A preamplifier for a receiver is provided to receive light emitted from an external transmitter through plural small light receiving units instead of a light receiving unit, thereby reducing the size of the preamplifier for the receiver and increasing the light receiving rate. A preamplifier for a receiver comprises plural light receiving units(110), a PCB(Printed Circuit Board), and an IC(Integrated Circuit). The plural light receiving units receive light emitted from a remote transmitter and output electric signals based on the received light. The PCB outputs a control signal for controlling a device on the basis of the outputted electric signals. The IC receives the electric signals outputted from the plural light receiving units, and amplifies and outputs the received electric signals. |
