A strobe pop-up apparatus in which a strobe body is moved between a retracted position and a projection position, includes rotational levers which are pivoted at one end to the sides of a front portion of the strobe body and which are pivoted at their opposite ends to supporting members, and a cam guide mechanism having cam grooves and pins fitted in the cam grooves, between the sides of a rear portion of the strobe body and the supporting members, for guiding the movement of the strobe body between the retracted position and the projected position in accordance with the rotation of the rotational lever. The cam grooves are provided, on their terminal ends adjacent to the projected position of the strobe body, with archwise cam groove portions which extend along a circle having a center on an imaginary line parallel with the rotational levers when located in the vicinity of the projected position and having a radius that is the same as the rotational movement of the rotational lever.
