Abstract
PURPOSE: To set a detection level automatically by writing information on the thickness of a sheet on control data from the control sheet and by setting the margin value of the detection level to a corresponding sheet double-feed detecting method by reading the information on the thickness of the sheet prior to the start of a job.
CONSTITUTION: The sheet feeding method is provided which operates by being supplied with control data on the format of an internal or external memory or a control sheet to start a job process; information on the thickness of the sheet is previously written on control data 21, which is supplied to register 23 via interface 22. Prior to the start of the job, the thickness information is read out to supply selected detection levels to drivers 241 to 243 and slicer circuit 25 turns on one of drivers 241 to 243; the output is supplied to either input of comparator circuit 14, thereby setting the margin value of the detection level of comparator circuit 14 as a double-feed detecting method which detects the information from photo sensor 5.
