Adjusting device of a coin operated amusement assembly

Abstract

An adjusting device of a coin operated amusement assembly includes a drive device mounted onto a back of a horizontal board of the coin operated amusement assembly. A transmission device is connected to the drive device. Two adjusting plates are respectively and wiggly mounted to two opposite side of the horizontal board and inserted into a corresponding one of two return passages of the coin operated amusement assembly. Two driven devices are respectively connected to the transmission device and a corresponding one of the two adjusting plates for lifting the two adjusting plates and adjusting the odds of the coin operated amusement assembly.

What is claimed is: 
     
         1 . An adjusting device of a coin operated amusement assembly, comprising:
 a drive device adapted to be mounted onto a back of a horizontal board of the coin operated amusement assembly;   a transmission device connected to the drive device;   two adjusting plates adapted to be respectively and wiggly mounted to two opposite side of the horizontal board and inserted into a corresponding one of two return passages of the coin operated amusement assembly; and   two driven devices respectively connected to the transmission device and a corresponding one of the two adjusting plates for lifting the two adjusting plates and adjusting the odds of the coin operated amusement assembly.   
     
     
         2 . The adjusting device as claimed in  claim 1 , wherein the drive device is a step motor and has a drive shaft extending therefrom, the transmission device including a rotary plate co-axially secured to a distal end of the drive shaft, a drive linkage including a first end pivotally connected to a periphery of the rotary and a second end having a pivot extending therefrom, wherein the drive linkage is reciprocally moved when the drive device is operated and the rotary plate is rotated. 
     
     
         3 . The adjusting device as claimed in  claim 2 , wherein the driven device comprises two driven linkages each including a first end having a longitudinal groove defined therein for allowing the pivot extending through the first end of each of the two driven linkages, each driven linkage including a second end pivotally connected to a first end of a connecting linkage that has a second end pivotally connected to a back of a corresponding one of the two adjusting plates for lifting the two adjusting plates when the driven device is operated. 
     
     
         4 . The adjusting device as claimed in  claim 3 , wherein each driven linkage has a middle portion adapted to be pivotally connected to the back of the horizontal board by a connect rack that is adapted to be secured on the back of the horizontal board. 
     
     
         5 . The adjusting device as claimed in  claim 2  further comprising an index plate co-axially secured on a back of the rotary plate. 
     
     
         6 . The adjusting device as claimed in  claim 5 , wherein the index plate includes a first indentation and a second indentation respectively defined in a periphery thereof, the first indentation and the second indentation defining a circumferential angle that is the rotary range of the index plate. 
     
     
         7 . The adjusting device as claimed in  claim 6 , wherein the index plate includes a brake device that is an electromagnetic mechanism including a rod selectively extending into a corresponding one of the first indentation and the second indentation for holding the index plate in place.
