摘要

The device (1) has a movable index (2) displaced by a driving unit (5), where the index comprises an emitting unit for emitting a spot of light (30) from an end surface of the index. The end surface of the index is arranged opposite to a partially reflecting surface (4), and position of the spot on the reflecting surface indicates information. The spot of light is created by capturing an ambient light ray (3) or a reflecting or luminescent material (27). A surface portion of the emitting unit comprises a reflecting or luminescent material cover.
