Conveyance controller, printing apparatus, method of conveying printing medium, and printing medium conveyance apparatus

摘要

This invention includes an input operation unit which accepts the operation of selecting a first or a second printing medium and outputs information indicating the selected printing medium, a conveyance path, a conveyance mechanism which conveys the selected printing medium in the conveyance direction, and a control unit. The conveyance mechanism includes a main roller, a driven roller which presses the main roller through the selected printing medium, a rotation member having a cam shape, and an elastic member which deforms to change a pressing force in accordance with the rotational position of the rotation member. The control unit rotates the rotation member to the first rotational position when the first printing medium is selected, and rotates the rotation member to the second rotational position where the pressing force becomes smaller than that at the first rotational position when the second printing medium is selected.

主权项

1. A conveyance apparatus, comprising:
an input operation unit configured to perform an operation of selecting, as a printing medium, a first printing medium or a second printing medium, obtained by coating a surface of a printing medium with a liquid having a higher viscosity than water, and output information indicating the selected printing medium; a conveyance path through which the selected printing medium passes; a conveyance mechanism provided on said conveyance path and configured to convey the selected printing medium in a conveyance direction; and a control unit connected to said input operation unit and said conveyance mechanism, wherein said conveyance mechanism includes:
a main roller,a driven roller which presses said main roller through the selected printing medium and rotates in a direction opposite to a rotating direction of said main roller upon rotation of said main roller,a rotation member having a cam shape, and an elastic member which deforms in conformity with the cam shape at the time of rotation of said rotation member to change a pressing force to press said driven roller against said main roller in accordance with a rotational position of said rotation member, and wherein said control unit rotates said rotation member to a first rotational position when the selected printing medium indicated by the information is the first printing medium, and rotates said rotation member to a second rotational position where the pressing force becomes smaller than the pressing force at the first rotational position when the selected printing medium indicated by the information is the second printing medium.
