To prevent light of a lighting device from causing difficulties in operating other devices.

The respective units 2, 3, 4 are housed in one casing, and a person sensor 6 is fitted to the casing. A control part 7 causes a light emitting part 2a to turn on with a predetermined brightness when a display 4a is turned off, and causes the light emitting part 2a to turn on darkly less than with the predetermined brightness when the display 4a is turned on or when the person sensor 6 senses a patient's hand. Thus, when the display 4a is turned off or a patient is not about to operate a call operating part 3a, the light emitting part 2a is turned on with the predetermined brightness so that enough brightness can be secured. On the other hand, when the display 4a is turned on or he is about to operate the call operating part 3a, the light emitting part 2a is turned on darkly less than with the predetermined brightness to prevent the light of the lighting unit 2 from being difficult to see the display 4a and the call operating part 3a.
