CA 2678785

Shield means are provided for use on data input apparatus. The shield means includes a housing or frame with at least one channel defined therethrough. The at least one channel has a first end and a second end and is arranged such that a user can view the first channel end in a first position when the user is looking through the second channel end and the user's line of vision is substantially parallel with the longitudinal axis of said channel, thereby allowing data and/or data input means associated with or below the first channel end to be viewed by the user in the first position. The view of the first channel end is substantially obscured or shielded from the user in at least a second position when the user's line of vision is at an acute angle to said channel longitudinal axis.

L'invention concerne des moyens de protection utilisés sur un appareil d'entrée de données. Lesdits moyens comprennent un logement ou un cadre dans lequel au moins un canal est défini. Ledit canal comprend une première et une seconde extrémité, et est agencé de sorte qu'un utilisateur peut visualiser la première extrémité de canal dans une première position lorsqu'il regarde à travers la seconde extrémité de canal, la ligne de vision de l'utilisateur étant sensiblement parallèle à l'axe longitudinal du canal, ce qui lui permet de visualiser des données et/ou les moyens d'entrée de données associés la première extrémité du canal ou placée en-dessous de cette dernière dans la première position. La visualisation de la première extrémité de canal est sensiblement obscurcie ou protégée de l'utilisateur dans au moins une seconde position lorsque sa ligne de vision forme un angle aigu avec l'axe longitudinal du canal.
