A relay transfer device that transfers to a post-processing device attached to the forming apparatus main body. The relay conveyance device is provided with a fixing member that holds the mounting state of the relay conveyance device on the image forming apparatus main body, and the fixing member relays the image forming apparatus main body and the post-processing apparatus. A relay connector is provided, and the post-processing apparatus is electrically connected to the image forming apparatus main body via the relay connector.

  According to this configuration, since the relay connector provided on the fixing member is used, the harness processing is unnecessary, and the setup time of the relay conveyance device is shortened accordingly.

  In this case, the fixing member is pivotally supported on the rear end surface of the relay transport device in the mounting direction so as to be pivotable in the vertical direction along the rear end surface. While being stored in the rear end surface in the direction so as not to protrude from the rear end surface, the relay transport device protrudes from the rear end surface in the mounting direction of the relay transport device in a vertical posture rotated downward when mounted on the image forming apparatus main body. It is preferably fastened to the image forming apparatus main body.

  According to this configuration, since the fixing member does not protrude from the rear end face in the mounting direction of the relay conveyance device in the retracted state, it can be packed in a small space.

  In addition, an engaging portion is provided on one of the fixing member and the rear end surface in the mounting direction of the relay conveyance device, and an engaged portion is provided on the other. It is preferable that engagement / disengagement with the engaging portion is performed.

  According to this configuration, the storage state of the fixing member is stabilized at the time of packing, while the setup posture of the relay conveyance device is quickly prepared.

This connector is fitted to the main body connector 253 (see FIGS. 4 and 5) exposed from the standing wall portion 255 of the right connection housing portion 250b when the relay transport device 300 is mounted on the paper tray 101, and the relay transport device. 300 and the image forming apparatus main body 1 are electrically connected.

  On the left side wall (rear end surface in the mounting direction) of the relay conveyance device 300, as shown in FIGS. 6 to 14, one end side of the fixing member 310 that holds the mounting state of the relay conveyance device 300 to the image forming apparatus main body 1 is provided. A cylindrical shaft portion 305 having a C-shaped cross section is pivotally supported so as to be rotatable in the vertical direction along the left side wall of the relay conveyance device 300.

  The fixing member 310 is configured by combining a base material 311 on the back side (right side of the image forming apparatus main body 1) and a cover material 312 on the front side (left side of the image forming apparatus main body 1). The base material 311 is formed of a sheet metal member, and a shaft hole 311 a into which the cylindrical shaft portion 305 is inserted is formed on one end side of the base material 311. Furthermore, the base material 311 is formed with a long hole 311b that is continuously connected to the edge of the shaft hole 311a via the communication portion 311d. An engaging portion 311c (see FIG. 11) for fixing the base material 311 is formed at one end of the base material 311 and the other opposite end. In addition, a connecting plate 318 stands on the side of the post-processing device 400 from one end of the base material 311 in the width direction (a direction orthogonal to the longitudinal direction). The connecting plate 318 is formed by bending a sheet metal at a right angle. On the other end side of the base material 311, a relay connector 313 that relays between the image forming apparatus main body 1 and the post-processing apparatus 400 is provided so as to be exposed from the cover material 312. An opening 312a is formed on the other end side of the cover material 312 so that the relay connector 313 is exposed to the outside. In the fixing member 310, an end portion on the extension side of the harness 316 extending from the relay conveyance device 300 to the outside of the device 300 is accommodated. One end of the harness 316 is connected to the input connector 317. The end of the harness 316 on the extending side is accommodated in the fixing member 310 via the cylindrical shaft portion 305 and the shaft hole 311a and connected to the relay connector 313.

  The fixing member 310 is assembled in the following procedure. First, the relay connector 313 connected to the harness 316 extending from the relay conveyance device 300 is inserted into the long hole 311b (see FIG. 12) of the base material 311, and then the harness 316 is passed from the long hole 311b through the communication portion 311d.

The ground member 258 is formed of a thin metal plate having elasticity, and one end thereof is fastened to the metal frame of the main body casing 100. The other end of the ground member 258 protrudes inward of the positioning hole 256. When the relay conveyance device 300 is attached to the image forming apparatus main body 1, the positioning guide 320 is inserted into the positioning hole 256 and comes into contact with the other end of the ground member 258. As a result, the relay conveyance device 300 is grounded via the main body casing 100.

  A screw insertion hole 315 (corresponding to a first insertion hole; see FIGS. 7, 9 and 13) is formed in the vicinity of the engagement hole 314 of the fixing member 310 (base material 311).

  Then, the fixing member 310 is stored in a horizontal posture rotated upward at the time of packing so as not to protrude from the rear end surface on the rear end surface in the mounting direction of the relay conveyance device 300 (see FIGS. 6 and 7). On the other hand, when the relay conveyance device 300 is attached to the image forming apparatus main body 1 (at the time of setup), the relay conveyance device 300 is first placed on the paper tray 101 of the image forming apparatus main body 1 as shown in FIG. As shown in FIG. 12, the fixing member 310 is once lifted to disengage the engaging claw 306 from the engaging hole 314. Next, the fixing member 310 is protruded from the rear end surface in the mounting direction of the relay conveyance device 300 in a state where the fixing member 310 is held in a vertically rotated posture (see FIGS. 8, 9, 13, and 14). Thereafter, the relay conveyance device 300 is pushed upstream in the paper discharge direction, and the input connector 317 on the front side in the mounting direction of the relay conveyance device 300 is connected to the main body connector 253 of the image forming apparatus main body 1 (see FIGS. 4 and 5). Then, the relay conveyance device 300 and the image forming apparatus main body 1 are electrically connected. At this time, the positioning guide 320 is engaged with the positioning hole 256 to restrict the horizontal position. Thereby, since the input connector 317 is positioned with respect to the main body connector 253, both can be connected easily. Further, the positioning guide 320 is fitted into the positioning hole 257 and the engaging protrusion 321 is fitted into the engaging recess 257 so that the front end side in the mounting direction of the relay conveyance device 300 is moved up and down with respect to the main body housing unit 100.
