Abstract
In a data printing device built in a camera body, the data carrying disc is located close to the bright frame in the viewfinder optical system so that the data may be viewed together with the bright frame in the viewfinder without an additional diopter correcting lens. The data carrying plate consists of a number of discs carrying different data of different diameter so that the data carrying portions of the different data carrying discs may face to the film in the camera directly, namely without any intervention between the data carrying portions and the film, whereby sharp images of the data are printed. A light intercepting plate is provided in parallel to the data carrying discs to selectively print the data.
