Abstract: A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit board disposed within the longitudinal channel of an elongated housing member having an enclosing cover panel of light-transmitting material. The unit has connector terminals at opposite ends, and the linear array of flashlamps is divided into two groups disposed in opposite halves of the unit, each group of lamps being operated by the connector terminal at the remote end so as to reduce the red-eye photographic effect. The lamp-firing circuitry includes a pair of spaced-apart common circuit conductor runs respectively located on opposite halves of the printed circuit board and on opposite sides of a common surface. An interconnecting jumper, or crossover, between the common circuit runs is provided by means of a conductive staple secured to the circuit board. Two legs of the staple pass through the circuit board and are bent over in contact with respective ones of the common circuit runs, and the center region of the staple is disposed on the opposite side of the board.

Abstract: A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit board disposed within the longitudinal channel of an elongated housing member having an enclosing cover panel of light-transmitting material. The lamp firing circuitry includes a pair of spaced-apart common circuit conductor runs respectively located on opposite halves of the printed circuit board. The circuit board is secured to the rear wall of the housing channel by means of a staple having two legs extending through both the housing wall and circuit board, with the center region of the staple being disposed on the exterior of the channel wall. The staple legs are bent over in contact with respective ones of the common circuit runs to provide an interconnecting jumper therebetween and extend electrical ground to the exterior of the unit. The bent staple legs are also outwardly directed to contact a conductive-reflective coating on the channel sidewalls, thereby grounding the coating to provide an electrostatic shield.

Abstract: A mechanism for activating a plurality of flashlamps in a flashlamp article (e.g., MAGICUBE) in response to external actuation (e.g., the opening or closing of a door) thereof. To prevent accidental actuation, the mechanism includes a safety device in the form of an elongated pin which inserts within a pair of aligned openings within the mechanism to positively engage and retain the mechanism's movable activator. In one embodiment, the pin is also attached via a cord to the mechanism's spherical ball engagement member which causes movement of the activator.

Abstract: A photoflash device circuit board assembly including a dielectric substrate, switching element, and conductive member. The switching element and conductive member are pressed (e.g., die-stamped) within the substrate. The substrate is provided with a flexure means to permit it to flex during pressing such that the switching element will not be severed. A photoflash device including the circuit board assembly and a light-transmitting housing and an electrically activated flashlamp is also described.
