Description

  The present invention relates to a foldable portable electronic device that is portable and can be opened and closed via a hinge portion.

  Currently, a large number of portable electronic devices such as portable information terminals such as mobile phones and PDAs, electronic dictionaries and notebook personal computers are provided. Among this kind of portable electronic devices, there are ones that are used while being held in the hand and those that are used while being placed on a flat surface such as a desk. Even if it is a portable electronic device used in any state, a foldable type is known as one of the measures for achieving compactness.

  As shown in FIG. 22, such a foldable portable electronic device generally has a structure in which one case 100 and the other case 101 are connected to each other through a hinge portion 102 so as to be opened and closed by about 180 degrees. It is. In this case, the hinge part 102 is often provided in a state of protruding outward from both cases 100 and 101 when the other case 101 is closed. This is to make one case 100 and the other case 101 flat when the portable electronic device is opened.

However, portable electronic devices of the type described above have a structure that is difficult to reduce in size and difficult to further reduce in size. That is, when the portable electronic device is closed, the hinge portion 102 protrudes outward from both cases 100 and 101. Therefore, even if the lateral width L1 of the case portion is designed to be short, the protrusion of the hinge portion 102 Under the influence, the entire width L2 is inevitably increased. Therefore, it has been difficult to reduce the size.
In particular, since the portable electronic device is carried in a bag or a pocket with the portable electronic device closed, it becomes an obstacle when the size is large, it is difficult to hold, and the user is uncomfortable.

Therefore, there is known a hinge structure in which the hinge portion is disposed inside the case to prevent the hinge portion from protruding outward. This hinge structure is used in various products, and is used in, for example, mobile phones (see Patent Document 1), containers for storing cosmetics and cosmetics (see Patent Document 2), and the like.
By adopting this hinge structure, the protrusion of the hinge portion can be eliminated, so that the width of the entire product can be suppressed, leading to downsizing.
JP 2007-192284 A JP 2005-192709 A

  However, when the hinge structure in which the hinge portion is arranged inside the case is adopted, as shown in FIG. 23, when the case 100 and 101 are opened, when the opening angle exceeds a certain angle, the other side The case 101 gets under the one case 100. For this reason, the lower surfaces of both cases 100 and 101 are not flat, and a step is formed.

  In this regard, in the case of a mobile phone, since it is used by holding it in hand, it can be used without any problems even if both cases have steps. On the other hand, in the case of a container for storing cosmetics and cosmetics, it is inclined on the desk due to the step difference between the two cases at the time of use.

However, when the hinge structure is used in a portable electronic device that is used on a plane such as a desk or the like for a relatively long time, such as an electronic dictionary or a notebook computer, the following inconvenience occurs. End up.
First of all, portable electronic devices of this type have recently been developed with various functions built in, and are frequently used. For this reason, it is naturally used at home, and is often used for taking lectures at universities, etc., or traveling by train. At this time, unlike a container for storing a cosmetic tool, since one case is provided with an input unit such as a keypad, it is easy to receive an external force from a fingertip and easily slip on a desk. Therefore, it is common that a non-slip rubber is attached to the lower surface of one case. In particular, in universities and the like, desks are slightly slanted, and vibrations during travel are received on a simple table in a train, so that it is easy to slip and rubber plays an important role.

  However, as a result of adopting the hinge structure, if the other case sinks into the lower surface of the one case, the one case partially rises from the desk due to the step between the two cases. Therefore, the rubber does not make sense, and it becomes easy to slip on the desk. As a result, it actually slipped during use and could not be used, or could slip from the desk and fall.

  The present invention has been made in view of such circumstances, and its purpose is to provide a foldable portable electronic device that is compact and excellent in portability and can be used safely without slipping on a desk. Is to provide.

The present invention provides the following means in order to solve the above problems.
The foldable portable electronic device according to the present invention is provided with an input unit, a first case main body placed on a plane, and a display panel for displaying information input by the input unit. The first case body and the second case body are connected to each other so as to be openable and closable while being disposed on the first case body side, and the second case body is connected to a predetermined angle or more A hinge portion that is rotated so as to be embedded in the lower surface side of the first case body when opened, and a plurality of anti-slip main anti-slip members that are fixed to the first case body so as to contact the plane. A non-slip sub-slip member fixed to the case body so as to come into contact with the plane when the second case body is opened at the predetermined angle, and the sub-slip member comprises: The second case body is While it is opening at higher angles from serial certain angle, and is characterized in that in contact with always the plane together with the main slip preventing member.

  In the foldable portable electronic device according to the present invention, first, a hinge portion that connects the first case body and the second case body so as to be openable and closable is disposed on the first case body side. Therefore, the protrusion of a hinge part can be suppressed and compactization can be achieved. Therefore, it is excellent in portability when not in use.

  On the other hand, when used, the first case body is first placed on a flat surface such as a desk. At this time, since a plurality of main anti-slip members are fixed to the first case body, the foldable portable electronic device itself does not slide on a plane. Subsequently, the second case main body is rotated through the hinge portion and gradually opened. Then, under the influence of the hinge part arrange | positioned at the 1st case main body side, the 2nd case main body will rotate so that it may sink into the lower surface side of a 1st case main body, if it opens more than a fixed angle. Therefore, the first case main body is lifted by the second case main body that has entered, so that the lower surface on the hinge part side is in a state of floating from the plane. Therefore, a part fixed to the hinge part side among several main anti-slip | skid members will float similarly, and will leave | separate from a plane.

However, when the second case body is opened at a certain angle, the sub-slip prevention member comes into contact with the flat surface. That is, at the same time that a part of the main anti-slip member floats, the sub anti-slip member comes into contact with the plane and plays a role of an anti-slip function instead of the main anti-slip member. In addition, the sub-slip member is always in contact with a flat surface while the second case body is opened at a certain angle or more.
Therefore, while the second case body is opened at a certain angle or more, the remaining part of the main non-slip member that does not float from the plane and continues to contact the plane, and the sub-slip The member reliably contacts the flat surface. Therefore, as in the case where the second case main body is closed, a reliable anti-slip function can be exhibited.

Therefore, even if an input operation is performed with the input unit provided in the first case body, the input operation is not slipped, so that a reliable input operation can be performed with peace of mind. Therefore, convenience can be improved and a high-quality electronic device that is easy for the user to handle can be provided.
Further, when the second case body is opened by a certain angle or more, the first case body is lifted by the second case body, so that it is inclined with respect to the plane. That is, only by opening the second case body, the surface on which the input unit is provided becomes a naturally inclined surface. Therefore, the user can perform the input operation very easily. In addition, since the second case body provided with the display panel is similarly inclined, the user can easily visually recognize the display panel. Also in these points, it is possible to provide a high-quality electronic device that is easy to handle for the user.

  Moreover, the foldable portable electronic device according to the present invention is the foldable portable electronic device according to the present invention, wherein the sub-slip prevention member is fixed in a strip shape so as to be in line contact with the plane. It is characterized by.

  In the foldable portable electronic device according to the present invention, the sub-slip prevention member is in line contact with the plane, so that the posture during use is more stable. Therefore, the anti-slip function can be exhibited more efficiently.

  Moreover, the foldable portable electronic device according to the present invention is a foldable portable electronic device according to the present invention, wherein a plurality of the sub-slip prevention members are fixed so as to come into multipoint contact with the plane. It is characterized by.

  In the foldable portable electronic device according to the present invention, since the sub-slip prevention member makes multiple contact with the flat surface, the posture during use is stabilized. Therefore, the anti-slip function can be exhibited more efficiently.

  In the foldable portable electronic device according to the present invention, in the foldable portable electronic device according to the present invention, the sub-slip prevention member is fixed to the second case body so as to be freely drawn out. It is characterized by this.

  In the foldable portable electronic device according to the present invention, since the sub-slip prevention member can be pulled out from the second case body, the lifting amount of the first case body can be changed. That is, the inclination angle of the first case body can be changed according to the situation. For example, the inclination angle can be increased as the amount of the sub-slip prevention member pulled out is increased. Therefore, the user can perform an input operation at an optimum inclination angle suitable for him. Therefore, the operability can be further improved.

  Further, the foldable portable electronic device according to the present invention is the foldable portable electronic device according to the present invention, wherein the sub-slip preventing member is opened as the second case body exceeds the predetermined angle. The surface is formed in a curved shape so as to have an outline line in which the radius of rotation from the rotation center of the hinge portion gradually increases.

  In the foldable portable electronic device according to the present invention, since the sub-slip prevention member is formed like a cam, the lifting amount of the first case body is increased as the second case body is opened more than a certain angle. Can be bigger. That is, the inclination angle can be increased only by adjusting the opening angle of the second case body. Therefore, the user can perform an input operation at an optimum inclination angle suitable for him. Therefore, the operability can be further improved.

  Further, the foldable portable electronic device according to the present invention is the foldable portable electronic device according to the present invention, wherein the sub-slip prevention member opens the second case body beyond the certain angle. The surface is formed in a polyhedral shape so that the opening angle is maintained at every predetermined angle.

In the foldable portable electronic device according to the present invention, since the surface of the sub-slip prevention member is formed in a polyhedral shape, the posture is stable at every predetermined angle when the second case body is opened at a certain angle or more. To do. That is, each time the opening angle of the second case main body is changed, each surface of the sub-slip prevention member sequentially comes into surface contact with the flat surface, so that the posture is stabilized each time. Therefore, the second case main body can be made still more without blurring or the like. Therefore, the display panel can be easily seen and the visibility can be improved.
Furthermore, since the sub-slip prevention member makes surface contact with the flat surface, the contact resistance can be increased. Therefore, the anti-slip effect can be further enhanced.

  According to the foldable portable electronic device according to the present invention, it is compact and excellent in portability, and can be used safely without slipping on a flat surface such as a desk, and a reliable input operation can be performed. . Thus, an easy-to-use and high-quality electronic device can be obtained.

  Hereinafter, an embodiment of a foldable portable electronic device according to the present invention will be described with reference to FIGS. In this embodiment, an electronic dictionary will be described as an example of a folding portable electronic device.

As shown in FIGS. 1 to 4, the electronic dictionary 1 of the present embodiment includes a bottom case (first case main body) 2 and a top case (second case main body) 3 via a hinge portion 4. The portable electronic device is a portable portable electronic device that is foldable so that it can be opened and closed. In other words, when not in use, the top case 3 can be closed and folded so that it is thin and compact, and can be easily stored and carried in a bag, for example. In use, the top case 3 is rotated with respect to the bottom case 2 so that the angle of the top case 3 can be adjusted so as to match the user's eyes.
The electronic dictionary 1 is used with the bottom case 2 placed on a plane S such as a desk.

A part of the bottom case 2 and the top case 3 are both formed in a thin box shape from a metal material such as plastic, aluminum, and stainless steel. Among these, the bottom case 2 includes a keypad 10 in which a plurality of keys 10a that can be pressed with a fingertip are arranged in a predetermined keyboard layout (keyboard layout), a plurality of function keys 11 that can also be pressed with a fingertip, and various types of keys. An input unit 13 including function buttons 12 is provided.
On the other hand, the top case 3 is provided with a display panel 14 for displaying various information input by the input unit 13 over almost the entire surface, and a transparent protective cover (for example, a plastic cover such as plastic). ) Is visible. The display panel 14 is a color or monochrome liquid crystal panel of about 5 inches, for example. Further, the protective cover 15 is not essential.

  In the bottom case 2, a circuit board 24 on which a control unit 20, a memory 21, a rechargeable battery 22, a speaker 23, and the like are mounted is incorporated as shown in FIG. The control unit 20 includes an arithmetic processing unit such as a CPU, a ROM that stores various programs as the electronic dictionary 1, a RAM that is a temporary storage medium, a display control unit that controls the display panel 14, and the like. Yes. The control unit 20 comprehensively configures each component based on a signal sent via the circuit board 24 when the plurality of keys 10a, the function keys 11, and the function buttons 12 of the keypad 10 are pressed. The electronic dictionary 1 is controlled to operate various functions.

  Further, the control unit 20 has a function of outputting sound information stored in the memory 21 from the speaker 23. In addition, the audio | voice output from the speaker 23 is output outside from the several sound hole 2a provided in the surface of the bottom case 2, as shown in FIG.3 and FIG.4. Thereby, for example, it is also possible to learn by listening to the searched foreign language with the correct voice (native voice). At this time, the control unit 20 also displays audio output information on the display panel 14. Therefore, the user can check the search contents with his eyes and ears. The control unit 20 displays not only the voice output information but also the key 10a pressed with the fingertip, and other various information (for example, dictionary contents, word search contents, remaining amount of the rechargeable battery 22, time and date, etc. ) Can be displayed.

  When the bottom case 2 and the top case 3 are connected, the hinge part 4 is provided so as to be arranged on the bottom case 2 side as shown in FIG. The hinge portion 4 is rotated so as to be embedded in the lower surface side of the bottom case 2 when the top case 3 is opened from the closed state by a certain angle (approximately 90 degrees).

  A plurality of non-slip rubbers (main anti-slip members) 30 that are in contact with the plane S are fixed to the lower surface of the bottom case 2. This non-slip rubber 30 is a rubber having a predetermined friction coefficient, and in this embodiment, an example is shown in which a total of four, two locations on the hinge portion 4 side and two locations on the keypad 10 side, are fixed. . However, it is not limited to four.

Similarly, as shown in FIGS. 1 and 2, a non-slip rubber (sub-slip prevention member) 31 is also fixed to the top case 3. The non-slip rubber 31 is fixed from the upper surface to the end surface, and comes into contact with the plane S when the top case 3 is opened at a certain angle. That is, the non-slip rubber 31 is always flat with the anti-slip rubber 30 on the bottom case 2 side while the top case 3 is opened from a certain angle to an angle larger than that (approximately 90 to 180 degrees). To come into contact.
Note that two anti-slip rubbers 31 of the present embodiment are fixed at intervals along the width direction of the top case 3. Therefore, multiple points of contact with the plane S are made.

The anti-slip rubber 31 on the top case 3 side and the anti-slip rubber 30 on the bottom case 2 side may be formed of the same material or different materials. . Any material that has a predetermined coefficient of friction and can be expected to have an anti-slip effect may be freely selected and formed.
In particular, in the present embodiment, a case where a plurality of the non-slip rubber 30 and the non-slip rubber 31 are fixed is taken as an example, but even if the non-slip rubber is the same, the material may be changed depending on the mounting position. I do not care. In order to exert the maximum anti-slip effect, materials may be properly used depending on the situation.

Next, the case where the electronic dictionary 1 configured in this way is used will be described below.
First, the state before use will be briefly described. In the electronic dictionary 1 of the present embodiment, the hinge portion 4 that connects the bottom case 2 and the top case 3 so as to be openable and closable is disposed on the bottom case 2 side. . Therefore, the protrusion of the hinge part 4 can be suppressed and a compact design can be achieved.
This point will be described with reference to the drawings. The upper stage shown in FIG. 6 is an electronic dictionary when the hinge part 4 protruding outward is temporarily used, and the lower stage shows the electronic dictionary 1 of the present embodiment. As shown in FIG. 6, it is possible to eliminate the distance L <b> 3 where the hinge portion 4 protrudes to the outside when the two cases 2 and 3 are closed and unused.

In addition, since the hinge portion 4 is disposed on the bottom case 2 side, the position of the display panel 14 provided on the top case 3 can be shifted to the hinge portion 4 side (right side with respect to the paper surface).
More specifically, when a hinge structure protruding outward is employed, a cutout hole 3a for the hinge portion 4 needs to be formed on one end side of the top case 3 as shown in FIG. For this reason, when the display panel 14 is arranged, the display panel 14 has to be arranged at a distance L4 from the lower end of the top case 3 in consideration of the notch 3a.
On the other hand, in the case of the present embodiment, the cutout hole 3a is unnecessary, and therefore, as shown in FIG. 8, only a distance L5 that is much smaller than the distance L4 is opened from the lower end of the top case 3. The display panel 14 can be arranged. That is, the display panel 14 can be arranged in a state of being shifted toward the lower end side of the top case 3 by the difference between the distance L4 and the distance L5. Therefore, the horizontal width of the top case 3 can be shortened accordingly.

  As a result, as shown in FIG. 6, the lateral width of the top case 3 can be made shorter by a distance L6 than the conventional case. Therefore, the horizontal width of the entire electronic dictionary 1 can be shortened from L7 to L8, and compactness can be achieved. Therefore, portability when not in use can be improved.

Next, the case where the electronic dictionary 1 is used will be described.
First, as shown in FIG. 9, the bottom case 2 is placed on a plane S such as a desk. At this time, since the four anti-slip rubbers 30 are fixed to the bottom case 2, the electronic dictionary 1 does not slide on the plane S due to the contact of the four anti-slip rubbers 30.
Subsequently, the closed top case 3 is rotated through the hinge portion 4 and gradually opened. Then, the top case 3 is affected by the hinge portion 4 arranged on the bottom case 2 side, and when a further angle is opened from the state of opening at a certain angle shown in FIG. 10, as shown in FIG. The bottom case 2 rotates so as to sink into the lower surface side. Therefore, since the bottom case 2 is lifted by the top case 3 that has entered, the lower surface on the hinge portion 4 side is in a state of floating from the plane S. Therefore, of the four anti-slip rubbers 30, the two anti-slip rubbers 30 fixed to the hinge part 4 side float in the same manner and are separated from the plane S.

  However, as shown in FIG. 10, when the top case 3 is opened at a certain angle, the non-slip rubber 31 fixed to the top case 3 comes into contact with the plane S. That is, a part of the non-slip rubber 30 on the bottom case 2 side (two on the hinge part 4 side) floats, and at the same time, the non-slip rubber 31 on the top case 3 side comes into contact with the plane S and the slip that has floated. Instead of the stop rubber 30, it plays the role of an anti-slip function. Moreover, as shown in FIG. 11, the non-slip rubber 31 on the side of the top case 3 is always in contact with the plane S while the top case 3 is opened at a certain angle or more.

Therefore, while the top case 3 is opened at a certain angle or more, the remaining two of the non-slip rubber 30 on the bottom case 2 side that does not float from the plane S and continues to contact the plane S, and The non-slip rubber 31 on the top case 3 side is surely in contact with the plane S. Therefore, as in the case where the top case 3 is closed, a reliable anti-slip function can be exhibited.
In particular, since there are two non-slip rubbers 31 on the top case 3 side, the flat surface S comes into multipoint contact. Therefore, the posture is stabilized without the electronic dictionary 1 wobbling. Therefore, the anti-slip function can be exhibited more efficiently.

As a result, even if an input operation is performed with the input unit 13 such as the key top 10 provided in the bottom case 2, the electronic dictionary 1 itself does not slide on the plane S, so that a reliable operation can be performed with peace of mind. Can do. Therefore, convenience can be improved and a high-quality electronic device that is easy for the user to handle can be provided.
Further, when the top case 3 is opened by a certain angle or more, the bottom case 2 is lifted by the top case 3, so that the top case 3 is inclined with respect to the plane S at an inclination angle θ. That is, only by opening the top case 3, the surface on which the input unit 13 is provided is naturally inclined. Therefore, the user can perform the input operation very easily. In addition, since the top case 3 provided with the display panel 14 is similarly inclined, the user can easily visually recognize the display panel 14. Also in these points, it is possible to provide a high-quality electronic device that is easy to handle for the user.

In the above embodiment, the case where two non-slip rubbers 31 are fixed to the top case 3 side is described as an example, but the present invention is not limited to this case. For example, as shown in FIGS. 12 and 13, only one anti-slip rubber 31 may be fixed. However, when the top case 3 is opened and the non-slip rubber 31 comes into contact with the flat surface S, it comes into contact with only one point. Therefore, in terms of stability, it is preferable to fix two at intervals as in the above embodiment, rather than fixing only one. Alternatively, three or more may be fixed. That is, it is preferable that the non-slip rubber 31 is configured to make multipoint contact with the plane S.
Even when the anti-slip rubber 31 is formed so as to make point contact with the plane S (for example, the tip of the anti-slip rubber 31 is formed like a spherical surface) and a plurality of these are fixed to the top case 3, Since point contact can be ensured, it is also included in the configuration of multipoint contact.

  Furthermore, as shown in FIGS. 14 and 15, the non-slip rubber 31 may be fixed in a strip shape so as to be in line contact with the plane S. Even in this case, the posture when the top case 3 is opened is stabilized as in the case where two anti-slip rubbers 31 are fixed. Therefore, the same operational effects as those of the above embodiment can be obtained.

Moreover, in the said embodiment, as shown in FIG. 16, you may fix the antiskid rubber 31 with respect to the top case 3 so that extraction is possible. In FIG. 16, a non-slip rubber 31 formed in a belt shape is illustrated.
In order to make it freely drawable, for example, as shown in FIG. 17, a guide plate 31 a and a stopper 31 b may be integrally formed on the non-slip rubber 31. Then, a guide hole (not shown) may be formed on the top case 3 side, and the non-slip rubber 31 may be attached so that the guide plate 31a slides in the guide hole. By comprising in this way, a user can pull out the non-slip rubber 31 freely. In addition, since the stopper 31b contacts the inner surface of the top case 3 when pulled out to the maximum, the anti-slip rubber 31 does not fall out.

  Thus, the lifting amount of the bottom case 2 can be changed by making the non-slip rubber 31 freely drawable. That is, the inclination angle θ of the bottom case 2 shown in FIG. 11 can be changed according to the situation. For example, the inclination angle θ can be increased as the pull-out amount of the non-slip rubber 31 is increased. Therefore, the user can perform an input operation at an optimum inclination angle θ suitable for him. Therefore, the operability can be further enhanced.

Moreover, in the said embodiment, as shown in FIG. 18, you may curve the surface of the non-slip | skid rubber 31 so that the role of a cam may be played. Specifically, as the top case 3 opens beyond a certain angle, the surface may be curved so as to have an outer shape line in which the rotation radius R from the rotation center G of the hinge portion 4 gradually increases.
Thus, by forming the non-slip rubber 31 like a cam, the lift amount of the bottom case 2 can be increased as the top case 3 is opened at a certain angle or more as shown in FIG. That is, the inclination angle θ of the bottom case 2 can be gradually increased only by adjusting the opening angle of the top case 3. Therefore, the user can perform an input operation at an optimum inclination angle θ suitable for himself / her and can further improve the operability.

Moreover, in the said embodiment, as shown in FIG. 20, you may form the surface in a non-slip rubber 31 in multiple sides.
By forming the non-slip rubber 31 in a multi-face shape as described above, when the top case 3 is opened at a certain angle or more, the posture is stabilized at every predetermined angle as shown in FIG. That is, each time the opening angle of the top case 3 is changed, each surface of the non-slip rubber 31 sequentially comes into surface contact with the plane S, so that the posture is stabilized each time. Therefore, the top case 3 can be made still more stationary without blurring. Therefore, the display panel 14 becomes easy to see and visibility can be improved. Furthermore, since the non-slip rubber 31 makes surface contact with the plane S, the contact resistance can be increased. Therefore, the anti-slip effect can be further enhanced.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in each of the embodiments described above, the portable electronic device has been described as the electronic dictionary 1, but is not limited to the electronic dictionary 1, and is a folding type that is used by being placed on a plane S such as a desk. If there is, it will not be specifically limited. For example, a portable information terminal such as a PDA or a notebook personal computer may be used.
In addition, as an example of the anti-slip member, the anti-slip rubbers 30 and 31 have been described as examples, but the non-slip member is not limited to rubber. For example, it may be formed using a resin material having a predetermined viscosity.
