摘要:
A sorter incorporating a stapler is an apparatus for sorting and stapling sheets discharged from an image forming apparatus. This sorter includes a plurality of vertically movable bins for storing the supplied sheets, a bin drive unit for conveying the bins, a stapler for stapling the sheets stored in the bins, a pair of lateral guides, and a lateral guide drive unit for moving the lateral guides. The lateral guides are movable in the width direction of the sheets in the bins and abut on both sides of stacks of the sheets to arrange them into widthwise adjustment, and then to move them into the stapling position of the stapler.

It is an object of the present invention to provide an information classification device capable of classifying retrieved pieces of information into appropriate groups even if these pieces of information are the same kind of information. The information classification device according to the present invention includes spatial arrangement means and classification means. The spatial arrangement means performs processing for spatially arranging an information group of a first information type and an information group of a second information type based on relation between the information group of the first information type and the information group of the second information type. The classification means classifies the information group of the first information type based on the processing results of the spatial arrangement means.

Developing devices are provided adjacent to a light sensitive element. An intermediate transfer drum is provided adjacent to the light sensitive elements. After exposure of the light sensitive element, a first color or third color image is formed on the light sensitive element. On the other hand, after exposure of the light sensitive element, a second color or fourth color image can be formed on the light sensitive element. The first color image is transferred from the transfer unit to the intermediate transfer drum at the first transfer portion, and the second color image is transferred from the transfer unit at the second transfer portion so as to be superimposed on the first color image. Similarly, the third color image is transferred so as to be superimposed on the second image and the fourth color image is transferred so as to be superimposed on the third color image to the intermediate transfer drum. Accordingly, the first to fourth color images are superimposed. Thereby, downsizing of the device and cost reduction are achieved and image formation speed is facilitated.

In an image forming apparatus wherein a multiple number of image supports form developer images of different colors so that the developer images of different colors corresponding to the multiple number of image supports are superimposed to a recording medium to form an image, flywheels are set at the ends of the rotary shafts of multiple image supports corresponding to relatively highly visible colors while no flywheel or a flywheel having a different diameter or weight from that of the above is set for the image support corresponding to a less visible color so as to make the inertial condition different from that of the others.

In a copying processing performed several times from the depression of a copy button of a copying machine until the surface potential of the photoreceptor drum is stabilized, a voltage sufficiently high for correcting the rise characteristic of the photosensitive layer on the drum surface is applied to a charger. A main circuit having a controlling portion to realize this corrects the output voltage of the high-voltage generating circuit which applies a high voltage to the charger to a voltage value necessary for the drum surface to be charged at a stable potential level. The main circuit charges the drum surface at the stable potential level necessary for development from copying of the first sheet.

An encoder is connected to the drive system of the optical system of an image forming apparatus including an optical system for exposing a document image to a light and scanning the document image, a home position switch for detecting the optical system when it comes to the vicinity of the starting position, and a resist roller for setting the feeding start timing of a transfer sheet to the transfer section, and, on reproducing the above document image on a transfer sheet, when the pulse signals coming from the encoder, which are counted from the time when the optical system passes through the home position switch, reach the appointed value, the above resist roller operates.
摘要:
A paper supplying deck is insertable into and withdrawable from a paper supplying portion of a body resulting in electrical connection between the side of the paper supplying deck and the side of the body through a drawer-type connector when the paper supplying deck is inserted and interruption of such electrical connection when the drawer is withdrawn. The paper supplying deck has a paper carrying portion with a paper width setting mechanism and a variable resistor the resistance value of which is changed in dependence on the paper width setting mechanism, thereby changing an output paper width detecting voltage. On the wide of the paper supplying deck, a resistance which prevents the paper width detecting voltage from amounting to a power source voltage even though the resistance value of the variable resistor reaches a maximum value, is connected in series with the variable resistor. On the side of the body, a pull up resistance is connected with the connector to discriminate between voltages in the connector when the paper supplying deck is mounted and when the paper supplying deck is not mounted.
