摘要:
An image reading apparatus which reads out a document placed face-up by scanning optically from above the document, having a document change detection means, and when a document is not changed, a reproducted image density is controlled by using a previous result of the document ground brightness detection without detecting newly. Further, an image reading section is arranged on a document table which a bookform document is placed upward and an auto-document feeding unit for conveying a sheetform document is provided, where by a conveyed sheetform document is read out by a sensor at a fixed focal position.

A facsimile apparatus is provided with an overwrite mode of operation and an append mode of operation. The image data for a document that is to be registered for polling transmission is stored in a memory in a manner which permits the image data to be easily modified, and additional data appended thereto. In the overwrite mode, previously stored data is automatically erased, and new image data is stored in the memory in its place. If the amount of new image data is greater than the amount of data that was previously stored, the additional data is stored in a manner which links it to the area where the previously stored data was located. In the append mode, the new image data is similarly stored in a manner which links it to previously stored data. There is no need to erase or modify the originally stored data in this mode.

The invention relates to an image reading apparatus for reading images of original documents by moving the original relative to a stationary image reader. A single image reader is used in a first embodiment. When reading the image of a first side, the single image reader is stationary at a first position to read the original. When reading the image of a second side, the single image reader is moved to a second position corresponding to the size of the original, and reads the image of the second side while said image reader is stationary at the second position. The image reading apparatus of the second embodiment uses a stationary first reader for reading a first side of an original, and a movable second image reader for reading a second side of an original. The image reading apparatus of the second embodiment changes the position of the image reader in accordance with the size of the original.

A sheet storing apparatus which is attachable to a copying machine and a method of controlling it, wherein sheets ejected from the copying machine one after another are stacked in order. A detector for detecting the condition of the sheet transportation is installed in a sheet transporting section thereof, and a control section controls the timing of driving a sheet storing section, a sheet transporting section and a sheet aligning section, based on an output of the detector and data on the speed of the sheet transportation in the copying machine. The control section has a timer for determining the timing of driving each section, and the value of the timer is adjusted in accordance with the data on the speed of the sheet transportation.

A copying apparatus comprising a feeding unit which can be operated in a single manual feeding mode that a sheet of copying paper set manually is fed out and in a multiple manual feeding mode that a plurality of copying paper set manually is successively fed out sheet by sheet and a refeeding unit for feeding copying paper on each sheet of which an image is formed once to an image transfer portion again. The refeeding unit is controlled, when the single manual feeding mode is selected, to perform the refeeding operation each time an image has been formed on a sheet of copying paper fed from the feeding unit, and when the multiple manual feeding mode is selected, it is controlled to perform the refeeding operation after the completion of the successive feeding and image forming operation toward all the sheets set manually.

A facsimile machine in accordance with the present invention includes a reading device for reading an original image to be transmitted, a memory for storing the read image data, a first transmission device for transmitting the image data stored in the memory to an external device, a second transmission device for transmitting the read image data to an external device in parallel with the reading operation by the reading device, and a controller for activating one of the first and second transmission devices based on the remaining amount of the storage capacity of the memory.

When an original fed by an original feeding portion is mounted at a predetermined position on a platen glass, a scanner starts traveling in one direction from its home position, and scans the original. When the scanner completes scanning, the original read out is discharged, and the next original is fed. However, the scanner does not return to its home position. The scanner is held at the position. When the next original is mounted at a predetermined position, the scanner travels in a direction opposite to a direction for the previous original from the position to carry out scanning.
摘要:
A digital copier being provided with a memory function which enables the operator to set a plurality of copying conditions in a single setting operation before copying operations are initiated so that the copying operations are performed in series or in parallel based on the individual copying conditions being set. Even when the copying operations are ongoing, the digital copier also enables the operator to change the setting of the copying conditions such as the number of copies, magnification for copying, and paper size, along with the sorting mode, so that the copying operations are performed based on the changed conditions thereafter. Accordingly, the setting of the copying modes for every copying mode, which has conventionally been required, is not necessary any more. This improves copying efficiency and also realizes flexible operation even when a plurality of copying modes are set, so that the copying function of the digital copier is significantly improved.

An image displaying device includes a first display portion capable of changing display contents and provided at a surface side of a main body, a second display portion capable of changing display contents and provided at a lower surface side of the main body and a detector which detects a turning-over of the main body. The display contents of the first or second display portion is changed by a display controller depending on detected results of the detector.
