If not calculated, the second measurement result is selected as the final result, and the predetermined period used by the selection section to select the second measurement result as the final result is the time during which the object goes around the competition course. It's relatively short .

[Overview of measurement system 100]
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing an example of a competition course 60 and a measurement point 65 in the embodiment.
In this example, the term "competition" refers to any competition in which athletes run around various courses and compete for finish by measuring the time required for the athletes to travel a predetermined distance. For example, the competitions in this example broadly include skating competitions such as speed skating, inline skating, and roller skating, track and field events, swimming, skiing, luge, and other competitions in which athletes go around various circuit courses. In addition, the competition in this example broadly includes bobsleigh, bicycle racing, motorcycle racing, automobile racing, etc. in which athletes compete for the finishing order of various vehicles. In addition, the competition in this example broadly includes competitions such as marathons in which athletes compete for the time it takes to travel from one point to another.
In this embodiment, an example in which the competition is speed skating will be described.

The competition course 60 is a course on which the athlete P runs. The competition course 60 may include an in-course 61 and an out-course 62. If the in-course 61 and out-course 62 are not distinguished, they will be referred to as a competition course 60.
Athlete P is a speed skating competitor. In the figure, a player P1 is running on an in-course 61, and a player P2 is running on an out-course 62. If player P1 and player P2 are not to be distinguished, they will be written as player P.
The measurement system 100 measures the time required for the player P to travel a predetermined distance (for example, one lap around the competition course 60) when the player P goes around the competition course 60.
The measurement point 65 is a point where the measurement system 100 measures the passage of the player P. The measurement system 100 detects that the player P passes the measurement point 65, and performs measurement based on the detected time.
Note that, depending on the event, when the player P1 running on the in-course 61 and the player P2 running on the out-course 62 intersect, the courses run by the respective players P may be switched. Even in this case, the measurement system 100 performs measurement based on the passage of the player P at the measurement point 65.

A first sensor and a second sensor are arranged at the measurement point 65. Each of the first sensor and the second sensor measures the passage of player P.
The first sensor has a narrower detection range and higher detection position accuracy than the second sensor. The second sensor has a wider detection range and lower detection position accuracy than the first sensor.
Here, the detection range refers to a spatial range in which the sensor can detect the player P. The detection range includes a spatial range in the direction in which the player P runs and a spatial range in the direction perpendicular to the competition course 60.
The detection position accuracy refers to the degree of deviation between the time when the player P actually passes the measurement point 65 and the time when the sensor detects the player P.

FIG. 2 is a diagram showing an example of measurement by the photosensor in the embodiment. An example of measurement using a photosensor will be described with reference to the same figure. The light emitting side sensor 71 and the PB detection sensor 7 are both sensors provided at the measurement point 65.
In this example, the light-emitting side sensor 71 is provided on the center line _CC between the in-course 61 and the out-course 62. The PB detection sensor 7a is placed on the extension line _CI in the figure. The PB detection sensor 7b is arranged on the outside line _CO in the figure.
Hereinafter, if the PB detection sensor 7a and the PB detection sensor 7b are not to be distinguished, they will be referred to as the PB detection sensor 7.

The light emitting side sensor 71 is installed on the ice surface 63 on the competition course 60, and emits (or projects; the same applies hereinafter) light of a predetermined wavelength toward the PB detection sensor 7a and the PB detection sensor 7b.
The PB detection sensor 7 is installed on the ice surface 63 similarly to the light-emitting sensor 71, and receives (or detects; the same applies hereinafter) a predetermined light emitted by the light-emitting sensor 71. The PB detection sensor 7 detects whether the player P has passed by depending on whether or not it receives a predetermined light. In this example, when the PB detection sensor 7 is installed at a point C1, the detectable range of the PB detection sensor 7 is defined as a detection range D1. In this case, the PB detection sensor 7 detects the player P when the player P exists in the detection range D1. Hereinafter, the PB detection sensor 7 will also be referred to as a first sensor. The PB detection sensor 7 is an example where the first sensor is a photosensor.
Note that the first sensor may be any sensor that has a narrower detection range and higher detection position accuracy than the second sensor, and is not limited to the example of a photosensor.

FIG. 3 is a diagram showing an example of measurement by the transponder in the embodiment. An example of measurement using a transponder will be described with reference to the same figure. The TP detection sensor 8 is a sensor provided at the measurement point 65.
In this example, player P wears transponder 80a on one foot and transponder 80b on the other foot. If the transponder 80a and the transponder 80b are not to be distinguished, they will be referred to as transponder 80. Specifically, the transponder 80 may be a passive tag (RFID chip) or the like that does not have a power source and is driven using externally supplied power.
Note that the transponder 80 is not limited to the example of a passive tag that does not have a power source, but may have a configuration in which the transponder 80 itself has a power source, such as an active tag, for example.

The TP detection sensor 8 is buried under the ice surface 63 on the competition course 60. The TP detection sensor 8 detects that the transponder 80 has passed through a predetermined range. When the TP detection sensor 8 is buried at the point C2, the range in which the TP detection sensor 8 can detect the transponder 80 is defined as a detection range D2. In this case, the TP detection sensor 8 detects the transponder 80 when the transponder 80 is present in the detection range D2. Hereinafter, the TP detection sensor 8 will also be referred to as a second sensor. The TP detection sensor 8 is an example of a case where the second sensor is an antenna that detects a transponder.
Since the TP detection sensor 8 is a sensor that detects radio waves, the detection range D2 of the TP detection sensor 8 is wider than the detection range D1 of the PB detection sensor 7 (first sensor), which is a photosensor. Furthermore, the detection position accuracy of the TP detection sensor 8 is lower than the detection position accuracy of the PB detection sensor 7 (first sensor).

The measurement point 65 where the PB detection sensor 7 and the TP detection sensor 8 are installed may be a finish line in a competition, or a lap line for measuring progress. The predetermined distance traveled by the player P measured by the measuring device 1 may be the distance from measurement point 65 to measurement point 65.
The starting point of the measurement may be the time when the player P passes the measurement point 65, or may be a gun signal from a starting pistol (not shown), or an electronic signal from a starting pistol (not shown).

[First embodiment]
FIG. 4 is a diagram showing an example of the functional configuration of the measurement system 100 in the first embodiment. The measurement system 100 will be explained with reference to the figure.
The measurement system 100 includes a PB detection sensor 7, a TP detection sensor 8, a measurement device 1, and a display device 41.

The PB detection sensor 7 is a photosensor provided at the measurement point 65 described in FIG. 2 . When the PB detection sensor 7 detects the passing of the player P, it outputs the detection result to the measuring device 1 as PB detection information _IPB1 .
The TP detection sensor 8 is an antenna that detects a signal emitted by a transponder provided at the measurement point 65, as described in FIG. When the TP detection sensor 8 detects passage of the player P wearing the transponder 80, the TP detection sensor 8 outputs the detection result to the measuring device 1 as TP detection information I _TP1 .
The measuring device 1 acquires PB detection information I _PB1 from the PB detection sensor 7 and TP detection information I _TP1 from the TP detection sensor 8, respectively. The measuring device 1 presents confirmed measurement information _IC on the display device 41 based on the acquired PB detection information _IPB1 and TP detection information _ITP1 .
The display device 41 acquires the final measurement information _IC from the measuring device 1 and displays the acquired final measurement information _IC . The display device 41 may be a display device such as a liquid crystal display or an LED display, for example.

The measuring device 1 includes a PB calculation section 10, a TP calculation section 20, a selection section 30, and a presentation section 40. Hereinafter, the PB calculation unit 10 will also be referred to as a first calculation unit, and the TP calculation unit 20 will also be referred to as a second calculation unit.

The PB calculation unit 10 includes a PB sensor information acquisition unit 11 and a PB calculation unit 12.
The PB sensor information acquisition unit 11 acquires PB detection information _IPB1 from the PB detection sensor 7. The PB sensor information acquisition unit 11 outputs the acquired PB detection information _IPB1 to the PB calculation unit 12.
The PB calculation section 12 includes a CPU 121, a storage section 122, and a timer counter 123. The PB calculation unit 12 calculates the time required for the player P to move a predetermined distance based on the acquired PB detection information _IPB1 . In this example, the predetermined distance is the distance traveled around the competition course 60 once. For example, when athlete P runs multiple laps around the competition course 60, each time the CPU 121 acquires the PB detection information I _PB1 , the CPU 121 stores the time when the PB detection information I _PB1 was acquired in the storage unit 122. By calculating the difference between the times stored in the section 122, the time required for the athlete P to travel a predetermined distance (in this case, one lap around the competition course 60) is calculated. The PB calculation unit 12 outputs the calculated result to the selection unit 30 as PB measurement information _IPB2 . PB measurement information I _PB2 is also described as a first measurement result.
That is, the PB calculation unit 10 (first calculation unit) calculates whether the object is within a predetermined distance (in this case, one lap around the competition course 60) based on the detection result of the passage of the object by the PB detection sensor 7 (first sensor). The time required for movement is calculated as PB measurement information _IPB2 (first measurement result).

The TP calculation unit 20 includes a TP sensor information acquisition unit 21 and a TP calculation unit 22.
The TP sensor information acquisition unit 21 acquires TP detection information I _TP1 from the TP detection sensor 8. The TP sensor information acquisition section 21 outputs the acquired TP detection information I _TP1 to the TP calculation section 22.
The TP calculation section 22 includes a CPU 221, a storage section 222, and a timer counter 223. The TP calculation unit 22 calculates the time required for the player P to move a predetermined distance based on the acquired TP detection information I _TP1 . For example, when athlete P runs multiple laps around the competition course 60, each time the CPU 221 acquires the TP detection information I _TP1 , the CPU 221 causes the storage unit 222 to store the time at which the TP detection information I _TP1 was acquired. By calculating the difference between the times stored in the section 222, the time required for the athlete P to travel a predetermined distance (in this case, one lap around the competition course 60) is calculated. The TP calculation unit 22 outputs the calculated result to the selection unit 30 as TP measurement information I _TP2 . TP measurement information I _TP2 is also described as a second measurement result.
In other words, the TP calculation unit 20 (second calculation unit) calculates whether the transponder 80 (identification device) attached to the object passes by the TP detection sensor 8 (second sensor). The time required for moving a predetermined distance (one lap around the competition course 60 in this case) is calculated as TP measurement information I _TP2 (second measurement result).

The selection unit 30 acquires PB measurement information I _PB2 from the PB calculation unit 10 and acquires TP measurement information I _TP2 from the TP calculation unit 20. The selection unit 30 selects one of the acquired PB measurement information I _PB2 (first measurement result) or TP measurement information I _TP2 (second measurement result) as the final measurement information I _C (determined result), It is output to the presentation section 40.
Specifically, the selection unit 30 makes the selection based on whether the PB measurement information _IPB2 (first measurement result) has been calculated by the PB calculation unit 10 (first calculation unit). More specifically, when the PB calculation unit 10 (first calculation unit) calculates the PB measurement information I _PB2 (first measurement result), the selection unit 30 selects the PB measurement information I _PB2 (first measurement result). result) is selected as the final measurement information I _C (final result) and output to the presentation unit 40.

The presentation unit 40 causes the display device 41 to display the acquired confirmed measurement information _IC . That is, the presentation unit 40 presents the final measurement information I _C (final result) selected by the selection unit 30.
Note that the presentation unit 40 and the display device 41 may be connected by wire or by predetermined wireless communication.

Here, the PB detection sensor 7 has a narrower detection range than the TP detection sensor 8, and has higher detection position accuracy than the TP detection sensor 8. Since the PB detection sensor 7 has high detection position accuracy, the selection unit 30 preferentially selects the measurement result by the PB detection sensor 7.
On the other hand, since the PB detection sensor 7 has a narrow detection range, it may not be possible to detect the passing of the player P, for example, if the player jumps over the detection range D1 of the PB detection sensor 7. When the PB detection sensor 7 does not measure, the selection unit 30 selects the measurement result by the TP detection sensor 8.
Hereinafter, the failure to obtain a measurement result by the PB detection sensor 7 due to the inability to detect the passing of the player P due to the player jumping over the detection range D1 of the PB detection sensor 7 will be referred to as a measurement error.

FIG. 5 is a diagram showing an example of a series of operations of the measuring device 1 in the first embodiment. A series of operations of the measuring device 1 will be described with reference to the same figure.
(Step S12) The measuring device 1 acquires the detection result. When the PB detection sensor 7 detects the passing of the player P, it outputs PB detection information _IPB1 . When the PB calculation unit 10 acquires the PB detection information I _PB1 (that is, step S12; YES), the process advances to step S16. When the TP detection sensor 8 detects the signal emitted by the transponder 80, it outputs TP detection information I _TP1 . When the TP calculation unit 20 acquires the TP detection information I _TP1 (that is, step S12; NO), the process advances to step S14.

(Step S14) If the PB detection sensor acquires the PB detection information I _PB1 within a predetermined period after the TP calculation unit 20 acquires the TP detection information I _TP1 (that is, Step S14; YES), the process Proceed to step S16. If the PB detection sensor does not acquire the PB detection information I _PB1 within a predetermined period after the TP calculation unit 20 acquires the TP detection information I _TP1 , that is, the PB detection sensor 7 has made a measurement error, and the TP detection sensor If only player P 8 is detected passing by player P (that is, step S14; NO), the process advances to step S18. Here, the predetermined period may be determined based on the time during which the athlete P goes around the competition course 60. The predetermined period is shorter than the time during which the athlete P goes around the competition course 60. For example, the predetermined period is 5 seconds.

(Step S16) The selection unit 30 selects the PB measurement information _IPB2 as the final measurement information _IC . The selection unit 30 outputs the confirmed measurement information _IC to the presentation unit 40, and ends the process.
(Step S18) The selection unit 30 selects the TP measurement information I _TP2 as the final measurement information I _C. The selection unit 30 outputs the confirmed measurement information _IC to the presentation unit 40, and ends the process.

[Second embodiment]
FIG. 6 is a diagram showing an example of the functional configuration of the measurement system 100A in the second embodiment. The measurement system 100A will be explained with reference to the figure. The measurement system 100A is an example of the measurement system 100. The measuring device 1A is an example of the measuring device 1.
The measurement system 100A in the second embodiment differs from the measurement system 100 in that it further includes a PB permission selection device 75 and a TP non-detection time storage section 85.
The PB calculation unit 10A differs from the PB calculation unit 10 in that it further includes a PB permission switch 13.
The TP calculation unit 20A differs from the TP calculation unit 20 in that it further includes a TP permission switch 23.
Hereinafter, those having the same functions as those provided in the measuring device 1 will be designated by the same reference numerals as in FIG. 4, and a description thereof will be omitted.

The PB permission selection device 75 is a device that selects whether or not to treat the output of the PB detection sensor 7 effectively. For example, the PB permission selection device 75 is an input device such as a push button switch operated by an operator.
Here, when a plurality of players P pass at the same time, the photosensor may not be able to distinguish and determine each player P. In an example where the PB detection sensor 7 is a photo sensor, depending on the competition, if a plurality of athletes P pass through one course at the same time, the PB detection sensor 7 may not be able to accurately measure the time at which the athletes P pass. be.
For example, in speed skating, when a plurality of athletes pass the PB detection sensor 7 at the same time, the PB detection sensor 7 may not be able to detect the passage of each athlete.
When the PB permission selection device 75 is selected, the PB permission selection device 75 outputs information indicating that the PB permission selection device 75 has been selected as the PB permission information _IPBE to the measurement device 1.
The measurement system 100A treats the output of the PB detection sensor 7 as invalid when the PB permission selection device 75 is selected.

The PB permission switch 13 is connected between the PB sensor information acquisition section 11 and the PB calculation section 12, and switches the connection state between the PB sensor information acquisition section 11 and the PB calculation section 12. Specifically, when the PB permission switch 13 is in the on state, the PB detection information _IPB1 can be output from the PB sensor information acquisition section 11 to the PB calculation section 12. When the PB permission switch 13 is in the off state, the PB detection information _IPB1 is not output from the PB sensor information acquisition section 11 to the PB calculation section 12.
When the PB permission switch 13 is in the on state, the PB calculation unit 12 is in a state where it can acquire the PB detection information I _PB1 , so the PB calculation unit 10A calculates the PB measurement information I _PB2 . A state in which the PB calculation unit 10A can calculate the PB measurement information _IPB2 is described as a valid state. When the PB permission switch 13 is in the OFF state, the PB calculation unit 12 cannot obtain the PB detection information _IPB1 , so the PB calculation unit 10A does not calculate the PB measurement information _IPB2 . A state in which the PB calculation unit 10A is unable to calculate the PB measurement information _IPB2 is referred to as an invalid state.
In other words, the PB permission switch 13 (first switching section) is in an enabled state in which the PB calculation section 10A (first calculation section) calculates PB measurement information I _PB2 (first measurement result), and a valid state in which the PB calculation section 10A (first calculation section) calculates the PB measurement information I PB2 (first measurement result). (calculating section) switches between an invalid state in which the PB measurement information I _PB2 (first measurement result) is not calculated.
The on state and off state of the PB permission switch 13 are controlled by a PB permission selection device 75.
Note that the PB permission switch 13 may be configured by hardware or may be realized by software.

The TP non-detection time storage unit 85 is a storage unit that stores a TP non-detection time that determines whether or not the output of the TP detection sensor 8 is treated effectively.
Here, it is desirable that the TP detection sensor 8 be disabled except at the timing when the player P is predicted to pass the measurement point 65. If the TP detection sensor 8 is enabled at a time other than when the player P is predicted to pass the measurement point 65, the TP detection sensor 8 may make a false detection. Therefore, by disabling the TP detection sensor 8 at a timing other than the timing when the player P passes the measurement point 65, false detection can be suppressed.
For example, in a competition such as speed skating in which an athlete P goes around a competition course 60, the time from when the athlete P passes the measurement point 65 until the next time the same athlete P passes the measurement point 65 is predicted. can do. In this example, by storing in the TP non-detection time storage unit 85 the estimated time (predetermined time) required for the athlete P to go around the competition course 60, the measuring device 1A The TP detection sensor 8 is disabled for a predetermined time stored in the TP non-detection time storage section 85 after passing the measurement point 65.

The TP permission switch 23 is connected between the TP sensor information acquisition section 21 and the TP calculation section 22, and switches the connection state between the TP sensor information acquisition section 21 and the TP calculation section 22. Specifically, when the TP permission switch 23 is in the on state, the TP detection information I _TP1 can be output from the TP sensor information acquisition section 21 to the TP calculation section 22. When the TP permission switch 23 is in the off state, the TP detection information I _TP1 is not output from the TP sensor information acquisition section 21 to the TP calculation section 22.
When the TP permission switch 23 is in the on state, the TP calculation section 22 can acquire the TP detection information I _TP1 , so the TP calculation section 20A can calculate the TP measurement information I _TP2 . A state in which the TP calculation unit 20A can calculate the TP measurement information I _TP2 is referred to as a valid state. When the TP permission switch 23 is in the off state, the TP calculation unit 22 cannot acquire the TP detection information I _TP1 , and therefore the TP calculation unit 20A cannot calculate the TP measurement information I _TP2 . A state in which the TP calculation unit 20A is unable to calculate the TP measurement information I _TP2 is referred to as an invalid state.
In other words, the TP permission switch 23 (second switching section) is in an enabled state in which the TP calculation section 20A (first calculation section) calculates the TP measurement information I _TP2 (second measurement result), and in a valid state in which the TP calculation section 20A (second measurement result) is calculated. (calculation unit) does not calculate the TP measurement information I _TP2 (second measurement result).
The time period during which the TP permission switch 23 continues to maintain the off state after detecting the TP measurement information I _TP2 is determined by a predetermined time period stored in the TP non-detection time storage section 85. The TP permission switch 23 acquires a predetermined time period during which the off state is maintained from the TP non-detection time storage unit 85 as TP permission information I _TPE .
Note that the TP permission switch 23 may be configured by hardware or may be realized by software.

[Third embodiment]
FIG. 7 is a diagram showing an example of the functional configuration of a measurement system 100B in the third embodiment. The measurement system 100B will be explained with reference to the figure. Measurement system 100B is an example of measurement system 100. The measuring device 1B is an example of the measuring device 1.
The measuring device 1B in the third embodiment further includes an estimation section 50.

The estimation unit 50 estimates the time it takes for the player P to pass the measurement point 65.
Here, the PB permission selection device 75 is operated by the operator. The operator visually recognizes in which part of the competition course 60 the player P is running, and when the player P approaches the measurement point 65, operates the PB permission selection device 75. In this embodiment, by providing the estimation unit 50, the timing at which the player P passes the measurement point 65 is predicted and outputted to the presentation unit 40.

The estimation unit 50 acquires TP measurement information I _TP2 from the TP calculation unit 20. The estimation unit 50 predicts the timing (time) when the player P passes the measurement point 65 based on the TP measurement information I _TP2 (second measurement result) calculated by the acquired TP calculation unit 20 (second calculation unit). . The timing at which the player P passes the measurement point 65 is the timing at which the PB detection sensor 7 (first sensor) passes the player P (object). The estimation unit 50 outputs the predicted timing at which the player P passes the measurement point 65 to the presentation unit 40 as estimated measurement information _IET .

The presentation unit 40 acquires the estimated measurement information _IET from the estimation unit 50. The presentation unit 40 causes the display device 41 to display information indicating the time indicated in the acquired estimated measurement information _IET .
Note that the display performed by the display device 41 is not limited to the example of displaying the timing of passing the measurement point 65, and may be configured to notify by countdown until the timing of passing the measurement point 65. For example, the display device 41 performs a countdown starting 10 seconds before the predicted timing when the player P passes the measurement point 65. The operator can operate the PB permission selection device 75 based on the countdown on the display device 41 and the actual competition situation.

Note that the display performed by the display device 41 is not limited to the example of the countdown notification described above, but may also be a notification method using text information such as "The athlete will pass soon." or "The athlete will pass soon." The notification method may be a notification method in which the player P reads out aloud, or a notification method using sound information such as a buzzer on sound, or information consisting of colors (for example, each time athlete P approaches the measurement point 65, the color changes from green to orange to red. The notification method may also be by displaying a message (such as a change in the name).

Note that instead of the predetermined time stored in the TP non-detection time storage section 85, the estimated measurement information _IET estimated by the estimation section 50 is used to control the on state and off state of the TP permission switch 23. may be configured. With this configuration, the TP permission switch 23 can be controlled at a predetermined time period that matches the competition.

[Summary of effects of embodiment]
As described above, the measuring device 1 of the present embodiment includes the PB calculating section 10 and the TP calculating section 20, thereby acquiring the PB detection information I _PB1 from the PB detecting sensor 7, and acquiring the PB detection information I PB1 from the TP detecting sensor 8. Obtain TP detection information I _TP1 . The measuring device 1 includes the selection unit 30 to select either the measurement result based on the PB detection sensor 7 or the measurement result based on the TP detection sensor 8.
When the measurement result is calculated by the PB detection sensor 7, the selection unit 30 preferentially outputs the PB measurement information _IPB2 , which is the measurement result by the PB detection sensor 7, as the final measurement information _IC . In other words, by preferentially selecting the measurement results based on the PB calculation section 10, the selection section 30 can preferentially use the measurement results obtained by the PB detection sensor 7 having high detection position accuracy. Furthermore, even when the PB detection sensor 7 is unable to perform measurement, the selection unit 30 can use the measurement results obtained by the TP detection sensor 8 .
Therefore, according to the measuring device 1 of the present embodiment, the measurement result by the PB detection sensor 7 can be used preferentially, and if the measurement result is not performed by the PB detection sensor 7, the measurement result by the TP detection sensor 8 can be used. can be used.

Furthermore, the measuring device 1 of this embodiment further includes a PB permission switch 13. The measuring device 1 switches the connection state of the PB permission switch 13 when the PB permission selection device 75 is operated. The PB permission selection device 75 is operated in the case of a crowded race (such as when a plurality of players cross the measurement point 65 at the same time). The measuring device 1 controls the connection state of the PB permission switch 13 to a disconnected state when the PB permission selection device 75 is operated.
Therefore, according to the measuring device 1 of the present embodiment, by providing the PB permission switch 13, it is possible to not use the measurement results by the PB detection sensor 7 in a melee situation.

Furthermore, the measuring device 1 of this embodiment further includes a TP permission switch 23. The measuring device 1 switches the connection state of the TP permission switch 23 based on the predetermined time stored in the TP non-detection time storage section 85. The predetermined time stored in the TP non-detection time storage section 85 is the timing at which the player P is predicted to pass the measurement point 65. The TP permission switch 23 is controlled to be in a disconnected state at timings other than when the player P is predicted to pass the measurement point 65.
Therefore, according to the measuring device 1 of this embodiment, by providing the TP permission switch 23, a predetermined non-detection time can be provided. Therefore, the measuring device 1 can eliminate the influence of noise at the timing when the TP detection sensor 8 does not perform measurement.

Moreover, the measuring device 1 of this embodiment further includes an estimating section 50. The estimation unit 50 predicts the timing when the player P passes the measurement point 65 and outputs the prediction to the presentation unit 40. The presentation unit 40 displays the timing at which the player P passes the measurement point 65 using a predetermined method.
Therefore, according to the measuring device 1 of this embodiment, by including the estimation unit 50, the operator can be notified of the timing at which the player P passes the measurement point 65.

Although the mode for implementing the present invention has been described above using embodiments, the present invention is not limited to these embodiments in any way, and various modifications and substitutions can be made without departing from the spirit of the present invention. can be added.
