As shown in FIG. 4.6, the top part 3 has each slot 7 and barrier 59 connected to an article 11, i.e. The ring is arranged so as to pass through each open lower portion 5 in each compartment 73 so as to pass through the ring. It will be done. Therefore, the article 11 can be captured and held by the anti-theft device 1.

The upper surface 77 of the tongue piece 59 is sloped as shown in the figure, so that the article cannot be placed in the theft prevention device 1. When it is necessary to insert the article 11 or ring into the slot 7 so as to fix the , as shown on the right side of FIG. to move the holding means 13 laterally to pass the article 11, ie the ring.

When the bottom end 79 of the loop portion of the ring passes through the tongue 59, the retaining means 13 is removed as shown in FIG. is pushed by the biasing force of spring 71 to the position shown on the left side of , i.e. the ring is in the open lower part. successfully enters the elongated shaped compartment 73 and into the tongue 59 on the retaining means 13. Therefore, it is captured and retained. The article 11 is fixed by such a method, and the article 11 is without activating the plate 51 or the motor 33 and already fixed to the base part 1. It is possible to insert the stolen item 11 into the anti-theft device without making it unsafe. can.

Plate 51 extends from the underside of top portion 3 by engaging cutouts on each side edge of compartment 73. arranged so as to slide against the Although this point is not explicitly shown in the figure, it is shown in Figure 3. The compartment 73 also has an extension 81 on each side edge at point p. Excision of plate 51 The section 83 almost corresponds to the position of each compartment 73, and the shape of the cut section 83 corresponds to the position of each compartment 73. is placed on the extension 81 on the compartment 73 and the plate 51 is flush with the top part 3. It is configured to slide forward and/or backward. For this reason, the plate 51 is gripped and held against the top part, but slides within the limits of the top part, It can be seen that the stage 13 releases its hold on the article 11 by means of release means. The means of release is Generally consists of plate 51, motor 33, starting means 21, transmitter 19 and receiver 17 .

The remote control circuit will be explained below. The operation of the transmitter shown in Fig. 7 is as follows. . Actuation of the button 85 on the starting means 21 activates the circuit and the - set of infrared radiation is activated. A diode 78 that emits light pulses 1. Emit R0 light.

Comparator 97 is noise It is used to set the operating threshold to eliminate noise and optical interference. comparison The output terminal of the integrator 97 is connected to an integrator 99. This integrator has fast rise and slow fall have characteristics. This characteristic allows the article 11 to be released immediately upon actuation of the starting means. , and then, with a delay of approximately 2 seconds, the release means is moved to secure the article to the anti-theft device 1. When this occurs, the next release of the starting means 21 takes place. Paraphrase 85 (7) After solution M After a two second delay, the motor 33 drives the plate 51 in the opposite direction to steal the item 11 again. ・([Fixed to the prevention device 1. The desired article is removed from the slot 7 within this period. There must be. Otherwise it will be fixed to the anti-theft device 1 again.
