A sheet package producing system includes at least a cutter module and a packaging module. The cutter module has a cutter blade, for producing X-ray films by cutting a continuous sheet material. The packaging module has packaging robots, for producing a sheet package by packaging the X-ray films stacked on one another. In the sheet package producing system, a first module control unit is incorporated in the cutter module, for controlling the cutter blade. A second module control unit is incorporated in the packaging module, for controlling the packaging robots. A CPU is connected with the first and second module control units removably by a component network, for controlling the cutter module and the packaging module in synchronism.
