Abstract

1,105,122. Feeding sheets. EASTMAN KODAK CO. 1 April, 1965 [6 April, 1964], No. 13809/65. Heading B6B. A sheet responsive device for sensing the passage of a sheet as the sheet moves along a given path, comprises a resiliently mounted arm 16, having a curvilinear end portion 18, for intercepting and engaging the leading edge of a sheet 12 and for movement in and along the sheet path from a first position to a second position, and camming means 20 on the arm for disengaging the arm from the sheet when the arm is in the second position. As shown, a sheet 12 is transported upwardly between two opposed sets of conveyer belts 12, 15. The arm 16 has a camming knee 20 just below the curved end 18, and is pulled against two fixed stops 24, 25 by a spring 22. The operating arm 26 of a microswitch 28, which controls the operation of the associated apparatus, is loosely pivotally connected at 30 to the arm 16. When the leading edge of the sheet 12 engages the end 18, the arm 16 is forced upwardly (Fig. 2, not shown) to a position where the knee 20 is engaged by the sheet and cams the end 18 of the arm away from the sheet, whereupon the spring 22 pulls the arm against the stop 25. The switch 28 is operated during the movement of the arm 16 to control, for example, film movement during photographing.
