This improves the user operability.

(E) Fifth Embodiment An in-cylinder discharge type image forming apparatus according to a fifth embodiment that satisfies the following formula will be described with reference to FIGS.
0.6 ≧ La / Lb ≧ 0.3
La: The distance between the foremost front part of the first column part located at the rear and the position of the scanner part located at the front and the position of the foremost front part of the main body housing part. Lb: Distance from the lowest position of the paper discharge tray in the paper storage

  Conventionally, in such an in-body discharge type image forming apparatus, the positions of the front portions of the scanner unit 200, the main body housing unit 120, and the first support column unit 300 are the same or substantially the same, that is, approximately La = 0 to 0. 30 (mm), Lb = 200 to 400 (mm), and La / Lb = 0 to 0.15.

  Further, conventionally, there has been no technical idea that the above formula is established and the position of the front portion of the first support column 300 is set based on the range satisfying the formula. That is, the optimal position of the front portion of the first support column 300 is not determined by the value of (La / Lb).

  Therefore, by satisfying the above mathematical formula, in the operating state (a in FIG. 4), the forefront part of the first support column 300 is not visible and is in a slightly separated position (a in FIG. 4). The front part of the forefront of the first support column 300 is in a position where it can be clearly confirmed. For example, in the in-cylinder discharge type image forming apparatus of the fifth embodiment, La = 80 (mm), Lb = 200 (mm), and La / Lb = 0.4.

  That is, the user can feel the distance between the scanner unit 200 and the main body housing unit 120 because the front part of the front of the first support column unit 300 is not visible in the operating state (a in FIG. 4). .

  Here, in the case of (La / Lb) ≧ 0.6, the forefront portion of the first support column tends to be invisible at both positions a and b in FIG. Problems arise. In the case of (La / Lb) ≦ 0.3, the forefront portion of the first support column tends to be visible at both positions a and b in FIG. 120 and the first support post 300 have a sense of unity, making it difficult to remove the paper from the in-body discharge type space.

(F) Sixth Embodiment An in-cylinder discharge type image forming apparatus according to a sixth embodiment that satisfies the following formula will be described with reference to FIGS.
0.8 ≧ La / Lc ≧ 0.6
La: The distance between the foremost front part of the first column part located at the rear and the position of the scanner part located at the front and the position of the foremost front part of the main body housing part. Lc: Average distance from the paper discharge tray in the paper storage

For example, in the in-cylinder discharge type image forming apparatus of the sixth embodiment, La = 80 (mm), Lc = 1.
20 (mm) and La / Lc = 0.667. As in the fifth embodiment, by satisfying the above mathematical formula, in the operating state (a in FIG. 4), the forefront portion of the first support column 300 is not visible and is in a slightly separated position ( 4A), the forefront portion of the first support column 300 is in a position where it can be clearly confirmed.

  That is, the user can feel the distance between the scanner unit 200 and the main body housing unit 120 because the front part of the front of the first support column unit 300 is not visible in the operating state (a in FIG. 4). . In addition, when in a slightly separated position (a in FIG. 4), the front part of the forefront of the first support column 300 can be seen well, so that the scanner unit 200 and the main body housing unit 120 can feel unity. Can feel the strength of the entire device.

  Here, in the case of (La / Lc) ≧ 0.8, the forefront portion of the first support post 300 tends to become invisible at both positions a and b in FIG. Problems arise. In the case of (La / Lc) ≦ 0.6, the forefront portion of the first support column 300 tends to be visible at both positions a and b in FIG. Since the unit 120 and the first support column 300 have a sense of unity, it is difficult to remove the paper from the in-body discharge type space.
