Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a tape player that uses the driving force of a motor to perform the mounting of the tapes 1 to 1 and the crimping operation of the head. .

[Technical Background of the Invention] Recently, automation of 7-blade players has progressed, and an O-1-rope ink mechanism has been proposed that automatically attaches and injects the Karen 1-. This 'A-1~ rowing mechanism is such that when the Karen 1- is inserted to the middle of the back kite, the force lever 1- is let to the playing position on the reel base by the driving force of the motor, and then The series of operations of moving the spatulas 1 through to press the tape against the tape is automatically performed by the driving force of the spatula 9. When this cassette is installed, J5 is used to store the driving force of the motor, and when the Ijiek I operation is performed (J,
By releasing the stored spring force, Karen 1~ is taken out from the playing position to the outside of the tape player.

In this type of sub-1 loading machine (tape play with 4 beats of 11), the mechanism for storing the spring for loading is a motor. Since it is performed by the driving force of , there is an advantage that the movements of Karen 1 to 1 can be performed with extremely light force.

``Problems with spine technology'' However, in the conventional tape player as described above, the loading of Karen i~ and the crimping of the head are performed as one continuous operation, so At d3, the backward movement of the head and the teasing 1~ movement of the cullet 1~ are performed all at once by the force of the spring stored in ``46'' of the cullet.As a result, the cullet There is a distinction between the so-called S1~Tubmort, which stops the playback of Karen 1~ by retracting the head with 1~ still installed in the tape player A, and the Ijiek [-], which takes out Karen 1~. This had the disadvantage that the cassette would be ejected immediately if the tape playback was stopped and the tape was stopped.If stop and eject were always performed in succession like this,
Even if you want to temporarily stop playing without having to replace Karen 1~, you have to take out Karen 1~, which is inconvenient for operation.

Also, from the head crimping to the cassette installation to these 4 certain people]
If steps up to 91 are performed continuously, there is a risk that the cassette may be tampered with before the head is fully pulled out from inside the cassette, and the head and cassette may become engaged, making it impossible to mount the cassette. .

[Object of the Invention] The present invention has been proposed in an attempt to solve the above-mentioned drawbacks of the conventional tape play. J, by loading the cartridges 1~ and crimping the head by the second operation 1), the I of ノJ t1-
A tape in which I-ding and I-cutting and crimping and retracting of the head are performed separately, so that it is possible to perform the stub operation with the 1-1-1 attached. The object of the present invention is to provide a driving force switching device for a player.

[Summary of the Invention] The driving force switching device 1%5 of the present invention controls the loading of the locking plate, which moves intermittently by the driving force of the motor, and the pulling plate of the head crimping mechanism by 3Tll! When the opening of the lock plate is moved for the first time, the lock arm separates the head crimping group 4i%1 and the pulling plate. Only the loading mechanism is operated, and after the loading mechanism reaches the device 5 position on the carre 1 and is locked by the lock arm, the The head crimping mechanism is actuated by the second movement of the plate.Example 31 Hereinafter, an example of the present invention will be described in detail based on the drawings.

■ Stop operation...Figure 13 P1/I 1 person r fortune telling Karen 1~ J-91~
The stop operation, which simply stops the playback of the Arp without pressing the button, is performed as follows. That is, when the lever 103 is pressed from the play state shown in FIG. A force is applied toward the body, causing the body to rotate in the same direction around its support axis. When you read,
The switch suppressing pieces 52 of the switch 1 to arm 50 are separated from the power supply ΔF switch J-51, and the switch
51 is ΔF and A1 to supply power and suction to the seventh gear and to the plunger 72. This means that the power supply will be removed.

When the power supply to the suction plunger 72 is released, the plunge link 70 is pressed by the roller-like engaging portion 35 and rotates in the counterclockwise direction. That is, the stopping position of the roller-like engaging part 35 is determined by the stopping position of the cam small lower 31 of the interlocking power play 1-30 in the middle of the linear return part of the two drive cams. It is located at a position slightly deeper than the return position of the stepped portion 37 of the tape brake. Therefore, when the plunge view/link 70 is in the shield-absorbing state, the vine plate 3G is pulled by the roller-like engaging portion 35 to the position iδ-C'
When the suction 6 flange A and 72 are de-energized in this state, 1) and 36 are held between the roller-shaped engaging portion 35 and the receiving roller 71 of the plunger link. , the lock plate 36 presses the plunger link 70 in an attempt to escape from the roller-like engaging portion 35, and the counterclockwise time a1
It will be rotated in the direction V. As the plunge A link 70 rotates in the counterclockwise direction, the holding plate 1-89 that is interlocked with the plunge A link 70 also rotates in the counterclockwise direction, and the step 93 and the engagement pin 84 of the head link 81 are connected to each other. The engagement will come off. When the spatula 1 to the link 81 is in a free state, the spring 87 installed between the head press bottle 86 and the tape player is rotated in the direction J and ii. As a result, as shown in FIG.
The entire engaged head play 1-94 is

Ru. Accordingly, as the tip of the shaft bar arm 57 moves toward the front, the cassette is pushed out from the inside of the back kite 1 by moving toward the front within the pack 1 to the collar 6.

In addition, as the stopper arm 58 rotates, the engaging claw 68 provided thereon pulls the connecting plate 66 toward the inner side.
The eject arm 50 is rotated clockwise by this connecting plate 66. Therefore, after the pushed in lever 103 returns to its original position and the pressing force against the eject arm 50 is released, the eject arm 1) 50 The switch suppressing piece 52 is pulled away from the power off switch 51 and remains in a one-turn state.

Also, when the sliding plates 1 to 40 retreat to the inner side and the engaging piece 46 of the lock arm 45 separates from the stepped portion 43, the tip of the lock arm 45 rotates clockwise and stops at And the head [f neck Ij! Since the front end of the pulling plate 77 is pressed outward, the engaging pin 84 of the head-side link 81 inserted into the elongated hole 79 of the pulling plate 77 engages with the engaging portion 80. It's in a position where it doesn't match, so it's difficult.
