A cassette loading device for a cassette recording/reproducing apparatus includes a cassette tray reciprocably movable between a first position in which the cassette tray is retracted into a body of the recording/reproducing apparatus for loading a cassette in a predetermined position, and a second position in which the cassette tray is ejected forwardly from the front panel of the body for attachment and detachment of the cassette relative to the cassette tray, a holder disposed in the cassette tray for holding the cassette, and a mechanism responsive to the movement of the cassette tray toward the second position for causing the holder to tilt its forward end upwardly.

Tray-type cassette loading compatible with two different sized cassettes

A guide drum has recording or reproducing heads and a loading device has vertical poles and inclined poles for pulling out a tape from a tape cassette mounted on the recording/reproducing apparatus and for wrapping the tape around the guide drum. The loading device includes a pole driving mechanism for driving the poles and a toggle mechanism for causing a pinch roller to come into contact with a capstan so that the tape is interposed therebetween after the tape is wrapped around the guide drum. The toggle mechanism comprises a pinch roller cam driven in accordance with the movement of the pole driving mechanism, a pinch roller arm having the pinch roller and rotatably supported at one end portion and a link member coupled between the pinch roller cam and the pinch roller arm. With this arrangement, the pinch roller is directed to the capstan in response to the movement of the link member due to the movement of the pole driving mechanism.

Drive mechanism for cassette-enclosed magnetic tape

Disclosed is a magnetic recording/reproducing apparatus including a guide drum having at least one recording/reproducing head and a loading mechanism for pulling out a tape from a tape cassette mounted on the recording/reproducing apparatus and for wrapping the tape around the guide drum. The loading mechanism includes first and second loading devices each having a vertical rotatable pole and an inclined pole and the first and second loading devices are engaged with first and second guide grooves and are moved along the first and second guide grooves. At least one of the first and second guide grooves is branched in the vicinity of the loading termination position into two branch grooves so that the inclined pole of the corresponding loading device is substantially and angularly displaced with respect to the vertical rotatable pole by a predetermined angle in the vicinity of the loading termination position as said vertical rotatable pole reaches said loading termination position so as to form a predetermined tape path.
