PROBLEM TO BE SOLVED: To improve the portability, operability, durability, and reliability. SOLUTION: A carrying mechanism 30 for carrying in and out an optical card C to a tray 26 is constituted of a knob 25 provided outside a box body 21, driving gear 31 integrally provided through a driving shaft 32 with the knob 25, an arm 33 provided at the driving shaft 32 so as to be freely rotatable, a slave gear 34 supported by the arm 33 and engaged with the driving gear 31, a carrying roller 34 integrally connected with the slave shaft 35 of the salve gear 34 for carrying the optical card C, a receiving roller 37 for holding the optical card C cooperatively with the carrying roller 36, and an energizing means 38 for energizing the arm 33 to the optical card C side. When the optical card C is butted to a stopper plate 26c of the tray 26 while the optical card C is being carried, in the arm 33 is rotated in B direction, and the pressurizing force of the carrying roller 36 is decreased. When the movement of the optical card C is interrupted while the optical card C is being carried, the arm 33 is rotated to a direction opposite to the B direction, and the pressurizing force of the carrying roller 36 is increased. |
