  By the way, when the structure for extending the cable from the case as described above is used, the user can easily access the cable end portion (that is, the portion where the cable is connected to the connector in the case) during maintenance or assembly. Therefore, it is desirable that the case can be opened and closed near the end of the cable. However, in the configuration of Patent Document 1, the portion for fixing the cable (3) to the case (1) is covered with the cable bush (13), and the fixing position of the cable (3) is deep inside the case. Since no structure for opening and closing the bush (13) is disclosed, it cannot be said that the cable end portion can be easily accessed.

  On the other hand, as a structure that can open and close the case near the end of the cable, the end of the case is formed in an opening shape, and a lid-like bottom piece is attached to the opening portion so as to be openable and closable with screws, A structure is conceivable in which a cable is inserted and fixed through the bottom piece. However, in this structure, when the bottom piece is assembled, it is necessary to tighten the screw, and when removing the bottom piece, it is necessary to remove the screw. Therefore, it takes time to assemble and remove the bottom piece. There is a problem that it ends up. Moreover, since a screw, a nut, etc. are needed as a member different from a case and a bottom piece, there also exists a problem of causing the increase in a number of parts.

  To solve this problem, it is conceivable to eliminate screws and nuts, but in order to eliminate screws, the cable should be firmly fixed to the case and the end of the case (cable extended). The problem is how to realize a configuration that can strengthen the output side. For example, when the user grasps the case and performs an information code reading operation, it is assumed that the case is moved in various directions, and a load that pulls the cable is applied on the case side. It is desirable that the cable is firmly fixed to the case so that a force is not easily applied to the electrical connection portion (connector or the like) at the end of the cable even when a tensile load is generated. In addition, it is assumed that the case may be accidentally dropped during use, and at that time, the cable may fall from the extending side. Durability against such impact is required.

  The present invention has been made in order to solve the above-described problems. In an optical information reading apparatus having a structure in which a cable is extended from a case and an end of the cable is assembled to the case, the case is provided near the end of the cable. It is an object of the present invention to provide a configuration that can realize a configuration that can be easily opened and closed with a reduced number of parts and that can further strengthen a portion where the case and the cable are assembled and the vicinity thereof.

In the inventions according to claims 1 to 10, since the fixing member is fixed to the grip portion having high rigidity, the fixing member can be stably attached to the case. And since the assembly of the cable to the gripping part and the assembly of the end piece to the gripping part are held by the fixing member stably fixed in this way, the cable can be firmly fixed to the case. In addition, the end piece can be stably held in the grip portion. Also, an end piece configured as a separate member from the gripping part is arranged on the tip side of the gripping part, and when the case falls from the cable extension side, the end piece receives an impact at the time of dropping. Therefore, the propagation of impact to the gripping portion can be mitigated by the end piece.
In addition, since the end piece is fixed to the distal end side of the gripping portion by the engagement between the engaged portion and the engaging portion, screw-less operation is achieved for fixing the end piece, and one end side of the tubular portion is provided. Since the fixing member is fixed to the gripping portion by engaging the provided engagement piece with the distal end side of the gripping portion, the fixing member is fixed with no screws. Therefore, a configuration that can easily open and close the case near the end of the cable can be realized with a reduced number of parts.

In the first aspect of the present invention, the engaging portion is constituted by an engaging claw extending from the distal end side of the gripping portion, and the engaged portion is constituted by an engaging hole into which the engaging claw is inserted. Yes. And when an engagement claw is inserted in an engagement hole, it is comprised so that the projection part formed in the engagement claw may be locked to the peripheral part of an engagement hole, The locking state is released by tilting toward the through-hole side, and the fixing member regulates the engagement claw so that it does not tilt toward the through-hole side when assembled to the grip portion. ing.
In this configuration, since the engaging claw is inserted into the engaging hole and the protrusion is locked to the peripheral edge of the engaging hole, the end piece is more stably engaged with the gripping portion. Can be combined. Further, when the fixing member is fixed, the engagement claw is restricted so as not to tilt toward the through hole side, and the locking state between the protrusion and the peripheral edge of the engagement hole is maintained so as not to be released. As long as the fixing member is not removed, the engaging claw and the engaging hole continue to be more reliably engaged, and the end piece is stably held by the gripping portion.

In the invention of Claims 2 and 3, the case is provided with a first case body that forms a part of the gripping part and a second case body that is assembled to the first case body and forms the other part of the gripping part. The hole portion is constituted by the portion constituting the distal end side of the grip portion in the first case body and the portion constituting the distal end side of the grip portion in the second case body.
Further, a first pin formed to extend from one end side of the first case body and a second pin formed to extend from one end side of the second case body are provided around the hole portion. A first insertion hole into which the first pin is inserted and a second insertion hole into which the second pin is inserted are formed around the through hole in the end piece.
The first case is inserted into the first insertion hole and the second pin is inserted into the second insertion hole, so that the first case body and the second case body are held in a coupled state on the distal end side of the grip portion. It has come to be.
In this configuration, since the divided case structure is adopted, it is easier to house and assemble the electronic component in the case. In addition, the first case body side first pin is inserted into the first insertion hole, and the second case body side second pin is inserted into the second insertion hole, so that the first case body and the first case body are formed on the distal end side of the grip portion. Since the two case bodies are held in a coupled state, the end portions (hole side) of both cases can be firmly coupled using the end pieces.

In the invention of claim 4, the end piece is made of a material that is more flexible than the case.
In this way, if the end piece arranged on the front end side of the gripping part is made of a material that is more flexible than the case, when the case falls from the cable extension side, the end piece is more resistant to impact when dropped. It can absorb, and the propagation of the impact to the holding part side can be further reduced.

In the fifth and sixth aspects of the invention, the fixing member is fixed to the gripping portion so as to sandwich the outer wall portion and the end piece on the distal end side of the gripping portion in the hole direction of the through hole.
According to this configuration, the end piece can be more firmly attached to the grip portion, and the connection in the through-hole direction (axial direction) can be stabilized.

In the invention of Claims 7 and 8 , a flange portion projecting in the axial radial direction of the cable and a first projection and a second projection projecting outward from the outer peripheral portion of the flange portion are formed on the end portion side of the cable. The flange portion, the first protrusion, and the second protrusion can be taken in and out of the grip portion through the hole portion,
The hole portion is formed with a first notch portion through which the first protrusion passes and a second notch portion through which the second protrusion passes when the flange portion is inserted into and removed from the hole portion,
The first protrusion has a larger circumferential width than the second protrusion, and the circumferential width of the second notch is smaller than the circumferential width of the first protrusion.
In this case, it is necessary to insert the cable into the hole in such a direction that the first protrusion passes through the first notch and the second protrusion passes through the second notch, and the first protrusion is inserted into the second notch. Since the cable cannot be inserted in the direction to pass through the part, the cable is easily inserted in a desired direction, and when it is attempted to be inserted in the wrong direction, it can be grasped before the flange part is inserted.

In the inventions according to claims 9 and 10 , a flange portion projecting in the axial radial direction of the cable and a first projection and a second projection projecting outward from the outer peripheral portion of the flange portion are formed on the end portion side of the cable. The flange portion, the first protrusion, and the second protrusion can be inserted into and removed from the gripping portion through the through hole. The through hole has a first portion when the flange portion is inserted into and removed from the through hole. One notch through which the protrusion passes and another notch through which the second protrusion passes are formed. The first protrusion has a larger width in the circumferential direction than the second protrusion, and the circumferential widths of the other notches are smaller than the circumferential width of the first protrusion.
In this case, it is necessary to insert the cable into the through hole so that the first protrusion passes through one notch and the second protrusion passes through the other notch. Because the cable cannot be inserted in the direction to pass through the notch of the cable, the cable can be easily inserted in the desired direction, and can be grasped before the flange portion is inserted if the cable is inserted in the wrong direction. .

(Main effects of the first embodiment)
In the optical information reading apparatus 1 according to the present embodiment, the fixing member 70 is fixed to the highly rigid gripping portion 3b, so that the fixing member 70 can be stably attached to the case 2. And since the assembly of the cable 90 to the grip part 3b and the assembly of the end piece 50 to the grip part 3b are held by the fixing member 70 that is stably fixed in this way, the cable 90 is attached to the case 2. It can be firmly fixed, and the end piece 50 can be stably held by the grip portion 3b. Further, an end piece 50 configured as a separate member from the gripping portion 3b is disposed on the distal end side of the gripping portion 3b, and when the case 2 is dropped from the cable 90 extending side, the end piece 50 is dropped. Since it is possible to receive the impact of time, the propagation of the impact toward the grip portion 3b can be reduced by the end piece 50.

  Further, since the end piece 50 is fixed to the distal end side of the grip portion 3b by the engagement between the engagement holes 56a and 56b and the engagement claws 10a and 10b, a screw-less operation is achieved for fixing the end piece 50. Since the fixing member 70 is fixed to the grip portion 3b by engaging the engagement pieces 76a and 76b provided on one end side of the cylindrical portion 75 with the tip side of the grip portion 3b, the fixing member 70 is fixed. The screw-less design is also planned. Therefore, a configuration that can easily open and close the case 2 near the end of the cable 90 can be realized with a reduced number of parts.

  In the present embodiment, the engaging portions are constituted by the engaging claws 10a and 10b extending from the distal end side of the grip portion 3b, and the engaged holes 56a and 56b into which the engaging claws 10a and 10b are inserted are engaged. A joint is formed. When the engaging claws 10a and 10b are inserted into the engaging holes 56a and 56b, the protrusions 10c and 10d formed on the engaging claws 10a and 10b are engaged with the peripheral edges of the engaging holes 56a and 56b, respectively. The engaging claw 10a, 10b tilts toward the through hole 55 from the locked state, and the locked state is released. And the fixing member 70 is controlled so that the engaging claws 10a and 10b do not tilt to the through-hole 55 side when assembled to the grip portion 3b.

  In this configuration, the engagement claws 10a and 10b are inserted into the engagement holes 56a and 56b, and the protrusions 10c and 10d are engaged with the peripheral portions of the engagement holes 56a and 56b. The end piece 50 can be more stably engaged with the grip portion 3b. Further, when the fixing member 70 is fixed, the engaging claws 10a and 10b are regulated so as not to tilt toward the through hole 55, and the projections 10c and 10d are locked to the peripheral portions of the engaging holes 56a and 56b. Since the state is maintained so as not to be released, unless the fixing member 70 is removed, the engaging claws 10a and 10b and the engaging holes 56a and 56b continue to engage with each other more reliably, and the end piece 50 becomes the grip portion 3b. Will be held stably.

Further, the case 2 used in the present embodiment has a configuration in which a first case body 2a that forms part of the grip portion 3b and a second case body 2b that forms the other portion of the grip portion 3b are assembled to each other. In addition, the hole 4 is configured by a portion constituting the distal end side of the grip portion 3b in the first case body 2a and a portion constituting the distal end side of the grip portion 3b in the second case body 2b.
Further, around the hole portion 4, the first pins 11 a and 11 b formed so as to extend from one end side of the first case 2 and the one end side of the second case body 2 are formed. The second pins 12a and 12b are provided. Around the through hole 55 in the end piece 50, the first insertion holes 51a and 51b and the second pins 12a and 12b into which the first pins 11a and 11b are inserted are provided. Second insertion holes 52a and 52b to be inserted are formed.
Then, the first pins 11a and 11b are inserted into the first insertion holes 51a and 51b, and the second pins 12a and 12b are inserted into the second insertion holes 52a and 52b. The case body 2a and the second case body 2 are held in a coupled state.

  In this configuration, since a divided case structure is employed, it is easier to house and assemble the electronic components in the case 2. The first pins 11a and 11b on the first case body side are inserted into the first insertion holes 51a and 51b, and the second pins 12a and 12b on the second case body 2 side are inserted into the second insertion holes 52a and 52b. As a result, the first case body 2a and the second case body 2 are held in a coupled state on the distal end side of the grip portion 3b. (Hole 4 side) can be firmly bonded.

In the present embodiment, the end piece 50 is made of a material that is more flexible than the case 2.
Thus, if the end piece 50 arranged on the front end side of the grip portion 3b is made of a material more flexible than the case 2, when the case 2 falls from the cable 90 extending side, the end piece 50 The impact at the time of dropping can be absorbed more, and the propagation of the impact toward the grip portion 3b can be further alleviated.

Further, the fixing member 70 is fixed to the grip portion 3 b so as to sandwich the outer wall portion on the tip end side of the grip portion 3 b and the end piece 50 in the hole direction of the through hole 55.
According to this configuration, the end piece 50 can be more firmly attached to the grip portion 3b, and the connection of the through hole 55 in the hole direction (axial direction) can be stabilized.

Further, on the end portion side of the cable 90, a flange portion 93 projecting in the axial radial direction of the cable 90, and a first projection 91 and a second projection 92 projecting outward from the outer peripheral portion of the flange portion 93 are formed. The flange portion 93, the first protrusion 91, and the second protrusion 92 can be taken in and out of the grip portion 3b through the hole portion 4,
The hole 4 is formed with a first notch 4a through which the first protrusion 91 passes and a second notch 4b through which the second protrusion 92 passes when the flange 93 is inserted into and removed from the hole 4. And
The first protrusion 91 has a larger circumferential width than the second protrusion 92, and the circumferential width of the second notch 4 b is smaller than the circumferential width of the first protrusion 91.

  In this case, it is necessary to insert the cable 90 into the hole 4 in such a direction that the first protrusion 91 passes through the first notch 4a and the second protrusion 92 passes through the second notch 4b. Since the cable 90 cannot be inserted in the direction in which the one protrusion 91 is intended to pass through the second notch 4b, the cable 90 is easily inserted in a desired direction. Can be grasped before insertion.

The through hole 55 has a notch 57a (one notch) through which the first protrusion 91 passes and a notch 57b through which the second protrusion 92 passes when the flange 93 is inserted into and removed from the through hole 55. (Other notches) are formed. The first protrusion 91 has a larger circumferential width than the second protrusion 92, and the circumferential width of the notch 57 b (other notch) is larger than the circumferential width of the first protrusion 91. Is also getting smaller.
In this way, the first protrusion 91 passes through the cutout portion 57a (one cutout portion), and the second protrusion 92 passes through the cutout portion 57b (the other cutout portion) with respect to the through hole 55. The cable 90 needs to be inserted, and the cable 90 cannot be inserted in the direction in which the first protrusion 91 is intended to pass through the notch 57b (the other notch). When it is about to be inserted in the right direction, it can be grasped before the flange portion 93 is inserted.
