A panel substrate 33 having a panel cover 33b, a transparent plate or LCD sheet 34 attached to the panel cover 31 so as to protect the LCD 33b, and a panel sheet 35 adhered to the surface of the panel cover 31. A conductive panel ground plate 36 is provided between the panel substrate 31 and the panel substrate 33. This panel ground plate 3
Reference numeral 6 is usually made of sheet metal, and has a hole 36a for passing the switch button 32, a hole 36b located above the LCD 33b, and the like. As shown in FIG. 1, the panel grounding plate 36 is attached to the rear surface of the panel cover 31 in close contact, and has a connection portion 36c bent at a right angle at one end (right end in the drawing).

5 and 6, the panel cover 31 has a hole 31b in a portion located above the LCD 33b, and an L around the LCD cover 33b.
A step 31c for attaching the CD sheet 34 is formed. Further, a plurality of holes 3 penetrating therethrough are formed in the step portion 31c.
1d is formed. The hole 36b formed in the panel ground plate 36 has substantially the same size as the hole 31b of the panel cover 31, and therefore, the hole 31d of the panel cover 31
Are located between the LCD sheet 34 and the panel ground plate 36.

As shown in FIGS. 7 and 8, the opening / closing chassis assembly 40 includes an opening / closing chassis 41 having a lower surface partially constituting a document guide, a separator adjuster 42 attached to the opening / closing chassis 41, and a tension spring 43. ,
It has a separator presser 44, a separator adjustment lever 45, a reading pinch roller 16, a reading pinch shaft 47, a reading pinch spring 48, a discharge pinch roller 17, a discharge pinch shaft 50, a discharge pinch spring 51, and the like. Document guide, separator 12 (FIG. 2)
), Read pinch roller 16, discharge pinch roller 17
And the like constitute the upper surface side of the transport path A (see FIG. 2) of the transmission original. The opening / closing chassis assembly 40 further includes an upstream separator ground plate 52 and a downstream reading ground plate 53 made of conductive sheet metal on the back side of the transmission path of the transmission original. 53 is electrically connected by being screwed together with a screw 55. In addition, a ground is further provided to the apparatus main body side by a ground wire 56. Thereby, the transport path of the transmission original is protected from static electricity. The separator ground plate 52 is formed with a connecting portion 52a vertically raised at the upper edge thereof.

In order to assemble the operation panel 30 and the opening / closing chassis assembly 40, as shown in FIG. 9, they are connected by screws 57. At this time, as shown in FIG. And separator ground plate 52
Are connected to each other with screws 58. As a result, the panel ground plate 36 is electrically connected to the separator ground plate 52.

According to the information communication apparatus having the above configuration,
As shown in FIG. 1, a panel ground plate 36 is disposed between the panel cover 31 and a panel substrate 33 below the panel cover 31, and the panel ground plate 36 is connected via a separator ground plate 52, a reading ground plate 53, and a ground wire 56. Grounded on the main unit side. Thereby, the static electricity 60 is applied to the panel cover 31.
Is dropped, the static electricity only flows from the panel ground plate 36 as shown by the arrow, and does not affect the panel substrate 33. Thus, the panel cover 31 and the panel substrate 33
Can be reduced, and the size of the device can be reduced. Also, as shown in FIG.
In the vicinity of 33b, the step portion 31 of the panel cover 31 located between the LCD sheet 34 and the panel ground plate 36 is provided.
Since the hole 31d penetrates through the hole 31c, the static electricity 61 dropped in the vicinity is absorbed by the panel ground plate 36 through the hole 31d, and the LCD 33b is protected.

Further, at the time of assembling, the panel grounding plate 36 can be grounded by connecting the connecting portion 36c of the panel grounding plate 36 and the connecting portion 52a of the separator grounding plate 52 with a screw 58, so that assembly is simple. is there.

[0021]

As is apparent from the above description, the present invention
The panel ground plate to the back of the panel cover
Pass it well away from the panel board while attaching
Since the static electricity is released, the effect of the static electricity can be prevented and the size of the apparatus can be reduced.

[0022]

Also, the first ground plate is attached to the rear surface of the panel cover substantially in close contact, and the second ground plate is mounted close to the upper surface of the opening / closing chassis, and one end is connected to the first ground plate. The first ground and the second ground cover the inner space of the opening / closing section formed by the panel cover and the opening / closing chassis along the inner periphery thereof, so that the inner space of the opening / closing section is separated from the panel board by a maximum. Since the static electricity escapes at a limited distance, even if the internal space of the opening / closing section is reduced, the effect of the static electricity on the panel substrate and the conveyance path of the document can be sufficiently prevented, and the apparatus can be downsized. it can. Moreover, when assembling,
By connecting the first ground plate to the second ground plate, grounding can be achieved, and the assembly can be easily performed. Further, when the panel substrate has a display unit and the panel cover holds a transparent plate protecting the display unit, a hole penetrating through a portion of the panel cover located between the transparent plate and the panel ground plate. Is formed, the static electricity dropped on the panel cover is released to the panel grounding plate through the hole, and the display portion can be protected.
