Abstract: A semiconductor device includes a first trans-impedance amplifier, a second trans-impedance amplifier, a peak hold circuit, a comparator and a threshold current setting circuit. The first trans-impedance amplifier converts a first current signal generated by a first photodiode, into which an optical signal is input, into a first voltage signal. The second trans-impedance amplifier converts a second current signal generated by a second photodiode, to which an optical signal is blocked, into a second voltage signal. The peak hold circuit holds the peak value of the first voltage signal. The comparator outputs a pulse on the basis of the first and second voltage signals. The threshold current setting circuit draws out a threshold current.

Abstract: A dual-slope light guide includes a first surface, a second surface and a curved surface. The first surface has first reflecting structures. The second surface, connected to the first surface, has second reflecting structures. An included angle between the first surface and the second surface is unequal to 180 degrees. The curved surface connects the first surface to the second surface. The first surface, the second surface and the curved surface extend from a first end of the light guide to a second end of the light guide. A light beam incident to the first end of the light guide is reflected and converted by the first reflecting structure and the second reflecting structure into linear light emitted from the curved surface. A light source module and an optical assembly for a scanner are also disclosed.

Abstract: An optical scanning device with a dustproof function includes a shell defining a first receiving room and a second receiving room communicating with the first receiving room through an open window defined on the shell for scanning light beams passing therethrough. An optical scanning module is mounted in the first receiving room. A glass platform is located on the second receiving room at a position facing the open window for insulating the first receiving room from the outside of the shell. A correcting plate is stuck on the bottom of the glass platform. Such structure of the optical scanning device enables the glass platform to be firstly assembled with the shell in a dustless chamber, which prevents the suspending dust from falling in the first receiving room and attaching to the optical scanning module during the subsequent assembly process and ensures the scanning quality of the optical scanning device.
