Abstract

PURPOSE:To improve the applicability of an electronic copying device when a writing medium is used as a screen, by synthesizing the picture drawn on the writing medium and the projected picture and recording these synthesized signals by a printer. CONSTITUTION:A white flat plate part 2 to which the pictures can be drawn and an operating panel 8 are provided to an electronic copying device main body 1. While an original board for OHP original 4 and a projection head 5 containing a lens and a mirror for projection onto the part 2 are provided to a recording device main body. Here the part 2 is made of a long-sized sheet 9 and the both ends of the sheet 9 are taken up with operation of the panel 8. The pictures drawn on the sheet 9 are illuminated by a fluorescent lamp 10 and read by a photoelectric transducer 12 via a lens 11. These read picture signals are synthesized with the pictures projected by the head 5 and delivered to be recorded by a printer. Thus the sheet 9 is used as a screen. This improves the applicability of an electronic copying device.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a multilayer copying device that reads and records I1IIi image information on a writing member capable of writing with IRF.

(Traditional Techniques &) Traditionally, when using a blackboard for meetings, meetings, etc., it was difficult to take the time to transcribe what was written on the blackboard into a notebook, etc., and to listen to the explainer's explanation while transcribing. In order to save time and effort, a so-called electronic blackboard copying device has been proposed and is actually in use, which reads and records image information such as characters and figures written on a blackboard 1-. The writing surface of this electronic copying machine is white, and can be used as a screen for overhetblond printers (hereinafter referred to as OHP), slides, etc. Therefore, in a meeting or the like, there are cases where OHP materials or slides are projected onto the writing surface of an electronic copying device, and new content is added to the writing surface while explaining or discussing.

(Problem to be Solved by the Invention) However, in the case of such conventional technology, since the image information written on the writing surface of the device is only read and recorded, the OHP or The images on the slide cap cannot be recorded, and these projected images must be transcribed onto a notebook, which is troublesome, and the writing surface of the device cannot fully utilize its role as a screen. was there.

Therefore, the present invention has the following points. This was done to solve the problems of the prior art described above, and the points 1-1 are as follows:
It is an object of the present invention to provide an electronic copying device capable of recording an image projected onto a writing surface as well as an image of smudged writing on the writing surface.

(Means for Solving the Problems) Book 9: In order to achieve the above objectives, IJI provides a simple writing medium, a means for reading image information on the writing medium, and a means for reading image information by the reading means. J! In an electronic copying device equipped with,
It has means for projecting an image of an information recording medium onto the writing medium, and means for reading the image of the information recording medium, and the image on the writing medium and the information recording medium projected onto the writing medium. It is configured to combine and output images.

When the sheet 9 with an image written on the plate part 2 is wound up into a roll, the image written on the surface of the sheet 9 is illuminated by the fluorescent lamp IO as a light source, and the image written on the surface of the sheet 9 is illuminated by the lens 11. It is read out by the photoelectric conversion element 12 of the CCD''V via the photoelectric conversion element 12 of the CCD''V.

FIG. 3 is a schematic diagram showing a recording device that also serves as a projection device. When projecting, cover 7 is opened as shown in FIG. 0HPj''JC draft 4 is placed on the OHP rack lamp 14, and the OHP draft 4 is illuminated by the OHP rack lamp 14, and projected onto the plate section 2 via the projection radar 5.When reading and recording the manuscript, the cover is 7 is closed, the OHP document 4 on the document table 131 is illuminated with a fluorescent lamp 15 as a reading light source, and the document table 13 is scanned in the direction of the arrow, and a CCD or the like is scanned through the lens 16. The photoelectric conversion sensor r17 reads the image of the document 4 on the OHP.

Reference numeral 18 denotes a printer that records images read by the photoelectric transducers 7' l 2 and l 7 . In addition,
Fix the document side and turn on the fluorescent light on the reading side15. The lens 16 and the photoelectric converter 17 may be moved.
