  The main body side housing 2 and the display side housing 3 are connected by a pair of left and right connecting portions 8a and 8b at respective end portions. The connecting portions 8a and 8b are hinges, and support the main body side housing 2 and the display side housing 3 so as to be freely opened and closed.

  The notebook PC 1 includes a storage unit 9 that stores the touch pen 10 on one side surface of the main body side housing 2. The touch pen 10 is taken out from the storage unit 9 when used, and stored in the storage unit 9 when not used.

  The touch pen 10 is an indicator that can be carried by the user and is held by the user and used as an input device of the notebook PC 1. In addition, the kind of touch pen 10 is not specifically limited, A passive type, an active type, or another kind may be sufficient.

  FIG. 2 is an enlarged schematic view of the storage unit 9.

  The storage unit 9 is provided with a storage detection switch 11. The storage detection switch 11 detects whether or not the touch pen 10 is stored in the storage unit 9. More specifically, when the touch pen 10 is stored in the storage unit 9, the storage detection switch 11 is pushed down in the internal direction of the main body side housing 2 (A direction in FIG. 2). On the other hand, when the touch pen 10 is removed from the storage unit 9, the storage detection switch 11 is pushed up in the internal direction of the storage unit 9 (direction B in FIG. 2). That is, the storage detection switch 11 detects that the touch pen 10 has been taken out by being pushed up, and the storage detection switch 11 detects that the touch pen 10 has been stored by being pressed down. The state in which the storage detection switch 11 is pushed up is also referred to as an off state, and the state in which the storage detection switch 11 is pressed down is also referred to as an on state.

  FIG. 3 is a schematic diagram illustrating a hardware configuration of the notebook PC 1.

  The notebook PC 1 includes a CPU (Central Processing Unit) 20, a ROM (Read Only Memory) 21, a memory 22, an LCD (Liquid Crystal Display) 23, a graphics adapter 24, a touch sensor 25, an input controller 26, a flash memory 27, and a communication device 28. And a power supply circuit 29, and each part is connected directly or indirectly via a bus 30. The touch panel display 7 includes an LCD 23 and a touch sensor 25.

  The CPU 20 controls the notebook PC 1 as a whole by an OS (Operating System) stored in the flash memory 27, and via the input unit 4, the touch panel display 7, and the like based on various programs stored in the flash memory 27. It has a function of executing processing according to user operations. Further, the CPU 20 receives the detection result of the storage detection switch 11.

  The ROM 21 stores a basic input / output system (BIOS) and various data.

  The memory 22 is composed of a cache memory and a RAM (Random Access Memory), and is a writable memory used as a work area for reading an execution program of the CPU 20 and writing processing data by the execution program.

  The LCD 23 displays the video signal from the graphics adapter 24 as an image under the control of the CPU 20.

  The graphics adapter 24 converts display information into a video signal under the control of the CPU 20 and outputs the converted video signal to the LCD 23.

  The touch sensor 25 detects the contact position of the user's finger and the touch pen 10 on the LCD 23 and outputs the detected position to the input controller 26. The touch sensor 25 selects various menus, icons, buttons, keyboards, and other screen objects displayed on the screen of the LCD 23 to perform input operations, text input operations, screen operations such as scrolling and swiping, and the like. Is performed by the user's finger, the touch pen 10 or the like. As an example, the touch sensor 25 according to the present embodiment detects a contact position by the touch pen 10 by an electromagnetic induction method, and detects a contact position by a finger by a capacitance method. However, the detection method of the contact position by the touch sensor 25 is not limited to this.

  In the following description, an input operation using the touch pen 10 is also referred to as a pen input, and an input operation using a finger is also referred to as a touch input.

  The input controller 26 performs various processes when the processor executes a program stored in the ROM 21 or the like, and controls the operation of the touch sensor 25.

  The flash memory 27 has a function of storing an OS for controlling the entire notebook PC 1, various drivers for hardware operation of peripheral devices, applications directed to specific tasks, various data and files, and the like. Note that the notebook PC 1 may include other storage means such as an HDD (Hard Disk Drive) as storage means in place of the flash memory 27.

  The communication device 28 communicates with other devices.

  The power supply circuit 29 includes an AC adapter, a battery, a charger for charging the battery, a DC / DC converter, and the like, and supplies power to each device under the control of the CPU 20.

  Here, as shown in FIG. 4, when a pen is input to the touch panel display 7, the side of the hand holding the touch pen 10, for example, the side of the palm, the ring finger, the little finger, etc. (area surrounded by the broken line in FIG. 4) May touch the touch panel display 7, and this contact may be recognized as an input to the touch panel display 7 not intended by the user.

  As a result, as shown in FIG. 5, for example, when an image drawing program is started and characters are input by the touch pen 10, in addition to the input by the touch pen 10 intended by the user (input in the area A), An erroneously recognized input (input in the region B) is performed.

  Therefore, in the notebook PC 1 according to the present embodiment, in the pen mode in which the touch pen 10 is used, the touch input sensitivity control that suppresses erroneous input by performing control to reduce the sensitivity of touch input by a finger. It has a function.

  FIG. 6 is a functional block diagram relating to the touch input sensitivity control function according to the present embodiment. The CPU 20 includes a pen mode recognition unit 40, a PR size setting unit 41, and a calibration unit 42. These units included in the CPU 20 are realized by a program.

  The pen mode recognition unit 40 recognizes a pen mode in which the touch pen 10 is used. In the present embodiment, the pen mode recognition unit 40 recognizes that the pen mode is set when the storage detection switch 11 is turned off. As described above, the pen mode is a state in which the user has an intention to use the touch pen 10, such as a state in which the touch pen 10 is taken out from the storage unit 9 as well as the user performing a pen input with the touch pen 10. It is.

  The PR size setting unit 41 sets a PR (Palm Rejection) size. The PR size is a predetermined threshold value of a contact area that the touch on the touch panel display 7 is not an input operation. That is, when there is an input operation with a contact area larger than the PR size, it is assumed that the input operation is a palm (palm) or the like and is not treated as an input operation (so-called palm rejection function). In the following description, a contact area when a finger or the like touches the touch panel display 7 is also referred to as a touch area.

  The PR size is stored in advance in the flash memory 27. In the flash memory 27, as a PR size, a pen mode PR size that is a PR size corresponding to the pen mode, a mode that is not a pen mode, that is, a normal mode corresponding to a mode in which only touch input is performed (hereinafter referred to as “normal mode”). The mode PR size is stored. In the present embodiment, the normal mode is recognized when the storage detection switch 11 is turned on. Further, the PR size stored in the flash memory 27 may be copied (cached) to the memory 22 when the notebook PC 1 is started up, and the PR size copied to the memory 22 may be used in order to improve the processing speed. .

The pen mode PR size is smaller than the normal mode PR size. As an example, the normal mode PR size is 15 cm ^2, and the pen mode PR size is, for example, 1.5 cm to 5 cm on one side, preferably 4 cm ² as an area. As an example, the pen mode PR size is set with the same aspect ratio, while the normal mode PR size is set with the width (finger width direction) longer than the length. Thus, by reducing the pen mode PR size to be smaller than the normal mode PR size, the sensitivity of touch input is reduced when the pen mode PR size is set.

  For example, the normal mode PR size is the same for each user. On the other hand, the pen mode PR size may be a value set for each user or the same for each user.

  Then, when the pen mode recognition unit 40 recognizes the pen mode, the PR size setting unit 41 reads the pen mode PR size from the flash memory 27 (memory 22) and sets it as the PR size. On the other hand, when the pen mode is not recognized (in the normal mode), the PR size setting unit 41 reads and sets a normal mode PR size larger than the pen mode PR size from the flash memory 27 (memory 22). The PR size setting unit 41 outputs the set PR size to the input controller 26. As described above, the PR size setting unit 41 changes the normal mode PR size to the pen mode PR size when the pen mode recognition unit 40 recognizes the pen mode from the normal mode, and then recognizes the normal mode. The pen mode PR size is changed to the normal mode PR size.

  Then, the input controller 26 detects the touch area of the indicator such as the finger or the touch pen 10 on the touch panel display 7 within a predetermined time. When the touch area is larger than the PR size, the input controller 26 touches the indicator within the predetermined time. Functions as an operation determination unit that does not handle the input operation. The predetermined time is a value arbitrarily set in advance, for example, 10 msec seconds.

  Thus, in the pen mode, the CPU 20 reduces the PR size that the touch on the touch panel display 7 is not an input operation compared to the normal mode that is not the pen mode.

  The calibration unit 42 calibrates the pen mode PR size according to the contact state of the user's finger or hand to the touch panel display 7.

  FIG. 7 is a flowchart illustrating a processing flow of the touch input sensitivity control function according to the embodiment. This process starts when the notebook PC 1 is activated. Note that immediately after the notebook PC 1 is activated, the normal mode PR size is set as the PR size.

  First, in step 100, it is determined whether the pen mode recognition unit 40 is in the pen mode. If the determination is affirmative, the process proceeds to step 102. In the case of negative determination, the normal mode is set.

  In the next step 102, the PR size setting unit 41 sets the PR size to the pen mode PR size, thereby changing the PR size from the normal mode PR size to the pen mode PR size having a smaller threshold value. The set pen mode PR size is output to the input controller 26. When step 102 is executed, the PR size is reduced before actually performing the pen input, so that the sensitivity of the touch input is lowered. Therefore, erroneous input due to the side of the hand touching the touch panel display 7 before the pen tip of the touch pen 10 is suppressed. When the pen mode PR size is set for each user, the PR size setting unit 41 reads and sets the pen mode PR size corresponding to the user from the flash memory 27 (memory 22).

  In the next step 104, it is determined whether or not an input operation (pen input) using the touch pen 10 has been started. If the determination is affirmative, the process proceeds to step 106.

  In step 106, acceptance of an input operation (touch input) with a finger is stopped. More specifically, the function of the capacitive touch sensor 25 is stopped.

  In the next step 108, it is determined whether or not a predetermined time has elapsed from the start of the pen input.

  In step 110, the stop of acceptance of touch input is canceled. More specifically, the function of the capacitive touch sensor 25 is resumed. That is, in the case where a negative determination is made in step 108, touch input is not possible, so that erroneous input due to the side surface of the user's hand touching the touch panel display 7 is prevented when pen input is being performed.

  In the next step 112, it is determined whether or not the touch pen 10 is stored in the storage unit 9 by the pen mode recognition unit 40. If the determination is affirmative, the process proceeds to step 114. The case of an affirmative determination is a state in which the normal mode is set. On the other hand, if a negative determination is made, the process returns to step 104.

  In step 114, since the normal mode is set, the PR size setting unit 41 sets the PR size to the normal mode PR size, thereby returning the changed PR size to the normal mode PR size.

  As described above, the notebook PC 1 according to the present embodiment has the touch panel display 7 that accepts an input operation with the touch pen 10 and a finger as an indicator, and the touch area threshold that the touch on the touch panel display 7 is not an input operation. And a flash memory 27 for storing the PR size. When the notebook PC 1 recognizes a pen mode in which the touch pen 10 is used, the notebook PC 1 sets a pen mode PR size that is a PR size corresponding to the pen mode.

  As described above, since the notebook PC 1 according to the present embodiment sets the pen mode PR size corresponding to the pen mode so that the sensitivity to the touch input is reduced when the pen mode is set, the touch pen is used. It is possible to further suppress an erroneous input caused by the fact that the hand holding 10 has touched the touch panel display 7.

  8 and 9 are flowcharts showing the flow of processing relating to the calibration of the pen mode PR size according to the present embodiment, which is executed by the calibration unit 42. The calibration of the pen mode PR size is executed, for example, when a user account for logging in to the notebook PC 1 is set. When the pen mode PR size is calibrated, an image for prompting the user's touch input is appropriately displayed on the touch panel display 7. As the calibration of the pen mode PR size, only one of the processes shown in FIGS. 8 and 9 may be executed, and the user may select which one to execute.

  In the calibration of the pen mode PR size shown in FIG. 8, the maximum touch area between the fingertip and the touch panel display 7 when the user's fingertip touches the touch panel display 7 is changed to the pen mode PR corresponding to the user. Size.

  First, in step 200, the touch area by the touch input of a user's fingertip is acquired. More specifically, when the user continuously moves the finger while touch-inputting the touch panel display 7 with the fingertip, the width of the locus is continuously detected, and the square area with the detected width as one side is the touch area. And

  In the next step 202, it is determined whether or not the acquired maximum value of the touch area has been updated. If the determination is affirmative, the process proceeds to step 204. If the determination is negative, the process proceeds to step 206.

  In step 204, the updated maximum value of the touch area is stored in the flash memory 27 as the pen mode PR size corresponding to the user, and the process proceeds to step 206.

  In step 206, it is determined whether or not a predetermined time (for example, 30 seconds) has elapsed. If the determination is affirmative, the calibration of the pen mode PR size is terminated. On the other hand, in the case of negative determination, the process returns to step 200 and prompts the user to continuously move the finger while performing touch input until a predetermined time has elapsed.

  The calibration of the pen mode PR size shown in FIG. 9 is performed between the side surface of the user's hand and the touch panel display 7 when pen input is performed with the touch pen 10 while the side surface of the user's hand is in contact with the touch panel display 7. The minimum value of the touch area is set as the pen mode PR size corresponding to the user.

  First, in step 300, a touch area obtained by the side surface of the user's hand touching the touch panel display 7 is acquired. More specifically, the touch area between the side surface of the user's hand and the touch panel display 7 is continuously detected when the user performs pen input while bringing the side surface of the user's hand into contact with the touch panel display 7. .

  In the next step 302, it is determined whether or not the acquired minimum value of the touch area has been updated. If the determination is affirmative, the process proceeds to step 304. If the determination is negative, the process proceeds to step 306.

  In step 304, the updated minimum value of the touch area is stored in the flash memory 27 as the pen mode PR size corresponding to the user, and the process proceeds to step 306.

  In step 306, it is determined whether or not a predetermined time (for example, 30 seconds) has elapsed. If the determination is affirmative, the calibration of the pen mode PR size is terminated. On the other hand, in the case of a negative determination, the process returns to step 300 and prompts the user to perform pen input while touching the touch panel display 7 with the side surface of the user's hand until a predetermined time has elapsed.

  In this way, by calibrating the pen mode PR size for each user, even if the pen mode PR size is set and the sensitivity of the touch input is lowered, it is possible to suppress the user's touch input operation feeling from being lowered. .

In the case of this form, for example, the storage detection switch 11 is provided in the pen holder, and the detection result of the storage detection switch 11 is input to the notebook PC 1 via the USB.

  Moreover, although the pen mode recognition part 40 demonstrated the form which recognizes pen mode based on the detection result by the storage detection switch 11 in the said embodiment, this invention is not limited to this. For example, when the touch panel display 7 displays an image indicating the start of the pen mode and the user touches the image, the pen mode recognition unit 40 may recognize the pen mode. Further, the touch pen 10 is provided with a sensor for detecting that the user is gripped by the user or a switch operated by the user.
