[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of an image forming apparatus. In the figure, the image forming apparatus 10 is provided with a main body 12 having a housing 11 in a substantially prismatic column shape that is generally rectangular in plan view. The main body 12 is provided with an image reading unit 13 that reads an original placed on an original placement table 13a located on the upper part of the housing 11, an image forming unit 14 that is located below the image reading unit 13 and forms an image read by the image reading unit 13 on a predetermined sheet, a discharge unit 15 that discharges the sheet on which the image has been formed by the image forming unit 14, and a discharge tray 16 that places the sheet discharged from the discharge unit 15. In this embodiment, an ADF 13b is attached as a part of the image reading unit 13, and the ADF 13b is located on the original placement table 13a.

[0011] The ADF 13b is equipped with a document feed tray 13b1 that is gently inclined from the center toward the upper right, and on the left side is equipped with a mechanism 13b3 that pulls in a document on the document feed tray 13b1, turns it 180 degrees downward, passes it over the upper left surface of the document placement tray 13a, and then discharges it onto a document discharge tray 13b2 below the document feed tray 13b1. The ADF 13b as a whole, including the mechanism 13b3, is colored a light white, but the document feed tray 13b1 and document discharge tray 13b2 are colored a dark charcoal gray. The document is generally white paper, making it easy to distinguish the document on the dark document feed tray 13b1 and document discharge tray 13b2.

[0012] Inside the housing 11 of the main body 12, an internal discharge space 17 is formed, which is located below the image reading unit 13 and opens to the front and left. Furthermore, excluding this internal discharge space 17, the main body 12 has the housing 11 which is continuous in the vertical direction behind and to the right of the internal discharge space 17. The housing 11 as a whole is colored a light white, and the wall surface 17a which forms the internal discharge space 17 is colored a roughly dark dark gray.

[0013] Since the image forming unit 14 is accommodated below and to the right of the internal discharge space 17 within the main body 12, the internal discharge space 17 is formed between the image reading unit 13 and the image forming unit 14 in the main body 12. In this way, the internal discharge space 17 is formed between the image reading unit 13 and the image forming unit 14 in the main body 12, but it does not matter if there are areas to the rear and right between the image reading unit 13 and the image forming unit 14 where the internal discharge space 17 does not exist.

[0014] FIG. 2 is a schematic diagram showing the main configuration of the image forming apparatus. The figure shows a portion below the internal discharge space 17, and the bottom surface of the internal discharge space 17 is formed with a discharge tray 16. The discharge tray 16 is formed to have an inclined surface that slopes upward to the left and downward to the right. As described above, the wall surface 17a that forms the internal discharge space 17 is colored in a dark gray color, and the upper wall surface 17a1 (ceiling portion) of the wall surface 17a is formed horizontally, the right wall surface 17a2 is formed vertically, and the lower wall surface 17a3 (bottom portion) is formed to have an inclined surface that slopes upward to the left and downward to the right. In addition, an operation panel (also called an operation unit) 12a is formed to protrude forward in the right portion of the internal discharge space 17 of the main body 12. The back side of the operation panel 12a is colored in a light white color, and the upper surface, which is the operation portion, is almost entirely covered with a touch panel, and the surrounding bezel portion is colored in a dark black color.

[0015] A paper discharge outlet 15a of the discharge section 15 is formed on the right side of the internal discharge space 17, and the discharge section 15 discharges sheets on which images have been formed in the image forming section 14 located below the internal discharge space 17 to the discharge tray 16 via the paper discharge outlet 15a. The discharge section 15 constitutes part of a transport unit 18 consisting of a transport belt, rollers, etc., and the transport unit 18 transports paper from several stages of paper cassettes 19 arranged at the bottom of the main body 12 to the image forming section 14 and discharges the paper on which an image has been formed. In this way, the transport unit 18 is a mechanism that partially pulls out paper from the paper cassettes 19, transports the paper in the image forming section 14, and discharges the paper in the discharge section 15. In this embodiment, the transport unit 18 is responsible for all of the transport, but it may also be a mechanism that functions separately at each stage.

[0016] In the image forming apparatus 10, paper is transported in the right part inside the main body 12, and in the process, the inkjet type image forming unit 14 forms an image on the paper, and a space is left of the image forming unit 14 below the discharge space 17 inside the main body. The consumables mounting unit 20 of the image forming apparatus 10 is provided in this space. The consumables mounting unit 20 has an ink cartridge 21 accommodated in the upper part, an ink supply unit 22 arranged below it, and a waste liquid box 23 arranged nearby. A predetermined color ink accommodated in the ink cartridge 21 is supplied to the head of the image forming unit 14 via the ink supply unit 22 and used to form an image. In addition, waste liquid discharged during head cleaning performed at a predetermined timing is collected in the waste liquid box 23. The ink cartridge 21 and the ink supply unit 22 are collectively referred to as the ink supply unit, and the waste liquid box 23 is also referred to as the waste liquid storage unit. Incidentally, a control unit 12b is provided within the housing 11, which controls the display and operation input of the operation panel 12a, and controls each unit in response to the operation.

[0017] 1, upper wall surface 17a1, right wall surface 17a2, and lower wall surface 17a3 which form internal discharge space 17 have boundaries which contact the front wall surface of housing 11. The boundaries where right wall surface 17a2 and lower wall surface 17a3 contact the front wall surface of housing 11 are formed so as to draw an arc. Here, the light emitting unit 30 is formed at the front end of the lower wall surface 17a3. Specifically, LEDs that emit white-based light are arranged in a straight line inside, and the upper surface is covered with a blue-based plate to allow diffusion of blue-based light. The light emitting unit 30 is formed in a substantially straight line from the left end of the lower wall surface 17a3, which slopes upward to the left and downward to the right end where the arc begins. In other words, it is formed in a straight line over the length of the front end of the lower wall surface 17a3. The lighting method, which is the light emitting state of the light emitting unit 30, is appropriately controlled by the control unit 12b based on the state of the image forming apparatus 10.

[0018] In this way, the internal discharge space 17 is open on the front side of the image forming device 10, and a light emitting section 30 having a predetermined length is formed along the boundary between the internal discharge space 17 and the housing 11. The light emitting section 30 emits light along a predetermined length along the boundary with the internal discharge space 17 at the front part of the image forming device 10, so that a part of the exterior emits light in a line, and it is easy to see whether it is emitting light or not even from a distant position, and the state of the image forming device 10 can be displayed by this light emitting section 30. In addition, when lit, a bluish light is emitted and diffused. Since a bluish light is emitted at the boundary between the part colored in a dark color and the part colored in a light color, the light emission is accentuated and visibility is improved, so that it can be easily seen even from a distant position.

[0019] As an example of the state of the image forming device 10, the light may indicate that image formation is complete and a sheet has been discharged, or may blink slowly during a series of print jobs, remain lit when the print job is completed, and blink quickly if an error occurs. Of course, these are merely examples, and lighting can be controlled in other ways. In this embodiment, the light-emitting unit 30 is only formed at the boundary between the internal discharge space 17 and the housing 11, but it may also be configured to emit light from the lower part of the operation panel 12a in addition to this. In this case, the operation panel 12a is a plate-shaped operation unit that protrudes forward from the area in front of the image reading unit 13 in the housing 11, and has a sub-light-emitting unit 31 that emits light from the lower part of the operation panel 12a in addition to the light-emitting unit 30. The sub-light-emitting unit 31 is disposed in an easily visible position, so it is easily visible. The image forming apparatus 10 of the embodiment described above is provided with a single-stage paper cassette 19 at the bottom, and is at a height that is easy to use when placed on a table in an office. Of course, the embodiment is not limited to this configuration.

[0020] FIG. 3 is a perspective view of the appearance of an image forming apparatus according to a modified example. Image forming apparatus 110 according to this modified example also comprises a main body 112 having a generally rectangular column-shaped housing 111 that is longer in the height direction than image forming apparatus 10 of the above embodiment, and comprises an image reading unit 113 located at the top, an image forming unit 114 located below image reading unit 113 and forming an image read by image reading unit 113 on a predetermined sheet, a discharge unit 115 that discharges the sheet on which the image has been formed by image forming unit 114, and a discharge tray 116 on which the sheet discharged from discharge unit 115 is placed. Also, four paper cassettes 119 are provided at the lower level, and the height is such that it is easy to work with when installed on a so-called office floor.

[0021] In this embodiment as well, the housing 111 of the main body 112 has an internal discharge space 117 that is located below the image reading unit 113 and opens to the front and left, and the wall surfaces 117a that form the internal discharge space 117 are colored a dark gray color. The wall surfaces 117a that form the internal discharge space 117 include an upper wall surface 117a1 that is formed horizontally, a right wall surface 117a2 that is formed vertically, and a lower wall surface 117a3 that is formed as an inclined surface that slopes upward to the left and downward to the right.

[0022] In the previous embodiment, the light-emitting unit 30 was formed at the front end of the lower wall surface 17a3, but in this embodiment, the light-emitting unit 120 is formed at the boundary between the vertically formed right wall surface 117a2 and the front wall surface of the housing 111. Specifically, the light-emitting unit 120 is formed in a substantially straight line from the upper end of the vertically formed right wall surface 117a2 to the lower end where the arc begins. In other words, the light-emitting unit 120 is formed in a straight line over the length of the front end of the right wall surface 117a2. The light-emitting state of the light-emitting unit 120 is appropriately controlled by a control unit (not shown) based on the state of the image forming apparatus 110.

[0023] The light-emitting unit 120 has LEDs that emit white light arranged in a straight line inside, and the upper surface of the LEDs is covered with a blue plate to enable diffusion of blue light. In this way, the internal discharge space 117 is open on the front side of the image forming device 110, and a light emitting section 120 having a predetermined length is formed along the boundary between the internal discharge space 117 and the housing 111. The light emitting section 120 emits light over a predetermined length along the boundary with the internal discharge space 117 at the front part of the image forming device 10, so that it is easy to visually check whether or not it is emitting light even from a distance, and the state of the image forming device 110 can be displayed by this light emitting section 120. When lit, blue light is emitted and diffused.

[0024] In this embodiment, the light emitting unit 120 is formed long in the vertical direction, and is unlikely to be obscured by obstacles even from a distance. In this embodiment, the light emitting unit 120 is disposed at the front end of the right wall surface 117a2, and in the previous embodiment, the light emitting unit 30 is formed at the front end of the lower wall surface 17a3, but the light emitting unit 130 may be formed at the front ends of both the right wall surface 117a2 and the lower wall surface 117a3. In this case, the light emitting unit 130 may also be disposed in the arc portion where the two are connected. By forming the light emitting unit 130 long, visibility is improved.

[0025] In the image forming devices 10 and 110 of the above-described embodiments, the light-emitting unit 30 and 130 has LEDs that emit white light color arranged in a straight line and the upper surface of the LEDs is covered with a blue plate to diffuse the blue light, but the light-emitting unit is not limited to this configuration. FIG. 4 is a perspective view of the appearance of an image forming apparatus according to a modified example, and FIG. 5 is a partial cross-sectional view of the image forming apparatus.

[0026] In the image forming apparatus 210 of this embodiment, a door 211a that can be opened toward the front side is formed on the lower front surface of the housing 211. The door 211a can be opened and closed by rotating the left end side toward the front side with the right end as the rotation axis. In order to pull out the door 211a when opening and closing it, a generally U-shaped recess 211a1 that opens upward is formed on the upper end of the door 211a as shown in FIG. 5. The recess 211a1 is formed of a front side wall material 211a1a that forms the front surface of the housing 211 with the front side wall surface, a bottom wall material 211a1b that extends toward the rear side from a position slightly lower than the upper end of the front side wall material 211a1a, and a rear side wall material 211a1c that is connected via the bottom wall material 211a1b and extends upward from a position offset toward the rear side of the image forming apparatus 210. The recess 211a1 is called a step portion. At this step, the front side wall material 211a1a is lower than the rear side wall material 211a1c, so the door 211a can be opened by inserting a fingertip and hooking the upper end of the front side wall material 211a1a and pulling it towards oneself.

[0027] A light emitting unit 230 is formed on the back wall surface of the front side wall material 211a1a, i.e., the surface on the side that does not face the front side of the housing 211. The light emitting unit 230 is formed of a linear light emitting element 230a in which an LED 230a1 that emits white-based light has an upper surface covered with a blue-based plate 230a2. The upper end of the door 211a is in contact with the boundary of the lower wall surface 217a3 that forms the internal discharge space 217, and is formed in a generally horizontal straight line. Therefore, the light emitting unit 230 has a shape having a predetermined length along the boundary between the internal discharge space 217 and the door 211a that forms the front surface of the housing 211.

[0028] FIG. 6 is a perspective view of the appearance of an image forming apparatus according to a modified example. In the image forming device 210 shown in Figure 4, the light-emitting unit 230 is arranged at the boundary with the front end of the lower wall surface 217a3 that forms the internal discharge space 217, whereas in the image forming device 310 shown in Figure 6, the light-emitting unit 330 is arranged at the boundary with the front end of the right wall surface 317a2 that forms the internal discharge space 317.

[0029] In the image forming device 210, the light emitting unit 230 illuminates the front side of the back wall material 211a1c from the rear side of the front wall material 211a1a, providing indirect lighting. This provides the effect of being gentle on the eyes even when the light is bright. It goes without saying that the same effect can be obtained in the image forming device 310. In the above embodiments, the light emitting portion is either turned on or off, but the present invention is not limited to this.

[0030] FIG. 7 is a schematic diagram showing a light emitting state of a light emitting section according to a modified example. The light-emitting unit 430 shown in the figure has four light-emitting elements 421-424, and can select between on and off states individually. As shown in a-e of the figure, the basic state is a state where all elements are off, and the light-emitting elements 422-424 can be successively lit from the left light-emitting element 421 to the right. The change in the light-emitting state is implemented by a control unit (not shown). By lighting them one by one in sequence in this manner, it is possible to communicate as if paper is being discharged, and the operation of the image forming apparatus can be recognized even from a distance.

[0031] FIG. 8 is a perspective view of the appearance of an image forming apparatus according to a modified example, and FIG. 9 is a partial cross-sectional view of the same image forming apparatus. In this embodiment, ADF 513b is attached as a part of image reading unit 513, and ADF 513b is disposed on document placement table 513a. ADF 513b is provided with document feed table 513b1 that gently slopes from the center toward the upper right, with mechanism unit 513b3 on the left side, and document discharge tray 513b2 below document feed table 513b1.

[0032] The upper end of ADF 513b is roughly rectangular, but is colored in a light color except for document feed tray 513b1 and document discharge tray 13b2. By removing document feed tray 513b1 and document discharge tray 13b2, the upper surface of ADF 513b is formed into a roughly L-shape. Light-emitting section 530 that emits blue light is formed at the corner of the outer periphery of this L-shape.

[0033] The cross section of the light-emitting unit 530 shown in Fig. 9 is L-shaped, while that shown in Fig. 10 is trapezoidal. The L-shape allows light to be emitted from at least two sides. The trapezoidal shape allows light to be emitted from three sides excluding the bottom. Both light-emitting units 530 irradiate blue light upward and in the peripheral direction. Thus, image reading unit 513 including ADF 513b is disposed at the topmost position of housing 511, and light-emitting unit 530 having a predetermined length is formed on the upper edge of ADF 513b, which is part of image reading unit 513. Since the upper surface of ADF 513b is disposed at the highest position in image forming device 510, it can be seen without being obstructed by obstacles in the office, and the state of image forming device 510 can be easily recognized from a distance depending on the light-emitting state.

[0034] It goes without saying that the present invention is not limited to the above-mentioned embodiment. -Appropriately change and apply the mutually replaceable members and configurations disclosed in the above embodiments. · Appropriately replacing members and configurations that are not disclosed in the above embodiments but are publicly known and can be mutually substituted for the members and configurations disclosed in the above embodiments, and changing the combinations thereof for application. - Substitute members and configurations, etc. that are not disclosed in the above embodiments but that a person skilled in the art could imagine as substitutes for the members and configurations, etc. disclosed in the above embodiments based on publicly known techniques, and change the combinations and apply the present invention. is disclosed as one embodiment of the present invention.
