Abstract
Rotational member (310) with plural tactile pins (301) movable up-and-down for displaying characters is rotated by rotation driving means. Elastic O-rings (370) are provided in the rotational member (310) for pressing and holding the pins (301). Actuators (320) brought to contact the pins (301) are provided nearby the rotational member (310) for positioning the pins (301) at desired heights from a tactile surface. Cam (330) brought to contact with the pins (301) is provided also nearby the rotational member (310) for positioning the pins (301) at the reset position or height. Furthermore, selectively actuating means is provided for selectively actuating the actuators (320). Owing to such arrangement, a continuous tactile pin display apparatus can be reduced in size, weight and cost.By providing at least the pins (301) or the rotational member (310) with a photocatalyst, it becomes possible to decompose contaminants, such as bacteria, sweat, oil of the hand and food particles, deposited on the pins or their peripheral portions.
