The present invention relates to a cassette holder locking device of a tape recorder.

Tape recorders that perform recording / playback operations on magnetic tapes, such as a video cassette tape recorder (VCR), a camcorder, a digital audio tape recorder (R-DAT), and the like, include a cassette holder in which a tape cassette is stored; A cassette holder locking device is provided for seating and fixing the cassette holder on the deck.

1 to 4 show such a cassette holder locking device, which is a cassette holder locking device proposed by the inventor (Korean Patent Application No. 95-54732).

Referring to the drawings, the cassette holder 200 is mounted on the deck 100 having the left and right side chassis 101 and 102 to be liftable, and the tape cassette T is accommodated in the cassette holder 200 to accommodate the deck 100. It will be seated on the reel table (104, 105) provided on the.

On both sides of the cassette holder 200, a pair of arm members 210 and 220 are rotatably cross-coupled with each other, and by one arm member 220 and a spring 202 of the pair of arm members. An interlocking member 260 coupled to be elastically biased is provided. Accordingly, when the cassette holder 200 is pushed down toward the deck 100 by applying an external force, the spring 202 is tensioned and rotated in a direction in which the arm member 220 and the interlock lever 260 are spaced apart from each other. When the grip and the external force are removed, the cassette holder 200 is lifted up again by the elastic restoring force of the spring 202.

Therefore, as the locking means for locking the cassette holder 200 on the deck 100 and not being lifted again, a structure as shown in FIG. 3 is employed. That is, the fixing plate 310 is fixed to the side chassis 102 of the deck 100 and a plurality of guide pins 311 and 312 are formed, and the operation member 313 rotatably coupled to the fixing plate 310. And a locking member 315 slidably coupled to the fixed plate 310.

The operating member 313 has an inclined surface 313a inclined at a predetermined angle on one side surface and a vertical surface 313b extending vertically from the inclined surface 313a. Guide locking holes 315a and 315b slidably coupled to the guide pins 311 and 312, and the interlocking piece slidably contacting the inclined surface 313a and the vertical surface 313b to the locking member 315. 315e and a locking piece 315d to lock the fixing pin 222 formed on the arm member 220 of the cassette holder 200, and the operating member 313 and the locking member 315 are formed. It is connected to the mutual spring member 314.

As the holder 201 is lowered, when the fixing pin 222 protruding from the side of the arm members 210 and 220 presses the locking piece 315d, the locking member 315 is moved to one side. As the fixing pin 222 is moved and the locking member 315 is restored by the spring member 314 at the same time, the fixing pin 222 is locked to the locking piece 315d.

Meanwhile, a release piece 315c extending to the locking member 315 and bent downward is formed. The disengagement piece 315c rotates in conjunction with a predetermined cam gear 400 positioned under the reel table 105 in the eject mode, as shown in FIG. 4. In contact with the front end portion 501 of the lock member 315 is moved in the direction of the drum (D) of FIG. Accordingly, the locking of the fixing pin 222 hanging on the locking piece 315d is released, so that the cassette holder 200 is elastically raised.

By the way, as described above, the previously proposed cassette holder unlocking device has an advantage of performing locking and unlocking of the cassette holder with a simple structure, but there is a possibility that an unwanted unlocking operation may occur when there is a severe impact from the outside. There is this.

Accordingly, an object of the present invention is to provide a cassette holder locking device of a tape recorder whose structure is improved so that an unwanted unlocking operation does not occur even against an external impact.

In order to achieve the above object, the present invention provides a cassette holder locking device for seating and fixing a cassette holder on which a tape cassette is accommodated. An arm member; A fixing plate fixed to one side wall of the deck; An actuating member rotatably supported by the fixing plate and having an inclined surface inclined at a predetermined angle at one end and a vertical surface formed in a direction perpendicular to the end of the inclined surface; A locking member slidably coupled to the fixed plate and having a locking piece for resiliently locking the interlocking piece interlocked with the inclined surface and the vertical surface and an upper fixing pin and a release piece for releasing the locking state of the locking piece; A spring member which connects the other end of the actuating member and the locking member to elastically attract each other; A cam gear installed in the deck and having a protrusion for rotationally driving by a motor to interlock the release piece; A main slide member reciprocating from the cam gear; And a rotating plate interlocked with the main slide member to selectively press the locking member in one direction.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment according to the present invention will be described in detail.

First, the cassette holder locking device of the present invention also has a cassette holder in which a tape cassette is accommodated, which can be lifted and mounted on a deck. A cassette holder locking means is provided for locking and unlocking the holder.

The deck is provided with a conveying means for compressing and transferring the magnetic tape together with the axis of the rotating motor. As shown in FIG. 5, the review arm 340 and the pinch arm 350 are provided on the rotating shaft provided on the deck. ) And the linkage arm 360 are sequentially rotatably coupled.

The review arm 340 is provided with first and second guide poles 341 and 342 driven by a magnetic tape, and the pinch arm 350 is pressed against a shaft of a rotating motor as described above. A pinch roller 351 for attracting is provided. In addition, a protrusion 351 protruding in a plane is formed on one axis of the pinch arm 350.

As shown in FIG. 6, the transfer means is interlocked with the main slide member 120 moved by the cam gear 400 to rotate on the deck.

When the conveying means is rotated in this way, as shown in FIG. 7, the protrusion 351 is in contact with the pressing of the rear surface of the fixing member 315 described above in the direction of the arrow (A).

Therefore, the fixing member 315 is not pushed back against the impact from the outside.

The cassette holder locking device of the present invention as described above is as follows.

1 and 7, when the tape cassette is seated on the reel tables 104 and 105, the locking pin 222 presses the locking piece 3156 as the cassette holder 200 is lowered. As a result, the locking member 315 is slightly moved toward the drum D of FIG. After that, if the cassette holder 200 is continuously lowered, the locking member 315 is restored to its original position by the elasticity of the spring 314 and the fixing pin 222 is locked to the locking piece 315d.

When the locking of the cassette holder by the locking member is completed as described above, the main slide member (FIG. 6; 120) is driven as described above, and the transfer means, that is, the review arm 340 and the pinch arm 350 and The linkage arm 360 is rotated. This operation is performed simultaneously with the operation of loading the magnetic tape in the tape cassette onto the head drum (FIG. 1D).

When the conveying means is rotated in this way, as shown in FIG. 8 schematically, the protrusion 352 of the pinch arm 350 presses the fixing member 315 in the locking direction A. FIG. .

Therefore, even when an external shock is transmitted, since it is firmly supported by the protrusion 352, an unwanted unlocking phenomenon does not occur.

Meanwhile, in the present embodiment, the protrusion 352 is formed on the pinch arm 350. However, the protrusion 352 may be selectively applied to a member rotated in conjunction with the main slide member 120, such as the review arm 340. Of course.

Therefore, the cassette holder locking device of the tape recorder according to the present invention is provided with a rotating member as described above as a safety means for preventing the locking from being released again after the cassette holder is seated and locked on the tech. In addition, it is possible to stably play and record functions and to improve the reliability of the product.

The present invention is not limited to the above described and illustrated in the drawings. It goes without saying that more modifications or variations are possible within the scope of the following claims.
