  The control unit 7 is an example of a control unit.

  The control unit 7 controls the operation of the mobile terminal 100.

  For example, the control unit 7 controls the lock by the security lock function in each function of the mobile terminal 100 and the release of the lock.

  For example, the control unit 7 matches the selection order of the point “6”, the point “10”, and the point “3” that are sequentially selected at the position of the touch that changes in the transition state with the selection order expressed in the release condition. When the touch operation is detected by the touch panel unit 6, the lock by the security lock function is released.

  The key operation unit 8 is a so-called hard key and accepts various inputs.

  Next, the operation will be described.

  First, the operation for setting the release condition will be described.

  When the touch panel unit 6 or the key operation unit 8 receives a setting instruction for setting the release condition, the control unit 7 displays a setting screen for setting the release condition on the LCD display unit 3.

  FIG. 5 is a diagram illustrating an example of the setting screen 32.

  The user of the mobile terminal 100 touches and selects an arbitrary plurality of points to be set as a plurality of operation targets from the points “1” to “16” in the setting screen 32 in order.

  Hereinafter, it is assumed that point “6”, point “10”, and point “3” are touched in the order of point “6”, point “10”, and point “3”, and are selected as a plurality of operation targets.

  When the point “6”, the point “10”, and the point “3” are selected by touching the point “6”, the point “10”, and the point “3” in this order, the touch panel unit 6 displays the point “6”. Point “10” and point “3” are detected in the order of point “6”, point “10”, and point “3”.

  The touch panel unit 6 outputs points sequentially detected from the setting screen 32 to the control unit 7.

  When the control unit 7 receives the point detection result from the touch panel unit 6 in a state where the setting screen 32 is displayed, the control unit 7 sets a cancellation condition indicating the detection result.

  For example, when the touch panel unit 6 detects the point “6”, the point “10”, and the point “3” in the order of the point “6”, the point “10”, and the point “3”, the control unit 7 A release condition indicating that “6” is selected first (first), point “10” is selected next (second), and point “3” is selected last (third) is set ( (See FIG. 4).

  The control unit 7 stores the release condition in the memory unit 5.

  Next, an icon display example when the security lock function is locked and an icon display example when the security lock function is unlocked will be described.

  FIG. 6 is a diagram illustrating a display example of icons when transitioning to each screen.

  The touch panel unit 6 or the key operation unit 8 accepts a lock instruction to lock by the security lock function in a state where the standby screen 33 when the lock is not performed by the security lock function is displayed on the LCD display unit 3. And the control part 7 performs the lock by a security lock function about the function (a mail function, a telephone directory function, and a telephone function) set with the security lock function by the setting information in the memory part 5.

  When the lock by the security lock function is executed, the display screen of the LCD display unit 3 is switched to the screen 34 after the security lock is set.

  When the lock by the security lock function is executed, the mail, phonebook, and telephone functions cannot be executed. Therefore, “x” is added to the icons corresponding to the mail, phonebook, and telephone functions on the screen 34. ing.

  Thereafter, when an operation for releasing the lock by the security lock function is performed, the control unit 7 releases the lock by the security lock function.

  When the lock by the security lock function is released, the display screen of the LCD display unit 3 is switched to the screen 35 after the security lock is released. The screen 35 shows the same contents as the standby screen 33.

  When the lock by the security lock function is released, the mail, phonebook, and telephone functions can be executed. In the screen 35, the icons corresponding to the mail, phonebook, and telephone functions have been added. “X” disappears.

  Next, an operation example for releasing the lock by the security lock function will be described.

  FIG. 7 is a diagram for explaining an operation example for releasing the lock by the security lock function.

  In the memory unit 5, the point “6” is selected first (first), the point “10” is selected next (second), and the point “3” is selected last (third). It is assumed that a release condition (see FIG. 4) indicating that is held.

  When the user of the mobile terminal 100 tries to execute a function locked by the security lock function and touches an icon to which an “x” display is added on the screen 34, the control unit 7 displays a grid pattern on the LCD display unit 3. A screen is displayed, and the input of a release pattern corresponding to a password for releasing the lock by the security lock function is awaited.

  The release pattern is a transition situation in which the touch position transitions on the grid screen while touching the grid screen continues, and all the points that are sequentially selected at the transition touch position are in the selection order. In addition, the selected point includes a plurality of points indicated in the release condition, and the order of selection among the points in the selected point is indicated in the release condition. It satisfies the selection order.

  The user of the portable terminal 100 first touches the point “6”, which is the first point of the release condition for releasing the lock by the security lock function, with a finger (see FIG. 7). When the touch panel unit 6 detects a touch on the point “6”, the touch panel unit 6 outputs the detection result to the control unit 7.

  Thereafter, the user of the portable terminal 100 moves the finger downward in FIG. 7 to the position of the point “10” that is the second point while continuing to touch the touch panel 6 with the finger. When the touch panel unit 6 detects a touch on the point “10” in the transition state, the touch panel unit 6 outputs the detection result to the control unit 7.

  When the finger touches the point “6” and then moves from the point “6” to the point “10” without passing through another point while the finger touches the touch panel unit 6, the control unit 7 causes the touch panel unit 6 to move. Based on the detection result, an arrow 36 from the point “6” to the point “10” is displayed on the grid-like screen.

  Note that the arrow 36 indicates that the finger has passed the point “6” as the first point and the point “10” as the second point in the transition state.

  Thereafter, the user of the mobile terminal 100 moves the finger in the right direction in FIG. 7 to the position of the point “11” while continuing to touch the touch panel unit 6 with the finger. When the touch panel unit 6 detects a touch on the point “11” in the transition state, the touch panel unit 6 outputs the detection result to the control unit 7.

  The control unit 7 displays an arrow 37 from the point “10” to the point “11” on the grid-like screen based on the detection result of the touch panel unit 6 representing the touch to the point “11” in the transition state. .

  Thereafter, the user of the mobile terminal 100 moves the finger upward in FIG. 7 to the position of the point “7” while continuing to touch the touch panel unit 6 with the finger. When the touch panel unit 6 detects a touch on the point “7” in the transition state, the touch panel unit 6 outputs the detection result to the control unit 7.

  Based on the detection result of the touch panel unit 6 representing the touch to the point “7” in the transition state, the control unit 7 displays the arrow 38 from the point “11” to the point “7” on the grid-like screen. .

  Thereafter, the user of the portable terminal 100 moves the finger upward in FIG. 7 to the position of the point “3”, which is the third point, while continuing to touch the touch panel unit 6 with the finger. When the touch panel unit 6 detects a touch on the point “3” in the transition state, the touch panel unit 6 outputs the detection result to the control unit 7.

  The control unit 7 displays an arrow 39 from the point “7” to the point “3” on the grid-like screen based on the detection result of the touch panel unit 6 representing the touch to the point “3” in the transition state. .

  The arrow 39 indicates that the finger has passed the point “3” that is the third point in the transition state.

  In the example illustrated in FIG. 7, the order in which the touch panel unit 6 detects the point “6”, the point “10”, and the point “3” matches the order represented by the release condition in the memory unit 5.

  For this reason, when the user of the mobile terminal 100 releases the touch by releasing the finger from the touch panel unit 6 after the operation up to the point “3”, the control unit 7 releases the lock by the security lock function, and the LCD display unit 3 The screen 35 (see FIG. 6) after the security lock is released is displayed.

  In order to release the lock by the security lock function, the order in which the point “6”, the point “10”, and the point “3” are selected should match the order indicated in the release condition in the memory unit 5. The path between the point “6” and the point “10” and the path between the point “10” and the point “3” are arbitrary.

  For this reason, there are a plurality of release patterns that satisfy one release condition in the memory unit 5.

  Therefore, when there is a possibility that the input of the release pattern is seen by others, the user of the mobile terminal 100 uses a complicated release pattern among a plurality of release patterns, so that the other person can set the release pattern. It becomes possible to make it difficult to recognize.

  FIG. 8 is a flowchart for explaining the operation for releasing the lock by the security lock function.

  The control unit 7 determines whether the touch panel unit 6 has been touched based on the output of the touch panel unit 6 (step 101).

  When the touch panel unit 6 is touched, the control unit 7 initializes an instruction unit (for example, a pointer) indicating a read position in the release condition, and sets the read position of the release condition indicated by the instruction unit to the first position of the release condition. The position of the point is set (step 102). The instruction unit is built in the control unit 7.

  Next, the control unit 7 refers to the output of the touch panel unit 6 to determine whether or not a point has been detected (step 103).

  If a point has been detected, the control unit 7 reads the point to be operated from the read position of the release condition indicated by the instruction unit (step 104). The first point is point “6”.

  The control unit 7 determines whether the point detected by the touch panel unit 6 matches the point read from the release condition (step 105), and if not, returns to step 103.

  When the point detected by the touch panel unit 6 coincides with the point read from the release condition, the control unit 7 determines that the point read from the release condition is the last point indicated in the release condition. It is determined whether or not it is a point (step 106).

  If the point read from the release condition is not the last point indicated in the release condition, the control unit 7 updates the read position of the release condition indicated by the instruction unit to the position of the next point. (Step 107), the process returns to Step 103.

  If the release position read position indicated by the instruction unit is the position of the first point, the position of the next point is the position of the second point (point “10”).

  Further, when the reading position of the release condition indicated by the instruction unit is the position of the second point, the position of the next point is the position of the third point (point “3”).

  When the point read from the release condition in step 106 is the last point (point “3”) indicated in the release condition, the control unit 7 refers to the output of the touch panel unit 6 and touches it. Is released (step 108). If the touch is released, the lock by the security lock function is released, and the screen 35 (see FIG. 6) after the security lock is released is displayed on the LCD display unit 3. (Step 109).

  If the touch is not released, the control unit 7 loops step 108.

  If the display screen of the LCD display unit 3 has transitioned to the screen after the security lock is released, if another function set to have the security lock function is to be executed next, it can be executed as it is.

  When returning to the screen locked by the security lock function, that is, when executing the lock by the security lock function, for example, a soft key for executing the lock by the security lock function is provided on the LCD display unit 3. When the soft key is displayed and the soft key is operated, the control unit 7 may execute the lock by the security lock function, or perform control when there is no operation for a certain period after the lock by the security lock function is released. The unit 7 may automatically return to the state where the lock by the security lock function is made.

  Next, the effect of this embodiment will be described.

  According to the present embodiment, the LCD display unit 3 displays a screen (see FIG. 7) representing a plurality of operation objects (for example, point “6”, point “10”, and point “3”).

  The memory unit 5 stores a release condition indicating the selection order of a plurality of operation objects as a condition for releasing the lock by the security lock function (see FIG. 4).

  The touch panel unit 6 detects a touch operation on the screen of the LCD display unit 3.

  When the touch panel unit 6 detects a touch operation in which the selection order of a plurality of operation targets that are sequentially selected at the position of the touch that changes in the transition state matches the selection order indicated in the release condition, Unlock the security lock function.

  For this reason, in order to release the lock by the security lock function, the order in which the plurality of operation targets are selected only needs to match the order indicated in the release condition in the memory unit 5, and each operation target in the transition state The path between them is optional.

  For this reason, a plurality of release patterns satisfying one release condition in the memory unit 5 exist by changing the path between the operation targets in the transition state.

  Therefore, when there is a possibility that the input of the release pattern is seen by others, the user of the mobile terminal 100 uses a complicated release pattern among a plurality of release patterns, so that the other person can set the release pattern. It becomes possible to make it difficult to recognize.

  Note that the above-described effect is also achieved by an electronic device including the LCD display unit 3, the memory unit 5, the touch panel unit 6, and the control unit 7.

  FIG. 9 is a diagram illustrating an electronic device including the LCD display unit 3, the memory unit 5, the touch panel unit 6, and the control unit 7.

  In the present embodiment, the LCD display unit 3 displays a grid-like screen in which each of the plurality of operation objects is assigned to any grid point.

  For this reason, the user of the mobile terminal 100 can easily input various release patterns by using the lattice.

  Note that the present embodiment may be modified as follows.

  In the control unit 7, the selection order of the plurality of operation objects that are sequentially selected at the position of the touch that changes in the transition state matches the selection order indicated in the release condition, and the same operation object is selected in the transition state When the touch panel unit 6 detects an untouched touch operation, the lock by the security lock function is released.

  For example, in the situation where the memory unit 5 stores the release condition shown in FIG. 4 as the release condition, the touch panel unit 6 is in the transition state, the point “6”, the point “10”, the point “6”, the point When “10” and point “3” are detected in this order, the control unit 7A does not release the lock by the security lock function.

  According to this modification, when the same operation target is selected, unlocking by the security lock function can be prohibited.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  FIG. 10 is a block diagram showing a mobile terminal 100A which is an example of an electronic apparatus according to the second embodiment of the present invention.

  In FIG. 10, the same components as those shown in FIG. Hereinafter, the portable terminal 100A illustrated in FIG. 10 will be described focusing on differences from the portable terminal 100 illustrated in FIG.

  In the mobile terminal 100 </ b> A illustrated in FIG. 10, the memory unit 5 </ b> A is used instead of the memory unit 5 illustrated in FIG. 1, and the control unit 7 </ b> A is used instead of the control unit 7.

  The memory unit 5A is an example of a storage unit. The memory unit 5A stores the total number of transition points in addition to the information stored in the memory unit 5. The total number of transition points is an example of a predetermined number. Needless to say, the total number of transition points may be any number.

  The control unit 7A is an example of a control unit.

  In the control unit 7A, the touch panel unit 6 detects a touch operation in which the selection order of a plurality of operation objects sequentially selected at the position of the touch that changes in the transition state matches the selection order indicated in the release condition, and When the number of points detected by the touch panel unit 6 matches the total number of transition points, the lock by the security lock function is released.

  FIG. 11 is a diagram illustrating an example of the release condition and the total number of transition points.

  In FIG. 11, the release condition is the same as that shown in the first embodiment, and points “6”, “10”, and “3” are represented as a plurality of operation targets, and the selection order is also the same as in the first embodiment. Same as shown. The total number of transition points represents “8”.

  In this embodiment, in the touch operation for releasing the lock by the security lock function, the path between the operation targets is arbitrary, but the release pattern must be such that the total number of transitioned points is “8”. .

  The total number of transition points is set by inputting a numerical value after setting the cancellation condition, and is stored in the memory unit 5A.

  In the operation example for releasing the lock by the security lock function shown in FIG. 7, the finger passes through the points “6”, “10”, and “3” that are release conditions in this order, and the release conditions are satisfied. Yes. However, the number of transition points is point “6”, point “10”, point “11”, point “7”, and point “3”, and the total number of transition points is “5”. Unlike “8”, since the condition for the total number of transition points is not satisfied, the lock is not released by the security lock function.

  FIG. 12 is a diagram for explaining an operation example for releasing the lock by the security lock function in the second embodiment.

  It is assumed that the control unit 7A displays a grid-like screen on the LCD display unit 3 and waits for an input of a release pattern corresponding to a password for releasing the lock by the security lock function.

  In this situation, the user of the portable terminal 100A first touches the point “6”, which is the first point of the release condition, with the finger, and continues to touch the finger to the position of the point “9”. 12A, the control unit 7A displays an arrow 121 from the point “6” to the point “9” on the grid-like screen.

  After that, when the user of the portable terminal 100A moves the finger to the position of the point “10” in the right direction in FIG. 12 while continuing the touch with the finger on the touch panel unit 6, the control unit 7A displays the grid-like screen. In addition, an arrow 122 from point “9” to point “10” is displayed.

  At this time, the points “6” and “10” indicated as the first and second locations of the release condition are selected.

  Thereafter, when the user of the mobile terminal 100A moves the finger in the right direction in FIG. 12 to the position of the point “11” while continuing the touch with the finger on the touch panel unit 6, the control unit 7A displays the grid-like screen. The arrow 123 from the point “10” to the point “11” is displayed.

  Thereafter, when the user of the mobile terminal 100A continues to touch the touch panel unit 6 with the finger and moves the finger upward to the position of the point “7” in FIG. 12, the control unit 7A displays a grid-like screen. The arrow 124 from the point “11” to the point “7” is displayed.

  Thereafter, when the user of the mobile terminal 100A continues to touch the touch panel unit 6 with the finger and moves the finger to the position of the point “8” in the right direction in FIG. 12, the control unit 7A displays the lattice-shaped screen. In addition, an arrow 125 from point “7” to point “8” is displayed.

  Thereafter, when the user of the mobile terminal 100A continues to touch the touch panel unit 6 with the finger and moves the finger upward to the position of the point “4” in FIG. 12, the control unit 7A displays the grid-like screen. In addition, an arrow 126 from point “8” to point “4” is displayed.

  Thereafter, when the user of the mobile terminal 100A continues to touch the touch panel unit 6 with the finger and moves the finger to the position of the point “3” in the left direction in FIG. 12, the control unit 7A displays the lattice-shaped screen. In addition, an arrow 127 from the point “4” to the point “3” is displayed.

  At this point, the point “3” indicated as the third location of the release condition is selected.

  In this touch operation, the finger passes through the points “6”, “10”, and “3”, which are a plurality of operation targets, in the order indicated by the release condition, and thus the release condition is satisfied. In addition, the points transitioned during the touch operation are point “6”, point “9”, point “10”, point “11”, point “7”, point “8”, point “4”, point “3”. Since the total number of transitioned points is “8”, it matches the total number of transition points “8” in the memory unit 5A and satisfies the condition for the total number of transition points. For this reason, the display screen of the LCD display unit 3 is changed to a screen after the security lock is released.

  FIG. 13 is a flowchart for explaining the operation for releasing the lock by the security lock function in the present embodiment.

  The control unit 7A determines whether the touch panel unit 6 has been touched based on the output of the touch panel unit 6 (step 201).

  When the touch panel unit 6 is touched, the control unit 7A initializes an instruction unit (for example, a pointer) indicating a reading position in the release condition and a count value of the total number of touched points, and the instruction unit indicates The read position of the release condition is set to the position of the first point of the release condition, and the count value is set to 0 (step 202). The count value is held by the control unit 7A.

  Next, the control unit 7A refers to the output of the touch panel unit 6 to determine whether or not a point has been detected (step 203).

  If a point has been detected, the control unit 7A reads the point to be operated from the read position of the release condition indicated by the instruction unit (step 204). The first point is point “6”.

  Subsequently, the control unit 7A adds 1 to the count value in the control unit 7A (step 205).

  Subsequently, the control unit 7A determines whether or not the point detected by the touch panel unit 6 matches the point read from the release condition (step 206), and if not, returns to step 203.

  If the point detected by the touch panel unit 6 matches the point read from the release condition, the control unit 7A determines that the point read from the release condition is the last point indicated in the release condition. It is determined whether or not it is a point (step 207).

  If the point read from the cancellation condition is not the last point indicated in the cancellation condition, the control unit 7A updates the readout position of the cancellation condition indicated by the instruction unit to the position of the next point. (Step 208), the process returns to Step 203.

  If the release position read position indicated by the instruction unit is the position of the first point, the position of the next point is the position of the second point (point “10”).

  Further, when the reading position of the release condition indicated by the instruction unit is the position of the second point, the position of the next point is the position of the third point (point “3”).

  In step 207, if the point read from the release condition is the last point indicated in the release condition, the control unit 7A refers to the output of the touch panel unit 6 to determine whether or not the touch is released. (Step 209).

  If the touch is not released, the control unit 7A loops Step 209.

  If the touch is released, the control unit 7A reads the total number of transition points from the memory unit 5A (step 210). Here, it is assumed that the total number of transition points is set to “8”.

  Subsequently, the control unit 7A determines whether or not the count value in the control unit 7A matches the total number of transition points (step 211). If they do not match, the control unit 7A determines that the release pattern input has failed, and the first step Return to 201.

  If the count value in the control unit 7A matches the total number of transition points, the control unit 7A releases the lock by the security lock function and displays the screen 35 after the security lock is released on the LCD display unit 3 (see FIG. 6). Is displayed (step 212).

  According to the present embodiment, the control unit 7A performs a touch operation in which a selection order of a plurality of operation targets sequentially selected at a touch position that changes in a transition state matches a selection order indicated in the release condition. When the number of points detected by the unit 6 and detected by the touch panel unit 6 matches the total number of transition points, the lock by the security lock function is released.

  For this reason, it becomes possible to complicate the touch operation required for releasing the lock by the security lock function.

(Third embodiment)
Next, a third embodiment of the present invention will be described.

  FIG. 14 is a block diagram showing a mobile terminal 100B which is an example of an electronic apparatus according to the third embodiment of the present invention.

  In FIG. 14, the same components as those shown in FIG. Hereinafter, the portable terminal 100B illustrated in FIG. 14 will be described focusing on differences from the portable terminal 100 illustrated in FIG.

  In the mobile terminal 100 </ b> B illustrated in FIG. 14, the memory unit 5 </ b> B is used instead of the memory unit 5 illustrated in FIG. 1, and the control unit 7 </ b> B is used instead of the control unit 7.

  The control unit 7B is an example of a control unit.

  The control unit 7B generates input information in which identification information (numbers) assigned to the points sequentially selected at the position of the touch that changes in the transition state is arranged in the selection order.

  The memory unit 5B is an example of a storage unit.

  In addition to the information stored in the memory unit 5, the memory unit 5 </ b> B stores input information generated in a transition state in which a touch operation used for unlocking in the past has been performed.

  In the control unit 7B, the touch panel unit 6 detects a touch operation in which the selection order of a plurality of operation objects sequentially selected at the position of the touch that changes in the current transition state matches the selection order represented in the release condition. And when the input information produced | generated this time differs from the input information in the memory part 5B, the lock | rock by a security lock function is cancelled | released.

  FIG. 15 is a flowchart for explaining the operation for releasing the lock by the security lock function in the present embodiment.

  15, steps 301 to 307 are the same as steps 101 to 107 shown in FIG. 8, and steps 312 to 313 are the same as steps 108 to 109 shown in FIG. 8. It is processing. For this reason, the description about steps 301-307 and steps 312-313 is abbreviate | omitted.

  If the point read from the release condition in step 306 is the last point indicated in the release condition, the control unit 7B generates a detection history of the points detected in the current transition state (step 306). 308). It is assumed that the current point detection history is “point“ 6 ”, point“ 10 ”, point“ 11 ”, point“ 7 ”, and point“ 3 ”.

  The point detection history detected in the transition state is an example of input information in which numbers assigned to the points sequentially selected at the position of the touch that transitions in the transition state are arranged in the selection order.

  Subsequently, the control unit 7B reads the previous point detection history from the memory unit 5B (step 309).

  Subsequently, the control unit 7B determines whether or not the current point detection history matches the previous point detection history (step 310). If they match, the control function 7B does not release the lock by the security function and proceeds to step 301. Return.

  If the current point detection history does not match the previous point detection history, the control unit 7B stores the current point detection history in the memory unit 5B (step 311), and then executes the processing from step 312 onward. .

  According to the present embodiment, if the current point detection history matches the previous point detection history, the lock by the security function is not released.

  For this reason, even if a third party steals a touch operation for unlocking the lock by the security function by the user of the mobile terminal 100B and reproduces the touch operation that has been seen, the lock by the security function is not released. Therefore, it is possible to increase the security level of the mobile terminal 100B.

  Note that the functions added in the second embodiment (the memory unit stores the total number of transition points, and the control unit detects the points detected by the touch panel unit 6 as one of the conditions for releasing the lock by the security lock function. The function using the condition that the number matches the total number of transition points) may be added to the third embodiment.

  In this case, the memory unit 5B stores the total number of transition points. In the control unit 7B, the touch panel unit 6 detects a touch operation in which the selection order of a plurality of operation objects sequentially selected at the position of the touch that changes in the current transition state matches the selection order represented in the release condition, In addition, when the number of points detected this time on the touch panel unit 6 matches the total number of transition points in the memory unit 5B, and the input information generated this time is different from the input information in the memory unit 5B, security is performed. Release the lock by the function.

  In each of the above embodiments, the mobile terminal may be realized by a computer. In this case, the computer reads and executes a program recorded on a computer-readable recording medium, and executes the functions of the portable terminal 100, 100A, or 100B.
