SHUTTER APPARATUS FOR CAMERA

摘要

A shutter apparatus for a camera is provided to improve operational speed of a shutter by rotating a shutter driving unit using an electromagnet and a permanent magnet so that attractive force and repulsive force are simultaneously applied to the shutter driving unit. A shutter apparatus(1) for a camera comprises a base plate(10) having a large light transmission hole(11), a first shutter(20), a second shutter(30), a shutter driving unit(50), and a shutter electromagnet(60) installed at two sides of the shutter permanent magnet. The shutter driving unit is rotatably installed at a side of the base plate and includes a shutter permanent magnet(57). The first and second shutters rotate on a shutter rotation shaft while overlapping an upper surface of the base plate to open/close the large light transmission hole. The shutter driving unit allows the first and second shutters to rotate on the shutter rotation shaft.
