A loading mechanism by which a disk cartridge can be loaded into a disk drive apparatus includes a mechanism for opening and closing a shutter of the disk cartridge; an elevating plate on which a spindle motor and an alignment pin for positioning the cartridge are mounted; and an oblique surface for moving the elevating plate onto the cartridge side for cartridge insertion. In one case, a front end portion of a first alignment pin is elliptically cylindrical, and only a front end portion of a second alignment pin is curved. The second alignment pin is offset onto the rear side of the apparatus. In another embodiment, a shutter sliding member includes: first and second sliding pieces which slide in a guide groove of a guide frame forming an insertion passage of the cartridge; and a torsion spring. In the first and the second sliding pieces, a shaft portion engages one end of the torsion spring, and a flange interposes the guide groove. In a third embodiment, the elevating plate has two sets of guide pins arranged perpendicularly to the cartridge inserting direction, symmetrically with each other, and the load plate of the elevator has two oblique surfaces on the right and two oblique surfaces on the left which receive the guide pins and pull up the guide pins when the load plate is moved, and starting positions of these oblique surfaces are shifted in the longitudinal direction.

An optical storage device including a light source mounted on a base, an optical head having an objective lens for focusing light from the light source onto an optical recording medium, a spindle motor, and a spindle motor assembly having the spindle motor and movable between a raised position where the spindle motor engages the optical recording medium inserted in the optical storage device and a lowered position where the spindle motor disengages the optical recording medium. The optical storage device further includes a link mechanism for moving the spindle motor assembly between the raised position and the lowered position according to insertion and ejection of the optical recording medium with respect to the optical storage device, and a stopper for engaging the link mechanism to prevent movement of the link mechanism when the optical recording medium is not inserted in the optical storage device, thereby preventing movement of the spindle motor assembly to the raised position.

Mechanism for loading disk into disk drive apparatus

An optical disk drive has an inserting/ejecting mechanism for performing an insertion and ejection of either a CD mounted on a CD carrier or an MO cartridge and a recording and reproducing mechanism for reading or reproducing with either medium. The inserting/ejecting mechanism has a load mechanism which is activated when a CD and a CD carrier on which the CD has been mounted or a medium as an MO cartridge are inserted in an inserting/ejecting port and moves the medium to the position of a spindle motor for attachment to a motor rotary shaft. In addition, an ejecting mechanism, which is activated on the basis of a medium ejecting instruction, moves the medium to an ejecting position of the inserting/ejecting port after the medium was removed from a spindle motor.

Optical disk apparatus for using multiple types of disks

A printing apparatus includes a printing head for printing on a bank book, a platen disposed opposite the printing head, and a cam mechanism for moving the platen. A sensor detects the thickness of the bank book which is between the printing head and the platen, and a sensor moving mechanism moves the sensor toward or away from the platen. A controller controls the operation of the cam mechanism and the sensor moving mechanism as the sensor is moved to a measuring position approaching the printing head. The printing head is moved toward the platen according to a detected value and then the sensor is retracted from the measuring position. As a result, after moving the printing head, the sensor does not contact the surface of the bank book, and therefore does not produce jamming or oblique feeding of the bank book during a line feed or printing operation.

A printer having a bail roller opening and closing apparatus including a bail roller for pressing a printing medium against a platen, a bail roller opening and closing mechanism for moving the bail roller between a closed position and an open position, and a clutch for connecting a space motor to the bail roller opening and closing mechanism. The bail roller opening and closing mechanism includes a rotating member rotationally driven by the space motor via the clutch, a transmission member causing the bail roller to be displaced by displacement of the transmission member and manual displacement of the bail roller, and a bidirectional motion transmission mechanism for transmitting bidirectional motion between the rotating member and the transmission member.

A printer having an ink ribbon shift apparatus includes a carrier unit having a printer head and a ribbon guide which is movable upwardly and downwardly. Up and down shift means are provided to shift an ink ribbon cassette up and down. A shaft is disposed parallel to a platen and extends along the entire range of movement of the carrier unit. The shaft shifts up and down together with the ink ribbon cassette and is engaged with the said ribbon guide. The up and down shift means moves the ink ribbon cassette up and down and the ribbon guide is thereby shifted up and down via the shaft so that a predetermined color band of an ink ribbon is positioned on a printing line.
