If a message indicated by the notification signal is displayed on the small monitor 33, the user can check the message and confirm that the bioinformation output device 30 cannot be driven for the specified time RT or more, i.e., 12 hours or more, in the current drive. After that, the control unit 60 performs a termination process, and the drive of the bioinformation output device 30 is stopped before the current drive of the bioinformation output device 30 proceeds.
  • the CPU 61 executes a notification process.
  • the CPU 61 outputs a notification signal.
  • the notification signal is a signal that notifies the user that the bioinformation output device 30 cannot be driven for the specified time RT. Therefore, the user can confirm from the notification signal that the driven bioinformation output device 30 cannot be driven for the specified time RT or more. Therefore, it is possible to prevent the bioinformation output device 30 from stopping unexpectedly within the specified time RT.
  • the CPU 61 further executes the termination process after performing the notification process. Therefore, in the current operation of the bioinformation output device 30, it is possible to prevent the operation of the bioinformation output device 30 from suddenly stopping due to the battery running out during the specified RT operation. In other words, if an unexpected stop occurs during the specified RT operation, the operation of the bioinformation output device 30 can be stopped at the start. Furthermore, since the CPU 61 executes the termination process after performing the notification process, the bioinformation output device 30 can stop operation in a state that the user can expect.
  • the CPU 61 executes a warning process.
  • the CPU 61 outputs a warning signal.
  • the warning signal is a signal that notifies the user that the current remaining amount CL is almost complete. Therefore, the user can confirm from the warning signal that the bioinformation output device 30 can only be operated for a short time. This makes it possible to prevent the bioinformation output device 30 from entering a state that is unexpected by the user after the warning process.
  • the CPU 61 executes the termination process after the warning process. Therefore, the bioinformation output device 30 can stop operating in a state that the user can expect.

Therefore, the bioinformation output device 30 can be driven continuously for a longer period of time. In other words, it is possible to avoid the bioinformation output device 30 from stopping its drive unnecessarily.
  • the CPU 61 executes a warning process when the continuous drive time CT becomes equal to or greater than the specified time RT.
  • the CPU 61 outputs a warning signal.

Therefore, the user can confirm from the warning signal that the drive time of the specified time RT, which is guaranteed by the absence of the notification process, has passed. This makes it possible to prevent the bioinformation output device 30 from entering a state that the user does not expect after the warning process.
  • the CPU 61 further executes the termination process after the warning process. Therefore, the bioinformation output device 30 can stop operating in a state that the user can expect.

  • the CPU 61 executes a first connection process.
  • the CPU 61 establishes wireless communication only with the biosensor 20 stored in the storage device 64 as a communication destination.

  • the CPU 61 executes a storage process when the continuous drive time CT is equal to or greater than the specified time RT.
  • the CPU 61 stores the communication destination in the storage device 64. Therefore, even if the termination process is performed after the continuous drive time CT is equal to or greater than the specified time RT, the storage device 64 will have stored the communication destination at the next startup. Therefore, at the next drive, wireless communication can be established with the same communication destination.
  • the CPU 61 executes the second connection process.
  • the CPU 61 allows the establishment of wireless communication with a biosensor 20 that is not stored as a communication destination in the storage device 64. Therefore, even when the storage device 64 does not store a communication destination, wireless communication can be established and bioinformation can be acquired.
  • the bioinformation output device 30 is powered on when the switch 34 is operated.
