  Further, an LED 65 is connected to the control circuit 36. The LED 65 lights up when a secondary battery (not shown) is being charged to notify that it is being charged, and blinks when an incoming call is received at the time of non-charging. To notify that the call is being received. Further, when the incoming call is not answered, the user is notified that the incoming call has been received by blinking. Also, in this embodiment, when there is an incoming call during charging and the user does not respond to the incoming call, the brightness of the LED is made lower than the brightness when the normal LED is lit (or blinking).

  The charging circuit 66 has a function of detecting whether or not a charger is connected and a function of charging a secondary battery (not shown).

  FIG. 2 is a perspective view showing a state in which the apparatus of this embodiment is charged. In FIG. 2, the mobile phone device 10 which is the device of this embodiment can be charged by connecting to an outlet 80 via an adapter 70. In addition, the mobile phone device 10 has an LED 65 that can be seen both in a closed state and an open state.

  FIG. 3 is a flowchart showing the operation of the apparatus of this embodiment. The operation of the apparatus of this embodiment will be described with reference to this flowchart.

  In step S1 in FIG. 3, when the control circuit 36 detects a signal indicating that charging has started from the charging circuit 66 (in other words, connected to the outlet 80 via the adapter 70), the process proceeds to step S2. To proceed.

  In step S2, the control circuit 36 turns on the LED 65, and proceeds to step S3. That is, by turning on the LED 65, the user is notified that the battery is currently being charged.

  In step S3, when the control circuit 36 detects a signal indicating that there is an incoming call from the baseband unit 14, the process proceeds to step S8, and if not, the process proceeds to step S4.

  In step S4, the control circuit 36 detects a signal indicating that charging has been stopped from the charging circuit 66 (in other words, the adapter 70 has been removed from the mobile phone device 10) or from the charging detection circuit 66. If a signal indicating a fully charged state is detected, the process proceeds to step S5, and if not, the process returns to step S3.

  In step S5, if the control circuit 36 determines that the current state of the device is an incoming notification state (a state in which the LED 65 notifies that there has been an incoming call but did not respond to the incoming call), an S6 step is performed. If not, the process proceeds to step S7.

  In step S6, the control circuit 36 blinks the LED 65 and returns the process to step S1.

  In step S7, the control circuit 36 turns off the LED 65 and returns the process to step S1.

  In step S8, the control circuit 36 causes the LED 65 to blink, and proceeds to step S9. Thus, by blinking the LED 65, the user is notified that there is an incoming call.

  In step S9, the control circuit 36 proceeds to step S10 in which it is determined that the cable 70 is disconnected from the mobile phone device 10 and there is an operation for responding to an incoming call from the input unit 44. Otherwise, the process proceeds to step S12. To proceed.

  In step S10, the control circuit 36 establishes a communication path with the other party by controlling the telephone communication unit 12, the baseband unit 14, the switching circuit 22 and the like, and a call is started. When this call ends, the process proceeds to step S11.

  In step S11, the control circuit 36 turns off the LED 65 and returns the process to step S1.

In step S12, the control circuit 36 turns on the LED 65 by setting the luminance of the LED 65 lower than the normal charging state (for example, the luminance at the time of LED lighting in step S2). At this time, the LED 65 is lit at a lower brightness than that in the normal charging state, so that the user can know that the charging is currently in progress and an incoming call has been received but has not been answered.
In step S13, when the control circuit 36 detects a signal indicating that there is a key operation from the input unit 44, the process proceeds to step S14, and if not, the process proceeds to step S15.

In step S14, the control circuit 36 turns off the LED 65 and then turns on the LED 65, and proceeds to step S15.
I will.

  In step S15, the control circuit 36 detects a signal indicating that charging has been stopped from the charging circuit 66 (in other words, the adapter 70 has been removed from the mobile phone device 10), or from the charging detection circuit 66. If a signal indicating a fully charged state is detected, the process proceeds to step S16, and if not, the process returns to step S3.

  In step S16, if the control circuit 36 determines that the current state of the device is an incoming notification state (a state in which the LED 65 notifies that there was an incoming call but did not respond to the incoming call), the step S17 is performed. If not, the process proceeds to step S18.

  In step S17, the control circuit 36 blinks the LED 65 and returns the process to step S1.

  In step S18, the control circuit 36 turns off the LED 65 and returns the process to step S1.

  In this way, in this embodiment device, the LED 65 is turned on during charging, and if there is an incoming call during charging and the user does not respond to the incoming call, the LED 65 lights up with a lower brightness than the normal charging state. Can know that charging is in progress and an incoming call has occurred in the past and has not been answered.

  If the secondary battery is fully charged or the adapter 70 is removed from the mobile phone device 10 while the LED 65 is lit with low brightness, the LED 65 changes from a lit state to a blinking state. For this reason, the user can know that the secondary battery is fully charged and has received a call in the past and has not responded to the call by seeing the LED 65 blinking.

  In addition, the following structure can be considered as a modification of the structure of a present Example. For example, the charging state of the secondary battery is monitored one by one, and when the LED 65 is lit at a low brightness during charging, the LED changes to blinking when it is fully charged, and the secondary battery is blinking during the LED blinking operation. When the capacity of the battery falls below a certain capacity, charging may be resumed and the blinking operation of the LED may be changed to lighting with low brightness.

  In this embodiment, the mobile phone device is used. However, it can be applied to a telephone such as a cordless phone device.

  Furthermore, in this embodiment, when there is an incoming call, the incoming call is notified by blinking the LED. However, the incoming call may be notified by changing the color of the incoming call while the LED is on. Even with such a configuration, the user can know that there is an incoming call while charging while the brightness of the LED changes after the incoming call ends.

  In the present embodiment, the mobile phone device and the cable are connected and charged. However, the present embodiment device is similarly implemented even in a structure in which the mobile phone device is charged by being placed on a charger. Is possible.

It is a block diagram of a present Example apparatus. It is a perspective view of a present Example apparatus. It is a flowchart which shows operation | movement of a present Example apparatus.
