Claims5
An external illumination apparatus for an optical information reading apparatus, which is used together with the optical information reading apparatus having a communication function with external equipment, the external illumination apparatus comprising:
- a plurality of illumination LEDs;
- a switching device that switches lighting and lighting-out on a basis of each area resulting from dividing the plurality of illumination LEDs into a predetermined plurality of areas;
- a memory storing a lighting pattern defining the area to be lighted;
- a control device that controls the switching device so as to light the illumination LEDs in the area corresponding to the lighting pattern, with reference to the lighting pattern stored in the memory;
- and
- an LED driving device that lights the illumination LEDs permitted to be lighted by the control device, upon receiving an external lighting command trigger.
