Abstract

PURPOSE:To execute copying with a simple operation by constituting a magnification memory of a 1st memory for fixed magnification and 2nd memory for the magnification used in the previous time or the arbitrary magnification inputted thereto except unmagnification and reading out the stored contents in order of the 2nd and 1st memory by a call key. CONSTITUTION:The arbitrary magnification is stored into the area M2-2 of the memory M2 according to the enlargement and reduction magnifications, respectively, when an operator pushes a copy key 2 after pushing a mode setting key 1 and inputting the arbitrary magnification by numeric keys 3. The machine is set in a copying mode unless the key 1 is pushed. The number of copies is determined by the keys 3 and the copying is started by the key 2. The enlargement and reduction magnifications of M1, M2 are called out by call keys 5, 6 and are stored in M3. The magnification is M3 changes over to the ensuing magnifications at every all. The call is cyclically executed in order of M2-1, M2-2 and fixed magnification M1. The content of a set magnification area M4 is saved in M2-1 and thereafter, the magnification to be copied is stored in M4 and the copying is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Al Industrial Field of Application) The present invention relates to a copying machine that can form enlarged or reduced copied images according to a set magnification.

(b) Conventional technology In a copying machine that can form enlarged/reduced images, the enlargement magnification (115χ) of B5→A4, A4→B
The enlargement or reduction ratio from a specified size to a specified size, such as the enlargement ratio of 4 (122χ), is stored as a fixed magnification, and the operation of the enlargement or reduction ratio call key provided on the copying machine body is performed. This makes it possible to sequentially recall and set the fixed magnification for each operation. Additionally, a zoom key is provided to finely adjust the magnification by increasing or decreasing the magnification in 1% increments, and the magnification can also be set by operating the zoom key. Copying is then performed according to the set magnification.

In addition, commonly used copying machines have a fixed mode (for example, magnification: 100x1, 71 sheets, etc.), and when a predetermined time elapses without copying, the magnification becomes 9.
The number of sheets etc. are set in the constant mode.

In addition, an equal magnification key for setting the equal magnification ratio is individually provided, and the equal magnification ratio is set by operating the equal magnification key.

Problems to be Solved by the Stomach Invention However, in the past, when copying at a fixed magnification, it was possible to easily set the magnification by operating a call key, but when copying at an arbitrary magnification other than the fixed magnification, teeth,
After calling up a fixed magnification close to that magnification, I had to gradually change the magnification using the zoom key, which was very tedious. In particular, if the number of copies made at a given magnification exceeds the number of copies made at a fixed magnification due to reasons such as creating a file at a fixed size, the user will have to set the magnification using the zoom key each time he or she copies at a given magnification. It was both annoying and a waste of time.

In addition, with copy machines where the magnification etc. are cleared after a certain period of time has passed without any copying process being performed, even if you operate the zoom key and set the desired magnification, the magnification will be cleared while you leave your seat. Sometimes, I had to reset the desired magnification using the zoom key.

This invention memorizes the previously used magnification other than the same magnification or any magnification input by key, and allows that magnification to be recalled preferentially, allowing the magnification to be easily set with fewer operations. The purpose is to provide a copying machine that can.

Means for Solving the FD1 Problem The present invention includes a magnification storage memory for storing a copy magnification and a magnification recall key, and sets the magnification stored in the magnification storage memory by sequentially recalling each time the magnification recall key is operated. In a copying machine that copies according to a set magnification, the magnification storage memory is divided into a first memory that stores a predetermined fixed magnification, and a previously used magnification other than the same magnification or a key input. and a second memory for storing an arbitrary magnification, and further includes means for sequentially calling the stored contents of the second memory and the first memory when the magnification calling key is operated.

(e) Effects In the copying machine of the present invention, the previously used magnification other than the same magnification can be stored in the second memory. Further, any frequently used magnification can also be stored in the second memory. These magnifications are sequentially called up each time a simple operation of the magnification call key is repeated, and copying is performed at that magnification. Further, the previous magnification or arbitrary magnification stored in the second memory is recalled with priority over the fixed magnification and is recalled with fewer operations. The setting of the same magnification is usually easier than using the same magnification key. (f) Embodiment FIG. 3 is a plan view of the operation panel of a copying machine according to an embodiment of the present invention. The operation panel displays mode setting key 1 for switching between copy mode and magnification storage mode, copy key 2 for copy start and storage of magnification, numeric keypad 3 for specifying the number of copies and storage magnification, and input values from numeric keypad 3.
