  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a virtual sticky note input display system S, which is a display object input display system in the present embodiment, and a handwritten input memo pad 1 connected to each other so as to be able to send and receive information to each other, and a personal computer 200 (hereinafter, PC 200). Abbreviated). The handwriting input memo pad 1 is an operation terminal that allows a user to manually write on a sheet using an electronic pen described later and to electronically input the handwritten writing content. The PC 200 is a computer having a general configuration including a display unit 201 as a display unit and a main body 202. The PC 200 is an information processing device that processes a virtual sticky note application, which will be described later. Based on the operation information input from the handwritten input memo pad 1, the PC 200 is a virtual sticky note as a display object on the display screen of the display unit 201. Performs various types of paper control. In the illustrated example, the handwritten input memo pad 1 and the PC 200 are connected via a wired cable so as to be able to send and receive information, but may be connected via a wireless network.

  As shown in FIGS. 2A and 2B, the handwritten input memo pad 1 includes an electronic pen 2 that is an electronic writing instrument and a memo pad device 3. In the handwriting input memo pad 1, the user holds the electronic pen 2. The electronic pen 2 is for inputting data corresponding to writing contents on a memo paper, which will be described later, and functions as an input means for position information, that is, coordinate data, in addition to a function as a writing instrument.

  As shown in FIGS. 2A and 2B, the memo pad device 3 has a memo pad main body 10 that is disposed on the back side of a memo paper 11 described later and fixed integrally therewith. Inside the memo pad body 10, a coil sheet 100 having a size substantially the same as that of the memo pad body 10 is provided.

  In the example shown in the drawing, a plurality of memo papers 11 as writing instruments, which are stacked so that the upper side is closed and can be turned up from the lower side, are arranged so as to overlap the front side of the memo pad main body 10.

  The user writes a desired handwritten character string or the like on the writing surface of the memo paper 11 using the electronic pen 2. By the movement of the electronic pen 2 corresponding to the writing operation, electronic input information corresponding to the written content, that is, a pen position data string described later is stored in the electronic file. At that time, in the same way as writing is actually performed while turning a page on the writing surface of the memo paper 11 using ink, a page turning detection unit to be described later automatically detects a page turning operation, so that the electronic file It is possible to save while performing page switching (page advance or page return).

  When the user uses the handwriting input memo pad 1, a power switch (not shown) provided in the electronic pen 2 is turned on. As shown in FIGS. 3 and 4, the electronic pen 2 includes a pen tip 2 a that is a direct writing tool provided at the tip, a permanent magnet 47, an LC oscillation circuit 41 including a coil 44 and a capacitor 45, a tip A switch 42, a control unit 46 that controls the entire electronic pen 2, a control board 40 on which the capacitor 45 is disposed, and a battery 43 are included. The means for generating the magnetic field is not limited to the oscillation circuit such as the LC oscillation circuit 41, and may be a resonance circuit.

  The tip switch 42 operates according to the contact state of the nib 2 a with the memo paper 11 and outputs a command signal S 0 for changing the frequency of an alternating magnetic field (described later) generated from the coil 44 to the control unit 46. It is a switch to do. The tip switch 42 is turned on when the user presses the pen tip 2a against the memo paper 11 (pen down) for writing a character or the like. In this case, a command signal S0 is output to the control unit 46. On the other hand, it is turned off when the user stops writing of characters or the like and separates the pen tip 2a from the memo paper 11 (pen-up). In this case, the command signal S0 is not output to the control unit 46.

  The LC oscillation circuit 41 is a circuit for generating and outputting an alternating magnetic field (hereinafter, simply referred to as “magnetic field” as appropriate) which is a position signal for detecting a moving position. The coil 44 of the LC oscillation circuit 41 is disposed so as to be wound around the permanent magnet 47 and is electrically connected to the capacitor 45 to generate a magnetic field generated by the LC oscillation circuit 41. The frequency of the magnetic field generated from the coil 44 by the LC oscillation circuit 41 is changed by changing the capacitance of the capacitor 45 based on control by the control unit 46 according to whether the tip switch 42 is turned on or off. That is, when the tip switch 42 is on, the control unit 46 to which the command signal S0 is input controls the LC oscillation circuit 41 so as to generate a magnetic field having a specific frequency f1 from the coil 44. On the other hand, when the tip switch 42 is OFF, the control unit 46 to which the command signal S0 is not input controls the LC oscillation circuit 41 so as to generate a magnetic field having a specific frequency f2 from the coil 44.

  Hereinafter, as appropriate, the frequency f1 of the magnetic field generated from the coil 44 when the tip switch 42 is on is referred to as “contact frequency f1”, and the frequency f2 of the magnetic field generated from the coil 44 when the tip switch 42 is off. Is referred to as "separation frequency f2." The magnetic field generated from the coil 44 is detected by the memo pad body 10. By setting f1> f2, it is possible to reduce the power consumption of the electronic pen 2 when generating a magnetic field having a separation frequency f2.

  The battery 43 supplies power to the control unit 46, the LC oscillation circuit 41, and the like when the power switch of the electronic pen 2 is turned on.

  On the other hand, the memo pad body 10 includes a coil sheet 100 and a control circuit unit 20 as shown in FIG. The coil sheet 100 and the control circuit unit 20 are connected via a signal line.

  The coil sheet 100 includes a sense coil unit 110 as shown in FIG. That is, as shown in FIG. 5, the sense coil portion 110 arranged as shown in FIG.

  As shown in FIG. 5, the sense coil unit 110 includes m loop-shaped sense coils X1 to Xm arranged in the x-axis direction and n loop-shaped sense coils Y1 to Ym arranged in the y-axis direction. Yn. Each of the m sense coils X1 to Xm and the n sense coils Y1 to Yn constituting the sense coil unit 110 is a coil that can receive the magnetic field generated by the coil 44 of the electronic pen 2, respectively. It corresponds to a plurality of coils described in each claim. The sense coils X1 to Xm and the sense coils Y1 to Yn are arranged in a positional relationship orthogonal to each other. In addition, the coil surfaces of the sense coils X1 to Xm and Y1 to Yn are substantially parallel to the direction of the writing surface of the memo paper 11. Further, the sense coils X1 to Xm and Y1 to Yn are formed of, for example, copper wires having an insulating coating layer formed on the surface. Still further, the sense coils X1 to Xm, Y1 to Yn are connected to a multiplexer 62 (to be described later) by a lead line not shown and described. Then, the scan process of the sense coil unit 110 is started, and the sense coils X1 to Xm and Y1 to Yn receive the magnetic field generated by the coil 44 of the electronic pen 2, in other words, the sense coils X1 to Xm and Y1. Electromotive force is generated in the sense coils X1 to Xm and Y1 to Yn due to electromagnetic induction between ~ Yn and the magnetic field generated by the coil 44. That is, the sense coils X1 to Xm and Y1 to Yn generate a signal S1 (see FIG. 4) by magnetic coupling with the coil 44.

  Each of the sense coils X1 to Xm is formed in a substantially rectangular shape including a side having a width P1 in the x-axis direction and a side having a length P2 in the y-axis direction longer than P1. Each of the sense coils X1 to Xm is arranged continuously in the x-axis direction at a predetermined constant pitch. For example, the adjacent sense coils X1 to Xm are overlapped with each other at a half pitch of P1.

  Each of the sense coils Y1 to Yn is formed in a substantially rectangular shape having a side having a width P3 in the x-axis direction and a side having a length P1 in the y-axis direction shorter than P3. Each of the sense coils Y1 to Yn is continuously arranged in the y-axis direction at a predetermined constant pitch. For example, the adjacent sense coils Y1 to Yn are overlapped at a pitch of 1/2 of P1.

  In FIG. 5, for the sake of convenience, the sides of the sense coils X1 to Xm and the sense coils Y1 to Yn are not overlapped for the sake of convenience. Not. In FIG. 5, the shape of the sense coils X <b> 1 to Xm, Y <b> 1 to Yn is illustrated by omitting a lead line entering the multiplexer 62 described later.

  Returning to FIG. 4, the control circuit unit 20 includes a microcomputer 80, a multiplexer 62 (hereinafter referred to as “MUX 62” as appropriate), an amplifier circuit 64, a rectifier circuit 66, a limiter 68, a communication interface 69, and a flash memory. 70 and a page turning detection unit 71.

  The microcomputer 80 includes a CPU 80a, a ROM 80b, a RAM 80c, and other A / D conversion function units, interrupt function units, and the like as one integrated circuit. The microcomputer 80 controls various processes executed by the memo pad main body 10 and controls the operation states of other peripheral circuits.

  The MUX 62 selects the sense coils X1 to Xm and Y1 to Yn of the sense coil unit 110 one by one based on the coil selection signal S3 from the microcomputer 80. The MUX 62 receives the signal S1 generated in the selected sense coils X1 to Xm, Y1 to Yn, and outputs a corresponding signal S11 to the amplifier circuit 64.

  The amplifier circuit 64 amplifies the signal S11 input from the MUX 62. The signal S12 amplified by the amplifier circuit 64, that is, the electronic pen input detection signal S12 is input to the limiter 68. The limiter 68 processes the signal S12 input from the amplifier circuit 64 into a digital signal S15 having only frequency and phase information, and inputs it to the interrupt input of the microcomputer 80. The microcomputer 80 determines the frequency of the signal S1 from the sense coils X1 to Xm and Y1 to Yn by measuring the period of the signal S15 input from the limiter 68 with a timer or the like, and senses currently being scanned. The data is stored in the RAM 80c together with the coil numbers of the sense coils X1 to Xm and Y1 to Yn of the coil unit 110.

  Another signal S13 amplified by the amplifier circuit 64 is input to the rectifier circuit 66. The rectifier circuit 66 amplitude-detects the signal S13 input from the amplifier circuit 64, smoothes it, and converts it into a DC signal. The signal S14 subjected to amplitude detection by the rectifier circuit 66 is input to the microcomputer 80. As described above, the microcomputer 80 has an A / D conversion function, and converts the input signal S14 after amplitude detection into a digital signal. At this time, the ROM 80b of the microcomputer 80 stores the detection levels of the sense coils X1 to Xm and Y1 to Yn and the offset value of the coordinate data of the contact point between the electronic pen 2 and the memo paper 11 in association with each other. A coordinate table is stored (detailed description is omitted). The microcomputer 80 calculates the position information of the electronic pen 2, that is, the x coordinate in the x axis direction and the y coordinate in the y axis direction, by applying a position coordinate table to the digital signal. The calculated position information is stored in the flash memory 70 of the peripheral circuit 70 described later. A set of these calculated pieces of position information constitutes stroke data input by handwriting by the user.

  Further, the microcomputer 80, based on the coil numbers of the maximum output sense coils X1 to Xm and Y1 to Yn, stored in the RAM 80c during the scan process of the sense coil unit 110, the sense coils X1 to Xm, The frequency of the signal S1 obtained from Y1 to Yn is detected. Thereby, the frequency value f of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn represented by the coil numbers is detected.

  The communication interface 69 transmits various kinds of information such as stroke data including a plurality of position information stored in the flash memory 70 and pen contact state information described later to the PC 200, and receives predetermined information from the PC 200. It is an interface for. Specifically, the communication interface 69 is, for example, a USB interface for Universal Serial Bus (USB) connection or a wireless or wired network interface.

  An electronic file is prepared in advance in the flash memory 70, and stroke data based on a plurality of pieces of position information calculated by the microcomputer 80 is written and stored in the electronic file.

  Each time the user actually changes the page of the memo paper 11, the page turning detection unit 71 detects and inputs the switching of the page number corresponding to the change of the page. As a specific method of detecting this page turning, for example, a method of detecting a sound accompanying a page turning operation with an audio microphone, a method of optically reading a barcode or the like previously described on each page, and the like can be used.

(A) Principle of Method for Detecting Pen Separation State in the Present Embodiment Here, based on the frequency aspect of the magnetic field received by the sense coils X1 to Xm, Y1 to Yn, the 3 of the electronic pen 2 with respect to the writing surface of the note paper 11 A method for determining a state of separation / contact will be described. As described above, when the position information of the electronic pen 2 is detected, the sense coils X1 to Xm and Y1 to Yn are sequentially selected in a predetermined cycle, and the selected sense coils X1 to Xm and Y1 to Yn are selected. The position information of the electronic pen 2 is calculated based on the reception result of the magnetic field. At the same time, the frequency value f of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn is detected based on the reception result of the magnetic field by the selected sense coils X1 to Xm and Y1 to Yn. It is also determined whether the frequency value f is the contact frequency f1 or the separation frequency f2, whether the detected frequency value f is in an indefinite state, or the like.

  That is, when the user is writing on the writing surface of the memo paper 11 using the electronic pen 2, magnetic fields generated by the electronic pen 2 are received by the sense coils X1 to Xm and Y1 to Yn. Based on the reception result, the position information of the electronic pen 2 is calculated. Thereby, stroke data including a plurality of pieces of position information representing the movement locus of the electronic pen 2 corresponding to the writing operation when the user writes on the writing surface is generated.

  While the user performs a writing operation using the electronic pen 2 in this manner, the pen-down state in which the tip 2 is brought into contact with the writing surface of the memo paper 11 and the tip switch 42 is turned on, The pen-up state in which the pen tip 2a of the pen 2 is slightly separated from the writing surface of the memo paper 11 and the tip switch 42 is turned off is frequently switched. In such a case, the frequency value f of the magnetic field received by the sense coils X1 to Xm, Y1 to Yn is the contact frequency f1 when the electronic pen 2 is in the pen down state (when the tip switch 42 is on). When the electronic pen 2 is in the pen-up state (when the tip switch 42 is off), the separation frequency f2 is obtained.

  Besides performing the writing operation as described above, the user moves the electronic pen 2 along the writing surface while maintaining the pen-up state in which the electronic pen 2 is slightly separated from the memo paper 11. Is received by the sense coils X1 to Xm, Y1 to Yn, and the position information of the electronic pen 2 can be calculated based on the reception result.

  Further, when the electronic pen 2 is in the pen-down state or the pen-up state described above, it is received by the sense coils X1 to Xm, Y1 to Yn or the proximity detection coil 121 as shown in FIG. The frequency value f of the applied magnetic field is in a constant state. On the other hand, there are cases where the user places the electronic pen 2 far away from the sense coils X1 to Xm, Y1 to Yn, that is, places the electronic pen 2 far away from the writing surface of the memo paper 11. In this case, the magnetic coupling state between the coil 44 of the electronic pen 2 and the sense coils X1 to Xm, Y1 to Yn changes, and the resonance frequency becomes indefinite. As a result, the frequency aspect of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn changes. That is, when the electronic pen 2 is greatly separated from the sense coils X1 to Xm and Y1 to Yn, the frequency of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn as shown in FIG. The value f becomes indefinite.

  Thereby, in the handwritten input memo pad 1 of the present embodiment, when the memo pad device 3 detects the position information of the electronic pen 2, the microcomputer 80 determines whether or not the detected frequency value f is in an indefinite state. By doing so, it is determined whether or not the electronic pen 2 is in a so-called pen-free state in which the electronic pen 2 does not exist in the vicinity of the memo pad device 3 with a large distance from the sense coils X1 to Xm and Y1 to Yn. That is, when the detected frequency value f of the magnetic field is in an indefinite state, it is determined that the electronic pen 2 is in a pen-free state that is largely separated from the sense coils X1 to Xm and Y1 to Yn.

  As described above, in the handwritten input memo pad 1 of the present embodiment, when the memo pad device 3 detects the position information of the electronic pen 2, the microcomputer 80 is based on the reception results of the magnetic fields in the sense coils X1 to Xm and Y1 to Yn. The frequency value f of the magnetic field is detected. Then, as shown in FIG. 7, when the frequency mode as the output mode of the detected magnetic field, that is, when the frequency value f is the contact frequency f1, it is determined that the electronic pen 2 is in the pen-down detached state. When the detected frequency value f is the separation frequency f2, it is determined that the electronic pen 2 is in the pen-up separation state, and when the detected frequency value f is indefinite, It is determined that the pen 2 is in the no pen state. The pen-down state corresponds to the contact state described in each claim, and the pen-up state corresponds to the separated state described in each claim.

  The output voltage value V generated by the magnetic field received by the sense coils X1 to Xm and Y1 to Yn is generally the distance between the coil 44 of the electronic pen 2 and the sense coils X1 to Xm and Y1 to Yn. Dependent. That is, the closer the distance between the coil 44 of the electronic pen 2 and the sense coils X1 to Xm, Y1 to Yn, the greater the generated output voltage value V, and vice versa. The output voltage value V decreases. Accordingly, when the electronic pen 2 is separated from the writing surface of the memo paper 11 as described above, the coil 44 of the electronic pen 2 and the sense coils X1 to Xm and Y1 to Yn are magnetically coupled. Since the state is not reached, the generated output voltage value V is very small or substantially zero. Focusing on this point, based on the output mode of the magnetic field received by the proximity detection coil 121, the electronic pen 2 is far away from the sense coils X1 to Xm, Y1 to Yn, that is, the above-mentioned pen-less state is established. It may be determined whether or not.

(B) Usage Form of the Present Embodiment in the Virtual Sticky Note Application In the virtual sticky note input display system S of the present embodiment, a display example in the display unit 201 of the virtual sticky note application processed by the PC 200 is shown in FIG. In the example shown, five virtual sticky notes 301 to 305 are created and pasted and displayed at positions arbitrarily designated by the user in the display area of the display unit 201. Each of the virtual sticky notes 301 to 305 is formed in a rectangular shape having a predetermined size, and stroke data input by handwriting is entered in the handwritten input memo pad 1. Each stroke data in the illustrated example is entered as a character string consisting of a plurality of characters, but in addition to that, a figure or the like arbitrarily written by the user can be entered as stroke data.

  In addition, the size of each virtual sticky note can be adjusted and changed as appropriate according to the length and size of the stroke data, or the display position can be moved to an arbitrary position, or unnecessary ones can be deleted. it can. The user designates an arbitrary position using the cursor 310 that can be freely moved and displayed on the display area. By using such a virtual sticky note application, the user can temporarily display fragmentary information on the display screen of the PC 200 in a free writing manner by handwriting input.

  In the virtual sticky note input display system S of the present embodiment, the cursor 310 moving operation, the existing virtual sticky note moving operation, and the input of a new virtual sticky note can be performed only by using the handwritten input memo pad 1. Any of the creation operations can be performed intuitively. Hereinafter, details of each operation will be described in order.

  First, when performing the cursor movement operation, as shown in FIG. 9, the electronic pen 2 is moved along the writing surface of the memo paper 11 while maintaining the detached state of the electronic pen 2 in the pen-up state. The cursor 310 on the display screen can be moved and displayed in response to the movement of the screen. In this case, the cursor 310 may be moved according to the relative movement amount and movement direction of the electronic pen 2. Thereby, even if the effective area coordinates of the sense coil unit 110 and the display area coordinates of the display screen do not correspond one-to-one, it is possible to move to any position. That is, even when the movement of the electronic pen 2 does not fit within the effective area of the sense coil unit 110 during the movement operation of the cursor 310, the electronic pen 2 is lifted once to be in a no-pen state and then into the effective area of the sense coil unit 110. The movement of the cursor 310 can be continued by moving and restarting the movement after returning to the pen-up state again. This is the same operation as a mouse generally used as a pointing device.

  Note that the operation for moving the existing virtual sticky note and the input creation operation for the new virtual sticky note described above are switched depending on the display content of the position of the cursor 310 when the pen is moved down from the state of the cursor moving operation. In other words, with the cursor movement operation described above as a basic mode, when the cursor 310 is overlaid on an existing virtual sticky note in the display area of the display unit 201 and the pen is down, the mode is such that the existing virtual sticky note is operated. One mode is switched to a mode for performing a moving operation, and when the cursor 310 is located outside an existing virtual sticky note, the mode is switched to a mode for performing an input creation operation for a new virtual sticky note.

  Here, the case of moving the existing virtual sticky note paper will be described with reference to FIG. First, as described above, during the cursor movement mode, when the electronic pen 2 is penned down with the cursor 310 in the display area of the display unit 201 positioned in the existing area of the existing virtual sticky note 304, The virtual sticky note moving mode for moving the existing virtual sticky note 304 is switched. In addition, after switching the virtual sticky note moving mode, the electronic pen 2 is immediately returned to the pen-up state. At this time, the existing virtual sticky note 304 to be moved is displayed in a mode different from the other virtual sticky notes 301, 302, 303, and 305 by, for example, the highlighted display shown in the figure (FIG. 10A). reference). The virtual sticky note moving mode corresponds to the display object moving mode described in each claim. The virtual sticky note movement mode is positioned as one of various execution modes included in the virtual sticky note operation mode (equivalent to the display object operation mode described in each claim). In the example of the present embodiment, The virtual sticky note operation mode executes only the virtual sticky note movement mode.

  Next, as shown in FIG. 10B, the electronic pen 2 is moved along the writing surface of the memo paper 11 while maintaining the detached state of the electronic pen 2 in the pen-up state, thereby corresponding to the movement of the electronic pen 2. The cursor 310 on the display screen and the existing virtual sticky note 304 to be moved are moved and displayed together. At this time, since the electronic pen 2 is in the pen-up state, the locus of movement of the electronic pen 2 does not remain on the writing surface of the memo paper 11.

  When the existing virtual sticky note 304 to be moved is moved to an arbitrary destination, the user performs a pen-down and a pen-up again as shown in FIG. The sticky note movement mode is terminated. At this time, the display of the virtual sticky note 304 is also returned from the highlight display to the normal display.

  After that, returning to the cursor movement mode and moving the electronic pen 2 along the writing surface of the memo paper 11 while maintaining the pen-up state, only the cursor 310 on the display screen can be displayed. 10 (d)).

  Next, a case where a new virtual sticky note is input and created will be described with reference to FIG. First, as described above, while the cursor 310 in the display area of the display unit 201 is positioned outside the existing area of the existing virtual sticky notes 301 to 305 during the cursor movement mode, the electronic pen 2 is penned down. When writing input is started, the mode is switched to the virtual sticky note input creation mode (see FIG. 11A). The virtual sticky note input creation mode described above corresponds to the display object input creation mode described in each claim.

  Next, as shown in FIG. 11 (b), stroke data to be written on a new virtual sticky note is written and input to the memo pad device 3 with the electronic pen 2. At this time, the user can write while visually observing the actual description on the writing surface of the memo paper 11 ("idea" in the illustrated example). Further, during the writing input, the electronic pen 2 frequently repeats the pen-down state and the pen-up state at short time intervals.

  Then, when the pen-up state continues for a predetermined time, which is a long time that can be determined that the writing input has been completed, the virtual sticky note input creation mode is ended, and the display as shown in FIG. A new virtual sticky note 306 in which the stroke data is written is pasted and displayed at the position of the cursor 310 on the display area of the part 201.

  After that, returning to the cursor movement mode and moving the electronic pen 2 along the writing surface of the memo paper 11 while maintaining the pen-up state, only the cursor 310 on the display screen can be displayed. 10 (d)).

(C) Control processing of this embodiment In order to realize the functions as described above, the contents of the control processing performed by the CPU 80a of the memo pad body 10 and the CPU (not shown) of the PC 200 are shown in FIG. 13 will be described step by step.

  In FIG. 12, the processing of the CPU 80a of the memo pad main body 10 shown in this flow is started when the user turns on the power of the memo pad main body 10, for example. At the start of this flow, it is assumed that the electronic pen 2 is in a disconnected state without a pen. First, in step SS5, the CPU 80a detects the contact / disconnection state of the electronic pen 2 based on the frequency mode of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn. That is, the state of separation / contact of the electronic pen 2 at that time is detected by the above-described method principle (A).

  Then, the process proceeds to step SS10, and the CPU 80a determines whether or not the separated state detected in step SS5 is a pen-up state. That is, it is determined whether or not the frequency f of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn is the separation frequency f2. If the separated state detected in step SS5 is a pen-up state, the determination is satisfied, and the routine goes to step SS15.

  In step SS15, the CPU 80a, based on the detection levels of the magnetic fields received by the sense coils X1 to Xm and Y1 to Yn in step SS5 and the position coordinate table described above, the effective coordinates of the sense coil unit 110 at that time point. The coordinate position of the electronic pen 2 in the area is calculated.

  In step SS20, the CPU 80a transmits pen-up information indicating that the electronic pen 2 is in the pen-up state and pen position information indicating the coordinate position calculated in step SS15 to the PC 200. And it returns to step SS5 and repeats the same procedure.

  On the other hand, if it is determined in step SS10 that the disengagement state detected in step SS5 is not a pen-up state, the determination is not satisfied and the process proceeds to step SS25.

  In Step SS25, the CPU 80a determines whether or not the separation / contact state detected in Step SS5 is a pen-down state. That is, it is determined whether or not the frequency f of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn is the contact frequency f1. If the separated state detected in step SS5 is a pen-down state, the determination is satisfied, and the routine goes to step SS30.

  In step SS30, the CPU 80a calculates the coordinate position of the electronic pen 2 by the same process as in step SS15.

  Then, the process proceeds to step SS35, and the CPU 80a transmits pen down information indicating that the electronic pen 2 is in the pen down state and pen position information indicating the coordinate position calculated in step SS30 to the PC 200. And it returns to step SS5 and repeats the same procedure.

  On the other hand, if it is determined in step SS25 that the separated state detected in step SS5 is not a pen-down state, the determination is not satisfied, and the process proceeds to step SS40.

  In step SS40, the CPU 80a transmits to the PC 200 only the penless information indicating that the electronic pen 2 is in the penless state. And it returns to step SS5 and repeats the same procedure.

  By executing the above flow, the memo pad main body 10 continuously transmits any one of the pen-down information, the pen-up information, and the pen-less information to the PC 200, and the pen-down information and the pen-up information are included. When transmitting, the pen position information is also transmitted.

  Next, the contents of the control process performed by the CPU of the PC 200 will be described in order with reference to FIG. In FIG. 13, the processing of the CPU of the PC 200 shown in this flow is started, for example, when the user operates the PC 200 to activate the virtual sticky note application. Also, at the start of this flow, it is assumed that the electronic pen 2 is in the state of no contact with the pen. First, in step SS105, the CPU determines whether pen-up information has been received from the memo pad body 10. A loop is waited until pen-up information is received from the memo pad body 10, and when pen-up information is received, the process proceeds to step SS110.

  In step SS110, the CPU performs movement display of the cursor 310 corresponding to the relative change in the pen position information based on the pen position information received together with the pen-up information in step SS105. The procedure of step SS110 corresponds to a specific process in the cursor movement mode.

  Then, the process proceeds to step SS115, and the CPU determines whether pen-less information has been received from the memo pad body 10. If pen-less information is received from the memo pad body 10, the determination is satisfied, and the process returns to step SS105 to repeat the same procedure.

  On the other hand, if the penless information is not received, the determination is not satisfied, and the routine goes to Step SS120.

  In step SS120, the CPU determines whether pen-down information has been received from the memo pad body 10. If pen-down information has not been received from the memo pad body 10, the determination is not satisfied, and the routine returns to step SS110 and the same procedure is repeated. While repeating the above steps SS105 to SS120, the user can move the cursor 310 to an arbitrary position on the display area of the display unit 201 of the PC 200.

  On the other hand, if it is determined in step SS120 that the pen down operation is received from the memo pad body 10 by the user performing a pen down operation, the process proceeds to step SS125.

  In step SS125, the CPU detects the display content at the current position of the cursor 310 on the display area of the display unit 201.

  Then, the process proceeds to step SS130, and the CPU determines whether or not the display content detected in step SS125 is an existing virtual sticky note. In other words, it is determined whether or not the current position of the cursor 310 is within the existing area of the virtual sticky note. If the display content detected in step SS125 is an existing virtual sticky note, the determination is satisfied, and the routine goes to step SS135.

  In step SS135, the CPU determines whether pen-up information has been received from the memo pad body 10. A loop is waited until pen-up information is received from the memo pad body 10, and when pen-up information is received, the process proceeds to step SS140. In the example of the present embodiment, when a pen-up operation is detected following the pen-down operation in the cursor movement mode, the virtual sticky note movement mode is switched.

  In step SS140, based on the pen position information received together with the pen-up information in step SS135, the cursor 310 and the virtual sticky note corresponding to the relative change in the pen position information are displayed. Note that the existing virtual sticky note to be moved is detected from the cursor position in step SS125, and in this example, the existing virtual sticky note is highlighted. The procedure of step SS110 corresponds to a specific process in the virtual sticky note moving mode.

  Then, the process proceeds to step SS145, and the CPU determines whether pen-less information has been received from the memo pad body 10. If pen-less information is received from the memo pad body 10, the determination is satisfied, and the process returns to step SS135 to repeat the same procedure.

  On the other hand, if the penless information is not received, the determination is not satisfied, and the routine goes to Step SS150.

  In step SS150, the CPU determines whether pen-down information has been received from the memo pad body 10. If the pen-down information has not been received from the memo pad body 10, the determination is not satisfied and the routine returns to Step SS140 and the same procedure is repeated. While repeating the above steps SS135 to SS150, the user can move the cursor 310 and the virtual sticky note to be moved to an arbitrary position on the display area of the display unit 201 of the PC 200.

  On the other hand, if it is determined in step SS150 that the pen down information has been received from the memo pad body 10 due to the user performing a pen down operation, the process proceeds to step SS155.

  In step SS155, the CPU returns the existing virtual sticky note paper that has been the object of movement from the above-described highlight display to the normal display, and fixedly displays it at the position at that time. And it returns to said step S105 and repeats the same procedure. At this time, when a pen-up operation is detected subsequent to the pen-down operation, the cursor movement mode is switched again.

  On the other hand, if it is determined in step SS130 that the display content detected in step SS125 is other than the existing virtual sticky note, the determination is not satisfied, and the process proceeds to step SS160.

  In step SS160, the CPU stores the position (xp, yp) of the cursor 310 at that time in the display area of the display unit 201.

  Then, the process proceeds to step SS165, where the CPU accumulates the pen position information received together with the pen down information from the memo pad body 10 at that time, and generates stroke data based on the pen position information. The procedure of step SS165 corresponds to a specific process in the virtual sticky note input creation mode.

  Then, the process proceeds to step SS170, and the CPU determines whether pen-up information has been received from the memo pad body 10. If the penless information is not received from the memo pad main body 10, the determination is not satisfied and the routine returns to Step SS165 and the same procedure is repeated. While the above steps SS165 to SS170 are repeated, the user can input stroke data for one stroke or one stroke written in characters.

  On the other hand, if pen-up information is received, the determination is satisfied, and the routine goes to Step SS175.

  In step SS175, the CPU resets the value of the timer counter T to zero.

  Then, the process proceeds to step SS180, and the CPU determines whether pen-down information has been received from the memo pad body 10. If pen-down information is received from the memo pad body 10, the determination is satisfied, and the routine returns to step SS165 to repeat the same procedure.

  On the other hand, if the pen-down information has not been received, the determination is not satisfied and the routine goes to Step SS185.

  In step SS185, the CPU increments the value of the timer counter T by one.

  Then, the process proceeds to step SS190, and the CPU determines whether or not the value of the timer counter T is greater than a predetermined value T1. In other words, it is determined whether or not the pen-up state has continued in such a long time that it can be determined that the user's writing input has been completed. If the value of the timer counter T is equal to or less than the predetermined value T1, the determination is not satisfied, the process returns to step SS180, and the same procedure is repeated.

  On the other hand, when the value of the timer counter T is larger than the predetermined value T1, the determination is satisfied, and the routine goes to Step SS195.

  In step SS195, the CPU creates a new virtual sticky note in which the stroke data generated in step SS165 is entered, and corresponds to the cursor position (xp, yp) stored in step SS160 in the display area of the display unit 201. Affixed to the position. And it returns to step SS105 and repeats the same procedure. At this time, when the pen-up operation is detected in step SS105, the mode is again switched to the cursor movement mode.

  In the above, the procedure of step SS15 and step SS25 in the flow of FIG. 12 corresponds to the position detection means described in each claim, the procedure of step SS5 corresponds to the separated state detection means, and the step in the flow of FIG. The procedure of SS110 corresponds to the cursor movement display means described in each claim, the procedure of steps SS135 to SS155 corresponds to the display object operation mode, the procedure of step SS140 corresponds to the display object movement mode execution means, and step SS160. Step SS195 corresponds to the display object input creation mode, step SS165 corresponds to the display object input creation mode execution means, and step SS130 corresponds to the mode switching means. In the example of this embodiment, the specific execution mode included in the display object operation mode is only the display object movement mode, that is, the display object movement described in each claim is performed without changing the procedure from step SS135 to step SS155. It corresponds to the mode.

  As described above, in the virtual sticky note input display system S of the present embodiment, the procedure of step SS5 is based on the output mode of the position signals received by the sense coils X1 to Xm and Y1 to Yn. The pen-down state and the pen-up state between the memo paper 11 and the memo paper 11 are detected, and the procedure of step SS15 and step SS25 detects the position information of the electronic pen 2 in each state.

  While the electronic pen 2 is in the pen-up state, the procedure of step SS110 moves and displays the cursor 310 in the display area of the display unit 201 in accordance with the position information of the electronic pen 2. Then, when the electronic pen 2 comes into contact with the memo paper 11 and enters the pen-down state, the procedure of step SS130 includes a virtual sticky note operation mode for performing various operations on the existing virtual sticky note paper, and a new virtual Switch to one of the virtual sticky note input creation modes for creating a sticky note and inputting stroke data in the sticky note. In this mode switching destination determination, the coordinate position in the display area corresponding to the position information of the electronic pen 2 when the pen-up state is detected, that is, the position of the cursor 310 is within the existing virtual sticky note existing area. Is switched to the virtual sticky note operation mode, and when it is outside the existing virtual sticky note existing area, the virtual sticky note input creation mode is switched. In the example of the present embodiment, the existing virtual sticky note paper is moved by switching directly to the only virtual sticky note moving mode that can be executed in the virtual sticky note operation mode.

  As described above, according to the present embodiment, the electronic pen 2 can be used as both the pointing device and the stroke data input device, and the operation necessary for the virtual sticky note application, that is, the movement operation of the cursor 310, the new virtual All the input creation of sticky notes and the movement operation of the existing virtual sticky notes can be performed intuitively. As a result, the interface devices used for the virtual sticky note application can be integrated into one electronic pen 2, and the convenience for the user can be improved.

  Note that the PC 200 may collectively execute the procedures of the flows of both FIG. 12 and FIG. In this case, although not specifically illustrated, for example, the microcomputer 80 in FIG. 4 controls only the coil selection signal S3 according to the request signal from the PC 200, and transmits the signal S14 and the signal S15 to the PC 200 as they are. Then, the PC 200 executes both the flow in FIG. 12 and FIG. 13 in parallel by time-division processing, or executes the flow in FIG. 12 every time the connection state information is requested in the flow in FIG. .

  In this case, the procedure of step SS15 and step SS25 in the flow of FIG. 12 corresponds to the position detection procedure described in each claim, the procedure of step SS5 corresponds to the disconnected state detection procedure, and the flow of FIG. The procedure of step SS110 corresponds to the cursor movement display procedure described in each claim, and the procedure of step SS130 corresponds to the mode switching procedure.

  Also with the above configuration, the same effect as in the above embodiment can be obtained.

  In the present embodiment, in particular, the procedure of step SS140 moves the existing virtual sticky note to the coordinate position in the display area corresponding to the position information of the electronic pen 2. Thereby, in the virtual sticky note moving mode in which the procedure of step SS130 is switched, an operation can be performed to move the existing virtual sticky note paper.

  In the present embodiment, in particular, the procedure of step SS165 creates a new virtual sticky note at the coordinate position in the display area corresponding to the position information of the electronic pen 2, and uses the electronic pen 2 on the new virtual sticky note. The stroke data corresponding to the description on the memo paper 11 is input and displayed. Thus, in the virtual sticky note input creation mode in which the procedure of step SS130 is switched, a new virtual sticky note can be created and stroke data can be input.

  In the above embodiment, the frequency f of the magnetic field generated from the coil 44 of the electronic pen 2 is switched only by turning the tip switch 42 on and off, but the present invention is not limited to this. In addition, as shown in FIG. 14 corresponding to FIG. 3, a changeover switch that can switch the frequency f of the magnetic field to the position of the fingertip when the user holds the electronic pen 2 in the same manner as the tip switch 42. 48 may be provided. Accordingly, the user can cause the separation frequency f2 to be transmitted by operating the changeover switch 48 while the electronic pen 2 is in the pen-up state, and cause the memo pad body 10 to detect the pen-down state in a pseudo manner. be able to.

  As described above, since the electronic pen 2 includes the pen tip 2a, the content written by the user can be written on the memo paper 11, while the electronic switch 2 is pen-downed by the changeover switch 48 even when the electronic pen 2 is in the pen-up state. A pseudo magnetic field can be output in a manner corresponding to the state. Thereby, the virtual sticky note paper can be moved by switching to the virtual sticky note moving mode while the electronic pen 2 is in the pen-up state, and the contact of the pen tip 2a with the memo paper 11 at the time of the change and the description of the locus thereof Can be avoided.

  Further, in the virtual sticky note movement mode, as shown in FIG. 15A, the user moves the existing virtual sticky note (highlighted in the drawing) 307 to the position of the movement destination. If other existing virtual sticky notes 308 exist, they can be automatically rearranged so that they do not overlap with each other so that the display of the other existing virtual sticky notes 308 can be avoided. Good. As a specific method, at least one of the existing virtual sticky note 307 to be moved and the other existing virtual sticky note 308 is moved to a position that does not overlap with each other on a line passing through the center point. For example, only the other existing virtual sticky note 308 may be moved as shown in FIG. 15 (b), or only the existing virtual sticky note 307 to be moved may be moved as shown in FIG. 15 (c). The virtual sticky note sheets 307 and 308 may be moved as shown in FIG. In this case, the control procedure processed in this way corresponds to the duplication avoiding means described in each claim.

  By moving and rearranging in this way, natural movement is possible at a relatively short distance compared to the original arrangement position by the user. Note that this processing can also be applied to the case where another existing virtual sticky note exists at the creation position when a new virtual sticky note is created in the virtual sticky note input creation mode.

  Further, in the above embodiment, when switching from the virtual sticky note input creation mode to the cursor movement mode, the switching is triggered when the continuation of the pen-up state of the electronic pen 2 for a predetermined time or more is detected. Not limited to. In addition, the page turning detection unit may be switched when the turning operation of the memo paper 11 is detected.

  Moreover, although the virtual sticky note input display system S of the above embodiment has a so-called stand-alone configuration, the present invention is not limited to this. In addition, as shown in FIG. 16, a plurality of PCs 200 may be connected to one server 250 via a network NW. In this case, the server 250 manages a virtual bulletin board to which all virtual sticky notes are pasted, and a plurality of PCs 200 share and display this virtual bulletin board and perform operations for creating and moving virtual sticky notes respectively. Do. According to the virtual sticky note input / display system S2 configured in this manner, a plurality of users far away from each other attach virtual sticky notes describing their ideas on a shared virtual bulletin board, and are based on a common theme. It can be used for study work, so-called brainstorming.

  In the above embodiment, the position information of the electronic pen 2 constituting the stroke data is detected between the coil 44 on the electronic pen 2 side and the sense coils X1 to Xm and Y1 to Yn on the coordinate detection device 3 side. However, the present invention is not limited to this. In addition, a passive magnetic coupling method, an ultrasonic method, or a dot or pattern pre-printed on the memo paper 11 as a writing instrument is imaged with a camera equipped with the electronic pen 2 and the movement of the point or pattern is detected. For example, the position information of the electronic pen 2 may be detected by a method or the like (detailed description of each method is omitted).

  Also in these other systems, the electronic pen 2 and the memo paper 11 are detected by detecting the on / off of the tip switch 2a of the electronic pen 2 via a wired cable or wireless communication through which the memo pad device 3 can send and receive information. Can be detected, that is, the pen-up state and the pen-down state.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) When using a writing panel that electronically displays the writing content of the electronic pen In the above embodiment, the memo pad device 3 includes the memo paper 11, and the pen tip 2a of the electronic pen 2 is actually the writing surface of the memo paper 11. However, the present invention is not limited to this. In addition, a writing panel that electronically displays the writing contents of the electronic pen may be used. In the following, the same parts as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  As shown in FIG. 17, the sticky note input / display system S <b> 3 of the present modification includes a writing panel 21 and a PC 200 that are connected so as to be able to send and receive information to each other. The PC 200 is equivalent to that of the above embodiment. As shown in FIGS. 18A and 18B, the writing panel 21 includes an electronic pen 2 </ b> A that is an electronic writing instrument, and a panel device 23. The electronic pen 2A in this modification does not include the pen tip 2a, and is otherwise equivalent to that of the above embodiment. The panel device 23 includes a liquid crystal panel 24 and a panel body 25 that is arranged so as to overlap the back side of the liquid crystal panel 24 and is integrally fixed. The liquid crystal panel 24, which is both a writing instrument and a drawing display means, is configured to be able to pass through a magnetic field as a whole, and its display area is formed to be approximately the same size as the panel body 25. The panel body 25 has substantially the same configuration as the memo pad body 10 of the above-described embodiment, and a coil sheet 100A having a size substantially the same as that of the panel body 25 is provided therein.

  Although the functional configuration of the panel body 25 is not particularly shown in detail, for example, the liquid crystal panel 24 and the erasure switch 26 are provided in the microcomputer 80 in place of the page turning detection unit 71 in FIG. Connected. The erasure switch 26 is provided on the surface edge of the panel body 25, and is a switch for the user to input an instruction to erase all the display on the liquid crystal panel 24.

  Also with the panel main body 25 having such a configuration, it is possible to detect the contact state and position information of the electronic pen 2A. Further, the panel body 25 is arranged such that the coordinate position of the liquid crystal panel 24 corresponding to the position information of the electronic pen 2A, that is, the electronic pen 2A is on the surface of the liquid crystal panel 24 while the electronic pen 2A is in the pen-down state. It is possible to display a locus by drawing a point at a position in contact with the top. Thereby, the stroke data can be electronically displayed on the liquid crystal panel 24 in the same manner as the pen tip 2a of the electronic pen 2 is actually written on the writing surface of the memo paper 11 in the above embodiment.

  In this modification using the writing panel 21, the operations of the cursor movement mode and the virtual sticky note input creation mode are the same as those in the above embodiment, but the virtual sticky note movement mode is different. Hereinafter, the procedure of the virtual sticky note movement mode in this modification will be described with reference to FIG.

  First, in the cursor movement mode, a virtual sticky note that moves the existing virtual sticky note 304 by pen-downing the electronic pen 2A with the cursor 310 in the display area of the display unit 201 superimposed on the existing virtual sticky note 304. Switch to paper movement mode. In this modification, the pen-down state is maintained without pen-up of the electronic pen 2A thereafter (see FIG. 19A).

  Next, as shown in FIG. 19B, the electronic pen 2A is moved along the surface of the liquid crystal panel 24 while maintaining the pen-down state, so that the electronic pen 2A moves on the display screen in accordance with the movement of the electronic pen 2A. The cursor 310 and the existing virtual sticky note 304 to be moved are moved and displayed together. At this time, although the electronic pen 2A is in the pen-down state, it is not necessary to display the locus of movement of the electronic pen 2A by stopping the writing display function itself of the liquid crystal panel 24.

  Then, when the existing virtual sticky note 304 to be moved is moved to an arbitrary destination, the user simply lifts the electronic pen 2A as shown in FIG. The virtual sticky note moving mode can be ended.

  After that, returning to the cursor movement mode and moving the electronic pen 2A along the surface of the liquid crystal panel 24 while maintaining the pen-up state, only the cursor 310 on the display screen can be moved and displayed (see FIG. 19 (d)).

  In order to realize the functions as described above, the contents of the control processing performed by each of the CPU 80a of the panel body 25 and the CPU (not shown) of the PC 200 in this modification will be described in order with reference to FIGS. explain.

  The flow of FIG. 20 executed by the CPU 80a of the panel body 25 is roughly the same as the flow of FIG. 12 of the above embodiment, and only the differences will be described below. In FIG. 20, after the execution of each procedure of step SS20, step SS35, and step SS40, the process proceeds to step SS45 without returning to step SS5.

  In step SS45, the CPU 80a determines whether or not the sticky note movement mode information indicating that the PC 200 has switched to the virtual sticky note movement mode has been received. If the sticky note movement mode information is received, the determination is satisfied, and the routine goes to Step SS50.

  In step SS50, the CPU 80a stops the writing display function of the liquid crystal panel 24, and avoids displaying the movement path of the electronic pen 2A accompanying the movement operation of the existing virtual sticky note paper. And it returns to step SS5 and repeats the same procedure.

  On the other hand, if it is determined in step SS45 that the sticky note transfer mode information is not received, the determination is not satisfied and the process proceeds to step SS55.

  In step SS55, the CPU 80a determines whether or not the sticky note input creation mode information indicating that the PC 200 has switched to the virtual sticky note input creation mode has been received. If the sticky note input creation mode information is received, the determination is satisfied, and the routine goes to Step SS60.

  In step SS60, the CPU 80a activates the writing display function of the liquid crystal panel 24, and causes the liquid crystal panel 24 to display stroke data input by writing with the electronic pen 2A. And it returns to step SS5 and repeats the same procedure.

  On the other hand, if it is determined in step SS55 that the sticky note input creation mode information has not been received, the determination is not satisfied and the routine returns to step SS5 and the same procedure is repeated.

  Next, the contents of the control process performed by the CPU of the PC 200 in this modification will be described in order with reference to FIG. The flow of FIG. 21 is also substantially the same as the flow of FIG. 13 of the above embodiment, and only the differences will be described below. In FIG. 21, if it is determined in step SS130 that the display content detected in step SS125 is an existing virtual sticky note, the determination is satisfied, and the process proceeds to step SS133.

  In step SS133, the CPU 80a transmits sticky note movement mode information indicating that the mode has been switched to the virtual sticky note movement mode to the panel body 25. As a result, as described in step SS50 above, the panel main body 25 can stop the writing display function of the liquid crystal panel 24, thereby avoiding the display of the movement locus of the electronic pen 2A accompanying the movement operation of the existing virtual sticky note paper. That is, the virtual sticky note moving mode process can be executed while maintaining the pen-down state detected in step SS120. For this reason, in this modification, the procedure of step SS135 shown in FIG. 13 of the above embodiment is omitted, and the process proceeds to step SS140.

  In step SS140, the CPU 80a receives the pen position information from the panel main body 25, and performs processing in the virtual sticky note movement mode based on this relative change in the same manner as in the above embodiment. Further, in this modified example, while the virtual sticky note moving mode is continued, the pen-down state does not directly shift to the no-pen state, so the procedure of step SS145 shown in FIG. 13 of the above embodiment is also omitted. Then, the process proceeds to step SS150A.

  In step SS150A, the CPU determines whether pen-up information has been received from panel body 25 or not. If pen-up information has not been received from the panel body 25, the determination is not satisfied and the routine returns to step SS140 and the same procedure is repeated. While repeating the above steps SS140 to SS150, the user can move the cursor 310 and the virtual sticky note to be moved to any position on the display area of the display unit 201 of the PC 200.

  On the other hand, if it is determined in step SS150A that the pen up operation is received from the panel body 25 by the user performing a pen up operation, the process proceeds to step SS155.

  On the other hand, if it is determined in step SS130 that the display content detected in step SS125 is other than an existing virtual sticky note, the determination is not satisfied, and the process proceeds to step SS158.

  In step SS158, the CPU 80a transmits to the panel body 25 sticky note input creation mode information indicating that the mode has been switched to the virtual sticky note input creation mode. Then, the process proceeds to step SS160.

  As described above, when the processing on the PC 200 side is switched to either the virtual sticky note moving mode or the virtual sticky note input creation mode, the corresponding information is transmitted from the PC 200 to the panel main body 25, and the panel main body 25 The writing display function of the liquid crystal panel 24 can be activated only during the virtual sticky note input creation mode.

  As described above, in the virtual sticky note input display system S3 of the present modification, the liquid crystal panel 24 can temporarily display the contents of writing by the user on the liquid crystal panel 24. Further, by causing the liquid crystal panel 24 to display only when the procedure of step SS130 is switched to the virtual sticky note input creation mode, only the contents written by the user are displayed on the liquid crystal panel 24, and the virtual sticky note is moved. In the mode (virtual sticky note operation mode), when the electronic pen 2A moves in the pen-down state and moves the virtual sticky note, display of the movement locus can be avoided.

  Note that, when switching from the virtual sticky note input creation mode to the cursor movement mode, the switching may be triggered when the operation of the erasure switch 26 is detected.

(2) When switching to the virtual sticky note enlargement / reduction mode in the virtual sticky note operation mode In the embodiment and the first modification, the virtual sticky note operation mode is only the virtual sticky note movement mode. It is not limited to this. In addition to the virtual sticky note movement mode, the virtual sticky note operation mode may be selectively switched and executed, for example, including a virtual sticky note enlargement / reduction mode for enlarging or reducing the size of the virtual sticky note. Good. Note that the hardware configuration of this modification is equivalent to that of the first modification, and the same reference numerals are given to the same parts, and the description thereof is omitted as appropriate.

  In this modification, the operations of the cursor movement mode, the virtual sticky note input creation mode, and the virtual sticky note movement mode are the same as in the first modification, and a virtual sticky note enlargement / reduction mode is newly added. Hereinafter, the procedure of the virtual sticky note enlargement / reduction mode in this modification will be described with reference to FIG.

  First, in the cursor movement mode, by pen-downing the electronic pen 2A with the cursor 310 in the display area of the display unit 201 superimposed on the existing virtual sticky note 304, first, the existing virtual sticky note 304 is placed in order. Switch to virtual sticky note movement mode to move Also in this modification, the pen-down state is maintained without penning up the electronic pen 2A thereafter. By moving the electronic pen 2A immediately at this time, the existing virtual sticky note 304 to be moved can be moved as in the first modification (see FIG. 19B).

  However, in the present modification, when the pen-down state is maintained without moving the electronic pen 2A for a predetermined time or more after the pen-down, the virtual sticky note moving mode is automatically switched to the virtual sticky note enlargement / reduction mode (see FIG. 22 (b)). After switching to the virtual sticky note enlargement / reduction mode, the size of the existing virtual sticky note 304 is enlarged and reduced by moving the electronic pen 2A in a predetermined direction while maintaining the pen-down state of the electronic pen 2A. Any of the operations can be selected according to the moving direction, and can be enlarged or reduced at a magnification corresponding to the moving amount (see FIG. 23 described later).

  Then, when the existing virtual sticky note 304 to be enlarged or reduced is enlarged or reduced to a desired size, the user simply lifts the electronic pen 2A and puts it in a pen-up state as shown in FIG. Thus, the virtual sticky note enlargement / reduction mode can be ended.

  After that, returning to the cursor movement mode and moving the electronic pen 2A along the surface of the liquid crystal panel 24 while maintaining the pen-up state, only the cursor 310 on the display screen can be moved and displayed (see FIG. 22 (d)).

  As the setting of the moving direction of the electronic pen 2A for selecting the enlarging operation and the reducing operation described above, for example, as shown in FIG. 23A, the moving amount (change amount) when moved downward from the initial position. ) Enlarges the existing virtual sticky note at a magnification corresponding to (), and when moving it upward, the existing virtual sticky note is reduced at a magnification corresponding to the amount of movement.

  Furthermore, as shown in FIG. 23B, a setting that reflects the movement in the left-right direction may be applied. For example, when the electronic pen 2A is moved in the diagonally downward right direction, the lower side and the right side of the existing virtual sticky note paper are simultaneously moved in the enlargement direction. At this time, the ratio of the vertical component and the horizontal component in the movement direction vector may be similar to the ratio of the lower side enlarged movement amount and the right side enlarged movement amount, respectively.

  The contents of control processing performed by the CPU (not shown in particular) of the PC 200 in this modification for realizing the functions as described above will be described in order with reference to FIGS. The control process performed by the CPU 80a of the panel body 25 is the same as that in FIG.

  The flow of FIG. 24 executed by the CPU of the PC 200 is roughly the same as the flow of FIG. 21 of the first modified example, and only the differences will be described below. In FIG. 24, after the procedure of step SS140 is executed, the process proceeds to step SS141.

  In step SS141, the CPU determines whether or not the existing virtual sticky note paper has been moved by actually detecting the movement of the electronic pen 2A in the procedure of step SS141. If the existing virtual sticky note has not been moved, the determination is not satisfied, and the routine goes to Step SS142.

  In step SS142, the CPU increases the value of the timer counter T by one. Then, the process proceeds to step SS150A.

  On the other hand, if the existing virtual sticky note is moved in the determination in step SS141, the determination is satisfied, and the process proceeds to step SS143.

  In step SS143, the CPU resets the value of the timer counter T to zero. Then, the process proceeds to step SS150A.

  In step SS150A, the CPU determines whether pen-up information has been received from panel body 25 or not. If pen-up information has not been received from the panel body 25, the determination is not satisfied, and the routine goes to Step SS153.

  In step SS153, the CPU determines whether or not the value of the timer counter T is greater than a predetermined value T2. In other words, it is determined whether or not the pen-down state and the movement stop state have continued for a long time that allows the user to determine that he / she is willing to switch from the virtual sticky note movement mode to the virtual sticky note enlargement / reduction mode. If the value of the timer counter T is equal to or less than the predetermined value T2, the determination is not satisfied and the routine returns to step SS140 and the same procedure is repeated. While repeating the above steps SS 140 to SS 153, the user can move the cursor 310 and the virtual sticky note to be moved to an arbitrary position on the display area of the display unit 201 of the PC 200.

  On the other hand, if it is determined in step SS153 that the value of the timer counter T is greater than the predetermined value T2, the determination is satisfied, and the process proceeds to step SS200. Accordingly, the virtual sticky note moving mode is switched to the virtual sticky note enlargement / reduction mode in the virtual sticky note operation mode.

  In step SS200, the CPU performs a virtual sticky note enlargement / reduction process for enlarging or reducing the size of the existing virtual sticky note paper (see FIG. 25 described later). Then, after executing the virtual sticky note enlargement / reduction process, the process returns to step SS105 and the same procedure is repeated. At this time, the virtual sticky note enlargement / reduction mode is switched to the cursor movement mode again.

  On the other hand, if the pen-up information is received from the panel body 25 in the determination in step SS150A, the determination is satisfied, and the process proceeds to step SS155.

  Next, details of the control process performed in the virtual sticky note enlargement / reduction process in step SS200 will be described in order with reference to FIG.

  First, in step SS205, the CPU receives pen position information from the panel body 25, and performs an enlarged display or a reduced display of a virtual sticky note in response to a relative change in the pen position information. Note that the existing virtual sticky note to be enlarged / reduced is detected from the cursor position in step SS125, and even in this case, the existing virtual sticky note is highlighted. Further, the relative change in the pen position information, that is, the correspondence relationship between the movement direction and movement amount of the electronic pen 2A, the enlargement / reduction direction, and the magnification is based on the setting illustrated in FIG. The procedure of step SS205 corresponds to specific processing in the virtual sticky note enlargement / reduction mode.

  Then, the process proceeds to step SS210, and the CPU determines whether pen-up information has been received from the panel body 25. If pen-up information has not been received from the panel body 25, the determination is not satisfied and the routine returns to step SS205 and the same procedure is repeated. While repeating the above steps SS205 to SS210, the user can enlarge or reduce the virtual sticky note to be enlarged or reduced on the display area of the display unit 201 of the PC 200 to an arbitrary size.

  On the other hand, if it is determined in step SS210 that the user has performed pen-up operation and pen-up information is received from the panel body 25, the process proceeds to step SS215.

  In step SS215, the CPU returns the existing virtual sticky note paper that has been the target of enlargement / reduction from the above-described highlight display to the display in the normal mode, and displays it in a fixed size at that time. Then, this flow ends.

  In the above, steps SS130 and SS153 in the flow of FIG. 24 correspond to the mode switching means, and steps SS133 to SS155 and SS200 correspond to the display object operation mode, of which steps SS133 to SS155 The procedure corresponds to the display object movement mode, and the virtual sticky note enlargement / reduction processing in step SS200 corresponds to the display object enlargement / reduction mode. Further, the procedure of step SS205 in the flow of FIG. 25 corresponds to the display object enlargement / reduction mode execution means.

  As described above, in the virtual sticky note input / display system S of this modification, the procedure of step SS205 enlarges the size of the existing virtual sticky note in accordance with the amount of change in the pen position information of the electronic pen 2A. Or reduce it. Thereby, in the virtual sticky note enlargement / reduction mode switched in the procedure of step SS153, an operation can be performed to enlarge or reduce the existing virtual sticky note paper.

  In the second modified example, only two virtual sticky note movement modes and virtual sticky note enlargement / reduction modes are shown as specific execution modes included in the virtual sticky note operation mode. Various operation modes such as a mode and a mode for changing the display color may be prepared and selectively switched for execution.

  In addition, in the above, the arrow shown in each figure of FIG. 4 etc. shows an example of the flow of a signal, and does not limit the flow direction of a signal.

  Further, the flowcharts shown in FIGS. 12, 13, 20, 21 and the like do not limit the present invention to the procedure shown in the above-described flow, and the procedure can be added without departing from the spirit and technical idea of the invention. You may delete or change the order.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
