摘要： To solve an uneven light quantity caused in a case where a light guide plate, in which light from a spot light source such as an LED enters an surface, changes by 90 degrees and exits the light to the outside, is used as a backlight. The light guide plate of the invention includes a light flux unifying region. The light flux unifying region has an incident surface, a first surface, and an exit surface. Light fluxes emitted from a light source enter the incident surface. The first surface is almost perpendicular to the incident surface and the intensity distribution of the light fluxes having entered is unified at the first surface. The exit surface is disposed almost parallel with the incident surface and the unified light fluxes exit from the exit surface. A boundary line between the incident surface and the first surface has a zigzag surface.

摘要： A blade type focal plane shutter wherein an auxiliary arm is always biased with a spring so that backlashes at pivotably connecting points between a driving arm and shutter blades and between the auxiliary arm and shutter blades may not have a bad influence on the shutter opening and closing motions. This focal plane shutter is provided with a braking lever which can catch a closing driving lever to prevent a bound from being caused when the motion of the shutter blades for exposure ends.
