摘要： An iris drive mechanism has two slidable diaphragms which are operatively connected with a motor through a lever arrangement which, for a given motor output shaft rotational speed moves the diaphragms slowly at their extreme positions wherein the aperture is small and large respectively, and more quickly at an intermediate stage. The slower movement when the aperture is small improves the F number resolution.

摘要： In a rotary head drum device for use in a video tape recorder or the like, a motor is provided between a rotating drum and a fixed drum. A drum base has at least three supporting surfaces for supporting the head drum. The supporting surfaces are formed at positions substantially equally spaced from a center of a rotating shaft fixed to the rotating drum and substantially equally spaced from each other. A single screw for fixing the fixed drum to the drum base is threaded into the fixed drum in the vicinity of the rotating shaft. With this construction, quality can be improved, and cost can be reduced.

摘要： A tape cassette loading system for wrapping a magnetic tape about a magnetic rotary head drum of a recording and/or reproducing apparatus is provided. The loading system includes two tape guiding elements for withdrawing the tape from a tape cassette towards the rotary head drum and their tape guiding track members provided around the drum in order to define tape loading paths. One of the tape loading path slopes downwardly from a loading stand-by state position. The other tape loading path slopes upwardly from the loading stand-by state position. The movement of the two guiding elements traveling in their loading paths allows the tape to be wrapped helically about the drum. The height drum may therefore be reduced and the recording and/or reproducing apparatus can be made smaller.
