Abstract

PURPOSE:To form automatically a space part for the binding margin in the side of punched holes, by detecting punched holes formed in the side of the space for the binding margin of a sheet and adjusting the quantity of sheet feed on a basis of this detection. CONSTITUTION:A toner image on a photosensitive drum 6 is transferred to a transfer paper, which is fed from a cassette 7 into a carrying path 11, in a transfer station 14, and the transfer paper is sent into a sheet inverting device 17 through a fixing equipment 16. A sensor 12 where plural photosensor groups are arranged in the direction of depth is provided in the transfer paper carrying path 11, and it is detected whether punched holes are formed on the transfer paper or not and positions of the transfer paper where these punched holes exist are detected to generate a signal, and register rollers 13 are controlled on a basis of this signal to adjust the feed timing. Consequently, a space part for the binding margin is automatically formed in the side of punched holes without errors even in a double-face copying machine or the like.

Description

[Detailed Description of the Invention] The present invention provides copying machines, printing machines, recording machines, and other sheets*
41, regarding binding margin forming devices for 5m machines, etc. (hereinafter simply referred to as copying machines, etc.), in particular, binding margin forming devices for copying machines, etc. that are capable of automatically forming a binding margin on the white side of the edge of the sheet. The present invention relates to a forming device.

Conventionally, in this type of device, the operator preliminarily commands the binding margin, and the edge margin margin is formed on the designated side.

Therefore, for example, in double-sided copying, etc. ii.If one foot is added or if the standard alignment of the document placed on the document table is checked, the result will be the same margin or the opposite in the ll'il direction of the sheet. Yes, it was very inconvenient.

Therefore, the object of the present study is to provide a standard margin forming device for copying machines, etc., which is improved in view of these points.

No. 511 object of the present invention is to provide a binding margin forming device for a copying machine, etc., which detects the binding margin white side of a company sheet in advance and automatically forms a binding margin on the bell. .

Still another object of the present invention is to detect the opening of a punch hole in a sheet and form a binding margin in-house. ! It is an object of the present invention to provide a device for forming a rut for a temple.

An advantageous configuration of the present invention that can achieve the above object is a binding margin forming device such as a copying machine that forms an image by forming a binding margin white area on a sheet. This is a binding margin forming device for a photographic machine, etc., characterized in that it is configured to detect an opening and automatically form a white binding margin on the side where the opening is formed.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the drawings.

The photosensitive drum 6 rotates in the direction of arrow B at a circumferential speed synchronized with the scanning of the first roller 2, and the toner is exposed to light through the electrostatic photographic process arranged around the photosensitive drum 6. formed on the drum. On the other hand, the transfer paper is sent out into the conveyance path: 11 by selectively driving the paper feed row 2:9.10 from the cassette=7 or the deck=8. At this time, a group of multiple photosensors arranged in the execution direction in the figure: 12

It is guided to the intermediate tray 22 and temporarily stored. After the document is replaced, the documents are sent one by one to the refeed bus 24 by the paper feeder 223, and bunch hole detection is performed again.

Thereafter, the process #i is exactly the same as the first copy, in which the copy #i is sent to the transfer station 14 at the correct timing by the register roller 16. After that, the SW reverses and the paper exits from the paper discharge port 25 to be sent to the sorter. Alternatively, the sheets are directly loaded onto the non-sort tray 26 formed at the upper part of the sheet reversing device 17 using the hook par 818. Also, if you want to perform variable magnification and duplication, change the optical path length to R.
The lens position is changed according to Wt*, and the second mirror 3, in-mirror lens 4, etc. are changed accordingly as shown in the figure, and the scanning speed of the first mirror 2 and the rotational circumferential speed of the photosensitive drum 6 are adjusted to the variable magnification ratio. The scanning speed is changed so that the ratio becomes the same. Next, control of the position of the photosensor group 12, the register roller 13 1IIJIi 41, and the lens in the depth direction in the figure will be explained. When a punch hole 27 is placed on one side of the transfer paper as shown in FIGS. 21 and 6, when the sheet is conveyed in the direction of the arrow, for example, as shown in the A group of photosensors 12 shown in FIG. . In addition, if there is a punch hole at the rear end of the transfer paper in the feeding direction (as shown in BL of 2nd (IAs) Lull in Figure 2) (a photo sensor PS1/Pan)
released No. 16, which detected a punch hole in the sharp spot on the transfer paper. Furthermore, if the punch holes are lined up in the paper feed direction as shown in Figure 146, any one of the photosensor groups 12
9P8m reports the detection of the punch hole 27 one after another to η Kusu m as shown in Figure 5 Baa) Only the transfer paper is detected.By determining the position of this PSm, it is possible to determine which side of the transfer paper the punch hole is located on.

When one sheet of paper is placed on the tip axis in the feeding direction, the timing of sending the sheet to the transfer station 14 by the register roller 16 is a little earlier, and the punch hole group is used as a margin to make it look like a t#@tube copy. Conversely, if a punch hole is detected on the back of the transfer paper, register roller 1
By delaying the timing of feeding to the transfer station by 6, the information is not applied to the four punch holes.
1blJ I41. If the punch holes are lined up in the paper feed direction, the lens position can be moved to the opposite side of the punch hole as shown in Figure 6 (the punch hole can be made into a blank space). The Copy+1 shown in this embodiment also has a variable magnification function, so that by changing the registration or moving the lens, it is possible to prevent the original information from being stored on the transfer paper. When creating a binding margin for printing, it is also possible to reduce the size of the manuscript a little so that all of the manuscript information is placed on the transfer paper. Any binding margin forming method may be used, such as Fi-element-based scanning start timing or movement of mirrors, etc., to form the binding margin. Even in the case of 1st page, the operator can automatically form the binding price white part on the same side of the sheet without making any mistake on the 111th and second sides.
