发明名称 Daily calendar apparatus for the poor sighted
摘要 An apparatus for displaying daily calendar information. It comprises show pieces, and a holder. The show pieces bear calendar information, and when the show pieces are placed in the correct position the current day, date, month, and year will be displayed. The information size will be large enough to be seen from a distance by the user. The apparatus must be adjusted each day to show the current day, and date. At the change of the months, and year the show pieces that carry this information will require adjustment. The holder while keeping the show pieces secure, allows for adjustment and viewing.
