  The casing 31 is a box having a rectangular parallelepiped shape, and an opening is provided at a predetermined position. An opening 31A is provided in the upper portion of the wall portion on the front side of the housing 31 (upward direction perpendicular to the paper surface of FIG. 2, left side of FIG. 3), and the soft air gun is provided through the opening 31A. A BB bullet fired by (not shown) is introduced into the housing 31. Further, an opening 31B similar to that on the front side is provided on the wall portion on the back side of the casing 31 (downward direction perpendicular to the paper surface in FIG. 2, right side in FIG. 3), and closes the opening portion 31B. Thus, the back plate 32 is mounted.

  In addition, an opening 31C for inserting the target plate 22 is provided on the front side of the upper wall portion of the housing 31, and the target plate 22 having a shape slightly wider than the opening 31A is provided in the housing 31.

In addition, an opening 31D for inserting the drawer 38 is provided below the wall portion on the right side surface of the housing 31.

  The back plate 32 is mounted in the opening 31B on the back side of the housing 31 so that the target paper 21 is sandwiched between the housing 31 so that the target of the target paper 21 faces the front side of the target device 12. Is done. The back plate 32 is a transparent plate and is detachable. The target paper 21 can be easily exchanged according to the shooting competition, and a sub-monitor 71 (FIG. 14) described later can be used. It becomes possible. In addition, the rear plate 32 extends the upper portion, makes a hole in the extended portion, and can be hung on the hook, so that the target device 12 can be hung on the wall, or the rear plate 32 is expanded vertically and horizontally. A device that can protect the periphery of the target device 12 to a certain range may be prepared as an option.

  The upper lid 33 has a function of closing the opening 31C for inserting the target plate 22 and pressing the target plate 22 housed in the housing 31 from above. FIG. 3 shows a state in which the upper lid 33 closes the opening 31C on the upper side of the housing 31. After the upper lid 33 is removed and the target plate 22 is inserted from the opening 31C, the lower surface of the upper lid 33 is shown. The upper lid 33 is attached and fixed with screws 33a so that the upper lid 33 comes into contact with the upper end of the target plate 22, and the upper lid 33 presses and fixes the target plate 22 from above. Further, the front edge of the upper lid 33 is formed with a bent portion 45a that is bent toward the inner side of the housing 31 with a width of 3.5 mm and an inclination angle of 45 °, for example. Similarly to the bent portion 45 a, bent portions 45 b and 45 c that are bent toward the inside of the housing 31 are also formed at the front edge portions on both sides of the opening 31 </ b> A of the housing 31.

  The reflectors 34, 35, and 37 are, for example, polycarbonate plate-like members having a thickness of 2 mm. The reflection plate 36 is, for example, an iron plate-like member having a thickness of 0.8 mm. The reflectors 34 to 37 are fixed inside the housing 31 so as to have a predetermined inclination angle. The inclination angles will be described later with reference to FIG.

  The target plate 22 and the reflection plate 34 are fixed inside the housing 31 at an inclination angle such that the interval is narrowed from the front side toward the lower side on the back side. In addition, the distance D between the inlets 101, which is a space formed in a place where the distance between the target plate 22 and the reflecting plate 34 is the narrowest, is set to 10 mm, for example. In addition, a region ahead of the entrance 101 in the direction along the trajectory of the BB bullet indicated by the one-dot chain line in FIG.

  The drawer 38 is a long and narrow box formed of a transparent resin and having an upper surface opened. The drawer 38 is inserted into and removed from the opening 31 </ b> D on the right side surface of the housing 31. The drawer 38 accommodates the BB bullet reflected by the target plate 22 and the reflection plates 34 to 37. Also, an elongated window portion 41 is formed on the lower side of the wall portion on the front side of the housing 31, and the amount of BB bullets accommodated in the drawer 38 can be confirmed via the window portion 41. Has been.

  The communication terminal 39 is a terminal for connecting the communication cable 15 of FIG. 1 to the target device 12 and is electrically connected to the signal processing unit 24. For example, when the communication cable 15 is a USB cable, the communication terminal 39 is a USB connector. Further, as shown in FIG. 3, the signal processing unit 24 is mounted on the target device 12 by a printed board.

  The LED 40 is connected to the communication terminal 39 and the communication cable 15 is connected, and the LED 40 is lit according to a command from a program executed in the personal computer 13 via the communication cable 15.

  Further, for example, as shown in FIGS. 13 and 14 to be described later, a through hole is formed in the center of the lower wall portion of the casing 31 so that the target device 12 can be fixed to the tripod 72. The nut 42 is fixed in accordance with the through hole.

  As described above, in the target device 12, as shown in FIGS. 2 and 3, the target plate 22 and the reflection plate 34 are inclined at an inclination angle such that the interval decreases from the front side to the lower side of the back side. It is fixed inside. Therefore, in the target device 12, the BB bullet that hits the target plate 22 moves toward the entrance 101 of the accommodation region 102 while repeatedly bouncing between the target plate 22 and the reflection plate 34, as shown by a dashed line. Be guided.

  Further, in the target device 12, the BB bullets that have passed through the entrance 101 of the containing area 102 will repeatedly bounce inside the containing area 102, and the kinetic energy of the BB bullets is attenuated. It is prevented. Thereby, the target device 12 can securely store the BB bullet in the drawer 38.

  Thus, the inclination angle of the target plate 22 and the reflection plate 34 for reliably collecting the BB bullets was obtained by performing a test for measuring the rebound angle of the BB bullets while changing the angle of the target plate 22.

  The relationship between the angle of the target plate 22 and the rebound angle will be described with reference to FIG.

  FIG. 4 shows a front view (FIG. 4A) and a side view (FIG. 4B) of the target plate 22 fixed at a predetermined angle, and the angle between the target plate 22 and the horizontal plane is the target plate angle θ. The angle at which the BB bullet hitting the target plate 22 bounces is defined as the bounce angle γ. The angle of the trajectory where the BB bullets are incident on the target plate 22 with respect to the normal of the target plate 22 is the incident angle α, and the trajectory of the trajectory after the BB bullets have bounced back on the target plate 22 The angle is the reflection angle β. That is, the following formula is established.

      γ = α + β (1)

  Here, measurement results of the bounce angle γ, the incident angle α, and the reflection angle β when a polycarbonate plate having a thickness of 2 mm is used as the target plate 22 will be described. FIG. 5A shows the result of measurement using a soft air gun (for 18 years old and over) with an energy of 0.4 J and firing a BB bullet weighing 0.2 g. FIG. 5B shows a result of measurement using a soft air gun (for 10 years old and over) with an energy of 0.09 J and firing a BB bullet weighing 0.12 g.

  5A and 5B, when the target plate angle θ is the same, the case where a heavier BB bullet is fired with a higher energy air gun (in the case of FIG. 5A) is smaller. The rebound angle γ is larger than when a lighter BB bullet is fired with an energy air gun (in the case of FIG. 5B). However, when it exceeds a certain level, the change decreases, and even when a soft air gun with an energy of 0.8 J is used or when a BB bullet weighing 0.25 g or 0.3 g is used, the reflection angle is smaller than the result of FIG. 5A. The increase was slight. In addition, it is assumed that the weight of the BB bullet, the rigidity of the target plate 22 or the friction coefficient also affects the reflection angle.

  In this way, by repeatedly performing the experiment of measuring the rebound angle γ while changing the target plate angle θ, the entrance of the accommodation region 102 while the BB bullet rebounds between the target plate 22 and the reflection plate 34 of FIG. 3. An inclination angle that is reliably guided toward 101 is obtained.

  In addition, as shown in FIG. 5, it was confirmed that the reflection angle β is larger than the incident angle α. This is based on the fact that, unlike light reflection, the rebound angle when solids collide changes depending on the shape, material, surface shape, etc. of the solid. When the target plate 22 and the BB bullet, both of which are considered to have a small friction coefficient, hit at an angle, the BB bullet rolls and slides on the surface of the target plate 22 and the target plate 22 is locally bent. Therefore, it is considered that the reflection angle β is surely increased. Actually, it was confirmed that the BB bullet immediately after being collected by the target device 12 was violently rotating.

  Further, in order to confirm the influence of the thickness of the target plate 22 on the reflection angle β of the BB bullet, the rebound angle γ is about 90 ° with respect to the polycarbonate plates having a thickness of 2 mm, 3 mm, 5 mm, and 10 mm. The target plate angle θ was measured. For example, in a soft air gun with an energy of 0.5 J and a BB bullet with a weight of 0.2 g and a diameter of 6 mm, a polycarbonate plate with a thickness of 2 mm has a target plate angle θ of 72 ° and a thickness of 3 mm. For a polycarbonate plate, the target plate angle θ is 63 °, for a 5 mm thick polycarbonate plate, the target plate angle θ is 53 °, and for a 10 mm thick polycarbonate plate, the target plate angle θ is 49 °. It was measured.

  And, it is considered that no bending occurs at all on the polycarbonate plate having a thickness of 10 mm, and the rebound angle γ when the rolling and slipping of the BB bullets on the surface of the target plate 22 does not occur is 45 °. Then, it is considered that the influence of rolling and slipping of the BB bullet on the reflection angle β, that is, the increase in the reflection angle β is 4 ° (= 49 ° -45 °). Therefore, it is assumed that most of the cause of the increase in the reflection angle β in the polycarbonate target plate 22 having a thickness of 2 mm is due to local bending of the target plate 22.

  Further, when the influence of the change in the weight and energy of the BB bullet on the reflection angle β is examined on the polycarbonate plates having different thicknesses, the weight and energy of the BB bullet are obtained when the thickness of the plate is 10 mm. However, when the thickness of the plate was 2 mm, only the change in the weight of the BB bullet had a great effect.

  For example, as described above, when a BB bullet having a weight of 0.2 g and a diameter of 6 mm is used with a soft air gun having an energy of 0.5 J on a polycarbonate plate having a thickness of 2 mm, the rebound angle γ is about The target plate angle θ at 90 ° was 72 °. Further, when a soft air gun having an energy of 0.09 J was used under the same conditions, the target plate angle θ at which the rebound angle γ was about 90 ° was 71 °. Therefore, between the soft air gun with energy 0.5J and the soft air gun with energy 0.09J, the difference in the target plate angle θ at which the rebound angle γ is about 90 ° is 1 °, and the difference in energy of the soft air gun However, the influence on the target plate angle θ at which the rebound angle γ is about 90 ° is relatively small.

  On the other hand, as shown in FIG. 5B, when a BB bullet having a weight of 0.12 g and a diameter of 6 mm is fired using a soft air gun having an energy of 0.09 J, a target plate having a rebound angle γ of about 90 °. The angle θ was 67 °. Thus, there is a difference of 5 ° in the target plate angle θ at which the rebound angle γ is about 90 ° between the BB bullet weighing 0.2 g and the BB bullet weighing 0.12 g. The effect of the difference on the target plate angle θ at which the rebound angle γ is about 90 ° is relatively large. Therefore, if the target plate 22 is a polycarbonate plate having a thickness of 2 mm, the rebound angle γ of the BB bullet is almost determined by the weight of the BB bullet, and the influence of the energy of the soft air gun is relatively small. It can be said that.

  In general, a BB bullet weighing 0.2 g or more is used for a soft air gun for 18 years old or older, and a BB bullet weighing 0.12 g is used for a soft air gun for 10 years old or older and 7 years old or older. Yes. Thus, by designing the target device 12 for 18 years or older based on the data of FIG. 5A and designing the target device 12 for 10 years or older and 7 years or older based on the data of FIG. Even if the soft air gun is used, the BB bullets can be reliably recovered. If there is no problem even if the depth of the target device 12 increases, the target device 12 for all ages 7 years and older can be designed based on the data of FIG. 5B.

  In addition, in order to estimate the reflection angle at each reflection point of the path shown in FIG. 6 when it is assumed that the reflection angle changes depending on the energy because the energy attenuates every time the BB bullet bounces, each reflection point It is necessary to measure data as shown in FIG. However, if the target plate 22 is a polycarbonate plate having a thickness of 2 mm and the target plate angle θ is the same, the rebound angle of the BB bullet is almost determined by the weight of the BB bullet, and therefore based on the data of FIG. 5A. All the reflection paths shown in FIG. 6 can be estimated almost accurately.

  Next, with reference to FIG. 6, the inclination angle of the target plate 22 and the reflection plate 34 and the path of the BB bullet inside the target device 12 will be described. FIG. 6 shows a schematic configuration of the target device 12. In FIG. 6, the left side is the front side of the target device 12 and the right side is the back side of the target device 12.

  The target plate 22 is fixed at an inclination angle of 68 ° (θ = 68 °) with respect to the wall portion on the upper surface of the housing 31 so as to go from the front side to the back side as it goes from the upper side to the lower side of the target device 12. Has been. In addition, the upper end of the target plate 22 is in contact with the vicinity of the front side end of the upper wall of the casing 31, and the lower end is the lower end of the wall on the back side of the casing 31. It is fixed so as to contact the vicinity of the part.

  The reflection plate 34 is fixed at an inclination angle of 68 ° with respect to the wall portion on the front side of the housing 31 so as to go from the front side to the back side as it goes from the upper side to the lower side of the target device 12. Further, the reflector 34 is disposed below the opening 31A on the front side of the housing 31, the end on the front side abuts on the wall on the front side of the housing 31, and the end on the back side is It fixes so that it may become a predetermined space | interval (distance D shown in FIG. 3) between the target plates 22.

  Therefore, in the configuration example of FIG. 6, the target device 12 is configured such that the angle between the target plate 22 and the reflection plate 34 is 46 ° (= 68 ° − (90 ° −68 °)) from the front side to the back side. It is comprised so that the space | interval of the target plate 22 and the reflecting plate 34 may become narrow below.

  The reflection plate 35 is fixed at an inclination angle of 55 ° with respect to the horizontal plane so as to go from the back side to the front side as it goes from the upper side to the lower side of the target device 12. The inclination angle of the reflecting plate 35 is set to an angle that reflects the BB bullet that has passed through the entrance 101 of the receiving area 102 to the receiving area 102. In addition, the reflection plate 35 is fixed so that the upper end thereof is in contact with the lower end of the target plate 22. In addition, the reflecting plate 35 is affixed on a part of thin plate which comprises the reflecting plate 36 via the cushion material 43 provided with adhesiveness on both surfaces, for example.

  The reflection plate 36 is fixed at an inclination angle of 5 ° with respect to the horizontal plane so that the reflection plate 36 moves from the back side to the front side as it goes from the upper side to the lower side of the target device 12, that is, the BB bullet rolls into the drawer 38. Has been. As shown in FIG. 6, the reflecting plate 36 is constituted by a part of the thin plate (surface of the central portion) bent at at least two locations 36A and 36B when viewed from the side.

  The reflection plate 37 is fixed so as to be parallel to the wall portion on the front side of the housing 31. Moreover, the reflecting plate 37 is stuck to the inside of the wall portion on the near side of the housing 31 via, for example, a cushion material 44 having adhesiveness on both sides.

  As described above, the target plate 22 and the reflection plates 34 to 37 are fixed inside the casing 31, and the BB bullets fired toward the target device 12 repeats a plurality of rebounds, and the inside of the accommodation region 102. Is housed in a drawer 38 (FIG. 3).

  In FIG. 6, the path of the BB bullets fired horizontally toward the center of the target plate 22 is indicated by a one-dot chain line. The BB bullets fired horizontally collide with the target plate 22 at an incident angle of 22 °, bounce off with a reflection angle of 76 °, and then collide with the reflector plate 34 with an incident angle of 30 °. Rebounds at 80 °. Thereafter, the BB bullet collides with the target plate 22 at an incident angle of 33 °, rebounds at a reflection angle of 81 °, and passes through the entrance 101 of the accommodation region 102.

  That is, the inclination of the target plate 22 is such that the rebound angle γ of the BB bullet incident horizontally on the target plate 22 is greater than 90 °, that is, the reflection direction of the BB bullet is not the front side but the back side. An angle is set. Further, the inclination angle of the reflecting plate 34 is set so that the BB bullet reflected by the target plate 22 is incident from the front side from the vertical line and is reflected from the vertical line to the back side. Further, the inclination angle of the target plate 22 is set so that the BB bullet reflected by the reflecting plate 34 enters from the front side from the vertical line and reflects in the direction from the vertical side to the back side. The BB bullet is reflected twice by the target plate 22 and reflected only once by the reflecting plate 34 and enters the inlet 101. Thereby, it is prevented that the reflected BB bullet goes to the front side and becomes difficult to collect.

  Further, the BB bullet collides with the reflecting plate 35 at an incident angle of 42 °, bounces off with a reflecting angle of 83 °, then collides with the reflecting plate 36 with an incident angle of 45 °, and has a reflecting angle of 67 °. rebound. Here, as described above, since the reflection plate 36 is made of an iron plate, the reflection angle is different from that of the reflection plates 34, 35, and 37 made of a polycarbonate plate. In addition, the reflection angle of the reflecting plate 36 is also obtained by conducting an experiment. In the configuration in which the reflecting plate 35 is directly attached to the reflecting plate 36 without using the cushion material 43, the reflection angle at the reflecting plate 35 is substantially the reflection angle of an iron plate.

  Thereafter, the BB bullets are repeatedly bounced back to the reflecting plate 34, the reflecting plate 37, etc. in the accommodating area 102, and are accommodated in the drawer 38 (FIG. 3) in the casing 31 (accommodating area 102).

  As described above, in the target device 12, the user visually recognizes the target of the target paper 21 through the transparent target plate 22, and thus does not land on the target paper 21. Therefore, the target paper 21 does not need to be frequently replaced and can be used continuously. Further, since the target plate 22 and the reflection plates 34 to 37 are arranged at an appropriate inclination angle, the BB bullets fired horizontally toward the center of the target plate 22 are surely placed on the drawer 38 in the housing 31. Is housed in. That is, since the energy of the BB bullet is attenuated each time it is bounced off by the target plate 22 and the reflecting plates 34 to 37, in the configuration of the target device 12, it will bounce at least seven times before it fits in the drawer 38. When entering, the energy of the BB bullet is greatly attenuated. As a result, the BB bullet can be reliably accommodated even in a narrow space, and the target device 12 that can reliably accommodate the BB bullet can be reduced in size.

  In addition, even when the target device 12 is other than the case where the BB bullet is fired horizontally toward the center of the target plate 22, the target device 12 rebounds between the target plate 22 and the reflection plate 34 and enters the entrance 101 of the accommodation region 102. BB bullets can be guided to the storage area 102 and the BB bullets can be securely stored in the storage area 102.

  For example, FIG. 7 shows a path of a BB bullet that is horizontally launched toward the vicinity of the upper end and the lower end of the target plate 22 in addition to the center of the target plate 22. Further, FIG. 8 shows a path of a BB bullet fired from 20 ° (= 68 ° − (90 ° −42 °)) obliquely upward toward the center of the target plate 22. As shown in FIGS. 7 and 8, the path converges every time the BB bullet bounces between the target plate 22 and the reflecting plate 34, and after the three bounces, the same path as described in FIG. It becomes a route and is accommodated in the accommodation area 102.

  In this way, the target device 12 is configured so that, regardless of where the BB bullet hits the target plate 22 or even at a certain angle other than horizontal, Since the trajectories are almost completely aligned, irregularities do not occur, and BB bullets can be reliably recovered. As described above, since all the BB bullets can be collected, the use of the target device 12 can eliminate the troublesome collection of the BB bullets.

  Further, the target device 12 is often used by being placed on a desk or table, and it is considered that the target device 12 is often aimed at an angle from above (so that the incident angle α is larger than 22 °). However, because of the structure of the target device 12, it does not bounce upward diagonally, so that BB bullets fired at any angle can be reliably recovered from diagonally upward. Further, the target device 12 can collect any BB bullets launched at an angle of up to 10 ° (incident angle α = 12 ° = 22 ° −10 °) with respect to the horizontal.

  The target device 12 is designed on the assumption that a BB bullet having a weight of 0.2 g or more and a diameter of 6 mm is used, and the BB bullet can be reliably recovered under this use condition. On the other hand, under the use conditions in which a BB bullet having a weight of 0.12 g is used, the reflection angle differs, and it is necessary to change the tilt angle in order to reliably collect the BB bullet. For example, under this use condition, the angle of inclination (target plate angle θ) of the target plate 22 with respect to the horizontal plane is changed to 63 °, and the angle of inclination of the reflecting plate 34 with respect to the horizontal plane is changed to 27 °, so It can be recovered. In the target device 12, since the distance D between the inlets 101 is set to 10 mm, even when a BB bullet having a diameter of 8 mm is used, the BB bullet can be reliably collected.

  Thus, the inclination angle (target plate angle θ) of the target plate 22 is not limited to 68 ° shown in FIGS. 6 to 8. For example, the reflection angle β varies somewhat depending on the rigidity of the target plate 22. For this reason, in the state where the target plate 22 is fixed to the housing 31, it is assumed that the reflection angle β is slightly reduced in the peripheral portion of the target plate 22. When the reflection angle β is reduced, the reflection direction of the BB bullet is closer to the front direction than the rear direction of the housing 31. From this, in order to collect BB bullets reliably, it is considered that the inclination angle (target plate angle θ) of the target plate 22 is limited to about 70 °.

  As will be described later with reference to FIG. 11, when the monitor 14 is arranged and used on the back side of the target device 12, in order not to leave a gap between the target plate 22 and the monitor 14, It is desirable to design the target device 12 to be thin. Further, if the target plate angle θ is reduced, the recovery is easy, but the length of the casing 31 in the depth direction is increased, and the size is increased. Therefore, when the target plate 22 is a polycarbonate plate having a thickness of 2 mm, the inclination angle is preferably in the range of 60 ° to 70 °. As described above, the reflection angle β of the BB bullet varies depending on the thickness of the target plate 22. For example, when the target plate 22 is a polycarbonate plate having a thickness of 3 mm, The target plate angle θ needs to be 62 ° or less.

  Next, an example of a method for fixing the target plate 22 and the reflecting plates 34 to 37 will be described with reference to FIG.

  The target plate 22 is fixed so as to be sandwiched from both sides by pressing plates 51 and 52 fixed inside the side surface of the housing 31. In FIG. 9, two pressing plates 51 and 52 arranged on the left side surface of the casing 31 are shown, but two pressing plates are similarly arranged on the right side surface of the casing 31. The

  The holding plates 51 and 52 are fixed inside the side surface of the housing 31 along the inclination angle of the target plate 22. In addition, screw holes 51A and 52A are formed at two locations on the pressing plates 51 and 52, respectively, and the pressing plates 51 and 52 are connected to the housing through the through holes formed on the side surface of the housing 31. It is fixed by a screw inserted from the outside of the side surface of 31. Note that the screw through hole for fixing the presser plate 51 is a long hole, and the presser plate 51 can be slid along the longitudinal direction of the long hole by loosening the screw.

  As described above, the target plate 22 can be inserted and removed through the opening 31 </ b> C on the upper side of the housing 31. For example, when the target plate 22 is mounted, after the target plate 22 is inserted in a state where the screw for fixing the press plate 51 is loosened and the press plate 51 is slid to the front side, the press plate 51 is slid to the back side. Then, the target plate 22 is sandwiched between the pressing plates 51 and 52. And the target board 22 is fixed by tightening the screw which fixes the pressing board 51. FIG. Further, since the screw through-hole for fixing the presser plate 51 is a slanted long hole, the presser plate 51 can be placed in a state where the housing 31 is laid on the front side by loosening the screw fixing the presser plate 51. Slides toward the side of opening the target plate 22. Then, after the target plate 22 is replaced, the holding plate 51 is slid to the side where the target plate 22 is pressed by setting the housing 31 to be upright.

  The target plate 22 has sufficiently high durability and safety, for example, on the condition that a BB bullet having a diameter of 6 mm is used with a soft air gun for 18 years old or older. For example, under this condition, it was confirmed that even when the target plate 22 was shot with tens of thousands of BB bullets with a soft air gun, the target plate 22 was not damaged. By the way, even in this case, the target plate 22 does not become completely unusable, but the surface of the target plate 22 is gradually damaged or distorted, and the sharpness in visually recognizing the target behind is lost. In the target device 12, the target plate 22 can be exchanged, and the shooting environment can always be maintained in a good state. The dirt on the target plate 22 can be removed by wiping with a tissue wetted with water, more preferably with a tissue wetted with IPA (isopropyl alcohol) or ethanol.

  The reflection plate 34 is fixed by holding plates 53 and 54 that are fixed to the inside of the side surface of the housing 31. In FIG. 9, two pressing plates 53 and 54 arranged on the left side surface of the casing 31 are shown, but two pressing plates are similarly arranged on the right side surface of the casing 31. The

  The pressing plate 54 also has a function of pressing the reflecting plates 35 and 37. That is, the reflective plate 35 is adhered to the thin plate constituting the reflective plate 36 by the cushion material 43, the reflective plate 37 is adhered to the front wall portion of the housing 31 by the cushion material 44, and then the holding plate 54 is fixed. To do. Thereby, the end face of the pressing plate 54 presses the reflecting plate 35 against the thin plate and presses the reflecting plate 37 against the wall portion on the front side of the housing 31. After fixing the holding plate 54 in this way, the reflecting plate 34 is set on the left and right holding plates 54, and the reflecting plate 34 is fixed so as to be sandwiched between the holding plates 54 and 53.

  In addition, the reflecting plate 36 is fixed to the inside of both side surfaces of the housing 31 by using screw holes 36 </ b> C and 36 </ b> D formed in a portion where a part of the thin plate constituting the reflecting plate 36 is bent.

  By fixing the reflectors 35 and 37 using the cushion members 43 and 44, respectively, the energy of the BB bullets that bounce off the reflectors 35 and 37 can be efficiently attenuated. Further, the reflector 37 can further absorb the impact of the BB bullet by attaching only the vicinity of both left and right ends when viewed from the front with the cushion material 44 (see FIG. 2), and the rebound shown in FIG. BB bullets can be reflected at an angle.

  The holding plate 52 is bent so that a part near the upper end and a portion near the lower end are parallel to the target plate 22 in a state of being fixed to the target plate 22, and the bent portion is attached to the target plate 22. It becomes a fixing base 55 for fixing the impact sensor 23 to be fixed.

  A fixing structure for fixing the impact sensor 23 will be described with reference to FIG.

  As shown in FIG. 10, the impact sensor 23 includes a sensor portion 23 a and a printed board portion 23 b, and is sandwiched between cushion materials 56 and 57 and fixed between the target plate 22 and the fixing base 55. .

  For example, the cushion material 56 has strong adhesiveness on both sides, and strongly attaches the printed circuit board portion 23 b of the impact sensor 23 and the fixing base 55. In addition, the cushion material 57 disposed between the sensor unit 23 a and the target plate 22 has adhesiveness only on one side, and is adhered to the target plate 22. And the cushion material 57 will be in the state which presses the sensor part 23a by fixing the target board 22, and will transmit the vibration at the time of a BB bullet landing on the target board 22 to the sensor part 23a. Moreover, since the cushion material 57 becomes a structure which does not stick to the sensor part 23a, it can make the target board 22 replaceable as mentioned above.

  Thus, the impact sensor 23 is fixed so as to be pressed against the target plate 22 by the fixing base 55 from the back side. With such a fixing structure, the impact sensor 23 is prevented from falling off due to the impact force of the BB bullet landing on the target plate 22. For example, if the impact sensor 23 is simply attached to the target plate 22 with a cushioning material having strong adhesiveness on both sides, the impact sensor 23 may fall off due to the impact force of the BB bullet landing on the target plate 22. On the other hand, it was confirmed that with the fixing structure in which the fixing base 55 presses the impact sensor 23 against the target plate 22 from the back side, the impact sensor 23 does not fall off the target plate 22 even if tens of thousands of shots are performed.

  Further, by arranging the cushion materials 56 and 57 on both surfaces of the impact sensor 23, the impact force that the BB bullets land on the target plate 22 is absorbed by the cushion materials 56 and 57, and the impact force of the impact is the maximum of the impact sensor 23. Exceeding the rating is avoided.

  Here, the material of the target device 12 will be described.

  As described above, a polycarbonate plate having a thickness of 2 mm is used for the target plate 22 and the reflecting plates 34, 35, and 37. The impact strength of polycarbonate is about 200 times that of glass of the same thickness and 40 times that of acrylic of the same thickness. Usually, when a 2 mm thick acrylic board is shot using a 6 mm diameter BB bullet with a soft air gun having an energy of 0.09 J, the acrylic board may or may not break. From this, it is assumed that 0.09J is the limit for the ballistic performance of a BB bullet having a diameter of 6 mm on an acrylic plate having a thickness of 2 mm.

  Therefore, since the impact strength of the 2 mm thick polycarbonate plate used in the target device 12 is 40 times that of the acrylic plate of the same thickness, the limit of the 2 mm thick polycarbonate plate is in the case of a BB bullet having a diameter of 6 mm. This means 3.6J energy. On the other hand, the energy of the soft air gun permitted by Japanese law is up to 0.989 J in the case of a BB bullet with a diameter of 6 mm, so that the target plate 22 of the target device 12 has sufficient strength. Become.

  Furthermore, polycarbonate is about 1/3 to 1/4 the hardness of acrylic, and since polycarbonate has flexibility, it can absorb the energy of landing well. In addition, about the thickness of the polycarbonate board used for the target board 22, when it shoots with the soft air gun for 18 years old or more, in the polycarbonate board more than 3 mm in thickness, many BB bullets are cracked, and the thickness is 1 mm. In the polycarbonate plate, it was confirmed that a trace remained on the polycarbonate plate and the transparency was impaired. Therefore, the thickness of the target plate 22 using a polycarbonate plate is optimally 2 mm to 3 mm.

  Next, a method for using the target device 12 will be described.

  As shown in FIG. 1, the target device 12 is used in a state in which the target paper 21 is disposed on the back side and the monitor 14 is disposed at a location away from the target device 12. Hereinafter, such a usage method is referred to as a first usage method.

  And the 2nd and 3rd usage method demonstrated below is proposed for the target apparatus 12 besides the 1st usage method.

  FIG. 11 shows a target system 11 ′ according to the second method of use.

  In the second usage method, the target device 12 with the target paper 21 (FIG. 3) removed from the housing 31 is used, and the target device 12 is disposed on the front side of the monitor 14. Thereby, the user can perform shooting on the target image 25 displayed on the monitor 14 that is visually recognized through the transparent target plate 22 and the back plate 32.

  For example, the user operates the target application software executed by the personal computer 13 to set the specification and resolution of the monitor 14, thereby causing the target image 25 displayed on the monitor 14 to be the target of the target device 12. It is made to correspond to the size of the surface (for example, the size of the target drawn on the target paper 21 in FIG. 1). Then, the user matches the outer frame of the target image 25 with the inner frame of the target surface of the target device 12 by adjusting the display position of the target image 25.

  By displaying the target image 25 on the monitor 14 in this manner, the user can perform shooting while targeting the target image 25 as in the case where the target paper 21 in FIG. 1 is targeted.

  In the target system 11 ′, the personal computer 13 executes the shooting application software, so that the BB bullets are applied to the target plate 22 based on the impact detected by the impact sensors 23-1 to 23-4. The landed landing position can be detected, and a landing mark can be displayed at a location corresponding to the landing position of the target image 25 displayed on the monitor 14. Thus, by displaying the landing mark on the target image 25 corresponding to the landing position where the BB bullet landed on the target plate 22, the user can experience a more realistic and realistic shooting. . Further, by displaying the landing mark on the target image 25 of the monitor 14, the user can naturally perform the next aiming correction without taking his eyes off the monitor 14.

  Note that by storing the display position of the target image 25 in the personal computer 13, the target image 25 can be displayed at the same position each time the shooting application software is executed. Thus, if the position of the target device 12 with respect to the monitor 14 is not changed, shooting can be started without adjusting the display position of the target image 25 when the shooting application software is executed.

  Further, when the target device 12 is used in the second usage method, the back plate 32 is expanded so as to be a size capable of protecting the monitor 14 as described above, or on the front surface so as to cover the monitor 14. A transparent protective plate 61 is attached. As the transparent protective plate 61, a polycarbonate plate processed so as to be easily mounted on the monitor 14 is used.

  For example, as shown in FIG. 12, the transparent protective plate 61 has a bent portion 62 formed on the upper side and a rubber plate 63 attached to the inside of the bent portion 62. The transparent protective plate 61 is attached to the monitor 14 so that the bent portion 62 is hung on the upper surface of the monitor 14, and the rubber plate 63 functions as a slip stopper. In addition, screw holes 64 to 67 are formed in the vicinity of the left and right ends of the transparent protective plate 61, and expansion plates (not shown) are formed on the left and right sides of the transparent protective plate 61 using the screw holes 64 to 67. ) Can be used for wide-screen monitors.

  Instead of attaching the protective plate 61 to the monitor 14 or protecting the back plate 32 by expanding it, the target device 12 is so sized that the target device 12 covers the entire surface of the monitor 14. You may design the size of For example, a recent large-screen television receiver can be used as a monitor for a personal computer. Therefore, the target device 12 is designed to have a size corresponding to a large-screen television receiver and is installed in front of the large-screen television receiver, so that it is more realistic and realistic without using the protective plate 61. There is a feeling, you can let you experience shooting with high game characteristics. For example, when the target device 12 is applied to a horizontally wide screen, six impact sensors 23 are used by adding two impact sensors 23 above and below the center of the screen in addition to the four corners of the screen. The impact position measurement accuracy can be improved by calculating the impact position using the shock wave signals detected by the three or four impact sensors 23 close to the impact position among the impact sensors 23. it can.

  Depending on the material and size of the target plate 22, an acoustic sensor that detects sound generated by the shock wave can be used as a detection unit that detects the shock wave, instead of the shock sensor 23. When using an acoustic sensor, for example, the sensor unit 23a in FIG. 10 is replaced with a sensor unit having a function of detecting sound, and the cushion 57 is omitted, so that the sensor unit 23a is positioned slightly away from the target plate 22. An acoustic sensor can be held. As described above, in the target device 12, the impact sensor 23 is directly fixed to the target plate 22, and an acoustic sensor is fixed in the vicinity of the target plate 22.

  Next, FIGS. 13 and 14 show a target system 11 ″ according to the third usage method.

  In the third usage method, the target device 12 with the target paper 21 and the back plate 32 (FIG. 3) removed from the housing 31 is used, and the sub monitor 71 is mounted on the back surface of the target device 12. The sub-monitor 71 is connected to the personal computer 13 via the monitor cable 16a and displays a target image 25 'linked to the target image 25 displayed on the monitor 14. As a result, the user can perform shooting by targeting the target image 25 ′ displayed on the sub-monitor 71 that is visually recognized through the transparent target plate 22.

  Further, as shown in FIGS. 13 and 14, the target device 12 can be used while being fixed to the tripod 72. When using the tripod 72, the target device 12 is attached to the tripod 72 using the nut 42 (FIG. 3) fixed inside the target device 12.

  The sub monitor 71 is attached to the target device 12 using an attachment plate 73 fixed to the back side of the target device 12.

  As shown in FIG. 15, the mounting plate 73 is formed of a transparent polycarbonate plate, and a bent portion 74 is formed in the central portion of the upper side, and a bent portion 75 is formed in the central portion of the lower side. On the inner side, a cushion material 76 is attached so that the sub monitor 71 is not damaged even if the BB bullet hits the mounting plate 73. A fixed stopper 77 is disposed near the left side of the mounting plate 73, and a detachable stopper 78 is disposed near the right side of the mounting plate 73.

  For example, with the detachable stopper 78 removed, the sub-monitor 71 is inserted between the bent portions 74 and 75 and brought into contact with the fixed stopper 77, and the detachable stopper 78 is attached. A sub-monitor 71 is attached to. Thus, by using the fixed stopper 77, the position in the left-right direction when the sub monitor 71 is attached to the mounting plate 73 can be defined. A cushion material 79 is attached to the surface of the detachable stopper 78 that contacts the sub monitor 71. In addition, as a structure which mounts the sub monitor 71 to the target apparatus 12, it is not limited to the structure which uses the attachment plate 73 as shown in FIG. 15, Various structures can be employ | adopted.

  When the sub monitor 71 is attached to the target device 12 in this way and the user operates the application software for shooting executed by the personal computer 13 to display the target image 25 ′ on the sub monitor 71, the sub monitor 71. The target image 25 ′ is displayed on the screen. Further, when the user operates to display the target image 25 ′ on the full screen, the target image 25 ′ is displayed on the sub monitor 71 on the full screen.

  By displaying the target image 25 ′ on the sub-monitor 71 in this way, the user can perform shooting with the target image 25 ′ as a target in the same manner as when the target paper 21 in FIG. 1 is targeted. Further, in the target system 11 ″, similarly to the target system 11 ′ described with reference to FIG. 11, the landing mark is displayed on the target image 25 ′ corresponding to the landing position where the BB bullet has landed on the target plate 22. The user can experience a more realistic and realistic shooting.

  In the third usage method, not only the target image 25 ′ is displayed on the sub monitor 71 but also the target image 25 is displayed on the monitor 14, and various setting screens (FIG. 16 described later) are displayed on the monitor 14. Browse) is displayed. Therefore, even if the target device 12 is located far away, the user can easily check landing and make various settings by placing the monitor 14 close.

  The personal computer 13 stores a setting for displaying the target image 25 ′ on the sub monitor 71 on the full screen, so that the target image 25 ′ is displayed on the sub monitor 71 on the full screen simply by executing the shooting application software. Can be displayed.

  Furthermore, in the third usage method, a tablet computer having a display can be used instead of the sub monitor 71. When a tablet computer is used, it is necessary to connect the tablet computer to the target device 12. Further, although it is not necessary to connect to the personal computer 13, it becomes impossible to perform a touch operation on the tablet computer. Therefore, for example, operation means for operating shooting application software executed on a tablet computer via an interface such as a wireless LAN (for example, another personal computer, a tablet computer, a smartphone, etc. ) Must be used.

  Next, FIG. 16 shows a main screen displayed on the monitor 14 when the personal computer 13 executes the shooting application software.

  For example, when the target device 12 is connected to the personal computer 13 via the communication cable 15 and the personal computer 13 executes shooting application software, the main screen 81 is displayed on the monitor 14. The target device 12 operates with power supplied from the personal computer 13 via the communication cable 15. However, when the communication cable 15 is extended, power is supplied to the target device 12 from another power source. May be.

  In addition to the target image 25, the main screen 81 displays a competition setting input unit 82, a start button 83, a reset button 84, a display setting input unit 85, a countdown timer 86, a competition result display unit 87, and a data display unit 88. . Note that it is not necessary to display all these parts on the main screen 81, and it is possible to set so that only a part is displayed.

  The competition setting input unit 82 is an interface (for example, a drop-down list) for inputting various settings necessary for performing a shooting competition such as shooting mode, number of bullets, holding time, and scoring. Is displayed. In the display example of FIG. 16, “real shooting” is set as the shooting mode, “5 shots” is set as the number of competition bullets, “2 minutes 30 seconds in total” is set as the holding time, and “ The outer circumference of the bullet is set.

  In the shooting mode of the competition setting input unit 82, “trial shooting” or “main shooting” is selected. When “main shooting” is selected in the shooting mode, a start button 83, a reset button 84, and a countdown timer 86 are selected. The competition result display section 87 is displayed. On the other hand, when “trial shooting” is selected in the shooting mode, the start button 83, the reset button 84, the countdown timer 86, and the competition result display section 87 are not displayed.

  In the number of competition bullets in the competition setting input unit 82, the number of bullets of the BB bullets at which the shooting competition (game) ends is set.

  In the holding time of the competition setting input section 82, “all” or “every shot” is selected, and if “all” is selected as the holding time, the number of bullets set in the number of competition bullets is all Time is set. Further, when “every shot” is selected as the holding time, the holding time for each BB bullet is set. If “every time” is selected as the time, the minutes cannot be set, only the seconds (up to 99 seconds) are set, and the countdown timer 86 has only seconds. Is displayed.

  In the scoring judgment of the competition setting input unit 82, the “center of bullet” or the “periphery of the bullet” is selected, and when the “center of bullet” is selected in the scoring judgment, when the BB bullet hits, A score is determined at the center. In addition, when “outer circumference of bullet” is selected in the score determination, when the BB bullet hits, if the outer circumference of the BB bullet touches the inner ring of the target even a little, it is determined to be the score of the inner ring. The In the personal computer 13, the center of the BB bullet is obtained as the landing position, but the score is determined on the outer circumference of the BB bullet by performing a calculation for shifting the landing position to the inside of the target by the radius from the center of the BB bullet. can do.

  The start button 83 is displayed when “real shooting” is selected in the shooting mode of the game setting input unit 82, and the shooting game is started by operating the start button 83. It is also possible to set the shooting competition to be started when the first landing is detected.

  The reset button 84 is displayed when “actual shooting” is selected in the shooting mode of the competition setting input unit 82, and by operating the reset button 84, the competition result is cleared and the initial state is restored. In addition, if the game is in progress, the shooting competition is interrupted and the initial state is restored.

  The display setting input unit 85 displays an interface (for example, a check box or a button) for inputting settings related to the landing mark displayed on the target image 25. In the display example of FIG. 16, a check box for setting whether or not to leave an old bullet hole, a check box for setting whether or not to flash a bullet hole, and a button that is operated when deleting the bullet hole are displayed.

  When the check box for setting whether or not to leave an old bullet hole in the display setting input unit 85 is set to leave an old bullet hole (checked), the color of the old bullet mark other than the latest bullet mark is changed (for example, , Changed to gray) and the landing mark remains displayed. On the other hand, if it is set not to leave an old bullet hole (unchecked), only the latest landing mark is displayed. Furthermore, a number indicating the order of shooting can be displayed for the landing mark.

  If the bullet setting is set to be blinked (checked) by the check box for setting whether or not the bullet hole of the display setting input unit 85 is blinked, the latest landing mark is blinked and displayed. On the other hand, if it is set not to blink bullet holes (unchecked), the landing mark will not blink. By blinking the landing mark, the visibility of the landing mark from the middle distance or long distance can be improved, and the latest landing mark and the old landing mark can be easily distinguished. In particular, when shooting from a position several meters away, it is possible to more effectively determine the landing mark.

  When the shooting competition starts, the countdown timer 86 counts down from the time set by the holding time of the competition setting input unit 82 and displays the remaining time. When “all” is selected in the holding time of the competition setting input section 82, the countdown timer 86 displays the remaining time in the format of “minute: second”, and the shooting competition ends when the time is up. In addition, when “every shot” is selected in the holding time of the competition setting input unit 82, the countdown timer 86 displays only “seconds”, and when the time is up without landing, the score of the shot is 0 point. It is said that it advances to the next shot.

  The competition result display section 87 is displayed when “real shooting” is selected in the shooting mode of the competition setting input section 82, and the number of lines in the competition result display section 87 is the number of competition bullets in the competition setting input section 82. Depending on the number of bullets set. In the display example of FIG. 16, since the number of competition bullets in the competition setting input unit 82 is set to 5 shots, 1 to 5 rows are prepared as shots, and each row has a score in each shot. (Score) and Time are displayed, and the total score and time are displayed in the last line.

  Further, in the time of the competition result display section 87, when “all” is selected in the holding time of the competition setting input section 82, the time after the start of the shooting competition is displayed for each landing. In addition, in the time of the competition result display section 87, when “every shot” is selected in the holding time of the competition setting input section 82, the time count is started for each landing, and the count is started. The time until landing is displayed. The total score in the competition result display section 87 is recalculated and displayed for each landing.

  In the data display section 88, the diameter and weight of the BB bullets used for shooting, the energy (J) generated by the landing, the bullet velocity (m / second), the number of cycles (1) is the number of bullets per second ( Is displayed. In the display example of FIG. 16, “6 mm / 0.2 g” is displayed for the bullet diameter / bulk weight, “0.437” is displayed for the energy, “66.10” is displayed for the bullet velocity, and the number of cycles is blank. .

  In the bullet diameter and bullet weight of the data display section 88, set values of the diameter and weight of the BB bullet used for shooting are inputted and displayed. In the shooting application software executed by the personal computer 13, the set value set in the data display unit 88 is used, and the energy and velocity are calculated based on the impact force upon landing. The setting values input to the bullet diameter and bullet weight of the data display unit 88 are recorded in the personal computer 13 and when the shooting application software is executed, the recorded setting values are read and displayed. Is done.

  The energy at the time of landing is displayed as the energy of the data display section 88, and the bullet speed at the time of landing is displayed as the bullet speed. The number of cycles in the data display area 88 indicates how many shots have been landed in 1 second. Actually, the measurement was started when there were 2 landings in 0.5 seconds, and the landing was interrupted for 0.5 seconds. At that point, the maximum number of cycles from the start to the point of interruption is displayed.

  Such a main screen 81 is displayed on the monitor 14 and a shooting competition is performed.

  FIG. 17 shows a target image 25 ′ displayed on the sub monitor 71.

  A target similar to the target image 25 of the monitor 14 is displayed on the target image 25 ′ of the sub monitor 71. In the display example of FIG. 17, ten rings are displayed as targets, and scores (1, 2, 3,..., 8 in order from the outside) are displayed between the respective rings. In addition, in the target image 25 ′, the shot value is displayed in the upper left corner, the latest score value is displayed in the lower left corner, and the total score value is displayed in the lower right corner in synchronization with the data display section 88 of FIG. 16. In the target image 25 ′, the countdown value is displayed on the upper right in synchronization with the countdown timer 86. Further, when a BB bullet hits the target plate 22, a landing mark corresponding to the landing position is displayed in the target image 25 ′.

  Thus, since information such as shots, scores, and times is displayed on the sub monitor 71 and the landing position is displayed on the target image 25 ′, the user can check the information without taking his eyes off the sub monitor 71. And the landing position can be confirmed, and the next aiming correction can be naturally performed.

  FIG. 18 is a diagram illustrating a modification of the target device.

  The target device 12 ′ shown in FIG. 18 includes a target reflector 91 instead of the target plate 22 and the reflectors 34 to 37 provided in the target device 12 of FIGS. 2 and 3. In the target device 12 ′, the arrangement of the signal processing unit 24, the communication terminal 39, and the LED 40 is also different from that of the target device 12 in FIGS. 2 and 3.

  The target reflection plate 91 of the target device 12 ′ is produced by subjecting one flat plate of polycarbonate to heat bending at a plurality of locations, and the flat portions 92 to 92 corresponding to the target plate 22 and the reflection plates 34 to 37, respectively. 96.

  That is, in the target reflector 91, the flat portion 92 has an inclination angle of 68 ° with respect to the wall portion on the upper surface of the housing 31, similarly to the target plate 22, and the flat portion 93 has the same angle as the reflector 34. It is formed to have an inclination angle of 68 ° with respect to the wall portion on the front side of the housing 31. Therefore, in the target reflecting plate 91, the flat surface portion 92 and the flat surface portion 93 are formed so that the interval is narrowed from the front side of the target device 12 ′ toward the lower side of the back surface similarly to the target plate 22 and the reflecting plate 34. The As a result, in the target device 12 ′, the BB bullets are guided to the entrance of the accommodation area while being bounced back between the flat surface portion 92 and the flat surface portion 93, so that the BB bullets can be reliably accommodated.

  Further, the target reflector 91 is formed by appropriately adjusting the inclination angles of the flat portions 94 and 96 so that the BB bullets bounce back at the same reflection angles as the reflectors 35 and 37, respectively. However, since the reflecting plate 95 is not an iron plate like the reflecting plate 36, the reflecting angle is different from that of the reflecting plate 36, and here, it is formed at an angle that reflects slightly downward.

  Thus, in the target device 12 ′, since one target reflector 91 has a function equivalent to that of the target plate 22 and the reflectors 34 to 37, the target device 12 ′ is more effective than the target device 12 shown in FIGS. The structure can be simplified.

  Furthermore, in order to reduce the cost by mass production, it is important that the target device 12 'can be manufactured from a material that is inexpensive and easy to mold. Therefore, you may design so that the target reflector 91 may be divided | segmented in the A part, B part, and C part which are instruct | indicated with the arrow in FIG. With such a design, the target plate corresponding to the flat surface portion 92 can be inserted and removed from the upper surface of the target device 12 ', the reflective plate corresponding to the flat surface portion 93 can be inserted and removed from the front of the target device 12', and the BB bullet is vertical. It is possible to open and close the reflecting plate corresponding to the flat portion 96 that is highly likely to collide with the flat plate 96.

  Thereby, the target plate corresponding to the flat surface portion 92 can be exchanged, the reflector corresponding to the flat surface portion 93 is removed, the signal processing unit 24 is easily maintained, and the target device 12 ′ can be BBed from the front surface. By removing the bullet, the drawer 38 (FIG. 3) becomes unnecessary. Furthermore, since the energy of the BB bullet is attenuated to about 1/3 each time it is reflected, the strength of the portion excluding the parts corresponding to the plane portions 92, 93 and 96 is sufficient to be 1/27. Easy materials can be used. As a result, if only the parts corresponding to the flat portions 92, 93 and 96 are made of a material having high strength such as polycarbonate, the entire casing 31 including other reflectors is a general material and is inexpensive by injection molding or the like. Can be mass-produced and the cost can be greatly reduced.

  Further, the target device 12 ′ is designed to divide the flat surface portion 92 at a D portion indicated by an arrow in FIG. 18, and the impact sensors 23-1 to 23-4 are attached to the divided upper portions. You may do it. Similarly, also in the target apparatus 12, the target plate 22 is designed to be divided at a position corresponding to the D portion indicated by the arrow in FIG. 18 (a position slightly lower than the front end portion of the reflecting plate 34). can do. That is, the target plate 22 is not limited to being configured by a single plate, but can be configured such that a plurality of plates are continuously arranged.

  By adopting such a configuration, the structure around the part to which the impact sensors 23-1 to 23-4 are attached (for example, the distance from the corner) can be made the same structure, respectively. The influence of the structure on the detection values of the impact sensors 23-1 to 23-4 is made uniform, and the landing position can be detected stably. Further, when the target plate 22 is damaged, the target plate 22 can be partially exchanged, and the area to be exchanged can be reduced in area.

  In the description of FIG. 3, the interval D between the inlets 101 of the accommodation region 102 is 10 mm. However, the interval D is not limited to 10 mm and may be appropriately changed depending on the diameter of the BB bullet used. . For example, when the distance D was set to 10 mm and a BB bullet having a diameter of 6 mm or 8 mm was used, the BB bullet could be recovered well. For example, even when the distance D was set to 7 mm and a BB bullet having a diameter of 8 mm was used, it was confirmed that the BB bullet spreads the target plate 22 or the reflecting plate 34 and enters the accommodation region 102.

  Further, in the conventional target device, the target paper is consumed because the target paper is perforated. On the other hand, the target device 12 does not consume the target paper, so that it is resource-saving and economical. It is.

  Further, the target device 12 can be applied to many ways of playing by changing application software executed by the personal computer 13. For example, the target device 12 is designed so as to correspond to a large-screen television receiver, and application software that shoots a moving target on a game screen displayed on the large-screen television receiver and competes for a score. Also, the target device 12 can be made to correspond.

  Furthermore, in the target system 11, the landing position can be accurately measured, and the landing position can be measured with a resolution within 1 mm at the center of the target plate 22 (the portion excluding the outermost part of the target plate 22). It was. Further, the target system 11 can measure the bullet velocity of the bullet based on the measurement of impact force due to landing. On the other hand, a general grenade will no longer be used after measurement. Accordingly, the target system 11 is a single device that is used on a daily basis, and can have a function of collecting a bullet, a function as a target device, and a function of measuring a bullet velocity, compared with a conventional target device. Is very advantageous. Also, in general, many grenades measure the transit time of bullets between two points in the pipe, so in addition to having to shoot with the muzzle very close to the pipe, Only the initial velocity of the bullet could be measured. On the other hand, in the target system 11, if the bullet hits the target plate 22 of the target device 12, the bullet velocity can be measured. Therefore, the target system 11 can also measure the attenuation of the bullet velocity with respect to the distance. It has great versatility.

  In the target system 11, in addition to displaying the target on the entire target image 25 on the monitor 14 or the sub monitor 71, for example, a small target whose size can be changed to a predetermined size is displayed on the target image 25. be able to. In the target system 11, a plurality of small targets are displayed on the monitor 14 or the sub monitor 71 at the same time, and the small target is shot within a specified time, or a plurality of small targets are shot. A usage method for displaying and shooting at random, sequentially, a usage method for displaying and shooting a small target so as to move around while bouncing off at the end of the target image 25, and a small target that moves for a set time at a random position. A usage method for displaying and shooting can be used.

  In the target system 11, quietness can be improved by attaching a plate made of a material softer than the target plate 22 to the surface of the target plate 22. As described above, when polycarbonate is used as the target plate 22, for example, by setting the surface of the target plate 22 with a soft vinyl chloride plate having a thickness of 2 mm, the sound energy is reduced to about ¼. Can be reduced. At this time, the reflection angle of the BB bullet is substantially the same as that of the polycarbonate alone, and a sufficient ability can be exhibited for the recovery of the BB bullet. In addition, when it is set as the structure which stuck the vinyl chloride board on the surface of the target board 22, since the detected value of the impact sensors 23-1 to 23-4 becomes 1/4 or less, the impact sensors 23-1 to 23-4. It is necessary to appropriately correct the amplification degree of the output.

  Furthermore, the direct hit of a BB bullet fired from an air gun for 18 years old or more is powerful enough to dent a 0.8 mm iron plate, and the impact sensor 23 arranged behind the target plate 22 may be destroyed. Therefore, it is necessary to take measures to prevent the impact sensor 23 from being destroyed. As a countermeasure against this, for example, a countermeasure method for attaching a protective plate made of polycarbonate with a spacer or cushion slightly lifted is effective. Further, such a countermeasure method has a safety effect of attenuating the energy of the BB bullet even when the BB bullet bounces back to the shooter.

  Moreover, in the target apparatus 12, the protective plate for avoiding a BB bullet hitting directly to the housing | casing vertical part under the opening part 31A of a front side, and the attachment location of the impact sensors 23-3 and 23-4 is provided. A protective plate is attached to the front surface of the casing 31 or to the surface side of the target plate 22 corresponding to the mounting location of the impact sensors 23-1 and 23-2 via a cushion material having adhesiveness on both sides. Or you may. As shown in FIGS. 2 and 3, the target device 12 is formed with bent portions 45a to 45c so as to surround the edge of the opening 31A in a U-shape. The strength is improved, and the BB bullet hitting the edge of the opening 31A is easily rebounded inside the housing 31. By taking such measures, the target device 12 will never be damaged no matter where it hits from the front of the target device 12, and the bullet will not rebound strongly to the shooter. The safety when using the target device 12 can be further enhanced.

  Further, the shooting application software executed in the target system 11 can be controlled via a network. Thus, for example, when controlling from a smartphone, the target system 11 performs operations such as “start”, “save”, and “reset” by voice recognition when executing the shooting application software. Can be done. Here, “save” means “save the shooting results”.

  In the present embodiment, the configuration in which a transparent material such as polycarbonate is used as the target plate 22 to make the target paper 21 visible is described. However, for example, the target is drawn on the target plate 22 itself. In some cases, the target system 11 may employ a target plate 22 using an opaque material. In other words, the target system 11 is limited to the transparent target plate 22 as long as the BB bullet can be accommodated after the BB bullet is repeatedly reflected between the target plate 22 and the reflection plate 34 having the inclination angle as described above. Is not to be done.

  Furthermore, the target system 11 can be configured to include a display unit capable of displaying the target image 25 at a position behind the target plate 22 in the housing 31, thereby connecting to the personal computer 13. The target device 12 can be used alone.

  In the present specification, the term “system” represents the entire apparatus constituted by a plurality of apparatuses. The embodiments of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
