Description of the invention: [Examination of households with 4 members and 4 members] FIELD OF THE INVENTION The present invention is related to-5 sets of paper feeding devices for moving paper in a mini printer, more particularly related to-in-printing Mini printer for credit card billing ^ Paper feeding device for easy paper loading, paper removal when paper is stuck in the device, and reduced size to meet the miniaturization of the mini printer. L 关 ^ 前 ^ ^: Dongshu] 3 Background of the invention 10—In general, 'mini printers are used to issue receipts printed with the product name or cost, and mainly include a paper for delivery and moving paper Paper feeding device and printing device for printing the name or cost of the product on paper. FIG. 1 is a perspective view of a conventional mini printer. Fig. 2 is an exploded perspective view of a paper feeding device, which is one of the conventional mini printers. 15 The paper feeding device of the mini printer includes a lower paper guide 2 attached to a front end of a printer main body 1 to load paper; a upper paper guide 3, Separation of paper guide 2-Specify a space for paper to be inserted into a gap between the lower and upper paper guides 2 and 3; a paper supply motor 4 for generating driving force to supply the lower and upper paper guides Paper in the gap between 2 and 3; a supply 20 to the reduction gear member 5 for reducing the rotation speed of the paper supply motor 4; a rotating shaft 6 which is axially connected to the supply reduction gear unit 5 and rotates, and a chain The wheel 7 is inserted into both sides of the rotation shaft 6 respectively; and the artificial round handle 8 is mounted on one end of the rotation shaft 6. In the conventional paper feeding device shown in FIG. 3, a user inserts a finger of paper 200536717 Pingxing 9 into one of the lower paper guide 2 and the upper paper guide 3 fixed to the printer main body 1. Within the gap, the sprocket wheel 7 is rotated to load the paper 9 onto the paper feeding device. The paper 9 is loaded by a paper feeding device using an automatic loading method or a manual loading method. 5 In the automatic loading method, when a user presses a supply key mounted on a terminal, the paper supply motor 4 rotates by outputting a signal from the supply key to generate power, and the power is supplied through a reduction gear member 5 is transferred to the rotation axis 6. Then, the sprocket wheel 7 connected to the rotation shaft 6 is rotated so that the projection 7a of the wheel 7 engages the transfer hole 9a formed through the paper 9. Therefore, the paper 9 is loaded to a specified position by the rotation of the sprocket wheel 7 10. In the manual loading method, an artificial round handle 8 fixed to the rotation shaft 6 is rotated by a user's hand, so that the sprocket wheel 7 connected to the rotation shaft 6 is rotated, and the protrusion 7a of the wheel 7 is engaged with the paper 9 The transfer hole 9a is formed so that a specified amount of paper 9 is loaded. Subsequently, in order to set an accurate position of the paper 9, the automatic loading method described above is performed. Since the above-mentioned conventional holding device of the mini printer has a narrow gap between the lower paper guide 2 and the upper paper guide 3, when the user holds the paper 9 and inserts the paper 9 into the lower paper guide 2 and the upper paper It is difficult to insert the paper 9 in the gap between the guides 3 evenly between the lower paper guide and the upper paper guide 3. Therefore, it is difficult to always load the paper 9 and cause the paper 9 to jam. In the gap. Also, in the case where the paper 9 is stuck in the gap between the lower paper guide 2 and the upper paper guide 3, due to the conventional knowledge of a mini printer, the feed saki is placed between the lower paper guide 2 and the upper paper guide 3. Remove the jammed paper 9 with a narrow gap 'difficult_gap'. If the jam is torn off when the jam is removed from the _ multi, as shown in 200536717 Figure 4, the fragment 9b of the paper 9 is trapped by the gap between the lower paper guide 2 and the upper paper guide 3 . For this reason, the mini printer stops operating until the trapped sheet 9b is removed from the gap, and in order to remove the sheet 9b from the gap between the lower paper guide 2 and the upper paper guide 3, the mini printer must be disassembled or repaired Printer. 5 As mentioned above, because it is difficult to stably insert the paper into the conventional paper feeding device of the mini printer, and in the case where the paper is not stably inserted into the device in the initial paper feeding step, the paper is not loaded to a paper station. A disadvantage of the conventional paper feeding device is that the jammed paper must be taken out of the gap, which causes inconvenience for the user to load the paper and requires 10 skilled techniques when loading and feeding the paper. SUMMARY OF THE INVENTION Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a paper feeding device that can easily load paper and completely remove the paper in which the card 15 is, and a device having Mini printer for the paper feeding device. Another object of the present invention is to provide a paper feeding device having a small size to meet miniaturization of a mini printer, and a fan printer having the paper feeding device. According to one aspect of the present invention, the above-mentioned and other objects can be achieved by providing a paper feeding device, the paper feeding device including: a lower paper guide attached to a front end point of a printer body; An upper paper guide assembly, which is placed on an upper surface of the lower paper guide and hinged on the printer main body to center and rotate on a hinge to adjust an opening position and a lower paper guide together with the lower paper guide. A gap between the closed positions; a paper feed motor for generating a driving force 200536717 to feed paper inserted in a gap between the lower paper guide and the upper paper guide assembly, and a reduction gear member, It is used to reduce the speed of the paper feed motor. One side of the rotary shaft is axially connected to the supply reduction gear member. The sprocket wheel is inserted into the two ends of the rotary shaft and is provided at a specified interval and inserted through the paper. A protrusion in the transfer hole; a locking member for locking and releasing the paper guide assembly to adjust the paper guide assembly between the open position and the M position; and miscellaneous items installed on the upper call bar Demystifying the chain scarf as a shackle member The paper guide always depends on the paper guide to the open position. 10 15.
