<P>PROBLEM TO BE SOLVED: To provide a card timer device for an electric apparatus capable of generating and supplying negative ions and ozone from the electric apparatus installed in a patient bedroom and the like into the inside of the room for a healing, sterilizing, deodorizing effect based on negative ions without any great modification of the electric apparatus. <P>SOLUTION: A timer control part 5 having a magnetic/IC card reader/writer 3 and an electric apparatus control board 4 is connected to a switch control board 8 for the electric apparatus 7 via a signal cable. Alteratively, a power source socket 17 of the electric apparatus 7 is connected to the timer control part 5 via a switch relay 15. A usage frequency of the magnetic/IC card data read by the magnetic/IC card reader/writer 3 is computed by a time unit, and the data are rewritten by performing addition/subtraction. The electric apparatus 7 is operated only in the usage time by means of a microcomputer determination means, and a negative ion generator 9 and/or an ozone generator 10 interlocking with the timer control part 5 are/is arranged. <P>COPYRIGHT: (C)2004,JPO |
