In regional A1, the A2 of medial region A1, zone line A2 and exterior lateral area A3, A3, configure 1 or more than or equal to the light source 30 of 2.As the kind of light source 30, any one that can be Fig. 8 to spot light 30P shown in Figure 11, line source 30L, Figure 13 shown in Figure 12 and the area source 30PL shown in Figure 14.For example, in the situation that selected element light source 30P or line source 30L as light source 30,, need only regional A1, A2, A3 configuration light source 30 separately to shown in Figure 12 as Fig. 8.In addition, in the situation that select area source 30PL as light source 30, as Figure 13 and shown in Figure 14, as long as the area source 30PL of the circle that will increase gradually according to the order of medial region A1, zone line A2 and exterior lateral area A3, from the below successively to be configured in area source 30PL exterior lateral area A3, to be configured in area source 30PL in zone line A2, to be configured in the order of the area source PL in medial region A3,, get final product thereby these light sources 30 are configured in respectively in regional A1, A2, A3 these area sources 30PL overlay configuration with concentric circles.As the light source 30 of present embodiment, as shown in Figure 8, adopt the spot light 30P such as LED (light emitting diode), a plurality of spot light 30P are configured in the whole zone of regional A1, A2, A3 in gapless mode.
A plurality of speculums 25,26,27, as shown in Figure 7, respectively with suitable inclination angle configuration in position, so that from medial region A1, the zone line A2 of lighting apparatus 28 and regional A1, the A2 of exterior lateral area A3 irradiation, the light of A3, reflection becomes front projection light L1, positive oblique light L3 or sidelight L2.A plurality of speculums 25,26,27 of present embodiment are made of half-reflecting mirror 25, bottom speculum 26 and top speculum 27 as previously mentioned.
Half-reflecting mirror 25 between face battle array camera 20, is in the position relative with lighting apparatus 28 at button maintaining part 6a.Here, so-called half-reflecting mirror 25 is that the light in provision wavelengths zone is separated with transmissivity with reflectivity arbitrarily, and adjusts the speculum of its light quantity, as its typical example, can enumerate the half-reflecting mirror of metallic mirror type or the half-reflecting mirror of dielectric reflection-type.The half-reflecting mirror of metallic reflection type, although light loss is large, the variation of incidence angle or polarisation makes transmissivity and reflectance varies hardly.On the other hand, although the half-reflecting mirror of dielectric reflection-type does not almost have light loss, because of the variation of incidence angle or polarisation, transmissivity and reflectance varies are very large.
As the half-reflecting mirror 25 of present embodiment, as Figure 6 and Figure 7, use the half-reflecting mirror 25 of the dielectric reflection-type that forms rectangle.And, half-reflecting mirror 25 tilted configuration, so that the light of 28 the medial region A1 incident reflection and become front projection light L1 from the field of illumination, and, make light from button B incident (at the light of the surface reflection of button B) towards face battle array camera 20 and transmissions.In the present embodiment because the allocation position quadrature of the allocation position of face battle array camera 20 and lighting apparatus 28, so that half-reflecting mirror 25 from lighting apparatus 28 over against tilt 45 degree left and right and configuring of direction.
The inclination angle [theta] 2 of bottom speculum 26 is preferably set to 40 degree～50 degree as shown in figure 15.Inclination angle [theta] 2 for this bottom speculum 26, as shown in Figure 7, setting the reflecting surface 26a of section's speculum 26 inclination angle [theta] 2 when parallel with the vis-a-vis direction D of button maintaining part 6a is 0 degree, and the angle when the reflecting surface 26a that sets section's speculum 26 tilts to the direction relative with half-reflecting mirror 25 is positive angle.
This framework 33 has inside cylindrical framework 35 and outside cylindrical framework 34.By form respectively thread 36 on the medial surface 34a of the lateral surface 35a of inside cylindrical framework 35 and outside cylindrical framework 34, inside cylindrical framework 35 is screwed to the inboard of inside cylindrical framework 34, thereby inside cylindrical framework 35 and outside cylindrical framework 34 are configured with concentric circles.Configuration top speculum 27 on the medial surface 35b of this inside cylindrical framework 35, by making inside cylindrical framework 35 rotations that are screwed on outside cylindrical framework 34 inboards, freely adjust the height of inside cylindrical framework 35 on the vis-a-vis direction D of button maintaining part 6a.In other words, top speculum 27 has the height regulating mechanism of adjusting height on the vis-a-vis direction D of button maintaining part 6a.
In addition, the inclination angle [theta] 3 of top speculum 27 as shown in figure 15, is preferably set to 5.0 degree～22.5 degree.Inclination angle [theta] 3 for this top speculum 27, if the inclination angle [theta] 3 when the reflecting surface 27a of top speculum 27 is parallel with the vis-a-vis direction D of button maintaining part 6a is 0 degree, the angle when the reflecting surface 27a that establishes top speculum 27 tilts to the direction relative with half-reflecting mirror 25 is positive angle.
In addition, for top speculum 27 and bottom speculum 26, might not form shown in Figure 15 circular.For example, as shown in figure 16, also can with circular speculum burst, form reflecting optics 26P (27P), be configured to this reflecting optics 26P (27P) circular or more than or equal to the polygon ring-type on six limits, thereby form top speculum 27 and bottom speculum 26.In addition, for the shape of this reflecting optics 26P (27P), also can not be bent to form and become rectangular flat shape.In addition, as Figure 11 and shown in Figure 12, if the shape of the zone line A2 of lighting apparatus 28 or exterior lateral area A3, except circular or more than or equal to the regulation shape the polygon ring-type on six limits, shape or the configuration of top speculum 27 or bottom speculum 26, preferably corresponding with the regulation shape (for example hexagon) of zone line A2 or exterior lateral area A3 and form.
Below, the effect of button automatic supplier 10 and the button differentiating device 1 of present embodiment is described.Below, describe according to the motion flow of Figure 17.
If drop into a plurality of button Bs at Fig. 1 to the confession orifice ring 2a of button supply unit 2 shown in Figure 3, and make this confession orifice ring 2a begin vibration, a plurality of button Bs towards the supply port 2 of button supply unit 2, advance respectively while pass through button path 2b.If button B arrives the supply port 2c of button supply unit 2, this button B falls from supply port 2c, thereby button B is supplied to the button maintaining part 6a (with reference to the S1 of Figure 17) of the 1st rotor plate 6 under supply port 2c.
As extremely shown in Figure 4 in Fig. 2, if the 1st rotor plate 6 is rotated counterclockwise 90 degree, this button maintaining part 6a moves to the below of face battle array camera 20 from the below of supply port 2c, the mobile message of the 1st rotor plate 6 is passed to illumination control circuit (brightness adjustment unit) 22 from shown in Figure 6 center-control section 40 via CPU 39.And, illumination control circuit 22 is in order to obtain being suitable for the shape of button B and the contrast of pattern, according to the lighting condition that is stored in ROM 38, set respectively for front projection light L1, positive oblique light L3 and sidelight L2, that is, in the present embodiment regional A1, the A2 of lighting apparatus 28, the brightness of spot light 30P in A3 are set in respectively (with reference to the S2 of Figure 17) between 0～100%.
As shown in Figure 7, if contrast settings is completed, illumination unit 21 uses light source 30 to begin illumination, for the button B that is positioned at face battle array camera 20 belows, supplies with front projection light L1, positive oblique light L3 and sidelight L2 (with reference to the S3 of Fig. 7).Be supplied to the light of button B at the surface reflection of button B, see through half-reflecting mirror 25 and incide face battle array camera 20.That is to say, front projection light L1, positive oblique light L3 and sidelight L2 that face battle array camera 20 reflects by reception take button B (with reference to the S4 of Figure 17).
For utilizing which kind of method that front projection light L1, positive oblique light L3 and sidelight L2 are supplied to button B, consider the whole bag of tricks here.For example, be not only this illumination unit 21 by lighting apparatus 28 and a plurality of speculum 25,26,27 are combined of present embodiment and carry out the supply of light, as shown in figure 18, also can not use a plurality of speculums 25,26,27 of present embodiment, and with vis-a-vis direction D, front incline direction and the side of light source 30 decentralized configuration at button B.In addition, as shown in figure 19, in the situation that use a plurality of speculums, also can light source 30 not concentrated on a position and on all directions decentralized configuration, a plurality of speculums are set as shape, configuration and the inclination angle different from half-reflecting mirror 25, bottom speculum 26 and the top speculum 27 of present embodiment shown in Figure 7.
In any one illumination unit 21, can be by shine front projection light L1, positive oblique light L3 and sidelight L2 to button B, and by illumination control circuit 22, these light are carried out suitable brightness adjustment, and strengthen the contrast of the image of captured button B.And, because can by strengthening the contrast of image, improve the visuality of the image of button B, so easily capture the feature that occurs on the positive Bs of captured button B.
For example, as shown in figure 20, the surperficial back side at button B does not have relief pattern, its surperficial back side is all smooth, and the difference at the surperficial back side of button B only is that whether the periphery at the effects on surface back side carries out in the situation of chamfer machining, reduce the brightness of front projection light L1 and positive oblique light L3, improve simultaneously the brightness adjustment of the brightness of sidelight L2.Thus, as shown in figure 20, with the face that does not carry out the periphery chamfer machining of button B as surperficial Bx, and should surface Bx as positive Bs and button B is configured in situation on button maintaining part 6a, as shown in figure 21, the light and shade of the positive Bs of button B clearly shows as the boundary take its periphery.On the other hand, as shown in figure 22, in the situation that take the back surface B y of button B as positive Bs, because the periphery of the positive Bs of button B has carried out chamfer machining, so as shown in figure 23, positive Bs at button B does not clearly show light and shade, but from bright darker inboard, lateral, level occurs on button B.
In addition, as shown in figure 24, in the situation that the periphery of the surperficial Bx of button B is with cylindric protrusion, the brightness adjustment of the brightness by improving the positive oblique light L3 on the surperficial Bx that shines button B, and make the surperficial Bx of button B occur positive oblique light L3 irradiation less than part.Thus, as shown in figure 25, the part that the periphery of the surperficial Bx of button B protrudes becomes clear because of the light and shade of light, circular contour occurs clearly in the inboard of the profile of the periphery of button B.On the other hand, as shown in figure 26, if the back surface B y of button B is smooth circle, can not produce on its back surface B y positive oblique light L3 irradiation less than part.Therefore, as shown in figure 27, although the profile of the periphery of button B occurs, circular contour does not appear in side within it.
In addition, the button B of Figure 24～Figure 27 is that the periphery at its surperficial Bx has protuberance cylindraceous, but in the situation that its surperficial Bx forms relief pattern, also can by the brightness adjustment of positive oblique light L3, catch reliably the feature at the surperficial back side of button B, i.e. relief pattern.Like this, as Figure 28 and shown in Figure 29, for the damaged Bc of button B, also can by same brightness regulation, catch reliably its damaged Bs as characteristic point.
Certainly, in the situation that shooting has the button B of a plurality of aforementioned features, also can by suitably adjusting brightness of illumination separately, clearly identify the feature of button B.That is to say, match and suitably adjust with shape or the pattern at the surperficial back side of button B by light L1, the L2 that makes three directions, the brightness of L3, the surperficial back side that can obtain button B has the image of the button B of clear and definite feature, therefore, when the image of button B and discrimination standard image are compared, can easily carry out the surperficial back side of button B and differentiate.
Here, in order to shine aforementioned front projection light L1, positive oblique light L3 and sidelight L2, the illumination unit 21 of present embodiment as Figure 6 and Figure 7, is formed by lighting apparatus 28 and a plurality of speculum 25,26,27.Fig. 6 and Fig. 7 and Figure 18 are compared as can be known, by use a plurality of speculums 25,26,27 in lighting unit 21, can significantly improve the configuration free degree of lighting apparatus 28.
In addition, by Fig. 6 and Fig. 7 and Figure 19 are compared as can be known, the lighting unit 21 of present embodiment, a plurality of light sources 30 are configured on the light source configuration plane 29a of 1 lighting apparatus 28, a plurality of speculums 25,26,27 that use is made of half-reflecting mirror 25, bottom speculum 26 and top speculum 27 will disperse to three directions to the light of a direction irradiation.Therefore, and a plurality of light sources 30 are compared in all directions decentralized configuration, can be reduced the configuration space of illumination unit 21.For the button differentiating device 1 of present embodiment, as Figure 6 and Figure 7, can be by reducing the configuration space of illumination unit 21, thus reduce the configuration space of button differentiating device 1.
But, if a plurality of light sources 30 are configured on same light source configuration plane 29a thick and fast, can mutually interfere from adjacent a plurality of light sources 30 irradiation light, even respectively front projection light L1, positive oblique light L3 and sidelight L2 are carried out brightness adjustment, also be difficult to carry out accurate adjustment.Therefore, in the lighting apparatus 28 of present embodiment, as shown in Figure 8, on the boundary line of medial region A1, the zone line A2 of light source configuration plane 29 and exterior lateral area A3, shading wall 31a, 31b, 31c are set respectively.Thus, can prevent that namely front projection light L1, positive oblique light L3 and sidelight L2 interfere mutually from the light of this regional A1, A2, A3 irradiation.In addition, even a plurality of light sources 30 are configured on same light source configuration plane 29a thick and fast, also can critically control the brightness of front projection light L1, positive oblique light L3 and sidelight L2.
In addition, dispose respectively medial region A1, zone line A2 and the exterior lateral area A3 of the light source 30 of these front projection light of irradiation L1, positive oblique light L3 and sidelight L2, the shape of observing from the positive Bs of button B, if not circular or with its figure that approaches, can't equably these light integrally be shone positive Bs and the side of button B.Therefore, in the lighting apparatus 28 of present embodiment, make medial region A1, zone line A2 and exterior lateral area A3 form circle or more than or equal to the polygon on six limits or annular or more than or equal to the polygon annular on six limits, and be configured as circular concentric or polygon with one heart.Thus, can integrally shine positive Bs and the side of button B.
Certainly, even being shaped as of regional A1, the A2 of lighting apparatus 28, A3 is circular or circular, if and the shape of top speculum 27 and bottom speculum 26 or configuration shape are not circular, only have from the part of the light of lighting apparatus 28 irradiation and incide on top speculum 27 and bottom speculum 26.Therefore, top speculum 27 and bottom speculum 26, as Fig. 6 and Fig. 7 and Figure 15 and shown in Figure 16, form annular or more than or equal to the polygon ring-type on six limits, be preferably and regional A1, A2, shape that the A3 shape is identical.In view of most of button Bs are circular, regional A1, A2, A3 and top speculum 27 by making lighting apparatus 28 and bottom speculum 26 become circle or annular or more than or equal to the polygon ring-type on six limits, can make front projection light L1, positive oblique light L3 and sidelight L2 integrally shine positive Bs and the side of button B.
In addition, for bottom speculum 26 and top speculum 27, its inclination angle [theta] 2, θ 3 are also very important.As shown in Figure 7, inclination angle [theta] 2 at bottom speculum 26 is set to aforementioned 40 degree～50 degree, particularly in the situation of 45 degree, because can make from the zone line A2 outgoing of lighting apparatus 28 and by half-reflecting mirror 25 reflections with the light of the vis-a-vis direction D parallel radiation of button B, namely with the light of front projection light L1 parallel radiation, become sidelight L2 with front projection light L1 quadrature, shine the side of button B, so can not make the light of the regional A2 irradiation from the centre at random, roughly all light all can be focused on the side of button B.
In the situation that the inclination angle [theta] 3 of above-mentioned speculum 27 is set as aforesaid 5.0 degree～22.5, can with penetrate from the exterior lateral area A3 of lighting apparatus 28 and by half-reflecting mirror 25 reflections with the light of the vis-a-vis direction D parallel radiation of button B, namely with the light of front projection light L1 parallel radiation, be transformed to positive oblique light L3.In addition, if the inclination angle [theta] 3 of top speculum 27 is 0～5.0 degree, even reflected by top speculum 27 light that also only becomes with front projection light L1 almost parallel because of the light with front projection light L1 almost parallel, so as positive oblique light L3, almost useless.In addition, as shown in figure 30, if the inclination angle [theta] 3 of top speculum 27 is more than or equal to 22.5 degree, because the inclination angle of positive oblique light L3 becomes 2 times of inclination angle [theta] 3 of top speculum 27 namely more than or equal to 45 degree, so on the positive Bs that is difficult to make positive oblique light L3 shine button B.
In addition, for top speculum 27, be not inclination angle [theta] 3, the configuration height on the vis-a-vis direction D at button maintaining part 6a is also very important.This is because as shown in figure 31, the point of irradiation of positive oblique light L3 can be along with the reduction of the configuration height of top speculum 27 from the mediad of the positive Bs of button B side shifting outside it.That is to say, by on top speculum 27, height regulating mechanism being set, because the irradiation area that can make positive oblique light L3 with respect to the central authorities of the positive Bs of button B and to the inside direction or lateral direction moves, so can when the large minor change of button B, suitably change the irradiation area of positive oblique light L3.
Specifically, as Figure 6 and Figure 7, utilize the inside cylindrical framework 35 of the framework 33 that supports top speculum 27, adjust the height of top speculum 27.Framework 33 is screwed togather and is formed by inside cylindrical framework 35 and outside cylindrical framework 34, and its inside cylindrical framework 35 can move freely on its short transverse.Therefore, can move on short transverse by making inside cylindrical framework 35, thereby top speculum 27 is adjusted in its short transverse together.In addition, by being adjusted the height of inside cylindrical framework 35 by the rotation of inside cylindrical framework 35, because can be continuously and adjust minutely its height, so can accurately set the irradiation area of positive oblique light L3.In addition, if on framework 35 and framework 34, scale is set suitably, can be adjusted into the setting that the same button is had repeatability.
As shown in figure 17, supply with front projection light L1, positive oblique light L3 and sidelight L2 (with reference to the S3 of Figure 17) at the illumination unit 21 that is consisted of by lighting apparatus 28 and a plurality of speculum 25,26,27 to button B, after the shooting of strengthening contrast and carry out this button B (with reference to the S4 of Figure 17), the lighting apparatus 28 of illumination unit 21 is stopped (with reference to the S5 of Figure 17).
After the illumination of lighting unit 21 stops (with reference to the S5 of Figure 17), the CPU 39 of judgement unit 23, be stored in the image of the button B in the RAM 37 of judgement unit 23 after being taken by face battle array camera 20, compare (with reference to the S6 of Figure 17) with discrimination standard image in the ROM 38 that is stored in judgement unit 23.Then, CPU 39 is these images and judge whether the surperficial back side of button B is the direction of regulation relatively, and on button B whether jagged or break etc. damaged (with reference to the S7 of Figure 17).
Here, as Figure 20, Figure 22, Figure 24, Figure 26 and shown in Figure 28, because illumination unit 21 make from the light of three directions (front projection light L1, positive oblique light L3 and sidelight L2) with take suitable brightness and be supplied to the button B of being taken by face battle array camera 20, so as Figure 21, Figure 23, Figure 25, Figure 27 and shown in Figure 29, the image of button B is had be suitable for carrying out the surperficial back side of button B and the contrast of damaged differentiation most.That is to say, utilize the illumination unit 21 of present embodiment, can compared with prior art, significantly improve the visuality of the image of the button B of being taken by face battle array camera 20.Therefore, judgement unit 23 can be accurate and the surperficial back side of the button B that forms a prompt judgement whether be the direction of expectation, and on button B whether jagged or break etc. damaged (with reference to the S7 of Figure 17).And, obtain the conclusion (with reference to the S8 of Figure 17) of the surperficial back side of this button B and damage condition normal (the surperficial back side of button B is the state of N/D on the direction of expectation and button B) or abnormal (the surperficial back side of button B is not on the direction of expectation or button B, damaged state to be arranged).
If the surperficial back side and the damage condition of button B are normal, the button B after differentiating is delivered to the sewing machine base 50a of section (with reference to the S9 of Figure 17) of button sewing machine 50.In the button supply unit 3 of present embodiment, as extremely shown in Figure 4 in Fig. 2, button B after shooting and differentiation, be rotated counterclockwise 90 positions of spending because be positioned at the 1st rotor plate 6 below supply port 2c, so the 1st rotor plate 6 makes normal button B from this position another mistake hour hands 90-degree rotation, sends a mouthful 7b and make this button B move to the 1st.As shown in Figures 3 and 4, the 1st send mouthful 7c under, the button maintaining part 8a of the 2nd swivel plate 8 on the 2nd turntable 5 falls if button B is sent a mouthful 7a from the 1st just in standby, it is kept by the button maintaining part 8a of the 2nd swivel plate 8.The 2nd swivel plate 8 and the 1st rotor plate 6 similarly are rotated counterclockwise, and the button B that will be kept by the button maintaining part 8a of the 2nd swivel plate 8 moves to the 2nd and sends a mouthful 9a.
As shown in Figure 1 to Figure 3, the 2nd send mouthful 9a below, the locking pin 14a of revoliving arm 14 is positioned at original state.In addition, the 2nd send mouthful 9a above button be set embed mechanism 15.If being arranged at the embedding rod 16 that this button embeds in mechanism 15 moves downwards, the Embedded Division 16a that embeds excellent 16 front ends contacts with button B, make on one side to embed rod 16 rotations, Yi Bian matched with the position of the locking pin 14a of revoliving arm 14 in the position of the sewing holes Ba of button B.Then, be arranged on the 2nd opening-closing plate of sending mouthful 9a place and open and close if make, and the sewing holes Ba of the locking pin 14a that makes revoliving arm 14 and button B locks, button B turns round and moves to the sewing machine base 50a of section that is configured on button sewing machine 50.
On the other hand, as shown in figure 17, if the surperficial back side and the damage condition of button B are abnormal, this button B is returned to button supply unit 2 (with reference to the S10 of Figure 17).In the present embodiment, as Fig. 4 and shown in Figure 5, the 1st rotor plate 6 from the supply port 2c of button supply unit 2 be rotated counterclockwise 1/4 week (90 degree) the position, namely button B taken and differentiated the surperficial back side of button B and the position of damage condition, sorting mouth 7a and opening-closing plate 11 are set.If the surperficial back side of button B and damage condition have extremely, this opening-closing plate 11 slides, and sorting mouth 7a opens, and makes button B fall and be positioned on belt conveyer 70 from sorting mouth 7a.Because the conveyer belt 70a of this belt conveyer 70 moves for orifice ring 2a towards button supply unit 2, so the button B that loads on belt conveyer 70 is returned to button supply unit 2 by the conveyer belt 70a of belt conveyer 70.
In addition, as previously mentioned, in the situation that do not wish button B is returned to button supply unit 2, replace belt conveyer 70 and the button returnable is set, the button B after differentiating all can be reclaimed.In addition, only that button B is damaged in the situation that can differentiate the abnormal of button B, discarded mouthful and opening-closing plate can be set in the position from this position Rotate 180 degree, and discarded container is set thereunder, only that this damaged button B is discarded, not that the button B of expectation state is returned to button supply unit 2 thereby will only have the surperficial back side of button B.
Thus, in the button automatic supplier 10 of present embodiment, button differentiating device 1 is differentiated the surperficial back side of button B exactly, and button sewing machine 50 is supplied with respectively automatically towards the button B of desired orientation in the surperficial back side of button B.Differentiation by finishing button B also moves it (with reference to S9 and the S10 of Fig. 7), finishes the motion flow of button automatic supplier 10 shown in Figure 17.
That is to say, button differentiating device 1 and button automatic supplier 10 according to the button sewing machine 50 of present embodiment, because can be corresponding to shape or the pattern of button B, strengthen reliably the contrast of the image of button B, so easily carry out the comparison of image and the discrimination standard image of button B.Therefore, there are not clearly concavo-convex or character shape even can play at the surperficial back side of button B, can differentiate exactly the effect at the surperficial back side of button B yet.
In addition, if the contrast of image strengthen because defect location that can clear and definite button B can be carried out the effect of the differentiation of damaged button B exactly so can also play.
In addition, the invention is not restricted to aforementioned embodiments etc., can carry out as required various changes.
For example, in the 1st turntable 4 of present embodiment, form respectively the 1st rotor plate 6 and the 1st base plate 7, but also can make both integrally formed.At this moment, the shape of button maintaining part 6a becomes circular port.For the 2nd turntable 5 also as hereinbefore.
In addition, button maintaining part 6a can not be also circle or circular hole shown in Figure 4, but for example forms the button path 2b of button supply unit 2 shown in Figure 1, not shown sliding stand or the large groove shape of track geometric ratio button B.For button maintaining part 6a, if consider compared with prior art can to select a greater variety of shapes, the shape of button maintaining part 6a also can change to greater than from button supply unit 2 until button sewing machine 50 and the form of the button supply unit 3 that arranges.In the present embodiment, for the configuration that makes circular bottom speculum 26 easy, make button maintaining part 6a form circle or circular hole with also matching, but in button maintaining part 6a, importantly in order respectively button B to be taken and button B to be remained on button maintaining part 6a, its shape might not determine the quality of taking.
