A disc device includes a first cam gearhaving a cam groove, and engaged with and released from one gear of a power transmission system, and a second cam gearhaving a hole portioncorresponding to the cam groove, laid on the first cam gearand rotatably supported relative to the first cam gear, and engaged with and released from one gear of the power transmission system.

Disc device

A disc device has a sliding memberthat operates in response to a rotational force of the first partially toothless gearto disconnect a power transmission system from a disc conveying roller, and a protruding portiondisposed on this sliding memberis brought into contact with a rising portionof a rotary leverat an initial position of the sliding member before the sliding member starts operating, so as to restrict a rotation of the rotary leverin such a way that a pindoes not come into contact with a wall surface of a cam groove

A disc apparatus includes: a playback unitprovided with a conveying rollerand a disc guideto be vertically movable with respect to an apparatus main body; a moving means for moving downward the conveying roller and the disc guide in amounts of travel which are different from each other to avoid contact of the roller and the guide with a discwith interlocking an operation that the loaded discis moved downward to be mounted on a turntable; and a disc-guide-cum-position-regulating memberattached to the apparatus main body corresponding to a disc loading port such that the playback unit is restrained from moving to the disc loading port side.

Disc apparatus

A disk reproducing apparatus includes a disk detecting lever that has a switch abutting section and a light intercepting section and rotates according to the loading operation and the ejecting operation of a disk caused by abutment of the outer edge of the disk against a detecting pin; a single switch that is switched by the switch abutting section and thereby detects the loading start position, and also the inserting position of the disk; and a single photosensor that detects the inserting position of the disk with keeping the light intercepting condition thereof by either the light intercepting section or the disk and also detects the ejection end position when the light intercepting condition brought about by the disk has been released and then the light intercepting condition brought about by the light intercepting section is released.

Disk reproducing apparatus implementing detection of disk insertion condition for loading and ejection operations

A lever having an end rotatably supported by a rack is disposed, a long groove is formed in either another end of the lever or a base chassis and extends in a direction approximately perpendicular to a direction of transporting an optical pickup, a fulcrum member is disposed in either the base chassis or the other end and is rotatably and slidably engaged with the long groove, and to slide along the long groove when the optical pickup is transported, and a spring that always exerts a pushing force in a direction of rotating the lever with the other end being a fulcrum and with the end being a point of action to exert a pushing force of bringing the rack into contact a gear series upon the rack is disposed between a predetermined position of the base chassis and an intermediate position of the lever.

Optical disc device

A disk apparatus includes a plurality of stockers each for stocking a disk therein, a plurality of stocker moving mechanism arranged around the plurality of stockers, for, when stocking a disk in one of the plurality of stockers and when playing back a disk stocked in one of the plurality of stockers, moving the one of the plurality of stockers upward or downward, each of the plurality of stocker moving mechanism having small-diameter portions at upper and lower ends thereof, and an actuation member movably arranged in a gap between the small-diameter portion of one of the plurality of stocker moving mechanism and an inner surface of a wall of a housing.

Disk apparatus

A MD loading mechanism for a multidisk MD reproducing apparatus capable of storing a plurality of MDs and of reproducing information recorded on the plurality of MDs successively comprises: a plurality of cartridge holders for holding MD cartridges therein, respectively; a MD cartridge storage unit for storing the plurality of cartridge holders therein in a stack so that the back end surfaces of the MD cartridges held within the cartridge holders can be seen from outside, provided with a plurality of insertion slots through which the MD cartridges are inserted in the cartridge holders and cartridge holder locking means for locking the cartridge holders within the MD cartridge storage unit; and a cartridge holder transfer means for transferring the cartridge holder holding a desired MD cartridge from the MD cartridge storage unit to the MD reproducing apparatus. The contents of the MD cartridges stored in the MD cartridge storage unit can be known and the MD cartridges can be taken out or changed while the MD reproducing apparatus is in operation.

Disk reproducing apparatus

A disk device includes a lock mechanism for displacing the entirety of a playing section supported through a shock-absorbing member on an outer chassis towards a disk insertion mouth by the movement of a cam flap which performs loading and ejection operations and which forms a section of the playing section. The lock mechanism fixes and locks the playing section by pressing a portion of the playing section against a wall component of the outer chassis situated on a side of the disk insertion mouth.

Disk device

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 disk device is provided with an MD carrying mechanism which uptakes an MD , places the MD on a turntable, and performs the ejection of the MD from the turntable by the displacement of the holder drawing lever which forms part of a linking mechanism when the cartridge of the MD is inserted into an MD holder. The disk device also comprises a clamp lever avoidance mechanism which refuges the clamp lever , which is used for clamping the CD , to a position which does not interfere with the uptake and ejection of the MD during uptake and ejection of the MD by the MD carrying mechanism.

Disk device for disks having different sizes

A disk device is comprised of a CD conveying mechanism which performs the uptake and ejection of CDs by a conveying roller . An MD conveying mechanism drives a clamp lever rotating mechanism which performs the refuge of the clamp lever from an initial position and the return of the clamp lever to an initial position by being driven by a CD loading drive motor. A CD is clamped by a clamp mechanism when the CD is loaded onto a fixed position in the device and directed to a turntable. When an MD is loaded or ejected, the MD conveying mechanism drives the refuge or return of the clamp lever . The placement of an MD on a turntable is performed by an MD placing mechanism which is driven as a result of an MD being taken up to a fixed position in the device.

Disk device for loading and ejecting disks

A disk device comprises first and second disk selection projections which regulate an angle of the disk conveyed to a small or large disk positioning recess on the basis of an outer radius of the disk. The first and second disk selection projections have tapered faces provided at fixed intervals on a disk guiding face facing the conveying roller The disk device further comprises steps for positioning the small disk or the large disk having an angle regulated in accordance with the outer radius to the small disk positioning recess or to the large disk positioning recess

Disk device for disks of different sizes

A disk device is includes first support shaft which supports a retaining arm, retaining a second turntable, to reciprocate vertically and a second support arm which supports the retaining arm to rotate and refuge horizontally so that the second turntable which supports a second disk which is not stored in a cartridge and which transmits a rotational force to a second disk can be loaded and separated from a first turntable which supports a first disk and which transmits a rotational force to a first disk.

A disk device is comprised of a feed roller displacement mechanism which displaces a position of a feed roller to a position lower than a position when a CD is inserted. When a CD is ejected from the turntable, the position of the feed roller displaced downwardly is returned to an initial insertion position.
