Description

  The present invention relates to a half mirror cover, a cover structure of a housing, and a portable terminal including the same.

  Conventionally, in a foldable mobile phone, when the first casing and the second casing are opened, a main display is provided on the front side of the first casing and a sub-display is provided on the back side. It has been known. Thereby, even when the first casing and the second casing are folded, the time, communication status, charging status, and the like can be confirmed by looking at the sub display (see, for example, Patent Document 1). ). In this cellular phone, a transparent cover that covers the sub display in order to suppress the overall thickness is fitted so as to have the same height as the peripheral edge of the window (opening) of the sub display.

JP 2004-40464 A

  However, if the cover of the display device of Patent Document 1 is intended to give a three-dimensional appearance and improve the appearance, the surface of the cover protrudes beyond the peripheral edge of the opening of the housing and becomes thicker. If an attempt is made to achieve a three-dimensional feeling while keeping the same, there is a problem that a step is generated between the periphery of the opening and the inclined periphery of the cover, and dust tends to accumulate in the step.

  The present invention has been made in view of such points, and the object of the present invention is to provide a three-dimensional effect on the cover periphery without providing a height difference between the opening periphery of the housing and the cover periphery. The purpose is to improve the appearance.

  In order to achieve the above object, in the present invention, a slope is provided on the back side of the edge of the cover that is in contact with the periphery of the opening of the housing, and the back surface of the cover is covered with a half mirror layer.

Specifically, in the first invention, on the premise of the cover structure of the housing that covers the opening of the housing,
The cover structure of the housing includes a cover made of a transparent or translucent material,
The above cover
The height of the surface is the same as the peripheral edge of the opening of the housing,
The back side is covered with a film of a half mirror that reflects light from the outside of the housing and transmits light from the inside of the housing,
A slope is formed on the back side edge located on the back side of the edge contacting the periphery of the opening.

  According to said structure, since the back side of a cover is covered with the film | membrane of a half mirror, unless a light source is made to shine, a cover reflects light. At this time, since a slope is formed on the back side of the edge in contact with the periphery of the opening, the film of the half mirror on the slope reflects light. For this reason, even if it does not provide a slope on the surface side of the cover, when viewed from the surface, it appears to be recessed or bulging from the portion in contact with the peripheral edge of the opening, and a three-dimensional effect is created.

In the second invention, in the first invention,
The said back side edge part is dented to the surface side toward the said opening part periphery.

  According to the above configuration, since the back side of the edge that contacts the periphery of the opening is recessed toward the surface toward the periphery of the opening, the film of the half mirror at the recessed part is reflected and the center of the cover is recessed. Looks like it ’s out. For this reason, even if it does not provide an inclined surface on the surface side of the cover, when viewed from the surface, it appears that a recessed portion having an inclined surface near the periphery of the opening is formed, and a three-dimensional effect is created.

In the third invention, in the first invention,
The said back side edge part inclines in the direction away from the surface toward the said window side periphery.

  According to the above configuration, since the back side of the edge portion in contact with the peripheral edge of the opening is inclined in the direction away from the surface toward the peripheral edge of the window side, the film of the inclined half mirror reflects and the central portion of the cover Seems to be inflated. For this reason, even if it does not provide a slope on the surface side of the cover, when viewed from the surface, it appears that a bulging portion having a slope near the periphery of the opening is formed, and a three-dimensional effect is created.

In a fourth invention, in any one of the first to third inventions,
The light source is a light source of a display device,
In a region excluding the back side edge and the display region at the center of the opening, a light shielding film is formed,
A light guide plate is disposed on the rear surface side of the back side edge, and light from the light source is guided to the light guide plate.

  According to the above configuration, when the display device is not used, a three-dimensional effect near the periphery of the opening is created by the action of the half mirror film, and when the light from the light source is guided to the light guide plate, the edge transmits light. And looks prominent.

In the fifth invention, in the fourth invention,
The light source includes a plurality of LEDs and exhibits an illumination function.

  According to the above configuration, when the LED or the display device is not used, the half mirror film creates a three-dimensional effect near the periphery of the opening, and when the light from the LED is guided to the light guide plate, the edge is light. Illumination is visible and the illuminations stand out.

  In a sixth aspect of the invention, a mobile terminal includes the cover structure for the casing of any one of the first to fifth aspects of the invention.

  According to the above configuration, it is possible to obtain a portable terminal having a good merchandise with a good appearance and a reduced thickness.

In a seventh invention, in the sixth invention,
The case and the operation side case are connected in a foldable manner,
The display device is a sub-display provided on the other surface separately from the main display provided on one surface of the housing.

  According to the above configuration, a compact portable terminal that has a slanted surface but does not have a difference in height from the opening of the sub-display, has a smooth touch, and has a good appearance when folded.

In the eighth invention,
Half mirror cover,
The surface is composed of a flat transparent or translucent material,
The back side is covered with a half-mirror film that reflects light from the front side and transmits light from the back side,
A slope is formed on the back side edge located on the back side of the periphery.

  According to said structure, since the back surface side of a cover is covered with the film | membrane of a half mirror, unless a light source is made to shine from a back surface side, a cover reflects light. Since a slope is formed on the back side of the edge, the film of the half mirror on this slope reflects light. For this reason, even if it does not provide a slope on the surface side of the cover, when viewed from the surface, the peripheral portion appears to be recessed or swelled, creating a three-dimensional effect.

  As described above, according to the present invention, the half mirror film has the same surface height as the peripheral edge of the opening of the housing, reflects light from the outside of the housing, and transmits light from the inside of the back surface. By providing a slope on the back side of the edge that touches the periphery of the opening, the cover periphery has a three-dimensional effect without providing a height difference between the opening periphery of the housing and the cover periphery. Appearance can be improved.

It is a disassembled perspective view of a half mirror cover and a back surface cover. FIG. 6 is a view corresponding to FIG. 4 according to a modification of the present embodiment. FIG. 6 is a view corresponding to FIG. 1 according to a modification of the present embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  2 and 3 show a mobile phone 1 as a mobile terminal provided with a half mirror cover 11 according to a cover structure of a housing according to an embodiment of the present invention. The mobile phone 1 includes a main display 2 on the surface side. A first housing 3 as a closed housing and a second housing 5 as an operation-side housing provided with an operation unit 4 on the surface side are connected to be able to be opened and closed by folding around a hinge portion 6. ing. Note that the first casing 3 is connected to the hinge 6 so that the front and back can be reversed by a vertical axis (not shown) of the hinge 6.

  As shown in FIGS. 4 and 5, the first housing 3 includes a frame 7 into which the main display 2 is fitted on the front surface side, and constitutes a part of the first housing 3 on the back surface side of the frame 7. A back cabinet 8 is attached with a frame-like double-sided tape 9. The frame 7 is formed, for example, by integrally molding an aluminum alloy core material 7a with a synthetic resin. The main display 2 is covered with an acrylic plate 2a from the surface side in a state of being fitted into the frame 7.

  A substantially rectangular opening 8 a is opened at the center of the back cabinet 8. A sub-display 10 as a display device is disposed inside the opening 8a. The sub display 10 is attached to the frame 7 and the surface side thereof is covered with a half mirror cover 11 fitted into the opening 8a.

  The half mirror cover 11 includes a cover main body 11a that is fitted into the opening 8a of the back cabinet 8 and a frame-shaped flange 11b that is provided continuously around the periphery of the cover main body 11a. The cover main body 11a is made of, for example, translucent polycarbonate. The cover main body 11a may be made of other synthetic resin such as an acrylic plate or may be transparent. If it is made of a synthetic resin, there are merits of easy molding and light weight. An adhesive tape 12 made of a double-sided tape or the like is attached to the front surface side of the flange portion 11b and is attached to the back side of the periphery of the opening 8a. As shown in FIG. 4, when the half mirror cover 11 is attached to the opening 8a from the back side of the back cabinet 8, the surface height of the cover body 11a and the surface height of the opening 8a are the same. The gaps between the mating surfaces are kept to a minimum so that dust does not collect.

  As shown in a partially enlarged view in FIG. 1, the entire back surface of the half mirror cover 11 reflects light from outside the back cabinet 8 and transmits light from inside the back cabinet 8. Covered with. The half mirror film 13 is configured such that an extremely thin reflective film is attached by vapor deposition or the like to provide light transmission, and when a certain amount of intense light shines from the back side, the light passes to the front side.

  And the back side edge part 11d located in the back surface side of the edge part 11c which contact | connects the periphery of the opening part 8a in the back surface in which this half mirror film | membrane 13 was provided is dented to the surface side toward the periphery of the opening part 8. . For example, as shown in an enlarged view in FIG. 1, the cross section is recessed in a mountain shape toward the surface side, and the apex of the mountain shape is disposed below the mating surface of the edge portion 11c and the periphery of the opening portion 8a.

  Further, a black light shielding film 14 is formed in a region excluding the back side edge portion 11d and the display region at the center of the opening 8a. For example, the light-shielding film 14 masks a portion of the screen of the sub-display 10 and is applied from above the half mirror film 13 with a roller or plate-like member coated with black paint. Therefore, the light shielding film 14 is not formed on the back side edge portion 11d.

  And as shown in FIG. 4, the light-guide plate 15 is arrange | positioned at the back surface side of the back side edge part 11d. A plurality of LEDs as light sources (not shown) are discretely arranged around the light guide plate 15 so that light from the LEDs is guided. For example, if the LEDs are sequentially turned on when the mobile phone 1 receives an incoming call, the incoming call can be clearly recognized visually with the mobile phone 1 kept closed.

  In the mobile phone 1 configured as described above, since the back surface side of the half mirror cover 11 is covered with the half mirror film 13, the half mirror cover 11 reflects unless the light source of the sub display 10 is illuminated. At this time, since the back side edge portion 11d is recessed toward the surface side toward the periphery of the opening 8a, reflection is performed at the position of the back side edge portion 11d. For this reason, even if the surface of the half mirror cover 11 is not recessed, when viewed from the surface, the edge 11c appears to be recessed as it is away from the opening 8, and as a result, the entire half mirror cover 11 is recessed and recessed. The part appears to be formed, creating a three-dimensional effect.

  On the other hand, when the light from the LED is guided to the light guide plate 15, the back side edge portion 11d transmits the light and looks conspicuous, thereby improving the recognition at the time of incoming call and improving the appearance.

  Therefore, according to the half mirror cover 11 according to the present embodiment, the surface height is the same as the periphery of the opening 8a of the housing, the light from the outside of the back cover 8 is reflected on the back side, and the light from the inside is transmitted. By covering with the half mirror film 13 and providing a slope on the back side edge 11d, the edge 11c is provided with no difference in height between the periphery of the opening 8a of the sub display 10 and the periphery of the half mirror cover 11. Appearance can be improved by giving a three-dimensional effect.

Although the surface appears to be recessed and a recess is formed, there is actually no difference in height from the opening 8a of the sub-display, the touch feels smooth and dust does not accumulate, and the appearance Mobile phone 1 with good merchantability can be obtained -Modification of Embodiment-
6 and 7 show a mobile phone 101 according to a modification of the embodiment of the present invention, which differs from the above embodiment in that the configuration of the back side edge portion 111d of the half mirror cover 111 is different. In addition, the same code | symbol is attached | subjected about the same part as FIGS. 1-5, and the detailed description is abbreviate | omitted.

  That is, the mobile phone 101 in the present modification includes the first casing 3 and the second casing 5 similar to those in the above embodiment, but the back side edge 111d is a surface facing the window side 8a periphery. It is inclined away from the direction. The end point of the slope is located below the mating surface of the periphery of the opening 8a and the edge 111c.

  In this case, when viewed from the surface when light from the light source is not generated, the edge 11c appears to gradually bulge from the mating surface, and as a result, the entire half mirror cover 11 swells and bulges. The part appears to be formed, creating a three-dimensional effect.

  For this reason, even though the thickness of the half mirror cover 111 is not actually increased, the bulge portion appears to be formed on the appearance, but the thickness of the half mirror cover 111 is not actually increased. Since there is no level difference on the surface, the mobile phone 1 that is compact and does not collect dust can be obtained.
