A recording and reproducing apparatus includes a guide post for pulling out a tape-shaped recording medium from a cassette and wrapping the tape-shaped recording medium around a rotary drum, a guide base which supports the guide post, the guide base being movable between a first position in which the cassette can be loaded and a second position in which a recording or reproducing action can be performed with the tape-shaped recording medium wrapped around the rotary drum at a predetermined angle, and an elastic member for, after the guide base moves from the first position to the second position, urging the guide base toward the second position to position the guide base at the second position. The elastic member is disposed on an upper surface of the guide base.

Recording/reproducing apparatus with reduced number of guides posts

A recording and/or reproducing apparatus for recording and/or reproducing data by drawing a tape from a cassette and winding the tape onto a rotating drum including a head, includes a non-rotatable inclined post for changing the position of the tape in a direction crossing the running direction of the tape and along the axis of the inclined post, and a tapered part disposed in the vicinity of an end of the inclined post, for restricting the position of the tape in a direction crossing the running direction by being in contact with the tape when the tape is loaded.

Recording and/or reproducing apparatus having an inclined guide post and tape guide restricting structure

Recording/reproducing apparatus with reduced number of guide posts

A magnetic recording and reproducing apparatus includes guide posts arranged to pull out a tape-shaped recording medium from a cassette and wrap the tape-shaped recording medium around a drum, guide members arranged to support the guide posts, arms arranged to move the guide members, and arm driving parts arranged to cause the arms to swing, wherein the arms and the arm driving parts are disposed respectively on different sides of a chassis.

Magnetic recording and reproducing apparatus

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.

An apparatus performs recording and/or reproduction of signals by a head of a drum with which a tape-like recording medium is brought into contact while being moved under a fixed tension from a reel engaging a supply reel base to a reel engaging a take-up reel base. An arm retains a tension post which presses against the recording medium, forming a predetermined path to detect a tension thereof. One end of the arm is pivotally supported, and the arm is urged by a spring so as to allow the tension post to elastically press against the recording medium. At least one end of a band brake for loading a braking torque on the supply reel base is locked to the arm. The locking points of both two ends of the band brake are at positions which are substantially symmetrical with respect to a perpendicular bisector of a line connecting a center of the supply reel base when a first recording tape cassette is used to a center of the supply reel base when a second recording tape cassette having a size different from that of the first cassette is used.

Recording and/or reproducing apparatus capable of using cassettes having

A camera includes a fixed first mirror for both reflecting a light flux and transmitting the light flux therethrough, a second mirror for reflecting a part of the light flux transmitted through the first mirror toward a particular device, the second mirror being capable of moving between a non-exposure position and a mirror-retracted position, and a light blocking member movable in interlocked relationship to a movement of the second mirror in such a manner that, when the second mirror is located at the non-exposure position, the light blocking member is located at a light blocking position at which the light blocking member blocks at least a part of the light flux transmitted through the first mirror, and, when the second mirror is retracted to the mirror-retracted position, the light blocking member moves to a retracted position at which the light blocking member is retracted from the light blocking position.

Light blocking apparatus for a camera

An apparatus for recording and/or reproducing information on or from a tape by drawing out the tape contained in a cassette and bringing the tape into contact with a head, has a chassis and a base which are integrally formed, a slider provided with a member for drawing out the tape, the chassis having a reference surface. The base is provided with a positioning portion for positioning the slider. The positioning portion has a side which is formed in substantially parallel with a virtual line perpendicular to the reference surface of the chassis, or which is inclined away from the virtual line in the direction away from the reference surface of the chassis.

Recording and/or reproducing apparatus having a tape loading device

An apparatus for recording and/or reproducing information on and/or from a tape drawn from a cassette includes first and second tape guide members for guiding the tape drawn from the cassette, the first tape guide member bringing the tape into abutment with the head, and a control mechanism for, during tape loading, causing the first tape guide member to travel in a direction in which the tape is brought into abutment with the head, and also causing the second tape guide member to travel toward the cassette.

Recording and/or reproducing apparatus with control mechanism for

A reel mount moving device for moving a reel mount to the position of each reel contained in each of a plurality of cassettes of different sizes, with any of the cassettes mounted, includes the reel mount which is arranged to be rotated by a power of a drive source for moving a recording medium, a converting member for converting the power of the drive source into a force of moving the reel mount, and a switching member arranged to cause the converting action of the converting member to be selectively turned on or off.

Recording and/or reproducing apparatus permitting selective use of

In a tape loading device for wrapping a tape member around a rotary drum to a given degree of angle by moving two guide posts in opposite directions along the rotary drum, a plurality of rail defining members define rail slots which are arranged to individually guide the two guide posts, and two joints between the rail defining members on both sides of each of the rail slots are disposed in positions deviating from each other to a distance which is longer than the length of the guide post in the longitudinal direction of the rail slot.

Tape loading device

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.
