Claims

[Scope of utility model registration request]

A control unit, a manual/automatic switching circuit, a microswitch that is turned on and off by opening and closing the darkroom door, and operates with a stroke sufficiently smaller than the size of the door, and one or two lights that are controlled by these. The control unit takes in an external power supply, and has a micro switch circuit connected to the power supply lines, an automatic power supply circuit and a manual power supply circuit for the lighting power supply, and further includes: The micro switch circuit includes a main switch, a micro switch, and a timer relay connected in series, and the automatic power supply circuit connects one end of the lighting device via a switch that is switched directly or indirectly by the timer relay. The manual power supply circuit is configured to supply power to one end of the lighting device through a manual power supply switch that responds by maintaining an opening/closing relationship opposite to that of the main switch between the power source and the lighting device. The manual switching circuit further includes a manual/automatic switching switch connected in series with the other end of the lighting device, and a lighting selection switch provided between the manual side line and the power line. A blinking control device for external lighting in a darkroom, characterized in that:
