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 are improved accordingly.

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.

Such organic coupling of many parts is problematic in that there are many defects in operation, practicality is low, and productivity is reduced by slowing down assembly work.

The present invention provides a locking member in one piece, the operation principle of which is to form a lifting piece that is raised together with the unlocking rod of the VTR, the tension bar (TENSION BAR) is orthogonal to the lifting bar through a diffraction table By forming the locking pieces at both ends and forming the supporting cylinders at both ends of the locking piece, the supporting cylinder is formed even if the lifting piece is raised for unlocking, so that the supporting cylinder is raised even if the lifting piece is raised for unlocking. Since the tension bar is rotated by the torsion action because the structure is adhered to the sole, the reeling state is released as the fine movement of the tip of the locking piece is attracted.

In order to maintain the relocking state, the torsional portion of the tension bar restores the elastic force as the release bar is lowered, and the resilient force maintains the relocking state to restrain the reel rotation by placing the fine grains of the locking pieces back between the reel gears. will be.

The above-described configuration and operation will be described in more detail with reference to the drawings.

According to the present invention, in the video tape cassette having an outer shape with the upper case 34 and the lower case 14, the foam 42 is formed in the outer direction toward the inner side of the locking member mounting wall 40 of the lower case 14, and the inner side thereof. In order to form the lifting pole 44 in a straight line position with the hole 26, the upper case 34, respectively, in the position corresponding to the foam 42 and the lifting foam 44, the Pole storage port 46 and the lifting Pole storage port, respectively (48), the reel locking member (50) is a symmetrical coalescing cylinder (52) fitted to the foam and the tension bar (56) for connecting the coalescing cylinder (52) through the locking piece (54), The drive bar 58 protruding forward from the center of the tension bar 56, the lifting hole 60 and the lifting piece 62 is attached to the lifting pole 44 is characterized by.

Reference numeral 40 in the drawings is a locking member mounting wall formed on the upper case.

4 is a configuration of the relocking member 50 according to the present invention, showing a symmetrical shape around the driving unit 58, the tip of the locking piece 54 is installed on the rear end of the coalescing cylinder 52 Locking fine grains 64 (SERIF) are formed, and the tension bar 56 has a characteristic of being manufactured in an inverted V shape so as to have excellent elasticity, as will be described later.

5 shows an application example of the present invention. After the upper case 14 is fastened to the lower case 34, the fouling container 46 is fitted to the warhead-type foul 42, so that the coalescing cylinder 52 is provided. Is possible to rotate in the sole 42, but the adhesion state is not lifted is maintained, except that the lifting hole (60) fitted to the lifting pole 14 is formed with a lower height as a predetermined height along the lifting pole 44 As well as being lifted, the lifting pole storage port 48 may also be formed to have the same outer diameter as the lifting pole 44, and the lifting hole 60 may be freely lifted and the lifting pole 44 is a warhead type. It should be in a state in which the foul storage port 48 is fitted.

Next, the operation of the present invention will be described.

First, the locked state is the same as in FIGS. 6A and 7A. At this time, the reeling member 50 is simply in the retracted state in which the lifting piece 62 is blocking the hole 26 because the reeling member 50 is fitted to the sole 42 and the lifting sole 44.

Now, when the release bar 25 of the VTR is raised to release the relocked state, the lifting piece 62 is raised by the lifting force, and the hatch 60 is guided while being inserted into the lifting hole 44. At the same time, the locking piece 54 should also be lifted together, but since the coalescing cylinder 52 is restrained from rising by the foul storage port 46 of the upper case 34, the tension bar 56 lifts up the driving unit 58. Will be subjected to torsion.

When a torsion occurs due to the rising of the tension bar 56, the tension bar 56 is pulled toward the lifting pole 44 of the tip fine grain 64 of the locking piece 541, and finally, the fine grain 64 is the gear of the reel ( The reeling release state deviating from 24) 24 'becomes, and thus, the free rotation (drive) of the tape reels 22 and 22' becomes possible.

In order to lock the tape reels 22 and 22 'again, the lifting piece 62 is lowered and restored by the elastic force of the tension bar 56 when the release bar 25 is lowered, and the tape is repeated by repeating the above process. The reel is locked and released.

As described above, the use of the present invention can improve the assembly and greatly reduce the number of parts, thereby reducing the cost and reducing the occurrence of defects during operation.
