The positioning member 14 can pass through the frame 15, and one of the positioning hole 122 and the transition hole 123

When the positioning member 14 is engaged with the transition hole 123, the first passage plate is in an invertible state, and as shown in FIG. 2a, the first passage plate 12 is rotatable about the rotation shaft 121. When the first passage plate 12 is not subjected to an external force, the positioning member 14 supports the first passage plate 12 to maintain the initial position through the transition hole 123. In this position, the first passage plate 12 and the second passage plate 13 are substantially parallel, A passage for conveying paper is formed between the persons. In the case where the first passage plate 12 is subjected to the printing paper thrust, it can be rotated about the rotating shaft 121 in the direction of opening the passage, thereby forming a first space between the first passage plate 12 and the second passage plate 13 for temporarily storing the printing paper.

For example, a clamping shaft is disposed on one end side or both end sides of the first channel plate, and a card hole corresponding to the clamping shaft is disposed on the frame, and the clamping shaft can be fitted or separated from the card hole by elastic deformation. When the snap-in shaft cooperates with the card hole, the first channel plate 12 is fixed on the frame; when the card-connecting shaft is separated from the card hole, the first channel plate 12 can be turned away from the second channel plate with respect to the frame. The first passage plate or the second passage plate is provided with support members on both sides in the width direction of the paper conveying passage, such as a support plate or a supporting elastic piece, so that the first passage plate maintains a set distance between the second passage plates. Used to transport paper through. The second passage plate 13 is located at one side of the second rotating roller 112, and is disposed between the second rotating roller 112 and the second rotating roller 112 to form a paper opening D. The first passage plate 12 extends at the top of the paper opening D, and the paper The second paper-receiving space E2 below the second passage plate 13 can be accessed through the paper-receiving opening D. The second rotating roller 112 can be rotated in both directions under the driving of the paper-receiving motor 15, and conveys the printing paper to advance or retreat. Between the downstream of the paper-retaining rubber roller 11 and the paper discharge port Q of the paper-receiving mechanism, a sensor 17 is provided for detecting whether the printing paper reaches a predetermined position, thereby controlling the paper-receiving motor 15 to perform a corresponding action. A printing device having a paper-holding mechanism and working according to the present invention will be described below with reference to FIGS. 5 and 6. As shown in FIGS. 5 and 6, the printing apparatus includes a printing unit 3, a paper cutting unit 2, and a paper roll supporting unit 4. The paper roll support assembly 4 supports a paper roll R for printing; the print unit 3 is located downstream of the paper roll support assembly 4 for printing an image or text on the print paper R.

Next, the operation of the printing apparatus using the paper accommodating mechanism of the present invention will be described. When the positioning member 14 is engaged with the transition hole 123, when the first passage plate 12 is hinged with the frame 16 of the paper-receiving mechanism, the working principle of the paper-holding mechanism 1 is as shown in FIG. After the printing device receives the print command, the printing rubber roller 32 drives the printing paper to advance downstream of the printing assembly, and at the same time, the second rotating roller 112 of the paper-holding mechanism is driven by the paper-receiving motor 15 to rotate in the paper feeding direction, and the printing paper is sent. When the sensor 17 of the paper-holding mechanism 1 detects that the printing paper passes, the paper-adhesive roller 11 stops rotating, and the printing rubber roller 32 continues to drive the printing paper to advance. The printing paper pushes the first channel plate 12 upward, and the printing paper is inverted "U," and the drum is temporarily stored in the first paper space El. After the printing is finished, the cutter assembly 2 cuts the printing paper; the paper conveying motor 15 The second rotating roller 112 is driven to rotate in the paper feeding direction to continue the printing paper; the paper-filling rubber roller 11 drives the printing paper temporarily stored in the first paper-receiving space E1 to be gradually discharged from the paper discharge port Q until the paper-filling rubber roller 11 Only the end of the printing paper is clamped, and the first passage plate 12 is gradually turned to the initial position as the printing paper is reduced. When the printing paper is not taken away after waiting for the set time, the paper conveying motor 15 drives the second transfer. The 112 rotates in the ejecting direction, and the printing paper enters the second paper-receiving space E2 through the paper-receiving opening D, and falls into the inside of the paper-receiving mechanism 1 for recycling, thereby effectively preventing leakage of user information. When the positioning member 14 is engaged with the positioning hole 122, when the first channel plate 12 is fixedly connected to the frame 16 of the paper-receiving mechanism, the working principle of the paper-holding mechanism is as shown in FIG. 6. After the printing device receives the print command, the printing rubber roller 32 drives the printing paper to advance downstream of the printing assembly, and at the same time, the second rotating roller 112 of the paper-holding mechanism is driven by the paper-receiving motor 15 to rotate in the paper feeding direction, and the printing paper is sent. When the sensor 17 of the paper-holding mechanism 1 detects that the printing paper passes, the paper-adhesive roller 11 stops rotating, and the printing rubber roller 32 continues to drive the printing paper to advance. Under the pressing action of the first passage plate 12, the printing paper enters the second paper-receiving space E2 from the paper-receiving opening D, and is temporarily stored in the second paper-receiving space E2 in a "U" shape. After the printing is finished, the cutter assembly 2 cuts the printing paper; the paper conveying motor 15 drives the second rotating roller 112 to rotate in the paper feeding direction to continue the printing paper; the paper-loading rubber roller 11 is temporarily driven in the second paper-receiving space E2. The printing paper is gradually ejected from the paper exit Q until the paper towel roller 11 only grips the tail of the printing paper. When the paper is not taken away after waiting for the set time, the paper conveying motor 15 drives the second transfer 112 to rotate in the ejecting direction, and the printing paper enters the second paper-receiving space E2 through the paper opening D, and falls into the paper. The paper-receiving mechanism 1 is internally recycled and stored, thereby effectively preventing leakage of user information. 7, 8, 9, 10 and 11 show the structure of a paper accommodating mechanism according to a second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the form and the mating relationship of the positioning member and the second passage plate are different. Referring to FIG. 7 to FIG. 9 , the positioning member 14 passes through the surface of the frame 16 of the paper-receiving mechanism, and is engaged with the frame 16 through the elastic clip 143 provided on the outer circumference thereof, and the positioning member 14 and the frame 16 are matched with the frame 16 . It is cylindrical, so that the positioning member 14 is pulled, which can be indexed along its own axis. The positioning member 14 has a pivoting portion 141 and a limiting protrusion 142 on a side of the interior of the frame 16. The first passage plate 12 is inserted and pivotally engaged with the connecting portion of the positioning member 14 through the rotating shaft 121 disposed on the side thereof; the first passage plate 12 is overlapped with the second passage plate 13 through the supporting plate 124 disposed on the inner surface thereof. The height of the support plate 124 is such that a set distance is maintained between the first passage plate 12 and the second passage 13 to convey the medium. When the positioning member 14 is rotated to be in the first position (as shown in FIG. 7), the limiting protrusion 142 is overlapped with the outer surface of the first passage plate 12 to prevent the first passage plate 12 from moving away from the second position. The direction of the passage plate 13 is rotated, and at this time, the paper-receiving mechanism can hold the paper using the second paper-receiving space E2. When the positioning member 14 is rotated to be in the second position (as shown in FIG. 8), the limiting protrusion 142 is located below the inner surface of the first passage plate 12, so that the first passage plate 12 can be rotated around the rotating shaft 121. Rotating (flip) away from the second passage plate 12, at this time, the paper-holding mechanism can hold the paper using the first paper-conveying space E1. The working principle of the paper-holding mechanism is the same as that of the first embodiment, and will not be mentioned here. In the paper-receiving mechanism of the present invention, a person skilled in the art can select the positioning manner of the first channel plate as needed, so that the first channel plate can be selectively in a fixed state and a reversible state, and for the fixed state, including but not It is limited to the use of a positioning shaft or a pin or the like for plug fixing, snap fixing, solder fixing, riveting fixing, etc., and when the fixed state is released, it is in a reversible state. As can be seen from the above description, in the paper-receiving mechanism of the present invention, the first channel plate can be fixed or reversible relative to the frame of the paper-holding mechanism, so that the paper-holding mechanism has two paper-receiving positions to be selected, thereby improving The versatility of the paper-holding mechanism. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the scope of the present invention are intended to be included within the scope of the present invention.
