发明名称 Data imprinting device for a camera.
摘要 <p>A data imprinting device (10) focuses light emitted from an array (59) of LEDs (1-7) onto the film, exposing the film as it is fed. A single chip microcomputer (57) controls the LED array to imprint data. Some of the LEDs (2 and 3, 5 and 6) in the array are always energized together, while others (1,4,7) are energized independently. The LEDs which are energized together require only a single control line (D2,D4), thus reducing the number of control lines (D1-D5), and consequently permitting reduction in the size of the camera. The group-wise serial activation of the dot matrix columns slightly staggers the imprinted data, but the imprinted characters are fully recognizable. In addition to reducing the number of control lines, the group-wise serial activation also reduces the peak load on the constant circuit, and thereby reduces the size of this circuit. &lt;IMAGE&gt; &lt;IMAGE&gt;</p>
