摘要:
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.
摘要:
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.
摘要:
A sequence in the control apparatus of a copy machine performs sequence timing control of electronic equipment in a predetermined order and includes a counter for counting timing pulses received from an external device. A comparison register is included in the controller for comparing a count of the counter with data stored in a memory. The controller may also include a means for designating a channel in correspondence with a control object or a means for designating a channel in accordance with a program preset during the initialization of the equipment. Comparison data may be provided as a ROM code and transmitted to a data area in accordance with the control object preset at initialization so as to be selectively used.
摘要:
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.
摘要:
A control device in an image processing apparatus comprises a central operation processing unit and a plurality of operation control units controlled by the central operation processing unit, controlling a plurality of process means of the image processing apparatus and operating in parallel. Timer means for measuring the time for determining the control timing of the process means is provided in each of the plurality of operation control units.
摘要:
A control device for controlling plural analog devices in an image processing apparatus. The control device has a first controller for controlling the function sequence of analog devices, an analog-to-digital converter for obtaining digitals signals from the plural analog devices, and a second controller for controlling the analog devices to effect image processing by executing particular commands specified by the first controller, in response to the digital signals from the analog-to-digital converter.
摘要:
In order to automatically renew data using a modem which can simultaneously transmit/receive audio and data signal, there is disclosed an apparatus having a modem which can simultaneously transmit/receive audio and data signal (4 in FIG. 2), a discrimination circuit (flow chart in FIG. 5B) for discriminating if a communication partner is a specific partner, and a control CPU (flow charts in FIGS. 4A and 4B) for controlling the modem to perform a predetermined data communication together with an audio call on the basis of the discrimination result of the discrimination circuit.

摘要:
A communication apparatus which can communicate by a proper light intensity and can prevent excessive electric power consumption without providing light intensity measuring means on the reception side is provided. There are also provided communication apparatus and method, in which after a CPU issued a first message, a light emission intensity of an infrared LED is changed by the CPU so as to become the optimum state in accordance with the presence or absence of the response of a second message that is performed in response to the first message.
摘要:
An input-output integrated type electronic apparatus is arranged to enable the orientation of a displayed picture to be changed according to the orientation of the apparatus in a used state, whereby the facility with which the apparatus is used is improved. To change the display orientation, the content of a displayed picture is changed on the basis of a detected orientation of the apparatus.
