To produce a subject's image on an imager as accurately as possible, a technique that is effectively applicable to the process of assembling an optical system is provided.An imaging device includes: an imager; a plate member, to which the imager is attached; and a holding member configured to hold the plate member. The plate member has a first portion, through which at least one fixing hole has been cut, and a second portion, to which the imager is attached and through which at least one adjusting hole has been cut. The plate member is held by the holding member using a number of fastening members to be introduced through the at least one fixing hole and the at least one adjusting hole. When the first portion is fixed on the holding member, the fastening member that is introduced through the at least one adjusting hole adjusts the relative position of the second portion to the holding member.

An image stabilizing device of the present invention includes: a correction lens holding member 405 to which a correction lens G3 included in an optical system of a camera is fixed; a holding member 408 that holds the correction lens holding member so that the correction lens holding member is movable in a rectilinear direction that is an arbitrary direction in a plane orthogonal to an optical axis A of light entering the correction lens G3 and in a rotation direction along an arc in the plane about a rotary shaft A3 substantially parallel to the optical axis A; a driving portion for rectilinear movement 412 that applies a driving force to the correction lens holding member 405 in order to drive the correction lens holding member 405 in the rectilinear direction; and a driving portion for rotation 413 that applies a driving force to the correction lens holding member 405 in order to drive the correction lens holding member 405 in the rotation direction. According to this configuration, it is possible to provide an image stabilizing device that achieves miniaturization, while preventing a deterioration in image stabilizing performance, and a camera including the same.

A magnetic recording and reproduction apparatus includes an arm section pivotable about a pivoting shaft; a tape guide section provided on the arm section for guiding a magnetic tape; a capstan section for driving the magnetic tape so as to run; and a maintaining section provided on the capstan section. The arm section is pivotable between a first location and a second location. The first location is a location at which the information recording to and/or information reproduction from the magnetic tape is possible. The second location is a location at which the information recording to and/or information reproduction from the magnetic tape is not possible. When the arm section pivots from the second location to the first location, the maintaining section maintains a relative position of the arm section, which is in the first location, to the capstan section.

A magnetic recording/reproducing device of the present invention records information on or reproduces information from a tape provided in a cassette by winding the tape around a rotary head cylinder at a prescribed angle after the tape is drawn out from the cassette including a supply reel and a take-up reel by tape guide members. The device is characterized in that: a first tape guide member is located downstream in the tape running direction with respect to the supply reel; the first tape guide member is followed by a second tape guide member, a third tape guide member and the rotary head cylinder; and only the first tape guide member, the second tape guide member and the third tape guide member are provided between the supply reel and the rotary head cylinder.

Four load lock chambers 2, 2′, 2″, 2′″ and eight process chambers 101, 102, 103, 104, 105, 106, 107 and 108 are hermetically connected around the outside of a central separation chamber 3 via gate valves 5—both types of chambers being stacked up in two places—and each chamber is capable of being evacuated by its respective vacuum pump system 301, 201 and 100. A transfer mechanism 42 inside separation chamber 3 removes a substrate 9 from a load lock chamber 2, 2′, 2″, 2′″ transports it to each of the process chambers 101, 102, 103, 104, 105, 106, 107 and 108 in a prescribed sequence and thereafter returns it to load lock chamber 2, 2′, 2″, 2′″. Each load lock chamber 2 has inside it a substrate holder which always holds a single substrate 9 in the same position.
摘要:
A magnetic recording/reproduction apparatus of the present invention, which records/reproduces information on/from a magnetic tape by passing the tape around a rotary head cylinder having a rotary head for a predetermined arc, includes: a capstan shaft; a pinch roller; a first reel base rotatably attached to a shaft; a second reel base rotatably attached to a shaft; and an idler supported swingably to swing to the second reel base when the capstan is rotated in a first direction and to the first reel base when the capstan shaft is rotated in a second direction, wherein the idler includes a gear portion which rotates in association with the rotation of the capstan shaft. The above components of the magnetic recording/reproduction apparatus are situated in such a manner that when the running of a magnetic tape is to be shifted from a first direction to a second direction, the rotation of the capstan shaft, in the first direction stops, the pinch roller moves away from the capstan shaft, the capstan shaft is rotated in the second direction by a predetermined amount so that the idler swings to the first reel base, the capstan shaft stops again, the pinch roller presses the magnetic tape against the capstan shaft, and the capstan shaft is rotated again in the second direction and the gear portion to be coupled with the first reel base, the gear portion rotating the first reel base in a direction in which the magnetic tape is wound onto the first reel.
