  • the lock lever 127 is pivoted downward about the pin 127a to engage the hook 127b with the lock piece 115, thereby closing the lock holes 115a and 127c with a lock closing tool 118.
  • the lid 120 is locked to the safe main body 110.
  • a shielding plate 129 and a lock lever 132 are disposed at both corners on the safe insertion side in the lid 120, as shown in Fig. 2.
  • the shielding plate 129 is supported to swing about a pin 130 and is biased counterclockwise by a leaf spring 131.
  • a rectangular coin storage open window 129a is inclined at the central portion of the lid 120, and a groove 129b corresponding to the insertion port 125a is formed at the center of the lid 120 on the safe insertion side.
  • An engaging pawl 129c and an engaging portion 129d constitute a notched portion so as to surround the lock lever 132 located at the other corner.
  • a lock pawl 132b engaged with the engaging pawl 129c and an engaging protrusion 132c engaged with the actuating piece 111b are formed in the lock lever 132.
  • the lock lever 132 is supported to swing about a pin 132a extending on a cover 133 of the lock lever 132.
  • a pin 132d integrally formed with the lock lever 132 is fitted in a sector-shaped elongated hole 133a formed in the cover 133 and is slid along the elongated hole 133a. Therefore, the lock lever 132 swings within the range of the elongated hole 133a.
  • a coin spring 134 is hooked between the pin 132d of the lock lever 132 and a pin 134a extending on the cover 133. This coin spring 134 serves as a tumbler mechanism acting on the lock lever 132.
  • the movable fulcrum (pin) 132d is biased to the upper end side of the elongated hole 133a, thereby applying a counterclockwise biasing force to the lock lever 132 so as to pivot it about the pin 132a.
  • the movable fulcrum 132d is located below the boundary line K, the movable fulcrum 132d is biased toward the lower end side of the elongated hole 133a, thereby applying the clockwise biasing force to the lock lever 132 so as to pivot about the pin 132a.
  • the lock lever 132 is swingable with respect to the boundary line K.
  • An opening (insertion port) 141a for loading the coin box 101 is formed in the front surface portion of a safe chamber 141, as shown in Fig. 3.
  • a drop window 142 for storing a coin, dropping from a coin handling unit (not shown) disposed above the safe chamber 141, in the coin box 101 is formed in correspondence with the storage chamber 121a of the coin box 101.
  • An actuating rod 143 having a pin 143a at the distal end thereof extends on the rear portion in correspondence with the insertion port 125a of the lid 120.
  • the coin box of the present invention has the above structure and is operated as follows.
  • the movable fulcrum 132d of the lock lever 132 is located below the boundary line K in advance by a preset operation (to be described later).
  • the lock pawl 132b is kept disengaged from the engaging pawl 129c, and locking of the shielding plate 129 by the lock lever 132 is released.
  • the pin 143a of the actuating rod 143 extending from the rear portion of the safe chamber 141 extends from the insertion port 125a of the coin box 101 into the lid 120, as shown in Fig. 4A.
  • the pin 143a abuts against the stepped portion of the groove 129b of the shielding plate 129, so that the shielding plate 129 is pivoted clockwise about the pin 130 against the biasing force of the leaf spring 131.
  • the engaging portion 129d of the shielding plate 129 is engaged with the movable fulcrum 132d of the lock lever 132, and the lock lever 132 tends to be pivoted counterclockwise about the pin 132a.
  • the coin storage open window 129a of the shielding plate 129 is located at the storage window 121a of the lid 120, as shown in Fig. 4B.
  • the storage window 121a is located at the drop window 142 of the safe chamber 141, so that the coin from the coin handling unit (not shown) can be stored in the coin box 101.
  • the movable fulcrum 132d of the lock lever 132 is located at the upper end portion of the elongated hole 133a through the boundary line K, so that the lock pawl 132b and the engaging protrusion 132c are located at the standby positions to be engaged with the engaging pawl 129c of the shielding plate 129 and the actuating piece 111b of the safe main body 110.
  • the pin 143a of the actuating rod 143 is brought into direct contact with the groove 129b of the shielding plate 129 to pivot the shielding plate 129. Therefore, a complicated structure need not be used, and the number of constituent members can be greatly reduced.
  • the lock lever 127 and the lock piece 115 of the coin box 101 unloaded from the safe chamber 141 are released, the lid 120 is slid backward along the guide rails 111a and 112a, and the opening 113 of the safe main body 110 is open to recover the coins.
  • the lock member 132 is set swingable about the pin 132a thereof and is swung during slidable movement of the lid for coin recovery, thereby disengaging the engaging pawl 129c of the shielding plate 129 from the lock pawl 132b of the lock member 132 to obtain the preset state. Therefore, the pivot movement of the lock member is performed on the same plane on which an external force acts on the lock member 132. Therefore, an unnecessary external force does not act on the lock member 132, and damage to the lock member 132 and its failure can be minimized.
  • the lock member has the engaging protrusion and the lock pawl engaged with the engaging pawl of the shielding plate to hold the storage window shielding state of the shielding plate, and the swinging position of the lock member is reversed by the tumbler mechanism.
  • the actuating portion formed in the safe main body is engaged with the engaging protrusion of the lid to swingably reverse the lock member, so that the lock pawl is disengaged from the engaging protrusion of the shielding plate to obtain the preset state. An unnecessary force does not act on the lock member to obtain the preset state, thereby minimizing the failure.
  • the shielding plate Since the shielding plate is swung by the actuating rod formed in the safe chamber against the swinging force to open the storage window in loading the safe main body in the safe chamber, the actuating rod is brought into direct contact with the shielding plate. For this reason, a complicated structure need not be used, and the number of constituent members can be greatly reduced.
  • the lid which can freely open the opening of the safe main body is slidable with respect to the opening of the safe main body, the lid is rigidly mounted on the safe main body. For this reason, the lid tends not to be damaged. Coins will not be stolen even if the coin box is illegally taken away.
