Referring to FIGS. 2C, 6A and 6B, after loading of a stack of cards 2 in the accommodation chamber 110 of the dispenser body 11, the card sensor 112 is induced by the cards 2 to output a signal to a control circuit of an automatic vending machine (not shown) so that the control circuit of the automatic vending machine can control the card dispenser 1 to dispense the cards 2. When starting a card dispensing operation, the motor 1141 is driven to rotate the transmission gear set 1142 and the wheels 1143, thereby causing the push blocks 1144 of the wheels 1143 to touch the cards 2 and to further push the cards 2 toward the actuating wheels 122. When the cards 2 touched the actuating wheels 122, the cards 2 are forced by the actuating wheels 122 into a stepped status, for enabling the push blocks 1144 of the wheels 1143 to push the lowest card 2 into the delivery path 116 toward the output port 119 of the dispenser body 11. When one card 2 is pushed out of the output port 119 of the dispenser body 11, the first sensor 1231 and the first lens 1181 detect the quantity of the card 2 been dispensed; the second sensor 1232 and the second lens 1182 detect completion of the dispensing work. After each card dispensing operation, the second sensor 1232 outputs a signal indicative of the completion of the dispensing work. Therefore, the card dispenser 1 accurately sends out the cards 2 through the output port 119 without causing any loss.
Further, the aforesaid adjustment device 121 can be an adjustment screw or control valve that matches with the roller 117 to control the gap of the delivery path 116 subject to the thickness of the cards 2 so that the cards 2 can be individually and accurately delivered out of the output port 119. Further, the cards 2 can be any of a variety of valuable notes, sports player cards, game cards, telephone cards, valuable or invaluable cards, or the like.
