Description

  The present invention relates to an electronic device that is easy to use for a user and excellent in convenience.

  Conventionally, key input using a keyboard has been the mainstream for input to electronic devices such as personal computers.

  However, in recent years, pen input technology has been developed with a tablet integrated with a display surface, and handwritten character input, image input, handwriting editing, and the like using a pen can be realized. In addition, touch panel technology for inputting information by directly bringing a finger or the like into contact with a liquid crystal display has been developed.

  Here, when performing a key input operation, it is preferable to place the display surface in front of you and place a keyboard in front of it to perform touch typing. In this state, it is the standard posture to perform the key input operation Yes.

  On the other hand, when performing pen input on a tablet, for example, it is preferable to place the tablet surface, which is the display surface, facing upward, and use the pen to write characters on the paper on the desk. It is standard practice to do. The same applies to the touch panel system.

  In addition, a compact storage configuration is also required as an information processing device that is convenient to carry.

  As described above, the information processing apparatus has the display surface of the display unit with respect to the main body so that the display surface of the display unit is folded so as to face the keyboard provided on the main body and the key input operation can be performed. A key input operation state that is opened more than a certain angle, and a pen input operation state in which the display surface of the display unit is placed upwards above the keyboard of the main body so that input by a pen input operation or a touch panel method can be performed.

JP 6-324759 A (published on November 25, 1994) JP 2004-199219 A (published July 15, 2004)

  However, in the first place, the portable electronic device described in Patent Document 1 cannot be arranged with the display surface of the display unit facing upward above the keyboard of the main body.

  Since the information processing apparatus described in Patent Document 2 is disposed above the apparatus main body with the rotated display surface facing directly upward, the user can take an operation posture of looking directly from above when performing pen input. Be strong. In addition, under the influence of the height of the apparatus main body, the user is forced to take an unnatural posture with the elbow bent at the time of pen input. For this reason, it is difficult to say that the information processing apparatus described in Patent Document 2 realizes an information processing apparatus with excellent convenience.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide an electronic device that is easy to use and excellent in convenience for a user.

In order to solve the above problems, an electronic device according to the present invention provides
A flat plate-like main body, a flat plate-like display portion overlapping with the main body, a connecting portion that connects the main body and the display portion, and a main body-side hinge that rotatably connects the connecting portion to the end of the main body And a display unit side hinge that rotatably connects the display unit to the connection unit, and is an electronic device that is installed and used on a flat surface so that the surface of the main body faces upward in the vertical direction. And
When the display unit is rotated about the display unit side hinge, the display surface of the display unit is turned upward, and the connecting unit is rotated to the main unit side about the main unit hinge. The lower end of the display unit is in contact with a plane on which the main body is installed.

  According to the above configuration, the electronic apparatus according to the present invention can turn the display unit around the display unit side hinge so that the display surface of the display unit faces upward. At this time, the display unit is coupled to the display unit side hinge via a coupling unit connected to the main body. Further, when the connecting portion is rotated to the main body side with the main body side hinge as an axis, the lower end of the display portion is in contact with the plane on which the main body is installed.

  That is, the display unit is supported by the display unit side hinge and the plane in the above state, and the position (height) of the display unit supported is lower at the position where the plane supports the display unit. Therefore, the electronic device according to the present invention can realize a state in which the display surface is supported with an inclination (hereinafter also referred to as “second input operation state”).

  Therefore, the user is not required to have an operation posture to look into from the top when checking the display surface. Further, an operation of pulling the main body close to the user so that the user can easily look into the main body from above becomes unnecessary. In addition, when the input operation is possible on the display surface, it is influenced by the height of the main body, and the burden on the user is reduced without being forced into an unnatural posture with the elbow bent during the input operation. can do.

  As described above, in the electronic device according to the present invention, since the display surface is supported by the display unit side hinge and the flat surface with an inclination, it is possible to realize an electronic device that is easy to use for the user and excellent in convenience. .

Furthermore, in the electronic device according to the present invention,
In the main body side hinge, it is preferable that a torque required when the connecting portion is rotated to the main body side is larger than a torque required when the connecting portion is rotated to the opposite side.

  “Rotate the connecting portion toward the main body” means that the display portion rotates toward the second input operation state or the display portion rotates in a direction overlapping the main body.

  Therefore, in the electronic device according to the present invention, by providing the torque difference, the direction opposite to the direction in which the connecting portion is rotated toward the main body, that is, the direction in which the display portion is opened with respect to the main body is provided. Since it is easy to move, when a user puts a hand or a finger between the main body and the display unit or between the display unit and the flat surface, the impact can be reduced.

Furthermore, in the electronic device according to the present invention,
The display surface is a liquid crystal display panel, and it is preferable that the brightness of a pixel in an intermediate gradation when charged is fixed to the display unit in a direction that becomes brighter as it approaches the lower end side from the upper end side.

  When the liquid crystal is charged, light and dark are produced in the pixel to change its direction. At this time, the brightness differs between the top and bottom of the liquid crystal panel depending on the orientation of the liquid crystal. In the case of the arrangement of a normal liquid crystal panel, the brightness changes from white (bright) to black (dark) as the color is reversed as it goes from the upper end side to the lower end side of the display surface. The whiter one displays the image on the display surface more clearly.

  In this regard, in the electronic device according to the present invention, the liquid crystal panel is fixed to the display unit in such a direction that the brightness of the pixels in the intermediate gradation when charged becomes brighter as it approaches the lower end side from the upper end side.

  As a result, since the video on the lower end side of the display surface that is closer to the user is displayed more clearly, an electronic device that is highly convenient for the user can be realized.

Furthermore, in the electronic device according to the present invention,
The connecting portion has a flat plate shape that is narrower than the display portion,
Audio output means for outputting audio from its own device in a region where the lower end of the display unit is in contact with the plane on which the main body is installed and does not overlap with the connecting portion and the display unit on the surface of the main body Preferably, at least one of a voice input unit that inputs voice to the own device and an operation state display unit that displays the operation state of the own device is provided.

  In a state where the lower end of the display unit is in contact with the plane on which the main body is installed, an area that does not overlap the connection part and the display unit on the surface of the main body is open above the area.

  Accordingly, since the display unit and the connection unit do not cover the area, when at least one of the audio output unit, the audio input unit, and the operation state display unit is provided in the area, each unit has The function can be fully exhibited.

Furthermore, in the electronic device according to the present invention,
The display unit is rotated about the display unit side hinge as an axis to bring the back surface of the display unit into contact with the connecting unit, and the connecting unit is rotated to the main unit side about the main unit side hinge. Thus, it is preferable to include a locking portion that locks the main body and the display portion in a state where the main body and the display portion overlap each other.

  By including a locking portion that locks the main body and the display portion, the electronic device according to the present invention is in a state in which the display surface of the display portion is disposed at a position facing the surface of the main body (hereinafter referred to as the main body) , Sometimes referred to as a “storing state”). Therefore, when the user carries the electronic device in the storage state, a situation in which the storage state is unexpectedly released can be avoided.

  The locking portion is realized by, for example, a configuration in which a concave portion provided in the display portion and a convex portion provided in the main body are engaged with each other, or a variety of configurations in which magnets provided in the display surface and the main body are joined together. can do.

  As described above, the electronic device according to the present invention rotates the display unit about the display unit side hinge as an axis so that the display surface of the display unit faces upward, and the main unit side hinge is used as the axis. When the connecting portion is rotated toward the main body, the lower end of the display portion is in contact with the plane on which the main body is installed.

  Therefore, it is possible to realize an input device that is easy to use for the user and excellent in convenience.

Further, in the following description, when referring to the upper side and the lower side, it is assumed that the direction in which gravity is applied is the lower side and the opposite side is the upper side.

[Configuration of Conference Information Terminal Device 1]
FIG. 1 is a diagram for explaining the structure and operation of the conference information terminal device 1. FIG. 1 (a) shows a storage state, FIG. 1 (b) shows a first input operation state, and FIG. FIG. 1C is a diagram showing a state of transition from the first input operation state to the second input operation state, and FIG. 1D is a diagram showing the second input operation state.

  The storage state refers to a state in which the input display surface 3 of the input display unit 2 is arranged at a position facing the key input operation unit 5 of the main body 4. The first input operation state is a state where the input display surface 3 is opened at a certain angle or more with respect to the key input operation unit 5 so that the user can perform a key input operation by the key input operation unit 5 while looking at the input display surface 3. State. The second input operation state refers to a state in which the input display surface 3 is arranged upward so that a data input operation to the input display surface 3 of the input display unit 2 can be performed.

  First, a schematic structure of the conference information terminal device 1 will be described with reference to FIG.

  The conference information terminal device 1 is used in a conference or a meeting, and one or a plurality of conference information terminal devices 1 are connected to a server. Then, using the conference information terminal device 1, the user performs common screen confirmation, screen operation, and the like via the server between the same conference room or remote conference rooms.

  The conference information terminal device 1 includes a flat input display unit (display unit) 2 having an input display surface (display surface) 3 capable of pen input as shown in FIGS. 1B and 1C, for example. A flat plate-like main body 4 having a key input operation section 5 and a connecting section 10 for connecting the input display section 2 to the main body 4. Further, the conference information terminal device 1 is capable of rotating the main body side hinge 7 that rotatably couples one end portion of the connecting portion 10 to the main body 4 and the input display portion 2 to the other end portion of the connecting portion 10. And the display unit side hinge 8 coupled to the main body side hinge 7 and the display unit side hinge 8 (not shown in FIGS. 1B and 1C). Further, the conference information terminal device 1 may include a touch pad 6 in the vicinity of the key input operation unit 5 of the main body 4.

  The input display surface 3 is configured by a flat display such as an LCD (liquid crystal display), a PDP (plasma display panel), or a CRT (cathode-ray tube) display. Further, the input display surface 3 may be capable of pen input with a pen by overlapping a transparent tablet as a data input means on the input display surface 3. Alternatively, the data input means may be capable of finger input using touch panel technology.

  The key input operation unit 5 provided on the surface of the main body 4 is used by the user to input an instruction signal for operating the conference information terminal device 1 and may be considered as a so-called keyboard. Although not shown, the conference information terminal device 1 has, as another operation unit, a remote control for remotely operating the conference information terminal device 1, operation buttons provided on the conference information terminal device 1 itself, or A mouse connected to the conference information terminal device 1 may be included.

  The connecting portion 10 connects the main body 4 and the input display portion 2, and is connected to the main body side hinge 7 at one end and the display portion side hinge 8 at the other end.

  The main body side hinge 7 couples the connecting portion 10 to the end portion of the main body 4 in a rotatable manner. That is, as shown in FIG. 1B, the main body side hinge 7 is opposite to the end of the main body 4 in the Y-axis direction (when viewed from the key input operation section 5, the side on which the touch pad 6 is disposed). The connecting portion 10 is rotatably coupled to the end portion of the main body 4 at the end portion on the side.

  The display-side hinge 8 is for connecting the other end of the connecting portion 10 to the input display portion 2 so as to be rotatable, and is provided on the back side of the input display portion 2. However, the display unit side hinge 8 may be realized by a configuration provided on the side surface of the input display unit 2.

  Here, in the above description, the electronic device according to the present invention is described as being a conference information terminal device. However, the electronic device according to the present invention can be applied to uses other than the conference information terminal device having the same function. In the above description, the input display unit 2 is described as including the input display surface 3. However, the input display unit 2 may include a display surface that does not include an input unit.

  The configuration of the conference information terminal device 1 has been described above. Here, the conference information terminal device 1 further includes a microphone (speech input unit) 20, an LED light (operation state display unit) 21, a rotating piece 22, a non-slip sheet 23, and a locking part 24. It may be realized. Hereinafter, those configurations will be described.

[Other configuration of conference information terminal device 1]
As described above, the conference information terminal device 1 may further include the microphone 20, the LED light 21, the rotary piece 22, the anti-slip sheet 23, and the locking portion 24. Therefore, these configurations will be described with reference to FIGS.

[LED light and microphone]
FIGS. 3A and 3B are diagrams for explaining the mounting positions of the microphone 20 and the LED light 21. FIG. 3A is a first input operation state, and FIG. 3B is a second input operation state. FIG. For convenience of explanation, as shown in FIG. 3A, the X1 axis, the X2 axis, the Y1 axis, and the Y2 axis are temporarily inserted along the four sides of the main body 4.

  As shown in FIG. 3A, the conference information terminal device 1 includes microphones 20 a and 20 b that pick up a user's voice and an LED light 21 for confirming the operating state of the conference information terminal device 1. The confirmation of the operating state means that, for example, the LED light 21 is turned on when the conference information terminal device 1 is powered on, and the LED light 21 is turned off when the conference information terminal device 1 is powered off. .

  As shown in the figure, the microphone 20a is disposed on the upper surface of the main body 4 in the vicinity where the X2 axis and the Y2 axis intersect. On the other hand, the microphone 20b and the LED light 21 are disposed in the vicinity where the X1 axis and the Y2 axis intersect. As a result, in the first input operation state, the microphones 20a and 20b and the LED light 21 can sufficiently exhibit their respective functions without covering the input display unit 2 and the connecting unit 10 upward. The same applies to the second input operation state shown in FIG.

  That is, the conference information terminal device 1 includes the microphones 20a and 20b and the LED light 21 at the above positions, so that the microphones 20a and 20b and the LED light 21 can be controlled in the first input operation state and the second input operation state, respectively. The function which it has can fully be exhibited.

  In addition, the suitable position (area | region) which attaches microphone 20a * 20b and LED light 21 is not restricted to said area | region. That is, as shown in FIG. 3B, the connecting portion 10 has a flat plate shape that is narrower than the input display portion 2, and the lower end of the input display portion 2 comes into contact with the plane on which the main body 4 is installed. In the state (second input operation state), the microphones 20 a and 20 b and the LED light 21 may be attached to a region that does not overlap with the connection part 10 and the input display part 2 on the surface of the main body 4. Thereby, microphone 20a * 20b and LED light 21 avoid the problem that the input display part 2 and the connection part 10 cover up in the 1st input operation state and the 2nd input operation state, and the function which each has is impaired. can do.

  Here, the microphones 20a and 20b and the LED light 21 may be well-known microphones and LED lights, and are not limited to specific types.

  Furthermore, the conference information terminal device 1 may include a speaker (audio output means) for transmitting the speech of the conference participants. The attachment position may be an arbitrary position of the input display unit 2 and the main body 4, but is preferably a region that does not overlap the connection unit 10 and the input display unit 2 on the surface of the main body 4. Thereby, the speaker can avoid the problem that the input display part 2 and the connection part 10 cover up in the 1st input operation state and the 2nd input operation state, and the function is impaired.

[Rotating top and anti-slip sheet]
Next, a configuration in which the conference information terminal device 1 includes the rotary piece 22 and the anti-slip sheet 23 will be described with reference to FIG. FIG. 4 is a view for explaining the rotary piece 22 and the anti-slip sheet 23 attached to the back surface of the main body 4, and is a bottom view of the conference information terminal device 1.

  As shown in the figure, the rotating piece 22 is attached to the back surface of the main body 4 at two locations. The mounting position is not particularly limited, but the area around the X1 axis and the Y2 axis, and the area where the X2 axis and the Y2 axis (corresponding to the X1, X2, Y1, and Y2 axes in FIG. preferable.

  Accordingly, when the user moves the conference information terminal device 1 on the mounting table (plane) 100, the user lifts the front side (Y1 axis side) of the main body 4 as viewed from the user, and then is far from the user. By using the rotation operation of the rotary piece 22 arranged on the side (Y2 axis side), the conference information terminal device 1 can be easily moved.

  However, the position where the rotary piece 22 is provided is not limited to the above position, and may be any position on the back surface of the main body 4. Further, the number of the rotating pieces 22 is not limited to two, and may be one or three or more. The rotating piece 22 may be realized as a piece having any structure realized using a known technique.

  Next, the anti-slip sheet 23 will be described. The non-slip sheet 23 prevents the main body 4 from sliding on the mounting table 100. In the figure, two anti-slip sheets 23 are attached to the back surface of the main body 4 in the X-axis direction of the main body 4. As a case where the non-slip sheet 23 is effective, there may be a case where the main body 4 does not slide on the mounting table 100 when the rotary piece 22 slides down from the mounting table 100.

  The position where the anti-slip sheet 23 is attached is not limited to the above position, and may be any position on the back surface of the main body 4. Further, the number of the non-slip sheets 23 is not limited to two, and may be one or three or more. And the anti-slip | skid sheet | seat 23 may be implement | achieved with the thing of what kind of material implement | achieved using a well-known technique.

[About locking part]
Next, a configuration in which the conference information terminal device 1 includes the locking portions 24 (24a and 24b) will be described with reference to FIG.

  As shown in the figure, the input display unit 2 includes recesses 24 a on both sides (X-axis direction) of the input display surface 3. Further, the main body 4 includes convex portions 24 b on both sides (X-axis direction) of the key input operation unit 5. And the recessed part 24a and the convex part 24b are positioned in the position which mutually engages, when the information terminal device 1 for a meeting is a accommodation state. Thereby, since the recessed part 24a and the convex part 24b engage in the information terminal apparatus 1 for a meeting in the accommodation state, it can latch the input display part 2 and the main body 4. FIG.

  That is, in the conference information terminal device 1, the storage state is brought about by the rotation of the main body side hinge 7 and the display unit side hinge 8. The main body side hinge 7 and the display unit side hinge 8 are easy to operate because of their structure, and easily shift from the housed state to the first input operation state. In other words, it can be said that the storage state is very unstable.

  Therefore, the conference information terminal device 1 includes the locking portion 24 (the concave portion 24a and the convex portion 24b), so that the concave portion 24a and the convex portion 24b can be engaged with each other and the storage state can be maintained more stably. It becomes. In other words, the “play” of the main body side hinge 7 and the display unit side hinge 8 can be eliminated by the locking portion 24, so that the storage state can be reliably maintained even when the user carries the conference information terminal device 1. Can do.

  In addition, the recessed part 24a and the convex part 24b are not restricted to the position shown in figure, You may be positioned in any position as long as it can engage with each other. In the above description, the concave portions 24 a are provided on both sides of the input display surface 3, and the convex portions 24 b are provided on both sides of the key input operation unit 5. However, the locking portion 24 may be realized by a configuration in which the convex portions 24 b are provided on both sides of the input display surface 3 and the convex portion concave portions 24 a are provided on both sides of the key input operation portion 5.

  In the above description, the locking portion 24 is described as including the concave portion 24a and the convex portion 24b. However, the locking portion 24 may be realized by a magnet provided in each of the input display portion 2 and the main body 4. That is, the input display unit 2 includes S pole (N pole) magnets on both sides of the input display surface 3, and the main body 4 includes N pole (S pole) magnets on both sides of the key input operation unit 5. Both magnets are positioned so as to attract each other when the conference information terminal device 1 is in the housed state. As a result, the conference information terminal device 1 can lock the input display unit 2 and the main body 4 because the two magnets attract each other in the housed state.

  Thus, the latching | locking part 24 may be implement | achieved by various structures.

[Configuration of Main Body Side Hinge 7 and Display Unit Side Hinge 8]
Next, the configuration of the main body side hinge 7 will be described with reference to FIGS. 6, 17, and 18.

  6 is a view for explaining the main body side hinge 7, FIG. 6A is a front view of the main body side hinge 7, and FIG. 6B is a side view of the main body side hinge 7. . FIG. 17 is an exploded perspective view of the main body side hinge 7, and FIG. 18 is a cross-sectional view taken along line A-A ′ of FIG.

  As shown in FIG. 17, the main body side hinge 7 includes a bracket 7a, a spring 7b, a shaft 7c, and a stopper 7d. Then, as shown in FIGS. 6A and 6B, the shaft 7c passes through the shaft opening provided in the bracket 7a (see FIG. 18), and further passes through the inside of the spring 7b to the stopper 7d. It is locked.

  In the main body side hinge 7 configured in this way, the bracket 7a has a state holding function, and the spring 7b uses the repulsive force of the spring to urge the input display unit 2 upward (the urging function). ).

  Specifically, the bracket 7a is for holding the input display unit 2 in a state where an angle with respect to the main body 4 is maintained as it is. That is, the bracket 7a can hold the input display unit 2 that is going to move downward due to its own gravity, as it is, using the frictional force between the bracket 7a and the shaft 7c.

  On the other hand, the spring 7b receives the repulsive force of the spring when the input display unit 2 shifts from the stored state to the first input operation state, or when the input display unit 2 shifts from the second input operation state to the first input operation state. Utilizing this function, the input display unit 2 is biased upward (bias function). Thereby, the load demanded by the user when lifting the input display unit 2 from the main body 4 can be reduced.

  Thus, the main body side hinge 7 has both a state holding function and an urging function. A hinge with a torsion spring can be used as the hinge having such a function.

  Next, the configuration of the display unit side hinge 8 will be described with reference to FIG.

  FIG. 7 is a diagram for explaining the details of the display unit side hinge 8. The display unit side hinge 8 includes a display unit side coupling plate 8a coupled to the back surface of the input display unit 2, a coupling unit side coupling plate 8b coupled to the coupling unit 10, and the display unit side coupling plate 8a and the coupling unit side coupling plate. And a shaft portion 8c that engages with 8b. The shaft portion 8c engages the display portion side hinge 8a and the display portion side hinge 8b in a rotatable manner, whereby one end portion of the connecting portion 10 is rotatable with respect to the input display portion 2. Yes.

  Here, the main body side hinge 7 and the display unit side hinge 8 are not limited to the hinges having the structure shown in FIGS. Of course, other types of hinges can be used as long as they have similar functions. Therefore, the main body side hinge 7 and the display unit side hinge 8 can be replaced with other types of hinges according to the structure and shape of the input display unit 2, the main unit 4, or the connecting unit 10.

[Operation of Main Body Side Hinge 7 and Display Unit Side Hinge 8]
Next, operations of the main body side hinge 7 and the display unit side hinge 8 are shown in FIGS. FIGS. 8 to 11 sequentially show the storage state, the first input operation state, the transition from the first input operation state to the second input operation state, and the second input operation state. Each figure (a) shows a top view, each figure (b) shows a perspective view, each figure (c) shows a rear view, and each figure (d) shows a side view.

  The schematic operation of the main body side hinge 7 and the display unit side hinge 8 from the storage state to the second input operation state will be described. The main body side hinge 7 can turn the connecting portion 10 at the end of the main body 4. The display-side hinge 8 is connected to the input display unit 2 so as to be rotatable with respect to the connection unit 10. Then, the input display unit 2 rotates about the display unit side hinge 8 and the input display surface 3 is disposed upward, and the connecting unit 10 rotates about the main unit side hinge 7 to the main unit 4 side. Thus, the lower end of the input display unit 2 comes into contact with the mounting table 100 on which the main body 4 is installed.

  In this way, the information terminal device 1 for a conference shifts from the storage state to the second input operation state or from the second input operation state to the storage state by the rotation of the main body side hinge 7 and the display unit side hinge 8. can do.

  Here, the main body side hinge 7 may have a torque required to rotate the connecting portion 10 to the main body 4 side larger than a torque required to rotate the connecting portion 10 to the opposite side. That is, the input display unit 2 may be realized by a configuration having a direction that is easy to advance and a direction that is difficult to advance according to the moving direction.

  According to the above configuration, by providing a torque difference according to the moving direction, the direction opposite to the direction in which the connecting portion 10 is rotated toward the main body 4, that is, the input display portion 2 is moved with respect to the main body 4. Since it is easy to move in the “open” direction, the impact is reduced when the user puts a hand or a finger between the main body 4 and the input display unit 2 or between the input display unit 2 and the mounting table 100. be able to. In addition, said hinge with a torsion spring can be used as a hinge which has such a function.

[Attachment of contact relaxation rubber to various places]
Next, the contact rubber attached to each part of the conference information terminal device 1 will be described with reference to FIGS.

  FIG. 12 is a view for explaining the attachment position of the contact relaxation rubber 30.

  The contact relaxation rubber 30 is provided at least in the following three locations. The first location is a contact location between the input display unit 2 and the connecting unit 10 and may be attached to at least one of the input display unit 2 or the connecting unit 10. The second part is a contact part between the main body 4 and the connecting part 10, and is attached to at least one of the main body 4 and the connecting part 10, preferably on the connecting part 10 side. The third place is a contact place between the input display unit 2 and the mounting table 100 and is provided on the input display unit 2 side.

  Thereby, in each said location, the impact which the information terminal device 1 for a meeting receives by contact with between members or the mounting base 100 can be relieved, As a result, the risk that the information terminal device 1 for a meeting will be damaged etc. Can be suppressed.

  FIG. 13 is a diagram illustrating the attachment position of the contact relaxation rubber 30 on the bottom surface of the input display unit 2 (the surface of the input display unit 2 rising in the Z-axis direction and positioned on the main body 4 side).

  As shown in the figure, between the first input operation state and the second input operation state, the input display unit 2 supports the back surface by the display unit side hinge 8 coupled to the connecting unit 10 and supports the bottom surface by the main body 4. Has been. Then, the contact relaxation rubber 30 is attached to the bottom surface of the input display unit 2 at a location where it comes into contact with the main body 4.

  Thereby, the impact at the time of the input display part 2 and the main body 4 contacting can be relieved, and the risk that the information terminal device 1 for a meeting will be damaged etc. is reduced.

  Here, FIG. 14 shows an embodiment of the contact relaxation rubber 30 shown in FIG. FIG. 14 is a view for explaining an embodiment of the contact relaxation rubber 30 attached to the bottom surface of the input display unit 2 and in contact with the main body 4.

  As illustrated, the contact relaxation rubber 30 is a triangular prism having a width of 3.3 mm (X-axis direction), a depth of 0.8 mm (Y-axis direction), and a height of 5 mm (Z-axis direction). That is, in the present embodiment, the contact relaxation rubber 30 has a thin depth of 0.8 mm, and therefore does not interfere with the user when the conference information terminal device 1 is used. Although the height is 5 mm, it can be appropriately changed according to the thickness of the main body 4. Similarly, although the width is 3.3 mm, it can be changed as appropriate as the height.

  Here, the material of the contact relaxation rubber 30 described with reference to FIGS. 13 and 14 is not particularly limited, and various rubbers can be used. Further, the shape and size of the contact relaxation rubber 30 are not limited to the shape and size described with reference to FIG. 14, and can be realized in various shapes and sizes.

[Relationship between conference information terminal device 1 and server 200 and internal configuration]
Next, the principal part structure of the conference information terminal device 1 and the relationship with the server 200 will be described with reference to FIG.

  The conference information terminal device 1 is used in a conference or a meeting, and one or a plurality of conference information terminal devices 1 can be connected to the server 200. The user can use the conference information terminal device 1 to check a common screen, operate a screen, etc. via the server 200 between the same conference room or remote conference rooms.

  FIG. 15 is a diagram for explaining the relationship between the conference information terminal device 1 and the server 200 and the internal configuration. As illustrated, a plurality of conference information terminal devices 1 are connected to the server 200. A user of the plurality of conference information terminal devices 1 can check a common screen, perform a screen operation, and the like via the common server 200. Note that the conference information terminal device 1 uses the LAN interface 51 for connection with the server 200. At this time, the connection between the server 200 and the LAN interface 51 may be either wireless or wired.

  Next, the internal configuration of the conference information terminal device 1 will be outlined. The conference information terminal device 1 includes a control unit 50 for controlling each unit of the own device. That is, the control unit 50 controls at least the key input operation unit 5, the input display unit 2, the microphone 20, the LED light 21, the LAN interface 51, and the speaker 52 to exhibit the functions of each unit. In addition, since the control method of each part by the control part 50 may use a well-known technique etc., detailed description here is abbreviate | omitted.

[Operation of Conference Information Terminal Device 1]
Next, the operation of the conference information terminal device 1 will be described with reference to FIG. 1 and FIG. 2 is a side view for explaining the operation of the conference information terminal device 1. FIG. 2 (a) shows the storage state, FIG. 2 (b) shows the first input operation state, and FIG. 2 (c). FIG. 2D is a side view showing a state of transition from the first input operation state to the second input operation state, and FIG. 2D is a side view showing the second input operation state.

  Fig.1 (a) and FIG.2 (a) are figures which show a mode when the information terminal device 1 for a meeting exists in the accommodation state. At this time, the connecting portion 10 is in contact with the back surface of the input display portion 2 (surface opposite to the input display surface 3).

  FIG.1 (b) and FIG.2 (b) are figures which show a mode when the information terminal device 1 for a meeting exists in a 1st input operation state. At this time, the connecting portion 10 is in contact with the back surface of the input display portion 2 as in the housed state.

  In the transition from the storage state to the first input operation state, or the transition from the first input operation state to the storage state, the connecting portion 10 is connected to the main body around the pivot point A via the main body side hinge 7. This is realized by rotating in the “open” direction (the direction in which the storage state is shifted to the first input operation state) or the “closed” direction (the direction in which the transition is made from the first input operation state to the storage state).

  FIGS. 1C and 2C show that the conference information terminal device 1 shifts from the first input operation state to the second input operation state, or from the second input operation state to the first input operation state. It is a figure which shows the mode of time. At this time, the connecting portion 10 is not in contact with the back surface of the input display portion 2, unlike the case of the storage state and the first input operation state. Further, the input display unit 2 has a display unit side hinge 8 coupled to the connecting unit 10 and a rear surface of the input display unit 2, and a bottom surface of the input display unit 2 (that is, the input display unit 2 rising in the Z-axis direction). The bottom surface) is supported.

  The transition between the first input operation state and the second input operation state is such that the connecting portion 10 rotates with respect to the main body 4 around the rotation point A via the main body side hinge 7, and This is realized by rotating with respect to the input display unit 2 around the rotation point B via the display unit side hinge 8.

  Here, as shown in FIG. 2C, the display unit side hinge 8 is provided on the upper side of the input display unit 2 in a state where the input display unit 2 is held in the vertical direction (m, n in the figure). In which m> n). Thereby, the 2nd input state described in below-mentioned Drawing 1 (d) and Drawing 2 (d) is realizable.

  FIG.1 (d) and FIG.2 (d) are figures which show a mode when the information terminal device 1 for a meeting exists in a 2nd input operation state. At this time, as shown in the drawing, the back surface of the input display unit 2 is supported by a display unit side hinge 8 coupled to the connecting unit 10 and a mounting table 100 on which the main body 4 is mounted. Accordingly, the input display unit 2 is in a state in which the input display surface 3 faces upward in the second input operation state.

  In addition, the Z-direction position (height) for supporting the back surface of the input display unit 2 is different between the display unit side hinge 8 and the mounting table 100, and the mounting table 100 has a height for supporting the input display unit 2. Is lower. Therefore, the input display surface 3 is supported with an inclination with respect to the user.

  In FIG. 2D, there is a notch at the front end of the main body 4 (the left front end in FIG. 2, ie, the user's side). The notch has a shape that matches the inclination of the input display unit 2 supported by the display unit side hinge 8 and the mounting table 100. As described above, a notch may be present in the front end portion of the main body 4 (FIG. 2D). In this case, the back surface of the input display portion 2 is in contact with the notch surface of the main body 4. It becomes.

  However, the conference information terminal device 1 does not necessarily require the above-described notch. If the input display unit 2 is supported by the display unit side hinge 8 and the mounting table 100 with an inclination, the conference information terminal device 1 may It is also possible to adopt a configuration in which the notch is not provided.

[Effects obtained by the conference information terminal device 1]
Hereinafter, effects obtained by the conference information terminal device 1 will be described.

  The conference information terminal device 1 includes a flat main body 4, a flat input display portion 2 that overlaps the main body 4, a connecting portion 10 that connects the main body 4 and the input display portion 2, and an end portion of the main body 4. A main body side hinge 7 for connecting the connecting portion 10 so as to be rotatable, and a display portion side hinge 8 for connecting the input display portion 2 so as to be rotatable relative to the connecting portion 10, the surface of the main body 4 facing upward in the vertical direction. It is the information terminal device 1 for a meeting installed and used on the mounting base 100 so that it may become, and the input display part 2 is rotated centering | focusing on the display part side hinge 8, and the input display surface of the input display part 2 is used. When the connecting portion 10 is rotated to the main body 4 side with the main body side hinge 7 as an axis, the lower end of the input display portion 2 comes into contact with the mounting table 100 on which the main body 4 is installed. .

  According to the above configuration, the conference information terminal device 1 can turn the input display unit 2 around the display unit side hinge 8 so that the input display surface 3 of the input display unit 2 faces upward. At this time, the input display unit 2 is coupled to the display unit side hinge 8 via the coupling unit 10 connected to the main body 4. Further, when the connecting portion 10 is rotated toward the main body 4 with the main body side hinge 7 as an axis, the lower end of the input display portion 2 is in contact with the mounting table 100 on which the main body 4 is installed.

  In other words, the input display unit 2 is supported by the display unit side hinge 8 and the mounting table 100 in the above state, and the mounting table 100 supports the input display unit 2 at the supported position (height). The position to do is lower. Accordingly, the conference information terminal device 1 can realize a state where the input display surface 3 is supported with an inclination (second input operation state).

  Therefore, the user is not required to have an operation posture to look into from the top when checking the input display surface 3. In addition, an operation of pulling the main body 4 close to the user so that the user can easily look into the main body 4 from above becomes unnecessary. Furthermore, when an input operation can be performed on the input display surface 3, it is affected by the height of the main body 4, and an unnatural posture with an elbow bent at the time of the input operation is not forced. The burden can be reduced.

  As described above, in the conference information terminal device 1, the input display surface 3 is inclined and supported by the display unit side hinge 8 and the mounting table 100, so that the conference information terminal is easy to use and highly convenient for the user. The device 1 can be realized.

  Further, in the conference information terminal device 1, the main body side hinge 7 has a torque required to rotate the connecting portion 10 to the main body 4 side and a torque required to rotate the connecting portion 10 to the opposite side. It may be a larger configuration.

  “Rotate connecting portion 10 toward main body 4” means that input display portion 2 rotates toward the second input operation state, or input display portion 2 rotates in a direction overlapping main body 4. Means that.

  Therefore, in the conference information terminal device 1, by providing a torque difference, the direction opposite to the direction in which the connecting portion 10 is rotated toward the main body 4, that is, the input display portion 2 is “opened” with respect to the main body 4. Since it is easy to move in the direction, when the user puts a hand or a finger between the main body 4 and the input display unit 2 or between the input display unit 2 and the mounting table 100, the impact can be reduced. Play.

  Furthermore, in the conference information terminal device 1, the input display surface 3 is a liquid crystal display panel, and the input brightness is such that the brightness of the pixels in the intermediate gradation when charged becomes brighter as it approaches the lower end side from the upper end side. The configuration may be fixed to the portion 2.

  When the liquid crystal is charged, light and dark are produced in the pixel to change its direction. At this time, the brightness differs between the top and bottom of the liquid crystal panel depending on the orientation of the liquid crystal. The brightness changes from white (bright) to black (dark) as it goes from the upper end side to the lower end side of the input display surface 3 in the case of a normal liquid crystal panel arrangement. The whiter one displays the image on the input display surface 3 more clearly.

  In this regard, in the conference information terminal device 1, the liquid crystal panel is fixed to the input display unit 2 in such a direction that the brightness of the pixels in the intermediate gradation when charged becomes brighter as it approaches the lower end side from the upper end side. Yes.

  As a result, the video on the lower end side of the input display surface 3, which is closer to the user, is displayed more clearly, making it easy for the user to check the screen and providing the user with the highly convenient conference information terminal device 1. can do.

  This will be described with reference to FIG. 16A and 16B are diagrams for explaining the viewing angle of the liquid crystal panel. FIG. 16A shows a state in which the pixel becomes bright when the voltage is turned off, and FIG. 16C shows that the voltage is turned on. FIG. 16B is a diagram showing a halftone state in which the pixel is dark when it is set. Note that the liquid crystal mainly has optical rotation in the state shown in FIG. 16A, and has optical rotation and birefringence in the state shown in FIG. 16B, and is shown in FIG. 16C. The state is mainly birefringent (substantially zero in the vertical direction).

  As shown in FIGS. 16A to 16C, when the liquid crystal is charged, light and dark are generated in the pixel in order to change the orientation of the liquid crystal. At this time, brightness differs between the top and bottom of the liquid crystal panel depending on the orientation of the liquid crystal. If the arrangement of the liquid crystal panel is normal, the brightness changes from white (bright) to black (dark) as the color is reversed from the top to the bottom. The whiter one can display the image on the input display surface 3 more clearly.

  In this regard, in the conference information terminal device 1, the liquid crystal panel is such that, when charged, the brightness of the pixels in the halftone is white nearer to the user and blacker away from the user in the second input operation state. . That is, in the conference information terminal device 1, the liquid crystal panel is arranged in the opposite direction to the normal liquid crystal panel.

  Thereby, since the image closer to the user can be displayed more clearly on the liquid crystal panel, the highly convenient conference information terminal device 1 can be provided to the user.

  Further, in the conference information terminal device 1, the connecting unit 10 is a flat plate having a narrower width than the input display unit 2, and the lower end of the input display unit 2 abuts on the mounting table 100 on which the main body 4 is installed. In the state, in a region that does not overlap with the connection part 10 and the input display part 2 on the surface of the main body 4, the speaker that outputs the sound from the own apparatus, the microphone 20 that inputs the sound to the own apparatus, and the operation state of the own apparatus are displayed. The LED light 21 may be configured to be provided with at least one of them.

  In a state where the lower end of the input display unit 2 is in contact with the mounting table 100 on which the main body 4 is installed, an area that does not overlap with the connection unit 10 and the input display unit 2 on the surface of the main body 4 is opened above the area. ing.

  Therefore, since the input display part 2 and the connection part 10 material do not cover the area | region, when at least any one of a speaker, the microphone 20, and the LED light 21 is provided in this area | region, a speaker, the microphone 20, And the function which LED light 21 has can be fully exhibited.

  Further, in the conference information terminal device 1, the input display unit 2 is rotated about the display unit side hinge 8 as an axis, the back surface of the input display unit 2 and the connecting unit 10 are brought into contact with each other, and the main body side hinge 7 is disposed. A locking portion 24 is provided for locking the main body 4 and the input display portion 2 in a state where the main body 4 and the input display portion 2 are overlapped by rotating the connecting portion 10 toward the main body 4 as an axis. It may be the composition which is.

  By providing the locking unit 24 that locks the main body 4 and the input display unit 2, the conference information terminal device 1 is positioned so that the input display surface 3 of the input display unit 2 faces the surface of the main body 4. It is possible to more stably maintain the state (stored state) formed by the arrangement. Therefore, when the user carries the conference information terminal device 1 in the stored state, a situation in which the stored state is unexpectedly released can be avoided.

  In addition, the latching | locking part 24 is the structure which mutually engages the recessed part 24a provided in the input display part 2, and the convex part 24b provided in the main body 4, for example, and the magnet provided in the input display surface 3 and the main body 4 mutually. It can be realized by various configurations such as bonding.

The configuration, operation, and effect of the conference information terminal device 1 have been described above. In addition, the shape, dimension, material, and the like of each member of the conference information terminal device 1 are not particularly limited as long as the configuration and effects of the conference information terminal device 1 are realized, and can be appropriately adjusted.
[Other expressions of the present invention]
In order to solve the above problems, an electronic device according to the present invention provides
A main body having a key operation portion on the surface, an input display portion having a data input means on the display surface, a connecting portion for connecting the input display portion to the main body, and one end of the connecting portion being rotated with respect to the main body. A main body-side hinge that is movably coupled; and a display-unit-side hinge that rotatably couples the input display unit to the other end of the coupling unit. The display surface of the input display unit is connected to the main body. The display surface is at a certain angle or more with respect to the key operation unit so that the key operation by the key operation unit can be performed while viewing the display surface and the storage state arranged at a position facing the key operation unit. In an electronic device that can take three states: an open first input operation state and a second input operation state in which the display surface is arranged upward so that the data input operation by the data input means can be performed.
In the second input operation state, the back surface of the input display unit is supported by the display unit side hinge coupled to the connecting unit and a mounting table on which the main body is mounted. Yes.

  According to the above configuration, the electronic device according to the present invention can take three states: a storage state, a first input operation state, and a second input operation state. Among these, the second input operation state is a state in which the display surface of the input display unit is arranged upward so that the data input operation by the data input means can be performed. In addition, in the second input operation state, the back surface of the input display unit is supported by a display unit side hinge coupled to the connecting unit and a mounting table on which the main body is mounted.

  That is, the position (height) for supporting the back surface of the input display unit differs between the display unit side hinge and the mounting table, and the height at which the mounting table supports the input display unit is lower. Therefore, the input display surface is supported with an inclination with respect to the user.

  Accordingly, since the input display surface can face upward in the second input operation state, the user is not required to have an operation posture of looking directly from above during the input operation. Further, an operation of pulling the main body close to the user so that the user can easily look into the main body from above becomes unnecessary. Furthermore, it is possible to reduce the burden on the user without being forced to have an unnatural posture with the elbow bent during an input operation due to the influence of the height of the main body.

  Thus, in the second input operation state, the back surface of the input display unit is supported by the display unit side hinge coupled to the coupling unit and the mounting table on which the main body is mounted, so that it can be used by the user. An electronic device that is easy and excellent in convenience can be realized.

Furthermore, in the electronic device according to the present invention,
In the second input operation state, when the surface area of the main body where the input display section and the connection section overlap with the main body in a top view is the overlapping area,
It is preferable that the main body includes a microphone for picking up a user's voice in a region different from the superimposed region.

In the electronic device according to the present invention,
In the second input operation state, when the surface area of the main body where the input display section and the connection section overlap with the main body in a top view is the overlapping area,
It is preferable that the main body includes an LED light that displays an operation state of the device in a region different from the overlapping region.

  According to the above configuration, in the second input operation state, the input display unit, the connecting unit, and the main body are not superimposed in a region different from the superimposed region in a top view.

  Therefore, by providing a microphone for picking up the user's voice and an LED light for displaying the operation state of the device in a region different from the superimposition region, the input display unit and the connection unit are covered in the second input operation state. The functions of the microphone and the LED light are not impaired by the covering.

  The first input operation state is a state where the display surface is opened at a certain angle or more with respect to the key operation unit so that the key input operation by the key operation unit can be performed while looking at the display surface of the input display unit. Accordingly, there is no overlapping area in the first input operation state. Therefore, if the microphone and the LED light are provided in a region different from the overlapping region in the second input operation state, the microphone and the above-described microphone can be used in both the first input state and the second input operation state. A situation in which the function of the LED light is impaired can be avoided.

Furthermore, in the electronic device according to the present invention,
It is preferable that the main body includes a rotating member used when moving the own apparatus on the mounting table.

  According to the said structure, the said rotation member can be used at the time of the movement of a main body, and a main body can be moved easily. In particular, electronic devices are used for conferences, and are often moved on a desk (on a mounting table) to show a plurality of people drawings, graphs, and the like displayed on an input display surface. In such a case, the burden on the user when moving the device can be reduced by moving the electronic device using the rotating member. At the same time, the apparatus can be moved quickly.

  Note that the number of rotating members may be one or more, and the shape and structure thereof are not particularly limited. Further, for example, when two rotating members are provided on the back of the main body on the side far from the user, the user only has to lift the front side of the main body and move the main body while supporting the two rotating members. Thereby, an electronic device can be moved quickly with a light burden.

Furthermore, in the electronic device according to the present invention,
It is preferable that the main body includes a non-slip member that causes friction between the back surface and the mounting table on the back surface.

  Depending on the back surface of the main body or the material of the mounting table, the electronic device may easily slide on the mounting table. In that case, the user cannot concentrate on the conference or the like in which the user is participating.

  In such a case, in the electronic device according to the invention of the present application, the main body includes a non-slip mechanism that causes friction between the back surface and the mounting table on the back surface. Thereby, the slip of the said back surface of the said main body and the said mounting stand can be reduced, and the user can concentrate on the meeting in which he participates.

  In addition, when the rotation member is provided in the back surface of the main body, the case where a rotation member falls from on a mounting base is also assumed. The above configuration is particularly effective in such a case, and can prevent a situation where the device is momentarily dropped from the mounting table.

Furthermore, in the electronic device according to the present invention,
In the storage state, it is preferable that a locking portion for locking the main body and the input display portion is provided.

  By providing a locking portion that locks the main body and the input display portion, the electronic device according to the present invention has the display surface of the input display portion arranged at a position facing the key operation portion of the main body. The stored state can be more stably held. Therefore, when the user carries the electronic device in the storage state, it is possible to reduce a situation in which the user automatically shifts from the storage state to the first input operation state.

  In addition, as a latching | locking part, various structures, such as the structure which mutually engages the recessed part provided in the input display part, and the convex part provided in the main body, and the magnet provided in the input display surface and the main body, are mutually joined. Can be realized.

Furthermore, in the electronic device according to the present invention,
The display surface is a liquid crystal panel,
In the liquid crystal panel, it is preferable that the brightness of the pixel in the halftone when charged is brighter when it is closer to the user and darker when it is far from the user in the second input operation state.

  When the liquid crystal is charged, light and dark are produced in the pixel to change its direction. At this time, the brightness differs between the top and bottom of the liquid crystal panel depending on the orientation of the liquid crystal. If the arrangement of the liquid crystal panel is normal, the brightness changes from white (bright) to black (dark) as the color is reversed from the top to the bottom. The whiter one displays the image on the display surface more clearly.

  In this regard, in the electronic device according to the present invention, the liquid crystal panel is such that the brightness of the pixels in the halftone when charged is brighter near the user and darker away from the user in the second input operation state. It is comprised so that it may become.

  Thereby, since the image closer to the user can be displayed more clearly on the liquid crystal panel, an electronic device that is highly convenient for the user can be realized.

  The present invention relates to an electronic device that is easy to use for a user and excellent in convenience, and can be suitably used particularly as a conference information terminal device.
