  The penetrating member described above is formed in a shape (for example, a circular shape, an elliptical shape, or the like) that can store a predetermined number of keys (for example, a plurality of about 1 to 10 keys, for example).

<Key holder: First embodiment>
FIG. 1 is a diagram for explaining a first example of a key holder in the present embodiment. A key holder 10 shown in FIG. 1 includes a key ring 11 as a hook-shaped penetrating member for managing in a bundle through a hole provided in a key, and a rod that is moved in a predetermined direction by inserting the key ring 11. 12, a stopper 13 as a holding member that holds the position of the shutter member, an IC tag 14 in which information for identifying at least the key holder 10 is recorded, and communication with the IC tag 14 from outside is cut off. Shutter member 15 and a spring member 16 made of an elastic member having a spring force for moving the shutter member 15 in a predetermined direction.

  1A shows a state before use (before the key is attached), FIG. 1B shows a state when the key is locked (when the key is attached), and FIG. 1C shows a state when the device is broken (when disconnected). Shows the state. 10a shows a cross-sectional view of the key holder 10, and 10b shows an upper cross-sectional view of the key holder 10.

  As shown in FIG. 1A, in the state before use, one end of the key ring 11 is not inserted into the key holder body, and the shutter member 15 has the shaft 18 moved by the spring force of the spring member 16. It is held by the stopper 13 without rotating to the center. The stopper 13 is configured to be broken and removed by applying an external force. For example, the stopper 13 is formed of an inflexible resin that is easily broken by an external force.

  The spring member 16 is an elastic member for moving the shutter member 15 in a predetermined direction around the shaft 17. The shutter member 15 allows the IC tag 14 to transmit and receive data (communication) by an external reading device or the like. It is made of a material that makes it impossible (for example, metal, ceramics, etc.).

  In the configuration described above, first, a predetermined number of keys managed by the key ring 11 are inserted, and the inserted key ring 11 is inserted into the key holder body (rod 12 side). As a result, as shown in FIG. 1 (b), the key ring 11 is inserted into and accommodated in the key holder body, whereby the key is prevented from coming off from the key ring 11, and the rod 12 is pushed in a predetermined direction.
