Abstract: 1412221 Micro-fiche printing XEROX CORP 26 April 1973 [1 May 1972] 19793/73 Heading G2A The frames of a micro-fiche card are macrocopied row by row by passage of the card (between a light source 101 and an enlarging lens 102 (scanning slit 103) on a carriage having a scanning and fly back movement along the X-axis and a stepwise movement along the Y-axis using a continuously rotating xerographic drum 104 from which toner images are transferred to a fan-folded web 106 for quasi book production. The card is held in a mount 20 comprising a pair of hinged frames, the upper frame 21 being opened at the end of the stepwise movement by coaction of a cam follower roll 44 with a cam surface 42 and the lower frame being mounted for Y-axis movement on rails 32 carried by a carriage 35, the carriage being mounted for X-axis movement on rails 31. Each scanning movement is effected (after each switch 69 of a series is actuated by a finger 70 attached to mount 20 and synchronization holes 113 in web 106 pass a photo-cell/light source couple 114) by movement of a rigid drive strap 51  attached to carriage 35, the strap being driven by a variable speed motor while a solenoid 58 is energized. Synchronization of the beginning of each frame with the beginning of each folded web panel is maintained when necessary by varying the speed of motor 55 (making use of photo-cell/ light source couple 114 together with a further couple 115 which senses the passage of successive notches 116, corresponding to the beginning of each frame, on carriage 35). On engagement of a finger 59, attached to carriage 35, with a switch 60, solenoid 58 is de-energized and a fly back motor 63 having a rotary arm 61 is energized, fly back to just before a stop 67 being effected by engagement of a ball 64, attached to arm 61, in a slot in a plate 66 of carriage 35. The last increment of the flyback is effected by a magnet 68, whereupon finger 70 actuates switch 69 to stop motor 63 and re-energize solenoid 58. The stepwise movement is effected at the end of a scanning movement by the co-operation of a series of depending pins 85 carried by mount 20 with a mechanical gate 83 Figs. 5-7 (not shown) under the action of a constant force spring 80, reverse movement being freely effected using a handle 40 attached to the lower frame of mount 20 by a pin camming action. Complete shut-down is effected on actuation of switch 60 after actuation of the last switch 69.
