A speaker unit includes: a speaker that contains a magnet for vibrating a diaphragm to output sound; a speaker housing unit that houses the speaker so that the front of the diaphragm is exposed outside; an opening-and-closing unit that is attached to the speaker housing unit so that the opening-and-closing unit can both open, with respect to the speaker housing unit, to expose the front of the diaphragm outside and close to cover the front of the diaphragm; and a metallic component that is, when the opening-and-closing unit is closed with respect to the speaker housing unit, attracted to the magnet of the speaker to pull the opening-and-closing unit in a closing direction.

Speaker unit and audio output robot device

A recording and/or reproducing apparatus has a disk transfer mechanism, a mechanical chassis lifting/lowering mechanism, and a gear switching mechanism. The disk transfer mechanism transfers a disk onto a disk table with a motor. The disk transfer mechanism has a rotation transmitting assembly having a gear train including a swing gear and another gear. The mechanical chassis lifting/lowering mechanism lifts and lowers a mechanical chassis with respect to the disk, which is transferred onto the disk table by the disk transfer mechanism. The gear switching mechanism brings the swing gear out of mesh with the other gear of the gear train after the disk is transferred onto the disk table by the disk transfer mechanism, thereby preventing the disk transfer mechanism from being actuated by the motor, and actuating the mechanical chassis lifting/lowering mechanism with the motor. After the disk is transferred onto the disk table by the disk transfer mechanism, the motor having actuated the disk transfer mechanism actuates the mechanical chassis lifting/lowering mechanism.

Disk recording and/or reproducing device

A structure on a base plate is simplified, and the thickness of the structure on the base plate is reduced. A disk transfer mechanism includes a housing having a disk slot. A disk is inserted from the disk slot between a base plate and a top panel of the housing. A disk transfer mechanism has a motor and a rotation transmitting assembly for transmitting rotation of the motor to the transfer rollers. The disk transfer mechanism rotates the transfer rollers to transfer the disk onto a disk table. The rotation transmitting assembly includes a base-plate rotation transmitter disposed on the base plate and a top panel rotation transmitter disposed on the top panel. Thus, the components of the rotation transmitting assembly are distributed on the base plate and the top panel.

Disk recording and/or reproducing apparatus

A plurality of switches are pressed by a single switch operating member. A disk recording and/or reproducing apparatus has a switch mechanism operable when a pair of turn arms is turned so as to be spread away from each other by a disk inserted from a disk slot. The switch mechanism includes a plurality of switches, a rotary cam rotatable in ganged relation to angular movement of the turn arms, and a switch operating lever interposed between the rotary cam and the switches for successively pressing the switches in response to rotation of the rotary cam.

A disk recording and/or reproducing apparatus has a disk centering member having a disk abutment assembly and an operating member, and angularly movably supported at a portion thereof between the disk abutment assembly and the operating member by a shaft, wherein when a transferred disk abuts against the disk abutment assembly to press the disk abutment assembly, the disk centering member is angularly moved about the shaft, and then prevented from being angularly moved by a stopper, centering the disk, and a gear switching mechanism operable by being pressed by the operating member. The disk abutment assembly has a first disk abutment for angularly moving the disk centering member by a predetermined angular interval, and a second disk abutment for angularly moving the disk centering member by an angular interval, which is substantially the same as the angular interval of the first disk abutment.
