DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing the overall configuration of a golf simulation device 1 according to the present invention, and FIG. 2 is a sectional view thereof.

A rubber plate 5 is covered on the upper surface of the flat base 2, and a tee 7 is inserted in the front portion of the rubber plate 5. A plurality of sensor rows-four sensor rows 6a to 6d in this embodiment-are arranged on the rubber plate 5 in a direction orthogonal to the direction in which the golf club is swung.
Are arranged at predetermined intervals. Each sensor row is composed of a light emitting section and a light receiving section that receives reflected light from the club head that has been emitted from the light emitting section and that has passed through the set, and a large number of sets are arranged in a straight line. As shown in FIG. 2, each sensor row is provided on a substrate 10 arranged on a bottom plate 2a of the base 2, and this substrate is provided with holes 5a to 5d for sensor rows formed on the rubber plate 5. The rows 6a to 6d are aligned with each other.

On the bottom plate 2a, there are provided a power source 15 and a control section 20 for arithmetically processing the club head information obtained by each sensor array and outputting the processed signal to the display device 70. The configuration of this control unit will be described with reference to the block diagram of FIG. The control unit 20 has a CPU 21,
The CPU 21 is connected to an operating means 27 connected to a main switch 25 for turning on / off the power supply 15. The operating means 27 activates the CPU only when the user performs some operation from the outside. In this embodiment, the operating means is an impact sound given from the outside, that is, the user actually The impact sound detection circuit detects an impact sound generated when the rubber plate 5 is struck by the club head immediately before the swing.

The output side of the CPU 21 has a holding circuit 2 which holds the starting state of the CPU 21 based on a signal from the operating means 27.
9 is connected to the input side, and when the holding circuit 29 is turned on, the operating means 27 is turned off. In addition, the CPU 21
Is connected to the sensor circuit 30 and causes the light emitting portion to emit light when in the activated state, and captures the detection signal by the reflected light from the club head.

Next, the impact sound detecting circuit which is the operating means 27 will be described with reference to FIG. The impact sound detection circuit has a microphone 50.
BPF that passes only the frequency corresponding to the impact sound
It is connected to (Band pass filter). The signal corresponding to the frequency of the impact sound that has passed through the BPF is amplified by the amplifier circuit, and then the diode D, the capacitor C, and the resistor R.
The signal is smoothed by 1 to extract the DC component, which is input to the base of the transistor Tr1. The collector of Tr1 is connected to the base of the transistor Tr2, and when the transistor Tr1 detects an impact sound and turns on, the transistor Tr2 turns on. That is, the transistor T
r2 is turned on only during the time when the impact sound is generated when the rubber plate is hit with the club head.

In the present embodiment, the above-mentioned main switch 25 is composed of a horizontal detection switch. This is because in the case of a normal switch, it is unnecessarily turned on when the device is housed, and power consumption is prevented by erroneous operation. That is, the power supply 15 is turned on only when the simulation device is actually used (horizontal position).
In the state of being stored (vertical state), it is always in the OFF state. FIG. 5 shows an example of a specific configuration of the horizontal position detection switch. As shown in (a), a hole 53 is formed in a housing 52 in which a sphere 57 is arranged in an internal space, a swinging member 55 is inserted, and a biasing member 56 is biased. When the housing 52 is in the horizontal state, the sphere 57 falls from the state shown by the dotted line to the concave portion in the internal space, as shown by the solid line,
The swinging member 55 is pushed in against the biasing force of the biasing member. At this time, the rocking member 55 pushed in turns on the switch. That is, the switch is turned on when it becomes horizontal.
In other states, the ball 57 becomes as shown by the dotted line, and the switch is turned off by the urging force acting on the swing member.
Becomes Alternatively, as shown in (b), a pair of electrodes 60, which are switches, and a mercury 6, which is a conductive member, are provided in the housing 52.
Arrange 3 and. When the casing is in the horizontal state, the state of the mercury 63 is changed from the state indicated by the dotted line to the state indicated by the solid line, and the switch is in the ON state. Further, when the housing tilts, mercury also tilts, the connection of the electrode 60 is cut off, and the switch is turned off.

Referring to the flow chart of FIG. 6, the operation of the golf simulation apparatus 1 configured as described above, that is, a series of flow in which the user swings and the result is displayed on the display section 70a of the display apparatus 70, will be described. Explain.

First, a battery serving as a power source of the golf simulation device 1 is inserted. When actually using the device,
The device (base 2) is placed horizontally. At this time, the horizontal detection switch 25, which is the main switch, is turned on. With this configuration, the main switch does not turn on until the simulation device is in use (S1). Of course, the main switch may be of a normal manual operation type.

Next, the user gives a predetermined operation to the operation means 27 immediately before detecting the actual swing. In this embodiment, the club head hits the rubber plate 5. The impact sound when hitting the rubber plate 5 with the club head is picked up by the microphone 50, and the impact sound causes C
The PU 21 is activated. In this case, although there are various sounds picked up by the microphone, only the impact sound of the club head is detected by the impact sound detection circuit shown in FIG. 4 (S2). While the impact sound is generated, Tr2 is turned on and the CPU 21 is activated at the same time as this ON signal. In this case, if the impact sound signal is not input to the CPU 21 for a predetermined time t1 or longer, the CPU 21 does not enter the activated state (S3).

When an impact sound signal of a predetermined time t1 or more is input and the CPU 21 is activated, the holding circuit 29 is turned on and the impact sound detection circuit is turned off (S4). When the holding circuit 29 is turned on, the CPU 21 keeps the activated state, and the light emitting section of the sensor array is turned on.
Wait for the club head to pass. In this state, if the club head does not pass the sensor row within the predetermined time t2 (for example, about 15 seconds), the holding circuit 29 is turned off (S5, S1).
0) and the activation state of the CPU 21 is cut off. And
Again, it waits in a state where the impact sound is detected (S1, S
2).

Each of the sensor rows 6a to 6d waits for the club head to pass within the predetermined time (S6). When each sensor detects the club head passage, the detection signal is C.
It is input to the PU 21. Then, the CPU 21 performs pattern processing and calculation of the club face based on the input signal, and outputs signals such as head speed, position, and tilt to the display device 70 (S7, S8). Then, on the display unit 70a of the display device, for example, as shown in the drawing, the state of the club face in each sensor row is displayed (S9). After this display is done for a predetermined time,
The holding circuit 29 is turned off (S10), and the activation state of the CPU 21 is cut off. Then, in order to measure the next swing again, the process waits in a state of detecting an impact sound (S1, S
2).

As described above, the CPU is activated and the light emitting portion of the sensor row is turned on only when the user hits the rubber plate 5 with the club head, so that the power consumption can be reduced. In addition, by configuring the main switch to be turned on in the normal use state by the horizontal position detection switch shown in FIG. 5, the main switch is turned on when not in use.
Then, it does not consume useless power.

When the golf simulation apparatus of this embodiment is actually used, in the process shown in the flowchart of FIG. 6, the current consumption in S1 is 0 A, the current consumption in S2 is 1 μA, and the consumption up to S3 to S10. Current is 5-30
mA and a considerable power savings was achieved.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made as described below. The number of sensor rows, the arrangement position, and the display on the display unit are not limited to those shown in the drawing, and can be applied to a simulation device that only practices putters.

In the above embodiment, the horizontal detection switch is used as the main switch, but it goes without saying that it may be a normal manually operated switch. In this case, a reliable manual switch operation becomes possible.

As the operating means for activating the CPU, various means other than the impact sound detecting means can be considered as long as the CPU is activated based on an operation given by the user. For example, a proximity sensor that activates the CPU when the club head is approached may be arranged on the rubber plate 5, or a contact sensor that activates the CPU when the club head is pressed may be arranged on the rubber plate 5. You may.

Embodiments included in the present invention will be described below.
