Claims

[Scope of Claim for Utility Model Registration] (1) A plate cylinder attachment/detachment device for a rotary mimeograph machine, which is equipped with a plate cylinder which is rotated by wrapping base paper around its outer periphery and storing ink inside; It has an outer periphery opening type bearing part that receives the central boss part at one end of the plate cylinder from above and a pin engagement part that receives and engages the protruding pin at one end of the plate cylinder, and rotates around the horizontal axis on one side frame part of the machine. The plate cylinder has a cylindrical plate cylinder support shaft which is pivotally supported, and a concave bearing part and a pin engaging part into which the central boss part at the other end of the plate cylinder and the protruding pin are fitted by pushing in the axial direction. A rotationally driven plate cylinder rotary disk supported on the other frame part of the body so as to rotate about a horizontal axis, and an inner end shaft part fitted into the inner hole of the central boss part of one end of the plate cylinder. It has a handle operating shaft which is fitted into the plate cylinder support shaft so as to be movable by being biased by a spring so that the inner end shaft is fitted into the inner hole of the center boss part of one end of the plate cylinder, and this handle operating shaft. A lock release that locks the inward movement of the handle operating shaft while the shaft is moved to the draw-out limit position where the inner end shaft comes out of the inner hole of the center boss at one end of the plate cylinder by pulling the handle. in the operation shaft locked state in which the inner end shaft portion of the handle operation shaft is removed from the inner hole of the plate cylinder boss portion;
moving the plate cylinder in the axial direction and lifting it upward;
A plate cylinder attachment/detachment device for a rotary copying machine, characterized in that the plate cylinder can be removed from between a plate cylinder support shaft and a plate cylinder rotary disk. (2) The shaft movement latching means includes a stopper protrusion protruding from the outer circumference of the inner end of the handle mounting tube of the handle operating shaft;
It consists of a shaft bearing body fixed to a base, which has a guide hole for guiding the handle mounting cylinder and has a passage groove for the stopper protrusion recessed inside the guide hole, and the stopper protrusion that has passed through the shaft bearing guide hole is inserted into the handle. The mimeosha wheel according to claim 1 of the utility model registration claim, characterized in that it is configured to be displaced from the position of the protrusion passage groove by rotational operation and to be locked to the opening end surface of the shaft bearing guide port. Turning machine plate cylinder attachment/detachment device.
