Tape guide mechanism of magnetic recording reproducing device

A tape guide mechanism of a magnetic recording and reproducing apparatus that comprises a movable chassis having a tape guide arm member on which a tape guide is erected and a pair of reels stands thereon and a fixed chassis having a magnetic rotary head thereon, in which when said movable chassis moves to one position of said fixed chassis, loading and unloading of a cassette is performed and when said movable chassis moves to the other position, a magnetic tape is taken out from the reel of the loaded cassette to perform tape loading of said magnetic tape being wound around said magnetic rotary head, wherein

• after completing the tape loading, said tape guide is fixed to a predetermined position by a guide receiving member having a guide receiving portion that is provided on said fixed chassis to receive the tape guide,
• wherein, in the middle of said tape guide traveling to said predetermined position, said tape guide arm member is made to move along a groove provided in said fixed chassis to determine the position in the chassis plane direction, and
• wherein the tape guide arm member is guided and moved by contact between a projection provided on a lower surface of said tape guide arm member and a surface of the guide receiving member, to determine the position in the height direction.
