<p><P>PROBLEM TO BE SOLVED: To provide a personal digital assistant which can surely detect opening of a housing with a simple configuration. <P>SOLUTION: In an assembled state in which an upper case 12 and a lower case 13 are assembled, conductive rubber 30 is inserted between both cases 12 and 13 such that the conductive rubber 30 comes into contact with both a rib 12a of the upper case 12 and a control substrate 20 fixed to the lower case 13 to be pressed. Then, a plurality of first conduction parts 24a conducting only to a first pattern part 24 and a plurality of second conduction parts 25a conducting only to a second pattern part 25 are arranged on a contact surface 22 for adding pressing to the conductive rubber 30, and the opening of the housing 11 is detected when the first pattern part 24 and the second pattern part 25 are in a non-conductive state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
