摘要： A semiconductor radiation sensor arrangement for an automatic X-ray exposure control apparatus disposed in front of an X-ray film to be exposed to X-rays. A semiconductor radiation sensor is set in a mount. The mount is bored with a tapering penetrating hole and securely engaged with a hole penetrating a substrate. The peripheral walls of the mount and that of the penetrating hole of the substrate are tapered in cross section in the similar form. The semiconductor radiation sensor is fixed in the penetrating hole of the mount and has a sufficiently small thickness to cause X-rays to be attenuated to a less extent than 800 microns of aluminum equivalent thickness. Leads are formed of an aluminum layer with a smaller thickness than 80 microns and connected to the electrodes of the semiconductor radiation sensor. At least one scattered X-ray eliminating grid is disposed in parallel with the substrate and the semiconductor radiation sensor.

摘要： A camera having a barrier according to the present invention includes a barrier unit in a space between a front main body and a front metal cover serving as an exterior member. Rotation of a barrier driving motor is transmitted to a rotary shaft member passing through the front main body, thereby allowing opening/closing actions of the lens barrier between a protection position for a photographing lens and a lens-barrier retracted position. The front main body is sealed waterproof by an O-ring provided to the outer circumferential surface of the rotary shaft member. With the lens barrel of the camera, rotation of a rotary moving frame is effectively transmitted to a cam frame through a cam follower fit to a linear-action groove, using a circumferential groove and the linear-action groove of a bayonet mechanism.
