  • Patent number: 4670794
    Abstract: An electronic print board is provided with an endless or continuous writing medium, on which a transparent sheet-shaped writing medium (3) is removably mounted. Any characters and figures written on both the writing media are combined, scaled down, and copied on recording paper by means of a recording device. In addition, another document can be inserted between the two writing media. Thus, the characters and figures written on the document and the transparent writing medium can be combined, scaled down, and copied on the recording paper by means of the recording device.

  • Patent number: 4667254
    Abstract: An electronic print board which includes driving and support rollers rotatably mounted on a frame, an endless belt trained over the rollers, and a writing medium having a flat writing surface, wrapped around the rollers on the endless belt so as to substantially entirely surround the belt to thereby form an endless band-shaped screen. Fixing mediums are provided on the rear surface of the writing medium and the belt to removably mount the writing medium on the belt. A readout sensor receives light reflected from a picture image on the writing medium to provide a readout picture image to a recorder which records the picture image on recording paper. The exposed surface of the writing medium may be erasably written upon by, for example, a felt pen so that the writing medium may be repeatedly reused and easily detached and replaced when worn.
