[0009] The "embodiment of the invention" described below is an example of an embodiment. In other words, the invention-specific matters described in the claims are not limited to the specific means and structures shown in the embodiment below. The embodiment of the present invention will be described below with reference to the drawings.

[0010] (First embodiment) 1. Overview of image forming device As shown in Fig. 1, a housing 3 of an image forming apparatus 1 according to this embodiment constitutes the exterior design surface of the image forming apparatus 1. Inside the apparatus main body, i.e., inside the housing 3, an image forming unit 5 that forms an image on a sheet such as paper is housed as shown in Fig. 2.

[0011] The image forming unit 5 according to this embodiment is a monochrome image forming unit among electrophotographic image forming means having a photoconductor 5A, a charger 5B, an exposure unit 5C, a transfer body 5D, and a fixing unit 5E.

[0012] Photoconductor 5A carries a developer image. Charger 5B charges photoconductor 5A. Exposure unit 5C exposes the charged surface of photoconductor 5A to light, thereby forming an electrostatic latent image on the surface of photoconductor 5A. When charged developer is supplied to photoconductor 5A on which the electrostatic latent image has been formed, a developer image is carried on the surface of photoconductor 5A.

[0013] The transfer body 5D is a means for transferring the developer image carried on the photoreceptor 5A to a sheet, and is disposed at a position facing the photoreceptor 5A. The fixing device 5E fixes the developer image transferred to the sheet. The fixing device 5E according to this embodiment is a heating type fixing device that heats the developer to fuse it to the sheet.

[0014] Then, the sheet on which the image formation has been completed is discharged from the discharge outlet 7A and placed on the discharge tray 7. Note that the discharge outlet 7A according to this embodiment opens toward the front side at the upper rear side of the housing 3. The discharge tray 7 is configured with an inclined surface that is inclined so as to become lower as it approaches the discharge outlet 7A.

[0015] Further, below the image forming unit 5 within the housing 3, a paper feed tray 9 having a placement section 9A on which a plurality of sheets can be placed is disposed. This paper feed tray 9 is detachably attached to the device main body, i.e., the housing 3. In this embodiment, the paper feed tray 9 can be attached to and detached from the housing 3 by moving the paper feed tray 9 in the front-rear direction.

[0016] The sheets placed in a stack on the sheet feed tray 9 are fed to the image forming unit 5 in order from the top end side in the stacking direction. 2. Antenna for short-range wireless communication 2, a communication board 11 having an antenna unit 11A for short-range wireless communication is disposed inside the housing 3. In the image forming apparatus 1 according to the present embodiment, short-range wireless communication is performed with a communication device (not shown) such as a portable device via the antenna unit 11A, thereby enabling the following actions, for example.

[0017] That is, (a) operating the image forming apparatus 1 via an operation unit of the communication device, (b) transmitting image data to be formed on a sheet directly from the communication device to the image forming apparatus 1 without going through a computer or the like, and printing the data, or (c) authenticating the owner of the communication device to execute operations that have been permitted in advance for the owner, and prohibiting operations other than those permitted operations, etc.

[0018] Furthermore, on the outer surface of the housing 3, the communication unit 11B corresponding to the antenna unit 11A is provided at a position that allows the communication unit 11B to be seen from above, as shown in FIG. That is, at least above communication unit 11B, there is no component constituting image forming apparatus 1, and there is an open space. Therefore, there is nothing obstructing the user's view from the upper side of communication unit 11B to communication unit 11B, and the user can see communication unit 11B from above.

[0019] Specifically, the communication unit 11B is provided on the upper surface of the front side of the housing 3. An operation unit 13 that is operated by a user is provided on the front side of the housing 3. In other words, the communication unit 11B according to this embodiment is provided on the same side as the operation unit 13 at least in the front-rear direction of the housing 3.

[0020] More specifically, the communication unit 11B according to this embodiment is provided at a position shifted forward with respect to the discharge tray 7 in the front-rear direction of the housing 3. Note that the "front side in the front-rear direction of the housing 3" refers to, for example, the side where the operation unit 13 is provided with respect to the center in the front-rear direction.

[0021] For this reason, when the antenna portion 11A and the charger 5B are projected onto a horizontal plane, the antenna portion 11A projected onto the horizontal plane is misaligned with respect to the charger 5B projected onto the horizontal plane, as shown in Fig. 3. In other words, in this embodiment, the antenna portion 11A projected onto the horizontal plane is located on the opposite side to the fixer 5E projected onto the horizontal plane, across the charger 5B projected onto the horizontal plane.

[0022] 2, communication unit 11B is formed in a horizontal, planar shape. Note that "horizontal" refers to a level that prevents the communication device from slipping off communication unit 11B, i.e., housing 3, when the communication device is placed on communication unit 11B. Also, "planar" refers to a level that prevents the communication device from significantly wobbling when the communication device is placed on communication unit 11B.

[0023] An opening 3A and a front cover 3B are provided on the front surface of the housing 3. The opening 3A connects the inside and outside of the housing 3. The front cover 3B is attached to the housing 3 so as to be displaceable between a position that closes the opening 3A and a position that opens the opening 3A. Note that the front cover 3B according to this embodiment swings and displaces around its lower end side to open and close the opening 3A.

[0024] The antenna portion 11A is disposed above the upper end of the front cover 3B. That is, the antenna portion 11A is located at a position shifted outward from the outer edge of the opening 3A when viewed from the opening direction of the opening 3A (the front-rear direction in this embodiment).

[0025] The opening 3A according to the present embodiment is an access opening for performing operations such as attaching and detaching the process unit 5F and removing a clogged sheet. The process unit 5F is a casing that houses the photoconductor 5A, developer, and the like.

[0026] 3. Features of the image forming apparatus according to this embodiment In this embodiment, the communication unit 11B is provided at a position where the communication unit 11B can be seen from above, so that a communication device such as a smartphone can easily approach or contact the communication unit 11B. Therefore, wireless communication between the antenna unit 11A and the communication device can be satisfactorily established, so that the operability of the image forming apparatus using the communication device can be improved.

[0027] In this embodiment, the antenna portion 11A is disposed so that the antenna portion 11A projected on the horizontal plane is offset from the charger 5B projected on the horizontal plane, so that the distance between the antenna portion 11A and the charger 5B can be made relatively large, thereby preventing the antenna portion 11A from receiving electrical noise from the charger 5B.

[0028] In this embodiment, the antenna portion 11A projected on the horizontal plane is disposed so as to be located on the opposite side of the fixing device 5E projected on the horizontal plane across the charger 5B projected on the horizontal plane, so that the antenna portion 11A can be separated from the fixing device 5E. Therefore, when a heating type fixing device 5E is employed, the antenna portion 11A can be protected from the heat of the fixing device 5E.

[0029] In this embodiment, the communication unit 11B is positioned offset from the discharge tray 7, thereby preventing problems such as a sheet placed on the discharge tray 7 obstructing the communication device from approaching or contacting the communication unit 11B.

[0030] In this embodiment, since the communication unit 11B is located on the upper surface on the front side, the user can easily bring the communication device close to or into contact with the communication unit 11B. In this embodiment, since the communication unit 11B is formed in a horizontal plane, the communication device can be left placed on the communication unit 11B. Therefore, the user does not need to keep holding the communication device, which improves the usability of the image forming apparatus.

[0031] In this embodiment, the antenna unit 11A is disposed above the upper end of the front cover 3B, so that the user can easily bring the communication device close to or into contact with the communication unit 11B regardless of the position of the front cover 3B.

[0032] In other words, if the communication unit 11B were provided on a movable member such as the front cover 3B, the position of the communication unit 11B would be displaced depending on the state of the movable member, making it difficult to bring a communication device close to or into contact with the communication unit 11B.

[0033] Second embodiment The communication unit 11B in the first embodiment was provided at a position shifted forward from the discharge tray 7 in the front-to-back direction of the housing 3, but in this embodiment, the communication unit 11B is provided at a position shifted from the discharge tray 7 in the left-to-right direction of the housing 3, as shown in Figure 4.

[0034] The communication unit 11B according to this embodiment is formed in an inclined surface shape that becomes lower toward the front side. A holder 11C for holding a communication device is provided on the lower end side of the communication unit 11B.

[0035] In addition, the inclined surface constituting the communication unit 11B of the housing 3 may be integrally molded with the top cover 3C that constitutes the housing 3, or molded separately from the top cover 3C and assembled to the top cover 3C, and the configuration is not important.

[0036] Furthermore, the communication unit 11B in this embodiment is formed with an inclined surface that becomes lower toward the front side, so that, for example, in a case where a display unit is provided on the communication device, the user can easily view the display unit while placing the communication device on the communication unit 11B.

[0037] In addition, in this embodiment, a holding portion 11C for holding the communication device is provided on the lower end side of the communication portion 11B, so that the user does not need to hold the communication device continuously. Therefore, the usability of the image forming apparatus can be improved.

[0038] In FIG. 4, communication unit 11B is provided on the rear side, that is, rearward of the center in the front-rear direction, but this embodiment is not limited to this, and communication unit 11B may be provided on the front side.

[0039] In addition, in FIG. 4, the holding portion 11C is formed by a groove extending in the left-right direction, but this embodiment is not limited to this. For example, the holding portion 11C may be formed by a protrusion protruding upward from the top cover 3C, the flat surface of the top cover 3C may be used as the holding portion 11C as it is, or the holding portion 11C may be eliminated.

[0040] Third embodiment In this embodiment, as shown in FIG. 5, the present invention is applied to an image forming apparatus 1 integrated with a reading section 20 that reads image information written on a document.

[0041] That is, the housing 3 according to this embodiment is configured to have a first housing section 31 and a second housing section 32. The first housing section 31 is a housing section in which the image forming section 5 is housed, and corresponds to the housing according to the first embodiment.

[0042] The second housing unit 32 is a housing unit that houses the reading unit 20 and is located above the first housing unit 31, separated by a space 30A. In other words, the reading unit 20 is located above the discharge tray 7, separated by the space 30A.

[0043] Further, an operation panel 32A, which constitutes a part of the second housing unit 32 and has an operation unit 13, is provided at a position of the second housing unit 32 displaced from the reading unit 20. A communication unit 11B is provided on the operation panel 32A.

[0044] Therefore, when the reading unit 20 and the antenna unit 11A are projected onto a horizontal plane, the antenna unit 11A projected onto the horizontal plane is misaligned with respect to the reading unit 20 projected onto the horizontal plane. In this embodiment, the operation panel 32A is shifted forward with respect to the reading unit 20 and is provided at a position that allows the operation panel 32A to be seen from above.

[0045] Therefore, in this embodiment, the user can easily bring the communication device close to or into contact with the communication unit 11B without being hindered by the reading unit 20. Since the communication unit 11B is provided in the second housing unit 32 disposed above the first housing unit 31, the user can easily bring the communication device close to or into contact with the communication unit 11B from above. It is possible.

[0046] 5, the communication unit 11B according to this embodiment is configured to have an inclined surface like that of the second embodiment, but is not provided with a holding portion 11C. However, this embodiment is not limited to this, and the holding portion 11C may be provided on the lower end side of the communication unit 11B, or the communication unit 11B may be formed into a horizontal surface, etc.

[0047] 6, a configuration may be adopted in which a recess 11D is provided that is recessed downward from the upper surface of the operation panel 32A, and the lower end side of the communication unit 11B or the entire communication unit 11B is located at the bottom of the recess 11D. With such a configuration, the communication device can be fitted into the recess 11D, so that the recess 11D can function as the holding unit 11C.

[0048] (Fourth embodiment) In the third embodiment, the communication unit 11B is provided in the second housing part 32, but in this embodiment, the communication unit 11B is provided in a position that can be seen from above in the first housing part 31, as shown in FIG.

[0049] Also in this embodiment, when the reading unit 20 and the antenna unit 11A are projected onto a horizontal plane, the antenna unit 11A projected onto the horizontal plane is misaligned with respect to the reading unit 20 projected onto the horizontal plane.

[0050] Therefore, in this embodiment as well, the user can easily bring the communication device close to or into contact with the communication unit 11B without the reading unit 20 becoming an obstacle. (Other embodiments) The image forming unit in the above-described embodiment was a monochrome electrophotographic type, but the present invention is not limited to this, and the image forming unit may be of any type, such as a color 27 electrophotographic type, or a monochrome or color 27 inkjet type.

[0051] Furthermore, the specific usage form of the short-range wireless communication is not limited to the usage form shown in the above embodiment, and other usage forms are also possible. For example, in a communication device having a display unit such as a liquid crystal panel, the display unit of the communication device may be used as the display unit of the image forming device through short-range wireless communication. By using the communication device as the display unit of the image forming device, a configuration can be realized in which the display unit is omitted from the image forming device, thereby reducing the manufacturing cost of the image forming device.

[0052] Furthermore, the present invention is not limited to the above-described embodiments as long as it conforms to the spirit of the invention described in the claims, and each component of each of the above-described embodiments may be used in combination. [Explanation of symbols]
