摘要:
A heat sink is attached to a subject-side end portion of a barrel body of a lens barrel. The heat sink is provided with a large number of radiation fins formed in whorl. A heat pipe is disposed between the heat sink and a mount-side end portion of the barrel body. A CCD is fixed to the mount-side end portion of the barrel body. Heat of the CCD is transferred to the heat pipe via the mount-side end portion. Successively, the heat is efficiently transferred to the heat sink by the heat pipe. The heat having been transferred to the heat sink is efficiently radiated into the air by the whorl-like radiation fins regardless of conditions of the lens barrel.

In a printer incorporating thereinto a fuel cell for generating electricity upon receipt of supply of liquid fuel, an ink cartridge storing ink is mounted on a carriage, and the ink stored in the ink cartridge is ejected to a recording medium so that an image is recorded on the recording medium. The ink cartridge stores ink, and has a liquid fuel storage section that stores the liquid fuel, and a water storage section that stores water. The printer has: the fuel cell having a fuel electrode, an air electrode, and a solid-electrolyte film, in which the fuel electrode receives the liquid fuel and water is discharged through the air electrode; a fuel supplying path for supplying the liquid fuel stored in the liquid fuel storage section to the fuel electrode; and a water forwarding path for forwarding the water discharged from the air electrode to the water storage section.

There is disclosed a distance measuring equipment capable of enhancing an accuracy of focusing, and a camera capable of enhancing an accuracy of focusing and/or reducing a cost with a small scale of circuit. In the event that a photography is performed at the relatively short distance, first and second switches of an SPD are switched by an MPU to turn off and turn on, respectively. An AF-dedicated photo detector circuit determines a distance up to a subject in accordance with both the photo-currents I1 and I2 obtained through two signal electrodes. On the other hand, in case of the relatively long distance, the MPU switches the first and second switches of the SPD are switched to turn off and turn on, respectively, so that another AF-dedicated photo detector circuit determines a distance up to the subject in accordance with photo-current I3 obtained from one of the signal electrodes. In this manner, in the event that a photography is performed at the relatively long distance, there is performed a processing of determining a distance up to the subject in accordance with a total quantity of light.
摘要:
A variable power reflectory type overhead projector for forming a projected luminous beam by lighting a reflecting mirror from the projecting lens side. A transparent film-to-be-projected support is provided between a regular position of the film to be projected and the projecting lens, and an auxiliary lens is included for focusing the projecting lens on the support.

A video camera includes a casing having a generally rectangular parallelepiped shape, a first imaging optical system for shooting a still image and a second imaging optical system for shooting a video picture. The first and second imaging optical systems are disposed in a front surface of the casing so as to be directed to an object scene. A still camera unit is also disposed in the casing in the proximity of the first imaging optical system for shooting the object scene to record a still picture thereof on a film. A video circuit is provided in the casing on the rear side of the second imaging optical system for shooting the object scene to form a video signal representing a movie picture thereof, and a video tape recording section is also provided in the casing on the rear side of the first imaging optical system for recording the video signal on a video tape. The casing includes a first opening to load a film in said still camera unit and a second opening to install a video tape cassette in the video tape recording section. The first and second openings are disposed in an upper surface of the casing.
摘要:
An overhead projector having a stationary main body including a Fresnel plate, a projection unit, and a swingable member for supporting the projection unit and swingably secured to the main body. The overhead projector comprises one way clutch means through which the swingable member is secured to the main body and which is adapted to limit the swinging motion of the swingable member towards the main body.
摘要:
A water-resistant camera has a lens barrel movable toward and away from a fluid-tight camera body for selecting the position of the lens barrel between wide-angle and telephoto positions. The camera has or can be combined with an automatic air-pressure adjusting mechanism for automatically keeping the air pressure in the inner space of the camera at a substantially constant level irrespective of the position of the lens barrel between the wide-angle position and the telephoto position. Therefore, the lens barrel can smoothly be moved with respect to the camera body upon switching between the wide-angle and telephoto positions.

A shooting system of the present invention comprises a silver-salt camera unit shooting on a silver-salt photosensitized material, an electronic image pickup unit which is detachably combined with the silver-salt camera unit and in which a solid image pickup element is embedded, and a control unit which is combined with the electronic image pickup unit instead of the silver-salt camera unit.
摘要:
A projector comprises: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame. The projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame.
