Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A hanging frame assembly includes a support seat made of metal and having a bottom wall forming a substantially C-shaped ring, two angularly spaced-apart sidewalls extending upwardly from an outer peripheral end of the bottom wall, two wing plates bending outwardly and respectively from top ends of the sidewalls, and a plurality of angularly spaced-apart positioning ribs extending upwardly from an inner peripheral end of the bottom wall. A buffer piece made of rubber is mounted on the bottom wall, forms a substantially C-shaped ring, and has a plurality of angularly spaced-apart positioning grooves receiving fittingly and respectively the positioning ribs.

Abstract: A hollow hanging rod includes a tubular section having an axial hole extending through a top open-end thereof, and a bowl-shaped section extending upwardly, curvedly, and expandedly from the top open-end of the tubular section and having a top open-end distal from the top open-end of the tubular section, a bottom open-end connected to the top open-end of the tubular section, and a surrounding wall connected between the top and bottom open-ends of the bowl-shaped section and defining an interior space with a width that gradually increases from the bottom to the top open-ends of the bowl-shaped section. The top open-end of the bowl-shaped section defines a single top opening having a width larger than that of the axial hole. The interior space opens at the single top opening. The tubular and bowl-shaped sections are made of metal, and are formed integrally as a one-piece body.
