A shutter device with a shutter base plate having an aperture part and a protruding part. First and second shutter blade members are arranged to travel a predetermined movement distance and a distance shorter than the predetermined distance, respectively, over the aperture part. The second shutter blade member has a slot engaging the protruding part of the base plate. First and second arm members are pivotally supported by the shutter base plate and the second arm member supports the first and second shutter blade members in a swingable manner. The second arm member is also connected to the second shutter blade member, wherein the first shutter blade member and the second shutter blade member are caused to travel over the aperture part by the second arm being driven,

Shutter device

In a recording and/or reproducing apparatus, at least one of tape guiding members provided for wrapping a tape around a rotary drum pulls out the tape from a cassette before a cassette mounting member is moved in a direction of approaching the rotary drum and, after that, the tape guiding members and the cassette mounting member are moved in directions of approaching the rotary drum.

Recording and/or reproducing apparatus having tape guiding member

A tape loading device includes a guide member having a guide slot, a guide post for drawing tape from a cassette, and a slider which supports the guide post and has a shaft guided along the guide slot, the shaft having a stopper for preventing the shaft from coming off the guide slot, wherein a clearance between the stopper and the guide member differs on opposite sides of the guide slot.

Recording and/or reproducing apparatus including tape loading mechanism

A tape loading device includes first and second guides for performing a tape loading operation. First and second assemblies move the first and second guides. A control unit controls the speeds of the first and second assemblies to drive the first assembly at a predetermined speed and to vary the moving speed of the second assembly without varying the predetermined speed of the first assembly.

A recording and/or reproducing apparatus for recording or reproducing information on or from a tape has a loading mechanism having a plurality of links for drawing the tape out of a cassette. The plurality of links include a first and a second link rotatably coupled to each other, the first link being rotatably supported on the chassis, the second link having a tape guide member for drawing the tape out of the cassette and bringing it into contact with the head. At the start of the operation of the plurality of links, the second link is rotated while the first link is stationary.

Recording and/or reproducing apparatus having a tape loading mechanism

In a magnetic recording and reproducing apparatus for recording and reproducing information by pulling out a tape from a cassette by revolving a pair of tape pull-out members in opposite directions with a tape loading mechanism and by wrapping the tape around a rotary drum, a tape pull-out aiding member is arranged in combination with one of the tape pull-out members; and a differential mechanism is arranged between the tape pull-out aiding member and the tape pull-out member to cause the two members to revolve at different angles of revolution in such a way as to give a desired angle of inclination of the tape relative to the rotary drum. The differential mechanism is formed jointly by a slide member which is slidable in the direction of revolution, the tape pull-out aiding member being disposed at the slide member, and a positioning member which is arranged to lock the tape pull-out aiding member by restricting its movement in such a way as to cause two members to revolve at the different angles of revolution.

Magnetic recording and reproducing apparatus

A recording or reproducing apparatus wherein a first chassis to which a head is secured and a second chassis on which a recording medium is to be mounted are overlappingly disposed is arranged as follows: After a tape-shaped recording medium is mounted on the apparatus, when the tape moves toward the head according to an action of abutting the tape against the head, a force for moving the second chassis is applied to the inside of a plane defined by four points of four slide guide shafts on the second chassis. Further, the second chassis is arranged to be guided at two points which are diagonally located among the four points.

Recording or reproducing apparatus

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.

Rotary head drum unit with grooves or protrusions on a stationary drum

A cassette loading device having a cassette holding member arranged to be shiftable between a first position in which the cassette is attachable and detachable and a second position in which the cassette is stayed in a state of allowing use of a recording medium disposed within the cassette; to limit the movement of a cassette pushing member when the holding member is in the first position; and to remove the limitation when the holding member is in the second position.
