In a cable connecting a plurality of printed-circuit boards, terminals of connectors to which conductors disposed adjacent to conductors that supply power are connected are connected to ground via respective capacitors.

Electronic apparatus

An image forming apparatus includes a first power source configured to supply power for driving a load to be used for image formation via a first power line, a load control circuit configured to control driving of the load, a control circuit configured to output control data for the load control circuit to control the load, a second power source configured to supply power for the load control circuit via a second power line provided separately from the first power line, a superimposing circuit configured to superimpose the control data output from the control circuit onto the second power line, and a separation circuit configured to separate the control data from the second power line, on which the control data is superimposed and sent, and to output the control data to the load control circuit.

Image forming apparatus

An apparatus is provided that can perform distributed control for a plurality of operation units, without concentrating control in a single device. The apparatus includes a plurality of modules that respectively correspond to a plurality of operation units, each module including a communication device, a functional block setting device and a functional block connected with a corresponding operation unit. The functional block has a register that holds, in an updateable condition, control values relating to various controls of the corresponding operation unit. Each module is triggered by an operation start signal input to a start terminal of the communication device to start an operation for controlling a corresponding operation unit in accordance with each control value held in the register device.

Image forming apparatus with a plurality of modules receiving a common trigger signal

A document reading apparatus includes a housing that has conductive characteristics, a platen that is provided with the housing and that has translucency, and an image reading unit that is arranged so as to be movable in the housing and that reads a document placed on the platen. In particular, at least one opening is provided in a region of the housing that overlaps with the image reading unit as viewed in a direction orthogonal to the platen.

Document reading apparatus

The image forming apparatus includes, even when an abnormality of operation occurs in any of a plurality of modules to which an assigned operation in a plurality of operations for an image formation is assigned and which autonomously executes the assigned operation, each of the modules can autonomously perform a particular operation for eliminating an abnormality of operation at a module in which an abnormality occurs. When detecting the module in which the abnormality of operation occurs based on operation abnormality generation condition information in each of the modules stored in the shared data module, the plurality of modules provided in the image forming apparatus each perform an operation (a particular operation) for eliminating the abnormality of operation in accordance with the module in which the abnormality of operation occurs and the contents of the abnormality of operation. Of the plurality of modules, a module which finally performs the particular operation notifies the occurrence of abnormality of operation to a controller module.

Image forming apparatus and control method for the same

An information processing apparatus determines whether an authentication portion on an image forming apparatus side can authenticate user authentication information input on the information processing apparatus side. If it is determined that the authentication portion on the image forming apparatus side can authenticate the user authentication information input on the information processing apparatus side, transmission of image data from the information processing apparatus to the image forming apparatus is controlled.

Information processing apparatus, image forming apparatus, image forming system, information processing method, and image forming method

An image reading apparatus having a security function that realizes highly precise authentication and high operability while suppressing an increase in manufacturing cost. An originalis placed on a platen glass, and an authentication cardis placed on a security information reading section. An image sensorreads an image of the originalplaced on the platen glassand security information stored in the authentication cardplaced on the security information reading section. A control sectioncontrols processing of the image of the originalread by the image sensorin accordance with the security information read by the image sensor

Image reading apparatus and method of controlling image reading apparatus

A digital electronic apparatus includes a plurality of units and a cable. The plurality of units have metallic housings and are combined such that surfaces of the metallic housings are opposed to each other. The cable is laid on a surface of the metallic housing of at least one of the units. The surface on which the cable is laid is other than the surfaces of the metallic housings that are opposed to each other.

Digital electronic apparatus with suppressed radiant noise

The states of plural image output apparatuses are sensed. Then, an image output apparatus, which will supply image data, is selected according to a size of an image output job on the basis of image data and the states of the image output apparatuses in such a manner as to reduce an electric power consumption required for outputting images.

Information processing apparatus, information processing method, image output system, electric power consumption control method for image output system, and storage medium therefor

It is provided an image formation apparatus which forms a color image by superimposing an image corresponding to each of plural-color image data on an image support body, comprises a light beam generation means for generating a light beam which has been modulated according to each-color image data included in the plural-color image data, a rotation polygon mirror for performing scanning on a photosensitive body by using the light beam, a position signal generation means for outputting a position signal representing a scanning position on the photosensitive body, in case of performing the scanning on the photosensitive body by using the light beam corresponding to first-color image data included in the plural-color image data, and a control means for controlling rotation driving of the rotation polygon mirror corresponding to second and subsequent colors, in response to the position signal. Therefore, it can be obtained a new method for superimposing plural-color plane images without aberration in position, in case of forming a color image by superimposing the plural-color plane images on the image support body such as the photosensitive body, an intermediate transfer body, a recording paper on a transfer body or the like.
