The first bending portion 136a extends from the operation portion holding portion 135 and is curved in a circumferential shape, and the second bending portion 136b is configured to bend in an arc shape continuously to the distal end portion of the first bending portion 136a. The first bending portion 136a extends, for example, from the end of the longitudinally extending portion 135b of the operation portion holding portion 135 in an arc shape along the front side surface of the lower cushioning material 130, and further to draw a semicircle. It extends in an arc shape and is adjacent to the laterally extending portion 135 a of the operation portion holding portion 135. For example, the first curved portion 136a has a depth in the height direction of the lower cushioning material 130 that is deepest at a portion connected to the end of the longitudinally extending portion 135b of the operation portion holding portion 135, and the operation portion holding portion. The bottom portion is inclined so as to be shallowest at a portion adjacent to the laterally extending portion 135a of 135. In other words, the depth of the bottom surface of the first bending portion 136a decreases as the base end portion continuous to the operation portion holding portion 135 shifts to the distal end portion continuing to the second bending portion 136b.

  The universal tube holding part 136 is curved in a counterclockwise direction (forward direction) set in advance in plan view, and the distal end of the universal tube 230 is held more than the portion where the proximal end of the universal tube 230 is held. The portion is formed with a shallower depth. That is, the portion where the tip of the universal tube 230 is held is formed so that the depth of the bottom surface becomes smaller. Therefore, the distal end of the universal tube 230 can be disposed in the vicinity of the upper surface 130a of the lower cushioning material 130 to facilitate storage and removal from the universal tube holding part 136.

  The first bending portion 136a has a bottom surface that is inclined such that the depth gradually decreases as it moves from a base end portion continuous with the operation portion holding portion 135 to a distal end portion continuous with the second bending portion 136b. In other words, the depth of the bottom surface decreases as the base end portion continuous to the operation portion holding portion 135 shifts to the distal end portion continuous to the second bending portion 136b. Therefore, when the universal tube 230 is accommodated in the first bending portion 136a, the universal tube 230 can be accommodated in a gently spiraled state, and a load is not locally applied to a part of the universal tube 230. it can.

  For example, the second bending portion 136b extends substantially linearly from the terminal end of the first bending portion 136a adjacent to the laterally extending portion 135a of the operation portion holding portion 135 toward the left side surface of the lower cushioning material 130. Further, it intersects with the longitudinally extending portion 135b of the operation portion holding portion 135 and is further curved in an arc shape so as to be close to the left side surface of the lower cushioning material 130. The second curved portion 136b extends from a position close to the left side surface of the lower cushioning material 130 so as to be curved in an arc shape along the front side surface of the lower cushioning material 130. The second bending portion 136b overlaps the first bending portion 136a at a position closer to the front side surface of the lower cushioning material 130 than the first bending portion 136a, and is generally linear along the front side surface of the lower cushioning material 130. It extends to.

  That is, the second bending portion 136b has a configuration in which the second bending portion 136b is bent along the first bending portion 136a at a position distant from the first bending portion 136a in the radial direction and then merges with the first bending portion 136a again. The depth of the joining portion of the second bending portion 136b that joins the first bending portion 136a is shallower than that of the first bending portion 136a. According to this configuration, the universal tube 230 held by the second bending portion 136b can be accommodated on the universal tube 230 held by the first bending portion 136a.

  The depths of the first curved portion 136a and the second curved portion 136b in the height direction of the lower cushioning material 130 are, for example, the first curved portion 136a in a portion extending linearly along the front side surface of the lower cushioning material 130. The second curved portion 136b is shallower than the second curved portion 136b. That is, the depth of the bottom surface of the second bending portion 136b is smaller than that of the first bending portion 136a. The second curved portion 136 b further extends obliquely rearward to the right toward the middle portion of the right side surface of the lower cushioning material 130 and continues to the connector portion holding portion 137.

  The connector part holding part 137 is a recessed part corresponding to the shape of the connector part 240 of the endoscope 200. The connector part holding | maintenance part 137 is provided so that a space | gap may be formed around the part which accommodates the connection sleeve 242 for light sources of the connector part 240, for example. Further, when the connector part holding part 137 accommodates and holds the connector part 240 of the endoscope 200 in the bottom part of the connector part holding part 137, the upper surface of the connector part 240 in the height direction of the lower cushioning material 130 is lower. The connector portion 240 may have an inclination corresponding to the tapered shape so as to be substantially parallel to the upper surface 130a of the buffer material 130.

  The connector part 240 has a pair of side surfaces inclined in a tapered shape. The connector part holding part 137 has a bottom surface that contacts one of the pair of side surfaces of the connector part 240, and the other side surface of the connector part 240 is parallel to the upper surface 130 a of the lower cushioning material 130. So as to be inclined.

  The insertion part holding part 138 is provided continuously with the operation part holding part 135 and has a configuration for holding the insertion part 220 extending from the operation part 210 of the endoscope 200 in a curved state. The insertion portion holding portion 138 is curved in a clockwise direction (counterclockwise direction) set in advance in a plan view, and the portion where the proximal end of the insertion portion is held rather than the portion where the proximal end of the insertion portion is held. The depth is shallower. That is, the depth of the bottom surface is smaller in the portion where the proximal end of the insertion portion is held than in the portion where the proximal end of the insertion portion is held.

  The insertion portion holding portion 138 is, for example, a generally annular groove for winding and accommodating the flexible insertion portion 220 of the endoscope 200, and is provided with an intermediate curve and a rear bending portion (third bending portion) 138a. Part (fourth curved part) 138b and a front straight part (straight part) 138c. The backward bending portion 138a has a configuration that extends from the operation portion holding portion and curves in an arc shape.

  The rear curved portion 138a extends, for example, from the end of the laterally extending portion 135a of the operation portion holding portion 135 generally linearly along the rear side surface of the lower cushioning material 130, and further on the right side of the lower cushioning material 130. It curves in an arc shape along the side surface and extends linearly along the side surface in the vicinity of the side surface. Further, the rear curved portion 138a extends from the vicinity of the right side surface of the lower cushioning material 130 so as to be curved in an arc shape along the front side surface of the lower cushioning material 130, and is continuous with the intermediate curved portion 138b.

  The intermediate bending portion 138b has a configuration that is curved in an arc shape continuously to the rear bending portion 138a. The intermediate curved portion 138b extends, for example, linearly along the side surface in the vicinity of the front side surface of the lower cushioning material 130, and further curved in a circular arc shape so as to approach the left side surface of the lower cushioning material 130. It extends. Further, the intermediate curved portion 138b extends from the position close to the left side surface of the lower cushioning material 130 so as to intersect with the longitudinally extending portion 135b of the operation portion holding portion 135, and extends in an arc shape. 138c.

  The intermediate bending portion 138b of the insertion portion holding portion 138 and the second bending portion 136b of the universal tube holding portion 136 can be formed as a common groove with respect to the lower cushioning material 130. That is, the universal tube holding part 136 and the insertion part holding part 138 have grooves that are partially common to each other. In this case, in the height direction of the lower cushioning material 130, the lower side of the common groove is the second curved portion 136b of the universal tube holding portion 136, and the upper side (groove opening side) of the common groove is the insertion portion holding portion. 138 is an intermediate curved portion 138b. Therefore, the insertion part 220 can be disposed on the universal tube 230.

  The front straight portion 138c has a configuration that extends straight and continuously to the intermediate curved portion 138b. The front straight portion 138c of the insertion portion holding portion 138 linearly extends diagonally rightward and rearward toward the right side surface of the lower cushioning material 130 along the laterally extending portion 135a of the operation portion holding portion 135, and the rear bending portion. Crossing 138a. In the height direction of the lower cushioning material 130, the depth of the front straight portion 138c is shallower than the depth of the rear curved portion 138a at the tip portion near the right side surface of the lower cushioning material 130 that intersects the rear curved portion 138a. ing. That is, in the height direction of the lower cushioning material 130, the depth of the bottom surface of the front straight portion 138c is equal to It is smaller than the depth. The front straight portion 138c has a depth that gradually decreases in the height direction of the lower cushioning material 130 from the connecting portion with the intermediate curved portion 138b toward the tip, that is, the depth of the bottom surface gradually decreases. As such, the bottom may be inclined. According to such a configuration, the distal end of the insertion portion 220 can be arranged in the vicinity of the upper surface 130a of the lower cushioning material 130 to facilitate removal.

  The cavity part 133 is a recessed part provided in the upper surface 130a of the lower shock absorbing material 130, for example. The cavity part 133 includes, for example, a first cavity part 133a formed inside the first curved part 136a of the universal tube holding part 136, a second cavity part 133b adjacent to the front of the connector part holding part 137, and a connector part. And a third cavity portion 133c adjacent to the rear of the holding portion 137. Moreover, the cavity part 133 can have the 4th cavity part 133d and the 5th cavity part 133e in the corner | angular part of the front end of the lower shock absorbing material 130, for example.

  The convex part 132 is extended along the both-sides edge of the lower shock absorbing material 130, for example. In the illustrated example, the protrusion 132 extends along both side edges extending in the vertical direction on both lateral sides of the lower cushioning material 130, and projects upward from the upper surface 130 a of the lower cushioning material 130. Although illustration is omitted, the lower cushioning material 130 may have convex portions extending along both front and rear side edges extending in the lateral direction.

  For example, as shown in FIG. 1, the convex portion 132 may have an inclined surface 132 a at the upper end portion. The inclined surfaces 132a are formed, for example, on both lateral edges of the lower cushioning material 130 on the inner side of the top of the convex portion 132 extending in the vertical direction, and the inner side of the lower cushioning material 130 is located on the inner side of the lateral outer side. It inclines below so that it may approach 130a. In addition, the laterally outer surfaces of the pair of convex portions 132 constitute part of the left and right side surfaces of the flat lower cushioning material 130 without a step.

  For example, as shown in FIG. 1 and FIG. 3, the notch portion 134 is a concave portion that is recessed rearwardly at the center of the front side surface of the lower cushioning material 130. The notch 134 is formed continuously from the lower surface of the lower cushioning material 130 to the upper surface 130a, for example. The notch part 134 avoids interference with the stopper of the handle 115 disposed inside the front side wall 112 of the outer box 110 shown in FIG. 1, and both ends of the band plate part of the handle 115 are arranged inside the outer box 110. Have a width in the horizontal direction and a depth in the vertical direction.

  FIG. 5 is a perspective view of a state in which the lower cushioning material 130 is accommodated in the outer box 110 of the endoscope case 100 shown in FIG.

  The outer dimension in the horizontal direction of the lower cushioning material 130 is slightly smaller than the inner dimension in the horizontal direction of the outer box 110. Thereby, a gap is provided between the left and right side surfaces of the lower cushioning material 130 and the left and right side walls 112 of the outer box 110 for inserting the second lid insertion portions 113b on both sides in the lateral direction of the upper lid 113. . In the endoscope case 100 of the present embodiment, as described above, the corrugated paper that forms the outer portion of the left and right side walls 112 of the outer box 110 is folded back to the inner side of the opening 110a at the upper end portion. 112a is provided. Therefore, the upper part of the inner surface of the left and right side walls 112 of the outer box 110 covered with the folded portion 112a is a smooth exterior surface having the gloss of corrugated cardboard which is the material of the outer box 110.

  Further, the top portions of the pair of convex portions 132 extending forward and backward at the left and right side edges of the lower cushioning material 130 are positioned above the lower ends of the folded portions 112 a of the left and right side walls 112 of the outer box 110. Thereby, the interior surface of the corrugated paper exposed on the inner surface below the lower end of the folded portion 112 a of the left and right side walls 112 of the outer box 110 is hidden under the lower cushioning material 130. Therefore, it is not necessary to extend the lower end of the folded portion 112 a to the lower ends of the left and right side walls 112 of the outer box 110 in order to cover the interior surface exposed on the inner surfaces of the left and right side walls 112 of the outer box 110. Accordingly, the cost of the outer box 110 can be reduced by saving cardboard paper.

  Further, as described above, the upper folded portion 112a on the inner surface of the left and right side walls 112 of the outer box 110 is opened at the upper end of the side wall 112 by the corrugated cardboard constituting the outer portion of the left and right side walls 112 of the outer box 110. It is formed by being folded downward to the inside of the portion 110a. Therefore, the lower end portion of the folded portion 112a is urged in the lateral direction toward the inside of the opening portion 110a by the elasticity of the corrugated cardboard, and on the lower side of the convex portion 132 of the lower cushioning material 130, It abuts on the side surface. Thereby, the position of the horizontal direction of the lower shock absorbing material 130 accommodated in the outer box 110 is positioned to a certain extent.

  Further, the inner surface of the bottom wall 111 of the outer box 110 and the inner surfaces of the front and rear side walls 112 of the outer box 110 are interior surfaces where the surface of the material is exposed as described above. Therefore, when the surface roughness of the interior surface is higher than the surface roughness of the exterior surface, or when the static friction coefficient of the interior surface is higher than the static friction coefficient of the exterior surface, the lower surface of the lower cushioning material 130 accommodated in the outer box 110 The inner surface can be brought into contact with the front and rear side surfaces, and the relative movement of the outer box 110 and the lower cushioning material 130 can be suppressed.

  Further, as shown in FIG. 1, the lower cushioning material 130 has a notch 134 that is recessed rearward at the center of the front side surface. This avoids interference between the stopper of the handle 115 disposed inside the front side wall 112 of the outer box 110 and the lower cushioning material 130 and accommodates both ends of the band plate portion of the handle 115 inside the outer box 110. can do. Therefore, for example, when carrying the endoscope case 100, the handle 115 is pulled out to project forward in an arc shape, and when the endoscope case 100 is stored, the handle 115 is pushed backward to move the front side of the outer box 110. It can be accommodated flat along the side wall 112.

The lower cushioning material 130 arranged in this manner has a holding portion 131 for holding the endoscope 200 on the upper surface 130a, and the upper cushioning material 140 covers the entire upper surface 130a including the holding portion 131 of the lower cushioning material 130. It is a feature. More specifically, the upper cushioning material 140 has, for example, a rectangular planar shape corresponding to the planar shape of the lower cushioning material 130. Further, the upper cushioning material 140 has a rectangular flat plate shape whose dimension in the height direction is smaller than the dimension in the vertical direction and the horizontal direction.

  Further, when the upper cushioning material 140 is disposed on the lower cushioning material 130 inside the outer box 110 and viewed from right above the opening 110a of the outer box 110, the outer edge of the upper cushioning material 140 and the lower cushioning material are disposed. At least part of the outer edge of the material 130 overlaps vertically. Further, in the portion where the outer edge of the upper cushioning material 140 and the outer edge of the lower cushioning material 130 do not overlap vertically, the outer edge of the lower cushioning material 130 is disposed inside the outer edge of the upper cushioning material 140. Further, the upper cushioning material 140 does not have a through hole or a notch communicating from the upper end surface to the lower end surface of the upper cushioning material 140.

  That is, in the state where the lower cushioning material 130 and the upper cushioning material 140 are arranged one above the other, one of the following states occurs. First, the entire planar contour of the lower cushioning material 130 matches the planar contour of the upper cushioning material 140. In addition, a part of the planar outline of the lower cushioning material 130 matches the planar outline of the upper cushioning material 140, and the other part is included inside the planar contour of the upper cushioning material 140. Then, the entire planar contour of the lower cushioning material 130 is included inside the planar contour of the upper cushioning material 140. Furthermore, the lower surface 140 b of the upper cushioning material 140 is disposed so as to face the entire holding portion 131 of the lower cushioning material 130 and the entire upper surface 130 a of the lower cushioning material 130 excluding the holding portion 131.

  As shown in FIG. 6, the upper cushioning material 140 has, for example, concave portions 141 a, 141 b, and 141 c at positions corresponding to the holding portions 131 of the lower surface 140 b facing the lower cushioning material 130. More specifically, the left-side rear circular concave portion 141a and the rectangular concave portion 141b of the upper cushioning material 140 are opposed to, for example, the operation portion holding portion 135 of the lower cushioning material 130 shown in FIG.

The depth of the left recess 143a of the upper surface 140a of the upper cushioning material 140 is shallower than the depth of the right recess 143b. As a result, in the upper cushioning material 140, the thickness of the portion facing the operation portion holding portion 135 is made thicker than the thickness of the portion facing the connector portion holding portion 137. The upper cushioning material 140 may not have the frame-like portion 142. Further, the shape, size, arrangement, number, etc. of the recesses 141a, 141b, 141c of the upper cushioning material 140 are not particularly limited and are arbitrary.

  In addition, the upper cushioning material 140 has, for example, a handle portion 144 provided in a step shape on both side edges of the upper surface facing the upper lid 113 of the outer box 110. The handle portion 144 can be formed, for example, at the center of both lateral edges of the upper cushioning material 140 in the lateral direction. Note that the handle portion 144 may be formed at the center portion in the lateral direction of the front and rear side edges of the upper cushioning material 140. The handle portion 144 is formed in a stepped shape recessed downward in the middle portion of the side edge of the upper cushioning material 140, and has a bottom wall and an inner wall.

  The upper and right sides of the handle part 144 formed in a concave shape on the right side edge of the upper cushioning material 140 are opened, and the upper side and the left side of the handle part 144 formed in a concave shape on the left side edge of the upper cushioning material 140.

Further, the upper cushioning member 140 is formed with the handle 144 so that the vertical center portion of the vertical frame portion 142b of the frame-like portion 142 along the left and right side edges is notched from the outside to the inside in the horizontal direction. In addition, a thin portion 145 is formed between the handle portion 144 and the recesses 143a and 143b.

  Moreover, the upper shock absorbing material 140 has the recessed part 146 engaged with the convex part 132 of the lower shock absorbing material 130, for example in the lower part of a both-sides edge. For example, the recess 146 is formed in a stepped shape in the corner between the lower surface 140b of the upper cushioning material 140 and the left and right side surfaces in an upward and lateral direction, and extends over the entire length in the vertical direction. . The recess 146 has an upper wall surface facing downward and a side wall surface facing laterally outward.

  The upper cushioning material 140 has a stepped portion 147 at a position corresponding to the handle 115 attached to the side wall 112 of the outer box 110, for example. The stepped portion 147 is recessed upward and rearward, for example, at the central portion of the corner between the lower surface 140b of the upper cushioning material 140 facing the lower cushioning material 130 and the front side surface. The step portion 147 has an upper wall surface facing downward, a rear wall surface facing forward, and left and right side wall surfaces, and is disposed on the notch portion 134 of the lower cushioning material 130.

The bottom portion is inclined so as to be shallowest at a portion adjacent to the laterally extending portion 135 a of the portion holding portion 135. Further, the second bending portion 136 b extends substantially linearly toward the left side surface of the lower cushioning material 130, and intersects the longitudinal extending portion 135 b of the operation portion holding portion 135. As a result, the universal tube 230 of the endoscope 200 can be stored in an intersecting manner on the operation unit 210 held by the longitudinally extending portion 135b of the operation unit holding unit 135.

  Thereafter, the universal tube 230 of the endoscope 200 is further accommodated while being bent by the second bending portion 136b of the universal tube holding portion 136 of the lower cushioning material 130. Here, the second bending portion 136b overlaps the first bending portion 136a at a position closer to the front side surface of the lower cushioning material 130 than the first bending portion 136a, and extends along the front side surface of the lower cushioning material 130. It extends almost linearly. In addition, the depth of the first curved portion 136a and the second curved portion 136b in the height direction of the lower cushioning material 130 is such that the first curved portion 136a is a portion that extends linearly along the front side surface of the lower cushioning material 130. The second curved portion 136b is shallower than the second curved portion 136b. Accordingly, the universal tube 230 of the endoscope 200 is placed on the second curved portion 136b so as to be adjacent to the front side of the universal tube 230 of the endoscope 200 held by the first curved portion 136a of the universal tube holding portion 136. Can be accommodated and held.

  Thereafter, the universal tube 230 of the endoscope 200 is further accommodated and held in the second curved portion 136b extending obliquely rearward to the right toward the middle portion of the right side surface of the lower cushioning material 130, and the connector of the endoscope 200 is retained. The portion 240 is accommodated and held in the connector portion holding portion 137 of the holding portion 131 of the lower cushioning material 130. Here, as described above, the bottom portion of the connector portion holding portion 137 has an inclination corresponding to the tapered shape of the connector portion 240. Thereby, when the connector part 240 of the endoscope 200 is accommodated and held in the connector part holding part 137 of the lower cushioning material 130, the upper surface of the connector part 240 in the height direction of the lower cushioning material 130 is placed on the lower cushioning material 130. It can be stably held between the upper cushioning member 140 and substantially parallel to the upper surface 130a.

  Next, the insertion part 220 connected to the operation part 210 of the endoscope 200 is accommodated in the insertion part holding part 138 of the holding part 131 of the lower cushioning material 130. Specifically, a portion close to the operation portion 210 of the insertion portion 220 of the endoscope 200 having flexibility is housed in the rear bending portion 138a of the insertion portion holding portion 138 shown in FIG. Furthermore, the intermediate part of the insertion part 220 of the endoscope 200 is accommodated in the intermediate bending part 138 b of the insertion part holding part 138.

  Here, as described above, the intermediate bending portion 138 b of the insertion portion holding portion 138 and the second bending portion 136 b of the universal tube holding portion 136 are formed as a common groove with respect to the lower cushioning material 130. In this case, in the height direction of the lower cushioning material 130, the lower side of the common groove is the second curved portion 136b of the universal tube holding portion 136, and the upper side of the common groove is the intermediate curved portion 138b of the insertion portion holding portion 138. It is.

  Therefore, the intermediate portion of the insertion portion 220 of the endoscope 200 can be accommodated and held on the universal tube 230 of the endoscope 200 held by the second bending portion 136b of the universal tube holding portion 136. it can. In addition, an intermediate portion of the insertion portion 220 of the endoscope 200 is overlaid on the universal tube 230 that is stored so as to intersect with the upper portion of the operation portion 210 of the endoscope 200, and above the operation portion 210 of the endoscope 200. Can be housed and held in a cross.

  Thereafter, the distal end portion of the insertion portion 220 of the endoscope 200 is further accommodated in the front straight portion 138c of the holding portion 131 of the lower cushioning material 130 shown in FIG. Here, as described above, the front straight portion 138c linearly extends rearward and diagonally rightward toward the right side surface of the lower cushioning material 130 along the laterally extending portion 135a of the operation portion holding portion 135. Crosses the portion 138a. Further, in the height direction of the lower cushioning material 130, the depth of the front straight portion 138c is greater than the depth of the rear curved portion 138a at the front end portion in the vicinity of the right side surface of the lower cushioning material 130 that intersects the rear curved portion 138a. It is shallow. Furthermore, the front straight portion 138c can be inclined at the bottom so that the depth in the height direction of the lower cushioning material 130 gradually decreases from the connecting portion with the intermediate curved portion 138b toward the tip.

  Accordingly, the distal end portion of the insertion portion 220 of the endoscope 200 can be stored by crossing the proximal end portion close to the operation portion 210, and the distal end portion of the insertion portion 220 of the endoscope 200 can be stored in the lower portion. It can arrange | position in the vicinity of the upper surface 130a of the buffer material 130, and can take out easily. Further, the distal end portion of the endoscope 200 can be accommodated and held linearly. With the above procedure, the endoscope 200 can be accommodated and held in the holding portion 131 of the lower cushioning material 130. Note that the endoscope 200 accommodated and held in the holding portion 131 of the lower cushioning material 130 can be taken out by a procedure reverse to the above procedure.

  Next, as shown in FIG. 7, the upper cushioning material 140 is accommodated in the outer box 110 from the opening 110 a of the outer box 110 and placed on the lower cushioning material 130. Here, the upper cushioning material 140 is provided so as to cover the entire upper surface 130 a of the lower cushioning material 130 including the holding portion 131. In other words, the upper cushioning material 140 does not have a notch or a through hole that is continuous from the lower end to the upper end of the upper cushioning material 140 so as to expose the upper surface 130a of the lower cushioning material 130 or a part of the holding portion 131. Thereby, it is possible to prevent dust and dust from entering between the lower cushioning material 130 and the upper cushioning material 140.

  For example, when the upper cushioning material 140 does not cover the upper surface 130 a of the lower cushioning material 130 or a part of the holding portion 131, dust or dust collects on the upper surface 130 a of the lower cushioning material 130 or the concave holding portion 131. There is a risk of dust and dust entering. In this case, for example, when the upper cushioning material 140 is taken out, dust or dust collected on the upper surface 130 a of the lower cushioning material 130 may fall on the concave holding portion 131 and adhere to the endoscope 200. However, by covering the entire upper surface 130a of the lower cushioning material 130 including the holding portion 131 with the upper cushioning material 140, such a problem can be solved.

  Therefore, according to the endoscope case 100 of the present embodiment, dust and dust adhere to the endoscope 200 that is held by the holding portion 131 provided in the lower cushioning material 130 and covered by the upper cushioning material 140. Can be effectively prevented.

  Furthermore, in the endoscope case 100 of the present embodiment, the upper cushioning material 140 has recesses 141a, 141b, and 141c at positions corresponding to the holding portions 131 of the lower surface 140b facing the lower cushioning material 130.

Interference with 140 can be avoided.

  Thereby, the dust generation by contact with the upper shock absorbing material 140 and an endoscope can be prevented. In addition, since a part of the endoscope 200 accommodated in the holding portion 131 of the lower cushioning material 130 can be protruded toward the upper cushioning material 140, the depth of the holding portion 131 of the lower cushioning material 130 is made more than necessary. There is no need to deepen. Thereby, the lower buffer material 130 can be thinned. In addition, the endoscope 200 can be easily taken out from the holding portion 131 of the lower cushioning material 130.

  More specifically, in the endoscope case 100 of the present embodiment, the holding unit 131 of the lower cushioning material 130 has an operation unit holding unit 135 that holds the operation unit 210 of the endoscope 200. Further, the concave portions 141 a and 141 b of the upper cushioning material 140 are opposed to the operation unit holding unit 135. Accordingly, it is possible to avoid interference between the protruding portion of the operation unit 210 and the upper cushioning material 140 such as the up / down bending operation lever 211 and the left / right bending operation lever 212 of the operation unit 210 of the endoscope 200.

  In the endoscope case 100 of the present embodiment, the holding part 131 of the lower cushioning material 130 has a connector part holding part 137 that holds the connector part 240 of the endoscope 200. The concave portion 141c of the upper cushioning material 140 faces the connector portion holding portion 137. Thereby, interference with the protruding part of the connector part 240, such as the air / water supply base 243 of the connector part 240 of the endoscope 200, and the upper cushioning material 140 can be avoided.

  Furthermore, in the endoscope case 100 of the present embodiment, the upper cushioning material 140 is configured such that the thickness of the portion facing the operation portion holding portion 135 is larger than the thickness of the portion facing the connector portion holding portion 137. The depth of the concave portion 141 a facing the holding portion 135 is made deeper than the depth of the concave portion 141 c facing the connector portion holding portion 137. Accordingly, the up / down bending operation lever 211 and the left / right bending operation lever 212 of the operation unit 210 that is likely to be the most protruding portion in the endoscope 200 are formed in the deep concave portion 141a of the portion where the thickness of the upper cushioning material 140 is increased. It is possible to avoid the interference between the protruding portion of the operation unit 210 and the upper cushioning material 140 by being accommodated.

  Therefore, it is not necessary to form an opening for avoiding interference with the endoscope 200 in the upper cushioning material 140, and the upper cushioning material 140 covers the entire upper surface 130a including the holding portion 131 of the lower cushioning material 130. It becomes possible. Furthermore, in the endoscope 200, a part of the connector part 240 whose protrusion height is likely to be lower than that of the operation part 210 is accommodated in the shallow concave part 141c of the part where the thickness of the upper cushioning material 140 is reduced, and the connector part Interference between the protruding portion 240 and the upper cushioning material 140 can be avoided. Therefore, it is possible to avoid the upper cushioning material 140 from becoming thicker than necessary.

Further, unlike the case of forming a notch-shaped handle portion continuous from the lower surface 140b of the upper cushioning material 140 to the upper surface 140a, the upper cushioning material 140 does not expose the upper surface 130a of the lower cushioning material 130. The entire upper surface 130a of the material 130 can be covered.

  Further, in the endoscope case 100 of the present embodiment, the outer box 110 has a handle 115 attached to the side wall 112. The lower cushioning material 130 has a notch 134 at a position corresponding to the handle 115. The upper cushioning material 140 has a stepped portion 147 at a position corresponding to the handle 115. The step portion 147 of the upper cushioning material 140 is disposed on the cutout portion 134 of the lower cushioning material 130. Thereby, the handle 115 can be held and carried when carrying the endoscope case 100, and the carrying of the endoscope case 100 can be facilitated.

The water supply tube and the air supply tube are configured so that the flow rate of the fluid flowing inside can be adjusted by the operation of the air / water supply button 213 of the operation unit 210.

(Endoscope system)
Finally, an example of an endoscope system 300 including the above-described endoscope 200 housed in the endoscope case 100 of the present embodiment will be described in detail.

  The endoscope system 300 includes, for example, an endoscope 200, a processor 310, and a monitor 320. In the endoscope 200, for example, a connector part 240 is connected to a connection part of the processor 310. As a result, the image processing connection sleeve 241 and the light source connection sleeve 242 projecting from the connector portion 240 of the endoscope 200 are connected to an image processing circuit, a light source, or the like built in the processor 310.

  In the endoscope 200, for example, an air / water supply pipe connected to a fluid supply source for supplying air and water (not shown) is connected to the air / water supply base 243 of the connector 240. The monitor 320 is an image display device such as a liquid crystal display device, and is connected to the processor 310. The processor 310 includes, for example, a main switch 311, a lighting switch 312, and an image changeover switch 313.

  The endoscope system 300 having such a configuration can be used, for example, according to the following procedure. First, the main switch 311 is pressed to be turned on, the illumination switch 312 is pressed to be turned on, and the image switching switch 313 is switched to the first switching position. When the illumination switch 312 is turned on, the light source in the processor 310 emits light.

The light emitted from the light source in the processor 310 is introduced into the light guide fiber through the light source connection sleeve 242 of the connector part 240 of the endoscope 200 connected to the processor 310. The light from the light source introduced into the light guide fiber passes through the universal tube 230, the operation unit 210, and the light guide fiber passed through the insertion unit 220, and the illumination lens on the front end surface of the connection unit 222 and the hard tip portion It reaches the illumination lens on the front end surface of 224 and is irradiated forward.
When the main switch 311 is turned on, the image sensor in the connection part 222 of the endoscope 200 and the image sensor in the distal end hard part 224 are activated. As a result, the image of the subject located in front of the objective lens on the front end surface of the connection portion 222 and the front end surface of the distal end hard portion 224 of the endoscope 200 is converted into an objective lens and a plurality of objective lenses inside the connection portion 222 and the distal end hard portion 224. Photographed by the image sensor through the lens. Image data of a subject image photographed by the image sensor is sent to an image processing circuit in the processor 310 via an image signal cable passed through the insertion unit 220, the operation unit 210, and the universal tube 230. Image processing is performed by the image processing circuit.

  The processor 310 generates first image processing data based on image data captured by the image sensor in the connection unit 222 of the endoscope 200, and is imaged by the image sensor in the distal end hard portion 224 of the endoscope 200. Second image processing data is generated based on the obtained image data. The processor 310 sends the first image processing data to the monitor 320 when the image changeover switch 313 is at the first changeover position, and sends the second image processing to the monitor 320 when the image changeover switch 313 is at the second changeover position. Send data. Thereby, the image to be displayed on the monitor 320 can be switched between a front image of the connecting portion 222 of the endoscope 200 and an image of the front of the distal end hard portion 224 of the endoscope 200.

  Further, when the air escape hole formed on the upper surface of the air / water supply button 213 of the operation unit 210 of the endoscope 200 is closed, the compressed air supplied from the fluid supply source is supplied to the front end surface of the distal end hard portion 224.
