[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a portable computer adopting a handwriting input method, and more particularly to a structure for tilting a housing at an angle at which an input screen can be easily viewed.

[0002]

2. Description of the Related Art In order to realize easy-to-use operability, various types of portable information processing apparatuses used for business or personal information management adopt a pen input method.

This type of information processing apparatus has a flat box-shaped casing. The housing has a bottom wall and an upper wall facing the bottom wall, and a display opening is formed in the upper wall. A liquid crystal display device is housed inside the housing. The liquid crystal display device has a display screen for displaying various information such as a schedule and an address, and a tablet is arranged on the display screen. The tablet has a transparent input screen, and the input screen is exposed to the outside of the housing through the display opening.

The input screen has various icons for switching functions and display modes and a handwriting input area. Therefore, various editing or input operations can be performed by pressing a desired icon on the input screen with a pen or by inputting information such as characters and figures by hand in the input area.

[0005] By the way, a pen-input type information processing apparatus includes:
There may be a usage pattern in which the input operation is performed by holding the housing by hand, and a usage pattern in which the input operation is performed while the housing is placed on a mounting surface such as a tabletop. Therefore, in the conventional information processing apparatus, a stand is installed on the bottom wall of the housing, and when the housing is placed on the mounting surface and an input operation is performed, the housing is tilted at an angle that makes it easy to see the input screen. Models are known.

[0006] The stand is rotatably supported by the housing between a storage position where the stand is stored along the bottom wall of the housing and a use position where the stand extends in a direction away from the bottom wall.
A lock arm is provided between the stand and the bottom wall of the housing to adjust the tilt angle of the housing determined by the rotation angle of the stand in a plurality of stages, and the position of the lock arm is adjusted. By adjusting, the inclination angle of the housing can be changed stepwise according to the user's preference and the use environment of the device.

[0007]

SUMMARY OF THE INVENTION In a use mode in which a housing is placed on a mounting surface to perform an input operation, in order to realize a reliable input operation with a pen, the inclination angle of the housing is adjusted steplessly. It is desirable to make it possible. As a specific configuration for realizing this, a friction brake mechanism is provided on the pivot portion of the stand, and when the stand is turned to the use position, a friction force is added, so that the stand can freely rotate. It can be restricted.

In this case, the rotation angle of the stand is large,
In a usage mode in which the inclination angle of the housing with respect to the mounting surface is close to 60 °, the direction of the action of the external force applied to the housing when the input screen is pressed with a pen substantially coincides with the direction of the stand. The external force applied can be received by the stand.

However, in a usage mode in which the rotation angle of the stand is small and the inclination angle of the housing with respect to the mounting surface is smaller than 35 °, the direction of action of the external force applied to the housing when the input screen is pressed with a pen is reduced. It differs greatly from the direction of the stand. For this reason, the stand is subjected to a large external force that attempts to rotate the pivotal support portion toward the storage position, and this external force easily overcomes the frictional force that restricts the free rotation of the stand. There can be.

As a result, there arises a problem that the stand undesirably returns to the storage position at the time of the input operation with the pen, which hinders an accurate input operation. Further, in a usage mode in which an input operation is performed by holding the housing by hand, the user grasps the periphery of the housing with the fingertip of the hand without the pen,
This case will be supported. At this time, in recent information processing apparatuses, the input screen is enlarged for the purpose of enhancing input operability and making it easier to view information. Therefore, a sufficient space for putting a fingertip around the input screen is secured. Can not do. In addition, since the top and bottom walls of the housing are often formed smoothly, fingertips are apt to slip when performing input operations while holding the housing by hand. There is also the problem of instability.

A first object of the present invention is to make it possible to surely prevent the stand from returning to the storage position when the input screen is pressed, even though the rotation angle of the stand can be adjusted steplessly. An object of the present invention is to provide an information processing device capable of performing an accurate input operation.

[0012] A second object of the present invention is to adjust the rotation angle of the stand steplessly, to maintain good input operability, and to perform input operation by holding the housing by hand.
An object of the present invention is to provide an information processing device which can be used as a tool for a stand and can firmly support a housing by hand.

A third object of the present invention is that, in addition to the first object, when performing an input operation while holding the housing by hand, the stand can be used as a handle and the housing can be used by hand. An object of the present invention is to provide an information processing device that can be firmly supported.

[0014]

In order to achieve the first object, an information processing apparatus according to the present invention has a bottom wall and an upper wall facing the bottom wall, and inputs data to the upper wall. A housing on which an input screen pressed during operation is arranged; a storage position stored along the bottom wall of the housing, and a use position protruding in a direction away from the bottom wall so as to be rotatable. A stand that is supported by the housing and inclines the housing at an angle that makes it easy to view the input screen when the housing is placed on the mounting surface; free rotation of the stand by applying a frictional force when the stand rotates Adjusting means for restricting the movement and adjusting the rotation angle of the stand with respect to the housing in a stepless manner. The housing is characterized in that it has a stopper that can advance between the stand and the bottom wall when the stand is rotated at a desired angle toward the use position.

In such a configuration, when the input operation is performed with the housing placed on the mounting surface, when the stand is rotated from the storage position to the use position, the stand projects from the bottom wall of the housing. Therefore, the stand comes into contact with the mounting surface, and the housing is inclined according to the rotation angle of the stand. At this time, the stand is held at a desired rotation angle by the frictional force applied to the stand, so that the inclination angle of the housing determined by the rotation angle of the stand can be adjusted steplessly.
This adjustment operation can be performed over a wide range so as to correspond to the user's preference and the use environment of the apparatus.

When the stand is rotated at a desired angle and the stopper is advanced between the stand and the bottom wall of the housing, the stopper is sandwiched between the stand and the bottom wall, and is stored. The rotation of the stand toward the position is limited. Therefore, even when the input screen is pressed and an input operation is performed in a state where the housing is inclined on the mounting surface, the stand does not return to the storage position, and the posture of the housing at the time of the input operation is changed. Stabilize.

In order to attain the second object, a ninth aspect is provided.

A storage position that is stored along and a use position that protrudes in a direction away from the bottom wall is rotatably supported by the housing,
When the housing is placed on the mounting surface, the input screen is tilted at an angle that makes it easy to see the input screen, and a hand-holding part is formed to allow the user to pass the hand when performing the input operation by holding the housing by hand. Adjusting means for restricting free rotation of the stand by applying a frictional force when the stand is rotated, and for continuously adjusting the rotation angle of the stand with respect to the housing. I have. The housing includes a stopper that is detachably locked to the stand from the side opposite to the bottom wall of the housing when the stand is rotated to a use position where a hand can be inserted into the handle portion. It is characterized by having.

In such a configuration, when the input operation is performed with the housing placed on the mounting surface, when the stand is rotated from the storage position to the use position, the stand projects from the bottom wall of the housing. Therefore, the stand comes into contact with the mounting surface, and the housing is inclined according to the rotation angle of the stand. At this time, the stand is held at a desired rotation angle by the frictional force applied to the stand, so that the inclination angle of the housing determined by the rotation angle of the stand can be adjusted steplessly. Can be performed over a wide range so as to correspond to the user's preference and the use environment of the apparatus.

In order to perform an input operation while holding the housing by hand, the stand is rotated by a desired angle from the storage position to the use position, and the hand is passed through the handle of the stand. Then, this hand is guided between the stand and the bottom wall of the housing to the peripheral edge of the housing, and the fingertip of the hand grasps the peripheral edge of the housing.
At this time, if the stopper of the housing is hooked on the stand, the rotation of the stand in the direction away from the bottom wall is restricted, and the positional relationship between the handle portion of the stand and the housing is kept constant. For this reason, even if the fingertip is separated from the peripheral edge of the housing at the time of the input operation, the hand does not fall out of the handle of the stand, and the housing can be firmly supported by the hand.

[0020] In order to achieve the third object, a first aspect is provided.
The information processing apparatus described in 1 has a bottom wall and an upper wall facing the bottom wall, and a housing on which an input screen pressed at the time of an input operation is arranged; and a bottom wall of the housing. Is supported by the housing so as to be rotatable over a storage position along which the storage position is stored, and a use position extending in a direction away from the bottom wall. When the housing is mounted on the mounting surface, the input screen is displayed. A stand having a handle portion formed to allow the hand to pass through when the housing is tilted at an easy-to-view angle and an input operation is performed by gripping the housing with a hand; a frictional force is applied when the stand rotates. Adjustment means for restricting the free rotation of the stand by doing so and adjusting the rotation angle of the stand with respect to the housing in a stepless manner.

The housing has a first stopper which can be advanced between the stand and the bottom wall in a state where the stand is rotated by a desired angle toward the use position;
A second stopper that is detachably locked to the stand from the side opposite to the bottom wall of the housing when the stand is rotated to a use position where a hand can be inserted into the handle portion. It is characterized by.

In such a configuration, when the input operation is performed with the housing placed on the mounting surface, when the stand is rotated from the storage position to the use position, the stand projects from the bottom wall of the housing. Therefore, the stand comes into contact with the mounting surface, and the housing is inclined according to the rotation angle of the stand. At this time, the stand is held at a desired rotation angle by the frictional force applied to the stand, so that the inclination angle of the housing determined by the rotation angle of the stand can be adjusted steplessly. Can be performed over a wide range so as to correspond to the user's preference and the use environment of the apparatus.

When the first stopper is advanced between the stand and the bottom wall of the housing while the stand is rotated at a desired angle, the first stopper is moved between the stand and the bottom wall. The stand is pinched so that the rotation of the stand toward the storage position is restricted. Therefore, even when the input screen is pressed and an input operation is performed in a state where the housing is inclined on the mounting surface, the stand does not return to the storage position, and the posture of the housing at the time of the input operation is changed. Stabilize.

To perform an input operation while holding the housing by hand, the stand is rotated by a desired angle toward the use position.
Pass the handle of this stand. Then, this hand is guided between the stand and the bottom wall of the housing to the peripheral edge of the housing, and the fingertip of the hand grasps the peripheral edge of the housing. At this time, if the second stopper of the housing is hooked on the stand, the rotation of the stand in a direction away from the bottom wall is restricted, and the positional relationship between the handle portion of the stand and the housing is kept constant. For this reason, even if the fingertip is separated from the peripheral edge of the housing at the time of the input operation, the hand does not fall out of the handle of the stand, and the housing can be firmly supported by the hand.

When various elements such as icons displayed on the input screen 19 are pressed with the stylus pen 21, desired menus corresponding to these elements are activated, and various editing or input operations can be performed.

The housing 2 has a pen housing 22.
The pen housing 22 has an insertion opening 23 opened in the first side wall 5 a of the housing 2, and the stylus pen 21 is housed in the pen housing 22 through the insertion opening 23 so as to be able to be taken out.

As shown in FIG. 3 and FIG.
A folding stand 25 is provided. Stand 2
Numeral 5 is for tilting the housing 2 at an angle at which the input screen 19 is easy to see when the portable computer 1 is used on a mounting surface 26 such as a table top.

The stand 25 is formed by bending a metal shaft having a circular cross section into a crank shape. As shown in FIG. 4, a pair of rotating shafts 28a and 28b and a pair of legs 2 are provided.
9a and 29b and a connecting portion 30 are provided. The rotating shafts 28a and 28b are located at both ends of the stand 25,
The housing 2 is coaxially spaced apart in the width direction. The legs 29a, 29b extend in a direction substantially perpendicular to the ends of the rotating shafts 28a, 28b, and face each other in the width direction of the housing 2. The connecting portion 30 is connected to the leg 29
a, 29b. The connecting portion 30 extends along the width direction of the housing 2, and a rubber non-slip tube 31 is attached to an outer peripheral surface of the connecting portion 30.

Has a flat bracket body 34 and a support portion 35 formed at one end of the bracket body 34.

The supporting portion 35 is curved in an arc shape in cross section along the outer peripheral surface of the rotating shaft portions 28a, 28b. The rotating shaft portions 28a, 28b are inserted through the inside of the supporting portion 35. I have. The support portion 35 is caulked radially inward with the rotating shaft portions 28a and 28b inserted therethrough.
As a result, the support shafts 35a and 28b
Are connected so as to be rotatable around the axis.

In this case, the inner peripheral surface of the support portion 35 is slidably in contact with the outer peripheral surfaces of the rotating shaft portions 28a and 28b with a predetermined frictional force. The free rotation of the stand 25 with respect to the bracket 33 is restricted. Therefore, in the case of this embodiment,
The support portion 35 of the bracket 33 constitutes an adjusting means for adjusting the rotation angle of the stand 25 steplessly.

The bottom wall 3 of the housing 2 has a mounting seat 37 having an increased thickness for receiving the bracket 33. The mounting seat 37 has a plurality of screw holes 38 opened in the bottom wall 3, and the bracket body 34 is fixed to the screw holes 38 via screws 39.

For this reason, the stand 25 is
The storage positions where the legs 29a, 29b and the connecting portion 30 are stored along the bottom wall 3 of the housing 2 with the a, 28b as a fulcrum, and the legs 29a, 29b and the connecting portion 30 It is supported by the housing 2 so as to be rotatable over a use position where it is rotated by an angle α in a direction away from the bottom wall 3. The free rotation of the rotating shaft portions 28a and 28b of the stand 25 is limited by the frictional force applied to the outer peripheral surface of the stand 25. Therefore, the stand 25 is in the state stored in the storage position or in the use position. It is held in one of the states where it is turned at a desired angle.

The bracket 33 is covered by a stand cover 40, and the stand cover 40 is detachably supported by the bottom wall 3 of the housing 2. The stand 25 has a handle 41. As shown in FIG. 7, the handhold 41 is used to pass the hand H when carrying out an input operation while holding the housing 2 of the portable computer 1 with the hand H. The handle portion 41 is defined by a space surrounded by the legs 29a and 29b and the connection portion 30. When the hand is passed through the handle portion 41, the non-slip tube 31 of the connection portion 30 is Back H1 of hand H
It comes in contact with.

As shown in FIG. 3, the housing 2 has a bottom wall 3
It has first and second convex portions 43a and 43b projecting upward. The first and second protrusions 43a and 43b are arranged apart from each other in the depth direction of the housing 2 and extend along the width direction of the housing 2. The first and second projections 43a and 43b have contact surfaces 44a and 44b that come into contact with the mounting surface 26 when the portable computer 1 is mounted on the mounting surface 26. Contact surface 44
a and 44b are located on substantially the same plane, and project in a direction away from the bottom wall 3.

The first and second convex portions 43a and 43b are
On the bottom wall 2, they are located on both sides of the stand 25. These first and second convex portions 43a, 43b
Constitutes a concave storage section 45 in cooperation with the bottom wall 3 of the housing 2, and the stand 25 is located in the storage section 45.

Therefore, as shown by a two-dot chain line in FIG.
When the stand 25 is rotated to the storage position, the contact surfaces 44a and 44b of the first and second protrusions 43a and 43b project more in the direction away from the bottom wall 3 than the stand 25, and the stand 25 45. Therefore, when the housing 2 is placed on the mounting surface 26 with the stand 25 stored, only the contact surfaces 44a and 44b come into contact with the mounting surface 26, and the housing 2
The rattling is prevented.

As shown in FIG. 3, when the portable computer 1 is used while being mounted on the mounting surface 26, the housing 2 is rotated while the stand 25 is rotated at a desired angle toward the use position. , The corner defined by the bottom wall 3 of the housing 2 and the second side wall 5b and the non-slip tube 31 of the stand 25 come into contact with the mounting surface 26, respectively. Therefore, the housing 2 of the portable computer 1 is inclined at an inclination angle β determined by the rotation angle α of the stand 25 with respect to the mounting surface 26. In the case of the present embodiment, the inclination angle β of the housing 2 is 30. It can be adjusted steplessly within the range of ° to 60 °.

A rubber non-slip sheet 46 is provided at a corner defined by the bottom wall 3 of the housing 2 and the second side wall 5b. As shown in FIG.
Has a pair of stopper support portions 48a and 48b. The stopper support portions 48a and 48b are arranged apart from each other in the width direction of the housing 4 between the mounting seat portions 37. The stopper support portions 48a and 48b are connected to the rotating shaft portions 28a and 28b of the stand 25 and the leg portions 29a and 29.
b and is located near the corner 49 defined by b.

Each of the stopper support walls 48a and 48b has a guide groove 51. The guide groove 51 extends in the width direction of the housing 2 and the corner 4 of the stand 25.
9 has an opening 52 that is open to the outside. A stopper 53 is supported in the guide groove 51. The stopper 53 can be manually slid over a first position protruding from the opening 52 of the guide groove 51 and a second position retracted into the opening 52.

Therefore, as shown in FIG.
When the stopper 53 is slid from the second position to the first position in a state where the stopper 53 is rotated at a desired angle, for example, 35 °, from the storage position to the use position, the stopper 53 Corner 49 and bottom wall 3 of housing 2
, And are sandwiched between the two.

Therefore, in a state where the stand 25 is rotated 35 ° toward the use position, as long as the stopper 53 is slid to the first position, the stand 25 can be rotated toward the storage position. However, the rotation angle of the stand 25 with respect to the housing 2 is fixedly determined.

When the stand 35 is moved toward the use position,
In the state where the stopper 53 is rotated by 5 °, the stopper 53 is moved to the first position.
When the slider is slid from the position to the second position, the stopper 53 is detached from between the corner 49 of the stand 25 and the bottom wall 3 of the housing 2. Therefore, the fixing of the stand 25 is released, and the stand 25 can be rotated toward the storage position.

As shown in FIG. 8C, a disk-shaped speaker 55 is housed inside the housing 2. The speaker 55 has a front surface 55 serving as a sound emitting portion at a corner defined by the first side wall 5a and the second side wall 5b of the housing 2.
a is housed in the housing 2 in a vertical position facing the second side wall 5b.

A ring-shaped speaker holder 56 is attached to the outer periphery of the speaker 55. The speaker holder 56 is made of a flexible material such as a rubber-like elastic body.
Are formed. The base 7 is inserted into the fitting groove 57.
Speaker support wall 58 extending upward from the bottom wall 3 of the speaker
And a second extending downward from the upper wall 4 of the base cover 8.
Are fitted to each other, and the speaker 55 is supported by the housing 2 by this fitting.

As best shown in FIG. 8C,
The speaker 55 is connected to the second side wall 5 b inside the housing 2.
It is adjacent to. Upper wall 4 connected to second side wall 5b
A plurality of first speaker holes 60 are opened at the front end of the first speaker hole 60. The first speaker holes 60 are arranged at positions corresponding to the outer peripheral portion of the speaker 55, and are arranged in a line in the width direction of the housing 2. A plurality of second speaker holes 61 are opened at the end of the second side wall 5b. The second speaker holes 61 are arranged in a matrix at a position facing the front surface 55a of the speaker 55. Therefore, the sound from the speaker 55 is emitted to the outside of the housing 2 through the first and second speaker holes 60 and 61.

Therefore, in a case where the bottom wall 3 and the first to fourth side walls 5a to 5d of the housing 2 are covered by the case, such as when the portable computer 1 is housed in a portable case (not shown). However, the sound from the speaker 55 is emitted to the outside of the housing 2 through the first speaker hole 60, so that the sound emitted from the speaker 55 is not blocked by the case.

In the portable computer 1 having such a structure, when the housing 2 is placed on the placement surface 26 and an input operation is performed, the stand 25 is rotated by a desired angle from the storage position to the use position. The housing 2 is tilted at an angle that makes it easy to see the input screen 19 according to the user's preference and usage environment.

That is, as shown in FIGS. 3 and 6, when the housing 2 is placed on the mounting surface 26 while the stand 25 is rotated by a desired angle toward the use position, the bottom wall of the housing 2 3 and the non-slip tube 31 of the stand 25 respectively contact the mounting surface 26, and the inclination angle β of the housing 2 based on the rotation angle α of the stand 25. Is determined. By changing the rotation angle α of the stand 25, the inclination angle β of the
It can be adjusted steplessly within the range of ° to 60 °.

In this case, as shown in FIG. 3, when the inclination angle β of the housing 2 is close to 60 °, the rotation angle α of the stand 25 with respect to the housing 2 is large.
Since the legs 29a and 29b of the base extend along the direction of action of the external force applied to the housing 2 when the input screen 19 is pressed with the stylus pen 21, the stand 25 can receive the external force. Therefore, the posture of the housing 2 is stabilized, and the housing 2 does not rattle during the input operation using the stylus pen 21.

On the other hand, as shown in FIG. 6, when the inclination angle β of the housing 2 is close to 30 °, the rotation angle α of the stand 25 is small, and the legs 29a, 29
The direction of b and the acting direction of the external force applied to the housing 2 when the input screen 19 is pressed with the stylus pen 21 greatly differ. Therefore, at the time of the input operation with the stylus pen 21, the stand 25 is rotated by the rotating shafts 28a and 28b.
When the external force overcomes the frictional force that holds the rotation shafts 28a and 28b at the desired rotation positions, the stand 25 retracts. Will return to position.

However, when the stand 25 is rotated by 35 ° toward the use position, the portable computer 1 having the above-described configuration can be configured such that the corner 49 of the stand 25 and the housing 2
And a stopper 53 which can advance between the bottom wall 3 and the bottom wall 3. Therefore, when the stopper 53 is slid to the first position when the inclination angle β of the housing 2 is close to 35 °, if the stopper 53 is slid to the corner 49 of the stand 25 and the bottom wall 3 of the housing 2. And the rotation of the stand 25 toward the storage position is hindered.

Therefore, even when the external force applied to the housing 2 when the input screen 19 is pressed by the stylus pen 21 exceeds the frictional force acting on the rotating shafts 28a and 28b, the stand 25 can be rotated by a desired amount. Held at an angle. Therefore, the posture of the housing 2 is stabilized, and the input operation can be reliably performed.

As shown in FIG. 7, in order to perform an input operation while holding the portable computer 1 by hand, first, the stand 25 is rotated by a desired angle from the storage position to the use position. The part 41 is the bottom wall 3 of the housing 2
Keep away from Next, the hand H without the stylus pen 21 is inserted into the handle 41 of the stand 25,
Place the back H1 of this hand H on the non-slip tube 3 of the stand 25
Hook on 1. At the same time, the fingertip of the hand H is guided to the fourth side wall 5d while the palm of the hand H is along the bottom wall 3 of the housing 2, and the peripheral edge of the housing 2 including the side wall 5d is grasped by the fingertip. Thus, the housing 2 is supported with the input screen 19 facing the user, and the input operation can be performed while the portable computer 1 is held by hand.

According to the portable computer 1,
