PURPOSE:To realize the inexpensive imposition system where no coin is required and adopts the off-line system, by providing a stabilizing means giving two stable states to a permanent magnet and a magnet which brings the permanent magnet into a prescribe stable state when a member provided for the imposition deivce is set in the device. CONSTITUTION:When a key holder 1 is inserted to an insertion hole 10 of a controller 8, the magnetized surface of a permanent magnet 9 is arranged to a position opposing to the magnetized surface of a permanent magnet 4, the permanent 4 is turned to a prescribed stable state against a damping member, that is, the permanent magnet 4 is turned to a stable state where different poles of the magnets are opposed to each other (hereinafter referred to as the 1st stable state). The key holder 1 is handed over to the customer at the front desk after the permanent magnet 4 is set to the other stable state (hereinafter referred to as the 2nd stable state) with a magnet at the occasion of checkin. Thus, when the key holder 1 is set to the controller 8, the permanent magnet 4 goes from the 2nd stable state to the 1st stable state. |
