Abstract

PURPOSE: To detect surely the passage of the copy by a method wherein a recessed portion is provided on a half way of a copy transferring way and a free lever moving upwardly and downwardly in accordance with a tension given to the copy being passed therethrough is provided at the recessed portion while a detector is operated by the lever.
CONSTITUTION: In a facsimile device and the like, when an initiating switch is pushed, revolutions of stepping motors 9, 24 are initiated and a separating roller 22 cooperating with a brake plate 27 sends out a lowermost copy on a carrier table 21 to a copy reading passageway 4 through a transferring way 33. Next, when the copy is sent by a paper feeding roller 5 and a front end thereof is detected by a photoelectric element 15, both of the motors 9, 24 are stopped, thereafter only the motor 9 is rotated again and the copy is read by a reading device 13. In this moment, a rear end of the copy is pinched by the roller 22 and the brack plate 27, therefore, the copy is tensed. Accordingly, a free lever 32 is elevated about an axle 34 to shield a passageway of light projected to a photoelectric element 38 and the motor 24 is started.
