A storage box includes a box body, M*N infrared sensors and light emitting diodes(LEDs), a logic unit and a processing unit. The logic unit includes a plurality of three-state output latches, wherein M*N generates M*N driving signals based on M first control signals and N input and output signals to control the LEDs to emit light. The other M*N three-state output latches output N of M*N sensing signals of the infrared sensors to the N input and output signals based on M second control signals. The processing unit generates the first control signals and the second control signals, and obtains the M*N sensing signals by the N input and output signals at different time, and further, generated the M*N driving signals by the N input and output signals at different time based on the M*N sensing signals.一種收納盒包含一盒體、M*N個紅外線感測器與發光二極體、一邏輯單元及一處理單元。該邏輯單元包括多個三態輸出栓鎖器，其中M*N個是根據M個第一控制信號及N個輸出入信號，產生M*N個驅動信號以控制該等發光二極體發光，另外M*N個三態輸出栓鎖器根據M個第二控制信號，將該等紅外線感測器的M*N個感測信號之其中N個輪流輸出至該N個輸出入信號。該處理單元產生該等第一控制信號及該等第二控制信號，且在不同時間點還藉由該N個輸出入信號獲得該M*N個感測信號，進而根據該M*N個感測信號在不同時間點藉由該N個輸出入信號，產生該M*N個驅動信號。
