Abstract

PURPOSE:To improve maneuverability by using the 1st spring as a lifting means for a disk cartridge and the 2nd spring as a lowering means for the disk cartridge and electrically unlocking a slider. CONSTITUTION:Under a locked status, the slider 13 is energized in an arrow 22 direction by the force of the 1st spring 14 and a horizontal guiding member 3 is also energized in an arrow 23 direction by the slider 13. When recording/ reproducing operation is electrically completed at the time of ejection, the rotation of a disk is stopped and an electromagnetic plunger 21 is actuated, so that the 1st lock lever 17 is rotated in an arrow 29 direction. Consequently, the 1st lock lever 17 is unlocked from the 1st pin 16 and the slider 13 is moved in an arrow 22 direction by the force of the 1st spring 14. Since the slider 13 is engaged with a horizontal guiding member 3 at a part 13a where the slider 13 is abutted upon the member 3, the member 3 is also moved in the arrow 22 direction.
