Each magnetization point 55a
Is written to.

The applicant of the present invention has disclosed Japanese Patent Application Laid-Open No. Sho 60-12937.
No. 9 discloses one structural example of the lock 53. The schematic structure will be described with reference to FIG.
First, the casing of the lock 53 is composed of a base plate 56 and a lid 57. The base plate 56 always covers the bank lock 51 and the customer lock 5
2 is fixed to the safe deposit door 54 so as to be exposed, and a hollow rectangular lid 57 is fitted to the base plate 56 so as to be slidable in the longitudinal and lateral directions. An insertion hole 56 a for inserting the authentication card 55 is formed on one side surface of the base plate 56. Inside the lock 53, a safety deposit door 54 is attached to the base plate 56.
Guide plates 58 and 59 for holding the inserted authentication card 55 are fixed in parallel with
A plurality of magnet pins 60 are loosely fitted. The magnet pins 60 are selectively magnetized by a combination of NS polarities as data unique to the safe deposit box contracted by the customer. When the authentication card 55 is not inserted, the magnet pin 60 is moved by a spring (not shown).
Is engaged with the concave portion 61a. Reference numeral 62
Is an engagement lever that rotates around a fulcrum 62a in conjunction with the movement of the moving member 61. When the authentication card 55 is not inserted, the engagement lever engages with the convex portion 63 fixed to the lid 57. Then, the lid 57 is prevented from sliding.

When the valid authentication card 55 is inserted into the lock 53, the magnet pin 60 is pulled out of the concave portion 61a by the magnetic force of each magnetized point 55a of the authentication card 55, and the movable member 61 becomes movable. . When the authentication card 55 is further pushed in, the moving member 61
The contact portion 61b is moved by being pushed by the tip of the authentication card 55. Then, the engagement lever 62 rotates about the fulcrum 62a, and the engagement with the projection 63 is released (the state of FIG. 9B).

That is, an unlocking mechanism that operates in accordance with the data of the authentication card 55 is attached to a base plate 56 fixed to the safe deposit door 54.
Since the structure is provided on the side, as shown in FIG.
At least the customer lock 52
Exposed portion dimension L1 and unlock mechanism installation dimension L
There is a problem in that a casing that covers the area of 2 is required, resulting in a horizontally long opening / closing lock. In addition, since the lid 57 is of a slide type, considering the slide size L3 (because it is inconvenient to project to the front of the adjacent safety deposit box), the width is (L1 + L2 + L3). , And there was a limit in its structure to attach it to the small safe-deposit door. If the pitch of the magnetized points of the authentication card 55 is reduced, the adjacent magnetized points will be influenced by the magnetic force of each other. Therefore, there is a limit to the miniaturization of the authentication card, and the viewpoint of easy handling of the card. Accordingly, it is not advisable to reduce the size of the opening / closing lock by reducing the size of the authentication card, and there has been a demand for an opening / closing lock which can be used as a conventional security card as it is and can be used in a safety box with a small width.

The present invention has been made in order to solve such problems, and provides an opening / closing lock which can use a conventional authentication card as it is and can be attached to a safety box with a small width. It is intended to be.
