Screen enlargement device and lens support device

Technical field

The present invention relates to a screen enlargement apparatus and a lens support apparatus, and more particularly to an apparatus for enlarging a screen of a small electronic device provided with a display such as a mobile phone or a portable game machine.

Background art

In recent years, various types of small electronic devices such as mobile phones, PDAs, and portable game machines have been provided. These generally have a liquid crystal display, which makes it possible to easily enjoy various contents such as moving pictures such as movies, games, still pictures, etc. anytime and anywhere.

[0003] By the way, although the displays of powerful electronic devices tend to be larger year by year to provide larger images and powerful images, especially in portable type or outdoor type devices, the size of screens becomes larger. There is a natural limit to this, and the screen size can not but be made much smaller compared to stationary equipment.

Therefore, the image may be small and difficult to see. For example, in sports images such as baseball and soccer, players become small like beans and become less realistic, and in movies and role-playing games, they are displayed during subtitles and games in images. Various types of sentences * Characters may be very difficult to read.

On the other hand, as an apparatus for enlarging the display screen of such an electronic device, for example, the inventions described in Japanese Patent Application Laid-Open Nos. 2003-167240 and 2004-56750 have been proposed. Disclosure of the invention

However, these magnifying devices have a relatively simple structure in which the lens is placed on the front of the display, and only the lens is placed on the object to be magnified and the lens is magnified. It is.

[0007] On the other hand, the provision of content to the above-mentioned electronic device may be performed through a communication line. A large volume of moving image data (for example, a long moving image such as a movie) or a game processor In the case of providing a network, although the line capacity and the transmission rate are increased, it is often advantageous to carry out via a storage medium such as a memory card or a storage disk.

[0008] Under such a background, it is possible to simply provide content by storing it in a storage medium, or by simply enlarging the screen of the electronic device with a lens, and by using a more highly useful device 'device. If it can be provided, it can be expected to further invigorate the content industry and thus to contribute to the development of the electronic device and peripheral device industries.

Therefore, an object of the present invention is to enhance the convenience of the device for enlarging the display screen of the electronic device and to improve the utility value.

In order to achieve the above object and solve the problems, a screen enlargement apparatus according to the present invention comprises a case body capable of containing a storage medium, and the case body as a case of an electronic device provided with a display. It is a screen enlarging apparatus having supporting means to support and lens means for enlarging the display screen of the display, wherein the supporting means is engaged with the housing and the case body stands up to the display. A lens capable of supporting the case body around the display, wherein the case body can support the lens means at a distance from the surface of the display in a state of being supported by the support means by the support means It has a support part.

[0011] A lens support device according to the present invention includes a case body capable of containing a storage medium, and a support means for supporting the case body on a case of an electronic device provided with a display. The support means is capable of supporting the case body on the periphery of the display so that the case body can stand against the display by engaging the case, and the case body is It has a lens supporting portion capable of supporting a lens means capable of enlarging a display screen of the display at a distance from the surface of the display in a state of being supported by the supporting means by the supporting means.

The screen enlargement apparatus and the lens support apparatus of the present invention are mounted on a case of a portable electronic device such as a portable telephone or portable game machine, and the display of the electronic device is enlarged by the lens means. Is what makes it possible. The lens means is supported at a distance from the surface of the display by a lens support provided on the case body, and the case body is supported by the support means on the housing of the electronic device. In this case body , Storage media can be stored. Here, the “peripheral portion of the display” includes any portion or position of the periphery of the display, such as the left, right, upper or lower side of the display, for example, and the support means is any of these. Support the case body in part or position.

Therefore, providers of various contents such as movies, images, game software, etc. can store them in a storage medium, store the storage medium in the case body, and provide them to the user. For example, if the content is a movie, movie software is stored in a storage medium such as a memory card, and then stored in the case of the above screen enlargement device or lens support device, and then stored in a store, rental video store, or other store. It can be provided to customers side by side.

On the other hand, a user who has obtained the storage medium takes out the storage medium from the case body, inserts it into the storage medium slot of the electronic device, and mounts the case body on the electronic device by the support means. At the same time, the lens support portion supports the lens means, and the display means greatly enlarged can be enjoyed by the lens means. In addition, when the electronic device is carried around or when the storage medium is not used, the storage medium can be stored in the case body, and the convenience of the screen enlargement apparatus can be improved.

The type and content of data stored in the storage medium are not particularly limited, and may be various data such as image (still image, moving image) data, text data, and the like.

Further, the support means and the case body, and the case body and the lens means may be separable from each other. For example, the support means and the case body can be integrally formed of resin, but the support means and the case body may be separate bodies, and the support means may be detachably attached to the case body. Further, with regard to the relationship between the case body and the lens means, the lens means may be fixed to the case body, but it is also possible to make the lens means detachable. In particular, in the lens support device according to the present invention, an existing lens means (for example, a plate-like Fresnel lens) can be attached to the lens support portion, and the existing lens means is spaced from the surface of the display of the electronic device. It is possible to support the display in an isolated manner, and to enlarge the display screen of the display.

[0017] The lens means may include a plurality of lenses supported at different distances from the display so as to overlap each other with respect to the display, and the lens support may include the plurality of lenses. A plurality of lens supports corresponding to each lens may be included to support the lens.

By using a plurality of lenses in this manner, it is possible to increase the magnification of the display screen. In addition, since the distance from the display to the lens can be reduced as compared with the case of a single lens, it is possible to miniaturize the screen enlargement apparatus at this point.

Further, the case body includes a tray-shaped member on which the storage medium can be placed, and a lid-shaped member capable of covering at least the upper surface side of the tray-shaped member, and the tray-shaped member In some cases, the lid-like member may be slidable relative to the lid-like member, or may be rotatable relative to the lid-like member. Further, in such a case body structure, one of the tray-like member and the lid-like member is provided with the support means, and the other of the tray-like member and the lid-like member is the lens supporting portion. May be provided.

In particular, if the tray-like member and the lid-like member can slide relative to each other as described above, and the supporting means is provided on one of them and the lens supporting portion is provided on the other, the case body The distance between the display and the lens means can be changed using the opening / closing operation (relative sliding between tray and lid), thereby allowing the user to slide relative to each other according to preference. It is possible to adjust the magnification of the screen. It is also advantageous in terms of manufacturing cost because it is not necessary to newly provide a mechanism for moving the lens means up and down (changing the distance from the display).

Further, when a plurality of lenses are used as the lens means as described above, the tray-like member and the lid-like member are configured to be relatively slidable, and the tray-like member and the lid-like member are The support means and at least one lens support of the plurality of lens supports are provided on one side, and at least one of the plurality of lens supports is provided on the other of the tray-like member and the lid-like member. It is desirable to provide one lens support.

It is possible to change the distance between a plurality of lenses by using the relative sliding movement between the tray-like member and the lid-like member, thereby making it possible to more finely adjust the magnification ratio and the viewability of the screen. To make it possible.

Further, among the housings of the electronic device, the surface on the side where the display screen of the display is disposed is the front surface of the housing, and the surface on the opposite side of the side where the display screen of the display is disposed is the rear surface of the housing. age In such a case, the support means projects from the case body, and supports the upper support piece extending to the surface of the case in the supported state of the case body to the case; And a lower support piece extending to the rear surface side of the case in a supported state of the case body, and the case of the electronic device is disposed between the upper support piece and the lower support piece. In some cases, the case body can be supported by the case.

It is. Therefore, for example, even when an incoming call arrives while the mobile phone is attached to the present apparatus and looking at the screen, it is possible to immediately remove the screen enlargement apparatus and talk on the phone with your ear. It is easy to use.

Furthermore, in order to improve the supporting force to the electronic device casing while securing the ease of the intensive attachment and detachment operation, the overhang length of the lower support piece from the case body is made larger than the upper support piece, The upper support piece abuts on a case surface of one side of the display in a state where the case body is supported by the case, and the lower support piece supports the case body to the case. In the state, a protruding portion extending to the rear surface side of the case, a rising portion extending upward so as to wrap the housing from the leading end portion of the protruding portion, and a tip portion extending from the rising portion to the other It can be configured to have a locking portion that abuts the side surface of the housing.

In addition, both the upper support piece and the locking portion of the lower support piece may be formed to extend obliquely downward toward the upper surface of the lower support piece. In this way, even if there are variations in the thickness of the case, the upper support piece and the locking portion extending obliquely downward absorb it flexibly, and the screen magnifier is provided to the case having various thickness dimensions. Can be supported.

It is a feature of this embodiment that the distance between the lens 41 and the display screen 2 is adjustable.

Although the storage medium 5 is a memory card in the present embodiment, it may be another storage medium. In addition, the present embodiment relates to a screen enlargement apparatus for a mobile phone, but other electronic devices (for example, PDA, small game console, DVD player and other image reproduction devices, portable personal computers, car navigation systems, etc.) A screen enlargement apparatus used for various electronic devices provided with a display can be configured in the same manner.

The case body 12 includes a tray 13 on which the memory card 5 can be placed, and a lid 21 covering the surface side of the tray 13 (in particular, see FIG. 3). The case body 12 can be opened and closed by inserting and removing 13 (in other words, by sliding the lid 21 with respect to the tray 13). The tray 13 has a bottom plate 14 having a substantially rectangular planar shape on which the memory card 5 can be placed, elevated portions 15 and 16 provided respectively on one end and the other end of the bottom plate 14, and the bottom plate 14. And a side wall 17 provided on one side. The elevated portions 15 and 16 and the side walls 17 are disposed to surround three sides of the bottom plate 14 (the memory card 5 placed on the bottom plate 14) higher than the bottom plate 14. In order to put the memory card 5 into and out of the case body 12 (tray 13), the tray 13 is pulled out from the lid 21 as shown in FIG. 3, and then the bottom plate 14 on which the side wall 17 is formed The other side force of the bottom plate 14 on the opposite side can also be performed by sliding the memory card 5. In addition, in order to prevent the memory card 5 from slipping out inadvertently, a recess 14 a which can accommodate the memory card 5 may be formed on the surface of the bottom plate 14.

On the outer surface of the side wall 17 formed on one side of the bottom plate 14 as well as on the other side of the bottom plate 14, a rail extending in the insertion and removal direction of the tray 13 with respect to the lid 21 (direction of arrow B in FIG. 3) It forms 18 The rails 18 are parallel to each other, and are respectively fitted in a pair of grooves 24 formed on the inner surface of the side wall 23 (described later) of the lid 21 to slide the tray 13 relative to the lid 21. Combine as much as possible.

On the other hand, in the closed state, the lid 21 has a top plate 22 facing the bottom plate 14 of the tray 13 at a constant distance from the bottom plate 14, a side wall 23 falling from both sides of the top plate 22, and a top plate And an end wall 25 which falls from one end of the body 22. The inner surface of each side wall 23 is fitted with a rail 18 provided on the outer surface of the tray side wall 17 and the other side of the bottom plate 14 to form a groove 24 which can accommodate the rail 18. The lid 21 is supported relative to the tray 13 so as to be slidable relative to the tray 13 by a pair of grooves 24 formed to face each other on the inner surface of the side wall 23 and the rail 18.

Various letters, drawings, images and the like can be arranged on the case body 12 (for example, the surface of the lid 22) by printing, sticking of a label or the like. For example, it is also possible to distribute and provide a title or an image of a movie or game stored in the memory card 5.

The end wall 25 of the lid 21 is formed with a slit 26 extending in the longitudinal direction of the end wall 25 (a direction perpendicular to the insertion / removal direction of the tray 13 or the opening / closing direction of the lid 21). The slit 26 is capable of inserting the plate-like lens 41 and holding it, and is an example of the lens supporting portion for supporting the lens means according to the present invention on the case body 12. Furthermore, as another configuration example of the lid 21, as shown in FIG. 5, a pocket-like lens storage portion 27 capable of storing the plate-like lens 41 (lens means) is provided on the top plate 22 of the lid 21. It is good to form, too. According to such a case body structure, when the screen enlargement device 11 is not used, the slit 26 power lens 41 can be removed and stored in the lens storage portion 27.

In the present embodiment, the support portion 31 for supporting the case body 12 on the case la of the mobile phone 1 is integrally molded with the tray 13 of the case body 12 by a resin. The supporting portion 31 is flexible and has a plate-like shape protruding from the back surface of the tray bottom plate 14 at a constant distance in the longitudinal direction of the tray 13 (in and out directions of the tray 13 with respect to the lid 21). It has an upper arm plate 32 (upper support piece) and a lower arm plate 33 (lower support piece).

The upper arm plate 32 extends obliquely downward from the back surface of the tray 13 (bottom plate 14), and as shown in FIG. 4, the left side (one side portion of the display 2) so as not to get caught on the display screen 2. The tip of L) contacts the case la of the mobile phone. FIG. 4 is a view from the front end side of the mobile phone 1 (the side on which the antenna 3 is provided). In FIG. 4, the symbol D indicates the area where the device play screen 2 is disposed, and the symbol L indicates The left housing area of the display screen 2 is indicated by the symbol R, and the right housing area of the display screen 2 is indicated by the symbol R. The upper arm plate 32 is a housing in the left housing area L of the display 2. The locking portion 36 (described later) of the lower arm plate contacts the surface of the housing la on the surface of the housing 2 on the right side of the display 2.

The lower arm plate 33 projects substantially horizontally from the lower end portion of the back surface of the tray 13 and extends along the back surface of the housing la to the opposite side of the housing la; A rising portion 35 which continuously rises from the tip of the overhanging portion 34 along the side surface of the housing la substantially vertically, and continues to the rising portion 35 from the tip of the rising portion 35 obliquely downward toward the housing la The right side (other side portion R) of the display 2 has a locking portion 36 whose tip end abuts against the casing la.

As described above, the upper arm plate 32 is at one side L of the display 2 and the lower arm plate 33 (locking portion 36) is at the other side R of the display 2 respectively. The case body 12 (screen magnifier 11) can be more reliably secured to the mobile phone by abutting on the la and holding the casing la by the upper and lower arm plates 32, 33 so as to wrap the casing la. The machine 1 can support it. In addition, in order to mount the screen enlargement device 11 on the telephone 1, for example, as shown in FIG. 1, between the upper arm plate 32 and the lower arm plate 33 (upper arm plate 32 and locking portion 36, overhang This can be done by inserting the telephone set 1 from the front end side so as to slide into the part 34).

Furthermore, according to the strong support structure of the present embodiment, the support 31 (case body 12) is slid back and forth (direction of arrow A in FIG. 1) along the longitudinal direction of the housing la. For example, according to the display position of the image in the display, the case body 12 (lens 41 supported by the lens) is powered back and forth to match the image position. There is an advantage that the position can be adjusted. In addition, removal of the screen enlargement device 11 is also easy. Furthermore, both arm plates 32 and 33 have flexibility, and both the upper arm plate 32 and the locking portion 36 of the lower arm plate 33 extend obliquely downward and abut on the housing la. Thus, even if the thickness of the housing 1a varies, the screen enlargement apparatus 11 can be supported by the housing la while absorbing the variation.

FIG. 6 shows another example of the configuration of the support. In this example, the support portion 51 is provided with two flexible arm plates 52 and 53 having a substantially square planar shape. The lower arm plates 53 (lower support pieces) located under the force (lower end portion side of the tray 13) of these arm plates 52, 53 extending parallel to each other and extending from the back surface of the tray 13 The upper arm plate 52 (upper support piece) located on the upper side (center side of the tray 13) has a shorter overhang length than the lower arm plate 53. For this reason, the upper arm plate 52 extends to one side of the display on the surface (screen side surface) of the display unit of the mobile phone, while the lower arm plate 53 is the reverse of the display unit of the mobile phone (opposite to the screen). Extending to the side surface) and extending to the other side of the display.

The lower end of the upper arm plate 52 and the upper end of the lower arm plate 53 have substantially the entire width of each arm plate 52, 53 in the direction orthogonal to the extension direction of each arm plate 52, 53. Protruding ridges (protrusions) 52a, 53a are formed. These ridges 52a, 53a have a semicylindrical shape (having a semicircular cross section), and when the cellular phone is inserted between the two arm plates 52, 53, the ridges provided on the respective arm plates 52, 53 The case 52a, 53a abuts on the casing of the portable telephone to prevent the case body 12 from coming off the casing. In addition, the force, the protruding ridges 52a, 53a are each arm plate 52, 5 Even if it is provided about 2 or more about 3 good re Further, the lower arm plate 53 may extend to the middle of the rear surface of the case which is not necessary to extend to the other side of the case as in this example.

Further, in each of the configuration examples shown in FIGS. 1 and 6, the support portions (upper arm plates 32, 52 and lower arm plates 33, 53) are integrally molded with the case body 12 (tray 13). Although the support portions 31 and 51 are formed separately from the case body 12, the support portions 31 and 51 can be configured to be detachable from the case body 12. Further, each arm plate 32, 33, 52, 53 may have another shape Z structure (for example, a rod-like arm or the like) having a flat plate shape.

The type of the lens 41 is not particularly limited as long as the screen can be enlarged, but in the present embodiment, a resin-made Fresnel lens is used. This is because the manufacturing cost is low and a relatively good magnified image can be obtained. The Fresnel lens 41 is inserted into the slit 26 provided on the case body 12, and is supported so as to be substantially orthogonal to the case body 12 and parallel to the display surface of the portable telephone 1. When the lens housing portion 27 is provided in the case body 12, the Fresnel lens 41 can be stored in the lens housing portion 27 when the apparatus 11 is not used.

The lens 41 may be a lens made of a harder, less flexible or less material lens (eg, made of hard plastic or glass). When the lens is made of a soft reed, a material that is easily damped, the lens 41 supported in a cantilever shape may be slightly squeezed by its own weight, but as described above, depending on the hard material By forming the lens, it is possible to prevent such lens stagnation and obtain a clearer magnified image up to the edge of the screen. In addition, even if the lens itself is formed of a flexible material, if a hard frame material or a support material is provided for the lens, it is possible to similarly prevent the stagnation.

Furthermore, it is acceptable to use a so-called non-reflection lens in which an anti-reflection coating is applied to the lens surface as the lens 41. When using the device 11, the display screen 2 is more easily viewed.

Second Embodiment

The lens that magnifies the screen is not limited to one, and two or more lenses can be used.

The second slit 66 extends in a direction orthogonal to the removal direction of the tray 13 (the opening and closing direction of the lid 21), and is parallel to the first slit 26.

Therefore, the first lens 41 inserted into the first slit 26 and the second lens 71 inserted into the second slit 66 are supported in parallel to the display screen, and both lenses 41 and 71 are used. The screen will be enlarged. Moreover, while the second lens 71 is supported on the tray 13 side, the first lens 41 is supported on the lid 21 side, so the sliding operation between the lid 21 and the tray 13 causes the distance between the two lenses 41 and 71 to move. It is possible to change the size of the screen as needed, so that the user can easily view it.

The lens support portion (first and second slits 26, 66) may be formed into another support structure, for example, another member may be provided by a slit, to support the lenses 41, 71. It is

It will be apparent to those skilled in the art that the present invention can be variously modified within the scope of the claims which are not limited to the embodiment described with reference to the drawings. is there.

For example, the structure of the case body is not particularly limited as long as it can accommodate a storage medium, and various structures other than the above embodiment can be used. If an example is described, although the case body 12 of the said embodiment shall be opened and closed by sliding operation, it is also possible to use the case body which can be opened and closed by rotation operation. That is, a case body 81 shown in FIG. 8 has a lid 82 rotatably attached to one end of a tray 83 provided with a medium storage portion 83a capable of storing a storage medium via a rotation shaft 85. .
