[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopwatch device.

[0002]

2. Description of the Related Art Conventionally, in a stopwatch device, for example, the time required for traveling a certain distance, that is, the traveling time, is measured and stored, and later read out and displayed to determine whether the current traveling time is good. What is available for practical use is that it is possible to evaluate whether it is bad, or how many times it is compared with the recent running time already stored.

[0003]

Incidentally, the above-mentioned running time and the like largely depend on environmental conditions such as climate. Therefore, comparison of running times and the like under different environments is often meaningless. Therefore, a method is also conceivable in which the travel time and the like and the date and time of the measurement are stored together, and the climate and weather at that date and time are checked later, and the travel time and the like are evaluated in consideration of the climate and weather. But the past climate
It is not so easy to check the weather and the like each time. The present invention has been made in view of the above-described circumstances, and examines the environmental state at that date and time in order to evaluate stored time data such as running time in consideration of the environmental state at the date and time of the measurement. An object of the present invention is to provide a stopwatch device that eliminates bothersomeness.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a sensor for detecting an environmental condition, and time data measured separately for a plurality of groups according to the detected environmental condition. When reading these, when a specific one of the above groups is designated,
Only the time data belonging to this is displayed on the display unit.

May be different.

[0029]

According to the present invention, as described in detail above, a sensor for detecting an environmental state is provided, and time data measured separately for a plurality of groups according to the detected environmental state is stored. When a specific one of the above-mentioned groups is designated at the time of reading, since the present invention relates to a stopwatch device in which only the time data belonging to this is displayed on the display unit, the stored time such as the running time is stored. In order to evaluate data in consideration of the environmental state at the date and time of the measurement, it is possible to provide a stopwatch device that eliminates the trouble of checking the environmental state at the date and time.
