Card vending machine

Abstract

A card vending machine includes a machine base, a motor, a gear unit, a transmission roller and a pair of output rollers. The machine base includes a card storage trough and a middle partition. The output rollers include upper and lower rollers. The motor drives the gear unit to turn the transmission roller and the output rollers, so that the cards in a card storage recess are outputted one by one.

What is claimed is: 
     
         1 . A card vending machine comprising a machine base, a motor, a gear unit, a transmission roller and a pair of output rollers, and characterized by:
 the machine base comprising a card storage trough and a middle partition;   the motor disposed in the machine base and connected with a main gear of the gear unit, the motor cooperating with a control board to control driving and stopping of the motor;   the gear unit comprising the main gear, a first driven gear and a second driven gear at two sides of the main gear, the main gear respectively meshing with the first driven gear and the second driven gear, the main gear synchronously bringing the first driven gear and the second driven gear to turn;   the transmission roller disposed under the middle partition of the machine base and in contact with a lowermost card  6  in the card storage recess, the first driven gear of the gear unit controlling turning of the transmission roller to push the lowermost card to move forward;   the pair of output rollers being respectively disposed above the middle partition and under the middle partition to clamp the card to be moved toward an output end of the machine base, the second driven gear of the gear unit controlling turning of the lower output roller, the upper output roller being free to turn;   thereby, the motor driving the gear unit to bring the transmission roller and the output rollers to turn synchronously, so that cards in the card storage recess being pushed out one by one.   
     
     
         2 . The card vending machine as claimed in  claim 1 , wherein the middle partition is connected with two side boards and a wall board to form the machine base, the card storage recess being disposed at an upper section of the machine base, the motor, the gear unit, the transmission roller and one of the output rollers being received in a lower section of the machine base, the output end of the machine base being coupled with a card output panel, the two side boards being respectively connected with an outer cover. 
     
     
         3 . The card vending machine as claimed in  claim 1 , wherein the main gear is composed of two gear wheels in different diameters to mesh with the first driven gear and the second driven gear, respectively. 
     
     
         4 . The card vending machine as claimed in  claim 1 , wherein the machine base further comprises a second sensor at a middle section of the middle partition, when the card passes the second sensor, the second sensor sends a signal to stop the running of the motor. 
     
     
         5 . The card vending machine as claimed in  claim 1 , wherein the machine base further comprises a third sensor corresponding in position to the terminal of the outputting route of the card, when the card passes the second sensor terminal, the motor stops running. 
     
     
         6 . The card vending machine as claimed in  claim 1 , wherein the machine base further comprises a stop plate corresponding in position to the terminal of the outputting route of the card, the stop plate holding the card to be outputted, a height difference being formed between the holding position of the card and a card outlet. 
     
     
         7 . The card vending machine as claimed in  claim 1 , wherein the machine base further comprises a height limit plate at a side wall of the card storage recess, the height limit plate being adapted to adjust a gap between the height limit plate and the middle partition for the card to be outputted, the height limit plate being connected to a fixing plate through an adjustment bolt, by turning the adjustment bolt, the height limit plate being slightly adjusted to ascend or descend so as to control the gap between the height limit plate and the middle partition. 
     
     
         8 . The card vending machine as claimed in  claim 1 , wherein the machine base further comprises a movable stop plate therein, the movable stop plate automatically stopping the card from retracting when the card passes the movable stop plate. 
     
     
         9 . The card vending machine as claimed in  claim 1 , wherein the card storage recess is formed by two side boards and a wall board, the two side boards having engaging notches and slots at upper and lower ends of an edge thereof, the wall board comprising two lock bolts and a transverse rod corresponding in position to the engaging notches and the slots, the transverse rod being pivotally connected between the slots, the two lock bolts being connected to the two side boards so that the wall board is pivotally connected to the two side boards.
