Abstract
A cap covering a light-emitting element attached to the distal end of an indicator is held by a sliding member, and is slidably attached axially along the indicator. By pressing/separating the cap against/from a coordinate input surface, a tact switch operates interlockingly with the cap to switch driving control of the light-emitting element. For example, the light-emitting element is driven by pressing the cap, and driving of the light-emitting element is stopped by separating the cap. Since the cap covers the light-emitting element, the light-emitting element can be prevented from being worn and scratched. Driving control of the light-emitting element need not be additionally switched, resulting in high operability.
