Abstract

887,847. Photocopying book pages. SHANNON Ltd. Sept. 19, 1960 [Sept. 17, 1959], No. 31752/59. Class 98(2). A method of photocopying the pages of a book 20 consists of placing the book as shown on a support formed by two transparent or translucent sheets 2 and 4 arranged together in the shape of an inverted V. The structure is mounted on triangular end-walls 8, 10, and may have a light source within it, or may be placed over an exposing device. Flaps 16, faced with layers 18 of soft resilient material, are hinged to the bottom edges of the sheets 2 and 4, and are used to press the pages to be copied firmly against the sensitive paper, which is interposed between the pages and the sheets 2. and 4. Thus satisfactory copies, extending closely into the bound margin, may be made of both facing pages of the book simultaneously.
