Description

[Technical field]

[0001] The present invention relates to a wearable handwritten information acquisition device that is attached to a writing instrument and acquires handwritten information written by the writing instrument. [Background technology]

[0002] Traditionally, based on the results of tests given at schools, cram schools, and other educational institutions, the correct answers for each question given by each respondent are tallied and the respondent's level of understanding and the difficulty level of each question are analyzed.

[0003] For example, in elementary and junior high schools, where the exam format involves teachers (graders) marking each question with a true or false mark in red pen on answer sheets submitted by students (answerers) and returning them to the students, after grading the answers, the graders must manually enter the correct answers for each question by each student into a computer to compile and analyze the data, which is a time-consuming and labor-intensive process.

[0004] Such problems are not limited to grading, but can also occur when converting written information (hereinafter also referred to as written information) into data in various tasks involving actual writing.

[0005] Meanwhile, as shown in Patent Document 1, a wearable handwriting information acquisition device has been proposed that can be attached to a writing instrument and acquires handwriting information by sensing the movement of the writing instrument using an internal acceleration sensor or the like. In such a device, sensing is required so that a state in which writing is being performed (writing state) can be distinguished from a state in which the instrument is simply held but not being written (non-writing state).

[0006] However, the above-mentioned device has a drawback in that it is less reliable in acquiring handwritten information because it determines whether or not the user is writing based on the pressure of the writer's index finger.

[0007] Furthermore, when attached to a writing instrument, the plate-like member has a special shape that protrudes from the side peripheral surface of the writing instrument, which makes it difficult to hold. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Publication No. 8-22367 Summary of the Invention [Problem to be solved by the invention]

[0009] Therefore, the present invention has been made to solve the above-mentioned problems, and its main intended objective is to provide a wearable writing information acquisition device that can reliably detect the writing state, is easy to hold, and can be attached to almost any writing instrument. [Means for solving the problem]

[0010] That is, the wearable writing information acquisition device of the present invention comprises a housing having a writing instrument insertion hole that is open at the front end and closed at the rear end, a fall-out prevention member that restricts the movement of a writing instrument inserted into the writing instrument insertion hole toward the front end to prevent it from falling out, a stopper member that abuts against the writing instrument inserted into the writing instrument insertion hole to restrict further movement of the writing instrument toward the rear end, and a writing state detection sensor that is unresponsive when the writing instrument is in a protruding position where further movement toward the front end is restricted by the fall-out prevention member, and is responsive when the writing instrument is in a pressed-in position where further movement toward the rear end is restricted by the stopper member, and the fall-out prevention member is annular and removably attached to the front end of the housing, and engages with the tapered portion of the writing instrument in the protruding position to restrict further movement of the writing instrument toward the front end. Effect of the Invention

[0011] According to the present invention configured in this way, by actually writing, the writing implement moves to the pressed-in position, and the writing state detection sensor reacts, so that the writing state can be detected reliably. In addition, since the housing can be made cylindrical, even if the wearable handwritten information acquisition device is attached to a writing implement, it is possible to ensure ease of holding and ease of writing.

[0012] Another particularly noteworthy effect is that the anti-slip member is annular and configured to fit into the tapered portion formed on most writing instruments, making it possible to easily attach a variety of writing instruments.

[0013] Furthermore, by removing the fall-off prevention member from the housing, the writing instrument can be removed from the housing, allowing the writing instrument to be replaced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] First Embodiment 1. Overview The wearable writing information acquisition device 100 of this embodiment is attached to a specific writing instrument P to acquire writing information by the writing instrument P, and in this embodiment, is used as one component constituting a test result analysis system. Note that the writing instrument P here is, for example, a red felt-tip pen that is often used for marking, and as shown in Fig. 2 etc., the tip where the pen tip is located is tapered.

[0017] As shown in Figures 1 to 6, this wearable writing information acquisition device 100 comprises a housing 1 having a bottomed writing instrument insertion hole 1a into which the rear side of the writing instrument P is fitted, a fall prevention member 2 that holds the writing instrument P inserted into the writing instrument insertion hole 1a so that it does not fall out toward the tip side, and a push switch 3 which is a writing state detection sensor provided at the bottom of the writing instrument insertion hole 1a.

[0018] 2.Each part configuration (1) Case 1 The housing 1 is long and has an outer diameter dimension set to a size that allows a writer to hold it normally and write with ease.

[0019] (2) Pen insertion hole 1a 5, the writing instrument insertion hole 1a is a bottomed hole that opens at the front end of the housing 1 and extends rearward. The inner diameter of the writing instrument insertion hole 1a is set so that the writing instrument P can be held without any rattling in the radial direction, and the depth is set smaller than the length of the writing instrument P so that the pen tip at the front end of the writing instrument P protrudes.

[0020] (3) Anti-fall-out parts 2 As shown in Figure 3 etc., the anti-slip member 2 is annular, and is removably attached to the tip of the housing 1 by screwing a male thread provided at the tip of the housing 1 into a female thread provided on the inner surface of the anti-slip member 2.

[0021] The inner diameter dimension of this anti-slip member 2 is set to a dimension between the maximum and minimum diameters of the tapered portion Pa of the writing instrument P, and is configured so that the tapered portion Pa of the writing instrument P inserted into the writing instrument insertion hole 1a gets caught (engages) midway and does not slip out any further toward the tip. In the following description, the position where the writing implement P is caught by the anti-fall-out member 2 and further movement towards the tip is restricted is referred to as the protruding position.

[0022] Furthermore, when the writing instrument P is attached to the housing 1 by this anti-fall-out member 2, the length by which the writing instrument P protrudes from the anti-fall-out member 2 is set to a length that allows a cap provided with the writing instrument P to be attached to the protruding portion, and is configured to prevent the pen tip from drying out when not in use.

[0023] (4) Push switch 3 As shown in FIGS. 5 and 6, the push switch 3 is attached to the bottom of the writing instrument insertion hole 1a. More specifically, this push switch 3 is positioned in a position where it directly or indirectly abuts against the rear end surface of the writing instrument P inserted into the writing instrument insertion hole 1a, and also serves as a stopper member that prevents the writing instrument P from moving rearward beyond the position where the push switch 3 is fully pressed with its rear end surface.

[0024] In the following description, the position where the writing implement P presses the push switch 3 and is restricted from moving further rearward is referred to as the pressed-in position.

[0025] Naturally, this pushed-in position is behind the protruding position, and the writing implement P is configured to be movable back and forth in the longitudinal direction between the protruding position and the pushed-in position, as shown in FIG.

[0026] In addition, the inner diameter of the anti-fall-out member 2 and the mounting position of the push switch 3 are set so that, in the protruding position, when the rear end face of the writing instrument P is separated from the push switch 3 or comes into contact with it but is only slightly pressed, the push switch 3 is in a non-pressed state in which it is unresponsive (OFF state).

[0027] On the other hand, in the pressed position, the rear end surface of the writing implement P presses the push switch 3, and the push switch 3 is set to a pressed state in which the switch is in a reactive state (ON state).

[0028] An ON output signal indicating the reaction state of this push switch 3 is transmitted via wire or wirelessly to an information processing device (not shown) such as a computer (not shown).

[0029] (5) Other structures 1, etc., a second push switch 4 that can be pressed radially is provided at the tip of the housing 1 at a position that can be operated with an index finger or the like while writing. The ON output signal of this second push switch 4, like the push switch 3, is transmitted to an information processing device (not shown) such as a computer (not shown) via wire or wirelessly.

[0030] 3. Usage and Operation Next, a method of using the wearable written information acquisition device 100 having the above configuration will be described. The writer first inserts the writing implement P into the writing implement insertion hole 1a from the rear end, and then attaches the anti-fall-out member 2 to the housing 1 by extending it from the pen tip of the writing implement P.

[0031] As a result, the writing implement P is held in the housing 1 with a part of the tapered portion Pa including the pen tip protruding from the anti-slip member 2, as shown in FIG.

[0032] In this state, when a writer grips the housing 1 and points the pen tip downward to write, the writing implement P moves by gravity to the protruding position shown in FIG.

[0033] Next, when writing is started, the writing implement P is pushed backward by the writing pressure and moves to the pushed-in position shown in the figure, whereby the push switch 3 is pushed and turned on.

[0034] Even if the pen tip is pointed upward, the writing implement P moves backwards due to gravity, but the writing implement P cannot reach the pressed-in position by its own weight alone due to the elastic force of the push switch 3, and the push switch 3 cannot be turned on.

[0035] In this way, the wearable handwritten information acquisition device 100 outputs an ON signal in a writing state and does not output an ON signal in a non-writing state. That is, the wearable handwritten information acquisition device 100 in this embodiment outputs information indicating a writing state as handwritten information.

[0036] 4. Test result analysis system As described above, the wearable written information acquisition device 100 in this embodiment is used as one component of a test result analysis system (not shown). Therefore, the outline of the test result analysis system will be briefly described.

[0037] This system is based on the premise that a grader will mark the correct / incorrect answers by hand on the answer sheets submitted by the answerers using the wearable handwritten information acquisition device 100. At this time, the grader is required to mark the questions in the order of the questions, and to mark the correct answers with a circle and the incorrect answers with a check mark (so-called a check mark) on the answer sheets.

[0038] When the grader grades the questions according to the above rules, the wearable written information acquisition device 100 outputs an ON signal while the grader writes a circle or a check mark as written information, and does not output an ON signal otherwise. This ON signal is output intermittently for each question until grading is completed.

[0039] The system's computer receives this written information and records the duration of each ON signal that is sent intermittently for each question, in other words, the time it takes to mark a circle or a check mark. Basically, a circle takes longer to mark than a check mark, so the computer compares these ON signals comprehensively and interprets those that last longer as a circle mark for that question, and those that last shorter as a check mark for that question, and records the correct / incorrect status of each question as data.

[0040] In this way, the system automatically digitizes and stores the handwritten marking results of the graders for each question.

[0041] 5.Effects According to the above configuration, when the writer actually writes, the writing implement P moves to the pressed-in position, and the writing state detection sensor reacts to this, so that the writing state can be detected reliably. On the other hand, when no writing is being performed, the writing implement P cannot move to the pressed-in position due to the elastic restoring force of the push switch 3 unless it is intentionally pressed, so that the non-writing state can also be detected reliably.

[0042] In other words, as long as the writer writes with the writing implement P as usual, the writing state and the non-writing state are reliably detected. Therefore, by using this wearable written information acquisition device 100 in, for example, a test result analysis system, as described above, correct / incorrect information for each question can be reliably detected and automatically converted into data.

[0043] Furthermore, since the housing 1 is cylindrical, even when attached to the writing instrument P, it is easy to hold and easy to write with.

[0044] A particularly noteworthy effect is that the anti-slip member 2 is annular and configured to fit into the tapered portion formed on most writing instruments P, so that various writing instruments P can be attached without difficulty.

[0045] Furthermore, by removing the fall-off prevention member 2 from the housing 1, the writing instrument P can be removed from the housing 1, so that the writing instrument P can be replaced when the ink runs out, for example.

[0046] Furthermore, since the push switch 3 serves as a stopper member and also serves as a biasing body that elastically biases the writing implement P toward the protruding position, this contributes to a simpler structure and lower costs.

[0047] <Other embodiments> In the above embodiment, the writing implement is urged toward the protruding position by the restoring force of the push switch, but a separate elastic body such as a spring may be provided to urge the writing implement toward the protruding position.

[0048] In the above embodiment, the push switch also serves as the stopper member. However, a step or the like that protrudes inwardly in the writing implement insertion hole may be provided and used as the stopper member.

[0049] In the above embodiment, a push switch is used as the writing state detection sensor, but the position of the writing tool in the writing tool insertion hole and the pushed-in position and the protruding position may be detected by a non-contact optical sensor, a magnetic sensor, an ultrasonic sensor, etc. In this case, it is preferable to provide the stopper member and the elastic body separately from the writing state detection sensor.

[0050] This wearable handwritten information acquisition device can be used not only in test result analysis systems, but also in situations where handwritten information needs to be automatically extracted in tasks involving writing. In addition, in the above embodiment, a second push switch is provided in addition to the push switch, so that the respective switches can be made to correspond to the left and right clicks of a mouse, thereby expanding the applicability of the device to various uses as an input device.

[0051] In addition, the present invention can be modified in various ways without departing from the spirit of the invention. [Explanation of symbols]
