Description

  The present invention relates to an image forming apparatus such as a copying machine or a printer, and more particularly to improvement of a handle that is gripped when the image forming apparatus is transported or moved.

  In an image forming apparatus using an electrophotographic method, handling of a medium-sized or large-sized apparatus having a large weight is difficult when transported or moved. Conventionally, gripping dents have been provided on the side of the apparatus, but only the finger portion of the operator is caught, and sufficient force cannot be applied. Further, when the grip handle is protruded from the side surface of the apparatus, the carrying workability is improved, but the installation space of the apparatus is increased.

  Therefore, Patent Documents 1 and 2 disclose an image forming apparatus provided with a plurality of rod-shaped grips (handles) that can be taken in and out of the apparatus main body. According to the configurations of Patent Documents 1 and 2, the transport workability can be improved without increasing the installation space of the image forming apparatus. Further, the gripping portion of Patent Document 1 is formed in a hollow shape for weight reduction, and an anti-slip portion for preventing the hand from slipping through is formed at the end portion.

  However, in the gripping part of Patent Document 1, since the anti-slip part is formed only at the end part, there is a problem that the hand slips when the middle part of the gripping part is gripped. Further, since the anti-slip portion is formed by bending a metal plate, there is a problem that the number of bending steps increases. Further, with the demand for weight reduction of the image forming apparatus, further weight reduction of the grip portion has been demanded.

  Furthermore, depending on the installation location of the apparatus, the distance between the side surface of the apparatus and the wall or other equipment may be narrow, and the grip portion may not be pulled out to a predetermined length. However, in the configurations of Patent Documents 1 and 2, the holding position of the gripping portion is not stepwise, and it is necessary to transport the gripping portion without extending it all the way to the fixing position. Or fingers may be sandwiched between the apparatus main body and the grip portion. Further, if the length of the gripping portion is set short in advance, for example, when the operator's hand is large, only a part of the hand is caught on the gripping portion, which is dangerous.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an image forming apparatus in which an anti-slip function is provided with a simple configuration to a rod-shaped gripping member provided so as to be able to be inserted into and removed from the apparatus main body.

In the upper part of the apparatus main body 1, a document conveying device 8 capable of continuously and automatically conveying a plurality of placed documents is mounted. On the other hand, a manual paper feed tray 4d is provided on the right side of FIG.

  The fixing device 3 uses a heat roller type having two rollers, a heating roller 10 and a pressure roller 11. The heating roller 10 includes, for example, a heater connected to a power source in a cylindrical cored bar made of a metal having excellent thermal conductivity, and an elastic layer is formed on the outer periphery of the cored bar. On the other hand, the pressure roller 11 has an elastic layer formed on the outer periphery of the metal core, and a heater may be incorporated in the metal core as an auxiliary. In addition, the surfaces of the heating roller 10 and the pressure roller 11 are provided with a film made of, for example, a fluororesin to improve the releasability.

  These rollers are pressed to form a nip (fixing nip portion). Then, when the paper P on which the toner image is transferred by the image forming unit 2 described later passes through the fixing nip portion, the toner and the paper P are pressurized and heated, and the toner image is fixed on the paper P. The heating roller 10 and the pressure roller 11 in the fixing device 3 are rotationally driven at a predetermined process speed by a driving device (not shown). One of the two rollers may follow the other. Further, instead of the heat roller type fixing device 3, a belt type fixing device using a fixing belt may be adopted.

  The image forming apparatus 100 includes, for example, a large-capacity paper feed cassette 4a that stores A4 size paper P and paper feed cassettes 4b and 4c that store paper P of different sizes such as B5 size and A3 size. A total of four paper feed units, ie, cassettes 4a to 4c and a manual paper feed tray 4d are provided. In addition, a pickup roller 12 is provided in each of the paper feeding units 4a to 4d. The pickup roller 12 is rotationally driven counterclockwise in FIG. 1 by a driving device (not shown). The uppermost sheet P in contact with the pickup roller 12 is sent out toward the sheet transport path 7 one by one.

  Next, each part constituting the image forming unit 2 will be described. The image forming unit 2 includes a photosensitive drum 13 as an image carrier, a charging device 14, an exposure device 15, a developing device 16, a cleaning device 17, a transfer roller 18, and the like.

Driven.

  The charging device 14 is provided on the top of the photosensitive drum 13 and uniformly charges the surface of the photosensitive drum 13 to a predetermined potential. The exposure device 15 is provided above the photosensitive drum 13 and the developing device 16, and scans and exposes the surface of the photosensitive drum 13 charged by the charging device 14, thereby reading the document image data read by the image reading unit 6. In addition, an electrostatic latent image based on image information such as images and characters input from a computer connected to the image forming apparatus 100 is formed on the photosensitive drum 13.

  The developing device 16 is provided on the side of the photosensitive drum 13 and plays a role of supplying toner to the photosensitive drum 13 on which the electrostatic latent image is formed and developing the electrostatic latent image as a toner image. The cleaning device 17 is provided on the left side of the photosensitive drum 13 when viewed from the front, and removes and collects residual toner on the surface of the photosensitive drum 13. For example, a cleaning roller or an elastic body is formed on the blade. Consists of a cleaning blade. FIG. 1 shows an example using a cleaning roller.

  The transfer roller 18 is provided directly below the photosensitive drum 13, and is formed, for example, by winding a conductive material around the outer periphery of an aluminum shaft. The transfer roller 18 forms a nip with the photosensitive drum 13. When the paper P passes through the nip, a transfer bias having a polarity opposite to that of the toner is applied to the transfer roller 18, and the toner image on the photosensitive drum 13 is transferred to the paper P. The transfer roller 18 is rotationally driven counterclockwise at a predetermined process speed by a driving device (not shown).

  Here, an image forming operation in the image forming unit 2 will be described. First, the photosensitive drum 13 is charged to a predetermined polarity and potential by the charging device 14. Next, laser light controlled based on image data to be formed is irradiated from the exposure device 15 toward the photosensitive drum 41, and an electrostatic latent image based on the image data is formed on the surface of the photosensitive drum 13. . Next, the toner flies from the developing device 16 to the photosensitive drum 13 side, and the electrostatic latent image on the drum is developed into a toner image.

  Next, the toner image is transferred onto the paper P at the nip portion between the transfer roller 18 and the photosensitive drum 13. Thereafter, the toner image on the paper P is pressed and heated by the heating roller 10 and the pressure roller 11 and fixed by the fixing device 3 described above. The paper P discharged from the fixing device 3 is discharged out of the device by the conveying means. After the toner image is transferred, the residual toner on the surface of the photosensitive drum 13 is removed by the cleaning device 17 to prepare for the next image formation.

  The operation unit 5 is provided above the image forming apparatus 100. In the present embodiment, the operation unit 5 includes a liquid crystal display unit 51, a numeric keypad 52, and the like (see FIG. 2). The user inputs to the operation unit 50 and operates the image forming apparatus 100 such as using the number of copies to be printed or a desired function (double-sided printing function or the like) of the image forming apparatus 100.

  The image reading unit 6 reads a document image to be copied, and includes a contact glass 20 provided at the uppermost part of the apparatus main body 1 and an optical system unit 21 provided therebelow. The contact glass 20 includes a contact glass 20a disposed at an image reading position for reading a document sent from the document conveying device 8, and a contact glass 20b on which a user places the document by opening and closing the document conveying device 8 upward. It is made up of. The optical system unit 21 irradiates the original passing through the contact glass 20a or the original placed on the contact glass 20b, and the reflected light is reflected by the mirror and the imaging lens in the optical system unit 21. The document image read and input to a CCD (Charge Coupled Device) is converted into data.

  In the sheet conveyance path 7, the sheet P picked up from the sheet feeding units 4 a to 4 d passes through the image forming unit 2 and the fixing device 3 and is discharged from the discharging unit 23 formed on the side surface of the image forming apparatus 100. It is formed to be discharged. Further, the sheet conveyance path 7 in the image forming apparatus 100 of the present invention includes a double-side conveyance path 25 so that the sheet P that has passed through the fixing apparatus 3 can be conveyed and circulated again upstream in the conveyance direction of the fixing apparatus 3. . More specifically, the paper P that has passed through the fixing device 3 is transported again upstream of the paper transport of the image forming unit 2.

  The choice of whether to discharge the paper P as it is to the discharge tray 9 or to circulate using the double-sided conveyance path 25 is provided downstream of the fixing device 3 in the conveyance direction and between the discharge unit 23. This is performed by the switching guide 26. A plurality of transport roller pairs 27 are arranged along the paper transport path 7 and the double-side transport path 25, and the transport roller pairs 27 transport the paper P in a predetermined direction by a driving device (not shown). Is driven to rotate.

  A double-sided printing tray 28 is provided in the middle of the double-sided conveyance path 25 that circulates the paper P. When performing duplex printing, the paper P is switched back on the duplex printing tray 28. Specifically, the paper P guided to the double-sided conveyance path 25 by the switching guide 26 is provided close to one end portion of the double-sided printing tray 28, and is rotated in a forward and reverse direction by a driving device (not shown). The sheet is pushed onto the duplex printing tray 28 by the driveable switchback roller pair 29.

  However, the switchback roller pair 29 does not completely push the paper P onto the double-sided printing tray 28, but rotates in the reverse direction while holding the rear end of the paper P. When the paper P is pulled out from the double-sided printing tray 28 by this reverse rotation, the paper P is conveyed in the direction of the image forming unit 2 with the front and back reversed. If the transport roller pair 27 provided in the discharge unit 23 is a copier that can rotate forward and backward, the discharge unit 23 may be switched back.

  FIG. 2 is an external perspective view of the image forming apparatus of the present invention. In FIG. 2, the description of the document conveying device 8 and the discharge tray 9 is omitted, and portions common to those in FIG. As shown in FIG. 2, two rod-like gripping members 30 are provided on the right side surface 1 a of the apparatus main body 1 at a substantially central portion in the height direction. The rod-shaped gripping member 30 is fixed to the frame of the apparatus main body 1 via a support rail 31 (see FIG. 3), and can be moved in and out of the right side surface 1a by sliding along the support rail 31. It has become. Although not shown here, two bar-shaped gripping members 30 are also provided on the left side surface 1b of the apparatus main body 1 so as to be able to be taken in and out at positions symmetrical to the right side surface 1a.

  Next, the configuration of the rod-shaped gripping member and the support rail will be described. 3 and 4 are side views of the rod-like gripping member and the support rail as seen from the inside and outside of the apparatus, respectively, FIG. 5 is a plan view of the rod-like gripping member and the support rail as seen from above, and FIG. AA arrow sectional drawing, FIG. 7 is the figure which looked at the rod-shaped holding member and the support rail from the right direction of FIG. In FIGS. 4 and 6, since FIG. 3 is inverted in the vertical direction, the top and bottom of FIG. 3 are reversed. Further, in the following description, the rod-like gripping member 30 and the support rail 31 provided on the front side of the right side surface 1a are illustrated, but the rod-like gripping member 30 and the support rail 31 provided at other positions are all the same configuration. Therefore, the description is omitted.

  The support rail 31 is a sheet metal member formed by bending a steel plate into a substantially U-shaped cross section, and a long hole 33 extending in the sliding direction (arrow BB ′ direction) of the rod-shaped gripping member 30 is formed on the side surface. A positioning piece 31a for attaching the support rail 31 to the side surfaces 1a and 1b (see FIG. 2) of the image forming apparatus 100 is formed at the tip. Further, a lock pin 35 that protrudes downward is attached to the upper side of the apparatus on the upper side of the support rail 31 (on the right side in FIG. 3). The rod-shaped gripping member 30 is formed by bending a steel plate into a substantially rectangular shape with a cut corner, and a plurality of through holes 37a to 37d arranged in a straight line along the longitudinal direction are provided on the outer peripheral surface. The through holes 37a to 37d are formed at the same time when the steel sheet is punched before being bent.

  A sliding pin 39 is fixed from the outside through an elongated hole 33 of the support rail 31 to an end portion (left end in FIG. 4) of the rod-shaped gripping member 30 inside the apparatus. The sliding pin 39 is composed of a head portion 39a and a shaft portion 39b. The shaft portion 39b slides in the elongated hole 33, so that the rod-shaped gripping member 30 slides with respect to the support rail 31 in the range of the elongated hole 33. It is supported movably. Specifically, the sliding pin 39 moves to the right end of the long hole 33 in FIG.

  On the other hand, the sliding pin 39 moves to the left end of the elongated hole 33 in a state where the rod-shaped gripping member 30 is completely pushed into the apparatus. Thereby, it is possible to prevent the rod-shaped gripping member 30 from coming off from the support rail 31 when the rod-shaped gripping member 30 is pulled out from the apparatus main body or pushed into the apparatus main body. Further, since the diameter of the head portion 39a of the sliding pin 39 is larger than the width of the elongated hole 33, there is no possibility that the rod-like gripping member 30 is disengaged in the opening direction (left direction in FIG. 7) of the side surface of the support rail 31.

  Further, when the bar-shaped gripping member 30 is in a horizontal state, the dimension is set so that there is a slight gap between the upper surface of the bar-shaped gripping member 30 and the support rail 31 and the lock pin 35 is not in contact. . The material of the rod-shaped gripping member 30 is not limited to the steel plate described above, and a metal plate that can ensure a desired strength can be used.

  8 and 9 are a side view and a cross-sectional view showing a state in which the bar-shaped gripping member is gripped and lifted, and FIG. 10 is a view of the bar-shaped gripping member and the support rail as viewed from the right in FIG. A method of using the rod-shaped gripping member 30 when transporting the image forming apparatus will be described with reference to FIGS.

  Normally, the rod-shaped gripping member 30 is in a stored state pushed into the apparatus. An operator who carries out the transportation or the like holds the end of the rod-shaped gripping member 30 from the stored state and pulls it out in the horizontal direction (arrow B direction). At this time, if there is sufficient space around the image forming apparatus, the rod-shaped gripping member 30 is pulled out to the maximum pulling position. When the space is limited, the rod-shaped gripping member 30 is pulled out by a predetermined length that can be pulled out.

  Next, the operator grips the pulled bar-shaped gripping member 30, and lifts and tilts the bar-shaped gripping member 30 in the direction of arrow C as shown in FIGS. Then, the clearance gap between the upper surface of the rod-shaped holding member 30 and the support rail 31 becomes narrow. At this time, when any of the plurality of through holes 37 c formed on the upper surface of the rod-shaped gripping member 30 overlaps with the lock pin 35, the lock pin 35 and the through hole 37 c are fitted. Further, depending on the pull-out amount of the rod-shaped gripping member 30, the positions of the lock pin 35 and the through hole 37c may not overlap each other. In that case, the rod-shaped gripping member 30 is slid in the arrow B direction while being lifted. The lock pin 35 is fitted into the through hole 37c located closest to the inside.

  That is, the lock pin 35 is fitted into one of the plurality of through holes 37 c formed on the upper surface of the rod-shaped gripping member 30 regardless of the amount of pulling out of the rod-shaped gripping member 30, and the sliding of the rod-shaped gripping member 30 is restricted. . Therefore, since the rod-shaped gripping member 30 does not slide when the rod-shaped gripping member 30 is lifted, a stable gripping state can be maintained.

  Then, the image forming apparatus is lifted by holding the rod-shaped holding member 30, or the image forming apparatus is pulled and transported to a desired installation location. Since the through holes 37a to 37d are formed in the upper surface, the side surface, and the lower surface of the rod-shaped gripping member 30, fingers can easily bite into the through holes 37a to 37d, and a high anti-slip effect is exhibited. Accordingly, it is possible to safely perform work especially when a large image forming apparatus is routed to be transported and moved. Further, the weight of the rod-shaped gripping member 30 can be reduced by the amount of the through holes 37a to 37d, which contributes to the weight reduction of the image forming apparatus.

  When transportation of the image forming apparatus is completed and the hand is released from the rod-shaped gripping member 30, the rod-shaped gripping member 30 returns to the horizontal state (see FIG. 3), and the fitting between the lock pin 35 and the through hole 37c is easily released. The Thereafter, the rod-shaped gripping member 30 is pushed in the horizontal direction (in the direction of the arrow B ′) along the support rail 31 and stored in the apparatus.

  According to this embodiment, since the rod-shaped holding member 30 is formed by bending a metal plate, the cost can be reduced. Further, since the through holes 37a to 37d for slip prevention are also integrally formed by punching the metal plate, the slip stopper can be produced simultaneously with the punching of the metal plate forming the rod-shaped gripping member 30, and the workability is improved. It can be formed, and substantial weight reduction can be achieved. Further, since the rod-like gripping member 30 is formed in a square tube shape with a corner dropped, it is easy to hold and strong in strength.

  Furthermore, when the bar-shaped gripping member 30 is pulled out and lifted, the bar-shaped gripping member 30 can be fixed in multiple stages according to the amount of pull-out from the apparatus main body, and the operability during transporting the apparatus is improved.

  The number and arrangement of the through holes 37a to 37d are not particularly limited, but in order to obtain an anti-slip effect when any portion of the rod-shaped gripping member 30 is gripped, a predetermined interval is provided over substantially the entire longitudinal direction. It is preferable to form a plurality. In addition, if the through holes 37a to 37d are too small, fingers do not easily bite and the desired anti-slip effect cannot be obtained. Conversely, if the through-holes 37a to 37d are too large, the strength of the rod-shaped gripping member 30 may be reduced. The shape and size may be set in consideration of the member strength. Furthermore, the through holes 37 c formed on the upper surface of the rod-shaped gripping member 30 need to be formed so as to be aligned in a straight line so that each through hole 37 c can be securely fitted to the lock pin 35.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above embodiment, the through-holes 37a and 37b are formed on both side surfaces of the rod-shaped gripping member 30, the through-hole 37c is formed on the top surface, and the through-hole 37d is formed on the bottom surface. The through holes 37 a to 37 d may be formed on at least one surface of the member 30. In order to obtain a sufficient anti-slip effect, it is preferable to form through holes 37 a and 37 b on at least both side surfaces of the rod-shaped gripping member 30.

  Moreover, in the said embodiment, although the cross-sectional shape of the rod-shaped holding member 30 was formed in square cylinder shape, for example, you may make it polygonal cylinder shape, such as a triangle and a pentagon, or you may make it cylindrical. Further, the cross-sectional shape of the support rail 31 may be appropriately changed according to the cross-sectional shape of the rod-shaped gripping member 30. However, in the case of a cylindrical shape, the rod-shaped gripping member 30 is rotated and the positional relationship between the lock pin 35 and the through hole 37c is easily shifted. Such a rotation-preventing concave portion and convex portion may be provided.

  Moreover, the rod-shaped holding member 30 can also be formed in a U-shaped cross section. In this case, if the rod-shaped gripping member 30 is used in a state where it is always pulled out to the maximum, the engagement between the lock pin 35 and the through hole 37c becomes unnecessary, so the rod-shaped gripping member 30 has three surfaces excluding the top surface. It may have a structure.

  The present invention is not limited to the monochrome copying machine shown in FIG. 1, but is a digital multifunction machine, an analog copying machine, a monochrome printer, a color copying machine or a color printer that forms a color image by sequentially laminating toner images of respective colors. Needless to say, the present invention can be applied to various types of image forming apparatuses such as facsimiles.

  The present invention can be used for an image forming apparatus provided with a rod-like gripping member for transportation and movement.
