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 lighting device in which an amount of light emitted by a lamp is detected by a light receiving element for controlling the input voltage of the lamp commensurate with the detected amount of light. By utilizing a pre-illumination system in conjunction with the lighting device, it is possible to improve the sensitivity characteristics of the light receiving element as the lamp is being charged up to a desired level of illuminescence and to prevent the input of an excessive voltage to the lamp.

A mechanism for withdrawing and cutting sheet from a storage roll thereof to predetermined lengths includes a feed roll driven by a clutch transferrable between engage and disengage conditions and a shaft rotatable single cycle cutting blade located forward of the feed roll. The shaft is spring biased in a blade sheet cutting forward direction and means are provided for loading the spring following its unloading. The shaft is releasably locked in a blade retracted position and is releasable by a first solenoid to effect a cutting cycle and a timing member rotatable with the shaft acts through a motion transmission to disengage the clutch and releasably lock it in disengage position at least during the cutting of the sheet. Following the cutting cycle, the clutch may be actuated to its engage position by the energization of a second solenoid. Alternatively, the clutch may be fully controlled by the second solenoid by a circuit network responsive to the positions of the timing member.

Presetting counter device for control of single or repeated actuation of a piece of equipment permits stopping of equipment action during continuous repeat action thereof if required, and always resets a display means for an indication of the number of times the device is required to be actuated to "1" when the equipment is thus stopped and after single or repeated actuation of the equipment, whereby manual resetting action by a user is unnecessary. As the device requires manual actuation only of a resetting switch, an initial count means for specifying a required number of actions during actuation of the equipment, and a start switch, equipment control with the device is extremely simple.

In an electric safety switch circuit for use in apparatus having at least one safety switch for detecting at least one abnormal condition of the apparatus, switching elements are connected between a power source and the apparatus. The voltage of the main power source is transformed to a lower voltage and the switching elements are opened or closed by control circuitry in the low voltage circuit. The at least one safety switch is connected to the voltage transformer and the control circuitry such that the actuation of the at least one safety switch upon detection thereof of an abnormal condition actuates the control circuitry to open the switching elements and disconnect the apparatus from the power source.In one embodiment a primary switch is interconnected between the power source and the electric safety switch circuit, and in a modified embodiment the primary switch is connected in the electric safety switch circuit itself. The reduction in the voltage and current in which the primary switch and/or the at least one safety switch are interconnected results in improved reliability, durability, and operating life of the electric circuit as well as providing commensurate decreases in the cost of the electric circuit.

An image editing system which comprises a memory device capable of storing editing data in memory, copying device to perform edited-image copying based on data stored in the memory device which is attached to the copying device, and an input device, which is separate from the copying device, for entering edited data in the memory device.
摘要:
An integral document processing apparatus comprising an electrophotographic copying system and a facsimile transmission system. A document fed from a common document storing unit is guided selectively to a first document read unit included in the electrophotographic copying system or to a second document read unit included in the facsimile transmission system by a document feed passage changeover mechanism which is operated selectively by an operator. A document delivered to the first document read unit is copied by the electrophotographic copying system. A document delivered to the second document read unit is converted into a corresponding electric image signal, and then the electric image signal is applied to a communications line.
摘要:
A copier including a detector for detecting malfunctions in the copier or nonoperative conditions of the copier; and a system for storing voice signals corresponding to the detected malfunctions and nonoperative conditions and a voice producer for producing a voice corresponding to each of the stored voice signals. When an operator attempts to operate the copier, a voice is produced to inform the operator of the malfunction or nonoperative condition of the copier. Voice is produced only when manual-starting or door-opening is sensed.
