4.2Image Rotation

The Prism Unit is rotated to correct any tilt of the image microfilm projected on the Screen.

4.2.1 Prism Rotation

The Auto Image Rotating Knob is linked to the Auto Image Rotating Variable Resistor (VR1). Turning the Knob clockwise or counterclockwise turns the Auto Image Rotating Motor (M5) whose drive is transmitted via a belt to the Prism Gear, thus turning the Prism Unit.

4.2.2 Auto Image Rotating Motor (M5) Control Circuit

When the Auto Image Rotating Knob is at the home position (center), voltage at PJ2C-2 is set at DC2.5V and the Auto Image Rotating Motor (M5) remains stationary.

PJ2C-2 reads fluctuations of the input voltages as the Auto Image Rotating Knob is turned, there by determining the direction of rotation of the Auto Image Rotating Motor.
