Abstract
A still camera having a marking mechanism for forming a message or title along one edge of each picture taken by the camera. The marking mechanism is preferably a dot matrix printer synchronized with the motor that advances the film after each picture-taking event. During the film-advance period the printer mechanism operates automatically to form a message (title) on the previously-taken picture. A manual keyboard is provided to select (vary) the message.
Claims4
A still camera comprising:
- a film advance motor operable during the period between successive picture-taking events;
- a dot matrix printer means operable to print a single column of dots on the film in a direction normal to the direction of film advance, whereby repeated operation of the printer means forms a message of individual characters extending parallel to the direction of film advance;
- a manual keyboard means;
- a memory receiving signals generated by the keyboard means;
- oscillator means operable to generate electrical pulses in synchronism with the film advance speed;
- and
- a clocked decoder means connected to the memory and controlled by the oscillator means so that the characters printed on the film during the film-advance period correspond to the characters originally put into the memory by operation of the keyboard.
