Summary:To more appropriately correct a condition used for discrimination of the type of a sheet.SOLUTION: A sheet type discrimination device of one side of the present invention comprises: a physical property value detection unit 26 that detects the physical property value of a sheet; a sheet type discrimination unit 17 that discriminates the type of the sheet based on the physical property value of the sheet detected by the physical property value detection unit 26 and a predetermined condition indicated by the physical property value; an input unit that receives input of information on the type of the sheet; and a condition change unit 18 that, when the type of the sheet input to the input unit and the type of the sheet discriminated by the sheet type discrimination unit 17 are different from each other, calculates the difference between a first physical property value of the sheet detected by the physical property value detection unit 26 and a second physical property value associated with the sheet input to the input unit, and corrects the condition with the difference as a shift amount.SELECTED DRAWING: Figure 2 【課題】シートの種類の判別に用いられる条件を、より適切に補正できるようにする。【解決手段】本発明の一側面のシート種類判別装置は、シートの物性値を検知する物性値検知部26と、物性値検知部26が検知したシートの物性値と、物性値によって示される所定の条件とに基づいて、シートの種類を判別するシート種類判別部17と、シートの種類の情報が入力される入力部と、入力部に入力されたシートの種類と、シート種類判別部17により判別されたシートの種類とが異なる場合に、物性値検知部26が検知したシートの第1の物性値と、入力部に入力されたシートに対応付けられた第2の物性値との差分を算出し、該差分をシフト量として条件を補正する条件変更部18と、を備える。【選択図】図2
