Abstract

(57) [Summary] [Object] An object of the present invention is to improve operability during carrying by providing a small electronic device with a shape that is easy to hold in one hand even when operated as a handheld type. The present invention is achieved by forming at least one convex shape having an optimum shape for one-handed operation on the left side of the case part excluding the operation input part and the display part of a small electronic device. [Effect] A hand-held convex portion is formed on the left side of the tablet plate, which is the operation portion of the main body, and has a convex shape to the outside. Since it is configured as a hook part, the operability is improved without turning the power switch knob on and off, and the operation part and the display part are not covered by the hand during portable operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is, for example, an electronic notebook or a portable terminal (hereinafter referred to as a small electronic device in the present text).
As described above, the present invention relates to a structure for improving the operability in the one that allows the input operation by hand.

[0002]

2. Description of the Related Art In particular, portable electronic devices such as small electronic devices, which have been rapidly popularized in recent years, have an operation input unit and a display unit as disclosed in Japanese Patent Laid-Open No. 324127/1993. Since it is arranged on the entire upper surface of the main body, there is a drawback that the operability is deteriorated because the operation unit and the display unit are covered by the hand during a handheld input operation.

[0003]

In the small-sized electronic device of the conventional type described above, since the operation input section and the display section are provided over the entire upper surface of the main body as described above, when inputting as a handheld type while carrying, the display section or There is a problem that it is difficult to operate because the operation part is covered with hands.

An object of the present invention is to improve the operability when carrying a portable electronic equipment by making it easy to hold in one hand even when it is operated as a handheld type.

[0005]

The object is to construct at least one convex shape on the left side of the case excluding the operation input section and the display section of a small electronic device, which has an optimum shape for one-handed operation. It is achieved by

[0006]

[Function] Usually, this kind of small electronic device is often used as a handheld type by pen input or key input. Generally, as a handheld type, hold it in your left hand, open the cover, and then turn on the power switch to input the pen. , Start key input operation.

During these operations, in addition to the weight of the small electronic device itself, a force is applied during operation. Therefore, by forming an ergonomically shaped handle part on the left side of the operation part and the display part. Even when it is used as a hand-held type, it is less likely to get tired, and the operation unit and the display unit are not covered by the hand, and the operability when carried is improved.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a small electronic device according to an embodiment of the present invention, FIG. 2 is a usage state diagram when it is used as a hand-held type, FIG. 3 is a detailed view of essential parts, and FIG. 4 is a schematic internal view. It is sectional drawing which shows a structure.

Reference numeral 1 denotes an operation unit provided with a tablet plate or the like, which is operated by a pen 2 from the surface of the tablet plate 1. The operation status and input information of the tablet board 1 are displayed on the liquid crystal display device 3 arranged below the tablet board 1. Reference numeral 4 is an upper case that covers the tablet plate 1 and the liquid crystal display device 3, and 5 is a lower case, and a cover 6 that protects the tablet plate 1 when being carried is provided on the entire surface.

The cover 6 and the main body 7 are connected by a hinge mechanism 7 which can be rotated 360 ° so that they can be set on the back side of the lower case 5 of the main body 8.

Reference numeral 9 denotes an engaging claw provided on the cover, which is engaged with the fitting hole 10 of the upper case 4 when the cover is closed, and the push button 11 disengages the cover 6 to remove the cover 6. It is configured to open. 12 is a liquid crystal display device 3
The contrast volume for adjusting the display screen of the device, 13 is a speaker for transmitting in accordance with the operation function, 14 is a card slot into which various cards such as a memory card and a communication card are inserted, and 15 is an eject button for card removal. . Reference numeral 16 is a control board for controlling the entire apparatus.

On the other hand, on the left side of the operating portion such as the tablet plate 1 is formed a hand-held convex portion 17 having an outward convex shape in consideration of ergonomics. The hand-held convex portion 17 is composed of a first convex portion 18 and a second convex portion 19, and the first convex portion 18 and the power switch knob 2 which are ordinary hand-held convex portions.
The boundary portion 21 of the second convex portion 19 where 0 and the like are arranged is substantially the main body 8
It is formed so as to be located behind the center of the.
That is, it is for ergonomically optimizing the shape, size, etc. of the first convex portion 18 on which the palm is applied. Therefore, the second convex portions 19 on the rear side other than the first convex portion 18 are for forming the boundary portion 21 with the first convex portion 18, and have a configuration which is also valid even in the straight shape. On the contrary, even if a plurality of them are formed, the boundary portion 21 is formed and the same holds.

With this structure, the first convex portion 18 is used as a hand-held convex portion, and the operation portion such as the power switch knob 20 is arranged near the second convex portion 19 to turn on the power. It allows one-handed operation from OFF to operation.

[0015]

According to the present invention, the outwardly convex hand-held convex portion provided on the left side of the tablet plate, which is the operation portion of the main body, is formed. Since the boundary between the parts is designed to be a part to be hooked with a finger, the power switch knob is turned on and off during portable operation.
In addition, the operability is improved without the operation unit and the display unit being covered by the hands.
