In fact in this automated teller machine, if user inserts notes here to Banknote deposting/drawing out mouth when depositing, then differentiate the bank note after dropping into by discriminating portion, and will differentiate as the bank note containing of normal bank note is in temporary transient storage unit, on the other hand, make to be identified as the bank note should not concluded the business return to Banknote deposting/drawing out mouth and return to user.At this, if determine amount deposited by user, then by discriminating portion, the face amount of the bank note being accommodated in temporary transient storage unit is differentiated again, according to the face amount after discriminating to each bill storage keeping bank note.

Further, in this automated teller machine, if user specifies withdraw funds when withdrawing the money, then send the bank note corresponding to withdraw funds from each bill storage to transport road and differentiated by discriminating portion, then making this bank note be collected in depositing and drawing port.

And then, in automated teller machine, the monitoring sensor being used for monitoring with or without bank note etc. in the position of bank note, the transporting velocity of bank note, bill storage is arranged at assigned position.This monitoring sensor is configured to comprise one group of luminescence sensor and photosensitive sensor, and it is arranged opposite that this luminescence sensor and photosensitive sensor such as separate predetermined distance ground.

At this, for the installing mechanism of such monitoring sensor, monitoring sensor to be installed on the situation to the conveying guiding piece that the conveying of bank note guides, Figure 33 to Figure 35 is utilized to be described.

In addition, except kind this point different of sensor, the luminescence sensor forming monitoring sensor is formed as substantially identical structure with photosensitive sensor.Therefore, mainly the installation of luminescence sensor is described at this.

As shown in figure 33, luminescence sensor 100 has the sensor housing 101 of lengthwise rectangular shape, has substrate 102 at this sensor housing 101 internal fixtion.This substrate 102 is provided with sensor element (i.e. light-emitting component) 103 and the connector 104 be connected, only has the terminal part of connector 104 to expose from the lower surface 101a of sensor housing 101.

And then have the columned light path portion 105 be formed as towards the light path of sensor element 103 the front surface of sensor housing 101 is projecting, the optical axis in this light path portion 105 is consistent with the optical axis of the sensor element 103 in sensor housing 101.

And then, at left surface 101c and the right flank 101d of sensor housing 101, respectively near the upper surface 101e of sensor housing 101 with lower surface 101a near two positions, place projectingly have locking protrusion 106.

The front surface 106a of locking protrusion 106 is formed as taper surface (dip plane), on the other hand, its rear surface 106d is formed as the normal surface of two sides 101c, 101d relative to sensor housing 101, thus entirety is formed as the sharp-pointed wedge shape in front.

On the other hand, as shown in figure 34, the conveying guiding piece 110 becoming the installation place of luminescence sensor 100 is formed by having flexible synthetic resin, embedded hole 111 through for the rear surface 110b of the opposition side of the front surface 110a and this front surface 110a that become guide surface is formed at the position of regulation.This embedded hole 111 is formed as cylindric roughly the same with the external diameter in light path portion 105 of diameter, and when sensor installation, this embedded hole 111 is chimeric with the light path portion 105 of luminescence sensor 100.In addition, particularly through hole is called hole at this.

Further, conveying guiding piece 110 rear surface 110b and on the left and right directions of embedded hole 111, have parallel a pair holding plate 112 across this embedded hole 111 is projecting.Holding plate 112 about this forms as one with conveying guiding piece 110.

Holding plate 112 about this has elasticity, thus can near and away from the direction elastic deformation of respective front end.

And then, the convex strip portions 112a inwards given prominence to along its edge is formed in the respective front end of the holding plate 112 of left and right.

The interval of convex strip portions 112a of the left and right that the respective front end of the holding plate 112 in left and right is arranged and the transverse width of the sensor housing 101 of luminescence sensor 100 roughly equal, when sensor installation, the convex strip portions 112a of left and right sandwiches the sensor housing 101 of luminescence sensor 100 from the left and right sides, abut thus with the rear surface 106b of locking protrusion 106.

When luminescence sensor 100 is installed on this conveying guiding piece 110 by reality, under the state making the light path portion 105 of luminescence sensor 100 opposed with the embedded hole 111 of conveying guiding piece 110, between the holding plate 112 about luminescence sensor 100 being pressed into from the 110b side, rear surface of conveying guiding piece 110.

Now, be separately positioned on the front surface 106a of the left surface 101c of the sensor housing 101 of luminescence sensor 100 and the locking protrusion 106 of right flank 101d, first abut with the convex strip portions 112a of the holding plate 112 being arranged at left and right respectively.

If from this state further press-in luminescence sensor 100, then the interval between the holding plate 112 widening left and right by the front surface 106a pressing of locking protrusion 106, to make the holding plate 112 about this away from the convex strip portions 112a of respective front end.

If be pressed into further, then the convex strip portions 112a of left and right can cross locking protrusion 106.Now, the close masterpiece of the convex strip portions 112 of respective front end of the holding plate 112 of left and right is made to be holding plate 112 about recuperability acts on this.Thus, as shown in figure 35, the convex strip portions 112a of left and right sandwiches the sensor housing 101 of luminescence sensor 100 from the left and right sides, and abuts with the rear surface 106b of locking protrusion 106 and engage, and keeps sensor housing 101 thus.

Further, now, the light path portion 105 of luminescence sensor 100 is chimeric with the embedded hole 111 of conveying guiding piece 110, thus the position of this luminescence sensor is fixed.Like this, luminescence sensor 100 is fixed and held in conveying guiding piece 110.

In addition, although eliminate explanation at this, on the conveying guiding piece of opposition side, the installing mechanism of the photosensitive sensor same with the installing mechanism of luminescence sensor 100 is in fact provided with across transport road.

In the past, in the above described manner monitoring sensor is installed on conveying guiding piece 110 (such as with reference to patent documentation 1).

But when above-mentioned existing installing mechanism, when mounted, if when being applied with the power of the degree exceeding its deformable scope because of error to the holding plate 112a of elastically deformable, then recuperability can disappear or cause this holding plate 112a damaged.

In this case, holding plate 112a must being changed, as mentioned above, because holding plate 112a and conveying guiding piece 110 form as one, therefore in order to change holding plate 112a, each conveying guiding piece 110 must be changed, thus can consuming cost.

To this, although also contemplate by holding plate 112a being made the separate part that can be installed on conveying guiding piece 110, can only change holding plate 112a, in this case, can increase parts number of packages, result is tantamount to consuming cost.

Summary of the invention

The present invention, on the basis considering above problem, proposes the sensor that can reduce costs further compared with the past and monitoring arrangement.

In order to solve such problem, be provided with in sensor of the present invention: the roughly housing of rectangular shape and the sensor element that is fixed in housing, can a pair fastener of elastic deformation form as one in these two sides, another side of a side of housing and opposition side and housing, wherein, above-mentioned a pair fastener engages with the installation portion of the installation place becoming housing, thus housing is locked to this installation portion.

And, be provided with in monitoring arrangement of the present invention: the sensor monitoring object, its housing with roughly rectangular shape and the sensor element be fixed in this housing, can a pair fastener of elastic deformation form as one in these two sides, another side of a side of this housing and opposition side and housing, wherein, above-mentioned a pair fastener engages with the installation portion of the installation place becoming housing, thus housing is locked to this installation portion; Installation portion, it becomes the installation place of housing; Control part, it controls sensor.

Thus, when sensor installation, even if make fastener damaged because error causes the power exceeding the scope that can be out of shape to put on the fastener of sensor, also only more emat sensor, and, the housing of fastener and sensor forms as one, thus just can suppression component number of packages without the need to other installation parts etc.

[installing mechanism of 1-2. monitoring sensor]

At this, for the installing mechanism of such monitoring sensor, to be installed on situation to the conveying guiding piece that the bank note by transport road 12 guides by monitoring by the bank note sensor of the bank note of transport road 12, Fig. 3 and Fig. 4 is utilized to be described.

As shown in Figure 3, luminescence sensor 20 has the sensor housing 21 of the roughly rectangular shape of lengthwise.This sensor housing 21 is formed by synthetic resin, is fixed with substrate 22 therein.And then at the connector 24 that this substrate 22 is provided with sensor element (i.e. light-emitting component) 23 and connects, the terminal part of connector 24 is exposed from the lower surface 21a of sensor housing 21.

And then projecting above the front surface 21b of sensor housing 21 have columned light path portion 25, and it is consistent with the optical axis of the sensor element 23 in sensor 21 that this light path portion 25 is arranged to optical axis.

And then, at left surface 21c and the right flank 21d of sensor housing 21, be formed with recess 26 in a part of central authorities surperficial 21a slightly on the lower respectively, and be formed with arm 27 in the mode being embedded in this recess 26.

The arm 27 of left and right is formed as, from the rear end side of recess 26 tabular of cross section roughly in L-shaped that extend of side forward, forming as one with the mode of the spaced apart at gaps at the end in the front of arm 27 and recess 26 and sensor housing 21 respectively.

And then the arm 27 about this has elasticity, can make respectively thus front end towards near and the end away from recess 26 direction (that is, the front end of the arm 27 of left and right adjacent to each other and away from direction) elastic deformation.

And then the respective front end of the arm 27 about this is formed with prominent locking protrusion 28 laterally.

The front surface 28a of this locking protrusion 28 is formed as taper surface (dip plane), and on the other hand, its rear surface 28b is formed as the normal surface of the side 27a relative to arm 27, thus entirety is formed as the sharp-pointed wedge shape in front.

In addition, when the arm 27 of left and right is not applied to the state of external force, locking protrusion 28 is only had to give prominence to from the left surface 21c of sensor housing 21 and right flank 21d.

On the other hand, as shown in Figure 4, conveying guiding piece 30 is formed by synthetic resin, embedded hole 31 through for the rear surface 30b of the front surface 30a and opposition side thereof that become the guide surface of transport road 12 side is formed at the position of regulation.This embedded hole 31 is formed as cylindric roughly the same with the external diameter in the light path portion 25 of luminescence sensor 20 of diameter, and when sensor installation, this embedded hole 31 is chimeric with the light path portion 25 of luminescence sensor 20.

Further, conveying guiding piece 30 rear surface 30b and in the below of embedded hole 31, across from the center of this embedded hole 31 to immediately below the imaginary line L that extends and projectingly have parallel a pair holding plate 32.Holding plate 32 about this forms as one with conveying guiding piece 30.

Further, the holding plate 32 of left and right is formed as making its interval substantially equal with the transverse width of the sensor housing 21 of optical sensor 20, when sensor installation, sandwiches arm 27 part of sensor housing 21 from the left and right sides.

Further, the holding plate 32 about this divides at the root of the face of respective inner side (also calling it as medial surface) 32a respectively and is formed with chimeric cave 33.

Chimeric cave about this 33 in roughly rectangular shape, and is formed as the size consistent with the locking protrusion 28 of the arm 27 being formed in luminescence sensor 27, and when sensor installation, the chimeric cave 33 about this is chimeric with the locking protrusion 28 of left and right.

In addition, although eliminate explanation at this, but in fact at the conveying guiding piece of the opposition side across transport road 12, the mode opposed with luminescence sensor is provided with photosensitive sensor, is also provided with the installing mechanism of the photosensitive sensor identical with the installing mechanism structure of luminescence sensor 20 in this position.

[1-3. action and effect]

With in said structure, when luminescence sensor 20 being installed on conveying guiding piece 30, as shown in Figure 4, under the state making the light path portion 25 of luminescence sensor 20 opposed relative to the embedded hole 31 of conveying guiding piece 30, between the holding plate 32 about the sensor housing 21 of luminescence sensor 20 being pressed into from the 30b side, rear surface of conveying guiding piece 30.

Now, at the front surface 28a of the locking protrusion 28 of the left and right that the arm 27 of sensor housing 21 is formed, first abut with the edge of the front end face 32b of the holding plate 32 of left and right.

If be pressed into sensor housing 21 further from this state, the locking protrusion 28 being then formed at the front end of the arm 27 of left and right is pressed against the holding plate 32 of left and right, the front end of the arm 27 of left and right is out of shape in the mode at the end of the recess 26 of the left and right near sensor housing 21 thus, and sensor housing 21 is pressed between the holding plate 32 of the left and right of conveying guiding piece 30.

As shown in Fig. 5 and Fig. 6 (cut-open view), further press-in sensor housing 21, the locking protrusion 28 of the left and right of sensor housing 21 is made to arrive the chimeric cave 33 of the left and right formed at the holding plate 32 of the left and right of conveying guiding piece 30, if locking protrusion 28 is overall and chimeric cave 33 is fitted together to, then respective front end is made to be the arm 27 that recuperability acts on left and right away from the masterpiece at the end of the recess 26 of sensor housing 21.

Its result, the arm 27 of left and right returns to original shape respectively, and respective side 27a abuts with the medial surface 32a of the holding plate 32 of left and right.

Further, now, the rear surface 28b of respective locking protrusion 28 of the arm 27 of left and right abuts with wall (also the calling it as locking surface) 33a of the rear end side in the chimeric cave 33 of the holding plate 32 of left and right.Thus, sensor housing 21 engaged and remain between holding plate 32.

And then now, thus position of this luminescence sensor 20 chimeric with the embedded hole 31 of conveying guiding piece 30, the light path portion 25 of luminescence sensor 20 is fixed.Like this, luminescence sensor 20 is fixed and held in conveying guiding piece 30.

Like this, luminescence sensor 20 is installed in conveying guiding piece 30.

Like this, in the installing mechanism of the first embodiment, in the mode can carrying out elastic deformation, a pair arm 27 formed as one with sensor housing 21 is arranged at two sides 21c, 21d of the sensor housing 21 of luminescence sensor 20, and then forms locking protrusion 28 in the front end of this arm 27.

And then, arm 27 part of sensor housing 21 is sandwiched between the two pieces of holding plates 32 being arranged at conveying guiding piece 30, and the locking protrusion 28 of the arm 27 of left and right is fitted together to the chimeric cave 33 of the medial surface 32a being formed at two pieces of holding plates 32, thus sensor housing 21 engaged and remain between two holding plates 32.

Thus, when luminescence sensor 20 being installed on conveying guiding piece 30, even if the power exceeding deformable scope put on luminescence sensor 20 because of error thus cause arm 27 damaged, also luminescence sensor 20 can only be changed, compared with the situation that the conveying guiding piece 30 in the past like that changing large-scale and costliness is own, can reduce costs.

Further, arm 27 forms as one with the sensor housing 21 of luminescence sensor 20, thus without the need to the parts etc. of other installation, thus can suppression component number of packages.

Further, by being formed as the shape only making locking protrusion 28 give prominence to from left surface 21c and right flank 21d, sensor housing 21 can be made thus to realize the miniature dimensions with existing sensor housing equal extent.

And then, as long as make the holding plate 32 of conveying guiding piece 30 protrude the chimeric cave 33 that can form the size consistent with the locking protrusion 28 of arm 27 from the rear surface 30b of conveying guiding piece 30, with in the past like that holding plate with the roughly the same thickness of the sensor housing of luminescence sensor from compared with the situation of carry rear surface of guiding piece to give prominence to, can overhang be reduced.In addition, the holding plate 32 of guiding piece 30 is carried to become the easy shape being only formed with chimeric cave 33.

In fact, when making the mould of such conveying guiding piece 30, the locking surface 33a in chimeric cave 33 becomes (undercut) at the bottom of hole, compared with existing conveying guiding piece, as mentioned above, because overhang is little and shape is simple and easy, therefore, it is possible to do one's utmost to prevent from using the mold structures such as slide mechanism to complicate, or holding plate 32 cannot be formed because carrying the shape of guiding piece 30.

According to above structure, when luminescence sensor 20 being installed on conveying guiding piece 30, even if the power exceeding deformable scope degree put on because of error the arm 27 of luminescence sensor 20 thus cause arm 27 damaged, also luminescence sensor 20 can only be changed, and, arm 27 forms as one with the sensor housing 21 of luminescence sensor 20, thus without the need to the parts etc. of other installation, thus can suppression component number of packages.Like this, compared with the past, can reduce costs further.

[2. the second embodiment]

Next the second embodiment is described.In this second embodiment, the structure of the installing mechanism of monitoring sensor and the different of the first embodiment.

In addition, because the structure etc. of the automated teller machine 1 as the part beyond the installing mechanism of monitoring sensor is identical with the first embodiment, therefore can with reference to the first embodiment.Thus, mainly the installing mechanism of monitoring sensor is described at this.

In this second embodiment, not monitoring sensor is installed on conveying guiding piece 30, but is installed on the bracket of the sheet metal that cannot form holding plate 32, utilize Fig. 7 and Fig. 8 to be described as example.In addition, in Fig. 7 and Fig. 8, identical Reference numeral is marked to Fig. 3 something in common.

In addition, even if in this case, except kind this point different of sensor, the luminescence sensor forming monitoring sensor is formed as substantially identical structure with photosensitive sensor.Therefore, mainly the installation of luminescence sensor is described at this.

As shown in Figure 7, luminescence sensor 40 has the sensor housing 41 of the roughly rectangular shape of lengthwise.This sensor housing 41 is formed by synthetic resin, is fixed with substrate 22 therein.And then at the connector 24 that this substrate 22 is provided with sensor element (i.e. light-emitting component) 23 and connects, the terminal part of connector 24 is exposed from the lower surface 41a of sensor housing 41.

And then projecting above the front surface 41b of sensor housing 41 have columned light path portion 25, and it is consistent with the optical axis of the sensor element 23 in sensor 41 that this light path portion 25 is arranged to optical axis.

And then, at left surface 41c and the right flank 41d of sensor housing 41, respectively central authorities slightly on the lower surperficial 41a be partially formed recess 26, and be formed with the arm 27 identical with the first embodiment in the mode being embedded in this recess 26.

And then the respective front end of the arm 27 about this is formed with the locking protrusion 28 identical with the first embodiment.

In addition, three bearing surfaces 42 (42a, 42b, 42c) are formed at the left surface 41c of sensor housing 41 and right flank 41d between arm 27 and the upper surface 41e of sensor housing 41, these three bearing surfaces 42 are parallel from the front surface of sensor housing 41 and different with distance between front surface 41b, and from upper surface 41e side, are formed as stepped in the mode of left surface 41c and right flank 41d a part being excised according to the order from small to large of the distance between front surface 41b.

In addition, these three bearing surfaces 42 (42a, 42b, 42c) lay respectively at the position more more rearward than the rear surface 28b of locking protrusion 28.In addition, above-mentioned three bearing surfaces 42 (42a, 42b, 42c) will be described in detail below, when sensor installation, become the face abutted with the protuberance of bracket side, and distance separately and between the rear surface 28b of locking protrusion 28 is different, thus can sandwich between the rear surface 28b of locking protrusion 28 and the three kinds of brackets keeping thickness different.

And, the transverse width of above-mentioned three bearing surfaces 42 (42a, 42b, 42c) is fully shorter than the transverse width of the front surface 41b of sensor housing 41, in fact, even if be formed with above-mentioned three bearing surfaces 42 (42a, 42b, 42c), compared with the sensor housing 21 of the first embodiment, the size of sensor housing 41 is also almost constant.

And then, sensor housing 41 upper surface 41e and be formed with upward outstanding locking protrusion 43 at the middle body of its front end.Locking protrusion 28 shape and the size of this locking protrusion 43 and arm 27 are substantially identical, the front surface 43a of this locking protrusion 43 is formed as taper surface (dip plane), on the other hand, its rear surface 43b is formed as the normal surface of the upper surface 41e relative to sensor housing 41, thus entirety is formed as the sharp-pointed wedge shape in front.

On the other hand, as shown in Figure 8, bracket 50 is made up of the sheet metal of specific thickness, and is formed embedded hole 51 through for the rear surface 50b of front surface 50a and opposition side thereof.This embedded hole 51 with from the shape of the profile during sensor housing 41 of forward observation luminescence sensor 40 and size substantially identical, when sensor installation, this embedded hole 51 is chimeric with the sensor housing 41 of luminescence sensor 40.

Further, be formed with protuberance 52 at the left wall 51a of this embedded hole 51 and the respective central authorities position slightly by the top of right wall 51b, this protuberance 52 gives prominence to the inside in opposed mode and thickness is identical with bracket 50.

The protuberance 52 of above-mentioned left and right positions as follows: when sensor installation, in three bearing surfaces 42 (42a, 42b, 42c) of the left surface 41c and right flank 41d that are formed at sensor housing 41, abut with the bearing surface 42c that the rear surface 52a of protuberance 52 is corresponding with the thickness of bracket 50.

Further, the lower end side of embedded hole 51 and the shape opening accordingly of connector 24, when this embedded hole 51 is chimeric with the sensor housing 41 of luminescence sensor 40, not stop the connector 24 exposed from the lower surface 41a of sensor 41.

In addition, although eliminate explanation at this, in fact photosensitive sensor is arranged on the position opposed with luminescence sensor 40, is also provided with the bracket that the structure photosensitive sensor identical with bracket 50 is installed in this position.

[2-2. action and effect]

In above structure, when luminescence sensor 40 is installed on bracket 50, as can be seen from figures 8 and 9, make the sensor housing 41 of luminescence sensor 40 opposed with the embedded hole 51 of bracket 50 and from the 50b side, rear surface of bracket 50, this sensor housing 41 is inserted this embedded hole 51 under the state forwards tilted.

Now, under the state making sensor housing 41 forwards tilt, the locking protrusion 43 being formed at the upper surface 41e of sensor housing 41 is inserted into the embedded hole 51 of bracket 50 till the embedded hole running through bracket 50.In addition, now, the bottom of sensor housing 41 is in the state being not yet inserted into embedded hole 51.

If the locking protrusion 43 of sensor housing 41 has run through the embedded hole 51 of bracket 50, then next as shown in Fig. 9 (A), make the rear surface card of locking protrusion 43 be hung on the edge of the upper wall surface 51c of the embedded hole 51 of bracket 50, make sensor housing 41 be that axial its direction tilting to disappear that makes rotates with this edge.

So the front surface 28a of the locking protrusion 28 that the arm 27 in the left and right of sensor housing 41 is formed abuts with the left wall 51a of the embedded hole 51 of bracket 50 and the edge of right wall 51b.

If be pressed into sensor housing 41 further and make it rotate from this state, the locking protrusion 28 that the front end of the arm 27 then in left and right is formed is pressed against the left wall 51a of embedded hole 51 and right wall 51b, the front end of the arm 27 of left and right is out of shape in the mode at the end of the recess 26 near left and right thus, and the bottom of sensor housing 41 is inserted into embedded hole 51.

If make it further rotate, as shown in Fig. 9 (B), the locking protrusion 28 of the arm 27 of the left and right of sensor housing 41 runs through embedded hole 51, sensor 41 is overall chimeric with embedded hole 51, then the respective front end of the arm 27 about now making is the arm 27 about recuperability acts on this away from the masterpiece at the end of the recess 26 of sensor housing 41.Its result, the arm 27 of left and right returns to original shape, and left wall 51a and the right wall 51b of respective side 27a and embedded hole 51 abut.

And, now, at the bearing surface 42c that left surface 41c and the right flank 41d of sensor housing 41 are formed, the rear surface of the protuberance 52 of the left and right formed with left wall 51a and the right wall 51b at embedded hole 51 abuts, and the rear surface 28b of locking protrusion 28 of the rear surface 43b of the locking protrusion 43 formed at the upper surface 41e of sensor 41 and the arm 27 that is formed at left and right abuts with the front surface 50a of bracket 50.

Its result, the sensor housing 41 chimeric with the embedded hole 51 of bracket 50 is in following state: between the rear surface 28b of locking protrusion 28 and the rear surface 43b of locking protrusion 43 and bearing surface 42c, sandwich this bracket 50 on the thickness direction of bracket 50, thus this sensor housing 41 is locked to bracket 50.Like this, luminescence sensor 40 is fixed and held in bracket 50.

In addition, in this case, the rear surface 28b of the locking protrusion 28 and rear surface 43b of locking protrusion 43 is equal with the thickness of bracket 50 with the distance between bearing surface 42c, can reliably sandwich bracket 50 between which thus.

Like this, luminescence sensor 40 is installed in bracket 50.

Like this, in the installing mechanism of the second embodiment, arm 27 is formed at two sides 41c, 41d of the sensor housing 41 of luminescence sensor 40, and the bearing surface 42c that the rear surface 52a forming the protuberance 52 formed with two wall 51a, 51b of the embedded hole 51 at bracket 50 abuts, also forms locking protrusion 43 at the upper surface 41e of sensor housing 41.

And, when making this sensor housing 41 chimeric with the embedded hole 51 formed at bracket 50, be formed at sensor housing 41 left and right arm 47 locking protrusion 28 and between the locking protrusion 43 of upper surface 41e being formed at sensor housing 41 and the bearing surface 42c of two sides 41c, 41d being formed at sensor housing 41, the thickness direction of bracket 50 sandwiches and keeps this bracket 50.

Thus, even if relative to the bracket 50 be made up of the sheet metal that cannot form holding plate, also can fix and keep luminescence sensor 40.

Further, in order to three kinds of brackets that can be different from thickness are corresponding, luminescence sensor 40 defines different three bearing surfaces 42 (42a, 42b, 42c) of distance between front surface 41a at two sides 41c, 41d of sensor housing 41.

Thus, luminescence sensor 40 can be installed on three kinds of different brackets 50 of thickness.In addition, the protuberance 52 of mode to the embedded hole 51 of bracket 50 abutted with the bearing surface 42 (42a, 42b, 42c) corresponding with the thickness of bracket 50 positions.

And, luminescence sensor 40 is substantially identical with luminescence sensor 30 shape of the first embodiment, at two sides 41c, 41d, there is the arm 27 same with luminescence sensor 30, therefore can not only be installed on bracket 50, but also the conveying guiding piece 30 with holding plate 32 can be installed on.

Like this, luminescence sensor 40 just can be installed on the different bracket of thickness 50, conveying guiding piece 30 without the need to using the parts etc. installed in addition.Thus, the installing mechanism of monitoring sensor such as can also be selected according to actual installation condition.

According to above structure, the different bracket of thickness 50, conveying guiding piece 30 just can be installed on without the need to using the parts etc. installed in addition.Thereby, it is possible to suppression component number of packages, and at large luminescence sensor 40 can be used for various installing mechanism.Like this, can reduce costs further compared with the first embodiment.

[3. the 3rd embodiment]

Next the 3rd embodiment is described.In the 3rd embodiment, the shape of the arm of sensor housing is different from the first embodiment and the second embodiment.

In addition, because the structure etc. of the structure of the structure beyond the arm of sensor housing, automated teller machine 1, the conveying guiding piece 30 of sensor installation housing is identical with the first embodiment, therefore can with reference to the first embodiment.Thus, mainly the arm of sensor housing is described at this.

[arm of 3-1. sensor housing]

Figure 10 and Figure 11 (cut-open view) arm to sensor housing is utilized to be described.

In addition, even if in this case, except kind this point different of sensor, the luminescence sensor forming monitoring sensor is formed as substantially identical structure with photosensitive sensor.Therefore, mainly the arm of luminescence sensor is described at this.

As shown in Figure 10, at left surface 61a and the right flank 61b of the sensor housing 61 of luminescence sensor 60, respectively central authorities slightly on the lower surperficial 61c be partially formed recess 26, and be formed with arm 62 in the mode being embedded in this recess 26.

The arm 62 of left and right is formed as, from the rear end side of recess 26 tabular of the cross section that extends, side in roughly L-shaped forward, forming as one with gap the spaced apart of the end of the front of arm 62 and recess 26 with sensor housing 61 respectively.

And then the arm 62 of above-mentioned left and right has elasticity, thus respectively can make front end near and carry out elastic deformation away from the direction at the end of recess 26.

And then the respective front end of the arm 62 about this is formed with locking protrusion 63 outstanding laterally.The front surface 63a of this locking protrusion 63 is formed as taper surface.

In addition, in the 3rd embodiment, the side 62a of arm 62 is formed as towards front end and the taper surface tilted laterally, and arm 62 entirety is formed as more being close to the shape expanded more laterally front end.

In addition, if compared by the arm 27 of this arm 62 and the first embodiment, then, as shown in Figure 11 (cut-open view), the shape of the conical section 64 adding section triangle relative to the side 27a of arm 27 is formed as.

And, the rear surface 63b being formed at the locking protrusion 63 of the front end of arm 62 is formed as towards the side 62a of arm 62 and (from the front end of arm 62 towards the direction of rear end) taper surface of tilting upward, and entirety is formed as the roughly trapezoidal and wedge shape that front is sharp-pointed in cross section.

In addition, if compared by the locking protrusion 28 of this locking protrusion 63 and the first embodiment, as shown in Figure 11 (cut-open view), the shape adding the conical section 65 of section triangle at the rear surface 28b of locking protrusion 28 is formed as.

[3-2. action and effect]

When with said structure luminescence sensor 60 being installed on conveying guiding piece 30, the installation method same with the first embodiment is utilized to install.

Further, now, the rear surface 63b of the locking protrusion 63 of sensor housing 61 abuts with the locking surface 33a of the rear end side in the chimeric cave 33 of the holding plate 32 of left and right.

At this, not make the face that the rear surface 63b of the side 62a of the arm 62 of the left and right of the abutment portion as sensor housing 61 side and the locking protrusion 63 of left and right is formed as parallel relative to the medial surface 32a of holding plate 32 of left and right of the abutment portion as conveying guiding piece 30 side and the locking surface 33a in the chimeric cave 33 of the holding plate 32 of left and right, but make it be formed as taper surface, even if the size of sensor housing 61, holding plate 32 exists the deviation of manufacture view thus, the inclination of taper surface also can be utilized to absorb this deviation.

In fact, if the size of sensor housing 61, holding plate 32 exists the deviation of manufacture view, then sensor housing 61 offsets to the direction (fore-and-aft direction) absorbing this deviation because of the inclination of taper surface relative to the position of holding plate 32.

Its result, can make the abutment portion of sensor housing 61 side abut all the time with the abutment portion of conveying guiding piece 30 side, thus can prevent from producing gap between holding plate 32 and sensor housing 61.

And, when sensor housing 61 is greater than reference dimension or holding plate 32 is less than reference dimension, as shown in Figure 13 (cut-open view), can the arm 62 of left and right of elastic deformation respectively to the direction flexural deformation shown in arrow, can installment state be kept thus.

According to above structure, in the 3rd embodiment, on the basis of the effect same with the first embodiment, can also obtain and prevent between the holding plate 32 and sensor housing 61 of conveying guiding piece 30, producing gap thus preventing from rocking such effect.

[4. the 4th embodiment]

Next the 4th embodiment is described.In the 4th embodiment, the structure of the installing mechanism of monitoring sensor is different from the second embodiment.

[installing mechanism of 4-1. monitoring sensor]

In the 4th embodiment, monitoring sensor be installed on the bracket of sheet metal and utilize Figure 14 and Figure 15 to be described.

As shown in figure 14, luminescence sensor 70 has the sensor housing 71 of the roughly rectangular shape of lengthwise.This sensor housing 71 is formed by synthetic resin, is fixed with substrate 22 therein.And then at the connector 24 that this substrate 22 is provided with sensor element (i.e. light-emitting component) 23 and connects, the terminal part of connector 24 is exposed from the lower surface 71a of sensor housing 71.

And then also projecting above the front surface 71b of sensor housing 71 have columned light path portion 25, and it is consistent with the optical axis of the sensor element 23 in sensor 71 that this light path portion 25 is arranged to optical axis.

And then, at left surface 71c and the right flank 71d of sensor housing 71, be also formed with recess 26 in the local of central authorities surperficial 71a slightly on the lower respectively, and be formed with the arm 62 identical with the 3rd embodiment in the mode being embedded in this recess 26.

And then the respective front end of the arm 62 about this is formed with the locking protrusion 63 identical with the 3rd embodiment.

And then, at the left surface 71c of sensor housing 71 and right flank 71d and between arm 62 and the upper surface 71e of sensor housing 71, be formed with three bearing surfaces 42 (42a, 42b, 42c) identical with the second embodiment, these three bearing surfaces 42 are parallel from the front surface 71b of sensor housing 71 and different with distance between front surface 71b, and formed according to the order from small to large of the distance between front surface 71b from upper surface 71e side.

In addition, also three bearing surfaces 72 (72a, 72b, 72c) are formed at the left surface 71c of sensor housing 71 and right flank 71d between arm 62 and the lower surface 71a of sensor housing 71, these three bearing surfaces 72 are parallel from the front surface of sensor housing 71 and different with distance between front surface 71b, and formed according to the order from small to large of the distance between front surface 71b from lower surface 71a side in the mode of a part of left surface 71c and right flank 71d being excised.

Above-mentioned three bearing surfaces 72 (72a, 72b, 72c) also lay respectively at the position more more rearward than the rear surface 63b of locking protrusion 63.In addition, above-mentioned three bearing surfaces 72 (72a, 72b, 72c) will be described in detail below, when sensor installation, become the face abutted with the protuberance of bracket side, and distance separately and between the rear surface 63b of locking protrusion 63 is different, thus can sandwich between the rear surface 63b of locking protrusion 63 and the three kinds of brackets keeping thickness different.

In addition, at this, three of side more top than arm 62 bearing surfaces 42 (42a, 42b, 42c) are called upside bearing surface 42 (42a, 42b, 42c), downside bearing surface 72 (72a, 72b, 72c) will be called than arm 62 three bearing surfaces 72 (72a, 72b, 72c) more on the lower.

On the other hand, as shown in figure 15, bracket 80 is made up of the sheet metal of specific thickness, and is formed embedded hole 81 through for the rear surface 80b of front surface 80a and opposition side thereof.This embedded hole 81 with from the shape of the profile during sensor housing 71 of forward observation luminescence sensor 70 and size substantially identical, when sensor installation, this embedded hole 81 is chimeric with the sensor housing 71 of luminescence sensor 70.

Further, be formed with protuberance 82 at the left wall 81a of this embedded hole 81 and the respective central authorities position slightly by the top of right wall 81b, this protuberance 82 gives prominence to the inside in opposed mode and thickness is identical with bracket 80.And then.Also be formed with protuberance 83 at the left wall 81a of this embedded hole 81 and the respective central authorities position slightly on the lower of right wall 81b, this protuberance 83 gives prominence to the inside in opposed mode and thickness is identical with bracket 80.

In addition, at this, protuberance 82 of upside is called upside protuberance 82, the protuberance 83 of downside is called downside protuberance 83.

The upside protuberance 82 of left and right positions as follows: when sensor installation, in three upsides bearing surface 42 (42a, 42b, 42c) of two sides 71c, 71d being formed at sensor housing 71, the rear surface 82a of the upside protuberance 82 bearing surface 42c corresponding with the thickness of bracket 80 is abutted.

On the other hand, the downside protuberance 83 of left and right positions as follows: when sensor installation, in three downsides bearing surface 72 (72a, 72b, 72c) of two sides 71c, 71d being formed at sensor housing 71, the rear surface 83a of the downside protuberance 83 bearing surface 72c corresponding with the thickness of bracket 80 is abutted.

Further, the lower end side of embedded hole 81 and the shape opening accordingly of connector 24, thus when this embedded hole 81 is chimeric with the sensor housing 71 of luminescence sensor 70, the connector 24 exposed from the lower surface 71a of sensor 71 can not be stopped.

In addition, although eliminate explanation at this, in fact photosensitive sensor is arranged on the position opposed with luminescence sensor 70, is also provided with the bracket that the structure photosensitive sensor identical with bracket 80 is installed in this position.

[4-2. action and effect]

In above structure, when luminescence sensor 70 is installed on bracket 80, as shown in Figure 15 and Figure 16, under the state that the front surface 71b of the sensor housing 71 making luminescence sensor 70 is opposed with the rear surface 80b of bracket 80, from the 80b side, rear surface of bracket 80, this sensor housing 71 is inserted the embedded hole 81 of bracket 80.

Now, first the front surface 63a of the locking protrusion 63 in the left and right that the arm 62 of sensor housing 71 is formed abuts with the left wall 81a of the embedded hole 81 of bracket 80 and the edge of right wall 81b.

If be pressed into sensor housing 71 further from this state, the locking protrusion 63 that the front end of the arm 62 then in left and right is formed is pressed against the left wall 81a of embedded hole 81 and right wall 81b, the front end of the arm 62 of left and right is out of shape in the mode at the end of the recess 26 near left and right thus, and the bottom of sensor housing 71 is inserted into embedded hole 81.

If further press-in and make the locking protrusion 63 of the left and right of sensor housing 71 run through embedded hole 81, then respective front end is now made to be the arm 62 about recuperability acts on this away from the masterpiece at the end of the recess 26 of sensor housing 71.Its result, the arm 27 of left and right returns to original shape.

Now, the rear surface 63b of respective locking protrusion 63 of the arm of left and right abuts with the front surface 80a of bracket 80.

And, now, at the upside bearing surface 42c that left surface 71c and the right flank 71d of sensor housing 71 are formed, the rear surface 82a of the upside protuberance 82 of the left and right formed with left wall 81a and the right wall 81b at embedded hole 81 abuts, and abuts at the rear surface 83a of the downside protuberance 83 of the left and right that the downside bearing surface 72c that left surface 71c and the right flank 71d of sensor housing 71 are formed is formed with left wall 81a and the right wall 81b at embedded hole 81.

Its result, the sensor housing 71 chimeric with the embedded hole 81 of bracket 80 is in following state: between the rear surface 63b and upside bearing surface 42c and downside bearing surface 72c of locking protrusion 63, sandwich this bracket 80 on the thickness direction of bracket 80, thus this sensor housing 71 is locked to bracket 80.Like this, sensor housing 71 is fixed and held in bracket 80.

Like this, luminescence sensor 70 is installed in bracket 80.

Like this, in the installing mechanism of the 4th embodiment, arm 62 is formed at two sides 71c, 71d of the sensor housing 71 of luminescence sensor 70, and form the bearing surface 42c abutted with the upside protuberance 82 that the embedded hole 81 at bracket 80 is formed in the upside of arm 62, and then form the downside bearing surface 72c abutted with the downside protuberance 83 of the embedded hole 81 being formed at bracket 80 in the downside of arm 62.

And, when making this sensor housing 71 chimeric with the embedded hole 81 of bracket 80, be formed at sensor housing 71 left and right arm 62 locking protrusion 63 and be formed at left and right arm 62 upside upside bearing surface 42c and be formed at downside downside bearing surface 72c between, sandwich in a thickness direction keep bracket 80.

Thus, even if relative to the bracket 80 be made up of sheet metal, also can fix and keep luminescence sensor 70.

But, in the above-described 3rd embodiment, even if make to be formed as taper surface at the side 62a of arm 62, the rear surface 63b of locking protrusion 63 that formed with the front end of arm 62, thus make holding plate 32, there is the deviation of manufacture view in the size of sensor housing 61, also can prevent from producing gap between holding plate 32 and sensor housing 61.

At this, even if such as the sensor housing 41 of the second embodiment, if the rear surface 28b of the locking protrusion 28 of the side 27a making arm 27 and the front end being formed at arm 27 is formed as taper surface, also can prevent from producing gap between bracket 50 and sensor housing 41.

But, in this case, if the size of bracket 50, sensor housing 41 exists the deviation of manufacture view, then can make sensor housing 41 because of taper surface relative to the position of bracket 50 to direction (fore-and-aft direction) skew for this deviation being absorbed.In this case, for forwards pushing the masterpiece of arm 27 part of left and right for sensor housing 41.

Now, the part of the more top side of ratio arm 27 of sensor housing 41, bracket 50 is pressed against because bearing surface 42c abuts with the rear surface 52a of the protuberance 52 of bracket 50, owing to not there is than arm 41 part more on the lower the part that abuts with bracket 50 and not being pressed against bracket 50, be therefore pushed to front.Its result, sensor housing 41 is such as tilting as shown in Figure 17.

Like this, if sensor housing 41 tilts, then optical axis can misplace between luminescence sensor 40 and photosensitive sensor, thus the supervision precision of monitoring sensor likely can be made to reduce.

Therefore, in the 4th embodiment, the side 62a making arm 62 is formed as taper surface with the rear surface 63b of the locking protrusion 63 of the front end being formed at arm 62, and not only the upside of the arm 62 of sensor housing 71 and also arrange in downside downside bearing surface 72 (72a, 72b, 72c), the upside of not only arm 62 thus, and downside is also pressed against bracket 80.

Thereby, it is possible to prevent sensor housing 71 from tilting, thus can prevent optical axis from misplacing between luminescence sensor 70 and photosensitive sensor.In other words, the part of the inclination not considering sensor housing 71 can be said, the adjustment of the optical axis between luminescence sensor 70 and photosensitive sensor can be made to become easy.

According to above structure, in the 4th embodiment, can prevent from producing gap between bracket 80 and sensor housing 71, and the inclination of sensor housing 71 can be prevented, thus the dislocation of the optical axis between luminescence sensor 70 and photosensitive sensor can be prevented.

[5. the 5th embodiment]

Next the 5th embodiment is described.In the 5th embodiment, the structure of the installing mechanism of monitoring sensor is different from the 4th embodiment.

[installing mechanism of 5-1. monitoring sensor]

In the 5th embodiment, monitoring sensor be installed on the bracket of sheet metal and utilize Figure 18 to Figure 20 to be described.

As shown in figure 18, luminescence sensor 200 has the sensor housing 201 of the roughly rectangular shape of lengthwise.This sensor housing 201 is formed by synthetic resin, is fixed with substrate 22 therein.And then at the connector 24 that this substrate 22 is provided with sensor element (i.e. light-emitting component) 23 and connects, the terminal part of connector 24 is exposed from the lower surface 71a of sensor housing 201.

And then also projecting above the front surface 201a of sensor housing 201 have columned light path portion 25, and it is consistent with the optical axis of the sensor element 23 in sensor 201 that this light path portion 25 is arranged to optical axis.

In above structure, when luminescence sensor 300 is installed on thinner bracket 310, as shown in Figure 24 and Figure 26, make the front surface 301a of the sensor housing 301 of luminescence sensor 300 opposed with the rear surface 310b of bracket 310, and make the position consistency of the protuberance 314 of the position of the locating slot 304 being arranged at the left surface 301b of sensor housing 301 and the left and right of right flank 301c and the left and right of bracket 310, be pressed into sensor housing 301 from the embedded hole 311 of the rear surface 310b side direction bracket 310 of bracket 310 in this condition.

Now, at the front surface 63a of the locking protrusion 63 of the left and right that the arm 62 of sensor housing 301 is formed, first abut with the left wall 311a of the embedded hole 311 of bracket 310 and the edge of right wall 311b.

If be pressed into sensor housing 301 further from this state, the locking protrusion 63 that the front end of the arm 62 then in left and right is formed is pressed against the left wall 311a of embedded hole 311 and right wall 311b, the front end of the arm 62 of left and right is out of shape in the mode at the end of the recess 26 near left and right thus, and sensor housing 301 is inserted into embedded hole 311.

If further press-in and make the locking protrusion 63 of the left and right of sensor housing 301 run through embedded hole 311, then respective front end is now made to be the arm 62 about recuperability acts on this away from the masterpiece at the end of the recess 26 of sensor housing 301.Its result, the arm 62 of left and right returns to original shape.

Now, the rear surface 63b of respective locking protrusion 63 of the arm 62 of left and right abuts with the front surface 310a of bracket 310.

And, now, the upside bearing surface 302 formed at left surface 301b and the right flank 301c of sensor housing 301 abuts with the rear surface 312a on the wall top 312 of the left and right of embedded hole 311, and abuts with the rear surface 313a of the wall bottom 313 of the left and right of embedded hole 311 at the downside bearing surface 203 that left surface 301b and the right flank 301c of sensor housing 301 are formed.

Its result, the sensor housing 301 chimeric with the embedded hole 311 of bracket 310 is in following state: between the rear surface 63b of locking protrusion 63 and upside bearing surface 302a and downside bearing surface 203, sandwich this bracket 310 on the thickness direction of bracket 310, thus this sensor housing 301 is locked to bracket 310.

And then now, the protuberance 314 of the left and right of bracket 310 is chimeric with the locating slot 304 of the left and right of sensor housing 301.

At this, as mentioned above, to be formed as the length of above-below direction substantially equal with the length of the above-below direction of the protuberance 314 of bracket 310 for the locating slot 304 of sensor housing 301.

Therefore, if the protuberance 314 of bracket 310 is chimeric with this locating slot 304, then the state that sensor housing 310 is fixed relative to the position on the above-below direction of bracket 310 is formed as.

Like this, sensor housing 301 is fixed and held in bracket 310.

Thus, luminescence sensor 300 is installed in bracket 310.

On the other hand, when luminescence sensor 300 is installed on thicker bracket 320, as shown in Figure 25 and Figure 27, make the front surface 301a of the sensor housing 301 of luminescence sensor 300 opposed with the rear surface 320b of bracket 320, and make the position consistency of the protuberance 322 of the position of the locating slot 304 being arranged at the left surface 301b of sensor housing 301 and the left and right of right flank 301c and the left and right of bracket 320, the embedded hole 321 thus from the 320b side, rear surface of bracket 320 towards bracket 320 is pressed into sensor housing 301.

Now, first the front surface 63a being formed at the locking protrusion 63 of the left and right of the arm 62 of sensor housing 301 abuts with the left wall 321a of the embedded hole 321 of bracket 320 and the edge of right wall 321b.

If be pressed into sensor housing 301 further from this state, the locking protrusion 63 being then formed at the front end of the arm 62 of left and right presses on the left wall 321a of embedded hole 321 and right wall 321b, the front end of the arm 62 of left and right is out of shape in the mode at the end of the recess 26 near left and right thus, thus sensor housing 301 is inserted into embedded hole 321.

If be pressed into further and make the locking protrusion 63 of the left and right of sensor housing 301 run through embedded hole 321, then now respective front end is the arm 62 that recuperability acts on left and right for the masterpiece at the end of the recess 26 away from sensor housing 301.Its result, the arm 62 of left and right returns to original shape.

Now, the rear surface 63b of respective locking protrusion 63 of the arm 62 of left and right abuts with the front surface 320a of bracket 320.

And, now, at the front surface 303a of the upside locking protrusion 303 that left surface 301b and the right flank 301c of sensor housing 301 are formed, abut with the rear surface 323a of the protuberance 323 of the left and right of embedded hole 321, and abut with the rear surface 324a of the wall bottom 324 of the left and right of embedded hole 321 at the front surface 204a of locking protrusion 204 that left surface 301b and the right flank 301c of sensor housing 301 are formed.

Its result, between the rear surface 63b of locking protrusion 63 and the front surface 204a of the front surface 303a of upside locking protrusion 303 and downside locking protrusion 204, the thickness direction of bracket 320 sandwiches bracket 320, thus the sensor housing 301 chimeric with the embedded hole 321 of bracket 320 becomes the state being locked to bracket 320.

And then now, the protuberance 322 of the left and right of bracket 320 is chimeric with the locating slot 304 of the left and right of sensor housing 301.

At this, the protuberance 322 of thicker bracket 320 is equal with the length that the protuberance 314 of thinner bracket 310 is formed as above-below direction.

Therefore, the length of the above-below direction of locating slot 304 is substantially equal with the length of the above-below direction of the protuberance 322 of bracket 320.

Therefore, if the protuberance 322 of bracket 320 is chimeric with this locating slot 304, then the state that sensor housing 301 is fixed relative to the position on the above-below direction of bracket 320 is formed as.

In addition, the position of sensor housing 301 relative to the above-below direction of bracket 310 and 320 positions by the locating slot 304 of sensor housing 301, and is not positioned the position of fore-and-aft direction (thickness direction).Therefore, when sensor installation, locating slot 304 is positioned at the position more more rearward than the front surface 303a of upside the locking protrusion 303 and front surface 204a of downside locking protrusion 204, does not all abut with bracket 310 and 320 to make rear surface 304a.Like this, sensor housing 301 is fixed and held in bracket 320.

Thus, luminescence sensor 300 is installed in bracket 320.

Thus, in the 6th embodiment, luminescence sensor 200 installed by two kinds of brackets 310,320 that can be different relative to thickness.

Further, in the 6th embodiment, identical with above-mentioned 5th embodiment, can prevent sensor housing 301 from tilting because having the arm 62 of cone-shaped.

But, in the 5th embodiment, such as when sensor housing 201 being installed on thinner bracket 210, upper surface 201d abuts with the upper wall surface 211c of the embedded hole 211 of bracket 210, and be positioned at the lower surface, front side 205 of side more forward than the downside bearing surface 203 of left surface 201b and right flank 201c, abut with the lower surface 215 of lower end of left wall 211a and 211b of the embedded hole 211 being positioned at bracket 210, be fixed relative to the position of the above-below direction of bracket 210 thus.

On the other hand, when sensor housing 201 being installed on thicker bracket 220, upper surface 201d abuts with the upper wall surface 221c of the embedded hole 221 of bracket 220, and be positioned at the rear side lower surface 206 of downside bearing surface 203 side more rearward than left surface 201b and right flank 201c, abut with the lower surface 223 of lower end of left wall 221a and 221b of the embedded hole 221 being positioned at bracket 220, be fixed relative to the position of the above-below direction of bracket 220 thus.

At this, for luminescence sensor 200, the size of the area can guaranteed as lower surface, front side 205 and rear side lower surface 206 changes according to the size of the size of sensor housing 201 and connector 24.

In fact, the transverse width of sensor housing 201 and the transverse width of connector 24 more close, the thickness of more necessary thinning sensor housing 201, and reduce the area that can guarantee as lower surface, front side 205 and rear side lower surface 206.

Like this, if the area can guaranteed as lower surface, front side 205 and rear side lower surface 206 reduces, then such as when sensor housing 201 is installed on thinner bracket 210, be arranged at the lower surface, front side 205 of two sides 201b, 201c of sensor housing 201, the area (area shown in the a1 × b1 shown in Figure 21 (C)) of part that contacts with the lower surface 215 of two wall 211a, 211b of the embedded hole 211 being arranged at bracket 210 reduces.

Its result, likely causes abutting thus departing from or sensor housing 201 rocks of the lower surface, front side 205 of sensor housing 201 and the lower surface 215 of bracket 210 because vibration waits.

And, such as when sensor housing 201 is installed on thicker bracket 220, be arranged at the rear side lower surface 206 of two sides 201b, 201c of sensor housing 201, the area (area shown in the a2 × b2 shown in Figure 21 (C)) of part that contacts with the lower surface 215 of two wall 221a, 221b of the embedded hole 221 being arranged at bracket 220 also reduces.

In this case, abutting thus departing from or sensor housing 201 rocks of the rear side lower surface 206 of sensor housing 201 and the lower surface 223 of bracket 220 is also likely caused because vibration waits.

In fact, such as, the thickness of sensor 201 is set to 0.7mm, the thickness of thinner bracket 210 is set to 1.0mm, the thickness of thicker bracket 220 is set to 1.6mm.

At this, when sensor housing 201 is installed on thinner bracket 210, the area (a1 × b1) of the part that the lower surface, front side 205 of sensor housing 201 contacts with the lower surface 215 of bracket 210 is 0.7 × 1.0mm ².

On the other hand, when sensor housing 201 is installed on thicker bracket 220, the area (a2 × b2) of the part that the lower surface, front side 206 of sensor housing 201 contacts with the lower surface 223 of bracket 220 is 0.7 × 0.6mm ².

Under these circumstances, when sensor housing 201 is installed on thicker bracket 220, it is higher that sensor housing 201 departs from the possibility that bracket 220 or sensor housing 201 rock.

Therefore, in the 6th embodiment, at two sides 301b, 301c of sensor housing 301, locating slot 304 is set, make the protuberance 314 of bracket 310, the protuberance 322 of bracket 320 chimeric with this locating slot 304, sensor housing 301 is fixed relative to the position of the above-below direction of bracket 310, bracket 320 thus.

Thus, and do not rely on the size of lower surface 205, front side, rear side lower surface 206, just can prevent sensor housing 301 from coming off relative to bracket 310, bracket 320 or rocking.

And, above the position that the accommodation space being arranged at the connector 24 arranged with the lower inner at arm 62 due to locating slot 304 is not directly interfered that is arm 62, even if therefore such as when the area can guaranteed as lower surface, front side 205, rear side lower surface 206 is less, also can keep guaranteeing enough degree of depth to make the protuberance 322 of the protuberance 314 of sensor housing 301 and bracket 310, bracket 320 chimeric and being fixed sensor housing 301.

Like this, in the sensor housing 301 of the 6th embodiment, compared with the first to the 5th embodiment, reliably sensor housing 301 can be fixed on bracket 310 and 320 further, its result can reliably prevent optical axis from misplacing between luminescence sensor 300 and photosensitive sensor further.

According to above structure, in the 6th embodiment, on the basis of the effect identical with the 5th embodiment, the effect reliably sensor housing 301 being fixedly held in bracket 310 and 320 further can also be obtained.
