Patent ID: 7752783

Claim:
A message card, comprising: a card body having first and second leaves, said card body being foldable and unfoldable in a manner that said first leaf is movable toward and away from said second leaf between closed and opened positions; a mounting base provided on said second leaf; a supporting mechanism mounted on said mounting base and defining two opposite end openings that are aligned in a lever-moving direction and that are spaced apart from each other by a gap, said supporting mechanism having top and bottom walls and opposite first and second side walls that are opposite to each other in a transverse direction relative to the lever-driving direction and that interconnect and that cooperate with said top and bottom walls to define said end openings and said gap thereamong; a circuit unit; a switch mounted on said mounting base, coupled electrically to said circuit unit, and having an actuating member extending through said second side wall and into said gap between said end openings of said supporting mechanism; and a flexible driving lever attached to said first leaf, extending in the lever-moving direction through said end openings, and co-movable with said first leaf relative to said second leaf, said driving lever having a driving segment that is limited by said top and bottom walls so as to prevent said driving lever from being bent upwardly and downwardly and that is received in said gap to contact slidingly said actuating member so as to drive movement of said actuating member of said switch so as to enable deactivation and activation of said circuit unit when said first leaf is moved relative to said second leaf between the opened and closed positions.
