Abstract: The present disclosure relates to the field of display technology, and in particular relates to a light shielding structure and a laser device. The light shielding structure comprises a first light shielding plate group and a second light shielding plate group, each of the first light shielding plate group and the second light shielding plate group comprises at least one light shielding plate, and the at least one light shielding plate can be moved relatively for forming at least two light transmitting regions. The light shielding structure can realize partial scanning of multiple target regions at a time, thereby saving production time, increasing production efficiency, saving water and electricity and other resources, and prolonging the laser lifetime.

Abstract: A flash camera has a single-piece shutter-opening/closing and shutter-flash synchronization driver that translates in one direction to pivot a pair of shutter blades away from one another and simultaneously push a movable switch contact of a normally open shutter-flash synchronization switch to close the switch. Then, the movable switch contact is spring-urged to move the switch contact to reopen the shutter-flash synchronization switch and push the single-piece driver in a reverse direction to move the blades towards one another. Movement of the blades away from and towards one another uncovers and recovers an exposure aperture to take a picture.

Abstract: In a camera, a dual-blade shutter has a pair of shutter blades supported for opening and closing movement to uncover and re-cover an exposure aperture, and a shutter driver that projects into respective overlapping slots in the shutter blades and is supported for shutter opening and closing movement. A high impact striker is movable against a strike portion on the shutter driver to initiate shutter opening movement of the shutter driver, then moves beyond the strike portion, and is returnable past the strike tab to be reset. A fixed post projects into an elongate slot in the shutter driver to support the shutter driver for shutter opening and closing movement and to allow the high impact striker to shift the shutter driver out of the way of the high impact striker so that the high impact striker can be returned past the strike tab without causing the shutter blades to be moved open.

Abstract: A lens shutter system has an inner drive ring which is rotated by a drive motor and an outer drive ring which is rotated by the drive motor. A plurality of shutter blades of the lens shutter system are driven through drive pins of the inner drive ring and drive pins of the outer drive ring so as to be opened and closed or are rotatably supported by the respective pins of the rings. Upon shutter opening, only the inner drive ring is driven clockwise to open the shutter blades. Upon shutter closing, only the outer drive ring is similarly driven clockwise to close the shutter blades. As mentioned above, upon switching between shutter opening mode and shutter closing mode, the direction of rotation of the inner and outer drive rings is not changed. Thus, the shutter operation can be performed at high speed.

Abstract: A sector blade driving device includes a plurality of sector blades which define an adjustable photographic aperture, and a cylindrical member which surrounds the periphery of the sector blades to prevent harmful light from entering the photographic aperture from outside of the sector blade driving device. At least part of the cylindrical member which the sector blades press against when the plurality of sector blades are fully opened is made of a resilient material.

Abstract: A digital camera, which includes an optical module for capturing an image, angle detecting sensor means for detecting the angle of the digital camera when capturing an image, and a photo processing module, which controls the operation of the optical module to adjust exposure, focusing, and field depth when capturing an image, converts captured image into a digital image signal, and rotates the picture frame of the digital image signal thus obtained into an image storage format subject to the camera angle detected by the angle detecting sensor means.

Abstract: A shutter mechanism comprising an aperture through which ambient light is passed to cause a film exposure, a pair of shutter blades supported for pivotal opening movement in opposite opening directions away from one another to uncover the aperture to permit ambient light to pass through the aperture and for pivotal closing movement in return closing directions towards one another to re-cover the aperture and supported to allow them to be pivoted simultaneously in the same direction to cause accidental shutter opening when a physical shock is applied to the shutter blades in the opening direction of one of the shutter blades, is characterized in that each one of the shutter blades completely covers the aperture in order that both of the shutter blades must be removed from the aperture to uncover the aperture to permit ambient light to pass through the aperture, and a single fixed stop is positioned between the shutter blades to prevent either one of the shutter blades from pivoting in the same direction as the

Abstract: In a lens-fitted photographic film unit, a connection lever makes one reciprocating movement when struck by a shutter actuating lever. The reciprocating movement of the connection lever is transmitted to a crank lever to a pair of shutter blades to cause the shutter blades to open and then close a shutter aperture. The connection lever is coupled to the crank lever through a connection pin and a cam slot. The cam slot has an actuating portion and a keeping portion. While the connection pin moves along the actuating portion, the movement of the connection lever is transmitted to the shutter blades through the crank lever to open and close the shutter aperture. While the connection pin moves along the keeping portion, the movement of the connection lever is not transmitted to the shutter blades so that the shutter blades are kept in the opened position.

Abstract: A blade mechanism includes a driving ring. At least two blades each have a pivot, a driving pin and an opening. The pivot of one blade is placed between the pivot and the driving pin of the other blade. The blades are rotated around the pivots by the driving ring. The opening is formed in the blades so as not to block the rotation of the other blades.
