Abstract: PURPOSE: To provide the camera unit in which an image pickup object is quickly switched by arranging a reflecting member to switch an object area. CONSTITUTION: This camera unit 11 is made up of a lens unit 11a, an image pickup means such as a CCD arranged to an image forming position of the lens unit 11a, and a mirror 12. The mirror 12 is rocked from its escaping position till its inserted position by a rotary shaft 12a provided to a front side upper part of the camera unit 11. The mirror 12 is driven around the rotary shaft 12a by a driver 15 and its angle is adjusted. When the mirror 12 is located at its inserting position, a light of a sample located on a sample placing board is led to the camera unit 11 via the mirror 12 and its image is formed on a light receiving face of the image pickup means. When the mirror 12 is in the escaping position, the object in front of the lens unit 11a is picked up.

Abstract: PURPOSE: To prevent positional deviation in an optical system in the extended state of a movable lens barrel provided to be extended, and to simplify the supporting structure of the optical system in what is called a retractive type lens barrel which can be extended. CONSTITUTION: A reference surface 13 is formed on the rear end face of the outer flange 11 of a fixed lens barrel 1, and a frame body 26 functioning as an inner flange attached to the rear end of a movable lens barrel main body 8a is formed and a surface which is made reference 27 is formed on the front end face of the frame body 26. When the movable lens barrel 8 is extended to the fixed lens barrel 7, the surface 27 of the movable lens barrel 8 is pressed to the reference surface 13 of the fixed lens barrel 7, so that the optical axis of a movable side optical system 10 is aligned with the optical axis of a fixed side optical system 9 in a photographing feasible state.

Abstract: PURPOSE:To miniaturize a tape cassette by providing an optical path of a finder so as to pass through the window inside of the tape cassette. CONSTITUTION:The window 2 penetrating through the front and rear sides is provided on a dead space part located at the opposite side of a mouse part 56 of the tape cassette 1. In the camera incorporated type magnetic recording/ reproducing device 11, when the cassette 1 is set to the loading position in the loaded state on the loading position under the state loaded on a linear skate chassis 15, a lens system 33a, openings 24,17, window 2 and a lens system 33b are arrayed on an optical axis 34, then a photographer can see an object through the finder 33. By this arrangement, the miniaturization is attained since the optical axis 34 of the finder 33 can be provided at the minimum distance across the cassette 1.

Abstract: PURPOSE:To obtain a thin, downsized rotary magnetic head drum unit in which a high torque is realized and so-called 'judder' of yoke board is suppressed remarkably, without employing a magnet material having a high coercive force in the yoke board or increasing power, by a constitution wherein a motor stator is interposed between the yoke board made of a laminate of a viscoelastic magnet and a yoke board rotating in synchronism with a motor rotor and the magnet of the motor rotor. CONSTITUTION:A motor stator 3 is interposed between a yoke board 2 made of a laminate of a viscoelastic magnet 10 and a yoke board 2 rotating in synchronism with a motor rotor 4 and the magnet of the motor rotor 4.

Abstract: PURPOSE:To provide a solid-state image sensor which can be fixed to an optical apparatus even without using a sheet metal fixing. CONSTITUTION:A solid state image sensor 1 comprises at least two positioning plates 20 horizontally protruding from sidewalls 12, 12' of a package and having positioning holes 22. Thus, an optical axis of an optical apparatus can be easily brought into coincidence with a center of a solid-state image sensor chip and yet a light receiving surface of the chip can be held perpendicularly to the optical axis.

Abstract: PURPOSE:To prevent a tape from being run onto a rotary head drum by shutting a gap between a cover body and the circumference surface of the rotary head drum with a tape shutter, which is turned in the vertical direction when the cover body of a tape cassette is opened. CONSTITUTION:The tip of a tape shutter 27 contacts a circumference surface 4a of a rotary head drum 4 and completely shuts a gap A between a cover body 8 and the circumference surface 4a of the rotary head drum 4 when the cover body 8 is opened. Accordingly, for example, even when looseness is generated in a tape 9 between front opening parts 7a and 7b of a tape cassette 7 to be opened by the opening of the cover body 8 and this tape 9 tends to jump out on the rotary head drum 4 simultaneously with the slight opening of the cover body 8, the tape shutter 27 goes to be a wall and the tape 9 is not run onto the rotary head drum 4. Then, the tape 9 is securely guided between the circumference surface 4a of the rotary head drum 4 and the cassette 7 by the tape shutter 27. Thus, the tape 9 can be prevented from being loaded on the rotary head drum 4.

Abstract: PURPOSE:To simplify a structure and to miniaturize a device by fitting a rotary head drum on one side of a movable chassis, supporting the other end side pivotally with a fixed chassis by a shaft, turning it around this shaft and displacing the rotary head drum toward the side of a cassette. CONSTITUTION:The rotary head drum 6 is supported by a cylindrical drum receiver part 9 in its inside formed on one side of the movable chassis 7, whereas an arm 10 is provided on the other side, and a cylindrical bearing part erected in the middle part of the arm is inserted by a shaft 13, so that this side is turnably fitted to the fixed chassis. When the movable chassis 7 is turned clockwise, the rotary head drum 6 is moved into a space 3a for a drum receiver of the cassette 3, and at the same time, the movable chassis 7 up to the rotary head drum 6 are positioned in height at the three spots of 1st-3rd boss parts 15, 18 and 20. On the other hand, the movable chassis 7 is positioned in its turning direction by a shaft 21 provided in the vicinity of one side part 17a of a positing part 17 and the boss part 18. By this method, simplification of a structure, miniaturization of a mechanism and lightening of a device can thus be contrived.
