Abstract

PURPOSE:To copy plural originals to plural copy forms, whose number corresponds to the number of originals, with one copying operation by providing a control part which outputs a control signal, by which plural copy forms are fed one by one on a basis of the operation of sensors, to a paper feeding means when a command which copies plural originals to plural copy forms whose number corresponds to the number of originals is inputted in one copying operation. CONSTITUTION:When a start key 3 is turned on after switches of a form size and number commanding part 5 on a console 6 are turned on to designate the display of a copy number display part 4, a scanning system 8 starts scanning an original 1 by the control of a microcomputer 19. When a sensor 9a senses the light of a light source 8a, a sensor signal is inputted to the microcomputer 19, and the first copy form is supplied from a paper feeding tray 11 to a transfer part 10a of a photosensitive drum 10. A sensor 9b is moved; and when it senses the light of a light source 8b, a sensor signal is inputted to the microcomputer 19, and the second copy form is supplied to the transfer part 10a similarly. Thus, two originals are copied to two copy forms with one copying operation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a control device for a copying machine that allows a plurality of originals to be copied onto a plurality of copy sheets corresponding to the number of originals by one copying operation.

(Prior Art) A conventional copying machine is designed to scan an original once in one copying operation, feed one sheet of copy paper, and make a copy. Therefore, for example, when copying a two-page spread of a book, etc. onto two sheets of copy paper, after copying the first page in the first copying operation, shift the second page of the document onto the scanning surface. If you have to perform a second copying operation, and if copies are made on one sheet of copy paper in a single copying operation, be sure to fold the copy paper or cut it into two sheets when making the original copy. There is a wall (this is 2
The same applies when copying multiple sheets of separate originals at the same time).

For this reason, it takes a long time to make copies, and it takes time and effort to make original copies after shredding copies.

(Objects and Structure of the Present Invention) The present invention has been made with an eye to the above, and is capable of copying multiple manuscripts in a single copying operation in order to speedily perform work or original work after copying. When a command is given to copy on multiple copy sheets according to the
The present invention provides a control device for a copying machine that feeds sheets one by one.

(Example) Hereinafter, a copying machine control device according to the present invention will be described in detail.

FIG. 1 shows an embodiment of the present invention, which shows a platen 2 on which a document 1 is placed, a start key 3, a number-of-copies display section 4, and an instruction to make two copies in one copy operation. A console 6 having a paper size and paper number command section 5, etc.
is provided on the top of the copying machine 7. Inside the copying machine 7, there is a scanning system 8 (light source lamp 8a) that scans the original 1.

Mirrors 8b, 8c*8d + lens mirror 8e) and a light receiving sensor 9a sensitive to the light source lamp 8B
, 9b, and a photosensitive drum 10 exposed by the scanning system 8.
and a paper feed tray 1 that supplies copy paper to the transfer unit 108.
1 is provided. Around the photosensitive drum 10, there is a charging corotron 12, an exposure slit 13, and a photosensitive drum lO.
A developing section 14 that performs development based on the latent image (4), a transfer corotron 15 provided in the transfer section 10a, and a cleaner 1 that removes toner after transfer from the photosensitive drum 10 are also provided. A downstream stage (transport bell) 17 and a fixing section 18 are provided after the transfer section 10a, and a microcomputer 19 for controlling the operation of the copying machine 7 is provided.

The microcomputer 19 includes an input interface 19a for inputting operation command signals from various sensors in the copying machine 7 or the console 6, a ROM 19b for storing programs necessary for processing the beginning of the long sword signal, and a ROM 19b for storing predetermined programs based on the programs. A CPU 19c that performs calculations, a RAM 1gd that temporarily stores calculation results and data, and an output that outputs control signals to various control objects of the copying machine 7 or the display section of the console 6 based on the calculation results. It has an interface 19e.

To explain the operation in the above configuration, after placing the original on the platen 2, turn on the "B5 When the display on the number of sheets display section 4 is designated as "l-1" and the start key 3 is turned on, the scanning system 8 starts scanning the original J under the control of the microcomputer 19. When the sensor 9a is sensitive to the light from the light source 13a, Sensor signal is sent to microcontroller 1
9, the first copy paper is supplied to the paper feed tray 11 and then to the transfer section IQs of the photosensitive drum IO. Next, when the sensor 9h moves and is sensitive to the light from the light source 8b that scans the material, the sensor signal is input to the microcomputer 19, and the second copy paper is placed in the paper feed tray 1J! llll photosensitive flano
(Supplied to the transfer unit 10B of I. In this way, two originals can be copied onto two copy sheets by one copying operation. FIG. 2 shows a flowchart of the operation according to the present invention. In addition to the operations described above, when a sheet of original is placed on the platen 2, a normal copying operation is performed (this is self-explanatory, so the explanation will be omitted).The sensor 9a is omitted in 1-7. It may also be replaced by a signal from the start key 3.

(Effects of the Invention) As explained above, according to the control device for a copying machine according to the present invention, when a plurality of originals are instructed to be copied onto a plurality of copy sheets corresponding to the number of originals in one copying operation, Since a plurality of copy sheets are fed one by one, the time required for close-up photography can be shortened, and preparation of original copies after copying can be performed quickly.
