It includes a knob including: an operation portion comprised of a ring-shaped conductive material, a rotational operation being performed on the operation portion; a rotary supporting member comprised of a ring-shaped non-conductive material and fixed onto a capacitive type touch panel, for rotatably supporting the operation portion; a ring-shaped concave groove disposed in the rotary supporting member; and a conductive conducting terminal portion electrically connected to the operation portion and rotating inside the concave groove integrally with the operation portion, the position of the conducting terminal portion being detected by the touch panel, wherein the conducting terminal portion is comprised of a plurality of conducting terminal portions, surfaces of the conducting terminal portions being in contact with the concave groove, at least two of the surfaces of the conducting terminal portions being different in contact area from each other.

Knob and input device

It includes: an operation portion comprised of a ring-shaped conductive member, a rotational operation being performed on the operation portion; a rotary supporting member comprised of a ring-shaped non-conductive member and fixed onto a capacitive type touch panel, the rotary supporting member rotatably supporting the operation portion; a ring-shaped concave groove disposed in the rotary supporting member; and conductive conducting terminal portions electrically connected to the operation portion, the conductive conducting terminal portions being rotated inside the concave groove integrally with the operation portion, positions of the conducting terminal portions being detected by the touch panel, wherein the operation portion is divided into a plurality of areas electrically insulated from each other in a circumferential direction, and at least two of the conducting terminal portions are mounted to different areas of the plurality of areas.

A cam projection sliding in a cam slot of an arm causes the arm to proceed to an arm when a shutter is in the closed position or the open position and to recede from the arm when the shutter is sliding between the open position and the closed position. A spring is thereby considerably displaced, providing a satisfactory operation of the shutter.

Media playback apparatus and shutter mechanism

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

The disk apparatus according to the present invention includes a tray which is elevationally movably disposed within a casing of apparatus integrating a disk reproducing system mechanism and holds a disk to be reproduced thereon, and the tray is provided with a disk supporting section supporting the peripheral edge of the disk such that the recording surface of the disk is floated on the tray.
