Abstract

In the work device that has a self-holding circuit () maintaining power supply from a power supply circuit () by output from a microcomputer () and has a structure in which stopping output to the self-holding circuit () causes interruption of power supply from the power supply circuit () to the microcomputer (), the firmware of the microcomputer () is made to be rewritable and a power holding unit (condenser C) for temporarily continuing power supply to the microcomputer () is provided, thereby realizing a so-called 'off-delay timer function' for restarting the microcomputer (). This configuration enables maintenance of power to the microcomputer () after update of the firmware even in a work device that cannot be restarted once power has been turned off unless trigger operation is performed, thereby enabling automatic restart of the microcomputerafter resetting is enabled.
