To make a conveying operation highly efficient and thereby shorten a conveyance time by setting a position for a conveyor based on previously stored identical memory data and consequently, dispensing with an overlapping preparatory work for positional setting, when repeatedly conveying sheets of an identically punched shape which are through with a fabrication work using a punching machine.

In the conveyance device which conveys punched sheets held between endless belts 2, 3 arranged opposite to each other above and below, a belt moving means 10a which corresponds to each of plural rows of the endless belts 2, 3 is installed so that the position of the endless belts 2, 3 is freely adjustable in the width direction of the device. In addition, data corresponding to a position which is not lapped over a position for punchings generated as a result of a sheet punching operation. When the sheets of an identically punched shape are again conveyed, the endless belts 2, 3 can be automatically set at specified positions based on the stored data.
