Abstract

Abstract An electronic copying apparatus provides a touch sensitive area placed under a paper on which an image is produced. Pressure on the touch sensitive area produced in rendering the image on the paper generates signals which are detected by a processor and stored as a series of pixel positions in a non-volatile solid-state memory array such as a flash EEPROM memory array. The image stored in the memory array may be read from the array by a computer and utilized as are other files in a computer.
