PROBLEM TO BE SOLVED: To provide a power supply operation apparatus for a blade that accurately controls ON/OFF of power supply to the blade in response to the operation of an injector lever even when the processing accuracy of the injector lever, positional accuracy concerned with attachment of the injector lever, or the like is not necessarily sufficient. SOLUTION: Whether a tongue 6 formed integrally with the injector lever 3 is intruded into the blade 2 is detected by an optical sensor 4, and only when the optical sensor 4 detects the tongue 6, a power supply control part 5 is driven to allow power supply from a shelf to the blade 2. A switch or a linkage which may perform mechanical operation is made unnecessary, thereby accurately controlling ON/OFF of power supply from the shelf to the blade 2 in response to the operation of the injector lever 3.
