Description

[Detailed description of the invention] The present invention uses a copy size display device in a copying machine, more specifically, in a copying machine that can change the paper size or copying magnification, by setting the paper or copying magnification, This invention relates to a copy size display device that can display the size and location around a platen (original table).

In conventional copying machines, if there is only one type of paper feed tray, the size of the loaded paper, or if there are two or more types of paper feed trays, the paper stored in the selected paper feed tray. The size of the copy machine was displayed in text on the console located a little away from the platen of the copier, and when the copy magnification was changed, it was displayed only by the on/off status of the copy magnification conversion knob, so the size of the paper or After checking the copy magnification, the original was placed on the platen according to the mark marked on the outer edge of the platen and copied, so the correspondence between the paper size or the copy magnification and the original size was unclear, and the paper size Alternatively, it is difficult to copy the original according to the copying magnification, or the original is placed in the wrong place, making it difficult to accurately place the original on the platen.

This invention was developed in view of the above circumstances, and is a copy size display that allows the operator to directly visually inform the operator of the size of the paper set in the copy machine or the range of originals that can be copied onto transfer paper. The aim is to provide equipment.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a schematic diagram of a copying machine, in which 1 is an exposure lamp and 2 is a platen. 4, 5 and a light amount adjustment slit 6, the light reaches the photoconductor 7 and is exposed imagewise to form an electrostatic latent image, which is developed by a developing device 8 and becomes a toner image. , the toner image is transferred from the paper supply device 9 to the paper sent out by the feed roller 10, the toner image is fixed on the paper to which the toner image is transferred by the fixing device 11, and the paper receiver is fed to the device 12. It is similar to that.

In FIG. 1, reference numeral 13 indicates a copying operation panel having a copying magnification conversion knob 14, etc., and 15 indicates a toner cleaning device.

FIG. 2 and subsequent figures show a copy size display device according to the present invention used in the above-mentioned copying machine. - A mark portion 18 indicating the position to be exposed to light as the transfer sheet is transported, on the registration guide 17 provided in an L shape and protruding toward the L direction. , 182゜183...... are provided through them like a thank-you note, and below these mark portions 18□, 182, 183 are provided.
Lamp 19 that irradiates ...... from below. ．． 19□
, 193... are provided.

The above-mentioned mark portions 180, 182, 183, .
For the size, turn on the lamps 192 and 194 and mark 18.
2,184 to display the division.

Similarly, when the size is 84, as indicated by the two-dot chain line in the figure, the lamps 19□ and 195 are turned on, and the mark 18.
, 18. 85, which is indicated by a dashed line and is indicated by a dashed line.
For size, the lamps 193, 19. Turn on the mark 183
, 185.

The lighting of each of the above-mentioned lamps is controlled by a control device, and the corresponding lamps are turned on depending on the size of paper to be set or the copying magnification.

Each of the above landmarks 18. ．． 18°, 183... is the third
As shown in the figure, if a transparent or colored plate 20 is fitted into the through hole, the display effect will be enhanced.

In addition, as shown in Figure 4, a small lamp (LED etc.) 21
may also be embedded in the Regis I ration guide 17.

On the other hand, display characters 22 may be printed or engraved on each mark.

Furthermore, FIG. 5 shows another embodiment, in which a transparent plate 23 for displaying copy size is embedded in the registration guide 17, and is illuminated from below with a lamp to make the characters stand out.

Since the present invention is as described above, copying failures due to mismatch between paper size or copying magnification and document size are eliminated.

In addition, the transfer range can be clearly defined even during reduced copying, and it can be displayed at a low cost.

Furthermore, the display on the console can be omitted, resulting in a considerable cost reduction, especially when only small lamps such as LEDs are used.

Furthermore, since the document setting position is displayed with light, registration is easier than with conventional systems.

In addition to each of the above effects, A4. In most cases, the general public cannot tell the difference between sizes such as B4, etc., but according to the present invention, even such people can be directly informed of the clear copy size. Confusion during copying or copying errors can be eliminated.

Particularly, according to the present invention, the registration guide 17 includes a plurality of marks 18□, 18. , , .
2. A lamp 19 for selectively lighting up and displaying a predetermined mark corresponding to the size of the copy paper and the copying magnification near the . ．． By providing 19□, . . ., the mark displayed when the lamp is lit will not be obscured by the original, no matter what orientation the original is placed on the platen glass 16. Therefore, there is no need to lift up each document and align the document, and the document on the platen glass 16 can be aligned very easily by simply aligning the document with the registration guide 17.
