## Abstract

Provided is a ball supply integrated type auto tee-up machine with a simple structure, and more particularly, to an advanced concept technology for easily improving a structure of an auto tee-up machine while performing complexly a function of supplying a golf ball to a golf tee and a function of teeing-up the golf ball on the golf tee by using a single motor. The present invention provides a technique to implement a function of allowing a second ball chute to supply a golf ball to a golf tee and a function of teeing-up the golf ball placed on the golf tee with one-stop automation after delivering the golf ball inserted to a first ball chute to the second ball chute while the golf tee and the first ball chute ascend/descend and the second ball chute descends/ascends in an opposite direction at the same time by using a single tee-up motor.
