Abstract

The present invention provides, among other things, an information inputting tool that can be made space-saving and places small constraint on key touch actions. For that purpose, an information inputting tool of the present invention is provided with a reflection portion (11B) provided with a single or a plurality of reflection members (11C) having retroreflectivity, with an attaching gadget (11c, etc.) that attaches said reflection portion to a finger of an operator, and with a change mechanism (11S, 11a₁, etc.) that changes the reflectance distribution of said reflection portion in accordance with a finger pressure applied to the finger end of said finger.
