1. An optical reading device, comprising:
- optical reading means for optically reading bar codes including a time bar code indicating a limit time, correct answer bar codes indicating correct answers, and selected answer bar codes;
time measuring means for measuring time data; and
control means for preventing said optical reading means from optically reading when the time data measured by said time measuring means has reached the limit time indicated by the time bar code read by said optical reading means.

Abstract
In an electronic reading device, the bar code of the limit time set for a question to be solved is read with a bar code reader. This limit time data is set on a sub tract timer, which decrements as time passes. The bar code reader is also designed to read the answer bar code for the question. During the limit time, answer bar codes can be read with the bar code reader. Beyond the limit time, however, those codes cannot be read. This encourages the learner to solve the questions within the limit time, enhancing the learning effects.
