Abstract

PROBLEM TO BE SOLVED: To prevent an operator from feeling the device heavy as it is and improve the operability by setting the mount position of a battery so that the center of gravity of the device is at an operator's grip position. SOLUTION: An upper cover 1 and a lower cover 2 are engaged and a display part 3 and an input part 4 are arranged on the surface of the device, i.e., the upper cover 1. A circuit board 5 is provided with a electric feeding pad 6 and comes into contact with a positive electrode 7 and a negative electrode 8. The circuit board 5 is held between the upper cover 1 and the lower cover 2. The battery 9 is arranged on the side of the lower cover 2 almost in the center of the device so that the center 0 of gravity of the device is at the operator's grip position. Then when the device is held in the hands, both the surface sides and bottom surface are held and at this time, the battery 9 is arranged inside the lower cover 2 in contact with the palm of the hand, so its weight is applied to the palm of the operator through the lower cover 2, thereby improving the operability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable electronic device using a battery as a main power source.

[0002]

2. Description of the Related Art FIG. 3 is a sectional view showing a conventional example of this type of portable electronic device, and FIG. 4 is a perspective view of the same. An input unit 4 and a display unit 3 are provided on the surface of the device. Upper cover 1
A circuit board 5 is sandwiched between the lower cover 2 and
A power supply pad 6 is provided at one end. The battery 9 is disposed further outside the power supply pad 6, and the positive electrode 7,
Electrical connection is made to the power supply pad 6 of the circuit board 5 through the negative electrode 8.

When an operator operates this apparatus, the user has to hold both sides and the bottom of the input unit 4 slightly closer to the display unit by hand as shown in the figure.

[0004]

However, according to the prior art having the above structure, since the battery is located at a position distant from the position where the operator holds the device, as shown in FIG.
However, there has been a problem that the operability is poor, such as detachment from the palm, the device being felt heavier than the actual weight, and tired hands.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to improve the operability by obtaining a configuration for preventing the operator from feeling the device as heavy as the actual weight.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention makes the center of gravity of the device rest on the palm of the operator. That is, the present invention is characterized in that, in a portable electronic device using a battery as a main power source, the mounting position of the battery is set such that the center of gravity of the device is located at an operator gripping position.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a perspective view of the same. In the drawing, 1 is an upper cover, 2 is a lower cover, and the appearance of the apparatus is formed by fitting the upper cover 1 and the lower cover 2 together.
A display unit 3 and an input unit 4 are provided on the surface of the apparatus, that is, on the upper cover 1. Reference numeral 5 denotes a circuit board. The circuit board 5 is provided with a power supply pad 6 and has a structure in contact with a positive electrode 7 and a negative electrode 8. The circuit board 5 is sandwiched between the upper cover 1 and the lower cover 2.

Reference numeral 9 denotes a battery. The battery 9 is disposed substantially at the center of the lower cover 2 so that the center of gravity O of the device is present at the position where the operator grips the device. The operation of the present embodiment having the above configuration is as follows. When the user holds the apparatus in his / her hand, the user generally has both sides and a bottom of the input unit 4 slightly closer to the display unit 3 as shown in the figure. At this time, since the battery 9 is disposed inside the lower cover 2 which is in contact with the palm, all of the weight is applied to the palm of the operator through the lower cover 2.

[0009]

According to the present invention having the above-described structure, in a portable electronic device using a battery as a main power source, the mounting position of the battery is set so that the center of gravity of the device exists at the position where the operator grips the device. Therefore, the center of gravity of the device can be applied to the palm of the operator. This has the effect that the operator does not feel the device as heavy as the actual weight, and the operability is improved.
