。[Claims for Utility Model Registration] (1) In a floppy disk device using a recording medium housed in a plastic case, a cleaning liner provided on each inner surface of the plastic case corresponding to both sides of the recording medium; A bone-like structure formed on one side of each inner surface of the plastic case, and having a plurality of linear protrusions whose longitudinal direction is the rotational direction of the recording medium at predetermined intervals in the radial direction of the recording medium. 1. A medium case for a floppy disk device, comprising: a rib configured such that an outflow side of the linear protrusion with respect to the rotational direction of the recording medium is guided toward an outer peripheral side of the recording medium. (2) In a chucking mechanism of a floppy disk device in which a chucking plate provided at the center of a recording medium is attracted by the magnetic force of a magnet to chuck the recording medium to a rotating mechanism, when chucked by the rotating mechanism; A positioning device that moves within a predetermined range so as to rise so as to fit into a positioning hole provided in the tracking plate of the recording medium and to descend while being pressed by the tracking plate. The pin constitutes a movable mechanism for this positioning pin,
A chucking mechanism for a floppy disk device, comprising: a positioning pin moving mechanism having an elastic member for moving the positioning pin within the predetermined range from a fixed reference position.
