Conventional paper feeding devices are usually equipped with a 'roller' to feed paper or documents into a transaction machine or to be dispensed in a transaction machine, for example, when the printer's rollers or paper feed rollers perform a printing paper feed operation' Will use the friction between the roller and the paper to bring the paper into the printer; but as far as those familiar with the art know, the roller will adhere to the foreign matter caused by dust or aerosol::01) The force is gradually reduced, and the paper, the feeding or the paper feeding effect is not sure or even disappeared, and this situation is not what we expected. In order to scrape the above problems, the art has also revealed the concept of applying the brush 9312〇188 3 "the means of perspiration on the roller; for example, the typical roller device of Taiwan" provides a Ϊ Touch (four) 'received in the roller action, by the brush to achieve the representative of the cleaning roller, this inflammatory 去 丨 θ — the relevant design of the paper feeding device in the transaction machine, in some applications : It also reflects that the paper feeding device is placed on a paper, so that its construction is different from that of the old method if the re-designed user's 'will change its usage type and operation 5 200940357. Compared with the concept of applying the brush cleaning roll $ in the art, the present invention provides a design for the roller device 1 'can be used in the non-side riding of the roller, self-riding, or on the roller' The mechanism for automatically opening the roller causes the roller to be attached by dust or suspended particles: the situation is considered to be the lowest subject, and is not displayed or specifically disclosed in the above-mentioned reference materials. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a kind of roller protection device, which is equipped with an i_, j frame, which is placed on a base frame, and can be reciprocated and actuated. The cover system is movable in response to the reciprocating motion of the actuating arm to move between a first leg f and a second position to open or close the roller; and a bouncing between the arm 3 and the cover The cover is in the first position of the open ^ wheel. However, when the roller is not in use, the establishment of the cover automatically closes the roller, so that the suspended particles contaminate the roller is recited. According to the roller protection I of the present invention, the elastic component has a second second end embedded separately The shoulder portion and the cover of the actuating arm are formed so that the cover is hung in the first position of the open roller. 2 According to the roller-sliding device of the present invention, the cover is mixed with a convex portion or a pin, and when the movable arm is double-reacted, it interferes with the base frame, and forcing the cover to be closed to the second position will have novelty, _ ' And other purposes and effects of the style of the detailed description, and tend to understand; as shown: L Α fine" mode] Eyes refer to Figures 1, 2, the roller protection of the present invention | set includes a pedestal, 200940357 The boom is shown in FIG. 1; the base frame 1G has a pivoting portion 11 for pivoting one for the implementation of the disk. The tree 20 has a pivoting portion 21, and the moving portion 1 is connected to the connecting portion U. And the actuator arm 20 is formed into a reciprocable or oscillating type. ❹

In the implementation of the riding, the fitting portion 22 has a convex portion or a hinged pivotal shell. The cover 4 is configured to move the cover 4 响应 between the first position and the second position in response to the movement of the actuator to open or close the roller 30. The second cover also shows the cover 4 The tether has a projection or pin 41 that interferes with a wall 12 that is grasped on the base 10 when the actuator 20 is moved or relocated toward the base 1 (5), forcing the cover Then, the second position = the closing roller 30 (this portion will be described later). ..., the elastic member 50 is disposed between the operating arm 20 and the cover 4; specifically, the elastic member 50 The sleeve is sleeved on the convex portion or the shaft of the actuator fitting portion 22, and has a first end 51 embedded in a shoulder portion 24 formed on the fitting portion 22; and a second end 52. It is fixed on the cover 4〇, and the shell position is always in the first position of the open roller 30. " ~ Please refer to Figures 3 and 4 to describe the reciprocating motion of the actuator 20. It is shown that when the roller 30 performs the paper feeding or the paper feeding operation, the actuator arm is in a position after moving forward (moving to the right position in the figure); at this time, the cover 4 is restricted by the elastic member 50, And in the first position of the open scroll wheel 3', the scroll wheel 30 is moved or re-actuated to the left side of the figure after the completion of the paper feeding or paper feeding operation, and the convex portion of the cover 40 Or the pin 41 will interfere with the wall 12 of the pedestal 10 as shown in Fig. 4. ', no, please refer to Fig. 5, as the boom 20 continues to swing to the left in the figure, the ❹ Ο state In terms of design, the space 200940357u is in contact with the convex portion of the cover, and the elastic element 50 is pressed to accumulate energy; straight: the second position is turned as shown in Fig. 6. The roller 30 can be understood. On the right side of the example, the elastic element 50 in the figure will release the previously accumulated energy, chasing the direction of the head, and the third position of the wheel, for example, the second side of the wheel is open and rolled. The roller 30 can perform the paper feeding or the belt to automatically open the roller 30; when the roller is like a household / ± #双盍40 series protection shop The storage of the Ϊ Ϊ self-correction, the establishment of a dye roller 30, was reduced to a minimum of 3 rounds, so that the suspension of the dirt system "roller protection device in her knowledge of the skills, 1 · compared to the biography The wire is difficult to read # and the structural type is obviously different from the conventional structure. The concept of the fine brush cleaning the roller means that the device is provided with a protection mechanism, which can be used when the roller 3 is not in use. , the automatic wheel, or the wheel 3, or when the roller 3G is in the general state, the above-mentioned details of the roller are only used as a possible embodiment of the present invention, and are not intended to limit the scope of the present invention, that is, All the changes and modifications made by the special fiber package according to this is a cover for the invention. 200940357 [Simplified description of the drawings] Fig. 1 is a schematic view showing an embodiment of the roller protection device of the present invention.
