And switching to the amplifying circuit 28 side for the microphone 30.

  A control circuit 36 is connected to each of the communication unit 12, the baseband unit 14, and the switching circuit 22. Switching by the switching circuit 22 described above is performed under the control of the control circuit 36. The control circuit 36 controls the audio codec 20 of the baseband unit 14, and the audio codec 20 changes the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30. The control circuit 36 is connected to the ROM 38 and controls each unit based on a system program stored in the ROM 38. The control circuit 36 is connected to a RAM 40 in which predetermined information necessary for the operation of the control circuit 36 is stored. Further, when a predetermined lock number stored in the RAM 40 is input by the numeric keypad 48, the control circuit 36 has a predetermined function (for example, a call function, an Internet connection function, a mail transmission / reception function, a camera function, a call time, (Including Internet connection time and the number of email transmissions). For example, the control circuit 36 disables the use of any of the telephone function, the Internet connection function, the mail transmission / reception function, and the camera function, or limits the call time, the Internet connection time, the number of mail transmissions, and the like. Or the usage restrictions on each of the above functions are lifted. Further, the control circuit 36 counts the number of times the number input by the numeric keypad 48 is input.

  In addition, the RAM 40 includes at least a part of predetermined functions of the cellular phone device 10 (including a call function, an Internet connection function, a mail transmission / reception function, a camera function, a call time, an Internet connection time, a mail transmission count, and the like). A plurality of lock numbers for restricting the use of or canceling the use restriction are stored. Specifically, in this embodiment, a first lock number and a second lock number which are two types of lock numbers are stored. In addition, the number of inputs counted by the control circuit 36 is sequentially stored in the RAM 40.

  A liquid crystal display 42 is connected to the control circuit 36. The display 42 displays predetermined information such as the current time, telephone number, e-mail title characters, and mail text.

It is what you have.

  Next, a function restriction release method using the mobile phone device 10 according to the present embodiment will be described based on the flowchart shown in FIG.

  The description will be made on the assumption that the first lock number is input in advance and a predetermined function is restricted by the control circuit 36.

  As shown in FIG. 2, a request for inputting the first lock number is displayed on the display 42 (S100).

  Next, the control circuit 36 determines whether or not a predetermined number has been input (S120). When the control circuit 36 determines that the predetermined number has been input, the control circuit 36 determines whether or not the number matches the first lock number stored in the RAM 40 (S140). When the control circuit 36 determines that the input number matches the first lock number, as described above, in addition to predetermined functions (call function, Internet connection function, mail transmission / reception function, camera function, call time, Internet The use restriction of the connection time and the number of times of mail transmission is also released (S160).

  On the other hand, when the control circuit 36 determines that the input number does not match the first lock number, the control circuit 36 counts the number of inputs (S180).

  Next, the control circuit 36 determines whether or not the counted number of inputs is N times (N is an integer, for example, 3 times) (S200). As a result, when it is determined that the counted number of inputs is less than N times, the state before step S100 is restored.

  On the other hand, when the control circuit 36 determines that the counted number of inputs is N or more, the control circuit 36 determines whether or not the input number matches the first lock number (S210). As a result, when the control circuit 36 determines that the input number matches the first lock number, the second lock is applied to the display 42 controlled by the control circuit 36 without releasing the use restriction of the predetermined function. A number input request is displayed (S220). If the control circuit 36 determines that the input number does not match the first lock number, the process returns to the state before S210.

  Next, the control circuit 36 determines whether or not a predetermined number has been input (S240). When the control circuit 36 determines that the predetermined number has been input, the control circuit 36 determines whether the number matches the second lock number stored in the RAM 40 (S260). When the control circuit 36 determines that the input number matches the second lock number, as described above, in addition to predetermined functions (call function, Internet connection function, mail transmission / reception function, camera function, call time, Internet Usage restrictions (including usage restrictions such as connection time, number of times of mail transmission, etc.) are released (S280). Note that after the restriction on the use of the predetermined function is released, the state before S100 is restored.

  On the other hand, if the control circuit 36 determines that the input number does not match the second lock number, the control circuit 36 counts the number of inputs (S300).

  Next, the control circuit 36 determines whether or not the counted number of inputs is N or more (S320). As a result, when the control circuit 36 determines that the counted number of inputs is less than N, the state before step S220 is restored.

  On the other hand, if the control circuit 36 determines that the counted number of inputs is N or more, the control circuit 36 determines whether the input number matches the second lock number (S330). As a result, when the control circuit 36 determines that the input number matches the second lock number, a message indicating that the input number cannot be used is displayed (S340). When the control circuit 36 determines that the input number does not match the second lock number, the state before S330 is restored.

  Note that the lock may be released when a predetermined third number is input after the display indicating that the device cannot be used. Further, if the predetermined number of inputs fails, the next number input request may be displayed.

  As described above, according to the present embodiment, since the user knows the first lock number stored in the RAM 40, naturally, the user can input the number other than the first lock number by the numeric keypad 48 a predetermined number of times or more. Since one lock number can be input immediately, the use restriction of a predetermined function can be easily released. In particular, ease of use can be improved by shortening the number of digits of the first lock number.

  Further, since a third party other than the user does not know the first lock number stored in the RAM 40, if a number is appropriately input, it is naturally input a predetermined number of times or more. If a third party accidentally inputs the first lock number stored in the RAM 40 after inputting a number different from the first lock number a predetermined number of times or more, the control circuit 36 immediately Since the use restriction of the function is not lifted and the second lock number is required to be input, security performance can be ensured.

  As a result, the mobile phone device 10 and the function restriction releasing method using the mobile phone device 10 of the present embodiment can improve both the security performance and the user's ease of use.

  In the function restriction release method using the mobile phone device 10 of the present embodiment, the configuration in which the input request is made up to the second lock number up to the second lock number is shown, but the present invention is not limited to this. The control circuit 36 determines that the number of times of input of a number other than the second lock number is N or more in response to the input request of the lock number, and even if the second lock number is accidentally input after that, the third number is further increased. A request for inputting the lock number may be displayed on the display 42. As described above, when the input of the predetermined lock number has failed N times or more, even if the lock number stored in the RAM 40 is accidentally input thereafter, the lock numbers stored in the RAM 40 are requested to be input one after another. By doing so, the security performance of the mobile phone device 10 can be remarkably improved.

  Further, in the function restriction release method using the mobile phone device 10 of the present embodiment, after the first lock number input request, the input of the first lock number fails N times or more, and then the first lock number is accidentally changed. However, the present invention is not limited to this. For example, after the input request for the first lock number, the use restriction of the predetermined function is not immediately released and the input request for the second lock number is requested. If the input of the first lock number fails N times or more and then the first lock number is accidentally input, a plurality of lock numbers (for example, the second lock number and the third lock number) stored in the RAM 40 in advance are obtained. It may be configured to request input simultaneously.
