发明名称 LIGHT EMITTING DEVICE ATTACHED TO IMAGE PICKUP APPARATUS
摘要 A mechanism which makes it possible to space-efficiently arrange electrical components and a circuit board in a light emitting device. The light emitting device includes a light emission section and a circuit board disposed in a manner extending in a direction intersecting with an emission surface of the light emission section. A first flash circuit including a booster circuit, a second flash circuit including a high voltage circuit for causing the light emission section to emit light, and a third flash circuit including a control circuit for a digital system are mounted on the circuit board, and the third flash circuit is disposed at a location more remote from the light emission section than the first flash circuit and the second flash circuit are.
