Abstract

PURPOSE: To surely prevent a display plate from being stopped in a state where it is hardly viewed by providing a driving control means for stopping driving in the case both a stop priority judging signal and a stop signal are inputted at the time of stopping a device for circularly displaying many display plates. CONSTITUTION: The display plates 8 are successively displayed on the window W of a main body 2 by a moving means constituted of a motor 14, a sprocket 6 and a chain 7 controlled by a controller 4 and a feeding means driven by a motor 21. A limit switch 24 which is turned on to drive the motor 21 only while the plate 8 is fed from a standby position to a display position constitutes the stop priority judging means together with a limit switch 27 which is turned off to stop the motor 14 when the plate 8 comes to the display position. Even when a customer operates a switch SA to input the stop signal in the case either the switch 24 or 27 is turned on, operation is continued until both of them are turned off. Even though a plug socket is pulled out, a warning is issued by a built-in battery so as to accelerate the correction of a stopping position.
