<How to assemble the wearing clip 3>
As shown in FIG. 5, the clip member 5 is disposed on the rear side of the main body 71 of the fixing member 7. The clip member 5 is approached toward the main body 71. The connecting portion 91 and the spherical portion 92 of the connecting portion 9 are inserted into the second groove 722 of the main body 71 from the rear side toward the front side. The spherical portion 92 protrudes forward with respect to the rear side surface of the main body portion 71, and the clip member 5 is disposed rearward with respect to the rear side surface of the main body portion 71. As described above, the diameter L22 of the second groove portion 722 (see FIG. 12) is slightly larger than the diameter L32 of the spherical portion 92 (see FIG. 7). Therefore, the insertion of the sphere 92 into the second groove 722 is not hindered.

  Next, an upward force is applied to the clip member 5. The clip member 5 tends to move upward with respect to the main body 71. Here, as described above, the diameter L32 of the spherical portion 92 is larger than the distance L21 between the first grooves 721 (see FIG. 12). Therefore, when the spherical portion 92 is to move upward, the first groove portion 721 is elastically deformed by receiving a force from the spherical portion 92. The interval between the first grooves 721 is widened until the spherical portion 92 can move upward. The spherical portion 92 can move upward. The spherical portion 92 moves upward along the first groove portion 721 to the concave portion 72A. Here, as described above, the diameter L22 of the receiving portion 93 including the concave portion 72A is slightly larger than the diameter L32 of the spherical portion 92. Therefore, after the spherical portion 92 moves to the concave portion 72A, the first groove portion 721 no longer receives a force from the spherical portion 92, and the elastic deformation returns to its original state. The interval between the first grooves 721 returns to L21. The spherical portion 92 is held from both left and right sides by the concave portion 72A, and movement in the direction toward both the upper and lower sides is restricted.

  In the above process, the connecting portion 91 moves upward along the first groove portion 721. Here, as described above, the diameter L31 of the connecting portion 91 (see FIG. 7) is slightly smaller than the distance L21 between the first grooves 721. Therefore, the upward movement of the connecting portion 91 is not hindered by the first groove portion 721.

  Next, the cover 76 is arranged on the front side of the main body 71 of the fixing member 7. The cover 76 is moved toward the main body 71. The cover 76 covers the front opening of the main body 71. The protrusion 76D of the cover 76 and the recess 72A of the main body 71 (see FIGS. 10 and 11) are arranged along a common virtual sphere. The protruding portion 76D holds the spherical portion 92 held by the concave portion 72A from the front side. The projecting portion 76D and the concave portion 72A form a receiving portion 93. As described above, the diameter L22 of the receiving portion 93 is slightly larger than the diameter L32 of the spherical portion 92. For this reason, the spherical body portion 92 is slidably supported by the receiving portion 93.

  As shown in FIGS. 10 to 12, the protrusion 76 </ b> C of the cover 76 is inserted into the second groove 722 of the cutout groove 72 of the main body 71 from the front side. The diameter L22 of the protrusion 76C is slightly smaller than the diameter of the second groove 722. For this reason, the insertion of the protrusion 76C into the second groove 722 is not hindered. The protrusion 76C closes the second groove 722. Thus, the spherical body 92 is prevented from coming off the fixing member 7 via the second groove 722.

  As shown in FIG. 5, a screw 710 is inserted into each of the two holes 71A of the main body 71 from the rear side. As shown in FIGS. 10 and 12, the two screws 710 are screwed into two screw holes 76A (see FIG. 5) of the cover 76. The cover 76 is fixed to the main body 71 while covering an opening on the front side surface of the main body 71.

<Operation overview of wearing clip 3>
In the wearing clip 3, the protruding portion 821 (see FIGS. 10 to 12) provided on the distal end portion 820 of the hook portion 82 of the regulating portion 8 is a distal end portion of the engaging projection 53 of the first plate portion 51 of the clip member 5. 530 (see FIGS. 6 to 8) can be disengaged. FIGS. 14 to 16 show a state in which the engagement protrusion 53 is detached from the hook portion 82 (hereinafter, referred to as a “disengaged state”). In the detached state, the distal end portion 530 of the engagement protrusion 53 is disposed outside the space behind the curved portion 82A of the hook portion 82 and the front side of the flat portion 82B. Hereinafter, spaces inside and outside the space behind the curved portion 82A of the hook portion 82 and the front side of the flat portion 82B are referred to as “inside the hook portion 82” and “outside the hook portion 82”, respectively. In the detached state, the clip member 5 can swing and rotate with respect to the fixed member 7 in response to the spherical portion 92 of the connecting portion 9 sliding with respect to the receiving portion 93.

  Details are as follows. FIG. 14 shows a case where the connecting portion 91 (see FIGS. 6 and 7) of the connecting portion 9 extends rearward and obliquely upward from the spherical portion 92 (see FIGS. 6 and 7). FIG. 15 shows a case where the ball portion 92 slides with respect to the receiving portion 93 from the state of FIG. 14 and the clip member 5 swings upward by about 90 degrees about the left-right direction as an axis. The connecting portion 91 is in a state of extending upward from the spherical portion 92. On the other hand, FIG. 16 shows that the sphere portion 92 slides with respect to the receiving portion 93 from the state shown in FIG. The figure shows a case where the robot slightly swings downward about the left-right direction. The connecting portion 91 is in a state of extending rearward from the spherical portion 92. Although not shown, for example, it is also possible that the sphere portion 92 slides with respect to the receiving portion 93 from the state of FIG. 15 and the clip member 5 rotates about the vertical direction as an axis.

  In the state shown in FIG. 14, the distal end 530 of the engagement projection 53 of the clip member 5 comes into contact with the projection 821 of the hook 82 of the regulating section 8 from the rear side. Therefore, the movement of the distal end portion 530 of the engagement protrusion 53 from the outside to the inside of the hook portion 82 is suppressed by the protrusion portion 821 of the hook portion 82.

  On the other hand, in the state of FIG. 14, a case where a force in a direction of swinging downward about the left-right direction is applied to the clip member 5 is illustrated. Here, as described above, the extending portion 81 of the restricting portion 8 has flexibility. For this reason, when a force is applied to the clip member 5, the extending portion 81 is elastically deformed, and the curved portion 82A and the flat portion 82B of the hook portion 82 move downward. Thus, the distal end portion 530 of the engagement protrusion 53 can move from the outside to the inside of the hook portion 82. When the distal end portion 530 of the engagement protrusion 53 is disposed inside the hook portion 82, the engagement protrusion 53 is loosely fitted to the hook portion 82. Hereinafter, this state is referred to as a “free-fit state”. In the loose fit state, the movement of the engagement projection 53 is limited to a predetermined range by the hook portion 82. As a result, the swing and rotation of the clip member 5 are restricted within a predetermined range.

  The details of the loose fit state are as follows. As illustrated in FIG. 17, a case where the clip member 5 swings around the left-right direction in the loosely-fitted state and the distal end portion 530 of the engagement protrusion 53 moves rearward (solid line in the drawing) is illustrated. . In this case, the distal end portion 530 of the engagement protrusion 53 contacts the protrusion 821 of the hook portion 82 from the front side. The rearward movement of the engaging projection 53 at the distal end portion 530 is prevented, and the swing of the clip member 5 is restricted. On the other hand, the case where the clip member 5 swings around the left-right direction and the tip end portion 530 of the engagement protrusion 53 moves toward the front side (two-dot chain line in the figure) is illustrated. In this case, the distal end portion 530 of the engaging projection 53 comes into contact with the curved portion 82A of the hook portion 82 from the rear side. The forward movement of the distal end portion 530 of the engagement protrusion 53 is prevented, and the swing of the clip member 5 is restricted. As described above, in the loose fit state, the swing of the clip member 5 about the left-right direction is restricted within a predetermined range.

  In addition, as shown in FIG. 18, a case where the clip member 5 swings around the front-rear direction and the distal end portion 530 of the engagement protrusion 53 moves toward either the left or right side is illustrated. For example, when the distal end portion 530 of the engagement protrusion 53 moves rightward (solid line in the figure), the left end corner 53A of the distal end portion 530 (see FIG. 8) comes into contact with the curved portion 82A of the hook portion 82 from above. I do. The rightward movement of the engagement protrusion 53 is prevented, and the swing of the clip member 5 is restricted. On the other hand, when the distal end portion 530 of the engagement protrusion 53 moves to the left (two-dot chain line in the drawing), the right end corner 53A of the distal end portion 530 (see FIG. 8) Contact from. The movement of the engagement protrusion 53 to the left is prevented, and the swing of the clip member 5 is restricted. As described above, in the loose fit state, the swing of the clip member 5 about the axis in the front-rear direction is restricted to a predetermined range.

<How to use the wearing clip 3>
As shown in FIG. 4, the wearing clip 3 is fixed to the concave portion 23 of the second cover 20B of the printing device 2. The two screws 230 are inserted into the two holes 71B and 76B (see FIG. 5) of the fixing member 7 from the rear side, and screwed into the two screw holes 23A of the recess 23. Thereby, the fixing member 7 is fixed to the printing device 2. As shown in FIGS. 1 and 2, in a state where the fixing member 7 is fixed to the printing apparatus 2, a substantially half portion of the upper side of the fixing member 7 projects above the upper end of the printing apparatus 2. For this reason, the connection part 9 is in a state of extending from the upper side to the rear side from the upper end of the printing apparatus 2. The extending portion 81 of the regulating portion 8 extends downward along the rear surface of the second cover 20B of the printing device 2. The clip member 5 protrudes rearward with respect to the rear side surface of the second cover 20B of the printing device 2.

  A force is applied to the first plate portion 51 and the second plate portion 52 of the holding portion 50 of the clip member 5 in a direction to increase the interval. The space between the first plate portion 51 and the second plate portion 52 is widened by elastic deformation. A gap is generated between the tip end portion 540 of the protruding rib 54 (see FIG. 7) and the second plate portion 52. The belt worn by the user is inserted from below through the gap. The belt is disposed between the first plate portion 51 and the second plate portion 52. The space between the first plate portion 51 and the second plate portion 52 returns to the original space when there is no longer any force in the direction of widening the space. As a result, the distal end portion 540 of the protruding rib 54 (see FIG. 7) and the second plate portion 52 return to the original contact state. The holding portion 50 holds the belt between the first plate portion 51 and the second plate portion 52. The protruding rib 54 restricts the belt from falling down from between the first plate portion 51 and the second plate portion 52. Thereby, the printing device 2 is held on the belt.

  As shown in FIGS. 14 to 16, when the wearing clip 3 is in the detached state, the clip member 5 can swing and rotate with respect to the fixing member 7. Here, when the swing is regarded as a part of the rotation, it can be paraphrased that the clip member 5 is rotatable with respect to the fixed member 7. Further, since the state of the clip member 5 is fixed by the belt, the fixing member 7 and the printing apparatus 2 can be rotated with respect to the clip member 5. That is, the above description based on the fixing member 7 can be rephrased that the fixing member 7 is rotatable with respect to the clip member 5 when viewed with the clip member 5 as a reference.

  As shown in FIGS. 17 and 18, when the wearing clip 3 is in the loosely fitted state, the rotation of the clip member 5 with respect to the fixing member 7 is restricted within a predetermined range. This means that the rotation of the fixing member 7 with respect to the clip member 5 is restricted within a predetermined range when the clip member 5 is used as a reference.

<Main actions and effects of the present embodiment>
As described above, the wearing clip 3 can hold the printing device 2 fixed to the fixing member 7 on the belt while the holding portion 50 of the clip member 5 is held between the belts. The connecting portion 9 rotatably connects the fixing member 7 to the clip member 5. The restricting portion 8 provided on the fixing member 7 can be disengaged from the clip member 5. In the detached state in which the clip member 5 is detached from the restricting portion 8, the rotation of the fixing member 7 with respect to the clip member 5 is not restricted by the restricting portion 8 (see FIGS. 14 to 16). For this reason, the wearing clip 3 can freely change the direction of the printing device 2 with respect to the user. On the other hand, the rotation of the fixing member 7 with respect to the clip member 5 is regulated by the regulating portion 8 in a loosely fitted state in which the regulating portion 8 is loosely fitted to the clip member 5 (see FIGS. 17 and 18). For this reason, the wearing clip 3 can stabilize the orientation of the printing device 2 by making the orientation of the printing device 2 relative to the user unchangeable. Thus, the wearing clip 3 can switch between a state in which the orientation of the printing device 2 can be changed and a state in which the direction cannot be changed.

  The rotation of the clip member 5 is regulated by the engagement protrusion 53 provided at the lower end of the first plate portion 51 loosely fitting into the hook portion 82. Here, the connection portion 9 extends from a portion of the fixing member 7 above the upper end portion of the printing device 2. The spherical portion 92 of the connection portion 9 is slidably supported by a receiving portion 93 of the connection portion 9 at a portion above the upper end portion of the printing device 2. Therefore, the length between the spherical portion 92 and the hook portion 82 in the vertical direction is longer than the length between the upper end portion of the printing device 2 and the hook portion 82. In addition, the rotation of the clip member 5 can be appropriately regulated as the length of the hook portion 82 up to the spherical portion 92 increases. For this reason, in the wearing clip 3, the rotation of the clip member 5 can be more appropriately regulated by the hook portion 82 as compared with the case where the spherical portion 92 is supported below the upper end portion of the printing device 2.

  In a state where the rotation of the fixing member 7 with respect to the clip member 5 is restricted by the restricting portion 8, an appropriate direction of the fixing member 7 with respect to the clip member 5 may change according to the user's body type or posture. The reason is that the printing device 2 fixed to the fixing member 7 comes into contact with the user and tries to change the direction while the holding portion 50 of the clip member 5 is held between the belts. On the other hand, in the wearing clip 3, the engagement protrusion 53 and the hook portion 82 are loosely fitted. The rotation of the fixing member 7 with respect to the clip member 5 can be moved within a predetermined range. That is, the wearing clip 3 can have play in the direction of the fixing member 7 with respect to the clip member 5. Therefore, the wearing clip 3 allows the rotation of the fixing member 7 with respect to the clip member 5 to be movable within a predetermined range by the restricting portion 8 so that the orientation of the fixing member 7 with respect to the clip member 5 depends on the body type or posture of the user. Flexible.

  In the wearing clip 3, the length L23 of the hook portion 82 in the left-right direction is larger than the length L12 of the engagement protrusion 53 in the left-right direction. In this case, when the clip member 5 swings around the front-rear direction in the loosely fitted state (see FIG. 18), the tip 530 of the engaging projection 53 is placed on the curved portion 82 </ b> A of the hook 82. From the contact. For this reason, the hook portion 82 can appropriately regulate the movement of the engagement protrusion 53. Therefore, the wearing clip 3 can more reliably restrict the rotation of the fixing member 7 with respect to the clip member 5.

  When changing the wearing clip 3 from the detached state to the loosely-fitted state, the user moves the clip member 5 around the left-right direction until the engagement protrusion 53 is in the state of being disposed at the lowest position (see FIG. 17). Need to rotate. This is because the engaging projection 53 does not loosely fit into the projection 821 of the hook portion 82 unless this state is set. On the other hand, in the wearing clip 3, the distal end portion 820 of the hook portion 82 is curved in an arc shape. For this reason, for example, the user brings the engaging protrusion 53 into contact with the distal end portion 820 of the hook portion 82 and moves the distal end portion 530 of the engaging projection 53 along the distal end portion 820 of the hook portion 82 to approach each other. Thereby, the user can easily rotate the clip member 5 until the engagement protrusion 53 is disposed at the lowest position, that is, the engagement protrusion 53 can be loosely fitted to the protrusion 821 of the hook portion 82. Can be.

  The corners 53A at both ends of the distal end portion 530 of the engagement projection 53 are rounded. For this reason, it is possible to suppress the corner 53A from being caught in the process of moving the distal end portion 530 of the engagement protrusion 53 along the distal end portion 820 of the hook portion 82. Accordingly, the user can smoothly fit the engagement protrusion 53 into the hook portion 82, and can put the wearing clip 3 into the loosely fitted state.

  The first plate portion 51 of the clip member 5 has a projecting rib 54. The lower side surface 542 of the projecting rib 54 is inclined upward toward the rear side. In this case, the user brings the upper end of the belt into contact with the lower side surface 542 of the protruding rib 54 and moves the belt upward along the lower side surface 542 so that the distal end portion 540 of the protruding rib 54 and the second plate 52 The belt can be guided toward the gap between. Therefore, the user can easily guide the belt between the first plate portion 51 and the second plate portion 52 of the clip member 5. The corners 54A at both ends of the distal end portion 540 of the projecting rib 54 are chamfered. For this reason, the wearing clip 3 can suppress that the belt is caught at the corner 54A in the process of guiding the belt and hinders the movement of the belt. Therefore, the user can smoothly guide the belt to the wearing clip 3.

  In the normal state (the state in which the clip member 5 is not elastically deformed), the distal end portion 540 of the protruding rib 54 comes into contact with the second plate portion 52. The projecting rib 54 closes the gap between the first plate 51 and the second plate 52. For this reason, the detachment of the belt from the clip member 5 can be suppressed by the protruding ribs 54 in the state in which the belt is clamped by the clamping portion 50.

  In the wearing clip 3, the vertical length of the second plate portion 52 is longer than the vertical length of the first plate portion 51. The second plate portion 52 protrudes below the first plate portion 51. In this case, the user can position the belt by pressing the belt from the front side to a portion of the second plate portion 52 that protrudes below the first plate portion 51. Therefore, the user can smoothly guide the positioned belt between the first plate portion 51 and the second plate portion 52.

<Modification>
The present invention is not limited to the above embodiment, and various modifications are possible. The object that the clip member 5 of the wearing clip 3 holds by the holding portion 50 is not limited to the belt worn by the user. For example, the wearing clip 3 may be used by being attached to a waist portion, a pocket, or the like of pants.

  In the wearing clip 3, the receiving portion 93 of the connecting portion 9 is not limited to being provided on the fixing member 7 side, and may be provided on the clip member 5 side or provided on both the fixing member 7 and the clip member 5. You may be. In the above embodiment, the connecting portion 9 is a so-called ball joint having the connecting portion 91, the spherical portion 92, and the receiving portion 93. On the other hand, the connecting portion 9 may be another member capable of rotatably connecting the fixing member 7 to the clip member 5. For example, the connection portion 9 may be a rubber joint, a bellows-like flexible joint, a string, or the like. The first plate portion 51 may extend further below the engagement protrusion 53. That is, the engagement protrusion 53 may protrude forward from a portion above the lower end of the first plate portion 51. The hook portion 82 of the restricting portion 8 may not be provided on the extension portion 81, and may protrude rearward from the rear side surface of the second cover 20B of the printing device 2, for example. That is, the hook portion 82 may be provided in the printing device 2.

  When the wearing clip 3 is in the loosely fitted state, the clip member 5 can swing and rotate within a predetermined range with respect to the fixing member 7. On the other hand, the engagement protrusion 53 may be engaged with the hook portion 82 without play. That is, the clip member 5 may be engaged with the fixed member 7 so as not to swing and rotate.

  The length of the hook portion 82 in the left-right direction may be the same as the length of the engagement protrusion 53 in the left-right direction, or may be shorter than the length of the engagement protrusion 53 in the direction. The tip portion 820 of the hook portion 82 may extend linearly in the left-right direction, or may be curved in an arcuate shape depressed upward. The corners 820A at the left and right ends of the tip 820 of the hook portion 82 may be angular. The tip 820 of the hook 82 may have a flat shape without the protrusion 821.

  The distal end portion 540 of the protruding rib 54 may extend linearly in the left-right direction, or may be curved in an arcuate concave upward. The corners 54A at the left and right ends of the distal end 540 of the protruding rib 54 may be angular. The lower side surface 542 of the protruding rib 54 may not be inclined, and may be perpendicular to the up-down direction. The protruding rib 54 may be switchable between a state in which it protrudes from the first plate portion 51 and a state in which it does not protrude. For example, the protruding rib 54 may be swingable around a front end. The protruding rib 54 may be provided on the second plate portion 52. The vertical length of the second plate portion 52 may be substantially the same as the vertical length of the first plate portion 51, or may be shorter than the first plate portion 51.

  The wearing clip 3 may be integrated with the printing device 2. That is, the clip member 5, the fixing member 7, the restricting portion 8, and the connecting portion 9 of the wearing clip 3 may be formed as a part of the second cover 20 </ b> B of the printing device 2.
