摘要:
An integral document processing apparatus comprising an electrophotographic copying system and a facsimile transmission system. A document fed from a common document storing unit is guided selectively to a first document read unit included in the electrophotographic copying system or to a second document read unit included in the facsimile transmission system by a document feed passage changeover mechanism which is operated selectively by an operator. A document delivered to the first document read unit is copied by the electrophotographic copying system. A document delivered to the second document read unit is converted into a corresponding electric image signal, and then the electric image signal is applied to a communications line.
摘要:
The copying rate of an electrophotographic copying machine of constant paper advance speed including a toner image fixing unit which is selectively preset to predetermined values in increment inverse relationship to the thickness of the copy sheets employed, so that copy sheets of greater thickness are fed to the fixing unit for lesser feed rate than the thinner standard sheets, whereby the copy sheets are adequately heated at the different thicknesses. Following the termination of a copy sequence of thicker sheets at reduced feed rate, the copy machine automatically reverts to its rate setting for standard thickness sheets. In copying with standard thickness sheets, the period of the first copying cycle is greater than that for subsequent sheets and the copying rate with the thicker sheets is the same as that for the first copy with standard thickness sheets. A microcomputer network with a rate selector switch programs the copying machine in the above manner.
摘要:
A copier including a detector for detecting malfunctions in the copier or nonoperative conditions of the copier; and a system for storing voice signals corresponding to the detected malfunctions and nonoperative conditions and a voice producer for producing a voice corresponding to each of the stored voice signals. When an operator attempts to operate the copier, a voice is produced to inform the operator of the malfunction or nonoperative condition of the copier. Voice is produced only when manual-starting or door-opening is sensed.
摘要:
An improved operator controlled system for a copying machine to minimize user error and to provide a compact control console. An information display member is capable of sequentially displaying an identification of discrete operating features, such as number of copies, etc. A memory is capable of storing a predetermined set of first command signals for each discrete operating feature. A common set of control members permits the user to selectively generate second input command signals relative to any specific operating feature. These same control members are capable of inputing signals for a number of different operating features. The copying machine is capable of discriminating between the input command signals and the particular operating feature. The resulting operation of the copying machine would be in accordance with the predetermined standard set of machine functions or any combination thereof of operator inputed command functions. The specific discrete operating features are automatically displayed after a predetermined set time to minimize any error resulting from operator forgetfulness.
摘要:
A copying machine wherein a magnification ratio can be changed substantially continuously within a predetermined range, comprising means for setting a longitudinal magnification ratio of a copied image against an original and a lateral magnification ratio of a copied image against the original independently, image shifting means for shifting an image projected on a photosensitive drum in a direction away from a paper separation belt, first calculating means for calculating a lateral magnification factor, second calculating means for calculating a longitudinal magnification factor, and means for modifying the longitudinal and lateral copy magnification ratios respectively using the selected magnification ratio, the longitudinal and lateral magnification factors, whereby an image can be formed on the copy paper, preventing image drop out.
摘要:
An improved paper transport control device for use in a mechanical arrangement including a manual paper feeding mechanism, in which at least one of the mechanical operations, such as jam detection, is caused to be inoperative when the paper is drawn out within a predetermined period of time after the paper has been fed manually, so as to enable the immediate resumption of the next mechanical operation even if the paper is drawn out after the manual paper feeding has been started, thus significantly improving the working efficiency of the device.
