[0022]
As shown in FIG. 2, the cellular phone device 1 includes a first power switch (first power switch means) 5, and a case open / close sensor that detects open / close states of the upper housing 2 and the lower housing 3. (Case open / close detection means) 8 and a second power switch connected in parallel to the first power switch 5 and turned on when the enclosure open / close sensor 8 detects that the enclosures 2 and 3 are opened. (Second power switch means) 9, power switch control section (switch control means) 10 for controlling the first power switch 5 and the second power switch 9 so as not to compete with each other, and the output of the casing open / close sensor 8 A timer (timer means) 11 for measuring time according to the signal is provided.
[0023]
Next, an operation related to the power switch of the mobile phone device configured as described above will be described. FIG. 3 is a flowchart showing an operation procedure of the mobile phone device according to the first embodiment of the present invention.
[0024]
First, in step S <b> 31, the power switch control unit 10 determines whether the mobile phone device is turned on based on the state of the first power switch 5. When the power is on (NO in step S31), the power switch control unit 10 controls the second power switch 9 not to operate (step S32). When the power is on, the operation of the second power switch 9 by the power switch control unit 10 is locked, and the power of the mobile phone device is prevented from being turned off and on by opening and closing the housing.
[0025]
On the other hand, when the first power switch 5 is in the off state (YES in step S31), the open / close state of the upper housing 2 and the lower housing 3 is detected by the housing open / close sensor 8 in step S33.
[0026]
If both housings 2 and 3 are open at this time (NO in step S33), the process returns to step S31. On the other hand, if both housings 2 and 3 are closed (YES in step S33), the process proceeds to step S34.
[0027]
Next, when the casing opening / closing sensor 8 detects that the casings 2 and 3 have shifted from the closed state to the opened state in step S34 (YES in step S34), the power switch control unit 10 The power switch 9 is turned on (step S35). Thereafter, the process returns to step S31. On the other hand, when both the casings 2 and 3 are closed (NO in step S34), the detection of the opening / closing operation is continued until the casing opening / closing sensor 8 detects that both the casings 2 and 3 are opened. .
[0028]
With such a configuration, in the present embodiment, the first power switch 5 of the mobile phone device 1 is voluntarily or in response to a request from the user, for example, at a place where the user is asked to use the mobile phone device. After turning off the power and closing both housings 2 and 3, if the upper housing 2 and the lower housing 3 are opened again for calling, starting standby, or other operations, there is no power-on operation. The mobile phone device 1 is automatically turned on.
[0029]
Therefore, according to the present embodiment, it is possible to automatically turn on the power by simply opening the closed casings 2 and 3 when the power is turned off, and the first power switch 5 is pressed. It is possible to save the trouble of performing the operation again. For this reason, operation of a mobile telephone apparatus can be started simply and rapidly, and operativity improves. In addition, it is possible to prevent a problem that a standby state is not obtained when the user forgets to perform a power-on operation with the case opened.
[0030]
FIG. 4 is a flowchart showing an operation procedure of the mobile phone device according to the second embodiment of the present invention. In the second embodiment, the operation time limit of the second power switch 9 is controlled by the timer 11 shown in FIG. In FIG. 4, the procedure to reach steps S41 to S44 is the same as steps S31 to S34 in FIG.
[0031]
That is, first, in step S41, it is determined from the state of the first power switch 5 whether or not the mobile phone device is turned on. When the power is on (NO in step S41), the power switch control unit 10 controls the second power switch 9 to be inoperable (step S42). On the other hand, if the first power switch 5 is in the off state (YES in step S41), the open / close state of the upper housing 2 and the lower housing 3 is detected by the housing open / close sensor 8 in step S43. If both housings 2 and 3 are open at this time (NO in step S43), the process returns to step S41. On the other hand, if both the casings 2 and 3 are closed (YES in step S43), the process proceeds to step S44.
[0032]
In step S44, when the casing open / close sensor 8 detects that the casings 2 and 3 have shifted from the closed state to the opened state, the timer 11 starts measuring time in step S45. On the other hand, when both the casings 2 and 3 are closed (NO in step S44), the detection of the opening / closing operation is continued until the casing opening / closing sensor 8 detects that both the casings 2 and 3 are opened. .
[0033]
Next, in step S46, it is detected by the case opening / closing sensor 8 whether both the cases 2 and 3 once opened are closed again. When it is detected that both casings 2 and 3 are closed (YES in step S46), the process returns to step S44, and detection of the opening / closing operation is detected until it is detected that both casings 2 and 3 are opened. continue.
[0034]
Subsequently, in step S47, it is detected whether or not the measurement time of the timer 11 has reached a predetermined time while both the housings 2 and 3 are open (NO in step S46). If the predetermined time has been reached, the power switch control means 10 controls the second power switch 9 in step S48 to turn on the mobile phone device 1. Thereafter, the process returns to step S41.
[0035]
On the other hand, if the time measured by the timer 11 does not reach the predetermined time in step S47, the process returns to step S46, and whether or not both cases 2 and 3 are closed again in step S46 until the elapse of the predetermined time is detected in step S47. Continue to detect opening and closing movements.
[0036]
With such a configuration, in the present embodiment, the user temporarily turns off the power and closes the housing at a place where the user is required to use the mobile phone device, and then moves in a bag or the like. Even when the casing is inadvertently opened, for example, it is possible to prevent the inconvenience that the power is turned on immediately.
[0037]
