Page 6: Section 2 - Operation
Section 2 - Operation Exposure Modes (Shutter and Light Interception Blades) The Miniportrait Model 203 has two exposure modes: single (half- frame) exposure allowing two different portraits on a single sheet of film, and dual exposure allowing a pair of identical portraits on a sheet of film. Accordingly, as shown in Figure 3 the shape of the Shutter Blade (A) and Light Interception Blade (B) in the 203 are different from those in the Miniportrait 403. -
Page 7: Single (Half-Frame) Exposure Operation
Single (Half-Frame) Exposure Operation When Mode Change Lever (1) (Figure 4) is set at single-frame, after the Shutter has been charged, levers (2) and (3) move a second forked Mode Change Lever (4) toward the Motor. Mode Change Lever (4) is set so that pin (a) rests in its forked slot. Figure 4. -
Page 8: Closing Aperture
When the Shutter is released and the Motor runs, pin (b) rotates one-half turn, moving the forked lever (4) in the arrow direction shown in Figure 6. This causes pin (b) to rotate the Light Interception Blade (5), closing the aperture. Figure 6. -
Page 9: Dual-Frame Exposure Operation
Dual-Frame Exposure Operation In the dual-frame exposure mode, lever (1) is held in a neutral position by the spring “A.” This allows the Light Interception Blade to be set in the position shown in Figure 7. Now, as the Motor runs, pin (a) rotates clockwise as the arrows indicate. However, pin (a) does not turn the Mode Change Lever because it is not engaged in the Lever slot. -

Section 3 - Reassembly of Exposure Mode Change Gears Note: Disassembly procedures are basically similar for both the 203 and 403 Miniportrait Cameras. See Section 3 of the Miniportrait 403 Repair Manual. 1. Remove Gear 1 and turn Gear (2) until tip A of the switch contact aligns with the third tooth of Gear (2). - Page 11 3. Next, set the Mode Change Lever in the position for single- frame exposure. Now turn Gear (1) past the Switch contact, within the cam groove C range (Figure 9). The Light Interception Blade should now cover the aperture. Figure 9. Setting positon of mode change lever for single frame exposure 4.
