摘要:
The present invention relates to an image reading apparatus comprising an original document conveying route, original document conveying mechanism for conveying original documents along the original document conveying route, first reading unit for reading an image on one side of the original document; and second reading unit for reading an image on the other side of the original document. The first reading unit reads an image on one side of the original document while the original document is conveyed in a forward direction at a first speed by the original document conveying mechanism, and then after the original document is conveyed in a reverse direction at a second speed, the second reading unit reads the other side of the original document while the original document is again conveyed in the forward direction. The second speed is faster than the first speed.

A sheet feeding apparatus of the invention comprises a conveying belt which is driven in such a direction as to send sheets, a belt or the like which is driven in the direction opposite to the belt conveying direction so as to apply a predetermined resistance force to the feeding of the sheets, and a frictional member adapted to be come into pressure contact with the conveying belt through the sheets. With the apparatus, the sheets can be certainly separated one by one irrespective of the material and thickness of the sheet.

An original-reading device has a first mode of reading an original mounted on an original-mount while moving a scanning unit for scanning the original, and a second reading mode of reading an original being moved while stopping the scanning unit at a predetermined position. The size of the device can be reduced by making the position where the scanning unit stops in the second reading mode within the moving range of the scanning unit in the first reading mode.

An image forming apparatus includes a sheet mounting unit for accommodating sheets, a moving unit for automatically moving the sheet mounting unit between a feed position within a main body of the image forming apparatus for feeding the sheet and a drawn position wherein the sheet mounting unit is drawn from the main body of the image forming apparatus, wherein the moving unit includes a driving device for generating a driving force to automatically move the sheet mounting unit. Also provided are an image forming unit for forming an image on the sheet, a conveying unit for feeding and conveying a sheet from the sheet mounting unit at the feed position to the image forming unit, a sheet detection unit for detecting a stoppage of the sheet being conveyed by the conveying unit, and a control unit for controlling the moving unit to automatically move the sheet mounting unit from the feed position to the drawn position according to a detection by the sheet detection unit.
摘要:
A two-color copying apparatus has a half reflecting mirror located posterior to an image forming lens in the path of a light beam for splitting a light beam reflected by an original in black and a chromatic color for development of corresponding latent images on respective photoconductive drums and printing on a transfer-printing sheet conveyed by a conveyor belt and successively brought into contact with the outer circumferential surfaces of the drums. The sub-beam of light reflected by the half reflecting mirror and the sub-beam of light transmitted through the half reflecting mirror serve as a chromatic color image forming sub-beam of light and a black image forming sub-beam of light, respectively, which are projected on to quadrants on the outer circumferential surfaces of the two drums located on opposite sides of the drums with respect to imaginary vertical lines extending through the centers of the respective drums which are remote from the positions in which the transfer-printing sheet is brought into contact with the drums.
