion plate 32 disengages from the cassette guide pin 44, and the lever 27 is moved by the tension coil spring 42. Since it is biased in the opposite direction, the notch 28 of the bar 27 is engaged with the protrusion 24 of the first betting plate 8, and the edge button 36 is locked together with the second sliding plate 32. , the state of being pushed in one Y direction is maintained. Due to the movement of the second sliding plate 32, the erasing magnetic head 31 fixed to the sliding plate enters into the cassette through the opening 137 formed on the side surface of the cassette, contacts the tape 135, and at the same time moves the second sliding plate 32. The lever 54 is rotated counterclockwise by the retreat of the notch 52 of 32, and the recording/playback selector switch 57 is switched to the recording side by the pin 56 provided on the lever 54, and the playback/recording magnetic head 6 is switched to the recording side. The recording operation is performed. Next, when the cassette tape from which the fins 133 of the cassette have been removed, i.e., the cassette tape from which existing recordings are not to be erased, is loaded, when the recording outlet 36 is pushed in the -Y direction, the fin detection lever 39 is moved counterclockwise. As the protruding portion 48 is inserted into the fin cut-out entrance portion 138 of the cassette, the fin detection lever 39 rotates greatly, and the notch 40 engages with the hanging piece 38 of the second sliding plate 32. Thus, the second sliding plate 32 is prevented from sliding in the -Y direction.

Therefore, the recording plow 36 cannot be pushed substantially in the -Y direction, and accidental recording is prevented. On the other hand, in the recording state described above, if the rewind/fast forward lever 100 is pushed in the When moving in the direction, the rewind/fast forward lever 100
A V groove 105 formed in the brake release lever 4
6 rotates clockwise, the protrusion 47 of the lever 46 pushes the pin 45 shielded on the lever 27, and the lever 2
7 rotates clockwise to disengage the protrusion 24 of the first sliding board 8 from the notch 28 of the bar 27, so that the recording spade 3
6 is unlocked, the second sliding plate 32 is returned to its original position by the restoring force of the tension coil spring 37, and the recording/playback switch 57 is switched to the playback side, and in this state, the same operation as above is performed. A review or cue action takes place.

Then, when the forward view or cue operation is canceled, the playback state is entered.In particular, when the review operation is canceled, the previously recorded content can be immediately listened to. Furthermore, if you want to cancel the above-mentioned recording state, press the stop button 63 in the same way as when stopping playback.
By pushing in the -Y direction, the first sliding plate 8 is unlocked and returned to its original position as described above.

At this time, the second sliding plate 32 is driven by the first restraining plate 8 and
Along with this movement, the cassette guide pin 44 and the protrusion 43 of the bar 27 move the bar 27.
is rotated clockwise, the engagement between the notch 28 of the lever 27 and the protrusion 24 of the first sliding plate 8 is released, and the second sliding plate 32 is unlocked and returned to its original position. Return. Finally, the ejecting operation is performed by pushing the stopper 63 in the -Y direction in the stopped state.

That is, when each operation button is inactive, the third sliding plate 64
Since the lower end 72 of the eject lever 73 is engaged with the tip 74 of the eject lever 73, by pushing the stop plow 63 in the -Y direction, the eject lever 73 is pressed against the third sardine plate 63 and -
Slide in the Y direction. At this time, the flea 79 provided on the eject lever 73 pushes up the roller of a pocket (not shown) into which the cassette tape 132 is inserted, and the pocket is raised to a predetermined position, allowing the cassette to be easily removed. be able to. Note that this eject operation is impossible during playback (recording), rewind, fast forward, review, and cue operations as described above.

As described in detail above, the present invention provides a first substrate for playback, recording,
An operating member for stopping is arranged, the second board is equipped with an operating member for rewinding and feeding the reel, a reel, and a first rotating body for rotating the reel, and the third board is equipped with a motor, The mechanism is completed by arranging capstans, etc. and joining the three boards mentioned above. This allows each part to be attached from one direction on each board, and it is possible to attach paper to each part from one direction on each board. With this, the number of parts is greatly reduced and the configuration is simplified, making assembly and adjustment much easier compared to the conventional method of roughly attaching parts using both sides of a single board. This is extremely useful for cassette-type tape recorders because automatic assembly becomes possible and quality stability is promoted.
