In summary, the first supporting shaft 110 and the second supporting shaft 120 of the sheet-like medium conveying mechanism 010 provided in this embodiment jointly support the limiting frame 210, so as to ensure the parallelism of the first supporting shaft 110 and the second supporting shaft 120 by using the limiting frame 210; the first roller 220 and the second roller 230 of the sheet medium conveying mechanism 010 are both located between the two limiting walls 211 of the limiting frame 210, so that the positions of the first roller 220 and the second roller 230 are easy to align; in this way, the problem of sheet-like medium deviation that occurs when the sheet-like medium conveying mechanism 010 conveys the sheet-like medium can be improved.

The sheet-like medium conveyance mechanism 010 according to the present embodiment can be used in a sheet-like medium processing apparatus 020, for example: a printer, a scanner, an automatic ticket checker, and the like, and therefore the problem of the sheet medium running out of position, which occurs when the sheet medium processing apparatus 020 conveys the sheet medium, can be improved.
