摘要： A printing apparatus includes a rotary drum that is provided with a cylindrical body, a rotary shaft, and arm portions, an ejecting unit, a first cooling fan that uses a section formed in the circumferential direction between the arm portions as a passageway of air and that supplies the air, and a first air guide member that is retrofitted to the passageway of the air. The first air guide member is provided with a number a of first guides, a being an integer of 2 or more. The number a of the first guides are configured to guide the air from the first cooling fan to regions that are different positions of the inner surface of the cylindrical body and that are obtained by dividing up the inner surface of the cylindrical body by the number a in the direction along the rotary shaft.

摘要： This printing apparatus is provided with a discharge head, a movement unit for moving a recording medium in a prescribed direction relative to the discharge head, a support member for supporting the recording medium in a position of facing the discharge head, a light-emitting unit for emitting light downstream in the prescribed direction from the discharge head, a first opposing unit disposed between the discharge head and the light-emitting unit in the prescribed direction, a second opposing unit disposed downstream of the discharge head in the prescribed direction, and an optically transparent member that is disposed between the first opposing unit and the second opposing unit and that covers the light-emitting unit from the support member. The optically transparent member is provided between the light-emitting unit and an opening defined between the support-member-side end of the first opposing unit and the support-member-side end of the second opposing unit, light emitted from the light-emitting unit is radiated from the opening onto the recording medium after transmitting through the optically transparent member, and the distance from the opening to the optically transparent member is greater than or equal to 40% of the width of the opening in the prescribed direction.

摘要： An auxiliary member is an auxiliary member that assists in mounting a roll body, which is formed by winding a sheet into a roll shape on a core tube, onto a shaft of a printing apparatus. The auxiliary member includes a cylindrical main body insertable into the core tube, a laser irradiation unit that irradiates laser light from a leading end surface of the main body, and a switch that switches between irradiation and stopping of the laser light from the laser irradiation unit.

摘要： A cleaning liquid supplying apparatus includes a first storage section, a pressure-accumulating second storage section, a plurality of cleaning liquid ejecting sections, a liquid sending section, a plurality of individual flow channel opening/closing sections, and a control section. The first storage section stores cleaning liquid. The cleaning liquid ejecting sections are connected to the second storage section via a plurality of individual flow channels having upstream ends located at positions where the upstream ends are open to a liquid reservoir when a predetermined amount of the cleaning liquid is stored in the second storage section. The liquid sending section is provided midway along a first flow channel and sends the cleaning liquid in the first storage section to the second storage section. The individual flow channel opening/closing sections open/close the respective individual flow channels. The control section controls the liquid sending section so that a pressure in an air reservoir becomes a predetermined pressure.
