Embodiment Construction

[0040] according to figure 1 and figure 2 A first embodiment of the present invention will be described. figure 1 The state of supporting the main base paper roll 11 by the main base paper roll support device provided on the printing device is shown. This main base paper roll 11 is formed like this: the elongated main base paper 13 is wound on the outer periphery of the hollow cylindrical paper core 12 as the core to form a roll shape, and one end side of the paper core 12 forms a protruding part 14. The protruding portion 14 protrudes outward from the end surface of the main base paper 13 wound on the paper core 12 . The value of the protrusion amount "M" of the protruding portion 14 is appropriately set to a different value for each main base paper roll 11 depending on the size "L" and type of the main base paper 13 . The inner diameter of the paper core 12 is fixed for each main base paper roll 11 . In addition, in each main base paper roll 11 , the other end side of...

Abstract

A support device of a main paper roll for printer and supporting the main paper roll. The main paper roll winds the elongated main paper roll around the core to form a scroll. A terminal of the core constitutes the projecting part which projects outward from the transverse plane of the main paper roll of being winded to the core. The support device has a support part which supports above projecting part. Each projecting size of projecting part of the main paper roll above is different. By sensing the state of the projecting part supported by the support part, it is judicable whether the main paper roll supported by above support part is suitable or not.

Description

technical field [0001] The invention relates to a main base paper roll supporting device and the main base paper roll. Background technique [0002] At present, in the plate making department installed on the printing device, the main base paper roll is mostly used. The main base paper roll is formed by winding the long strip of base paper around a core such as a paper core to form a paper roll. The main base paper pulled out in the roll state is thermally perforated, the main base paper is made into a plate, and the main base paper is wound around the outer peripheral surface of the printing plate cylinder for printing. [0003] Depending on the size and type of the main base paper, there are various specifications of the main base paper roll, and among the various specifications of the paper rolls, there are cases where some types of printing devices are suitable, but some printing devices are not suitable for them. Therefore, it is necessary to be able to easily confirm ...
