摘要:
A camera incorporates a photo film support plate, which supports a back of photo film. The photo film has a magnetic recording area. An opening is formed in the photo film support plate. A magnetic head projects forwards from inside the opening, for recording information to and/or reading information from the magnetic recording area. A head base plate is mounted on a rear face of the photo film support plate to cover the opening, for supporting the magnetic head. Adhesive agent is applied to the periphery of the head base plate, and hardened for securing the head base plate to the photo film support plate. A pair of recesses are formed in a rear face of the head base plate in a vicinity of the periphery. The adhesive agent is disposed to extend from a front face of the head base plate to a surface of the recesses, which enlarge a contact area between the adhesive agent and the head base plate.

Temperature is detected by a temperature sensor disposed near a recording head. When the detection result is a temperature that is higher than room temperature, an appropriate movement amount of the recording head is calculated from a relation between response speed of the temperature sensor and a LED light amount, and a moving speed of the recording head is controlled. When the result of the detection by the temperature sensor is a temperature that is lower than room temperature, an appropriate exposure amount is calculated from the relation between the response speed of the temperature sensor and the LED light amount, and the amount of light emitted by LEDs is controlled.

A reflection prevention film coats a backside of a stage glass by a vacuum evaporation and coating, etc. A light from a metal halide lamp is not reflected on the back of the stage glass by the reflection preventing film, and is transmitted through the stage glass and is reflected on a surface of the stage glass and a transparent manuscript. The light reflected on the surface of the stage glass and the transparent manuscript enters a projection lens unit and appears as a spot light on a screen, but because the light is not reflected on the backside of the stage glass, so that the amount of the light, which causes the spot light, can be reduced. As a result, the spot light on the screen is inconspicuous.

An endoscope has a section of an elongated tube for entry in a body cavity. An end shell is disposed at a distal end of the elongated tube. An imaging window area is formed in the end shell. A lens barrel is secured to the end shell, and aligned with the imaging window area. An imaging device photoelectrically detects object light from the lens barrel. A circuit board has the imaging device mounted thereon. A signal cable has a cover material, and plural filaments covered by the cover material, and connected to the circuit board. A cable retaining device partially retains the cover material fixedly. A tip portion is formed at a distal end of the cable retaining device. A coupling device keeps the tip portion laterally movable on the end shell, to prevent stress in the cable retaining device from exertion to the end shell.

An end portion of a signal cable is fixed to the inside of a rear end of a connecting member by a first adhesive material. A flange of a lens barrel is engaged to a pair of claws of the connecting member. The signal cable is connected to the lens barrel through the connecting member so that the signal cable is not peeled from a flexible substrate. The connecting member does not cover a CCD and a first tip of the flexible substrate. The diameter of a distal portion of an electronic endoscope can be made smaller by eliminating the thickness of the connecting member and the thickness of the adhesive material filled between the connecting member and the CCD.

In order to reduce the frame rate, when all photodiodes contributing to output of a video signal in a CMOS image sensor must be simultaneously exposed (at the timing of strobe flashing Δts), as in a case where strobe is flashed, readout pixels composing the CMOS type image sensor are thinned such that the number of photodiodes contributing to the video signal outputted from the CMOS type image sensor is reduced. A time period Δtp2 required for processing (of the video signal caused by a row of photodiodes) in an analog processing circuit connected to the succeeding stage of the CMOS type image sensor is shortened, thereby reducing the frame rate.

A projector of a reflection type has a transparent stage plate on which a transparent original sheet is set. A lamp illuminates the original sheet through the stage plate. A Fresnel mirror is laid on an upside of the original sheet, and reflects light from the original sheet in a convergent manner. The light from the Fresnel mirror is reflected away from the stage plate. The light is again reflected, and incident upon a projecting lens, which projects an image of the original sheet to a screen. A housing contains the Fresnel mirror in movable fashion. An inserting slot is formed in the housing, into which the original sheet is inserted during supply of the original sheet. Photo sensors operate to detect a front edge of the original sheet inserted through the inserting slot. It is also detected that the original sheet is set on the stage plate. An ejector switch is operated for ejection of the original sheet. A solenoid shifts the Fresnel mirror up away from a set position in response to a signal from the photo sensors or the ejector switch. The Fresnel mirror is shifted down to the set position in response to a sheet setting signal, to lie on the original sheet. A sheet feeder roller moves the original sheet from the inserting slot to the stage plate during the supply, and moves the original sheet out of the housing during the ejection of the original sheet.
