ある。According to the conventional device, it is not necessary to replace the card reading device itself or some parts even after the construction period, and the construction card can be used only during the construction period. The illegal use of the card can be avoided, and the mechanical setting of the device can be switched from the use of the construction card to the use of the normal card (owner card) by the first use of the normal card.

ましくない。[0006] However, this device still has drawbacks to be improved. That is, it is easily estimated that the resting magnetic pin, which is inactivated by the magnetic pin holding member during the construction period, is arranged at a position corresponding to the cutout portion of the construction card at the time of insertion. Normally, the magnetizing part of the card has the same arrangement and polarity as the magnetizing part of the construction card except for the magnetizing part corresponding to the rest magnetic pin. Unauthorized copying of a normal card may be extremely easy, which is not preferable for crime prevention.

The magnetic pin 4a, which is fitted over the second facing member 12a and restrains the positionable second facing member 12 at the front position (the left position in FIGS. 1 and 2) with respect to the first facing member 2. However, since it is pushed into the first pin hole 2a by a part of the magnetized portion 16b that can be displaced by magnetic force and coincides with the shear line, the contact means 22 in the state of protruding into the card insertion passage 1d is The card is pushed by the tip of the card 16, and the second opposing member 12 is moved as shown in FIG.
Further, as shown in FIG. 4, the front position is reached, and the contact means 22 is retracted from the card insertion passage 1d due to gravity and / or the bias of the spring at that position.
