PURPOSE:To place a specified input sheet in a read state without requiring push- aside operation for the input sheets, by projecting a couple of left and right lug pieces for extraction from one side of each input sheet to use the lug pieces as indexes. CONSTITUTION:A motor 9 outputs one motor timing signal on every turn. Then, a CPU42 increase the contents of an area R2 of an RAM44. When it is decided that the counted number is ''0'', an area R3 is read, 1 is added to the number of a lug piece, and the sum is stored. Then, the number of lug pieces in the area R3 is read and when it is decided that the read number is equal to the specified number of lug pieces stored in an area R1, a lower roller 13 is energized toward an upper roll 11 to clamp a desired lug piece 7 between the upper and lower rolls 11 and 13; and the input sheet 1 is drawn out through the rotation of the lower roll 13 and sent to a keyboard surface for necessary key input operation. |
