A supplementary roller is disposed on the end of a disk guiding section so that the outer face of the cylindrical shaped section of the supplementary roller is placed on the conveying roller side by the protruding section formed on disk guiding section

Disk unit with rollers

A disc device having a floating base supported by a chassis through a plurality of elastic members, a holder which is supported on the floating base so as to be able to move vertically with respect to the floating base, and into which a disc cartridge is inserted, a slider, slidably disposed so as to move in directions of inserting and discharging a disc cartridge into and out of the disc device, for holding and carrying a disc cartridge inserted thereinto, and a driving arm, one end part of which is rotatably supported on an axis, and another end part of which can be engaged with the slider for inserting and discharging the disc cartridge. Furthermore, the device having a pair of slide plates slidably fixed on the chassis, for securing the floating base to the chassis and for releasing the floating base from the chassis, a pair of links for sliding the pair of slide plates, and a rotary member for rotating the driving arm so as to drive the slider and for driving the pair of links.

Disc recording and reproducing apparatus having a drive mechanism for

A disc device including a floating base supported by a chassis through a plurality of elastic members, a holder which is supported on the floating base so as to be able to move vertically with respect to the floating base, and into which a disc cartridge is inserted, a slider, slidably disposed so as to move in directions of inserting and discharging a disc cartridge into and out of the disc device, for holding and carrying a disc cartridge inserted thereinto, and a switch lever, pivotably supported on the holder, for detecting that a disc cartridge is inserted correctly. A shutter opener slidably is disposed on the holder so as to be able to slide in directions of inserting and discharging the disc cartridge into and out of the holder, the shutter opener having a pair of grooves engaging pins fixed to said holder, the shutter opener having a projecting portion for opening a shutter of the disc cartridge carried by the slider.

Disc cartridge loading and unloading apparatus with shutter opening

A disc device including a floating base supported by a chassis through a plurality of elastic members, a holder which is supported on the floating base so as to be able to move vertically with respect to the floating base, and into which a disc cartridge is inserted, a slider, slidably disposed so as to move in directions of inserting and discharging a disc cartridge into and out of the disc device, for holding and carrying a disc cartridge inserted thereinto, and a switch lever, pivotably supported on the holder, for detecting that a disc cartridge is inserted correctly. The slider comprises a wrong-insertion preventing lug projecting inwardly from the slider, which can be engaged in a groove formed on one edge of a disc cartridge when the disc cartridge is inserted into the holder, and the switch level has a free end portion which is positioned outside a free end part of the wrong-insertion preventing lug.

Disc cartridge loading and unloading apparatus

A disc device including a floating base supported by a chassis through a plurality of elastic members, a holder which is supported on the floating base so as to be able to move vertically with respect to the floating base, and into which a disc cartridge is inserted, a slider, slidably disposed so as to move in directions of inserting and discharging a disc cartridge into and out of the disc device, for holding and carrying a disc cartridge inserted thereinto, and a switch lever, pivotably supported on the holder, for detecting that a disc cartridge is inserted correctly. A holder is rotatably engaged with the holder arm and accepts a disc cartridge inserted thereto, wherein when replaying the disc cartridge held in the holder, the disc cartridge is loaded onto the floating base by rotating the holder with respect to the holder arm and rotating the holder arm with respect to the floating base.

Disc cartridge loading and unloading apparatus with a holder and holder

A disc device comprises a floating base supported by a chassis through a plurality of elastic members, a holder which is supported on the floating base so as to be able to move vertically with respect to the floating base, and into which a disc cartridge is inserted, a slider, slidably disposed so as to move in directions of inserting and discharging a disc cartridge into and out of the disc device, for holding and carrying a disc cartridge inserted thereinto, a turn table disposed on the floating base and rotationally driven by a motor, onto which a disc accommodated within the disc cartridge is loaded, an optical pickup disposed in the floating base, for reading information from the disc which is rotated by the turn table, and a protrusion projecting from the slider to the floating base, the protrusion being brought into contact with the floating base, when the slider undergoes displacement toward the floating base, so as to prevent the slider from coming into contact with either the turn table or the optical pickup.

Disc device with slider contact prevention mechanism

A disk device includes a chassis, a replay unit for supporting a disk placed within the chassis, rotating the disk, and reading data from the rotating disk, a vibration-isolating unit for holding the replay unit by connecting the replay unit to the chassis and for isolating the replay unit from vibrations, a carrying unit for carrying the disk between a disk inlet and outlet formed on the chassis and a replay position where the disk is to be fixed in the replay unit, a motor for driving the carrying unit, and a flexible printed circuit (FPC). The FPC is mounted to one lateral surface of the motor and is electrically connected to the motor. The FPC has a projecting portion which projects from an upper surface of the motor toward one surface of the disk fixed in the replay unit. The projecting portion of the FPC is adapted to be brought into contact with the disk to prevent the disk from coming into contact with the motor when the disk moves closer to the motor.
