Description

  The present invention relates to an input device with slide-type hand-mounted means provided with optical position detecting means.

  Conventionally, as an input device, an optical position detection device (for example, see Patent Document 1) including a plurality of light emitting elements and light receiving elements has been proposed. This is integrally provided on a quadrangular display and formed in a square frame shape. A plurality of light emitting elements are arranged in parallel on one of a pair of L-shaped portions constituting the square frame, and a plurality of light receiving elements facing the light emitting elements are arranged in parallel on the other side. As described above, this rectangular frame-shaped optical position detection device is installed along the periphery of the quadrangular display, and inputs information such as characters by moving a pen or a finger within the rectangular frame. Can be displayed on the display.

  That is, in the square frame, the light is in a grid pattern by the plurality of light emitting elements. When a pen, a finger, or the like is moved within the square frame, the light from the light emitting elements is The light is shielded by a pen, a finger, and the like, and the light-receiving element facing the light-emitting element senses the light, thereby detecting the locus of the pen, the finger, etc. (input information such as characters). The trajectory is output as a signal to the display.

Japanese Patent No. 3682109

  However, since the rectangular frame-shaped optical position detection device is installed along the periphery of the display, the inside of the rectangular frame is widened. Therefore, when trying to input characters or the like into the square frame with the pen or the like, not only the tip of the pen or the like, but also the little finger of the hand holding the pen or the base portion (the little finger ball) and the like are not included in the square frame. In contact with the surface of the display. In this case, since the entire portion in contact with the surface of the display is detected in the square frame, unnecessary information (detection information such as the little finger and its base portion) is displayed on the display. There is a "hands-on" problem. So, if you try to input characters etc. with the pen etc. so that the little finger or its base part does not touch the surface of the display, this character will be disturbed and you can not input properly Problems arise.

  The present invention has been made in view of such circumstances, and when inputting information such as characters with a pen or the like, the little finger of the hand holding the pen or the like or the base portion thereof is not properly detected. An object of the present invention is to provide an input device with slide-type hand-mounting means that allows input.

In order to achieve the above object, an input device with a slide-type hand-mounted means of the present invention includes the following input device (A) and a slide body provided slidably on the frame of the input device, A configuration is adopted in which the slide body is a hand placing means for placing a hand to be used when inputting into the input hollow portion of the input device.
(A) An input device having a frame body in which a space surrounded by a frame is an input hollow portion, and a pair of light emitting means and light receiving means provided on the frame body for projecting and receiving light .

  Here, in the conventional optical position detection device, in order to prevent the “hand touch”, if a hand placing means for placing a hand with a pen or the like is provided at an arbitrary position, the hand placing means Since the lower display is obstructed, the above-mentioned hand placing means becomes an obstacle to input. Therefore, if the hand placing means is slidable, the display can be taken large, but when the hand placing means slides, it will protrude from the display. Therefore, an extra space in consideration of the protrusion is required for installing the optical position detection device. Is required. From these viewpoints, the above-described optical position detection device integrated with the display does not have an idea of providing a hand placing means for placing a hand having a pen or the like.

  The input device with slide type hand placing means of the present invention is provided with hand placing means (sliding body) that is slidable on the frame of the frame-like input device. Therefore, when inputting information such as characters into the input hollow portion of the input device with a pen or a finger, a hand holding the pen or the like can be placed on the hand placing means. Thereby, at the time of the input, it is possible to prevent the little finger of the hand holding the pen or the like or the base portion thereof from entering the hollow portion for input, that is, not to “touch”. As a result, the input device does not cause “hand touch” and can appropriately detect the information such as the input characters (trajectory such as a pen tip or a fingertip). Further, when the input is performed, since the hand placing means can be slid by the movement of the hand placed on the hand placing means (slide body), the input is performed with the hand placed on a sheet or the like. Compared with, hand movement with a pen or the like can be performed lightly, and the input of long sentences is not tired. It should be noted that the input device with sliding hand-mounted means of the present invention is not integrated with a display or the like, but is carried independently even if the slide body slides and protrudes from the input device portion. Since it is free, it is only necessary to move the input device with the slide-type hand-mounted means of the present invention to a place where the protruding portion does not become an obstacle. Unlike the prior art, it is not necessary to take extra space for the slide body to protrude.

  In particular, the slide body includes first and second slide plates stacked in a mutually related state, and the first slide plate is slidable in one direction on the frame of the input device. The second slide plate is slidable in a direction different from the slide direction of the first slide plate, and the second slide plate is used when inputting into the input hollow portion. In this case, the second slide plate (hand-mount plate) is different in two directions as described above. Therefore, when inputting into the input hollow portion, a wide range of movement of a hand holding a pen or the like is facilitated with respect to the input device.

  Furthermore, when the sliding directions of the first and second slide plates are set in directions orthogonal to each other, it is possible to slide in two axial directions (for example, left and right directions and front and rear directions) Slide positioning and input positioning become easier.

  Further, when the slide body is transparent, the input hollow portion can be seen through the slide body, so that it becomes easy to input. For example, when a paper on which a format is written is placed in the input hollow portion, the format can be seen, so that it is easy to input at a predetermined position.

  The light emitting means includes a light emitting element and a plurality of light emitting cores of an optical waveguide connected to the light emitting element, and the light receiving means includes a light receiving element and a light guide connected to the light receiving element. A plurality of light incident cores of the waveguide, and the tip of the light emitting core and the tip of the light incident core face each other while being positioned at the inner edge of the frame body Since the optical waveguide is formed on the frame-like body and the optical waveguide can be formed thin, the input device can be thinned.

  Further, the light emitting means is composed of a plurality of light emitting elements, the light receiving means is composed of a plurality of light receiving elements, and the plurality of light emitting elements and the plurality of light receiving elements are positioned at an inner edge of the frame-shaped body. If the light emitting element and the light receiving element are opposed to each other, the input device is formed to be thick to some extent as a whole and the input device has rigidity and strength. Can do.

  Furthermore, the light emitting means and the light receiving means are composed of modules in which a light emitting element and a light receiving element are stacked one above the other, and the modules are respectively arranged at corners on both sides of one side of the frame-like body. A tape-like retroreflector is disposed on the inner surface of the side excluding the one side in between, and the light projected from the light emitting element of one module is reflected by the retrolight reflector, When light is received by the light receiving element of this one module, the position of the tip of a pen or finger used for input can be specified by triangulation with a small number of parts.

FIG. 1 is a perspective view showing a first embodiment of an input device with sliding hand-mounted means of the present invention. The input device with sliding hand-mounted means of this embodiment is slidable with respect to the input device A on the frame of the rectangular frame-shaped input device A having a rectangular input hollow portion (window portion) S. A slide body B is provided. In this embodiment, the slide body B is composed of first and second slide plates (two slide plates) B ₁ and B ₂ that are overlapped with each other. Among them, the first slide plate B ₁ is slidable on the frame of the input device A in a direction along the pair of parallel frames of the input device A (X direction in the figure). slide plate B ₂ of is freely slide the first surface of the slide plate B ₁ on the first slide plate B ₁ in the sliding direction and the direction perpendicular (Y direction in the drawing). When inputting characters or the like into the input hollow portion S of the input device A with the pen P or a finger, the hand Q holding the pen P or the like is placed on the second slide plate B _2. It has become. As described above, the present invention is characterized in that the slide-type hand placing means (the slide body B) is provided on the frame of the input device A.

  In this way, by providing the slide-type hand placing means (slide body B) on the frame of the input device A, information such as characters can be transferred to the input hollow portion S of the input device A using the pen P or finger. When inputting with the hand etc., the hand Q with the pen P etc. can be put on the said hand mounting means. Thereby, at the time of the input, the little finger of the hand Q holding the pen P or the like or the base portion thereof can be prevented from entering the input hollow portion S, and so-called “hand touch” can be prevented. Can do. As a result, the input device A is not touched, and can appropriately detect information such as input characters (trajectory such as a pen tip or a fingertip). Furthermore, the hand placing means (slide body B) can be slid in accordance with an input with a hand Q having a pen P or the like placed thereon. Therefore, the hand Q holding the pen P or the like can be moved lightly, and the input becomes easy when inputting a long sentence or the like. In particular, in this embodiment, since the slide can be performed in two orthogonal directions (X direction and Y direction in the figure), a wide range of movement is easy. The state shown in FIG. 1 is a state used by a right-handed person. When a left-handed person uses, the arrangement of the input device A and the slide body B may be reversed left and right.

More specifically, the sliding mechanism between the input device A and the first slide plate B ₁ is arranged on the surface of the input device A as shown in FIG. A long groove 81 is formed on the back surface of the _first slide plate B ₁ , and a protrusion 91 slidably engaged with the groove 81 is formed on the back surface of the _first slide plate B ₁ . On the contrary, the projections or the like may be formed on the surface of the input device A, and a groove may be formed on the back surface of the _first slide plate B1. The slide mechanism of the first slide plate B ₁ and the second slide plate B ₂ can also be the same as the above as shown in FIG. 2B [in FIG. 2B, an example. The groove 92 is formed on the surface of the _first slide plate B1, and the protrusion 93 is formed on the back surface of the _second slide plate B2. Incidentally, one of the slide mechanism is also such that the first and second slide plates B _1, B ₂ does not come off easily when fully slid, the end portion such as the groove 81 and 92, (not shown) the stopper Is preferably provided. Further, the slide mechanism is not shown in FIG.

In the slide body B, the size of the upper second slide plate B _{2 is set to} a size that allows the hand Q (see FIG. 1) to be placed thereon, for example, 50 mm × 50 mm to 200 mm. It is set within a range of × 200 mm. The size of the first slide plate B ₁ on the lower side is not less than the size of the _second slide plate B ₂ and a direction perpendicular to the slide direction of the _first slide plate B ₁ (in the drawing). The length in the Y direction) is set to be approximately the same as or longer than the length in the Y direction of the input device A (maximum +50 mm) (same as in the figure). Examples of the material for forming the slide body B include resin, metal, wood, glass, and the like. Among these, transparent resin (polycarbonate resin, acrylic resin, etc.) from the viewpoint of allowing the input hollow portion S to be seen through. ) Or glass. Furthermore, if the thickness of the slide body B is too thin, the slide body B is greatly bent and sensed in the input hollow portion S when the hand Q is placed, and if too thick, the hand Q from the input portion is detected. However, the thickness of the first and second slide plates B ₁ and B ₂ depends on the forming material, but is in the range of, for example, 1 to 20 mm. Set in.

  On the other hand, the input device A has a plan view in FIG. 3A, an enlarged view of the X3-X3 cross section in FIG. 3B, and an enlarged view of the X4-X4 cross section in FIG. As shown in FIG. 3C, a rectangular frame-shaped optical waveguide W having the input hollow portion S, and a control means C having a light emitting element 5 and a light receiving element 6 connected to the optical waveguide W are provided. Yes. The optical waveguide W and the control means C are provided on the surface of the rectangular frame-shaped holding plate (frame body) 7 having the input hollow portion S, and the rectangular frame having the input hollow portion S. It is covered with a protective plate 8. The protective plate 8 has a lid function and is placed so as to cover the optical waveguide W and the control means C, and the portion covering the control means C is raised in a step shape (see FIG. 1). In addition, the height of the input hollow portion S is normally set within a range of 1 to 20 mm. In the case of this embodiment (a configuration using the optical waveguide W), the height is set within a range of 1 to 5 mm. Is also possible.

  As shown in FIGS. 3 (a) and 3 (b), the rectangular frame-shaped optical waveguide W is manufactured by individually producing a strip-shaped optical waveguide portion on each side of the rectangular frame shape, and connecting it to the rectangular frame shape. It has become. In this embodiment, both end edges of each of the strip-shaped optical waveguide portions are formed in stepped portions so as to mesh with end edges of other adjacent optical waveguide portions. And the adjacent optical waveguide part is connected in the state positioned using the step part. Each of the strip-shaped optical waveguide portions includes the under cladding layer 1, the cores 2 a and 2 b formed in a predetermined pattern on the surface of the under cladding layer 1, and the cores 2 a and 2 b covered with the under cladding layer 1. The over clad layer 3 is formed on the surface of the clad layer 1. The under cladding layer 1 is adhered to the surface of the rectangular frame-shaped holding plate 7.

  The optical waveguide W formed in a rectangular frame shape has a light emitting core 2a 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. A plurality of cores 2b for light incidence are formed in parallel on the other surface. The leading ends of the cores 2a and 2b are positioned on the inner edges (inner peripheral edges of the rectangular frame) of the pair of L-shaped portions, and the leading end of the light emitting core 2a and the leading end of the light incident core 2b. Are formed in a state of facing each other. Further, an over clad layer 3 is formed in a rectangular 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 peripheral edge of the rectangular frame 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 circular arc shape in a side cross section. In FIG. 3A, 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. 3A and 3B, the number of cores 2a and 2b is omitted.

  In addition to the light emitting element 5 and the light receiving element 6 described above, the control means C includes a CPU (not shown) for controlling the input device A, as shown in FIGS. An output module (not shown) for outputting information (information on the movement trajectory of the pen tip, etc.) input to the input hollow portion S of the optical waveguide W, and storage means (not shown) such as a memory for storing the information , A battery (not shown) as a power source is also provided and is bulky. The light emitting element 5, the light receiving element 6, the CPU, the output module, the storage means, the battery, and the like are mounted on the circuit board 4 and electrically connected appropriately.

  In such an input device A, the light H from the light emitting element 5 passes through the light emitting core 2a, passes through the lens portion at the tip thereof, and the surface of the lens portion 3a of the over clad layer 3 that covers it. It is emitted from. As a result, the light H is in a grid-like state in the input hollow portion S of the rectangular frame-shaped optical waveguide W. Divergence of the light H running 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. The light H passes through the lens portion 3a of the light-receiving side overclad layer 3, passes through the lens portion at the tip of the light incident core 2b, passes through the light incident core 2b, and passes through the light receiving element 6b. To reach. The light incident on the light incident core 2b is focused and converged by the refractive action of the lens portion 3a of the over clad layer 3 and the lens portion at the tip of the light incident core 2b.

And when inputting information using the above-mentioned input device with a slide type hand placing means, it is input with a finger of a pen P (see FIG. 1) or a hand Q (see FIG. 1). Of these, when inputting with the pen P, for example, the input device with the slide-type hand placing means is placed on paper, the pen P is held in the hand Q (see FIG. 1), and the hand Q is slid. The character P is placed on the second slide plate B ₂ (see FIG. 1) of the body B and exposed to the input hollow portion S where the light H runs in a lattice shape as described above with the pen P. Write figures, marks, etc. As a result, the light H traveling in the lattice shape is shielded by the pen tip of the pen P, and when the light shielding element 6 senses the light shielding, the locus of the pen tip is detected. The locus of the pen tip becomes input information such as characters, figures, and marks, and the locus (input information) is stored as digital data (electronic data) in a storage unit such as the memory. At this time, the hand Q is placed on the second slide plate B ₂ of the slide body B on the input device A (input hollow portion S) as described above. No entry and no detection.

  The input information stored (stored) in the storage means such as the memory can be reproduced (displayed) using a reproduction terminal (personal computer, mobile device, etc.) and further stored in the reproduction terminal. You can also. In this case, the reproduction terminal and the input device A are connected by a connection cable such as a micro USB cable, for example.

  Further, at the time of the input, the input device A may be connected to a personal computer (hereinafter referred to as “personal computer”). In this case, for example, information such as data is displayed on the display of the personal computer, and in this state, information such as characters is input with the pen P in the input hollow portion S of the input device A as described above. . Thereby, the locus of the pen tip is detected by the input device A, and is transmitted as a signal to the personal computer wirelessly or via a connection cable, and can be displayed on the display. Thereby, the information such as the characters input by the input device A is displayed on the display in a state where the information such as the material is superimposed on the information. The displayed contents can be stored in an information storage medium such as a hard disk in the personal computer or an external USB memory.

  On the other hand, when inputting with the finger of the hand Q, the locus of the fingertip is stored as input information in a storage means such as the memory. In this case, paper cannot be written, so paper is not necessary. Similarly to the input with the pen P, the input information saved (stored) in the storage means such as a memory can be reproduced using a personal computer or displayed on the display of the personal computer.

  The personal computer used here has the input hollow of the input device A in order to display characters or the like input in the input hollow portion S of the input device A at the position of the display corresponding to the input position. Software (program) for converting the coordinates of the area in the part S into the coordinates of the screen of the display and displaying characters or the like input by the input device A on the display is incorporated.

[Preparation of slide body B]
Next, an example of a method for producing the slide body B will be described. The first and second slide plates B ₁ and B ₂ of the slide body B are manufactured by a manufacturing method corresponding to the forming material. For example, when a resin is used as the forming material, it is manufactured by injection molding or the like, and when a metal is used, it is manufactured by pressing a metal plate or the like. At this time, the groove 92 and the protrusions 91 and 93 necessary for the slide mechanism are formed (see FIGS. 2A and 2B).

[Production of input device A]
Next, an example of a method for manufacturing the input device A will be described. In this embodiment, the rectangular frame-shaped optical waveguide W is manufactured by individually manufacturing a strip-shaped optical waveguide portion on each side of the rectangular frame shape and connecting it to the rectangular frame shape. 4A to 4C and FIGS. 5A to 5C cited in the description of the method for manufacturing the optical waveguide W illustrate a portion corresponding to FIG. 3B.

  First, a substrate 10 (see FIG. 4A) for forming a strip-shaped optical waveguide portion is prepared. Examples of the material for forming the substrate 10 include metal, resin, glass, quartz, and silicon.

  Next, as shown in FIG. 4A, a strip-like under cladding layer 1 is formed on the surface of the 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. 4B, a light emitting core 2a and a light incident core 2b having the pattern are formed on the surface of the under cladding layer 1 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. Since FIG. 4B is a sectional view on the light incident side, the light emitting core 2a is not shown in FIG. 4B. The same applies to FIGS. 5A to 5C described below.

  On the other hand, as shown in FIG.4 (c), the shaping | molding die 20 which has translucency for over clad layer formation is prepared. The mold 20 is provided with a recess 21 having a mold surface corresponding to the surface shape of the overcladding layer 3 (see FIG. 5B). 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. 5 (a), the cores 2a and 2b patterned on the surface of the under cladding layer 1 are positioned with respect to the recess 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. Thereby, the photosensitive resin 3A is cured, and the over clad layer 3 is formed in which the portion of the over clad layer 3 corresponding to the tip portions of the cores 2a and 2b is formed in the lens portion 3a.

  Next, as shown in FIG. 5 (b) (shown upside down from FIG. 5 (a)), the overcladding layer 3 is removed from the mold 20 (see FIG. 5 (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. 5C, the substrate 10 [see FIG. 4B] is peeled off from the under cladding layer 1 to form a belt-like shape composed of the under cladding layer 1, the cores 2a and 2b, and the over cladding layer 3. An optical waveguide part is obtained.

  On the other hand, as shown in a plan view in FIG. 6A, a circuit board 4 is prepared, and a CPU (not shown) for controlling the light emitting element 5, the light receiving element 6, and the input device A (see FIG. 3). , An output module (not shown) for outputting information input to the input hollow portion S of the optical waveguide W (see FIG. 3), the storage means (not shown), a battery (not shown) and the like are mounted. The control means C is manufactured.

  Next, as shown in a plan view in FIG. 6B, a rectangular frame-shaped holding plate 7 having an input hollow portion S is prepared. Examples of the material for forming the holding plate 7 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 7 is set to about 0.5 mm, for example.

  7 (a) is a plan view, and FIG. 7 (b) is a cross-sectional view (X5-X5 cross-sectional view in FIG. 7 (a)). As shown in FIG. Then, the above-mentioned band-shaped optical waveguide portions are sequentially stuck to produce a rectangular frame-shaped optical waveguide W. At this time, the light emitting element 5 is connected to the light emitting core 2a, and the light receiving element 6 is connected to the light incident core 2b.

Thereafter, as shown in a sectional view in FIG. 8, the portion of the optical waveguide W excluding the lens portion 3 a of the over clad layer 3 and the control means C are covered and protected by a lid-like protective plate 8. Grooves 81 or protrusions necessary for a sliding mechanism with the _first slide plate B ₁ of the slide body B (see FIGS. 2A and 2B) are formed on a predetermined portion of the surface of the protective plate 8. (Not shown in FIG. 8). Examples of the material for forming the protective plate 8 include resin, metal, glass, quartz, and silicon. The thickness of the protective plate 8 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 input device A can be manufactured.

[Manufacture of input devices with slide-type hand-mounted means]
Finally, the first slide plate B ₁ of the slide body (slide-type hand placing means) B is attached to the protection plate 8 of the input device A so as to be slidable using the slide mechanism. In this manner, the input device with slide-type hand placing means shown in FIG. 1 can be manufactured.

In the above embodiment, the sliding directions of the first slide plate B ₁ and the second slide plate B ₂ are two directions (X direction and Y direction in FIG. 1) orthogonal to each other. The two directions may be other, for example, the sliding direction of the second slide plate B ₂ relative to the sliding direction of the _first slide plate B ₁ may be set to an oblique direction.

FIG. 9 is a perspective view showing a second embodiment of the input device with sliding hand-mounted means of the present invention. The input device with slide type hand placing means according to this embodiment is the same as the input device with slide type hand placing means according to the first embodiment described above, but the slide body B has a second slide plate B ₂ (see FIG. 1). Is not provided. That is, the slide body B is composed of one slide plate B ₃ (corresponding to the _first slide plate B ₁ shown in FIG. 1), and slides only in one direction (X direction). . Therefore, a groove 92 (see FIG. 2B) or a projection for a sliding mechanism with the _second slide plate B ₂ is not formed on the surface of the slide body B (slide plate B ₃ ). Then, (see Fig. 1) hand Q with pen P or the like, so as placed on the slide plate B _3. Other parts are the same as those in the first embodiment, and the same reference numerals are given to the same parts.

  In this embodiment, the slide of the slide body B is only in one axial direction (X direction in the figure). However, as in the first embodiment, the input hollow portion S of the input device A has characters and the like.
