  The present invention provides a ball collecting device for practicing table tennis, particularly a ball collecting device in which round and belt-like stretchable elongated objects are stretched on the collecting surface, and a collecting portion for discharging the collected balls. The present invention relates to an opening / closing auxiliary tool for smoothly opening and closing an upper space at a boundary portion between ball discharging portions.

  As a method for collecting a large number of balls scattered on the floor surface during table tennis practice, a scooping method using a net for catching insects or the like is currently widely used. Furthermore, methods such as Patent Documents 1 to 5 have been proposed. This is not scooping, but, for example, the elongated object 6 is stretched at an interval surrounded by the frame 2 of the scooping type ball collecting tool at an interval narrower than the diameter of the ball, and the surface on which the elongated object 6 is stretched is stretched. This is a method of collecting the ball by covering it over the ball.

  Among the methods of collecting balls by pressing, the methods of Patent Documents 4 and 5 divide the opening surrounded by the frame 2 into a ball collecting portion 7 and a ball discharging portion 8, and an elongated shape only toward the ball collecting portion 7. The object 6 is stretched and collected here. Therefore, when the balls collected here are used or transferred to another container, it is necessary to take out the balls from the holding unit 3 that collects and holds the balls. Each method is proposed in the patent literature, but the present invention particularly relates to a method for making it easier to take out the ball in Patent Literatures 4 and 5.
