Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device suitable for moving and carrying.

[0002]

2. Description of the Related Art First, FIG. 15 and FIG.
This will be described with reference to FIG. 15 is a perspective view and FIG.
Is a vertical sectional view.

In FIGS. 15 and 16, reference numeral 1 denotes an electronic device such as a personal computer, which is a main body 2 when not in use.
By closing the lid portion 3 pivotally supported above, a cuboid-shaped casing 4 having a portable size is formed. When the lid 3 of the housing 4 is opened like a book during operation, the display 5 on the surface of the lid 3 and the keyboard 6 of the input device provided on the upper portion of the main body are deformed to be exposed. Reference numeral 7 is a mouse of an auxiliary input device used by connecting to the main body 2 with a cable.

Inside the main body 2, a semiconductor device 8 and a substrate 9 on which circuit components (not shown) are mounted are housed, and at the same time, a space 10 is formed inside.

Further, since the above-mentioned structure is adopted, the book is opened as shown in the figure at the time of operation, and the posture is unstable. Therefore, when used for a long time, a desk or the like is generally relatively flat. It is used by placing it on a surface. Further, for example, when the user performs an operation while holding the electronic device 1 while standing, the user holds the housing 4 with one hand and the other with the keyboard 6 as the input device. The user must operate the keyboard 6 to input.

For this reason, when the user holds the housing 4 in a standing posture, the input is made with one hand, so that it is difficult to use it efficiently. On the other hand, when trying to use it efficiently, the usage state is limited.

When used, the semiconductor device 8 mounted on the substrate 9 operates to generate heat, and the heat is generated by the main body 2 of the housing 4.
From the surface of the device due to natural convection, or escape to a desk or the like on which the electronic device 1 is placed. However, in a small and highly functionalized product, since the mounting density of the main body 2 is high and the free space is small, almost no natural convection is generated inside the main body 2 due to heat conduction of the circuit components and the air inside the main body 2. The heat generated in the semiconductor device 8 is transferred to the surface of the main body 2. The thermal conductivity of air is extremely low, and the resistance against heat transfer inside the casing becomes large as compared with the case where convection occurs, and there is a problem that it is difficult to cool the semiconductor device 8.

Next, the second conventional technique will be described with reference to FIG. FIG. 17 is a perspective view, and in FIG.
Reference numeral 1 denotes an electronic device such as a mobile phone, a small mobile radio device, etc., in which a lower housing 13 having a microphone 12 and an upper housing 15 having a speaker 14 are rotatably connected by a hinge 16. . As a result, the hinge 16
Allows the lower case 13 and the upper case 15 to be opened, and when not in use, the electronic device 11 can be folded by a hinge 16 to be stored and carried in about half the size. There is. The lower housing 13 and the upper housing 15 are made of a material having a relatively high modulus of longitudinal elasticity (for example, plastic), 17 is an operation button, and 18 is a display unit.

In consideration of the convenience of use as a telephone, the microphone 12 is located near the user's mouth and the speaker 14 is located near the ear during use, and the lower part of the housing is used. The length of 13 and the upper part 15 of the housing are each about 70 mm. That is, the folded form is a hard rod-like member having a length of about 70 mm.

For this reason, the folded electronic device 11 is likely to be subjected to a force that greatly deforms when it is carried, and if there is a case where the folded electronic device 11 receives a force and is greatly deformed, the lower casing 13 and the upper casing can be easily mounted. There was a possibility that it might lead to the damage of 15. For example, when folded and carried in a trouser pocket, a state in which a large deformation force is generated each time the wearer changes his / her posture, and the lower casing 13 and the upper casing 1
There is a problem that 5 is likely to be damaged.

Next, the third conventional technique will be described with reference to FIGS.
Will be described with reference to. 18 is a perspective view, FIG. 19 is a diagram for explaining the flow of traffic information, and FIG. 20 is a diagram for explaining the flow of weather information.

18 to 20, reference numeral 21 denotes an electronic device such as a mobile phone or a small mobile radio, which is a housing 2
2, a display 23, operation buttons 24, a microphone 25,
A speaker 26 is attached and an antenna 27 for transmission and reception
Used for communication between remote areas. The basic function is, for example, for exchanging information by inputting / outputting voice when operating as a mobile phone, and the display 23 is used only for displaying the telephone number input by the operation button 24.

Therefore, the above-mentioned configuration has a problem that it is not suitable for communication of information that needs to be displayed by graphics other than voice.

On the other hand, as shown in FIG. 19, traffic information such as traffic congestion is collected by a sensor group installed mainly at a predetermined organization such as a road administrator, and the collected information is integrated at a processing center. It Then, it is transmitted to each individual who wants to use the traffic information through a general information transmission medium such as a television or a radio. Further, when using the traffic information, a navigation system that displays the current position from the received radio waves from the artificial satellite and the carried map information may be used together.

However, since the infrastructure such as a sensor group that can be prepared by one institution is limited and the information provided is coarse, it has not been possible to sufficiently meet the individual requirements of users.

Further, as for the weather information, as shown in FIG. 20, the information about the weather conditions from each region and point is collected from the sensors arranged in the processing center to be integrated into each processing individual. Is transmitted through general information transmission media such as television and radio.

For this reason, the weather information, as well as the traffic information, is not provided sufficiently because the information provided is coarse.

Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment of the first invention will be described with reference to FIGS. 1 to 4. 1 is a perspective view,
2 is a perspective view seen from the back side, FIG. 3 is a longitudinal sectional view, and FIG. 4 is a characteristic diagram showing an output with respect to the pressure of the input pad.

In FIGS. 1 to 4, reference numeral 31 denotes a personal computer or an electronic device such as a mobile terminal device thereof, which has a flat device shape and is framed by a device frame 32 serving as a device housing. Further, a display 35, which is a display device having substantially the same size, and an input pad 36, which is an input device, are provided so as to be exposed on the two surfaces 33, 34 that face each other and that face each other.

A semiconductor device 37, such as an LSI, which constitutes an electronic circuit, and a substrate 38, on which circuit components (not shown) and the like are mounted, are provided between the two opposing surfaces 33 and 34. The substrate 38, together with the device frame 32 whose periphery is fixed, constitutes a strength holding member for the electronic device 31. Although not shown, the battery for driving the electronic device 31 is also a device frame 32.
It is designed to be built into.

Further, the electronic device 31 has two facing surfaces 3
A molding material 39 such as silicone rubber or epoxy resin is filled between the spaces 3 and 34 to be sealed. In addition, 40 is a spacing member mounted between the opposing two surfaces 33 and 34 and the substrate 38, 41 is a microphone for performing voice input, and 42 is for performing input check and output by sound. Reference numeral 43 is a speaker, and 43 is an optical connector for exchanging signals with an external device or the like.

The plate-shaped input pad 36 can sense the distribution of the applied pressure.
A user can apply desired pressure to the electronic device 31 by applying pressure to the device 6 with a finger of the hand H or the like. That is, the built-in software causes the display corresponding to the input content to be displayed on the display 35, and the input pad 3
By pressing a predetermined key portion, which is positioned by software or hardware, on the back side of the pseudo keyboard 6, the corresponding character portion of the pseudo keyboard 44 displayed on the display 35 is displayed as a mark M, for example, dark color. For example, the character displayed with the mark M or the like is input while it can be discriminated from other parts by becoming blunt or blinking.

Similarly, the built-in software switches to handwriting input and traces a predetermined portion on the input pad 36 with a finger, so that, for example, a character is input by handwriting on the display 35 according to the locus traced by the finger. Part 4
It is shown in FIG. 5, and the input can be done.

Further, the sealing with the molding material 39 improves the reliability against vibration and shock. The molding material 39 may contain particles of a material having a high thermal conductivity such as aluminum nitride or alumina.

Although the input pad 36 is configured to perform two-step recognition of "pressure is applied / not applied", the horizontal axis shown in FIG. 4 is pressure and the vertical axis is vertical axis. As shown in the characteristic diagram obtained from the output, the input pad 36 can recognize at least three stages of pressures of "no pressure is applied, weak pressure is applied, and strong pressure is applied". You may do it. According to this, for example, the cursor 46 is displayed on the display 35 corresponding to the position where the input pad 36 is lightly touched, and it is possible to instruct the operation of the software by strongly pressing. That is, since the magnitude of the pressure applied to the input pad 36 can correspond to the conventional movement of the mouse and the click of the button, the conventional software assets can be inherited.
