Document Type and Number:
Japanese Patent JPS5219557
Kind Code:
Y2
Abstract:
A data recording device for incorporation in a camera which enables appropriate data associated with a particular subject to be recorded in the same frame on a film or at an appropriate position outside of the frame on the film in the camera by removably inserting therein a data capsule including data rings bearing the data to be recorded. The selected data are illuminated by means within the capsule and projected onto the film through a projection lens located in the camera body. This projection lens is automatically covered or sealed by a mirror on a spring-loaded lever when the data capsule is removed from the camera so that external light is prevented from entering the projection lens and passing onto the film. On the other hand, the projection lens is automatically uncovered to project the selected data which is reflected by the mirror when the data capsule is inserted into the camera.
