Rotational member () with plural tactile pins () movable up-and-down for displaying characters is rotated by rotation driving means. Elastic O-rings () are provided in the rotational member () for pressing and holding the pins (). Actuators () brought to contact the pins () are provided nearby the rotational member () for positioning the pins () at desired heights from a tactile surface. Cam () brought to contact with the pins () is provided also nearby the rotational member () for positioning the pins () at the reset position or height. Furthermore, selectively actuating means is provided for selectively actuating the actuators (). Owing to such arrangement, a continuous tactile pin display apparatus can be reduced in size, weight and cost. By providing at least the pins () or the rotational member () 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.

Tactile pin holding apparatus, tactile pin display apparatus and braille display member

An apparatus for starting an internal combustion engine which comprises: a rope starting device including a rope provided with a knob, a reel around which the rope is wound and a clutch adapted to transmit the rotation of the reel to an engine crank shaft; and a decompression device including a cam adapted to forcibly open an exhaust valve by pushing one end of a valve lever associated with the exhaust valve and a shaft on which said cam is fixed to be biased resiliently and rotatively in one direction, the pushing amount of the end of the valve lever by the cam being set to be smaller than the pushing amount of the same effected by a push rod of a valve actuating mechanism for the exhaust valve. When the end of the valve lever is pushed by the cam, the cam engages the valve lever while keeping the exhaust valve in the opened state, whereas when the push rod pushes the end of the valve lever, the cam is disengaged from the valve lever.
