Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image forming apparatus that has an improved magnification display means that indicates the magnification of an image relative to a document.

(Prior Art) Many of the recent image forming apparatuses, such as electronic copying machines, are equipped with a variable magnification means that can appropriately select and change the size of an image relative to a document. This is done by operating the first input stage and display means provided in the variable magnification setting section. There are also two types of dual magnification, for example, a standard magnification means that enlarges the image of an A4 document to A3 or reduces it to B5 to form both images, and There are continuous magnification means called zoom magnification changing means for enlarging and reducing, and at least one of them is provided.

11. The magnification setting section is provided with a constant magnification input means for the constant magnification fΔ and a step for displaying the constant magnification, and also one step for inputting a magnification rate and a magnification rate for continuous magnification. Display means are provided.

In the case of fixed-form magnification, a fixed-form magnification input means and a key are provided.For example, each time the key is pressed, the variable magnification item is specified and the sections are lit up in sequence 71. It has become.

On the other hand, in the -C1 continuous variable magnification means, input of the variable magnification and display of the variable magnification are performed, so for example, the variable magnification input means and 17 are three keys for enlargement, same magnification, and reduction.

Each time a key is pressed, numbers such as 101%, 1.0296, etc. are sequentially displayed on a window frame provided close to this, and a digital variable magnification display means is configured. has been done.

Among the display methods listed above, fixed-size variable magnification types are said to pose no operational problems, but the variable magnification rate is generally not displayed and is often displayed on a paper chair, making it difficult to understand the variable magnification rate. There are drawbacks that are difficult to overcome.

Also, with continuous variable magnification, the variable magnification ratio is displayed numerically, so it is easy to judge it intuitively and misread it.
In addition, the display changes at high speed by pressing and holding the J key for 1 step, but it is necessary to input carefully before and after the desired magnification ratio. There are disadvantages such as requiring it.

(Problem to be Solved by the Invention) As mentioned above, the fixed magnification display means with 1' steps of fixed magnification has the disadvantage that it is difficult to grasp the magnification ratio because it displays the paper size, and the magnification ratio of the continuous magnification means is difficult to grasp. The display is a numerical digital display, which makes it difficult to grasp the paper size, and it is also possible to make a mistake when reading the magnification ratio, which takes time to set, resulting in low efficiency and waste of paper. If there are many cases, it is inconvenient.

The present invention has been made in order to eliminate the above-mentioned disadvantages. 1. It is easy to read, the desired magnification ratio can be set without any errors, and the magnification ratio is not displayed at a fixed magnification ratio of 7 steps. It is an object of the present invention to provide an image forming apparatus which also has one stage for displaying a magnification ratio so that the mutual relationship between the two continuous magnification ratios can be easily understood.

In each of the above embodiments, the specific magnification display means is explained using a fixed magnification as an example, but it is not limited to this, and it is of course possible to apply it to other specific magnifications. . Further, the light emitting body is not limited to I, G; ■), and may be lit or blinking.

[]Effect of fixed light W" As detailed above (2. It is easy to read intuitively, there are fewer mistakes when reading, and work efficiency is high.In addition, the wasted use of paper due to incorrect settings is greatly reduced. With this display, you can easily understand the relationship between the C1 and C1 displays (in conjunction with the light emitting), and you can reliably, quickly, and appropriately set the magnification ratio.
