  Next, the operation of the car navigation system 1 having the above configuration will be described. Below, the operation | movement which reads the several point of the map book 5 with the electronic pen 4 and displays the path | route around the several point extracted based on the reading on the liquid crystal device 66 of the navigation main body 2 is demonstrated.

  First, the user reads the map book 5 with the electronic pen 4. As shown in FIG. 2, a reset mark 22 and a determination mark 23 are printed on the page of the map book 5 together with the map image 21. For example, as shown by a dotted line in FIG. 2, the user checks the reset mark 22 with the pen tip (tip of the ball-point pen shaft 31) of the electronic pen 4 and a plurality of points (for example, in FIG. 2) in the map image 21. In (1), (2) and (3)), 1 with circles, 2 with circles and 3 with circles as handwritten characters are written, and the decision mark 23 is checked.

  The read data generation unit 41 of the electronic pen 4 starts the infrared irradiation process when a writing pressure value equal to or greater than a predetermined threshold is input from the writing pressure sensor 32. When the pen pressure value from the pen pressure sensor 32 is equal to or lower than a predetermined threshold, the read data generation unit 41 of the electronic pen 4 ends the infrared irradiation process. The read data generation unit 41 executes an infrared irradiation process when each mark is checked and when each point is read.

  In the infrared irradiation process, the read data generation unit 41 causes the infrared LED 33 to emit infrared light. Infrared rays output from the infrared LED 33 are reflected by a portion of the paper where the pen tip hits. The coordinate pattern 13 is overlaid and printed on various marks such as the reset mark 22 and the map image 21. The coordinate pattern 13 absorbs infrared rays by the arrangement of the plurality of dots 12. The CMOS sensor 34 receives infrared rays reflected by the paper without being absorbed by the dots 12. The CMOS sensor 34 supplies infrared intensity distribution data to a read data generation unit 41 implemented in the microcomputer 38.

  When infrared intensity distribution data is supplied from the CMOS sensor 34, the read data generation unit 41 analyzes the image. First, the read data generation unit 41 includes an absorption pattern that matches the reset print pattern data 47 stored in the nonvolatile memory 37 in the infrared absorption pattern in the read image, or a decision print stored in the nonvolatile memory 37. It is determined whether or not an absorption pattern that matches the pattern data 48 is included.

  When the absorption pattern that matches the reset print pattern data 47 is included in the infrared absorption pattern in the read image, the read data generation unit 41 resets the nonvolatile memory 37 and starts the process of adding the read data 46. . The read data generation unit 41 erases past read data 46 stored in the nonvolatile memory 37.

  When the absorption pattern that matches the determined print pattern data 48 is included in the infrared absorption pattern in the read image, the read data generation unit 41 ends the process of adding the read data 46.

  When the absorption pattern of infrared rays in the read image does not include either the absorption pattern that matches the reset print pattern data 47 or the absorption pattern that matches the determined print pattern data 48, the read data generation unit 41 uses the coordinate pattern in the image. 13 is specified. The read data generation unit 41 obtains a coordinate value unique to the coordinate pattern 13 from the identified coordinate pattern 13 by a predetermined algorithm.

  When the coordinate value is obtained from the read image generated by the CMOS sensor 34, the read data generation unit 41 acquires time information from the timer 36 and acquires the pen pressure value from the pen pressure sensor 32. The read data generation unit 41 stores the acquired coordinate value, writing pressure value, and time information in the nonvolatile memory 37. The nonvolatile memory 37 adds the three data supplied from the read data generation unit 41 to the read data 46 as one record of the read data 46.

  As described above, the user checks the reset mark 22, and adds 1 with a circle, 2 with a circle, and 3 with a circle at points (1), (2), and (3) in the map image 21. When the writing and the determination mark 23 are checked, read data 46 as shown in FIG. 6 is accumulated and stored in the nonvolatile memory 37, for example. The non-volatile memory 37 is generated by drawing a plurality of records generated by drawing a circle near (1) in the map image 21 and by drawing 1 near (1) in the map image 21. Generated by drawing a circle near (2) in the map image 21 and a plurality of records generated by drawing a circle near (2) in the map image 21 Generated by drawing a circle near (3) in the map image 21 and a plurality of records generated by drawing a circle near (3) in the map image 21 The read data 46 including a plurality of records to be recorded is stored. The non-volatile memory 37 stores read data 46 including six handwriting data.

  When the above reading operation is completed, the user connects the electronic pen 4 and the navigation body 2 with the USB cable 3.

  When the electronic pen 4 and the navigation main body 2 are connected by the USB cable 3, data transmission / reception is performed between the USB I / F 35 of the electronic pen 4 and the USB I / F 68 of the navigation main body 2 by, for example, the USB mass storage class. Is possible. The read data transmitting unit 42 of the electronic pen 4 transmits the read data 46 stored in the nonvolatile memory 37 to the read data receiving unit 133 of the navigation main body 2. The read data 46 transmitted by the read data transmitting unit 42 is transmitted to the read data receiving unit 133 via the USB I / F 35 of the electronic pen 4, the USB cable 3, and the USB I / F 68 of the navigation main body 2. The read data receiving unit 133 stores the received read data 46 in the temporary memory 67. The temporary memory 67 stores the read data 46 received by the read data receiving unit 133 as received read data 90.

  When new unprocessed received read data 90 is stored in the temporary memory 67, the read data processing unit 134 starts processing the unprocessed received read data 90.

  FIG. 10 is a flowchart showing a flow of processing executed by the read data processing unit 134 in FIG. 7 on the unprocessed received read data 90. The read data processing unit 134 first determines whether or not unprocessed received read data 90 is stored in the temporary memory 67 (step ST1).

  When the unprocessed received read data 90 is not stored in the temporary memory 67, the read data processing unit 134 repeatedly executes this determination process (step ST1). The read data processing unit 134 waits for unprocessed received read data 90.

  When the unprocessed received read data 90 is stored in the temporary memory 67, the read data processing unit 134 starts the point extraction registration process. For example, when a command mark for controlling the use of data read by the electronic pen 4 such as a destination setting mark and a landmark acquisition mark is printed on the page of the map book 5, a read data processing unit In step 134, it is determined whether or not the destination setting process is being performed. If the destination setting process is being performed, the point extraction and registration process may be started.

  In the point extraction / registration process, the read data processing unit 134 first reads the record of the first point of the unprocessed received read data 90.

  When a plurality of points on the map book 5 are designated by the electronic pen 4, the user's work of designating a certain point (entering a circle and a number) and then designating the next point is to some extent during the designation of each point. Time intervals occur. The time interval is normally a time interval of about several seconds of 1 second or more.

  In the plurality of records that are read continuously, the read data processing unit 134 does not process until the read time data 53 is separated at a time interval that is more than a predetermined separation time such as 0.5 seconds or 1 second. A plurality of records within the range are read (step ST2). In the read data 46 of FIG. 6, the first point-by-point data composed of the first two handwriting data is read by this reading process.

  When the data for each point is read, the read data processing unit 134 calculates the average value of the coordinates of the plurality of read coordinate data 51 based on all the read records (step ST3). When the handwriting of a circle and the handwriting of 1 overlap, the average value of this coordinate becomes a coordinate value of the approximate center position of the circle.

  After calculating the average value of the coordinates of the plurality of read coordinate data 51, the read data processing unit 134 converts the average value of the coordinates into latitude / longitude data usable by the navigation main body 2 (step ST4). The read data processing unit 134 reads the latitude / longitude data 111 corresponding to the average value of the calculated coordinates from the latitude / longitude conversion table 81, for example.

  When the latitude / longitude data of the point based on the read point-by-point data is obtained, the read data processing unit 134 starts processing for specifying the rank of the point. Note that the read data processing unit 134 may first specify the rank of the point based on the read point-by-point data, and then obtain the latitude and longitude data of the point.

  In the spot order specifying process, the read data processing unit 134 first reproduces the handwriting based on the read point-by-point data (step ST5). In the read record, the value of the read coordinate data 51, the value of the pen pressure level data 52, and the value of the read time data 53 change for each stroke. This change is larger than the change in the value of the reading coordinate data 51, the change in the value of the pen pressure level data 52, and the change in the value of the reading time data 53 in one stroke. The read data processing unit 134 recognizes one handwriting every time a time interval of, for example, about 0.2 seconds or more shorter than the above-described separation time, and reproduces the handwriting based on the read point-by-point data. To do. The read data processing unit 134 reproduces a circle handwriting and one handwriting based on the first point-by-point data in FIG. In addition, you may make it process these (circle and a number) collectively as one handwriting.

  After reproducing one handwriting or a plurality of handwritings in one point-by-point data, the read data processing unit 134 reads the order pattern data 82 in the CD-ROM 6 and specifies the order designated by pattern matching. The read data processing unit 134 determines whether there is matching pattern data 101 in the rank pattern data 82 that matches the reproduced handwriting or matches within a predetermined difference range (step ST6). When the circle handwriting and the one handwriting are reproduced based on the first point-by-point data in FIG. 6, the read data processing unit 134 matches the reproduced handwriting in the rank pattern data 82. It is determined that there is matching pattern data 101 of “(1)” that matches within a predetermined difference range.

  If there is matching pattern data 101 that matches, the read data processing unit 134 reads the rank data 102 associated with the match pattern data 101 in the rank pattern data 82. The read data processing unit 134 stores the read rank data 102 in the temporary memory 67 in association with the previously specified latitude / longitude data 111 (step ST7). For example, the read data processing unit 134 associates the rank data 102 of the rank “1” with the previously specified latitude / longitude data 111 and stores it in the temporary memory 67. The temporary memory 67 stores a record including the latitude / longitude data 111 and the rank data 112 in addition to the extraction point data 91.

  When there is no matching pattern data 101 that matches, the read data processing unit 134 associates the rank data 112 with a predetermined lowest rank, for example, rank 5 and the like with the previously identified latitude / longitude data 111, Save in the temporary memory 67 (step ST8). The temporary memory 67 stores a record including the latitude / longitude data 111 and the rank data 112 in addition to the extraction point data 91.

  When the storage process of the latitude / longitude data 111 and the rank data 112 in step ST7 or step ST8 is completed, the read data processing unit 134 determines whether the process has been completed up to the end of the received read data 90. For example, the read data processing unit 134 determines whether or not the unprocessed read coordinate data 51 remains in the received read data 90. If the unprocessed read coordinate data 51 does not remain in the received read data 90, the read data processing unit 134 ends the process.

  If the unprocessed read coordinate data 51 remains in the received read data 90, the read data processing unit 134 continues the point specifying process. The read data processing unit 134 reads the record of the next point in the unprocessed range in the received read data 90. The read data processing unit 134 calculates the average value of the coordinates of the plurality of read coordinate data 51 based on all the read records, using the read second point-by-point data, and converts the average value to the latitude / longitude data 111. Convert. Further, the read data processing unit 134 reproduces the handwriting of the read second point-by-point data and determines a match with the matching pattern data 10. The read data processing unit 134 associates the latitude / longitude data 111 with the rank data 112 of the rank corresponding to the determination result and stores the data in the temporary memory 67.

  The read data processing unit 134 determines whether unprocessed read coordinate data 51 remains each time the latitude / longitude data 111 and the rank data 112 based on the data for each point are stored in the temporary memory 67. Then, in the case of the read data 46 of FIG. 6, the read data processing unit 134 repeats the above processing three times and ends the processing. As a result, extraction point data 91 having three records of latitude and longitude data 111 is stored in the temporary memory 67 as shown in FIG. Further, in the extraction point data 91, the first rank data 112, the second rank data 112, and the third rank data 112 are associated with the three latitude / longitude data.

  The UI unit 132 of the navigation main body 2 executes predetermined processing when displaying a display screen such as a destination search screen, a route search screen, a route guidance screen, or the like on the liquid crystal device 66.

  FIG. 11 is a flowchart showing a flow of route search processing by the UI unit 132 in FIG. In the route search process, the UI unit 132 first determines whether or not the extraction point data 91 is stored in the temporary memory 67 (step ST11).

  If the extraction point data 91 is not stored in the temporary memory 67, the UI unit 132 executes a point selection process such as a predetermined destination (step ST18). The UI unit 132 displays a landmark or the like stored in the navigation data 71 on the liquid crystal device 66, and sets a landmark selected from the landmark by using the touch panel 65 or the like as a destination or the like. Thereafter, the UI unit 132 executes a route search process described later (step ST15).

  When the extracted point data 91 is stored in the temporary memory 67, the UI unit 132 reads the extracted point data 91 from the temporary memory 67, and corresponds the points of the plurality of read latitude / longitude data 111 to the ranks based on the rank data 112. Then, it is displayed on the liquid crystal device 66 (step ST12). In this display, for example, the UI unit 132 may display a plurality of points in association with the latitude and longitude on a map read from the navigation data 71 or display a list of a plurality of points. . In addition, even if the UI unit 132 displays each point with the same numerical value as the value of the designated rank, the name of the landmark or the name of the node near the latitude / longitude data 111 read from the navigation data 71 is displayed. May be displayed as, for example, “near **”.

  After displaying the points of the plurality of read latitude / longitude data on the liquid crystal device 66, the UI unit 132 waits for an input instruction (step ST13). And the UI part 132 will correct the extraction point data 91 based on the instruction | indication which changes the position and order | rank of several points to display from the touch panel 65 or the key device 64 (step ST14).

  Further, when there is an input indicating that there is no correction from the touch panel 65 or the key device 64, the UI unit 132 starts a route search process (step ST15). In the route search process, the UI unit 132 searches for a route between points for a plurality of points in the extracted point data 91 stored in the temporary memory 67. Specifically, the UI unit 132 uses the current position as a departure point, travels through a plurality of points in the extraction point data 91 in order, and searches for a route to reach the destination. Alternatively, the UI unit 132 searches for a route to a point such as a set destination. In these route searches, the UI unit 132 searches for a route using the node data and link data of the navigation data 71. The UI unit 132 stores the searched route in the HDD 63. As a result, the guide route data 72 is stored in the HDD 63.

  After searching for the guide route, the UI unit 132 displays the searched route on the liquid crystal device 66 (step ST16). The UI unit 132 reads, for example, scaled map data including the entire searched route from the navigation data 71 and causes the liquid crystal device 66 to display a screen in which the route is allocated on the read map.

  FIG. 12 is a diagram illustrating an example of a display screen that displays a guide route searched based on extracted point data 91 that visits three points in order. In FIG. 12, the three points are displayed by a circled number of 1 with a circle, 2 with a circle, and 3 with a circle according to the order of passage designated by the electronic pen 4. The guide route is displayed with a bold line. At this time, when there are a plurality of points with the same route order (numerals), for example, a route around the plurality of points in the same order may be set in the order in which the travel distance becomes shorter.

  After displaying the search route on the liquid crystal device 66, the UI unit 132 starts guidance based on the route, for example, when the automobile starts moving (step ST17). The UI unit 132 displays, for example, a mark indicating the current position generated by the current position data generation unit 131 on the screen of FIG. 12, and when the current position approaches the corner of the guide route, for example, by voice Notify and guide the route. Further, when the UI unit 132 determines that the current position generated by the current position data generation unit 131 has deviated from the guidance route, the UI unit 132 uses the navigation data 71 to search again and guide the guidance route to the next point.

The car navigation system 1 can search and guide a route around a plurality of designated points in a designated order.

  Further, according to this embodiment, the read data processing unit 134 includes a plurality of read coordinate data 51 in the received read data 90 in units of read coordinate data 51 that are separated by a time interval equal to or longer than a predetermined separation time. The data is divided into data for each point and read, and the average value of the coordinates is calculated using a plurality of read coordinate data 51 read.

  When a plurality of points on the map book 5 are designated by the electronic pen 4, a certain time interval is generated between designations for each point in the user's work of designating a next point after designating a certain point. The time interval is normally a time interval of about several seconds of 1 second or more. In addition, this time interval is longer than the time interval of a plurality of reading time data 53 in one locus by the electronic pen 4.

  Therefore, as in this configuration, by dividing the plurality of read coordinate data 51 in the received read data 90 specifying a plurality of points into a plurality of point-by-point data by a time interval equal to or longer than a predetermined separation time, It is possible to determine a time interval generated during designation for each point, and to correctly associate each read coordinate data 51 with a handwriting for designation of each point.

  Further, according to this embodiment, the read data processing unit 134 determines handwriting matching with the matching pattern data 101 of a predetermined handwriting including numbers. Therefore, the read data processing unit 134 can appropriately determine the rank of each point.

  In this embodiment, the read data processing unit 134 designates the lowest rank in the rank data 112 for points where handwriting matching could not be obtained. The UI unit 132 searches for a route based on the ranking. Therefore, if this configuration is adopted, the user does not need to specify the rank for all points. The car navigation system 1 can search for a route around a plurality of points including a point for which the order is not specified according to the specified order.

A plurality of coordinate patterns 13 are printed on substantially the entire surface of FIG. 13 with ink that absorbs infrared rays. In addition, on the ink that absorbs infrared rays, various rectangular marks such as a traffic guide 151 to a plurality of sightseeing spots, a reset mark 22 and a determination mark 23 are printed by ink that transmits infrared rays.

  Then, as indicated by a plurality of dotted line frames 152 in FIG. 13, for example, a coordinate frame that overlaps the print area of each point in the traffic guidance is registered in the latitude / longitude conversion table 81 in association with the latitude / longitude data 111 of the point. When the electronic pen 4 reads the printing range, the read data processing unit 134 of the car navigation system 1 can generate the latitude / longitude data 111 of the point read by the electronic pen 4.

  In the above-described embodiment, circled numbers are registered in the rank pattern data 82 as the handwriting matching pattern data 101 used for matching determination in order to specify the order of passage of each point. In addition to this, the handwriting matching pattern data 101 may be, for example, a simple number or a number with an underline. The handwriting matching pattern data 101 may be characters and symbols other than numerals, for example, characters such as S indicating a start point and G indicating a goal point.

The read data processing unit 134 can accurately specify the coordinates of a desired point designated by the user with a check mark without being affected by the handwriting for order designation.

  The read data processing unit 134 averages the read coordinate data 51 other than the read coordinate data 51 used for matching with the matching pattern data 101 of a predetermined handwriting, so that the user can check a desired point, for example, In addition, a handwriting that matches the matching pattern data 101 of a predetermined handwriting can be entered in the vicinity for order designation. The read data processing unit 134 can accurately specify the coordinates of a desired point designated by the user using a check mark without being affected by the writing order of handwriting for order designation.

  Further, the read data processing unit 134 does not calculate the average value of the plurality of read coordinate data 51, but specifies other feature points such as a check mark turning point as a representative value of the coordinates, Latitude / longitude data corresponding to the representative value may be obtained.

  In the above embodiment, when there is no matching pattern data 101 that matches the handwriting, the read data processing unit 134 designates the lowest rank as the rank of the spot. In addition, for example, when there is no matching pattern data 101 that matches the handwriting, the read data processing unit 134 may designate a predetermined order such as the highest order.
