利用红外光传感器和较少的电子器件，设计了一种乒乓球全自动供球器．该供球器能够满足运动员连续用球的需要，一旦储球仓中的球被用尽，输运电机停转，并自动报警，以示服务人员向球仓内补充球源；当球仓内装入适量的球后，供球器便自动恢复向运动员自动供球的功能，既省去了一个传统方法中所需的专门向运动员递球的人员，又提高了训练效率；另附有练球数量自动记录、显示功能，亦可为教练员决定下步训练方案提供依据．所以，该全自动供球器有较强的应用前景．

An automatic table tennis ball server is designed by using infra-red sensor and a few electric devices. This type of server will meet the ball-players＇ continuous needs of balls. Once the container are out of bails, the motor that provides balls stops, at the same time the alarm is automatically turned on to alert the staff to add more balls into the balls container; when the ball container has been filled with appropriate amount of balls, the device will restore its automatic function of serving balls to the players. By using this device, it is unnecessary to arrange a person to serve the balls; the efficiency of training is improved as well. In addition, the device automatically records and counts the ball serving. This can provide a basis for the coaches to decide on the next step in the training program. Therefore, the automatic ball provider has a hopeful future in its application.
