Abstract
When directing a slit-like image information light to an imaging lens through a condensing lens, the refractive power of the condensing lens is made to differ between the lengthwise direction and the slit width direction of the slit light beam, whereby the light is effectively received without the read image being deteriorated. Also, when a convergent light transmitting member array is used as the imaging lens, the refractive power of the condensing lens is made to differ between the lengthwise direction of the array and a direction orthogonal to the lengthwise direction of the array, whereby the light is effectively received without the read image being deteriorated.
