A panel shutter device constructed in such a way that in the process of continuously moving each panel by a lifting shift along guides rails and a lateral shift along a housing rail, a guide rotary member engages or disengages a guide shaft projecting from the side of the panel opposite the driven side. At the time of descending of the shutter curtain, in order to prevent finger pinching as each panel is placed on the succeeding panels sequentially, each panel can be lifted or descended without causing a gap between panels of the shutter curtain by providing the support member suspended by a pivotable connecting chain.
