Further, conventionally, there has been no technical idea that the above-described mathematical formula is established and optimum colors of the main body housing 400, the paper feed tray 500, and the front cover 600 are set based on a range that satisfies the mathematical formula.
That is, the side surface portion 410 of the main body housing is determined by the ratio of the maximum horizontal distance of the side surface portions 530 and 620 of the paper feed tray or the front cover to the maximum distance in the horizontal direction of the side surface portions 410 and 420 of the main body housing. , 420 and the side portions 530 and 620 of the paper feed tray or front cover have not been determined.

  Therefore, by satisfying the above mathematical formula, the paper feed tray pulled out from the apparatus main body to stack and store the paper in the paper feed tray, and the apparatus for removing the jammed paper when a paper jam or the like occurs inside the apparatus main body The discriminability between the front cover that opens and closes relative to the main body and the apparatus main body increases and the visibility is improved. That is, it is possible to easily recognize the size of the movable portion with respect to the apparatus main body, and to improve the user's operability and workability and to provide a safe image forming apparatus.

  This is because human beings are generally more conscious in the bright direction, and as a result, the focus of the eyes is shifted in the bright direction as well. In other words, since the consciousness concentrates on bright objects, if the color of the side surface of the image forming apparatus is as bright as the colors of the paper feed tray and the front cover, the consciousness is dispersed throughout the apparatus and the eyes If the focus shifts as a whole and the focus cannot be concentrated on the movable things such as the paper feed tray and the front cover, and the color of the side surface of the image forming apparatus is darker than the colors of the paper feed tray and the front cover, This is because the consciousness is concentrated on the paper feed tray and the front cover, and the focus of the eyes can be shifted and concentrated in the direction of the paper feed tray and the front cover.

  In addition, by making the side surface of the device main body darker, when opening and closing the open / close cover provided on the side surface of the device main body to remove the jammed paper, it was provided on the side surface of the device main body. The distinguishability between the inside of the apparatus main body that is visible when the opening / closing cover is opened and the jammed paper that is visible in that state and the side surface of the apparatus main body is increased, and the visibility is improved. This also has the effect of improving the user operability and workability and providing a safe image forming apparatus.

  This is also the same as above, and people tend to be more conscious in the direction of bright colors, and as a result, the focus of the eyes moves in the direction of bright colors. This is because consciousness concentrates on the color, and at the same time the focus of the eye moves in that direction. Accordingly, the user can concentrate his / her consciousness on the inside of the apparatus main body that is visible when the opening / closing cover provided on the side surface of the apparatus main body is opened and the jammed paper that is visible in that state.

  For example, when Bx = 4, By = 8, Lx = 630 (mm), and Ly = 30 (mm) are employed as the image forming apparatus of the present invention, (By−Bx) = 4, Lx / (7 XLy) = 3, which satisfies the above mathematical formula, the visibility of the paper feed tray 500 and the front cover 600 with respect to the main body housing 400 is improved, and the position can be clearly confirmed. Accordingly, there is an effect that the user operability can be improved and a safe image forming apparatus can be provided.

  That is, as the ratio of the maximum horizontal distance Ly in the side surface portions 530 and 620 of the paper feed tray or the front cover to the maximum horizontal distance Lx in the side surface portions 410 and 420 of the main body housing increases, the main body housing increases. Since the visibility of the paper feed tray 500 and the front cover 600 with respect to 400 is improved, the difference between the color of the main body housing 400 and the color of the paper feed tray 500 and the front cover 600 may be small.

  However, if (By-Bx) <3, the maximum distance in the substantially horizontal direction in the side portions 530 and 620 of the paper feed tray or the front cover with respect to the maximum horizontal distance Lx in the side portions 410 and 420 of the main body housing. Even if the ratio of Ly is large, the visibility of the paper feed tray 500 and the front cover 600 with respect to the main body housing 400 is lowered, so that it is difficult to confirm the position and the operability of the user is lowered.

Further, as the ratio of the maximum horizontal distance Ly in the side surface portions 530 and 620 of the paper feed tray or the front cover to the maximum horizontal distance Lx in the side surface portions 410 and 420 of the main body housing becomes smaller, the main body housing becomes smaller. Since the visibility of the paper feed tray 500 and the front cover 600 with respect to 400 is lowered, the difference between the color of the main body housing 400 and the color of the paper feed tray 500 and the front cover 600 must be increased.
However, since the lightness in the Munsell value of the Munsell chart (JIS) is defined by 0 to 10 in the standard, it is impossible that (By−Bx)> 10.

(J) Tenth Invention (Claim 10)
(By-Bx) ≧ Lx / (7 × Ly)
10.0 ≧ (By−Bx) ≧ 3.0
Bx = lightness on the side surface of the apparatus main body By = lightness on the side surface of the front cover Lx = maximum horizontal distance in the side surface of the apparatus main body Ly = maximum horizontal distance in the side surface of the front cover or paper feed tray The tenth invention of the image forming apparatus according to any one of claims 1 to 8, wherein the above formula is satisfied, will be described with reference to FIGS.
By adding the first to eighth inventions to the ninth invention, a paper feed tray that is pulled out from the apparatus main body in order to stack and accommodate sheets in the paper supply tray, and a paper jam or the like occurs inside the apparatus main body. In this case, the front cover that opens and closes with respect to the apparatus main body in order to remove the jammed paper and the apparatus main body can be distinguished from each other and the visibility can be improved. That is, it is possible to easily recognize the size of the movable portion with respect to the apparatus main body, and to improve the user's operability and workability and to provide a safe image forming apparatus.

  This is because human beings are generally more conscious in the bright direction, and as a result, the focus of the eyes is shifted in the bright direction as well. In other words, since the consciousness concentrates on bright objects, if the color of the side surface of the image forming apparatus is as bright as the colors of the paper feed tray and the front cover, the consciousness is dispersed throughout the apparatus and the eyes If the focus shifts as a whole and the focus cannot be concentrated on the movable things such as the paper feed tray and the front cover, and the color of the side surface of the image forming apparatus is darker than the colors of the paper feed tray and the front cover, This is because the consciousness is concentrated on the paper feed tray and the front cover, and the focus of the eyes can be shifted and concentrated in the direction of the paper feed tray and the front cover.

  In addition, by making the side surface of the device main body darker, when opening and closing the open / close cover provided on the side surface of the device main body to remove the jammed paper, it was provided on the side surface of the device main body. The distinguishability between the inside of the apparatus main body that is visible when the opening / closing cover is opened and the jammed paper that is visible in that state and the side surface of the apparatus main body is increased, and the visibility is improved. This also has the effect of improving the user operability and workability and providing a safe image forming apparatus.

  This is also the same as above, and people tend to be more conscious in the direction of bright colors, and as a result, the focus of the eyes moves in the direction of bright colors. This is because consciousness concentrates on the color, and at the same time the focus of the eye moves in that direction. Accordingly, the user can concentrate his / her consciousness on the inside of the apparatus main body that is visible when the opening / closing cover provided on the side surface of the apparatus main body is opened and the jammed paper that is visible in that state.

(K) Eleventh invention (Invention 11)
(Bz−Bv) ≧ Lz / (3 × 2 × Lv)
10.0 ≧ Bz−Bv ≧ 3.0
Bz = Lightness at the front face of the paper feed tray or front cover Bv = Lightness at the front edge of the apparatus main body Lz = Maximum horizontal distance at the front face of the paper feed tray or front cover Lv = At the front edge of the apparatus main body A maximum distance in a substantially horizontal direction An eleventh aspect of the image forming apparatus satisfying the above expression will be described with reference to FIGS.
Conventionally, in such an image forming apparatus, the colors of the main body housing 400, the paper feed tray 500, and the front cover 600 are the same or substantially the same.
Further, conventionally, there has been no technical idea that the above-described mathematical formula is established and optimum colors of the main body housing 400, the paper feed tray 500, and the front cover 600 are set based on a range that satisfies the mathematical formula.
That is, the front end portion 430 of the main body housing depends on the ratio of the maximum horizontal distance of the front portions 510 and 610 of the sheet feeding tray or the front cover to the maximum horizontal distance of the front end portion 430 of the main body housing. And the optimum color difference between the front side portions 510 and 610 of the paper feed tray or the front cover has not been determined.

  Therefore, by satisfying the above mathematical formula, the paper feed tray pulled out from the apparatus main body to stack and store the paper in the paper feed tray, and the apparatus for removing the jammed paper when a paper jam or the like occurs inside the apparatus main body The discriminability between the front cover that opens and closes relative to the main body and the apparatus main body increases and the visibility is improved. That is, it is possible to easily recognize the size of the movable portion with respect to the apparatus main body, and to improve the user's operability and workability and to provide a safe image forming apparatus.

  This is because human beings are generally more conscious in the bright direction, and as a result, the focus of the eyes is shifted in the bright direction as well. In other words, since the consciousness concentrates on bright objects, if the color of the side surface of the image forming apparatus is as bright as the colors of the paper feed tray and the front cover, the consciousness is dispersed throughout the apparatus and the eyes If the focus shifts as a whole and the focus cannot be concentrated on the movable things such as the paper feed tray and the front cover, and the color of the side surface of the image forming apparatus is darker than the colors of the paper feed tray and the front cover, This is because the consciousness is concentrated on the paper feed tray and the front cover, and the focus of the eyes can be shifted and concentrated in the direction of the paper feed tray and the front cover.

  In addition, by making the side surface of the device main body darker, when opening and closing the open / close cover provided on the side surface of the device main body to remove the jammed paper, it was provided on the side surface of the device main body. The distinguishability between the inside of the apparatus main body that is visible when the opening / closing cover is opened and the jammed paper that is visible in that state and the side surface of the apparatus main body is increased, and the visibility is improved. This also has the effect of improving the user operability and workability and providing a safe image forming apparatus.

  This is also the same as above, and people tend to be more conscious in the direction of bright colors, and as a result, the focus of the eyes moves in the direction of bright colors. This is because consciousness concentrates on the color, and at the same time the focus of the eye moves in that direction. Accordingly, the user can concentrate his / her consciousness on the inside of the apparatus main body that is visible when the opening / closing cover provided on the side surface of the apparatus main body is opened and the jammed paper that is visible in that state.

  For example, when Bz = 8, Bv = 4, Lz = 570 (mm), and Lv = 30 (mm) are adopted as the image forming apparatus of the present invention, (Bz−Bv) = 4, Lz / (3 × 2 × Lv) = 3.17, which satisfies the above mathematical formula, so that the visibility of the paper feed tray 500 and the front cover 600 with respect to the main body housing 400 is improved, and the position can be clearly confirmed. become. Accordingly, there is an effect that the user operability can be improved and a safe image forming apparatus can be provided.

  That is, as the proportion of the maximum horizontal distance Lz in the front surface portions 510 and 610 of the sheet feeding tray or the front cover to the maximum horizontal distance Lv in the front end 430 of the main body housing decreases, the main body housing 400 increases. Therefore, the difference between the color of the main body housing 400 and the color of the paper feed tray 500 and the front cover 600 may be small.

  However, when (Bz−Bv) <3, the maximum distance Lz in the substantially horizontal direction in the front surface portions 510 and 610 of the feed tray or the front cover with respect to the maximum horizontal distance Lv in the front end 430 of the main body housing. Even if the ratio occupied by the sheet is small, the visibility of the paper feed tray 500 and the front cover 600 with respect to the main body housing 400 is lowered, so that it is difficult to confirm the position, and the operability for the user is lowered.

Further, as the ratio of the maximum horizontal distance Lz in the front surface portions 510 and 610 of the paper feed tray or the front cover to the maximum horizontal distance Lv in the front end portion 430 of the main body housing increases, the main body housing 400 increases. Therefore, the difference between the color of the main body housing 400 and the color of the paper feed tray 500 and the front cover 600 must be increased.
However, the lightness at the Munsell value in the Munsell chart (JIS) is defined by 0 to 10 in the standard, and therefore it is impossible that (Bz−Bv)> 10.

(L) 12th invention (Claim 12)
(Bz−Bv) ≧ Lz / (3 × 2 × Lv)
10.0 ≧ Bz−Bv ≧ 3.0
Bz = Lightness at the front face of the paper feed tray or front cover Bv = Lightness at the front edge of the apparatus main body Lz = Maximum horizontal distance at the front face of the paper feed tray or front cover Lv = At the front edge of the apparatus main body The maximum distance in a substantially horizontal direction satisfies the above expression, and the twelfth invention of the image forming apparatus according to any one of claims 1 to 8 is described with reference to Figs. To do.
By adding the first to eighth inventions to the eleventh invention, a paper feed tray that is pulled out from the apparatus main body in order to stack and accommodate sheets in the paper supply tray, and a paper jam or the like inside the apparatus main body occur. In this case, the front cover that opens and closes with respect to the apparatus main body in order to remove the jammed paper and the apparatus main body can be distinguished from each other and the visibility can be improved. That is, it is possible to easily recognize the size of the movable portion with respect to the apparatus main body, and to improve the user's operability and workability and to provide a safe image forming apparatus.

  This is because human beings are generally more conscious in the bright direction, and as a result, the focus of the eyes is shifted in the bright direction as well. In other words, since the consciousness concentrates on bright objects, if the color of the side surface of the image forming apparatus is as bright as the colors of the paper feed tray and the front cover, the consciousness is dispersed throughout the apparatus and the eyes If the focus shifts as a whole and the focus cannot be concentrated on the movable things such as the paper feed tray and the front cover, and the color of the side surface of the image forming apparatus is darker than the colors of the paper feed tray and the front cover, This is because the consciousness is concentrated on the paper feed tray and the front cover, and the focus of the eyes can be shifted and concentrated in the direction of the paper feed tray and the front cover.

  In addition, by making the side surface of the device main body darker, when opening and closing the open / close cover provided on the side surface of the device main body to remove the jammed paper, it was provided on the side surface of the device main body. The distinguishability between the inside of the apparatus main body that is visible when the opening / closing cover is opened and the jammed paper that is visible in that state and the side surface of the apparatus main body is increased, and the visibility is improved. This also has the effect of improving the user operability and workability and providing a safe image forming apparatus.

  This is also the same as above, and people tend to be more conscious in the direction of bright colors, and as a result, the focus of the eyes moves in the direction of bright colors. This is because consciousness concentrates on the color, and at the same time the focus of the eye moves in that direction. Accordingly, the user can concentrate his / her consciousness on the inside of the apparatus main body that is visible when the opening / closing cover provided on the side surface of the apparatus main body is opened and the jammed paper that is visible in that state.
