Abstract

PURPOSE:To make size of a cover and regular paper for an inner binding the same by giving a warning when a detected size of a regular size detection means is not matched with a detected size of a cover size detection means. CONSTITUTION:The size of a recording medium for the cover is detected by the cover size detection means 131, the size of the recording medium for inner binding is detected by the regular paper size detection means 1311 to 1313. Then when the detected size by the means 1311 to 1313 is not matched with the detected size of the means 1314, a warning means is energized by a warning control means, and a warning is given to an operator by the warning means/ Thus, when the special paper and the regular paper differ in size, a warning is given beforehand to the operator. The operator exchanges the paper to the special paper or the regular paper of the appropriate size in response to this warning, and image formation is carried out with the same size paper.

Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an image forming apparatus, and relates to an image forming apparatus that sequentially forms images in series on special paper such as %l, - front cover, back cover, etc. and plain paper for saddle stitching. 5. Regarding equipment

[Prior Art] Conventional image recording devices, such as copying machines 1. '', there are multiple types of transfer paper for recording images, each with different sizes. "ing. but,
Recently, not only the size of the transfer paper is different, but also the cover and 1.
A device is provided that has a means for storing special paper for use as a transfer paper, selectively feeds special paper in the same way as transfer paper (plain paper) as needed, and records on the special paper. 1. In such devices, there is usually a dry mode called cover mode.
In this case, special paper is fed only for the first original, only the last original, or both the first original and the last original, and plain paper is fed for the other originals. [Problems to be solved and attempted] How often do you use special paper (14) and plain paper? There are many −2.For this reason, the cover is 1000−2.
When selecting a special paper, the 4 noises of the paper can be easily selected based on the ν′ size of the original and the copying magnification, but when selecting special paper, the size of the A-comb is determined as soon as it is used. It is necessary to load the special paper into the tray for special paper, and if the special paper is loaded into the special paper tray, image formation will be performed immediately regardless of the size of the special paper. There is a high possibility that images will be formed on special paper and low-quality paper with different sizes, and an inappropriate copy set should be submitted in the evening. Both

[, I'm here. The purpose of the present invention is to reduce the possibility of such inappropriate image formation. [Means for solving the problem] Invention IJ of the present application, image forming means (110, 12

Ru. [Operation] According to the invention of j1!1 of the present application, the 1 cover image detection means (13L) detects the size of the recording medium for the cover, and the 24 normal size detection means (13L to 131g> detects the size of the recording medium for saddle stitching). 1114 Detecting the arrogant size 1, Shikashi'1:, normal ()', size detection f stage (DI+-1: (I*) detection size is the cover...Ize detection '1: stage (13N4) When the detection size and the failure are detected, the warning control means (400) activates the warning means (34) (I7), and the warning means (34) issues an operator)2 warning (3,1,!,-). , as mentioned above.) (J) If the size of special paper and plain paper is different and an inappropriate image is formed, this warning will be issued. Depending on the alarm, you can replace it with special paper or plain paper of an appropriate size (images can be formed on special paper and plain paper with the same size.
'Is it possible to form inappropriate images? Y L, , I, the probability of failure decreases. , the second @' invention of the present application +5'', then
The cover size detection means (131,) detects the size of the recording medium for the cover page 15, and the normal ± size detection unit (131,

The photosensitive drum 12 rotates in the clockwise direction shown in the figure, and before receiving the light reflected from the optical system 110, the photosensitive drum 12 is charged in the manner shown by the charger 1221. , a charge-removal υ latent image area is formed by the eraser 123. (2) When this latent image area is irradiated with light reflected from the original, a charging groove is generated depending on the intensity (7), and an electrostatic latent image is formed. This electrostatic latent image is developed. The developer 124 produces a developing image 1, and depending on the density of the original, I 2 ~ is deposited L?'' to form a toker image J. This l 2 ner image i, t, It can be transferred to paper, but in order to make the transfer easier, P
The TL 125 eliminates static electricity before transfer. The recording paper fed out by the registration roller 135 is brought into close contact with the photosensitive surface of the photosensitive drum 121 by the guide mylar + 36, and is placed in the direct position of the transfer charger 126. 3. After this il, the recording paper is separated by a separation channel A.,-
However, if the separation is insufficient at this time, the separation claw 128 forces the separation. After the recording paper is separated, the remaining toner is removed by the photosensitive surface 1, 1 of the photoconductor drum controller 21 in the cleaner 1'2A, and the recording paper is transferred to the conveyor belt 12111Q:,J, and the fixing device 12Ci;

If there is no normal transfer paper (plain paper) in the direction, the setting of cover 9=- for forming the cover is prohibited, and cover-drying-1: is not executed. [Effect of the invention] The first aspect of the present application According to Hikari, when an inappropriate image is formed on special paper for the cover and plain paper for saddle stitching with different glue and size, a warning is sent to the operator in advance. Depending on this alarm, change to special paper or plain paper of appropriate size lMize to the same special paper and plain paper
Image formation can be performed. This reduces the probability of improper image formation and errors. According to the second invention of the present application, when an inappropriate image is formed when the special paper for the cover and the plain paper for saddle stitching 5 are of different sizes, the image formation in the cover formation mode is performed in advance. It is forbidden. This results in improper directional image formation and
It never happens. In the evening of the operation, if the image formation on the cover page has not started, the special paper and the plain paper will be nicked, and the appropriate size of the special paper or the regular set number will be set.
Images can be formed on special paper and regular paper of the same size by replacing them 2.
