Claims

[Claims for Utility Model Registration] 1. A unit frame is provided so as to be movable forward and backward with respect to a fixed frame, and an interlocking arm is attached so as to be rotatable about an axis provided on the fixed frame, into which the tip of the operating handle is inserted. A lever interlocking mechanism in which a lock collar is attached to the tip of the interlocking arm so as to be slidable and biased in the extension direction, and the rotational movement of the interlocking arm based on the rotational operation of the operating handle is converted into forward and backward movement of the unit frame. forming an elongated hole in the front surface of the fixed frame, the elongated hole corresponding to the locus of movement of the tip of the lock collar attached to the interlocking arm and having a width smaller than the outer diameter of the lock collar; An automatic position lock for a unit insertion/removal mechanism, characterized in that a notch is formed at a position corresponding to the fixed position of the unit, the diameter of which is larger than the width of the elongated hole and the diameter of the lock collar, and from which the tip of the lock collar protrudes. Device. 2. The operating handle has a flange part smaller in diameter than the notch part and larger in diameter than the width of the elongated hole in the middle part of the tip of the lever, and the diameter of the tip part is smaller than the flange part of the elongated hole. The unit insertion/removal unit according to claim 1 of the utility model registration claim, characterized in that the diameter is larger than the width, and the diameter of the intermediate portion between the collar portion and the grip portion is smaller than the width of the elongated hole. Mechanism automatic position locking device.
