Description

  The present invention relates to an electronic pen housing unit capable of housing an electronic pen and an electronic pen system using the same.

  In recent years, electronic pens that digitize written information have been developed, and “Anot pen” developed by Swedish company Anoto is known as a representative one. Anotopen is used with dedicated paper on which a predetermined dot pattern is printed. In addition to the usual ink cartridge for writing characters, etc., the anotopen has a small camera for capturing the dot pattern printed on the dedicated paper and the position coordinates on the dedicated paper from the captured dot pattern. A processor for calculating and a data communication unit for transmitting the calculated position coordinates and the like to an external device are mounted. When the user writes characters on the special paper with an anotopen or puts a check mark on the image designed on the special paper, the small camera captures the dot pattern printed on the special paper as the pen moves. The entry information such as characters and images written by the user is recognized from the continuous position coordinates calculated by the processor. Then, this entry information is transmitted from the Anotopen by the data communication unit to a nearby terminal device such as a personal computer or a mobile phone (for example, see Patent Document 1).

  Patent Document 2 describes a rotation correction processing function that corrects the arrangement of dots on an image caused by the angle of an electronic pen facing the dot pattern. Further, Patent Document 3 discloses a name list sheet that associates a user ID and a pen ID in a collaborative learning system that draws strokes based on entry information transmitted from a plurality of electronic pens. Further, Patent Document 4 discloses a structure of a cradle that receives entry information from an electronic pen and performs charging when the electronic pen is placed.

  Further, the present system 10 includes a name list sheet 7 for associating the user ID with the pen ID of each electronic pen 1. As will be described later, the name sheet 7 is used in a state of being inserted into the name sheet insertion hole 33 of the electronic pen housing unit 3.

[Answer sheet]
The answer sheet (entry form) 5 will be described with reference to FIG. As shown in FIG. 2, a set of a plurality of answer sheets 5 is prepared for each student, and dot patterns (coded patterns) in different coordinate ranges are printed on the same answer sheet 5. Further, squares are printed on the answer sheet 5. The dot pattern is printed with ink containing carbon that absorbs infrared rays, and the squares are printed with ink that does not absorb in the infrared region. The answer sheet 5 may be printed with an entry field, a question, an answer field, and the like.

[Roster paper]
The name list sheet 7 will be described with reference to FIG. A dot pattern (coded pattern) that can be read by the electronic pen 1 is printed on substantially the entire surface of the list sheet 7, and user areas 701 to 704 are defined thereon. The user areas 701 to 704 are user areas for associating the user ID associated with each of the user areas 701 to 704 with the pen ID of the electronic pen 1 that has tapped the user areas 701 to 704. In the user areas 701 to 704, characters “1 Taro”, “2 Jiro”, “3 Saburo”, and 4 Shiro are printed with surroundings.

  The dot pattern printed on the list paper 7 has a dot pattern different from that of the answer sheet 5, and the dot pattern is printed with ink containing carbon that absorbs infrared rays. Further, the frames and characters of the user areas 701 to 704 are printed with ink that does not absorb in the infrared region. A student or the like causes the electronic pen 1 to be accommodated in the electronic pen accommodation unit 3 in a state where the name list sheet 7 is inserted into the electronic pen accommodation unit 3 when the user ID and the pen ID are associated with each other. Thereby, the pen point portion 103 of the electronic pen 1 accommodated in the electronic pen accommodation unit 3 comes into contact with each of the user areas 701 to 704 in accordance with the accommodation location of each electronic pen 1.

As for the correspondence between the answer sheet, the electronic pen and the student (entrant), in this embodiment, as shown in FIG. 4, the student “Taro” answers the answer sheet 5A using the electronic pen 1A, The student “Jiro” answers the answer sheet 5B using the electronic pen 1B, the student “Saburo” answers the answer sheet 5C using the electronic pen 1C, and the student “Shiro” uses the electronic pen 1D. It is assumed that the answer is made on the answer sheet 5D. Further, it is assumed that a lecturer (operator) “Hanako” operates the computer device 2.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) printed on the answer sheet 5 and the name list sheet 7 will be described with reference to FIGS. FIG. 5 is a diagram for explaining the relationship between the dots of the dot pattern printed on the answer sheet 5 and the name list sheet 7 and the values to which the dots are converted. As shown in FIG. 5, each dot of the dot pattern is associated with a predetermined value depending on its position. In other words, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, or right is shifted from the reference position of the grid (intersection of the vertical line and horizontal line). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the paper are determined by the combination of the information thus associated.

  FIG. 6A shows an arrangement of a certain dot pattern. As shown in FIG. 6A, 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern can be obtained no matter where 6 × 6 dots are taken from any part of the paper. Yes. The dot pattern formed by these 36 dots holds the position coordinates (for example, where the dot pattern is on the answer sheet 5). FIG. 6B is a diagram in which each dot shown in FIG. 6A is converted into a corresponding value based on the regularity shown in FIG. 5 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 1 that captures an image of a dot pattern.

[Electronic pen]
Next, the electronic pen 1 will be described with reference to FIG. FIG. 7 is a schematic view showing the structure of the electronic pen 1. 7, the electronic pen 1 includes an ink cartridge 104, an LED 105, a CMOS camera 106, a pressure sensor 107, a processor 108 including a CPU, a memory 109 such as a ROM and a RAM, A communication unit 111 including a real time clock 110, an antenna, and the like, and a battery 112 are provided. The tip of the ink cartridge 104 is a pen tip portion 103, and each student taps the pen tip portion 103 of the electronic pen 1 on the name sheet 7 or abuts on the answer sheet 5 to stroke (handwriting). (Stroke). The ink of the ink cartridge 104 does not include a material that absorbs infrared rays (for example, carbon). Here, contact of the pen tip portion 103 of the electronic pen 1 with the paper is referred to as “pen down”, and removal of the pen tip portion 103 from the contact (contact) state is referred to as “pen up”. . A trajectory written between the pen-down and pen-up of the electronic pen 1 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes.

  The battery 112 is for supplying electric power to each component in the electronic pen 1. For example, the battery 112 is configured to turn on / off the electronic pen 1 itself by attaching and detaching a cap (not shown) of the electronic pen 1. May be. The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 108. The pressure sensor 107 detects the pressure applied through the ink cartridge 104 from the pen tip portion 103 when the student writes characters or marks on the answer sheet 5 with the electronic pen 1 or taps on the name list sheet 7, that is, writing pressure. The value is transmitted to the processor 108.

  The processor 108 switches on / off the switches of the LED 105 and the CMOS camera 106 based on the writing pressure data supplied from the pressure sensor 107. That is, when the student writes characters or the like on the answer sheet 5 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and when the pressure sensor 107 detects a writing pressure higher than a predetermined value, the processor 108 It is determined that the student has started entry, and the LED 105 and the CMOS camera 106 are operated. When the student finishes entering one stroke and releases the electronic pen 1 from the answer sheet 5, the pressure sensor 107 detects pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID, and transmits it to the computer apparatus 2 as entry information.

  The LED 105 and the CMOS camera 106 are attached near the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion of the housing 101 that faces the LED 105 and the CMOS camera 106. The LED 105 illuminates infrared light toward the vicinity of the pen tip portion 103 on the answer sheet 5 and the list sheet 7. The area is slightly shifted from the position where the pen tip portion 103 contacts the answer sheet 5 and the name list sheet 7. The CMOS camera 106 is provided with an infrared transmission filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 captures a dot pattern in an area illuminated by the LED 105, and the image data of the dot pattern is captured. This is supplied to the processor 108. Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 105 are absorbed by the carbon contained in the dots. Therefore, the dot portion has a relatively small amount of infrared reflection, and the portion other than the dot has a relatively large amount of infrared reflection. By photographing with the CMOS camera 106, a threshold value is provided based on the difference in the amount of reflected infrared light, so that a dot region containing carbon can be distinguished from other regions. Therefore, even when an entry column or the like is printed on the answer sheet 5, the printed ink does not have an absorptivity in the infrared region, and thus the processor 108 can recognize the dot pattern. Note that the shooting area by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 6A, and the shooting by the CMOS camera 106 is performed at regular intervals of about 50 to 100 times per second. Is called. Further, the CMOS camera 106 has a sufficient depth of field in order to photograph dots clearly.

  The processor 108 uses the dot pattern of the image data supplied by the CMOS camera 106 while the student's entry is performed, and the X and Y coordinates (hereinafter simply referred to as “X” and “Y” coordinates on the answer sheet 5 of the stroke (handwriting) to be entered by the student. (Also called “coordinate data” or “coordinate information”) is continuously calculated. That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 6A supplied by the CMOS camera 106 into the data array shown in FIG. The data is converted into a Y coordinate bit value, and X and Y coordinate data are calculated from the data array by a predetermined calculation method. The processor 108 has a rotation correction processing function for correcting the arrangement of dots on the image due to the angle of the electronic pen 1 facing the dot pattern, and is used for coordinate calculation. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, and X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. Note that the 6 × 6 dot pattern on the answer sheet 5 and the list sheet 7 does not overlap in the answer sheet 5 and the list sheet 7, so when the student enters characters etc. with the electronic pen 1, it is entered. It can be specified by coordinate calculation by the processor 108 which position of the answer sheet 5 and the name list sheet 7 corresponds to the position.

  The memory 109 stores property information such as pen IDs “pen01” to “pen04”, pen manufacturer numbers, and pen software versions for identifying the electronic pens 1A to 1D. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the computer apparatus 2 as entry information. Transmission to the computer apparatus 2 by the communication unit 111 is performed immediately and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the computer device 2 is stored as stroke information by the computer device 2. In other words, one stroke is made up of one or a plurality of X, Y coordinates (coordinate points), and the computer apparatus 2 can use one or a plurality of pieces constituting one stroke based on the pen-down information and the pen-up information. Recognize coordinate attribute information.

  As described above, each electronic pen 1 </ b> A to 1 </ b> D generates entry information and transmits the entry information to the computer device 2 while the student fills in or contacts the answer sheet 5 and the name list sheet 7. In other words, the electronic pens 1 </ b> A to 1 </ b> D continue to generate entry information and transmit it to the computer device 2 while the student continues to fill in the answer sheet 5 or the like. Then, when the student removes the electronic pen 1 from the answer sheet 5 and the list sheet 7 (pens up), the electronic pen 1 does not detect a writing pressure higher than a predetermined value by the pressure sensor 107. Determines that the person has stopped writing. In this case, the pen-up electronic pen 1 stops the LED 105 and the CMOS camera 106 and stops sending the entry information to the computer device 2.

Is used (the same shall apply hereinafter). This definition is similarly applied to “enlarged display” and “reduced display” described later. That is, “enlarged display” is not used to mean that the actual stroke is enlarged and displayed, but is used to mean that the actual stroke is displayed in a larger size than the thumbnail 201, and “reduced display” is used to reduce the actual stroke. It is not used in the sense of displaying the image, but is used in the meaning of displaying in a size smaller than the enlarged image 200 (the same applies hereinafter).

  On the other hand, when any one of the thumbnails 201 is selected by an operator's mouse operation or the like, the processing unit 24 displays the enlarged image 200 that has already been enlarged and reduces the selected thumbnail 201. Display. That is, the processing unit 24 displays the enlarged images 200 that have already been enlarged and displayed as a list of thumbnails 201 and displays the thumbnails 201 selected by the operator as the enlarged image 200. In other words, the enlarged image 200 that has already been enlarged and the thumbnail 201 selected by the operator are exchanged.

  Further, as shown in FIG. 16, the color is displayed in the user color (classification) information display field 691 of each student. Specifically, the student “Taro” is yellow, the student “Jiro” is yellow, the student “Saburo” is blue, and the student “Shiro” is red. . The operator categorizes the way of thinking (how to solve) the student's answer, assigns a color to each, and selects a desired button among the color classification buttons 71 to 76 for each student. Then, the processing means 24 displays the user color (classification) information display field 691 of each student in the color designated by the operator. In the example shown in FIG. 16, the operator assigns yellow to the idea of an answer using a sequence of numbers, assigns blue to the idea of an answer using a triangular area, and assigns red to the idea of an answer based on the trapezoid area. ing.

In the state where the handle portion 350 is not operated, the distance between the flat plate portion 352 and the bottom surface portion 340 is the same even when the electronic pen 1 is accommodated by the accommodation hole 31 and the pen tip portion accommodation hole 354. The pen tip portion 103 of the pen 1 is kept at a distance that does not contact the bottom surface portion 340 and the name sheet 7 disposed on the bottom surface portion 340.

  FIG. 20 shows a case where pressure is applied to the handle portion 350 in the direction of the arrow “Z1” after the electronic pen 1 is accommodated in the accommodation hole 31 and the name sheet 7 is arranged on the bottom surface portion 340. Sectional drawing of the electronic pen accommodation unit 3 equivalent to is shown.

  As shown in FIG. 20, when the electronic pen 1 is accommodated in each accommodation hole 31 and a pressure is applied to the handle portion 350 in the direction of the arrow “Z1” (that is, the Z-axis negative direction), a flat plate is formed together with the handle portion 350. The part 352 moves in the negative Z-axis direction. As a result, the pen tip portion 103 of each electronic pen 1 comes into contact with the name sheet 7 on the bottom surface portion 340. Thereby, the entry information including the coordinate information and the pen ID corresponding to each user area 701 to 704 of the name sheet 7 in contact with each electronic pen 1 is transmitted from each electronic pen 1 to the computer apparatus 2. Then, the computer apparatus 2 associates the pen ID in the entry information with the user ID of the user definition information based on the received entry information.

[Effects of Second Embodiment]
According to the electronic pen system 10 of the second embodiment, the electronic pen housing unit 3X includes the pen tip position adjustment mechanism 35 that can manually adjust the position of the pen tip portion 103 of the electronic pen 1 housed in the housing hole 31. Prepare. Thereby, the electronic pen system 10 can associate the pen ID of the electronic pen 1 accommodated in the electronic pen accommodation unit 3X with the user ID based on the user's arbitrary timing. Therefore, according to the second embodiment, even when the user mistakes the accommodation hole 31 in which the electronic pen 1 is to be accommodated and accommodates the electronic pen 1 in the other accommodation hole 31, one pen ID is obtained. It is possible to prevent the user IDs from being associated with a plurality of user IDs in a duplicated manner or being associated with a certain pen ID so as not to correspond to any user ID.

[Modification of Second Embodiment]
Next, a modification of the second embodiment will be described. In the second embodiment, Modifications 1 to 5 of the first embodiment and Modification 6 described below can be arbitrarily combined and applied.

(Modification 6)
The configuration of the pen tip position adjustment mechanism 35 suitable for the present invention is not limited to the configuration shown in FIGS. Thus, with reference to FIGS. 21A and 21B, two other specific examples (first configuration example and second configuration example) will be described in detail. As will be described later, in the first configuration example and the second configuration example, the electronic pen 1 accommodated in the accommodation hole 31 is obtained by translating the flat plate portion 352 in the Z-axis direction when the handle portion 350 is operated. All of the pen tip portions 103 are surely brought into contact with the user areas 701 to 704 of the name list sheet 7.

  FIG. 21A is a cross-sectional view of the pen tip adjustment mechanism 35A on the YZ plane passing through the coil spring 353 in the first configuration example. As shown in FIG. 21A, the pen tip position adjusting mechanism 35A is provided with a guide portion 355 that is fixed to the bottom surface portion 340 and extends in the Z-axis direction. The guide portion 355 is a cylindrical member that is provided for each coil spring 353, passes through the center of the spiral formed by the coil spring 353, and further passes through the hole 355 of the flat plate portion 352A that exists in the extending direction of the coil spring 353.

  According to the first configuration example, when the handle portion 350 is operated so as to move in the negative Z-axis direction, the flat plate portion 352 moves in parallel along the guide portion 355. Therefore, the pen tip position adjusting mechanism 35A of the first configuration example prevents the flat plate portion 352 from being tilted when the handle portion 350 is operated, and ensures that all the pen tip portions 103 of the electronic pen 1 housed in the housing hole 31 are secured. Can be brought into contact with the user areas 701 to 704 of the name sheet 7.

  FIG. 21B shows a cross-sectional view of the electronic pen housing unit 3Y on the YZ plane passing through the name sheet insertion hole 33 in the second configuration example. As shown in FIG. 21B, in the second configuration example, the pen tip adjustment mechanism 35Y includes a handle portion 350A and a handle portion 350A on the side surface opposite to the side surface of the flat plate 352 to which the handle portion 350 and the connection portion 351 are attached. A connecting portion 351A is further attached. Then, when associating the pen ID of the electronic pen 1 accommodated in the electronic pen accommodation unit 3Y with the user ID, the operator simultaneously pushes down the handle portion 350 and the handle portion 350A in the negative Z-axis direction. By doing in this way, the flat plate part 352 is translated in the negative direction of the Z-axis. Therefore, also according to the second configuration example, the pen tip portions 103 of all the electronic pens 1 accommodated in the electronic pen accommodation unit 3Y can be reliably brought into contact with the name list sheet 7.
