<Example of target system configuration>

As shown in FIG. 1, the target system 10 is composed of a target device 11, a display 12, and a PC (Personal Computer) 13, and the display 12 is arranged on the back side of the target device 11. Although the notebook type PC 13 is shown in FIG. 1, a tablet type PC or the like can also be used.

For example, the user installs the PC 13 at hand, connects the target device 11 and the PC 13 with the signal cable 14, and connects the display 12 and the PC 13 with the video cable 15. In addition, wireless communication may be used instead of the signal cable 14 and the video cable 15, and for example, the target device 11 and the PC 13 may be configured to be connected by wireless communication. Then, the user operates the PC 13 to display the target image 16 representing the target at the time of shooting on the display 12.

After that, the user points the barrel of the soft air gun 17 toward the target device 11, looks into the sighting device fixed along the barrel, aims at the target image 16 displayed on the display 12, and shoots. You can do the target. The BB bullet 18 fired from the soft air gun 17 absorbs the momentum of collision by bending the target plate 23 (see FIGS. 2 to 4) of the target device 11. Then, the BB bullet 18 that has landed on the target plate 23 of the target device 11 falls on the collection mat 19 arranged below the front side of the target device 11 and is collected without being scattered.

Here, the collection mat 19 has a low resilience (slowly) so as to absorb the impact of the fall of the BB bullet 18 and the BB bullet 18 does not bounce off, for example, like a bore cloth or a pile cloth. It is preferable to use one having the property of returning to the original shape). For example, by using a collection mat 19 having soft protrusions such as hair or unevenness on the surface, the BB bullets 18 that have fallen on the collection mat 19 are prevented from rolling, and the BB bullets 18 are more reliably scattered. Can be prevented. Further, when collecting the BB bullets 18 scattered on the collection mat 19, for example, by lifting both ends of the collection mat 19 and narrowing it back and forth, the BB bullets 18 are placed in the center of the collection mat 19. It can be gathered and easily collected. More preferably, it was confirmed that the BB bullets 18 can be completely recovered without being scattered by using a thick so-called microfiber towel folded in half.

Further, when a bag-shaped collection mat 19 having a size capable of accommodating the target device 11 rolled into a roll shape is adopted as described later, for example, when the target device 11 is transported, the collection mat 19 is used. The target device 11 can be protected. Of course, the collection mat 19 is not limited to the bag-shaped one. The target system 10 may use a box-shaped collection tray 20 (see FIG. 6 described later), for example, as long as the BB bullets 18 can be collected without being scattered.

Then, the target system 10 can detect the landing position where the BB bullet 18 has landed on the target device 11, and the landing mark P indicating the landing position is superimposed on the target image 16 displayed on the display 12. Will be done. Then, in the target system 10, the target image 16 similar to the display 12 is displayed on the display unit of the PC 13, and the user can use the landing mark P displayed on the display unit of the PC 13 to display the landing position of the BB bullet 18. Can be confirmed in detail.

The target system 10 is configured in this way, and can be used in a competition in which the target image 16 displayed on the display 12 is targeted and the accuracy of the landing position is competed. In addition, there is a need to improve the sense of presence by using a display 12 with a larger screen size, and it is important to have a configuration that is easy to handle such as portability and storability even if the target device 11 is enlarged. It has become.

<First configuration example of the target device>

The target device 11 of the first configuration example will be described with reference to FIGS. 2 to 4. FIG. 2 shows a front view of the target device 11, FIG. 3 shows a plan view of the target device 11, and FIG. 4 shows a side view of the target device 11. ..

As shown in the figure, the target device 11 includes an upper side fixing member 21, a lower side fixing member 22, a target plate 23, a back plate 24, side support members 25 and 26, acoustic sensors 27-1 to 27-4, and a control unit. 28 is provided.

As shown in FIG. 4, the upper side fixing member 21 is, for example, a member having a U-shaped cross section and having substantially the same length as the width of the target plate 23 and the back plate 24. Further, the upper side fixing member 21 has an elongated shape along the upper sides of the target plate 23 and the back plate 24, and a plurality of screws are used with respect to the upper sides of the target plate 23 and the back plate 24 at predetermined pitch intervals. It is fixed. Of course, the target plate 23 and the back plate 24 may be fixed to the upper side fixing member 21 by a fixing method other than screws. For example, the upper end portions of the target plate 23 and the back plate 24 are fixed to the upper side by a member on the elongated plate. A fixing method such as sandwiching the member 21 may be adopted.

The lower side fixing member 22 has the same shape as the upper side fixing member 21, and is fixed to the lower side of the target plate 23 and the back side plate 24.

The target plate 23 is a transparent member that transmits the target image 16 displayed on the display 12, and can be received by bending the collision of the BB bullet 18 fired by the soft air gun toward the target image 16. A soft sheet-like member is used. For example, for the target plate 23, it is preferable to use a soft vinyl chloride resin having a thickness of 1.5 mm or the like as a material having a slow restoration rate against deformation due to impact. Further, the target plate 23 has an upper side of the upper side fixing member 21 so as to be flat as a whole in a state of being stretched so as to be substantially vertical in front of the display 12, that is, to be flat so as not to cause bending. It is fixed to the side surface on the front side, and the lower side is fixed to the side surface on the front side of the lower side fixing member 22.

The back plate 24 is made of a transparent and soft sheet-like member similar to the target plate 23, for example, a soft vinyl chloride resin having a thickness of 1.5 mm, and the back side of the target plate 23 (display 12 side when viewed from the user). ) Is placed. That is, the back plate 24 is planarly fixed to the side surface on the back side of the upper side fixing member 21 and the lower side is fixed to the side surface on the back side of the lower side fixing member 22 in a plane similar to the target plate 23.

In this way, the target plate 23 is fixed to the front side surface of the upper side fixing member 21 and the lower side fixing member 22, and the back plate 24 is fixed to the back side side surface of the upper side fixing member 21 and the lower side fixing member 22. .. As a result, between the target plate 23 and the back plate 24, there is a space D as shown in FIGS. 3 and 4, depending on the width of the upper surface of the upper side fixing member 21 and the width of the lower surface of the lower side fixing member 22. 29 is provided.

The side support members 25 and 26 are rod-shaped members (so-called shredded bolts) having screws formed on the side surfaces over the entire length, and are formed so as to be slightly longer than the vertical width of the target plate 23 and the back plate 24. Will be done. As shown in FIG. 2, when the target device 11 is viewed from the front, the side support member 25 supports the left end portion of the upper side fixing member 21 and the lower side fixing member 22, and the side support member 26 is the upper side fixing member 21. And supports the right end of the lower side fixing member 22.

Further, the side support member 25 is easily and detachably attached to the upper side fixing member 21 and the lower side fixing member 22 by using the nuts 31 to 34. Similarly, the side support member 26 is easily and detachably attached to the upper side fixing member 21 and the lower side fixing member 22 by using the nuts 35 to 38.

Specifically, the nut 31 and the nut 32 are screwed into the screw on the upper part of the side support member 25 so as to sandwich the vicinity of the left end portion of the upper side fixing member 21, and the lower part of the side support member 25. The nut 33 and the nut 34 are screwed into the screw so as to sandwich the vicinity of the left end portion of the lower side fixing member 22. Similarly, the nut 35 and the nut 36 are screwed into the screw on the upper part of the side support member 26 so as to sandwich the vicinity of the right end portion of the upper side fixing member 21, and also on the screw on the lower part of the side support member 26. The nut 37 and the nut 38 are screwed so as to sandwich the vicinity of the right end portion of the lower side fixing member 22. As a result, both ends of the upper side fixing member 21 and the lower side fixing member 22 are supported. For example, by using nuts (so-called high nuts) having a certain length as nuts 32, 33, nuts 36, and nuts 37, the lengths can be easily picked up by fingers, so that no tools are used. Can be easily rotated.

The acoustic sensors 27-1 to 27-4 acquire, for example, the impact sound generated when the BB bullet 18 lands on the target plate 23, and the acoustic signal according to the change in the amplitude of the acquired impact sound is transmitted to the control unit 28. Supply.

Regarding the arrangement of the acoustic sensors 27-1 to 27-4, the space sandwiched between the target plate 23 and the back plate 24 so as to be on the back side of the target plate 23 and close to the four corners of the target plate 23, respectively. It is fixed in 29. For example, the acoustic sensor 27-1 is arranged near the left end of the surface facing the lower side of the upper side fixing member 21, and the acoustic sensor 27-2 is arranged near the right end of the surface facing the lower side of the upper side fixing member 21. .. Further, the acoustic sensor 27-3 is arranged near the left end of the surface facing the upper side of the lower side fixing member 22, and the acoustic sensor 27-4 is arranged near the right end of the surface facing the upper side of the lower side fixing member 22. In the following, when it is not necessary to distinguish each of the acoustic sensors 27-1 to 27-4 as appropriate, it is simply referred to as an acoustic sensor 27.

In this way, the acoustic sensor 27 is arranged in the space 29 sandwiched between the target plate 23 and the back plate 24 fixed in parallel at the interval D, and the impact sound resonates between the target plate 23 and the back plate 24. By doing so, a stable acoustic signal can be obtained.

Although the configuration using the four acoustic sensors 27-1 to 27-4 will be described in the present embodiment, the number of the acoustic sensors 27 is not limited to four. For example, it is possible to use a number of acoustic sensors 27 such as 3, 6, and 8 that can appropriately measure the landing position and the like according to the size or shape of the target device 11. For example, when six acoustic sensors 27 are used, the acoustic sensors 27 are arranged not only at the four corners but also at the center of the upper side and the center of the lower side.

The control unit 28 is attached to a main fixing plate 41 fixed to the center of the upper side surface of the upper side fixing member 21, and is a signal for inputting an acoustic signal output from the acoustic sensors 27-1 to 27-4. Lines (not shown) are connected.

For example, the control unit 28 houses a signal processing board that performs predetermined signal processing on the acoustic signals output from the acoustic sensors 27-1 to 27-4 when the BB bullet 18 lands on the target plate 23. To. This signal processing board is a detection signal for detecting the landing position, landing speed, etc. when the BB bullet 18 lands on the target plate 23 based on the acoustic signals output from the acoustic sensors 27-1 to 27-4. Is output. For example, in a predetermined signal processing by a signal processing board, a peak hold signal obtained by amplifying an acoustic signal and performing full-wave rectification and holding the peak value of the amplitude, and a signal obtained by integrating the peak hold signal are reference values. The impact sound detection time signal indicating the above timing is output as a detection signal.

Further, as shown in FIG. 4, on the side surface of the control unit 28, a connector 52 for connecting the signal cable 14 of FIG. 1 and a power supply indicator LED indicating that power is supplied to the control unit 28 ( Light Emitting Diode) 53 is provided. Then, the detection signal output from the signal processing board housed in the control unit 28 is supplied to the PC 13 of FIG. 1 via the signal cable 14.

Here, as shown in FIG. 4, the main fixing plate 41 is fixed so as to project from the upper side fixing member 21 to the back surface side, and the cushioning rubber plate 51 is mounted on the surface facing the lower side of the projecting portion. Is pasted. Then, by putting the cushioning rubber plate 51 in close contact with the upper surface of the display 12, the target device 11 can be attached to the display 12. At this time, spacers 71 to 74 are attached to the four corners (see FIG. 2) of the outer frame of the display 12 in order to provide a slight gap between the back plate 24 of the target device 11 and the surface of the display 12. .. In the target device 11, the thickness (number of sheets) of the cushioning rubber plate 51 is appropriately selected according to, for example, the frame width of the upper side of the display 12 to be used, and the target plate covers the display area of the display 12. The 23 and the back plate 24 can be adjusted to be arranged. Instead of the cushioning rubber plate 51, a lightweight foamed resin or the like may be used for cushioning. Further, the display position of the target image 16 displayed on the display 12 can be finely adjusted.

Further, as shown in FIG. 3, the auxiliary fixing plate 42 is attached near the left end of the upper side surface of the upper side fixing member 21, and the auxiliary fixing plate 43 is attached near the right end of the upper side surface of the upper side fixing member 21. The auxiliary fixing plates 42 and 43 are screwed to the upper side fixing member 21, are rotatable in a loosened state, and are attached so as to be fixed in a tightened state.

The target device 11 is configured in this way, and when mounted on the display 12, the upper side fixing member 21 is arranged at a predetermined position along the upper side of the display 12, and the lower side fixing member 22 is placed on the lower side of the display 12. It is placed in a specified position along the line. The target device 11 supports the upper side fixing member 21 and the lower side fixing member 22 by the side support members 25 and 26 so that the target plate 23 and the back surface plate 24 are substantially vertical in front of the display 12. It is possible to maintain a flat shape.

Further, the target device 11 can be configured to have a size corresponding to the screen size of the display 12, and for example, when the target device 11 corresponds to a display 12 having a size of 32 inches or more, the size of the target device 11 is determined. The length x width is about 45 cm x about 80 cm or more. Therefore, if the target device 11 is configured to use a hard plate-shaped member (acrylic resin plate or the like) as the back plate 24, it is not possible to carry or store the large plate-shaped back plate 24. It is not easy, and it is assumed that the target device 11 will be difficult to handle.

Therefore, as described above, the target device 11 is configured by using a soft vinyl chloride resin or the like as the back plate 24 as in the target plate 23. Therefore, the target device 11 has a configuration in which the target plate 23 and the back plate 24 can be wound around the lower side fixing member 22 by removing the side support members 25 and 26, and the target plate 23 and the back plate can be wound up. 24 can be wound into a roll. The target device 11 can be wound around the upper side fixing member 21 as an axis, or both the upper side fixing member 21 and the lower side fixing member 22 as an axis, but the control unit 28 is fixed to the upper side fixing member 21. Since it is configured, it is preferable that only the lower side fixing member 22 is used as an axis.

As described above, the target device 11 has a cylindrical shape having the lengths of the upper side fixing member 21 and the lower side fixing member 22 by making the target plate 23 and the back plate 24 using a soft member windingable. Can be. As a result, the target device 11 can be easily carried together with the soft air gun 17, for example, and the portability can be improved. Similarly, when the target device 11 is stored without being used, it can be stored in a narrow space as compared with a configuration using a rigid plate-shaped member as the back plate 24, for example, behind the display 12. It can be easily cleaned up. That is, the target device 11 can be handled better in terms of portability and storability.

Further, the target device 11 supports the upper side fixing member 21 and the lower side fixing member 22 by the side support members 25 and 26, adjusts the positions of the nuts 31 to 38, and makes the target plate 23 and the back plate 24 to some extent. It can be in a tensioned state. That is, in the target device 11, the upper side fixing member 21 and the lower side fixing member 22 are set at a predetermined interval (relatively specified position), so that the target plate 23 and the back surface plate 24 using the soft member are bent. It is possible to maintain a flat and stretched shape so that it does not exist.

By the way, since the target plate 23 and the back plate 24 use the soft vinyl chloride sheet distributed in the form of a roll, they may have a habit of maintaining a curled state. In this case, the target plate 23 and the back plate 24 having the same thickness (for example, 1.5 mm) are used so that the habits of the target plate 23 and the back plate 24 are in the same direction. The spacing D between the back plates 24 can be constant over the entire surface. As a result, the target device 11 can be configured so that a more stable acoustic signal can be acquired by the acoustic sensor 27.

The target device 11 is used as a configuration in which the positions of the acoustic sensors 27-1 to 27-4 can be moved to the left and right, and the lengths of the upper side fixing member 21 and the lower side fixing member 22 can be expanded or contracted or attached. By using the target plate 23 and the back plate 24 according to the size of the display 12, it is possible to correspond to the display 12 having various sizes or aspect ratios. Similarly, by changing the lengths of the side support members 25 and 26, connecting them using high nuts, etc., it is possible to support displays 12 of various sizes or aspect ratios in the vertical and horizontal directions. Can be done.

Further, the target device 11 can be installed horizontally as shown in the figure, or can be installed, for example, vertically. That is, the target device 11 arranges the upper side fixing member 21 and the lower side fixing member 22 on the left and right sides of the display 12 so as to face in the vertical direction, and the side support members 25 and 26 so as to face in the horizontal direction. It may be installed so as to be arranged above and below the display 12. When the target device 11 is installed vertically in this way, it is possible to support a large screen display 12 by using the longer side support members 25 and 26. In this case, it is preferable to apply tension to the target plate 23 and the back plate 24 in the vertical direction.

Further, the target device 11 can be used by being attached to the display 12, for example, fixed to a wall surface or can be used independently on a table or the like.

FIG. 5 shows an example of use in which the target device 11 is fixed to the wall surface 81.

As shown in FIG. 3 above, a hole 44-1 is formed in the vicinity of the rear end of the main fixing plate 41. Similarly, a hole 44-2 is formed in the vicinity of the rear end of the auxiliary fixing plate 42, and a hole 44-3 is formed in the vicinity of the rear end of the auxiliary fixing plate 43.

Then, as shown in FIG. 5, the target device 11 can be fixed to the wall surface 81 by engaging the holes 44 with respect to the wall hook 82 fixed to the wall surface 81. At this time, similarly to the auxiliary fixing plate 43 attached to the upper side fixing member 21, the auxiliary fixing plate 83 is also attached to the lower side fixing member 22 so that the auxiliary fixing plate 83 appropriately abuts on the wall surface 81. This allows the target device 11 to be kept substantially vertical. Although the auxiliary fixing plate 83 attached to the right side of the target device 11 is shown in FIG. 5, the auxiliary fixing plate 43 attached to the upper side fixing member 21 is also shown on the left side of the target device 11 as well as the auxiliary fixing plate 42. An auxiliary fixing plate (not shown) is attached to the lower side fixing member 22.

When the target device 11 is fixed to the wall surface 81 and used, for example, a target paper (not shown) on which the target image 16 as shown in FIG. 1 is drawn is attached to the back surface of the back plate 24. And shoot at the target paper. Alternatively, a target paper on which the target image 16 is drawn may be placed on the wall surface 81 behind the back plate 24. Further, the back plate 24 or the target plate 23 may be made white or the like, and the target image 16 may be projected on the target plate 23 or the back plate 24 by a projector. Alternatively, the projector screen may be installed on the back surface side of the back plate 24, or the projector screen may be fixed to the wall surface 81 behind the back plate 24, and the target image 16 may be projected on the projector screen. A target paper (not shown) on which the target image 16 is drawn is attached to the surface of the back plate 24 so that the target paper is placed between the target plate 23 and the back plate 24. For example, the slip resistance when the target plate 23 and the back plate 24 come into contact with each other can be eliminated, and the target device 11 can be rolled better.

FIG. 6 shows an example of using the target device 11 independently.

As shown in FIG. 6, the target device 11 attaches the auxiliary fixing plate 83 to the lower side fixing member 22 in the same manner as the auxiliary fixing plate 43 attached to the upper side fixing member 21, and attaches the auxiliary fixing plate 43 and the auxiliary fixing. The self-supporting member 84 can be attached to the plate 83. In FIG. 6, the auxiliary fixing plate 83 and the self-supporting member 84 on the right side of the target device 11 are shown, but the auxiliary fixing plate and the self-supporting member (not shown) are similarly attached to the left side of the target device 11. Has been done.

The self-supporting member 84 is a rod-shaped member (so-called shredded bolt) having a screw formed on the side surface over the entire length like the side support member 26. Then, the nut 85 and the nut 86 are screwed into the screw on the upper part of the self-supporting member 84 so as to sandwich the vicinity of the rear end of the auxiliary fixing plate 43, and the auxiliary fixing plate 83 is screwed into the screw on the lower part of the self-supporting member 84. The nut 87 and the nut 88 are screwed so as to sandwich the vicinity of the rear end.

Then, the target device 11 is self-supporting on a table, for example, at four points by the right side support member 26 and the self-supporting member 84, and the left side side support member 25 and the self-supporting member (not shown). be able to. For example, with the target device 11 standing in front of the display 12, shooting can be performed toward the target image 16 displayed on the display 12. When the target device 11 is used independently, for example, a long side support member 26 and a self-supporting member 84 (also on the left side) may be used. Then, the length of the side support member 26 projecting downward from the lower side fixing member 22 is adjusted, and the length of the self-supporting support member 84 projecting downward from the auxiliary fixing plate 83 is adjusted to adjust the target device 11. The height of the display 12 can be adjusted. Alternatively, a leg portion for adjusting the height at which the target device 11 is arranged by using a connecting member such as a nut (so-called high nut) having a certain length on the side support member 26 and the self-supporting support member 84. (For example, shredded bolts, adjusters, etc.) may be connected. Further, a high nut may be used for the nut 34, the nut 38, the nut 88, etc. provided below the lower side fixing member 22, and the high nut itself may be used as a leg portion.

Further, when the target device 11 is used independently without using the display 12, for example, the target paper (not shown) on which the target image 16 as shown in FIG. 1 is drawn is the back surface of the back plate 24. It is affixed to the target paper and shot at the target paper. Further, the back plate 24 or the target plate 23 may be made white or the like, and the target image 16 may be projected on the back plate 24 or the target plate 23 by a projector. Further, a projector screen may be installed on the back surface side of the back plate 24, and the target image 16 may be projected on the projector screen.

Further, for example, when the target device 11 can be installed close to the display 12, the wall surface, or the like, the configuration may not include the back plate 24. In this case, the impact sound resonates between the target plate 23 and the display 12, the wall surface, or the like, so that a stable acoustic signal can be acquired by the acoustic sensor 27.

In this way, the target device 11 may be fixed to the wall surface 81, the target device 11 may be self-supporting, or the target device 11 may be used while being hung on a stand for a projector screen. Use cases can be applied.

<Second configuration example of the target device>

The target device 11A of the second configuration example will be described with reference to FIGS. 7 to 9. 7 shows a front view of the target device 11A, FIG. 8 shows a plan view of the target device 11A, and FIG. 9 shows a side view of the target device 11A. .. The parts constituting the target device 11A are designated by the same reference numerals as those having the same components as those of the target device 11 described with reference to FIGS. 2 to 4, and detailed description thereof will be omitted.

As described above, the target device 11 of FIGS. 2 to 4 uses the side support members 25 and 26 to support the upper side fixing member 21 and the lower side fixing member 22, thereby supporting the target plate 23 and the back surface plate 24. Is configured to be stretched in a plane.

On the other hand, the target device 11A does not use the side support members 25 and 26, but uses the string 101, the stoppers 102 and 103, and the flat rubber string 104, and the target plate 23 and the back plate 24 are flat. It is configured to be in a stretched state. For example, the string 101 and the stoppers 102 and 103 are held so that the upper side fixing member 21 is horizontal along the upper side of the display 12, and the flat rubber string 104 has the lower side fixing member 22 along the lower side of the display 12. Hold it in a horizontal position.

Specifically, after passing one end of the string 101 through the hole 44-2 of the auxiliary fixing plate 42 from the bottom to the top, the stopper 102 is fixed to one end of the string 101 on the upper surface side of the auxiliary fixing plate 42. Similarly, after passing the other end of the string 101 through the hole 44-3 of the auxiliary fixing plate 43 from the bottom to the top, the stopper 102 is fixed to the other end of the string 101 on the upper surface side of the auxiliary fixing plate 43. Then, when the central portion of the string 101 is pressed by the base on the back side of the display 12, the fixing position of the string 101 by the stopper 102 and the stopper 103 is such that the upper side fixing member 21 is horizontal along the upper side of the display 12. To adjust.

Further, after fixing both ends of the flat rubber string 104 in the vicinity of both ends of the lower side fixing member 22, the central portion of the flat rubber string 104 is displayed so that the lower side fixing member 22 is horizontal along the lower side of the display 12. Hold it with the base on the front side of 12. At this time, the length of the flat rubber cord 104 is adjusted so that appropriate tension is applied to the target plate 23 and the back plate 24.

As described above, the target device 11A uses the string 101 and the stoppers 102 and 103 as a holding portion for holding the upper side fixing member 21 along the upper side of the display 12, and the flat rubber string 104 is used as the lower side fixing member. 22 can be used as a holding portion for holding along the lower side of the display 12. As a result, in the target device 11A, the target plate 23 and the back plate 24 using the soft member can maintain a flatly stretched shape so as not to cause bending.

Further, the target device 11A can wind the target plate 23 and the back plate 24 around the lower side fixing member 22 by simply removing the flat rubber cord 104 from the base on the front side of the display 12, for example. It can be more easily stored behind the display 12. Therefore, the target device 11A can also be handled better in terms of portability and storability.

<Third configuration example of the target device>

FIG. 10 shows a side view of the target device 11B of the third configuration example. The parts constituting the target device 11B are designated by the same reference numerals as those having the same components as those of the target device 11 described with reference to FIGS. 2 to 4 described above, and detailed description thereof will be omitted.

As shown in FIG. 10, the target device 11B does not use the back plate 24 (see FIG. 4), and a member having an L-shaped cross section is used as the upper side fixing member 21B, and the lower side fixing member is used. A flat plate is used as 22B.

Further, in the target device 11B, similarly to the target device 11A of FIGS. 7 to 9 described above, the target plate 23 is stretched in a plane by using the string 101, the stoppers 102 and 103, and the flat rubber string 104. It is configured to be. That is, in the target device 11B, the upper side fixing member 21B is held in a state of being horizontal along the upper side of the display 12 by the string 101 and the stoppers 102 and 103, and the lower side fixing member 22B is held by the flat rubber string 104 in a state of being horizontal. It is held so as to be horizontal along the lower side of the twelve. As shown by the broken line, a spacer 105 (for example, a block made of styrofoam) having a length corresponding to the distance D between the lower side fixing member 22B and the display 12 may be attached to the lower side fixing member 22B. Therefore, the arrangement of the target plate 23 can be stably maintained.

Since the target device 11B does not use the back plate 24, the acoustic sensors 27-1 to 27-4 are arranged in the space 29 of the space D between the target plate 23 and the display 12. It will be. That is, even if the back plate 24 is not used, the acoustic sensors 27-1 to 27-4 can acquire a stable acoustic signal by resonating the impact sound between the target plate 23 and the display 12. ..

When an iron plate or the like having a certain weight is used as the lower side fixing member 22B in the target device 11B, for example, the target plate 23 is put into a state where tension is applied even if the flat rubber string 104 is not used. be able to. That is, in this case, due to the weight of the lower side fixing member 22B, it is possible to maintain a flatly stretched shape so that the target plate 23 does not bend.

Then, the target device 11B can wind the target plate 23 around the lower side fixing member 22B by simply removing the flat rubber cord 104 from the base on the front side of the display 12. Therefore, the target device 11B can also be handled better in terms of portability and storability.

<Fourth configuration example of the target device>

FIG. 11 shows a side view of the target device 11C of the fourth configuration example. The parts constituting the target device 11C are designated by the same reference numerals as those having the same components as those of the target device 11 described with reference to FIGS. 2 to 4 described above, and detailed description thereof will be omitted.

As shown in FIG. 10, the target device 11C has a configuration that does not use the back plate 24 (see FIG. 4), and the cross-sectional shape is bent as shown as the upper side fixing member 21C and the lower side fixing member 22C. A plate-shaped member is used.

For example, the target device 11C is fixed to the wall surface 81 so that the upper side fixing member 21C and the lower side fixing member 22C are parallel to each other and horizontal. At this time, the distance between the upper side fixing member 21C and the lower side fixing member 22C is the length in the vertical direction of the target plate 23 (that is, so as to maintain the shape in which the target plate 23 is stretched in a plane so as to be substantially vertical). It is specified according to the length between the upper side and the lower side).

Further, the target device 11C attaches the flat rubber cord 104 as shown in FIG. 10 to the lower side fixing member 22C so as to lock the flat rubber cord 104 to the wall-mounted hook 82 fixed to the wall surface 81. It may be configured as such. As a result, an appropriate tension is applied to the target plate 23, and the target plate 23 can maintain a flatly stretched shape so as not to cause bending. Alternatively, as the lower side fixing member 22C, an iron plate or the like having a certain weight may be used so that the target plate 23 is tensioned in the downward direction due to the weight of the lower side fixing member 22C. Further, instead of the lower side fixing member 22C having a shape as shown in the drawing, for example, the lower side fixing member 22B to which the spacer 105 as described with reference to FIG. 10 is attached may be adopted.

Also in the target device 11C, the acoustic sensors 27-1 to 27-4 can acquire a stable acoustic signal by resonating the impact sound between the target plate 23 and the wall surface 81.

Then, the target device 11C can wind the target plate 23 around the lower side fixing member 22C by removing the upper side fixing member 21C and the lower side fixing member 22C from the wall surface 81. Therefore, the target device 11C can also be handled better in terms of portability and storability.

<Fifth configuration example of the target device>

The target device 11D of the fifth configuration example will be described with reference to FIGS. 12 to 14. FIG. 12 shows a plan view of the target device 11D, and FIG. 13 shows a front view of the target device 11D. Regarding each part constituting the target device 11D, the same reference numerals are given to the configurations common to the target device 11 described with reference to FIGS. 2 to 4, and detailed description thereof will be omitted.

As described above, the target device 11 of FIGS. 2 to 4 is configured so that the target plate 23 and the back plate 24 maintain a flatly stretched shape, whereas the target device 11D has the target plate 23. And the back plate 24 is configured to maintain a curved shape. As shown in the figure, the target device 11D utilizes the side fixing members 121 and 122, and the spacers 123-1 to 123-14, so that the target plate 23 and the back plate 24 have an arc shape in the left-right direction. It is maintained in such a curved shape.

Similar to the upper side fixing member 21 (see FIG. 4), the side fixing members 121 and 122 are members formed in a straight line having a U-shaped cross section, and are side portions of the target plate 23 and the back plate 24. Is fixed to. As shown in FIG. 13, when the target device 11D is viewed from the front, the side fixing member 121 is fixed to the right side of the target plate 23 and the back plate 24, and the side fixing member 122 is fixed to the target plate 23 and the target plate 23. It is fixed to the left side of the back plate 24. Further, the control unit 28 is attached to the side fixing member 121.

The spacers 123-1 to 123-7 are fixed to the upper sides of the target plate 23 and the back plate 24 at predetermined intervals, and the spacers 123-8 to 123-14 are fixed to the upper sides of the target plate 23 and the back plate 24 at predetermined intervals, respectively. And fixed to the lower side of the back plate 24. Then, the spacers 123-1 to 123-14 maintain the curved shape of the target plate 23 and the back surface plate 24 with a constant distance D from each other. Hereinafter, when it is not necessary to distinguish each of the spacers 123-1 to 123-14 as appropriate, it is simply referred to as the spacer 123.

For example, as shown in FIG. 14, the spacer 123 is provided with rib portions 142 and 143 at one end of the flat plate portion 141 having a length corresponding to the interval D, and rib portions 144 and 143 at the other end. It is a member provided with 145. A screw hole 151 is formed in the flat plate portion 141.

The rib portions 142 and 143 are provided at right angles to the flat plate portion 141 at intervals for sandwiching the target plate 23 between them, for example, a hole 152 is formed in the rib portion 142 and the rib portion 143 has a hole 152 formed therein. Is formed with a screw hole 153. Then, the target plate 23 can be inserted between the rib portions 142 and 143, and a screw can be inserted from the rib portion 142 side to fix the target plate 23. Similarly, the rib portions 144 and 145 are provided at right angles to the flat plate portion 141 at intervals for sandwiching the back plate 24 between them, for example, and the rib portions 144 are formed with screw holes 154 and screw holes 154 are formed. A hole 155 is formed in the rib portion 145. Then, the back plate 24 can be inserted between the rib portions 144 and 145, and the screw can be inserted from the rib portion 145 side to fix the back plate 24.

In this way, in the target device 11D, both side portions of the target plate 23 and the back plate 24 are vertically fixed by the side fixing members 121 and 122, and the upper side and the lower side are fixedly spaced by the spacers 123-1 to 123-14. It is fixed at D. Then, the target device 11D can stand on its own by the curved shape while the target plate 23 and the back plate 24 maintain the curved shape.

Further, as shown in FIG. 12, the target device 11D uses a perforated board 124 having a size that covers the target plate 23 and the back plate 24 as a ceiling, and a screw formed on the flat plate portion 141 of the spacer 123. The holes 151 allow the spacer 123 to be screwed onto the perforated board 124. As a result, the stability when installing the target device 11D can be improved, and the curved shapes of the target plate 23 and the back plate 24 can be freely adjusted to have arbitrary diameters. Of course, the spacer 123 may be arranged linearly so that the target plate 23 and the back surface plate 24 have a planar shape.

Further, the target device 11D is configured to measure the impact sound generated when the BB bullet 18 lands on the target plate 23 by six acoustic sensors 27-1 to 27-6. That is, in the target device 11D, the acoustic sensors 27-1 to 27-4 are arranged at the four corners, and the acoustic sensors 27-5 are added to the center of the upper side, and the acoustic sensors 27-5 are added to the center of the lower side, as in the above-mentioned target device 11. Acoustic sensors 27-6 are added and placed. As described above, by increasing the number of acoustic sensors 27, the target device 11D can prevent the measurement accuracy of the landing position of the BB bullet 18 from being lowered even with the target plate 23 having a larger area. .. Further, as shown in FIG. 12, the acoustic sensors 27-1 to 27-6 can be fixed to the back plate 24.

In the target device 11D configured in this way, a back projection type screen is attached to the back plate 24, or the back plate 24 itself is processed so as to enable back projection. The target image 16 can be projected from the back side of the 11D using the projectors 131-1 to 131-3.

For example, as shown in FIG. 12, the projectors 131-1 to 131-3 are arranged at an angle corresponding to the curved shape of the target device 11D, and have a long laterally long shape as shown by the two-dot chain line in FIG. The image can be projected on the projection area. As a result, the target device 11D can display the target image 16 in a projection area that covers the field of view of the user A in front of the target device 11D, and can experience a more realistic shooting experience. That is, the target device 11D allows the user A to shoot at the target image 16 displayed so as to surround himself / herself.

For example, as shown by the broken line in FIG. 12, the projectors 131-1 to 131-3 may be arranged on the front side of the target device 11D. In this case, the target image 16 is projected from diagonally above or diagonally below the target device 11D by making the target plate 23 and the back plate 24 white or the like, or by attaching a projector screen to the back plate 24. The number and arrangement positions of the projectors 131 are not limited to the example shown in FIG. 12, and appropriate projectors can be adopted according to the size and curved shape of the target device 11D. Further, a curved display may be installed behind the target device 11D.

Further, in the target device 11D, even if the target plate 23 and the back plate 24 have a curved shape, the space 29 between the target plate 23 and the back plate 24 is impacted by maintaining a constant interval D by the spacer 123. Sound resonates and propagates in a stable manner. As a result, in the target device 11D, the acoustic sensors 27-1 to 27-6 can acquire a stable acoustic signal in the same manner as in the configuration in which the target plate 23 and the back plate 24 are flat, and the BB The landing position of the bullet 18 can be accurately detected. When it is not necessary to change the curved shape of the target device 11D, instead of using a plurality of spacers 123, for example, an arc shape having a length along the upper side and the lower side of the target plate 23 and the back plate 24 is formed. Spacers can be used. Further, when the target device 11D has a planar shape, a linear spacer may be used.

Further, by removing the spacer 123, the target device 11D can, for example, wind the target plate 23 and the back plate 24 around the side fixing member 122 into a roll shape. Therefore, as described above, the target device 11D can be handled better in terms of portability and storability.

In the configuration using the spacer 123, the target plate 23 is sandwiched between the rib portions 142 and 143, and the back plate 24 is sandwiched between the rib portions 144 and 145, and the target plate 23 and the back are not screwed. The face plate 24 can be maintained in a curved shape. Further, instead of sandwiching the target plate 23 and the back plate 24, for example, a spacer having a U-shaped cross section in which rib portions 143 and 144 are provided at both ends of the flat plate portion 141 is used. A configuration may be adopted in which the target plate 23 and the back plate 24 are curved by always screwing.

Further, for example, also in the target device 11D, the collection mat 19 as shown in FIG. 1 is arranged on the front side of the target device 11D, and the BB bullet 18 that has landed on the target plate 23 can be collected. For example, a flexible collection mat 19 such as the above-mentioned bore fabric or pile fabric can be easily arranged along the curved shape of the target device 11D.

When using such a collection mat 19, for example, by lifting both ends of the collection mat 19 and narrowing it back and forth, the BB bullets 18 scattered on the collection mat 19 can be collected in the center. can. Then, the BB bullets 18 can be easily collected in a small container by setting the BB bullets 18 to be accumulated in the central depression of the collection mat 19. For example, the so-called microfiber towel is very flexible, so that it can be easily formed into a shape such as conforming to a curved shape or loosening to form a dent, and the shape can be maintained. For example, in a configuration in which a BB bullet 18 is collected using an adhesive gel, even if the BB bullet 18 can be reliably collected, it takes time and effort to remove the BB bullet 18 from the adhesive gel, and the BB bullet 18 is captured. It is difficult to collect the BB bullet 18 as easily as the collecting mat 19.

By the way, in the target device 11 (including each of the above-mentioned configuration examples), by using the thinner target plate 23 and the back plate 24, it is possible to roll the target plate 23 into smaller pieces. Further, in the target device 11, by using the thinner target plate 23 and the back plate 24, the position where the BB bullet 18 lands on the target plate 23 and the position displayed on the display 12 when viewed from the user performing the shooting are displayed. The error with the landing mark P to be made (hereinafter referred to as a visual error) can be reduced. Either the target plate 23 or the back plate 24 may be thinned.

For example, when the back plate 24 is thinned, even if a hard member to some extent is used, it can be rolled like a soft member, and an impact is generated in the space 29 sandwiched between the target plate 23 and the back plate 24. It was also confirmed that the sound pressure of the sound was not significantly attenuated. In a configuration using, for example, a polycarbonate plate having a thickness of 0.2 mm as the back plate 24, the attenuation of the sound pressure of the impact sound is such that the detection of the landing position of the BB bullet 18 is not affected. Further, in the target device 11, by providing the back plate 24, when the acoustic sensor 27 acquires the impact sound, it is possible to reduce the adverse effect of the structure and noise behind the target device 11.

The target device 11 may have a configuration in which the acoustic sensors 27 arranged on the back surface side of the target plate 23 are arranged in the space 29 having a constant interval D, and have a planar shape or a curved shape as described above. In addition, for example, a tubular shape or a dome shape that surrounds the entire circumference (360 °) of the user may be adopted.

By the way, as described above, in the target device 11, a soft sheet-like member that can receive the collision of the BB bullet 18 by bending is adopted for the target plate 23, and the same applies to the back plate 24. The structure is such that a soft sheet-like member is used. As described above, the target device 11 can improve the measurement accuracy by forming the back plate 24 with the soft member.

That is, the impact sound when the BB bullet 18 collides with the target plate 23 and the change in air pressure in the space 29 due to the local dent of the target plate 23 are transmitted to the back plate 24 behind the target plate 23. Will cause vibration. At this time, if the back plate 24 is made of a hard member, the vibration propagating inside the back plate 24 is transmitted to the entire plate, and the vibration may be transmitted to the acoustic sensor 27 as well. For example, when the back plate 24 is made of acrylic resin, vibration propagates inside the back plate 24 at a sound velocity of about 2800 m / sec, which is much faster than in the air, and the vibration is detected by the acoustic sensor 27. , It causes erroneous detection of the landing position and the landing speed of the BB bullet 18.

On the other hand, when the back plate 24 is made of a soft member, the vibration hardly propagates inside the back plate 24, so that the acoustic sensor 27 is prevented from detecting the vibration through the back plate 24. Therefore, as a result of being able to eliminate the cause of erroneously detecting the landing position, landing speed, etc. of the BB bullet 18, the target device 11 can improve the measurement accuracy.

That is, the target device 11 is configured such that vibration is not transmitted from the landing position toward the surroundings via the member, so that the landing position can be accurately detected by the acoustic sensor 27. In this way, the target plate 23 and the back plate 24 are not made of hard members so that vibration is transmitted to the entire plate, but are made of soft members, so that the landing position can be accurately detected. Suitable.

In general, the larger the hard thin plate, the more difficult it is to obtain, and it is difficult to handle and transport it. On the other hand, if it is a soft plate, it is distributed and transported in roll form, so even a large plate can be obtained and transported. Easy to store. Therefore, the target device 11 in which the back plate 24 is made of a soft member can be handled more easily. Further, even if the target plate 23 is greatly bent by the collision of the BB bullet 18 and comes into contact with the back plate 24, since the back plate 24 is a soft member, it does not crack like a hard thin plate. The target device 11 can have a structure that is not easily broken. The target plate 23 with which the BB bullet 18 collides is a consumable item whose surface is gradually scratched or its transparency is lowered with use, and it is preferable to have a replaceable structure. Therefore, by adopting a soft member similar to the target plate 23 as the back plate 24, the target plate 23 can be easily replaced by relaxing the tensions of the target plate 23 and the back plate 24 when the target plate 23 is replaced. It becomes possible to do.

In particular, the hard thin plate must be designed in consideration of expansion and contraction due to temperature as it becomes larger, whereas by making both the target plate 23 and the back plate 24 soft members, the target device 11 can be designed. The same degree of tension will be applied to the front and back, and a more well-balanced configuration can be achieved. Further, since the target device 11 has a simple structure and can apply a constant tension to the target plate 23 and the back plate 24 evenly, it is possible to avoid distortion of the target plate 23 and to stretch them in a well-balanced manner. Can be done.

In particular, the measurement accuracy can be improved by narrowing the distance D between the target plate 23 and the back plate 24, but when the distance D is narrowed, the BB bullet 18 collides with the target plate 23. The vibration at that time is easily transmitted to the back plate 24. Therefore, in the target device 11 having a configuration in which the interval D is narrowed, it is particularly effective to configure the back plate 24 with a soft member in that erroneous detection can be avoided.

Further, in the target device 11 having a configuration in which the distance D between the target plate 23 and the back plate 24 is narrowed in this way, the BB bullet 18 lands on the target plate 23 and a large dent is generated, so that the target plate 23 has a back. It is assumed that it will come into contact with the face plate 24. However, even in such a case, since the back plate 24 is soft, the target device 11 can avoid a situation in which the back plate 24 is cracked, for example, and the interval D is further increased. It can be a narrowed configuration. Further, since the target device 11 has a configuration in which the back plate 24 can be bent together with the target plate 23, the target plate 23 and the back plate 24 can receive the collision, so that, for example, a stronger collision force can be obtained. Can be dealt with without breaking, and versatility can be improved.

<Sixth configuration example of the target device>

The target device 11E of the sixth configuration example will be described with reference to FIGS. 15 and 16. FIG. 15 shows a front view of the target device 11E, and FIG. 16 shows a plan view of the target device 11E. Regarding each part constituting the target device 11E, the same reference numerals are given to the configurations common to the target device 11 described with reference to FIGS. 2 to 4, and detailed description thereof will be omitted.

As shown in FIGS. 15 and 16, in the target device 11E, the side fixing member 201 is attached to the left side when viewed from the front, and the side fixing member 202 is attached to the right side when viewed from the front. It is composed of.

Like the upper side fixing member 21 and the lower side fixing member 22, the side fixing member 201 is a member having a U-shaped cross section as shown in FIG. 16, and the target plate 23 and the back as shown in FIG. It is a member having almost the same length as the vertical width of the face plate 24. Further, the side fixing member 201 has an elongated shape along the left sides of the target plate 23 and the back plate 24, and a plurality of screws are used with respect to the left sides of the target plate 23 and the back plate 24 at predetermined pitch intervals. Is fixed. Further, the side fixing member 202 is a member having the same shape as the side fixing member 201, and is fixed to the right side of the target plate 23 and the back plate 24 by using a plurality of screws at predetermined pitch intervals. To. Of course, a fixing method other than screws may be adopted for fixing the target plate 23 and the back plate 24.

Further, the upper end of the side fixing member 201 is fixed to the upper side fixing member 21 by using the L-shaped metal fitting 211 to which the stud bolt 221 is fixed, and the lower end thereof is L to which the stud bolt 223 is fixed. It is fixed to the lower side fixing member 22 by using the metal fitting 213. For example, the L-shaped metal fitting 211 is fixed to the upper side fixing member 21 by using the nut 31, and is fixed by a machine screw for preventing rotation. Similarly, the L-shaped metal fitting 213 is fixed to the lower side fixing member 22 by using the nut 34, and is also fixed by the machine screw for stopping the rotation.

Then, the nuts 231 and 232 are screwed into the stud bolt 221 so as to sandwich the vicinity of the upper end portion of the side portion fixing member 201, and the vicinity of the lower end portion of the side portion fixing member 201 is sandwiched. Nuts 235 and 236 are screwed onto the stud bolts 223. As a result, the side fixing member 201 is attached to the upper side fixing member 21 and the lower side fixing member 22 so that the positions in the left-right direction can be adjusted by the lengths of the stud bolts 221 and 223.

Similarly, the nuts 233 and 234 are screwed into the stud bolt 222 so as to sandwich the vicinity of the upper end of the side fixing member 202, and the vicinity of the lower end of the side fixing member 202 is sandwiched. , Nuts 237 and 238 are screwed onto the stud bolts 224. As a result, the side fixing member 202 is attached to the upper side fixing member 21 and the lower side fixing member 22 so that the positions in the left-right direction can be adjusted by the lengths of the stud bolts 222 and 224.

In the target device 11E configured in this way, the upper side fixing member 21 and the lower side fixing member 22 not only apply tension to the target plate 23 and the back plate 24 in the vertical direction, but also apply tension in the left-right direction. Therefore, the target plate 23 and the back plate 24 can be stretched more flatly and in parallel. This makes it possible to improve the measurement accuracy. Further, in a structure in which tension is only applied to the target plate 23 and the back plate 24 in the vertical direction, for example, when the size is increased, the left and right ends of the target plate 23 and the back plate 24 are widened and the interval D is opened. Is expected. On the other hand, the target device 11E can prevent the left and right ends of the target plate 23 and the back plate 24 from expanding.

Of course, in the target device 11E, by removing the side fixing member 201 and the side fixing member 202 from the target plate 23 and the back plate 24, the target plate is centered on the lower side fixing member 22 as in the above-mentioned target device 11. The structure is such that the 23 and the back plate 24 can be wound up. That is, the target device 11E can be handled better like the target device 11.

<7th configuration example of target device>

FIG. 17 shows a side view of the target device 11F of the seventh configuration example. The parts constituting the target device 11F are designated by the same reference numerals as those having the same components as those of the target device 11 described with reference to FIGS. 2 to 4 described above, and detailed description thereof will be omitted.

As shown in FIG. 17, the target device 11F does not use the back plate 24 (see FIG. 4), and the target plate 23 is located at a position where the back plate 24 is mounted in the target device 11 of FIG. Is attached and configured. That is, as described above, the soft vinyl chloride sheet is used for both the target plate 23 and the back plate 24, and the target device 11F substantially removes the target plate 23 from the target device 11 in FIG. The structure is such that the face plate 24 is used as the target plate 23.

Further, in the target device 11F, spacers 71F to 74F having a thickness enough to prevent the target plate 23 from coming into contact with the display 12 when the target plate 23 is recessed in response to the collision of the BB bullet 18 (FIG. 17). (Only the spacers 73F and 74F on the left side surface side are shown) are used. For example, when the target device 11F is designed to have a size corresponding to the 32-inch display 12, the thickness of the spacers 71F to 74F is preferably 8 mm or more.

In this way, in the target device 11F, the target plate 23 is arranged on the back side (display 12 side) with respect to the upper side fixing member 21 and the lower side fixing member 22 when viewed from the user side. Although not shown in FIG. 17, the target device 11F has a configuration in which the acoustic sensor 27 is arranged on the front side of the target plate 23 when viewed from the user side. With such a configuration, the effect that the impact sound resonates in the space 29 cannot be obtained as described above, but by directly detecting the impact sound when the BB bullet 18 lands on the target plate 23, If it is in the central region of the target plate 23, the landing position of the BB bullet 18 can be accurately detected. Further, in such a configuration, there is a concern that the BB bullet 18 bounces off and hits the acoustic sensor 27. Therefore, it is preferable that the target device 11F protects the acoustic sensor 27 without adversely affecting the detection of the shock wave by covering the acoustic sensor 27 with, for example, a low-density sponge having a thickness of 2 mm or more.

Further, the target device 11F can arrange the target plate 23 and the display 12 in a narrower distance than the target device 11 in FIG. 4 so that the target plate 23 is closer to the display 12. As a result, it is possible to reduce the visual error between the landing position where the BB bullet 18 has landed on the target plate 23 and the landing mark P displayed on the display 12, and the user can comfortably use the target device 11F. .. Further, the target device 11F has a configuration in which only one of the target plates 23 needs to be rolled when the user carries it, and the target device 11F can be rolled to a smaller diameter. Therefore, the user can comfortably carry the target device 11F.

By the way, in the target device 11 of each of the above-described embodiments, the soft vinyl chloride resin can also be used as a spacer when the substrate of the acoustic sensor 27 is attached to the upper side fixing member 21 and the lower side fixing member 22. For example, a soft vinyl chloride resin with a thickness of 2 mm and a hardness of # 490 is also excellent as a vibration-proof material, has a hardness that hardly conveys sound and is not crushed even when tightened with screws, so the target plate 23 It is possible to prevent the vibration when the BB bullet 18 collides with the BB bullet 18 from propagating from the upper side fixing member 21 or the lower side fixing member 22 and being transmitted to the acoustic sensor 27. This also eliminates the cause of the acoustic sensor 27 erroneously detecting the landing position, landing speed, and the like of the BB bullet 18.

The present embodiment is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present disclosure.

For example, it may be applied to any competition or game in which a flying object hits a target, specifically, a target system such as darts or a blowgun. In this case, instead of the bullet hole mark, a dart or a blowgun arrow may be displayed on the target image. Also, as a matter of course, it is necessary to round the tip of the darts or blowguns instead of BB bullets so that they do not stick to the target plate 23. Further, if the strength of the target plate 23 is increased, the present invention can be applied to a target system of a real gun (air gun or the like) having a stronger energy at the time of landing than a toy gun (soft air gun). Further, in the target device 11 of each configuration example described above, a signal for inputting an acoustic signal output from the acoustic sensor 27 without making the control unit 28 removable or fixing the control unit 28 to the target device 11. It may be configured so that the wires are connected.
