Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable data processing device, and is applied to, for example, a pen input type portable data processing device.
[0002]
[Prior art]
As shown in FIG. 5, a conventional pen input type portable data processing device includes a CPU (arithmetic unit) a, a liquid crystal display (display device) b, a tablet (pen input device) c, and a hard disk drive (storage device) d. , External input / output device e, DC-DC converter (power supply device) f, battery g, pen h, PC card slot i, forced air cooling device j, heat sink k, vent hole l, and power switch m. All of these, which are constituent elements of a pen-input type portable data processing device, are stored in one casing o. Further, such a pen input type portable data processing device is equipped with a high-performance CPU from the viewpoint of operability and versatility.
[0003]
[Problems to be solved by the invention]
In general, an arithmetic device is in a relationship in which performance and power consumption are proportional to each other, and as the performance of the arithmetic device increases, heat generation of the entire data processing device increases. Therefore, it is necessary to take measures for heat dissipation during use. In addition, since arithmetic devices, storage devices, and the like are vulnerable to water and dust, measures for waterproofing and dustproofing when carried are also required.
[0004]
Therefore, by not providing holes in the housing, we take measures to protect against water and dust when carrying, and to dissipate heat by transferring the heat inside the housing to the surface of the housing by heat conduction, so that we can take measures to dissipate heat during use. A method is conceivable. This method is effective for the stationary type. However, it is not possible to ensure comfortable usability for a portable type in which operation is generally performed while holding the housing with a hand.
[0005]
Therefore, in a conventional pen-input type portable data processing device, as shown in FIG. 5, a ventilation hole l is provided in the casing o, and air and outside air inside the casing are circulated to take measures for heat dissipation during use. On the other hand, waterproof and dust-proof measures are taken by a method using a portable case and a method using a shutter-type ventilation hole.
[0006]
However, the method using the portable case cannot provide comfortable usability because the case removed for securing the ventilation hole at the time of use becomes an obstacle. In addition, in the method of using the shutter type for the ventilation hole, the manual opening type forgets to open and close, and the automatic opening type complicates the opening / closing mechanism.
[0007]
In addition, since pen input devices and display devices are vulnerable to impacts, it is necessary to take measures for protecting the wound when carrying them.
[0008]
As a measure for protecting the wound when carrying, there are a method using a carrying case and a method of providing a protective cover on a pen input device / display device.
[0009]
However, with the method using the carrying case, the case removed at the time of use will not be able to provide comfortable usability, and even with the method of providing the protective cover, the protective cover removed at the time of use will be in the way and comfortable with the removable type. Can't provide good usability.
[0010]
For this reason, as shown in FIG. 6, a protective cover q fixed to the casing o with a hinge p is provided to take a measure for protecting the wound. The protective cover q protects the pen input device / display device when carried, and is fixed to the bottom surface side so as not to get in the way when used. However, in this case, since the ventilation hole cannot be arranged on the bottom surface, the ventilation hole is provided on the side surface.
[0011]
However, as the device becomes thinner, the area of the side surface becomes smaller, so that it is not possible to ensure a sufficient area of the ventilation holes for heat dissipation.
[0012]
Furthermore, since it is a common usage mode to carry it with you, it is necessary to take security measures when you carry it in case you leave it away when you carry it.
[0013]
For this reason, conventional pen input type portable data processing devices are protected by physical keys, protected by encryption input, or security measures by combining these so that a third party cannot easily operate. Although it is adopted, it is defenseless against extraction of PC cards (detachable cards conforming to PCMCIA such as SRAM cards and FLASH memory cards).
[0014]
Therefore, a conventional pen input type portable data processing apparatus adopts a method of adopting a special specification card and a method of attaching a physical key to the insertion hole of the PC card slot. However, the former method is expensive, and the latter method is complicated in structure.
[0015]
Furthermore, compared with the stationary type, the portable type is more susceptible to shock and vibration on the device, and the repair occurrence rate is high, so that the ease of repair is also required. In a conventional pen-input type portable data processing device, as shown in FIG. 5, all of the main body and peripheral devices are incorporated in one casing. Therefore, even if any peripheral device is broken, the case must be disassembled for repair.
[0016]
In addition, there is a risk of secondary destruction due to static electricity, so repair is not easy. Furthermore, when the performance is improved, the housing needs to be disassembled and there is a risk of destruction due to static electricity, so it is not easy to improve the performance.
[0017]
The present invention has been made in view of such points, and the object of the present invention is to provide a data processing device in which more sufficient heat dissipation measures are taken while maintaining a comfortable usability during use, It is another object of the present invention to provide a portable data processing device that has a waterproof and dust-proof measure with a simple structure while maintaining the effect of protecting the wound when carried.
[0018]
Furthermore, it provides a security effect with an inexpensive and simple structure, and also provides ease of repair.
[0019]

DETAILED DESCRIPTION OF THE INVENTION
A pen input type portable data processing apparatus according to an embodiment of the present invention will be described below with reference to FIGS.
[0026]
As shown in FIG. 1 and FIG. 2, a pen-input type portable data processing device includes a housing (first housing described in claims ) 1 and a housing (second housing described in claims). ) a 2 which constituent elements of the data processing device is stored separately in the housing 1 and the housing 2.
[0027]
The housing 1 houses a display device 11, a pen input device 12, and a power switch 14.
[0028]
That is, a rectangular opening is provided on the surface 1 a of the housing 1, and the display device 11 and the pen input device 12 are placed on the display device 11 in the opening. They are stored so as to overlap. Further, a power switch 14 is provided on the surface 1a, and a packing 13 is provided along the outer peripheral portion of the surface 1a.
[0029]
Inside the housing 2 are stored an arithmetic device 21, a heat sink 22, a storage device 23, an external input / output device 24, a PC card slot 25, a power supply device 26, a battery 27, and a forced air cooling device 28. The front surface 2a of the housing 2 is provided with a ventilation hole 2c and a pen storage portion 2d. The side surface 2b has a connector 24a of the external input / output device 24 and a PC card slot 25 as an external storage device. An insertion hole 25a is provided. The pen for input is stored in the pen storage portion 2d.
[0030]
The housing 1 and the housing 2 are made of a member resistant to external damage such as reinforced plastic and magnesium alloy.
[0031]
The housing 1 and the housing 2 are coupled by a hinge mechanism having two axes via a connecting member 3.
[0032]
That is, the housing 1 and the connecting member 3 are connected to each other by the first hinge mechanism 31 on the side surface of the housing 1 and one end of the connecting member 3. The hinge mechanism 31 can be rotated by 180 degrees or more. Further, the other end of the connecting member 3 and the center position portion in the height direction of the side surface 2 b of the housing 2 are connected to the connecting member 3 and the housing 2 by the second hinge mechanism 32. Since the hinge mechanism 32 is provided in the center position portion in the height direction of the side surface 2b of the housing 2, the rotation angle thereof can be opened up to 180 degrees. The central axes of the first hinge mechanism 31 and the second hinge mechanism 32 are arranged in parallel, and the length in the height direction of the connecting member 3 is the height of the one side surface 2b of the housing 2. About half.
[0033]
In the hinge mechanism having such a structure, when the first hinge mechanism 31 and the second hinge mechanism 32 are both opened, the casing 1, the casing 2, and the connecting member 3 are deployed in parallel (FIG. 1). The surface 1a of the housing 1, the surface 2a of the housing 2, and the surface 3a of the connecting member 3 are arranged in the same direction.
[0034]
Therefore, the casing 1 and the casing 2 can be changed from the arrangement when not in use as shown in FIG. 3A to the arrangement in use as shown in FIG. 3B by this hinge mechanism. In addition, the arrangement at the time of use shown in FIG. 3B can be changed to the arrangement at the time of carrying shown in FIG.
[0035]
In addition, when not in use, it means that it is not in use, and is a concept that includes not only when it is carried, but also when it is left on a desk, for example.
[0036]
A packing 33 is provided on the surface 3 a of the connecting member 3.
Further, the interconnection device 1x of the housing 1 and the interconnection device 2x of the housing 2 are connected by a cable passing through the hinge, thereby adopting a mutual interface.
[0037]
Each of the housing 1 and the housing 2 is provided with a locking hole so that it can be locked with a padlock (see FIG. 3A).
[0038]
The arithmetic device 21 and the heat sink 22 housed in the housing 1 are connected by a heat conductive material, and the heat generated in the arithmetic device 21 is guided to the heat sink 22. By the forced air cooling device 28, the outside air efficiently hits the heat sink 22 through the ventilation holes 2c, so that the heat induced in the heat sink 22 is cooled by air.
[0039]
-Portable form-
FIG. 3A shows the arrangement at the time of carrying.
[0040]
When carrying, the arrangement is such that the surface 1a of the housing 1 and the surface 2a of the housing 2 and the side surface 2b of the housing 2 and the surface 3a of the connecting member 3 face each other. Therefore, in this arrangement, all parts necessary for use are located inside.
[0041]
That is, the display device 11 and the pen input device 12 that are vulnerable to trauma are covered with the housing 2, and only the portion made of reinforced plastic or magnesium alloy is outside. For this reason, measures for protecting the wound of the display device 11 and the pen input device 12 are taken when being carried.
[0042]
Further, the ventilation hole 2c requiring waterproof / dustproof measures is covered with the housing 1. Therefore, measures for waterproofing and dustproofing of the ventilation holes 2c are taken when carrying.
[0043]
In the present embodiment, the gap between the housing 1 and the housing 2 is blocked by the packing 13 provided on the surface of the housing 1 when being carried. As a result, the waterproof and dustproof measures are more reliable.
[0044]
When not in use, the connector 24 a of the external input / output device 24 and the insertion hole 25 a of the PC card slot 25 are blocked by the connecting member 3, and the gap is further blocked by the packing 33. Thereby, waterproof / dustproof measures are taken between the connector 24a of the external input / output device 24 and the insertion hole 25a of the PC card slot 25. Moreover, in the arrangement at the time of carrying, the PC card which is the external storage medium inserted into the PC card slot 25 cannot be removed and the power switch 14 cannot be pressed. Therefore, security is protected by the locking mechanism 4 so that the housing 1 and the housing 2 are not opened in this state.
[0045]
Moreover, since the pen storage part 2d is also covered with the housing | casing 1, the pen for input is not lost when carrying.
[0046]
-Form of use-
FIG. 3B shows an arrangement at the time of use.
[0047]
In use, the outer surface 1e of the housing 1 and the outer surface 2e of the housing 2 and the side surface 2b of the housing 2 and the outer surface 3e of the connecting member 3 are arranged to face each other. That is, the surface 1a of the housing 1, the surface 2a of the housing 2, and the surface 3a of the connecting member 3 are arranged on the outside.
[0048]
In this arrangement, all parts necessary for use are located outside.
[0049]
That is, the display device 11, the pen input device 12, and the input pen housed in the pen housing portion 2d appear outside, so that the pen input type portable data processing device can be used.
[0050]
Further, since the connector 24a of the external input / output device 24 and the insertion hole 25a of the PC card slot 25 appear outside, the external input / output device 24 and the PC card slot 25 can be used.
[0051]
Furthermore, since the ventilation hole 2c also appears on the outside, a countermeasure for heat dissipation of the casing 2 by the forced air cooling device 28 is taken.
[0052]
−In case of failure / performance improvement−
In the event of a failure, repair can be performed by disassembling only the housing containing the failed component. If the hinge is removed, the housing 1 and the housing 2 can be replaced. Therefore, the structure is easier to repair than a conventional pen-input type portable data processing device in which all of the components are housed in one housing.
[0053]
The same applies to the performance improvement.
-Other embodiments-
The embodiment shown in FIG. 4 shows a configuration in which the arithmetic device 21 and the heat sink 22 are housed in another housing 5 other than the housing 1 and the housing 2.
[0054]
Specifically, the arithmetic device 21 is stored inside the housing 5, and the heat sink 22 is exposed outside the housing 5.
[0055]
The housing 2 and the housing 5 are coupled in a state in which the housing 5 is embedded in the housing 2, and in this state, the interconnect device 2 y of the housing 2 and the interconnect device of the housing 5 5y are connected to each other and interfaced with each other.
[0056]
In this case, when the performance is improved, the arithmetic device needs to be replaced. Therefore, the arithmetic device 21 is housed in the housing 5 together with the heat sink 22. As a result, it is easy to replace only the arithmetic device or the entire housing 5. Therefore, not only the repair of the arithmetic device, but also the performance can be easily improved by replacing it with a high-performance arithmetic device.
[0057]
In each of the above-described embodiments, the display device 11 and the pen input device 12 are naturally air-cooled. However, the heat of the housing 1 is brought to the housing 2 through a heat conductor in the hinge, and forced. It is also possible to adopt a method of cooling with the air cooling device 28. Thereby, even when the display device 11 and the pen input device 12 become high temperature, it can be cooled.
[0058]
Further, in each of the above embodiments, the pen input device 12 and the display device 11 are described as examples of the portion vulnerable to the trauma. However, instead of the pen input device 12, for example, an input device using a touch panel or an input using a keyboard Devices are also conceivable. In some cases, such as input by voice input, it is not necessary to take measures to protect the input device from injury, and the display device may be the only part that is vulnerable to injury. Also, depending on the type of data processing device, a display device may not be required, and the input device may be the only part that is vulnerable to trauma. Further, the portion that is vulnerable to trauma may be other than the display device and the input device.
[0059]
Moreover, in each said embodiment, although arrangement | positioning at the time of use and arrangement | positioning at the time of non-use are changed with the hinge mechanism which has 2 axis | shafts via the connection member 3, it is comprised so that it may change with 1 axis | shaft hinge mechanisms. Alternatively, the change may be made after complete separation. In the case of changing after completely separating, the interconnection device 1x of the housing 1 and the interconnection device 2x of the housing 2 are connected at the time of use.
[0060]
Further, the connecting member 3 may also be a member resistant to external damage such as reinforced plastic or magnesium alloy. As a result, the effect of protecting the wound can be obtained.
[0061]
In the above embodiment, each of the housing 1 and the housing 2 is provided with a locking hole so that it can be locked with a padlock. However, the locking mechanism is directly attached to the housing 1 and the housing 2. May be provided. As a key, in addition to a physical key, a dial type, unlocking by entering a password, or the like can be considered.
[0062]
【The invention's effect】
As described above, according to the present invention, the following effects are exhibited.
[0063]
When configured so that the ventilation holes are blocked by other cases when not in use, the waterproof and dustproof effects of the ventilation holes can be demonstrated with a simple structure while carrying while maintaining the heat dissipation effect and usability during use. . As a result, the price is low, and the data processing apparatus can be thinned. Furthermore, since a protective cover is not required, usability is improved.
[0064]
If configured as an insertion hole for the external storage medium is blocked when not in use, also the insertion hole for the external storage medium is water and dust effects can be exhibited with a simple structure. This also makes the price cheaper and allows the data processing apparatus to be made thinner.
[0065]
When it is configured not to be used, even parts that are vulnerable to trauma can be blocked, when it is carried, take measures to protect against trauma and at the same time take waterproof / dustproof measures or security measures. Therefore, it is possible to prevent forgetting to take a waterproof / dustproof measure or a security measure, and a reliable waterproof / dustproof measure or a security measure can be taken. Also, if all holes are closed when not in use, complete waterproof and dustproof measures are taken.
[0066]
When the arrangement at the time of use and the arrangement at the time of non-use can be changed by the hinge mechanism having two axes via the connecting member, a ventilation hole can be provided on the bottom surface.
[0067]
For this reason, it is not necessary to secure a minimum area required for the ventilation hole on the side surface, and the data processing apparatus can be thinned. Moreover, compared with the case where a ventilation hole is provided in a side surface, a large ventilation hole can be provided. Therefore, since the heat dissipation effect is increased, it is possible to cope with higher performance of the arithmetic device.
[0068]
When the arrangement at the time of non-use and that at the time of use cannot be changed, the removal of the external storage medium can be prevented with the effect of not operating the data processing device by a third party. Therefore, the structure is simple compared to the case where a physical key is provided in the insertion hole for the external storage medium, so that security measures can be taken at low cost and the data processing apparatus can be made thin. In addition, security measures can be taken at a lower cost compared to the case where special cards are used. In addition, more secure security measures can be taken if special cards are also used.
