Portable electronic equipment and control method of the same

Abstract

An operator, such as a user, can force an electronic device into a power save mode at the operator's own discretion by manipulating a control. Electrical energy stored is thus reliably saved in accordance with the usage by the operator, and power consumed in vain is more efficiently reduced than in a method in which a device automatically stops a time displaying and is shifted into a power save mode in accordance with the presence or absence of power generation. With the time limit within which the operational state of the control needs to be complete, the operator is free from an erroneous shift into the power save mode, and the ease of use of the time measurement device is still assured.

Description

technical field [0001] The invention relates to a portable electronic device and a control method of the portable electronic device, in particular to a technology for reducing power consumption of an electronically controlled timer with an analog pointer. Background technique [0002] In recent years, a small watch-type electronic timepiece has been developed that incorporates a power generating device such as a solar cell and operates without replacing the battery. In this type of electronic timepiece, it has the function of charging a large-capacity capacitor with the power generated by the power generating device at one time, and can display the time by using the power discharged from the capacitor when the power is not generated. Therefore, it can operate stably for a long time without installing a battery. Therefore, considering the time required for battery replacement and the problem of battery disposal, it is expected that more electronic timepieces will be equipped ...

AI Technical Summary

Problems solved by technology

[0006] However, it is also necessary to check the time frequently at night, but at this time, the current time cannot be immediately known, so it is very inconvenient

In addition, in winter when wearing a coat, etc., the watch is not exposed to light in most cases, and in this case, if the time is stopped, it loses its role as a watch

On the contrary, when the watch is not worn but placed indoors, etc., timekeeping can only be performed under weak irradiating light, which will cause unnecessary power consumption

[0007] In addition, the transfer from the normal operation mode to the power-saving mode is judged by the control device in the watch-type timekeeping device, and the user cannot transfer to the power-saving mode according to his own wishes. The problem of reducing power consumption may not be achieved in the corresponding optimal state

Or, in the process of assembly, inspection, packaging in the factory, transportation and storage from the factory to the retailer, there is also a problem that it cannot be freely shifted to the power saving mode, and thus the power consumption cannot be reduced.
