Claims (1)

[Claims for Utility Model Registration] A disk that removably accommodates a disk cartridge 2 containing a disk-shaped information storage medium 4, and records and reproduces information by rotationally driving the stored information storage medium 4. The drive device includes a main body 14 having a pair of side plates 90 facing each other and at least two guide parts 55 formed on each side plate 90, and an engaging part that engages with each guide part 55 of the main body 14. 54 and is slidably supported along the guide portions 55; and a disk holder 52 that is slidably supported by the main body 14 and comes into sliding contact with the engaging portions 54 that are engaged with the respective guide portions 55. Cam part 50
a slide member 22 that slides the disk holder 52 along the guide portion 55 by a cam action; an elastic member 25 that biases the slide member 22 in a desired direction; When the disk cartridge 2 is ejected, the slide member 22 moves against the elastic force of the elastic member 25 to maintain its moving state, and when the disk cartridge 2 is inserted. A locking means 28 that sometimes releases the engagement with the slide member 22 and moves the slide member 22 in a desired direction by the elastic force of the elastic member 25; and a position for detecting the insertion position of the disk cartridge 2. a detection means 86; a plate 62 supported by the disk holder 52 so as to be slidable in the insertion/ejection direction of the disk cartridge 2; and a plate 62 rotatably supported by the plate 62 and engaged with the inserted disk cartridge 2. A disk clock means 74 having a locking portion 76 that can be fitted together; a rotating body 40 that is rotatably provided on the main body 14 and having a locking portion 42 that protrudes in one direction; and a rotating body 40 that can be rotated in both forward and reverse directions. a drive means 34 for rotational driving; rotatably supported by the slide member 22;
a slide member driving means 44 having a long hole 46 that slidably engages with the locking portion 42 of the rotary body 40; one end rotatably engaged with the locking portion 42 of the rotary body 40; a plate driving means 70 whose end is supported by the plate 62, and operates the driving means 34 in one direction based on the detection of insertion of the disk cartridge 2 by the position detecting means 86, and drives the disk from the outside. By operating the driving means 34 in the opposite direction based on a command to eject the cartridge 2, the rotating body 40, the slide member driving means 44, and the plate driving means 70 are operated to insert and eject the disk cartridge 2. A disk drive device characterized by:
