Embodiment 1

[0027] (1) Structure of Embodiment 1

[0028] figure 1 It is a perspective view showing the electronic camera of the portable electronic device according to the first embodiment of the present invention. The electronic camera 1 is formed in a thin, horizontally long rectangular shape. Viewed from the front side, electronic camera 1 is provided with lens 2 at its horizontally long end side, and at the upper end side, is provided with viewfinder window 3, flashlight 4, near lens 2, is provided with microphone 5, Selfie light 6 roughly in the center. As a result, the electronic camera 1 is formed as a substantially rectangular flat member from the center of the front side, except for the left side and the upper end side. The electronic camera 1 is also provided with a shutter button 7 and a power switch 8 on the upper end surface, and a liquid crystal screen, various operation keys, etc. on the back side.

[0029] In this way, the electronic camera 1 is externally formed by a ...

Embodiment 2

[0055] Image 6 It is a connection diagram showing both capacitors and corresponding circuit blocks used in the electronic camera according to Embodiment 2 of the present invention. In this electronic camera, a battery 11 is installed in the same manner as in the above-mentioned first embodiment, and the capacitor 13 of the battery 11 is used for Image 6 circuit block shown. Furthermore, the electronic camera of this embodiment is not only compatible with Image 6 Except for the difference in the structure, it has the same structure as the electronic camera of the first embodiment.

[0056] That is, in this electronic camera, the DC-DC converter 48 mounted on the wiring board 32 boosts the power of the battery 11 to generate power of a required voltage, and the capacitor 13 is used for smoothing the power.

[0057] Even in the case where a large-capacity capacitor for smoothing is provided as in the present embodiment, the same effect as that of the first embodiment can be...

Embodiment 3

[0059] Figure 7 It is a connection diagram showing both the battery and the corresponding circuit block used in the electronic camera according to Embodiment 3 of the present invention. In this electronic camera, a battery 11 is installed in the same manner as in the above-mentioned first embodiment, and the capacitor 13 of the battery 11 is used for Figure 7 circuit block shown. Furthermore, the electronic camera of this embodiment is not only compatible with Figure 7 Except for the difference in the structure, it has the same structure as the electronic camera of the first embodiment.

[0060] That is, in this electronic camera, the capacitor 13 is used for decoupling the power supply of the battery 11 input to the wiring board 32, and the drop of the power supply voltage caused by the instantaneous current is alleviated.

[0061] As in the present embodiment, the same effect as that of the first embodiment can be obtained even when the drop in the power supply voltage...

Abstract

PROBLEM TO BE SOLVED: To thin an electronic apparatus even when installing a large-capacitance capacitor by applying it to, for instance, an electronic still camera, a cellular phone, a PDA or the like, in relation to an electronic apparatus, a capacitor and a mounting method of a capacitor in an electronic apparatus.SOLUTION: The capacitor is formed with a flat shape by alternately stacking electrodes for a positive electrode and electrodes for a negative electrode, and the capacitor is installed on the side of a battery 11 so as to face it to an electronic apparatus.

Description

technical field [0001] The present invention relates to batteries, electronic devices, and methods for installing capacitors in electronic devices, and can be applied to, for example, electronic cameras, mobile phones, PDAs (Personal Digital Assistants; personal digital assistants) and the like. In the present invention, a capacitor is formed in a plate shape by alternately stacking anode electrodes and cathode electrodes, and the capacitor is placed on the battery side so as to face the electronic device, so that even when a large-capacity capacitor is provided, it is possible to Thinning electronic devices. Background technique [0002] Conventionally, portable electronic devices such as electronic cameras have been thinned in order to improve portability. Therefore, also for electronic components provided in mounting, thin electronic components are employed. However, in the case of an electrolytic capacitor of a bulk capacitor, it is thicker than other parts. Therefore...
