Abstract:
A toner image heating device for heating a recording material holding a toner image includes: a first heating roller having a plurality of heaters which are different in heat generating region from one another; and a second heating roller having a plurality of heaters which are different in heat generating region from one another. A heat generating region dividing position between said heaters adjacent to each other in said second heating roller is shifted from a heat generating region dividing position between said heaters adjacent to each other in said first heating roller.
Abstract:
An electrophotographic apparatus is provided in which toner stick hardly occurs by improving the cooling effect on the strip of paper sheets after they are heat-fixed. This electrophotographic apparatus includes a fixing unit for heating toner transferred on a continuous strip of paper sheets and fixing the toner, and a folding unit for supplying a folding force to the continuous strip of paper sheets. A conveyer unit is arranged in the back stage of the electrophotographic apparatus for transferring the continuous strip of paper sheets, received from folding unit, in the horizontal direction.
Abstract:
Preheating temperature of a preheating plate provided on the front side of a fixing unit can be changed using a temperature controller. In a case where a printing system to print images on both sides of a print member is constructed by arranging two electrophotographic printing apparatuses in dependent relationship, the preheating temperature of the preheating plate in the electrophotographic printing apparatus in the second stage is changed to a low temperature to prevent the toner image fixed in the electrophotographic printing apparatus in the first stage from softening.
Abstract:
A simple optical recorder which permits alignment of scanning positions of a plurality of laser beams with high accuracy and effects optical recording using the laser beams. The optical recorder is provided with a photosensitive drum which is scanned by a plurality of laser beams formed in rows at an inclined angle with respect to the direction of scan, a single photosensor for sensing each of the sweep positions of the laser beams, and a controller for controlling the scanning positions of the laser beams on the basis of a sensing result of the sensor. The controller is made up of an optical sensing signal separation circuit, synchronous clock generation circuits, FIFO memory circuit elements, and OR circuits.
Abstract:
An optical fiber composite insulator which includes an insulator body having a through-hole formed in its axis portion and at least one optical fiber extending through the through-hole and sealed in the through-hole by an inorganic vitreous sealing material at both end portions of the through-hole. The sealing material has substantially the same thermal expansion coefficient as that of the insulator body, has high resistances against breakage in the power frequency voltage test and in the lightning impulse voltage test, against crack formation in the cooling and heating test, heat proof test and heat cycle test, and against the light-transmission loss.
Abstract:
In order to adapt a thermal head for a thermal printer to a raised speed, the thickness .delta.(.mu.m) of a heat accumulating layer in the head is set at: ##EQU1## where k: temperature conductivity of the heat accumulating layer,t.sub.p : heating duration of the thermal head, andt.sub.O : printing cycle of the thermal head.
Abstract:
A printing head is disclosed in which each attraction member is driven by a magnetic attraction and an impact printing operation is carried out by a strain energy caused by a displacement of a spring member provided on the attraction member. The fulcrum of rotation of the attraction member is defined between the attraction member and a magnetic polar face of a yoke constituting a magnetic circuit together with the attraction member. Means for adjusting the resilient force of the spring member is engaged with a free end of the spring member.
