The present invention relates to a tape cassette loading apparatus of BCAL, and more particularly, to a tape loading apparatus that can be doped and unloaded with a tape loading motor without using a dedicated motor for tape cassette loading.

In the conventional VCA tape cassette loading device, as shown in FIG. 1, both side guide plates 2 which are placed in parallel with each other with a width larger than the width of a tape cassette (hereinafter referred to as a cassette) on the base plate 1 are shown. The driving force of the dedicated driving motor 3 for the cassette loading fixed to (only one side is shown in the drawing) is connected to the wheel gear 5 through the worm 4, and the coaxially connected connecting gear 6 has an arm gear. (7) is connected to the arm gear (7) has a long hole (8) is formed between the high hole (11) of the carrier (10) containing the cassette (9) between the long hole (8) is inserted "a" guide Sliding to the ball 12 is to be able to reciprocate.

In this conventional cassette loading device, the high-speed 11 fixed to the carrier 10 pushes the long hole 8 of the arm gear 7 by pushing the cassette 9 into the carrier 10 and the arm gear. (7) rotates and accordingly the fixed projection 12 of the arm gear (7) is rotated so that the movable piece 14 of the switch 13 is separated from the lower fixing piece (15) by the electric signal drive motor (3) ) Rotates so that the gear 9, the connecting gear 6, the arm gear 7 and the like rotate in the direction of the arrow shown in FIG. 1A, and the cassette 9 is loaded and the projection 12 of the arm gear 7 is rotated. ') Pushes the movable piece 14 of the switch 13 to contact the upper fixing piece 15' like the 1b diagram, and the loading is completed for the electrical signal.

When ejected from the loading position, the action is reversed.

However, such a conventional cassette loading device is separated from the drive source of the deck assembly, and since a separate dedicated motor for cassette loading was required, there was a separation point in which the unit cost was increased.

The present invention has been devised to solve such a conventional defect, and the cassette can be loaded by connecting the rotational force of a cam gear that is rotated by the power of the tape loading motor to the cassette loading device in the loading and ejecting modes. After the loading is completed, the power transmission is to be cut off, which will be described in detail with reference to FIGS. 1 to 6.

In the drawing, 1 is a base plate, and a cam gear 18 having a cam groove 18a is fixed to the fixed shaft 17 of the lower bracket 16 of the base plate 1, and the base plate 1 is fixed. The shaft 19 has a double-sided gear 20 having gears 20a and 20b formed on the inner and outer circumferential surfaces thereof, and a shanghai heavy gear 22 having a rotating plate 21 and upper and lower shaft gears 22a and 22b. The lower gear 22b of the double gear 22 is meshed with the cam gear 18, and the relay gear 24 is fixed to the fixed shaft 23 of the rotating plate 21, so that the relay gear 24 is engaged. Is meshed with the inner gear 20a of the double-sided gear 20 and the upper gear 22a of the double gear 22.

In addition, the worm 26 having the spur gear 35 on the lower side of the cassette loading device portion is rotatably compressed to the shaft 27, and the spur gear 25 is the outer gear of the double-sided gear 20. 20b).

Meanwhile, the locking lever 29 and the cam lever 30 are fixed to the fixed shaft 28 of the base plate 1, and a torsion spring 31 is interposed between the levers 29 and 30. 29, an insertion groove 29a into which the lower end of the shaft 23 of the relay gear 24 is inserted and a mirror surface 28b are formed at both sides thereof, and an operation pin 30a fixed to the front end of the cam lever 30. The cam gear 18 is inserted into the cam groove 18a.

In the drawings, reference numeral 31 denotes a supply reel table, 32 a winding reel table, 33 shows a function folate, 34 shows a pinch roll, and 35 shows a pinch roll lever. Is indicated.

The present invention as described above, when the user pushes the cassette 9 into the carrier 10 in the cassette loading and ejecting mode, the movable piece 14 and the fixing pin 15 of the switch 13 are rotated by the rotation of the arm gear 7. With this drop, the tape loading motor turns the cam gear 18 clockwise in FIG. At this time, the displacement of the cam groove 18a does not change. Therefore, the cam lever 30 is stationary and the locking lever 29 is pushed in the direction of the arrow by the restoring elasticity of the torsion spring 31, but is no longer serious by the stopper 36. On the other hand, since the cam gear 18 meshes with the lower gear 22b of the double gear 22 to rotate the double gear 22, the double gear 22 meshes with the relay gear 24 to rotate the relay gear 24. . At this time, the rotating plate 21 rotates about the fixed shaft 19, and when the lower end of the fixed shaft 23 hits the locking lever 29, the locking lever 29 is the torsion spring 31 ) While rotating while entering the insertion groove (28a) of the locking lever 29 can not rotate anymore. At this time, since the relay gear 24 meshed with the inner shaft gear 20b of the double-sided gear 20 rotates about the fixed shaft 23, the double-sided gear 20 rotates and the spur gear 25 on its outer shaft 20b. Rotate the worm 26 blocked.

As such, when the worm 26 rotates, the wheel gear 5 engaged thereto rotates, and then the loading operation proceeds in the same manner as in the prior art.

On the other hand, in a mode other than loading, the displacement of the cam groove 18a of the kimgear 18 is changed so that the locking lever 29 is rotated in the clockwise direction as shown in FIG. 4b to release it from the relay gear 24 and the insertion groove 29a. Since the relay gear 24 and the rotating plate 21 do not rotate the double-sided gear 20, power to the cassette loading device is cut off and other modes can be performed.

In the case of ejecting the cassette in the regeneration mode, as the kimgear 18 is rotated in the reverse direction, when the locking lever 29 is brought to the fourth state by the displacement of the cam groove 18a, the fixed shaft of the rotating plate 21 is rotated. Since the 23 pushes the inclined surface 29b of the locking lever 29 and enters the insertion groove 29a to rotate in the fixed position of the relay gear 24, the double-sided gear 20 and the worm 26 are Rotation in the reverse direction ejects the cassette 9.

As described above, the inventive cassette loading apparatus eliminates a dedicated motor for cassette loading and uses a tape loading motor in common to load and retract the cassette, thereby contributing to the cost reduction of the product.
