JP 2000-56703 A

  However, in the display device, the touch panel is integrated on the surface of a display unit such as a liquid crystal screen. Although the touch panel itself has translucency, it is inevitable that the image quality is somewhat deteriorated as compared with the configuration in which the display is displayed only by the display unit.

  Moreover, in the said display apparatus, a display part can only be moved from a storage position to a drawing position, and an enlargement cannot be avoided.

  Furthermore, in spite of a compact configuration, a configuration is desired in which two screens can be switched and displayed one screen at a time, or two screens can be displayed simultaneously.

  Therefore, an object of the present invention is to provide a display device that has a compact configuration and can switch between two screens for display or display two screens simultaneously.

As a means for solving the above problems, the present invention provides:
Display device
A first panel member having a plate shape and one side being a display surface;
A second panel member having substantially the same shape as the first panel member;
The second panel member can be moved to a covering position that covers the display surface of the first panel member and a retreat position that is positioned behind the first panel member so that the display surface of the first panel member is exposed. A position switching member
It is set as the structure provided with.

  With the above configuration, when any one of the two panel members is positioned on the front surface, the remaining other panel member can be positioned behind. That is, although it is a very compact configuration, it is possible to change the positions of both panel members so as to be visible.

  It is preferable that the position switching member can be positioned at a two-screen display position where both the panel members are exposed.

  With this configuration, not only can one panel member be placed at a position where it can be seen, but both panel members can be placed at a position where they can be seen at the same time, and can be arranged freely according to the application. Become.

  The second panel member may be composed of a translucent touch panel member. Note that the touch panel member can be of either pressure-sensitive type or electrostatic type.

  With this configuration, when a touch operation is performed, the second panel member is positioned on the front surface. On the other hand, when emphasizing the visibility of the display unit of the first panel member, the first panel member is positioned on the front surface. it can.

An apparatus main body for supporting the first panel member and the second panel member;
The position switching member is
A support portion formed on the apparatus body;
A link member provided on the support portion so as to be pivotable about a support shaft;
With
Each of the panel members preferably includes a sliding receiving portion that is movable in a direction along the display surface when the sliding portion of the link member slides.

  With this configuration, the front and rear positional relationship can be changed in a stable state while both panel members are supported by the link member.

  The link member is composed of a first link portion and a second link portion that turn around the support shaft, and in a state where at least a part of the two panel members overlap, the sliding portions of the link members are It is preferable that the sliding position of each panel member is shifted in the moving direction.

  With this configuration, the support position of each panel member by the link member can be shifted, and the panel member can be moved in a stable state despite the simple configuration.

The support portion includes a rack that is rotatable about the support shaft,
Each panel member preferably includes a pinion with which the rack meshes in a moving direction along the display surface.

  With this configuration, when the positions of the two panel members are exchanged, the rack is meshed with the pinion, so that a smooth operation can be performed without causing a positional deviation or the like.

  It is preferable to further include a stopping member that stops each panel member at a position where the two panel members overlap each other when the panel member is moved in the moving direction along the display surface.

  With this configuration, it is possible to easily and reliably replace the position of the panel member.

  What is necessary is just to wire-connect between the said 1st panel member and the said 2nd panel member, and between either one of the said panel member and an apparatus main body via the sliding part of a panel member.

  Each panel member and the apparatus main body may be wirelessly connected via a transmission / reception unit provided in each panel member.

  According to the present invention, since the two panel members can be exchanged back and forth, both panel members can be positioned on the front surface despite the compactness, which is convenient.

  Embodiments according to the present invention will be described below with reference to the accompanying drawings.

  1 and 2 show a display device according to the present embodiment. This display device is generally configured by attaching a first panel member 2 and a second panel member 3 to the device body 1.

  The apparatus main body 1 has a rectangular shape in plan view, and a groove portion 4 in which the panel members 2 and 3 are located is formed at the center. As shown in FIG. 3 (a), groove-shaped support portions 5 (one is not shown) are formed at the center portions of both inner side surfaces constituting the groove portion 4, respectively. A support shaft 5a is provided on the support portion 5 so as to be reciprocally movable. A rack 6 and a link member 7 are rotatably attached to the support shaft 5a.

  The rack 6 meshes with a pinion 11 of a link member 7 to be described later, and makes the movement of the link member 7 appropriate with good operability. For this purpose, if necessary, the support state of the rack 6 by the support shaft 5a may be changed to adjust the frictional resistance received when the rack 6 rotates (for example, the rubber supporting portion is supported on the portion supporting the rack 6). It is only necessary to arrange a resistor made of metal.)

  Here, the position switching member is constituted by the rack 6, the link member 7, the pinion 11, and the like.

  The link member 7 includes a first link portion 8 and a second link portion 9. Sliding portions 10 are formed at both ends of each link portion so as to be slidable in the guide groove 12. The first link portion 8 is longer than the second link portion 9, and as a result, the sliding portion 10 is arranged so as to be displaced in a state where it is arranged in the guide groove 12.

  The first panel member 2 is constituted by a transparent touch panel having a rectangular plate shape in plan view. A pinion 11 that engages with the rack 6 from the vicinity of the center toward one end side is formed at the center of both side surfaces of the first panel member 2. The gear portion of the pinion 11 is continuously formed not only in a portion (straight portion 11a) parallel to the front and back surfaces of the first panel member 2, but also in an arc portion (arc portion 11b) on one end side. In addition, a sliding receiving portion, that is, a guide groove 12 in which the sliding portion 10 is slidably disposed is formed inside the gear portion of the pinion 11.

  The second panel member 3 is formed of a liquid crystal display having a substantially same shape as the first panel member 2 in plan view and a large thickness. The liquid crystal display can be used, for example, as a television that displays received video (in this case, an antenna or the like is required separately). The second panel member 3 is also formed with a pinion 11 and a guide groove 12 similar to the first panel member 2.

  The first panel member 2 and the second panel member 3 are both wiredly connected to a control device (CPU, etc.) and a power supply device (both not shown) provided in the apparatus main body 1 via wiring not shown. Has been. What is necessary is just to comprise wiring so that it can penetrate from the support part 5 to an inside, for example. The control device receives a touch operation on the first panel member 2 and performs display control on the second panel member 3. As a method of wired connection, for example, one end of the communication cable is inserted into the sliding portion 10 of the link member 7 located in the guide groove 12 of each panel member 2, 3, and the other end of the communication cable is connected to the apparatus main body. What is necessary is just to connect to the 1 side. Further, the first panel member 2 and the second panel member 3 are connected to each other by a communication cable at each sliding portion 10, and any one of the panel members 2 or 3 and the apparatus main body 1 are connected by a communication cable. Also good. For example, a single optical fiber cable may be used as the communication cable to perform time division data communication. Further, the control device provided in the device main body 1 may be provided in any one of the panel members 2 and 3.

  Further, data transmission / reception between the apparatus main body 1 and the first panel member 2 and the second panel member 3 may be performed wirelessly, and radio waves can be used in addition to light and infrared rays. When radio waves are used, it is only necessary to have a transmission / reception unit for each of them, and they do not need to be arranged to face each other.

  7 and 8 show an example of the layout of the transmission / reception unit when performing optical or infrared communication. Here, transmission / reception units 13 a and 13 b are provided on the inner side surface of the groove portion 4 of the apparatus main body 1 and the side surfaces of the panel members 2 and 3, respectively.

  Next, the operation of the display device having the above configuration will be described.

  When the first panel member 2 is moved from the front surface to the back surface of the second panel member 3, or when the second panel member 3 is moved from the front surface to the back surface of the first panel member 2, the panel member positioned at the front surface is designated. Press and slide to move.

  For example, when the first panel member 2 is located on the front surface, as shown in FIG. 3A, when the first panel member 2 is slid, the rack 6 meshing with the pinion 11 rotates, The two-panel member 3 starts to slide in the direction opposite to the sliding direction of the first panel member 2. During this time, the sliding portion 10 of the link member 7 slides in the guide grooves 12 of the panel members 2 and 3. As described above, the lengths of the first link portion 8 and the second link portion 9 are made different, and the position of the sliding portion 10 located in the guide groove 12 is shifted in the sliding direction. Accordingly, the panel members 2 and 3 are not displaced in a direction different from the sliding direction during the sliding movement, and a smooth movement can be realized.

  When the first panel member 2 is further slid and the overlapping portion with the second panel member 3 is reduced, as shown in FIGS. 2A and 4A, the sliding portion of the link member 7 The position of 10 gradually approaches. The rack 6 that meshes with the pinion 11 of both panel members 2 and 3 extends from the parallel portion 11a to the arc portion 11b. For this reason, the panel members 2 and 3 gradually change the positional relationship between the front side and the back side with the pinion 11 as the center while maintaining a state parallel to the apparatus main body 1. FIG. 4B shows a state in which both panel members 2 and 3 are located on the same plane. In this state, the panel members 2 and 3 are positioned by inserting a spacer into the groove portion 4 of the apparatus main body 1 or projecting a projection (not shown) from the apparatus main body 1 by the stop member. May be. Thus, for example, if both the panel members 2 and 3 are configured by a liquid crystal display, two screens can be displayed in a stable state, which is suitable for use in various applications such as games. . Further, when displaying two screens, a large screen can be displayed if one image or the like is displayed on two screens. For example, when displaying a map, it becomes easy to see by enlarging it. In addition, when used as a display screen for a car navigation system, a wide area map can be displayed on one screen, a route change location, etc. can be enlarged on the other screen, or the display purpose can be changed by 3D (three-dimensional) display, etc. It is also possible to do. Whether or not the display is a two-screen display is detected, for example, by detecting the rotation state of the rack 6 or directly detecting the positions of the panel members 2 and 3 with a sensor (not shown). Each display may be performed when it is determined that the display has started.

  When the first panel member 2 is gradually moved behind the second panel member 3 from the state shown in FIG. 4B as shown in FIGS. 2B and 5A, FIG. As shown in (b), the rack 6 meshing with the pinion 11 gradually reaches the linear portion 11a from the arc portion 11b, and the position of the sliding portion 10 by the link member 7 gradually moves away within the guide groove 12, Due to the reverse operation, as shown in FIG. 6, the second panel member 3 is positioned on the front surface. At this time, since the thickness of the second panel member 3 is larger than that of the first panel member 2, the second panel member 3 is moved to the front by moving the support shaft 5a downward along the support portion 5. Even when positioned on the side, the display surface is set to the same position as when the first panel member 2 is positioned on the front side.

  Thus, since the 1st panel member 2 was comprised with the touch panel and the 2nd panel member 3 was comprised with the liquid crystal display, when touch-operating, the 1st panel member 2 is located in the front, and an image is displayed on a liquid crystal display. Is displayed, the second panel member 3 may be positioned on the front surface. Since the second panel member 3 can be directly viewed by being positioned on the front surface, the visibility can be improved and a clear image can be seen.

  Moreover, if each panel member 2 and 3 is comprised with a liquid crystal display, the front-and-rear position can be replaced or two-screen display can be performed so that either one can be visually recognized.

  In the above-described embodiment, the display panel is a liquid crystal display. However, instead of this, it is also possible to configure the display panel with another thin display such as an organic EL display (organic electroluminescence display).

  Moreover, in the said embodiment, although it did not mention to the positioning in the position (overlapping position) which overlap | superposed each panel member 2 and 3, for example, by making the pinion 11 mesh with the gear part which is not illustrated in the overlapping position. Positioning may be performed by forcibly preventing the rotation of the pinion 11, or the stoppers may be brought into contact with the panel members 2 and 3.

It is a perspective view of the display apparatus which concerns on this embodiment. (A) shows the state which moved the panel member from FIG. 1, (b) is a perspective view which shows the state which changed the front-back position of the panel member. (A) is front sectional drawing of FIG. 1, (b) is front sectional drawing which shows the state which slightly slid the panel member from (a).
