Abstract
An optical reader which is compatible with every environment irrespective of installation and usage environments, thereby enabling uniform manufacturing, satisfactory reading reliance, and operative safety and user-friendliness. The optical unit is mounted on the stage, and there is provided an inclination apparatus which inclines the stage at a desired angle. Thereby, without changing a preset optimal scanning pattern, only its emitting direction becomes changeable freely.
Claims3
A scanning method comprising the steps of:
- generating a predetermined scanning pattern to read out an optically readable medium;
- changing an emitting direction of the predetermined scanning pattern to a desired direction while maintaining the predetermined pattern;
- emitting the predetermined scanning pattern to the desired direction;
- reading out light reflected from the medium based on the predetermined pattern;
- detecting a position of the medium;
- and
- determining automatically the desired direction based on the position of the medium which has been detected.
