An original pressing device for use in a reading apparatus. There is a hinge together with a pressing unit supported pivotably by the hinge and pivoting between a closing position where an original on a platen is pressed and an opening position where the original is released. A coil spring is compressed with the closing operation of the pressing unit and is released from the compression along with the opening operation of the pressing unit, and a fluid damper is arranged within a hollow portion of the coil spring to provide a resistance force when the pressing unit performs the closing operation.

The present invention provides an automatic original supplying apparatus which includes an original stacking plate on which originals can be rested, and an original conveyor for separating and supplying the original, one by one, and for conveying the separated original to a reading position. It operates in a flow reading mode in which a reader is fixed and the original is shifted with respect to the reader, a fix reading scan mode in which the original is fixed at the reading position and the reader is shifted with respect to the fixed original, and a count mode in which the number of originals is counted. The original conveying speed in the fix reading scan mode is faster than the original conveying speed in the flow reading mode, and, in the count mode, the original is conveyed under the flow reading mode.

A reading apparatus includes an image reader for reading a sheet original positioned at a reading position and an automatic original conveyor for supplying the sheet original onto the reading position, wherein the sheet original can be read through an image flow reading mode while the sheet original is being conveyed by the automatic original conveyor by fixing the image reader at any position. The apparatus also has a convey path for directing the sheet original to the reading position, and a controller for initiating conveyance of the sheet original waiting at a predetermined position in the convey path in response to a flow reading mode start signal during the image flow reading mode and for initiating the image flow reading mode by outputting an image tip signal when a tip end of the sheet original reaches a flow reading image tip position.

A sheet feeding apparatus has a separation device including a rotational feeding member rotatable in the direction of sheet feeding and a counter-rotational member rotatable in the direction counter to the sheet feeding direction, and an elastic member disposed in resilient contact with the rotational feeding member in a region near a nip formed between the rotational feeding member and the counter-rotational member, so as to perform sheet separation in cooperation with the rotational feeding member. The leading ends of the sheets delivered from a sheet tray by a delivery roller are staggered in the nip between the rotational feeding member and the elastic member, and the staggered sheets are separated one-by-one in the nip between the rotational feeding member and the counter-rotational member.

A sheet supplying apparatus has a sheet stacking plate on which sheets are stacked, a drive unit for vibrating the sheet stacking plate upwardly and downwardly, and a sheet supply mechanism for supplying the sheet from the sheet stacking plate. A sheet supplying condition detecting device detects poor supply of a sheet bundle, and the drive unit is operated on the basis of a detection signal of the sheet supplying condition detecting device so that clogging of the sheets, poor sheet separation and poor sheet supply can be prevented.

The present invention provides an original conveying apparatus in which originals stacked on an original tray are separated one by one by a separation unit to be conveyed to a reading portion for reading an image, and then the read original is discharged. An original travel direction reverse path is disposed between the separation unit and the reading portion, a face turn-over path is provided for turning over the original discharged from the reading portion and for directing it to the reading portion again, and there is a control unit for continuously effecting, for the respective original, a first image reading mode in which the travel direction of the original is reversed in the original travel direction reverse path without turning over the front and rear faces of the original before the original is conveyed to the reading portion and then the image is read, and a second image reading mode in which the original is turned over in the original travel direction reverse path after the first image of the original was read at the reading portion.

The present invention provides a sheet original conveying apparatus having an original reverse apparatus and in which originals stacked on a tray are separated one by one by a separation means and a separated original is supplied to a reading portion for reading an image. It comprises a first convey path provided at a downstream side of the separation means in a supplying direction to direct the supplied original to the reading portion, a second convey path branched from the first convey path to direct the supplied original to the reading portion after a travelling direction of the original is reversed in a travel reverse portion, and a switching means disposed at a branched area between the first and second convey paths to switch the first and second convey paths from one to the other.
