摘要： The present invention provides lock release means that allows spring constant of the lock release means to be set to any desired value without regard to a material used for a cartridge holder. A disk recording and/or reproducing apparatus includes: recording and/or reproducing means disposed in a chassis; a cartridge holder supported on the chassis movably between an insertion and withdrawal position, at which a disk cartridge is inserted or removed, and a recording and reproducing position, at which the disk cartridge is recorded or reproduced by the recording and/or reproducing means; an eject lever disposed on an upper surface of the chassis so as to be movable in a disk cartridge insertion and withdrawal direction; eject lever lock means disposed on the upper surface of the chassis; and lock release means mounted on the cartridge holder such that a leading end side of the lock release means advances into the cartridge holder from an upper surface of the cartridge holder.

摘要： A disk recording/reproducing apparatus 101 includes: a chassis 103 rotatably supporting a holder 102 for storing a disk cartridge; an eject lever 105 disposed in the chassis movably in an insertion/removal direction of the disk cartridge and movably in a direction toward or away from the chassis, the eject lever being rotated by being pushed by the disk cartridge 1 inserted into the holder; and cartridge drop preventive means 221 for preventing the disk cartridge 1 ejected by the eject lever 105 from dropping from the cartridge holder 102. The cartridge drop preventive means 221 is formed from a flat spring disposed on one side surface 102b of the holder and makes a sliding contact with one side surface 3b of the disk cartridge during unloading of the cartridge so as to give the disk cartridge a braking force. This arrangement can prevent the disk cartridge from jumping out and dropping off from the cartridge holder during ejection.

摘要： A disk recording/reproducing apparatus includes a chassis rotatably supporting a holder for storing a disk cartridge; an eject lever movably disposed in the chassis in an insertion/removal direction of the disk cartridge and movably in a direction toward or away from the chassis. The eject lever is rotated by being pushed by the disk cartridge 1 inserted into the holder. A cartridge drop preventive mechanism prevents the disk cartridge ejected by the eject lever from dropping from the cartridge holder. The cartridge drop preventive mechanism is formed from a flat spring disposed on one side surface of the holder and makes a sliding contact with one side surface of the disk cartridge during unloading of the cartridge so as to give the disk cartridge a braking force. This arrangement can prevent the disk cartridge from jumping out and dropping off from the cartridge holder during ejection.
