1. A medical system comprising:
- a capsule type medical device having a capsule configuration;
an operation device, arranged external to the capsule type medical device, and including a binary signal generator for generating a binary signal having a particular pattern;
a switch, arranged in the capsule type medical device, for switching on and off power of the capsule type medical device;
a switch driver circuit for controlling the switch for a power on operation or a power off operation, the switch driver circuit being operative in response to the binary signal;
a sensor, arranged in the capsule type medical device, which directly detects a binary signal applied from the outside and is used for the power on or off; and
a pattern monitoring unit, arranged in the capsule type medical device, for monitoring whether or not the particular pattern is included in an output signal from the sensor;
wherein in a state where the power of the capsule type medical device is off the switch is turned from an off state to an on state when the pattern monitoring unit detects the binary signal from an output signal of the sensor, the switch is turned to the on state long enough for the pattern monitoring unit to determine if the particular pattern is included in the binary signal, the switch is kept in the on state if the pattern monitoring unit determines that the particular pattern is included in the binary signal, and the switch is turned to the off state if the pattern monitoring unit determines that the particular pattern is not included in the binary signal.
