Abstract: There is provided an optical engine for a navigation device including a first light source, a second light source, a lens, a barrier structure and an image sensor. The barrier structure has a first space for containing the first light source, a second space for containing the lens and a third space for containing the second light source and the image sensor. The reflected light associated with the first light source propagates to the image sensor via the lens in the second space. The reflected light associated with the second light source propagates to the image sensor via the third space without passing through the lens in the second space.

Abstract: There is provided a capacitive joystick device including a substrate, a fixed plate, a movable member, a plurality of elastic elements, a cone and an operation stick. The substrate includes a ground region and a capacitance sensing region. The fixed plate includes a first opening. The movable member includes a second opening. The elastic elements are symmetrically disposed between the fixed plate and the movable member. The cone is disposed between the movable member and the substrate, and includes a base, a vertex and a lateral surface. The base presses against the movable member. The vertex is disposed on the ground region of the substrate. The lateral surface is aligned with the capacitance sensing region of the substrate. The operation stick extends from the base of the cone and passes through the first opening and the second opening.

Abstract: There is provided a bottom cover for being covered on an optical system. The bottom cover is attached in front of the optical engine. The bottom cover has a bottom surface for facing a working surface when the optical system is moving on the working surface, a first opening for emission light of the optical engine to go through and a second opening for reflected light from the working surface to go through. The bottom cover is further formed with guiding protrusions protruded out from the bottom surface toward the working surface and surrounding at least the second opening to guide soft materials on the working surface to away from the second opening.
