发明名称 Camera with date entry
摘要 A camera capable of entering the date a picture is taken onto a film loaded therein comprises a digital date indicator for indicating the same date as the calendar date, an optical system for passing light from the date indicator onto part of the film load and for focussing the light thereon, a sight window for permitting the date indication provided by the date indicator to be viewed from the exterior of the camera, and a light shield which prevents light impinging on the sight window from reaching the film surface when a picture is taken.
