Claims

[Scope of utility model registration request]

a frame, a cartridge holder that holds a disk cartridge containing a flexible disk; and a guide portion that engages with the cartridge holder, is slidable with respect to the frame, and guides the upward and downward movements of the cartridge holder. a carriage carrying the provided guide member, a first head, and a second head facing the first head and the flexible disk, one end of which is fixed to the carriage for rotational movement. a rotary damper having an arm having a first cantilever protrusion and a second cantilever protrusion at an end, a damper gear fixed to the cartridge holder; The damper gear is movably supported, has a gear meshing with the damper gear at one end, and a first sloped portion at the other end, the first sloped portion engaging the first cantilever projection. , a first rotary lever having an engagement protrusion removably engaged with one end of the guide member at the other end; has a second inclined portion, the second inclined portion engages with the second cantilever protrusion, and a second rotating lever that is rotatable in conjunction with the first rotating lever; In a flexible disk drive device comprising a moving lever and a spring that biases the first rotating lever or the second rotating lever in a certain direction, the disk cartridge is disposed within the flexible disk drive device. a detection circuit that detects that the flexible disk has been inserted into the flexible disk; a control circuit that outputs the detected signal from the flexible disk drive device to the computer; and a control circuit that provides a rotation signal or a stop signal to the drive motor that rotates the flexible disk. a motor control circuit;
A flexible disk drive device comprising: a counter circuit that counts the number of times the drive motor has rotated.
