촬영시, 사용자는 스탠바이 조작부(4)의 조작을 수행하고, 이에 따라 오토 포커스 촬상부(21)가 자동 포커싱 동작을 수행하며, 발광부(3)의 준비가 완료되고, 리니어 모터 기구(30)에 의해 피사체와의 이격 거리에 대응하는 위치에 가동 렌즈(33)가 이동한다. 이후 사용자가 셔터 조작부(41)의 조작을 한다.At the time of shooting, the user performs the operation of the standby operation unit 4, and thus the auto focus imaging unit 21 performs the auto focusing operation, the preparation of the light emitting unit 3 is completed, and the linear motor mechanism 30 The movable lens 33 is moved to a position corresponding to the separation distance from the subject. After that, the user operates the shutter operation unit 41.

발광부(3)의 몸체(31)에는 피사체측 고정 렌즈(32), 가동 렌즈(33) 및 LED 소자(37)를 구비하고, 상기와 같이 리니어 모터 기구(30)에 의해서 가동 렌즈(33)를 이동시키게 된다.The body 31 of the light emitting portion 3 includes a subject-side fixed lens 32, a movable lens 33, and an LED element 37, and the movable lens 33 by the linear motor mechanism 30 as described above. Will be moved.

가동 렌즈(33)는 렌즈 홀더(36)에 유지되고, 상기 렌즈 홀더(36)에는 구동 코일(35)이 일체적으로 구비되어 있으며, 이 구동 코일(35)에 대응하는 몸체(31)의 내측에 마그넷(34)이 고정되어 있다.The movable lens 33 is held in the lens holder 36, and the lens holder 36 is integrally provided with a drive coil 35, and is inward of the body 31 corresponding to the drive coil 35. The magnet 34 is fixed to it.

리니어 모터 기구(30)에서는 가동 렌즈(33)의 이동을 위해, 구동 코일(35)에 전류를 공급하게 되고, 가동 렌즈(33)는 광축을 따라 피사체측 고정 렌즈(32)의 방향으로 이동하게 된다. 여기서 가동 렌즈(33)의 이동량은 구동 코일(35)에 공급되는 전류량 또는 전류 공급 시간에 비례하여 결정된다.In the linear motor mechanism 30, the current is supplied to the driving coil 35 to move the movable lens 33, and the movable lens 33 moves in the direction of the subject-side fixed lens 32 along the optical axis. do. The movement amount of the movable lens 33 is determined in proportion to the amount of current supplied to the drive coil 35 or the current supply time.

LED 소자(37)로부터 광속은 가동 렌즈(33)를 거쳐 피사체측 고정 렌즈(32)의 전방으로 투사된다. The light beam from the LED element 37 is projected to the front of the subject-side fixed lens 32 via the movable lens 33.

이 상태에서 광속은 도 3 내지 도 4에서 나타낸 것과 같이, 광투사각(W)이 되고, 가까운 피사체를 촬영하는 경우에는 플래시 효과가 있다. 즉, 근거리 촬영시에는 가동 렌즈(33)가 고정 렌즈(32)에 근접하게 이동하게 되는 것이다.In this state, the light beam becomes the light projection angle W, as shown in Figs. 3 to 4, and there is a flash effect when photographing a close subject. In other words, the moving lens 33 moves close to the fixed lens 32 when the near field photographing is performed.

한편, 가동 렌즈(33)가 LED 소자(37)의 가까이에 이동하면, 광속은 도 3 내지 도 4에 나타낸 것과 같이 집광투사각(Z)이 되고, 비교적 원경의 촬영에 적합하게 된다. 즉, 원거리 촬영시에는 가동 렌즈(33)가 LED 소자(37)에 근접하게 이동하게 되는 것이다.On the other hand, when the movable lens 33 moves near the LED element 37, the luminous flux becomes the condensed projection angle Z as shown in Figs. 3 to 4, and is suitable for relatively far-field imaging. In other words, during the long distance shooting, the movable lens 33 moves close to the LED element 37.

이러한 가동 렌즈(33)의 제어는 오토 포커스 촬상부(21)의 출력 신호에 근거하여 제어부(22)를 통해서 발광부(3)의 리니어 모터의 구동을 제어하도록 구성되어 있기 때문에, 피사체의 이격 거리에 대응한 플래시 조명이 가능하다.Since the control of the movable lens 33 is configured to control the driving of the linear motor of the light emitting unit 3 through the control unit 22 based on the output signal of the auto focus imaging unit 21, the distance between the subjects. Flash lighting corresponding to this is possible.
