A linear image sensor has a plurality of photo-electric conversion elements (S2n, S2n+1 ...) for detecting image information, a corresponding plurality of switching elements (SW2n, SW2n+1 ...), each for reading out an image detection signal from a respective one of the photo-electric conversion elements, and a scanning circuit (SC) for sequentially driving the switching elements. A first common signal line (SL1) is arranged to deliver image detection signals from odd numbered ones of the switching elements to a signal output (SIG}, and a second common signal line (SL2) is arranged to deliver image detection signals from even numbered ones of the switching elements to the signal output. A first re-set gate (RG1) connected to the first common signal line is operable to re-set the odd numbered photo-electric conversion elements through the associated switching elements, and a second re-set gate (RG2) connected to the second common signal line is arranged to re-set the even numbered photo-electric conversion elements through the associated switching elements. |
