| 摘要 | PURPOSE:To use only one kind of character wheel by providing on the surface of the character wheel two kinds of display by turns with their directions opposed. CONSTITUTION:On flexible printed board 1', slide electrode surfaces with pairs of a common electrode and independent electrode are printed zigzag and for every pair of slide electrodes, hole 15 is made. On character wheel 10', characters are provided, opposing in direction, by turns and when character wheel 10' is fitted upside down, only the characters whose attitudes are normal can be seen through hole 15 on board 1'. In assembling, board 1' is bent at a prescribed interval to locate hole 15 on the surface and on the opposite surface of the slide electrode, rigid board 6 is fixed. Then, character wheel 10' is provided in the gap. In this case, character wheel 10' is so arranged that while movable contacts 11 and 12 slide on contacts, only characters whose attitudes are normal can be seen through hole 15 when character wheel 10 shifts in turning position momentarily. | ||||||
