摘要:
There is disclosed a method of maintaining at a desired level the temperature of components in a copying machine which is in its idle state. An electric power is supplied members in the machine having an impedance component after the copying operation has been stopped. The voltage of the power must be set at a value lower than the rated voltage of the members.

A temperature control system comprises a heat sink heatable upon application of electric power thereto, an AC power source for heating the heat sink, temperature detector means for detecting the temperature of the heat sink, and control means for controlling the electric power applied to the heat sink in accordance with an output signal from the detector means so that the heat sink maintains its required temperature. The control means is operable to cause application of a full power of the power source to the heat sink at the initial heating stage thereof and application of a partial power of the power source to the heat sink when the temperature thereof is in the vicinity of the required temperature.
摘要:
A temperature and humidity compensating device is provided in electrophotographic apparatus including a photosensitive medium having a photoconductive layer, an image forming unit for forming an electrostatic latent image on the photosensitive medium, a heat source disposed near the photosensitive medium for heating the latter, a temperature detector disposed remotely from the heat source for detecting the temperature of the photosensitive medium, and control means for controlling the heating of the heat source so that the temperature of the photosensitive medium detected by the detector is not lower than the ambient temperature. Thus, the photosensitive medium may be prevented from deterioration due to falling temperature and moisture absorption, thereby permitting a normal image formation to be achieved.

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.
摘要:
A multiple-mode copying apparatus provided with a copy mode selector; and a first controller for causing, in response to the function of the selector, the copying operation to be conducted according to a particular copying mode thus selected. An original document feeder is also provided together with a second controller for causing, when the feeder is set in an operable condition, the copying operation to be conducted according to a particular mode without a previous selection having been made by the selector.
摘要:
An image forming system comprises means for image forming program modules one for each task and a plurality of monitor means for controlling a program. A predetermined one of the monitor means divides the program modules into blocks in accordance with a control mode, controls the blocks and controls the program in cooperation with the plurality of monitor means.

A copy machine has an original feeder for feeding an original document to a predetermined position, image forming apparatus including an original scanning unit, for forming an image of a positioned original onto a copy sheet, a copy feeder for feeding a copy sheet after the start of the feed of the original but before scanning is begun, a jam detector for detecting jamming of a fed original document, and control circuitry for controlling the image forming apparatus in accordance with the output of the jam detector.
摘要:
A management server (2) communicates with relay units (3) through a LAN, the relay units (3) are capable of communicating with wireless terminals (5), which are divided into groups, by short-range wireless communication, and the management server (2) transmits and receives information with the wireless terminals (5) through the relay units (3). A basic frame contains a synchronization signal for synchronizing the wireless terminals (5) to the relay units (3) and a data group for the respective wireless terminals (5). The wireless terminal (5) receives self-addressed data while synchronizing with the relay unit (3) by means of the synchronization signal. The management server (2) has a fast mode in which a duration of the basic frame is generated in T1 seconds and a normal mode in which the duration is generated in T2 seconds. In this case, T1
