Claims

[Scope of utility model registration request]

Stack the mark sheets before reading (hopper section and
a sheet conveyance unit that conveys the mark sheets one by one from the hopper unit to the mark reading unit; a means for reading the mark sheets conveyed in the mark reading unit and stacking the read mark sheets in a stacker unit;
A light source that projects a light beam onto the surface of the top sheet of the mark sheets stacked in this stacker section, and a light source that projects a light beam onto the surface of the top sheet when the surface of the top sheet reaches a predetermined position, the light beam reflected by the surface is incident. What is claimed is: 1. A mark sheet reading device comprising: a light-receiving element provided at a position; and a stacker-full detection circuit that outputs a stacker-full signal when the reflected light beam is incident on the light-receiving element.
