PURPOSE: To change quickly an input item, by arraying plural display parts having a film for showing an input item and its holding and moving means, and providing a film centralized holding and moving means for winding in the lump the film to the other end.

CONSTITUTION: An input part 11 is constituted of a display part consisting of a film FM 15-i which moves on a guide plate 9-i (i=1W5) and displays an input items, and an FM holding and moving means consisting of an FM scanning shaft 13-i which winds one end of the FM and moves the FM by rotation. A centralized holding and moving means is constituted of a driving transfer shaft 21-i which is fit-installed to the shaft 13-1 and is coupled with a driving transfer shaft connecting part 19-i, a bevel gear BG 23-i provided on its end part, a BG 17-i engaged with it, a FM scanning shaft 25 which winds in the lump the other end of each moving FM, a driving tranfer shaft 31, and BGs 33, 27 coupled and engaged with it. The BGs 17-i, 27 are coupled with synchronizing rotary shaft 41, the shaft 41 is driven by a pulse motor 39, and they constitute a synchronizing driving control device together with the BGs 17-i, 23-i and the shfts 31, 21-i, then, an input item is changed quickly.
