摘要:
A multiple color image forming apparatus, wherein colors or kinds of copying paper contained in paper feed cassettes as well as colors of developers contained in a plurality of developing devices are detected to prevent image forming, which is indistinguishable due to mismatching between the color or kind of copying paper and the color of developer, and the developing device containing the developer of suitable color for the color or kind of copying paper is automatically selected in response to the detected result of the color or kind of copying paper and the color of developer to prevent misforming of the image and to improve the operation easiness.

An image processing system having operating and stand-by modes of operation which are to be selectively put into effect, including a plurality of slave data processors each operative to execute a set of predetermined functions assigned thereto, a master data processor for controlling the operation of each data processor, the master data processor being operative to output a data processing command requesting any of the slave data processors to execute any of the predetermined functions assigned to the slave data processor and a control command predominant over the communication of data dictating the operation of each slave data processor, and an interface bus providing connection between the master data processor and each slave data processor for allowing transmission therethrough of the data processing command and the control command to any of the slave data processors, the master data processor being operative to detect a state in which the master data processor is currently coupled to any one of the slave data processors through the interface bus to allow transmission of the data processing command or the communication control command to the particular one of the slave data processor, wherein, in an operating mode of operation of the system, the data processing command or the control command is distributed through the interface bus exclusively to the particular slave data processor which is detected to be currently coupled to the master data processor.

A program replacement device is incorporated in a computer system having a CPU and a program memory in which first programs to be executed by the CPU are stored. The program replacement device includes a RAM employed as the program memory and having a write enable terminal, and a protection circuit interposed between the write enable terminal of the program memory and a write signal outputted from the CPU. The protection circuit includes a push switch for instructing program replacement with respect to the program memory, a pulse generating circuit for generating a pulse signal having a given time interval in response to an instruction from the push switch, and a gate circuit for making, only when the pulse signal is generated, the write signal outputted from the CPU valid with respect to the write enable terminal of the program memory. The program replacement device further includes an interruption generating circuit for generating in the CPU an interruption required to write second programs in the program memory in response to the instruction from the instruction section, thereby replacing the first programs by the second programs.

An image forming apparatus capable of making copies under either predetermined standard copy conditions or copy conditions optionally set by an operator. After the final key input, or at the completion of a copying process, a first timer is set to count a predetermined time period. When the first timer finishes counting, the copy conditions are automatically set to the standard conditions. The above apparatus is provided with a guidance mode for the purpose of explaining the method for setting the functions and copy conditions within the apparatus to an inexperienced operator. In the case where the guidance mode is set by the operator, a second timer is set to count a predetermined time period longer than the time period counted by the first timer. When the second timer finishes counting, the copy conditions are automatically set to the standard conditions.

A present sheet transporting apparatus for use in a copier measures the time for the sheets to travel a specific distance and corrects a period of time counted by a paper jam detecting timer. Therefore, if slight wear of rollers delays an arrival time of sheet, the apparatus does not detect a jam because such a delay causes no particular trouble to copying operation.

An image forming apparatus according to the invention includes a document transporting device for transporting a plurality of documents set on a tray one by one to a platen, copying mode selecting keys for selecting a first copying mode for forming images from the plurality of documents under first copying conditions and a second copying mode for forming an image from a particular one of the documents under second copying conditions, and a control device for executing the image forming operation under the copying conditions of the copy mode selected by the copy mode selecting key.
摘要:
An image duplicating apparatus of the type having an IC-card controlled mode of operation in which are to be established standard conditions for copying operation when predetermined initial requirements are satisfied in the absence of an IC card set in the apparatus, and IC-card optional conditions for copying operation when the predetermined requirements are satisfied in the presence of an IC card set in the apparatus. The apparatus includes a control for selecting duplicating conditions within the apparatus and a memory for storing data representative of the selected duplicating conditions in responses to a first state in which the IC-card is not set in the apparatus, and for storing data fetched from the IC-card in response to a second state when the IC-card is set in the apparatus. The control is responsive to transition from one state to the other for establishing either the standard conditions or the optional conditions for a copying operation.

A copying apparatus copies an image of each original document either in a one-side copy mode or a both-side copy mode during a cover copy mode. The copying apparatus is capable of selectively supplying colored copy sheets for a cover page and ordinary white copy sheets for the other pages. A controller controls the copying apparatus such that the image of one cover page is copied on one side of a colored copy sheet, the image of each table of contents is copied on one side of a white copy sheet, and the image of each of the other content pages is copied on both sides of a white copy sheet.

An MFP stores information of a web service for permitting use with respect to each user, and information for limiting a use of its function. When there is a web service allowed to be used by the logged in user, its list is displayed. When a linked function with the selected web service is not allowed to be used, a massage to the effect that is displayed and when the use of the function is limited, limited contents are displayed to confirm the use of the web service.

In order to enable a still image to be checked while preventing leakage of confidential information contained in the still image, an MFP includes: an image acquiring portion to acquire a still image; an encoding portion to generate encoded data by encoding the acquired still image using an encoding key stored in advance; a decoding portion to decode the encoded data using the encoding key or a decoding key corresponding to the encoding key; and a transmitting portion to externally output the decoded still image in an electronically non-recordable form.
