Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image forming apparatus such as a copying machine that illuminates an original image with an illumination means and obtains a copy of the illuminated image.

[Prior Art] Conventionally, as an example of this type of device, a reader printer is known, which enlarges and projects an image on a microfilm onto a screen, and prints a copy image on copy paper when necessary. Copy images copied by this reader printer are ejected from inside the device onto a paper ejection tray, and it is desirable to be able to check the image quality and other conditions of the copy images on the copy sheets stacked on the paper ejection tray. However, when the paper ejection tray is placed at the bottom of the apparatus, it becomes dark because it shadows the apparatus and the operator, making it difficult to confirm the copied image. In particular, if a portion of the paper ejection tray is placed inside the device, it will be even darker, making it difficult to confirm. Also, in the case of a reader printer, because you want to see the screen image clearly,
There are cases where they are used in dimly lit places, and this problem is more serious than in copying machines that use reflective originals such as documents.

[Objective] The present invention aims to solve the above-mentioned conventional problems, and provides an image forming apparatus that can easily check the quality of a copied image even in a dark environment.

[Means for Solving the Problems] The present invention is characterized in that a portion of the illumination light generated from the illumination means for illuminating the original image illuminates the copy sheet storage section.

[Embodiment] FIG. 1 is a longitudinal sectional view of a reader printer showing one embodiment of the present invention. 1 is the main body frame, 2
is a microfilm which becomes an original image, and the image of this microfilm is illuminated by an illumination lamp 3 and a condensing lens 4 housed in an illumination case 10. Normally, the image of the microfilm 2 is enlarged and projected onto a screen 9 via a projection lens 5 and mirrors 6, 7, and 8. When the user wants to obtain a copy image, when the user presses a copy button (not shown), the mirror 7 rotates in the direction of arrow A and retreats out of the projection optical path.
moves in the direction of arrow B and rises to position E indicated by the dotted line, and then descends in the direction of arrow B' at a speed synchronized with the rotation of the photosensitive drum 13. During this downward movement, the image of the microfilm is placed on the photosensitive drum 13. The exposure is scanned. A known charging device, toner developing device, transfer device, cleaning device, etc. are arranged around the photosensitive drum 13, and the visible image formed on the photosensitive drum 13 is transferred to a copying paper 14, and then fixed by a fixing device. It is fixed and a copy image is obtained on copy paper. 16 is an exposure slit, 15 is a copy paper storage cassette, and arrow C
A cassette 15 stores a large number of copies. The cassette 15 is placed on a cassette mounting table 25, and when the cassette 15 is placed at a predetermined position on the cassette placing table, the copy paper 14 is transferred to the paper feed roller 1.
7 makes it possible to feed paper. 18 is a heat or pressure fixing roller, 19 is a copy paper guide plate, and 20 is a paper discharge tray from which copy paper on which a copy image has been formed is discharged. A series of arrows D outlines the copy paper transport path.

A portion of the paper output tray 20 is placed inside the main body frame 1, and it is possible to take out copy sheets stacked on the paper output tray 20 through an opening 21 provided in the outer wall of the main body frame 1, and to copy images on the copy paper. Confirmation can be made.

The lighting case 10 consists of a rectangular machine box surrounding the lamp 3 and the condensing lens 4, and has openings 4a and 4b for lighting windows in the upper and lower parts. The light generated from the lamp 3 passes through the aperture 4a to illuminate the microfilm 2, and a portion of the light passes through the aperture 4b to illuminate the copy image surface of the copy paper on the paper discharge tray 20. Since the copy paper discharged to the paper discharge tray 20 is illuminated by the lamp 3, the user can easily visually check the presence or absence of the copy paper and the finished state of the copy image on the copy paper.

In the embodiment described above, the discharge tray is directly illuminated with light from the document illumination lamp, but the light from the lamp may be guided to the discharge tray via a light guiding member such as an optical fiber.

The present invention is applicable not only to microfilm reader printers, but also to known copying machines that use reflective originals, and image forming devices that convert an original image into an electrical signal and use a printer such as a laser beam printer to produce a copied image. be able to.

In addition, in the embodiment, a part of the paper output tray is placed inside the device, but even if the entire paper output tray protrudes outside the device, copy paper on the paper output tray will disappear when the device is used in a dark environment. It's getting dark, so
Similar effects can be obtained by the present invention.

[Effects] As described above, according to the present invention, it is possible to easily check the presence or absence of a copy sheet and the quality of a copy image.
Moreover, there is no need to provide special lighting means,
The device can be made smaller and less bulky.
