Abstract
In an operation-mode indicating system, a first light emitting device is located within a peripheral visual field of an operator and is controllably connected to a controller. The peripheral visual field is defined around a center visual field of the operator while the operator is looking at a predetermined site. A body support apparatus is capable of performing an operation to the predetermined site. The controller controls the first light emitting device to emit first light in a first operation mode of the body support apparatus and second light in a second operation mode of the body support apparatus. The first light and the second light are visually distinguishable from each other.
