Similarly, the second support column 400 supports the scanner unit 200 while standing on the main body housing unit 120 on the rear side of the image forming apparatus 100. As shown in FIGS. 1 and 2, when the image forming apparatus 100 is viewed from the front, the first support column 300 is disposed on the left side surface of the sheet storage unit, while the sheet is formed on the right side surface. The housing is open.

(A) 1st Embodiment 1st Embodiment by which the color of the part adjacent to a paper storage part among the main body housing part 120, the scanner part 200, and the 1st support | pillar part 300 was made darker than the color of another part. Will be described with reference to FIGS. Of the main body housing part 120, the scanner part 200, and the first column part 300, at least a part 600 adjacent to the paper storage part is darker than other parts, for example, the color of the paper cassette 121.

  A dark color means, for example, a low Munsell value defined by JIS, for example, a range of N1 to N2. Since the shadow of the storage space 500 and the color of the portion 600 adjacent to the paper storage portion are close to each other, the visibility of the storage space 500 is improved and the discharged transfer paper can be easily taken, that is, user operability. There is an effect of improving.

  In addition, since the paper storage unit is configured so that the discharged paper can be taken out from the direction in which the color difference can be recognized, the discharged transfer paper can be more easily taken. There is an effect of improving operability.

(B) Second Embodiment Of the main body housing part 120, the scanner part 200, and the first support post part 300, the color of at least the part adjacent to the paper storage part is darker than the color of other parts, and the Munsell chart (JIS) A second embodiment in which the difference in brightness in the Munsell value is 3 or more will be described with reference to FIGS. In the second embodiment, at least a portion 600 adjacent to the paper storage portion of the main body housing portion 120, the scanner portion 200, and the first support post portion 300 is darker than the other portions, for example, the color of the paper cassette 121, and Munsell The lightness difference in the Munsell value of the chart (JIS) is 3 or more.

  According to the second embodiment, the shadow of the storage space 500 and the color of the portion 600 adjacent to the paper storage portion are close to each other, and the difference in Munsell values from other portions, for example, the paper cassette 121 is 3 or more. Therefore, since the image of the portion 600 adjacent to the paper storage portion is separated from the other portions, the visibility of the storage space 500 is further improved, and the discharged transfer paper can be easily taken. There is an effect of improving the performance.

  In addition, since the paper storage unit is configured so that the discharged paper can be taken out from the direction in which the color difference can be recognized, the discharged transfer paper can be more easily taken. There is an effect of improving operability.

(C) Third Embodiment Of the main body housing part 120, the scanner part 200, and the first support post part 300, the color of at least the part adjacent to the paper storage part is set to 2 or less in the Munsell chart (JIS) Munsell value. A third embodiment will be described with reference to FIGS. In the third embodiment, the Munsell chart (JIS) Munsell chart (JIS) has a color of the portion 600 adjacent to the paper storage unit of 2 or less.

  According to the third embodiment, since the shadow of the storage space 500 and the color of the portion 600 adjacent to the paper storage portion are close to each other, the visibility of the storage space 500 is improved and the discharged transfer paper can be easily taken. In other words, there is an effect of improving user operability.

(D) Fourth Embodiment The color of the operation unit 210 provided in the scanner unit 200 is substantially the same as the color of the main body housing unit 120, the scanner unit 200, and the first support column unit 300 adjacent to the paper storage unit. An equivalent fourth embodiment will be described with reference to FIGS. In the fourth embodiment, the color of the operation unit 210 is substantially the same as the color of the portion 600 adjacent to the paper storage unit.

  According to the fourth embodiment, the portion 600 adjacent to the operation unit 210 and the paper storage unit is differentiated from other parts, for example, the paper cassette 121, and thus the visibility of the storage space 500 and the operation unit 210 is improved. 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 portion of the first support column located at the rear and the position of the scanner portion located at the front and the position of the forefront portion of the main body housing portion. Lb: The bottom surface of the scanner portion and the inside of the trunk. 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). . 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.

  More specifically, such an in-cylinder discharge type image forming apparatus has an image that the entire apparatus seems to be weak because there is a cavity in the in-cylinder discharge.

  Here, in the case of (La / Lb) ≧ 0.6, the front part of the forefront 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 foremost front part of the scanner housing and the 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 = 120 (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.
