摘要： An original document size estimating device includes a first optical sensor and a second optical sensor operable to detect an original document placed on a specified position. The first optical sensor is positioned before the second optical sensor with respect to a forward direction. The first and second optical sensors are moved in both the forward direction and a backward direction opposite to the forward direction by a driver. The driver is controlled in such a manner as to forcibly move the first and second optical sensors in the forward direction further a predetermined additional distance when the first optical sensor generates absence signal and the second optical sensor generates presence signal, and return them after both generating absence signal to measure a length of the original document for size estimation.

摘要： An image forming apparatus comprises a document feeder for feeding a plurality of documents one by one, a copy paper feeder for feeding a copy paper sheet having a front surface and a rear surface onto which document images are transferable, an image transferring assembly for transferring an image of the fed document onto a copy paper sheet, an operable unit for discharging the copy paper sheet or temporarily retaining the copy paper sheet therein to refeed the sheet to the image transferring assembly when a next document is fed, a mode setting key for selectively setting in advance either of a first mode in which the copy paper sheet onto which the last document image is transferred is forcibly discharged or a second mode in which the copy paper sheet onto which the last document image is transferred is temporarily retained in the operable unit, and a CPU. The CPU determines that an image of a last document of the plurality of documents has been transferred onto one of the two surfaces of the copy paper sheet and determines in accordance with the result of the above determination that the last document image is transferred onto a front surface of the copy paper sheet. Further, based on the determination as to whether the last document image is transferred onto the front surface of the copy paper sheet and the mode set by the mode setting key, the CPU controls the operable unit so as to execute one of the operations of discharging the copy paper sheet onto the rear surface of which the image of the document is transferred, discharging the copy paper onto the front surface of which the last document image is transferred in the case where the first mode is selected, and retaining therein the copy paper onto the front surface of which the last document image is transferred in the case where the second mode is selected.
