Abstract

PURPOSE:To make uniform the reflection light from information such as characters recorded on the character line of a form, by providing a low-reflection region in the center of the inside face of the light restricting case and by providing a high-reflection region around this region. CONSTITUTION:The center surrounding slit 13 of the upper inside face of lamp house 11 is formed as a low-reflection region, and low-reflection black light shield paper 14a is spread. The other part of the inside face is formed as a high-reflection region, and high-reflection white coating film 14b is provided. Carried form 3 is so illuminated that the center of the character line of form 3 becomes darker than the part around it by function of the low-reflection region and the high-reflection region.
