Description

  The present invention relates to a laser beam incident position display device that displays an incident position of a laser beam irradiated from a simulated gun.

  Conventionally, various shooting simulation devices (shooting training devices) have been proposed. In particular, since a simulated gun using a laser beam does not use an object such as a plastic bullet, a shooting simulation can be executed safely.

  Here, as an example of a shooting simulation device, one trainer (player) wears a simulation device related to shooting, and a laser beam from a simulated gun held by another trainee (player) enters this light receiver. By doing so, there is one that causes a stimulation current to flow to one trainer (player) and relaxes the muscle (see Prior Art 1, Patent Document 1 below).

  However, in the above-described conventional technique 1, if there are not a plurality of trainees (players), it is impossible to train, and therefore it is not possible to perform a shooting training alone.

Therefore, a screen, an image output means (such as a computer) that outputs an image including the target, an image projection means (projector) that projects an image output from the image output means onto the screen, and a visible light removal filter are used. And a shooting simulator (CCD camera, video camera) that captures image projection planes and acquires image data of beam points generated on the image projection planes. 2).

  According to the present invention, it is possible to reduce the manufacturing cost with a simple configuration, and it is possible to execute shooting training even in a relatively small space.

  Next, a laser beam incident position display device according to a first embodiment of the present invention will be described with reference to the drawings. In this specification, “laser beam” means a laser beam emitted from a simulated gun, and “light” is distinguished from a laser beam, such as sunlight (natural light), a fluorescent lamp, etc. Means light.

  First, as shown in FIG. 1, the principle of laser beam irradiation from the simulated gun 12 will be described. Inside the simulated gun 12, an optical excitation device (not shown) and a pair of mirrors (not shown) are accommodated, energy is injected into the laser medium from outside to excite light, and this light is reciprocated by the mirror. . As a result, light of the same phase is added, and the light is amplified while reciprocating through the mirror, so that a laser beam with reduced energy and directivity is generated. The amplified laser light having the same phase is transmitted as a laser beam through the mirror, emitted from the simulated gun 12 to the outside, and irradiated toward the laser beam incident position display device 10 described later.

  As shown in FIGS. 1 and 2, the laser beam incident position display device 10 includes a frame member 14. A circular hole 16 is formed on one side surface of the frame member 14. The circular hole 16 is provided with a display member (display means) 18 for displaying the incident position of the laser beam. The frame member 14 is provided with a plurality of (two in this embodiment) speakers 20. The shape is not limited to the circular hole 16, and may be other shapes such as a quadrangle and a triangle, and may be an outline such as a human shadow or an animal shadow.

  Further, a plurality of sensors (for example, optical sensors) 32 (laser light detection means, see FIGS. 3 and 4) for detecting a laser beam are provided inside the frame member 14 and on the back side of the display member 18. It has been. The sensors 32 are provided so as to be uniform over the entire shooting area of the display member 18. Specifically, the display member 18 has a plurality of liquid crystal layers 36 (see FIG. 4) arranged on the same plane, and one sensor 32 corresponds to the back side of each liquid crystal layer 36 (one-to-one correspondence). Relationship). Here, the sensor 32 has a property of detecting a laser beam, such as a material whose conductivity is changed by light, a device that generates an electromotive force by light, a device that detects light as heat, and a device that performs photoelectric conversion. is there. For this reason, when a laser beam is incident on any one of the shooting areas of the display member 18, the laser beam is detected by the sensor 32 corresponding to the liquid crystal layer 36 that is the incident position of the laser beam among the plurality of sensors 32.

  Specifically, as a photosensor, photoconductive type (photoconductive cell (element: CdS, PbS, Se)), photovoltaic type (photovoltaic sensor (element: photodiode, Pin photodiode, solar cell), Examples include an internal amplification sensor (element: phototransistor, avalanche photodiode), area sensor (element: photodiode array, CCD image sensor, MOS image sensor), thermoelectric effect type (element: pyroelectric sensor), and the like.

  For example, in a photoconductive type photoconductive element, electrons that freely move around in response to light energy are generated. It has a basic circuit in which the resistance increases when it is not exposed to light and decreases when it is exposed to light. By this change, a laser beam can be detected and a detection signal can be output.

Further, a photovoltaic type photovoltaic element generates a potential difference inside when irradiated with light (photovoltaic effect). In the photodiode, when light is applied to the pn junction, pairs of electrons and holes are generated, which are collected in the n region and the p region, respectively, and a photocurrent is taken out through the electrode. The phototransistor is a transistor having a photodiode structure and an element having an amplification function. In the avalanche photodiode, electrons generated by light are accelerated in the electric field layer of the pn junction to give a large energy, and the electrons are emitted one after another and doubled. This makes it possible to detect weak light. The thermoelectric effect type pyroelectric element detects light energy once changed to heat. Inside this sensor element, positive and negative charges are arranged in a certain direction due to the polarization phenomenon, and show a characteristic as a dielectric. However, this polarization phenomenon changes due to heat, and charges are generated at both ends of the element (focus). Electric effect). Examples of the element exhibiting the pyroelectric effect include single crystal TGS, LiTaO ₃ , and polymer film PVDF.

  As described above, various types of optical sensors have conventionally existed, and all the sensors detect light and use this as a detection signal (electrical signal) for a control device 22 (see FIG. 3) described later. Output.

  As shown in FIG. 3, a control device 22 is provided inside the frame member 14. The control device 22 includes a CPU (or CPU circuit) 24 (position specifying means) that specifies the incident position of the laser beam on the display member 18 based on detection signals from the plurality of sensors 32, and a display member that is the incident position of the laser beam. A power supply circuit 26 (voltage applying means) for applying a predetermined voltage to 18 liquid crystal layers 36 (specifically, electrodes 50, 52, (62, 64), (74, 76) in FIG. 4), and a speaker. A sound source circuit 28 that outputs a predetermined sound effect from 20, a correspondence (table) between a detection signal of the sensor 32 and an incident site (liquid crystal layer 36) of the display member 18, and a ROM 30 that stores sound effect data; It consists of In the configuration in which different types of detection signals are output for each sensor 32, the ROM 30 indicates correspondence relationships (tables) between different types of detection signals for each sensor 32 and the incident site (liquid crystal layer 36) of the display member 18. It may be memorized.

  The CPU 24 specifies the incident position of the laser beam on the display member 18 based on the detection signals from the plurality of sensors 32. For example, when a laser beam is received by the sensor 32 disposed on the left side of the shooting region of the display member 18, a detection signal is output from the sensor 32 that has received the laser beam to the control device 22. Then, the CPU 24 recognizes the sensor 32 that has output this detection signal, refers to the table stored in the ROM 30, and specifies the incident position of the laser beam on the display member 18 (for example, the left liquid crystal layer 36). Alternatively, the CPU 24 may specify the sensor 32 according to the type of the detection signal, and thereby specify the incident position of the laser beam on the display member 18.

  The power supply circuit 26 applies a predetermined voltage to the incident position of the laser beam on the display member 18 specified by the CPU 24. Specifically, a predetermined voltage is applied between the transparent electrodes 50, 52, (62, 64), (74, 76) of the liquid crystal layer 36 at which the laser beam is incident. As a result, the color of the incident part of the display member 18 on which the laser beam is incident changes. The power supply circuit 26 is controlled by the CPU 24.

  The sound source circuit 28 outputs a predetermined sound effect via the speaker 20 based on the sound data of the sound effect stored in the ROM 30 at the same time when the laser beam is detected by any one of the plurality of sensors 32. . For this reason, the player hears the sound effect at the moment when the laser beam reaches the shooting area of the display member 18. The sound source circuit 28 is controlled by the CPU 24. The sound source circuit 28 controls the output of sound effects from the speaker 20.

Next, the configuration of the display member 18 will be described in detail.
As shown in FIG. 4, the display member 18 is composed of electronic paper 34 provided with a cholesteric liquid crystal material. The electronic paper 34 is configured by arranging a plurality of liquid crystal layers 36 in a so-called matrix on the same plane. That is, one liquid crystal layer 36 is a cell. In addition, the liquid crystal layers 36 adjacent on the same plane are fixed by an adhesive material such as an adhesive or a double-sided tape. In addition, a transparent sheet member (for example, a resin sheet) may be disposed on both front and rear sides of the electronic paper 34 (front and rear sides of the plurality of liquid crystal layers 36) to hold all the liquid crystal layers 36.

  Each liquid crystal layer 36 is formed by stacking blue, green, and red cholesteric liquid crystal materials in the thickness direction. Specifically, each liquid crystal layer 36 includes a blue cholesteric liquid crystal material layer 38 through which laser beams are transmitted, a green cholesteric liquid crystal material layer 40 through which laser beams are transmitted, a red cholesteric liquid crystal material layer 42 through which laser beams are transmitted, Are stacked in the thickness direction.

  Here, the cholesteric liquid crystal has a property of reflecting only a specific wavelength (light). When light such as sunlight or fluorescent light is incident on the liquid crystal, a predetermined wavelength of blue, green, or red is reflected to display in full color. When light of all colors of blue, green, and red is reflected, it becomes the three primary colors of light and appears white with the naked eye.

  The blue cholesteric liquid crystal material layer 38 includes a pair of transparent films 44 and 46 through which a laser beam and light are transmitted, a blue cholesteric liquid crystal material 48 interposed between the transparent films 44 and 46, and a pair of transparent films. And transparent electrodes 50 and 52 provided at the boundary between the surfaces of 44 and 46 and the blue cholesteric liquid crystal material 48. The blue cholesteric liquid crystal material 48 of each liquid crystal layer 36 is sealed with a sealant 54.

  The green cholesteric liquid crystal material layer 40 includes a pair of transparent films 56 and 58 through which a laser beam and light are transmitted, a green cholesteric liquid crystal material 60 interposed between the transparent films 56 and 58, and a pair of transparent films. And transparent electrodes 62 and 64 provided at the boundary between the surfaces of 56 and 58 and the green cholesteric liquid crystal material 60. The green cholesteric liquid crystal material 60 of each liquid crystal layer 36 is sealed with a sealant 66.

  The red cholesteric liquid crystal material layer 42 includes a pair of transparent films 68 and 70 through which laser light and light are transmitted, a red cholesteric liquid crystal material 72 interposed between the transparent films 68 and 70, and a pair of transparent films. And transparent electrodes 74 and 76 provided at the boundary between the surface of 68 and 70 and the red cholesteric liquid crystal material. The red cholesteric liquid crystal material of each liquid crystal layer 36 is sealed with a sealant 78.

  As described above, each liquid crystal layer 36 includes a blue cholesteric liquid crystal material layer 38 located on the most surface side, and a green cholesteric liquid crystal material layer 38 located on the back side (back side) of the blue cholesteric liquid crystal material layer 38. The red cholesteric liquid crystal material layer 42 positioned on the back (back) side of the green cholesteric liquid crystal material layer 40 is overlapped in the thickness direction. The display member 18 is configured by arranging a plurality of liquid crystal layers 36 having the above-described configuration on the same plane.

  Next, the principle of light reflection on the display member 18 will be described.

  As shown in FIGS. 5 and 6, a plurality of liquid crystal molecules X are arranged like a twisted spiral in the cholesteric liquid crystal material of each liquid crystal material layer 38, 40, 42. Usually, a plurality of liquid crystal molecules X are arranged in a vertical direction and reflect light such as sunlight or fluorescent lamps.

  As shown in FIGS. 5 and 7, a low voltage is applied between the transparent electrodes 50, 52, (62, 64), (74, 76) in a portion where light such as a laser beam, sunlight, or a fluorescent lamp is desired to pass. This is applied to make the spiral liquid crystal molecules X face sideways. Even when the application of this voltage is stopped (even when the power is turned off), the liquid crystal molecules X remain stable in the horizontal direction. Thereby, light, such as sunlight and a fluorescent lamp, passes through each liquid crystal material layer 38, 40, 42.

  Further, as shown in FIG. 5 and FIG. 8, a high voltage is applied between the transparent electrodes 50, 52, (62, 64), (74, 76) in the portion where light such as laser light, sunlight or fluorescent light is to be reflected. When applied, the spiral liquid crystal molecules X are stretched, and the voltage application is immediately stopped. Thereby, the liquid crystal molecules X are repelled and become a vertical spiral and are stabilized. Thereby, light, such as sunlight and a fluorescent lamp, reflects in this part.

  Here, the application of voltage is controlled by the power supply circuit 26. A voltage application signal is output from the power supply circuit 26 to the transparent electrodes 50, 52, (62, 64), (74, 76), and a voltage is applied based on this signal.

  Thus, by using the electronic paper 34 for the display member 18, a polarizing plate, a reflector, a color filter, and a backlight become unnecessary. For this reason, the number of parts of the display member 18 can be reduced, and the manufacturing cost can be reduced. Further, by using the electronic paper 34, display can be performed with low power.

  Next, a laser beam incident position display method in the laser beam incident position display device 10 according to the first embodiment of the present invention will be described. The present invention displays the incident position of the laser beam by utilizing the reflection principle of the electronic paper 34 as the display member.

  First, as shown in FIGS. 4 and 5, as the initial state of the display member 18, the transparent electrodes 50, 52, (62, 64), (74) of all the liquid crystal material layers 38, 40, 42 of the liquid crystal layer 36 are used. 76), a relatively low voltage is applied. This is because the power supply circuit 26 controlled by the CPU 24 applies a predetermined voltage to the transparent electrodes 50, 52, (62, 64), (74, 76) between all the liquid crystal material layers 38, 40, 42. It can be executed by applying. In the initial state of the display member 18, the liquid crystal molecules X are stable in the horizontal state shown in FIG. 7, and light such as laser light, sunlight, or fluorescent light passes through all the liquid crystal material layers 38, 40, 42. . At this time, the player visually recognizes black.

  Next, the game by the player is started. When a laser beam is irradiated from the player's simulated gun 12 and enters a part of the shooting region of the display member 18, the laser beam passes through all the liquid crystal material layers 38, 40, and 42, and enters one liquid crystal layer. Light is received by a sensor 32 located on the back side of 36. Then, a laser beam detection signal is output from the sensor 32 receiving the laser beam to the control device 22. In response to this detection signal, the CPU 24 identifies the sensor 32 that has received the laser beam, and identifies one liquid crystal layer 36 corresponding to the sensor 32. As will be described later, the specified one liquid crystal layer 36 changes its color as the position where the laser beam is incident.

  Next, the CPU 24 generates a control signal for applying a relatively high voltage between the transparent electrodes 50, 52, (62, 64), (74, 76) arranged in the specified liquid crystal layer 36. Output to the power supply circuit 26. At this time, the power supply circuit 26 receives a control signal from the CPU 24 and is relatively high with respect to the transparent electrodes 50, 52, (62, 64), (74, 76) of the specified one liquid crystal layer 36. Apply electrodes.

  As a result, the liquid crystal molecules X in the liquid crystal material corresponding to the transparent electrodes 50, 52, (62, 64), (74, 76) to which a voltage is applied are in the vertically oriented state shown in FIG. And stable, and reflects light such as sunlight and fluorescent lamps. In addition, the voltage application time between the transparent electrodes 50, 52, (62, 64), and (74, 76) at this time is a short time, and the voltage application is stopped immediately after the voltage is applied.

  As a result, the liquid crystal layer 36 having the transparent electrodes 50, 52, (62, 64), (74, 76) to which a voltage is applied is changed to a property of reflecting light such as sunlight or fluorescent lamps, The person recognizes the color change. Specifically, when a high voltage is applied between the transparent electrodes 50 and 52 of the blue cholesteric liquid crystal material layer 38, the incident position of the laser beam is displayed in blue, and the player can see that the blue portion is the laser beam. Recognized as an incident position. In addition, when a high voltage is applied between the transparent electrodes 62 and 64 of the green cholesteric liquid crystal material layer 40, the incident position of the laser beam is displayed in green, and the player determines that the green portion is the incident position of the laser beam. recognize. When a high voltage is applied between the transparent electrodes 74 and 76 of the red cholesteric liquid crystal material layer 42, the incident position of the laser beam is displayed in red, and the player recognizes the red portion as the incident position of the laser beam. .

  More specifically, when the incident position of the laser beam is displayed in blue, a high voltage is applied between the transparent electrodes 50 and 52 of the blue cholesteric liquid crystal material layer 38, and the green and red cholesteric liquid crystal material layers 40 and 42 are displayed. No voltage is applied between the transparent electrodes 62 and 64 (74, 76). For this reason, the liquid crystal molecules X of the blue cholesteric liquid crystal material layer 38 reflect light because they are stable in the vertical orientation shown in FIG. 8, and the liquid crystal molecules X of the green and red cholesteric liquid crystal material layers 40 and 42 are Light is transmitted in order to stabilize in the horizontal state shown in FIG.

  When the incident position of the laser beam is displayed in green, a high voltage is applied between the transparent electrodes 62 and 64 of the green cholesteric liquid crystal material layer 40, and the transparent electrodes of the blue and red cholesteric liquid crystal material layers 38 and 42 are displayed. A voltage is not applied between 50 and 52 (74, 76). For this reason, the liquid crystal molecules X of the green cholesteric liquid crystal material layer 40 reflect light in order to stabilize in the vertical orientation shown in FIG. 8, and the liquid crystal molecules X of the blue and red cholesteric liquid crystal material layers 38 and 42 are Light is transmitted in order to stabilize in the horizontal state shown in FIG.

  Further, when the incident position of the laser beam is displayed in red, a high voltage is applied between the transparent electrodes 74 and 76 of the red cholesteric liquid crystal material layer 42, and the transparent electrodes of the blue and green cholesteric liquid crystal material layers 38 and 40 are displayed. A voltage is not applied between 50 and 52 (62, 64). Therefore, the liquid crystal molecules X of the red cholesteric liquid crystal material layer 42 are reflected in order to stabilize in the vertical orientation shown in FIG. 8, and the liquid crystal molecules X of the blue and green cholesteric liquid crystal material layers 38 and 40 are Light is transmitted in order to stabilize in the horizontal state shown in FIG.

  In addition, when displaying the incident position of a laser beam in colors other than blue, green, and red, the transparent electrodes 50, 52, (62, 64), (74, 76) of the cholesteric liquid crystal material layers 38, 40, 42 of the respective colors. ) Can be dealt with by appropriately changing the voltage application pattern. For example, a high voltage is applied between the transparent electrodes 50 and 52 (62 and 64) of the blue and green cholesteric liquid crystal material layers 38 and 40, and a voltage is applied between the transparent electrodes 74 and 76 of the red cholesteric liquid crystal material layer 42. By not, blue and green light can be reflected, and the incident position of the laser beam can be displayed in a mixed color of blue and green. On the other hand, a high voltage is applied between the transparent electrodes 50 and 52 (74 and 76) of the blue and red cholesteric liquid crystal material layers 38 and 42, and a voltage is applied between the transparent electrodes 62 and 64 of the green cholesteric liquid crystal material layer 40. By not doing so, blue and red light can be reflected, and the incident position of the laser beam can be displayed in a mixed color of blue and red. Further, a high voltage is applied between the transparent electrodes 62 and 64 (74 and 76) of the green and red cholesteric liquid crystal material layers 40 and 42, and a voltage is applied between the transparent electrodes 50 and 52 of the blue cholesteric liquid crystal material layer 38. By not doing so, green and red light can be reflected, and the incident position of the laser beam can be displayed in a mixed color of green and red. Further, by applying a high voltage to the transparent electrodes 50, 52, (62, 64), (74, 76) of the blue, green and red cholesteric liquid crystal material layers 38, 40, 42, blue, green and red The light can be reflected, and the incident position of the laser beam can be displayed in a mixed color of blue, green and red. In this manner, the voltage application pattern (application ON / OFF) between the transparent electrodes 50, 52, (62, 64), (74, 76) of the cholesteric liquid crystal material layers 38, 40, and 42 of the respective colors is appropriately changed. Thus, the incident position of the laser beam can be displayed in various colors, and a predetermined pattern can be displayed.

  At the same time, when any one of the sensors receives the laser beam, the CPU 24 outputs a control signal for outputting a predetermined sound effect to the sound source circuit 28. At this time, the sound source circuit 28 receives a control signal from the CPU 24 and outputs a predetermined sound effect via each speaker 20 based on the sound effect data stored in the ROM 30. The sound effect may be changed depending on the portion of the shooting area where the laser beam is incident. For example, when a laser beam is incident on the center of the shooting area, a large sound effect is output, and when a laser beam is incident on a part away from the center of the shooting area, a small sound effect is output. May be.

  As described above, according to the laser beam incident position display device 10 of the first embodiment, a projector, a video camera (CCD camera), and the like are no longer necessary, and can be manufactured with a simple configuration and at low cost. Further, the laser beam incident position display device 10 can be installed and used even in a narrow space. Furthermore, by using the electronic paper 34 as the display member 18, the electronic paper 34 can be assembled using the flexibility of the electronic paper 34, and the laser beam incident position display device 10 can be reduced in size and weight. Can do.

  In addition, although the example comprised by the cholesteric liquid crystal material layer 38, 40, 42 of multiple colors (three colors) was shown as the display member 18, it is not restricted to this structure, A monochromatic (for example, red) cholesteric liquid crystal is shown. The display member may be composed of only the material layer, or the display member may be composed of two colors (blue and red) of cholesteric liquid crystal material layers.

  Next, a laser beam incident position display device according to a second embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the structure which overlaps with the structure of the laser beam incident position display apparatus concerning 1st Embodiment, and the description is abbreviate | omitted suitably.

  The laser beam incident position display apparatus according to the second embodiment is different from the first embodiment in the configuration of the display member.

  As shown in FIG. 9, a microcapsule-type electrophoretic electronic paper 100 is used for the display member 18. The electronic paper 100 is configured by arranging a plurality of electronic ink layers 102 in a so-called matrix on the same plane. That is, one electronic ink layer 102 is a cell. Note that the adjacent electronic ink layers 102 on the same plane are fixed by an adhesive material such as an adhesive or a double-sided tape. In addition, a transparent sheet member (for example, a resin sheet) is disposed on both front and rear sides of the electronic paper 100 (electronic ink layer 102) (front and rear sides of the plurality of electronic ink layers 102), and all the electronic ink layers 102 are disposed. You may make it hold | maintain.

  That is, each electronic ink layer 102 includes a transparent surface electrode (transparent electrode) 104 located on the front surface side (player side), a transparent back electrode (transparent electrode) 106 located on the back surface (back surface) side, A plurality of transparent microcapsules 108 interposed between the electrode 104 and the back electrode 106 are configured. The power supply circuit 26 applies a predetermined voltage between the front electrode 104 and the back electrode 106. The laser beam passes through the surface electrode 104, the microcapsule 108, and the back electrode 106.

  Here, a positively charged white pigment 110 (particles) and a negatively charged black pigment 112 (particles) are accommodated in the microcapsule 108. The positively charged white pigment 110 is attracted to the negatively charged electrode side, and the negatively charged black pigment 112 is attracted to the positively charged electrode side.

  That is, as shown in FIG. 9A, when the back electrode 106 is positively charged, the black pigment 112 moves to the back electrode 106 side, and the white pigment 110 moves to the front electrode 104 side. For this reason, the player recognizes white. 9B, when the back electrode 106 is negatively charged, the white pigment 110 moves to the back electrode 106 side, and the black pigment 112 moves to the front electrode 104 side. For this reason, the player recognizes black. Further, as shown in FIG. 9C, when the back electrode 106 is positively and negatively charged, the black pigment 112 and the white pigment 110 move to the back electrode 106 side, and the white color to the front electrode 104 side. The pigment 110 and the black pigment 112 move. For this reason, the player recognizes it as a mixed color of black and white.

  The microcapsules 108 are provided over the entire area of the shooting area. Each sensor 32 is provided on the back side of each microcapsule 108 so as to correspond to each microcapsule 108. For this reason, when the laser beam passes through the microcapsule 108 positioned in front, the sensor 32 positioned on the back side receives the laser beam. When the sensor 32 receives the laser beam, a detection signal is output from the sensor 32 to the control device 22. The CPU 24 receives the detection signal from the sensor 32, specifies the microcapsule 108 through which the laser beam has passed, and sends a control signal for applying a predetermined voltage between the specified electrodes 104, 106 to the power supply circuit 26. Output. At the same time, the CPU 24 outputs a control signal for outputting a predetermined sound effect to the sound source circuit 28.

  Here, as shown in FIG. 9A, the back electrode 106 side is positive (plus) and the front electrode 104 side is between the surface electrode 104 and the back electrode 106 corresponding to the microcapsule 108 through which the laser beam has passed. Apply voltage so that it is negative. As a result, an electric field is generated between the front electrode 104 and the back electrode 106. This electric field is directed from the back electrode 106 side to the surface electrode 104 side. Since the back electrode 106 side becomes positive (plus) and the front electrode 104 side becomes negative (minus), the positively charged white pigment 110 moves to the front electrode 104 side, and the negatively charged black pigment 112 becomes Then, it moves to the back electrode 106 side. As a result, the shooting area where the laser beam is incident is displayed in white, and the player recognizes the incident position of the laser beam on the shooting area.

  On the other hand, as shown in FIG. 9B, the surface electrode 104 side is positive (plus) and the back electrode 106 side is negative with respect to the space between the surface electrode 104 and the back electrode 106 corresponding to the microcapsule 108 through which the laser beam has passed. You may apply a voltage so that it may become (minus). As a result, an electric field is generated between the front electrode 104 and the back electrode 106. This electric field is directed from the surface electrode 104 side to the back electrode 106 side. For this reason, since the front electrode 104 side becomes positive (plus) and the back electrode 106 side becomes negative (minus), the positively charged white pigment 110 moves to the back electrode 106 side and negatively charged black pigment 112. Moves to the surface electrode 104 side. As a result, the shooting area where the laser beam is incident is displayed in black, and the player recognizes the incident position of the laser beam on the shooting area.

  Further, as shown in FIG. 9C, a part on the surface electrode 104 side and a part on the back electrode 106 side are provided between the surface electrode 104 and the back electrode 106 corresponding to the microcapsule 108 through which the laser beam is transmitted. A voltage may be applied so that the portion becomes positive (plus). As a result, an electric field is generated between the front electrode 104 and the back electrode 106. In this case, there are two types of electric fields, that is, an electric field directed from the back electrode 106 side to the surface electrode 104 side and an electric field directed from the surface electrode 104 side to the back electrode 106 side. Therefore, a part on the back electrode 106 side is positive (plus), a part is negative (minus), a part on the surface electrode 104 side is positive (plus), and a part is negative (minus). As a result, the surface electrode 104 side becomes positive (plus) and negative (minus), so that part of the positively charged white pigment 110 and part of the negatively charged black pigment 112 move to the surface electrode 104 side. . At the same time, since the back electrode 106 side is also positive (plus) and negative (minus), a part of the positively charged white pigment 110 and a part of the negatively charged black pigment 112 are moved to the surface electrode 104 side. To do. As a result, the shooting area where the laser beam is incident is displayed in a mixed color of black and white, and the player recognizes the incident position of the laser beam on the shooting area.

  According to the second embodiment, the incident position of the laser beam can be easily displayed even when the electronic paper 100 of the microcapsule type electrophoresis system (electronic ink layer 102) is used as the display member 18.

  Next, a laser beam incident position display device according to a third embodiment of the invention will be described. In addition, the same code | symbol is attached | subjected to the structure which overlaps with the structure of the laser beam incident position display apparatus concerning 1st Embodiment, and the description is abbreviate | omitted suitably.

  The laser beam incident position display apparatus according to the third embodiment is different from the first embodiment in the configuration of the display member.

  As shown in FIG. 10, an organic EL display 200 is used for the display member 18. The organic EL display 200 includes a plurality of organic EL layers 202 arranged on the same plane. That is, one organic EL layer 202 is a cell. The adjacent organic EL layers 202 on the same plane are fixed by an adhesive material such as an adhesive or a double-sided tape. In addition, a transparent sheet member (for example, a resin sheet) is disposed on both front and rear sides of the organic EL display 200 (organic EL layer 202) (front and rear sides of the plurality of organic EL layers 202), and all the organic EL layers 202 are disposed. May be held.

  Each organic EL layer 202 includes a glass substrate 204 positioned on the player side, a transparent surface electrode (transparent electrode) 206, a transparent back electrode (transparent electrode) 208, and between the surface electrode 206 and the back electrode 208. A positive charge transport layer 210 positioned adjacent to the front electrode 206, a negative charge transport layer 212 positioned between the front electrode 206 and the back electrode 208 and adjacent to the back electrode 208, and a positive charge transport layer 210 And a light emitting layer 214 interposed between the negative charge transport layer 212 and the negative charge transport layer 212. A predetermined voltage is applied between the surface electrode 206 and the back electrode 208 by the power supply circuit 26. Each sensor 32 for detecting a laser beam is disposed on the back side of each organic EL layer 202 so as to correspond to each organic EL layer 202.

  According to the third embodiment, a predetermined voltage is applied between the surface electrode 206 and the back electrode 208 of the organic EL layer 202 located on the front side of the sensor 32 that has received the laser beam. When a predetermined voltage is applied between the front electrode 206 and the back electrode 208, positive charges (holes) in the positive charge transport layer 210 and negative charges (electrons) in the negative charge transport layer 212 are generated. It flows into the light emitting layer 214. Then, a positive charge and a negative charge are recombined in the light emitting layer 214 to generate an excited state of the organic molecule, and light is emitted when it returns to a stable state. Thereby, the organic EL layer 202 on which the laser beam is incident emits light, and the player recognizes the incident position of the laser beam. Note that the organic EL layer 202 on which no laser beam is incident does not emit light, and therefore is not recognized by the player. As a result, only the organic EL layer 202 on which the laser beam is incident emits light, so that the organic EL (incident position) on which the laser beam is incident becomes clear even if a plurality of organic EL layers 202 are present.

  As described above, by using the organic EL display 200 for the display member 18 that displays the incident position of the laser beam, the organic EL display 200 can be assembled using the flexibility of the organic EL display 200, and the laser beam.
