Abstract
PURPOSE: To make it possible to make the device small-size and light-weight, by making it possible to display film count with the liquid crystal display device by utilizing the incorporated CPV.
CONSTITUTION: Shutter speed control and the time operation such as date data recording are processed by CPU13 consisting of the C-MOS with quartz vibrator 15 as the oscillation source. The film winding-up signal is supplied through sensor 20 from the winding-up mechanism part, which is composed of winding-up lever 3, winding-up shaft 9, and so on, to the CPU and is subjected to the data processing, and this data processing signal is supplied to liquid crystal display device 1, which is provided on the outside circumference face of the camera, through driver 14, thereby displaying the count number of films. Current consumption is very little because of liquid crystal display.
