  • step S5 the control means 24 determines whether or not an authentication signal has been received based on the input from the wireless communication unit.
  • step S5 If it is determined in step S5 that the authentication signal has not been received, the control means 24 returns to step S4 and repeats the processing loop of steps S4 and S5 until it is determined in step S4 that the elapsed time since the activation switch 24a was operated has reached the set time, or until it is determined in step S5 that the authentication signal has been received.
  • step S4 determines in step S4 that the elapsed time from the time the start switch 24a was operated has reached the set time while repeatedly executing the processing loop of steps S4 and S5, the control means 24 proceeds to step S1 and restarts the power saving mode.

  • the rotational force of the servo motor 23a is transmitted via the pinion gear 23b to the rack 23c formed on the latch operation piece 22 that meshes with the pinion gear 23b, causing the latch operation piece 22 to slide (advance).
  • the slidable (advance) latch operation piece 22 retracts the latch 21 that is biased in the protruding direction by the spring 21a and is engaged with the housing body 11, thereby releasing the latch 21 from the housing body 11, and the lid 12 is opened by the biasing force of the ejector pin 14 biased by a spring provided on the housing body 11.
  • control means 24 rotates the servo motor 23a in the opposite direction to the previous direction, so that the latch operation piece 22 slides (retracts).
  • the time from when the latch operation piece 22 is slid (forward) until it is slid (backward) can be set to about one to several seconds.
  • the lid 12 is locked in an open position at approximately 90 degrees by the hinge, and in this position the key stored in the key storage space 12a can be removed.
  • step S6 When the user has finished using the key, he or she returns the key into the key storage space 12a and then rotates the lid 12 to close it. Because the latch operating piece 22 has been slid (retracted) in step S6, simply closing the lid 12 causes the latch 21 on the lid 12 to engage with the housing body 11, keeping the lid 12 in the closed position and locking it, preventing the key from being removed.
  • the control means 24 returns to the initial state (step S7), returns to step S1, and restarts the process from step S1.
  • control means 24 can be equipped, as necessary, with a detection means for detecting the open/closed state of the lid body 12, a detection means for detecting the presence or absence of a key in the key storage space 12a, and further with a detection means for detecting the shape (volume) and weight of a key stored in the key storage space 12a so that a malicious user can discover by checking the history that he or she has temporarily replaced a key with a different key in order to duplicate it. This allows the key storage device to be managed more accurately, thereby improving security.
  • a key can be lent only to users who have been authenticated by operating a mobile terminal used as authentication means to emit an authentication signal, and a highly secure key storage device can be provided that can reliably lock the key without causing malfunction of the locking mechanism 2.
  • the control means 24 performs processing to give an opening operation command to the servo motor 23a of the electric operating mechanism 23. Therefore, the control means 24 does not require information such as the user or when the user will use the key. Therefore, there is no need to connect to the outside via a network, and the equipment costs required for automatic key lending can be reduced.
  • the period or time when the key can be used, such as when the authentication signal can be transmitted, can be managed by an application program on the mobile terminal used by the user as authentication means.
  • control means 24 is in a standby state until an authentication signal is input to the wireless communication unit, which reduces the power consumption of the control means 24 including the wireless communication unit.
  • the power source for the control means 24 including the servo motor 23a of the electric operating mechanism 23 and the wireless communication unit can be a primary battery or a secondary battery attached to a battery case 25a arranged in the housing body 11 of the housing 1, and a 9V square dry battery connected to a battery snap 25b for a 9V square dry battery arranged exposed on the housing body 11.
  • the primary or secondary battery attached to the battery case 25a is used as a normal power source
  • the 9V square dry battery connected to the battery snap 25b for the 9V square dry battery is used as an emergency power source in case the normal power source is cut off.
  • the 9V square dry battery used as an emergency power source can be fixed to the housing body 11 by connecting it to the battery snap 25b for the 9V square dry battery, which has the advantage that it does not need to be held by hand.

This makes it possible to prevent the keys (including the card key C) stored in the key storage space 12a from falling out of the gap between the housing body 11 and the lid 12 when the lid 12 is opened or closed.
  • the cover 12 may be provided with a protrusion 12b having a mountain-shaped protrusion on which the card key C rides when the cover 12 is open (when the cover 12 is opened at an angle of approximately 90 degrees).
  • the housing body 11 is provided with a shackle 3 whose protruding dimension from the housing body 11 is adjustable, and a rack 31 is formed on the surface of the shackle 3 to engage with a rack-shaped claw piece 32c of a fixing mechanism 32 for fixing the shackle 3.

  • the fixing mechanism 32 for fixing the shackle 3 comprises an operating piece 32a which can be operated when the cover 12 is open, a claw piece 32c which moves in the front-to-back direction due to an inclined surface 32b formed on the operating piece 32a when the operating piece 32a is operated in the vertical direction, and a spring 32d which biases the claw piece 32c toward the inclined surface 32b.
  • the operating piece 32a fits into a recess 12c of the cover 12 so as not to move downward even if an impact or the like is applied. This prevents the shackle 3 from being released from its fixed state when the cover 12 is closed.

  • the deceleration means 16 is composed of a spring piece 16a formed integrally with the side surface of the lid body 12, and the speed at which the lid body 12 is opened is decelerated by the resistance generated when a protrusion 16b formed on the spring piece 16a moves from a guide groove 16c formed on the side surface of the housing body 11 while abutting against the side surface of the housing body 11. This reduces the speed at which the lid 12 is opened, and prevents the keys (including the card key C) stored in the key storage space 12a from flying out due to impact when the lid 12 is opened.

  • FIG. 15 shows a modified embodiment of the key storage device.
  • This key storage device is an improved version of the key storage device, in which a recess 11c is formed by recessing the periphery of a pressing portion 11a provided on the housing body 11 of the key storage device, and a sticker can be affixed to this recess 11c.
  • a sticker with a picture of fingertips printed on it can be used as this sticker, thereby making it possible to clearly indicate the operation location.
  • this key storage device has a covering edge 12d extended from the upper end of the lid body 12 to cover the upper edge of the opening of the housing main body 11, and a protrusion portion 11d is formed on the housing main body 11 along the covering edge 12d. This eliminates a gap between the upper edge of the opening of the housing body 11 and the upper end of the lid 12, making it possible to prevent the lid 12 from being opened illegally using a screwdriver or the like.
  • this key storage device has a recess 12e formed at the upper end of the lid 12, and a sticker can be affixed to this recess 12e.
  • This sticker may be, for example, a sticker on which a number for identifying the key storage device is printed.
  • the key storage device of the present invention can reliably lock without the locking mechanism malfunctioning, so it can be widely used as a key storage device for storing keys to lock and unlock doors in vacant rental properties, private lodging properties, large company document rooms, and other rooms where access restrictions are required.
