Abstract

A camera data recording device having an indication means comprising solid-state illuminating element on the back plate of the camera, connected to a control device provided outside the camera by means of a connector, in which various data are selected and set by the control device.

Claims

1. A camera data recording device comprising:

a camera body containing film therein;

a data control device provided separately from said camera body, said control device including data selecting means and data setting means;

solid-state illuminating means being provided at the back of said film within the camera; and

a connecting element for connecting the control device to the illuminating means in said camera body,

said illuminating means being controlled by control signals from the data setting means for recording the digital data on the film within the camera.

2. A camera data recording device according to claim 1, in which the illuminating means is controlled by a synchro-contact means of the camera and illuminates for a predetermined time.

3. A camera data recording device according to claim 1, wherein said camera body contains an image forming optical system and a back plate and in which the solid illuminating means and the image forming optical system are provided on the back plate of the camera and, when the illuminating means illuminates, data are recorded on the film through the optical system.

4. A camera data recording device according to claim 3, in which the optical system includes a reflection optical system in its optical path.

5. A camera data recording device according to claim 3, in which the solid-state illuminating means is an illuminating diode.

6. A camera recording device according to claim 1 wherein said data control device includes a clock oscillator and wherein said data selecting means includes adjustable switching means and said setting means is a switching element and wherein said recording device includes a register for receiving digital control signals corresponding to data set into said data setting means and a decoder for providing drive signals for said solid-state illuminating means.
