PURPOSE: A ball supply device in ball dispenser is provided to consume balls by first-in-first-out principle without depositing the balls, thereby greatly decreasing failure rate. CONSTITUTION: A ball supply device in ball dispenser comprises a ball dispenser bed(20), a solder ball supply box(7), a roller(5), an arm screw(10), a screw shaft(9), a guide plate(23), a bottom support rod(11), a tension spring(25) and a ball upward feeder(33). Absorbing holes(18) are penetrated on the top surface of the ball dispenser bed(20). The solder ball supply box(7) opposes the bed(20) and the bottom face of the box is downwardly inclined. The roller(5) is mounted on the rear top end of the box to oppose a recessed rod(3). The arm screw(10) is connected to the box(20) and attached the bottom support rod(11). The screw shaft(9) is screwed with the arm screw.
