  • a table tennis board 1 supported by legs 2 has an appropriately wide and rectangular surface which inclines down toward the place behind the center of said surface.
  • a backnet or backsheet 3 is spread up at the rear brim of the table tennis is board 1.
  • the low place of the center of said board 1 is cut out and provided with a shooting means 4 which comprises a shooting frame 5, an inclined guide rail 6, a ball supplier 7 having an inclined guide channel 8, an obstructing bar 10, a rotating means 11 having a pair of ball hitting plates 12 and 12.
  • Said inclined guide rail 6 is fixed to the upper portion of the shooting frame 5 so as to lead spontaneously the balls onto said guide channel 8.
  • Said ball supplier 7 is inserted in a square hollow 9 of the shooting frame 5 and the upper portion of the ball supplier 7 become said inclined guide channel 8 which inclines down toward the rear opening of a long rectangular hollow 13.
  • Said ball supplier 7 is pivoted with a supporting axis 15, which is fixed at the bottom edge of said supplier 7, inside said square hollow 9 so as to turn up and down said ball supplier 7.
  • a contact member 16 attached to the side of said ball supplier 7 adjacent to the rectangular hollow 13 engages with a pair of bosses 17 and 17 of said rotating means 11.
  • Said obstructing bar 10 is fixed on the upper surface of said shooting frame 5 between said square hollow 9 and said rectangular hollow 13 so as to obstruct dropping the ball 14 on the hollow 13.
  • Said rotating means 11 comprises a pair of side rotating plates 18 and 18, two pairs of supports 19a, 19a, 19b and 19b and a pair of said ball hitting plates 12 and 12, and is pivoted with a rotating axis 20 inside said rectangular hollow 13.
  • Each said ball hitting plate 12 are pivoted with each one of the first pair of said supports 19a, respectively, between a pair of said side rotating plates 18 and 18.
  • a pair of tensile spiral springs 21 and 21 are hung between a base edge of each said ball hitting plate 12 and each one of the second pair of said supports 19b, respectively, so as to pull said ball hitting plates 12 and 12.
  • Said bosses 17 and 17 are protruded outside one of said side rotating plates 18 as the extension of the supports 19b and 19b so as to engage with said contact member.
  • each of said bosses 17 touches to and separates from said contact member 16 once during one revolution of said rotating means '11, therefore the ball supplier 7 is turned above by touch and is turned below by separation twice during one revolution of said rotating means 11.
  • the guide channel 8 is raised above the obstructing bar 10 upper surface of the shooting frame and the rear opening of the rectangular hollow 13 so as to adjust the upper surface of the shooting frame 5 and the rear opening of the rectangular hollow 13 so as to adjust the opening of said rectangular hollow '13 and to control the repulsion of the ball hitting plates 12 by contact with said repulsion adjusting plate 2, and a stem 23 of the repuulsion adjusting plate 22 is protruded from the rear side of the shooting frame 5.
  • a position adjusting bar 24 having a stopper 25 at the front portion of said bar 24 is slidably attached along the longitudinal brim of the rectangular hollow 13 opposite to the obstructing bar and a stem 26 of said bar 24 is protruded from the rear side of the shooting frame 5
  • some table tennis balls which are charged on the table tennis board 1, collect around the shooting frame 5.
  • Said balls 14 are led one by one onto said inclined guide channel 8 of said ball supplier 7 through said inclined guide rail 6 by inclination of said rail 6.
  • the rotating means 11 rotates as shown by the arrow mark in FIGS. 4 and 6-8.
  • the repulsion adjusting plate 22 may be protruded at will on the opening of said rectangular hollow 13 by the stem 23 and the extremities of the ball hitting plates 12 and 12 are made to engage with the front portion of said adjusting plate 22. Therefore, the tensile spiral spring 21 and 21 are stretched and reserves the repulsion as shown in FIGS. 6 and 7. When the protrusion of the adjusting plate 22 on the opening of said rectangular hollow 13- is longer, the repulsion is stronger.
  • the ball hitting plate 12 is disconnected from the adjusting plate 22 as shown in FIG. 8, the ball 14 mounted on the opening of the rectangular hollow 13 is hit by said ball hitting plate 12 and flied toward the front of the board 1. The ball 14 falls on said board 1 and bounds toward a trainee. Then said ball 14 is struck back by a racket, flied toward the backnet 3, warded on said backnet 3, falls on the board 1 and rolls down the lower place of said board 1.
  • Each said boss 17 pushes up slightly the ball supplier 7 by contact with the contact member 16 while the ball hitting plate 12 separates from the repulsion adjusting plate 22. Therefore the inclined guide channel 8 is raised above the obstructing bar 10 and the ball 14 laid on said inclined guide channel crosses over said obstructing bar 10 and falls on the empty opening of said rectangular hollow 13. Thus the balls 14 are alternately supplied and shot by the shooting means 4.
  • the repulsion of the ball hitting plates 12 and 12 may be controlled by adjusting the length of protrusion of the repulsion adjusting plate 22 on the opening of the rectangular hollow 13, namely when the protrusion of the repulsion adjusting plate 22 is longer, the tensile spiral spring 21 is made to stretch longer and reserves the stronger repulsion. Accordingly, when the protrusion of the repulsion adjusting plate 22 is shorter, the repulsion of the ball hitting plate 12 is weaker. Therefore, the strength hitting the ball 4 is controlled according to the skill of the trainee.
  • Said position adjusting bar 24 is provided so as to slide on the longitudinal brim of said rectangular hollow 13 and said stopper 25 is attached to the front portion of said position adjusting bar 24 in order to adjust the position of the ball 14 to ride on the opening of the rectangular hollow 13.
  • the direction hitting the ball 14 is different according to the position of the ball 14 riding on the opening of the rectangular hollow 13, namely when the position adjusting bar 24 is pushed forward, the ball 14 is hit at the relatively high surface of the ball 14 so as to fly low said ball 14 and when the position adjusting bar 24 is pulled rearward, the ball 14 is hit at the relatively low surface of the ball 14 so as to fly highly said ball 14.
  • this invention may control not only the shooting strength but the flying height in accordance with the skill of the trainee, therefore he may alone train the table tennis in various ways. Also, the trainee need not pick up the back struck balls, therefore he may absorbedly train only hitting.
  • this invention is the table tennis training device which is very available for physical training and table tennis technique.
