Abstract: An electrostatic copying apparatus comprising a rotating endless photosensitive material (12), an image-forming means (26) for forming an image on the photosensitive material, a conveying means (46) for conveying through a predetermined passage (56) a copying sheet to which the image formed on the photosensitive material (12) is to be transferred, and a cleaning means (18) for cleaning the photosensitive material after image transfer. In the performance of one copying cycle, the image formation is completed before the photosensitive material has rotated through one turn from the starting of image formation, but the photosensitive material (12) is further kept in rotation for cleaning. When a plurality of copying cycles are performed successively, the starting point of image formation in the next copying cycle is selectively set on the basis of the length in the conveying direction of the copying sheet conveyed through the passage (56) during the previous copying cycle.

Abstract: A copying machine comprising an original detecting member upstream of an original-exposing section and a sensitive paper detecting member upstream of a sensitive paper-exposiing section in order to cause both an original and sensitive paper to reach the exposing sections synchronously. The machine also includes a mechanism whereby either the original or the sensitive paper which reaches the detecting member earlier is stopped there temporarily, and when the other late-coming original or sensitive paper has reached the detecting member, the advance of the earlier-reaching original or sensitive paper is resumed.

Abstract: A cleaning device 9 for use in an electrostatic copying machines which removes any residual toner with a blade 23 from a photosensitive body 7 after a toner image has been transferred therefrom to a sheet of copying paper. The cleaning device 9 comprises a support shaft 25 supporting a blade 23 for slidable contact with the photosensitive body 7 and having an horizontal axis extending perpendicularly to a direction of travel of the photosensitive body 7, the support shaft 25 being angularly movable about the axis and axially movable, a rotational shaft 38 rotatable about an axis parallel to the support shaft 25, first means 34, 35 for converting rotational movement of the rotational shaft 38 into reciprocal movement along the axis of the support shaft 25, second means 40, 54 for converting rotational movement of the rotational shaft 38 into reciprocal angular movement of the support shaft 25, and third means 43, 58 for releasing interconnection between the rotational shaft 38 and the first and second means 34, 35, 40, 54.

Abstract: A copying machine of the diazo type comprises a light exposure zone for exposing to light a diazo type photosensitive sheet superposed with an original, a development zone for developing the light exposed photosensitive sheet and a delivery mechanism for feeding the original and diazo type photosensitive sheet to the light exposure zone and forwarding the light exposed photosensitive sheet to the development zone. The light exposure zone includes a transparent cylinder capable of rotating while having a superposed assembly of the original and photosensitive sheet closely contacting the outer surface thereof and a heat-generating light source mounted in the interior of the transparent cylinder. The transparent cylinder has a fan for feeding cold air into the transparent cylinder from one end thereof and cooling the outer surface of the transparent cylinder substantially uniformly along the entire length thereof and a temperature-detecting mechanism thermoconductively contacting the outer surface of the transparent cylinder to detect the temperature of the outer surface. A temperature-controlling mechanism is provided to control the air feed rate of the fan in response to signals from the temperature detecting mechanism, to control the temperature of the outer surface of the transparent cylinder within a predetermined temperature range.

Abstract: A compact photocopier is obtained by having the path lengths of the original and the copy as short as possible for each case, and not equal. The copy sheet and original are inserted into separated slots and are gripped by separate transport rollers which drive at synchronised speeds. Sensors downstream of the rollers monitor the leading edges of the copy and original and the respective rollers are arrested until both sheets are in the same corresponding positions, after which they are scanned and exposed at synchronous speeds. The original then leaves the machine while the copy passes through the remaining processes.

Abstract: A mass of residual toner which is charged is blocked by a blade member 17 held in slidable engagement with a photosensitive member 2 against movement therewith toward a development roller 14 when an image is being formed on the photosensitive member 2. When no image is being formed thereon, the blade member 17 is lifted off the photosensitive member 2 to allow the mass of residual toner to move therewith toward the development roller 14. During this time, a bias potential having the same polarity of the toner is applied to members of an electrostatic or electrophotographic copying machine, located between the blade member 17 and the development roller 14 for repelling the mass of toner toward the photosensitive member 2 against being scattered off the latter and hance smearing surrounding parts.

Abstract: A paper feed device for a copying machine, in which paper jamming at the copying paper cutting mechanism is effectively prevented is provided. This paper feed device for a copying machine comprises a feed reel for supporting a copying paper wound thereon in a roll-like form, a paper feed roller intermittently driven and rotated to take out the copying paper from the feed reel, an introduction roller disposed on the introduction side of a transfer passage for delivering the copying paper to copying treatment zones in the copying machine, and a copying paper-cutting mechanism disposed between the paper feed roller and the introduction roller to cut the copying paper taken out of the feed reel into a prescribed length. The paper feed device further comprises a paper jamming-preventing mechanism for stopping the front end of the copying paper, which is present at the cutting position when the operation of the paper-cutting mechanism is completed, at a position slightly retreated from the cutting position and making the front end of the copying paper stand by for the next copying operation at this retreated position.
