1. A sheet discriminating device comprising:
a first conveying structure and a second conveying structure that are arranged at a predetermined distance from each other in a conveying direction of a sheet and that are configured to convey the sheet; and an information detecting means that is provided between the first conveying structure and the second conveying structure such that a detection range thereof is not blocked, and that is configured to detect information from the sheet, wherein a first entry angle θ1 that is formed by a first entry direction in which the sheet enters a space between the first conveying structure and the second conveying structure from the first conveying structure and a conveyance reference plane that is set between the first conveying structure and the second conveying structure, and a second entry angle θ2 that is formed by a second entry direction in which the sheet enters the second conveying structure from the space between the first conveying structure and the second conveying structure and the conveyance reference plane are set to be equal to or less than respective predetermined values that depend on positions of the first conveying structure, the second conveying structure, and the information detecting means and a distance up to which the sheet is allowed to be separated from the conveyance reference plane at the position of the information detecting means.
