Description

  The present invention relates to an image processing apparatus such as a printer, a facsimile machine, a copying machine, a scanner, and a multifunction machine.

  In recent years, image processing apparatuses are increasingly used by being connected to other apparatuses via a network. For this connection, a LAN cable, a parallel cable or the like is used. These communication cables are connected to a printer board, a LAN board, or the like provided in the image processing apparatus.

As described in Japanese Patent Application Laid-Open No. 2003-87465, in order to prevent noise from being radiated to the outside from a printer board or a LAN board, the printer board or the LAN board is stored in a space covered with a shield material. To be done.
JP 2003-87465 A

  However, noise is radiated not only from the printer board and the LAN board, but also from a LAN cable, a parallel cable, or the like. Normally, a LAN cable and a parallel cable are arranged so as to be exposed on the floor or wall of an office with almost no noise countermeasures except that a shield tape for noise emission prevention is wound. When connecting devices with these communication cables, longer communication cables are generally used so that the devices can be reliably connected. Therefore, since an extra portion is formed in the communication cable after connection, the extra portion of the communication cable is generally bundled out of the way and left on the floor.

  However, since the amount of noise radiated is proportional to the length of the communication cable, it is not desirable to use a longer communication cable from the viewpoint of reducing the amount of noise.

  In addition, regulations regarding noise are set in each country, and using a longer communication cable increases the possibility of conflicting with laws and regulations set in each country.

  SUMMARY An advantage of some aspects of the invention is that it provides an image processing apparatus with a low amount of noise radiated from a communication cable to the outside.

  The present invention includes storage means for storing an excess portion of the communication cable connected to the communication means exposed to the outside in the main body. The storage means is made of a metal plate so that noise radiated from the stored communication cable does not come out of the storage means.

  Further, in order to reliably reduce the amount of noise radiated from the communication cable, when the communication cable is not stored in the storage unit, a warning can be notified or the function of the image processing apparatus can be stopped. As described above, the image processing apparatus may be provided with a storage detection unit that detects the storage of the communication cable.

  When the lid of the storage means is open, the shielding effect is reduced. Therefore, when the cover of the storage means is opened and closed, a warning is issued or the function of the image processing apparatus is stopped when the cover is open. In order to do so, an open / close detection means for detecting the open / close of the lid may be provided in the image processing apparatus.

  The amount of noise radiated to the outside from the communication cable can be reduced by storing the communication cable connected to the communication unit exposed to the outside in the storage unit that blocks noise. Therefore, the image processing apparatus can be applied to laws and regulations set in each country.

  Further, by exposing the communication means to the outside, it becomes easy to insert / remove the communication cable to / from the communication means.

(Embodiment 1)
As shown in FIG. 1, the image processing apparatus 100 according to the present invention includes communication means 101 exposed to the outside. The communication unit 101 is, for example, a connector for inserting a communication cable. The external device 110 connected to the image processing apparatus 100 using the communication cable 103 also includes a communication unit 111 similar to the communication unit 101.

  When connecting the image processing apparatus 100 and the external device 110 with a communication cable, the service person first connects both ends of the communication cable 103 to the communication unit 101 and the communication unit 110. If the communication cable 103 is too long, the service person stores the communication cable 103 in the storage means 102 for an extra length.

  As shown in FIG. 1, the storage unit 102 is provided in a lower part of the communication unit 101 of the image processing apparatus 100. The storage means 102 is made of a metal plate, and noise generated in the storage means 102 is blocked by the storage means 102.

  As shown in FIG. 2, two hooks 201 and 202 are provided inside the storage means 102 at the top and bottom. The service person winds the communication cable 103 around the two hooks 201 and 202 up and down by an extra length. By winding the communication cable 103, the length of the communication cable 103 from the storage means 102 to the external device 110 is set to the minimum necessary length that allows the image processing apparatus 100 and the external device 110 to be connected by the communication cable 103. adjust.

  When the communication cable 103 is wound, the service person closes the lid 205 of the storage means 102. As shown in FIG. 1, two notches 203 and 204 are provided above and below the lid 205. When closing the lid 205, the service person closes the lid 205 so that both ends of the wired communication cable 103 pass through the upper and lower cutouts 203 and 204.

  In this way, when the extra portion of the communication cable 103 is accommodated in the accommodating means 102 with respect to the connection between the image processing apparatus 100 and the external device 110, the noise radiated from the extra portion of the communication cable 103 is reduced by the accommodating means. No leakage from 102. Therefore, when the excess portion of the communication cable 103 is stored in the storage means 102, noise radiated to the outside from the communication cable 103 is reduced compared to the case where the excess portion of the communication cable is bundled and left on the floor as in the prior art. Can be reduced.

(Embodiment 2)
Reduction of noise radiated from the communication cable 103 to the outside is not effective unless the communication cable 103 is stored in the storage means 102. A storage detection unit 301 that detects whether the communication cable 103 is stored in the storage unit 102 may be provided in the image processing apparatus 100 so that the image processing apparatus 100 detects the storage of the communication cable 103.

  For example, a load sensor 304 that detects a load applied to the upper hook 201 is provided, and the communication cable 103 is stored in the storage detection unit 301 based on whether the load sensor 304 detects a load of a predetermined weight or more. Let them determine if

  If the storage detection unit 301 determines that the storage is not stored, the image processing apparatus 100 may be configured so that a warning can be notified to a service person or the like.

  For example, when the storage detection unit 301 cannot detect the storage of the communication cable 103, the warning unit 302 displays a warning on a display panel or the like provided in the image processing apparatus 100.

  Further, when the cover 205 of the storage means 102 is open, noise radiated to the outside from the portion of the communication cable stored in the storage means 102 is not blocked. The image processing apparatus 100 may be provided with an open / close detection means 303 for detecting the open / closed state of the lid 205 so that the image processing apparatus 100 detects the opening / closing of the lid 205.

  For example, when the opening / closing detection unit 205 detects that the lid 205 is open, the warning unit 302 displays a warning on the display panel.
