An imager comprising is provided having an image-capturing device, a display, and a view angle controller. There is a zoom lens provided, which comprises, in order from its object side, a first lens group G1 having negative refracting power, a second lens group G2 having positive refracting power, and a third lens group G3 having positive refracting power. The ball is controlled by a float on a pivotable lever arm with an end finger which holds the ball up to admit water with the float down and allows the ball to lower onto the seat as the cell fills causing the float to rise to a shutoff level when the cell is filled to a desired level. The readout scrambled version is de-scrambled to recover the SID code word. The wiring pattern is directly connected to the electrode pad and the piercing electrode.
