Abstract: The invention relates to a television contest-entering device for the tamperproof recording and storing of entries in television contests. Such a handy device can be mailed, for example, to all interested televiewers before the progam is broadcast, thus permitting these viewers to participate outside the television studio in a contest where the answers to questions asked in a quiz game, for example, are to be recorded with exact indication of the time at which they are recorded, and preserved in a tamperproof manner, the device then being returned by the contestant to the television station for judgment of the entries.
