Abstract
Sheet counting apparatus comprises a sheet support (2-4) for holding a stack of sheets (13) to be counted. A sheet feed device (14) moves the sheets individually from a first position to a second position while they remain held together in the stack (13). A counter (23) monitors movement of the sheet as it is moved from the first position to the second position, and increments a count when such movement is detected.
Claims15
A method of counting sheets held together in a stack, the method comprising:
- successively moving a first end of each sheet of the stack individually from a first position to a second counted position, while second ends of the sheets remain held together in the stack;
- independently from moving each sheet, directly monitoring, for each sheet, movement of the first end of that sheet as that sheet is moved from the first position to the second counted position;
- and
- incrementing, for each sheet, a count when the movement of that sheet is detected.
