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.

An electronic print board, comprising

a frame;
a driving roller and a supporting roller rotatably mounted to said frame in vertical alignment;
an endless belt trained over said driving roller and said supporting roller so as to be movable thereon by said driving roller;
a writing medium wrapped around said driving roller and said supporting roller on said endless belt so as to substantially entirely surround said endless belt, said writing medium having a writing surface on one entire side thereof to thereby form an endless band-shaped screen having a flat writing surface portion extending between said driving roller and said supporting roller, said writing surface being formed of a material receptive of and permitting easy erasure of picture images applied thereto with a writing instrument;
attaching means for detachably and reattachably attaching said writing medium to said endless belt, said attaching means including a first attachment member on said endless belt and a second attachment member on a rear surface of said writing medium detachably and reattachably attached to said first attachment member;
means, including a light source and a lens, for directing light onto said writing medium and through said lens to form a reduced scale image of a picture image on said writing medium;
a readout sensor, disposed so as to receive said reduced scale image, said sensor including means, responsive to said reduced scale image, for providing a readout picture image;
and
recording means, connected to said readout sensor and responsive to said readout picture image, for recording a picture image on a recording paper.
