摘要:
An image forming apparatus comprises latent image forming means for forming a latent image on a photosensitive medium, reference latent image forming means for forming a reference latent image adjacent to the latent image, a plurality of light-emitting means disposed at intervals of a pitch D equal to or smaller than the width l of the reference latent image, and means for drivingly controlling the plurality of light-emitting means in accordance with the size of the latent image.
摘要:
An improved image forming apparatus for controlling image density at an optimum level. The image forming apparatus has a plurality of detectors for detecting an original image density. The detectors have mutually different detecting characteristics, wherein image forming conditions are controlled based on the outputs of the detectors. Control may be effected in accordance with a comparison of the detected values, and in accordance with a selected operation mode.
摘要:
A device for controlling plural loads with phase locked loop control method by means of reference signals of different phases in order to avoid peak in electric power consumption.
摘要:
An image reproducing apparatus with or without an ADF has an optical system for scanning an original, a developing unit, a fixing unit, a differential amplifier, and a microcomputer. Original image density can be measured properly in any mode of the apparatus. The image is reproduced to have optimal density by a lamp control voltage from the differential amplifier. Toner deficiency or the like can be indicated with a few number or displays and/or indicators. Upon detection of toner deficiency or the like, the current copying cycle is completed first and the apparatus is stopped. The copying operation can be resumed after the toner deficiency or the like is eliminated.
摘要:
A copying apparatus comprises an optical lens, drive means for driving the optical lens, and control means for controlling the drive means. The control means changes over the output of the drive means in accordance with the distance of movement of the optical lens.
摘要:
An equipment control apparatus in a system having an input unit for entering data on the conditions of equipment from the equipment, a communication unit for communicating with the apparatus located at a distance, and a control unit for exerting control in such a way as to transmit the data to the apparatus located at a distance through the steps of interrupting communication once on receiving a call from the apparatus requesting the data and then calling the apparatus located at a distance via the communication unit.
摘要:
A machine monitoring apparatus includes an input device for receiving data from a machine, the data being indicative of a condition of the machine, a storage device for storing the received data, a communication device for communicating between the storage device and an external apparatus installed at a position separate from the machine, and a control device for inhibiting the communication device from transmitting the data stored in the storage device when a power supply for supplying the machine with electric power is turned off while the data is being received by the input device.
摘要:
An equipment controlling apparatus is composed of a counter for counting the operational number of the equipment, memories for storing data indicating the state of the equipment, a communication device for communicating on the stored data with a centralized control apparatus, which controls the communicated data intensively, and a controlling device for causing the stored data to be transmitted to the centralized control apparatus when the counter has counted a predetermined value.
摘要:
A method of managing an image forming apparatus by a remote computer comprises the steps of detecting an abnormal state in the image forming apparatus, transferring an error code corresponding to the kind of the detected abnormal state to the computer, selecting a predetermined program according to the transferred error code by the computer, transferring the selected predetermined program to the image forming apparatus by the computer, and executing the transferred predetermined program by the image forming apparatus. The predetermined program is a diagnosing program to examine the causes of a failure in the image forming apparatus.
