Device for measuring in black and white or colour originals that are transparent at least in the measurement region

摘要

The measuring device is intended for the transmission measurement in black and white and colour of measurement originals. According to the invention, the measurement light source (1) which produces the focused measurement light beam (1') is arranged on one side in relation to the original bearing surface (9) which is transparent at least in the measurement region. Provided on the other side are the photocell (14) and a projection light source (16) which produces a projection light beam (16'). A reflector (10), such as a perforated mirror or the like, which transmits the measurement light beam (1') and reflects the projection light onto a ground glass screen (22), is arranged between the measurement light source (1) and the original bearing surface (9), and a lens (8) which is effective for both light beams is arranged between the reflector (10) and the original bearing surface (9). <IMAGE>
