<p>The invention relates to a manual device for keeping track of penalties in ice hockey and roller hockey. Both sports involve player penalties whereby the player is removed from the game for a period of time, but, during this time, a minimum number of players must remain on the rink, while a maximum number serves penalties. The slide rule is manually actuated in order to provide information concerning not only the players on the rink, but also sanctioned players still to serve a sanction and sanctioned players serving sanctions. The rule comprises a box, a player scale and a penalty scale. Said scales are moved in response to incidents in the game and viewing windows display the players on the rink, players serving penalties and penalised players awaiting penalty.</p> |
