Abstract: A continuous plural page copying method for a copier determines the size and lengthwise direction of a document which is laid on a glass platen, and produces magnifications on the basis of a relationship between one half of the size of the document in the lengthwise direction and the size of the papers selected. Consecutive pages of the document are reproduced continuously with no regard to the orientation of the document on the glass platen relative to the scanning direction of a scanner. The method reproduces an image on a paper while desirably matching it to the size of the paper.

Abstract: A machine has a control panel with a plurality of keys controlling various functions. A display exhibits prompts as to the proper operation of the machine. An operator can learn the functions of the keys by manipulating them and observing the resulting prompts. The display additionally exhibits maintenance and (in a diagnostic mode) diagnostic prompts. Sensors respond to various maintenance or diagnostic conditions. Signals from the sensors cause a storage means to supply corresponding prompts to the display to prompt the needed maintenance or diagnostic procedure. When the appropriate procedure has been performed, additional prompts for subsequent procedures will be displayed if appropriate.

Abstract: A power supply control device for a copier of the type having a timer therein is disclosed. The device allows a power supply of the copier to be turned on and off at any desired time which is set through ten keys. Data entered through the ten keys are loaded in a store. The data read out of the store and present time data output from the timer are compared and, as they compare equal, a power supply driver turns on the power supply. Guidance displays are referenced in the event of entering data.

Abstract: A copier with an image editing function which extracts desired areas of a plurality of documents in an analog fashion and allows them to be edited on a single transfer sheet. The copier includes an erasing device for selectively erasing an image provided on a photoconductive element, a detaining device for temporarily detaining a transfer sheet, an image inputting device for inputting an image of an original document, and a display device for displaying an input condition. Desired areas of documents are specified and edited with the aid of displays and then copied. Where the specified areas of the documents overlap each other, one of them having priority over the other or a selected one of them is copied. The number of areas to be edited is open to choice. The specified areas are entered through editing keys and usual ten keys. The erasing device is driven by a controller which is responsive to digital signals which are derived from position setting knobs associated with two perpendicular scales.
