1. A drum-type drying device comprising:
a cylindrical drum section that is rotatably supported and rotated by winding a base material on the drum section; a tubular member that supports the drum section so as to allow the drum section to be rotatable about the axis of the drum section; a pair of heater supporting plates each of which is disposed, in an inner cavity of the drum section, apart from the other, the pair of heater supporting plates extending parallel to a direction orthogonal to the axis of the tubular member and being fixed to the tubular member; a mounting unit which extends parallel to the axial direction of the tubular member and is fixed to edge portions of the pair of heater supporting plates, the mounting unit comprising: a plate-like heater guide that has first and second bent portions formed by bending both ends of the heater guide in the axial direction of the tubular member so that the first and second bent portions extend parallel to the direction orthogonal to the axis of the tubular member; engaging portions that are disposed in the inner cavity of the drum section, that are fixed to the tubular member, and that are a pair of groove portions that is formed on the heater guide so as to extend parallel to the axial direction of the tubular member; and a heating section that comprises:
a heater;a plate-like member which supports the heater; andengaged portions that are detachably engaged with the engaging portions, and that are formed in end portions of the plate-like member so that the end portions of the plate-like member are detachably engaged with the pair of groove portions, respectively; wherein the mounting unit further comprises a positioning section that positions the heating section in the axial direction of the tubular member and fixes the heating section, the positioning section comprising:
a first heater unit pressing part that is provided on the first bent portion of the heater guide; anda second heater unit pressing part that is provided on the second bent portion of the heater guide; the first heater unit pressing part is capable of being moved between a locking position where one end portion of the first heater unit pressing part protrudes from an upper surface of the heater guide, and a retreat position where the one end portion of the first heater unit pressing part is under the upper surface of the heater guide; and when the first heater unit pressing part is at the locking position, the heating section is positioned in the axial direction of the tubular member and is fixed by the first heater unit pressing part and the second heater unit pressing part coming into contact with the heating section to restrict the movement of the heating section in the axial direction of the tubular member. |
