The lock case moves by the release device and the elastic piece, There is an advantage that theft of the protective case including the information recording medium having a small volume can be prevented as much as possible. Particularly, the above advantages are achieved in a single display case.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view showing a configuration of a display case to which the present invention is applied. The display case 20 for storing and displaying the protective case 10 including the viewing medium is formed in a single rectangular tube shape. .

The display case 20 forms a storage space 21 having a size large enough to store the protective case 10 including the information recording medium therein.

An opening 22 for entry and exit is formed on one side of the shelf case 20 forming the storage space 21 with a width larger than that of the protective case and the other side of the shelf case 20 The protruded portion 24 is formed in a size such that a finger for guiding the protective case is easily inserted into the protruded portion 24, and a through hole 25 for exposing the antitheft circuit of the protective case is formed around the protruded portion.

In order to prevent detachment of the protective case housed in the accommodating space 21, the escape preventing pieces 23 are formed by intercepting each corner of the opening 22.

2 is a sectional view taken along the line AA in Fig. 1, and Fig. 3 is a sectional view taken along line BB in Fig. 1, in which the storage space 21 of the display case is formed to have a size sufficient to accommodate the protective case 10, (22) is formed at a height smaller than the height of the protective case.

A locking means (30) for locking and unlocking the stored protective case is provided between the inside of the storage space (21) and the outer surface of the display case.

4 is an exploded perspective view of the locking means of the present invention. The locking means 30 includes a locker 31 which moves in a vertical direction in the storage space 21 and makes contact with the outer surface of the protective case in a non-contact manner, A guide shaft 32 integrally projecting from the housing space 21 and passing through the rim of the housing space 21 to receive the movement force from the outer surface of the outer display case, And the other end of the elastic piece 34 is fixed so that the guide shaft 32 and the elastic piece 34 are hidden from each other, As shown in Fig.

A locker 31 which moves in a vertical direction in the storage space 21 and makes contact or noncontact with the outer surface of the protective case as shown in FIGS. 11 to 12 when the lock means 30 is implemented; A guide shaft 32 which penetrates the rim of the housing space 21 and receives a moving force from a portion protruding from the outer surface of the case, and a pair of recessed both sides of the locker to secure the movement control of the locker A pair of resilient pieces 34 that are free to be inserted into the lock grooves 33 or separated from the lock grooves 33 and a pair of resilient pieces 34 that are separated from the resilient pieces 34, And a cap body 35 which is stably fused to the display case.

In one embodiment of the above-described display case, one side of the display case 20 is cut out for the entrance and exit of the protective case 10 including the information recording medium as in the configurations of FIGS. 7 to 10 An opening and closing plate 26 for opening and closing the opening 22 and an opening 22 formed by punching out the inside surface of the accommodating space 21 so that the opening and closing plate 26 can slide the opening of the opening 22 And a locking means 30A which is installed vertically at the end of the opening and closing plate 26 to prevent storage and theft of the protective case by engaging and disengaging the display case.

The locking means 30A includes a coupling protrusion 29 having a lock hole 28 protruding from the periphery of the opening 22 of the display case 20 and thermally fused to the upper surface of the cover plate 26 A guide shaft 32A which moves toward the lock hole 28 of the coupling protrusion 29 in the inside of the cap body and a guide shaft 32A which moves in the direction of the lock hole 28 of the guide shaft 32A, A resilient piece 34 for controlling the movement of the guide shaft 32A by its own resilience and the magnetic force of the release device and a cap body 35 for concealing the resilient piece 34 of the guide shaft 32A.

When the protective case 10 including the information recording medium is to be stored, the position of the locker of the locking means is checked and moved to the unlock position, The protection case 10 including the protection case 10 is inserted into the storage spaces 21 and 21 of the display case 20 and then the upper end of the protection case is vertically installed, (21).

When the portion of the guide shaft 32 protruding to the outer surface of the cap body 35 is pushed as shown in FIG. 6a, the guide shaft 32 moves and the locker 31 comes into contact with the rim surface of the protective case 10, The other side of the protective case 10 is brought into contact with the upper surface of the storage space 21 by moving the case 10.

At this time, each corner of the protective case 10 is clogged with the escape preventing pieces 23 located at the corners of the opening 22 of the storage space 21, and the locking grooves 33 formed in the guide shaft 32 of the locking means Since the free end of the resilient piece 34 controls the lock groove in a state that the free end of the resilient piece 34 crosses, the locked state of the protective case is maintained.

When at least one elastic piece 34 is provided in the locking means 30, it is preferable that at least one of the locking grooves 33 formed on both side surfaces of the guide shaft 32 is formed, The control of the guide shaft 32 is further stabilized by the lock groove 34 and the lock groove 33. [

When the manager or the owner intends to sell or rent the information recording medium in a state where the protective case 10 is stored in the storage space 21 of the display case, the display case 20 is brought to the checkout counter, The cap body 35 of the display case 20 is also inserted into the release device 50,

Therefore, when the elastic piece 34 provided in the cap body 35 is released from the lock groove 33 in a state of being moved toward the permanent magnet by the magnetic force of the permanent magnet 51 of the release device 50, The lowering action is effected by its own weight, and at the same time, the load of the protective case 10 is added, so that the downward movement is smoothly performed and the locker is released.

When the locking means is released as described above, the corner of the protective case 10 is located below the upper side release preventing piece 23 of the opening 22 of the display case 20, The upper edge of the protective case 10 is pulled out of the opening 22 while being inclined in the accommodating space 21 so that the lender pulls the upper end of the protective case 10 The protective case 10 including the information recording medium from the inner display case 20 can be completely separated and rented or sold.

The buyer or the lender may attempt to release the locking means by bringing an object having magnetic force into close contact with the periphery of the locking means of the protective case for the purpose of cutting off the protective case including the information recording medium. Since the resilient piece is provided in the form of a free beam and is provided with a dual structure, it is not easy to release the locking means without using the releasing device provided at the counter, so that the economic loss due to the loss can be maximized .

The display case of the present invention in which the locked state is released by the magnetic force emitted from the permanent magnet of the lock device and the load of the locker can be stored and taken out from the storage space itself, There is an advantage in that theft of the information recording medium is prevented because the risk of breakage is small and the damage to the information recording medium is difficult depending on the material characteristics.

The same effect will be obtained in the configuration according to another embodiment of the present invention.

That is, when the cover plate 26 is inserted into the guide hole 27 with the protection case 10 including the information recording medium inserted into the storage space 21 of the display case 20, When the guide shaft 32 that is closed and protruded to the cap body 35 is pressed, the state is such that it is inserted into the lock hole 28 of the coupling protrusion 29 formed at one side of the opening 22. At the same time, The distal end of the guide shaft 32 does not protrude from the upper surface of the cap body 35. In this state, the distal end of the guide shaft 32 does not protrude from the upper surface of the cap body 35 It is not easy to artificially separate the cover plate 26 from the display case 20. In order to release the lock state, a separate release device provided on the counter should be installed in the cap body 20 35, the resilient piece 34 is attracted to the magnetic force emitted from the permanent magnet 51 of the releasing device 50 To be out of the lock groove 33 of the guide shaft (32).

At this time, since the locker 31 is in an inverted state, the locker 31 is moved downward by its own weight and is separated from the lock hole 28 of the coupling protrusion 29, thereby becoming unlocked.

When the lock body is unlocked as described above, when the cap body welded to the upper portion of the cover plate 26 is pulled out, the opening 22 of the display case 20 is opened, (10) can be taken out.

In another embodiment of the present invention, the display case is provided with a storage space in the form of a rectangular tube, and is provided with a guide shaft that performs locking and unlocking while moving in the vertical direction. It is possible to obtain the same operational effect.

The present invention is not limited to the above-described configuration and can be applied to similar anti-theft rental and display cases.
