The present invention is to load the cassette tape by the clutch in VYR. When the cassette tape is seated, the worm rotation shaft with the projection is inserted into the groove of the idler where the fleece of the loading motor and the convex and the concave portions are fitted to each other. In the housing dignity integrated with the rotating shaft, the loading gear connected through the interlocking gear rotates so that the cassette tape is seated along the guide hole on the side wall of the housing. After the cassette tape is seated, the cam groove of the master cam interlocks with the pulley of the loading motor. The pinned slide plate moves down to rotate the clutch, and the other side of the clutch pushes the outer edge of the idler to release the engagement of the pulley and the idler of the loading motor, thereby dignifying the housing's dignity by rotating on the shaft of the loading motor. By loading gear And to rotate relates to a tape cassette loading apparatus according to the clutch of a VTR to occur so operation is stable.

Conventionally, the operation of extracting the cassette tape by inserting it into a seat or ejecting it is performed by a loading motor, and the driving of the seated cassette tape is performed by a separate motor. There is an inconvenience in that the loading of the cassette tape is made by one loading motor, and the cassette tape is driven while idling the gear of the housing while the cassette tape is fully seated, but the housing gear is idling. There was a lot of inconvenience in use, such as a complicated operation frequently occurs.

The present invention for compensating such a disadvantage of the conventional slide plate integrally the worm rim to the pulley of the loading motor and the belt connected to the belt, the pin is inserted into the cam groove of the master cam is rotated in engagement with the worm and the gear plate to operate up and down By forming a bow on the other side of the clutch that rotates around the shaft by pushing one side by the pulley of the loading motor and the convex part and the concave part of each other so as to be in contact with the outer edge of the rotating idler, thereby pushing it. The idler is rotated and inserted into the cassette tape by the dignity of the housing, and when it is seated, the slide plate with pins inserted into the cam groove of the master cam moves downwards and the clutch rotates about the axis so that the idler loads the motor. Loading by dismantling in combination with the pulley of Described in detail by the accompanying drawings, that it allows the housing to idle the worm axis of rotation of the emitter axis sikilsu gwansap to the tape cassette mounting the gears on the stopping state continuously driven as follows.

In the VTR, the convex portion 2-2 and the concave portion 2-3 are integrally formed on the extension portion 2-1 on one side while rotating together with the loading motor 1 on the same axis 1-1. A motor pulley (2) and a belt (3) are connected to interlock the worm pulley (4), and the gear and the worm (4-1) integral with the worm pulley (4) mesh with the shaft (5-1). The rotating plate 6, in which the pin 6-1 is fitted into the inward groove 5-2, the inclined groove 5-3 and the outer shaft groove 5-4, has a long slot 6-2. Clutch 7 to be operated up and down by the stud (6-3) inserted into the bent, and the bent portion (7-1) in contact with the slide plate (6) is integrated on one side and rotates about the shaft (7-2) The bow 7-3 is integrally formed on the other side of the head), the outer periphery 8-1 is caught by the bow 7-3 of the clutch 7, and the convex part 2-2 of the motor pulley 2 is formed. ) And a shaft hole 8-5 in which the recess 8-2 and the convex portion 8-3 fitted with the recess portion 2-3 are integral and the groove 8-4 is integrally formed on the inner surface thereof. children The worm is inserted into the groove 8-4 and the projection 9-1 has the elasticity of the coil spring 10 to the worm rotation shaft 9 which is integrally inserted into the reciprocating lamp, and the worm rotation shaft 9 The cassette tape inserted into the housing 13 is seated and ejected along the guide hole 13-1 by rotating the loading gear 12 through the interlocking gear 11 in the housing worm 9-2 integral with the housing. It is done.

Reference numeral 14 is a cassette tape.

In this invention, when the cassette tape 14 is pushed into the housing 13, as shown in FIGS. 1 and 2, the loading motor drive switch (not shown) is driven by the cassette tape 14. The loading motor 1 is driven while being connected.

Then, the block portion 2-2 and the concave portion 2-3 and the concave portion 8-2 of the extension portion 2-1 integrated with the motor pulley 2 which is coaxial with this 1-1 and The worm rotation shaft 9 in which the projection 9-1 is fitted into the groove 8-4 of the idler 8 to which the convex portion 8-3 is fitted and rotates also rotates.

Therefore, the cassette tape 14 inserted into the housing 13 is rotated while the loading gear 12 interlocked through the interlocking gear 11 rotates in accordance with the rotation of the housing worm 9-2 integral with the worm rotation shaft 9. The master cam meshes with the worm 4-1, which is integral with the worm pulley 4, which is connected to the motor pulley 2 and the belt 3 and interlocks with each other, while being guided along the guide hole 13-1. (5) to rotate so that the pin 6-1 of the slide plate 6 fitted in the inner groove 5-2 of the master cam 5 reaches the inclined groove 5-3 to move downward. At this time, the accurate reciprocating motion is made up and down by the stud (6-3) inserted in the long hole (6-2).

As the cassette tape 14 is seated as described above, the slide plate 6 moves downward while pushing the bent portion 7-1 of the clutch 7 to rotate about the shaft 7-2 to move the bow portion ( 7-3) pushes the outer edge portion 8-1 of the idler 8.

Then, when the cassette tape 14 is completely seated, the pins 6-1 of the slide plate 6 are positioned in the outer grooves 5-3 of the master cam 5 as shown in FIGS. 3 and 4. The clutch 7 is rotated about the shaft 7-2 while completely moving downward so that the bow 7-3 completely pushes the idler 6.

Therefore, the concave portion 8-2 and the convex portion of the idler 8 engaged with the block portion 2-2 and the concave portion 2-3 formed in the extension portion 2-1 of the motor pulley 2 ( Since the 8-3) is dismantled, the cassette tape 14 is inserted because the worm rotation shaft 9 which is inserted into the shaft 1-1 of the loading motor 1 and is idle does not operate regardless of the driving of the loading motor 11. The driving of the loading motor 1 in the seated state allows the deck to be driven.

When the cassette tape 14 is ejected, the master cam 5 is reversely rotated by the loading motor 1, so the pins 6- 6 are inserted into the cam grooves 5-2, 5-3, and 5-4. Since the slide plate 6 with 1) moved upward and the force pushing the outer periphery 8-1 of the idler 8 is reversed, the idler 8 and the clutch ( As the 7 is reduced to its original state, the concave portion 8-2 and the convex portion 8-3 of the idler 8 are connected to the convex portions 2 and 2 and the concave portion 2-3 of the motor pulley 2. The housing worm (9-2) is reversely rotated by the reverse driving of the loading motor (1) by being engaged to rotate the loading gear 12 through the interlocking gear (11) to eject the cassette tape.

In this manner, the slide plate 6 in which the pins 6-1 are fitted into the cam grooves 5-2, 5-3, and 5-4 of the master cam 5 and thereby the shaft 7-2 is centered. The bow portion 7-3 of the clutch 7 which rotates in the direction pushes the outer periphery 8-1 of the idler 8 and the block portion 2-2 and the recess portion 2-3 of the motor pulley 2 are rotated. ) And the concave portion 8-2 and the block portion 8-3 of the idler 8 are engaged or released to transmit or idle the drive of the loading motor 1 to the housing worm 9-2. When the cassette tape is seated or ejected and seated, the driving of the loading motor 1 is used to drive the deck, and its operation is simple and stable.
