摘要:
A copying machine wherein a magnification ratio can be changed substantially continuously within a predetermined range, comprising means for setting a longitudinal magnification ratio of a copied image against an original and a lateral magnification ratio of a copied image against the original independently, image shifting means for shifting an image projected on a photosensitive drum in a direction away from a paper separation belt, first calculating means for calculating a lateral magnification factor, second calculating means for calculating a longitudinal magnification factor, and means for modifying the longitudinal and lateral copy magnification ratios respectively using the selected magnification ratio, the longitudinal and lateral magnification factors, whereby an image can be formed on the copy paper, preventing image drop out.

An improved copying magnification capacity is provided to an electrophotographic copying apparatus. The copier has a numeric data display that can disclose numeric data that can be manually input into the machine. The numeric data can be stored in a memory as a predetermined copying magnification value. The copier has the capability of establishing a copying magnification value that can be easily adjusted when the magnification of an actually obtained copy deviates from an established desired value. The stored numeric value can be used in the control for setting a magnification value.

A copying apparatus includes a switch checking system for examining whether or not a switch to be operated through the operation of the copying apparatus is normally operated. The copying apparatus is provided with a switch to be operated through the operation of a movable member and a controlling apparatus having a program set to output a given controlling signal through judgement of the operating condition of the switch. The controlling apparatus has a controlling mode for switch checking operation and a program for displaying the switching condition when the switch has been operated in the controlling mode and the switch checking is adapted to be performed through the mode switching of the controlling apparatus.

A data transmission system includes a host CPU having an output terminal for repeatedly producing a predetermined number of data blocks in a predetermined sequence in a repeated manner. Each data block is defined by a sequence code for identifying each data block and specific data followed by the sequence code. A plurality of slave CPUs are provided. The host CPU is connected to each slave CPU through a bus structure for the mutual data transmission. Each slave CPU receives all the data blocks and selectively extracts only the necessary data for use in each slave CPU and produces data from its output terminal at a given period within one cycle of the predetermined sequence. The given period for one slave CPU differs from that of another slave CPU, thereby transmitting data to the host CPU without any interferences.

A programmable copying apparatus is provided which permits an operator to be informed of the exact time that the copying operation input by him into the machine will be completed, even with multiple copying operations.
摘要:
An operation device for use in a copying machine which comprises a visual display unit on a copy start button of the copying machine for displaying various operational states of the copying machine by different figures or patterns representing the contents of the states of the copying machine. The patterns of the display unit is controlled in response to signals fed from a control device of the copying machine.

A copying machine includes a drive motor for driving the copying machine, a device for generating a start signal for starting the drive motor, an auto-shut device for stopping the drive motor a predetermined period of time after the completion of a copying operation, and a mechanism for carrying out a multi-copying operation in which a plurality of copying operations are carried out sequentially. The copying machine further includes a device for producing a first signal in response to each copying operation, a device for cancelling the auto-shut device and for starting, without any stop of the drive motor, a next copying operation, in a case when the start signal is generated before completing the count of the predetermined period of time for the auto-shut mechanism, or when the multi-copying operation is carried out, a device for discriminating whether the drive motor is in an on-state or a off-state, a device for producing a second signal in response to the generation of the start signal during when the discriminating device discriminates that the drive motor is in off-state, a counter device for counting the first and second signals, and a display device for displaying a number counted by the counter device.

A computer-controlled paper feeder comprises at least first and second supply units from which respective recording materials are supplied one at a time towards a processing station. There is provided a size detector for detecting the size of the recording material contained in respective cassettes inserted in the associated first and second supply units and an emptiness detector for detecting the presence and absence of the recording material in any one of the cassettes in the first and second supply units. These detectors are so correlated with micro-computer that, when the recording material in one of the cassettes has been consumed and the size of the recording material in the other of the cassettes has been found equal to that in the one of the cassettes, the corresponding supply unit is brought into operation to feed the recording material out of the other of the cassettes towards the processing station until the recording material in the other of the cassettes is completely consumed.
