A module houses a set of fiber optic interfaces. The apparatus stores hand tools of differing shape and dimension in a compact area in nested, canted storage units shaped to receive the handles of tools. The transmission side lens unit and the reception side lens unit are integrally formed, and a light shield is formed integrally with the lens body between the transmission side lens unit and the reception side lens unit thereof, which is made of a material different from the transmission side lens unit and the reception side lens unit. Furthermore, the controller is configured to operate a notification device that generates a shift notification corresponding to one or more gear shifts based on a continuous operation time of the shifter. The fingers are arranged in a stack with a first finger being disposed at an end of the stack. The turn-on signal of each fluorescent lamp is generated and subsequently delayed by the inverter circuit according to the liquid crystal response in accord with the temperature dependency in each luminescent region.
