Photographic printing tape puncher
摘要:
A photographic printing tape puncher for recording, on a paper tape, information on exposure correction for each of image frames formed on an original picture film before the film is used to perform printing. A frame number reading means reads bar codes which represent frame numbers and which are recorded on a part of the original picture film. The information thereby read is recorded on the paper tape along with items of information on exposure correction for the corresponding image frames. The items of exposure correction information and the frame numbers relating to the image frames are recorded on the paper tape constantly in correspondence with each other. It is therefore possible to easily obtain desired exposure correction information by searching a corresponding image frame number on the paper tape.
