Claim Text:
1. An image reading device comprising: a sheet setting portion on which a sheet is set; a conveying unit configured to convey the sheet along a conveying path in a conveying direction at a first predetermined velocity, the conveying path having a reading position and a detection position upstream of the reading position in the conveying direction; a reading unit disposed on the conveying path and configured to read the sheet being conveyed by the conveying unit at the reading position; a detecting unit configured to detect the sheet passing past the detection position; a controller configured to control the conveying unit to initiate conveyance of the sheet, and configured to control the reading unit to start reading the sheet when the detecting unit detects the sheet; and a pressing member configured to press, toward the reading unit at a first predetermined pressure, the sheet conveyed past the reading position; wherein the controller is further configured to control the conveying unit to convey the sheet at a second predetermined velocity slower than the first predetermined velocity when the detecting unit fails to detect the sheet after a prescribed period of time has elapsed since the conveying unit initiates the conveyance of the sheet, the prescribed period of time being set based on a duration in which the conveyance of the sheet from the sheet setting portion to the detection position at the first predetermined velocity, and wherein the controller is further configured to control the pressing member to press the sheet toward the reading unit at a second predetermined pressure lower than the first predetermined pressure when the detecting unit fails to detect the sheet after the prescribed period of time has elapsed since the conveying unit initiates the conveyance of the sheet.
