<P>PROBLEM TO BE SOLVED: To allow a current day to be quickly found out, enabling recognition of the position of a week or a month, upon covering past days with a transparent color film, though only a × mark is put on the past day and a mark is put on the current day on an event blackboard and consequently this day and a day of the week cannot be quickly found, which is a fault. <P>SOLUTION: A transparent color film winding implement and a transparent film winding implement are attached to the event blackboard to cover the past days and the days of the week with a transparent color film. In this case, when the transparent film is wound, the transparent color film is pulled to cover the past days and the days of the week. Thereby today can be quickly recognized. The winding implements are prevented from automatically rotating. A magnet, a double-faced tape or the like are attached to a rear surface of the winding implement to enable the winding implement to be adhered to the event blackboard in a simple manner. <P>COPYRIGHT: (C)2012,JPO&INPIT |
