Abstract:
An erecting equal-magnification lens array plate includes a first lens array plate and a second lens array plate provided opposite to each other, each of the first and second lens array plates being formed with a plurality of lenses on both sides thereof. The first lens array plate is provided with a first lens-to-lens distance determining part. The second lens array plate is provided with a second lens-to-lens distance determining part. The distance between opposite lenses is determined by the contact between the first lens-to-lens distance determining part and the second lens-to-lens distance determining part.
