Abstract:
1. A sheet conveyance device comprising: a conveying portion configured to be driven by a drive force transmitted from a drive source to convey a sheet-like member; a first sensing portion disposed upstream the conveying portion in a conveyance direction of the sheet-like member, and configured to sense a leading end of the sheet-like member in the conveyance direction of the sheet-like member conveyed toward the conveying portion; a second sensing portion disposed downstream the conveying portion in the conveyance direction of the sheet-like member, and configured to sense the leading end of the sheet-like member in the conveyance direction of the sheet-like member conveyed by the conveying portion; a control portion configured to make the conveying portion stop until a predetermined setting time has elapsed after sensing of the leading end of the sheet-like member in the conveyance direction of the sheet-like member by the first sensing portion, deflects the sheet-like member, and outputs a drive signal that drives the conveying portion when the setting time has elapsed; and wherein the control portion is further configured to: wherein the control portion changes the setting time when the response time is longer than a first threshold that is set as a limit value at which a collision sound by deflection of the sheet-like member starts emanating, and when the response time is shorter than a second threshold that is set as a limit value at which correction of inclination of the sheet-like member due to a stop of the conveying portion becomes insufficient, and does not change the setting time when the response time is within an allowable range in which the response time is equal to or longer than the second threshold and is equal to or shorter than the first threshold.
