Abstract:
An electrophotographic copying machine capable of editing function comprising: a table for setting a document; scan means for scanning the document; first input means for providing first and second data to specify positions in the scanning direction; second input means for providing third and fourth data to specify positions in the direction perpendicular to the scanning direction; memory means for storing the provided data, which comprises a first memory area for storing smaller data provided by the first input means, a second memory area for storing larger data provided by the first input means, third memory area for storing smaller data provided by the second input means, and a fourth memory area for storing larger data provided by the second input means; a means for specifying an area on the basis of the data stored in the memory means; and copying means for reproducing a image of the document corresponding to the specified area.
Abstract:
An electrophotographic copying machine is provided with a leaf document circulation mode (LDC mode) in which an optical scanner is fixed under a light transmission part of a platen glass and an original is made to pass over the optical scanning mechanism with an automatic document feeder mounted on the platen glass. To prevent the light-fatigue of the photosensitive drum caused by the light passing through the platen glass and incident on a photosensitive drum through an optical system when the automatic document feeder mounted on the platen glass is opened in the LDC mode, the open/close condition of the automatic document feeder is detected with a sensor and when it is opened the optical scanner is moved to a position where the light incident through the platen glass does not strike upon the photosensitive drum.
Abstract:
A copying machine capable of correctly counting the number of printed copying papers, and which is capable of interrupting the counting task when some copying papers stored in an intermediate storage unit or marking papers for classifying printed copying papers are discharged without forming any image thereon.
Abstract:
A copying apparatus capable of performing a first copy operation and a second copy operation on a sheet of copy paper in a duplex copy mode or a composite copy mode, a first group of input copy conditions are set to a first predetermined state if the second copy operation does not start within a first predetermined period of time after the first copy operation, and a second group of input copy operations are set to a second predetermined state if the first copy operation of the subsequent cycle does not start within a second predetermined period of time after the second copy operation, the first predetermined period of time being longer than the second predetermined period of time.
Abstract:
A copying apparatus comprises a plurality of sheet storing trays, a detector for detecting a quantity of sheets of paper in each tray, and an indicator. The indicator displays a capacity of a tray selected for copy operation and also displays the remaining quantity of sheets in that tray in response to the detector.
Abstract:
A copying machine capable of correctly counting the number of printed copying papers, more specifically, capable of interrupting the counting task when some copying papers stored in the intermediate storage unit or marking papers for classifying printed copying papers are discharged without forming any image thereon.
Abstract:
In an image forming apparatus of the type including a plurality of functional modules each having particular functions proper to the unit, a control system having a master control unit and a plurality of subsidiary control units respectively in control of the individual functional modules wherein each of the plurality of subsidiary control units operates principally under the control of the master control unit through a communication network of the common interface bus type but is operable independently of the master control unit when required or preferred by the subsidiary control unit per se. At least one of the functional modules is provided with a standard mode of operation and a local mode of operation. The standard and local modes are incompatible with one another.
Abstract:
A photocopying apparatus has the capacity to edit desired portions of a document image onto copying paper. A memory is provided for storing area data specifying a specific area of the document. Coordinates of the specific area can be reset in an initial value memory upon the operator selection of an edition mode to facilitate easy selection of a desired portion of the document image.
Abstract:
A copying apparatus comprises at least one sheet storing tray, at least one detector for detecting a quantity of sheets of paper in a tray, and an indicator. The indicator can display a capacity of a tray selected for copy operation and can also display a remaining quantity of sheets in that tray in response to the detector.
Abstract:
A data communication control system for an apparatus which may be selectively equipped with two or more functional modules each having predetermined functions, the control system having a plurality of subsidiary control units respectively in control of the functional modules, a main control unit operative to communicate with each of the subsidiary control units and a data transmission network interconnecting the main control unit and each of the subsidiary control units to allow full-duplex communication therebetween, each subsidiary control unit being operative to generate mode data designating any of the functions assigned to the particular subsidiary control unit and transmit the mode data to the main control unit, wherein, when mode data designating any function is generated by one of the subsidiary control units and is sent to the main control unit, the main control unit transmits to each subsidiary control unit data designating the function designated by the mode data if the main control unit determines that the execution of the particular function is allowable, or the function designated by the mode data received prior to the currently received mode data if the main control unit determines that the execution of the function designated by the currently received mode data is not allowable.
