<p>The object is to prevent the erroneous insertion of a disk cartridge in a direction 90 degrees different from the correct direction while suppressing an increase in the number of components and to smoothly and securely transfer the disk cartridge. There is provided a lock lever capable of locking the cartridge while being pivotally supported by a slider that transfers the cartridge between a mounting and dismounting position and an insertion completed position with respect to a holder. The lock lever pivots while being engaged with the disk cartridge that is being inserted, and a first pivot amount when the cartridge is being inserted with a wide width of insertion in the correct direction is set smaller than a second pivot amount when the disk cartridge is being inserted with a narrow width of insertion in the incorrect direction. The holder is provided with a stop rib that allows the movement of the lock lever in the direction in which the cartridge is inserted in the case of the first pivot amount and prevents the movement in the case of the second pivot amount. <IMAGE></p> |
