DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the configuration of FIG. 1 will be described. In FIG. 1, a paper feed mechanism 1 is a mechanism for feeding a standard size sheet of paper, and a moving guide 2 is adjusted so that the width is exactly the size of a standard size sheet, and a plurality of standard size sheets are placed on the printer ( The printer 4 sequentially feeds the sheets one by one and prints them.

The movement guide 2 adjusts the width of the standard paper to be printed and places a plurality of standard papers. The standard paper detection sensor 3 detects which width of the standard paper the width of the paper adjusted by the movement guide 2 corresponds to. For example, the width of a standard paper such as A4, B5, A5, and postcard is automatically detected.

The printer (printing machine) 4 prints on the paper fed one by one from the guide mechanism 5. The guide mechanism 5 according to the present invention is for feeding a non-standard size sheet, and is composed of a guide 51, a fixing mechanism 6, a sheet size fixing guide 7, and the like.

The guide 51 is a guide having a width of a non-standard-size sheet, and a large number of non-standard-size sheets are placed on the guide 51. The fixing mechanism 6 is a mechanism for fixing the guide mechanism 5 to the paper feeding mechanism 1, and here, the guide mechanism 5 has a convex portion, the paper feeding mechanism 1 has a concave portion, and the convex portion is inserted into the concave portion. It is for fixing.

The paper size fixing guide 7 is a guide mechanism 5.
This is a fixed guide having a width corresponding to the length of the non-standard size sheet to be printed, which is the width of the moving guide 2 when the sheet is placed on the sheet feeding mechanism 1. For example, when the length of the non-standard size paper is A4, the width of the paper size fixing guide 7 is equal to the length of the moving guide 2 fixed by the width of A4. As a result, by determining the width of the fixed paper size guide 7, the length of the non-standard size paper placed on the guide 51 and fed is arbitrarily set (for example, A4, B5, A5, and postcard length). It becomes possible.

Next, a specific configuration example of the guide mechanism of the present invention will be described with reference to FIG. This is a perspective view of the guide mechanism 5 of FIG. This is a configuration example of the guide mechanism 5 that sequentially supplies the nonstandard paper having a length of five business cards to the printer 4.

In FIG. 2, the guide mechanism 5 includes a guide 51 having a business card width (about 92 mm), fixing mechanisms 6 and 61,
62 and a paper size fixing guide 7. Here, the guide 51 is the width of a business card (about 92 mm)
With a guide. A plurality of sheets (for example, 100 sheets) are piled up on the guide 51, and one by one a sheet conveying mechanism (not shown) is conveyed to the printer 4 by the computer.

The fixing mechanism 6 is for fixing the guide mechanism 5 to a predetermined position of the paper feeding mechanism 1 in FIG. 1, and here,
The guide mechanism 5 side has a convex portion, and the receiving side paper feeding mechanism 1 has a concave portion, and the convex portion is inserted into the concave portion and aligned and fixed.

The fixing mechanisms 61 and 62 are the paper feeding mechanism 1 of FIG.
It is intended to be fixed by hooking it on. The paper size fixing guide 7 fixes the width of the moving guide 2 shown in FIG. 1 to a predetermined size of a standard size paper. For example, in the case of the above-mentioned paper having a length of five business cards, since the length corresponds to A4, the width of the moving guide 2 is fixed to the width of A4. Determine the width.

When the guide mechanism 5 shown in FIG. 2 having the above-described structure is placed on the paper feed mechanism 1 of FIG. 1 and the moving guide 2 is narrowed so as to contact the fixed paper size guide 7, the guide mechanism 5 is formed. A plurality of sheets of paper (herein, a sheet of FIG. 5A having a length of five business cards, which will be described later) is fed to the printer 4 one by one, and the printer 4 converts the sheets into A4 sheets. In the same manner as printing, printing is performed on the non-standard size paper (five business cards are printed on one paper at a time as shown in FIG. 5B described later).

FIG. 3 shows another block diagram of the present invention. This shows an example in which two sets of the guides 51 of FIG. 1 are provided. By providing two sets of this guide 51, it is possible to feed two sheets of paper at one time.

In FIG. 3, the fixing mechanism 6 is
The two sets of guides 51 are provided at the central portions as shown in the figure and fixed to the paper feed mechanism 1. As a result, the guide mechanism 5 having the two sets of guides 51 can be placed on the paper feed mechanism 1 to feed two non-standard size papers to the printer 4 at a time.

FIG. 4 shows another block diagram of the present invention. In this, the engaging portion 81 is fixed on the sheet feeding mechanism 1 of FIG. 1 by the fixing mechanism 6, and the engaging portion 82 at the bottom of the guide mechanism 5 is placed at an arbitrary position on the fixed engaging portion 81. It is a thing.

In FIG. 4, a meshing portion 81 is formed by inserting a convex portion of the fixing mechanism 6 into a concave portion of the sheet feeding mechanism 1 and fixing it, and meshing the bottom portion of the guide mechanism 5 at an arbitrary position above this. It is for arranging the part 82.

The engaging section 82 is provided on the bottom of the guide mechanism 5, is placed on the engaging section 81 fixed to the sheet feeding mechanism 1, and fixes the guide mechanism 5 at an arbitrary position.

The position specifying pin 9 is used for detecting the position of the guide mechanism 5 by the position detecting sensor 10. The position detection sensor 10 detects the position of the position designation pin 9 attached to the guide mechanism 5. Based on the position of the position designating pin 9 detected by the position detection sensor 10, the print position in the width direction for the paper placed at the position sandwiched by the guides 51 of the guide mechanism 5 is determined.
Therefore, the guide mechanism 5 having the engaging portion 82 on the bottom portion
Is placed on the feeding mechanism 1 at an arbitrary position of the meshing portion 81 fixed by the fixing mechanism 6, the position detecting sensor 10 detects the position of the position specifying pin 9, and characters or the like are printed on the paper based on this position. Print. As a result, even if the position where the guide mechanism 5 is placed on the interlocking portion 81 is changed, the guide mechanism 5 is changed.
A computer system (not shown) controls the position in the width direction of the paper so that the same characters and the like are printed on the paper fed from the printer, and the use position of the photosensitive drum surface is set to an arbitrary position. It can be changed easily.

FIG. 5 shows an example of the paper of the present invention. FIG. 5A shows an example of paper (before printing). This is a case in which five sheets of business cards are used as one sheet and printing is performed on this sheet at one time. This business card printing paper is 91 x 29
It has a size of 7 mm, has a length of A4 paper, and has a very small width of 91 mm. Therefore, the width of the guide 51 of the guide mechanism 5 of FIG.
m, and the width of the paper size fixed guide 7 is the movement guide 2
The size is such that the width of is equal to the width of A4.

FIG. 5B shows an example of paper (after printing). This is an example in which five sheets of business cards are used as one sheet and the sheet of FIG. 5A is printed once with the configuration of FIG. Here, five business cards are printed at once as shown in the figure, so this is cut into five business cards.
