A cooling device is provided for a light source in a copying machine, wherein the generation of air seemingly waving due to heat is prevented by effectively cooling a lamp body for lighting an original effectively in order to obviate the deterioration of an optical image. Light pervious heat-shield members are disposed at suitable intervals in an irradiation opening of the lamp body accommodating light source bulb and a reflector therewithin so as to enable blowing of ambient air past and between these members. At least the member positioned at the side of the light source bulb is composed of a heat-ray absorption glass. Air flow is guided through the chamber accommodating the light source bulb so that it may perform a forced air cooling of the inside of the lamp body in order to prevent the generation of the air waving due to heat from the lamp.

Cooling device for a light source in a copying machine

A process camera with an automatic copy-feeder to set a copy at the specific position of a vacuum copy holder, an automatic copy feeder to load or remove the copy, an automatic exposure having mechanism to set exposing conditions, an automatic film processor. The copy feeder is automatically controlled to load and remove copies one by one relating to the condition of the copy holder at the removing position, at the loading position or at the exposing position. On the other hand, the film feeder and the exposure are automatically controlled to perforate, expose and convey a roll film. Further, the exposed film is cut and conveyed into the film processor. Each of these operations are respectively controlled to be synthetically consistent to each other.

Automatic process camera

In a reproduction camera having a slant body and anteroinferior platforms, apparatus for setting or replacing a copy comprises a carrier which is anteroinferior and capable of moving along the slant body, where the optical axis is always vertical thereto, a copy holder which is mounted on the carrier to swing back and forth around a fulcrum, and a plate for holding down evenly a copy mounted on the copy holder by a hinge, by which the plate can be opened or closed. The fulcrum is positioned so that the total centroid of the combination of the holder, the plate and the hinge exists in the rear of the fulcrum when the plate is opened and exist in the fore of the fulcrum when the plate is closed.
