Abstract

PURPOSE:To make it unnecessary to position an original at each time of page advance by providing an original platen on which the original is faceup placed, a flood lamp arranged above the original platen, and a reflecting mirror which leads the reflected light from the original to a lens. CONSTITUTION:An original platen 1 on which the original is faceup placed, a flood lamp 4 arranged above the original platen 1, and a reflecting mirror 3 and a fixed reflecting mirror 5 which lead a reflected light beam 11 from the original to a lens 7 are provided. The flood lamp 4 and the reflecting mirror 3 constitute a movable reflecting mirror 2, and printed sheets as well as books may be used as originals. The original platen 1 constitutes the upper face of a copying machine body. A slide groove is provided in each of this side and the far side and is used to support the moving reflecting mirror 2 and also as the passage hole of a cable. The fixed reflecting mirror 5 leads the light from the original to the hole and sends it into an optical path length fixing mechanism 6. Thus, the operator can copy the original while watching the original surface to be copied, and positioning of the original is facilitated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a copying machine that guides reflected light from an original to a lens and forms an image on a photosensitive drum to make a copy. Concerning a copying machine that can make copies.

[Prior Art] In a conventional copying machine of this type, a floodlight that illuminates the original, a reflector that guides the reflected light from the original to a lens, a lens, an electrophotographic system including a photosensitive drum, a fixing device, etc. are all internal. It was designed to be placed face down on the top document holder to make copies.

[Problems to be solved] In the conventional copying machine described above, copies were made with the original side facing down, so when copying books etc., the original side had to be opened and copied. It must be placed face down and within the specified position indicator. Particularly in the case of books, the above-mentioned operation is required every time a page is changed, which has the drawback of increasing the number of copying steps.

[Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned conventional problems, and it is possible to copy an original by placing it face up, so that the original can be copied while looking at it, and it is possible to easily align the original. Another object of the present invention is to provide a copying machine that does not require alignment every time a page is changed when copying books and the like.

To this end, the present invention provides a copying machine that guides reflected light from an original to a lens, forms an image on a photosensitive drum, and copies the image. The present invention also provides a copying machine characterized by comprising a reflecting mirror that guides reflected light from a document to a lens.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is an external perspective view of a copying machine according to an embodiment of the present invention;
FIG. 2 is a schematic explanatory diagram showing the internal mechanism. In the figure, 6 is an optical path length constant mechanism, 7 is a lens, 8 is an electrophotographic system including a photosensitive drum 8a, 9 is a fixing device, 10 is a sheet of paper, and 14 is a hopper, which are the same as in the conventional system. In this embodiment, there is a document table 1 on which a document 15 is placed facing upward, a light emitting lamp 4 disposed above the document table 1, and reflected light 1 from the document 15.
1 to a lens 7 and a fixed reflecting mirror 5 are provided. The floodlight lamp 4 and the reflecting mirror 3 constitute a movable reflecting mirror 2, which is movable. The manuscript 2 includes things printed on a single sheet of paper and even books. The original table 3 directly constitutes the upper surface of the main body of the copying machine. Reference numeral 4 denotes a slide groove, and one slide groove 4 is provided at the front and one at the back, and serves as a support for the movable reflector 2 and a passage hole for a cable. The fixed reflection fi5 guides the light from the original 2 to the 66 and sends it into the optical path length constant mechanism 6. The hopper 7 is for storing paper 10. Further, the print output is output every time the movable reflecting mirror 1 scans.

To explain the operating principle with reference to FIG. 2, the document on the document table 1 is illuminated by the floodlight 4 in the movable reflector 2, the reflected light 11 is reflected by the reflector 3, and the fixed reflector fi5.
It is reflected again and enters the optical path length constant mechanism 6. Here, the optical path length is kept constant. The reflected light that has passed through here forms an image on the photosensitive drum 8a of the electrophotographic system 8 by the lens 7, and is exposed to light. The paper 10 is to be outputted by the fixing device 9.

[Effects of the Invention] As explained above, the present invention provides a copying machine that guides reflected light from an original to a lens and forms an image on a photosensitive drum to make a copy. The copying machine is characterized by being equipped with a projector lamp placed above and a reflector that guides the reflected light from the original to the lens, so that when copying, the original surface can face upward, and as a result, the copy is not made. You can copy while looking at the original surface.

Therefore, positioning of the original becomes easy. Furthermore, when copying an M manuscript such as a book, it is possible to minimize the effort required to position the manuscript face down at each page break. This has the advantage that it is only necessary to perform a page break every time scanning is completed.
