Accordingly, each photosensitive portion includes a portion of the semiconductor substrate 40 and a pair of the regions 41 and 42, thus configuring a photodiode. Each of the regions 41 and 42 is in a shape of an approximate triangle, and is formed so that one side of the regions 41 is adjacent to one side of the region 42, and vice versa, in one pixel. A first wire 44 is for electrically connecting the regions 41 on one side in each pixel across a first direction, and is provided extending in the first direction between the pixels. The second wire 47 is for electrically connecting the regions 47 on the other side in each pixel across a second direction, and is provided extending in the second direction between the pixels.

摘要： A signal current I1 that is output from output terminal of semiconductor position detection element is converted to a signal voltage V1 by a current/voltage conversion unit and a signal current I2 that is output from output terminal is converted to a signal voltage V2 by a current/voltage conversion unit. Signal voltages V1 and V2 are compared in magnitude by a comparison circuit and a comparison signal is output so that maximum signal Vmax and minimum signal Vmin are selected. In A/D conversion circuit, the A/D conversion range is set using maximum signal Vmax, and minimum signal Vmin is converted to a digital signal and output. The position of beam incidence on semiconductor position detection element is found by incidence position calculating unit using the comparison signal and digital signal.

摘要： A light-emitting element drive circuit is provided whereby level variation of the drive current can be suppressed. This circuit is provided with a detection circuit 4 that detects the DC current component I6′ of high-frequency current I4 (I5) flowing through a second current mirror circuit 2, and an adjustment circuit 5 that subtracts the DC current component I6′ detected by the detection circuit 4 from the DC current I1 (I7) flowing through line 1B of first current mirror circuit 1. Thus, level variation of the drive current IL′ which represents the superposition of the DC and high-frequency can be suppressed.
