摘要： A lens barrel (3) comprises a drive frame (30) and a first lens frame (50). The first lens frame (50) has first to third cam followers (54a to 54c) that are respectively inserted into first to third outer cam grooves (34a to 34c), and first and second auxiliary pins (55a and 55b) disposed so as to be able to come into contact with first and second auxiliary grooves (35a and 35b). When viewed in the Y axis direction, the first and second auxiliary pins (55a and 55b) are disposed between the first to third cam followers (54a to 54c) in the peripheral direction. The positions of the first and second auxiliary pins (55a and 55b) are offset from the positions of the first to third cam followers (54a to 54c) in the Y axis direction.

摘要： The invention is concerned with a magnetic recording/playback apparatus in which a magnetic tape is pulled out from a tape cassette and wound around a cylindrical rotary head cylinder, having a rotary head built therein, over a predetermined angle to record/playback signals through the rotary head, and more particularly, with a tape guide post driving mechanism, a pinch roller pressing mechanism and a tension servo mechanism. Specifically, the invention provides a tape guide post driving device which can reduce the size, weight and thickness of the apparatus by ensuring a large angle of rotation of a rotating member, which includes a tension arm, in a direct manner. Also, the invention realizes a pinch roller pressing mechanism in which a sufficient stroke can be obtained even when a cam gear is reduced in its diameter and can provide a sufficient stroke even with a small amount of rotation. Further, the invention prolongs the service life and achieves a remarkable reduction in both the number of parts used and the number of assembling steps by using a pad brake (brake member), instead of a band brake, for braking a rotating member and bringing the brake member into full contact over the former's entire surface with the member being braked.

摘要： A magnetic recording and reproducing apparatus which allows a reduction in the necessary space by attaching a rotary head cylinder unit (5) onto a chassis 6 through leaf springs (23) using set screws (22). The rotary head cylinder unit (5) can be fixed onto the chassis (6) with a certain load without causing distortion of the rotary head cylinder unit. Integration of two or more leaf springs (131) improves efficiency in assembling the apparatus and reduces the number of components.
