In this case, each tumbler 17 is rotated by rotating the tumbler shaft 18 left and right by a predetermined angle, for example, so that all the unlocking grooves 17a are aligned. Specifically, by engaging an engaging claw (not shown) of the tumbler 17 with the adjacent tumbler 17, the adjacent tumblers 17 are sequentially rotated, and all the unlocking grooves 17a are made to coincide. One end of the cannula 16 is inserted into the corresponding unlocking groove 17a, and the other end side of the cannula 16 is removed from the engaged portion 9a to be unlocked.

  In the present embodiment, a case where three tumblers 17 are provided is shown. Since the tumbler shaft 18 is rotated by pulse control on the booth device side unlocking unit 31 side, a scale like a dial code lock is not particularly formed. Assuming that 30 pulses are equivalent to one rotation of the tumbler shaft 18, a total of 27000 lock knitting is performed by the three tumblers 17.

  The tumbler shaft 18 is pivotally supported by the unit frame 14 with the longitudinal direction of the protective box 5 as the axial direction, and the shaft end surface facing the outer surface side of the unit frame 14 is connected to the booth device side unlocking unit 31.
