In addition, when the stop state in which the contact position is stopped after the determination unit starts to touch within the touch area corresponding to the predetermined key is determined as the contact state, the input control unit enters the stop state. The corresponding touch input is invalidated (the invention according to claim 5). In this case, the input control unit may execute the key input process in response to the pressing operation of the predetermined key in a state where the determination unit determines that the stop state is the contact state. (Invention of Claim 6).

  The input control is performed when it is determined as a contact state that a plurality of contacts have been made within a predetermined time after the determination unit starts to contact other touch areas excluding the touch area corresponding to the predetermined key. The means validates the touch input in response to the plurality of touches (the invention according to claim 7).

  Key information storage means for storing and managing key information that functions as an effective key for each screen is provided, and when any screen is displayed, the key information associated with this screen is used as an effective key for the screen. The determination means determines whether or not the touch operation is in the touch area corresponding to the valid key (the invention according to claim 8).

  Even if the key operation unit and the touch operation unit are arranged in an overlapping manner, the present invention can appropriately control the pressing operation to the key operation unit and the contact operation to the touch operation unit, and can perform a good operation. It becomes possible to maintain sex.

FIG. 3 is a diagram showing the touch operation unit 11 arranged to be superimposed on the key operation unit 10.
The touch operation unit 11 is formed of a thin film plate-like transparent member having the same shape as the upper surface of the key operation unit 10, and is stacked on the upper surface of the key operation unit 10. That is, the touch operation unit 11 is a pointing device configured by a pressure-sensitive or electrostatic transparent touch sensor, and is configured by a flexible thin transparent member, and is superimposed on the key operation unit 10. Together, they are fixed by bonding. If the corresponding part is pushed down while touching the touch operation unit 11 with a finger, a dedicated pen, etc., the key arranged immediately below is pushed down to turn on the key. The key remains off as long as it is lightly placed.

  Here, in this embodiment, two types of touch operations (touch & slide operation, double touch operation) are enabled under certain conditions, and other touch operations (one touch operation) are disabled. That is, the touch and slide operation means a contact operation in which an arbitrary position is touched with a fingertip or the like on the touch operation unit 11 and moved in an arbitrary direction, and a predetermined key (for example, up / down / left / right key 10A, determination key). 10B, numeric key 10C, etc.), even within the corresponding touch area, this touch & slide operation is valid. The double touch operation means that the touch operation is performed twice in a short time (for example, within one second) and corresponds to a predetermined key (for example, up / down / left / right key 10A, determination key 10B, number key 10C, etc.). The double touch operation in the touch area is disabled. In this embodiment, the touch and slide operation is performed when selecting a menu for selecting an arbitrary item from the menu screen, and the double touch operation is performed when a selection menu is determined.

FIG. 4 is a diagram illustrating a menu selection screen.
The menu selection screen displays a list of menu items corresponding to various functions. For example, a “photo function” that stores and manages photographs taken by the camera imaging unit 12 or the like, and is taken by the camera imaging unit 12 or the like. "Movie function" for storing and managing recorded videos, "Address book function" for storing and managing address book, "Mail function" for storing and managing sent / received mail history, "Outgoing history function" for storing and managing voice call history, Corresponding to “Received call history function”, “Calculator function”, “Clock function”, “Various setting functions” for storing and managing the history of incoming voice calls, its menu items are “Photo”, “Movie”, “Address book” , “Mail”, “Outgoing history”, “Incoming history”, “Calculator”, “Clock”, “Various settings” are listed.

  In the figure, “address book”, which is a menu item surrounded by a bold line, indicates a selection item pointed to by a virtual pointer (arrow in the figure). On this menu selection screen, guidance is displayed as an operation guide that when an arbitrary menu item is selected, it should be performed by pressing down the up / down / left / right key 10A or touch & slide operation on the touch operation unit 11. When the selection menu item is determined, a guidance display indicates that the determination key 10B should be pressed or a double touch operation on the touch operation unit 11 should be performed.

FIG. 5 shows a telephone number input screen.
The telephone number input screen is a screen for inputting the other party's telephone number at the time of voice transmission, has a telephone number input area, and sequentially displays numerical data input one by one from the key operation unit 10. The telephone number input screen also displays, as an operation guide, a guidance display indicating that the numeric key 10C should be pressed when inputting the other party's telephone number, and is determined when calling to this telephone number. A guidance display indicates that the key 10B should be pressed or a double touch operation on the touch operation unit 11 should be performed.

FIG. 6 is a diagram for explaining the operation key control information storage unit M1.
The operation key control information storage unit M1 stores and manages key information that functions as an effective key for each screen. The operation key control information storage unit M1 corresponds to the menu selection screen of FIG. 4 and the telephone number input screen of FIG. The various effective keys and their functions are stored. For example, on the menu selection screen, the up / down / left / right key 10A moves the virtual pointer, the determination key 10B determines the selection menu item, and the release key 10D is a key for canceling the menu selection screen and returning to the standby screen. Shown to work. Even if the numeric key 10C is operated on the menu selection screen, it is processed as a non-function (invalid key).

  In the telephone number input screen, the enter key 10B functions as a key for sending a call to the other party's telephone number, and the release key 10D functions as a key for canceling the menu selection screen and returning to the standby screen. 10C functions as a key for inputting a telephone number, but the up / down / left / right key 10A is a non-function key (invalid key). Based on the setting contents of the operation key control information storage unit M1, the central control unit 1 performs a virtual pointer movement process, a menu determination process, and an outgoing call as key input processes in response to a pressing operation on the key operation unit 10. Process, phone number input process, etc.

FIG. 7 is a diagram for explaining the touchpad control information storage unit M2.
The touch pad control information storage unit M2 stores and manages touch operation information valid for each screen, touch invalid area information, and contact condition information that is excluded from the application of the touch invalidation. In response to the telephone number input screen 5, functions corresponding to “touch & slide operation” and “double touch operation” in the touch operation unit 11 are stored, and central control is performed based on this setting function. The unit 1 executes a virtual pointer movement process, a menu determination process, and a transmission process, which will be described later, as the touch input process corresponding to the touch operation on the touch operation unit 11. That is, on the menu selection screen, it is shown that the touch and slide operation moves the virtual pointer, and the double touch operation functions as an operation for determining the selected menu item. On the phone number input screen, the double touch operation functions as an operation for instructing transmission to the other party's phone number, but the touch and slide operation is invalid.

  Further, the touch pad control information storage unit M2 is configured to store information indicating “valid keys” on the menu selection screen or the telephone number input screen among various keys on the key operation unit 10. In the menu selection screen, even if an area on the touch operation unit 11 corresponding to a predetermined key (for example, the up / down / left / right key 10A, the enter key 10B, the release key 10D,...) Is touched, the touch operation is basically performed. The pressing operation of the predetermined key is enabled. That is, in the menu selection screen, when the up / down / left / right key 10A is pressed, the virtual pointer can be moved. When the touch area corresponding to the up / down / left / right key 10A is touched, The touch operation is disabled, and the pressing operation at that position is enabled.

  Similarly, in order to enable menu determination even when the enter key 10B is pressed, when the touch area corresponding to the enter key 10B is touched, the touch operation in that area is invalidated, The pressing operation at the position is valid. Further, when a touch operation is performed in the touch area corresponding to the release key 10D, the touch operation in that area is invalidated, and the pressing operation at that position is valid. A touch area corresponding to these predetermined keys (valid keys) is referred to as a touch invalid area (hereinafter the same).

  Even in this telephone number input screen, even if an area on the touch operation unit 21 corresponding to a predetermined key (for example, a numeric key 10C, an enter key 10B,...) Is touched, the contact operation is basically performed. The operation of pressing the predetermined key is enabled. That is, when the numeric key 10C is pressed on the telephone number input screen, when the touch area corresponding to the numeric key 10C is touched, the telephone number can be entered. The touch operation is invalidated and the pressing operation at that position is valid. Further, in order to enable menu determination even when the enter key 10B is operated, when a touch operation is performed in the touch area corresponding to the enter key 10B, the touch operation in that area is invalidated, and at that position. The pressing operation is enabled. Further, when a touch operation is performed in the touch area corresponding to the release key 10D, the touch operation in that area is invalidated, and the pressing operation at that position is valid.

  In this way, when the inside of the touch area corresponding to the “valid key” is touched, the touch operation is basically invalidated according to the touch state, but “touch conditions that are exempt from touch invalidation” In the touch pad control information storage unit M2, “touch & slide operation” is stored corresponding to the menu selection screen of FIG. 4 and the telephone number input screen of FIG. Here, when the inside of the touch area corresponding to the “valid key” is touched, the central control unit 1 determines whether or not the touch state is a touch condition designated in advance, and this condition is met. The validity / invalidity of the contact operation is controlled according to whether or not to do so. In this case, since “touch & slide operation” is designated as “contact condition excluding application of touch invalidity”, “touch & slide operation” in the touch area corresponding to “valid key” is valid. However, other operations (double touch operation, one touch operation) are invalid. Note that the contact condition is not limited to the contact operation excluding the application of the touch invalidity, but may be a contact operation (double touch operation, one touch operation) to which the touch invalidation is applied.

  Next, the operation concept of the mobile phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

FIG. 8 is a flowchart showing an outline of the overall operation of the mobile phone device 1.
First, in response to a power-on operation (step A1), the central control unit 1 turns on the main power supply and executes various initialization processes, and then proceeds to step A2 to operate the wireless communication transmitting / receiving unit 4 Thus, standby processing for registering the current position or displaying a standby image is executed. In this standby state, when a call incoming signal from the wireless communication transmitting / receiving unit 4 is detected (YES in step A3), an incoming call notification such as generation of a melody sound is performed (step A4), and a response to establishment of a line with the other party Then, call processing is started (step A5).

  In the standby state, when an instruction operation for displaying the menu selection screen of FIG. 4 is performed (YES in step A6) or when an instruction operation for displaying the telephone number input screen of FIG. 5 is performed ( The process proceeds to an input control process corresponding to the display screen described later (step A8). If a power-off operation is performed (YES in step A9), a power-off process is executed (step A10), and this flow ends. If any other operation is performed ( As a process corresponding to this operation, for example, a mail creation process, an Internet connection process, a camera photographing process, and the like are executed (step A12).

9 to 11 are flowcharts for explaining the input control processing (step A8) corresponding to the display screen in detail.
First, the central control unit 1 displays the menu selection screen of FIG. 4 or the telephone number input screen of FIG. 5 as a screen corresponding to the display instruction operation described above (step B1 of FIG. 9), and then the touch pad. The control information storage unit M2 is accessed, and the “valid key (touch invalid area)” corresponding to the currently displayed screen is read (step B2). In this state, the presence or absence of touch on the touch operation unit 11 is checked, and a standby state is entered until the presence of a touch is detected (step B3). Now, when the presence of touch is detected at the current scan timing and the contact position is detected by the operation control unit 9 (YES in step B3), this contact position and the arrangement position of the effective key read in step B2 described above ( It is determined whether or not the touch operation is in the touch invalid area corresponding to the valid key (step B4).

  Here, when the touch operation is performed on the touch area other than the touch invalid area (NO in step B4), the process proceeds to the next step B5 to determine whether it is the detection time of the start of contact which is the start of contact. Determine. For example, when the area other than the up / down / left / right key 10A, the enter key 10B,... Is touched in the state where the menu selection screen of FIG. Determine if it is the start time. Now, if it is a contact start time, it will be investigated whether it is the second contact operation (double touch operation) within a short time with reference to the "previous touch flag" mentioned later (step B6).

  The “previous touch flag” determines whether the first contact start or the second contact start, and is turned on at the first contact start and turned off at the second contact start. Now, if the first contact is started (NO in step B6), the “previous touch flag” is turned off, so it is determined that the operation is not a double touch operation (NO in step B6), and the next step B7. Then, the central control unit 1 turns on the “previous touch flag” (step B7), and starts a time counting operation of a one-second timer (not shown) for detecting a double touch operation (step B8). In order to disregard the first contact start time, the process returns to the above-described step B3 to check for touch.

  When the “previous touch flag” is turned on, that is, when the second contact start is detected (YES in step B6), whether or not the above-mentioned 1 second timer has expired, that is, the first time It is checked whether 1 second has elapsed since the start of contact (step B9). If 1 second has elapsed, in order to invalidate the current contact operation, the “previous touch flag” is turned off (step B13), After completing the counting operation of the 1-second timer (step B14), the process returns to the above-described step B3.

  When the second contact start is detected before the 1 second timer expires (YES in step B6, NO in step B9), the second contact operation (double touch operation) within a short time (1 second) ) To be effective, the process proceeds to step B10 to check whether the currently displayed screen is the menu selection screen of FIG. 4, and if it is the menu selection screen, the menu determination process is started according to the double touch operation. Then, the processing corresponding to the selection menu is executed (step B11), but if it is the telephone number input screen of FIG. 5, the outgoing call processing is started and the call is sent to the other party's telephone number (step B12). Then, the “previous touch flag” is turned off (step B13), and the counting operation of the 1-second timer is finished (step B14). Then, the process returns to the above-described step B3 to check whether there is a touch.

  On the other hand, if it is detected in step B5 that it is not the contact start time, it is checked whether the contact position is stopped (step B15). That is, it is checked whether the contact position is stopped according to whether the contact position detected at the previous scan timing and the contact position detected at the current scan timing match. In this case, even if the positions of the two do not completely match, it is determined that the contact position is almost stopped if the movement is not a large movement as in the touch and slide operation but a slight change (shift). However, whether or not it is almost stopped is determined according to the scanning speed and the movement amount (change amount).

  Here, if it is stopped (YES in Step B15), it is checked whether the finger has been removed from the contact position, that is, whether the touch operation has been released and no touch has been detected (Step B16). Returning to the above-mentioned step B3, the presence or absence of touch is checked. If no touch is detected (YES in step B16), the above-mentioned 1-second timer has expired, that is, 1 second from the start of the first contact. It is checked whether the time has elapsed (step B17). Here, if the time is not up, the process returns to the above step B3. If the time is up, the “previous touch flag” is turned off (step B13), and the counting operation of the 1-second timer is finished ( Step B14), returning to the above-mentioned step B3.

  If the contact position is not stopped as a result of the determination in step B15 described above, it is determined that the touch and slide operation has been performed because the contact position has moved, and the process proceeds to step B18. Whether the screen being displayed is the menu selection screen of FIG. 4 is checked. If it is the menu selection screen, a process of moving the virtual pointer according to the amount of change in the contact position is executed (step B19). Then, it is checked whether the touch operation has been released and no touch has been detected (step B20). If the touch operation is in progress, the process returns to step B3 to check whether there is a touch, but when no touch is detected (step B20). YES), the “previous touch flag” is turned off (step B21), and the counting operation of the one-second timer is completed (step B22), and then the process returns to the above-described step B3.

  On the other hand, in the case of a touch operation within the touch invalid area (NO in step B4), for example, when the menu selection screen of FIG. 4 is displayed, the touch area corresponding to the up / down / left / right key 10A, the enter key 10B,. In the case of the inward contact operation, the flow proceeds to the flow of FIG. 10, and the central control unit 1 determines whether or not it is the detection time of the start of contact that is the start of contact (step B23). If there is, the process returns to step B3 in FIG. 9 to ignore the contact start time, and the presence or absence of touch is checked.

  Thereafter, when it is detected in step B23 that it is not the contact start time, it is checked whether the contact position is stopped (step B24). Even in this case, it is checked whether the contact position is stopped according to whether the contact position detected at the previous scan timing and the contact position detected at the current scan timing coincide with each other. Even if they do not coincide with each other, it is determined that the contact position is almost stopped if it is not a large movement such as a touch and slide operation but a slight change (shift). Here, if the contact position is not stopped (NO in step B24), it is determined that the touch & slide operation has been performed because the contact position has moved, and the process proceeds to step B28, where the currently displayed position is being displayed. Whether the screen is the menu selection screen of FIG. 4 is checked, and if it is the menu selection screen, a process of moving the virtual pointer according to the amount of change in the contact position is executed (step B29). And it returns to step B3 of FIG. 9, and the presence or absence of a touch is checked.

If the contact position is stopped as a result of the determination in step B24 described above, it is checked whether the key corresponding to the contact position has been pressed (step B25). Returning to step S5, the presence or absence of touch is checked. If the key is pressed (YES in step B25), the process proceeds to a key input process corresponding to the currently displayed screen (step B26).
FIG. 11 is a flowchart for explaining in detail the key input process (step B26) corresponding to the currently displayed screen.

  First, the central control unit 1 determines whether the currently displayed screen is the menu selection screen in FIG. 4 or the telephone number input screen in FIG. 5 (step C1 in FIG. 11). For example, it is checked whether the up / down / left / right key 10A, the enter key 10B, the release key 10D,... Are operated as keys effective for this screen (steps C2, C4, C6). Now, when the determination key 10B is pressed while the menu selection screen is displayed (YES in step C2), the process proceeds to execution of the menu determination process (step C3), and the up / down / left / right key 10A is pressed. If so (YES in step C4), the process moves to execution of a virtual pointer movement process (step C5). If another key such as the release key 10D is pressed (YES in step C6), the process corresponding to the valid key is executed (step C7).

  On the other hand, if the currently displayed screen is the telephone number input screen of FIG. 5 (NO in step C1), the enter key 10B, numeric key 10C, release key 10D,... It is checked whether it has been operated (steps C8, C10, C12). If the enter key 10B is pressed while the phone number input screen is displayed (YES in step C8), the process proceeds to execution of the outgoing call process (step C9), and the number key 10C is pressed. If yes (YES in step C10), the process proceeds to execution of a telephone number input process (step C11). If another key such as the release key 10D is pressed (YES in step C12), the process corresponding to the valid key is executed (step C13).

  When such a key input process (step B26) is performed, the process proceeds to step B27 in FIG. 10 to check whether the menu determination process or the outgoing call process has been performed in the key input process or whether the release key 10D has been operated. When the virtual pointer movement process or the telephone number input process is performed (NO in step B27), the process returns to step B3 in FIG. 9 to check whether there is a touch, but when the menu determination process or the outgoing call process is performed. (YES in step B27), the process returns to the standby state described above (step A2 in FIG. 8). Even when the release key 10D is operated (YES in step B27), the process returns to the standby state (step A2 in FIG. 8).

  As described above, in this embodiment, the key operation unit 10 and the touch operation unit 11 arranged at a position overlapping the key operation unit 10 are provided. The central control unit 1 includes the key operation unit 10. When a touch operation is performed on the touch operation unit 11 in a mobile phone device that executes the key input process in response to a pressing operation on the touch panel and executes the touch input process in response to a touch operation on the touch operation unit 11. It is determined whether or not the contact position is an arrangement position of a predetermined key in the key operation unit 10, the contact state is determined, and the touch input process is controlled according to the determination result, whereby the key operation unit 10 and Even if the touch operation unit 11 is arranged so as to overlap, the pressing operation on the key operation unit 10 and the touch operation on the touch operation unit 11 can be appropriately controlled, and an operation contrary to the user's intention can be performed. Limit It is possible to maintain a good operability.

  When a touch operation is performed on the touch operation unit 11, the contact position is compared with the arrangement position of a predetermined key (effective key) arranged in the key operation unit 10. The central control unit 1 determines the contact state when it is determined that the touch operation is performed within the touch area corresponding to the valid key, and, for example, the contact state is determined. If it is a touch and slide operation, that operation is validated, but if it is any other contact operation, the operation is invalidated, so that it can be distinguished from a press operation on the valid key. If there is, even if the operation is permitted, the pressing operation on the key operation unit 10 and the contact operation on the touch operation unit 11 can be appropriately controlled.

  In addition, even if a touch and slide operation is performed within the touch area corresponding to the valid key, the touch input at the start of contact when the touch area starts to be touched is invalidated to start the operation associated with the touch operation. The reaction time can be delayed, and the operation of the effective key can be prepared.

  By disabling the touch input according to the stop state in which the contact position has stopped after starting to touch the touch area corresponding to the valid key, for example, when the determination key 10B is to be pressed, Even if the touch position is slightly deviated from the key position, it is determined that the touch position is in a stopped state, and the touch input can be invalidated, and operations contrary to the user's intention can be restricted.

  When the contact position has moved within the touch area corresponding to the valid key, the touch area corresponding to the valid key is enabled by enabling touch input according to the touch movement. Touch & slide operation is possible even inside. In addition, when the touch position in the touch area corresponding to the valid key starts to be in a stopped state, the key input process is executed in response to the pressing operation at that position, thereby stopping the touch area. It is possible to execute the key input process after confirming the above, and it is possible to limit operations contrary to the user's intention.

  When multiple touches are made within a short period of time after starting to touch inside the touch area other than the touch area corresponding to the valid key, the touch input corresponding to the multiple touches is enabled. A double touch operation in the other touch area is possible.

  The operation key control information storage unit M1 stores and manages key information that functions as an effective key for each screen. When an arbitrary screen is displayed, the key information associated with this screen is stored in the operation key control information storage unit M1. As a key effective for the screen, the central control unit 1 can perform appropriate control for each screen by determining whether or not the touch operation is in the touch area corresponding to the effective key.

  In the above-described embodiment, the double touch operation in the touch area other than the touch area corresponding to the valid key is possible. However, the double touch operation in the touch area corresponding to the valid key can be performed. Also good. Even in this case, when the first contact is started, the “previous touch flag” is turned on, and the time counting operation of a 1-second timer (not shown) for detecting a double touch operation is started, and the second contact is made. If it is a start time, it is checked whether or not the above-mentioned 1 second timer has timed out. When the second contact start is detected before the time is up, it is determined that the operation is a double touch operation, and the currently displayed screen is Check if it is a menu selection screen. If it is a menu selection screen, start the menu decision process in response to a double touch operation. And the counting operation of the 1 second timer may be terminated.

  In the above-described embodiment, the touch operation unit 11 is exemplified by a case where a flexible thin transparent member is placed on the key operation unit 10. However, the touch operation unit 11 may detect the capacitance. For example, the key operation unit 10 may be embedded. Further, if the arrangement of each key constituting the key operation unit 10 is concentrated, a touch sensor having the same shape and size may be arranged on the top part of each key.

In the embodiment described above, the operation key control information storage unit M1 and the touch pad control information storage unit M2 store the valid keys for each menu selection screen and telephone number input screen. It is not limited and is arbitrary. Furthermore, the type of the effective key is not limited to the up / down / left / right key and the enter key, but is arbitrary according to the screen. .
In addition, the present invention is not limited to a mobile phone device, and can be similarly applied to a mobile terminal device such as a PDA, an electronic camera, an electronic wristwatch, and a music player, and is not limited to a mobile terminal device. 10 and an electronic device such as a stationary PC (personal computer) including the touch operation unit 11 may be used.
