Description

  The present invention relates to an image forming apparatus including a mounting member that can be attached to and detached from a mounted portion.

  In recent years, an image forming apparatus such as a copying machine or a printer can perform image formation based on data transmitted from a mobile terminal such as a smartphone connected by short-range wireless communication such as WiFi. A WiFi substrate for short-range wireless communication is attached to and detached from a mounted portion provided outside a sheet metal housing in which the power supply substrate is accommodated in order to avoid radio wave interference with the power supply substrate and the like. ing.

  As described in Patent Document 1, an antenna surface that receives data of short-range wireless communication may be provided on a cover that covers the upper surface of the image forming apparatus. In such a case, the mounted portion to which the WiFi substrate is attached and detached is often provided inside the cover near the antenna surface.

  In the printer 1 having the above configuration, a procedure for attaching / detaching the connector of the WiFi substrate 50 to the connector 21 of the control substrate 10 will be described with reference to FIGS. 6 is a perspective view showing the WiFi substrate 50 held by the holder 51, FIG. 7 is a perspective view showing the small cover 40 removed from the protective cover 14, and FIG. 8 shows the WiFi substrate 50 positioned with respect to the connector 21. FIG. 9 is a perspective view showing the WiFi substrate 50 attached to the connector 21, FIG. 10 is a perspective view showing the process of attaching the small cover 40, and FIG. 11 is a view when the small cover 40 is attached and when the protective cover 14 is removed. 6 is a plan view for explaining the movement of the small cover 40. FIG.

  First, the WiFi substrate 50 will be described with reference to FIG. A connector (not shown) that can be connected to the connector 21 (see FIG. 3 and the like) is provided on one surface of the WiFi substrate 50. The WiFi substrate 50 is supported by the holder 51. The holder 51 includes a support plate 52 on which the WiFi substrate 50 is supported, hook portions 53 that are provided on both side edges of the support plate 52 and can be elastically deformed, and a handle 54 provided on the back surface of the support plate 52. Yes. Each hook part 53 is elastically deformed outward and the WiFi substrate 50 is superimposed on the support plate 52, and then the elastic deformation of each hook part 53 is released so that the WiFi substrate 50 is supported by the support plate 52 by each hook part 53. Is done.

  First, the screws that fasten the small cover 40 to the protective cover 14 are removed, and the small cover 40 is pulled rightward and removed from the protective cover 14 as shown in FIG. Thereby, the opening part 14d of the protective cover 14 opens.

  Next, as shown in FIG. 8, the handle 54 of the holder 51 is held and attached to the connector 21 from the right side. At this time, the holder 51 is guided to the connector 21 along the upper surface 25 a of the corner plate 25 through the two ribs 26 erected on the upper surface 25 a of the corner plate 25 of the fixed cover 15. By thus being guided horizontally between the two ribs 26, the connector of the WiFi substrate 50 is connected to the connector 21 as shown in FIG. 9. At this time, the connection state can be visually confirmed from the back side of the opening 14d. Further, since a space is formed on the back side of the opening 14d, various operations can be performed in this space.

  After the connector is connected, the opening 14 d of the protective cover 14 is closed with the small cover 40. At this time, the small cover 40 is fitted into the opening 14d from the right side. 10 and 11A, the slit 48 formed in the extension piece 47 of the connection plate 46 of the small cover 40 is erected on the upper surface 25a of the corner plate 25 of the fixed cover 15. The small cover 40 is guided in the left direction along the rib 26 and the upper surface 25 a of the corner plate 25 by engaging with the rib 26 on the back side of the two ribs 26.

  Eventually, the back side edge 40c and the extended piece 40d of the small cover 40 overlap the back side edge 14e and the right side edge 14f of the protective cover 14 respectively (see FIGS. 4 and 5). 11 (A), the extension piece 47 of the connection plate 46 reaches between the rib 26 and the holder 51. Thereafter, the small cover 40 is fastened to the protective cover 14 with screws as described above. Note that the removal of the holder 51 can be performed by a procedure reverse to the above-described procedure.

  Next, procedures for exchanging and maintaining the control board 10 will be described with reference to FIG. FIG. 12 is a perspective view showing a state in which the protective cover 14 is removed.

  First, the two screws that fasten the protective cover 14 to the housing frame are removed. Then, as shown in FIG. 12, the protective cover 14 is pulled out to the rear side and removed. At this time, the small cover 40 fastened to the protective cover 14 is also removed together. However, as shown in FIG. 11B, the extension piece 47 of the small cover 40 includes the rib 26 and the holder 51 of the fixed cover 15. It is pulled out to the back side through the gap between. During the drawing, the connection piece 46 passes above the ribs 26 on the back side. Therefore, the small cover 40 is pulled out without interfering with the ribs 26. Thereafter, the control board 10 is exposed by removing the right fixed cover 17.

  As described above, in the printer 1 of the present invention, the small cover 40 having a small size may be removed from the protective cover 14 in order to attach / detach the WiFi substrate 50. When the small cover 40 is removed, the space between the front side and the side of the connector 21 connected to the WiFi substrate 50 is opened, so that a large work space can be secured. Further, the connection state between the connector of the WiFi substrate 50 and the connector 21 of the control substrate 10 can be visually confirmed. Further, since parts other than the necessary part (such as the control board 10) are not exposed, it is possible to prevent the foreign substance from entering the control board 10 or touching the control board 10 other than the necessary part at the time of attaching / detaching the WiFi substrate 50. .

  On the other hand, when the control board 10 is replaced or maintained, the control board 10 including the WiFi board 50 can be exposed by removing the protective cover 14 together with the small cover 40 and removing the right fixed cover 17. When removing the protective cover 14 together with the small cover 40, the small cover 40 does not interfere with the WiFi substrate 50 and the rib 26, so that the protective cover 14 can be removed smoothly.

  As described above, the WiFi substrate 50 and the control substrate 10 can select the cover to be removed depending on the work content, and thus the usability can be improved.

  Furthermore, since the WiFi substrate 50 is guided by the two ribs 26 and the upper surface 25a of the corner plate 25 and connected to the connector 21, the WiFi substrate 50 can be attached accurately and efficiently. Further, the small cover 40 is also accurately guided to the opening 14 d of the protective cover 14 by these ribs 26. Therefore, the attachment work of the WiFi substrate 50 and the opening / closing work of the opening 14d by the small cover 40 can be efficiently performed.

  In the present embodiment, the case where the WiFi substrate 50 is attached to and detached from the connector 21 that is the attachment part as an attachment component has been described. However, the present invention can also be applied to a USB connector or an option board as an attachment component.

  Furthermore, since the above description of the embodiment of the present invention describes a preferred embodiment of the image forming apparatus according to the present invention, there may be various technically preferable limitations. The technical scope of the present invention is not limited to these embodiments unless specifically described to limit the present invention. That is, the above-described components in the embodiment of the present invention can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible. The description of the embodiment of the present invention described above does not limit the contents of the invention described in the claims.
