In the nail drawing device having such a configuration, the nail region detecting means configured to include the light emitting element and the light receiving element detects the nail region. The light emitting element irradiates light to a detection area including a nail and a part other than the nail, such as skin, but the nail has a reflectance different from that of the part other than the nail, so that the reflection from the detection area By receiving the light by the light receiving element, the nail region detecting means can detect the nail region without being confused with a portion other than the nail. Since the drawing means draws the nail area detected by the nail area detecting means as the drawing area, according to the nail drawing apparatus as described above, the drawing means draws on a part other than the nail such as the skin. In addition, it is possible to appropriately draw only on the nails.
Further, the nail region detection unit detects the nail region when drawing on the nail by the drawing unit. At this time, the nail imaging is not performed as in the nail drawing device of Patent Document 1. Therefore, it is not necessary to provide an expensive video camera or display that is included as a component in the nail drawing device of Patent Document 1, and it is sufficient to provide an inexpensive light emitting element and light receiving element.

To draw on the nails. Here, the virtual line can be set freely as appropriate. For example, as described later, four straight lines passing through the four positions may be set as virtual lines to set a rectangular drawing area, or an equation determined according to detection data of the four positions. The drawing region may be set by setting the locus of the point satisfying the virtual line (however, passing through the four positions).

  According to the nail drawing device as described above, when detecting the nail region, the nail region detecting means only needs to detect the four positions of the left end, the right end, the front end, and the base end of the nail. The nail region can be detected efficiently at low cost.

  Further, in the nail drawing device of the present invention, the nail area detecting means is separated from each other along the nail width direction connecting the left end and the right end of the nail, and at least one of them is provided so as to be movable along the nail width direction.

For this reason, when the finger F is pressed against the inner peripheral surface 22F and fixed, the distance between the nail N and the drawing unit 7 is kept constant (G).

  As shown well in FIG. 2, the drawing area setting mechanism 5 has three pairs of movable elements arranged sequentially along the length direction of the nail N (in FIG. 2, the horizontal direction: hereinafter referred to as the nail length direction). A plate pair 51, 52, 53 is included. Each movable plate pair 51, 52, 53 can be viewed from the outside through a transparent window 54 formed on the upper surface of the apparatus body 2.

  The movable plate pair 51 is configured by two movable plates 51L and 51R. Each of the movable plates 51L and 51R is provided so as to be movable along the width direction of the claw N (vertical direction in FIG. 2; hereinafter referred to as claw width direction) orthogonal to the claw length direction. Here, each movable plate 51L, 51R is configured to be interlocked with each other, and when the user operates a predetermined operation switch in the operation unit 8 provided on the upper surface of the apparatus body 2, both the movable plates 51L, 51R. Are moved along the claw width direction symmetrically with respect to the central axis A along the claw length direction. For this reason, it is possible to adjust the space | interval along the nail | claw width direction of the movable plate pair 51 by a user's operation. The central axis A is a line written on the finger placement unit 3 and is used as an index when positioning the finger F placed on the finger placement unit 3.

  Similarly, the movable plate pairs 52 and 53 are respectively constituted by two movable plates 52L, 52R and 53L, 53R that are movably provided along the claw width direction. The movable plates 52L, 52R and the movable plates 53L, 53R are configured to be linked to each other, and the movable plates 52L, 52R, 53L, and 53R are claws symmetrically with respect to the central axis A by a user operation.

The user operates the operation unit 8 while viewing the movable plate pair to be adjusted in space and the nail N to be drawn through the window 54, so that the interval between the movable plate pair matches the width of the nail N, and The ends of the two movable plates are aligned with the left and right ends of the nail N (S3).
In the example of FIGS. 3 and 4 where the nail of the little finger is to be drawn, the distance between the movable plate pair 53 is adjusted to match the width of the nail N of the little finger in S3. At this time, the right end of the movable plate 53L is aligned with the left end of the nail N, and the left end of the movable plate 53R is aligned with the right end of the nail N.
As described above, when the distance between the movable plate pairs is matched with the width of the claw N, the user determines the distance between the movable plate pairs by operating the operation unit 8.

  When the distance between the movable plate pair is determined, the optical sensor 6 moves integrally with the drawing unit 7, and the position of each end of the two movable plates in the movable plate pair whose distance is determined in S3, and the drawing target. The position of the tip of the nail N is detected (S4).

  As described above, since the individual movable plates constituting the movable plate pair have remarkably different reflectances from the other portions, the optical sensor 6 confuses the two movable plates with other portions. And the position of each end (left and right ends in FIG. 4) of the two movable plates can be accurately detected.

  Further, the position of the tip of the nail N to be drawn is detected based on a change in the detected light amount in the region 61 of the width W centered on the central axis A described in the finger placement unit 3 in the optical sensor 6. be able to. That is, when the optical sensor 6 moves toward the nail N along the nail length direction (see the arrow in FIG. 4), the region 61 is moved to a position facing the tip of the nail N (FIG. 4). Since the amount of light received by the light receiving elements included in the region 61 changes abruptly, the position of the tip of the nail N can be accurately detected.

  Note that the width W of the region 61 is set to be smaller than the minimum distance between the movable plate pairs 51, 52, 53, and even when the distance between the movable plate pairs 51, 52, 53 is minimized. The region 61 is not opposed to each movable plate in each movable plate pair. For this reason, only the nail | claw N can be detected now in the area | region 61, and the position of the front-end | tip of the nail | claw N can be detected correctly.

Subsequently, the drawing unit 7 sets a drawing area based on the position detection data obtained by the optical sensor 6 acquired in S4 (S5).
FIG. 6 shows a drawing area P set by the drawing unit 7. As shown in this figure, the drawing area P is sandwiched between two virtual straight lines T1 and T2 parallel to each other along the nail length direction, and two virtual straight lines U1 parallel to each other along the nail width direction. , U2 is a rectangular area.

  The virtual straight lines T1 and T2 are straight lines in the claw length direction passing through the positions of the ends of the two movable plates in the movable plate pair detected by the optical sensor 6 in S4. Here, since the left and right ends of the claw N are aligned with the ends of the two movable plates in S3 (see FIG. 4), the virtual straight lines T1 and T2 indicate the positions of the left end and the right end of the claw N, respectively. Passing through.

The virtual straight line U1 is a straight line in the nail width direction passing through the position of the tip of the nail N detected by the optical sensor 6 in S4.
The virtual straight line U2 is a straight line in the claw width direction passing through the position of the base end of the claw N. Although the position of the base end of the nail N is not directly detected by the optical sensor 6 in S4, the base end of the nail N is aligned with the boundary lines B1, B2, B3 in S2, so that the boundary Based on the positions of the lines B1, B2, and B3, the optical sensor 6 can indirectly detect the position of the base end of the nail N. Therefore, the drawing unit 7 can set a virtual straight line U2 that passes through the position of the base end of the nail N. The virtual straight line U2 is a straight line obtained by extending the boundary lines B1, B2, and B3 where the base ends of the claws N are aligned in S2. In the example of FIG. 4 in which the nail of the little finger is drawn, since the base end of the nail N is aligned with the boundary line B3 in S2, the virtual straight line U2 is obtained by extending the boundary line B3.

  As described above, since the virtual straight lines T1, T2, U1, and U2 pass through the positions of the left end, right end, tip, and base end of the drawing target nail N, the rectangular drawing region P surrounded by these is The entire nail N is included and the size is almost equal to that of the nail N.

  Finally, the drawing unit 7 draws the drawing pattern selected by the user on the nail N included in the drawing area P set in S5 (S6).

  In the nail drawing device 1 as described above, the drawing area setting mechanism 5 and the optical sensor 6 constitute nail area detecting means for detecting the nail N area.

  Further, the left movable plates 51L, 52L, 53L in each movable plate pair 51, 52, 53 are provided so as to be movable along the claw width direction, and a claw left end mark member to which the left end of the drawing target claw N is aligned is provided. Further, the right movable plates 51R, 52R, 53R in each movable plate pair 51, 52, 53 are provided so as to be movable along the nail width direction, and the right end of the nail N to be drawn is matched. The nail right end mark member is configured. As described above, each of the movable plate pairs 51, 52, 53 constitutes a claw width mark member pair including a claw left end mark member and a claw right end mark member. In particular, the movable plate pair 51 constitutes a nail width mark member pair for thumb, the movable plate pair 52 constitutes a nail width mark member pair for index finger / middle finger / ring finger, and the movable plate pair 53 constitutes a nail for little finger. A width mark member pair is formed.

  Further, the movable plate pairs 51, 52, and 53 that form boundary lines B1, B2, and B3 where the base ends of the claws N to be drawn are aligned and a part of the apparatus main body 2 constitute the base end mark member. ing. In particular, the movable plate pair 51, 52 forming the boundary line B1 constitutes a nail base mark member for the thumb, and the movable plate pair 52, 53 forming the boundary line B2 is the index finger / middle finger / ring finger. A nail base end mark member is formed, and the movable plate pair 53 and a part of the apparatus main body 2 forming the boundary line B3 constitute a little finger nail base end mark member.

<Effect of embodiment>
According to the above embodiment, the following effects can be obtained.
The drawing unit 7 draws the area of the nail N detected by the optical sensor 6 as the drawing area P. Therefore, the drawing unit 7 appropriately draws only the nail N without drawing on a part other than the nail N such as the skin S. It can be carried out.

  Further, for drawing on the nail N by the drawing unit 7, the position of each end of the nail N to be drawn is detected by the optical sensor 6. There is no visualization. Therefore, it is not necessary to provide an expensive video camera or display that is included as a component in the nail drawing device of Patent Document 1, and it is sufficient to provide an inexpensive optical sensor 6, and thus the nail drawing device 1 is manufactured at a low cost. can do.

  Further, when detecting the area of the nail N, the optical sensor 6 only needs to detect the four positions of the left end, the right end, the distal end, and the base end of the nail N, so that the detection time can be shortened, and the low The area of the nail N can be detected efficiently at a low cost.

  Further, the optical sensor 6 does not rely on the reflected light from the nail N or the skin S, which has a difference in reflectance depending on the individual, but based on the reflected light from the objective movable plate pair 51, 52, 53, Since the positions of the left and right ends are detected, the positions of the left and right ends of the nail N can be detected with high accuracy without confusion between the nail N and a portion other than the nail such as the skin S. Therefore, since the drawing area P can be set by the virtual straight lines T1 and T2 that accurately pass through the positions of the left and right ends of the nail N, drawing on the nail N can be performed with high accuracy.

  In addition, since each of the movable plates 51L, 51R, 52L, 52R, 53L, and 53R constituting the movable plate pair 51, 52, and 53 has a remarkably different reflectance from the other portions, the optical sensor 6 can accurately discriminate each movable plate without being confused with other parts, and can accurately detect the positions of the left and right ends of the claw N.

  Also, once the distance between the three movable plate pairs 51, 52, 53 is adjusted to the nail width of a certain user's thumb, the index finger / middle finger / ring finger nail width, and the nail width of the little finger, the same user However, when the nail drawing device 1 is used, the nail N to be drawn at each end of the two movable plates in each of the movable plate pairs 51, 52, 53 whose interval is already adjusted according to the nail width of each finger. Therefore, it is not necessary to readjust the distance between the movable plate pairs 51, 52, 53. Therefore, drawing on the nail of each finger of the same user can be performed quickly, and usability can be improved.

  Note that the nail width data of each finger of each user can be stored in the memory by operating the operation unit 8. In this case, when a predetermined reading operation of the operation unit 8 is performed by the user who intends to use the nail drawing device 1, the nail width data of each finger of the user stored in the memory is read, and each movable plate The interval between the pair 51, 52, 53 is automatically adjusted to match the value of the nail width data of each finger read out. As described above, once the nail width data of each finger of the user is stored in the memory, the interval between the pair of movable plates 51, 52, and 53 can be set by simply performing the reading operation of the nail width data. Since it can be adjusted for the user, drawing on the nail can be started quickly, and the nail drawing device 1 that is easy to use can be provided.

  Moreover, since the space | interval of each movable plate pair 51,52,53 can be adjusted according to the nail width | variety of each user, the highly versatile nail | claw drawing apparatus 1 which can be used for all users can be provided. .

  Further, the optical sensor 6 determines the position of the base end of the nail N based on the objective boundary lines B1, B2, and B3 without depending on the reflected light from the nail N or the skin S having a difference in reflectance depending on individuals. Since the detection is performed, the position of the base end of the nail N can be detected with high accuracy without confusing the nail N with a portion other than the nail N such as the skin S. Therefore, since the drawing area P can be set by the virtual straight line U2 that accurately passes through the position of the base end of the nail N, drawing on the nail N can be performed with high accuracy.

  In addition, since the drawing area P can be set by two simple virtual straight lines T1 and T2 that respectively pass through the left and right ends of the drawing target nail N, the configuration of the drawing unit 7 that sets the drawing area P is simplified. In addition, the time required for setting the drawing area P can be shortened, and drawing on the nail N can be performed efficiently.

  Further, since the drawing area P can be set by two simple virtual straight lines U1 and U2 that respectively pass through the respective positions of the tip base end of the drawing target nail N, the configuration of the drawing unit 7 for setting the drawing area P is simplified. In addition, the time required for setting the drawing area P can be shortened, and drawing on the nail N can be performed efficiently.

  Further, since the finger F placed on the finger placement unit 3 is pressed against and fixed to the finger fixing unit 22F arranged at a certain distance G from the drawing unit 7 by the biasing spring 4, the finger F is fixed. The distance between the nail N of F and the drawing unit 7 can be kept constant (G), and drawing on the nail N by the drawing unit 7 can be performed with high accuracy.

  In addition, since the finger placement portion 3 biased by the biasing spring 4 presses the finger F against the finger fixing portion 22F, the finger is firmly placed between the finger placement portion 3 and the finger fixing portion 22F. And can be fixed.

  In addition, since the finger placement unit 3 is provided so as to be movable and the interval between the finger placement unit 3 and the finger fixing unit 22F can be adjusted, the finger placement unit 3 can be mounted regardless of the size of the finger F. The finger F can be fixed between the placement unit 3 and the finger fixing unit 22F, and the highly versatile nail drawing device 1 can be provided.

  Moreover, since the finger insertion hole 22 for inserting the finger F can also be used as the finger fixing portion 22F, the configuration of the nail drawing device 1 can be simplified, and the manufacturing cost of the nail drawing device 1 can be reduced. it can.

  Further, since the center axis A visible from the outside through the window 54 is described in the finger placement unit 3, the center position of the nail N can be easily and accurately performed with reference to the center axis A.

  Further, the boundary lines B1, B2, and B3 in the claw width direction formed by sequentially arranging the movable plate pairs 51, 52, and 53 along the claw length direction are used as marks for aligning the base end of the claw N as it is. Since it can be utilized, it is not necessary to provide a separate nail base mark member, and the manufacturing cost of the nail drawing device 1 can be reduced.

  Further, since the movable plate pair 52 can be used as a common nail width mark member pair for the three finger nails of the index finger / middle finger / ring finger having substantially the same size, the three fingers of the index finger / middle finger / ring finger. There is no need to provide a pair of nail width mark members for each finger, the configuration of the nail drawing device 1 can be simplified, and the manufacturing cost can be reduced.

  In addition, since the boundary line B2 can be used as a common mark that matches the base ends of the three finger nails of the index finger / middle finger / ring finger having substantially the same size, the three of the index finger / middle finger / ring finger can be used. There is no need to provide a mark for aligning the base end of the nail for each finger, the configuration of the nail drawing device 1 can be simplified, and the manufacturing cost can be reduced.

  In addition, since the two movable plates in each of the movable plate pairs 51, 52, 53 are configured to move symmetrically with respect to the central axis A, the nail N whose center coincides with the central axis A The distance between each pair of movable plates 51, 52, 53 can be easily and accurately adjusted according to the width.

  Further, since the transparent window 54 is provided, the positioning of the nail N and the adjustment of the distance between the movable plate pairs 51, 52, 53 can be accurately performed while being visually recognized from the outside.

  Further, since the window 54 that covers the movable plate pair 51, 52, 53 is provided, the possibility that dust and the like adhere to the movable plate pair 51, 52, 53 from the outside can be reduced, and based on the dust. The occurrence of erroneous detection in the optical sensor 6 can be prevented.

  Further, the optical sensor 6 can detect the positions of the left and right ends of the claw N using the movable plate pairs 51, 52, 53, and the amount of light received by the light receiving element included in the region 61 with the width W The position of the tip of the nail N can be detected based on the above, and the position of the base end of the nail N can be detected using each of the boundary lines B1, B2, B3. Thus, since one optical sensor 6 can detect the four positions of the left end, the right end, the distal end, and the proximal end of the nail N at a time, there is no need to provide four optical sensors for detecting each end position. The configuration of the nail drawing device 1 can be simplified, and the manufacturing cost of the nail drawing device 1 can be reduced.

<Modification>
The present invention is not limited to the embodiment described above, and any modification of this embodiment within the scope that can achieve the object of the present invention is included in the technical scope of the present invention.

  For example, in the above-described embodiment, when detecting the nail N region, the movable plate pairs 51, 52, 53 as the nail width mark member pair to which the left and right ends of the nail N are aligned, and the base end of the nail N are aligned. Although the boundary lines B1, B2, and B3 were used, the area of the nail N is directly detected by the optical sensor 6 without using such movable plate pairs 51, 52, and 53 and the boundary lines B1, B2, and B3. You can also That is, the light emitting element in the optical sensor 6 irradiates light to a detection region including the nail N and a part other than the nail N such as the skin S, but the nail N has a reflectance different from that of the part other than the nail N. Therefore, by receiving the reflected light from the detection area by the light receiving element, the optical sensor 6 can detect the area of the nail N without being confused with a part other than the nail N. Since the drawing unit 7 performs drawing using the area of the nail N detected by the optical sensor 6 as a drawing area, only the nail N is appropriately applied without drawing on a portion other than the nail N such as the skin S. Can draw.

  In the embodiment, only the four positions of the left end, the right end, the distal end, and the base end of the nail N are detected by the optical sensor 6, but the entire contour line of the nail N may be detected by the optical sensor 6. . In this case, although the configuration of the optical sensor 6 is complicated, if the area surrounded by the outline detected by the optical sensor 6 is set as the drawing area by the drawing unit 7, the drawing area and the area of the nail N are completely set. Since they can be matched, the drawing accuracy on the nail N can be remarkably improved.

  In the above embodiment, the rectangular area surrounded by the virtual straight lines T1, T2, U1, U2 passing through the positions of the left end, the right end, the tip, and the base end of the nail N detected by the optical sensor 6 is shown in the drawing unit 7. Although set as the drawing area P, for example, a locus of points satisfying an equation determined according to detection data at each position of the left end, right end, tip, and base end of the nail N (however, the left end, right end, tip of the nail N , Passing through four positions at the base end) may be set as the drawing area. In this case, the configuration of the drawing unit 7 for setting the drawing area is complicated, but if an equation for setting the drawing area is appropriately set, an area closer to the area of the nail N is set as the drawing area. Therefore, the drawing accuracy on the nail N can be improved.

  In the embodiment, the two movable plates in each of the movable plate pairs 51, 52, 53 used as the claw width mark member pair are configured to be movable. In order to match the width of the nail N to be drawn, at least one of the nail left end mark member and the nail right end mark member in the nail width mark member pair may be configured to be movable. In particular, when only one of the two mark members in the pair of claw width mark members is configured to be movable, the position of the other mark member is fixed because the position of the other mark member is fixed. The position does not need to be detected by an optical sensor, and the positions of the left and right ends of the nail N can be detected only by detecting the position of the one mark member by the optical sensor.

  Moreover, in the said embodiment, if the optical sensor 6 provided so that movement was possible to each position facing each movable plate pair 51,52,53, each movable plate pair 51,52,53 will be comprised. Although it is configured to detect the position of the movable plate, it is not necessary to provide the optical sensor 6 so as to be movable, and it may be configured to detect the position of each movable plate while the optical sensor 6 is fixed. Is possible.

  Moreover, in the said embodiment, although the optical sensor 6 and the drawing unit 7 were comprised integrally, you may comprise both as separate bodies.

  In the above-described embodiment, three pairs of movable plate pairs used for the nail width mark member pair are provided for the thumb, index finger / middle finger / ring finger, and little finger, but there are several pairs of nail width mark member pairs. May be. For example, when only one pair of nail width mark member pairs is provided, the interval between the nail width mark member pairs may be adjusted according to the width of the nail N every time the nail N to be drawn is changed. Further, when five pairs of nail width mark member pairs are provided corresponding to the individual fingers from the thumb to the little finger, once the nail width mark member pair interval is adjusted to the nail width of each finger, Thereafter, when the same user uses, the nail to be drawn should be aligned with each nail width mark member pair whose interval is already adjusted according to the nail width of each finger. There is no need to readjust the interval.

  In the above embodiment, the boundary lines B1, B2, and B3 are configured as marks for aligning the base ends of the claws with a small gap. For example, the base ends of the claws are provided on the movable plate pairs 51, 52, and 53, for example. The mark for aligning may be directly described.

  Moreover, in the said embodiment, the optical sensor 6 is comprised so that the position of the base end of the nail | claw N may be detected indirectly based on boundary line B1, B2, B3 in which the base end of the nail | claw N was match | combined. However, the optical sensor 6 may be configured to directly detect the position of the base end of the nail N. In this case, the nail proximal mark member having a remarkably different reflectance from the other portions is aligned with the proximal end of the nail N, and the optical sensor 6 detects the proximal end of the nail N based on the reflected light from the nail proximal end mark member. You may comprise so that a position may be detected. Further, the position of the base end of the nail N can be detected without providing the base end mark member. In this case, if light is emitted to the detection region including the proximal end of the nail N and the skin S adjacent to the light emitting element in the optical sensor 6, the reflectance of the nail N and the skin S is different. 6 can discriminate between the nail N and the skin S based on the light reception data of the light receiving element that has received the reflected light from the detection region, and can detect the position of the base end of the nail N.

In the embodiment, the boundary lines B1, B2, and B3 are formed as marks for detecting the position of the base end of the nail N, while the marks for detecting the position of the tip end of the nail N are formed. The nail tip mark member for detecting the position of the tip of the nail and the nail tip mark member for detecting the position of the tip of the nail are formed together with the nail length mark member pair. The optical sensor 6 may be configured to detect the positions of the tip end and the base end of the nail N based on the reflected light from the pair of nail length mark members.
Here, the claw tip mark member and the claw base end mark member are separated from each other along the claw length direction, and at least one of them is provided so as to be movable along the claw length direction. As a result, both mark members are respectively aligned with the tip and the base end of the nail N so that the distance between the nail length mark member pair can be matched with the length of the nail N, and the reflection from the nail length mark member pair Based on the light, the optical sensor 6 can accurately detect the positions of the distal end and the proximal end of the nail N without confusing the nail N with portions other than the nail N.
The nail length mark member pairs include three nail length nail length mark member pairs, a nail length mark member pair for the index finger / middle finger / ring finger, and a nail length mark member pair for the little finger. It is preferable to provide a length mark member pair. According to such a configuration, once the interval between the nail length mark member pairs is once adjusted to the nail length of each finger of a certain user, when the same user uses it thereafter, It is only necessary to align the tip base end of the nail to be drawn with each nail length mark member pair whose interval is adjusted according to the nail length, so that it is not necessary to readjust the interval between each nail length mark member pair. .

  In the above embodiment, the inner peripheral surface 22F on the drawing unit 7 side in the finger insertion hole 22 is a finger fixing portion for fixing the finger F. However, the finger fixing portion is configured separately from the finger insertion hole 22. May be.

  Moreover, in the said embodiment, although the monitor 9 which displays various information was provided, the monitor 9 does not need to be provided. Further, various types of information may be displayed on a display or the like externally attached to the nail drawing device 1 via the interface 10 instead of the monitor 9.
