Abstract

Abstract A microfilm attachment for an electrostatic copying machine. The copying machine includes a scanning window and a roller exposed at the upper surface thereof. The microfilm attachment is placed on top of the machine and includes a roller which engages the machine roller. The attachment roller is coupled to a plate which carries a microfilm original to be copied. As the machine cycles, the machine and attachment rollers turn, and the microfilm original is moved. A projection lamp initially images the microfilm on a screen. At the start of the copying cycle, a mirror in the attachment is moved to direct light transmitted through the moving microfilm original to the scanning window for the purpose of exposing copy paper which is moved past an exposure window in the machine at the same time. Because when the microfilm original is initially imaged on the screen it is centrally disposed relative to the machine scanning window, at the start of the copying cycle the microfilm original is actually moved in the reverse direction until it clears the scanning window. Thereafter, it is moved in the forward direction past the scanning window. At the end of the scanning sequence, the microfilm original is returned in the reverse direction to the initial position. The copy paper feed begins while the microfilm original first moves in the reverse direction so that the copy paper reaches the exposure window just when forward movement of the microfilm original is to begin. The microfilm attachment includes several switches which are operated depending upon the position of the microfilm original during the sequence. These switches are extended through connectors on the attachment and the copying machine to the control circuit within the machine so that the machine is properly sequenced with respect to movement of the microfilm original.
