ABSTRACT:
Image bearing panels with interleaved strips are slidably carried by a sign base. A motor drives a crank and reciprocating arm with the arm end sequentially engageable with an abutment on each panel to shift the panel and expose the panel image. An obstruction is positionable at the completion of the last panel shifted which causes the arm to move out of its reciprocating path to engage and actuate linkage acting on the panels to collectively reposition the panels preparatory to the start of a viewing sequence.
