Description

  The present invention relates to a notebook device that can write (memorize) a memo or the like on a notebook sheet and simultaneously save (store) the memo or the like as digital data (electronic data).

  Some notebooks, such as electronic notebooks, digitally process notes, schedules, and the like (see, for example, Patent Document 1). This is provided with a display for displaying a schedule, etc., and a memo or the like can be input to the display using a dedicated pen. That is, the display has a touch sensor (touch panel), and the tip of the dedicated pen is brought into contact with the display, and the dedicated pen is moved, so that the movement trajectory of the tip of the dedicated pen is recorded. For example, the information is input to the display. The data is stored (stored) in the electronic notebook in a state where the information such as the inputted memo is superimposed on the information such as the schedule displayed on the display.

  Also, an optical position detection device including a plurality of light emitting elements and light receiving elements has been proposed as a means for detecting a movement locus of a pen tip, a fingertip, or the like (see, for example, Patent Document 2). This is formed in a square frame shape, and a plurality of light emitting elements are arranged in parallel on one of a pair of L-shaped parts constituting the square frame, and a plurality of light receiving elements facing the light emitting elements are arranged in parallel on the other side. It has become. Then, information such as a memo is input by moving a pen, a finger or the like within the square frame. That is, when a pen, finger, or the like is moved within the square frame, light from the light emitting element is blocked by the pen, finger, etc., and the light receiving element that senses the light shielding is detected by the light receiving element. The locus of the pen or finger (input information such as a memo) is detected. When the locus is output as a signal to the electronic notebook, it can be input as a memo or the like on the display of the electronic notebook.

  However, the electronic notebook itself may be broken or the stored data may be broken due to an impact such as dropping, and in such a case, the problem arises that the stored data cannot be reproduced. In addition, mainly for elderly people, there is a high demand for not only the above-mentioned electronic notebook but also a notebook that writes on paper with a writing instrument.

  When the above optical position detection device is used as an input means, it is a square frame itself. Therefore, a sheet is placed underneath, a part of the sheet is exposed from the inside of the frame, and the exposed sheet part is exposed. A memo etc. can be directly written with a writing instrument, and the memo etc. can be inputted into an electronic notebook. It is also possible to leave a sheet on which the memo is written. However, since the optical position detection device has a plurality of light emitting elements and light receiving elements arranged side by side in a frame shape, the frame body is thick (thickness of about 6 mm or more), and a pen, a finger, or the like in the frame When the input body is moved and input, due to the thickness of the frame body, the hand used for the input is unnaturally positioned and it is difficult to input. In addition, since the light emitting element is thick, the light from the light emitting element travels to a certain high position (about 4 mm) from the bottom surface of the optical position detecting device. The position is detected not at the bottom surface within the frame but at a certain level. In addition, since the pen or finger at the time of input is usually not at right angles to the bottom surface in the frame but is inclined, the detected locus is the locus of the pen tip or finger tip (trajectory at the bottom surface in the frame). Instead, it becomes a locus on the diagonal, and the memo displayed on the display deviates from the display position intended by the input person. For these reasons, in order to properly display the input memo or the like on the display, the input becomes unnatural.

  The present invention has been made in view of such circumstances, and can write a memo or the like on a sheet, and can appropriately digitize and store the memo or the like. Even if it is possible, it is an object to provide a notebook device that can naturally write on the paper.

In order to achieve the above object, a notebook apparatus according to the present invention includes a notebook in which a paper that can be written with a writing instrument is bound, a frame-shaped optical waveguide (A) below that surrounds at least a part of the paper, A storage means for storing the movement locus of the tip of the writing tool as electronic data when writing to the portion of the paper exposed from the frame with the writing tool is adopted.
(A) A plurality of cores for light emission are formed in one portion facing each other in the frame shape, and a plurality of cores for light incidence are formed in the other portion. An optical waveguide in which the distal end portion of the light emitting core is positioned at the inner edge of the frame shape, and the distal end portion of the light emitting core and the distal end portion of the light incident core are opposed to each other.

  The notebook device according to the present invention includes a frame-shaped optical waveguide (A) that surrounds at least a part of a notebook sheet, and a writing tool that writes on the sheet portion exposed from the frame of the optical waveguide with a writing tool. Storage means for storing the movement trajectory of the tip of the tool as electronic data. Therefore, when a memo or the like is written on a portion of the paper exposed from the inside of the optical waveguide frame with a writing tool, the memo or the like can be left on the paper and stored (stored) in the storage means as electronic data. You can also. Even if the paper is damaged, the contents such as a memo written on the paper can be extracted (reproduced) from the storage means using a personal computer or the like. Furthermore, since the optical waveguide can be formed thinly, when writing a memo or the like on the paper, it does not hinder the writing, and the hand holding the writing instrument can be positioned in a natural position. Therefore, writing on the paper can be performed naturally. Since the optical waveguide is thin as described above, the light emitted from the tip of the light emitting core travels slightly higher from the bottom surface (paper surface) in the frame. Even if writing is performed in an oblique state, the detected trajectory is substantially the same as the trajectory at the tip of the writing instrument (such as a memo written on the paper) and can be stored (stored) in the storage means in an appropriate state. . In addition, since the optical waveguide is thin as described above, the storage means can also be formed thin, and fits in the notebook.

  In particular, when the optical waveguide and the storage means are integrally formed as a storage device, and the storage device is detachable from the notebook, if the storage device is removed from the notebook, the notebook may be lost or lost. Even if there is damage, the contents such as a memo written on the notebook paper can be extracted (reproduced) from the storage means of the storage device using a personal computer or the like. Further, if the storage device is removed from the notebook and stored, the notebook can be discarded, and a large space for storing the notebook is not required.

  In addition, when the tip of the light emitting core and the tip of the light incident core are formed in the lens portion, the light emitted from the lens portion of the light emitting core is diffused. The light can be emitted in a properly suppressed state, and the emitted light can be guided into the core in a state of being properly converged in the lens portion of the core for light incidence. As a result, the light transmission efficiency within the frame of the optical waveguide can be improved, and the locus of the writing instrument within the frame can be accurately detected.

  Furthermore, the tip of the overcladding layer is formed in a state where the tip of the core for light emission and the tip of the core for light incidence are covered, and the tip of the overcladding layer is formed in the lens portion. In this case, on the light exit side, the exit light from the lens portion of the over clad layer can be emitted in a state in which the diffusion of light is appropriately suppressed. It is possible to make the light incident on a wide area of the lens portion and to make the light incident on the end face of the core in a focused state. As a result, the light transmission efficiency within the frame of the optical waveguide can be improved, and the locus of the writing instrument within the frame can be accurately detected.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a first embodiment of the notebook device of the present invention. As shown in FIG. 1 (FIG. 1 shows a state in which the notebook 50 is opened), the notebook apparatus according to this embodiment includes a notebook 50 bound with a sheet 51 that can be written with a writing instrument, A rectangular frame-shaped optical waveguide W that surrounds a part of the optical waveguide W, and storage means for storing the movement trajectory of the tip of the writing instrument as electronic data when writing to the portion of the paper 51 exposed from the inside of the optical waveguide W with the writing instrument C. In this embodiment, a strip-shaped storage means C is integrally formed at one end edge of the optical waveguide W, and the storage device A is formed by the optical waveguide W and the storage means C. As described above, the storage device A that stores information such as a memo to be written on the paper 51 as electronic data is provided in the notebook 50 that writes the memo on the paper 51 with a writing tool. It is.

  In this embodiment, the paper 51 of the notebook 50 has a plurality of binding holes 51a formed on one side edge, and a plurality of freely openable / closable ring bodies 52 that pass through the binding holes 51a. It is bound by the binding tool provided. The paper 51 is detachable by opening the ring body 52 of the binding tool. Further, in this embodiment, one side of the rectangular frame-shaped optical waveguide W is attached in a state where it is positioned in the plurality of ring bodies 52 of the binding tool (FIG. 1 shows that the storage device A is attached). The storage device A is detachable from the notebook 50 by opening the ring body 52 of the binding tool. When the storage device A is used, the storage device A is once removed from the ring body 52 of the notebook 50 and then placed on the paper 51 for use. In FIG. 1, reference numeral 53 denotes a cover of the notebook 50.

  The characteristic storage device A will be described in detail.

  As shown in FIG. 2A, the storage device A is integrally formed with the rectangular frame-shaped optical waveguide W having the same thickness on each side and one end edge of the optical waveguide W. And a strip-shaped storage means C. 2B, which is an enlarged cross-sectional view [X1-X1 cross-sectional view of FIG. 2A] of the optical waveguide W in the storage device A, and an enlarged cross-sectional view of the storage means C. As shown in FIG. 2 (c), which is [X2-X2 cross-sectional view of FIG. 2 (a)], in this embodiment, the optical waveguide W and the storage means C have a rectangular frame shape made of stainless steel or the like. While being fixed on the holding | maintenance board 30, those top surfaces are covered with the protection board 40 which consists of polycarbonate etc. The holding plate 30 is for facilitating holding the flatness of the storage device A, and the protection plate 40 is for protecting the storage device A.

  As shown in FIGS. 2A and 2B, the rectangular frame-shaped optical waveguide W includes an under cladding layer 1, cores 2 a and 2 b, and an over cladding layer 3 as follows. That is, the rectangular frame-shaped under cladding layer 1 is formed on the rectangular frame-shaped holding plate 30. Then, a light emitting core 2a is formed in a state of being branched into a plurality of surfaces on one surface of a pair of L-shaped portions constituting the rectangular frame of the under cladding layer 1, and on the other surface, the light incident core The plurality of cores 2b are formed in parallel. The leading ends of the cores 2a and 2b are positioned at the inner edge of the rectangular frame shape, and are formed so that the leading end of the light emitting core 2a and the leading end of the light incident core 2b face each other. . Further, an over clad layer 3 is formed in a square frame shape on the surface of the under clad layer 1 in a state of covering the light emitting core 2a and the light incident core 2b. In this embodiment, the tip portions of the cores 2a and 2b positioned at the inner edge of the rectangular frame shape are formed as convex lens portions having a curved surface having a substantially ½ arc shape in plan view. The tip of the over clad layer 3 that covers the lens part is formed as a convex lens part 3a having a curved surface with a substantially arc-shaped side sectional shape. In FIG. 2A, the cores 2a and 2b are indicated by chain lines, and the thickness of the chain line indicates the thickness of the cores 2a and 2b. In FIGS. 2A and 2B, the number of cores 2a and 2b is omitted.

  The storage means C includes a circuit board and a battery that supplies electricity to the circuit board. As shown in FIGS. 2A and 2C, the circuit board is connected to the light emitting element 5 connected to the end of the light emitting core 2a and the end of the light incident core 2b. A light receiving element 6, an IC for controlling the storage means C, a memory for storing information such as a memo to be written on a portion of the paper 51 exposed from the frame of the optical waveguide W (information on the movement locus of the tip of the writing instrument), A connection module or the like for outputting information such as a memo stored in the memory to a reproduction terminal (personal computer, mobile device, etc.) is mounted on the flexible printed circuit board 7. In FIG. 2C, the battery, IC, memory, connection module, and the like are collectively shown by hatched portions with reference numeral 8.

  And in the memory | storage device A [refer FIG. 2 (a)-(c)] which consists of the said optical waveguide W and the memory | storage means C, the light from the said light emitting element 5 passes the said core 2a for light emission, and the The light is emitted from the surface of the lens portion 3a of the over clad layer 3 that covers the front lens portion. As a result, the light travels in a lattice shape within the frame of the rectangular frame-shaped optical waveguide W. Divergence of the light traveling in the lattice shape is suppressed by the refractive action of the lens portion at the tip of the light emitting core 2a and the lens portion 3a of the over clad layer 3 covering the lens portion. And, in this state, when writing a memo or the like with a writing tool on the portion of the paper 51 (see FIG. 1) exposed from the inside of the optical waveguide W, the light running in the lattice shape is blocked by the tip of the writing tool, By detecting the light shielding by the light receiving element 6, the locus of the tip of the writing instrument (writing information such as a memo) is detected, and the locus is stored in the memory as digital data (electronic data). It has become. That is, at the same time as writing a memo or the like on the portion of the paper 51 exposed from the frame of the optical waveguide W with a writing tool, the information such as the memo can be stored in the memory of the storage means C.

  As described above, in the notebook device, memos and the like can be left on the paper 51 and can be stored (stored) as electronic data in the memory of the storage means C. When the page of the paper 51 is changed and a memo or the like is written and the memo or the like is stored (stored) in the storage means C, the storage device A is once lifted from the paper 51 and the paper of the changed page is stored. In this state, a memo or the like is written on the paper 51 of the page. In this way, even if the page of the paper 51 is changed and a memo is written, the order in which the memory is stored (stored) can be grasped in the memory, so the memo etc. of each page can be stored (stored). Is possible. Furthermore, in this embodiment, since the storage device A and the paper 51 are detachable, both the storage device A and the paper 51 are removed from the notebook 50, and the storage device A is placed on the removed paper 51. It can also be used. The storage device A can be used only for pages that are to be stored (stored).

  Further, the optical waveguide W can be formed thin (thickness is about 1 mm), and even if the holding plate 30 and the protective plate 40 are provided on the front and back surfaces of the optical waveguide W as in this embodiment, the total thickness is increased. Can be formed to be about 3 mm, and the rectangular frame-shaped portion in which the holding plate 30 and the protective plate 40 are combined with the optical waveguide W does not hinder writing, and writing is easy. Since the optical waveguide W is thin as described above, the light emitted from the tip of the light emitting core 2a is slightly from the bottom surface in the frame even when the thickness of the holding plate 30 is taken into consideration. Even if writing is performed with the writing instrument tilted in order to travel at a high position (approximately 0.6 mm), the detected locus is substantially the same as the locus of the tip of the writing instrument (such as a memo written on the paper 51). And stored (stored) in the memory of the storage means C in an appropriate state.

  Information such as a memo stored (stored) in the memory of the storage means C can be reproduced (displayed) using a reproduction terminal (personal computer, mobile device, etc.), and further for the reproduction It can also be stored in the terminal. In this case, the reproduction terminal and the storage means C are connected by a connection cable such as a micro USB cable, for example. Note that storage (storage) in the memory of the storage means C is performed in a versatile file format such as pdf, for example.

  Next, an example of a method for manufacturing the memory device A will be described. In addition, among this description, FIGS. 3-4 quoted in description of the manufacturing method of the optical waveguide W have shown the part corresponded to the X3-X3 cross section of Fig.2 (a).

  First, a rectangular frame-shaped substrate 10 (see FIG. 3A) for forming the optical waveguide W is prepared. Examples of the material for forming the substrate 10 include metal, resin, glass, quartz, and silicon.

  Next, as shown in FIG. 3A, a rectangular frame-shaped under cladding layer 1 having the same shape is formed on the surface of the rectangular frame-shaped substrate 10. The under cladding layer 1 can be formed by photolithography using a photosensitive resin as a forming material. The thickness of the under cladding layer 1 is set within a range of 5 to 50 μm, for example.

  Next, as shown in FIG. 3B, a light emitting core 2a and a light incident core 2b having the above pattern are formed on the surface of the under-cladding layer 1 having a rectangular frame shape by photolithography. As a material for forming the cores 2a and 2b, a photosensitive resin having a refractive index higher than that of the material for forming the under cladding layer 1 and the following over cladding layer 3 (see FIG. 4B) is used.

  Here, as shown in FIG.3 (c), the square frame-shaped shaping | molding die 20 which has translucency for overcladding layer formation is prepared. The mold 20 has a recess 21 having a mold surface corresponding to the surface shape of the overcladding layer 3 (see FIG. 4B). Then, the molding die 20 is placed on a molding stage (not shown) with the concave portion 21 facing up, and the concave portion 21 is filled with a photosensitive resin 3A that is a material for forming the over clad layer 3.

  Next, as shown in FIG. 4A, the cores 2a and 2b patterned on the surface of the under cladding layer 1 are positioned with respect to the concave portion 21 of the mold 20, and in this state, the under cladding layer 1 is pressed against the mold 20, and the cores 2a and 2b are immersed in the photosensitive resin 3A which is a material for forming the over clad layer 3. In this state, the photosensitive resin 3A is irradiated with ultraviolet rays or the like through the mold 20 to expose the photosensitive resin 3A. As a result, the photosensitive resin 3A is cured, and a square frame-shaped over cladding layer 3 having a square frame-shaped inner peripheral edge formed on the lens portion 3a is formed.

  Next, as shown in FIG. 4 (b) (shown upside down from FIG. 4 (a)), the overcladding layer 3 is formed from the mold 20 (see FIG. 4 (a)). Then, the substrate 10, the under clad layer 1 and the cores 2a and 2b are removed from the mold.

  Then, as shown in FIG. 4C, the substrate 10 (see FIG. 4B) is peeled off from the under cladding layer 1, and a rectangular frame comprising the under cladding layer 1, the cores 2a and 2b, and the over cladding layer 3 is formed. A shaped optical waveguide W is obtained.

  Next, as shown in a plan view in FIG. 5A, a flexible printed circuit board 7 is prepared, and an IC (not shown) for controlling the light emitting element 5, the light receiving element 6, and the storage device A (see FIG. 1) is prepared. 1), a memory (not shown) for storing information such as a memo to be written on a portion of the paper 51 (see FIG. 1) exposed from the frame of the optical waveguide W (see FIG. 1), and the information to the playback terminal A connection module (not shown) for output is mounted and a circuit board is manufactured.

  Here, as shown in a plan view in FIG. 5B, a square frame-shaped holding plate 30 is prepared. The holding plate 30 has a square frame-like side 31 formed thick. Examples of the material for forming the holding plate 30 include metal, resin, glass, quartz, and silicon. Among these, stainless steel is preferable because it is excellent in maintaining flatness. The thickness of the holding plate 30 is set to about 0.5 mm, for example.

  6A is a plan view, and FIG. 6B is a cross-sectional view [X4-X4 cross-sectional view of FIG. 6A], and emits light from the light-emitting element 5 of the circuit board. The light receiving element 6 is connected to the light incident core 2b. In this state, the optical waveguide W is attached to the surface of the holding plate 30, and the circuit board and a battery serving as a power source for the circuit board are fixed. At this time, the optical waveguide W is stuck on the surface of the holding plate 30 except for the band-like portion 31a (see FIG. 5B) on the outer edge side of the thick side 31 and the circuit board. The battery is fixed (the storage means C is fixed) to the strip portion 31a. Reference numeral 8 in FIGS. 6A and 6B collectively represents the IC, memory, connection module, etc. of the circuit board and the battery as described above.

  Thereafter, as shown in a cross-sectional view in FIG. 7, the top surface excluding the lens portion 3 a of the over clad layer 3 and the fixed portion of the circuit board and the battery are covered with a protective plate 40. Examples of the material for forming the protection plate 40 include resin, metal, glass, quartz, and silicon. The thickness of the protective plate 40 is set to, for example, about 0.5 mm if it is made of metal, and about 0.8 mm if it is made of resin.

  In this way, the storage device A can be manufactured. In this storage device A, as described above, the portion of the optical waveguide W should be formed as thin as about 3 mm even if the holding plate 30 and the protective plate 40 on the front and back surfaces thereof are combined. Can do. The portion to which the storage means C composed of the circuit board and the battery is fixed can be formed to a total thickness of about 6 mm when the holding plate 30 and the protective plate 40 on the front and back surfaces thereof are combined.

  In the storage device A, the storage means C is thicker than the optical waveguide W because there is a thick part such as a battery. In the first embodiment, The thick storage means C is formed so as to protrude below the bound paper 51 of the notebook 50. As a result, as shown in FIG. 8 (FIG. 8 shows a side view as viewed from the opened side with the notebook 50 closed), the thick storage means C is an obstacle to the bound paper 51. In other words, the storage property of the storage device A is good. Note that FIG. 8 illustrates a state in which the storage device A is sandwiched between the bound sheets 51.
