Abstract

PURPOSE:To facilitate the setting of a required magnification by setting the number of copying sheets and a copying magnification by the use of a common numeral inputting means, and providing a switching means which switches to one of them. CONSTITUTION:As the mode setting means, a consol panel 60 is provided with a copying key A which instructs this device to start copying, with a ten-key B, as the numeral inputting means, which sets the number of copying sheets and a copying magnification, and with a clear/stop key C which clears the set value of the number of copying sheets or stops the copying operation. Further, this consol panel is provided with a magnification display key D, as the switching means, which switches the display from the number of copying sheets to a copying magnification, with a copying-magification increasing/reducing key E which increases or reduces the present copying magnification, and with a fixed-copying-magnification key F which sets the specific copying- magnification. In this case, after the numeral of a requested magnification is inputted by the use of the numeral inputting means B, the switching means D switches to the setting of the copying magnification. Thus, the required copying-magnification can be easily set with satisfactory operability.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image forming apparatus having a setting means for setting the number of copies and copy magnification.

(Prior Art) Image forming apparatuses such as electronic copying machines are provided with setting means for setting the number of copies and copy magnification.

Conventional copy magnification setting means includes a fixed copy magnification key that selects a plurality of pre-specified fixed magnifications, and a copy magnification adjustment key that further enlarges or reduces the fixed magnification selected by the fixed copy magnification key. It had become.

For example, if a fixed magnification key of 82% is provided and you want to select 80% magnification, first select 82% with the fixed magnification key, and then press the copy magnification adjustment key to decrease the magnification by 1%. Yuki had set it at 80%.

(Problem to be Solved by the Invention) However, according to the conventional magnification setting means as described above, after selecting a fixed magnification set in advance, the magnification must be adjusted to set the desired magnification. There was a problem that it was troublesome.

The present invention has been made in view of the above points, and an object of the present invention is to provide an image forming apparatus that can easily set a desired copying magnification with good operability.

In FIG. 2, an image forming process configuration means 50, which will be described later, is built into the main body 1 of the apparatus, and an original table 2 made of transparent glass is provided on the upper surface. Also, manuscript table 2
A document holding cover 3 is provided on the top, one end of which is rotatably supported to hold down the document, and an operation panel 60 is provided at the front edge of the top surface of the main body 1.

A front cover 4 that can be opened and closed is provided on the front of the main body 1, and a paper feed cassette 5 containing copy paper P to be supplied to the image forming process configuration means 50 is removably provided at the bottom of the front. . A paper discharge tray 6 is provided on the left side of the main body 1 in the figure to collect copy sheets P on which copying has been completed.

In FIG. 3, the operation panel 60 includes a copy key A for instructing to start copying as a mode setting means, a numeric keypad B as a numerical input means for setting the number of copies and copy magnification;
Clear/stop key C1 for clearing the set value of the number of copies or stopping the copying operation Magnification display key D serving as a switching means for changing from displaying the number of copies to copying magnification display
1 A copy magnification adjustment key E1 for increasing or decreasing the copy magnification from the current state; a fixed copy magnification key F1 for setting a certain copy magnification; an exposure amount setter G for setting the exposure amount. Further, a liquid crystal display section H is provided as a display means for displaying the operating status of each section, the number of copies, copy magnification, etc.

FIG. 4 shows an outline of the image forming process configuration means 50.

Inside the main body 1, there are an exposure lamp 7 and mirrors 8, 9, 10 that move back and forth in the direction of arrow a along the lower surface of the document table 2.
a photoreceptor drum 13 that forms an image of the light reflected by the exposure scanning of the optical system through a variable magnification lens block 11 and a mirror 12; and an electrostatic latent image formed on the surface of the photoreceptor drum 13. A developing device 14, which attaches toner to make a visible image, and a delivery roller mechanism 15 or 16 and a guide path, synchronize with the rotation of the photosensitive drum 13 as shown by the arrow C, and transfer the copy paper P stored in the cassette 5. 17 or 18 to a transfer charger 20 and a peeling charger 21, and a resist roller pair 22 that brings the toner image into close contact with the surface of the photoreceptor drum 13, and transfers the toner image via the transfer charger 20, and a peeling charger. A conveyor belt 23 that conveys the copy paper P separated from the drum 13 by the charger 21;
A fixing roller pair 24 is provided at the end of the copy paper P to fix the toner image onto the copy paper P, and a paper discharge roller pair 25 is provided adjacent to the fixing roller pair 24.The copy paper P passes through the roller pair 25. It is discharged onto the tray 6.

Further, on the peripheral edge of the photoreceptor drum 13, a charger 26 for removing electricity is provided along the rotational direction to remove electricity from the drum 13 after transfer.
A cleaner 27 removes the toner adhering to the surface of the drum 13 after static electricity has been removed, a static elimination lamp 28 erases the residual image on the drum 13, and the surface of the photosensitive drum 13 is charged to form an electrostatic latent image during exposure. Charger 2 for imaging
9 is placed.

Furthermore, inside the main body 1, there is a cooling ring 30 for preventing temperature rise, and a cassette size detector 31, which is located at the insertion tip of the cassette 5 and consists of a plurality of microswitch groups for detecting the cassette size. 32 etc. are provided.

In FIG. 1, various operation keys A provided on the operation panel 60,
The function of displaying the mode set by B, C, D, E, F, and G on the liquid crystal display section H is shown as a block diagram. Mode setting signals issued from various operation keys provided on the operation panel 60 are input to the CPU 60, which is a control means.

The CPU 60 controls the operation of each part of the copying machine based on input signals, and at the same time displays a liquid crystal display H that displays the number of copies and magnification via a display driver 70 and a liquid crystal display (not shown) that displays other modes. This is displayed on the display section 80.

Further, when a number is input using the numeric keypad B, the CPU 60 sets this number as the copy magnification when the magnification display key D is pressed, and sets this number as the number of copies when the magnification display key D is not pressed. It has the function of setting each mode and displaying information on the liquid crystal display section H.

For example, to copy 10 images with a copy magnification of 90%, first enter r9J rOJ using numeric keypad B, then press magnification display key D to set 90%, and then enter rlJ rOJ using numeric keypad B. By pressing the copy key A, the desired image can be copied.

According to this embodiment, when setting a desired magnification, there is no need to combine the fixed copy magnification key F and the copy magnification adjustment key E, and the operability is improved.

〔Effect of the invention〕

As explained above, according to the present invention, the number of copies and the copy magnification are set using a common numerical input means, and a switching means for switching to either one is provided, so that the desired magnification can be easily set. I can do it.
