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.
