The present invention relates to a cassette deck with an automatic selection function, by connecting the direction change lever moving with the F / R gear arm by the operation of the cue / review lever so that the cue / review operation can be made freely, The tapered end of the magnet forms a tapered shape, and the magnet bar is pulled, pushing the F / R lock lever to push the cue / review lever to release the cue / review lever, so that the play can be performed accurately and the guide holder can be detached from the head. It aims to provide the deck with high quality by preventing the malfunction of the device and the occurrence of noise by pushing the pin roller roll arm and acting as the guide of the tape when the head chassis is reversed.

In the conventional deck, the F / R lock lever and the assembled bracket are pulled by an electromagnet with an electromagnet to release the locked F / F lever and the rewind lever, and the bracket is rotated to push the F / R lock lever. In the case of angular deviation between brackets and electromagnets, there was a problem such that the bracket could not properly push the F / R lock lever due to the weakening of the magnetic force. There was a problem that the deck which installed the holder which adopts other slide and rotation method was conceived, but the configuration was complicated and the operation was not accurate and the reliability was lowered.

The present invention is conceived in order to achieve a precise and smooth connection operation between each component in view of the conventional problems as described above in detail based on the accompanying drawings as follows.

The F / R gear arm (2) and the play idle lever (3) to which the F / F gear (4) and the rewind gear (5) are attached are connected to the F / R spring (6), and at the same time, the F / R gear arm While inserting and connecting one side of the direction switching lever 9 to which the cue (F / F) lever 7 and the review (rewind) lever 8 are connected to the inclined hole 2a installed on one side of the head (2). (10) The support protection guide holder 11 is attached to the head chassis 12 so as to be detachable, and is formed on the side of the F / R lock lever 13 that locks the lever 7 and the review lever 8. The tip of the stone piece 3a The electromagnet 14 is installed so that the magnet rod 14a formed in the tapered shape of the die is vertically slid, and the guide holder 11 on which the head 10 is seated and fixed is guided to guide the tape to both sides. 11a) is elongated, and on one side thereof, a head retraction shaft 15 sliding with the lever 7 and the review lever 8 is mounted in the head chassis 12, and the head retraction shaft 15 is provided. A slide-rotating roller 15a is installed at the tip to minimize friction force when the cue / review lever moves forward and backward, while the cue / review levers 7 and 8 have protrusions 9a of the reversing lever 9 at the end. The guide hole 7a (8a) having this curved surface (b) (b ') to be inserted is laid so as to face each other, and the stone bar (9a) is guided to move along the surface (b) (b') of the direction change lever. (9) is to move the F / R gear arm (2) up and down.

In the figure, reference numeral 21 denotes a cap for preventing separation of the magnetic rod 14a, and M denotes a motor.

Referring to the operation and effects of the present invention, the program cam 16 rotates clockwise as shown in the first diagram, the program arm 17 moves upward, and the play idler lever 3 moves slightly counterclockwise. F / R gear arm 2 connected to F / R spring 6 moves in the direction of T reel and is engaged with F / F gear 4 and T reel gear T attached thereto (play state) Press the Cue lever 7 as shown in Fig. 2 (the program is selected in the R / F direction) and the stone bar of the turning lever 9 inserted into the guide hole 7a of the Cue lever 7 9a is hardly influenced by the bent portion b (because the F / R geararm 2 is moved upward in advance by the F / R spring 6). While moving forward, the head chassis 12 is pushed back into the head chassis 12 so that the head chassis 12 retreats in the right direction so that the head 10 also retreats with the head chassis 12. The front end of the head will reverse shaft 15 there is a slide for rotating the rollers (15a) yuseol in order to reduce the friction when advancing the queue lever 7.

In this way, the advanced lever 7 is locked to the F / R lock lever 13 located at the front end thereof and stops without being reversed. The pinch installed in the head chassis 12 when the head chassis 12 is retracted is stopped. The roller spring 18 pushes both pinch roller arms 19 so that the pinch rollers 19a are spaced apart from the rotation shaft 20.

At this time, the tape is guided to the guider 11a elongated to the guide holder 11 and continues to be wound in the F / F direction. When a selection signal is detected at the head 10, an electric current is instantaneously applied to the electromagnet 14. And pulls the magnet rod 14a, so that the tapered tip of the magnet rod 14a on which the transverse piece 13a of the F / F lock lever 13, which has been collected on the magnet rod 14a as in the eighth degree, descends, By doing so, the lever (7) held by the F / F lock lever (13) is released to return backward, and at the same time, the head (10) and the pinch roller (19a) are also in the original position.

In addition, when the user wants to rewind the tape in the state of FIG. 1 and presses the review button 8 as shown in FIG. 4, the head 10 is reversed as in the electrical operation so that the pinch roller 19a and the rotating shaft 20 are separated from each other. Is the same as the operation of locking the front end of the review lever 8 to the F / F lock lever 13, but in this case, the review lever 8 moves forward to the curved portion b 'of the guide hole 8a. As shown in FIG. 5, the stone bar 9a of (9) is guided so that the turning lever 9 is moved slightly counterclockwise about the fixed shaft a fixed to the chassis 1 and thus F / The other end of the turning lever 9 inserted in the inclined hole 2a of the R gear arm 2 is pulled downward to pull the F / R gear arm 2 so that the F / F gear 4 falls and rewinds. The gear 5 is engaged with the S reel gear S and is in a review state. When a selection signal is detected at the head 10, a current is applied to the electromagnet 14 to provide a magnet rod ( 14a) is pulled out, the review lever 8 is released, and the F / R gear arm 2 is moved by the F / R spring 6 in the direction of the T reel and the T / R gear arm 2 moves again in the T reel gear. The F / F gear 4 meshes with (T).

On the other hand, as shown in FIG. 6, the program arm 17 moves downward to move the play-adler lever 3 clockwise slightly so that the F / R gear arm 2 connected to the F / R spring moves in the S-reel direction. When the rewind gear 5 attached here is engaged with the S reel gear S (reverse state) and the cue lever 7 is pressed as in the seventh degree, the lever lever 7 moves forward. The turning lever 9 inserted in the inclined hole 2a of the F / R gear arm 2 is pushed clockwise along the curved portion b of the guide hole 7a. 9) The F / R gear arm 2 is pushed in the T-reel direction by the other end, and the F / F gear 4 attached to the F / R gear arm 2 is engaged with the T reel gear T to cue. When the selection signal is detected in the head 10, a current flows to the electromagnet 14, and the F / R lock lever 13 is pushed by the magnetic rod 14a to release the cured lever 7 which is locked. Being home As the F / R gear arm 2 is returned to the S reel direction by the F / R spring 6, the F / F gear 4 is dropped from the T reel gear T and the rewind gear 5 again moves to the S reel. It is a match. In addition, in the state of FIG. 6, when the review lever 5 is pressed, only the review lever 5 moves forward without moving the direction change lever 9 so that the head 10 is reversed, and the rewind gear 5 is an S reel gear. The review state is achieved by being fitted to (S), and a selection signal is sensed by the head 10, and the review lever 8, which was caught on the F / R lock lever 13 by the electronic type 14, is returned to its original position. .

In this way, the present invention constructs a turning lever 9 which is operated by guide holes 7a and 8a installed in the cue / review lever 7 and 8, and is attached to the F / R gear arm 2 by F. The / F gear 4 and the rewind gear 5 are selectively engaged with the T reel gear T and the S reel gear S so that the selection function can be smoothly performed in any state. The guide holder 11 with the tape guide guide 11a extended vertically to support the head 10 and to stabilize the running of the tape, thereby improving the reliability of the deck and at the same time the F / R lock lever 13 The tip is " By installing the electromagnet 14 having the magnet rod 14a formed in the tapered shape of " It is effective in eliminating malfunctions caused by failures, and it is a new useful product that further enhances the practical use value which completely solves the conventional defect that the head was spaced too much from the tape during the cue / review operation and the accurate selection was not achieved. It is an idea.
