A flat-panel display apparatus comprises a display panel, a circuit board, and a cover. The circuit board includes a first and second circuit boards. The first circuit board is arranged above the second circuit board so that, on the back side of the display panel, a mounting surfaces of the first and second circuit boards are approximately in parallel with a display surface of the display panel and do not overlap each other. Each of the first and second circuit boards have a primary mounting surface on which a large number of electrical components are mounted, and a secondary mounting surface that is opposite the primary mounting surface. The primary mounting surface of the first circuit board is arranged in an inverted orientation to the primary mounting surface of the second circuit board. A radiator with fins is provided on the secondary mounting surface side of the first circuit board.

A cassette loading apparatus includes a holder arranged to hold a cassette, and a link mechanism arranged to support the holder with a plurality of levers in such a way as to allow the holder to ascend and descend between an ascended position and a descended position with respect to a chassis. The link mechanism includes a pair of levers which are disposed respectively on two opposite sides of the holder, and the pair of levers are formed integrally with each other through a connection part arranged above an upper part of the cassette.

Cassette loading apparatus

A cassette mounting device comprises a cassette holder into which to insert a cassette, a pair of link mechanisms disposed on lateral opposed sides of the cassette holder so that the cassette holder is supported for upward and downward movement with respect to a chassis, and a fixing member which fixes each of the pair of link mechanisms to the chassis, the fixing member clamping each of the pair of link mechanisms turnably with respect to the chassis.

Recording and/or reproducing apparatus including cassette mounting device

A cassette mounting device includes a cassette holder for receiving a cassette, a pair of link mechanisms disposed on lateral opposed sides of the cassette holder so that the cassette holder is supported for upward and downward movement with respect to a chassis, a lock lever which locks the cassette holder at a down position thereof and a spring which urges said lock lever to turn, the spring being disposed inside of the cassette holder in a gap between the cassette and the cassette holder.

A signal recording apparatus is arranged to record main information in a first area provided in each of a multiplicity of parallel tracks formed on a tape-shaped recording medium, and an index signal in a second area of each of a predetermined number of continuous tracks, the second area being provided separately from the first area within each of the multiplicity of parallel tracks. The apparatus records, as the index signal, first index information in a first section within the second area of each of the predetermined number of continuous tracks, with either one of binary data being repeated continuously during a period corresponding to the first section, and second index information in a second section within the second area of each of the predetermined number of continuous tracks, the second index information including track data indicative of relation to a specific track among the predetermined number of continuous tracks. In the above-described arrangement, it is possible to increase the speed of search for a specific track by using the first index information and to improve the accuracy of search for the specific track by using the second index information.

Device and method for recording and reproducing image information

A cassette mounting device is arranged to hold a cassette with a cassette holder and to support the cassette holder to be movable upward or downward relative to a chassis between raised and lowered positions. X-shaped links are disposed on both sides of the cassette holder and shaft pin parts of two interconnected levers are arranged to be slidable in a state of engaging cam slot parts of the chassis on the sides where these levers are mounted on the chassis. The cam slot parts are formed aslant, at least at their parts corresponding to the raised and lowered positions of the cassette holder, at such an angle of inclination that the shaft pin parts relatively move upward when the cassette holder descends.

Information signal recording device for recording main information

In a clutch mechanism formed by adhering a friction member to a face of one of a pair of rotating elements with an adhesive member and arranged to bring the surface of the other of the pair of rotating elements into pressed contact with the friction member by an urging member, a recessed part is formed in the face of the one of the rotating elements to which the friction member is adhered, so as to accumulate and retain pressure sensitive adhesive seeping from the adhesive member.

Recording and/or reproducing apparatus having clutch mechanism

In a cassette mounting device arranged to cause a cassette which contains a tape-shaped recording medium therein to move between its mounting position and a position in which information is recorded or reproduced on or from the recording medium, a holder for holding the cassette is provided with a hatch part and an aperture part which is arranged to be formed by removing the hatch part from the holder, the aperture part being arranged such that the cassette can be taken out, if necessary, from the holder through the aperture part without damaging the recording medium.

Cassette mounting device having cassette removal facility additional to

In a recording or reproducing apparatus arranged to carry out recording or reproduction of a signal while keeping a magnetic tape wrapped around a rotary head drum equipped with a head, the upper cylinder of the rotary head drum is provided with a rotor core which constitutes part of a rotary transformer for carrying out signal exchange between the head and an external circuit. An elastically deformable contact is held by a holder secured to the rotor core, and includes a plurality of conductive portions, each conducting electricity between opposed faces of the elastically deformable contact, and a cutout defined in a middle portion thereof. The elastically deformable contact is pressed from opposed sides between a conductive pattern connected to the magnetic head and a conductive pattern connected to the rotor core so that it can be brought into pressure contact with both of the conductive patterns, thereby providing electrical conduction between the head and the rotor core.

Rotary head drum having a connecting member for providing electrical

Apparatus for recording or reproducing signals on a magnetic recording tape by wrapping the tape around a rotary drum unit of type including a stationary drum and a rotary drum supported by the stationary drum is provided with grooves which are formed in the stationary drum, the grooves being deeper than the depth of surface coarseness of the stationary drum and being located adjacent a point at which the tape parts from the stationary drum when the tape travels for recording or reproduction.
