PURPOSE: To easily and speedily perform vertical adjusting work of a detecting position of a copying roller by arranging an operation lever whose male screw of an intermediate part is screw-fitted to a female screw of a piece member and tip is rotatably connected to a stopper pin.
CONSTITUTION: An operation lever 13 whose tip is rotatably supported with a stopper pin 12 is rotated, and the operation lever 13 is screw-fitted to a piece member 11, and a distance between a second fulcrum A2 and a third fulcrum A3 is made large. According to this, a detector holding member 4 supported through respective link mechanisms by being energized by a spring means 8 is positionally displaced downward, that is, in the Z1 direction. When the operation lever 13 is rotated so that a distance between the second fulcrum A2 and the third fulcrum A3 becomes small, the detector holding member 4 is positionally displaced in the Z2 direction. In this way, when the operation lever 13 screw-fitted to the piece member 11 is rotatably operated, a position of a detector 3 to a support member 1, that is, a position of a copying roller 301 can be adjusted in the vertical direction.
