BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This present invention relates to a stamping toy, and in particular, to a stamping toy which can produce sound and lighting effect to attract the attention of children. 
     2. Description of the Prior Art 
     The construction of conventional stamping toy available in the market is of two types, which are shown in FIG. 7 and FIG. 11 of the drawings. As shown in FIG. 7, there is shown a first type of the conventional stamping toy having a light transmitting ornamental design 91, an ornamental seat 92, a spring 93, a moveable seat 94 having a stamping design 97, a main body 95 and a bottom cap 96 which is used to cover the main body 95. These parts are combined together to form the stamping toy 9 which is shown in FIG. 8. As shown in FIG. 9, a light emitting body 922 is provided on the ornamental seat 92 containing two batteries 925. One contacting leg 924 of the light emitting body 922 is kept in contact with the negative terminal of the batteries 925. A small hole 921 is provided at one lateral side of the ornamental seat 92. A round head push button 923 is contained within the small hole 921 and the top portion of the push button 923 is in contact with the top edge of the moveable sat 94. The ornamental seat 92 is connected to the moveable seat 94 by a spring 93. Due to the extension force of the spring 93, the moveable seat 94 is urged downward. FIG. 10 shows the light emission of the stamping toy 9. The bottom cap 96 is removed and the stamping design 97 is placed one a sheet of paper. When the stamping design 97 is pressed, the moveable seat 94 moves upward and the top edge urges the round head push button 923 to retract into the small hole 921. At the same time, the push button 923 urges the contacting leg 924 of the light emitting body 922 to contact with the positive terminal of the batteries 925 and the stamping toy 9 is thus lighted. 
     The second type of conventional stamping toy is shown in FIG. 11. The stamping toy comprises a light transmitting ornamental design 30, an ornamental seat 31, a buzzer 32, a circuit board 33, a stopping plate 34, a pressing spring 35, a conductive press key 36, a shafted disc 37, a stamping design 38, a main body 39, an outer cap 301, and a light emitting body 302 having two batteries 303. These parts are mounted together to form a stamping toy 300 which is shown in FIG. 12. 
     FIG. 13 illustrates the procedures of sound and lighting production. The outer cap 301 is removed and the stamping design 38 is placed on a sheet of paper. When the stamping toy 300 is pressed, the shafted disc 37 moves upward and the press key 36 at the top triggers the conductive end of the circuit board 33, such that the light emitting body 302 and the buzzer 303 produce a sound and a lighting effect. 
     Other than the above methods of providing a sound and a lighting effect, there are simpler methods with convenient control for a stamping toy to produce sound and lighting effect in accordance with the present invention. 
     SUMMARY OF THE INVENTION 
     The present invention comprises an ornamental seat, a main body mounted a the bottom of the ornamental seat, a bottom cap mounted at the bottom of the main body, a spring within the ornamental seat, a circuit board mounted at the bottom of the spring, a light emitting body, a plurality of batteries and a conductive spring being provided on the top of the circuit board, an isolation annular rim mounted at the bottom of the circuit board, a voice emitter (buzzer) mounted at the bottom of the isolation annular rim, a stamping seat mounted at the bottom of the voice emitter, and a rubber stamping design provided a the bottom of the stamping seat. 
     In accordance with one aspect of the present invention, the ornamental seat is fixed to the main body and the stamping seat, a voice emitter, an isolation annular rim and he circuit board are mounted within the main body. When the ornamental seat is pressed, the ornamental seat and the body are lowered, and the stamping seat and the voice emitter, the isolation annular rim and the circuit board move upward at the same time such that one end of the conductive spring on the circuit board is biased and lowered to touch the terminal of the batteries as a result of the protruded rim on the ornamental seat. Thus, the voice emitter and the light emitting body produce a sound and lighting effect. 
     When the pressure of the stamping toy is released, the restoration force of the spring causes the ornamental seat and the main body to rise upward and the stamping seat, voice emitter, an isolation annular rim and the circuit board move downward to their respective position. In addition, the conductive spring restores to its original position without touching the batteries. Thus, neither sound nor lighting effect is produced.

The combination of these parts to form a stamping toy 10 is shown in FIG. 2 of the present invention. 
     Referring to FIG. 3 of the present invention, there is shown a sectional view of the stamping toy 10. The lower section of the inner wall of the main body 1 is provided with a stepped, protruded top stopping rim 12 and a bottom stopping rim 13, wherein the bottom stopping rim 13 is functioned to block the stamping seat 12 so as to prevent its dislocation from the main body 1. The stamping seat 2 has a recess 21 having downward facing opening for the adaptation of a rubber stamping design 3. Further, the top stopping rim 12 is functioned to block the dislocation of the voice emitter 22, and the voice emitter 22 is located at the top of the stamping seat 2 and in contact with the stamping seat 2. On the top of the voice emitter 22, the isolation annular rim 23, the circuit board 5 are mounted. The isolation annular rim 23 is functioned to prevent short circuit of the circuit board 5. 
     In accordance with the present invention, the main body 1 and the bottom cap 4 are mounted together tightly. When the stamping design 3 is not in use, the bottom cap 4 covers the stamping design 3 to avoid contamination and to prevent ink evaporation from the stamping design 3. 
     The top end of the inner wall of the main body 1 is provided with a circular rib 11 engageable with the circular groove 71 at the bottom edge of the external wall of the ornamental seat 7 to form a unit. A cylindrical body 74 is protruded out from the top end of the ornamental seat 7, wherein a small hole 72 is provided at the center thereof for the mounting of a light emitting body 51 (for instance, Light Emitting Diode). A protruded rim 73 is extended out from the center bottom face of the ornamental seat 7, and it is used to urge the conductive spring 55. In accordance with the present invention, the conductive spring 55 is a L-shaped spring having one end being mounted onto the circuit board 5 and the other free end being a downward bent contacting disc 551. The contacting disc 551 is located at the top end of the battery 54 but does not contact with the battery 54. 
     Two battery slots 53 are provided on the circuit board 5 and contain two batteries 54. An IC member 52 is provided on the circuit board 5, which is used to control the duration time for the light emitting body 51 and the voice emitter 22 to provide a lighting a sound effect. 
     Referring to FIG. 4, when the stamping toy 10 is used. The bottom cap 1 is removed. At this instant, the contacting disc 551 of the conductive spring 55 has not in contact wit the terminal of the battery. Thus, the IC member 52 does not function, and neither the light emitting body 51 nor the voice emitter 22 is functioned. 
     Referring to FIG. 5, when the stamping toy 10 is pressed downward. The ornamental seat 7 and the main body 1 move downward altogether, and the stamping seat 2, the voice emitter 22, the isolation annular rim 23, the circuit board 5 rise upward at the same time such that the spring 6 is at a state of compression. At this moment, the protruded rim 73 of the ornamental seat 7 urges the conductive spring 55 and causes the contacting disc 551 to contact with the terminal of the batteries 54. In addition, the IC member 52 is thus activated. This will cause the light emitting body 51 to flash and the voice emitter 22 to produce a sound (music) until a controlled time has attained. 
     In accordance with the present invention, when the pressure is released. The spring 6 causes the ornamental seat 7 and the main body to rise upward, and the stamping seat 2, the voice emiteer 22, the isolation annular rim 23 and the circuit board 5 move downward so as to urge the ornamental seat 7 and the main body 1 to move upward at the same time and return to their original positions. At this moment, the conductive spring 55 restores to its original shape and does not contact with the terminal of the batteries 54. At this point, the current to the IC member 52 is terminated and the sound and lighting effect is thus stopped. 
     Referring to FIG. 6 of the present invention, the stamping toy 10 can be provided with ornamental designs such as transparent or translucent animation figures or cartoon figures. In accordance wit the present invention, the stamping toy 10 can provide either with a voice emitter 22 or a light emitting body 51.
