- the support portion 281 is formed in the guide member 28 in a groove shape including a long bottom surface in the sub-scanning direction 213 and two side walls erected on the bottom surface. Accordingly, the upper portion 272 of the cable 27 is supported between the first reading unit 22 and the second reading unit 23 so as not to hang downward. Further, the movement of the cable 27 in the main scanning direction 214 is limited by the side wall of the support portion 281.
- the structure in which the said support part 281 contains the several side wall erected intermittently along the said subscanning direction 213 is considered as other embodiment.
- a configuration in which the support portion 281 includes a bottom surface having openings intermittently along the sub-scanning direction 213 is also conceivable.
- the support part 281 has a protrusion part 282 that protrudes inward from one or both of the two side walls and forms an opening having a width narrower than the width of the cable 27 at the upper part of the support part 281.
- the vertical movement of the cable 27 is restricted by the protrusion 282, and the cable 27 is prevented from contacting the housing of the image forming apparatus 10.
- One or more guide support portions 283 are provided on the outer surface of the support portion 281 of the guide member 28, and support the guide member 28 horizontally.
- the guide support part 283 is formed to extend from the outer surface of the support part 281 in the main scanning direction 214 in a long shape.
- a long rib member 291 is provided on the inner wall 29 of the image reading unit 2 in the sub-scanning direction 213.
- the guide support portion 283 is supported by the rib member 291 so as to be movable in the horizontal direction. Thereby, it is suppressed that the front-end
- connection terminal of the cable 27 connected to the light source driving unit 221 ⁇ / b> A is restricted from moving upward in the support unit 281 by the protrusion 282. Therefore, the cable 27 is connected to the connection part 221B of the light source driving part 221A within the support part 281 of the guide member 28.
- the connection part 221 ⁇ / b> B is a connection terminal that extends downward from the light source driving part 221 ⁇ / b> A and is movable in the support part 281.
- the connection portion 221 ⁇ / b> B moves along the sub-scanning direction 213 in the support portion 281 of the guide member 28 as the first reading unit 22 moves.
- the upper portion 272 of the cable 27 is supported by the guide member 28 provided in the second reading unit 23 at a position separated from the first reading unit 22. Contact with the lower portion 273 is suppressed.
- the guide member 28 suppresses the contact between the upper portion 272 and the lower portion 273 of the cable 27, a sufficient interval is provided between the control unit 5 and the first reading unit 22 in the vertical direction. This is unnecessary, and the housing of the image forming apparatus 10 can be downsized.
