An acoustic reflector includes a reflection portion on which an elliptical reflection surface is formed, in which sound output from a speaker device that has an output position of the sound at or near one focal point on the elliptical reflection surface is reflected by the elliptical reflection surface, and the reflection portion has a size that reflects sound in a range of equal to or less than a nominal directional angle of the speaker device. As a result, because an outer shape of the reflection portion is formed to have a size in the range corresponding to the nominal directional angle of the speaker device, it is possible to reduce the size of the acoustic reflector.

Provided is a sound collecting device in which sound is favorably input to a sound collecting unit. The sound collecting device includes an attachment portion that has a sound collecting unit attached and is adapted to be inserted into an external ear canal, a holding portion adapted to be inserted into the external ear canal and hold the attachment portion at a predetermined position in the external ear canal, and a wearing portion that is positioned on an opposite side of the attachment portion while interposing the holding portion and adapted to be at least partly engaged with an auricle, in which the attachment portion and the holding portion do not block the external ear canal and have acoustic transparency. Further, the attachment portion and the holding portion are positioned in the ear in a state of not blocking the external ear canal.

A recording and/or reproducing apparatus for recording and/or reproducing information signals with the use of a tape cassette having a pair of tape reels which are engaged on reel shafts of the apparatus includes a tape cassette transfer mechanism for shifting the tape cassette inserted by way of a cassette insertion opening in a first direction normal to the reel shafts and then parallel to the reel shafts to place the pair of tape reels within the tape cassette on the shafts. The apparatus includes a drive arrangement having a single motor that drives both a cassette transfer arrangement and a movable tape loading control arrangement which is disposed in the apparatus for extracting a portion of the tape of the cassette and guiding an extracted portion of the tape along a predetermined path.

A loading device for a disc-shaped recording medium, such as an optical disc, includes a recording/reproducing unit, a loading member, a transport mechanism, a control mechanism and a chuck mechanism. The recording/reproducing unit has a rotating driving mechanism for rotationally driving the disc-shaped recording medium and a head for recording and/or reproducing information signals on or from the disc-shaped recording medium. The loading member is arranged facing the recording/reproducing unit on the chassis for movement along the chassis surface. The transport mechanism transports the disc-shaped recording medium introduced into the apparatus as far as the recording/reproducing unit. The control mechanism releases the disc transport operation by the transport mechanism by the loading member being moved on the chassis. After the transport operation of transporting the disc-shaped recording medium by the transport mechanism is discontinued by the control mechanism, the chuck mechanism chucks the disc-shaped recording medium transported by the movement of the loading member on the chassis in cooperation with the rotating driving mechanism of the recording/reproducing unit.

Shifting device and loading device for disc-shaped recording medium

A recording and/or reproducing apparatus for recording and/or reproducing information signals with the use of a tape cassette is provided with a pair of reel shafts, each having an engaging member mounted with a bias towards the end of the supporting shaft, and a tape cassette transfer mechanism adapted for shifting the tape cassette inserted by way of the cassette inserting opening in a first direction normal to the reel shafts and guiding or loading the tape cassette for inserting and engaging the reel shafts with a pair of tape reels within the tape cassette. When at least the tape cassette transfer mechanism is set at a position facing the cassette inserting opening, the tape cassette transfer mechanism abuts an end of each of the reel engaging members to shift the members to a retracted position while the tape cassette is moved by the tape cassette transfer mechanism towards the proximal side of the reel shafts, to reduce the displacement in the second direction of the tape reel of the tape cassette by the tape cassette transfer mechanism to a value less than the thickness of the tape cassette to reduce the thickness of the apparatus. After completion of the tape cassette loading by the tape cassette transfer mechanism, the tape cassette is partially exposed to the cassette inserting opening to prevent a second tape cassette from being introduced into the cassette inserting opening after completion of loading of the first-mentioned cassette.

When a large diameter disc is inserted into the disc drive, diameter sensing probes detect the large diameter and unlock movable disc guides and subsequently induce the guides to separate to levels wherein passage of the large diameter disc is facilitated. The guides are locked in a manner which prevents the same from returning to the positions suited for guiding small diameter discs until such time as the large diameter disc is unloaded from the device. Levers mounted in the drive respond to the diameter of the disc loaded and assume configurations relative to the diameter of the loaded disc. The levers are locked in a configuration suited for small discs until such time as a large disc is introduced. At this time the levers are unlocked. A locking mechanism senses the peripheral edge of the disc and hold the arrangement in a configuration suited for the larger diameter.

Disc drive arrangement for CD player and the like capable of loading

An optical disk player wherein a chassis having an optical pickup, a disk table and the like mounted thereon is supported by a frame using elastic support means at a plurality of positions, a vessel filled with a viscous fluid and sealed is provided at either the frame or the chassis, and a movable member provided at the other of the two is arranged in the sealed viscous fluid. With this arrangement, the slope of the Q curve in the resonant region is moderate enough to improve the antivibration characteristics, thus substantially eliminating sound omissions.

A disc loading apparatus for use in a disc player comprises an arm device supported by a stationary structure to be movable for loading a disc carried to a predetermined position on a disc rotating device mounted on a chassis supported by a resilient supporting member engaging with the stationary structure and unloading the disc from the disc rotating device, first and second rollers for carrying the disc to the predetermined position, and a locking mechanism provided between the chassis and the stationary structure for locking the chassis to be substantially fixed to the stationary structure in response to the movement of the arm device for disc loading or disc unloading.

Disc loading apparatus for use in a disc player

A compact disc player is disclosed, in which in order to protect a disc from being dirtied and damaged upon unloading and loading, at least a pair of rollers for holding therebetween and transporting a disc inserted thereinto are each formed to be of such a taper-shape that the diameter of each roller is made small at the central portion thereof and is gradually increased therefrom to both side portions thereof, thus each roller being in contact only with the peripheral edge portion of the inserted disc.
