PROBLEM TO BE SOLVED: To shorten a time lag from when a start signal is output from a controller to an intelligent driver to when actual action is initiated. SOLUTION: Various pieces of setting data and the like are transmitted in advance from a controller 4 to an intelligent driver 3 through a serial transmission line 51. In the intelligent driver 3, the setting data is written into work RAM 33, and, while a trigger recognition port 35 is monitored, standby operation is performed. The controller 4 outputs a start command to a trigger control port 45, one of I/O ports, with timing with which a shutter is desired to operate. When the intelligent driver 3 receives the start command, it refers to the setting data in the work RAM 33, and starts driving the shutter. |
