Control device for image forming apparatus

An image processing system includes a plurality of memories for storing (1) a procedure control program and (2) a task program for automatic closed loop control. Each program is grouped into a plurality of groups of programs in response to one of a plurality of selectable stages corresponding to priority required to execute an image processing. Each group of programs is task scheduled and one of the stages is selected. The task schedule is controlled in response to the selected stage and the group of programs is supervised corresponding to the selected stage.

Image forming system with task scheduling and executing back on program

An image processing controller comprising a pulse control signal generator for controlling a load. A memory is provided for storing parameters, such as the period and duty factor of the pulse control signal. The parameters are transferred from the memory to the pulse control signal generator. The pulse control signal generator generates a pulse control signal having a predetermined pulse width at a predetermined period, in accordance with the parameters.

Pulse width modulation input/output controller for image processing

A control system suitable for control of an image forming apparatus such as a copying machine having a plurality of objects to be controlled. This system comprises a plurality of control units to individually and independently control those objects to be controlled, a monitor control unit to monitor those control units, and a system bus which is commonly connected to the control units and monitor control unit. The control units time-sharingly and cyclically execute their control operations by time-sharingly occupying the system bus one by one. The monitor control unit operates in parallel with the control units. The control units and monitor control unit are formed on the same semiconductor substrate consisting of, for example, Si or GaAs. The system bus may be a LAN bus or an optical fiber. With this control system, each control unit can execute its own control operation irrespective of an interruption request, so that the processing program procedure is simplified and a reliability of control is also improved.

System for controlling image formation

An information processing apparatus includes a processor for performing various information processing operations in accordance with an instruction from an operator, a bioinformation sensor for detecting a mental condition of the operator, and an output unit for outputting corresponding information to the operator based on the detected mental condition. The operator is relaxed by the information output from the output unit.

Operator mental condition detector

An image processor includes a light source, a scanner for scanning an original document using the light source, an imager for forming an image on the basis of light reflected from the original document and a light from the light source, a controller having a plurality of electro-mechanical transducer elements arranged in a light path from the light source to the imager, a generator for generating image data, and a driver for driving the controller in accordance with the image data. The driver drives the light controller in accordance with the image data, thereby causing the imager to form an image corresponding to the image data. The light source is adapted for forming an image corresponding to the original document and an image corresponding to the image data.

Image processing apparatus

There is disclosed a novel control system in an electronic apparatus such as a copier, in which intelligent registers are provided in addition to the microprocessor and execute control under predetermined conditions. The microprocessor interferes with the execution of control by the registers only when the conditions become aberrated from the predetermined value, and is therefore used for other tasks.

Electronic load drive control apparatus

An audio signal transmission system includes an input section, an output section and a transmission section interposed therebetween. The transmission section analyzes the spectrum of the input audio signal and performs signal processing based on the result of this analysis and in accordance with the physical response characteristic of the output section.
