It is provided with a backlight unit 5 (see FIGS. 6 and 7) provided inside the operating device 300 so as to be located. Here, the touch panel holder 53 is an example of a support unit, and the backlight unit 5 is an example of a display unit.

The backlight unit 57 is a liquid crystal display, and can display information and operation keys related to the image forming apparatus 100 on the screen. Then, the operation device 300 can accept the user's operation corresponding to the screen displayed on the backlight unit 57 via the touch panel unit 55.

Further, the touch panel unit 55 has a bundle wire 56 connected to a control board (not shown) provided inside the operation device 300. The bundled wire 56 is a connecting wire such as a flexible flat cable.

The touch panel holder 53 has a substantially rectangular opening 77 for making the display surface of the backlight unit 57 visible toward the outside of the operating device 300. As shown in FIG. 3, in the present embodiment, the touch panel unit 55 is attached to the touch panel holder 53 from the outside of the operating device 300, and the backlight unit 57 is located inside the operating device 300.

The display screen of the backlight unit 57 is visible through the substantially rectangular opening 77, and therefore has a substantially rectangular shape.

The touch panel holder 53 has an edge portion that does not form an exterior surface around the opening 77, and a double-sided tape 58 is attached to the edge portion. Then, the touch panel portion 55 is held by the touch panel holder 53 by being attached to the double-sided tape 58.

The double-sided tape 58 is attached to the touch panel holder 53 so as to correspond to the four sides of the substantially rectangular touch panel portion 55. The double-sided tape 58 may be integrally formed of one adhesive member, but the touch panel portion 55 is fixed by a plurality of adhesive members, such as by using a plurality of double-sided tapes divided on each side. You may.

The touch panel holder 53 has a notch portion 75 for inserting the bundled wire 56 into the operation device 300 when the touch panel portion 55 is attached to the touch panel holder 53. The cutout portion 75 has a shape that is recessed outward with respect to the opening 77 at the edge portion of the touch panel holder 53 to which the double-sided tape 58 is attached.

The double-sided tape 58 is attached to the touch panel holder 53 in an area other than the notch portion 75, and the touch panel portion 55 is attached to the opposite surface.

In this way, the touch panel unit 55 is attached so as to be located on the outermost side of the operating device 300. That is, the touch panel unit 55 is provided at a position where the user can perform a touch operation. Here, the touch panel unit 55 is capable of touch operation, flick operation, swipe operation, scroll operation, and the like.

This support frame is also configured to support the control board to which the bundled wire 56 of the touch panel portion 55 is connected. Although not shown in this embodiment, the backlight unit 57 is also provided with a bundle wire for electrically connecting to the control board.

The backlight unit 57 and the control board (not shown) are electrically connected by connecting bundled wires inside the operating device 300. Here, since the bundled wire of the backlight portion 57 is located inside the operating device 300 rather than the touch panel holder 53, it is connected to the control board without forming the notch portion described above.

An exterior cover (not shown) forming an exterior is provided on the side of the operating device 300 opposite to the surface on which the touch panel 55 is provided, and the control board, the support frame, and the like are covered from the back surface of the operating device 300.

As described above, the touch panel holder 53 is formed with a notch portion 75 for inserting the bundled wire 56 of the touch panel portion 55 into the inside. Since the double-sided tape 58 cannot be attached to the notch portion 75, there is a possibility that foreign matter such as dust or dirt may enter the inside of the operation device 300 through the notch portion 75 in the past.

In this way, when foreign matter such as dust invades the inside of the operating device 300, the dust may be present on the surface of the backlight unit 57, resulting in poor visibility of the display screen displayed by the backlight unit. Further, if dust enters the operation device 300, a failure may occur due to poor contact of the bundled wire due to the dust.

Next, the problems in the present embodiment will be described in detail with reference to FIG. FIG. 5 is a cross-sectional view of the operating device 300 not provided with dust countermeasures in the present embodiment, and FIG. 5A is a view of the cross-sectional view taken along the line AA'in FIG. 4 as viewed from the direction of an arrow in the drawing. FIG. 4B is a cross-sectional view taken along the line BB'in FIG. 4 as viewed from the direction of the arrow. (C) is a view of the cross-sectional view taken along the line CC'in FIG. 4 viewed from the direction of the arrow.

As shown in FIG. 5A, at the position where the double-sided tape 58 is attached, the gap between the touch panel holder 53 and the touch panel portion 55 is sealed by the double-sided tape 58, so that dust, dust, etc. Foreign matter 60 is less likely to enter the inside of the operating device 300.

However, as shown in FIGS. 5 (b) and 5 (c), the double-sided tape 58 cannot be attached at the position of the cutout portion 75 through which the bundled wire 56 of the touch panel portion 55 is inserted. Therefore, there is a possibility that foreign matter such as dust or dirt may enter the inside of the operation device 300 through the notch 75 through the minute gap between the touch panel holder 53 and the touch panel 55.

Therefore, in the present embodiment, a sealing member is provided in order to prevent foreign matter such as dust from entering from the outside to the inside of the operating device 300 through the cutout portion 75.

FIG. 6 will explain in detail the configuration of the dust countermeasures in the present embodiment. 6 (a) is an exploded perspective view of the operating device 300, FIG. 6 (b) is a cross-sectional view taken along the line BB'of FIG. 5, and FIG. 6 (c) is FIG. It is the figure which looked at the cross-sectional view of CC'from the direction of an arrow.

In FIG. 6, the region where the notch portion 75 of the touch panel holder 53 is not provided, that is, the region to which the double-sided tape 58 is attached is a support surface that supports the touch panel portion 55, and is shown in FIG. 5 (a). It is almost equal to the configuration. Therefore, as described above, since the gap between the touch panel portion 55 and the touch panel holder 53 is sealed by the double-sided tape 58, it is difficult for foreign matter such as dust and dirt to enter.

As shown in FIG. 6A, the dust countermeasure in the present embodiment has a configuration in which a sealing material 61 made of a sponge or the like is sandwiched between the touch panel portion 55 and the backlight portion 57.

Specifically, as shown in FIGS. 6 (b) and 6 (c), the sealing material 61 is placed on the back surface (sealing) of the touch panel holder 53 by an adhesive layer 61a such as double-sided tape at a position corresponding to the notch portion 75. It is configured to be attached to the material pasting surface) and the back surface of the touch panel portion 55 (the side opposite to the surface to which the user touch-operates). As a result, foreign matter such as dust and dirt is prevented from entering the inside of the operation device 300 through the notch 75 through the gap between the touch panel holder 53 and the touch panel portion 55.

In the present embodiment, the distance S between the touch panel unit 55 and the backlight unit 57 is 3 mm. The sealing material 61 has a thickness of about 5 mm before attachment, and is in a state of being compressed by about 2 mm by the touch panel portion 55 and the backlight portion 57 after the operation device 300 is assembled.

Further, since the sealing material 61 is made of an elastically deformable material such as a sponge, it is possible to fill the gap of the notch portion 75 without buckling the bundled wire 56 of the touch panel portion 55. There is.

As described above, in the operating device 300 of the present embodiment, the gap between the touch panel holder 53 and the touch panel is sealed by the double-sided tape 58 and the sealing material 61, so that dust is collected from the outside to the inside of the operating device 300. It is possible to prevent foreign matter such as dust and dirt from entering. As a result, it is possible to prevent foreign matter such as dust and dirt from entering the region between the touch panel portion 55 and the backlight portion 57 in the thickness direction of the touch panel portion 55 inside the operating device 300. Therefore, it is possible to suppress the deterioration of the visibility of the display screen displayed by the backlight portion due to the presence of foreign matter on the surface of the backlight portion 57 and the occurrence of failure due to poor contact of the bundled wire due to the foreign matter. it can.

<Second embodiment>
Next, the second embodiment will be described with reference to FIG. 7. In this embodiment, the same configurations as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 7A is a perspective view of the operating device 300 according to the second embodiment. FIG. 7B is an enlarged view of the vicinity of the cutout portion 75 in FIG. 7A. FIG. 7 (c) is a cross-sectional view taken along the line BB'in FIG. 7 (a) viewed from the direction of the arrow. In FIG. 7A, the touch panel portion 55 is removed in order to explain the configuration of the cutout portion 75.

As shown in FIG. 7A, the ends 58a and b of the double-sided tape 58 located in the vicinity of the notch 75 are attached to the ends 53a and b of the touch panel holder 53 forming the notch 75. In many cases, it cannot be attached. This is because there are variations in the sticking position of the assembler of the operating device 300 and the like.

Therefore, the distance between the edge portions 53a and b of the touch panel holder 53 and the end portions 58a and b of the double-sided tape 58 may be opened by about 3 mm, respectively. That is, a region where the double-sided tape 58 cannot be attached may occur in the vicinity of the cutout portion 75.

In such a case, foreign matter such as dust or dirt enters the inside of the operating device 300 through a minute gap between the edges 53a and b of the touch panel holder 53 and the ends 58a and b of the double-sided tape 58. There is a risk.

Therefore, in the present embodiment, even if a region where the double-sided tape 58 is not attached occurs near the edges 53a and b of the touch panel holder 53, the cutout portion is cut out in order to suppress the intrusion of foreign matter into the operation device 300. The groove 71 is provided in the vicinity of the 75.

As shown in FIGS. 7A to 7C, in the present embodiment, concave groove portions 71 are formed on the edge portions 53a and b of the touch panel holder 53, respectively. Here, the groove portion 71 is an opening that is recessed in a direction away from the notch 75. In other words, the groove 71 extends in a direction orthogonal to the recessed direction with respect to the opening 77 and the penetrating direction of the opening 77. The groove 71 can collect foreign matter as the opening area becomes larger.

However, if the opening of the groove portion 71 is made too large, the strength of the touch panel holder 53 becomes weak and the end portions 53a and b of the touch panel holder 53 are broken in the vicinity of the groove portion 71.

Therefore, in the present embodiment, the groove portion 71 having a concave shape having a width of about 2 mm and a height of about 3 mm in the plane direction of the touch panel portion 55 is provided so as to suppress a decrease in strength of the touch panel holder 53 and collect foreign matter. One is provided at each of the ends 53a and 53b. In the present embodiment, since the width of the groove 71 is set to be less than half the width of the sticking surface to which the double-sided tape 58 is stuck, it is possible to suppress a decrease in the strength of the touch panel holder 53.

As shown in FIG. 7 (c), dust and dirt pass through the gap between the end portions 58a and b of the double-sided tape 58 and the end portions 53a and b of the touch panel holder 53 from the minute gap between the touch panel holder 53 and the touch panel portion 55. When a foreign matter 60 such as a foreign matter 60 enters, the foreign matter 60 falls into the groove 71 inside the operating device 300.

Then, the foreign matter 60 that has fallen into the groove 71 is collected in the space surrounded by the groove 71 and the sealing material 61. As a result, it is possible to prevent foreign matter such as dust and dirt from entering the region between the touch panel portion 55 and the backlight portion 57 in the thickness direction of the touch panel portion 55 inside the operating device 300.

If the strength decrease of the touch panel holder 53 can be suppressed, the groove portion 71 may be made larger than the above-mentioned size, or a plurality of the groove portions 71 may be provided at the end portions 53a and b of the touch panel holder 53, respectively. ..

According to this configuration, it is possible to more effectively prevent foreign matter such as dust and dirt from being present on the backlight portion 57 inside the operating device 300. Therefore, it is possible to suppress the deterioration of the visibility of the display screen displayed by the backlight portion due to the presence of foreign matter on the surface of the backlight portion 57 and the occurrence of failure due to poor contact of the bundled wire due to the foreign matter. it can.

<Third embodiment>
Next, the third embodiment will be described with reference to FIG. In this embodiment, the same configurations as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 8A is an enlarged cross-sectional view of the vicinity of the cutout portion 75 before the sealing material 61 is attached in the third embodiment. FIG. 8B is an enlarged view of the end portions 53a and b of the touch panel holder 53 in FIG. 8A. FIG. 8 (c) is a cross-sectional view of FIG. 7 (a) in a state where the sealing material 61 is attached. In FIGS. 8A to 8C, the backlight portion 57 is not shown in order to explain the configuration in the vicinity of the cutout portion 75.

In the present embodiment, in order to improve the workability of the characters attached to the sealing material 61, the shapes of the touch panel holder 53 in the vicinity of the ends 53a and 53b are different from those in the above-described embodiment.

More specifically, inclined portions 53c and d are provided on the sticking surface of the sealing material 61, which is the back surface of the touch panel holder 53, so that the thickness gradually decreases toward the notch portion 75. The structure is such that an inclination of 1 mm is formed at a distance of 5 mm in the left-right direction.

In this way, by providing the inclined portions 53c and d at the ends 53a and b of the touch panel holder 53, respectively, when the sealing material 61 is attached to the touch panel holder 53, the inclined portions 53c and d are imitated. The adhesive layer 61a of the sealing material 61 easily adheres to the back surface of the touch panel portion 55. Further, by attaching the adhesive layer 61a following the inclined portions 53c and d, the adhesive layer 61a of the sealing material 61 can be easily attached to the end faces of the end portions 53a and b of the touch panel holder 53.

In the present embodiment, the inclined portions 53c and d are provided on the end portions 53a and b, but if the end portions 53a and b are configured to be thinner than the other portions, a curved surface or another shape is provided. It may be.

FIG. 9 shows a cross-sectional view of the vicinity of the sealing material 61 when the inclined portions 53c and d are not provided. For example, the sealing material 61 has a different force for pressing the sealing material 61 toward the touch panel portion 55 for each sticking operator. Therefore, depending on the operator, the adhesive layer 61a of the sealing material 61 may not adhere to the back surface of the touch panel portion 55, or the area to which the adhesive layer 61a adheres may become small as shown in FIG.

In such a case, the sticking of the sealing material 61 to the back surface of the touch panel holder 53 and the touch panel portion 55 becomes loose, and the space between the touch panel holder 53 and the sealing material 61 or between the touch panel portion 55 and the sealing material 61 becomes loose. There may be a gap between them. If a gap is created, foreign matter such as dust and dirt easily enters the inside of the operating device 300.

On the other hand, in the present embodiment, since the inclined portions 53c and d are provided at the end portions 53a and b of the touch panel holder 53, the area where the sealing material 61 sticks to the touch panel holder 53 can be increased. Therefore, the minute gap between the touch panel holder 53 and the touch panel portion 55 can be more effectively sealed.

Even with this configuration, it is possible to more effectively prevent foreign matter such as dust and dirt from being present on the backlight portion 57 inside the operating device 300. Therefore, it is possible to suppress the deterioration of the visibility of the display screen displayed by the backlight portion due to the presence of foreign matter on the surface of the backlight portion 57 and the occurrence of failure due to poor contact of the bundled wire due to the foreign matter. it can.

<Other Embodiments>
The three embodiments described above may be combined with each other. Further, the sealing material 61 may be provided with a convex shape corresponding to the notch portion 75 in advance. This also enhances the sealing effect of the sealing material 61. Therefore, it is possible to more effectively prevent foreign matter such as dust and dirt from being present on the backlight portion 57 inside the operating device 300.
