Claims (1)

[Scope of Claim for Utility Model Registration] In a loading device for a disk-like body that loads a disk-like body inserted into the machine body and positions it at a predetermined position inside the machine body using a positioning mechanism, A pair of guide pieces, which are arranged along a direction intersecting the insertion direction of the disk-like bodies with an interval shorter than the minimum outer diameter of the plurality of types of disk-like bodies to be inserted, each stand at one end in the longitudinal direction. a first guide lever and a second guide lever that are provided and are angularly displaced around the rotation center near the other end in the longitudinal direction; A first through hole is provided at one end in the longitudinal direction to which a pivot piece that stands on the opposite side of the guide piece with respect to the center of rotation of the first guide lever is pivotally fixed, and a second guide lever is provided at the other end in the longitudinal direction. a second passage hole in which a pivot piece standing upright is pivotally fixed between the rotation center of the relay lever and the guide piece, and a relay lever that interlocks the positioning mechanism in accordance with the sliding movement of the relay lever; a movement detection means provided nearby to detect sliding of the relay lever, and the first guide lever and the second guide lever include one of the first guide lever and the second guide lever. Due to the angular displacement movement of the guide lever, the relay lever moves to the second position.
an engaging surface that slides toward the guide lever and engages a pivot piece of the other guide lever in a state where the pair of guide pieces are separated by a predetermined first interval; A loading device for a disk-shaped body, characterized in that the engagement can be released by an angular displacement operation of a guide lever, and the engagement can be expanded to a second interval that is longer than the first interval.
