The present invention provides an image scanning apparatus 100 including a stand block 1 having a support arm 3, a scan type illumination device 5 for applying a slit-shaped light beam 8 onto a surface of a manuscript 2, and a manuscript image scanning device 4 mounted on the support arm 3 for receiving the slit-shaped light beam 8 reflected from the surface of the manuscript 2 and having a manuscript image. The scan type illumination device 5 applies the slit-shaped light beam 8 in a direction 11 vertical to the longitudinal direction of the slit-shaped light beam 8. The manuscript image scanning device includes a manuscript image input block 13 and a light detecting device 14 for receiving the reflected light 8′ output from the manuscript image input block 13. The manuscript image input block 13, in synchronization with the scan operation of the scan type illumination device 5, introduces the reflected light 8′ into a predetermined position of the light detecting device 14.

In an image pick-up apparatus, the image on a visual field over an original copy is focused on an one-dimensional image pick-up device by a lens through a mirror. A prism for taking in the ambient light is disposed at the end portion of the one-dimensional image pick-up device. A sample-hold circuit samples and holds an ambient light signal portion of the image signal Vin and outputs a sample-hold signal Vref. A division circuit performs the operation of division Vin/Vref, using the sample-hold signal Vref. As a result, the image signal Vin will be normalized by the ambient light signal Vref for each scan line (line by line). An amplification circuit amplifies the output Vin/Vref of the division circuit so that the ambient light signal level may become VO and outputs it to an A/D conversion circuit. The image signal quantified by the A/D-conversion circuit is output to an external equipment by an external I/F circuit.

The present invention enables to scan in a sub scan direction an image on a scan medium placed on a flat plane using a simple configuration of a one-dimensional image sensor at a fixed position in combination with a reflecting mirror. A drive source having a constant rpm is used to rotate the reflecting mirror at an angular velocity changing in a non-linear way. The rotation of the drive source is transmitted to a drive mechanism linked to a four-node link mechanism to rotate the reflecting mirror at an angular velocity changing in a non-linear way, so that the scan position on the scan medium is shifted in the sub scan direction at a constant linear velocity.

An image scanning apparatus enables to scan an image in a sub scan direction on a scan medium placed on a plane with a one-dimensional image sensor at a fixed position via a reflecting mirror rotatable around a fixed axis without causing a scan defect due to a change in the optical path length. An image light generated from an image on a scan medium is deflected by a reflecting mirror so as to from an image at a position of an image sensor via an image formation optical system. This image sensor reads a scan image as a one-dimensional main scan line and the reflecting mirror is rotated so as to move a scan position in a sub scan direction. The rotation of this reflecting mirror is interlocked with displacement of the image formation optical system in an optical axis direction, thus enabling to prevent an image formation defect due to a change in the optical path length.

A porous electrode sheet (1) includes a resin film (2) being transparent and having insulating properties, and a transparent electrode (3) placed on one face (2a) of the resin film (2). The resin film (2) is provided with a plurality of through holes (21) extending linearly from the one face (2a) to the other face (2b). The transparent electrode (3) has openings (31) at positions corresponding respectively to the through holes (21). The through holes (21) of the resin film (2) and the openings (31) of the transparent electrode (3) communicate with each other, and thereby form passages (10) penetrating the porous electrode sheet (1) in the thickness direction.

A post-processing method involves using a standby tray to receive a paper sheet to be supplied from a digital copier, a processing tray to receive a paper sheet dropped from a standby tray, a feed member which guides the rear end of a paper sheet received in a standby tray in the feeding direction to a processing tray, and scrapes and sends the rear end of a paper sheet dropped onto a processing tray to a stopper, a press member which clamps the rear end of a paper sheet received in a standby tray by cooperating with two feed members, and a stapler to staple the aligned rear ends of paper sheets. When a first paper sheet is supplied to the standby tray, the press member presses the rear end of the first paper sheet, to receive a second paper.
