The present invention relates to a relocking member for locking a tape reel of a video tape cassette, and more particularly, to a relocking member in which a reel locker is formed of a single unit having elastic force and the peripheral shape and structure thereof are improved.

As shown in FIG. 1, the relocking member has reelers 10, 10 'and release levers 12 attached to the soles 16, 16' and the support 18 of the lower case 14, respectively. , The locker portions 20 and 20 'of the reel lockers 10 and 10' are hooked to the gears 24 and 24 'of the tape reels 22 and 22' which make up the winding reel. The locking state is maintained to prevent the rotation of the tape reel accordingly, and the unlocking state is released as the release bar 25 of the VTR (not shown) pushes the release lever 12 through the hole 26. Is rotated about the hinge shaft 28, the lifting piece 30 of the release lever 12 rotates the rotating pieces 32, 32 'of the locker 10, 10', which is a locker. By separating the parts 20 and 20 'from the gears 24 and 24', the tape reels 22 and 22 'can be rotated.

However, in the conventional relocking member, as shown in FIGS. 1 to 3, the revolver 10, 10 ′ and the release lever 12 support and rotate the support 16, 16 ′ and the supporter ( 18) is formed, and the peripheral configuration according to the complicated shape is difficult to manufacture and assembly process, as well as the relocker (10, 10 ') is always a tape reel 22, 22' Since the elastic member must be provided to have the elastic force to prevent the increase of the manufacturing cost due to the excessive number of parts.

The organic combination of these components has many problems in terms of operation defect, less practicality, and slowing down the assembly work, thereby lowering productivity.

The present invention provides a monolithic relocking member, which is supported by a poe on an existing lower case, and its members are pulled out of the tension bar when the sliding surface is advanced by the relocking release rod, and both ends of the tension bar. The locking rotating piece formed at the center is spaced apart from the gear of the tape reel while being rotated to release the locked state.

When the relocking release rod is returned to its original position, the rotating piece is also reduced by the elastic force of the tension bar, and is inserted again between the gears of the tape reel to maintain the relocking state.

Therefore, bar can contribute to the assembly and cost reduction by the simplification of parts, the present invention will be described in more detail with reference to the accompanying drawings.

The present invention is a relocking member of a video tape cassette, in which a vertical cylindrical portion 50 is symmetrically connected to a tension bar 52, and a sliding portion 54 at the center of the tension bar 52 has a vertical surface 62 and an inclined surface. It is composed of 58, the cylindrical portion 50, the locking piece 60 is formed of a vertical surface 62 and the bending surface 64, the relocking of the lower case 14, the relocking member is installed The member 68 and the guide wall 70 are installed in the member mounting wall 66, and the guide wall 70 'of the pole storage 68' is provided in the reeling member mounting wall 66 'of the upper case 34. ) And a guide wall 70 'and a reel locking member separation preventing rib 72 are formed.

4 is a block diagram of the relocking member 40 according to the present invention, and shows a structure in which the left and right are symmetrically formed around the sliding part 54. As described below, the tension bar 52 is an elastic body having good restoring force.

FIG. 5 shows a part where the upper locking part 34 and the lower lower case 14 of the video tape cassette in which the receptive locking member 40 is installed are separated, and the receptive locking member is installed.

Here, the relocking member mounting walls 66 and 66 'are the same as the conventional positions of the guide walls 70 and 70', and only the positions of the pole 68 and the pole storage 68 'are guide walls 70 ( 70 ').

In particular, the upper end of the pool 68 is an ampule (AMPULE) shape, the fool storage port 68 ′ is grooved to be inserted so that the upper end of the ampoule-shaped pool 68 is unevenly coupled.

Therefore, according to the assembly process of a general video tape cassette, when the receptacle locking member 40 is also assembled with the cylindrical portion 50 fitted to the pole 68 of the lower case 14, covering the upper case 34, The assembly is made to prevent the separation by the rib 72.

The state diagram after completion of the assembly is shown in FIG.

Next, the operation of the present invention will be described with reference to FIGS. 6 and 7.

The state after assembling in which the reel-locking member 40 is installed is the same as that of Fig. 7a, so that the SERIF tip of both bent surfaces 64 is between the gears 24 and 24 'of the tape reels 22 and 22'. (Locked state).

At this time, the sliding portion 54 is in a planar position where the inclined surface 58 is covered with the hool 26, and in order to release the relocking state, as shown in FIG. When raised through the first contact with the inclined surface 58 inside.

When the release bar 25 is further raised, the inclined surface 58 is pulled to the dotted line position, and the cylindrical portion 50 must also be pulled, but it is rotated about the pool 68 because it is fitted in the pool 68.

This rotation of the cylindrical portion 50 also rotates the locking piece 60 to disengage the bent surface 64 from the gears 24 and 24 'as shown in FIG. 7B, and thus the tape reels 22 and 22'. Becomes the unlocking state in which rotation is enabled. In order to achieve the relocking state, the tension bar 52 is restored while the release bar 25 is lowered to reduce the state to the state of FIG. 7a.

As described above, the present invention can be achieved by using a relocking member having a sliding part, but also having a simple configuration but smooth operation and no malfunction.

In addition, the assembly of the components can be improved with a simple cost reduction effect.
