Description

  The technology disclosed in the present specification relates to an information code reader capable of reading an information code.

  Patent Document 1 discloses an information code reading device developed by the present applicant. The information code reader includes a case, a cable, and a fixing member. A through hole is formed at the end of the case, and a notch is formed in a part of the through hole in the circumferential direction. A flange portion that protrudes in the radial direction of the cable and that can pass through the through hole of the case is formed at the end portion of the cable. When the flange portion of the cable is inserted into the case through the through hole of the case, the end portion of the cable is connected to the control mechanism accommodated in the case. The fixing member has a cylindrical main body in which an insertion hole through which the cable is inserted is formed, and a convex portion protruding in the radial direction of the main body from the outer peripheral surface of the main body. A convex portion protruding in the radial direction of the main body from the outer peripheral surface of the main body is formed on a part of the fixing member in the circumferential direction of the main body. The insertion hole of the fixing member cannot pass the flange portion of the cable. In the first state in which the circumferential position of the notch coincides with the circumferential position of the protrusion, the main body of the fixing member can pass through the through hole of the case by the protrusion passing through the notch. In the second state where the circumferential position of the notch and the circumferential position of the protrusion do not coincide, the protrusion prevents the body of the fixing member from passing through the through hole of the case. In this information code reader, the end portion of the cable and the main body of the fixing member are inserted into the through hole of the case as a first state in which the circumferential position of the notch and the circumferential position of the convex portion coincide. Next, the fixing member is rotated around its axis with respect to the case, so that the circumferential position of the notch and the circumferential position of the convex portion do not coincide with each other. Accordingly, the convex portion of the fixing member is seated on the peripheral portion of the hole on the inner surface of the case, the fixing member cannot pass through the through hole of the case, and the fixing member is held in the case. Since the flange portion of the cable cannot pass through the insertion hole of the main body of the fixing member, the cable is also held in the case by holding the fixing member in the case.

JP 2013-20435 A

  In the information code reader of Patent Document 1, after inserting a fixing member into the through hole of the case, the fixing member is rotated with respect to the case, thereby holding the cable and the fixing member in the case. Usually, since frictional force acts on the contact surface between the case and the fixing member, the fixing member does not freely rotate with respect to the case, and the fixing member and / or the cable are prevented from being detached from the case to some extent. The However, when the information code is read by the information code reading device, the user holds the case and moves the information code reading device to the reading position with respect to the information code. For this reason, a force is applied to the fixing member, and the fixing member may unintentionally rotate with respect to the case. As a result, there is a possibility that the convex portion rotates to a position passing through the notch, the main body passes through the through hole, and the fixing member is detached from the case. If the fixing member is removed from the case, there is a possibility that the cable may come off.

  In this specification, the technique which can suppress appropriately that a cable remove | deviates from a case is provided.

  The technology disclosed in this specification is an information code reader capable of reading an information code. The information code reader includes a case in which a through hole is formed, a cable having an end portion that is detachably inserted into the through hole of the case, and a cylindrical main body in which an insertion hole through which the cable is inserted is formed. A fixing member. A notch is formed in a part of the circumferential direction of the through hole of the case. A fitting recess is formed in the inner surface of the case and in the peripheral portion of the through hole. At the end of the cable, a flange that protrudes in the radial direction and that can pass through the through hole of the case is formed. A convex portion protruding in the radial direction of the main body from the outer peripheral surface of the main body is formed on a part of the fixing member in the circumferential direction of the main body. The insertion hole of the fixing member cannot pass the flange portion of the cable. In the first state in which the circumferential position of the notch coincides with the circumferential position of the protrusion, the main body of the fixing member can pass through the through hole of the case by the protrusion passing through the notch. In the second state where the circumferential position of the notch and the circumferential position of the protrusion do not coincide, the protrusion prevents the body of the fixing member from passing through the through hole of the case. When the main body of the fixing member passes through the through hole of the case, it can be switched from the first state to the second state. In the second state, the convex portion fits into the fitting concave portion on the inner surface of the case and is in the second state. To be in the first state.

  In the above information code reader, a fitting recess is formed on the inner surface of the case and on the peripheral portion of the through hole. The convex portion of the fixing member that has passed through the notch portion of the through hole is fitted to the fitting concave portion in the case when the fixing member rotates with respect to the case, and the fixing member is assembled to the case. Since the flange portion of the cable cannot pass through the insertion hole of the fixing member, the cable is prevented from coming out of the case when the fixing member is assembled to the case. In the state where the fixing member is assembled to the case, since the convex portion of the fixing member is fitted in the fitting concave portion in the case, a force is applied to the fixing member as the information code reader is used. Moreover, it is suppressed that a fixing member rotates with respect to a case. That is, the transition from the second state to the first state is restricted. Therefore, it is possible to suppress the fixing member from being removed from the case, and appropriately suppress the cable from being removed from the case.

The stopper 30a is formed at the end of the fitting recess 28 on the side far from the notch 25a. Moreover, as shown in FIG. 6, the notch part 25a is formed in the taper shape from which the opening width becomes narrow toward the inner side from the outer side of the 2nd case body 20b. Although not shown, the notch 25b is also formed in the same shape as the notch 25a. Therefore, when the convex portions 66a and 66b of the fixing member 60 are passed through the notches 25a and 25b, the convex portions 66a and 66b are easily introduced into the notches 25a and 25b. In the present embodiment, as shown in FIG. 5, the tapered portion and the fitting recess are not formed on the inner surface of the first case body 20a.

  As shown in FIGS. 2 and 4, a plurality of engagement claws 32 that can be inserted into the engagement holes 46 of the protection member 40 are formed at the lower end portion of the case 20. Each engagement claw 32 is formed so as to protrude downward from the lower end of the case 20.

(Protective member 40)
The protection member 40 is made of, for example, a softer and higher elastic material than the case 20 (for example, a flexible material such as rubber or elastomer). As shown in FIGS. 2 and 4, the protection member 40 is formed with a passage hole 42 penetrating the protection member 40 in the vertical direction. Two notches 44 a and 44 b are formed in the circumferential direction of the passage hole 42. A plurality of engaging holes 46 into which the engaging claws 32 of the case 20 can be inserted are formed in the peripheral portion of the passage hole 42 and on the upper surface of the protection member 40. The protection member 40 can be attached to the lower end portion of the case 20 by inserting the plurality of engagement claws 32 of the case 20 into the plurality of engagement holes 46 of the protection member 40.

  When the protective member 40 is attached to the lower end portion of the case 20, the through hole 42 of the protective member 40 and the through hole 24 of the case 20 form a single through hole. Further, the circumferential positions of the notches 44 a and 44 b of the passage hole 42 of the protection member 40 coincide with the circumferential positions of the notches 25 a and 25 b of the through hole 24 of the case 20, respectively.

(Cable 80)
As shown in FIG. 2, the cable 80 includes a connector 82 and a wiring 90 extending from the connector 82. As shown in FIG. 3, the distal end portion 82 a of the connector 82 is inserted into the passage hole 42 of the protection member 40 and the through hole 24 of the case 20 and connected to the socket 102 in the case 20. At that time, the rear end portion 82 b of the connector 82 is disposed outside the case 20. The outer shell of the connector 82 is formed of a hard resin material. A plurality of slits (not shown) are formed on the outer peripheral surface of the rear end portion 82b. As a result, the rear end portion 82b has flexibility. The wiring 90 extends from the rear end portion 82 b of the connector 82.

  A flange portion 84 that protrudes in the radial direction is formed at the distal end portion 82 a of the connector 82. The flange portion 84 is formed in such a size that it can pass through the passage hole 42 of the protection member 40 and the through hole 24 of the case 20. Two convex portions 86 a and 86 b that protrude in the radial direction from the outer peripheral surface of the flange portion 84 are formed on a part of the flange portion 84 in the circumferential direction. In addition, a ring portion 88 having a protruding amount smaller than that of the flange portion 84 is formed on the lower side of the distal end portion 82 a of the connector 82 that is spaced a predetermined distance from the flange portion 84.

  When the protective member 40 is attached to the lower end of the case 20, the circumferential positions of the two notches 44 a and 44 b of the passage hole 42 of the protective member 40 (that is, the two through holes 24 of the case 20). In the state in which the circumferential positions of the notches 25a and 25b and the circumferential positions of the protrusions 86a and 86b coincide with each other, the protrusions 86a and 86b replace the notches 44a and 44b and the notches 25a and 25b. It can pass. In this case, the protrusions 86a and 86b pass through the notches 44a and 44b and the notches 25a and 25b, so that the tip portion 82a of the connector 82 passes through the through hole 42 of the protection member 40 and the through hole 24 of the case 20. To do. The distal end portion 82 a of the connector 82 that has passed through the through hole 24 of the case 20 is inserted into the socket 102 and can be connected to the substrate 100 in the case 20.

(Fixing member 60)
The fixing member 60 is made of a resin material that is harder than the protection member 40. As shown in FIG. 2, the fixing member 60 has a cylindrical main body 62. The main body 62 is formed with an insertion hole 64 through which the cable 80 is inserted. However, the insertion hole 64 is formed in a diameter through which the flange portion 84 of the cable 80 cannot pass. Two convex portions 66 a and 66 b projecting in the radial direction of the main body 62 from the outer peripheral surface of the main body 62 are formed in a part of the upper end portion of the main body 62 in the circumferential direction. A protrusion 68 that protrudes from the outer peripheral surface of the main body 62 in the radial direction of the main body 62 is formed on the lower side of the main body 62 at a predetermined distance from the positions of the protrusions 66a and 66b.

  When the protective member 40 is attached to the lower end of the case 20, the circumferential positions of the two notches 44 a and 44 b of the passage hole 42 of the protective member 40 (that is, the two through holes 24 of the case 20). In the circumferential direction of the notches 25a and 25b) and the circumferential position of the projections 66a and 66b (that is, the first state in FIG. 5), the projections 66a and 66b are notched. It can pass through the portions 44a and 44b and the notches 25a and 25b. In this case, the convex portions 66a and 66b pass through the cutout portions 44a and 44b and the cutout portions 25a and 25b, so that the main body 62 of the fixing member 60 passes through the through hole 42 of the protective member 40 and the through hole 24 of the case 20. To do.

  Further, by rotating the main body 62 in the circumferential direction (counterclockwise in FIG. 5) in a state where the main body 62 of the fixing member 60 has passed through the through hole 24 of the case 20, the positions and convexities of the notches 25a and 25b are detected. Transition is made to a state where the parts 66a and 66b do not match (that is, the second state in FIG. 5). In the second state, the main body 62 of the fixing member 60 cannot pass through the through hole 24 of the case 20. When the main body 62 is rotated, as shown in FIG. 7, the convex portion 66 a is guided in the direction of the fitting concave portion 28 along the tapered portion 26 and then fitted into the fitting concave portion 28. Returning from the second state to the first state is restricted by fitting the convex portion 66 a into the fitting concave portion 28. As described above, since the flange portion 84 of the cable 80 cannot pass through the insertion hole 64 of the fixing member 60, the cable 80 is prevented from being detached from the case 20 by assembling the fixing member 60 to the case 20. At the same time, as shown in FIG. 3, the ring portion 88 of the cable 80 is fixed so as to be pressed upward by the step portion formed on the inner periphery of the fixing member 60. This also prevents the cable 80 from coming out of the case 20.

  When the main body 62 is rotated in the circumferential direction (counterclockwise in FIG. 5) in a state where the main body 62 of the fixing member 60 has passed through the through hole 24 of the case 20, movement of the convex portions 66a and 66b in the circumferential direction is performed. Is regulated by the stoppers 30a and 30b. That is, even if the main body 62 is excessively rotated, the rotation of the fixing member 60 relative to the case 20 is restricted by the protrusions 66a and 66b coming into contact with the stoppers 30a and 30b.

  As shown in FIG. 3, the protruding portion 68 of the fixing member 60 comes into contact with the peripheral portion of the passage hole 42 when the main body 62 passes through the passage hole 42 of the protection member 40. Further, when the protrusion 66 a of the fixing member is fitted in the fitting recess 28, the protruding portion 68 fixes the protective member 40 to the case 20 by sandwiching the protective member 40 between the protruding portion 68 and the case 20.

(Assembly of information code reader 10)
Next, a procedure for completing the information code reader 10 of FIG. 1 by combining the case 20, the protective member 40, the cable 80, and the fixing member 60 will be described.

  First, the protection member 40 is attached to the lower end portion of the case 20 by inserting the plurality of engagement claws 32 of the case 20 into the plurality of engagement holes 46 of the protection member 40 (see FIGS. 2 and 3). . When the protection member 40 is attached to the lower end portion of the case 20, the passage hole 42 of the protection member 40 and the through hole 24 of the case 20 become one through hole. Further, the circumferential positions of the cutout portions 44a and 44b of the passage hole 42 of the protection member 40 coincide with the circumferential positions of the cutout portions 25a and 25b of the through hole 24 of the case, respectively.

  Next, the circumferential positions of the two notches 44a and 44b of the passage hole 42 of the protection member 40 (that is, the circumferential positions of the two notches 25a and 25b of the through hole 24 of the case 20) and the cable The convex portions 86a, 86b of the 80 are aligned with the circumferential positions of the cable 80, and the distal end portion 82a of the connector 82 of the cable 80 is passed through the passage hole 42 of the protective member 40 and the through hole 24 of the case 20, and the case 20 Insert inside. The tip portion 82a inserted into the case 20 is inserted into the socket 102 and connected to the substrate 100 (see FIG. 3).

  Next, the circumferential positions of the two notches 44a and 44b of the passage hole 42 of the protection member 40 (that is, the circumferential positions of the two notches 25a and 25b of the through hole 24 of the case 20) and the convex The positions of the portions 66a and 66b are aligned with each other (that is, the first state in FIG. 5 is formed), and the main body 62 of the fixing member 60 is connected to the passage hole 42 of the protection member 40 and the through hole of the case 20. 24 is inserted and inserted into the case 20.

  With the main body 62 of the fixing member 60 passing through the through hole 24 of the case 20, the main body 62 is rotated in the circumferential direction (counterclockwise in FIG. 5). By turning the main body 62 in the circumferential direction, the position of the notches 25a and 25b and the convex portions 66a and 66b are shifted to a state (that is, the second state in FIG. 5). As shown in FIG. 7, the convex portion 66 a is guided in the direction of the fitting concave portion 28 along the tapered portion 26, and then fits into the fitting concave portion 28. At this time, even if the main body 62 is excessively rotated, the convex portions 66a and 66b abut against the stoppers 30a and 30b, so that excessive rotation of the fixing member 60 is restricted. When the convex portion 66a is fitted into the fitting concave portion 28, the second state is maintained and the return from the second state to the first state is restricted. That is, when the convex portion 66 a of the fixing member 60 is rotated along the tapered portion 26 toward the fitting concave portion 28, the fixing member 60 is pushed into the case 20 by the user. At this time, since the protruding portion 68 of the fixing member 60 presses the protective member 40 upward, the protective member 40 is elastically deformed. Since the protective member 40 is elastically deformed, the user can easily push the fixing member 60 into the case 20. When the convex portion 66a of the fixing member 60 is fitted into the fitting concave portion 28, the pushing operation of the fixing member 60 into the case 20 by the user is stopped. As a result, the fixing member 60 is biased downward by the elastic force of the protection member 40, and the protrusion 66 a of the fixing member 60 is restricted from coming off the fitting recess 28.

  Since the flange portion 84 of the cable 80 cannot pass through the insertion hole 64 of the fixing member 60, the cable 80 is prevented from being detached from the case 20 by assembling the fixing member 60 to the case 20. Further, as shown in FIG. 3, the ring portion 88 of the cable 80 is fixed so as to be pressed upward by a step portion formed on the inner periphery of the fixing member 60. This also prevents the cable 80 from coming out of the case 20.

  When removing the fixing member 60 from the case 20, the following operation is performed. First, the fixing member 60 is pushed into the inside of the case 20 to release the fitting between the convex portion 66a and the fitting concave portion 28 (see FIG. 7). That is, the convex portion 66 a of the fixing member 60 is detached from the fitting concave portion 28 due to the elastic deformation of the protective member 40. The main body 62 is rotated in the circumferential direction (clockwise in FIG. 5) while maintaining the state where the convex portion 66a is detached from the fitting concave portion. By turning the main body 62 in the circumferential direction, the state shifts to the first state in which the positions of the notches 25a and 25b coincide with the convex portions 66a and 66b. In the first state, since the main body 62 of the fixing member 60 can pass through the through hole 24 of the case 20 and the passage hole 42 of the protection member 40, the fixing member 60 can be removed from the case 20 and the protection member 40. . After the fixing member 60 is removed from the case 20 and the protection member 40, the cable 80 and the protection member 40 can be removed from the case 20.

  The configuration of the information code reading device 10 according to the present embodiment has been described above. As described above, since the flange portion 84 of the cable 80 cannot pass through the insertion hole 64 of the fixing member 60 (see FIG. 3), the cable 80 comes out of the case 20 when the fixing member 60 is assembled to the case 20. It is prevented. In a state in which the fixing member 60 is assembled to the case 20, the convex portion 66 a of the fixing member 60 is fitted in the fitting concave portion 28 in the case 20, so that the fixing member 60 is used with the use of the information code reading device 10. Even when a force is applied to the fixing member 60, the fixing member 60 is prevented from rotating with respect to the case 20. In other words, the transition from the second state in FIG. 5 to the first state is restricted. Therefore, it is possible to suppress the fixing member 60 from being detached from the case 20 and appropriately prevent the cable 80 from being detached from the case 20.

  As shown in FIGS. 5 and 7, a tapered portion 26 is formed on the inner surface of the second case body 20 b and on the peripheral portion of the through hole 24. The tapered portion 26 is formed between the cutout portion 25a and the fitting recess 28. Therefore, the convex portion 66 a that has entered the case 20 through the notch 25 a is guided in the direction of the fitting concave portion 28 along the taper portion 26 as the fixing member 60 rotates with respect to the case 20. Then, it is fitted into the fitting recess 28. Therefore, it becomes easy for a user who performs the operation of assembling the fixing member 60 to the case 20 to recognize that the convex portion 66 a is fitted in the fitting concave portion 28 in the case 20. Therefore, the convex part 66a and the fitting recessed part 28 can be fitted appropriately.

  Further, as shown in FIG. 5, stoppers 30 a and 30 b are formed in the case 20 to limit the movement of the convex portions 66 a and 66 b of the fixing member 60 in the circumferential direction. Therefore, the protrusions 66a and 66b abut against the stoppers 30a and 30b, so that excessive rotation of the fixing member is restricted, and the protrusion 66a of the fixing member 60 is appropriately fitted into the fitting recess 28. Can do.

  In addition, the information code reader 10 of the present embodiment includes a protective member 40 formed of a material that is more flexible and elastic than the case 20 at the lower end of the case 20. Therefore, when the case 20 is dropped from the side where the cable 80 is attached, the impact at the time of dropping can be absorbed by the protective member 40, and propagation of the shock to the case 20 can be mitigated.

  As shown in FIG. 3, the protrusion 68 of the fixing member 60 is brought into contact with the peripheral portion of the passage hole 42 when the main body 62 passes through the passage hole 42 of the protection member 40. Further, the protrusion 68 fixes the protection member 40 to the case 20 by sandwiching the protection member 40 between the protrusion 20 and the case 20 when the protrusion 66 a of the fixing member is fitted in the fitting recess 28. Therefore, the protection member 40 can be firmly fixed to the case 20. Furthermore, the fixing member 60 is urged downward by the elastic force of the protection member 40, so that it is possible to effectively restrict the protrusion 66 a of the fixing member 60 from coming off from the fitting recess 28. Further, when the protective member 40 that is more flexible than the case 20 is deformed as necessary, when the convex portion 66a of the fixing member 60 is fitted into the fitting concave portion 28, and when the fitting is released. Operation can be performed easily.

  As mentioned above, although the Example of this invention was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, the following modifications may be included.

(Modification 1) In the above embodiment, as shown in FIG. 5, the tapered portion 26 and the fitting recess 28 are formed only on the second case body 20b side, and the tapered portion and the fitting are formed on the first case body 20a side. No joint recess is formed. However, the present invention is not limited thereto, and a tapered portion and a fitting recess may be formed on both the second case body 20b side and the first case body 20a side.

(Modification 2) The tapered portion 26 may be omitted. In that case, it is preferable that the protrusion amount of the fitting recess into the case is smaller than the protrusion amount of the other part of the inner surface of the case 20.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
