Electronic endoscope apparatus
An electronic endoscope apparatus includes an endoscope light source unit for making illumination light from a light source incident on an incident end face of a light guide of a scope which is detachably connected to a processor, the endoscope light source unit being built in the processor; a main switch for turning ON the processor; a scope lock lever for activating a lock mechanism for preventing the connected scope from coming off the processor; a light source switch for turning ON and OFF the endoscope light source unit; and a controller for turning ON the endoscope light source unit when one of the main switch and the scope lock lever is operated before the light source switch is operated while the endoscope light source unit is OFF.
1. An electronic endoscope apparatus comprising:
an endoscope light source unit for making illumination light from a light source incident on an incident end face of a light guide of a scope which is detachably connected to a processor, the endoscope light source unit being built in said processor;
a main switch for turning ON said processor;
a scope lock lever for activating a lock mechanism for preventing said connected scope from coming off said processor;
a light source switch for turning ON and OFF said endoscope light source unit; and
a controller for turning ON said endoscope light source unit when said scope lock lever is operated in a locked state before said light source switch is operated while the endoscope light source unit is OFF.
2. The electronic endoscope apparatus according to claim 1 , wherein said processor comprises a scope lock switch for detecting whether said scope lock lever is in a locked state;
where said controller turns ON said endoscope light source unit when said scope lock switch detects said locked state.
3. The electronic endoscope apparatus according to claim 2 , wherein said controller selects one of said main switch, said scope lock switch, and said light source switch as a condition for turning ON said endoscope light source unit, so that said controller turns ON said endoscope light source unit when said one of said main switch, said scope lock switch, and said light source switch is turned ON.
4. The electronic endoscope apparatus according to claim 2 , wherein said controller selects said main switch as a condition for turning ON said endoscope light source unit, so that said controller turns ON said endoscope light when said main switch is turned ON.
5. The electronic endoscope apparatus according to claim 2 , wherein said controller selects said scope lock switch as a condition for turning ON said endoscope light source unit, so that said controller turns ON said endoscope light when said scope lock switch is operated in a locked state.
6. The electronic endoscope apparatus according to claim 5 , wherein while said scope lock switch is not in said locked state, said controller turns ON said endoscope light when said light source switch is turned ON.
7. The electronic endoscope apparatus according to claim 1 , wherein said controller turns OFF said endoscope light source unit when one of said main switch and said light source switch is turned OFF.
