Abstract

PURPOSE:To obtain a binding margin having a desired width by providing offset value scale on a manual insertion paper feed tray in a direction orthogonal to a paper feed direction so as to allow copying sheets to be fed being precisely shifted by a predetermined value. CONSTITUTION:In order to feed paper sheets so as to set a desired binding margin with the use of a manual insertion tray 31, first copying sheets are loaded between guides 32, 33 so as to make one side end of the copying sheets abut against an abutting part 32b of the guide 32. In this condition, the position of the guide 32 is adjusted so as to align the edge of offset value scale indicating the size of the desired binding margin on scale 40 formed in a horizontal part 33a of the guide 33, with the one side end of the copying sheets P. At this time it is confirmed that the abutting part 32b of the guide 32 abuts against the one side end of the copying sheets. With this arrangement, a desired offset is given to the copying sheets which is therefore guided thereby, and accordingly, it is possible to obtain a desired image bearing medium.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a manual paper feed tray used when manually feeding copy paper into a copying machine, and in particular, to a manual feed tray used when copy paper is manually fed into a copying machine, and in particular, when copying is performed by shifting the image position with respect to the paper surface. Regarding the manual paper feed tray suitable for

[Conventional technology]

Manual difference. Copying machines equipped with a paper feed mechanism are widely used, but in order to feed copy paper of various sizes to the correct position using manual paper feed, the manual paper feed tray can be adjusted according to the size of the copy paper. The apparatus is provided with a paper feed guide member, and is configured so that the original placed on the original glass is copied onto the copy sheet at the correct position.

[Problem to be solved by the invention]

When copying, there are cases where it is desired to shift the position of the document relative to the surface of the paper and copy, for example when it is desired to provide a binding margin on the side edges of the copy paper. In this case, conventionally, (1) the original is copied once, and then pasted onto a blank sheet of paper in a shifted position to create a second original, which is then copied. (2) Set the original position on the original glass of the copying machine at a different position from the normal position, and make a copy.

(3) Methods have been used, such as using a copying machine with an image editing function and editing the image by shifting its position before copying.

However, method (1) takes time to create the original and uses an extra copy, and method (2) requires the original to be placed face down on the original glass, so the original is shifted by an amount. difficult to confirm.

In addition, method (3) requires the use of a special copying machine, and requires inputting the shift amount, making it difficult to perform simple operations, especially when copying a small number of copies such as one or two copies. It was inefficient.

[Failure to solve the problem]

In order to solve the above problems, the present invention provides a manual paper feed tray installed in a copying machine equipped with a manual paper feed mechanism.
A paper feed guide member having a paper side edge abutting surface parallel to the paper feeding direction, and a paper feed guide member having a paper side edge abutting surface parallel to the paper feeding direction, and a copying paper conveying path in a direction perpendicular to the paper feeding direction with the paper side edge abutting surface of the paper feeding guide member as a reference position. An offset amount scale indicating the amount of deviation is provided on the paper feed guide member.

[For production]

Since the offset amount scale indicates the amount of deviation in the direction perpendicular to the reference line in the feeding direction of the copy paper, the copied image of the original placed at the normal position on the original glass was fed with a deviation. It is possible to record on the copy paper and form a binding margin according to the deviation amount K.
