<p><P>PROBLEM TO BE SOLVED: To dissolve a freeze state of an electronic device including a software processing execution means using only operation keys essential for general use. <P>SOLUTION: When continuous press-down time of a power source key 17, which is measured by a clock unit 33, is not more than a first predetermined time, a first control unit 28 takes a suspend state. When the continuous press-down time of the key 17 exceeds a second predetermined time longer than the first predetermined time but is not more than a third predetermined time, the first control unit 28 controls to interrupt the power supply of a portable communication terminal 1. A second control unit 32 is connected to the clock unit 33 and an input end of reset signal of the first control unit 28. The second control unit 32 includes only hardware. When the first control unit 28 gets into the freeze state, the second control unit 32 transmits reset signal to the first control unit 28 when it is determined that the continuous press-down time of the key 17 measured by the clock unit 33 exceeds the third predetermined time longer than the second predetemrined time. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
