1. A digestive organ endoscope system comprising:
an endoscope instrument that is configured to be inserted into a digestive organ of a patient and observes or treats an inside of the digestive organ;
an endoscope channel portion in which a channel through which the endoscope instrument moves is formed; and
a sensing portion that informs a user whether or not a tip of the endoscope instrument approaches a tip of the endoscope channel portion at a set distance or less,
wherein the sensing portion includes a plurality of tags that generate magnetism, wherein each of the plurality of tags is formed at a position corresponding to an inlet of the channel of the endoscope channel portion when the tip of the endoscope instrument is at positions of a first predetermined distance, a second predetermined distance, a third predetermined distance, a fourth predetermined distance, and a fifth predetermined distance before reaching the tip of the endoscope channel,
wherein the plurality of tags are formed by gradually reducing intervals therebetween in inverse proportion to a reaching distance,
wherein a detector generates an alarm sound corresponding to the reaching distance as the tip of the endoscope instrument approaches to the tip of the endoscope channel portion at a set distance.
