    摘要： In order to allow the surgical operator and his assistant to make stereoscopic viewing of the region of surgery with a same magnification and in coaxial relationship, the surgical microscope comprises: a common objective lens; a pair of variable magnification optical systems disposed on the image side of the objective lens; and a pair of light beam splitting members disposed on the image side of the pair of variable magnification optical systems, respectively, wherein arrangement is provided so that paired observational optical paths are to be directed to extend respectively in a plurality of directions each having a predetermined angle relative to a plane containing the optical axes of the pair of variable magnification optical systems, within a plane crossing these optical axes at right angles, respectively. The pair of light beam splitting members are constituted as an optical path splitting unit, and the barrel section and the optical path splitting unit are removably coupled to each other.

    摘要： A film end detector for use in automatic film winding camera comprises a rotary disc having a light transmitting area and mounted on the drive shaft of a motor which is used to wind up a film automatically. The rotation of the disc is monitored by a combination of a light source and light receiving, photoelectric transducer element which are disposed to monitor the passage of light through the light transmitting area, thus detecting a film end. Logic circuits examine the output of the photoelectric transducer element at predetermined intervals to ascertain the completion or failure of completion of a normal film-winding operation.

    摘要： In a recording medium conveyer, a driver drives a feeding member and a conveying member provided downstream from the feeding member in a recording medium conveyance direction independently. A controller stops driving the feeding member when a first time period elapses after a recording medium reaches the conveying member. When a selector judges that the thickness of the recording medium identifies the recording medium as thin paper, the controller does not drive the feeding member after the controller starts driving the conveying member, and when the selector judges that the recording medium has a thickness greater than a thickness of the recording medium that identifies the recording medium as thin paper, the controller restarts driving the feeding member no later than when the controller starts driving the conveying member.
