Description

  The present invention relates to an endoscope apparatus in which a display device is rotatably attached to an endoscope or an apparatus main body to which the endoscope is connected.

  As is well known, endoscope apparatuses are widely used in the industrial field. Endoscopic devices used in the industrial field are used to observe wounds, corrosion, etc. at the test site by inserting the elongated insertion part of the endoscope into the jet engine, which is the test site, or into the piping of the factory. And various treatments can be performed.

  Here, in an endoscope apparatus used in the industrial field, an apparatus main body to which the endoscope is connected is configured to be small so that it can be transported together with the endoscope when inspecting a region to be examined. In addition, a configuration in which a belt for carrying the apparatus main body on a shoulder of an operator and the like is provided on a small apparatus main body is well known. That is, a shoulder type endoscope apparatus is well known.

  In the shoulder type endoscope apparatus, a display device for displaying an image of a region to be examined imaged by the endoscope is provided in the apparatus main body. In general, the display device includes a display module, a built-in object such as a control board that controls display of the display module, and an exterior member of the display device that covers the built-in object. Further, a configuration in which the display device is detachable from the apparatus main body is also well known, and is disclosed in, for example, Patent Document 1.

  FIG. 10 is a perspective view showing a configuration of a conventional endoscope apparatus, and FIG. 11 is a diagram showing a state in which a display device is suspended from a suspension stay of the apparatus main body of FIG. It is.

  As shown in FIG. 10, in the endoscope apparatus 100 disclosed in Patent Document 1, it is the upper surface in the height direction H of the apparatus main body 102 to which the endoscope 101 is connected, and is the front side in FIG. Further, a suspension stay 103 is provided, and the display device 110 is configured to be suspended and fixed by a fixing screw 104 on the lower surface in the height direction H of the suspension stay 103.

Specifically, as shown in FIG. 11, the exterior member 110 g that protrudes upward in the height direction H from the frame portion 119 of the exterior member 110 g in the display device 110 is fixed to the upper surface in the height direction H of the display device 110. 111, and the fixing screw 104 can be screwed into the fixing nut 113 provided in the fixing portion 111 through the screw hole 103n formed in the hanging stay 103.

  By the way, since the shoulder type endoscope apparatus is used with a belt placed on the shoulder of the operator, for example, the apparatus main body may be unexpectedly dropped. In this case, as shown in FIG. 11, when the apparatus main body 102 falls to the floor or the like, a force F in the dropping direction (impact force at the time of collision) is applied to the display device 110.

  More specifically, when the apparatus main body 102 falls to the floor or the like, the suspension stay 103 to which the display device 110 disclosed in Patent Document 1 is attached is usually formed of metal or the like. By F, there is no significant deformation.

  However, since the display device 110 has a structure in which the exterior member 110g configured by the frame portion 119 and the fixing portion 111 is fixed to the suspension stay 103 by the fixing screw 104, the device main body 102 falls on the floor or the like. The force F in the dropping direction is applied to the exterior member 110g of the display device 110.

  Here, when the exterior member 110g of the display device 110 is made of, for example, resin, if the force F in the dropping direction at the time of dropping is large, the resin cannot absorb the force F, and the exterior member is weak in strength. The force F was applied and there was a possibility of breaking. Note that the breakage of the exterior member due to the dropping of the apparatus main body 102 is considered to be particularly high when the endoscope apparatus is used in a place where the temperature is low.

  FIG. 12 is a diagram showing, as an example, a state in which a crack has occurred in the exterior member of the display device when the device main body is dropped.

  Specifically, as shown in FIGS. 11 and 12, a built-in object such as a display module or a control board incorporated in the frame portion 119 in the exterior member 100 g of the display device 110 is displayed on the exterior member 110 g in the frame portion 119. A holding member 114 such as a metal frame is fixed to the surface 110gf surrounding the display surface of the module in a plan view by screws 115, so that the holding member 114 is held in the exterior member 110g.

  From this, when the apparatus main body 102 is dropped on the floor or the like, if the force F in the dropping direction accompanying the dropping of the apparatus main body 102 is applied to the exterior member 110g attached to the suspension stay 103, the exterior of the frame 119 In the member 110g, a force P in the dropping direction is applied to the screw 115 fixed to the built-in object and the surface 110gf.

  At this time, since the fixing portion 111 of the exterior member 110g is fixed to the suspension stay 103 by the fixing screw 104 and does not move, the suspension stay is applied to the frame portion 119 in the exterior member 100g by the force P in the dropping direction. A shearing force S is applied from 103.

  As a result, a display window 116 that exposes the display surface of the display module is formed at a portion where the stress of the frame portion 119 tends to concentrate (a portion where the strength of the exterior member is weak), for example, the surface 110 gf as shown in FIG. There is a possibility that stress concentrates on the corners and cracks K are generated from the corners.

  The above problems can be prevented if the exterior member 110g is formed of metal or the like. However, in this case, the exterior member 110g becomes heavy, and thus it is difficult to reduce the weight of the display device 110. In addition, there is a problem that if the force in the dropping direction is large and the exterior member 110g is deformed, the built-in object may be damaged along with the deformation.

  The present invention has been made in view of the above problems, and is an endoscope apparatus capable of reducing breakage of an exterior member of a display device when the device main body is dropped on a floor or the like while maintaining a weight reduction of the display device. The purpose is to provide.

  In order to achieve the above object, an endoscope apparatus according to the present invention is an endoscope apparatus in which a display device is rotatably attached to an endoscope or an apparatus main body to which the endoscope is connected. The display device includes: an exterior member of the display device; a built-in object provided in the exterior member; and fixing the built-in object to the endoscope or the apparatus body via the exterior member. An endoscope apparatus comprising: a first fixing member that fixes an apparatus to the endoscope or the apparatus main body.
