Field of the Invention The present invention relates to a printer, and more particularly to a printer having a handle on a paper carrier to prevent the pickup roller from directly contacting the paper carrier. Prior Art Fig. 1 is a conventional paper carrier of a printer, and Fig. 2 is an enlarged view of a portion of the drawing. On the paper carrier 1 of the conventional printer, if there is still a subsequent printing operation after the paper is finished, the pickup roller 20 will continue to rotate and entangle the mi!, which causes a large friction and is likely to cause When there is no paper on the pickup roller 2〇1〇, the pickup roller 20 falls into the recessed portion to perform idling, and the non-coupling directly contacts the paper-carrying table 1〇 to avoid the above problem.曰 疋 疋 'When the pickup roller 20 rotates to take the paper, especially when the thickness of the two sheets on the paper carrier is small, it is easy to be influenced by the influence of the paper take-up wheel 2° on the paper printed with high quality. Use invention content, such as photo printing paper. In view of the above, the problem to be solved by the present invention is that the paper table is in contact, and at the same time, the paper is not produced when the paper passes through the paper loading table. A preferred embodiment of the printer of the present invention comprises an i agricultural paper wheel and at least one Idler. For the paper table: Use the second: Take the bottom of the pickup roller. When the paper loading table is on the paper table, the position wheel 'and the idler wheel is accompanied by the paper take-up rotation=the wheel is in contact with the idle power yang. The Μ Μ avoids the paper take-up wheel directly. 1248876 V. Invention description (2) Contact with the paper carrier Preferably, each of the broad axes is perpendicular to each other. In the case of the soil K, the shaft of the idler and the preferred embodiment of the paper take-up wheel are included in the soft-wired net f including a soft piece, combined with the idler, and held at an appropriate distance, soft and The idler wheel, and the paper take-up rim, is protected by the above-mentioned _ # ~ shell material may include rubber. Between the tables, the pick-up wheel needs to be worn. 2. It includes a friction member, which is set on the idler and the paper-loading idler. The friction between the wheel and the friction member drives the above-mentioned better: :: With a shape. And the armrest is pivotally connected to the binding member, and is disposed on the lower shaft portion of the paper carrier. The idler has a shaft, a second, and the coupling member is a rotating wheel, and has a connection to the paper carrier. station. The hunter is coupled to the shaft hole by the shaft portion, so that the circumscribing wheel has a snap-fit hole in the above-mentioned preferred embodiment, and the hook has a -hook'-loading table. , σ σ is in the 5 hole of the card, so that the idler is pivoted to the carrier. In order to make the present invention t μ go me _ 这 and other purposes, features, and superior fields are obvious, the following is a light sag The anvil is described in more detail below. 1 and her example, and with the accompanying drawings, the third embodiment is a printer of the present invention.

Description of invention (3) 1 0 0 contact. As shown in the figure, the rotating shaft of the idler 3 〇〇 is perpendicular to the rotating shaft of the pickup roller 2 〇 0. When there is no paper on the paper loading table and the printer continues to print, the idler 300 will be accompanied. The paper wheel rotates 200, and its direction of rotation is as indicated by the arrow in Fig. 3. Figure 4 is an exploded view of the idler and other mating components of the present invention. A recessed portion 1 2 0 ' is provided on the paper loading table 100 for accommodating the idler gear 3 q 〇, and a friction member 4 设有 is provided between the idler wheel 300 and the recessed portion 120, and the idler 3 〇 There is a soft piece 500 on the raft. In the present embodiment, the idler gear 3 is coupled to the underside of the deck 10 by a rotating wheel (joining member) 600, and is pivotally connected to the recess 120. Figures 5 and 6 show the state in which the idler 3〇〇 is coupled to the runner 6 。. The runner 60 has a shaft portion 6 2 〇, the idler pulley 3 has a shaft hole 3 2 〇, and the shaft portion 62 0 is coupled to the shaft hole 32〇 through the through hole 122 of the recess 120, thereby making the idler 300 is pivoted in the recess 1 120. Figure 7 is a cross-sectional view of the idler 3 〇 〇 pivotally connected to the paper table 1 〇 。. The friction member 40 0_ is annular, and is disposed between the idler pulley 3〇〇 and the recessed portion 12〇. The idler pulley 3〇〇 has a flange 3 40 that abuts against the friction member 400. When there is paper on the paper carrier 1 , the idler 3 does not rotate due to the friction of the friction member 4 ,, and when the last paper is taken, the pickup roller 2 〇〇 directly contacts the paper The idler 3 〇 (), due to the torque of the ', the wheel of the '60', the idler 3 〇〇 can overcome the friction of the friction member 4 二 two η back: the enlarged view of the part of the figure. Wherein the idler 30 〇 is maintained at an appropriate distance D from the load and the surface, and the edge of the soft member 5 做成 is formed in an arc shape to reduce the indentation when the paper passes, and the distance D is smoother and D is smoother. The smaller the indentation. Soft parts $ (four)
