When the internal power source is a rechargeable battery, it is desirable that the external connection unit 17 can be used as a charging port for supplying electricity to the rechargeable battery.

  The actual hit detection unit 15 detects whether or not the golf player wearing the measuring device body 1 swings, and whether or not the golf player's arm has an impact. And an impact detection unit 15B.

  The swing detection unit 15A includes a geomagnetic sensor for detecting the attitude (orientation) of the measuring device main body 1 and an acceleration sensor for detecting the acceleration (centrifugal force and rotational force) of the measuring device main body 1.

The swing detector 15A transmits information (data) on the posture change of the measuring device main body 1 and information on the acceleration change of the measuring device main body 1 to the processing unit 12.
The processing unit 12 detects the swing motion by comparing the posture change information and the acceleration change information with the swing reference information (range value, threshold value, etc.) stored in advance in the storage unit 14 (swing detection process).

  Here, as shown in FIG. 3, the measurement when the golf player wearing the measuring instrument main body 1 (hereinafter sometimes referred to as a player) swings up the golf club from the state of swinging up as shown in FIG. The storage unit 14 stores in advance information on standard (average) posture changes and acceleration changes of the main body 1 as swing reference information.

  The processing unit 12 and the swing reference information may be any one or more of a backswing until the golf club is swung up, a downswing until the golf club is swung up, and a follow swing after the swinging down. What is necessary is just to provide so that the state of the combined swing may be detected.

The impact detection unit 15B includes an acceleration sensor for detecting an impact based on a change in acceleration of the measuring device main body 1.
This acceleration sensor is used in combination with the acceleration sensor of the swing detection unit 15A.

The impact detection unit 15B transmits information on the acceleration change of the measuring instrument main body 1 to the processing unit 12.
The processing unit 12 detects the impact by comparing the received acceleration change information with the impact reference information (range value and threshold value) stored in advance in the storage unit 14 (impact detection processing).
The storage unit 14 stores in advance, as shock reference information, information on standard (average) acceleration change when a ball is hit with a golf club (driver, iron, or the like) appropriately.

  As shown in FIG. 6, the processing unit 12 performs a swing / impact detection process after the measuring instrument body 1 is turned on. Thereafter, it is confirmed whether or not an impact is detected in the first step S1 (impact confirmation processing).

If an impact is detected in the first step S1, the process proceeds to the second step S2, and information on the position (impact position) at which the impact was received and information on the time at which the impact was received are stored in association with each other. Store in part 14.
When the impact is not detected in the first step S1, the process proceeds to the third step S3 to check whether or not a swing is detected (swing confirmation process).

  If the swing is detected in the third step S3, the process proceeds to the next fourth step S4, where the information on the position where the swing was made (swing position) and the information on the time when the swing was made are stored in association with each other. Store in part 14.

In the fifth step S5 after the second step S2 or the fourth step S4, a movement confirmation process is performed.
In the movement confirmation process, an impact position or a swing position associated with a time closest to the current time (closest to the time when the movement confirmation process is performed) is set as a reference position, and within a predetermined time, a predetermined value is set from the reference position. Whether or not the vehicle has moved beyond a distance (for example, 10 m) is calculated by checking the current position and the moving distance.

If the player has moved in the fifth step S5, the process proceeds to the next sixth step S6.
If the player has not moved beyond the predetermined distance within the predetermined time, the process returns to the swing / impact detection process. Further, when a swing or impact is detected within the predetermined time, it has not moved beyond a predetermined distance (the player exists within a circle range centered on the reference position and having a predetermined distance as a diameter). Determine and return to the first step S1 (impact confirmation process).

The player often performs swinging before actually hitting the golf ball. In swinging, the swing is detected and the impact is not detected. Therefore, the process proceeds through the first step S1, the third step S3, the fourth step S4, and the fifth step S5.
And since it is a swing and the ball is not flying, if the golf player does not move beyond a predetermined distance within a predetermined time, the process returns to the swing / impact detection process (swing path), and the ball is hit within the predetermined time. When swing / impact is detected, the process returns to the impact confirmation process (swinging route).
In addition, the player may perform a plurality of swings before hitting, but the above-described swing route is repeated for each swing. In addition, the same processing route is used for idling.

  After swinging, if the player hits the ball appropriately as shown in FIGS. 3 to 4, swing and impact are detected. The processing route of the first step S1, the second step S2, and the fifth step S5 is passed. Since the ball flew, the golf player moves beyond a predetermined distance, and proceeds from the fifth step S5 to the sixth step S6.

As described above, when the ball is hit appropriately after swinging, the storage unit 14 stores information on the swing position when swinging, the swing position when hitting the ball appropriately, and the impact position.
In the sixth step S6, the information on the impact position in the storage unit 14 is confirmed, and the process proceeds to the next seventh step S7, where the information on the impact position when the ball at the latest time is hit is obtained as the actual hit position ( And is stored in the storage unit 14.

  Also, if the golf player hits after swinging and the club rolls over the top of the ball and the ball rolls (in the case of a miss shot generally called choro or top), the swing is detected, but the impact May be too small to be detected. Accordingly, the processing route of the first step S1, the third step S3, the fourth step S4, and the fifth step S5 is passed. Since the ball has rolled, the golf player moves beyond a predetermined distance and proceeds from the fifth step S5 to the sixth step S6.

When the ball has advanced by a miss shot called choro or top after swinging, the storage unit 14 stores the swing position for swing and the swing position for miss shot.
In the sixth step S6, there is no information on the impact position, and in the next eighth step S8, there is information on the swing position. Of the information on the plurality of swing positions, the latest information is obtained in the ninth step S9. The swing position in the case of the miss shot at the time is determined as the actual hit position and stored in the storage unit 14.

If the golf player hits the ball after swinging and hits the ground as shown in FIG. 5 and the ball does not fly (generally referred to as duffing), both swing and impact are detected, The processing route of the first step S1, the second step S2, and the fifth step S5 is passed. Since the ball is not flying, the player does not move beyond the predetermined distance, and the process returns from the fifth step S5 to the swing / impact detection process or the impact confirmation process.
If the ball flies even if it is duffed, the player moves beyond a predetermined distance, and therefore proceeds to sixth step S6 and seventh step S7.

If the ball is properly hit after swinging and duffing, the storage unit 14 stores the swing position for swinging, the swing position and impact position for duffing, and the swing for properly hitting the ball. The position and the impact position are stored.
In the sixth step S6, the information on the impact position is confirmed in the storage unit 14, and the process proceeds to the next seventh step S7, and the latest time among the information on the plurality of impact positions is associated (the ball is appropriately selected). The impact position at the time of hitting is determined as the actual hitting position and stored in the storage unit.

In addition, if the ball moves with a miss shot called choro or top after a swing, the storage unit 14 stores the swing position for swing, the swing position and the impact position for a duff, and the miss. The swing position in the case of a shot is stored in the storage unit 14.
In the sixth step S6, the information on the impact position is confirmed in the storage unit 14, and the process proceeds to the next seventh step S7, where the impact position of the duffing with which the latest time is associated (the ball did not fly) is realized. It is determined as the hitting position.
The impact position of the duffing where the ball did not fly is equal to the position where the ball was actually struck (the position where the missed shot was made), so there is no adverse effect on the measurement of the moving distance and the ball flying distance described later. There is no problem even if the position is determined.

  In this way, until the player moves beyond a predetermined distance, the swing position in the case of swinging, the swing position in the case of swinging, the swing position in the case of a miss shot called choro or top, the swing position in the case of duffing, and the like A plurality of various types of position information (data) such as the impact position and the swing position and impact position when the ball is hit appropriately are stored in the storage unit 14, but if there is information on the impact position, Processing is performed so that the impact position is preferentially adopted as the actual hitting position. Furthermore, the impact position associated with the latest time (time data closest to the time when the process for determining the actual hit position is started) is selected as the actual hit position from a plurality of impact positions. To do. When there is no information on the impact position, the swing position associated with the latest time is determined (adopted) from among the information on the plurality of swing positions.

  The actual hit position is recorded (stored) at the ball position by the processing unit 12, the actual hit detection unit 15 and the storage unit 14 without manual operation of the operation unit 16 by the player (determination of the actual hit position is a trigger). Done automatically. After the actual hitting position is determined, information on other impact positions and swing positions that have not been adopted is deleted.

Here, although not shown, when the actual hit position is determined, the processing unit 12 measures a moving distance (linear distance) from the actual hit position to the current position of the player. The player starts automatically without manually operating the operation unit 16.
Further, the measured distance is displayed as the ball flight distance information hit from the actual hitting position on the display unit 13 automatically in real time (results measured every predetermined time) without manual operation of the operation unit 16 by the player. Let
When the player arrives at the ball arrival point, the flying distance of the ball can be grasped by visually recognizing the display unit 13.

When the player arrives at the ball arrival point and swings before hitting the second shot or performs the action of hitting the second shot, as shown in FIGS. A hit position determination process (actual hit position determination process of the second hit) is performed.
Note that * 1 in FIG. 6 is connected to * 1 in FIG. 7, and * 2 in FIG. 7 is connected to * 2 in FIG.

  As shown in FIG. 7, after the processing unit 12 determines a new actual hit position (after the second hit actual hit position determination process), the distance (first step) from the previous actual hit position to the new actual hit position. The straight hit position from the actual hit position of the first hit to the actual hit position of the second hit without the player manually operating the operation unit 16 (the actual hit position without receiving a command from the operation unit 16) The calculation (measurement) starts automatically (using the determination of) as a trigger, and the distance is stored in the storage unit 14 as the ball flight distance information of the first shot (flight distance storage processing). The ball flight distance information is stored in association with the order information.

Although not shown, when the actual hitting position of the second hit is determined, the processing unit 12 automatically starts measuring (calculating) the moving distance from the actual hitting position to the current position of the player, and the measurement is performed. The distance is displayed on the display unit 13 in real time (every predetermined time) as the ball flight distance information of the second shot.
When the player arrives at the ball arrival point for the second shot, the distance of the second hit ball can be grasped by viewing the display unit 13.

  Thereafter, an actual hit position determination process for the third hit is performed, and then a flight distance storage process for the second hit is performed. That is, until a predetermined end operation is performed by the operation unit 16, the actual hitting position is determined and stored (actual hitting position determining process), the ball flight distance (moving distance from the actual hitting position) is displayed in real time, The storage of the flight distance (the flight distance storage process) is repeated automatically (even if the player does not manually operate the operation unit 16).

  After the golf play is finished, the ball flight distance information stored in the storage unit 14 is connected to an external device such as a personal computer or a smartphone via the external connection unit 17, and the ball flight distance information is stored. Reading, ball flight distance information, and the club number at the time of hitting the ball can be linked (linked), contributing to data collection and analysis of the flight distance for each club number.

  In the present invention, the design can be changed, and the flight distance storing process does not have to be performed between the actual hit position determination process and the next actual hit position determination process. You may do it all together. The operation unit 16 may be a touch panel type corresponding to the display unit 13. The time information (data) may be information including date information (data) such as a date as well as hours, minutes, and seconds. The unit of the displayed distance may be either yard or meter. The numerals “S1” and “S9” of the names of the steps, such as “S1” and “S9”, are given for ease of explanation and do not mean the order of processing. No.

  As described above, the flight distance measuring device of the present invention includes the measuring device main body 1 attached to the golf player's arm, and the measuring device main body 1 can calculate the position of the golf player based on the radio wave from the positioning satellite. A processing unit 12, an actual hit detection unit 15 for detecting whether or not the golf player has hit the ball, and a storage unit 14 for storing the hit position as the actual hit position. When the actual hit detection unit 15 detects that the ball has been hit, the actual hit position is determined, and the distance from the previous actual hit position to the new actual hit position is calculated as the ball flight distance. Since the storage unit 14 stores the flight distance, it is not necessary for the golf player to manually operate the operation button to measure the flight distance during golf play, and the flight distance can be reliably measured and recorded (stored). , Reduce the burden on golf players, It can be concentrated to Rufupurei. Further, the golf play can be smoothly advanced.

  Further, the actual hit detection unit 15 includes a swing detection unit 15A for detecting whether or not the golf player has made a swing, an impact detection unit 15B for detecting whether or not the golf player's arm has an impact, The processing unit 12 stores the swing position detected by the swing detection unit 15A in the storage unit 14 in association with the time, and stores the impact position detected in the impact detection unit 15B in association with the time. When the golf player moves beyond a predetermined distance from the swing position or the impact position, the impact position at the most recent time among the swing position and the impact position stored in the storage unit 14 is set as the actual hit position. Since the position information is determined, it is possible to exclude the position information of the swinging motion and the swinging motion, and to record (store) the accurate ball flight distance. Further, even in the case of a miss shot such as choro or top where the impact cannot be detected, the position information on the ball can be obtained, and the ball flight distance can be stored reliably.

  Further, since the swing detection unit 15A includes a geomagnetic sensor and an acceleration sensor, and the impact detection unit 15B includes an acceleration sensor, the swing and the impact can be reliably detected, and the measuring instrument main body 1 can be easily made lightweight, small and easy (inexpensive). ) Can be manufactured.
