Description of the invention: [Technical field of invention] Field of the invention Dong Yuming is concerned with a mini printer 5 + ^ n. a mini-printer with a means for absorbing the noise generated by the printing device that prints the product name or cost on the paper and the appropriate separation distance between the head and the platform, thus having a Simple construction. C PRIORITY]| BACKGROUND OF THE INVENTION Generally, a mini-printer is used to issue a receipt printed with a product name or cost, and includes a paper feeding device for loading and moving paper and a The name or cost of the product is printed on paper. Figure 1 is a perspective view of a conventional mini printer. This conventional mini printer has the function of printing credit card bills. 15 A conventional mini printer includes a paper guide 2 attached to a front end of a printer main body 1 to load paper; an upper paper guide 3, and a lower paper guide 2 Separating a specified interval to allow paper to be inserted into a gap between the lower and upper paper guides f and ^; a paper supply motor 4 for feeding into the gap between the lower and upper paper guides 2 and 3 Paper; a supply reduction gear unit $, which is used to reduce the rotation speed of the paper supply motor 4; a rotary shaft 6, which is axially connected to the 2, 7 reduction gear unit 5 and rotates without inserting the sprocket wheels on both sides 7; a carriage 9a for mounting a head 9 for performing a printing operation on paper; and a leading flange 10 provided with a long groove 10a formed in the outer periphery for receiving The head carriage 9a has a projection (not shown) and is driven by a drive horse 1273980 to slam the ground_slide %. When the rotary mini-printer receives the print command, the drive motor 8 is driven to the front guide. The power of the factory is transmitted via a gear member (not shown). 5 10 15 Flange ^4 (4) (4) (4) After the cap is missing: 9 9 moves horizontally and receives - electrical signals from - substrate B. In the above mechanism of the two mini printers, the head 9 is an impact head. When the thimble of the field and the 9 hit the paper, the stylus produces a sound. Solution = The figure shows one of the conventional mini printers and the head of the mini printer. In the mini printer known in Fig. 1, the head 9 directly strikes - the noise is generated by the platform 21 of an iron. In particular, in the case where the platform 21 is made up of smashing, the impact is severe noise, thus causing noise > can be traced, and conventionally, a gap between the platform 21 and the head 9 is set to 0.4 to 〇· 6, PCT. Conventional mini-printer advances include a head gap adjustment lever such as a gap between the adjustment platform 21 and the head 9. As shown in Fig. 3, the head gap adjusting lever 22 is inserted into the end points of a guide shaft, respectively, and the guide head is slipped (four), and has a cam structure. When the two-end gap adjusting lever 22 inserted into the both ends of the guide shaft 23 is simultaneously rotated, ?丨 The guide shaft 23 moves slightly forward or backward. The above-mentioned conventional printer system requires an operator to combine and fix the head gap adjustment 1273980 lever 22 to the guide shaft 23 such that the guide shaft 23 is moved by the head gap adjustment lever 22 to move the head 9 between the head 21 and the platform 21. The gap is set in the range of 0.4 to 0.6 mm and the gap is maintained, thus causing inconvenience in assembly thereof. The guide shaft 23 of the conventional mini printer is mounted separately from the leading flange 10 to move the head 9. Figure 4 is a longitudinal cross-sectional view showing the connection between the leading flange and the head of the conventional mini printer. Referring to Figures 3 and 4, the guide shaft 23 is axially coupled to an axial connecting tube 24 mounted on the head carriage 9a, and the projection 10 9b of the head carriage 9a is inserted into the leading flange 10 Inside the groove 10a in the outer periphery. When the guide flange 10 is rotated, the projection 9b of the head carriage 9a is horizontally moved along the groove 10a of the leading flange 10, thereby allowing the head carriage 9a to move. A disadvantage of the above-described conventional mini-printer comprising the guide shaft 23 for carrying the head 9 is that the size of the head carriage 9a and the mini-printer is increased. Further, in the case where the stylus protruding from the paper head 9 hits the paper from the paper, the paper powder falls on the leading flange 10, thereby hindering the operation of the leading flange 10. Therefore, the conventional mini printer requires a configuration that prevents the above problems. SUMMARY OF THE INVENTION [Invention] Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a mini printer comprising a sound for producing a maximum amount of shock and an adjustment head and A properly separated distance between the components, thus reducing noise, having a simple construction, and facilitating a 1273980 assembly procedure.
