In addition, since the power required for the creation is provided by the battery pack 14, the use of electrical energy must of course be saved as much as possible. Since the creation starts from weighing to display data and reading, it takes only a few seconds. In order to prevent the user from forgetting to use the open/close switch 12a to turn off the power supplied by the battery pack 14 and waste it, the creation is wasteful. The control circuit 11 is designed with an automatic power-off circuit. When the creation does not accept any operation command for a period of time, and the central processing unit 16 does not receive any new weight data, the automatic power-off circuit will automatically interrupt. All of the electrical energy provided by the battery pack 14 is used to save energy and extend the life of the battery pack 14 of the present invention.
