摘要： In a CMOS image sensor, current leakage after a series of noise removing operations has been completed is suppressed in a read operation for each horizontal line, thereby suppressing image noise occurring on the output display screen of the image sensor. There are provided signal storage regions for storing the signals read from the unit cells in the same row selected in the imaging area onto vertical signal lines and horizontal select transistors for sequentially selecting and reading the signals stored in the individual signal storage regions and transferring them to read horizontal signal lines. At least in the period during which the signals are read from the signal storage regions, one of the drain and source of the transistor electrically connected to the signal path between the vertical signal line and horizontal signal line is biased in the reverse direction with respect to the substrate region. Two adjacent ones of the horizontal select transistors form a pair. The horizontal select transistors in each pair share one of the source/drain regions so as to be connected to the horizontal signal line in common, and the others of the source/drain regions are connected to the vertical signal line individually.

The smoke detection device the sampling tube forms a lead-in tube and suctions air through the sampling tube in substantially a straight line. The lead-in tube is formed with a smoke sensor unit to detect smoke particles contained in the air. The aspirator comprises a rotating part which forms an actuator mechanism that discharges the air. The central axis of the lead-in tube and the rotational axis of the actuator mechanism of the aspirator are substantially on the same axis. The sampling tube-type smoke detector is provided to reduce pressure loss in the airflow traveling from the smoke detection device to the aspirator and to supply a low cost, compact smoke detection device driven by a small-sized fan.
