Hereinafter, specific embodiments to which the present technology is applied will be described in detail with reference to the drawings.

<First configuration example of the target system>
FIG. 1 is a diagram showing a configuration example of a first embodiment of a target system to which the present technology is applied.

As shown in FIG. 1, the target system 11 includes a target device 12, a notebook personal computer (hereinafter referred to as a notebook PC) 13, a collection tray 14, and bulletproof plates 15-1 and 15. It is configured with -2.

The target system 11 is used with the display unit 22 opened substantially perpendicular to the main body 21 of the notebook PC 13, and the target device 12 is arranged in front of the display unit 22 of the notebook PC 13. For example, in the target system 11, the target device 12 and the notebook PC 13 can be connected via a communication cable 23 (see FIG. 5 or FIG. 6) described later. The target device 12 and the notebook PC 13 may be wirelessly connected to each other.

Further, in the target system 11, the collection tray 14 is arranged on the lower side in front of the target device 12, and in the illustrated configuration example, the collection tray 14 is installed on the keyboard of the main body 21 of the notebook PC 13. .. Further, in the target system 11, the bullet shield plates 15-1 and 15-2 are fixed so as to extend forward from the right side surface and the left side surface of the target device 12, respectively.

Then, in the target system 11, the display unit 22 of the notebook PC 13 displays the target image 16 showing the target when shooting. For example, when the user shoots at the target image 16 with the muzzle of the soft air gun 31 aimed at the target system 11, the BB bullet 32 fired from the soft air gun 31 flies along the alternate long and short dash line shown in FIG. After that, it lands on the target device 12. At this time, in the target system 11, the landing position where the BB bullet 32 has landed on the target device 12 is detected, and the landing mark P indicating the landing position is superimposed and displayed on the target image 16.

Further, when the BB bullet 32 lands on the target device 12, the target plate 42 (see FIGS. 2 to 4) of the target device 12 bends to absorb the collision momentum of the BB bullet 32, and the BB bullet 32 is caught. It falls on the collection tray 14. Further, when the BB bullet 32 is fired by the soft air gun 31 from a direction oblique to the target device 12 in the horizontal direction instead of from the front, it is assumed that the BB bullet 32 landing on the target device 12 bounces in the left-right direction. Will be done. Even in such a case, the BB bullet 32 is bounced off by the bullet shield plates 15-1 and 15-2 and falls on the collection tray 14. Therefore, in the target system 11, the collection tray 14 can catch and collect the BB bullets 32, and the BB bullets 32 that have landed on the target device 12 can be collected without being scattered.

The target system 11 is configured in this way, and has a detection function for detecting the landing position of the BB bullet 32 fired from the soft air gun 31 landing on the target device 12, and catching the BB bullet 32 landing on the target device 12. It has a collection function for collecting with the collection tray 14.

<Configuration example of target device>
A configuration example of the target device 12 will be described with reference to FIGS. 2 to 4. FIG. 2 is a front view of the target device 12, FIG. 3 is a plan view of the target device 12, and FIG. 4 is a side view of the target device 12.

As shown in FIGS. 2 to 4, the target device 12 includes a frame body 41, a target plate 42, a back plate 43, acoustic sensors 44-1 to 44-4, and a control unit 45.

For example, the target device 12 has a structure in which the target plate 42 is attached so as to cover the opening on the front side of the frame 41, and the back plate 43 is attached so as to cover the opening on the back side of the frame 41. There is. Then, in the target device 12, the acoustic sensors 44-1 to 44-4 are arranged in the space surrounded by the frame body 41, the target plate 42, and the back plate 43. Further, in the target device 12, a main fixing plate 46 and auxiliary fixing plates 47 and 48 used for mounting the target device 12 on the notebook PC 13 are fixed to the upper part of the frame body 41, and the target device 12 is fixed to the main fixing plate 46. On the other hand, it has a structure in which the control unit 45 is mounted.

The frame body 41 is a frame formed in a rectangular shape when viewed from the front, and is formed in a size that surrounds the target image 16 displayed on the display unit 22 of the notebook PC 13 of FIG. Further, as shown in FIG. 2, the inner dimensions (dimensions of the opening portion) of the frame body 41 are height H and width W, and as shown in FIG. 4, the depth dimension of the frame body 41 is depth D. And.

Further, for the frame body 41, for example, a configuration in which an upper side frame member 41a, a lower side frame member 41b, a left side frame member 41c, and a right side frame member 41d are combined can be adopted. For example, in the illustrated configuration example, the upper side frame member 41a, the lower side frame member 41b, the left side frame member 41c, and the right side frame member 41d are similarly linearly formed members having a U-shaped cross section. Has been done. In addition to such a configuration, the frame body 41 may be configured by, for example, integrally molding.

The target plate 42 is made of a soft sheet-like member that can be received by bending the collision when the BB bullet 32 fired by the soft air gun 31 lands and suppresses the repulsion of the BB bullet 32. Further, a transparent member is adopted for the target plate 42 so that the user who shoots with the soft air gun 31 can visually recognize the target image 16 displayed on the display unit 22 of the notebook PC 13. For example, for the target plate 42, it is preferable to use a soft vinyl chloride resin having a thickness of 3.0 mm or the like as a material having a slow restoration rate against deformation due to impact. Further, the target plate 42 is flat as a whole in a state of being stretched so as to be substantially vertical in front of the display unit 22 of the notebook PC 13, that is, in a plane so as not to cause bending. The outer circumference is attached to the front of the.

For the back plate 43, a transparent and hard plate-shaped member, for example, a PET (Polyethylene terephthalate) resin having a thickness of 2.0 mm or the like can be adopted.

The acoustic sensors 44-1 to 44-4 acquire, for example, an impact sound generated when the BB bullet 32 lands on the target plate 42, and do not show an acoustic signal according to a change in the amplitude of the acquired impact sound. It is supplied to the control unit 45 via the signal line. Further, the acoustic sensors 44-1 to 44-4 are located in the vicinity of the four corners of the target plate 42 in a closed space in the housing of the target device 12 surrounded by the frame 41, the target plate 42, and the back plate 43, respectively. It is placed in the position where. For example, as shown in FIG. 2, when viewed from the front, the acoustic sensor 44-1 is arranged near the upper left corner, the acoustic sensor 44-2 is arranged near the upper right corner, and the acoustic sensor 44-3 is located near the lower left corner. It is located in the vicinity, and the acoustic sensor 44-4 is located in the vicinity of the lower right corner. In the following, when it is not necessary to distinguish each of the acoustic sensors 44-1 to 44-4 as appropriate, it is simply referred to as the acoustic sensor 44.

The control unit 45 is subjected to signal processing on an acoustic signal supplied from the acoustic sensor 44, and a signal processing substrate for obtaining a detection signal used for detecting the landing position and landing speed of the BB bullet 32 from the acoustic signal. Is stored. For example, the signal processing board amplifies the acoustic signal, performs full-wave rectification, and holds the peak value of the amplitude. The peak hold signal and the signal obtained by integrating the peak hold signal become equal to or higher than the reference value. Signal processing is performed to output the impact sound detection time signal indicating the above as a detection signal. Then, this detection signal is supplied to the notebook PC 13 via, for example, a communication cable 23 (see FIG. 5 or FIG. 6) connected to the control unit 45.

Then, based on the detection signal supplied from the control unit 45, a program for calculating the landing position and the landing speed of the BB bullet 32 is executed on the notebook PC 13, and the landing mark P (see FIG. 1) is displayed on the display unit 22 of the notebook PC 13. ) Is displayed. A method for calculating the landing position, landing speed, and the like of the BB bullet 32 is disclosed in detail in Patent Document 1 described above.

Here, in the target device 12, the back plate 43 is attached so as to be completely fixed to the back surface of the frame body 41, whereas the target plate 42 is at least partially loose with respect to the front surface of the frame body 41. It is attached. That is, the target plate 42 is not completely fixed to the front surface of the frame body 41, but is attached to the frame body 41 so as to have a certain degree of freedom of movement. That is, it is preferable that the target plate 42 is attached to the frame body 41 so that the outer periphery thereof is held with a predetermined gap, for example, with a margin that allows the target plate 42 to move freely by the gap. It is sufficient that such a gap is provided on at least one side of the target plate 42, and if the target plate 42 is loosely attached to the frame body 41, the gap may not be provided.

Specifically, the target device 12 is provided with a plurality of screw holes at predetermined intervals on the front surface and the back surface of the frame body 41, and a plurality of penetrations are provided on the outer periphery of the target plate 42 and the back surface plate 43 so as to correspond to the screw holes. It is possible to adopt a configuration in which the target plate 42 and the back plate 43 are attached to the frame 41 by providing holes and using machine screws. The back plate 43 is completely fixed to the frame 41 by being sandwiched between the head of the machine screw and the back of the frame 41 without a gap.

On the other hand, as shown enlarged in FIG. 4, the target plate 42 has a predetermined gap between the head 51 of the machine screw and the target plate 42, or between the target plate 42 and the frame 41. It is attached to the frame 41 using machine screws so that it can be provided. That is, when a machine screw is screwed into the screw hole of the frame body 41 through the through hole of the target plate 42, the distance between the head portion 51 of the machine screw and the front surface of the frame body 41 is the distance between the target plate 42. The thickness should be greater than or equal to the thickness so that the target plate 42 is not completely sandwiched between the head 51 of the machine screw and the front surface of the frame 41. For example, it is preferable to provide a gap such that the machine screw is returned from half a turn to one turn after the target plate 42 is sandwiched between the head 51 of the machine screw without a gap. Alternatively, for example, it is preferable to set the depth of the screw hole for attaching the machine screw so that a slight gap is provided even when the machine screw is completely fastened.

The target device 12 is configured in this way, and by loosely attaching the target plate 42 to the frame body 41, a detection range capable of accurately detecting the landing position where the BB bullet 32 has landed on the target plate 42 can be obtained. , The height H and the width W of the inner dimensions of the frame body 41 can be made to be the same. That is, in a range wider than the height H and the width W of the inner dimension of the frame body 41, the frame body 41 is on the back side of the target plate 42, whereas the height H of the inner dimension of the frame body 41 and the width W are wide. In the range of the width W, the back side of the target plate 42 is a space, and the area where the back side is a space can be set as the detection range.

For example, in a configuration in which the target plate 42 is completely fixed to the front surface of the frame body 41, even if the range is inside the height H and the width W of the inner dimensions of the frame body 41, the area in the vicinity of the frame body 41 Then, it was difficult to accurately detect the landing position where the BB bullet 32 landed on the target plate 42. That is, in this configuration, when the BB bullet 32 lands in the region near the frame 41, the target plate 42 cannot be sufficiently bent, and the BB bullet 32 lands on the central portion of the target plate 42. Different impact sounds are generated, and the reproducibility of the impact sounds is reduced. Therefore, the ability to detect the landing position based on the impact sound is also reduced.

On the other hand, the target device 12 loosely attaches the target plate 42 to the front surface of the frame 41 so that the target plate 42 is in the vicinity of the frame 41 up to the limit of the height H and the width W of the inner dimensions of the frame 41. Even in this region, the landing position where the BB bullet 32 lands on the target plate 42 can be accurately detected. That is, in the target device 12, the target plate 42 can be sufficiently bent even when the BB bullet 32 lands on the region near the frame 41, so that when the BB bullet 32 lands on the central portion of the target plate 42, An impact sound close to is generated. Therefore, in the target device 12, the detection performance of the landing position based on the impact sound, even when the BB bullet 32 lands on the central portion of the target plate 42 or when the BB bullet 32 lands on the region near the frame 41. Can be secured. That is, the target device 12 can accurately detect the landing position where the BB bullet 32 has landed on the target plate 42, as compared with the configuration in which the target plate 42 is completely fixed to the front surface of the frame body 41. The range can be widened.

Further, in the target device 12, the acoustic sensors 44 are parallel to each other by arranging the acoustic sensors 44 in a closed space in the housing of the target device 12 surrounded by the frame body 41, the target plate 42, and the back plate 43. It is possible to obtain an impact sound that resonates between the target plate 42 and the back plate 43 that face each other. As a result, the acoustic sensor 44 can obtain the effect of reducing the influence of the external sound, and in addition, the percussion instrument such as a drum or a timpani can generate a stable sound. , A stable acoustic signal can be obtained. As a result, it is possible to suppress the difference in the detected value for each acoustic sensor 44 and improve the measurement accuracy and stability.

At this time, in the target device 12, the landing position can be obtained with higher accuracy by providing a predetermined gap between the frame body 41 and the target plate 42. That is, in the target device 12, even if the volume of the space in the housing in which the acoustic sensor 44 is arranged is sharply reduced due to the bending of the target plate 42 due to the impact of the BB bullet 32, the frame 41 and the target plate 42 Air is properly discharged through the gap between them. As a result, the increase in pressure in the space inside the housing when the BB bullet 32 lands can be appropriately suppressed, so that the impact sound can be stably acquired by the acoustic sensor 44. Therefore, as a result of stabilizing the amplitude of the acoustic signal output from the acoustic sensor 44, the target device 12 suppresses variations in the landing position and the like obtained based on the acoustic signal, and the detection accuracy of the landing position and the like is suppressed. Can be improved.

As described above, the target system 11 has a configuration in which the target plate 42 is loosely attached to the front surface of the frame 41 in the target device 12, so that the detection range in which the landing position can be accurately detected can be widened. , The detection accuracy can be improved, and the performance can be improved.

<Usage example of target system 11>
An example of using the target system 11 will be described with reference to FIGS. 5 and 6. FIG. 5 is a front view of the target system 11 in a used state, and FIG. 6 is a side view of the target system 11 in a used state.

As shown in FIGS. 5 and 6, in the target system 11, the target device 12 is in front of the display unit 22 in a state of being opened substantially perpendicular to the main body 21 of the notebook PC 13, and is the main body of the notebook PC 13. It is placed above 21. For example, the main fixing plate 46 is placed on the upper side of the display unit 22 with a spacer 52 interposed between the upper side of the display unit 22 and the lower surface of the main fixing plate 46 (the same applies to the auxiliary fixing plates 47 and 48). As a result, the target device 12 is attached to the notebook PC 13.

Then, in the target system 11, the control unit 45 of the target device 12 and the main body 21 of the notebook PC 13 are connected by the communication cable 23.

For example, as shown in the figure, in a configuration in which a connection port for connecting the connector of the communication cable 23 is provided on the side surface of the control unit 45, a protective plate 49 for protecting the connector of the communication cable 23 is fixed to the front surface of the control unit 45. It is preferable to do so. The protective plate 49 is provided so as to extend toward the side surface of the control unit 45 so as to hide the connector of the communication cable 23 connected to the side surface of the control unit 45 when the target system 11 is viewed from the front.

For example, a soft vinyl chloride resin having a thickness of 2.0 mm or the like is used for the protective plate 49. Then, the protective plate 49 can protect the connector of the communication cable 23 from the landing of the BB bullet 32 and prevent the BB bullet 32 from directly landing on the control unit 45. By providing the protective plate 49 in this way, for example, it is possible to suppress the rebound of the BB bullet 32 as compared with the configuration in which the BB bullet 32 directly lands on the control unit 45 without providing the protective plate 49. .. Instead of providing the protective plate 49, a configuration may be adopted in which the control unit 45 and the communication cable 23 are protected by extending the upper side of the target plate 42 to the height of the control unit 45.

Further, in the target system 11, a front protective plate 61 that protects the main body 21 from the impact of the BB bullet 32 is fixed to the front surface of the collection tray 14 arranged on the keyboard of the main body 21 of the notebook PC 13. The front protective plate 61 is provided so as to extend downward from the collection tray 14 so that the main body 21 of the notebook PC 13 is hidden when the target system 11 is viewed from the front.

Further, the collection tray 14 has a configuration in which a plurality of convex members 62 are attached to the peripheral portion of the bottom surface. For example, by using a rubber-like member as the convex member 62, the collection tray 14 can be stably arranged by preventing slippage while being installed on the upper surface of the main body 21 of the notebook PC 13.

The collection tray 14 has a configuration in which a plurality of convex members 62 abut on the main body 21 while being arranged on the main body 21 of the notebook PC 13. For example, in the examples shown in FIGS. 5 and 6, the collection tray 14 has a configuration in which four convex members 62-1 to 62-4 are attached in the vicinity of the four corners of the bottom surface. That is, the convex member 62-1 is attached to the left front corner of the bottom surface of the collection tray 14, and the convex member 62-2 is attached to the right front corner of the bottom surface of the collection tray 14. 62-3 is attached to the right back corner of the bottom surface of the collection tray 14, and the convex member 62-4 (not shown) is attached to the left back corner of the bottom surface of the collection tray 14. To.

Therefore, in the target system 11, the collection tray 14 has a bottom surface of the collection tray 14 corresponding to the height of the convex member 62 with respect to the upper surface (for example, a keyboard, a touch pad, etc.) of the main body 21 of the notebook PC 13. It is placed in a floating state. As a result, for example, when the BB bullet 32 that has landed on the target plate 42 falls on the collection tray 14, the bottom surface of the collection tray 14 can be bent, and the bending absorbs the impact of the fall of the BB bullet 32. be able to. That is, by providing a gap between the bottom surface of the collection tray 14 and the installation surface on which the collection tray 14 is installed, it is possible to suppress the rebound of the BB bullet 32 that has fallen on the collection tray 14.

As a result, the target system 11 suppresses the BB bullets 32 that have fallen on the collection tray 14 from being scattered outside the collection tray 14, and reliably collects the BB bullets 32 that have landed on the target plate 42, that is, It is possible to improve the collection method of the BB bullet 32.

The collection tray 14 may be in a state where at least a part of the collection tray 14 is floated from the installation surface. For example, a part of the bottom surface of the collection tray 14 is formed in a convex shape without using the convex member 62. , The convex shape may be configured to come into contact with the installation surface. In addition, the collection tray 14 is in a state where at least a part of the bottom surface of the collection tray 14 is floated from the installation surface so as to be provided with a gap capable of generating a deflection capable of absorbing the impact of dropping the BB bullet 32. Any shape may be used as long as it is configured to be. Further, by arranging the collection tray 14, the upper surface of the main body 21 of the notebook PC 13 can be protected.

Further, in the target system 11, the height of the spacer 52 can be adjusted, and by selectively changing the height of the spacer 52, the target device 12 is attached to the notebook PC 13 having various screen sizes. be able to. For example, FIGS. 5 and 6 show a configuration example in which the target device 12 is mounted on a notebook PC 13 having a screen size of 15.6 inches, and one plate-shaped member having a thickness of 10 mm is used as the spacer 52. ing.

On the other hand, FIG. 7 shows a configuration example in which the target device 12 is attached to the notebook PC 13a having a screen size of 13.3 inches. In this configuration example, five plate-shaped members having a thickness of 10 mm are used as the spacer 52a. That is, since the height of the display unit 22a of the notebook PC 13a is lower than the height of the display unit 22 of the notebook PC 13 of FIG. 6, the display unit is increased by increasing the number of plate members used as the spacer 52a to increase the spacer 52a. The target device 12 can be mounted so as to have an appropriate height with respect to 22.

Further, in the target system 11, when the height of the target device 12 with respect to the display unit 22 is adjusted by using the spacer 52, the fixed positions of the bullet shield plates 15-1 and 15-2 in the height direction are adjusted. May be good. For example, when a small notebook PC 13 is used, it can be made easier to use by adjusting the fixed positions of the bullet shield plates 15-1 and 15-2 in the height direction to be higher.

<Second configuration example of the target system>
FIG. 8 is a diagram showing a configuration example of a second embodiment of the target system to which the present technology is applied.

As shown in FIG. 8, the target system 11A includes a target device 12A, a notebook PC 13, a collection tray 14A, bullet shield plates 15A-1 and 15A-2, and a display 81.

In the target system 11A, the target device 12A is arranged in front of the display 81, and the notebook PC 13 is arranged in the hand of the user who shoots. In the target system 11A, the target device 12A and the notebook PC 13 are connected via the communication cable 82, and the notebook PC 13 and the display 81 are connected via the video cable 83. A configuration in which these are connected wirelessly may be adopted.

Further, also in the target system 11A, as in the target system 11 of FIG. 1, a collection tray 14A is arranged below the front of the target device 12A and extends forward from each of the left and right side surfaces of the target device 12A. The bulletproof plates 15A-1 and 15A-2 are fixed so as to be present.

Then, in the target system 11A, the target image 16 is displayed on the display unit 22 of the notebook PC 13, and the target image 16 is also displayed on the display 81. Therefore, the user shoots at the target image 16 of the display 81 with the muzzle of the soft air gun 31 aimed at the target system 11, and the landing mark P indicating the landing position where the BB bullet 32 has landed on the target device 12 is displayed. It is displayed on both the unit 22 and the display 81. Therefore, in the target system 11A, the user can confirm the landing position of the BB bullet 32 in detail by the landing mark P displayed superimposed on the target image 16 on the display unit 22 of the notebook PC 13.

<Usage example of target system 11A>
An example of using the target system 11A will be described with reference to FIGS. 9 to 11. 9 is a front view of the target system 11A in a used state, FIG. 10 is a plan view of the target system 11A in a used state, and FIG. 11 is a side view of the target system 11A in a used state.

For example, as shown in FIG. 11, in the target system 11A, the target device 12A has a spacer 52A interposed between the upper side of the display 81 and the lower surface of the main fixing plate 46A (the same applies to the auxiliary fixing plates 47A and 48A). The main fixing plate 46A is placed on the upper side of the display 81. Further, in the target system 11A, legs 91-1 and 91-2 having an adjuster function capable of adjusting the height are attached to the left and right of the lower portion of the target device 12A, respectively, and the legs 91 The target device 12A can be supported by -1 and 91-2.

For example, as shown in FIG. 9, the leg 91-1 is attached to the lower left side of the target device 12A, and the leg 91-2 is attached to the lower right side of the target device 12A. With such a configuration, the balance between the left and right heights can be adjusted by utilizing the adjuster functions of the legs 91-1 and 91-2 so that the target device 12A is horizontal when viewed from the front.

Further, the target system 11A has a configuration in which legs 92-1 to 92-4 having an adjuster function capable of adjusting the height are attached to the vicinity of the four corners of the bottom surface of the collection tray 14A. That is, the leg 92-1 is attached to the left front corner of the bottom surface of the collection tray 14A, and the leg 92-2 is attached to the right front corner of the bottom surface of the collection tray 14A. 3 is attached to the right back corner of the bottom surface of the collection tray 14A, and the legs 92-4 (not shown) are attached to the left back corner of the bottom surface of the collection tray 14A.

Then, in the target system 11A, using the adjuster function of the legs 92-1 to 92-4, the BB bullet 32 on the collection tray 14A rolls toward one place with respect to the collection tray 14A. It is in a state of being inclined. For example, as shown in FIG. 10, an opening is formed in the left back corner of the collection tray 14A so that the BB bullet 32 can pass through, and the left back side of the collection tray 14A is the lowest. An inclination is provided with respect to the collection tray 14A.

For example, as shown in FIG. 9, the collection tray 14A is provided with an inclination such that the right side is high and the left side is low when the target device 12A is viewed from the front. Then, in the target system 11A, the collection case 84 is arranged directly under the opening formed in the collection tray 14A, and the BB bullet 32 that has fallen into the collection tray 14A rolls and passes through the opening of the collection tray 14A. Then, it can be configured to be collected in the collection case 84.

Here, the structure of the collection tray 14A will be described with reference to FIG.

A in FIG. 12 shows a plan view of the collection tray 14A, and B in FIG. 12 shows a cross section at arrows AA shown in A in FIG.

As shown in FIG. 12, the collection tray 14A is composed of a tray body 101, a plate member 102, and convex members 103-1 to 103-8.

The tray body 101 is composed of a bottom portion having a rectangular bottom surface and a wall portion surrounding the bottom portion.

The plate member 102 is a plate-shaped member slightly smaller than the bottom of the tray body 101, and is housed inside the tray body 101.

The convex members 103-1 to 103-8 are attached to the peripheral portion of the bottom surface of the plate member 102, and a gap is provided so that at least a part of the plate member 102 floats with respect to the bottom portion of the tray body 101. ..

For example, in the collection tray 14A, as shown in B of FIG. 12, the end portion of the plate member 102 is floated from the bottom of the tray main body 101 by the convex member 103. In this way, the collection tray 14A is configured such that a gap is provided between the plate member 102 and the bottom of the tray main body 101 by keeping the plate member 102 floating from the bottom of the tray main body 101.

The collection tray 14A is configured in this way, and when the BB bullet 32 falls on the collection tray 14A, the plate member 102 can bend, and the bending absorbs the impact of the drop of the BB bullet 32. Can be done. That is, by providing a gap between the plate member 102 and the bottom of the tray body 101, it is possible to suppress the rebound of the BB bullet 32 that has fallen on the collection tray 14A.

As a result, in the target system 11A, it is possible to suppress the BB bullets 32 that have fallen on the collection tray 14A from being scattered outside the collection tray 14A, and to improve the collection method of the BB bullets 32.

<Third configuration example of the target system>
FIG. 13 is a diagram showing a configuration example of a third embodiment of the target system to which the present technology is applied.

As shown in FIG. 13, the target system 11B includes a target device 12B and a notebook PC 13. The target system 11B includes a collection tray 14 and bullet shield plates 15-1 and 15-2, as in the target system 11 of FIG. 1, but their illustrations are omitted.

The target system 11B is used with the target device 12B fixed to the display unit 22 of the notebook PC 13 with the display unit 22 opened substantially perpendicular to the main body 21 of the notebook PC 13.

The target device 12B has a structure in which a target plate 42B and a back plate 43B are attached to the front surface and the back surface of the frame body 41B, respectively, and is in a space surrounded by the frame body 41B, the target plate 42B, and the back surface plate 43B. The signal processing board 111 is housed on the upper side of the above. That is, the target device 12B is configured to have a height required for accommodating the signal processing board 111 more than the target device 12 of FIG. 1, and is fixed to the display unit 22 of the notebook PC 13 in a state of being fixed to the display unit 22. The structure is such that the signal processing board 111 is arranged at a higher position than the above. As a result, the target device 12B can be configured to save more space without providing the control unit 45 that houses the signal processing board in the target device 12.

Further, a rubber foot 112 is attached to the lower surface of the frame body 41B, and the target device 12B is installed in a state where the rubber foot 112 is in contact with the main body 21 of the notebook PC 13. A sponge 113 is attached to the back surface of the back plate 43B, and the target device 12B is installed with the sponge 113 in contact with the display unit 22 of the notebook PC 13. Although only two sponges 113-1 and 113-2 are shown in FIG. 13, the sponges 113 are arranged at four locations on the back plate 43B, and the target device 12B is the four sponges 113. It is configured to come into contact with the display unit 22 via.

The target device 12B is provided with a fixing portion 114 for sandwiching and fixing the display portion 22 of the notebook PC 13. The fixing portion 114 includes a plate member 121, a spacer 122, a support member 123, and a corrugated sponge 124.

The plate member 121 is attached to the upper side of the back plate 43B, and has a thickness capable of providing, for example, a screw hole of a screw used for fixing the spacer 122 and the support member 123. The spacer 122 is a plate-shaped member for adjusting the distance between the plate member 121 and the support member 123, and the number of spacers 122 is adjusted according to the thickness of the display unit 22. The support member 123 is fixed to the plate member 121 via the spacer 122 so as to extend downward from the spacer 122. The corrugated sponge 124 is attached to the display portion 22 near the tip of the support member 123, and is deformed when the corrugated unevenness abuts on the display portion 22.

By providing such a fixing portion 114, the target device 12B can be reliably fixed to the display portion 22 having a desired thickness (for example, 6.6 to 16.5 mm). For example, in addition to adjusting the number of spacers 122, the display portion 22 can be sandwiched between the sponge 113 and the corrugated sponge 124 with a constant pressing pressure within the range where the convex portion of the corrugated sponge 124 is crushed. Instead of the spacer 122, a hinge member may be provided between the plate member 121 and the support member 123. In such a configuration, the display unit 22 can be sandwiched between the sponge 113 and the corrugated sponge 124 by the force of the spring of the hinge member, and the structure can be easily attached to the display unit 22 having various thicknesses. it can.

Further, it is assumed that the target device 12B transmits the impact of the BB bullet 32 landing on the target plate 42B to the display unit 22. However, the target device 12B is configured to come into contact with the display unit 22 via the sponge 113 to alleviate the impact of the impact from being transmitted to the display unit 22 (for example, the force required to open and close the display unit 22). It can be confirmed that it is about 1/10). As a result, even with a fixing method such as the target device 12B, it is considered that the landing of the BB bullet 32 on the target plate 42B does not adversely affect the opening / closing mechanism of the display unit 22.

The target device 12B having the above configuration can realize, for example, more space-saving and more reliable fixation to the notebook PC 13 as compared with the above-mentioned target device 12.

In the present embodiment, as shown in FIG. 2, a configuration using four acoustic sensors 44-1 to 44-4 has been described, but the number of acoustic sensors 44 is not limited to four. Absent. For example, a number of acoustic sensors 44 that can appropriately measure the landing position and the like can be used according to the size or shape of the target device 12, such as 3, 6, and 8. For example, when six acoustic sensors 44 are used, the acoustic sensors 44 are arranged not only at the four corners but also at the center of the upper side and the center of the lower side.

Further, the target system 11 may be applied to, for example, 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, darts or blowgun arrows may be displayed on the target image instead of the landing mark P, and images representing various collisions can be displayed without being limited to the landing mark P. Also, as a matter of course, it is necessary to round the tip of the darts or blowgun arrows instead of the BB bullets 32 so that they do not stick to the target plate 42. Further, if the strength of the target plate 42 is increased, the present invention can be applied to a target system of a real gun (air gun or the like) having stronger energy at the time of impact than a toy gun (soft air gun).

Further, in the target system 11A, a paper on which the same target is drawn can be attached to the back plate 43 of the target device 12A, or the same target can be attached to the back plate 43 without using the display 81 for displaying the target image 16. You may draw it. Further, the back plate 43 or the target plate 42 may be made opaque such as white, and the target image 16 may be projected on the back plate 43 or the target plate 42 by a projector. Similarly, in the target system 11, the paper on which the target is drawn may be used, or the target image 16 may be projected by the projector.

Here, when the target device 12 is used without being attached to the display unit 22 or the display 81 of the notebook PC 13, it is necessary to enable the target device 12 to stand on its own. For example, the target device 12 can be made to stand on its own by using the bulletproof plates 15-1 and 15-2 by extending the bulletproof plates 15-1 and 15-2 to the rear and extending them downward. Can be done. Further, the target device 12 may be provided with a leg portion. Further, in the target system 11, when a paper target is attached to the back side of the target device 12 and used, the convenience can be improved by allowing the target system 11 to stand on a tripod.

<Fourth configuration example of the target system>
A fourth embodiment of the target system to which the present technology is applied will be described with reference to FIGS. 14 and 15. FIG. 14 is a front view showing a configuration example of the target device 12C, and FIG. 15 is a side view showing a configuration example of the target device 12C. In the target device 12C shown in FIGS. 14 and 15, the same reference numerals are given to the configurations common to the target device 12 of FIGS. 2 and 4, and detailed description thereof will be omitted.

That is, the target device 12C has a configuration in which the target plate 42C is attached to the frame body 41C differently from the target device 12 of FIGS. 2 and 4, and is otherwise common. As described above, in the target device 12, the target plate 42 is loosely attached to the frame body 41. For example, the machine screw for attaching the target plate 42 to the frame body 41 starts from half a turn with respect to the fixed state. It is in a loosened state so as to provide a gap for returning one turn.

On the other hand, in the target device 12C, a plurality of locations on the upper side of the target plate 42C are fixed to the frame body 41C, and two locations, the lower left corner and the lower right corner of the target plate 42C, are fixed to the frame body 41C. The target plate 42C is attached to the frame body 41C. That is, the upper side of the target plate 42C is fixed without a gap with the frame body 41C, while the lower side, the right side, and the left side of the target plate 42C have a predetermined gap with the frame body 41C. , The target plate 42C is attached to the frame 41C.

In the configuration examples shown in FIGS. 14 and 15, the five upper sides of the target plate 42C are fixed to the frame 41C by the machine screws 53-1 to 53-5, and the lower left corner of the target plate 42C is the machine screw 53-. 6 is fixed to the frame 41C, and the lower right corner of the target plate 42C is fixed to the frame 41C by the machine screw 53-7. Therefore, only the upper end and the lower end of the left side and the right side of the target plate 42C are fixed to the frame body 41C, respectively.

As a result, as shown in an enlarged manner in FIG. 15, the left side and the right side of the target plate 42C are provided with a gap d from the frame body 41C in the portions other than the upper end and the lower end, respectively, and are in a state of floating from the frame body 41C. .. Although not shown, the lower side of the target plate 42C is also provided with a similar gap d with respect to the frame body 41C at a portion other than the right end and the left end. The gap d is preferably designed to be, for example, about 1 to 3 mm. The gap d may be such that the target plate 42C does not come into contact with the frame body 41C when the target device 12C is upright, and even if the gap d is not provided, the left side and the right side of the target plate 42C are provided. , And other than both ends of the lower side are fixed by machine screws, which is more preferable.

Further, in the target device 12C, when the target plate 42C is fixed to the frame body 41C, the machine screw 53-6 is in a state where the target plate 42C is tensioned in the downward left direction, and the machine screw 53-7 is placed. , The target plate 42C is designed so as to be in a state where tension is applied toward the lower right direction. For example, in the target device 12C, the distance between the through holes provided at the left and right ends of the lower side of the target plate 42C is slightly smaller than the distance between the screw holes provided at the left and right ends of the lower side of the frame 41C (for example, the vertical distance is 1. It is configured to be narrow (5 mm, lateral spacing is about 2 mm). Further, for example, the vinyl chloride resin sheet used as the target plate 42C is immediately changed from the rolled state to the flat state, and through holes are machined according to the intervals of the screw holes of the frame body 41C, and then vinyl chloride is processed with the passage of time. The spacing between the through holes may be slightly narrowed by utilizing the shrinking property of the resin sheet. Alternatively, the vinyl chloride resin sheet used as the target plate 42C is formed with through holes at a high temperature, and then the vinyl chloride resin sheet shrinks as the temperature is returned to room temperature. It may be made slightly narrower.

With such a configuration, when the machine screws 53-6 and 53-7 are passed through the through holes of the target plate 42C and screwed into the screw holes of the frame body 41C, they are lowered at both ends of the lower side of the target plate 42C. The tension can be applied toward the outside of the side. As a result, in the target device 12C, the target plate 42C can be attached to the frame body 41C in a flat state so as to be substantially flat.

The gap between the frame body 41C and the target plate 42C may be prevented from coming into contact with the frame body 41C by using a material having adhesiveness on one side and difficult to transmit vibration, for example, a sponge tape or the like. Further, it may be attached with a sponge tape having adhesiveness on both sides, but in that case, the sponge tape needs to have a low density, softness and a certain thickness (for example, 2 mm or more). Further, when a sponge tape or the like having adhesiveness on both sides is used, the entire circumference of the target plate 42C may be attached to the frame 41C with the sponge tape without using machine screws.

The target device 12C configured in this way targets the machine screws 53-1 to 53-7 in a completely fixed state without loosening the machine screws as in the target device 12 of FIGS. 2 and 4. The plate 42C can be attached to the frame 41C. Even if the target plate 42C is attached to the frame 41C in this way, the target device 12C may be in a state of floating with a gap d with respect to the frame 41C on the left side, the right side, and the lower side of the target plate 42C. it can. However, loosening the machine screw has the effect of making it possible to detect even in the immediate vicinity of the screw.

As a result, the target device 12C can accurately detect the landing position where the BB bullet 32 has landed on the target plate 42 up to the vicinity of the left side, the right side, and the lower side of the target plate 42C. Therefore, for example, when the target device 12C is attached to the notebook PC 13 (see FIG. 4) and used, the landing position of the BB bullet 32 near the lower side of the display unit 22 of the notebook PC 13 can be accurately detected.

For example, as shown in FIG. 8 described above, when the target device 12A is attached to the display 81 and used, the display 81 can be used by using the target device 12A extending below the lower side of the display 81. It was possible to accurately detect the landing position of the BB bullet 32 near the lower side. On the other hand, as shown in FIG. 1 described above, when the target device 12 is attached to the notebook PC 13 and used, the main body 21 is located below the display unit 22 of the notebook PC 13, so that the display unit 22 of the notebook PC 13 is used. It was not possible to extend the target device 12 below the bottom edge.

On the other hand, since the target device 12C is in a state of floating with a gap d with respect to the frame body 41C at the lower side of the target plate 42C, even when the BB bullet 32 lands near the lower side of the frame body 41C, the target plate 42 can be sufficiently bent. Therefore, the target device 12C has high reproducibility of the impact sound generated when the BB bullet 32 lands near the lower side of the frame 41C, and the landing position can be accurately detected. Therefore, the target device 12C can set the detection range up to the upper end of the lower side of the frame 41C so that the landing position where the BB bullet 32 has landed on the target plate 42C can be accurately detected, and the landing position of the BB bullet 32 can be set. The detection performance can be improved.

Here, as the target device 12C is made smaller, it is required that the landing position of the BB bullet 32 can be detected more accurately to the vicinity of the end portion of the target plate 42C. On the other hand, when the target device 12C is small, it is not necessary to fix a plurality of upper sides of the target plate 42C to the frame 41C with machine screws 53 as described above, and both ends of the upper side of the target plate 42C. It is also necessary to fix these two places to the frame body 41C. That is, when the target device 12C is small, it is possible to adopt a configuration in which the four corners of the target plate 42C are fixed to the frame body 41C with the machine screws 53.

Further, the method of fixing the target plate 42C to the frame body 41C is not limited to the method using the machine screw 53, and as described above, at least a part thereof is loosely attached to the frame body 41C. If possible, various methods can be adopted. For example, an adhesive tape or the like is used so that the end portion of the sheet metal constituting the frame body 41C is bent inward so that the frame body 41C and the target plate 42C do not come into surface contact and the contact area is minimized. You may adopt a method of fixing the target plate 42C to the frame body 41C by utilizing the above. That is, when the BB bullet 32 lands on the target plate 42C, it is important to use a fixing method that can flexibly move to a portion as close to the end as possible of the target plate 42C.

In addition to the configuration in which the target system 11 of each of the above-described embodiments collects the BB bullets 32 using the collection tray 14, for example, a cloth having a predetermined thickness (for example, instead of the collection tray 14) is used. By arranging a microfiber towel), a configuration for collecting BB bullets 32 may be adopted. In addition, if the BB bullets 32 that land on the target plate 42 and fall can be collected without being scattered, the BB bullets 32 can be collected by various methods.

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. Further, the effects described in the present specification are merely examples and are not limited, and other effects may be obtained.
