Description

[Detailed explanation of the idea] This idea is related to a recording paper storage device consisting of a box. It is something to do.

Conventionally, there are various types of recording paper storage devices used in analog recorders, printers, and the like.

However, many recording paper storage boxes, which consist of a box body into which the recording paper is inserted, are simply rotatable around an axis and are held in place, and there is inevitably some play from side to side. The left and right positions of the recording paper in the recording paper feeder will be different from the left and right positions of the recording paper in the recording paper feeding section, and when the recording paper is fed out, the recording paper will shift left and right, causing the recording paper to get caught and damaged. It was difficult to feed the recording paper easily and stably.

Furthermore, since there is a shift in the horizontal direction of the recording paper, there is a drawback that the recording accuracy becomes extremely poor, especially in the case of analog recording in which pen writing is performed on the recording paper on which scales are printed in advance.
