Description
- 1. Field of the Invention
- The present invention relates to a paper feeding device with a pickup roller that feeds a sheet of paper in a printer or a copying machine.
- 2. Description of the Background Art
- In a printer or a copying machine, a pickup roller is used to feed a sheet of paper. In a commonly used pickup roller, the surface thereof is formed of an elastic and anti-slip material such as rubber. The pickup roller is rotated to feed a sheet of paper. The surface of the pickup roller formed of rubber and the like gradually wears by the repeated operation of paper feeding. Therefore, the pickup roller needs to be replaced regularly.
- The pickup roller is rotary driven by a rotational axis. If the rotational axis is provided so as to penetrate the pickup roller, the rotational axis itself needs to be detached when the pickup roller is to be replaced. An end of the rotational axis is provided with means for transmitting driving force of a gear or a pulley to drive the rotational axis. Accordingly, it is not easy to detach the rotational axis that retains the pickup roller.
- Thus, a structure that allows the pickup roller to be replaced without detaching the rotational axis is proposed. In the structure shown in
FIG. 7 and described in Japanese Patent Laying-Open No. 10-236673, a pair ofcollars 72 is provided that is penetrated by arotational axis 71. The surface ofcollars 72 facing apickup roller body 74 is provided with a rectangularaxial member 73 and the corresponding part ofpickup roller body 74 is provided with a rectangularconcave portion 75. Whenpickup roller body 74 is to be replaced, one of the pair ofcollars 72 is shifted axially and the pickup roller body is also shifted in the same direction. Thus, rectangularaxial member 73 is disengaged fromconcave portion 75 so that fixation ofpickup roller body 74 is released. Thus,pickup roller body 74 can be replaced without detachingrotational axis 71. - In the structure shown in
FIG. 8 and described in Japanese Patent Laying-Open No. 04-075934,rotational axis 81 is provided with a pair ofrectangular holes 85 and a pair ofround holes 86.Pickup roller 82 is provided with a pair ofengaging pieces 83 and a pair ofpositioning pins 84 at respective corresponding positions. - When
pickup roller 82 is to be mounted, positioningpin 84 ofpickup roller 82 is inserted intoround hole 86 to positionpickup roller 82. By the insertion,engaging piece 83 engages withrotational axis 81 so thatpickup roller 82 is fixed torotational axis 81. For a removing operation,pickup roller 82 can be removed by pullingpickup roller 82 to pull out positioningpin 84 while releasing engagement of pair ofengaging pieces 83. - In the mounting structure of the pickup roller described in Japanese Patent Laying-Open No. 10-236673, there is a problem of increase in the number of parts since the pickup roller is formed of three parts, i.e.
pickup roller body 74 and the pair ofcollars 72 provided at opposite sides thereof. Further, there is also a problem of increase in the number of manufacturing processes, since the pair ofcollars 72 needs to be mounted torotational axis 71 and thenpickup roller 74 needs to be mounted to the mounted pair ofcollars 72 when manufacturing a printer and the like. - In the mounting structure of the pickup roller described in Japanese Patent Laying-Open No. 04-075934, there is a problem of difficulty of operation and reduced working efficiency since both of
positioning pins 84 must penetraterespective round holes 86 ofrotational axis 81 simultaneously. - An object of the present invention is to provide a paper feeding device in which detachment is easy when a pickup roller is to be replaced and that does not increase the number of parts and manufacturing processes.
- A paper feeding device according to the present invention includes a rotational axis with a groove shaped cross section having a web extending in the longitudinal direction and a flange provided at opposite sides thereof, and a pickup roller having a concave groove to receive the rotational axis. An end of the pickup roller is provided with a pair of engaging pieces that engages with a flange end portion of the rotational axis respectively, and the other end of the pickup roller is provided with a hook that is inserted into an insertion hole provided on the web of the rotational axis.
- Preferably, in the paper feeding device, the hook extends outwardly from the body of the pickup roller and forms a stepped shape having an abutting surface that abuts against the inner surface of the web.
- Preferably, in the paper feeding device, a notch for positioning is provided at a site in the flange end portion where the engaging piece engages.
- Further, preferably, in the paper feeding device, the engaging piece of the pickup roller is formed of resin and an end of the engaging piece is made to engage with the flange end portion by elasticity of resin.
- In the paper feeding device of the present invention, detachment is easy when the pickup roller is to be replaced and there is no increase in the number of parts and manufacturing processes.
- The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

Hook 15 extends outwardly from apickup roller body 11 and has a stepped shape having anabutting surface 15 a that abuts against the inner surface ofweb 41 w. Anotch 45 for positioning is provided at a site in an end portion offlange 41 f whereengaging piece 21 engages.Engaging piece 21 ofpickup roller 1 is formed of resin so that an end ofengaging piece 21 is made to engage withnotch 45 of the end portion offlange 41 f by elasticity of resin. -
Pickup roller 1 is formed of abody 11 of pickup roller of synthetic resin, and anon-slip material 31 of rubber provided on the perimeter thereof. Non-slipmaterial 31 occupies about two-thirds of the area of the perimeter surface ofpickup roller body 11. As shown inFIG. 6 ,non-slip material 31 is pressed against the surface of asheet 53 of paper and sends outsheet 53 in the paper feeding direction whenpickup roller 1 is rotated. Thus, a material that has a certain degree of elasticity as well as frictional force with respect to a sheet of paper is selected. -
Pickup roller body 11 serves to retainnon-slip material 31 and is fixed torotational axis 41.Pickup roller body 11 is provided withconcave groove 25 extending to the center ofpickup roller body 11.Concave groove 25 also extends in the longitudinal direction (the axial direction) ofpickup roller body 11 and is exposed at the opposite sides thereof as shown inFIGS. 1 and 2 . - One end of
pickup roller body 11 is provided with pair ofengaging pieces 21. As shown inFIG. 1 ,engaging pieces 21 are formed as a cantilever that are pendent downwardly from opposite sides of abase portion 22 protruding horizontally from an end surface ofpickup roller body 11. As shown inFIG. 1 , the end portion ofengaging piece 21 has a crochet hook shape and the end portion engages with the end portion offlange 41 f ofrotational axis 41 from the outside.Pickup roller body 11 and engagingpiece 21 are formed of synthetic resin so that the end portion of engagingpiece 21 can be made to engage withflange 41 f ofrotational axis 41 by elasticity of resin. - The other end of
pickup roller body 11 is provided withhook 15, as shown inFIG. 2 .Hook 15 is formed to have a stepped shape protruding outwardly frompickup roller body 11. Withpickup roller body 11 mounted torotational axis 41, the upper surface of an end portion ofhook 15 forms an abuttingsurface 15 a that abuts against the inner surface ofweb 41 w ofrotational axis 41. -
Rotational axis 41 shown inFIG. 3 is made of metal and includesweb 41 w andflange 41 f provided at opposite sides thereof and has a groove shaped cross section. Apaper feeding cam 47 formed of synthetic resin is provided at opposite ends ofrotational axis 41. Near the center ofrotational axis 41 is provided aninsertion hole 43 into whichhook 15 ofpickup roller body 11 is inserted.Insertion hole 43 is formed as a rectangular hole provided onweb 41 w. Further, at a position in the end offlange 41 f away frominsertion hole 43 by a predetermined distance is provided anotch 45 where engagingpiece 21 ofpickup roller 1 engages to determine an engaging position of engagingpiece 21. - Then, a procedure to mount
pickup roller 1 torotational axis 41 will be described. First, as shown inFIG. 4 , hook 15 ofpickup roller 1 is inserted intoinsertion hole 43 ofrotational axis 41. Next, mounting ofpickup roller 1 is completed by pressing down the opposite side ofpickup roller 1 to engage engagingpiece 21 withnotch 45 of the end offlange 41 f from the outside. Thus, in thepickup roller 1 of the present embodiment,pickup roller 1 can be mounted very easily. - In the mounting structure of the pickup roller described in Japanese Patent Laying-Open No. 04-075934, it is necessary to insert a pair of positioning pins into the rotational axis simultaneously, rendering positioning very difficult. However, in
pickup roller 1 of the present embodiment,hook 15 is latched intorotational axis 41 and then engagingpiece 21 of the opposite side is engaged so that the positioning is completed by just insertinghook 15 intoinsertion hole 43. Thus,pickup roller 1 can be mounted torotational axis 41 very easily. This effect is evident in the process wherepickup roller 1 is replaced as well as in the process wherepickup roller 1 is mounted torotational axis 41 in manufacturing a printer and the like. - Further,
rotational axis 41 is provided withnotch 45 where engagingpiece 21 engages so thatpickup roller 1 can be positioned more securely. More specifically, as shown inFIG. 4 , inpickup roller 1 of the present embodiment,hook 15 is inserted intoinsertion hole 43 from an oblique direction. Accordingly,insertion hole 43 needs to have some play. The end portion of engagingpiece 21 ofpickup roller 1 and notch 45 are formed to exactly fit together so that backlash ofpickup roller 1 after installing can be eliminated. It is to be noted thatnotch 45 may be omitted and engagingpiece 21 may directly engage with the end offlange 41 f ofrotational axis 41 if backlash ofpickup roller 1 after installing is not considered as a serious problem. - When
pickup roller 1 is to be removed, first the side of engagingpiece 21 is pulled upwardly. At this stage, the engagement can be easily released since engagingpiece 21 engages through elasticity of resin. Then, hook 15 is pulled out frominsertion hole 43 to complete the removal. Thus,pickup roller 1 can be removed very easily, too. - Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
