2 . The endoscope system according to claim 1 , wherein the controller is further configured to:

determine whether the information indicating use of the endoscope is recorded in a memory,

permit operation of the endoscope when the information is not recorded, and

prevent operation of the endoscope when the information is recorded.

3 . The endoscope system according to claim 1 , further comprising:

a memory configured to store the detection result.

4 . The endoscope system according to claim 3 , wherein the memory is located in the endoscope.

5 . The endoscope system according to claim 3 , wherein the controller is configured to record information indicating use of the endoscope based on the detection result received in the memory when the detection result is received twice.

6 . The endoscope system according to claim 1 , wherein, prior to recording of information, the endoscope is configured not to supply power to the image pickup apparatus, and

wherein, after recording of information, the endoscope is configured to supply power to the image pickup apparatus.

7 . The endoscope system according to claim 6 , further comprising a processor configured to connect to the endoscope,

wherein the processor includes the controller, and

wherein the controller is configured to:

analyze the generated image as the detection result; and

generate the information based on the analyzed generated image.

8 . The endoscope system according to claim 1 , wherein the access instrument includes a magnetic material configured to generate a magnetic field,

wherein the sensor includes a coil, and

wherein the detection result is an electric current in the coil occurring when the magnetic material moves relative to the coil during inserting of the insertion section into the access instrument.

9 . The endoscope system according to claim 1 , wherein the access instrument includes a first antenna configured to transmit a radio wave or a magnetic field,

wherein the sensor includes a second antenna, and

wherein the detection result is the radio wave or the magnetic field transmitted by the first antenna during inserting of the insertion section into the access instrument.

10 . The endoscope system according to claim 1 , further comprising an illumination apparatus configured to radiate light from the insertion section,

wherein the detection result is the light radiated by the illumination apparatus during inserting of the insertion section into the access instrument.

11 . The endoscope system according to claim 10 , wherein the authentication code is configured to reflect the light radiated by the illumination apparatus, and

wherein the optical sensor is configured to detect the reflected light.

12 . The endoscope system according to claim 10 , wherein the authentication code is configured to absorb the light radiated by the illumination apparatus, and

wherein the optical sensor is configured to detect the reflected light from an area adjacent to the authentication code.

13 . The endoscope system according to claim 1 , further comprising:

a suction apparatus;

a suction channel connected to the suction apparatus and configured to suction gas; and

an odor sensor configured to detect an odor level as the detection result,

wherein the controller is configured to calculate a second detection result based on the detected odor level and a predetermined threshold.

14 . The endoscope system according to claim 1 , wherein the controller is configured to:

count time after receiving the detection result, and

record information indicating use of the endoscope when the counted time is larger than a predetermined time.

15 . The endoscope according to claim 1 , wherein the authentication code is selected from the group consisting of a barcode, a two-dimensional barcode, a pattern and a color.

16 . An endoscope, comprising:

an insertion section insertable into a subject;

an optical sensor configured to detect a detection result relating to insertion of the insertion section into the subject;

a memory; and

a controller configured to:

receive the detected detection result; and

record information indicating the detected detection result in the memory,

wherein the insertion section includes an image pickup apparatus configured to generate an image and the optical sensor, the optical sensor being arranged at a position of 20 cm or more from a distal end face of the insertion section toward a proximal end side, and the optical sensor configured to detect an authentication code included with an access instrument configured to guide the insertion section, and

wherein detecting the detection result includes the optical sensor detecting the authentication code.

17 . The endoscope according to claim 16 , wherein the controller is further configured to:

determine whether the information concerning the detected detection result is recorded in the memory,

permit operation of the endoscope when the information is not recorded, and

prevent operation of the endoscope when the information is recorded.

18 . The endoscope according to claim 16 , wherein the authentication code is selected from the group consisting of a barcode, a two-dimensional barcode, a pattern and a color.
