The present invention relates to a lead lock (LiD Lock) flow device that is elastically installed between the tip rotational cover and the lower case of the magnetic tape cartridge loaded in the magnetic recording and reproducing apparatus to operate in accordance with the rotation of the rotational cover, in particular the magnetic Leads of the magnetic tape cartridge are smoothly and smoothly slidable between the lead lock and the lead spring, which are mounted inside the tip rotation cover of the tape cartridge, so that the rotation can be smoothly and smoothly without any wear on the upper locking piece of the lead lock. It's about a lock flow device.

In general, when the magnetic tape cartridge is loaded by the magnetic recording and reproducing apparatus, when the magnetic recording and reproducing apparatus is loaded, the head rotation cover is opened so that the head is wound and reproduced by a portion of the magnetic tape exposed to the outside of the cartridge by a predetermined length. On the contrary, when the cartridge is extracted to the magnetic recording and reproducing apparatus, the tip rotation cover of the magnetic tape cartridge is closed to protect the tape exposed to the cartridge tip by a predetermined length.

To provide this function, the rotating cover mounted on the tip of the magnetic tape cartridge is elastically installed with the lead spring and the lead lock. If necessary, the lead lock locks the rotating cover and then unlocks the magnetic recording / reproducing device again during playback. You need to open it with a pin. At this time, as the above operation is made, the interlocking operation is performed while the lead lock and the lead spring are slid between the magnetic tape cartridge front end pivot cover and the lower case, but is conventionally pivotally mounted to the front end of the magnetic tape cartridge 1. Resilient spring 6 having bent portions 4, 4 'at both ends and circular portion 5 at the center thereof as shown in FIG. One side bent portion (4) of the lead spring (6) and the engaging piece (7) having a sliding upper surface in a straight line integrally, and the locking projection (8) and the stopping protrusions (9) are integrated in the lower side. When the lead lock 10 is pivotally installed on one side of the lower case 3 'to assemble the upper case 3 and the lower case 3', the lead is elastically installed on one side of the rotation cover 2 and the upper case 3. One end of the bent portion 4 of the spring 6 is pivotally installed in the lower case 3 '. In contact with the straight upper surface of the lid lock 10, the upper engaging pieces 7 of the sleeping assembly is configured.

Therefore, when the magnetic tape cartridge 1 is loaded into the magnetic recording and reproducing apparatus or regenerated, the tip reversing cover 2 of the cartridge is rotated so that it is located on the straight surface of the upper locking piece 7 of the lead lock 10. One end bent portion 4 of the lead spring 6 that is in contact with each other is to be mutually slid. At this time, the upper end surface of the lead lock 10 is flat, the one end bent portion 4 of the lead spring 6 is angled The ends cut while being cut are formed with minute protrusions that are invisible, and as they slide together, the upper surface of the upper locking piece 7 of the lead lock 10 is scratched, so that a pie is generated, so that the contact between the lead lock and the lead spring is as much as that. In addition to not only smoothing the movement, noise caused by scratching and abrasion was generated while sliding, and in particular, the magnetic recording to reproduce the magnetic tape cartridge because the contact operation was unnatural. The function of the reproducing apparatus was also adversely affected, and the quality of the magnetic tape cartridge itself was also deteriorated and the life was shortened.

The present invention compensates for the above-mentioned drawbacks as described above. The lead spring and lead spring slid between the tip rotation cover and the upper and lower cases of the magnetic tape cartridge are formed in a circular shape. The upper surface of the engaging piece is to form a round portion as described in detail by the accompanying drawings as follows.

In the construction of the present invention, as shown in FIG. 1, the upper cover 2 of the magnetic tape cartridge 1 and the inner side of the rotating cover 2 mounted at the tip of the lower case 3, 3 'is rotated inward. The lead spring (10) and the lead spring (6) are elastically installed with the lead lock (10) and the lead spring (6) to link the operation of the pivoting movement. The other end of the lead spring (6) inserted into the upper case (3) is touched inside the pivoting cover (2) to form a rounded portion (11) as shown in FIG. The rotating cover 2 and the lead spring 6 are formed by forming a round part 12 on the upper surface of the upper locking piece 7 of the lead lock 10 which is slid with the part and is installed on one side of the lower case 3 '. ) Is fixed to the upper case (3) assembled in the lower case (3 ') as shown in Figure 3 the upper cover (3) 2) the circular end 11 of the other end of the lead spring 6 which is supported with the upper end of the upper locking piece 7 of the lead lock 10 inserted into the lower case 3 'is brought into contact with the round part 12 of the upper surface. It is assembled.

Referring to the effect of the present invention is assembled as described in detail as follows.

Normally, the tip rotation cover 2 of the cartridge 1 is opened and closed when the magnetic tape cartridge 1 is regenerated and loaded or extracted into a magnetic recording / reproducing apparatus (not shown). While locking and unlocking 2), the lead lock 10 is also rotated together.

As the lead lid 10 rotates, as shown in FIG. 4, the circular end portion 11 of the lead spring 6 in which the upper round portion 12 of the upper locking piece 7 is in contact with the sliding member is slid. .

Therefore, the end portion of the lead spring 6 becomes a circular portion 11, and the upper end of the upper locking piece 7 of the lead lock 10 is also formed of a round portion 12, so that the contact of both ends is in contact with the point contact Since the operation is made while the contact operation is made to be quite smooth and smooth.

Therefore, since the upper surface of the engaging piece 7 of the upper end of the lead lock 10 and the end bent portion 4 of the lead spring 6 do not slide and are not scratched or dug, the operation is smooth and smooth. It is possible to eliminate the noise and to make the contact operation very smooth, so that it does not adversely affect the recording device of the magnetic tape cartridge, and also improves the quality of the magnetic tape cartridge and extends the life. .
