Invention Explanation ($) The block 2 1 is locked in the recess 20 by a key lock 2 2. In the same manner, a recessed portion 23 is provided in the recessed plane 12, and a block 24 matching the recessed portion 23 is provided in the recessed portion 23. The block 24 is provided by a key The lock 25 is fixed inside the recessed portion 23, and the top surface of the block 24 is flush with the recessed plane 12. In the case where the blocks 2 1 and 24 are inserted and locked in their respective recesses 20 and 23, respectively, the opening tool can be accessed at any time. The tool is illustrated in Figure 1 and Figures 4 and 5. • An anti-theft device 26 such as that shown in FIG. 4 is disclosed in, for example, patents EP — B1 — 0451189, EP — B1 — 0 5 8 1 8 1 1, and EP — B1 — 062088 8 Among them, such an anti-theft device includes a frame 27 for accommodating a CD disc or a video cassette in its inside. A magnetic latch 28 protrudes from the frame, which directly or indirectly prevents the anti-theft device from being removed from the cassette. When separating the cassette and the anti-theft device, push down the anti-theft device with the cassette in the direction of arrow A against the opening tool and be introduced into the magnetic latch inside the recess 15 The lock engages the permanent magnet 16 and the permanent magnet 16 introduces the latch into the open position. The anti-theft device can then be removed from the card case. In order to cooperate with the magnetic latch 28, the permanent magnet 16 in the recess is installed in an inclined position, but for other magnetic latches, the permanent magnet can also be installed in a horizontal position. A better way is to allow the permanent magnets to be applied to a Chinese paper standard (CNS) A4 (210 X 297 mm) when the magnetic latch is engaged with the permanent magnet. --- 1τ --------- Green (Please read the notes on the back before filling out this page) Intellectual Property Bureau, Ministry of Economic Affairs, Consumer Cooperation Du printed 46〇654 A7 B7 V. Description of Invention (t) A biasing mechanism is pressed against. This biasing mechanism can be a spring ', but in the preferred embodiment, a biasing force is provided by such a magnet as the biasing mechanism. The magnet 16 is attracted to the metal frame 1 4' but by setting A divider in the recess 15 separates it from the metal frame »* 〇 If, instead, considering the use of an anti-theft device 29 as shown in Fig. 5, such an anti-theft device is disclosed, for example, in a patent case EP-A 2 — 0508201 and EP-B10712460, the anti-theft device includes a frame 30 and a magnetic latch inside the side edge surface 31 of the frame. At this time, the opening tool The parts located on the surface 1 2 will be used. The magnetic latch may include a metal tongue that accepts magnetic force or two such metal tongues that are spaced apart from each other along the longitudinal direction of the side edge surface. The positions of the magnets 17 and 18 can be such that when the side edges of the anti-theft device are moved above the surface 12 in the direction of arrow B and the anti-theft device is engaged with the shoulder 13 and the junction 19 (If only one metal tongue key is provided), the metal tongue key will be paired with one of the magnets 17 and 18; if two metal tongue keys are provided, each metal tongue key will be separately with the magnet 17 Pair with one of 1 8. With the position of the anti-theft device, the magnetic latch is guided to the open position to remove the anti-theft device from the cassette. In a preferred embodiment of this type of magnetic latch, the latch is provided with a spring-biased slider that can be moved inside the frame along the aforementioned side edge surface. The slider The block is held in the blocked position by a latching tongue attached to the frame and engages a shoulder on the slider.

Description of the invention (1) When the meshing opening tool is set, the slider can be pressed against the junction 1 9 so as to be slightly It is pushed into the frame to resist the bias of the spring, so that the latch tongue made by the force of the magnet green can be easily released under the influence of the magnet. On the other hand, the frictional force between the latch tongue and the shoulder may impair the release of the metal tongue under the influence of the magnet force. This disadvantage is overcome by pushing the slider into the frame in the manner previously described. In another specific embodiment, the slider is not biased by a spring, and in this case, it is not necessary to push the slider into the frame in order to release the latch tongue under the influence of the magnet force open. The aforementioned opening tool facilitates the operation of an anti-theft device with one or another type of magnetic latch. It may also be desirable to disable the opening tool from being used outside business hours and prevent it from being used, and to provide blocks 2 1 and 24 to block the opening tool. A key 32 is used to open the key lock 22 in the block 21, so that the block is lifted from the recess 20 as shown in FIG. 3, so that a cover is located on the recess 15 as shown in FIG. And locked in this position. Similarly, in this way, the key lock 25 in the block 24 can also be opened, and the block can be moved from the recess 23 to the recess 3 3 of the surface 12 and in the recess 3 3 The block 24 is fixed in position by the key lock 25, and the block 24 at this position protrudes from the surface 12 as shown in FIG. The locking and unlocking of the locks of these blocks can be achieved by the transverse pins on the rotatable lock shaft, which can be rotated by the key lock to engage or disengage the groove holes provided on the side walls of the individual recesses. . 10 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm). -------- Order " -------- Elephant (Please read the precautions on the back first) (Fill in this page again) ^ 60654 κι _Β7_ V.
