A position detection sensor 118.

  The double-sided printing label 3 is supplied into the housing 111 from a supply port 111a provided in the housing 111 of the double-sided printing apparatus 110 with the front side label 5 facing upward, and the first thermal head 112 and the first platen roller 114 are supplied. And between the second thermal head 113 and the second platen roller 115.

  When the heating element of the first thermal head 112 is energized in this state, the surface-side label 5 which is a thermal medium is self-colored by the heat of the heating element and printing is performed. Further, when the heating element of the second thermal head 113 is energized, the back side label 4 which is a thermal medium is self-colored by the heat of the heating element and printing is performed.

  The inner side portion 5 c of the front surface side label 5 is used as a front surface printing region of the double sided printing label 3, and the central portion 4 f of the back surface side label 4 is used as the back surface printing region of the double sided printing label 3. In the front surface printing area of the double-sided printing label 3, for example, delivery destination information of the package 1 is printed. Further, in the back side printing area of the double-sided printing label 3, for example, information to be kept confidential such as the product name and the amount of money is printed.

  When the first platen roller 114 and the second platen roller 115 are rotated forward by the first platen drive motor 116 and the second platen drive motor 117, the double-sided printing label 3 is conveyed to the downstream side and provided in the housing 111. It is discharged from the discharge port 111b. The first platen roller 114 and the second platen roller 115 rotate in synchronism with each other so that the double-sided printing label 3 is not slackened or tensioned.

  The position detection sensor 118 detects a position detection eye mark printed in advance on the back surface side label 4 of the double-sided printing label 3 at a predetermined interval, and includes a first thermal head 112 and a second thermal head. This is used to detect the relative position of the double-sided printing label 3 with respect to 113. The controller 290 controls the operation of the first platen drive motor 116 and the second platen drive motor 117 according to the detection signal of the position detection sensor 118.

  The label issuing apparatus 100 includes a label peeling mechanism 120 that separates the single label tag 2 from the printed double-sided label 3.

  The label peeling mechanism 120 is disposed on the downstream side of the double-sided printing apparatus 110, peels the outer edge portion 4b of the back surface side label 4 from the front surface side label 5, and the front surface side label 5 and the inner side portion 4c of the back surface side label 4; This is a mechanism for separating the single-leaf tag label 2 constituted by the double-sided printing label 3.

  The label peeling mechanism 120 includes a label winder 121 that winds the outer edge 4b of the back side label 4 peeled from the front side label 5, and a winder drive that drives the label winder 121 via a belt, a gear, or the like. A peeling plate 123 that comes into contact with the back surface of the double-sided printing label 3 discharged from the double-sided printing apparatus 110 and peels the outer edge 4b of the back-side label 4 from the front-side label 5 and the peeling from the front-side label 5 Guide rollers 124 to 127 for guiding the outer edge portion 4 b of the rear surface side label 4 to the label winder 121. The guide roller 126 is driven by a motor (not shown) so as to feed the outer edge portion 4b of the back side label 4 sandwiched between the guide roller 127 and the guide roller 126.

  The label winder 121 includes a pair of rotating plates 121a and four winding shafts 121b extending across the pair of rotating plates 121a. The outer edge part 4b of the back surface side label 4 engages with the four winding shafts 121b and is wound between the two rotating plates 121a.

  The guide roller 126 and the label winder 121 are rotationally driven in both forward and reverse directions in synchronization with the first platen roller 114 and the second platen roller 115 of the duplex printing apparatus 110. Thereby, when the label winder 121 winds up the outer edge part 4b of the back surface side label 4, it does not occur that the double-sided printing label 3 or the outer edge part 4b of the back surface side label 4 is loosened or tensioned. It has become.

  When the outer edge portion 4 b of the back surface side label 4 is wound around the label winder 121, the outer edge portion 4 b is sequentially peeled from the front surface side label 5 by being bent at the front end position of the peeling plate 123. Even if the outer edge part 4b peels from the surface side label 5, the inner side part 4c of the back surface side label 4 does not peel from the surface side label 5, but is separated from the outer edge part 4b by the cut 4a. Thus, the tag label 2 having the front side label 5 and the inner side portion 4c of the back side label 4 is issued separately from the double-sided printing label 3.

  Next, the label sticking mechanism 200 for sticking the tag label 2 issued from the label issuing device 100 to the luggage 1 will be described.

  As shown in FIGS. 1 and 2, the label sticking mechanism 200 receives a tag mechanism 2 that transports a tag label 2 issued from the label issuing device 100, and a tag label 2 that is transported by the transport mechanism 210. And a pasting mechanism 240 for pasting to the head.

  The transport mechanism 210 is provided with a plurality (two) of transport conveyors 211 (transport units) arranged side by side. The transport conveyor 211 is a transport unit that transports the tag label 2 that is issued separately from the double-sided printing label 3 by the label peeling mechanism 120 to a delivery position to the sticking mechanism 240. Note that the number of transport conveyors 211 provided in the transport mechanism 210 is not limited to two, and is arbitrarily set according to the size of the label 2 and the like.

  The conveyor 211 includes a belt 212 for conveying the label 2, rollers 214 and 215 around which the belt 212 is wound, and a conveyor drive motor that drives the belt 212 via a belt, a gear, or the like. 213.

  The belt 212 circulates in synchronization with the first platen roller 114, the second platen roller 115, and the label winder 121 of the duplex printing apparatus 110. As a result, the tag label 2 issued separately from the double-sided printing label 3 is transferred from the label issuing device 100 to the transport conveyor 211 without delay.

  A label detection sensor 216 is provided in the vicinity of the conveyor 211. The label detection sensor 216 is a reflective photoelectric sensor that detects the presence or absence of the label 2. The controller 290 controls the operation of the transport conveyor 211 so as to transport the tag label 2 to the delivery position to the sticking mechanism 240 in accordance with the detection signal of the label detection sensor 216.

  The pressure-sensitive adhesive layer 5 e is exposed on the back surface of the tag label 2 because the outer edge portion 4 b of the back surface side label 4 is peeled from the front surface side label 5. In response to this, a release agent layer (not shown) is provided on the surface of the belt 212. This prevents the tag label 2 from sticking to the belt 212 via the adhesive layer 5e. Further, the adhesive of the adhesive layer 5e is prevented from adhering to the belt 212.

  The conveyor 211 may include a negative pressure generator that has a plurality of holes in the belt 212 and generates a negative pressure in each hole. In this case, the tag label 2 is conveyed while being attracted to the belt 212, thereby preventing the tag label 2 from slipping or being displaced on the belt 212.

  The transport mechanism 210 is provided with a push-up unit 220 that pushes up the tag label 2 transported by the transport conveyor 211 from the transport conveyor 211.

  As shown in FIG. 2, the push-up unit 220 includes a plurality (six blades) of blades 221 arranged side by side with the conveyor 211 and an actuator 222 that moves the blades 221 up and down.

  As shown in FIG. 6, the push-up portion 220 is provided with three sets of two blades 221 in one set. Each set composed of a set of two blades 221 is arranged so as to sandwich each conveyance conveyor 211 and is in contact with both sides and the center of the label 2.

  As shown in FIGS. 7 and 8, each blade 221 is fixedly attached to the push-up frame 225. The push-up frame 225 is driven in the vertical direction by the actuator 222.

  As a result, each blade 221 protrudes downward from the belt 212 of the conveyor 211 as shown in FIGS. 8 and 9A, and protrudes upward from the belt 212 of the conveyor 211 as shown in FIG. 9B. It moves up and down between the protruding position where the label 2 is lifted.

  The thin plate-like blade 221 is disposed so as to extend along the side portion of the transport conveyor 211 and to extend in the vertical direction (vertical direction).

  The blade 221 has a tip 221a extending linearly at the top thereof. The width T1 (see FIG. 6) of the tip 221a is set to be smaller than the width T5 (see FIG. 5) of the adhesive layer 5e of the tag label 2, and is in linear contact with the adhesive layer 5e.

  A release agent layer (not shown) is provided on the surface of the tip 221a. This prevents the tag label 2 from sticking to the blade 221 via the adhesive layer 5e. Further, the adhesive of the adhesive layer 5e is prevented from adhering to the blade 221.

  The two blades 221 are coupled via a plurality (two) of spacers 224. The two blades 221 have a predetermined interval. Specifically, the blade installation width T2 (see FIGS. 6 and 7) where the tips 221a of the two blades 221 are provided is set smaller than the suction width T3 (see FIGS. 6 and 7) of the suction pad 241 described later. Is done.

  Thus, the two blades 221 are disposed so as to face the suction pad 241. Note that the number of blades 221 facing the suction pad 241 is not limited to two, and is arbitrarily set according to the size of the suction pad 241 and the like.

  Further, the label detection sensor 216 for detecting the presence / absence of the tag label 2 described above may be provided so as to be disposed between the two blades 221 aligned with each other. In this case, the label detection sensor can be disposed so as to face the center of the label 2. Thereby, the label detection sensor 216 can accurately detect the presence / absence of the label 2 on the blade 221.

  As shown in FIGS. 7 and 8, the pasting mechanism 240 includes a plurality (eight) suction pads 241 (suction portions) for sucking the label 2, pipes 242 to which the suction pads 241 are connected, and each pipe. Elevating frame 245 to which 242 is attached. The pipe 242 is connected to a negative pressure generator via a pipe (not shown), and guides the negative pressure to the inside of the suction pad 241. The suction pad 241 is a suction portion that sucks the label 2 with a negative pressure. The number of suction pads 241 is not limited to eight, and can be arbitrarily set according to the size of the tag label 2 and the like.

  The suction pad 241 is formed of an elastic material such as rubber, for example. The suction pad 241 is elastically deformed by the negative pressure that sucks the label 2 and contracts in the axial direction (vertical direction).

  The suction pad 241 is formed in a cylindrical shape having a bellows-like cross-sectional shape, and has an annular suction surface 241 a that sucks the tag label 2. The diameter of the suction surface 241a is the suction width T3 for sucking the tag label 2. In addition, the suction pad 241 is not limited to this shape, and may be any one that elastically deforms and expands and contracts due to a pressure change generated inside thereof.

  As shown by a two-dot chain line in FIG. 6, the eight suction pads 241 are arranged so as to face the outer edge portion 5 b of the tag label 2.

  Further, a plurality (three or two) of suction pads 241 arranged in the left-right direction in FIG. 6 are arranged so as to face three sets of blades 221 extending in the longitudinal direction of the tag label 2 (left-right direction in FIG. 6). Is done.

  As shown in FIGS. 7 and 8, the sticking mechanism 240 includes a support portion 250 that supports the tag label 2 that is sucked by the suction pad 241. When the suction pad 241 sucks the tag label 2 and contracts, the support unit 250 supports the tag label 2 by contacting it. This restricts the tag label 2 from loosening between the suction pads 241.

  The support portion 250 includes a plurality (two) of elastic members 251 that abut on the label 2 that is attracted to the suction pad 241, and a plurality (two) of brackets 253 that attach the elastic members 251 to the lifting frame 245. .

  As shown by a two-dot chain line in FIG. 6, the two elastic members 251 are arranged so as to extend between the suction pads 241 arranged in three rows in the longitudinal direction of the tag label 2 (left-right direction in FIG. 6). Note that the number of elastic members 251 is not limited to two, and is arbitrarily set according to the number of rows of suction pads 241.

  The block-like elastic member 251 has a cubic outer shape and has a support surface 251a extending in the horizontal direction. The support surface 251 a is provided so as to face the tag label 2, and comes into contact with the tag label 2 attracted to each suction pad 241.

  The elastic member 251 is formed of a porous material (sponge) having a large number of bubbles formed by foaming rubber such as ethylene propylene rubber (EDPM).

  The elastic member 251 is attached to be attached to the lower surface of the bracket 253. The bracket 253 is fastened to the lifting frame 245 via a plurality (two) of bolts 254. The attachment position of the elastic member 251 with respect to the suction pad 241 is adjusted by changing the position where the bracket 253 is fastened to the lifting frame 245.

The elastic member 251 is attached so as to satisfy the following conditions.
In a non-adsorption state (free state) in which the suction pad 241 is not contracted by negative pressure, the suction surface 241a of the suction pad 241 is lowered (spaced away) by a predetermined amount with respect to the support surface 251a of the elastic member 251. To position.
In the suction state (elastic deformation state) in which the suction pad 241 is contracted by negative pressure, the suction surface 241a of the suction pad 241 is substantially at the same height as the support surface 251a of the elastic member 251. Thereby, the adsorption surface 241a and the support surface 251a are disposed so as to extend on the same straight line.

  The suction pad 241 is contracted by a predetermined amount (for example, about 2 mm) by the negative pressure that sucks the tag label 2, so that the suction surface 241 a that sucks the tag label 2 is located below (separated from) the support surface 251 a of the elastic member 251. ) Is set to at least a position that is at the same height as the support surface 251a of the elastic member 251.

  As shown in FIG. 6, a label detection sensor 248 is provided between the two elastic members 251. The label detection sensor 248 is a reflective photoelectric sensor that detects the presence or absence of the label 2. The controller 290 determines that there is the tag label 2 in accordance with the detection signal of the label detection sensor 248, and operates the moving mechanism 230 to attach the tag label 2 to the package 1 as will be described later. When there is no tag label 2, the operation of the moving mechanism 230 is stopped.

  As shown in FIG. 1, the moving mechanism 230 is movable along the fixed frame 231, a horizontal rail 232 extending in a horizontal direction perpendicular to the conveying direction of the roller conveyor 280 on the fixed frame 231, and the horizontal rail 232. A moving body 233 provided, an actuator (not shown) that drives the moving body 233, a vertical rail 234 extending in the vertical direction from the moving body 233, a lifting frame 245 that is vertically movable along the vertical rail 234, and a lifting frame 245 And an actuator not shown.

  The moving body 233 moves in the horizontal direction orthogonal to the conveying direction of the roller conveyor 280 by the actuator. The moving body 233 includes a label receiving position where the sticking mechanism 240 is located on the transport mechanism 210 (two-dot chain line in FIG. 1), and a label sticking position where the sticking mechanism 240 is located on the roller conveyor 280 (solid line in FIG. 1). , Move between. The elevating frame 245 moves up and down with respect to the moving body 233 by an actuator.

  Thereby, the sticking mechanism 240 moves up and down at each of the position where the tag label 2 is received from the blade 221 and the position where the tag label 2 is stuck on the load 1 on the roller conveyor 280.

  The roller conveyor 280 includes a stopper (not shown), and stops the luggage 1 at the label application position until the application of the tag label 2 to the luggage 1 is completed. When the application of the tag label 2 to the package 1 is completed, the stopper of the roller conveyor 280 is released, and the package 1 is conveyed downstream.

  Next, with reference to FIG. 9A to FIG. 9F, an operation for attaching the label 2 to the luggage 1 in the label attaching mechanism 200 will be described.

  First, as shown in FIG. 9A, the transport conveyor 211 circulates the belt 212 and transports the tag label 2 placed on the belt 212 to the delivery position of the sticking mechanism 240.

  At this time, the blade 221 is in a retracted position lowered below the belt 212 and does not interfere with the transported label 2.

  Subsequently, as shown in FIG. 9B, the blade 221 rises to the protruding position. As a result, the tip 221a of the blade 221 protrudes above the belt 212, and the tag label 2 is lifted away from the belt 212.

  Subsequently, as shown in FIG. 9C, each suction pad 241 of the sticking mechanism 240 is lowered.

  At this time, since the suction surface 241 a of each suction pad 241 is below the support surface 251 a of the elastic member 251, each suction pad 241 comes into contact with the tag label 2 before the elastic member 251, and the inside of the suction pad 241. The label 2 is adsorbed by the negative pressure introduced to

  When each suction pad 241 sucks the tag label 2, each suction pad 241 sandwiches the tag label 2 between the tips 221 a of the blades 221. The tag label 2 is supported in linear contact with the tip 221a of each blade 221.

  At this time, since the belt 212 is below the tip 221a of the blade 221, the pressure-sensitive adhesive layer 5e of the tag label 2 is prevented from being pressed against the belt 212.

  Thus, when each suction pad 241 sucks the label 2, each suction pad 241 contracts due to negative pressure as shown in FIG. 9D, and the suction surface 241 a of each suction pad 241 is substantially the same as the support surface 251 a of the elastic member 251. Come to the same height. As a result, the label 2 adsorbed by each suction pad 241 extends straight by coming into contact with the support surface 251a of each elastic member 251 extending along the same straight line along with the suction surface 241a of the suction pad 241. Supported by

  Subsequently, the moving body 233 moves from the label receiving position (two-dot chain line in FIG. 1) to the label attaching position (solid line in FIG. 1).

  Subsequently, as shown in FIG. 9E, the tag label 2 is affixed to the luggage 1 as the affixing mechanism 240 is lowered.

  At this time, the suction surface 241a of the suction pad 241 extending on the same straight line and the support surface 251a of the elastic member 251 press the tag label 2. The tag label 2 is affixed to the adherend surface (upper surface) of the luggage 1 without wrinkles in a state of extending straight.

  At this time, if there is a undulation such as a step or an inclination on the surface to be adhered of the luggage 1, each suction pad 241 and each elastic member 251 elastically deforms following the shape of the surface to be adhered of the luggage 1. . In this way, the label 2 is stuck via the pressure sensitive adhesive layer 5e by pressing the pressure sensitive adhesive layer 5e against the sticking surface of the load 1 in a wide range.

  Finally, as shown in FIG. 9F, after the sticking mechanism 240 is raised, the moving body 233 moves to the label receiving position (two-dot chain line in FIG. 1), and shifts to the operation of sticking the next tag label 2.

  Next, a comparative example shown in FIGS. 10A, 10B, and 10C will be described. The sticking mechanism 240 according to this comparative example does not include the support portion 250, and a space is provided between the suction pads 241.

  FIG. 10A shows an operation in which each suction pad 241 sucks the tag label 2. Since there is no portion for supporting the tag label 2 between the suction pads 241, when there is a variation in the operation of the suction pads 241 to suck the tag label 2, the tag label 2 sucked by the suction pads 241 is used. Does not extend straight and slack A occurs between the suction pads 241. In this case, as shown in FIG. 10B, the tag label 2 is stuck to the luggage 1 with the slack A caused by the lowering of the sticking mechanism 240. For this reason, as shown in FIG.

  In contrast to the comparative example, in the present embodiment, as described above, the tag label 2 attracted to each suction pad 241 is supported in a state of being in contact with the support surface 251a of each elastic member 251 and extending straight. This prevents the tag label 2 from being wrinkled.

  Next, the effect of this embodiment will be described.

  According to the present embodiment, the label sticking device 10 receives the tag label 2 transported by the transport mechanism 210 that transports the label label 2 (label) and the transport mechanism 210, and pastes it on the package 1 (adherent). A pasting mechanism 240.

  The affixing mechanism 240 includes a plurality of suction pads 241 (suction portions) that suck the tag label 2 by negative pressure, and a tag label 2 provided between the plurality of suction pads 241 and sucked by the plurality of suction pads 241. And a support part 250 for supporting the above.

  Based on the above configuration, the tag label 2 sucked by the plurality of suction pads 241 is suppressed from being loosened by being supported by the support portion 250. For this reason, it is possible to prevent wrinkles from approaching the label 2 attached to the luggage 1. As a result, when the package 1 is shipped, the characters and barcodes printed on the tag label 2 are accurately read. Further, it is possible to prevent the tag label 2 from being broken.

  The support part 250 includes an elastic member 251 that is elastically deformed by an external force.

  Based on the above configuration, when the tag label 2 is attached to the luggage 1, the elastic member 251 contracts due to the reaction force received from the luggage 1 and presses the tag label 2 against the luggage 1. Thereby, the adhesive layer 5e of the tag label 2 is brought into close contact with the package 1, and the tag label 2 is reliably attached.

  The support portion 250 is not limited to the above-described configuration, and may be configured by a support member that is not elastically deformed by an external force and an air cylinder that supports the support member so as to advance and retract. In this case, when the tag label 2 is affixed to the luggage 1, the air cylinder contracts due to the reaction force received from the luggage 1, and a pressing force for affixing the tag label 2 to the luggage 1 is applied.

  The elastic member 251 is made of a porous material (sponge) having a large number of bubbles.

  Based on the above configuration, when there is undulation on the surface of the load 1 to which the label 1 is attached, the elastic member 251 is elastically deformed so that the porous material (sponge) contracts, and the label 2 is attached to the load 1. A sufficient pressing force can be applied.

  The porous material (sponge) is obtained by foaming rubber.

  Based on the above configuration, both stretchability and durability can be secured by foam molding of rubber. In addition, the porous material (sponge) may use another synthetic resin.

  Further, the suction pad 241 has a suction surface 241 a that comes into contact with and attracts the tag label 2, and the support portion 250 has a support surface 251 a that comes into contact with the tag label 2. When the suction pad 241 sucks the label 2, the suction surface 241 a moves from the position where the suction surface 241 a protrudes toward the transport mechanism 210 from the support surface 251 a to at least a position extending linearly with the support surface 251 a.

  Based on the above configuration, before the suction pad 241 sucks the tag label 2, the suction surface 241 a protrudes below the support surface 251 a, so that the operation of the suction pad 241 sucking the tag label 2 is obstructed by the support unit 250. Not. And the suction pad 241 is raised to a position where the suction surface 241a is at least approximately the same height as the support surface 251a by contracting due to the negative pressure that sucks the tag label 2. For this reason, the tag label 2 adsorbed on the adsorption surface 241a extends linearly by coming into contact with the support surface 251a, and after that, the tag label 2 attached to the luggage 1 (adhered body) is wrinkled. Can be prevented.

  The transport mechanism 210 includes a transport conveyor 211 (transport section) that transports the tag label 2 and a push-up unit 220 that pushes up the tag label 2 transported by the transport conveyor 211 from the transport conveyor 211.

  Based on the above configuration, the tag label 2 conveyed by the conveyor 211 is received by the sticking mechanism 240 while being pushed up from the conveyor 211 by the push-up portion 220. Thereby, the adhesive layer 5e of the tag label 2 is not pressed against the conveyor 211. For this reason, it is suppressed that the adhesive layer 5e of the tag label 2 adheres to the conveyance conveyor 211, and the delivery of the tag label 2 is performed smoothly. And since the adhesive of the adhesive layer 5e is prevented from adhering to the conveyance conveyor 211, the state where the conveyance conveyor 211 conveys the tag label 2 smoothly is maintained.

  The suction pad 241 is provided at a position facing the push-up portion 220.

  Based on the above configuration, the suction pad 241 is sucked so as to sandwich the label 2 between it and the push-up portion 220. Thereby, in the sticking mechanism 240, the tag label 2 is reliably sucked by the suction pad 241.

  Further, the push-up unit 220 includes a blade 221 that comes into linear contact with the tag label 2.

  Based on the above configuration, the blade 221 linearly contacts the pressure-sensitive adhesive layer 5e of the tag label 2, and the contact area with the pressure-sensitive adhesive layer 5e decreases, so the tag label 2 is bonded via the pressure-sensitive adhesive layer 5e. It is prevented. Thereby, it is performed smoothly that the sticking mechanism 240 receives the tag label 2.

  The blade 221 is not limited to the above-described configuration, and has a configuration in which a plurality of pin-shaped protrusions are arranged at intervals to contact the pressure-sensitive adhesive layer 5e of the label 2 in a dotted manner. Also good. In this case, since the contact area with the pressure-sensitive adhesive layer 5e is reduced, the blade 221 can effectively prevent the blade 221 from sticking to the pressure-sensitive adhesive layer 5e.

  Further, the push-up portion 220 is disposed so that the plurality of blades 221 face the suction pad 241 with the label 2 interposed therebetween.

  Based on the above configuration, the tag label 2 is supported across the plurality of blades 221, so that the occurrence of bending or the like at a portion facing the suction pad 241 can be suppressed. By attracting the suction pad 241 with the tag label 2 sandwiched between the plurality of blades 221, the tag label 2 is reliably sucked.

  The tag label 2 has an adhesive layer 5e that adheres to the luggage 1, and the suction pad 241 is disposed so as to adsorb the surface of the tag label 2 opposite to the adhesive layer 5e.

  Based on the above configuration, when the tag label 2 is affixed to the package 1, the suction pad 241 presses the surface of the tag label 2 opposite to the adhesive layer 5e. As a result, the label 2 is reliably attached to the luggage 1 by the pressure-sensitive adhesive layer 5 e being pressed against the luggage 1 by the suction pad 241.

  In addition, the pasting mechanism 240 is configured to receive the tag label 2 from the transport mechanism 210 by moving up and down above the transport mechanism 210 and to paste the tag label 2 onto the package 1 by moving up and down above the load 1.

  Based on the above configuration, the label sticking apparatus 10 receives the tag label 2 from the transport mechanism 210 and sticks the tag label 2 to the package 1 with certainty.

  The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment. Absent.

  This application claims the priority based on Japanese Patent Application No. 2006-037963 for which it applied to the Japan Patent Office on February 29, 2016, The entire content of this application is integrated in this specification by reference.
