Abstract: An automatic original feeding device includes an original paper feed tray that loads an original to read the image, the original paper feed tray being supported on an upper face of a platen glass for an image reader that reads an image of the original passing through an original reading position set along a straight line on the upper face of the platen glass disposed at an upper end; an original paper output tray, original feeding members feeding sequentially the original laid on the original paper feed tray to the original reading position and the original paper output tray and a strip sheet attaching part attaching detachably a strip colored sheet, the strip sheet attaching part provided in a back platen member disposed in a portion opposed to the original reading position under the condition that the sheet attaching part is supported on the upper face of the platen glass.

Abstract: The present invention provides an image reading apparatus including: a document feeding unit that feeds a document along a feeding path; a read-out sensor that reads out an image from the document fed by the document feeding unit without stopping the feed; a control unit that causes the read-out sensor to stay on standby in a predetermined retracted position at a distance from the feeding path when it is not necessary to read out the image of the document, and causes the read-out sensor, when it is necessary to read out the image of the document, to move to a predetermined document reading position and to read out the image from the fed document; and an output unit that outputs the image data read out by the read-out sensor.

Abstract: An image forming apparatus is capable of detecting the presence or absence of sheets before a bottom plate moves up during a so-called initial operation, such as an operation for setting a sheet loading tray in the apparatus, and preventing the bottom plate from running wildly during, for example, an upward movement thereof.
