The restriction by the rotation restricting portion 45 is released by sliding at least one of the first substrate supporting portion 11 and the second substrate supporting portion 12. The rotation restricting portion 45 is provided near the shaft portion 7. In any of the image forming apparatuses described in the above embodiments, if the setting is made so that the substrate support can be rotated only after the substrate support is slid, the rotation is performed. The regulation part 45 can be adopted.

  FIG. 14 is an enlarged sectional view of the rotation restricting portion 45. FIG. 15 shows a top view. The shaft support 8 has a hole 6. In the example shown here, the hole 6 is a through hole, but need not be a through hole. The rotation restricting portion can also be realized by a concave portion that does not penetrate. FIG. 16 shows only the shape of the hole 6. The hole 6 includes a first space 6a and a second space 6b. The first space 6a is substantially circular. The second space 6b is linear. As shown in FIG. 16, the first space 6a and the second space 6b communicate with each other. As shown in FIG. 14, a vertically extending portion of the shaft portion 7 penetrates the hole 6. In the state shown in FIG. 14, the shaft portion 7 is located in the second space portion 6b, and in this state, the substrate supporting portion connected to the shaft portion 7 cannot rotate. As shown in FIG. 14 and FIG. 15, the shaft 7 moves to the first space 6 a by the movement of the shaft 7 as shown by the arrow 99, and as a result, the substrate supporting portion connected to the shaft 7 is It becomes pivotable. As shown in FIG. 15, the first space 6a has a diameter large enough to allow the shaft 7 to rotate inside. FIG. 17 is a cross-sectional view of the shaft 7 in the first space 6a as viewed from the side.

As a modification of the image forming apparatus according to the present embodiment, an image forming apparatus 107 shown in FIG. 19 can be considered. In the image forming apparatus 107, the mediation component is the harness 35. The first substrate support 11 and the second substrate support 12 each include a harness fixing part 36. In the example shown in FIG. 19, two harnesses 35 are used, but the number of harnesses 35 may be other than two. When there are a plurality of harnesses, the harnesses are not necessarily all the same length, and harnesses having different lengths may be used in combination.

  In order to reduce the influence of noise on the first substrate 31, it is preferable to directly connect the substrates. However, even if the substrates are separated from each other, it is possible to connect using the harness 35 in this manner. The first substrate 31 has a connector 27. The second substrate 32 has the connector 28. The harness 35 is arranged so as to connect the connector 27 and the connector 28. The passing position of the middle part of the harness 35 is regulated by the harness fixing part 36.

  By employing this configuration, the first substrate supporting portion 11 and the second substrate supporting portion 12 cannot be opened unless the harness 35 as an intermediate component is first removed. Removing the harness 35 is nothing but disconnecting the connection between the boards. Therefore, in the image forming apparatus 107, it is possible to prevent a worker from accidentally opening the first substrate support portion 11 and the second substrate support portion 12 in a state where the connection between the substrates is not released yet. it can.
