摘要:
Apparatus for forming an image on a record medium comprising transport means (10,13) for causing a record medium to be transported along a transport path within the apparatus so as to be discharged therefrom; a rotatable image-receiving member (1) for receiving the said image; a transfer device (5) adjacent the transport path for transferring the image from the image-receiving member (1) to the record medium; and a fixing device (11) adjacent the transport path for fixing the image on the record medium characterised in that the apparatus is provided with a door (23) which, when open, provides access to the transport path within the apparatus and which is pivoted around an axis parallel to that of the image-receiving member (1), the arrangement being such that, when the apparatus is in use with the door closed, the portion of the transport path between the transfer device (5) and the fixing device (11) is inclined at an angle from the vertical of at least 10⁰ and substantially less than 90⁰ and that the apparatus is arranged such that the record medium is discharged therefrom with the said image face down.

The arrangement is such that any jam can readily be cleared even by an inexperienced user in a natural posture without any fear of his hands being stained and with no risk to the apparatus being damaged. It is also such that the user can reliably exchange a cartridge, preferably employed in the apparatus, in a natural posture; this being achieved by performing almost the same operation as a jam removing operation from the front side of the apparatus from which paper is preferably discharged in normal use.

A preferred embodiment of this continuous-form electrophotographic printer as illustrated in the drawings having an image transfer device 38 positioned at the image transfer station for placing images on individual sheets 14 of a continuous-form 12. Downstream, a distance A, is a fixing device at an image fixing station 32 for fixing the image onto the individual sheet 14. The printer 10 includes a control means 76 for moving the continuous sheet forward when a stop signal is received to position a leading edge of a sheet at the image fixing station 32. When a restart signal is received, the control system initiates the continuous-form feeding means 38 to move the continuous-form 12 forward until a leading edge of a succeeding sheet is positioned at the image transfer station.

摘要:
Apparatus for forming an image on a record medium comprising a photosensitive member (1); a charging device (2) for charging a portion of the photosensitive member (1); an optical signal generator (3) for irradiating the photosensitive member (1) with a light pattern so as to produce a latent image thereon; a developing device (4) for applying toner to the latent image so as to develop the latter; a transfer device (5) for transferring the toner-developed image from the photosensitive member (1) to the record medium; and a fixing device (11) for fixing the so-transferred image on the second medium characterised in that the apparatus is provided with a detachable cartridge (22) which carries at least the photosensitive member (1) and the transfer device (5), the transfer device (5) being disposed above the bottom portion of the photosensitive member (1).
摘要:
The invention provides a suction-type sheet-carrying mechanism, applied to a high-speed image-forming apparatus, by which a sheet is separated from an electrophotosensitive drum (101) by air suction brought about by mechanically combining fixed air suction holes (37a, 40a) of a hollow shaft (37) and rotated air suction holes of belt pulleys (38), the sheet is stuck onto rotating endless belts (32) and carried along a curved route by air suction brought about by combining moving air holes (41 a) of the moving endless belts, high-speed air flow running through ditches (47a) provided on a belt guide board (47) placed under the endless belts, and the sheet is carried through a fixing unit (107) in which it is exposed to high temperatures by rotating air suction metal rollers (209) arranged perpendicular to the sheet-carrying direction, combining fixed air suction holes (11a) in a hollow shaft (11) and rotating air suction holes (10a) in ring-shaped ridges (10c) of a hollow cylinder (10) rotated around the hollow shaft of each air suction metal roller.
