  In the conventional endoscope storage case described in Patent Document 1, it is complicated to take out and store the endoscope scope. For example, when taking out the endoscope scope, the inner box-shaped upper cushioning material and lower cushioning material accommodated inside the case body are completely extracted from the opening on one side surface along the thickness direction of the flat case body. There is a need. Endoscope scope is finally obtained by arranging the upper cushioning material and lower cushioning material extracted from the case body so that the lower cushioning material is at the bottom, and removing the upper cushioning material covering the upper part of the lower cushioning material. Can be taken out.

  On the other hand, in the conventional endoscope storage case described in Patent Document 2, the case main body is arranged so that the case upper lid faces upward when the stored endoscope is taken out, and the front end side of the case upper lid is arranged. Lift up. As a result, the connecting portion between the rear end of the case upper lid and the case main body functions as a hinge, the case upper lid opens upward, and the endoscope can be taken out. Therefore, compared with the endoscope storage case described in Patent Document 1, the endoscope can be easily taken out, and the endoscope can be stored easily by the reverse procedure.

  However, in the cases described in Patent Document 1 and Patent Document 2, when the endoscope is housed, there is a possibility that a gap is generated between the cushioning material and the endoscope. When such a gap occurs, for example, when a vibration or impact is applied to the case, the endoscope moves inside the case, and the endoscope collides with or rubs against the cushioning material or the case body. There is a risk of problems such as obstacles and scratches.

  The present invention has been made in view of the above-described problems, and is an endoscope that is made of a simple material, can prevent a malfunction of the endoscope due to vibration or impact, and can be easily taken out and stored. The purpose is to provide a case.

An upper cushioning material disposed adjacent thereto, and an intermediate cushioning material disposed between the upper cushioning material and the lower cushioning material, wherein the lower cushioning material has a concave shape for holding the endoscope The intermediate cushioning material is accommodated in the holding portion, and the endoscope is held by the holding portion when the endoscope is held by the holding portion. Characterized in that it is disposed between the the endoscope upper cushioning material.

  The outer box and the cushioning material constituting the endoscope case of the present invention are each made up of corrugated cardboard and foamed resin, which are simple materials. Therefore, the endoscope case of the present invention can be reduced in weight, can be easily recycled, and the manufacturing cost can be suppressed.

  When the endoscope is housed in the endoscope case of the present invention, the endoscope case is arranged so that the bottom wall of the outer box is, for example, downward. Then, the upper lid that closes the opening of the outer box is opened by rotating upward using the connecting portion that connects one end of the upper lid and the side wall of the outer box as a hinge, thereby opening the opening of the outer box. Next, the upper cushioning material accommodated in the outer box and covering the entire upper surface of the lower cushioning material including the holding portion and the intermediate cushioning material accommodated in the lower cushioning material holding portion are taken out from the opening of the outer box.

  Next, the endoscope is accommodated in the outer box from the opening of the outer box, and the endoscope is disposed and held in the holding portion of the lower cushioning material accommodated in the outer box. The holding portion for the lower cushioning material is, for example, a recess or groove having a shape corresponding to the shape of each part of the endoscope that is recessed on the upper surface of the lower cushioning material. Next, an intermediate cushioning material having an appropriate size and shape corresponding to the dimension and shape of the holding part is accommodated in the holding part of the lower cushioning material so as to fill the gap above the endoscope held by the holding part. , Place it in an appropriate position.

  Next, the upper cushioning material is accommodated in the outer box through the opening of the outer box, the lower cushioning material is covered with the upper cushioning material, and the endoscope and the upper cushioning material held by the holding portion of the lower cushioning material In the meantime, hold the intermediate cushioning material. Next, the upper lid is rotated and closed using the connecting portion of the outer box as a hinge, and the opening of the outer box is closed by the upper lid. Thereby, the endoscope is accommodated between the lower cushioning material and the upper cushioning material made of foamed resin having excellent cushioning properties, and the gap between the endoscope and the upper cushioning material is filled with the intermediate cushioning material. The outside can be covered with a cardboard outer box having excellent durability.

  Therefore, for example, even if vibration or impact is applied to the endoscope case, the vibration or movement of the endoscope inside the endoscope case is suppressed, and collision and rubbing between the endoscope and the cushioning material are prevented. Occurrence of malfunctions such as endoscope malfunctions and scratches is prevented. Therefore, according to the endoscope case of the present invention, it is possible to prevent problems with the endoscope due to vibration and impact.

  When the endoscope housed in the endoscope case of the present invention is taken out, for example, the endoscope case is disposed so that the bottom wall of the outer box faces down, and a connecting portion between one end of the upper lid of the outer box and the side wall The upper lid is pivoted upward with the hinge as a hinge to open, and the opening of the outer box is opened. Next, the upper cushioning material accommodated in the outer box and covering the upper surface of the lower cushioning material including the holding portion is taken out from the opening of the outer box, and the intermediate cushioning material contained in the lower cushioning material holding portion is taken out. Thereby, it becomes possible to take out the endoscope held by the holding portion of the lower cushioning material.

  As described above, the endoscope case according to the present invention is configured by opening and closing the upper lid using the connecting portion of the outer box as a hinge, and only inserting and removing the upper cushioning material through the opening of the outer box. The endoscope can be taken out from the endoscope case by being housed in the case. Therefore, according to the endoscope case of the present invention, it is possible to facilitate storing and taking out the endoscope as compared with the conventional endoscope storing case described in Patent Document 1.

  The intermediate cushioning material may have a dimension in which a lower surface is in contact with the endoscope and an upper surface is in contact with a lower surface of the upper cushioning material in a state where the endoscope is held by the holding portion. Thereby, the endoscope is sandwiched and held between the bottom portion of the holding portion of the lower cushioning material and the lower surface of the intermediate cushioning material, and the endoscope is prevented from moving with respect to the lower cushioning material. Therefore, even if vibration or impact is applied to the endoscope case, the movement of the endoscope housed therein can be suppressed, and problems with the endoscope due to vibration or impact can be prevented.

  The intermediate cushioning material may have a size such that an upper end portion projects from an upper surface of the lower cushioning material in a state where the endoscope is held by the holding portion and an upper portion of the holding portion is opened. As a result, when the upper cushioning material is disposed on the lower cushioning material, the intermediate cushioning material is compressed and elastically deformed between the endoscope and the upper cushioning material, and the holding portion is transferred from the intermediate cushioning material to the endoscope. The elastic force acts toward the bottom of the. Therefore, the endoscope can be firmly held between the intermediate cushioning material and the bottom portion of the holding portion, and even if vibration or impact acts on the endoscope case, the endoscope held by the holding portion can be The movement can be suppressed, and the malfunction of the endoscope due to vibration or impact can be prevented.

  The elastic coefficient of the intermediate buffer material may be smaller than the elastic coefficients of the upper buffer material and the lower buffer material. Accordingly, the intermediate cushioning material can be easily elastically deformed, and when the upper cushioning material is disposed on the upper surface of the lower cushioning material, the intermediate cushioning material projects upward from the holding portion of the lower cushioning material, and the lower cushioning material It is possible to prevent a gap from being generated between the upper cushioning material and the upper cushioning material. For example, when the upper cushioning material is disposed on the upper surface of the lower cushioning material, the upper cushioning material projects from the upper surface of the lower cushioning material due to the load of the upper cushioning material acting on the upper surface of the intermediate cushioning material. The portion may have an elastic coefficient capable of elastically deforming up to the same height as the upper surface of the lower cushioning material.

  The intermediate cushioning material may be disposed on the operation portion of the endoscope in a state where the endoscope is held by the holding portion. The operation portion of the endoscope is formed with protruding portions such as various operation levers, operation buttons, and forceps openings. In order to avoid such interference between the protruding portion of the operation portion and the cushioning material, the holding portion of the lower cushioning material is formed in a shape and size that can accommodate the protruding portion of the operation portion. Then, when the upper cushioning material is disposed on the upper part of the lower cushioning material, a gap may be formed between the manipulation unit and the upper cushioning material in portions other than the projecting portion of the manipulation unit. Even in such a case, by arranging the intermediate cushioning material on the operation part of the endoscope, the gap between the operation part and the upper cushioning material can be filled with the intermediate cushioning material, and the vibration of the operation part and The movement can be effectively suppressed, and the malfunction of the operation unit can be suppressed.

  The holding portion has an operation portion holding portion for holding the operation portion of the endoscope, and the intermediate cushioning material has an outer size corresponding to an inner size of the operation portion holding portion, and holds the operation portion. You may make it fit in a part. Accordingly, in the operation unit holding unit that holds the operation unit of the endoscope having a complicated shape, the gap between the operation unit and the upper cushioning material can be more reliably filled with the intermediate cushioning material. Can be effectively suppressed.

  According to the present invention, it is possible to provide an endoscope case that is made of a simple material, can prevent malfunction of the endoscope due to vibration and impact, and can be easily taken out and stored.

And a connector portion 240 connected to the tube 230. An example of the endoscope 200 housed in the endoscope case 100 and held by the holding portion 131 of the lower cushioning material 130 will be described in detail later.

  The holding part 131 of the lower cushioning material 130 includes, for example, an operating part holding part 135, a universal part that accommodates and holds the operating part 210, the universal tube 230, the connector part 240, and the insertion part 220 of the endoscope 200, respectively. It has a tube holding part 136, a connector part holding part 137, and an insertion part holding part 138.

  The operation unit holding unit 135 is, for example, a generally L-shaped recess corresponding to the shape of the operation unit 210 of the endoscope 200. In the operation portion holding portion 135, a part of the longitudinal dimension of the laterally extending portion 135a extending along the lateral direction of the lower cushioning material 130 is slightly smaller than the dimension of the operation portion 210 of the endoscope 200 in the same direction. Has been made smaller. Accordingly, when the operation unit 210 of the endoscope 200 is accommodated in the operation unit holding unit 135, a part of the operation unit holding unit 135 is slightly elastically deformed, and a part of the operation unit 210 of the endoscope 200 is obtained. Can be clamped from both sides in the vertical direction.

  In addition, the operation unit holding unit 135 includes, for example, a recess 135c in which a part of the size in the vertical direction is larger than the size of the operation unit 210 of the endoscope 200 in the same direction. As a result, when the operation unit 210 of the endoscope 200 is accommodated in the operation unit holding unit 135, a gap is formed between the operation unit holding unit 135 and the operation unit 210 of the endoscope 200 by the recess 135c. The portion 210 can be easily taken out and stored.

  In the operation unit holding unit 135, for example, the horizontal dimension of the vertical extending part 135b extending along the vertical direction is slightly larger than the dimension of the operation unit 210 of the endoscope 200 in the same direction. Yes. Thereby, when the operation unit 210 of the endoscope 200 is accommodated in the operation unit holding unit 135, a slight gap is formed between the operation unit holding unit 135 and the operation unit 210 of the endoscope 200. It becomes easy to accommodate the operation unit 210 of the endoscope 200 in the operation unit holding unit 135.

  The universal tube holding portion 136 is, for example, a generally annular groove that is continuous with the longitudinally extending portion 135b of the operation portion holding portion 135, and includes a first bending portion 136a and a second bending portion 136b. 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.

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.

  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. 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 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 includes a rear bending portion 138a, an intermediate bending portion 138b, and a front straight portion. 138c. 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 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. 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.

  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. The front straight portion 138c may 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.

  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.

  The intermediate cushioning material 150 is accommodated in the holding portion 131 as shown in FIG. 3, for example, with the endoscope 200 being held in the holding portion 131 of the lower cushioning material 130 as shown in FIG. Further, the intermediate shock absorber 150 is disposed on the endoscope 200 held by the holding portion 131 of the lower shock absorber 130, and the upper shock absorber 140 shown in FIG. By arrange | positioning so that it may cover, it arrange | positions between the endoscope 200 and the upper shock absorbing material 140. FIG. In this state, the intermediate cushioning material 150 may have a dimension such that the lower surface 150b is in contact with the endoscope 200 and the upper surface 150a is in contact with the lower surface 140b of the upper cushioning material 140, for example.

  In addition, the intermediate cushioning material 150 has the upper end protruding from the upper surface 130a of the lower cushioning material 130 in a state where the endoscope 200 is retained by the retaining portion 131 of the lower cushioning material 130 and the upper portion of the retaining part 131 is opened. You may have the dimension to do. In this case, when appropriate elasticity is imparted to the intermediate cushioning material 150 and the upper cushioning material 140 is disposed on the upper surface 130a of the lower cushioning material 130, the lower surface 140b of the upper cushioning material 140 is disposed on the upper surface 150a of the intermediate cushioning material 150. The intermediate cushioning material 150 can be elastically deformed by the pressing force acting downward from the center.

  As a result, the lower surface 140b of the upper cushioning material 140 can be brought into contact with the upper surface 130a of the lower cushioning material 130. In addition, the intermediate cushioning material 150 is elastically deformed by being compressed vertically between the endoscope 200 and the upper cushioning material 140, and the lower surface 150b is in contact with the endoscope 200, and the upper surface 150a is the upper part. It will be in the state which contact | connected the lower surface 140b of the shock absorbing material 140. FIG. In this case, the elastic coefficient of the intermediate cushioning material 150 can be made smaller than that of the upper cushioning material 140 and the lower cushioning material 130.

  As shown in FIG. 4, the intermediate cushioning material 150 may be disposed on the operation unit 210 of the endoscope 200 with the endoscope 200 being held by the holding part 131 of the lower cushioning material 130. it can. More specifically, the intermediate cushioning material 150 is, for example, between the one end of the operation unit 210 where the up / down bending operation lever 211 and the left / right bending operation lever 212 are provided and the intermediate portion where the forceps port 214 is provided. , And can be disposed on an elongated portion that does not have a protruding portion between the protruding portions of the operation unit 210.

  As shown in FIG. 4, for example, when the operation unit 210 has a truncated cone shape that tapers toward the end to which the insertion unit 220 is connected, the lower surface 150 b of the intermediate cushioning material 150 in contact with the operation unit 210 is A concave curved surface corresponding to the surface shape of the operation unit 210 may be used. Thereby, the clearance gap between the lower surface 150b of the intermediate buffer material 150 and the surface of the operation part 210 can be decreased, and a contact area can be increased. Further, the upper surface 150 a of the intermediate cushioning material 150 may have a shape corresponding to the shape of the lower surface 140 b of the upper cushioning material 140 in contact with the intermediate cushioning material 150. For example, the intermediate cushioning material 150 may have a convex portion that fits into a concave portion formed on the lower surface 140b of the upper cushioning material 140 on the upper surface 150a.

  As described above, in the endoscope case 100 of the present embodiment, the holding unit 131 of the lower cushioning material 130 has the operation unit holding unit 135 that holds the operation unit 210 of the endoscope 200. In this case, the intermediate cushioning material 150 may have an outer dimension corresponding to the inner dimension of the operation unit holding unit 135 and may be fitted to the operation unit holding unit 135. Here, the intermediate cushioning material 150 is fitted into the operation portion holding portion 135, for example, not only when the intermediate cushioning material 150 fits into the operation portion holding portion 135 without a gap, but also with the outer dimensions of the intermediate cushioning material 150. This includes a case where there is a negative dimensional tolerance with respect to the inner dimension of the operation unit holding unit 135 and a slight gap is formed between the intermediate cushioning material 150 and the operation unit holding unit 135. Such a dimensional tolerance can be appropriately determined within a range in which the movement of the endoscope 200 can be prevented.

  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 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. Is open. 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.

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.

As a result, the intermediate cushioning material 150 is accommodated in the holding portion 131 of the lower cushioning material 130 and is placed between the endoscope 200 and the upper cushioning material 140.

  Next, the upper lid 113 is closed to close the opening 110a of the outer box 110. At this time, the second lid insertion portions 113b on both sides in the lateral direction of the upper lid 113 of the outer box 110 are inserted between the side wall 112 and the upper cushioning material 140 of the outer box 110, and the side wall 112, the upper cushioning material 140 and the lower cushioning material are inserted. It arrange | positions between the materials 130. FIG. Thereby, the clearance gap between the side wall 112 of the outer box 110 and the buffer material 120 can be decreased, and the relative movement of the buffer material 120 and the outer box 110 can be prevented. In addition, since a folded portion 112a extending downward inside the opening 110a is formed on the left and right side walls 112 of the outer box 110, the second lid insertion portion 113b of the upper lid 113 of the outer box 110 is formed by the folded portion 112a. It is possible to guide and smoothly insert between the side wall 112 of the outer box 110 and the upper cushioning material 140.

  Thereafter, the first lid insertion portions 113a on both lateral sides of the front end portion of the upper lid 113 are inserted into the gap between the outer portion and the inner portion of the pair of side walls 112 extending in the vertical direction on the front side of the outer box 110. . A handle 115 is passed through a through hole 116 at the center of the front end of the upper lid 113 constituting the outer portion of the front side wall 112 of the outer box 110, and the front end of the upper lid 113 extends laterally in front of the outer box 110.

Thereby, the engaging portion 117a on the outer surface of the inner side portion of the front side wall 112 and the engaging portion 117b on the inner surface of the outer side portion of the front side wall 112 are engaged with each other. As described above, the endoscope 200 can be stored in the endoscope case 100, and the endoscope 200 stored in the endoscope case 100 can be taken out by the reverse procedure.

  Thus, according to the endoscope case 100 of the present embodiment, the endoscope 200 is housed between the lower cushioning material 130 and the upper cushioning material 140 made of foamed resin, which have better cushioning properties than cardboard, Further, the outside can be covered with a cardboard outer box 110 having excellent durability. Therefore, the endoscope case 100 according to the present embodiment is superior to the conventional endoscope storage case described in Patent Document 2 in terms of cushioning necessary for protecting the endoscope 200, and vibration during transportation. It is possible to more effectively alleviate the impact and prevent the endoscope 200 from malfunctioning.

  Furthermore, in the endoscope case 100 of the present embodiment, as described above, the intermediate cushioning material 150 is accommodated in the holding portion 131 of the lower cushioning material 130 and is disposed between the endoscope 200 and the upper cushioning material 140. It is in the state. Thereby, the gap between the endoscope 200 and the upper cushioning material 140 can be filled with the intermediate cushioning material 150. As a result, even if vibration or impact is applied to the endoscope case 100, the vibration or movement of the endoscope 200 inside the endoscope case 100 is suppressed by the intermediate cushioning material 150, and the endoscope 200 and the buffer are buffered. The collision and rubbing of the material 120 is prevented, and the occurrence of malfunctions such as functional failure and scratches of the endoscope 200 is prevented. Therefore, according to the endoscope case 100 of the present embodiment, problems of the endoscope 200 due to vibration and impact can be more effectively prevented.

  Further, as described above, in the state where the endoscope 200 is held by the holding portion 131 of the lower cushioning material 130, the intermediate cushioning material 150 is in contact with the endoscope 200 and the upper surface 150 a is the upper cushioning material 140. The bottom surface 140b may be in contact with the bottom surface 140b. In this case, the endoscope 200 is sandwiched and held between the bottom portion of the holding portion 131 of the lower cushioning material 130 and the lower surface 150b of the intermediate cushioning material 150, and is prevented from moving relative to the lower cushioning material 130.

The upper end portion of the intermediate cushioning material 150 protruding from the upper surface 130 a may have an elastic coefficient that can be elastically deformed to the same height as the upper surface 130 a of the lower cushioning material 130. Thereby, it can prevent more reliably that a clearance gap produces between the lower buffer material 130 and the upper buffer material 140 as mentioned above.

  Further, as described above, the intermediate cushioning material 150 can be disposed on the operation unit 210 of the endoscope 200 in a state where the endoscope 200 is held by the holding part 131 of the lower cushioning material 130.

In order to avoid such interference between the protruding portion of the operation unit 210 and the cushioning material 120, the holding portion 131 of the lower cushioning material 130 has a concave shape that can accommodate the protruding portion of the operation unit 210. And a size larger than the size of the operation unit 210.

  Then, when the upper cushioning material 140 is disposed on the lower cushioning material 130, a gap is formed between the manipulation unit 210 and the upper cushioning material 140 in the portions other than the protruding portion of the manipulation unit 210. There is. In particular, for example, a portion between one end portion of the operation unit 210 where the up / down bending operation lever 211 and the left / right bending operation lever 212 are provided and an intermediate portion where the forceps port 214 is provided is a protruding portion of the operation unit 210. A gap is easily formed between the operation unit 210 and the upper cushioning material 140.

  Even in such a case, the intermediate cushioning material 150 is disposed in a portion where the gap on the operation unit 210 of the endoscope 200 is likely to be generated, so that the gap between the operation unit 210 and the upper cushioning material 140 can be reduced. 150 can be filled. Therefore, according to the endoscope case 100 of the present embodiment, the vibration and movement of the operation unit 210 can be effectively suppressed, and problems with the operation unit 210 can be suppressed.

The image data of the subject image captured by the image sensor is sent to the image processing circuit in the processor 310 via the 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. It is injected from the air supply nozzle onto the surface of the adjacent objective lens. Further, when the air / water supply button 213 is depressed while closing the air escape hole of the air / water supply button 213, the cleaning water supplied from the fluid supply source is supplied to the air / water supply nozzle via the water supply pipe, and the adjacent objective lens Sprayed on the surface.

  The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
