    摘要: In exposure means comprising, in combination, two shutter blades which also function as the aperture setting blades, a step-motor for displacing the shutter blades stepwise in response to the driving pulse or pulses, and a driving circuit for the step-motor. Slits are cut through the shutter blades so that the relative displacement between the shutter blades may be optically detected in order to control the stepwise rotation of the step-motor, thereby displacing the shutter blades to define the main aperture stepwise; and when the light from a subject reaches a predetermined level, detecting means causes the step-motor to reverse its rotation, thereby closing the shutter blades. The program-controlled shutter in accordance with the present invention is very simple in construction and is free from any erratic operations.

    摘要: A flash apparatus capable of varying the emission angle according to the present invention is characterized in that a light controller provided in front of a reflector for diffusing or condensing supplied light is configured to comprise a diffusion controlling portion having light diffusive action only with respect to a longitudinal direction of a bar-like light source and a condensation controlling portion having condensing action to omnidirectionally condense supplied light. By this, the flash apparatus capable of varying the emission angle can control and restrict prism action at the light controller by diffusing light emitted from the bar-like light source in respect to the longitudinal direction of the bar-like light source even when the bar-like light source and the light controller are close to each other. As a result, unevenness of light distribution (rainbow-like unevenness) based on the prism action at the light controller can be prevented from occurring even in a state on the wide side when the light emitting portion is miniaturized.

    摘要: A cold cathode fluorescent discharge tube is provided having, as an anode standing for one of discharge electrodes, a mercury discharge structure comprising a metal sintered body formed by sintering powder of a high melting point metal such as titanium, with mercury combined with the metal sintered body. The mercury discharge structure is so formed as to contain large amount of mercury and is therefore permitted to have a compact shape in order to obtain a requisite amount of mercury. The cold cathode fluorescent discharge tube permits a sufficient amount of mercury to be sealingly incorporated in the interior of the tube without decreasing the ratio of the effective luminescent length to the total length, having suitability to diameter reduction, and can be produced at low cost.
