A structure in which a holder is coupled to a cartridge-type replaceable blade housed in a case and pulled out is known. In addition, when the orientation of the holder to which the spare blade stored in the case is to be joined is inappropriate, for example, when the holder is reversed, the holder approaches the spare blade. The structure which interrupts | blocks is also well-known (for example, refer patent document 1).
JP-T-2001-512351

  The present invention prevents the holder from approaching the replaceable blade when the orientation of the holder to which the replaceable blade stored in the case is to be combined is inappropriate. The challenge is to make it recognized immediately.

  Patent Document 1 is a configuration in which a replaceable blade is housed between a front inclined divider and a rear inclined divider in a case, and the handle connecting structure of the handle is connected to the replaceable blade connected structure of the replaceable blade. The replacement blade is connected to the handle by moving it along. In addition, the handle is provided with a blocking structure that is asymmetric with respect to the connecting shaft, and when the handle is in an improper direction, the blocking structure comes to the side adjacent to the rear tilt divider and the rear tilt divider Blocked. When the handle is in the proper orientation, the blocking structure on the handle can be moved away from the rear tilt divider so that it can be passed over the rear tilt divider.

In Patent Document 1, the blocking structure provided on the handle is a button of the handle. When the handle is in an inappropriate direction, the button hits the backward inclined divider, and the handle connection structure of the handle and the replaceable blade connection structure of the replaceable blade are not aligned. Therefore, the handle connection structure cannot be inserted into the replaceable blade connection structure, and the two are not connected. That is, since the handle connection structure does not move correctly along the connection axis with respect to the replaceable blade connection structure, the handle connection structure is not inserted into the replaceable blade connection structure and the two are not connected.

  In Patent Document 1, the handle connection structure cannot be connected without being inserted into the replaceable blade connection structure. However, when the rear end of the handle is slightly lifted from the connection shaft, the handle connection structure comes into contact with the replaceable blade connection structure. It is the structure which can move to. However, since the handle connection structure is inclined with respect to the connection axis, it is not inserted into the replaceable blade connection structure, but the handle connection structure can be connected to the replaceable blade even if the rear end of the handle is not lifted unnaturally. It touches the structure. Thus, since the handle connection structure can easily reach the replaceable blade connection structure even if the handle is in an inappropriate direction, Patent Document 1 does not immediately recognize that the handle is inappropriate, Can also try to insert. Therefore, the present invention blocks the approach of the holder to the replacement blade when the direction of the holder to which the replacement blade stored in the case is to be combined is inappropriate, and further indicates that the direction is inappropriate. The purpose is to make the user recognize immediately.

Claim 1 of the present invention is a case for storing a cartridge type replaceable blade that can be replaceably attached to a holder having a predetermined structure, and the holder is for connecting the replaceable blade to the upper part thereof. The replacement blade has a connection structure for connecting with the connection portion of the holder, the case is provided with at least one storage chamber, and the storage chamber has an opening at the upper side in the longitudinal direction. A locking means for fixing the replaceable blade to the storage chamber in a state surrounded by a pair of side walls extending in the direction and a pair of end walls at both ends thereof and having a bottom portion, with the connecting structure of the replaceable blade facing the open port side Is provided in the storage chamber, and when the replaceable blade of the storage chamber is connected to the holder and pulled out, the connecting portion of the holder is connected to the connecting structure of the replaceable blade, and the replaceable blade is pulled out. When the orientation of the holder is inappropriate When the holder coupling portion is brought closer to the replacement blade coupling structure, a protrusion for blocking the coupling between the coupling portion and the coupling structure is provided on one of the holder or the case, and There is a blocking part that hits the protrusion, and when the protrusion is on the holder, it protrudes in the mounting direction when installing the replacement blade, and when the protrusion is on the case, it protrudes in the opposite direction. In addition, the protrusion and the blocking portion cooperate to prevent the coupling portion and the coupling structure from approaching a certain level, and the coupling is blocked.

According to a second aspect of the present invention, when the orientation of the holder when joining the replaceable blade is appropriate, the replaceable blade passes through the coupling center of the holder and the replaceable blade when trying to bring the holder coupling portion closer to the joint structure of the replaceable blade. Centering on the connecting line extending in the longitudinal direction, the protrusion and the blocking part are biased to different sides so that they do not touch each other, and the holder connecting part when connecting the replaceable blade is inappropriate An element added to claim 1 is an element in which the blocking portion and the projecting portion are biased to the same side of the connecting line when they are brought closer to the connecting structure of the replaceable blade.

According to a third aspect of the present invention, a pair of arms is provided on the upper part of the holder, and a pair of coupling parts are provided on the tips of these arms, respectively, and the protrusion is provided on the holder, and the upper part of the holder is connected to The pusher that pushes the replacement blade from the bottom is the protrusion, and when the orientation of the holder when connecting the blades is appropriate, the engagement portion that engages with this pusher is formed on the replacement blade Is a configuration added to claim 1 or claim 2.

According to a fourth aspect of the present invention, the flange extends along the upper end of one side wall of the storage chamber, both ends of the flange are not connected to the end wall, and the blocking portion is present in the center portion of the flange as a component part of the flange. These elements are added to claim 2 or claim 3.

According to a fifth aspect of the present invention, when the replaceable blade is stored in the storage chamber, a recess is formed in the flange for exposing all or part of the connecting structure of the replaceable blade, and the outer peripheral line of the flange constituting the recess is stored. An element aligned with the outer peripheral line of the connecting structure of the replaceable blade is added to claim 4.

Claim 6 is a case for storing a cartridge-type replaceable blade that can be replaceably attached to a holder having a predetermined structure, and the holder has a coupling portion for coupling the replaceable blade on the upper portion thereof. The replacement blade has a coupling structure coupled to the coupling portion of the holder, the case is provided with at least one storage chamber, and the storage chamber has a pair of openings and extends in the longitudinal direction. The storage chamber is provided with a locking means for fixing the replaceable blade to the storage chamber in a state surrounded by the side wall and a pair of end walls at both ends thereof and having a bottom portion, and the connecting structure of the replaceable blade faces the opening side. When the replacement blade of the storage chamber is coupled to the holder and pulled out, the coupling portion of the holder is coupled to the coupling structure of the replacement blade, and the replacement blade is pulled out. If the orientation of the holder is inappropriate, When trying to bring the connecting part of the der closer to the connecting structure of the replaceable blade, the blocking part for blocking the connection between the connecting part and the connecting structure is directed from the upper end of one side wall of the storage chamber toward the opposite side wall. It is the structure which protrudes in parallel with the bottom part of a storage chamber.

According to the first aspect of the present invention, a protrusion for blocking the coupling between the coupling portion and the coupling structure is provided on one of the holder and the case, and a blocking portion on which the projection abuts is provided on the other. In some cases, it protrudes in the mounting direction when the replacement blade is mounted, and in the case where the protrusion is in the case, it protrudes in the opposite direction. In this configuration, the coupling structure does not approach a certain level and the coupling is blocked. When the protrusion for blocking is on the holder, it protrudes in the mounting direction when the replacement blade is mounted, and when the protrusion is on the case, it protrudes in the opposite direction. Unlike Patent Document 1, Claim 1 is a configuration in which the holder is moved along the mounting direction even when the direction of the holder is inappropriate, and a protrusion facing the mounting direction or the opposite direction hits the blocking portion. It cannot be moved any further and is blocked. For this reason, there exists a space | interval only the height of a protrusion between a coupling | bond part and a coupling structure, and they do not contact. The user can immediately recognize that it is impossible to contact the coupling portion and the coupling structure by looking at it, so that it is possible to immediately recognize that the orientation of the holder is inappropriate.

According to a second aspect of the present invention, when the orientation of the holder when joining the replaceable blade is appropriate, the replaceable blade passes through the coupling center of the holder and the replaceable blade when trying to bring the holder coupling portion closer to the joint structure of the replaceable blade. Centering on the connecting line extending in the longitudinal direction, the protrusion and the blocking part are biased to different sides so that they do not touch each other, and the holder connecting part is not suitable when the replacement blade is connected in an inappropriate direction. When approaching the joint structure of a replaceable blade, the blocking part and the protrusion are biased to the same side of the joint line so that the two hit each other. If the orientation of the holder when joining the blades is inappropriate, the blocking part and the protrusion are on the same side of the connecting line, so it is obvious that both hits before the protruding part hits the blocking part. is there. Therefore, the direction of the holder can be made appropriate without bothering the user.

According to a third aspect of the present invention, a pair of arms are provided on the upper part of the holder, and a pair of coupling parts are provided on the tips of these arms, and a protrusion is provided on the holder, between the upper part of the holder and the arms. The pusher that pushes the replacement blade from below is the protrusion, and the engagement portion that engages with the pusher is formed on the replacement blade when the direction of the holder when connecting the blades is appropriate. The pusher is a component that is attached to the holder mainly to elastically support the replacement blade from below. For example, it is attached to a swing-type safety razor. The swing-type safety razor is attached to the holder so that the replacement blade can swing around a swing axis extending in the longitudinal direction. Then, the pusher elastically presses the engaging portion of the replaceable blade, so that the swung replaceable blade is naturally returned to the original position. As described above, normally, the replacement blade is used as a protrusion for blocking the pusher that is supported by pushing from the bottom, so that the structure can be simplified and the cost can be reduced by effectively using one component.

According to a fourth aspect of the present invention, the flange extends along the upper end of one side wall of the storage chamber, both ends of the flange are not connected to the end wall, and the blocking portion is present at the center of the flange as a component part of the flange. It is the composition which is. Since the blocking portion is a component part of the flange, the strength of the blocking portion is equal to that of the flange and increases. Therefore, even if the projecting portion for blocking hits the blocking portion, the blocking portion is not deformed or damaged. Further, since the flange extends along the upper end of the side wall, the replaceable blade housed by the flange itself or a rib provided on the bottom surface of the flange can be pressed. Thereby, since the flange fulfills two actions of a blocking action and a pressing action of the replacement blade, the configuration can be simplified and the cost can be reduced accordingly.

According to a fifth aspect of the present invention, when the replaceable blade is stored in the storage chamber, a recess is formed in the flange for exposing all or part of the connecting structure of the replaceable blade, and the outer peripheral line of the flange constituting the recess is stored. It is aligned with the outer circumference of the connecting structure of the blade. Since the connecting portion is provided at the tip of the arm, the connecting portion can be automatically matched to the connecting structure of the replaceable blade by connecting the tip of the arm to the concave portion of the flange. Thereby, the operation | work which couple | bonds a replaceable blade with a holder becomes smooth.

According to a sixth aspect of the present invention, when the orientation of the holder when coupling the replaceable blade is inappropriate, when the coupling portion of the holder is brought close to the coupling structure of the replaceable blade, the coupling portion and the coupling structure are coupled. The blocking portion to be blocked projects from the upper end of one side wall of the storage chamber so as to extend in parallel with the bottom toward the other opposite side wall. As a result, when the direction of the holder when connecting the replaceable blade is inappropriate, the user extends the element blocking the connection between the connecting portion and the connecting structure from the upper end of the side wall toward the other side wall. It can be understood at a glance that it is a blocking part. Therefore, the holder can be immediately changed to an appropriate direction without repeating trial and error. Moreover, since the stored replacement blade can be pressed and fixed from above using the blocking part, the blocking part has two actions. Thereby, the structure can be simplified and the cost can be suppressed.

  Next, the best mode for carrying out the present invention will be described. The safety razor in this embodiment is a so-called swinging type, and the replaceable blade 1 is attached to the holder 2 so as to be swingable about a swing axis extending in the longitudinal direction. Note that the safety razor used in the present invention is not limited to the swing-type razor, as long as the replaceable blade can be detachably mounted. It may not be.

  First, a configuration in which the replaceable blade 1 is swingably attached to the holder 2 will be described. FIG. 6 shows a replaceable blade coupling mechanism at the top of the holder 2. FIG. 6 shows a state in which the arms 3 and 3 are closed and before the replacement blade 1 is attached. When the replaceable blade 1 is attached to the arms 3 and 3, the arms 3 and 3 are opened on both sides and coupled to the replaceable blade 1 as shown in FIG. As shown in FIG. 6, the arms 3 and 3 have bases 4 and 4 coupled to a shaft 5 so as to be rotatable. The replaceable blade coupling mechanism has a sliding member 7. FIG. 6 shows a state in which the sliding member is located in the forefront of the sliding range. The sliding member 7 is formed integrally with the push button 6 shown in FIG. A pusher pressing portion 8 is integrally formed in front of the sliding member 7. Therefore, as shown in FIG. 7, when the sliding member 7 is fully retracted as shown in FIG. 7, when the push button 6 is pressed, the sliding member 7 slides forward, and at the same time, the pusher pressing portion 8 is also integrated. And both move forward together.

  As described above, FIG. 6 shows a state in which the arms 3 and 3 are closed and before the replacement blade 1 is attached. In this state, the pusher 9 is pressed and fixed by the pusher pressing portion 8. The pusher 9 does not move back into the holder 2 unless the tip of the pusher 9 is pressed with a certain amount of force. The reason why the pusher 9 does not move backward unless the pusher 9 is fixed and pressed is that the protrusions 10 and 10 provided on both elastic portions 16 and 16 of the pusher pressing portion 8 are locked to the locking recesses 11 and 11 of the holder. It is. This means that the sliding member 7 is also fixed at the same time. And since the side pressure parts 12 and 12 provided in the sliding member 7 press the notch recessed parts 13 and 13 provided in the arm base parts 4 and 4 from the outside to the inside, both the arms 3 and 3 are closed. It is fixed in the state.

  FIG. 7 shows a state where the replaceable blade 1 is attached to the holder 2. The operation of connecting the replaceable blade 1 by opening the arms 3 and 3 as shown in FIG. 7 from the state in which the arms 3 and 3 are closed will be described. First, the tip of the pusher 9 is directed to the engaging portion 14 of the replaceable blade 1 and the holder 2 is strongly pressed. Then, the rear end inclined surfaces 15 and 15 of the pusher 9 press both elastic portions 16 and 16 of the pusher pressing portion 8 inward, and the locking state between the projections 10 and 10 and the locking recesses 11 and 11 is released. Then, the pusher 9 moves backward together with the pusher pressing portion 8 and the sliding member 7 integrated therewith. Moreover, the pressure parts 12 and 12 on both sides of the sliding member 7 are also retracted and detached from the notches 13 and 13. The rear end portion 17 of the pusher pressing portion 8 hits the jaw portions 18 and 18 of the arms 3 and 3 to push the arms 3 and 3 open. When the arms 3 and 3 are opened, the journal shafts 19 and 19 provided at the tips of the arms 3 and 3 are coupled to the journal bearings 20 and 20 of the replaceable blade 1 so that the replaceable blade 1 is swingably attached. At this time, since the pusher pressing portion 8 that pushes and opens the arms 3 and 3 is elastically pressed by the coil spring 21, the arms 3 and 3 are supported in an open state. The pusher 9 elastically presses the engaging portion 14.

When the replaceable blade 1 is removed from the holder 2, the sliding member 7 moves forward by pushing the push button 6 forward from the state shown in FIG. 7 where the replaceable blade 1 is coupled to the holder 2, and the pusher integrated therewith The pressing part 8 presses the pusher 9. At the same time, the lateral pressure portions 12 and 12 of the sliding member 7 hit the notch recesses 13 and 13 and press the notch portions 13 and 13 inward from the outside to close both arms 3 and 3. When both arms 3 and 3 are closed, the journal shafts 19 and 19 come out of the journal bearings 20 and 20 and the replaceable blade 1 is detached. The above is the configuration and operation in which the replaceable blade 1 is swingably attached to the holder 2.

  The replaceable blade coupling mechanism of the holder 2 shown in FIGS. 6 and 7 is configured as described above. As shown in FIG. 8, the holder 2 is provided with a head 23 having a replaceable blade coupling mechanism at the upper end of an elongated handle 22. As described above, the arms 3 and 3 are attached to the head 23. Journal shafts 19, 19 provided at the tips of arms 3, 3 are journal-coupled to journal bearings 20, 20 of replaceable blade 1, and replaceable blade 1 is attached to holder 2. Further, when the direction in which the cutting edge 58 of each replaceable blade 1 stored in FIG. 5 faces is the front of the case 27 and the opposite direction is the rear, the pusher 9 is against the straight line connecting both journal shafts 19, 19. It is shifted backward (right side in FIG. 5).

  As shown in FIG. 7, the replaceable blade 1 is provided with a pair of coupling structures 24, 24 at the bottom thereof. The coupling structures 24 and 24 include concave portions 25 and 25 provided at the bottom of the replaceable blade 1 and journal bearings 20 and 20 communicating with the concave portions 25 and 25. The ends of the closed arms 3 and 3 first enter the recesses 25 and 25, and then when the arms 3 and 3 are opened as shown in FIG. 7, the journal shafts 19 and 19 are journal bearings 20 and 20 respectively. to go into. By this journal coupling, the replaceable blade 1 can swing around the journal axis. The surface of the engaging portion 14 provided at the bottom of the replaceable blade 1 is formed on the cam surface 26. As shown in FIG. 1, the cam surface 26 is shifted rearward with respect to a straight line connecting both the coupling structures 24, 24 of the replaceable blade 1. The replaceable blade 1 oscillated in cooperation with the elastically pressing pusher 9 and the cam surface 26 is returned to the original position.

  As shown in FIGS. 1 to 5, the case 27 has four storage chambers. The case 27 is integrally formed of a transparent plastic. On the front side of the storage chamber 28, a front side wall 29 adjacent to the front side which is the cutting edge side of the stored replaceable blade 1 rises vertically from the bottom 31. A rear side wall 30 facing the front side wall 29 rises vertically from the bottom 31. The front side wall 29 and the rear side wall 30 surround the front and rear of the storage chamber 28. In addition, both end portions of each storage chamber 28 surround the storage chamber 28 with end walls 32 and 32 rising vertically from the bottom 31. The end walls 32 on the same side of all the storage chambers including the storage chamber 28 are integrally connected to form long outer peripheral walls 33, 33 of the case 27, respectively. In addition, the code | symbol 55 is a long hole provided in the bottom part of each storage chamber, and is for drying the upper surface of the replaceable blade 1 which has faced the bottom part. Reference numeral 57 denotes a small hole provided at the bottom of each storage chamber for drying the upper surface of the replaceable blade 1 facing the bottom. Reference numeral 56 is a reinforcing rib that reinforces the lower portion of each side wall.

  Both ends of the rear side wall 30 are not connected to the end walls 32, 32. Locking pieces 34, 34 rise from the bottom 31 between both ends of the rear side wall 30 and the end walls 32, 32. Grooves 35, 35 are provided between both ends of the rear side wall 30 and the locking pieces 34, 34. In addition, although the code | symbol is not attached | subjected to a figure, the groove | channel is also provided between the locking pieces 34 and 34 and the end walls 32 and 32. FIG. The locking pieces 34, 34 are elastically bent by grooves on both sides thereof. Locking protrusions 36, 36 facing the front side wall 29 are integrally provided on the upper portions of the locking pieces 34, 34. The locking projections 36 and 36 are locked to the rear part of the replaceable blade 1 housed as shown in FIG. 5 to prevent the replaceable blade 1 from coming out. When the replaceable blade 1 is put in and out, the locking pieces 34 and 34 are bent to allow the put-in and take-out.

Similarly to the rear side wall 30, both ends of the front side wall 29 are not connected to the end walls 32, 32. Locking pieces 38, 38 rise from the bottom 31 between both ends of the front side wall 29 and the end walls 32, 32. Grooves 46, 46 are provided between both ends of the front side wall 29 and the locking pieces 38, 38. Locking protrusions 39 and 39 are integrally formed on the locking pieces 38 and 38 so as to face the same direction as the locking protrusions 36 and 36. A flange 37 projects integrally from the upper end of the front side wall 29 toward the rear side wall 30. The flange 37 extends over the entire length of the front side wall 29. The flange 37 projects in parallel with the bottom 31. The edge of the flange 37 has a concave arc shape near its center. The vicinity of the center functions as a blocking unit 40 described later. In each side wall, there are five in total, two of the outermost side walls and three of the partitioning side walls between them, and all three partitioning side walls between the two outermost side walls have the same configuration. There is no equivalent to the locking piece 34 on the foremost side wall 44. This is because there is no storage room before that and it is unnecessary. There is no equivalent to the flange 37 on the rearmost side wall 45. This is because there is no storage room behind it and it is unnecessary.

  As shown in FIG. 3, a rib 41 is integrally provided from the inner surface of the front side wall 29 to the lower surface of the flange 37. A single front side wall 29 is provided with a pair of ribs 41, 41. Further, a replaceable blade support portion 42 that is connected to the bottom portion 31 is integrally provided on the inner surfaces of the both end walls 32, 32. The replaceable blade 1 is supported in a state of floating from the bottom 31 by the replaceable blade support portion 42. Therefore, there is an effect that the blade edge 58 of the blade body does not contact the bottom 31 or the like. The other three replaceable blades 1 except for the leftmost replaceable blade in FIG. 5 are supported on the replaceable blade support portion 42 in a slightly oblique manner, and are locked by the locking protrusions 36 and the ribs 41 to be stored in the storage chamber 28. It is stored in. Although the front side wall 29 and the rear side wall 30 rise vertically from the bottom 31, the replacement blade is slightly inclined because the replacement blade 1 is in contact with the front and rear side walls 29, 30 as is apparent in FIG. 5. This is because it is in contact with the locking projection 36 provided on the locking piece 34 and the rib 41 provided on the front side wall 29. 5 shows a state immediately after the locking projection 36 is released when the leftmost replaceable blade 1 is coupled to the holder 2 and pulled out. Thus, the replaceable blade 1 is pulled out while rotating counterclockwise in FIG.

  As described above and as shown in FIG. 4, the edge of the flange 37 has a concave arc shape near the center thereof. Near the center is the blocking portion 40. The edge of the blocking portion 40 does not protrude beyond the straight line connecting the pair of coupling structures 24, 24 of the stored replaceable blade 1. The cam surface 26 is shifted rearward with respect to a straight line connecting the coupling structures 24, 24 of the replaceable blade 1. Therefore, the cam surface 26 of the stored replaceable blade 1 is exposed without being covered by the blocking portion 40. Further, as described above, and as shown in FIG. 5, the pusher 9 is shifted backward (right side in FIG. 5) with respect to the straight line connecting both journal shafts 19 and 19. This means that when the direction of the holder 2 is appropriate, the cam surface 26 and the pusher 9 are shifted to the same side, that is, the rear side of the case with respect to the journal axis, that is, the connecting axis of the replaceable blade 1 and the holder 2. Since the cam surface 26 is not covered with the blocking portion 40, the pusher 9 can be engaged with the cam surface 26 without being blocked by the blocking portion 40.

As shown in FIG. 4, recesses 43 are formed at the corners of both ends of the flange 37. When the replaceable blade 1 is stored with the coupling structures 24, 24 facing upward, the concave portions 25, 25 of the joint structure 24, 24 of the replaceable blade 1 are exposed in alignment with the concave portions 43, 43. Therefore, when the direction of the holder 2 is appropriate, if the tips of the arms 3 and 3 are aligned with the recesses 43 and 43, they can naturally enter the recesses 25 and 25, and the replaceable blade 1 can be easily coupled. FIG. 5 shows a case where the orientation of the holder 2 is appropriate. When the holder 2 is further advanced from this state, the arms 3 and 3 enter the recesses 25 and 25 of the coupling structure 24 and 24 of the replaceable blade 1 through the recesses 43 and 43. The tip of the pusher 9 comes into contact with the cam surface 26. When the holder 2 is further pushed, the pusher 9 is moved backward as described above, and the arms 3 and 3 are opened, so that the replaceable blade 1 is coupled to the holder 2. Therefore, when the holder 2 is rotated counterclockwise in FIG. 5, the replacement blade 1 is also rotated together with it. As a result of the turning, it can get over the locking projection 36 like the leftmost replaceable blade 1, and the replaceable blade 1 can pass through the flange 37 and be pulled out.

When the replaceable blade 1 is coupled to the holder 2, the direction of the holder 2 is inappropriate when the holder 2 is reversed and connected to the replaceable blade 1. When trying to bring the tips of the arms 3 and 3 closer to the connecting structures 24 and 24 of the replaceable blade 1, the holder 2 is reversed in the front and back directions, so that the pusher 9 is located in front of the connecting axis of the replaceable blade 1 and the holder 2. Shift. As a result, the pusher 9 hits the blocking portion 40 before the tips of the arms 3 and 3 enter the recesses 25 and 25 of the coupling structures 24 and 24, so that they cannot be coupled. Further, as described above, the pusher 9 is configured not to retreat into the holder 2 unless the tip thereof is pushed with a certain amount of force. Therefore, even if the pusher 9 hits the blocking portion 40, the pusher 9 is not easily retracted, and the tips of the arms 3 and 3 are reliably blocked from entering the recesses 25 and 25 of the coupling structures 24 and 24. If the pusher 9 is pushed with a strong force and retracted into the holder 2, the arms 3 and 3 are opened as described above, so that the coupling becomes impossible at all.

FIG. 9 is a view showing a state in which the holder 2 combined with the replaceable blade 1 is mounted on the tray 47. The neck portion 48 of the holder 2 is clamped by the clamping portion 49 of the tray 47. The rear end portion 50 of the holder 2 is supported from below by the support base portion 51 of the tray 47. FIG. 10 is a view of FIG. 9 viewed from the bottom. Four claw portions 52 for holding the case 27 are provided on the bottom surface of the tray 47. The four claws 52 are engaged with the edges of the short outer peripheral walls 53 and 53 of the case 27 to hold the case 27 on the bottom of the tray 47. The case 27 is detachable from the tray 47. Reference numeral 54 is a drain hole, and this portion is low, and water dropped from the replaceable blade 1 attached to the holder 2 is collected here and discharged. In addition, the length of the short outer peripheral wall 53 of the case 27 is about 43 mm, the length of the long outer peripheral wall 33 is about 73 mm, and the height of the case 27 is about 11 mm. As shown in FIG. 2, the case 27 is provided with a symbol indicated by an arrow 59. This indicates that the direction of the holder 2 is appropriate if the upper end of the holder 2 is directed in the direction of the arrow when the replaceable blade 1 is coupled to the holder 2. Further, it is shown that it is appropriate to set the case 27 on the tray 47 so that the arrow 59 faces the upper end direction of the holder 2 set on the tray 27.
