  When the insertion portion attaching / detaching switch 3g is not depressed, the protruding portion 3i protrudes by an amount, for example, as shown in FIG. 5, which can be engaged with the hook portion 2k of the rubber member 2i. Further, when the insertion portion attaching / detaching switch 3g is pressed, the protruding portion 3i protrudes by an amount, for example, as shown in FIG. 6 so that the hook portion 2k of the rubber member 2i can be inserted and removed.

  The plurality of terminal holes 3j are connected to each part of the rotating device 3 by a signal line (not shown) and to the signal cable 3a via each part.

  Next, the operation of the endoscope system 1 will be described.

  First, after the user turns on the power of each part of the endoscope system 1, the user connects the insertion part 2 having the first identification information and the rotating device 3 (step S1 in FIG. 11).

  Specifically, the user pushes the connector portion 2a into the inner back side of the holding portion 3f while pressing the insertion portion attaching / detaching switch 3g while changing the holding portion 3f to the state shown in FIG. Thereby, the support member 2j pressed against the convex portion 3h is broken, and the hook portion 2k is disposed on the inner back side of the holding portion 3f.

  Then, the user stops pressing the insertion portion attaching / detaching switch 3g in a state where the hook portion 2k is disposed on the inner back side of the holding portion 3f. Accordingly, the connector 2a of the insertion portion 2 and the holding portion 3f of the rotating device 3 are configured such that the plurality of connection terminals 2g are inserted into the plurality of terminal holes 3j and the hook portion 2k is engaged with the protruding portion 3i. As shown in FIG. 7, the connection is made.

  When the insertion unit 2 and the rotation device 3 are connected, the identification information storage unit 2f outputs the first identification information that is unique to the insertion unit 2 to the connection detection unit 3d of the rotation device 3. . When the first identification information is input, the connection detection unit 3d detects that the insertion unit 2 and the rotating device 3 are connected, and the first identification information is transmitted to the video processor 5 and The data is output to an external device such as a filing device (not shown) existing on the network. The first identification information output from the rotation device 3 is stored in the identification information determination unit 5d of the video processor 5 and the external device (step S2 in FIG. 11).

  Thereafter, the user finishes observing the subject as the observation target, and removes the insertion unit 2 having the first identification information from the rotating device 3 (step S3 in FIG. 11).

  Specifically, the user pulls out the connector part 2a from the inner back side of the holding part 3f while pressing the insertion part attaching / detaching switch 3g to bring the holding part 3f into the state shown in FIG.

  When the connector portion 2a is completely removed from the holding portion 3f, the support member 2j is broken, so that the rubber member 2i contracts toward the center of the connector portion 2a. Then, as the rubber member 2i contracts, as shown in FIG. 8, the hook portion 2k becomes unable to engage with the protruding portion 3i, and the openings present in the insertion direction of the plurality of connection terminals 2g are present. It becomes a blocked state.

  The state when the connector portion 2a shown in FIG. 8 is viewed from the direction of the arrow A2 (from the rubber member 2i side) is as shown in FIG.

  On the other hand, in order to perform another observation, the user connects the insertion unit 2 having the second identification information and the rotation device 3 by a method substantially similar to the method described above in the description of step S1 in FIG. (Step S4 in FIG. 11).

  When the insertion unit 2 and the rotation device 3 are connected, the identification information storage unit 2f outputs second identification information, which is identification information unique to the insertion unit 2, to the connection detection unit 3d of the rotation device 3. . When the second identification information is input, the connection detection unit 3d detects that the insertion unit 2 and the rotation device 3 are connected, and uses the second identification information as the video processor 5 and The data is output to an external device such as a filing device (not shown) existing on the network.

  The identification information determination unit 5d of the video processor 5 and the external device refer to the existing identification information including the first identification information stored in each, and rotate in step S4 of FIG. 11 based on the reference result. It is determined whether or not the insertion portion 2 connected to the device 3 is the same as the insertion portion 2 connected to the rotation device 3 in step S1 in FIG.

  When the identification information determination unit 5d and the external device detect that the first identification information and the second identification information are different (step S5 in FIG. 11), the identification information determination unit 5d and the external device make the rotation device 3 in step S4 in FIG. It is determined that the connected insertion section 2 is different from the insertion section 2 connected to the rotating device 3 in step S1 in FIG. 11, and stores the second identification information in addition to the existing identification information ( Along with step S6) in FIG. 11, a process for enabling updating of information on the subject is performed (step S10 in FIG. 11).

  When the identification information determination unit 5d and / or the external device detects that the first identification information and the second identification information are the same (step S5 in FIG. 11), step S4 in FIG. In FIG. 11, it is determined that the insertion portion 2 connected to the rotation device 3 is the same as the insertion portion 2 connected to the rotation device 3 in step S1 of FIG.

  When the identification information determination unit 5d and the external device detect that the first identification information and the second identification information are the same, an input instruction from an input unit (not shown) such as a keyboard is given. A process for making it impossible to update the information about the subject is performed by not accepting the information (step S7 in FIG. 11).

  Furthermore, when the identification information determination unit 5d detects that the first identification information and the second identification information are the same, by controlling the signal processing unit 5b, for example, instead of the subject image, for example, An image as shown in FIG. 10 in which notification information 6c for urging the user to replace the connected insertion section 2 (scope) with another image is superimposed on a predetermined image such as a monochrome image 6b. Until it is detected that the insertion portion 2 has been removed, it is displayed on the monitor 6 (step S8 and step S9 in FIG. 11). Further, the identification information determination unit 5d detects that the insertion unit 2 has been removed via the connection detection unit 3d (step S9 in FIG. 11), and then the insertion unit 2 connected to the rotation device 3 is detected. Each process according to step S4 and subsequent steps in the flowchart of FIG. 11 is performed.
