Claim 1

In an electronic flash unit including a housing and reflector, comprising in combination: a rib on to said housing, said reflector having an axis of rotation which substantially coincides with said rib, said reflector being movable between first and second arrestable positions, means for arresting the reflector in at least said first and said second arrestable position, said reflector being capable of emitting a flash toward a subject in each of said positions, said reflector being adapted to receive an elongated electronic flashlamp, the axis of the lamp being oriented at right angles to the axis of rotation of the reflector and wherein said housing is of a substantially rectangular shape, said housing also including a cavity in the wall of the housing which faces the subject to be illuminated, said cavity receiving the reflector in said first of said arrestable positions said reflector emitting direct illumination toward the subject in a direction substantially normal to said wall of the housing when in said first position, the reflector being rotatable about the uppermost edge of said cavity which coincides with said rib, said reflector also being arrestable in said second position rotated about from 80* to 90* from said first arrestable position in a direction away from the housing, said reflection emitting indirect illumination to a subject when in said second position.
