<p>PROBLEM TO BE SOLVED: To issue various kinds of warnings and bring out breaking means, by providing an isolation layer in the inside face of a metallic case and forming a metallic layer thereon and using the case itself as a switch or a relay. SOLUTION: A conductive cable 4 coming into contact with an iron plate is put in the inside face of an iron case 1 and an aluminum foil sheet 3 is stuck on a both-face adhesive tape and a conductive cable 5 coming contact with this foil as well is stuck and fixed thereto. Then, conductive cables 4, 5 are connected to switch terminals of a flush circuit of a disposable camera. Then, the flush circuit is removed and connected from the terminals to the voltage supply circuit of an electronic circuit and the earth line. Then, the case is cut by a disk grinder. In this way, the iron plate as a switch of the flush circuit and the conductive cables 4, 5 of the aluminum foil 3 are closed and high tension voltage is supplied to the electronic parts in the case 1 and the parts are broken. Accordingly, it is made possible to issue warnings or break recorded contents or elements in case of ROM or the like.</p> |
