ロツク機構に係るものである。Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a locking mechanism for a tape player. This relates to a locking mechanism for locking a member when it is being towed.
[発明の技術的背景]
最近テーププレーヤにおいては、各部材の移動
をモータの駆動力を利用して行うをのが広く採用
されている。[Technical Background of the Invention] Recently, in tape players, it has been widely adopted to move each member using the driving force of a motor.

Auto-reverse, which performs reciprocating playback and recording in the forward and reverse directions, auto-program change, fast-forwarding and rewinding of the tape, etc. are automatically performed using the driving force of the motor.

る。 Considering the head crimping mechanism in such an automated tape player, in order to advance and crimp the head automatically, it is necessary to transmit the driving force from the motor intermittently and selectively. The intermittent gear or the driving member, which has been locked and stopped by the electromagnetic plunger, is unlocked, and the intermittent gear is rotated by meshing with the gear on the motor side. The rotation of this intermittent gear causes the drive member to move back and forth, and in conjunction with this, the head advances and is crimped. When this is finished, the intermittent gear and the motor side gear disengage and the intermittent gear A so-called drive mechanism is used in which the rotation of the head is stopped and the driving force from the motor is no longer transmitted to the head crimping mechanism.

お、前進の完了したヘツド機構は別の保持手段に
より、この前進位置を保ちプレイ状態が続く。 A lock mechanism interlocked with this drive mechanism receives a detection signal indicating the start of operation when the drive member starts moving, and engages with a member on the head crimping mechanism side. After that, when the drive member continues to move forward, the locking mechanism that is interlocked with this lock mechanism remains engaged with the head crimping mechanism and pulls the head crimping mechanism until the head is in the position where it is crimped onto the tape, and the drive member moves back. When it returns to its original state, the engagement state is released and the drive mechanism side and the head crimping mechanism are separated. It should be noted that the head mechanism, which has completed its forward movement, is maintained in this forward position by another holding means, and the playing state continues.

A lock mechanism is essential that connects the driven mechanism to the drive mechanism when the mechanism starts operating, and disconnects the two when the operation is completed.

能となる事態が生ずる。[Problems with the Background Art] However, the conventional lock mechanism receives a signal to start transmitting the driving force, locks the mechanism on the driven side, and then maintains the locked state at all times until the end of the transmission of the driving force in that mechanism. Because of its structure, if the power to the tape player itself is cut off for some reason while the driven mechanism is being towed, the driving mechanism will stop and the driven mechanism will also be locked and stop midway. It turns out. For example, if we consider a head mechanism, a conventional lock mechanism has a structure that receives a signal to start transmitting driving force, locks the head mechanism side, and then maintains a locked state at all times until the head mechanism stops moving forward. Therefore, if the power to the tape player itself is cut off for some reason while the driving force is being transmitted, the drive mechanism will stop and the head mechanism will also be locked and stop midway. If the power is turned off while the head is moving forward, the cassette remains inserted and cannot be fully loaded or injected, making it impossible to turn on the power again.

のロツク機構が望まれているのである。 As tape players become more automated, if the power is turned off for some reason, the driven parts will remain locked in the middle of operation, and operation will not resume even if the power is turned on again. There is a need for a locking mechanism between the driving mechanism and the driven side that can cope with such failures.

づけられる。 Before the driven member starts moving forward...Figure 1 When the power to the tape player is turned on, the electromagnetic plunger 1 is turned on, the plunger plate 2 rotates around the shaft 2b, and the attraction piece 2a is attracted to it. , the plunger plate 2 is fixed. When the plunger plate 2 rotates in this way, the hold plate 3 connected thereto also rotates around the shaft 3a, and the attraction force of the electromagnetic plunger 1 reaches a position where its guide portion 3b is oriented in the width direction of the tape player. Fixed by Then, the lock plate 4, which is connected to the hold plate 3 by the connecting shaft 3c, rotates around the fixed connecting shaft 3c, and in this state, it rotates clockwise in the figure due to the biasing force of the spring 4s. The holding plate 3 almost overlaps with the holding plate 3. At this time, the hook plate 5 rotatably attached to the driven member 11 is rotated about the mounting shaft 5a because its lock pin 7 contacts the guide portion 3b of the rotated hold plate 3 and is pressed. Rotates counterclockwise in the figure. Then, the lock pin 7 comes into contact with the side edge 24 of the opening of the tape player and stops rotating, and the lock pin 7 is sandwiched between the side edge 24 of the opening and the guide portion 3b of the hold plate 3. . As a result, the mounting shaft 5a of the hook plate 5, the lock pin 7, and the connecting shaft 3c of the hold plate 3 are aligned in a straight line, and the lock pin 7 moves between the side edge 24 of the opening of the tape player and the guide portion 3b of the hold plate 3. be directed to do so.

の前進は完了する。 Completion of forward movement of the driven member...Fig. 2 In this state, the driving member 6 continues to move forward, and when it reaches the end of its movement stroke, the lock pin 7 of the hook plate 5 passes the pressed portion 4c of the lock plate 4 and is locked. The plate 4 returns to the direction in which it locks the lock pin 7 due to the biasing force of the spring 4s, and the lock pin 7 engages with the lock portion 4b and locks the driven member 11.

When the power plate 6 returns to its original position, the engagement pin 8 at the tip of the drive member 6 also disengages from the engagement portion 5b of the hook plate 5 and moves to the right in the tape player slot 9. This prevents the hook plate 5 from being pulled.

である。 However, since the lock pin 7 on the hook plate 5 remains engaged with the lock portion 4b of the lock plate 4, the driven member 11 does not move backward but maintains its forward position. That is, since the hold plate 3 is fixed, the lock plate 4 rotates around the connecting shaft 3c. At this time, if the stepped portion of the lock portion 4b is at a right angle, the mounting shaft 5a of the hook plate 5, the lock pin 7, and the connecting shaft 3c rotate. Since the shafts 3c are on the same straight line, the force that urges the driven member to the right in the figure by the springs 12 and 13 acts on this straight line,
In order to press the stepped portion of the lock portion 4b at right angles, the spring 4
It does not rotate against the biasing force of s,
The lock pin 7 and the lock portion 4b maintain their engagement.

Since the hold plate 3 is no longer fixed, the lock plate 4 has been replaced with the conventional connecting shaft 3c.
Instead, the holding plate 3 is rotatable around the axis 3a. The traction force on the driven member 11 by the springs 12 and 13 is applied along the line connecting the shaft 3a and the lock pin 7, and acts diagonally on the lock portion 4b, so that the traction force on the driven member 11 is applied to the lock plate 4 in the lateral direction. A moment force acts, and the lock plate 4 rotates counterclockwise. As the lock plate 4 rotates in the counterclockwise direction, the connecting shaft 3c
The driven member 11 also rotates and deviates from the line of movement l of the driven member 11, and then the traction force of the driven member acts in a direction that connects the lock pin 7 with the connecting shaft 3c eccentric from the straight line l. Coupled with the eccentric action of the shaft 3a, the angle of inclination between the lock part 4b and the straight line l becomes larger, and the lock pin 7 slides on the lock part 4b, pushing up the lock plate and moving to the right in the figure. The drive member is unlocked.

つて後退することになる。 If the power is cut off while the driven member is moving forward...
FIG. 4 If the power to the tape player is cut off for some reason while the driven member is moving forward, that is, before the lock pin 7 engages with the stepped portion 4b of the lock plate 4, the driving member 6, which had been moving forward, will It stops in the middle of its forward movement. Therefore, the engaging pin 8 that was pulling the driven member 11 and the hook plate 5 stops within the elongated hole 9 of the tape player while engaging the engaging portion 5b of the hook plate 5. At this time, the electromagnetic plunger 1 turns OFF and stops attracting the plunger plate 2, which was previously attracted.
The plunger plate 2 and the hold plate 3 connected thereto are no longer fixed, and the hold plate 3 becomes rotatable about the shaft 3a. Therefore, the hook plate 5, which had been fixed without being able to rotate by sandwiching the lock pin 7 between the guide portion 3b of the hold plate 3 and the side edge 24 of the opening of the tape player, is now released from this state and can be rotated. It is free to move. And spring 12,
The driven member 11, which has been pulled in the forward direction against the urging force of the springs 13, will move backward according to the urging forces of the springs 12 and 13 when the pulling force is removed.

フツクプレート5との係合は離れる。 At this time, the engagement portion 5b of the hook plate 5 that was engaged with the engagement pin 8 on the drive member 6 is released from the engagement due to the following force action. If the depth of the stepped portion of the engaging portion 5b of the hook plate 5 is shorter than the radius of the engaging pin 8, the force of pressing and fixing the hook plate 5 from above in the figure is lost, and the springs 12, 13 are When the biasing force acts to the right in the figure, the corner of the stepped portion of the hook plate 5 is pressed so as to slide on the circumference of the engagement pin 8, and the hook plate 5 is rotated clockwise. Furthermore, even when the engaging portion 5b of the hook plate 5 is tapered,
Similarly, since the tapered portion slides onto the engagement pin 8 and is pressed, the hook plate 5 rotates, and the engagement between the engagement pin 8 and the hook plate 5 is released.
