Abstract

PURPOSE:To set and call new copy magnification data without increasing the number of keys used for calling preset magnification data, by providing each key of a numerical value input means with the data storing function and the data calling function. CONSTITUTION:Numerical value data are set to prescribed magnification keys by the processing of a copy magnification set routine, and numerical value data corresponding to these magnification keys are called by the processing of a copy magnification select routine. When a mode store key 97 and a prescribed ten key are depressed in this state, copy magnification data is stored in a memory corresponding to this ten key together with the other mode data. Consequently, even if original magnification data is erased or changed thereafter, magnification data is set to this ten key as it is. Individual ten keys can have specific magnification data respectively. When one of ten keys 61-70 is depressed while depressing a copy mode load key 98, stored data is loaded.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to variable magnification, 1141. 'One night on the fυ photographic device]
Furthermore, the 88th machine relates to a variable magnification and a copy>li position in which any numerical value within a predetermined 1.11 range of a predetermined number of digits can be stored and a copying operation can be performed using that numerical value as a magnification.

■Next technology allows f%+photography to be performed with multiple magnifications;
, ij devices have been proposed for 4111 or (Vf). However, the conventional hj
Since the 42° position for the M photo was only available for selecting an appropriate magnification from predetermined magnifications for the number of shots7), it is possible to use an intermediate magnification for the first time or setting. It was often inconvenient to make small adjustments to the magnification, such as increasing or decreasing the magnification.

Considering these points, the example is 15-06 9・i
4, and the magnification can be changed steplessly at the level of I/1000, or (1, -
One of the expected drawbacks of this second-generation copying machine is that when copying at a desired copy magnification, the user must set the copy magnification each time, which is cumbersome to operate. be done. For this reason, the same size, A4→
B5, 1% 4 → B5, the commonly used copying magnification or the copying magnification that is likely to be used frequently by the user is preset in the storage device, and this magnification can be called as appropriate.・Is it possible to make it possible to perform a multiple ζ′ operation by using the ζ′ function?
~“・There was a limit to the number of operation keys, so not all users could set the necessary discard magnification, and there was an inconvenience that the continuously variable magnification function could not be used effectively. .

Purpose The present invention has been made in view of the above points, and is intended to be used to input numbers using a numeric keypad or the like. Each key in the row has the function of storing data such as 9n ear multiplication〉Ki, and the function of recalling that data as necessary. Set new copy magnification data without adding the number of keys for data recall,
The object of the present invention is to provide an initial position of an Ef variable magnification type that can be extended.

Examples of the invention and examples are shown in the drawings.

The paper is fed into the machine by the paper feeder Coffin 1 in the paper feeder Coffin 1 (300), which has two upper and lower cassette loading sections installed in the machine, and the timing crawler (21)
, after being stopped, the toner image is sent to the transfer section in synchronization with the image formed on the photoreceptor drum 1ll-L, the toner image is transferred by the transfer charger (7), and the toner image is transferred to the separation charger (8).
), the image is divided from the surface of the photoreceptor drum (1) and sent to a fixing device (23) by a conveyor belt (22), where the image is fixed and ejected onto a tray (24). After the photosensitive drum (1) has been transferred, the toner and electric core remaining on its surface are removed by a cleaning device (9), an eraser (2), etc., and the photosensitive drum (1) is used for the next two copies.

In the case of automatic paper feeding, the image forming system including the photosensitive drum (1) is started by operating the print key (1) SW) (see Figure 4) that starts the copying operation of the copying device (100), and the photosensitive drum (1) is started. When the pre-driving process for the body drum (1) is completed, the paper feed roller (25) or (26) or the paper feed roller (301) of the paper feed unit (300) or (
302), and the scanning optical system (10) is driven by a scan start signal output as the copy paper is conveyed.The copy paper is fed in synchronization with the image forming operation.

In the "Auto paper selection" mode, the copy magnification is fixed and +l
This mode determines the optimal paper size based on the size of the original and its magnification, automatically selects the paper source, and feeds copy paper from the selected paper source. .

In the "Automatic magnification selection" mode, the size of the copy paper to be used is fixed, the corresponding copy magnification is calculated from the size of the original document and the copy paper size, and the magnification setting mechanism described later is used. This is a mode in which copying operations are performed by automatically setting the copying magnification.

I) There are 1. near the original insertion slot of the I unit (202).
The document length sensor (Slit) is positioned so that the document can be detected regardless of the size and orientation of the document. A document width sensor (SF, 2) is provided, and the size and orientation of Bit f+2+ are identified by signals from these two sensors.

Various methods have been proposed for identifying the size of 111 sheets of paper. The document length sensor (5(,1)) measures the detection time, while the document width sensor (Sli2) determines whether or not it has detected the document, and both signals are used to measure the detection time. We use a method that determines the size and orientation of the original.In our method, if I+7 is a manuscript or a standard paper size, it is possible to identify most sizes just by using the length signal.
For the 4-column and 13-column paper sizes adopted in Japan, the length signal is determined depending on the length and width of the g5. To do this, a document width sensor (SL, 2) is provided.

It is considered that the copying operation can be executed based on the preset values.Therefore, the preset copying machine is often used, for example, when the destination is [1] at the factory delivery stage. A magnification that is considered to be the same is selected.This will be discussed later.

In this way, the first set of keys 71 allows the user to arbitrarily set the required copying magnification, and the second set of keys is generally used.

For example, for domestic use, A/I → Is 5, Is

However, since the number 1 white preset in the second key Ji'1 is the general or W'l place -1- copying magnification, there may be mechanical error or design error. The actual copy size may differ slightly depending on the size and size of the copy. Even if you select the same size (x1),
