In such an endoscope apparatus, an image acquired by the imaging apparatus is transmitted to the main body of the endoscope apparatus through an insertion unit, and is displayed on a display unit such as a display through image processing or the like.

  Moreover, in an endoscope apparatus, in order to point an imaging device toward an observation target inside a test object, it is common to include a bending mechanism that bends the distal end of the insertion portion. In addition, since light often does not reach the inside of the test object, it is also conventional to brighten (illuminate) the field of view of the imaging device using an illumination mechanism including a light emitting member such as a light emitting diode (LED). It is performed in a endoscope apparatus.

  In recent years, in order to make the endoscope apparatus easier to use, an operation unit that operates an insertion unit and the above-described display unit are integrated, and the one that is miniaturized to the extent that it can be held with one hand has been proposed. (For example, refer to Patent Document 1).

Step S1 is complete | finished now and it transfers to step S2.

Step S <b> 2 is a step of reading the configuration identification information of the scope unit connected to the main body 20 into the main body 20.
In step S2, in a state where the scope unit 100 is attached to the main body unit 20, the setting file F100 in which the configuration identification information I100 is described is read from the configuration storage unit 195 of the scope unit 100 into the RAM 92B of the control unit 90.
Step S2 is complete | finished now and it transfers to step S3.

Step S3 is a step of determining the presence or absence of configuration identification information.
In step S3, first, it is confirmed whether the operation of reading the configuration identification information into the RAM 92B has been successful and whether the configuration identification information has been damaged.
In the present embodiment, the configuration identification information I100 and I200 are stored in the scope unit 100 and the scope unit 200, respectively. However, the scope identification unit may not include configuration identification information in a scope unit that does not require a bending operation. is there. In this case, a configuration may be adopted in which it is detected that no configuration identification information is provided by detecting that there is no response from the scope unit even when a predetermined timeout time stored in the ROM 92A has elapsed.

If there is no configuration identification information indicating that the bending drive unit 160 or the bending drive unit 260 is present, step S3 ends and the process proceeds to step S4.
In the present embodiment, the configuration identification information I100, I200 of the scope units 100, 200 stores that the electric bending method is stored in the bending method parameter P200, so that the scope unit is driven to be bent in step S3. As a result of the determination, step S3 ends and the process proceeds to step S5.

Step S4 is a step of setting an operation in which the control unit 90 responds to the input operation input to J / S41.
In step S4, the operation input input to the J / S 41 is an instruction operation input for selecting an option displayed on the display screen 51 or designating a part of the video displayed on the display screen 51. The control unit 90 is set so as to recognize. At this time, the operation of tilting the J / S 41 by the user is referred to by the control unit 90, and the control unit 90 moves the cursor displayed on the display screen 51 to indicate a point on the display screen 51. Move in conjunction with the movement.
Thereby, step S4 is completed, and the operation of J / S41 is set to be used for the operation of the display screen 51.

Step S5 is a step of setting an operation in which the control unit 90 responds to the input operation input to J / S41.
In step S5, the control unit 90 switches between the driving operation input for operating the bending driving unit 160 provided in the scope unit 100 and the above-described instruction operation input so as to recognize the operation input input to the J / S 41. Set to At this time, the operation of J / S 41 can be switched alternately by pressing the button 42, for example.
Thereby, step S5 is completed, and the operation of J / S41 is set to be used for both the operation of the bending drive unit 160 and the operation of the display screen 51.

  Thus, the attachment process for attaching the scope unit 100 or the scope unit 200 to the main body 20 is completed.

  When the attachment process is completed, a method selection process for selecting a bending method for bending the scope unit in the endoscope system 1 is subsequently started.

As shown in FIG. 7, step S10 is a step of determining whether or not the scope unit attached to the main body 20 shown in FIG. 2 can be bent.
In step S10, if there are the bending method parameters P100 and P200 based on the configuration identification information I100 or the configuration identification information I200 stored in the RAM 92B in step S2, step S10 ends, and the process proceeds to step S11.
For example, when a scoring unit that is not driven to bend is attached to the main body 20, the configuration identification information does not include information on the bending method parameter, so step S10 ends and the method selection process ends.

Step S11 is a step of determining whether or not there is an input operation to J / S41 by the user.
In step S11, the control unit 90 refers to the resistance value of the potentiometer 41A of J / S41, and determines whether or not J / S41 is in the neutral position from the resistance value of the potentiometer 41A. When the user inputs an operation of J / S41, J / S41 is tilted so as to be located at a position different from the neutral position, and therefore the resistance value of potentiometer 41A is different from that when J / S41 is in the neutral position.

  In the control unit 90, if the resistance value when J / S 41 is in the neutral position and the resistance value of the potentiometer 41A when step S11 is executed, step S11 ends, and the process proceeds to step S12.

  When the user does not input J / S41, J / S41 is in the neutral position. If the control unit 90 determines that J / S41 is in the neutral position, step S11 ends and the method selection process ends. To do.

Step S12 is a step of selecting a bending method of the scope unit.
In step S12, the control unit 90 selects a bending method of the scope unit based on the configuration identification information read into the RAM 92B. In the present embodiment, since the bending method parameter P100 of the configuration identification information I100 of the scope unit 100 stores that the bending method of the scope unit 100 is the electric bending method, in step S12, the bending method of the scope unit 100 is stored. Is determined to be an electric bending method, step S12 ends, and the process proceeds to step S13.

  In step S12, if a bending method other than electric bending is stored in the bending method parameter, step S12 ends and the process proceeds to step S14. In this embodiment, as an example of a bending method other than the electric bending method, it is conceivable that the scope unit includes a bending drive unit that performs a bending operation of the bending portion by fluid pressure. The configuration and operation of the scope unit having a bending method using fluid pressure will be described later.

Therefore, step S100 ends and the process proceeds to step S101.

  When the scope unit 200 is attached to the main body unit 20, the bending method parameter P200 of the configuration identification information I200 stores that the bending operation of the bending unit 213 by the bending drive unit 260 of the scope unit 200 is in four directions. Thus, step S100 ends and the process proceeds to step S201.

The illumination drive parameter P722 for generating a drive signal for driving the light source unit 770 includes voltage and current supplied to the LED 771 and time width information indicating the light emission timing when the LED 771 emits light intermittently.

  When the scope unit 700 is attached to the main body unit 20, the configuration identification information is read from the configuration storage unit 795 to the RAM 92B. Then, similarly to the scope unit 200 described above, a driving signal for performing the bending operation of the bending portion 213 can be generated in the bending drive circuit 93, and a list of light emitting methods for causing the LED 771 to emit light is listed on the display screen 51. The display is based on the information P721, and the light emission method of the LED 771 can be selected on the display screen by tilting J / S41.

  As described above, according to the scope unit 700 of the present modified example, the configuration identification information includes the illumination parameter P720 including the list information P721 and the illumination drive parameter P722. When attached and used, it is possible to select the light emitting method equipped in the scope unit by looking at the display screen 51. As a result, even if a plurality of scope units equipped with different light emission methods are used for each scope unit, it is easy to understand how to use the scope unit.

  Note that the scope unit 700 of this modification is also the second scope unit to be added to the scope unit 100 or the scope unit 200, similarly to the scope unit 400, scope unit 400A, scope unit 500, scope unit 500A, and scope unit 700 described above. Can be provided in the endoscope system 1. In this case, compared to the configuration in which the illumination light of the LED 71 is transmitted to the irradiation unit 12A using the light guide 72, the transmission loss of the illumination light is small even if the length of the second insertion unit 710 is increased, and the first The two insertion portions 710 can be configured to be thin.

  In addition to the scope unit 700, examples of the scope unit having a different illumination unit configuration include a scope unit that employs a light source other than an LED. For example, a scope unit that employs a halogen lamp or a laser diode (LD) as a light source is conceivable. Even in this case, configuration identification information including light emitting methods and parameters corresponding to these light sources is stored in the configuration storage unit. Thus, the control unit 90 of the main body unit 20 can control each light source.

(Modification 5)
Below, the structure of the modification 5 of the endoscope system 1 of this embodiment is demonstrated with reference to FIG.14 and FIG.15. FIG. 14 is a block diagram showing a configuration of Modification 5 of the endoscope system 1 of the present embodiment. FIG. 15 is a block diagram showing still another configuration example of the modification example 5 shown in FIG.
The scope unit 100 shown in FIG. 14 is provided with a CCD 11A in the imaging unit 11, and the scope unit 800 shown in FIG. 14 is provided with a CMOS 811A in the imaging unit 11 instead of the CCD 11A. The scope unit 800 is a second scope unit provided in addition to the scope unit 100.

  Further, the scope unit 800 is provided with a configuration storage unit 895 instead of the configuration storage unit 195. Configuration identification information is stored in the configuration storage unit 895, and the configuration identification information stored in the configuration storage unit 895 is image information transmitted from the CCD 11A or the CMOS 811A to the display control unit 52 of the display unit 50. The operation | movement procedure for converting into the signal for displaying on 51 is included.

  In addition, the configuration identification information stored in the configuration storage unit 195 or the configuration storage unit 895 is read into the RAM 92B of the control unit 90. For example, when the scope unit 800 is attached to the main body unit 20, the RAM 92B stores parameters for operating the display control unit 52 of the display unit 50 in addition to parameters for operating the bending drive unit 160. ing.

  The display control unit 52 converts the image signal transmitted from the CMOS 811A to the display control unit 52 into an image signal for display on the display screen 51 based on the parameters stored in the RAM 92B.

  In the present modification, even if the imaging devices provided in the imaging unit 11 are different, the image signal of the imaging device is displayed on the display screen 51 by reading the configuration identification information from the scope unit 100 or the scope unit 800 into the RAM 92B of the control unit 90. The image can be converted into a displayable format. Thereby, it is possible to exchange and use a plurality of scope units with different types of imaging elements.

  The camera is not limited to the configuration in which the operation of the display control unit 52 is switched depending on the parameters, and a plurality of different camera control units (for example, CCU 52A and CCU 852A shown in FIG. 15) are provided on the display control unit 52 and used based on the configuration identification information. A control unit may be selected.

  In addition, as another example of a scope unit having a different type of image sensor, a scope unit that employs an image sensor having a different number of effective pixels from the CCD 11A, for example, can be used. For example, when a CCD having a larger number of effective pixels than the CCD 11A is employed, a good enlarged image can be obtained even if the maximum zoom magnification of the digital zoom process is higher than that of the scope unit 100 equipped with the CCD 11A. Correspondingly, the configuration identification information can include information on the maximum magnification of the digital zoom in the display unit 50. In this case, the image sensor with a small number of effective pixels does not zoom to a magnification that does not allow the object to be observed well, and the image sensor with a large number of effective pixels has a high magnification without special settings. The operation of the endoscope system 1 can be simplified.

The image signal to be displayed may have different electrical characteristics when it reaches the display control unit 52 according to the length of the insertion unit.

Here, the configuration identification information stored in each of the second insertion unit 910A, the second insertion unit 910B, and the second insertion unit 910C is read into the RAM 92B of the control unit 90, and is based on the configuration identification information read into the RAM 92B. Thus, the image signal that has reached the display control unit 52 is corrected and converted into a video signal that can be displayed on the display screen 51.
