It is made of a spring 44 to be in close contact with the).

The following describes the loading process and the eject process of the operating state of the present invention configured as described above.

First, as shown in the operating state for loading, when the cassette tape (T) is pushed into the deck as shown in Figure 3 so that the front end surface of the cassette tape (T) is in contact with the supporting piece (21c) of the hook member (21) At the same time, the hook 21b of the hook member 21 is caught by the inner circumferential portion of the reel r of the cassette tape T, and when a little more force is applied in this state, the hook member 21 is reversed. The driven lever 22 rotates slightly.

When the driven lever 22 is slightly rotated, the rear end 22d turns on the micro switch 24 so that the motor 31 is driven. When the motor 31 is driven, the connecting gear 33 rotates through the plurality of reduction gear sets 32, and when the connecting gear 33 rotates, the protruding pin 33a on the upper surface of the loading operation member 12 Since the loading operation member 12 is moved in the advancing direction (rightward direction in the drawing) because it is fitted in the elongated piece 12d of the elongated hole 12c.

Advancing of the loading actuating member 12 is stopped when the omission 33c of the connecting tooth 33 is located on the deceleration tooth set 32, which should be the point at which the advancing of the loading actuating member 12 is completed. .

As such, when the loading operation member 12 moves forward, the driven lever 22 is first rotated to completely pull out the cassette tape T.

That is, since the protruding piece 12e formed on the upper side of the loading operating member 12 is fitted in the recess 23b of the drive lever 23 condensed at the hinge point 22, with the advancement of the loading operating member 12, As the driving lever 23 rotates, as the driving lever 23 rotates, the driven lever 22 bound by the extension protrusion 23a rotates, and the hook member 21 rotates by the driven lever 22. Backwards along the sliding incision groove 13c of the member 13, and finally, the hook member 21 has a cassette tape T because the hook 21b is caught in the inner circumference of the reel r of the cassette tape T. Can be pulled in completely.

On the other hand, when the loading operation member 12 completes the reverse, the rotating member 13 and the elevating member 14 descends along the elevating grooves 12a and 12b before and after to complete the loading.

That is, the rotation member 13 rotates downward with the advancement of the loading operation member 12 because the projection piece 13b formed on the front side thereof is fitted in the rear lifting groove 12a of the loading operation member 12, At the same time, the elevating member 14 is also lowered downward with the advancement of the loading operating member 12 because the protrusion piece 14c formed as a side piece is fitted in the front lifting groove 12b of the loading operation member 12. The member 14 is connected to the elevating member 14 and the rotating member 13 so as to be mutually flowable to the raised piece 14b and the connecting piece 13d of the upper surface, and lowered while maintaining the horizontal state without tilting the cassette. The tape T is loaded to the position of the head (not shown).

This is the loading process, and the following describes the eject process.

The interlocking lever 42 is rotated by pressing the rear end 43b of the N-shaped lever 43 provided to be rotatable on the main frame 11.

Therefore, since the tip 43a of the N-shaped lever 43 rotates by winning the force of the spring 44, the lower end of the connecting tooth 33 is caught by the ratchet jaw 33b of the connecting tooth 33, and the connecting tooth 33 is rotated in the reverse direction. Rotate it slightly.

By the operation of the L-shaped lever 43, the connecting gear 33 can be engaged with the reduction gear set 32 again, and the connecting gear 33 which rotates in reverse causes the protruding pin 33a on the upper surface thereof to make a long hole ( The extension piece 12d of the loading operation member 12 in which the 12c is formed can be retracted again, and the retraction of the loading operation member 12 raises both the lifting member 14 and the rotation member 13.

That is, since the elevating member 14 and the projection pieces 13b and 14c of the rotation member 13 are fitted in the elevating grooves 12a and 12b before and after the loading operation member 12, the loading operation member 12 With the retraction of the lifting member 14 is raised to unload the cassette tape (T).

On the other hand, when the cassette tape T is raised, the protrusion 12e formed on the upper side of the loading operation member 12 rotates the driving lever 23 in the opposite direction, so that the driven lever 22 also moves in the opposite direction. Will be rotated.

The reverse rotation of the driven lever 22 advances the hook member 21 connected to the front end 22b, and the hook member 21 forwards the cassette tape T supported by the support piece 21c to the front. It can be pushed out, and part of the cassette tape (T) is exposed to the outside of the deck so that the user can take it out.

The following describes another embodiment of the present invention according to FIG.

7 is an embodiment in which the structure of the loading operation member and the connecting tooth of the present invention is changed.

Here, the second loading operation member 12 forms a U-shaped opening 12f in the extension piece 12d, and then, on both inner surfaces of the opening 12f, the forward rack 12g and the reverse rack 12h, respectively. And the second connecting gear 33 form a pinion 33d on the upper surface thereof, but have teeth in only a part of the teeth, so as to alternately contact the forward rack 12g and the reverse rack 12h. It is to be possible.

In addition, the second N-shaped lever 43 may be in contact with the ratchet jaw 33b formed on the bottom surface of the second connecting tooth 33, but is formed in a c-shape.

As shown in FIG. 8, the operating state of this embodiment is that when the motor 31 is operated and the second connecting gear 33 rotates, the pinion 33d on the upper surface thereof moves forward of the second loading operating member 12. 12g), so that the second loading operation member 12 is advanced so that the cassette tape T can be loaded in the same manner as in the above-described embodiment, and the omitted portion 33c of the second connecting tooth 33 is also provided. Rotation can be stopped.

On the contrary, when performing the ejection process, as shown in FIG. 9, the eject lever 41 rotates the interlocking lever 42, and the interlocking lever 42 presses the rear end 43b of the second L lever 43. 43a pushes the ratchet jaw 33b on the bottom face of the second connecting tooth 33 in the rotational direction so that the teeth on the outer circumferential surface deviate from the omission 33c.

In this way, when the second connecting gear 33 is rotated, the pinion 33d on the upper surface of the second connecting gear 33 comes into contact with the backward rack 12h so that the second loading operating member 12 can be retracted. As in the embodiment, the cassette tape T can be ejected.

In the present invention as described in detail above, the cassette tape is inserted into the deck to push the support piece 21c of the hook member 21 only slightly, and then the micro switch 24 drives the motor 31. As it is automatically loaded, it works very smoothly and smoothly. Also, when ejecting the cassette tape (T) again, the product value is greatly increased by using the power of the motor instead of pressing the eject lever with force as in the prior art. There is an advantage to be improved.
