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 transmission line with both data storage function portable structure thereof includes a cable, a memory module, a Micro USB connector, a cover, a housing and a shell. The memory module and the Micro USB connector are connected to two opposite ends of the cable. The cover covers over the memory module. The housing has a front wall, a rear wall and two side walls which corporately define a receiving chamber. A partition is defined at the center of the receiving chamber and divides the receiving chamber into a first receiving cavity and a second receiving cavity. The memory module and the Micro USB connector are respectively located in the first and second receiving cavities of the housing. The shell encloses the housing.
