<p>PURPOSE:To make an ultraviolet ray, dust, etc. difficult to come into a device from a hand fed paper insertion part by providing the opening and closing plate energized by turning at the position closed displaceably on a paper insertion passage. CONSTITUTION:In the case of inserting a form manually a hand feeding table 13 is opened by turning with a shaft 15 as the center. The arms 6, 7 at both sides pivotally supported by a pin 14 on the hand feed table 13 are thereby turned and an engaging shaft 9 is descended along a guide hole 11a. When the engaging shaft 9 is then abutted to the lower edge part of the guide hole 11a, the descent and turning of the arm 6, 7 are stopped and the turning of the hand fed table 13 is also stopped. In this case, an opening and closing plate 5 is moved with the state of abutting to a stopper 17 at its surface by the turning energizing force of a coil spring, its lower end 5e becomes at the position almost coincident with the upper face of the hand feed table 13 at the releasing position of the table 13, and a paper insertion passage 2 is closed.</p> |
