SPT - Konica FT1

Comprehensive technical documentation dedicated to the motor system of the Konica FT-1 camera. This manual provides detailed information on the operation, mechanical structure, and maintenance procedures for the motorized functions of this camera. The document features detailed views of the motor from multiple angles (front view, bottom view, rewind side view) along with explanations of the EE control circuit and release magnets. Complete technical specifications are included, covering the AE coupling range (EV 0.7 to EV 19 at ISO 100 with f/1.8 lens) and precision adjustments for VO2 voltage, automatic exposure, and shutter curtain timing. The film transport system, diaphragm mechanism with driving gears, and operation of the mirror motor and film wind motor relays are thoroughly explained. A comprehensive disassembly section provides step-by-step instructions for removing and reinstalling critical components, while the calibration section covers adjustments for VO2 voltage, exposure control, and shutter curtain travel time. Detailed schematics illustrate component locations, amplifier circuits, and electrical contact points. Troubleshooting guidance addresses common issues including mirror motor failures, shutter resistor problems, and contact anomalies, with symptom identification and corrective procedures.
