Description
また、このとき、電磁アクチュエータのコイル8には通電されていない。ところが、周知のように、このとき、回転子6は、その永久磁石6dの磁極とヨーク7の二つの磁極部との対向配置関係によって反時計方向へ回転するように付勢されており、それによって、駆動ピン6aには、図2において略下方へ移動し、シャッタ羽根2,3を相反する方向へ回転させる力が与えられている。シャッタ羽根2,3が、ストッパ軸1g,1hに接触し、さらに図2のように駆動ピン6aが地板1の孔1aに接触し、その回転を阻止されているため、この状態が維持されている。 At this time, the coil 8 of the electromagnetic actuator is not energized. However, as is well known, at this time, the rotor 6 is biased to rotate counterclockwise by the opposite arrangement relationship between the two magnetic pole portions of the pole and the yoke 7 of the permanent magnets 6d, it Thus, the driving pin 6a is given a force that moves substantially downward in FIG. 2 and rotates the shutter blades 2 and 3 in opposite directions. Shutter blades 2 and 3, the stopper shaft 1g, in contact with 1h, further driving pin 6a as shown in FIG. 2 is in contact with the hole 1a of the base plate 1, therefore being prevented from rotating, the state is maintained Yes.
そのため、回転子6は、時計方向へ回転させられ、駆動ピン6aを、図2において略上方へ移動させていくので、シャッタ羽根2は反時計方向へ回転され、シャッタ羽根3は時計方向へ回転される。それによって、2枚のシャッタ羽根2,3は、開口部1bを閉じていく。 Therefore, the rotor 6 is rotated clockwise, the driving pin 6a, so gradually moved to substantially upward in FIG. 2, the shutter blades 2 are rotated in the counterclockwise direction, the shutter blade 3 to the watch direction It is rotated. Accordingly, the two shutter blades 2 and 3 close the opening 1b.
このようにして、図4に示された状態になると、固体撮像素子に蓄積された電荷が、撮像情報として記憶装置に転送される。そして、その転送が終わると、コイル8に対して上記とは異なり逆方向の電流が供給されるため、回転子6は、反時計方向へ回転させられ、その駆動ピン6aを、図4において略下方へ移動させていく。 In this manner, when the state shown in FIG. 4 is reached, the electric charge accumulated in the solid-state imaging device is transferred to the storage device as imaging information. Then, substantially the the transfer is complete, since the reverse current unlike the is supplied to the coil 8, the rotor 6 is rotated counterclockwise, the driving pin 6a, 4 Move it down.
そのため、シャッタ羽根2、3は、相反する方向へ回転させられ、開口部1bをその略中央部から開放していく。そして、図5のようにシャッタ羽根2、3が開口部1bを全開にすると、図5のように駆動ピン6aは、当接ピン6bと回動リング部材5の孔5aが当接することにより、回転速度を減速されながら回動リング部材5と一体となって回転する。その後、回転子6および羽根2,3は減速されながらも回転を続け、それぞれ地板の孔1a、ストッパ部1e,1fに当接することで停止し、図2の状態に復帰することになる。 Therefore, the shutter blades 2 and 3 are rotated in opposite directions to open the opening 1b from the substantially central portion. When the shutter blade 2 as shown in FIG. 5 is fully opened opening 1b, the drive pin 6a as shown in FIG. 5, by hole 5a of the contact pin 6b and the rotary ring member 5 abuts, It rotates integrally with the rotating ring member 5 while the rotational speed is reduced. Thereafter, the rotor 6 and the blades 2 and 3 continue to rotate while being decelerated, stop by contacting the holes 1a and stoppers 1e and 1f of the base plate, respectively, and return to the state shown in FIG.
次に、本実施形態の作動を説明する。図7は、撮影待機状態を示す模式図である。図6に示したように、回動リング部材5、10が重なった状態で配置されており、紙面奥側が回動リング部材10、手前側が回動リング部材5である。尚、本実施形態の特徴として、回動リング部材10の孔10aは回動リング部材5の孔5aよりも狭くなっている。このとき、電磁アクチュエータのコイルには通電されていないが、実施形態1と同様に、回転子6は、その永久磁石6dの磁極とヨーク7の二つの磁極部との対向配置関係によって反時計方向へ回転するように付勢されており、それによって、駆動ピン6aには、図7において略下方へ移動し、さらに図7のように駆動ピン6aが地板1の孔1aに接触し、その回転を阻止されているため、この状態が維持されている。 Next, the operation of this embodiment will be described. FIG. 7 is a schematic diagram showing a shooting standby state. As shown in FIG. 6, the rotating ring members 5 and 10 are arranged so as to overlap each other. The rear side of the drawing is the rotating ring member 10, and the front side is the rotating ring member 5. As a feature of the present embodiment, the hole 10 a of the rotating ring member 10 is narrower than the hole 5 a of the rotating ring member 5. At this time, although not energized the electromagnetic actuator coil, as in Embodiment 1, the rotor 6 is counterclockwise by opposed relationship with the two magnetic pole portions of the pole and the yoke 7 of the permanent magnets 6d Accordingly, the drive pin 6a moves substantially downward in FIG. 7 , and the drive pin 6a contacts the hole 1a of the main plate 1 as shown in FIG. Since this is blocked, this state is maintained.
