2. Description of the Related Art Conventionally, a female electronic thermometer provided with data processing means, time setting means for setting time for measuring body temperature, and notification means for notifying when the time set in the time setting means is timed (Patent Document 1: Japanese Patent Laid-Open No. 10-239164) Gazette), a time setting means for setting a measurement time, and an electronic sphygmomanometer having a measurement type setting means for setting whether to perform a blood pressure measurement at the set time or to perform automatic blood pressure measurement (Patent Document 2 : JP-A-2001-70260) and the like have been proposed. These women's thermometers have an internal clock and store date information and body temperature values counted by the internal clock in pairs in the EEPROM.
JP-A-10-239164 JP 2001-70260 A

The internal clock always starts from the initial value (for example, 0:00 on January 1, 2005) when the battery is inserted, so if you change the battery, the date will be updated for several days. Must match the date and time of the month.

Since this is very troublesome, the current date is saved in the EEPROM every hour (every 00 minutes), and when the battery is inserted, the current date is read from the EEPROM and start from there. I was doing. For example, if the battery is removed at 16:30 on December 15, 2005 and replaced at 17:30 on December 15, 2005, it will not be corrected from 0:00 on January 1, 2005. Since it will be corrected from 16:00 on December 15, 2005, the labor is simplified.

On the other hand, the data stored in the EEPROM is checked to see if the value read from the EEPROM is correct by performing a sum check, writing the same data in three locations, and performing majority logic to increase reliability. It is usual to provide a means for confirming. As a case in which the data stored in the EEPROM is destroyed, the battery may be removed during writing. The sum value is stored. If a sum check error occurs, a method of displaying the error as a failure and making it unusable can be considered, but the failure is very inconvenient for the customer. Alternatively, if a sum check error occurs, the current year / month / date may be set to the initial value (January 1, 2005, 0:00) and operated. When used without being aware, there was a problem that the time series of the data sequence in which the date and body temperature were stored in pairs would be incorrect.

The present invention has been made in view of the above problems, and even when the date and time information read from the nonvolatile memory is inappropriate, the biometric information such as the body temperature value, the blood pressure value, and the blood sugar level can be correctly obtained by continuing with the correct date and time. An object of the present invention is to provide a biological information measuring device that can be stored in time series.
