  The operation of attaching the key to the ring 42 removed from the key holder 40 will be described with reference to FIGS. In the present embodiment, the ring 42 has a substantially rectangular line shape such as a wire, for example, and the end portions of the upper edge portions thereof overlap each other. More specifically, both end portions of the ring 42 are bent into L-shapes, and a U-shaped overlapping portion is formed by combining the L-shaped portions of the two end portions at the upper edge portion of the ring 42. . Here, compared to the case where the ring has a substantially circular linear shape, a plurality of keys are held in the ring 42 by using the substantially rectangular linear ring 42 in the present embodiment. Even in this case, the lower end portion of each key can be prevented from spreading in the horizontal direction. When the key is held by such a substantially rectangular linear ring 42, the operator opens the overlapping end portion of the upper edge portion of the ring 42 as shown in FIG. Insert the key mounting hole into the end. As a result, the key is attached to the ring 42 as shown in FIG. 8D through the state shown in FIG.

  Further, as shown in FIGS. 9A to 9C, the ring 42 attached to the key holder 40 can be rotated about 300 ° with respect to the key holder 40. As a result, the stowability of the key holder 40 can be improved. More specifically, in the conventional key holder, the ring for holding the key can be rotated only about 180 ° with respect to the key holder. In this case, since the ring cannot be brought close to the upper surface or the lower surface of the key holder, there is a problem that the storage performance of the key holder is poor. On the other hand, in the key holder 40 of the present embodiment, the ring 42 can be brought closer to the upper surface and the lower surface of the main body portion 40a of the key holder 40 as shown in FIG. 9A and FIG. It becomes possible to store the key holder 40 in a narrow space, so that the storage performance of the key holder 40 can be improved.

  The ring that is detachably attached to the key holder 40 is not limited to a substantially rectangular line shape as shown in FIG. As a ring that is detachably attached to the key holder 40, a ring as shown in FIGS. 12A and 12B may be used. In the ring 42a shown in FIG. 12 (a), the lower linear portion has a V-shape so as to protrude downward, and in the ring 42b shown in FIG. This is a curved shape (U-shape) in which the linear portion is convex downward. In the case of using the ring 42a shown in FIG. 12A or the ring 42b shown in FIG. You will be able to bring a key to.

  As shown in FIG. 6, a light guide plate 44 is attached to the upper surface of the key holder 40. The light guide plate 44 emits light of each color by receiving light of each color emitted from an LED 32d, which will be described later, provided in the holder housing portion 32.

  As shown in FIG. 7, a detection tag 41 is provided on the back surface of the main body portion 40 a of the key holder 40. Here, the detection tag 41 is attached to the drawer portion 40b, and when the drawer portion 40b is pulled out from the main body portion 40a, the detection tag 41 also moves within the main body portion 40a integrally with the drawer portion 40b. ing. Further, a photo sensor 32 c is provided in the inner part of the accommodation hole 32 a of the holder accommodation part 32. More specifically, the optical axis of the photosensor 32c extends in a direction perpendicular to the paper surface of FIG. 7, and the key holder is in a state where the drawer portion 40b is at the storage position as shown in FIG. When 40 is accommodated in the accommodating hole 32a of the holder accommodating portion 32, the detection tag 41 is detected by the photosensor 32c. As a result, the control unit 50 of the key management machine 10 described later determines that the key holder 40 accommodated in the holder accommodating unit 32 is in a locked state. On the other hand, as shown in FIG. 7B, when the key holder 40 is accommodated in the accommodation hole 32a of the holder accommodation portion 32 with the extraction portion 40b in the extraction position, the detection tag 41 is not detected by the photosensor 32c. . As a result, the control unit 50 of the key management machine 10 to be described later determines that the key holder 40 accommodated in the holder accommodation unit 32 is in a released state.

  As shown in FIG. 7, an IC tag 40 m is attached to the back surface of the main body portion 40 a of the key holder 40. Further, a reader / writer 32b is provided at the back of the accommodation hole 32a of the holder accommodation portion 32, and is stored in the IC tag 40m when the key holder 40 is accommodated in the accommodation hole 32a of the holder accommodation portion 32. Information is read by the reader / writer 32b, and various information is written to the IC tag 40m by the reader / writer 32b. Here, for example, the identification number of the key holder 40 is stored in the IC tag 40m. Specifically, as described above, the key holders 40 accommodated in the upper holder accommodating portions 32 of the three rows of holder accommodating portions 32 are assigned identification numbers 1 to 10 in order from the left. The key holders 40 housed in the middle holder housing parts 32 are assigned identification numbers 11 to 20 in order from the left, and the key holders 40 housed in the lower holder housing parts 32 have Identification numbers 21 to 30 are assigned in order from the left. The IC tag 40m provided on the key holder 40 stores such an identification number of the key holder 40 (specifically, any one of 1 to 30).

  Further, in the present embodiment, when the key holder 40 is accommodated in the accommodation hole 32a of the holder accommodation portion 32, information stored in the IC tag 40m is read by the reader / writer 32b, or the IC tag is read by the reader / writer 32b. Based on various information written in 40 m, the control unit 50 of the key management machine 10 described later determines that the key holder 40 is stored in the holder storage unit 32. Instead of such a mode, when the key holder 40 is accommodated in the accommodating hole 32a of the holder accommodating portion 32, the IC tag 40m is detected by the reader / writer 32b, so that the key holder 40 is placed in the holder accommodating portion 32.
