The present invention maximizes modeling results for targeted marketing within a specific working interval so that lift within the working interval is higher than that obtained using traditional modeling methods. A lattice tower type arm is hinged to the frame of the turret and movable between substantially raised and inclined positions. A hinged cover further defines a cable pathway for managing the cable. In the operation of reading the pixel signals from the th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line by the switching operation in a switching circuit.
