Description

  The present invention relates to an information processing apparatus, and more particularly to processing for maintaining security.

  The importance of processing for maintaining the security of information processing apparatuses is increasing. That is, the information stored in the device cannot be browsed by a person other than the user of the device, and the device cannot be operated by a person other than the user of the device. It is required to prevent the operation status of the system from being visually recognized. In particular, when a device has a communication function, it is required that the communication function cannot be used by anyone other than the user of the device. This is because the use of the communication function causes costs and may be charged to the user of the device.

  Therefore, the information processing apparatus is placed in either the security locked state or the unlocked state, and in the locked state, for example, via the user's input unit In principle, it is known not to input operation instructions. As an exception, an incoming call operation instruction and a call operation instruction to the police or fire department are input by a device having a communication function.

  The transition to the locked state is that the user's input operation is not performed for a predetermined time due to the user's predetermined input, when the apparatus is turned on, and the apparatus can be opened and closed freely. In some cases, this is done by closing the device. On the other hand, the transition to the unlocked state is performed by inputting predetermined password information, for example. The password information is input by, for example, inputting a password number that is a four-character numeric string or a password that is a character string that is not limited to numerals. Furthermore, it is performed by authentication using a user's biometric information, for example, a fingerprint.

  To use the device in the locked state, it is necessary to release the lock. This operation is troublesome when you want to use the device quickly, such as when making a call using a device with a telephone function. . Therefore, the security level is set according to the function operated by the device, the lock is released by a complicated operation to operate a high security level function, and the lock is performed by a simple operation to operate a low security level function. Is known to be released (see, for example, Patent Document 1).

  In addition, when the device is openable and closable and has an inner surface display portion that is visible when the device is in an open state and an outer surface display portion that is visible regardless of the open and closed state, the inner surface display portion is set by closing the device. The display on the display can be made invisible to a person other than the user, but the display on the outer surface display unit cannot be made invisible. Therefore, it is known that the display on the outer surface display unit is specific information that does not cause trouble due to visual recognition by a person other than the user (see, for example, Patent Document 2).

JP 2006-215730 A (2nd page, FIG. 2, FIG. 3) Japanese Unexamined Patent Publication No. 2004-40552 (page 2-3, FIG. 10, FIG. 11)

  However, the method disclosed in the above-mentioned patent document has a problem that the convenience of the user is impaired by maintaining security. That is, the method disclosed in Patent Document 1 has a problem in that it is not considered to operate a function without releasing the lock. Further, the method disclosed in Patent Document 2 has a problem that the function desired by the user cannot be operated when the apparatus is in the closed state.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a process that maintains security and does not impair user convenience.

In order to achieve the above object, an information processing apparatus of the present invention places a device in a locked state by the occurrence of a first input means, a second input means, and a lock transition event, and places the device in the locked state. When the password information inputted from the first input means is equal to the stored password information, the lock control means for releasing the locked state and the device are placed in the locked state. When there is an input from the first input means, the lock control means is operated to release the lock state, and when there is an input from the second input means, the device other than the lock control means of the device. Security control means for operating part or all of the functions.

  According to the present invention, it is possible to provide a process that maintains security and does not impair user convenience.

Furthermore, the user's first input operation and the user's second input operation are collectively referred to as the user's input operation.

  FIG. 3 is a block diagram showing a configuration of the mobile communication apparatus according to the first embodiment of the present invention. The mobile communication device includes a control unit 11 that controls the entire device, a mobile communication network communication unit 12, an antenna 12a that transmits and receives radio waves to and from a base station (not shown) of the mobile communication network, Communication network transmission / reception unit 13, call unit 14, speaker 14a used for reception, microphone 14b used for transmission, first touch panel 15a, second touch panel 15b, and first input unit 16a The second input unit 16b, the open / close detection unit 17, the telephone directory processing unit 21, the e-mail transmission / reception unit 22, the browser unit 23, the photo browsing unit 24, and the storage unit 25.

  Among these, the phone book processing unit 21, the e-mail transmission / reception unit 22, the browser unit 23, and the photo browsing unit 24 are application processing units that operate by interaction with the user. Note that the control unit 11 includes a setting function 11-1 and a security control function 11-2 as functions related to the present invention realized by executing the program. The storage unit 25 stores information by a hierarchical structure of folders and files. The storage unit 25 stores a photographic image received by the e-mail transmission / reception unit 22, received by the browser unit 23, or taken by a photographic shooting unit (not shown) as a file.

  The operation of each unit of the information processing apparatus configured as described above according to the first embodiment of the present invention will be described with reference to FIG.

  The control unit 11 is obtained by causing the open / close detection unit 17 to detect whether the upper and lower housings 1 and 2 are in an open state or a closed state at least when the apparatus is turned on and starts operating. The detected result is stored in the control unit 11. In response to an interrupt from the open / close detection unit 17, a notification that the upper and lower casings 1 and 2 are changed from the open state to the closed state and that the upper and lower cases 1 and 2 are changed from the closed state to the open state is received and received. The detected result is stored in the control unit 11.

  Through the above processing, the control unit 11 always stores whether the upper and lower casings 1 and 2 are in the open state or the closed state, and the detection result is opened depending on the stored state. Predetermined control is performed depending on the change from the state to the closed state and the change from the closed state to the open state. When one of the controls is in the open state, the control unit 11 does not display the second touch panel 15b and does not receive a notification of the user's second input operation. In the closed state, the first touch panel 15a is not displayed, and the user's first input operation notification is not received.

  The setting function 11-1 performs the security control operation when the user performs the second input operation, does not perform the security control operation, or performs the same operation as when the first input operation is performed. Based on the first input operation, the control unit 11 stores the information to be performed. The security control operation is an operation performed by the security control function 11-2 and will be described later. Here, the setting function 11-1 operates based on the user's input operation when in the unlocked state, but does not operate when the device is in the locked state.

  When a predetermined lock transition event occurs, the security control function 11-2 stores in the control unit 11 that the device is in a locked state. Here, the lock transition event is any one of that the device has transitioned to the closed state, that the device has been turned on, and that the user has performed an input operation instructing the lock transition.

  When the device is in a locked state and operates each part of the device based on the first input operation of the user, the security control function 11-2 inputs the password information by the first input operation of the user. When the personal identification number is equal to the personal identification information stored in the control unit 11, the fact that the device is in the unlocked state is stored in the control unit 11. And based on a user's 1st input operation, all the functions of the above-mentioned each part of a device are operated.

  The security control function 11-2 stores the fact that the security control operation is performed in the control unit 11 by the setting function 11-1 when operating each unit of the apparatus based on the second input operation of the user. Then, the limited functions of the above-described units of the apparatus are operated. On the other hand, if it is stored that the security control operation is not performed, all functions of the above-described units of the apparatus are operated. Note that the difference between the operation of all functions and the operation of limited functions depends on each processing unit. Some processing units do not operate at all in the limited function operation. In addition, there is a processing unit in which there is no difference between the full function operation and the limited function operation.

  If it is stored that the same operation as that performed when the first input operation is performed, the security control function 11-2 inputs the password information by the user's second input operation, and the password number is entered. Is equal to the password information stored in the control unit 11, the fact that the device is in the unlocked state is stored in the control unit 11. Then, based on the user's second input operation, all functions or limited functions of the above-described units of the apparatus are operated.

  The mobile communication network communication unit 12 transmits the high frequency signal transmitted from the base station and received by the antenna 12a to the mobile communication network transmission / reception unit 13, and the high frequency signal transmitted from the mobile communication network transmission / reception unit 13 is transmitted to the antenna 12a. To the base station.

  The mobile communication network transmission / reception unit 13 amplifies, frequency-converts and demodulates the high frequency signal from the mobile communication network communication unit 12, and transmits the digital voice signal obtained thereby to the call unit 14, the control signal to the control unit 11, and the electronic signal. A mail signal is sent to the electronic mail transmitting / receiving unit 22, and a signal related to the Web page is sent to the browser unit 23. Further, it relates to a digital voice signal transmitted from the calling unit 14, a control signal transmitted from the control unit 11, an e-mail signal transmitted from the e-mail transmitting / receiving unit 22, and a Web page transmitted from the browser unit 23. The signal is modulated, frequency converted and amplified to obtain a high frequency signal, which is sent to the mobile communication network communication unit 12.

  The calling unit 14 converts the digital audio signal transmitted from the mobile communication network transmitting / receiving unit 13 into an analog audio signal, amplifies it, and sends it to the speaker 14a. In addition, the analog audio signal transmitted from the microphone 14 b is amplified, converted into a digital audio signal, and transmitted to the mobile communication network transmitting / receiving unit 13. In the limited function operation, the call unit 14 operates all functions.

  The first touch panel 15a is used for a display for prompting the user to perform an operation, a display of contents operated by the user, a display of an operation state of the apparatus, and the like. Further, image data including icons is displayed, and the displayed data includes contact of a finger or the like to the position where the soft key is displayed on the first touch panel 15a, key operation from the first input unit 16a, Switching is performed by receiving an instruction from the control unit 11 in response to the incoming signal. The first touch panel 15a notifies the control unit 11 of information for identifying the touched position when a finger or the like is touched.

  The second touch panel 15b is used for a display for prompting the user to operate, a display of contents operated by the user, a display of an operation state of the apparatus, and the like. Further, image data including icons is displayed, and the displayed data includes contact of a finger or the like to the position where the soft key is displayed on the second touch panel 15b, key operation from the second input unit 16b, Switching is performed by receiving an instruction from the control unit 11 in response to the incoming signal. Note that when the finger or the like is touched, the second touch panel 15b notifies the control unit 11 of information for identifying the touched position.

  The first input unit 16a designates the telephone number of the communication partner and the like, and numeric keys for inputting hiragana characters, alphabetic characters and symbol characters by a toggle type input method, cursor movement, and display scrolling A plurality of function keys including an arrow key indicating an instruction, a determination key, an incoming call key, an end call key, and a power on / off key are included. When the key of the first input unit 16a is pressed, the identifier of the key is notified to the control unit 11.

  The second input unit 16b includes a plurality of function keys including a power on / off key. When the key of the second input unit 16b is pressed, the identifier of the key is notified to the control unit 11.

  The open / close detection unit 17 detects whether the upper and lower housings 1 and 2 are in an open state or a closed state depending on whether or not the magnetic field detection element 5 detects a magnetic field. And the detection request | requirement whether the upper and lower housings | casings 1 and 2 are an open state or a closed state is received, and it is notified in any state. Further, it is checked whether or not the magnetic field detection element 5 detects a magnetic field at a predetermined time interval. Due to the change in the result, the upper and lower housings 1 and 2 are changed from the open state to the closed state. When it is detected that it is in the open state, the detection result is notified to the control unit 11 via an interrupt.

  The telephone book processing unit 21 starts an operation based on a user's input operation, and newly stores, updates, searches, and searches the telephone book stored in the storage unit 25. The phone book is information in which a name, a telephone number, an e-mail address, and the like are associated. In the limited function operation, the phone book processing unit 21 performs only the phone book search operation and does not display a part of the searched information.

  The e-mail transmission / reception unit 22 transmits / receives e-mail. That is, based on a user's input operation, an e-mail consisting of an e-mail address, an e-mail subject, and an e-mail body is input. Then, the electronic mail is transmitted to a mail server device (not shown) via the mobile communication network transmission / reception unit 13. Further, the electronic mail transmitted from the mail server device is received via the mobile communication network transmitting / receiving unit 13 and stored in the storage unit 25.

  Further, based on the user's input operation, the e-mail transmission / reception unit 22 displays the list of e-mails stored in the storage unit 25 on the first touch panel 15a or the second touch panel 15b, and further, the user's input operation is performed. The e-mail selected from the list by the input operation is displayed on the first touch panel 15a or the second touch panel 15b. Further, the e-mail transmission / reception unit 22 deletes the displayed e-mail from the storage unit 25.

  In the limited function operation, the e-mail transmission / reception unit 22 performs the reception operation without performing the e-mail transmission operation. Also, some information is not displayed when displaying a list of e-mails or displaying e-mails.

  The browser unit 23 accesses the web server device (not shown) identified by the web page address designated by the user's input operation via the mobile communication network transmission / reception unit 13, and stores the Internet content stored in the device. The still image and the moving image of the signal and the characters are received via the mobile communication network transmitting / receiving unit 13 and displayed on the first touch panel 15a or the second touch panel 15b, and the sound is transmitted to the speaker 14a or the second speaker ( (Not shown). In the limited function operation, the browser unit 23 does not operate at all.

  The photo browsing unit 24 reads out the photo information stored as a file in the storage unit 25 specified by the user's input operation, and displays it on the first touch panel 15a or the second touch panel 15b. Here, at the time of reading, the hierarchy of the storage unit 25 composed of folders and files is followed according to the input operation of the user. In the limited function operation, the photo browsing unit 24 does not display some photos.

  Next, the control operation of the security control function 11-2 when each processing unit of the apparatus starts the operation by a user's input operation will be described. This control operation is performed when the user performs a second input operation, when it is stored that the security control operation is performed, or when it is not performed, or when the first input operation is performed And that the user's input operation is a first input operation or a second input operation. By this control, each of the above-described operations is performed. The operation of the processing unit changes. In addition, since the operation | movement at the time of memorize | storing that the same operation | movement as the case where 1st input operation was performed was already demonstrated, it does not repeat.

  With reference to the flowchart shown in FIG. 4, the control operation of the security control function 11-2 when it is stored that the security control operation is not performed when the user performs the second input operation will be described. . The security control function 11-2 starts its operation when the apparatus is turned on (step S101), and waits for the standby screen to be displayed by the standby screen display function (not shown) of the control unit 11 (step S102). ), The user's input operation is determined (step S103). At the start of operation, the device is in a locked state.

  When the input operation is the first input operation, the security control function 11-2 causes the first touch panel 15a to display a screen for prompting input of the password information (step S104), and the input password information is displayed on the control unit 11. It is determined whether or not it matches the password information stored in the password (step S105). If they match, the device is placed in an unlocked state (step S106), and all the functions of each part of the device are operated based on the first input operation (step S107). During this operation, the device is placed in an unlocked state. On the other hand, if they do not match, the security control function 11-2 returns to the step of prompting the input of the password information in step S104.

  If the input operation is the second input operation in step S103, the security control function 11-2 operates all the functions of each part of the apparatus based on the second input operation (step S107). During this operation, the device is placed in a locked state.

  In addition, when operating all the functions of each part of the apparatus in step S107, for example, when the upper and lower casings 1 and 2 that are in the open state are closed, the apparatus transitions to the locked state, but security control is performed. The function 11-2 operates the limited function of the processing unit that was operating when the user was in the open state based on the second input operation of the user (not shown). On the other hand, for example, when the upper and lower casings 1 and 2 that are in the closed state are opened, the apparatus performs an operation after the display operation for prompting the input of the password information in step S104 (not shown). After that, in step S107, all the functions of each part of the apparatus are operated based on the first input operation. At this time, the processing part that was operating when it was in the closed state is continuously operated. Alternatively, a new arbitrary operation may be performed.

  With reference to the flowchart shown in FIG. 5, the control operation of the security control function 11-2 when it is stored that the security control operation is performed when the user performs the second input operation will be described. This control operation is similar to the control operation when it is stored that the security control operation described with reference to the flowchart shown in FIG. 4 is not performed. Therefore, the same operation steps are denoted by the same reference numerals and description thereof is omitted.

  If the input operation is the second input operation in step S103, the security control function 11-2 operates the limiting function of each part of the device based on the second input operation (step S111). During this operation, the device is placed in a locked state.

  When the upper and lower casings 1 and 2 that are in the open state are closed during the operation of all the functions of each part of the device in step S107, the device transitions to the locked state and the security control function 11- 2 performs the operation of the limited function of the processing unit that was operating when it was in the open state based on the second input operation of the user (not shown). In other words, the process proceeds to step S111.

  On the other hand, when the upper and lower casings 1 and 2 that are in the closed state are opened while the limited functions of each part of the apparatus are performed in step S111, the apparatus displays a screen that prompts the user to input the password information in step S104. The subsequent operation is performed (not shown). After that, in step S107, all the functions of each part of the apparatus are operated based on the first input operation. At this time, the processing part that was operating when it was in the closed state is continuously operated. Alternatively, a new arbitrary operation may be performed.

  As an example of all functions and limited function operations, details of the phone book stored in the storage unit 25 will be described before describing all function operations and limited function operations of the phone book processing unit 21. FIG. 6 shows an example of the configuration of the telephone directory. This telephone book is information in which a name 25a, an alias 25b, a telephone number 25c, an electronic mail address 25d, and an address 25e are associated with each other.

  The name 25a is a character string that identifies an individual or the like. The alias 25b is an arbitrary character string assigned to an individual or the like identified by the name 25a. The telephone number 25c is a telephone number of a telephone including a mobile communication device used by an individual identified by the name 25a. The e-mail address 25d is an e-mail address used by an individual or the like identified by the name 25a. The address 25e is an address of an individual or the like identified by the name 25a. Here, the essential information is only the name 25a, and other information may not be stored.

  As described above, the difference between the all functions and the limited function operation of the phone book processing unit 21 is the phone book search operation. Therefore, the search operation will be described. FIG. 7 shows an example of display on the first touch panel 15 a by the full-function operation of the telephone directory processing unit 21. When the upper and lower casings 1 and 2 are in the open state and the full-function operation is performed, the phone book processing unit 21 first, based on the first input operation of the user, as shown in FIG. “Phonebook” is displayed in the title column 15a-1 of the first touch panel 15a, and a list of names 25a of the phonebook data is displayed in the phonebook processing section display column 15a-2. At this time, the cursor is placed on the display of one name 25a, and the name 25a on which the cursor is placed changes based on the first input operation of the user. In FIG. 7A, the fact that the cursor is placed on “Ichiro XX” is indicated by hatching.

  Next, when the first input operation of a predetermined user is performed, the phone book processing unit 21 places the cursor in the phone book processing unit display field 15a-2 as shown in FIG. 7B. The phone book data related to the name 25a is displayed. That is, in addition to the name 25a, the alias 25b, the telephone number 25c, the e-mail address 25d, and the address 25e stored in association with the name 25a are displayed.

  FIG. 8 shows a first example of display on the second touch panel 15 b by the limited function operation of the telephone directory processing unit 21. When the upper and lower casings 1 and 2 are in the closed state and the limited function operation is performed, the phone book processing unit 21 first displays the title column 15b-1 of the second touch panel 15b as shown in FIG. “Phone book” is displayed, and a list of names 25a of the phone book data is displayed in the phone book processing section display field 15b-2. The information included in this display is the same as in the case of all function operations shown in FIG.

  Next, when the second input operation of a predetermined user is performed, the phone book processing unit 21 places the cursor in the phone book processing unit display field 15b-2 as shown in FIG. 8B. The phone book data related to the name 25a is displayed. That is, the name 25a is displayed, and further, the telephone number 25c, the e-mail address 25d, and the address 25e stored in association with the name 25a are displayed with the actual data hidden and displayed in hidden characters. Here, the number of characters in the hidden character is matched with the number of characters in the actual data. Thereby, the user of the apparatus can know which one is correct when, for example, two addresses are recalled as the address 25e. However, the number of hidden characters may be determined based on a random number, and higher security can be obtained by making the number of characters in the phone book data invisible. The alias 25b is not displayed at all.

  FIG. 9 shows a second example of display on the second touch panel 15 b by the limited function operation of the telephone directory processing unit 21. When the upper and lower housings 1 and 2 are in the closed state and perform the limited function operation, the phone book processing unit 21 first displays the phone book processing unit display field of the second touch panel 15b as shown in FIG. A list of names 25a of the phone book data is displayed in 15b-2. Of the characters included in this list, approximately half of the characters selected on the basis of random numbers are turned down and displayed in turn.

  Next, when a second input operation is performed by a predetermined user, the phone book processing unit 21 places the cursor in the phone book processing unit display field 15b-2 as shown in FIG. 9B. The phone book data related to the name 25a is displayed. That is, the name 25a in which some of the characters are replaced with hidden characters is displayed, and the other displays are the same as in the first example shown in FIG.

  FIG. 10 shows a third example of display on the second touch panel 15 b by the limited function operation of the telephone directory processing unit 21. When the upper and lower housings 1 and 2 are in the closed state and perform the limited function operation, the phone book processing unit 21 first displays the phone book processing unit display field of the second touch panel 15b as shown in FIG. A list of aliases 25b of the phone book data is displayed in 15b-2. At this time, a blank line is displayed for the phone book in which the alias 25b is not stored. Further, the cursor is placed on the display of one alias 25b, and the alias 25b where the cursor is placed changes based on the second input operation of the user. In FIG. 10A, the fact that the cursor is placed on “1” is indicated by hatching.

  Next, when the second input operation of a predetermined user is performed, the phone book processing unit 21 places the cursor in the phone book processing unit display field 15b-2 as shown in FIG. 10 (b). The phone book data related to the alias 25b is displayed. That is, the alias 25b is displayed, and the name 25a, the telephone number 25c, the e-mail address 25d, and the address 25e stored in association with the alias 25b are displayed with the actual data hidden and displayed in a hidden character. Here, the number of characters in the cover character is as described above.

  In the limited function operation described with reference to FIGS. 8 to 10, the display of the phone book data shown in each figure (b) is more detailed than the list display shown in each corresponding figure (a). Information is not necessarily displayed. Therefore, the input operation for instructing the display of the phone book data may be ignored and the display shown in each figure (b) may not be performed.

  Next, the full function operation and the limited function operation of the photo browsing unit 24 will be described as another example of the full function and the limited function operation. In all functional operations, the photo browsing unit 24 causes the first and second touch panels 15a and 15b to display all of the photos stored in the storage unit 25 as files according to the folder and file hierarchy. To move up and down the folder hierarchy, a list of names of folders under a certain folder and names of folders above that folder are displayed on the first and second touch panels 15a and 15b, and one of them is used. Selection based on the user's input operation. Then, a list of names of files under a certain folder is displayed, and one of them is selected based on a user's input operation, and a photo stored as the selected file is displayed.

  In the limited function operation, the photo browsing unit 24 does not display the name of the predetermined folder on the second touch panel 15b in the folder and file hierarchy stored in the storage unit 25. Of course, the names of folders and files under the folder are not displayed, and folders and files that are not displayed cannot be selected based on the second input operation.

  As described above, the apparatus operates based on the user's first input operation, and in order to display the result of the operation on the first touch panel 15a, the apparatus is placed in an unlocked state. And all the functions of each part of the apparatus operate. This operation requires that the upper and lower casings 1 and 2 are in an open state. On the other hand, in order for the device to operate based on the user's second input operation and to display the result of the operation on the second touch panel 15b, the device may remain in the locked state. Then, all functions of each part of the apparatus or limited functions operate. In this operation, it is assumed that the upper and lower casings 1 and 2 are closed.

  When the upper and lower casings 1 and 2 are in the closed state, it takes time to input the password information by opening the upper and lower cases 1 and 2. Therefore, although it is in a closed state, even though it is a limited function, it operates without input of password information, so that it is possible to obtain an effect of maintaining security and not impairing user convenience.

  In the above description, as examples of limited functions, all functions of the call unit 14 operate, the phonebook processing unit 21 performs only a search operation, and does not display a part of the searched information. In addition, the e-mail transmission / reception unit 22 performs an e-mail receiving operation and does not display some information of the e-mail, the browser unit 23 does not operate at all, and the photo browsing unit 24 Stated that photos are not displayed. These are merely examples, and any processing unit may perform any limited operation. Further, there may be a processing unit in which all functions operate with limited function operations. These may be set by a user input operation.

  However, the control function of the control unit 11 does not operate at all as a limited function. This is because it is appropriate to operate only in a state where the lock is released after the user authentication by inputting the password information.

  In the above description, the first input operation of the user is a contact of a finger or the like to the first touch panel 15a and a key operation from the first input unit 16a, but is not limited thereto. . For example, when the first touch panel 15a does not include a touch pad and is a display, the first input operation of the user is a key operation from the first input unit 16a. Further, in the case of a device that does not include the first input unit 16a, or when the first input unit 16a includes a limited number of keys for instructing power on / off of the device, etc. The input operation is a contact of a finger or the like to the first touch panel 15a. The same applies to the second input operation of the user.

(Second Embodiment)
The mobile communication device according to the second embodiment is similar to the mobile communication device according to the first embodiment. Therefore, the same parts are denoted by the same reference numerals and description thereof is omitted. 11A and 11B show the external appearance of the foldable mobile communication device that can be freely opened and closed according to the second embodiment when the left and right casings are folded. FIG. 11A is a front view, and FIG. It is a top view.

  In this mobile communication device, the left housing 6 and the right housing 7 are connected by a hinge portion 8 so as to be rotatable about an axis BB, so that the angles of the left and right housings 6 and 7 are substantially equal. It is configured to be openable and closable between 0 degrees (closed state) and approximately 180 degrees (open state).

  A third touch panel 15c and a third input unit 16c are installed on the inner surface of the left housing 6, and a fourth touch panel 15d and a fourth input unit 16d are installed on the inner surface of the right housing 7. Is installed.

  FIG. 12 shows an appearance when the left casing 6 of this mobile communication device is rotated by the hinge portion 8 and closes to the right casing 7 to close the fold. FIG. 12 (a) is a front view, FIG. (B) is a top view. In a state in which the fold is closed, the third and fourth touch panels 15c and 15d and the third and fourth input units 16c and 16d are inside the fold. The display on the touch panels 15c and 15d cannot be visually recognized, and a finger or the like cannot be contacted. Furthermore, the keys of the third and fourth input units 16c and 16d cannot be operated.

  Although not shown, a speaker 14 a and a microphone 14 b are installed on the inner surface of the left housing 6. Further, the magnet 4 is embedded inside the left portion of the left housing 6 (a portion far from the hinge portion 8), and the magnetic field detection element 5 is inside the right portion of the right housing 7 (a portion far from the hinge portion 8). Is embedded and the left and right housings 6 and 7 are in a closed state, and the magnet 4 and the magnetic field detection element 5 are arranged so that the distance between them is short.

  FIG. 13 is a block diagram illustrating a configuration of a mobile communication device according to the second embodiment. This mobile communication device does not include the first and second touch panels 15a and 15b and the first and second input units 16a and 16b, and the third and fourth in comparison with the mobile communication device described above. Touch panels 15c and 15d and third and fourth input sections 16c and 16d are different.

  With this difference, the control unit 11 performs the following different control operations as compared to the operations in the first embodiment. First, when the left and right housings 6 and 7 are in the closed state, the third and fourth touch panels 15c and 15d are not displayed, and the third and fourth touch panels 15c and 15d and the third and fourth touch panels are not displayed. The notification of the user's input operation from the input units 16c and 16d is not received. On the other hand, when the left and right casings 6 and 7 are in the open state, display is performed on one or both of the third and fourth touch panels 15c and 15d, and notification of an input operation from one or both is received. . Furthermore, the notification of the input operation from one or both of the third and fourth input units 16c and 16d is received.

  Next, the security control function 11-2 sets the fourth touch panel 15d as the first input operation of the user by the contact of the finger or the like to the third touch panel 15c and the key operation from the third input unit 16c. The contact with the finger or the like and the key operation from the fourth input unit 16d are the second input operation of the user. Alternatively, the touch of the finger or the like to the third touch panel 15c and the key operation from the third input unit 16c are the second input operation of the user, and the touch of the finger or the like to the fourth touch panel 15d and the fourth touch are performed. The key operation from the input unit 16d is a user's first input operation.

  By controlling in this way, when the apparatus is in a locked state, the user's input operation is performed via an input device installed in the left housing 6 or an input installed in the right housing 7 Depending on whether the security control function 11-2 is performed via a device for security, the security control function 11-2 operates the entire function after shifting the device to the unlocked state through the input of the personal identification information, or is in the locked state. Control is performed as to whether to operate all functions or limited functions.

  This is because the mobile communication device according to the second embodiment is a small device suitable for carrying, and the user holds it with one hand and performs the input operation with the finger of the hand, that is, the first input operation. This is a control that takes advantage of the fact that one of the second input operations is often performed. That is, when holding with one hand and performing an input operation with a finger of that hand, the operation of the finger of that hand, even though it is a limited function, operates without the input of personal identification information, thereby ensuring security. And the user's convenience is not impaired.

(Third embodiment)
The appearance and configuration of the mobile communication device according to the third embodiment are the same as those of the mobile communication device according to the first embodiment. Therefore, description of the appearance and configuration is omitted.

  The difference between this mobile communication device and the mobile communication device according to the first embodiment is that the upper and lower housings 1 and 2 that are in the open state are mainly closed and the upper and lower housings that are in the closed state. It is in the control operation of the security control function 11-2 when the bodies 1 and 2 are opened.

  That is, since the first touch panel 15a is generally larger than the second touch panel 15b, the information that is desired to maintain security is more complicated when the upper and lower casings 1 and 2 are in the open state than when they are in the closed state. Is often displayed. Therefore, when the upper and lower casings 1 and 2 are in the open state, it is not preferable that a person other than the user visually recognizes the display on the first touch panel 15a, and the user closes the upper and lower casings 1 and 2. Can be avoided.

  Therefore, when the upper and lower casings 1 and 2 are in the closed state, if the display relating to the operation of the device is not displayed on the second touch panel 15b, the security is maintained, but the user of the device uses any device. Since it cannot be performed, there is a problem that convenience is impaired. This problem is solved by the control operation of the security control function 11-2 described below.

  Here, as for the control operation of the security control function 11-2, when the second input operation of the user is performed, the fact that the security control operation is performed is stored, the security control operation is not performed, or It does not depend on which one of the same operations as when the first input operation is performed is stored. Furthermore, it does not depend on whether or not the device is shifted to the locked state due to the occurrence of the lock transition event.

  Differences from the operations in the first embodiment will be described in the operations of the respective units in the third embodiment.

  In the third embodiment, the storage unit 25 stores a closed state display setting. FIG. 14 shows an example of the configuration of the closed state display setting. This closed state display setting is information in which the processing unit 25m and the closed state display 25n are associated with each other. The processing unit 25m is a processing unit that operates based on a user's input operation, and is one of a “phone book processing unit”, an “e-mail transmission / reception unit”, a “browser unit”, and a “photo browsing unit”. It is. Note that the unlocking operation of the setting function 11-1 and the security control function 11-2 also operates based on the user's input operation, but the control function of the control unit 11 is not stored in the processing unit 25m. This is because the display relating to the operation of these control functions should not be left to the user's intention.

  The closed state display 25n is displayed when the upper and lower casings 1 and 2 are in the closed state and the processing unit identified by the processing unit 25m is operating (in this case, the result of the operation of the processing unit is the first touch panel 15a). The display content of the second touch panel 15b when the upper and lower casings 1 and 2 are closed, and is either “same”, “select”, or “non-display” is there. In the case of “selection”, contents selected by the user, for example, “standby screen” are also stored. A plurality of closed state displays 25n associated with the “photo browsing unit” may be stored, and a folder name and / or a file name may be stored in each of them.

  The setting function 11-1 starts the operation based on the user's input operation, and displays the closed state display setting stored in the storage unit 25 on the first touch panel 15a or the second touch panel 15b. Then, one of the processing units 25m is selected based on the user's input operation. Further, any one of “same”, “selection”, and “non-display” is selected based on the user's input operation and stored in the closed state display 25n associated with the processing unit 25m. In addition, when “select” is selected, contents designated by the user, for example, “standby screen” are stored.

  Further, the setting function 11-1 depends on the input operation on the closed state display 25n associated with the processing unit 25m which is a “photo browsing unit” when a predetermined input operation is performed while the photo browsing unit 24 is operating. Then, “Same”, “Select”, and “Hide” are stored, and the folder name to which the photo information file displayed at that time belongs or the file name is stored. .

  With reference to the flowchart shown in FIG. 15, the control operation of the security control function 11-2 when the upper and lower casings 1 and 2 in the open state are closed will be described. The security control function 11-2 starts a control operation when the upper and lower casings 1 and 2 in the open state are closed (step S201), and a processing unit 25m equal to the processing unit operating at that time The associated closed state display 25n is searched from the closed state display setting (step S202). When the processing unit is the photo browsing unit 24, a plurality of values may be stored in the closed state display 25n. In this case, the folder name or file name stored together with the value, and the photo The folder name to which the file which is the photographic information displayed by the browsing unit 24 belongs or a value equal to the file name is searched.

  The security control function 11-2 determines the searched closed state display 25n (step S203), and if it is “same”, the content displayed on the first touch panel 15a is displayed on the second touch panel 15b. It is displayed (step S204). This means that the processing unit in operation continues to operate. When the display screen of the second touch panel 15b is smaller than the display screen of the first touch panel 15a, the processing unit and / or the control unit 11 reduces the display content and reduces the content displayed at the same time. Display all contents by scrolling.

  When the searched closed state display 25n is “selected”, the security control function 11-2 displays the contents stored together with “selected” on the second touch panel 15b (step S205). This means that the processing unit in operation is temporarily stopped. When the content is “standby screen”, the operation of the processing unit may be newly started based on the second input operation of the user. When this processing unit is a process that was operating when the upper and lower casings 1 and 2 are in an open state, an operation may be newly started, and the operation when the upper and lower casings 1 and 2 are closed You may be allowed to continue.

  When the searched closed state display 25n is “non-display”, the security control function 11-2 displays a menu on the second touch panel 15b (step S206). FIG. 16 shows an example of this menu screen, and the menu screen is composed of a title column 15b-1 displaying "Menu" and a menu display column 15b-3. In the menu display column 15b-3, information for identifying a part of processing of the apparatus is displayed. “Telephone call” indicates a call made by the call unit 14, and “phone book processing” indicates an operation of the phone book processing unit 21.

  The display of this menu means that the processing unit in operation is temporarily stopped. Further, the operation of the processing unit may be newly started based on the user's second input operation on the menu. When this processing unit is a process that was operating when the upper and lower casings 1 and 2 are in the open state, the security control function 11-2 may newly start the operation. The operation when 2 is closed may be continued.

  When the searched closed state display 25n is “non-display”, the security control function 11-2 is not limited to displaying the menu on the second touch panel 15b as described above, and displays nothing. The time may be displayed. In any case, the process that was operating when the upper and lower casings 1 and 2 were in the open state is not visually recognized by the display on the second touch panel 15b.

  When there is no processing unit that is operating (this is a case where the standby screen is displayed on the first touch panel 15a), the security control function 11-2 displays the standby screen as the second screen. It is displayed on the touch panel 15b (not shown). Subsequent operations are the same as those described in the operation description of step S205.

  Note that the control operation of the security control function 11-2 when the upper and lower casings 1 and 2 in the closed state are opened after the operations of steps S204, S205, and S206 is as follows (not shown). ). After the operation of step S204, and when the operation of the processing unit is not newly started by the operation of step S204 or S206 and the operation of the newly started processing unit is finished, the security control function 11-2 Continues the operation of the processing unit that was operating when in the open state, that is, immediately before step S201.

  When the operation of the processing unit is newly started by the operations of steps S204 and S206, the security control function 11-2 causes the operation of the processing unit to continue. Alternatively, the operation of the processing unit is terminated, and the operation of the processing unit that was operating immediately before step S201 is continued when the processing unit is in the open state.
