Patent ID: 7523932

Claim:
A sheet member conveying apparatus comprising: a conveying mechanism that sequentially conveys a plurality of sheet members one by one; a detecting portion on that detects a conveyance state of each of the sheet members conveyed by the conveying mechanism; a controller that sets a conveying speed at which the sheet member is conveyed by the conveying mechanism based on the conveyance state of each of the sheet members detected by the detecting portion, wherein the controller determines whether or not the sheet member has been conveyed normally based on the conveyance state detected by the detecting portion, and increases the conveying speed in a stepwise manner to a conveying speed at which a next sheet member is conveyed by the conveying mechanism based on a current conveying speed until the conveying speed reaches a maximum speed, when the controller determines that the sheet member has been conveyed normally; a first number storage portion that stores data of the number of normal conveyance which represents the number of consecutive normal conveyance of the sheet member performed by the conveying mechanism, and wherein the controller updates the data of the number of normal conveyance stored in the first number storage portion based on the determination result of whether or not the sheet member has been conveyed normally, and increases the conveying speed at which the next sheet member is conveyed by the conveying mechanism more than the current conveying speed, when the data of the number of normal conveyance is a predetermined first setting number.
