Not applicable.REFERENCE TO MICROFICHE APPENDIX FIELD OF THE INVENTION
The present invention relates generally to table tennis equipment, and more particularly to a machine which is designed to serve the table tennis ball.BACKGROUND OF THE INVENTION
There are a variety of conventional Ping-Pong service machines available in the market place today. These conventional Ping-Pong service machines are composed of many complicated electronic devices and are therefore rather expensive, thereby making them beyond the means of the Ping-Pong enthusiasts in general.BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a table tennis service machine which is simple in construction and cost-effective, thereby making it affordable to the sporting public.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the table tennis service machine which is designed to serve the table tennis ball by mechanical means rather than electronic means. The machine of the present invention comprises simple mechanical devices, such as drive gear, ball feeding device, deceleration gears, ball ejecting device, etc.
The features and functions of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

As shown in FIG. 1, a table tennis service machine “A” of the present invention is in use such that it is set up at the opponent end of a Ping-Pong table 05 in conjunction with a ball tray 06 and a net 07.
As shown in FIGS. 2-10, the table tennis service machine “A” of the present invention comprises a housing 10, a drive motor 20, a deceleration gear set 30, a ball ejecting member 40, and a ball feeding member 50.
The housing 10 is provided with a guide slot 11, an assembly slot 12, and an ejection slot 13. The guide slot 11 is provided at the top end with a port 14. The ejection slot 13 is provided at the top end with an opening 15. The assembly slot 12 is located between the guide slot 11 and the ejection slot 13. The ejection slot 13 is provided therein with a guiding tube 16 which is in turn provided with an elongated through slot 17 in communication with the assembly slot 12.
The drive motor 20 is mounted in the assembly slot 12 and is provided with a drive gear 21 which is mounted on an output shaft of the motor 20.
The deceleration gear set 30 is mounted in the assembly slot 12 and is formed of a plurality of gears. In other words, the deceleration gear set 30 is formed of a first driven gear 31, and other driven gears 32 and 35. The first driven gear 31 is engaged with the drive gear 21 of the motor 20. The driven gear 32 is fastened with a push plate 33 which is provided at the top end with a protrusion 34.
