Claims

[Claims for Utility Model Registration] A hood portion formed to be attachable to the front surface of a CRT display and housing therein an image sensor capable of electronically reading a still image displayed on the CRT display; , a printer unit for converting a time-series image signal output from the image sensor into a position signal to reproduce the still image and print out the image sensor; a signal processing means that generates a plurality of digital signals by a plurality of comparators each having a threshold value set according to the level of the output signal, and generates a plurality of types of binary signals from these digital signals; an image memory for storing a dot matrix signal, a dot matrix conversion means for converting the binary signal read from the image memory into a plurality of types of dot matrix signals having different dot densities for printing, and a dot matrix conversion means for converting the dot matrix signal by the printer section. 1. A copying device for a CRT display, comprising: position signal converting means for converting a position signal into a position signal for outputting a print at a specific position on printing paper.
