[First Embodiment]
[Configuration of mobile phone]
The cellular phone according to the first embodiment to which the present invention is applied includes an end portion in the short direction of a substantially rectangular upper casing, and a substantially rectangular lower casing that is substantially the same size as the upper casing. By connecting one end of the body in the short direction to each other via a hinge part, the upper case and the lower case can be folded and opened.

[Configuration of the upper casing side of the mobile phone]
FIG. 1 shows an upper casing 1 of the cellular phone according to the first embodiment, an upper casing panel 2 to be mounted on the upper casing 1, and an end 1 b (anti-hinge portion) of the upper casing 1. 2 is a perspective view of a fixing cover 3 that is attached to an upper end portion and fixes the upper casing panel 2 to the upper casing 1.

  As shown in FIG. 1, the upper casing 1 has a hinge of a surface portion 1a exposed when the mobile phone is folded (hereinafter referred to as “mounting surface portion 1a” in the meaning of a surface portion on which the casing panel is mounted). In the vicinity of the unit 4, a pair of external speaker units 5 </ b> R and 5 </ b> L for right output and left output, which are speaker units for external output, are arranged in parallel along the short direction of the upper housing 1.

  In addition, the mounting surface portion 1a of the upper housing 1 includes, for example, a liquid crystal display portion or an EL display between the external speaker portions 5R and 5L and the end portion 1b of the upper housing 1 on the side opposite to the hinge portion 4. Auxiliary display unit 6 such as a unit (EL: Electro-Luminescence) and an organic EL display unit is provided. Although this is an example, the auxiliary display unit 6 has an elliptical shape along the short direction of the upper housing 1.

  FIG. 2 shows a surface portion 1c (hereinafter referred to as a main display portion) that is exposed when the upper case 1 with the upper case case panel 2 and the fixed cover 3 attached is opened. It is referred to as a “display surface portion 1c” in the meaning of the surface portion that is present).

  As can be seen from FIG. 2, the display surface 1c, which is the surface of the upper casing 1 opposite to the mounting surface 1a, is mainly in the vicinity of the end 1b on the side opposite to the hinge 4 in the vicinity of the received voice. Is provided for receiving voice. The display surface 1 c of the upper housing 1 is provided with a main display 8 having a size that substantially occupies the area between the speaker unit 7 for received voice and the hinge 4.

As will be described later, in the case of the mobile phone of this embodiment, when the main battery 55 is removed from the lower housing 54, the power stored in the sub-battery 86 (= remaining power) is detected, and this power Information on the remaining amount is displayed on the main display unit 8.

  In addition to the above communication program, the memory 84 controls the communication circuit 72 to be in a communication stop state when the screw 66 is removed from the lower housing 54, and after the screw 66 is mounted again, A dismantling prevention program for returning the communication circuit 72 to a communicable state when a release control signal is supplied via the release control signal supply terminal 82 is stored.

  The memory 84 controls the imaging of the camera unit 78, and also has a camera control program having a viewer function for captured still images and moving images, and an email management program for controlling creation and transmission / reception of emails. A schedule book management program for managing a schedule book in which a user's schedule is registered, and a Web page published on a server device provided on a predetermined network such as a communication network or the Internet. A web browsing program for managing the phone book, a phone book management program for managing the phone book, and a music player program for playing back music content.

  The memory 84 also includes a schedule book in which a user's desired schedule is registered, user names such as user acquaintances and friends, still images (such as face photos), addresses, telephone numbers, e-mail addresses, and birth dates. , Etc., a telephone book in which music information is registered, music content that is played back based on the music player program, still image content and moving picture content that are played back based on the viewer function of the camera control program, and e-mail content that is sent and received In addition, calls and incoming / outgoing histories of telephones and e-mails are stored.

  The attachment / detachment state detection signal output unit 81 is turned off when the screw 66 is removed from the lower housing 54 as shown in FIG. 11A, and the screw 66 is attached to the lower housing as shown in FIG. 54 is a switch that is turned on when it is attached to 54. The attachment / detachment state detection signal output unit 81 is connected to the control unit 85 via the switch. The attachment / detachment state detection signal output unit 81 is supplied with a high level signal from the main battery 55 (or the sub battery 86).

  For this reason, while the screw 66 is attached to the lower housing 54, a high level signal is supplied to the control unit 85 as the wearing state detection signal via the switch that is turned on, and the screw 66 is While being detached from the housing 54, a low level signal is supplied to the control unit 85 as the detached state detection signal via the switch that is turned off.

In addition, the tip end portion 66a of the screw 66 (and the tip end portions of the screws 18a and 18b) is subjected to an insulating process by applying an insulator. The control unit 85 has a function for detecting attachment / detachment of the main battery 55 and a battery switching function. When the control unit 85 detects that the main battery 55 has been removed from the lower housing 54, the sub battery 86 is used instead of the main battery. Is controlled to supply power to the above units.

[Case disassembly prevention (suppression) operation]
Next, a housing disassembly preventing operation in the mobile phone according to the embodiment will be described. As described above, the cellular phone according to this embodiment has an upper housing case panel 2, a fixed cover 3, a lower housing operation unit housing panel 40, a lower housing, and a lower housing 54. When the rear panel 41 for housing is mounted and screwed with the screws 66, 18a, and 18b, the sub-battery 86 is charged (or charged). The main battery 55 is attached to the lower housing 54). As a result, since the screw 66 is attached, a high level signal (attached state) from the sub battery 86 (or the main battery 55) is sent to the control unit 85 via the switch of the attachment / detachment state detection signal output unit 81. Detection signal) is supplied.

  Next, after setting the wearing state detection signal to the control unit 85 as described above, the release control signal of the mobile phone is set via a signal transmission cable such as a USB cable (USB: Universal Serial Bus). The supply terminal 82 is connected to an external device such as a personal computer device. Then, a release control signal is supplied from this personal computer device. When the release control signal is supplied via the release control signal supply terminal 82, the control unit 85 controls the monitoring flag memory 83 to “1” monitoring flag for controlling the communication circuit 72 in a communicable state. Stand up.

  In the mobile phone of this embodiment, the high level signal (the wearing state detection signal) from the sub battery 86 (or the main battery 55) is thus supplied to the control unit 85, and the monitoring flag memory 83 is also supplied. Then, the factory is shipped from the factory with the monitoring flag “1” for controlling the communication circuit 72 to be communicable.

  The monitoring flag memory 83 is a non-volatile memory, and holds the stored monitoring flag even when the power supply from the sub battery 86 (or the main battery 55) is stopped.

  In this example, when the mobile phone is shipped from the factory, the sub battery 86 (or the main battery 55) is charged, and a high-level signal (detection state detection) is sent from the attachment / detachment state detection signal output unit 81 to the control unit 85. Signal) is set, and a monitoring flag “1” for controlling the communication circuit 72 to be communicable is set in the monitoring flag memory 83. A store clerk may perform such processing when selling to a user.

  Next, the control unit 85 stores the power in the memory 84 when power supply from the charged sub battery 86 (or the charged main battery 55 attached to the lower housing 54) is started and becomes operable. Based on the dismantling prevention program, the dismantling prevention operation of the casing of the mobile phone shown in the flowchart of FIG. 12 is executed.

  First, when starting the execution of the dismantling prevention program, the control unit 85 removes the screw 66 of the lower casing 54 in step S1, so that the removal state detection signal is transmitted from the attachment / detachment state detection signal output unit 81. It is determined whether or not it is supplied to 85.

  That is, in the case of the mobile phone of this embodiment, when the screw 66 of the lower housing 54 is removed as described with reference to FIGS. 11A and 11B, the attachment / detachment state detection signal output unit 81 The switch is turned off (see FIG. 11A), and the supply of a high level signal (a wearing state detection signal) from the sub battery 86 (or the main battery 55) to the control unit 85 is stopped.

  In other words, while the screw 66 is attached to the lower casing 54, a high level signal (wearing state detection signal) is supplied from the attachment / detachment state detection signal output unit 81 to the control unit 85. When the screw 66 is removed from the lower housing 54, the switch is turned off, so that a low level signal (disengagement state detection signal) is supplied from the attachment / detachment state detection signal output unit 81 to the control unit 85. become. In step S <b> 1, the control unit 85 determines whether or not the screw 66 attached to the lower housing 54 is removed by determining whether or not the detached state detection signal is supplied.

  Next, in step S <b> 2, the control unit 85 determines whether or not the main battery 55 is attached to the lower housing 54 based on the terminal voltage of the main battery 55. If the control unit 85 determines that the main battery 55 is attached to the lower housing 54, the control unit 85 proceeds to step S3, and determines that the main battery 55 is removed from the lower housing 54. If so, the process proceeds to step S10.

  When the process proceeds to step S10 on the assumption that the main battery 55 has been removed from the lower housing 54, the control unit 85 detects that the screw 66 has been removed from the lower housing 54, based on the detection of the monitoring flag memory 83. The monitoring flag standing on is lowered (= rewriting the monitoring flag “1” stored in the monitoring flag memory 83 to the monitoring flag “0”), and the process proceeds to step S11.

  As will be described later, in the case of the mobile phone of this embodiment, when the monitoring flag stored in the monitoring flag memory 55 is lowered by removing the screw 66 from the lower casing 54 (= the monitoring flag is “0”). The communication circuit 72 is forcibly controlled to be in a communication stop state. In this communication stop state, the user brings the mobile phone to a store or the like, a release control signal is supplied from a device installed on the store side, and a monitoring flag “1” is set in the monitoring flag memory 55. It will be held for a while.

  In the case of the mobile phone according to the embodiment, when the main battery 55 is mounted, the control unit 85 controls supply of power from the main battery 55 to each unit. When it is detected that the battery is detached from the body 54 (attachment / detachment detection function of the main battery 55), the battery serving as a power supply source for each part is switched from the main battery 55 to the sub battery 86 (battery switching function).

Since it is difficult to operate each part for a long time with the power stored in the sub-battery 86, the mobile phone is brought into the store while the power stored in the sub-battery 86 remains. There is a need. ,
Therefore, when the control unit 85 sets the monitoring flag to “0” and advances the process to step S11, the control unit 85 detects the remaining power of the sub battery 86 based on the voltage value of the sub battery 86, and Information on the remaining amount of power is displayed on the main display unit 8 and the process proceeds to step S5.

  Specifically, when the control unit 85 proceeds to step S11, the control unit 85 detects the remaining power level of the sub battery 86 based on the voltage value of the sub battery 86, and sets each unit based on the remaining power level. The time that can be operated is calculated. And, for example, “The remaining time for operation with the sub-battery is 5 hours. Bring the mobile phone to the store and cancel the communication stop setting.” “Please bring it in.” And the like, and display control is performed on the main display unit 8 such as a message indicating the remaining power of the sub-battery 86 and prompting the store to bring a mobile phone.

  With this message, the user can recognize the time during which the mobile phone can be operated with the sub battery 86. For this reason, the user brings the mobile phone to the store within a time when the sub battery 86 can operate.

  In this example, the message prompts the mobile phone to bring the mobile phone to the store, but this may be LED blink control (or lighting control), voice message output control, or vibration of the vibration unit 79. You may make it carry out by control etc. Further, the remaining power of the sub-battery 86 may be displayed by an indicator display on the LED or the main display unit (or the sub-display unit).

  Next, when it is determined in step S2 that the main battery 55 is attached and the process proceeds to step S3, the control unit 85 detects that the screw 66 has been removed from the lower housing 54. Thus, the monitoring flag standing in the monitoring flag memory 83 is lowered (= the monitoring flag “1” stored in the monitoring flag memory 83 is rewritten to the monitoring flag “0”).

  Next, in the case of the mobile phone according to the embodiment, as described below, when the screw 66 is removed from the lower housing 54, the monitoring flag in the monitoring flag memory 83 is rewritten to a monitoring flag of “0”. The communication circuit 72 is forcibly controlled to stop communication. For this reason, when the control unit 85 proceeds to step S4 by rewriting the monitoring flag in the monitoring flag memory 83 to “0” in step S3, for example, “bring a mobile phone to the store and set communication stop. The message for prompting the store to bring the mobile phone to the store is displayed on the main display unit 8 and the process proceeds to step S5. As a result, the user brings the mobile phone to the store according to the message.

  Next, when the process proceeds to step S5 by displaying the message in step S4 or step S11, the control unit 85 performs communication based on the monitoring flag in the monitoring flag memory 83 rewritten to "0". The circuit 72 is controlled to be in a communication stop state, and the process proceeds to step S6.

  Next, when the screw 66 once removed from the lower housing 54 is attached to the lower housing 54 again, as shown in FIG. 11B, the switch of the attachment / detachment state detection signal output unit 81 is turned on again. The ON operation is performed, and a high level signal (a wearing state detection signal) from the sub battery 86 (or the main battery 55) is supplied to the control unit 85. When the control unit 85 controls the communication circuit 72 to be in the communication stopped state, in step S6, the controller 85 monitors whether or not the wearing state detection signal is supplied, and when detecting the supply of the wearing state detection signal, the control unit 85 performs the process in step S7. Proceed to

  In step S7, a release control signal for returning the communication circuit 72 controlled by the control unit 85 to the communication stop state to a communicable state is supplied via the release control signal supply terminal 82 shown in FIG. If the release control signal is supplied, the process proceeds to step S8.

  In step S8, since the release control signal is supplied, the control unit 85 rewrites the monitoring flag in the monitoring flag memory 83 to the monitoring flag “1” again. In step S9, the controller 85 returns the communication circuit 72 to a communicable state based on the rewritten monitoring flag “1”, and returns the process to step S1. As a result, the control unit 85 starts monitoring the removal of the screw 66 again, and repeatedly executes the above steps.

  Explaining in detail each processing of step S7 to step S9 described above, when the screw 66 is removed from the lower housing 54, the communication circuit 72 is forcibly controlled to be in a communication stop state as described above. On the main display unit 8 (which may be a sub display unit), a message prompting the store to bring the mobile phone is displayed. For this reason, the user will bring the mobile phone to the store.

  On the store side, a release control signal output device such as a personal computer device 90 is installed. When a user's mobile phone is brought in, the store clerk of the store will have a release control signal supply terminal for the mobile phone brought in. 82 and the personal computer device 90 are connected by a signal transmission line such as a USB cable 91, for example. Then, a release control signal is supplied from the personal computer device 90 to the mobile phone via the USB cable 91.

  When the release control signal is supplied as shown in FIG. 13B, the control unit 85 rewrites the monitoring flag in the monitoring flag memory 83 to the monitoring flag “1”. Then, based on the rewritten “1” monitoring flag, the communication circuit 72 is returned to a communicable state.

As described above, the cellular phone according to the embodiment forms a dismantling prevention system together with the output device (in this example, the personal computer device 90) of the release control signal provided on the store side shown in FIG. ing.

[Effect of the first embodiment]
As is clear from the above description, in the case of the cellular phone according to the first embodiment, the lower casing operation unit casing panel 40 and the lower casing rear surface with respect to the lower casing 54 can be obtained by simply removing the screws 66. The panel 41 can be easily removed, and the lower casing operation unit casing panel 40 and the lower casing rear panel 41 can be easily attached to the lower casing 54 by simply attaching the screws 66. It can be carried out.

  Accordingly, the user can easily remove and attach the lower casing operation unit casing panel 40 and the lower casing rear panel 41 even if the user can freely perform it. If the user attaches a non-genuine case panel or modifies the case, a mobile phone in which the local SAR value does not satisfy the prescribed allowable value may be formed.

  However, in the case of the cellular phone according to the first embodiment, when the screw 66 is removed from the lower housing 54, the communication circuit 72 is forcibly stopped and the user places the cellular phone in the store. The communication circuit 72 remains in the communication stopped state unless it is brought in and supplied with the release control signal. For this reason, if the screw 66 is removed, a troublesome action such as bringing the mobile phone into the store is required, and therefore, the user can prevent the user from removing the screw 66. By mounting the casing panel or modifying the casing, it is possible to prevent the inconvenience of forming a mobile phone whose local SAR value does not satisfy the prescribed allowable value.

In this example, when the screw 66 is removed from the lower housing 54, the communication circuit 72 is controlled to be in a communication stop state. However, for example, an incoming call is possible and only a call cannot be made. Alternatively, the communication circuit 72 may be controlled (conversely, the communication circuit 72 may be controlled so as to be able to make a call and reject the incoming call).

[Second Embodiment]
Next, a mobile phone according to a second embodiment to which the present invention is applied will be described. In the mobile phone according to the first embodiment described above, when the screw 66 attached to the lower housing 54 is removed, the communication circuit 72 is forcibly controlled to be in a communication stopped state. The cellular phone according to the second embodiment includes a screw 66 attached to the lower casing 54, a screw 18a that screws the upper casing panel 2 and the fixing cover 3 to the upper casing 1, When any of the screws 18b is removed, the communication circuit 72 is forcibly controlled to stop communication.

The cellular phone according to the first embodiment is different from the cellular phone according to the second embodiment only in this point. For this reason, only the differences between the two will be described below, and redundant descriptions will be omitted.

[Configuration of Mobile Phone according to Second Embodiment]
In the case of the cellular phone according to the second embodiment, in addition to the attachment / detachment state detection signal output unit 81 for detecting the attachment / detachment state of the screw 66 attached to the lower housing 54 as shown in FIG. The attachment / detachment state detection signal output unit 95 that detects the attachment / detachment state of the screw 18a that fastens the housing panel 2 and the fixed cover 3 to the upper housing 1, and the upper housing case panel 2 and the fixed cover 3 are An attachment / detachment state detection signal output unit 96 for detecting the attachment / detachment state of the screw 18b screwed to the housing 1 is provided.

Each attachment / detachment state detection signal output unit 81, 95, 96 has the same configuration as described with reference to FIGS. 11A and 11B, and each screw 18a, 18b, 66 is attached. While it is being performed, a wearing state detection signal is supplied to the control unit 85, and while each screw 18a, 18b, 66 is removed, a removal state detection signal is supplied to the control unit 85. Yes.

[Operation for Preventing (Deterring) Dismantling of Case of Mobile Phone of Second Embodiment]
FIG. 15 is a flowchart showing a flow of a housing disassembly preventing (suppressing) operation in the mobile phone according to the second embodiment. In the flowchart of FIG. 15, steps that perform the same processing as the steps shown in the flowchart of FIG. Accordingly, step S21 and step S22 shown in FIG. 15 are performed to prevent the housing from being disassembled (suppressed) in the cellular phone according to the second embodiment, and the casing in the cellular phone according to the first embodiment described above. This process is different from the dismantling prevention (suppression) operation.

  In the flowchart of FIG. 15, the control unit 85 first, in step S21, the attachment / detachment state detection signal output unit 81 for detecting the attachment / detachment state of the screw 66 attached to the lower housing 54, and the housing panel for the upper housing. 2 and the attachment / detachment state detection signal output unit 95 that detects the attachment / detachment state of the screw 18a that fastens the fixing cover 3 to the upper housing 1, or the upper housing case panel 2 and the fixing cover 3 are connected to the upper housing 1 It is determined whether or not a removal state detection signal (= low level) is supplied from any of the attachment / detachment state detection signal output units among the attachment / detachment state detection signal output units 96 that detect the attachment / detachment state of the screw 18b screwed to the screw. Determine.

  Then, when the control unit 85 detects that the detached state detection signal (= low level) is supplied from any of the above-described attachment / detachment state detection signal output units 18a, 18b, 66, the process is performed after step S2. Then, the monitoring flag is rewritten to “0” as described above, and in step S5, the communication circuit 72 is forcibly controlled to stop communication, and the process proceeds to step S22.

  In step S22, it is determined whether or not the wearing state detection signals supplied by attaching the screws 18a, 18b, and 66 are supplied in a predetermined order. That is, in the case of the mobile phone according to the second embodiment, for example, the mounting order of the screws 18a, 18b, 66 is to mount the screw 18a first, then mount the screw 66, and finally mount the screw 18b. For example, the mounting order of the screws is determined in advance.

  For this reason, the control unit 85 detects the supply order of the wearing state detection signals supplied at the timing when the screws are attached, so that the screws 18a, 18b, and 66 are attached in the predetermined attachment order. It is determined whether or not. In the case of the above-described example, the control unit 85 is first supplied with the wearing state detection signal from the attachment / detachment state detection signal output unit 95 corresponding to the screw 18a, and then from the attachment / detachment state detection signal output unit 81 corresponding to the screw 66. When the wearing state detection signal is supplied, and finally the wearing state detection signal is supplied from the attachment / detachment state detection signal output unit 96 corresponding to the screw 18b, the screws 18a, 18b, 66 are arranged in the predetermined mounting order. It is determined that is attached.

  If the controller 85 determines in step S22 that the screws 18a, 18b, 66 are not attached in a predetermined attachment order, the controller 85 continues to control the communication circuit 72 to be in a communication stopped state. As a result, unless the screws 18a, 18b, and 66 are mounted in a predetermined mounting order, the communication stop state of the communication circuit 72 is maintained.

Next, when it is determined that the screws 18a, 18b, and 66 are mounted in a predetermined mounting order, the control unit 85 advances the process to step S7 to step S9. In steps S7 to S9, as described with reference to FIG. 13A, when a release control signal is supplied to the mobile phone from the personal computer device 90 installed on the store side, the control unit 85 rewrites the monitoring flag in the monitoring flag memory 83 with the monitoring flag “1”, and returns the communication circuit 72 to a communicable state based on the rewritten monitoring flag “1”.

[Effects of Second Embodiment]
As is apparent from the above description, the mobile phone according to the second embodiment has any one of the screws 18a and 18b attached to the upper housing 1 and the screws 66 attached to the lower housing 54. When the screw is removed, the control unit 85 controls the communication circuit 72 to forcibly stop communication. Each screw 18a, 18b, 66 is mounted in a predetermined mounting order, and when a release control signal is supplied from the personal computer device 90 or the like provided on the store side, the communication is stopped. The communication circuit 72 is returned to a communicable state.

As a result, the communication stop state of the communication circuit 72 is maintained unless the screws 18a, 18b, 66 are mounted in a predetermined mounting order and the release control signal is supplied, so that the return procedure is troublesome. As a result, it is possible to more strongly prevent the user from removing the screws and disassembling the casing, and obtain the same effects as those of the first embodiment described above.

[Modification]
In the description of each of the above-described embodiments, the communication circuit 72 is forcibly controlled to be in a communication stop state when the screws 18a, 18b, and 66 are removed. The attachment / detachment state detection signal output unit 81 described with reference to FIGS. 11A and 11B is provided between the housing panel 2 and the housing panel 2 for the upper housing is detached from the upper housing 1.
