Is attached to the front of the front frame.

[0003] There are two types of locking means, a locking means used for a so-called normal machine and a locking means used for a CR machine, both of which have different locking principles and differ greatly in accuracy. . That is, the locking means for a normal machine is such that an engaging shaft is rotatably provided inside a cylindrical lock body via a bearing, and a cylindrical key is inserted into the keyhole side of the lock body. The lock piece is operated in the release direction via the engagement shaft by the key.

On the other hand, in a locking means for a CR machine, for example, as described in JP-A-3-234275, an inner cylinder and an outer cylinder are provided inside a lock body so as to be rotatable relative to each other.
It can be used by performing a predetermined operation, such as inserting a protruding pin, spacer, etc. across both cylinders, alternately inserting a plurality of types of plate-like keys into the key insertion hole and turning in a predetermined direction. A variable type that can change the type of the plate key is used. The lock body of each locking means is integrally provided with a mounting portion on the rear end side, and in a state where the lock body is fitted into the lock hole of the front frame from the back side, the mounting portion is fixed to the back surface of the front frame with screws. ing. The lock cover is manufactured separately for the normal machine and for the CR machine, and is attached to the front frame such that the key insertion opening corresponds to the front side of the lock body.
