(a) Field of the Invention
The present invention relates to a card vending machine, and more particularly, to a card vending machine which includes a gear unit, a transmission roller and output rollers to automatically send cards one by one.
(b) Description of the Prior Art
Card vending machines are used to sell telephone cards, star cards, ball player cards, game cards, and the like. The cards have different thicknesses, such as 0.85 mm, 0.7 mm, 0.4 mm or 0.25 mm. A conventional card vending machine comprises a complicated gear transmission mechanism and a transmission belt to send the cards out. After a period of time, the transmission belt will become elastic fatigue.
Taiwan Utility Model Publication No. 237972 titled “automatic card delivery mechanism” and Taiwan Utility Model Publication No. 233837 titled “automatic card output device” use a transmission belt to deliver cards. However, after a period of time, the transmission belt will become elastic fatigue. The cards cannot be outputted smoothly. Sometimes, the cards may be jammed. The conventional card vending machine also comprises a complicated gear transmission mechanism, so the entire assembly is complicated and the cost is high.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to provide a card vending machine which comprises 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. The card vending machine of the present invention can output the cards exactly and smoothly. The entire configuration of the present invention is compact and the parts can be assembled easily to lower the cost.
Preferably, the machine base further comprises a movable arm and a first sensor located under the card storage recess. The card storage recess is formed by two side boards and a wall board. The wall board is pivotally connected to the two side boards. When it is necessary to maintain the machine or to supply the cards, the wall board can be opened with ease to simplify the operation. The wall board won't be damaged or lose because of regular maintenance.
Preferably, the machine base further comprises a second sensor at a middle section of the middle partition. When the card is outputted at the beginning of the output route to pass the second sensor, the second sensor will send a signal to stop the running of the motor and the motor will be in a standby state. When the motor receives a signal to output the card, the motor will drive to output the card. After outputting the card, the motor will be in a standby state again.
Preferably, 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 terminal of the outputting route and the card is pushed out a certain distance by the output rollers, the card will cover the third sensor to stop the running of the motor to complete the output of the card.
Preferably, the machine base further comprises a stop plate corresponding in position to the terminal of the outputting route of the card. The stop plate is adapted to hold the card to be outputted. A height difference is formed between the holding position of the card and the card outlet, so that the card is slightly curved to stay at the outlet for the user to pull it out and won't fall on the ground.
Preferably, the machine base further comprises a height limit plate at a side wall of the card storage recess. The height limit plate is adapted to adjust a gap between the height limit plate and the middle partition for different cards to be outputted. The height limit plate can be slightly adjusted as desired for the best gap to output the cards.
