The tee support 3 is composed of an upper slider 4 made of a synthetic resin having lubricity, a metal weight 5 and a lower slider 6 made of a synthetic resin having lubricity. The upper slider 4 and the lower slider 6 are arranged at a predetermined interval (via the weight 5), and slide on the surface of the guide wall 2. In this embodiment, the case where the upper slider 4 and the lower slider 6 slide on the surface of the guide wall 2 has been described. However, a plurality of guide rollers are provided on the tee support 3 side, and the surface of the guide wall 2 is rolled. It may have a moving structure. The tee 7 is fixed on the tee support 3, and the golf ball 8 is placed on the tee 7. The presence or absence of the golf ball 8 on the tee 7 is detected by, for example, an optical sensor 9. A part of the wire 10 is connected to the upper slider 4,
The wire 10 extends toward the drum 12 (see FIG. 2) via the guide roller 11. Reference numeral 13 in FIG. 1 denotes a mat laid on the concrete floor 1. As shown in FIG. 2, the other end of the wire 10 is connected to the peripheral surface of the drum 12, and the rotation of the drum 12 causes the wire 10 to be wound or unwound, so that the tee 7 is turned into an arrow A shown in FIG. 1. Move up and down in the direction. The drum 12 is a motor 14 capable of rotating forward and reverse.
The motor 14 is appropriately rotated forward, backward, and stopped by a control signal from the control unit 15, and a signal indicating that there is a ball and no ball is input from the sensor 9 to the control unit 15. As shown in FIG.
The two arc-shaped grooves 16a, which extend in the circumferential direction, are provided at a position apart from a portion where the wire 10 is wound up on the peripheral surface of the two.
16b are formed. In FIG. 3, for simplification of the drawing, it is shown as one groove 16. Groove 16a is tee 7.
The groove 16b is for a standby position for setting the standby position (home position) of the tee 7, and the groove 16b is for the standby position for setting the tee-up position (ball hitting position). The tee-up position detecting means 17a is arranged on the rotation locus of the tee-up position groove 16a, and the standby position detecting means 17b (see FIG. 3) is arranged on the rotation locus of the standby position groove 16b. As shown in FIG. 3, the tied-up position detecting means 17a includes a tied-up position detecting first micro switch 18-1a and a tied-up position detecting second micro switch 18-2a.

It has. Although not shown, the detection signals of these four microswitches 18 are input to the control unit 15 and used for driving control of the motor 14. Reference numeral 19 in FIG. 3 denotes a changeover switch. When the sensor 9 detects that the golf ball 8 is on the tee 7, the switch is switched to the terminal a as shown by a solid line, and the sensor 9 hits the golf ball 8 on the tee 7. When it is detected that the vehicle is hit, the terminal is switched to the terminal b as shown by a dotted line. The changeover switch 19 is provided in the control unit 15. Next, the operation of the automatic tee-up device at the time of raising the tee will be described mainly with reference to FIGS. When the sensor 9 detects that the golf ball 8 is on the tee 7 as described above, the changeover switch 19 is switched to the terminal a as shown by the solid line, and the tee-up position detecting means 17a is in an operable state and the standby position is detected. The means 17b is in a state of operation suspension. At this time, the tee 7 is in the lower position as shown in FIG. 1, the drum 12 is rotated clockwise as shown in FIG. 4 by the motor 14, and the wire 10 is wound around the drum 12, and the tee 7 is raised accordingly. .
