  The structure of the wiring support 70 spanned from the back plate 17 of the fixture main body 1a to the rear side of the drawer 202 is such that the upper flange member 71 and the lower flange member 72 on one end side of the metal rod-like upper flange member 71 and the lower rod member 72 With both portions 72a being spaced apart by a predetermined distance in the vertical position, both pivoted portions 71a and 72a are pivotally supported by the shaft 73, so that both the upper collar material 71 and the lower collar material 72 are bent around the shaft 73. Bendable or extendable. A shaft 74 is welded and fixed to the lower end of the other end portion 71b and the end portion 72b of the upper brim member 71 and the lower brace member 72 so as to face downward.

  A support fitting 77 bent with a metal plate is attached in the vicinity of the rear corner of the storage portion 103a. A metal fitting 76 is attached. A bearing hole (not shown) penetrating vertically is formed in the support fitting 77 and the support fitting 76, and the shaft 74 of the end 72b of the lower collar member 72 is loosely inserted into the bearing hole of the support fitting 77 to support it. The wiring support 70 can be easily attached by loosely inserting the shaft 74 of the end 71 b of the upper collar 71 into the bearing hole of the metal fitting 76.

  In addition, by providing the lower collar 72, which is one side of the wiring support 70, at the rear corner of the drawer 202, the rear corner, which is a blind spot space, can be used effectively, and the drawer 202 and the fixture main body 1a can be used. Therefore, both ends 71b and 71a of the wiring support 70 can be supported in a stable state by the support fittings 77 and 76.

  A holder 71c is provided in the vicinity of the end 71b and the pivot part 71a of the upper collar 71, and the same type of holder 72c is also provided at the end 72b and the pivot part 72a of the lower collar 72. The communication cable 2 wired along the upper surface of the upper collar 71 from the back plate 17 side is fixed by the holder 71c, and the communication cable 2 wired along the lower surface of the lower collar 72 is further retained by the holder 72c. The communication cable 2 can be supported without dropping from the wiring support 70 when the drawer 202 described later is stored and pulled out.

  The communication cable 2 is inserted into a wiring groove 62 formed in the upper rear end of the partition plate 60 along the rear inner surface of the drawer 202 and drawn into the space 50. In this manner, the communication cable 2 can be easily drawn into the space 50 by inserting the communication cable 2 through the wiring groove 62 formed in the upper part of the rear end of the partition plate 60.

Therefore, the communication cable 2 extending from the wiring support 70 side can be easily connected to or removed from the communication cable on the RFID antenna 46 side via the connector 80.

  Similarly, the left storage unit instruction lamp 212 a and the right storage unit instruction lamp 212 b provided on the front plate of the drawer 202 are also connected to the communication cable 2 extending from the wiring support 70 via the wiring groove 62 behind the partition plate 60. Then, it is drawn into the space 50 and then connected through the wiring grooves 62 and 62 in front of the partition plate 60 via a connector (not shown).

  Therefore, by routing the communication cable 2 in the space portion 50 formed between the partition plates 60 and 60 facing the front-rear direction of the center portion of the drawer 202, the communication cable 2 is left and right inside the space portion 50. Since it can be connected to the RFID antenna 46, which is a reading device for the RFID partition plates 44a and 44b facing in the direction, the communication cable 2 hinders articles stored in the left storage portion 103a and the right storage portion 103b of the drawer 202. There is nothing.

  A lid 75 can be attached to the upper end of the space 50, and the lid 75 is fitted between the partition plates 60 and 60 and between the front and rear of the drawer 202 while moving the longitudinal direction of the lid 75 forward and backward. The position is fixed by inserting. Thus, when the space part 50 is closed with the lid 75, the communication cable 2 wired in the space part 50 can be shielded from the outside and protected from the outside, and the storage part is accommodated by the lid 75. Articles and the like stored in 103a and 103b are prevented from falling into the space 50 in advance.

  The predetermined arrangement position of the RFID antenna 46 on the position-movable RFID partition plates 44a and 44b is as shown in FIG. 2 in the right storage portion 103b of the drawer 202 made of an electromagnetic shielding material. It is a position that is spaced from the front front plate by a predetermined distance (L1), spaced from the rear rear plate by a predetermined distance (L2), and spaced from the bottom plate by a predetermined distance (L3).

  As for the distance between the RFID antenna and the electromagnetic shielding material, the electromagnetic wave from the RFID antenna is received by the RFID tag without being affected by the electromagnetic shielding material, and the electromagnetic wave from the RFID tag is not affected by the electromagnetic shielding material. It has been experimentally verified that at least the distance between the RFID antenna and the electromagnetic shielding material is preferably 40 mm or more so that the RFID antenna can receive the signal.

  Therefore, in this embodiment, the distance (L1) between the RFID antenna 46 disposed on the RFID partition plates 44a and 44b and the front plate of the right storage portion 103b is 50 mm, and the back of the RFID antenna 46 and the right storage portion 103b is used. The distance (L2) from the face plate was set to 50 mm, and the distance (L3) between the RFID antenna 46 and the bottom plate of the storage portion 103b was set to 50 mm.

  As shown in FIG. 4, the inside of the drawer 202 is partitioned into a left storage portion 103a and a right storage portion 103b by RFID partition plates 60, 60, and a file case 14 is placed in the left storage portion 103a and the right storage portion 103b. A plurality of files are stored, and RFID tags 30 are attached to both side surfaces of the file case 14.

  Even when the RFID partition plate 44a and the RFID partition plate 44b are attached to any of the locking grooves 61 and 61 ', the RFID antenna 46 is always separated from the side plate of the drawer 202 and the partition plate 60 by a predetermined distance or more. Specifically, an indirect member 48, which is a non-electromagnetic shielding material, is provided at the left and right ends of the RFID antenna 46 in the RFID partition plates 44a and 44b, thereby making the RFID antenna 46 electromagnetic. The partition plates 60 and 60 that are shielding materials and the side plates of the drawer 202 are spaced apart by a predetermined distance.

  Therefore, in this embodiment, the distance (L4) between the RFID antenna 46 disposed on the RFID partition plates 44a and 44b and the both side plates of the drawer 202 is set to 50 mm, and the distance between the RFID antenna 46 and the partition plates 60 and 60 is set. (L5) was 50 mm.

  Therefore, even if the RFID partition plates 44a and 45b are attached to any of the attachment positions of the formed locking grooves 61 and 61 ', the RFID antenna 46 is a drawer 202 made of an electromagnetic shielding material. The RFID tag 30 attached to the file case 14 stored in the left storage portion 103a and the right storage portion 103b without being affected by the front plate, the rear plate, the bottom plate, the side plate, and the partition plates 60, 60. It is configured to transmit and receive electromagnetic waves.

  Note that the RFID tag 30 attached to the file case 14 is attached to each of the file cases 14 stored in the left storage portion 103a and the right storage portion 103b while being shifted in position. When reading the article information of the RFID tag 30 at the same time, it is possible to prevent the occurrence of a reading error, and the article information is accurately read out.

  Next, the movable state of the wiring support 70 during the movement of the drawer 202 will be described. First, when the drawer 202 is pulled forward from the fixture main body 1a using the handle 220, the shaft 74 of the upper rod material 71 and the shaft 74 of the lower rod material 72 are pivotally supported by the support fittings 76 and 77, respectively. Further, the upper collar member 71 and the lower collar member 72 are rotated around the shaft 73 located at the pivotally attached portions 71a and 72a at the center of the wiring support 70, and both the flange members are gradually extended. Further, when the drawer 202 is pulled forward, the upper collar member 71 and the lower collar member 72 are stretched so as to be substantially one collar member. Similarly, the communication cable 2 on the wiring support 70 is also extended along the upper collar material 71 and the lower collar material 72.

  Next, when the drawer 202 is housed toward the drawer storage box 202a from the state in which the drawer 202 is pulled out, the upper collar material 71 and the lower collar material 72 rotate around the shaft 73, and the two The saddle members 71 and 72 are brought close to each other, folded in half, bent in a reverse “<” shape when viewed from above, and stored compactly.

  Then, as shown in FIG. 5, when the drawer 202 is completely housed in the fixture body 1a, the upper support member 71 and the lower support member 72 of the wiring support 70 are bent so that they overlap each other, Since it is stored compactly along the face plate 17, space can be saved without occupying the space of the drawer storage 200 a in the fixture body 1 a as much as possible, and between the upper and lower parts of the upper casing material 71 and the lower casing material 72. Since a predetermined interval is formed, the communication cable 2 is not sandwiched between the upper and lower saddle members 71 and 72.

  Furthermore, since the movement of the upper collar member 71 and the lower collar material 72 during bending and extension is always constant, an excessive external pressure is not easily applied to the communication cable 2 wired on the upper collar material 71 and the lower collar material 72. In addition, since the communication cable 2 is prevented from being deteriorated and caught, the communication cable 2 is prevented from being damaged in advance, and the durability is improved and long-term use is possible.

  According to the above description, in the first embodiment, the communication cable 2 is drawn into the space 50 from the back plate 17 side of the fixture body 1a through the wiring support plate 70 along the rear plate at the rear portion of the drawer 202. Since the communication cable 2 does not enter the storage unit 103a, it does not interfere with items such as the file case 14 stored in the left storage unit 103a.

  In addition, since the communication cable 2 and the RFID antenna 46 serving as a reading device are connected via the connector 80 in the space 50, the communication cable 2 can be easily connected to and removed from the RFID antenna 46. Furthermore, since the communication cable in the space 50 is protected from the outside by the partition plates 60, 60, the communication cable 2 can be prevented from being deteriorated or damaged.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a plan sectional view showing the drawer when it is housed in a fixture.
