Abstract:
1. A medium processing apparatus comprising: a medium conveying mechanism operable to convey a specific sheet medium along a medium conveying path in a medium conveying direction; and an information reading section operable to read information recorded on a recording area of the medium when the recording area of the medium passes through an information reading position on the medium conveying path; wherein the medium conveying mechanism includes: wherein a distance in the medium conveying path between the information reading position and a nip portion between the first conveying roller and the first pressure roller is set so that the medium is nipped between the first conveying roller and the first pressure roller when the information reading section reads the medium; and wherein the first driven pulley is disposed upstream of the driving pulley in the medium conveying direction; wherein the second driven pulley is disposed upstream of the first driven pulley in the medium conveying direction; wherein the third conveying roller is disposed at a position other than between the first conveying roller and the information reading position on the medium conveying path; and wherein the third pressure roller is disposed at a position other than between the first pressure roller and the information reading position on the medium conveying path, wherein a diameter of the first conveying roller is larger than a diameter of the third conveying roller; and wherein a diameter of the first pressure roller is larger than a diameter of the third pressure roller.
