摘要:
The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.

An information processing apparatus acquires identification information which specifies an interpreting program for interpreting a device control language, the specified interpreting program being operable in an external device connected to the information processing apparatus. It is discriminated whether a selected first control program corresponds to the device control language interpreted by the specified interpreting program. If it is discriminated that the selected first control program does not correspond to the device control language interpreted by the specified interpreting program, a second control program corresponding to the device control language interpreted by the specified interpreting program is selected from a plurality of control programs. Data is output to the external device using the first control program or, if it is discriminated that the first control program does not correspond to the device control language, the selected second control program.

A printing system including a client terminal and a separate printer connected to the client terminal via signal cables. The client terminal includes a print conditions transfer mechanism which transfers print conditions entered by an operator and a document component generating mechanism. The document component generating mechanism divides a document entered by the operator into a document block, converts data in each document block into printable data, and generates document component. A number of the document component is equal to the number of the divided document blocks so that the document components and the divided document block correspond to each other on a one to one basis. The printer includes a print conditions storing mechanism which receives and stores the print conditions, a document component storing mechanism which sequentially stores and transmits the transferred document component, and a composite print processing mechanism. The composite print processing mechanism generates image data according to the print conditions and corresponding to each of the document components and accumulates the generated image data to print the document with the accumulated image data upon receiving a print start instruction.

A client/server system includes a client and a plurality of servers which are connected via a communication network. The client includes an object-oriented middleware and client-form image processing objects. A middleware processing device converts a client-form request from a request input device into a standard-form request readable by the middleware. A request transmitting device transmits the standard-form request to the network. Each of the servers includes an object-oriented middleware, image processing units, and image processing objects. The image processing objects of each server have specific interfaces to the image processing units, any one of the image processing objects allowing a corresponding one of the image processing units to be executed in response to a server-form request. A middleware processing device of the server converts the standard-form request from the network into a server-form request, and transmits the server-form request to a selected one of the image processing objects so that a corresponding one of the image processing units is executed in response to the server-form request.

A plasma addressed electro-optical display device having a plasma cell comprising an anode electrode and a cathode electrode arranged in parallel in a plasma chamber in which a discharge is performed and a liquid crystal cell arranged near the plasma chamber and driven through a virtual electrode formed in the region discharged in the plasma cell, wherein as the discharge gas sealed in the plasma chamber, use is made of one of the group of approximately 100 percent by volume of xenon (Xe); approximately 100 percent by volume of krypton (Kr); a mixed gas of xenon (Xe) and an inert gas other than xenon (Xe) or a stable gas; and a mixed gas of krypton (Kr) and an inert gas other than krypton (Kr) or a stable gas.
摘要:
A device for controlling an electrophotographic process such that a stable latent image is formed on a photoconductive drum in matching relation to changes in the characteristics of a photoconductor. Deterioration detecting sections classify, among the characteristics of the drum, a plurality of drum deterioration factors including the amount of wear, electrostatic fatigue, fatigue due to exposure, the degree of continuous use, temperature and humidity by a time range such as long-term/short-term/day or by a number-of-copy range such as great amount/small amount/day-amount. The deterioration detecting section quantizes each of such degrees of deterioration of the drum by fuzzy inference. A latent image manipulation value determining section determines a charge manipulation value and an exposure manipulation value by fuzzy inference.
摘要:
An image forming method for forming an image by transferring toner image formed on a photoconductive element to a paper sheet or similar recording medium. Variable factors affecting image transfer, paper separation and paper transport characteristics are classified. An image transfer state, a paper separation state and a paper transport state are each estimated as a combination of membership functions of the variable factors to determine an image transfer condition, a paper separation condition, a paper transport condition and auxiliary conditions such that control is executed on the basis of the determined conditions.
摘要:
An electrophotographic process control device for controlling the supply of a toner in such a manner as to stabilize images against changes in the characteristics of a photoconductive element and in the concentration of the toner. An image density sensor measures the density of an image formed on a photoconductive drum. A scanner writes read image data representative of a document on the photoconductive drum. A determining section is responsive to the image density from the image density sensor and write image data from the scanner and representative of the area of an image for executing a predetermined fuzzy combination operation by using fuzzy rules registered beforehand and converts a membership function resulted from the operation to a non-fuzzy value to thereby determine a toner supply manipulation value.

In order to avoid a load change which occurs when seam O passes by the heads affect image information, a dyeing layer transfer head and recording heads are located in equal intervals having length P, which is obtained by equally dividing an entire circumference K of a recording intermediate belt by n (n is integer), and, given that the position of the seam of the recording intermediate belt, which does not have an end obtained by coupling two ends of a belt body of a band shape, is origin O, images are formed in portions except for portions at origin O, or at a distance of 1×P, 2×P, . . . (n−1)×P from origin O. In this way, it is possible to prevent deterioration in the image quality, such as a stripe line in an image formed by an image forming apparatus.

Common portions of applications are extracted as common system service. A platform is formed by the common system service and a general purpose OS. A printer application, a copy application, and various applications are mounted on the platform. As a result, each software (application) corresponding to a printer, a copier, a facsimile device, and so on can be developed efficiently and the productivity of the apparatus as a whole can be improved.
