Title: Mounting structure of cassette with protruded supporter to main body

Description:
BACKGROUND 
     The image forming apparatus is an apparatus for generating, printing, receiving, or transmitting image data. Examples of the image forming apparatus include a printer, a scanner, a copy machine, a fax machine, and a multifunction printer integrating these functions. The image forming apparatus includes a main body for generating image data and printing the generated image data on a printable media, and at least one cassette configured to supply the printable media to the main body. 
     In general, a size of the image forming apparatus depends on a maximum size of the available printable media. For example, if the image forming apparatus is capable of printing on A4 printable media, the size of the image forming apparatus is larger than the A4 printable media. In addition, if the image forming apparatus is capable of printing on both A3 printable media and A4 printable media, the size of the image forming apparatus is larger than A3 printable media.

     The main body  110  is formed with a cassette groove  120  having a shape corresponding to the cassette  200 . The cassette groove  120  may be formed at a lower part of the main body  110 , but is not limited thereto. The cassette  200  can be mounted in the cassette groove  120  to supply the printable media  24  loaded in the cassette  200  to the main body  110 . The cassette groove  120  includes a part of the first side surface  112  and a part of the second side surface  114  of the main body  110 . In further detail, the cassette groove  120  includes a corner at which the first side surface  112  and the second side surface  114  are joined, and has a square pillar shape (the shape of the cassette groove  120  is not limited to the square pillar shape) formed by extending the part of the first side surface  112  to the other side in the second direction by a predetermined length and by extending the part of the second side surface  114  to the rear side in the first direction by a predetermined length. Thus, the third side surface  116  and the fourth side surface  118  of the main body  110  can directly support the main body  110  with respect to the ground, but the parts of the first side surface  112  and the second side surface  114  included in the cassette groove  120  cannot support the main body  110  directly. A guide rail (not shown) may be formed on the inner surface of the third side surface  116  facing the cassette groove  120 . The guide rail may be formed along the first direction to set a moving direction and a mounting position of the cassette  200  in the cassette groove  120 . 
     A lever  122  that is moveable along the first direction, for example, as a pivot lever  122  pivotable along the first direction (i.e., pivotable about the second direction) is equipped on a lower surface of the main body  110  corresponding to the cassette groove  120 . The pivot lever  122  is movable at least between a supporting position at which the pivot lever  122  can support the main body  110  and a release position at which the pivot lever  122  allows for entry of the cassette  200 . The pivot lever  122  is rotated by the cassette  200  when the cassette  200  is mounted in the cassette groove  120  so as not to hinder the cassette  200  from being mounted in the cassette groove  120 . In one example, the pivot lever  122  is pivotally mounted to the main body  110  via a pivot pin  124 , but is not limited thereto. That is, any mounting method for allowing the pivot lever  122  to pivot to the first direction by the cassette  200  may be applied. 
     When the cassette  200  is mounted in the cassette groove  120 , the pivot lever  122  rotates toward the rear side in the first direction by the cassette  200 , and when the cassette  200  is separated from the cassette groove  120 , the pivot lever  122  rotates toward the front side in the first direction by the cassette  200 . When the cassette  200  is completely separated from the cassette groove  120 , the pivot lever  122  is positioned vertically by its own weight. 
     The pivot lever  122  is located on a path where the cassette  200  passes when the cassette  200  is mounted in the cassette groove  120 . In one example, the pivot lever  122  may be located at an entrance of the main body  110  through which the cassette  200  enters the main body  110 . In another example, the pivot lever  122  may be located at a corner portion where the first side surface  112  and the second side surface  114  are joined, but a position of the pivot lever  122  is not limited thereto. When the pivot lever  122  is positioned at the corner where the first side surface  112  and the second side surface  114  are joined, the main body  110  can be stably supported against the ground by the pivot lever  122  together with the lower end portions of the third and fourth side surfaces  116  and  118 . 
     The lower surface of the main body  110  corresponding to the cassette groove  120  may be formed with a lever groove  126  to accommodate the pivot lever  122 , but formation of the lever groove  126  is not limited thereto. When the cassette  200  is mounted in the cassette groove  120 , the pivot lever  122  may rotate toward the rear side in the first direction and be accommodated in the lever groove  126 . In this example, an upper surface of the cassette  200  is adapted to support the main body  110  through the pivot lever  122 . In further detail, the pivot lever  122  is interposed between the lower surface of the main body  110  corresponding to the cassette groove  120  and the upper surface of the cassette  200  in a state that the cassette  200  is mounted in the cassette groove  120 . In addition, the pivot lever  122  is in contact with the lower surface of the main body  110  and the upper surface of the cassette  200 . In this state, the lower surface of the cassette  200  may be located on the same plane as the other lower surface of the main body  110 , which is not included in the cassette groove  120 . Accordingly, while the cassette  200  is mounted in the cassette groove  120 , the lower surface of the cassette  200  may support the image forming apparatus  100  against the ground along with the other lower surface of the main body  110 . 
     The shape of the pivot lever  122  may be a rectangular bar shape, but is not limited thereto. In order to facilitate the rotation of the pivot lever  122 , a lower end of the pivot lever  122  may be positioned higher than the other lower surface of the main body  110 , which is not included in the cassette groove  120  by a predetermined height (G) (see  FIG. 5 ). Accordingly, when the cassette  200  is mounted in the cassette groove  120  while the image forming apparatus  100  is positioned on the ground, the lower end of the pivot lever  122  may rotate without interference with an inner bottom surface of the cassette  200 . 
       FIG. 3  illustrates an internal structure of an image forming apparatus according to an example of the present disclosure. The image forming apparatus  100  according to an example of the present disclosure includes therein a plurality of developing units  30 C,  30 M,  30 Y, and  30 K to develop an electrostatic latent image into a visible image through a developer (e.g., a toner), an exposure unit  40  to form the electrostatic latent image on a photosensitive body  31  of each charged developing unit  30 C,  30 M,  30 Y or  30 K, a transfer device  50  and  60  to receive the printable media  24  from the cassette  200  and transfer the visible image formed on the photosensitive body  31  to the printable media  24 , and a fixing unit  70  to fix the developer transferred to the printable media  24 . In addition, a discharge port  132  for discharging the printable media  24  on which the image forming is completed is provided at a side of the printable media output box  130 . 
     Each of the developing units  30 C,  30 M,  30 Y,  30 K includes the photosensitive body  31  having a charged surface on which the latent electrostatic image is formed by the exposure unit  40 , a developing roller  32  for supplying the developer to the photosensitive body  31 , and a charging roller  33  for charging the surface of the photosensitive body  31 . 
     In one example, the developing units  30 C,  30 M,  30 Y, and  30 K is comprised of four developing units  30 C,  30 M,  30 Y, and  30 K which store different colors of developers, for example, cyan C, magenta M, yellow Y and black K, respectively, to develop the images of cyan C, magenta M, yellow Y, and black K. The four developing units  30 C,  30 M,  30 Y and  30 K are arranged in parallel with one another beneath the transfer device  50  and  60 . 
     The exposure unit  40  irradiates light including image information to the photosensitive media  31  provided at each developing unit  30 C,  30 M,  30 Y, or  30 K to form the electrostatic latent image on the surface of each photosensitive body  31 . 
     The transfer devices  50  and  60  includes a first transfer unit  50  to which the visible image formed by the developer is transferred from the developing units  30 C,  30 M,  30 Y, and  30 K, and a second transfer unit  60  to transfer the visible image on the first transfer unit  50  to the printable media  24 . The second transfer unit  60  includes a transfer roller  65 . 
     The first transfer unit  50  includes a transfer belt  51  that is an intermediate transfer body to which the developer developed on the photosensitive bodies  31  of the developing units  30 C,  30 M,  30 Y, and  30 K in the form of a visible image is transferred in an overlapping manner, a driving roller  52  and a driven roller  53 , each disposed at both sides of the transfer belt  51  to rotate the transfer belt  51 , and a plurality of rollers  54  disposed opposite to the photosensitive bodies  31  of the developing units  30 C,  30 M,  30 Y, and  30 K with the transfer belt  51  interposed therebetween to transfer the visible image formed on the photosensitive bodies  31  to the transfer belt  51 . The rollers  54 , the drive roller  52 , and the driven roller  53  are rotatably mounted on a transfer belt frame (not shown). 
     The fixing unit  70  includes a heating roller  71  for generating heat, and a pressure roller  72  having a peripheral surface that is made of an elastically deformable material to press the printable media  24  against a peripheral surface of the heating roller  71 . 
     In addition, the main body  110  is provided therein with a feed roller  84  for guiding the printable media  24  supplied from the cassette  200  upwardly, a conveying roller  12  disposed above the fixing unit  70  and guiding the printable media  24  passing through the fixing unit  70  toward the discharge port  132 , and a discharge unit  90  arranged adjacent to the discharge port  132  and discharging the printable media  24  through the discharge port  132 . The discharge unit  90  includes a pair of discharge rollers  91  disposed inside the discharge port  132 . 
     The feed roller  84  is configured to receive a front end of the printable media  24  from the cassette  200  and to feed the printable media  24  to an image forming unit (e.g., the transfer devices  50  and  60 ). 
       FIG. 4  is a perspective view illustrating a cassette according to one example. As shown in  FIG. 4 , the cassette  200  according to one example includes a lower frame  210  and first, second, and third frames  220 ,  230 , and  240  protruded upwardly from an edge of the lower frame  210 . A shape of the cassette  220  corresponds to a shape of the cassette groove  120  as a whole. The first, second, and third frames  220 ,  230 , and  240  are protruded upwardly from the lower frame  210  to form a space for loading the printable media  24  between the first and second frames  220  and  230 . 
     The lower frame  210  has a rectangular plate shape corresponding to the shape of the cassette groove  120 , and a knock-up plate  260  and an elastic member  262  are disposed on the lower frame  210  to support a bottom surface of the printable media  24 . In detail, the printable media  24  are loaded on the knock-up plate  260 , and the elastic member  262  elastically supports the knock-up plate  260 . 
     In addition, a pair of printable media guiders  270  is movably mounted on the lower frame  210 . The pair of printable media guiders  270  guides both sides of the printable media  24  with respect to the second direction so that the printable media  24  can move along the second direction while maintaining a constant posture. At least one of the pair of printable media guiders  270  is movably mounted along the first direction on the lower frame  210  to set a distance between the pair of printable media guiders  270  to correspond to the size of printable media  24  loaded in the cassette  200 . 
     The first frame  220  protrudes upwardly from the front side of the lower frame  210  in the first direction. A handle  222  is formed in the first frame  220  to facilitate a user to grasp the handle  222  to mount the cassette  200  in the cassette groove  120  or to separate the cassette  220  from the cassette groove  120 . 
     The second frame  230  protrudes upwardly from the rear side of the lower frame  210  in the first direction. The first and second frames  220  and  230  may be formed by a predetermined length along the second direction. 
     The third frame  240  protrudes upwardly from the other side of the lower frame  210  in the second direction. The third frame  240  may be formed along the first direction between the first and second frames  220  and  230 . A guider (not shown) corresponding to the guide rail may be mounted on an outer surface of the third frame  240  corresponding to the inner surface of the third side surface  116  of the main body  110 . The guide rail and the guider allow the cassette  200  to be mounted in the cassette groove  120 . In another example, the guider may be formed on the inner surface of the third side surface  116  and the guide rail may be formed on the outer surface of the third frame  240 . In addition, means for guiding the cassette  200  to be mounted in the cassette groove  120  is not limited to the guide rail and the guider. 
     A pick-up unit  250  may be mounted at the third frame  240 . The pick-up unit  250  includes a pick-up roller  252 , a friction pad  254 , a shaft  256 , and a gear  258 . 
     One end of the shaft  256  is equipped with the gear  258 , which is connected with a power source (not shown) and is powered. The shaft  256  is also equipped with the pick-up roller  252 . The gear  258 , the shaft  256  and the pick-up roller  252  can rotate together. In further detail, when the gear  258  receives power from the power source, the shaft  256  and the pick-up roller  252  fixedly mounted on the shaft  256  rotate. 
     The pick-up roller  252  is configured to contact the printable media  24  loaded on the knock-up plate  260 . An external circumference of the pick-up roller  252  is made of a material with high friction coefficient so that the printable media  24  can be picked up one by one by applying friction force to the printable media  24  while the pick-up roller  252  rotates. 
     The friction pad  254  is mounted opposite to the pick-up roller  252 . The friction pad  254  causes the pick-up roller  252  to move the printable media  24  one by one by generating friction force greater than the friction force between the printable media  24 . 
     There is no frame protruding upwardly at a side of the lower frame  210  facing the third frame  240 . That is, the one side of the cassette  200  in the second direction is opened. In addition, the lower frame  210  includes a supporter  300  extending to the one side in the second direction. An upper surface of the supporter  300  may be coplanar with an upper surface of the lower frame  210  to support the bottom of the printable media  24 . One end  330  of the supporter  300  in the second direction is bent upwardly. In one example, a rail  320  is formed along the second direction on the supporter  300 , and a slider  310  may be mounted on the rail  320  to be movable along the second direction. The slider  310  can be moved on the rail  320  to meet the size of the printable media  24  loaded in the cassette  200  and push the printable media  24  toward the pick-up unit  250  to facilitate a pick-up operation of the pick-up unit  250 . In addition, the slider  310  prevents the printable media  24  from leaving the cassette  200  due to vibrations or the like occurring during the image forming operation. 
     According to another example of the present disclosure, as shown in  FIG. 9 , the supporter  300  itself may be movable along the second direction relatively to the cassette  200 . In further detail, a groove may be formed in the lower frame  210  along the second direction, and the supporter  300  may be mounted in the groove through guide means. In this example, the one end  330  of the supporter  300  plays a role of pushing the printable media loaded in the cassette  200  toward the pick-up unit  250 . 
     Since the one side of the cassette  200  in the second direction is opened and the supporter  300  extending in the second direction is formed at the lower frame  210 , the printable media  24  larger than a size of the lower frame  210  can be loaded in the cassette  200 . For example, if the lower frame  210  is provided which can load an A4 printable media such that a long side of the A4 printable media is aligned with the first direction, the cassette  200  can load an A3 printable media through the supporter  300  extending to the one side in the second direction such that a long side of the A3 printable media is aligned with the second direction (see  FIG. 3 ). Typically, a cross-section of the main body  110  in a vertical direction is slightly larger than a cross-section of the cassette groove  120  in the vertical direction, and the cross-section of the cassette groove  120  in the vertical direction corresponds to a cross-section of the cassette  200  in the vertical direction. Accordingly, an image can be formed on the A3 printable media by using the image forming apparatus capable of forming an image on the A4 printable media, thereby significantly reducing a size of the image forming apparatus supporting the A3 printable media. 
     In addition, when the cassette  200  including the supporter  300  is mounted in the cassette groove  120 , the pivot lever  122  rotatable in the first direction is positioned on the path through which the cassette  200  passes (e.g., an entrance through which the cassette  200  enters the cassette groove  120 ). The pivot lever  122  is positioned on a path through which the first frame  220  and the second frame  230  pass, and may be rotated in the first direction by the first frame  220  or the second frame  230 . Accordingly, the pivot lever  122  supports the lower part of the main body  110  in which the cassette groove  120  is formed, and does not hinder the cassette  200  from being mounted in the cassette groove  120 . 
       FIG. 5  to  FIG. 7  illustrate processes of mounting a cassette to an image forming apparatus according to one example of the present disclosure; and  FIG. 8  illustrates a process of separating a cassette from an image forming apparatus according to one example of the present disclosure. 
     As shown in  FIG. 5 , the printable media is loaded into the cassette  200  when the cassette  200  is separated from the main body  110 . For example, the A4 printable media may be placed in the cassette  200  such that the long side of the A4 printable media is aligned with the first direction, and the A3 printable media may be placed in the cassette  200  such that the long side of the A3 printable media is aligned with the second direction. After that, the slider  310  is moved on the rail  320  or the supporter  300  itself is moved to push the printable media  24  towards the pick-up unit  250  according to the size of the printable media loaded in the cassette  200 . At this time, the pivot lever  122  is positioned vertically by its own weight. That is, the pivot lever  122  is positioned at the release position to allow the cassette  200  to enter. 
     As shown in  FIG. 6 , when the cassette  200  begins to enter the cassette groove  120 , the second frame  230  rotates the pivot lever  122  to the rear side in the first direction. Accordingly, the pivot lever  122  is seated in the lever groove  126 . 
     As shown in  FIG. 7 , when the cassette  200  is fully seated in the cassette groove  120 , the first frame  220  of the cassette  200  rotates the pivot lever  122  to the rear side in the first direction and seats the pivot lever  122  in the lever groove  126 . In other words, the pivot lever  122  is positioned in a supporting position to support the main body  110 . The first frame  220  together with the pivot lever  122  supports the main body  110  against the ground. 
     When the cassette  200  begins to be separated from the cassette groove  120 , the first frame  220  is released from the cassette groove  120 . In this case, the pivot lever  122  is positioned vertically by its own weight between the first and second frames  220  and  230 . That is, the pivot lever  122  may be positioned at the release position. 
     As shown in  FIG. 8 , when the cassette  200  is further pulled out of the cassette groove  120 , the second frame  230  rotates the pivot lever  122  to the front side in the first direction. Accordingly, the pivot lever  122  does not hinder the cassette  200  from being separated from the cassette groove  120 . When the cassette  200  is completely out of the cassette groove  120 , as shown in  FIG. 5 , the pivot lever  122  is positioned vertically by its own weight. That is, the pivot lever  122  returns to the release position.
