    摘要： An optical lens moving mechanism for zoom lens systems using a plane cam is disclosed. A lens system having an optical axis comprises at least two lens groups. A first lens holder and a second lens holder which respectively hold the two lens groups are moved along a guide parallel with the optical axis by a rotational movement of the plane cam which moves on a plane parallel with the optical axis, to zoom the lens system. The mechanism further includes a zooming motor, a position detector, and a controller to control the rotation of the motor, according to the zooming position of the lens system, to achieve a uniform zooming speed.

    摘要： A magnetic tape carrier has a supply reel and a take-up reel on which a magnetic tape is wound, a tape guide for guiding the tape from the supply reel to the take-up reel, a first reel mount on which the supply reel is rotatably mounted, a second reel mount on which the take-up reel is rotatably mounted, and a holder for movably supporting the first mount and second mount. The magnetic carrier can thus be used for various magnetic tape apparatus having different distances between the reel drive shafts of the supply reel and the take-up reel.

    摘要： A tape cassette adapter has a compact cassette, the magnetic tape of which is drawn out of the compact cassette by the movement of a tape drawing member from an inoperative position to an operative position due to movement in a single direction by a slide member. The tape is wound back onto a take-up reel of the compact cassette by a rotating member due to movement of the slide member in the reverse direction, while the tape drawing member returns from the operative position to the inoperative position.

    摘要： A tape cassette adapter which is useful for a tape recording and/or reproducing apparatus such as a video tape recorder and draws a tape out of a compact cassette by the movement of a tape drawing mechanism from an inoperative position to an operative position. The tape cassette adapter comprises an engaging member which engages to rotate synchronously with a take-up reel drive shaft of the standard size magnetic tape cassette apparatus, a take-up reel drive mechanism for rotating the take-up reel of the compact cassette, and a joint mechanism of rotational power transmission between the rotational member and the take-up reel drive mechanism. Consequently the tape cassette adapter is able to be mounted on apparatuses smoothly, even if the position of the take-up reel drive shaft deviates from a standard position.
