  (First embodiment)

  FIG. 1 is a configuration diagram of an image forming apparatus 1 according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of a main part of an image forming unit of the image forming apparatus 1 of FIG.

  The image forming apparatus 1 has a function of printing an image on a sheet (an example of a recording medium) P, such as a copier, a printer, a facsimile, or a multifunction machine having both functions. A paper unit 3, an image forming mechanism unit 4, and a paper discharge unit 5 are provided.

  The image processing unit 2 is a circuit unit that performs predetermined image processing such as A / D conversion, density correction, and shading correction on image information input from the outside. The image processing unit 2 includes, for example, image information sent from a host computer such as a personal computer, image information sent via a communication line such as a LAN (Local Area Network), a telephone line, or the Internet, or Image information read by the image reading device is input.

  The paper feed unit 3 has a function of supplying the paper P to the image forming mechanism unit 4, and includes a plurality of paper cassettes 6, a feed roll 7a, and a resist roll pair 7b. A broken line CL in FIG. 1 indicates the conveyance path of the paper P.

  Each paper cassette 6 contains a plurality of different types of paper P such as paper size, thickness or paper quality. Any one sheet P of the plurality of sheet cassettes 6 is extracted one by one by a feed roll 7a and sent to a registration roll pair 7b through a conveyance path CL, where image formation is performed in accordance with the timing of toner image transfer. It is sent to the mechanism unit 4.

  The image forming mechanism unit 4 has a function of printing an image on the paper P sent from the paper feeding unit 3 by electrophotographic technology based on the image information sent from the image processing unit 2. An example of an image carrier 8, a charging roll 9, an exposure unit 10, a developing roll 11, a transfer roll (an example of a transfer unit) 12, a cleaner blade 13, and a fixing unit (an example of a fixing unit) 14 And a sheet peeling unit (an example of a recording medium guide member) 15. Among these, the photosensitive drum 8, the charging roll 9, the developing roll (an example of a developing unit) 11, the cleaner blade 13, and the paper peeling unit 15 can be integrally handled as an image forming body.

  The photosensitive drum 8 is formed by providing a photosensitive layer such as an organic photoconductor (OPC) or amorphous silicon on the outer peripheral surface of a conductive cylindrical drum base made of aluminum, for example. As shown by the arrows, it is supported so as to be rotatable clockwise.

  The charging roll 9 has a function of charging the surface of the photosensitive drum 8 to a predetermined polarity and potential when a charging bias is applied, and is installed in the vicinity of the photosensitive drum 8.

  The exposure unit 10 has a function of irradiating the surface of the photosensitive drum 8 charged by the charging roll 9 by irradiating the laser beam LB, and removing the charge of the exposed portion to form an electrostatic latent image. A laser oscillator (not shown), a rotary polygon mirror 10a, and reflection mirrors 10b and 10c are provided. The laser oscillator is a light source of the laser beam LB, and is on / off controlled based on image information sent from the image processing unit 2. The laser beam LB emitted from the laser oscillator is deflected and scanned by the rotary polygon mirror 10a, and is irradiated onto the surface of the photosensitive drum 8 through the reflection mirrors 10b and 10c.

  The developing roll 11 has a function of applying a toner (an example of a developer) to the electrostatic latent image on the surface of the photosensitive drum 8 to develop it as a toner image. The roller 9 is disposed downstream of the roll 9 in the rotation direction of the photosensitive drum 8 so as to be rotatable counterclockwise. By applying a developing bias to the developing roll 11, the toner adheres to the electrostatic latent image on the surface of the photosensitive drum 8 and is developed as a toner image.

  The transfer roll 12 has a function of transferring a toner image formed on the surface of the photosensitive drum 8 onto the paper P, and is more in contact with the photosensitive drum 8 than the developing roll 11 so as to come into contact with the photosensitive drum 8. It is installed downstream in the rotational direction. A transfer bias having a polarity opposite to the polarity of the toner image on the surface of the photosensitive drum 8 is applied to the transfer roll 12, whereby the toner image on the surface of the photosensitive drum 8 is transferred onto the paper P. The facing portion between the photosensitive drum 8 and the transfer roll 12 is a transfer position. The residual toner on the surface of the photosensitive drum 8 after the transfer process is removed and collected by the cleaner blade 13.

  The fixing unit 14 has a function of fixing the toner image to the paper P by applying heat and pressure to the paper P on which the toner image has been transferred. And a pressure roll 14b. The paper P on which the toner image has been fixed by the fixing unit 14 is discharged onto a paper discharge tray 5 b of the paper discharge unit 5 by a paper discharge roll pair 5 a of the paper discharge unit 5.

  The sheet peeling unit 15 is provided between the transfer position where the toner image on the photosensitive drum 8 is transferred by the transfer roll 12 and the fixing unit 14 and on the side facing the toner image transfer surface of the sheet P. In order to stably cope with the sheet P of the type (size) corresponding to the apparatus 1 and the transport direction (longitudinal direction, lateral direction), they are separated from each other along the axial direction of the photosensitive drum 8 (width direction of the sheet P). Two are installed in the state. However, the number of the sheet peeling units 15 is not limited to this, and may be three or more.

  Each sheet peeling unit 15 includes a support 15a, a peeling claw 15b, and a wheel (an example of a rotating member) 15c. Thus, by providing the peeling claw 15b and the wheel 15c on the same support 15a, the configuration is simplified, and the design space and the number of manufacturing steps are reduced. Further, since the peeling claw 15b and the wheel 15c can be handled integrally as the paper peeling unit 15, workability such as assembly, disassembly and maintenance of the image forming apparatus 1 is improved. Further, since the mutual positional accuracy between the peeling claw 15b and the wheel 15c is improved, the paper P is transported more favorably downstream.

  Here, FIG. 3 is an overall perspective view of the sheet peeling unit 15, and FIG. 4 is a side view of the sheet peeling unit 15. In FIGS. 3 and 4, the inside of the sheet peeling unit 15 is shown through in order to make the components easy to see. Hereinafter, the sheet peeling unit 15 will be described in detail with reference to FIGS.

  The peeling claw 15b is a member that peels off the paper P attached to the photosensitive drum 8 so that the paper P after transfer of the toner image is not wound around the photosensitive drum 8, and is shown in FIGS. 4 is supported by the support 15a so as to slightly swing in the radial direction of the photosensitive drum 8 around the rotation shaft portion 15ba of the peeling claw 15b shown in FIG.

  A tension coil spring 15d is attached between the rear end of the peeling claw 15b and the connecting column portion 15aa of the support 15a, and the peeling claw 15b is pulled by the tension coil spring 15d to pull the peeling claw. The tip of 15 b is pressed so as to contact the surface of the photosensitive drum 8.

  The wheel 15c is a member that guides the paper P after transfer of the toner image downstream in the conveyance direction, and is centered on the rotary shaft 15ca at a position further away from the transfer position of the toner image than the peeling claw 15b downstream in the conveyance direction. It is supported by the support 15a in a rotatable state.

  For example, a star wheel is used as the wheel 15c. A plurality of tapered protrusions 15cb are formed on the outer periphery of the wheel 15c. The reason for using the star wheel is to reduce the contact area with the paper P. That is, the toner adhering to the protrusions 15cb does not damage the toner image on the paper P even if the plurality of protrusions 15cb on the outer periphery of the wheel 15c directly contact the transfer surface of the unfixed toner image on the paper P. This is to reduce the amount of toner and reduce the visibility of the toner adhering to the non-image portion of the paper P. From this viewpoint, the tips of the plurality of protrusions 15cb on the outer periphery of the wheel 15c are thin and sharp.

  Here, if the sharp protrusion 15cb of the wheel 15c protrudes, the wheel 15c has a sharp protrusion as described above when the image forming apparatus 1 is assembled, disassembled, maintained, or the like. It is necessary to be careful not to touch it and to avoid touching it, which is a laborious and time-consuming work.

  In Patent Document 2, the paper peeling claw includes a claw body that peels the paper from the photosensitive drum, and a rotating member that guides the peeled paper to the fixing unit, and between the transfer unit and the fixing unit. When the paper being transported is under tension, the rotating member receives a component force from the paper in a direction perpendicular to the tension, retreats in the direction of the component force, and the addition of the component force is released. When it is done, the structure which returns to the original state is disclosed. In the case of this patent document 2, the rotating member is configured to retreat, but when a large load is applied to the rotating member, a reaction force is applied to the nail member on the counter electrode side and the rotating member is separated from the surface of the photoreceptor. In order to prevent this, the force applied to the rotating member is released, and it is necessary to hold the sheet because of the existence of the rotating member, and the tip of the contact portion of the rotating member must protrude from the holder. Therefore, the workability / safety is not improved.

  Thus, in the present embodiment, when a load greater than a predetermined value is applied to the wheel 15c, the entire wheel 15c moves so as to enter inside the outer periphery of the support 15a, while the load is released. The wheel 15c is supported by the support 15a so that the wheel 15c returns to its original position. As a result, when the wheel 15c is pushed during operations such as assembly, disassembly, and maintenance of the image forming apparatus 1, the operator hides inside the support 15a. No need to pay attention to. For this reason, work becomes easy and work time becomes short.

  As shown in FIGS. 3 and 4, the wheel 15c has a rotating shaft portion 15ca fitted into a guide groove 15ab extending inward from the outer periphery of the support 15a, and the direction in which the guide groove 15ab extends (the arrow in FIG. 4). (In the left-right direction indicated by X).

  Further, as shown in FIG. 4, the wheel 15c is moved outwardly of the support 15a by an torsion spring (an example of a support member) 15e attached between the peeling claw 15b and the wheel 15c inside the support 15a. It is pressed toward the left of the arrow X in FIG. The torsion spring 15e, also called a torsion spring, is fixed by fitting a ring portion at the center thereof into a protrusion 15ac inside the support body 15a. One end of the torsion spring 15e is stopped so as to be hooked on the rotating shaft portion 15ca of the wheel 15c, and the other end is stopped so as to be hooked on the rotating shaft portion 15ba of the peeling claw 15b. When the torsion spring 15e is used, the movable structure of the wheel 15c is simplified, and the design space and the manufacturing process are reduced. The torsion springs 15e are preferably provided on both sides in the width direction of the wheel 15c from the viewpoint of stably pressing the wheel 15c.

  Next, the operation of the sheet peeling unit 15 will be described with reference to FIGS.

  5 and 6 show the state of the paper P during normal conveyance. As shown in FIG. 5, the paper P is fed between the photosensitive drum 8 and the transfer roll 12 (transfer position) along the film-like chute 20, where the toner on the surface of the photosensitive drum 8 is transferred. The image is transferred to the surface of the paper P. Subsequently, the paper P is sent to the fixing unit 14 along the conveyance guide portion 21 where the toner image on the paper P is fixed. As shown in FIG. 6, the trailing edge of the paper P does not contact the paper peeling unit 15 when the leading edge of the paper P is sandwiched between the heating roll 14 a and the pressure roll 14 b of the fixing unit 14.

  On the other hand, the sheet P may be normally conveyed as described above, but the sheet P after the transfer of the toner image may be wound around the photosensitive drum 8. For example, the paper P may be wound around the photosensitive drum 8 when the paper P is thin or water-containing paper. When the paper P is thin, (the waist of the paper P) <(the electrostatic tacking force of the photosensitive drum 8), and the paper P may stick to the photosensitive drum 8 due to electrostatic action. In addition, when the paper P is water-containing paper, the paper may be curled and wound around the photosensitive drum 8 due to paper curl due to water content or curl after printing the first side during double-sided printing.

  In these cases, the paper P wound around the photosensitive drum 8 is peeled off by the peeling claw 15b of the paper peeling unit 15, and then guided to the fixing unit 14 in a point contact state by the wheel 15c. In this case, although the wheel 15c rotates as the paper P is conveyed, the wheel 15c is pressed outward from the support 15a by the torsion spring 15e (see FIG. 4), and is pressed from the paper P being conveyed. However, it does not get inside the support 15a.

  Next, FIGS. 7 to 9 show a case where the paper P being conveyed is distorted toward the paper peeling unit 15. As shown in FIG. 7, the center of the paper P may be bent toward the paper peeling unit 15 between the photosensitive drum 8 (transfer position) and the fixing unit 14. The main cause is, for example, when the rotational speeds of the transfer roll 12 and the fixing unit 14 (the heating roll 14a and the pressure roll 14b) are inconsistent and the paper P is stretched, or the paper P is distorted due to stretching of the fixing unit 14. May be bent toward the sheet peeling unit 15 side.

  Further, as shown in FIGS. 8 and 9, the rear end of the paper P may be bent toward the paper peeling unit 15 side. The main cause is that, for example, when the rear end of the paper P is released from the holding state of the transfer roll 12, the paper P may be bent by the spreading of the fixing unit 14 and bend to the paper peeling unit 15 side. A two-dot chain line Nf in FIG. 9 indicates the holding position of the paper P in the fixing unit 14.

  In these cases, the sheet P bent toward the sheet peeling unit 15 contacts the wheel 15c and is guided to the fixing unit 14 in a point contact state. In this case, although the wheel 15c rotates as the paper P is conveyed, the wheel 15c is pressed outward from the support 15a by the torsion spring 15e (see FIG. 4), and is pressed from the paper P being conveyed. However, it does not get inside the support 15a.

  Therefore, even when the sheet P is bent toward the sheet peeling unit 15, the transfer surface of the unfixed toner image on the sheet P is in contact with the other members of the image forming mechanism unit 4, in particular, the photosensitive drum 8. Therefore, the unfixed toner image on the paper P is not disturbed, and conversely, the other members of the image forming mechanism section 4 are not stained. Although the dot-like marks of the protrusions 15cb of the wheel 15c remain on the transfer surface of the unfixed toner image on the paper P, the transfer surface of the unfixed toner image on the paper P remains on the other members of the image forming mechanism section 4 (especially peeling). Compared with the case of contacting the claw 15b), it is light and there is no problem.

  Next, FIGS. 10 and 11 show side views of the sheet peeling unit 15 during operations such as assembly, disassembly, and maintenance of the image forming apparatus 1. In FIGS. 10 and 11, the inside of the sheet peeling unit 15 is shown through in order to make the components easy to see.

  As shown in FIG. 10, the sheet peeling unit 15 is exposed to the front surface during operations such as assembly, disassembly, and maintenance of the image forming apparatus 1. In this state, when the operator presses the wheel 15c, a force larger than the force necessary to press the paper P being conveyed is applied to the wheel 15c in the direction indicated by the arrow XA.

  At this time, in the present embodiment, as shown in FIG. 11, the entire wheel 15c moves along the guide groove 15ab so as to enter the inside of the support 15a, and a sharp protrusion on the outer periphery of the wheel 15c. 15cb is hidden inside the support 15a. This eliminates the need for the operator to pay attention to the sharp protrusions 15cb on the outer periphery of the wheel 15c of the sheet peeling unit 15, thus making the work safe and easy and shortening the work time.

  On the other hand, when the operator releases the wheel 15c and the force applied to the wheel 15c is released, the wheel 15c moves along the guide groove 15ab by the restoring force of the torsion spring 15e as shown in FIG. Return to the original position.

  (Second Embodiment)

  The ends of the arm portions 15ga and 15ga of the wheel support 15g are branched in a Y shape, and the left and right rotation shaft portions 15ca of the wheel 15c are supported in a rotatable state by the branched portions.

  Further, a compression coil spring 15f is provided between the opposing surfaces of the base portion 15gb of the wheel support 15g and the support 15a, whereby both the rotary shaft portions 15ca and 15ca of the wheel 15c are both arm portions 15ga, 15ga is pressed toward the outside of the support 15a, and the wheel 15c is pressed toward the outside of the support 15a.

  Also in this case, when a load greater than a predetermined value is applied to the wheel 15c in the same manner as in the first embodiment, the entire wheel 15c extends along the guide groove 15ab so as to enter inside the outer periphery of the support 15a. On the other hand, when the load is released, the position of the wheel 15c returns to the original position by the restoring force of the compression coil spring.
