摘要:
When a photographic film is to be printed, it is necessary to remove such defocused photographic images which are caused by improper focusing. In this invention, transmittivity or transmission density of an image recorded on photographic film is measured consecutively by scanning it with two photometric systems having different measuring areas, and a defocused photographic image is detected from the relation between the measured distribution of the difference between two measured values in the transmittivity and the contrast values which is obtained by totalling local contrasts measured all over the photographic film.

A conveying body that can attract and peel-off a recording medium by a simple mechanism, and an image forming device using the conveying body are provided. One end portions of through-holes of a drum are blocked by a blocking member, and a suction member and a blowing-out member are provided at other end portions of the through-holes. Due to a suction pump being operated and suction force being generated within the through-holes via a suction port of the suction member, the suction force passes through the through-holes and acts on long grooves of an outer peripheral surface of the drum, and a sheet can be attracted reliably to the outer peripheral surface of the drum. Further, because air is blown-out from the blowing-out member by operation of the suction pump, a leading end portion of a sheet can be reliably peeled-off from the outer peripheral surface of the drum.

摘要:
An image forming device in which, at a loading position, recording media are loaded onto stage members, and images are formed on the recording media while the stage members pass through an image forming section, and thereafter, the recording media are removed from the stage members at a removal position. In the image forming device, two traveling bodies, which move along predetermined paths between the loading position and the removal position, are provided in parallel. The stage members are mounted to the traveling bodies respectively so as to jut out from the traveling bodies. Each traveling body has a mechanism which moves the traveling body in vertical directions so that the stage members do not interfere with one another when they pass by one another. Image formation is carried out alternately on the recording media loaded on the respective stage members, and image forming processing can be carried out efficiently.
