Description

  The present invention relates to a drawing apparatus and a drive control method of the drawing apparatus.

  2. Description of the Related Art Conventionally, a nail printing apparatus that includes a print head that performs printing by an inkjet method and prints a design image such as a color or a pattern on the surface of a human fingernail is known (see, for example, Patent Document 1).

  An ink jet print head performs printing by discharging ink from a nozzle provided on a surface facing a print target to land and fix the ink on a recording medium.

  By the way, since the ink jet print head has a small nozzle hole diameter, there is a restriction that it is impossible to use an ink containing a coloring material having a large particle diameter or an ink having a high viscosity. For this reason, there is a limit to the nail design that can be printed.

  On the other hand, although it is not a nail print device, it has a drawing head equipped with a pen, and the plotter method of drawing by moving the pen in the X and Y directions by bringing the tip of the pen into contact with a sheet (object) Printing devices are generally known. In the case of a pen, since the ink restriction is smaller than that in the case of an ink jet, it is considered that the width of the nail design can be expanded by using a plotter method using such a pen in a nail printing apparatus.

  However, when using a pen, the pen tip of the pen may become dry and the ink may not be discharged well, and the beginning of writing may be faded as it is, so try drawing prior to drawing a nail design on the nail. It is necessary to write and make the ink come out well. In this test writing, for example, it is necessary to perform an operation such as drawing a figure such as a circle several times on a sheet to improve the ink discharge.

  However, considering that the operation of drawing a circle in this test writing is performed by a plotter having an X, Y moving stage, it becomes a mechanical operation of moving the pen circularly by the X, Y moving stage. It takes some time to move in a circle, which takes a relatively long time to draw a circle, and a relatively long time to write a test. For this reason, in the case of a design requiring frequent pen replacement, there is a problem that it takes a relatively long time to form a nail design because the number of test writings increases.

  In the following embodiments, the drawing apparatus is described as a drawing target on the fingernail of the hand and drawn on the surface of the nail. However, the drawing target of the present invention is not limited to the fingernail of the hand. For example, a toe nail may be set as a drawing target.

(Configuration of the embodiment)
The basic configuration of the drawing apparatus will be described based on FIG. FIG. 1 is a top view of a drawing apparatus according to an embodiment, and is a cross-sectional view of a housing cut in the horizontal direction.

  As shown in FIG. 1, the drawing device 10 is a device that applies a nail design to the nail 12 of a human finger 11 by the drawing function of the drawing unit 30, for example. The drawing apparatus 10 includes a housing 20, a drawing unit 30 that is movably provided inside the housing 20, a finger insertion unit 13 that is provided at the center of the housing 20 and into which a finger 11 can be inserted, and a plurality of devices. And a plurality of caps 15 for protecting the pen tip of the pen 31. In addition, a medium holding unit 40 for holding a medium 41 having a flat upper surface (contact surface with which the pen 31 contacts) and having a disk shape, for example, is provided inside the housing 20 for trial writing. The medium 41 is made of, for example, paper.

  In the following description and drawings, when differently referring to a plurality of types of pens 31 and circles 62 drawn by a plurality of pens 31, pens 31 A, 31 B, 31 C, 31 D and circles 62 A, It is described as 62B, 62C, 62D, and when generally called, it is only described as the pen 31 and the circle 62.

  Although not shown, a touch panel type display unit including various flat displays such as a liquid crystal display (LCD: Liquid Crystal Display) and an organic electroluminescence display can be provided on the top surface of the housing 20. In addition, an image acquisition unit that acquires images of the finger 11 and the nail 12 inserted into the finger insertion unit 13 can be provided inside the housing 20, and the drawing device 10 uses the acquired image based on the acquired image. The nail design can be drawn on the nail 12 by the drawing unit 30.

  The drawing unit 30 can insert and remove the pen (drawing tool) 31 and the pen 31 that perform drawing on the nail (drawing target) 12 of the finger 11 inserted into the finger insertion unit 13 and placed in the finger insertion unit 13 And an arm 33 fixed to the pen holder 32. As shown in FIG. In the drawing unit 30, an optional pen 31 is selectively attached to the pen holder 32 from a plurality of types of pens 31A to 31D (for example, a plurality of types of pens having different types of colors) whose pen tips are fitted to the cap 15. It is possible to replace the pen 31 by doing. The arm 33 of the drawing unit 30 can be moved by a moving means 55 (described later) in the X direction that is the apparatus width direction, the Y direction that is the apparatus depth direction, and the Z direction that is the apparatus height direction (see FIG. 2). . As a result, the drawing unit 30 moves from the standby position (for example, a position in the vicinity of the cap 15) to above the cap 15 to select and hold the arbitrary pen 31, and moves and descends on the medium 41 to perform test writing. Then, the finger insertion unit 13 moves and descends to the upper opening 13a and draws a nail design on the nail 12 with the pen tip.

  As shown in FIG. 2, the medium holding unit 40 includes a tray 42 that can move in and out through an opening 21 provided in a peripheral wall (for example, a side wall) of the housing 20, and a holding member 43 attached on the tray 42. And a rotation drive unit 45 for rotating the holding member 43. The rotation drive unit 45 includes a drive unit 45a (for example, an electric motor) fixed in the housing 20, and a drive gear 45b provided at the upper end of the drive unit 45a. In the medium holding unit 40, in the state where the tray 42 is inserted into the inside of the housing 20, the test writing can be performed on the medium 41 on the holding member 43, and in the state where it is pulled out to the outside of the housing 20, 41 can be exchanged. The exchange of the medium 41 is performed when the test writing is performed on almost the entire surface of the medium 41 and the space for the test writing on the medium 41 is almost exhausted.

  As shown in FIG. 3, the tray 42 has a rectangular shape in a plan view, and has a flat plate portion 42a whose upper surface is flat and provided substantially horizontally, and a shaft hole 42b provided in the central portion of the flat plate portion 42a. The flat plate portion 42a has a first upright wall 42c provided at an end portion on the device outer side in the X direction, and a second upright wall 42d provided at an end portion on the inward direction of the device in the X direction.

  The holding member 43 is a member that holds the medium 41 and has, for example, a circular shape in a plan view, and has a flat upper surface except a grip portion 43b described later. The flat plate portion 42 a of the tray 42 has a through hole 43 a at the center and is detachably fitted between the first upright wall 42 c and the second upright wall 42 d of the tray 42. It is provided so that it can rotate. Thus, when the medium 41 is held by the holding member 43, the upper surface of the medium 41 is a plane perpendicular to the pen 31. Further, the holding member 43 has a gripping portion 43b on the outer peripheral edge thereof for pressing and gripping the outer peripheral portion of the medium 41 from above. Furthermore, the static friction coefficient of the surface of the holding member 43 that contacts the medium 41 is set to a value that does not cause the medium 41 to slide on the holding member 43 during trial writing with the pen 31. In order to obtain a static friction coefficient having such a value, for example, it is effective to form the surface of the holding member 43 with a rubber material or the like.

  Here, in consideration of the ease of exchanging the medium 41, the configuration in which the disc-shaped holding member 43 is detachably attached to the tray 42 is illustrated, but the holding member 43 does not necessarily need to be detachable. The tray 42 may not be detachable. Further, the planar shape of the medium 41 and the holding member 43 may be a polygon such as a hexagon or an octagon in addition to a circle.

  The rotation shaft 45c is inserted into the shaft hole 42b from below. The upper end 45c1 of the rotation shaft 45c is formed in an irregular shape (for example, a rectangular shape such as a rectangle) in a plan view that can be fitted to the through hole 43a of the holding member 43 and engageable in the rotational direction. At the lower end portion of the rotation shaft 45c, a driven gear 45d is provided that meshes with the drive gear 45b when the tray 42 is inserted into the housing 20. When the tray 42 is positioned in the housing 20, the rotation shaft 45c is rotated by the power from the drive means 45a via the drive gear 45b and the driven gear 45d, and is rotated by the upper end 45c1 fitted in the through hole 43a. The holding member 43 is rotated. The rotation shaft 45 c and the driven gear 45 d are elements constituting the rotation drive unit 45.

  In the center of the medium 41, an insertion hole 41a of a different shape (for example, a square such as a rectangle) into which the upper end 45c1 is inserted may be provided so as to be aligned with the upper end 45c1 of the rotational shaft 45c. Further, in this example, the upper end 45c1 of the rotating shaft 45c and the through hole 43a of the holding member 43 are made square or polygonal so that the holding member 43 does not slip during rotation, but it is generally used for a known CD drive or DVD drive. When a mechanism (a mechanism for gripping and rotating the rotating body) is employed, the through hole 43a of the holding member 43 may be a circular hole or the like.

  Subsequently, a control configuration of the drawing device 10 will be described based on FIG. FIG. 4 is a block diagram showing the configuration of control.

  As shown in FIG. 4, the control device 50 includes a control unit 51 configured by a CPU (Central Processing Unit), and a storage unit 56 configured by a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Prepare.

  The control unit 51 includes a drawing control unit 52 and a rotation control unit 53. The functions of the drawing control unit 52 and the rotation control unit 53 are realized by the cooperation of the CPU of the control unit 51 and the programs stored in the ROM of the storage unit 56. Further, the control unit 50 is connected to the drawing unit 30 and the medium holding unit 40.

  The drawing control unit 52 controls the operation of the pen 31 (more specifically, the operation of the arm 33) via the moving means 55 having the X and Y moving stages, and draws the nail design on the nail 12 by the pen 31. The pen 31 is moved to the medium 41, or the pen 31 is moved above the medium 41 or above the medium 41 during trial writing. In addition, the rotation control unit 53 controls the operation of the driving unit 45 a in the trial writing of the pen 31, and the rotation angle and rotation speed of the medium 41 according to the distance necessary for the trial writing set in each pen 31. Control the direction of rotation.

(Operation of the embodiment)
Subsequently, a drive control method of the drawing apparatus 10 will be described based on FIG. 5 and FIG. FIG. 5 is a flowchart of the drive control method, and FIG. 6 is an explanatory diagram of the operation of the medium holding unit.

  As shown in FIG. 5, in this drive control method, first, in step S1, the pen 31 to be used determines whether or not trial writing is necessary. If trial writing is not necessary, the process proceeds to step S 7, and after the pen 31 is moved above the nail 12 by the drawing unit 30, the pen tip is lowered to the nail 12. Then, in step S8, a nail design is drawn on the nail 12. On the other hand, if trial writing is required, the process proceeds to step S2.

  In step S2, the holding member 43 and the medium 41 are rotated by the driving means 45a, for example, in the clockwise rotation direction 63 (see FIG. 6), and the medium 41 is rotated and moved. Next, in step S3, the pen 31 is moved above a pen lifting / lowering area 60 (see FIG. 6), which will be described later, and then the pen tip is lowered with respect to the rotating medium 41, and the pen tip contacts the medium 41. Let Then, necessary test writing is performed on the medium 41 in step S4. As a result, test writing is performed so as to draw a circle 62 on the medium 41. At this time, as will be described later, trial writing at the same position can be prevented by appropriately moving the pen tip.

  In step S5, the drive means 45a is controlled to stop the rotation of the holding member 43 and the medium 41. In step S6, the pen 31 is raised and returned to a specified position (for example, a standby position). In step S7, the pen 31 is moved above the nail 12, and then the pen tip is lowered to the nail 12. In step S8, a nail design is drawn on the nail 12.

Here, the method of trial writing in step S4 will be described more specifically.
As shown in FIG. 6, for example, in the medium 41, an area extending in the radial direction of the medium 41 in the arrangement direction of the caps 15 (X direction in this example) and the area as close as possible from the cap 15 is a pen lifting area. 60 (a rectangular area surrounded by a two-dot chain line in FIG. 6), and within the range of the pen raising and lowering area 60, test writing of the plurality of pens 31A to 31D (lifting of each pen at the time of test writing) Set to be displayed. The position where each pen 31 is moved up and down is arbitrary as long as it is within the pen lifting area 60.

  In FIG. 6, the pen 31A corresponds to the position 61A of the pen lifting area 60, the pen 31B corresponds to the position 61B of the pen lifting area 60, the pen 31C corresponds to the position 61C of the pen lifting area 60, and the pen 31D is the pen. The example corresponding to position 61D of the raising / lowering area | region 60 is shown. In this case, the respective pens 31 can be moved to abut on the medium 41 with a small amount of movement, and furthermore, the pens 31 different in color can be positioned on different rotational trajectories (circles 62) of the medium 41. There is no fear that the colors of the ink will be mixed between the pens 31 of mutually different colors, and trial writing can be performed many times on the same orbit.

However, if too many test writings are performed at the same position, for example, a state in which part of the ink attached to the medium 41 is transferred to the pen point and the ink adheres excessively to the pen point, causing problems in subsequent drawing. There is also concern that this will occur. For this reason, when performing test writing, the pen 31 may be moved in the X direction within the range of the pen raising and lowering area 60 so that double writing is not performed at the same position. In this case, for example, as shown in FIG. 7, during trial writing, the pen tip is moved little by little from the center side of the medium 41 to the outer periphery side or from the outer periphery side to the center side. In the medium 41, a large number of circles 62 are drawn with almost no gap. In such a case, the space of the medium 41 can be maximized, and as a result, the space in the housing 20 can be saved, and the waste of the medium 41 and the trouble of exchanging the medium can be minimized.
Further, it is necessary to change the position of the trial writing when the trial writing is performed on the entire circumference of the circle 62 on the medium 41 and to replace the medium 41 when the trial writing is performed on almost the entire surface of the medium 41. In consideration of this, it is preferable to dispose the pen 31 having a higher frequency of use at an outer position (e.g., the position 61C or 61D in FIG. 6) where the circumferential length in the pen lifting area 60 is long.

Note that the area for raising and lowering the pen 31 is not particularly limited to the pen raising and lowering area 60 and can be arbitrarily changed. In which area the pen 31 is raised or lowered in the medium 41 is controlled by a program. It can be done as appropriate.
Further, for example, the photographing unit may be provided above the medium 41, and the test writing may be performed on the unused area by recognizing the unused area where the test writing is not performed by the photographing unit.
In addition, when the area where test writing is performed on the medium 41 reaches a certain level or more (for example, when the circle 62 is drawn on the majority of the medium 41), the test writing operation is stopped and an instruction to urge replacement of the medium 41 is notified. Control may be performed.

(Effect of the embodiment)
As described above, according to the embodiment described above, in the trial writing, the circle 62 is drawn by the rotation operation of the medium 41 using a motor or the like. The circle 62 (distance) required for test writing can be drawn more quickly than in the case of a mechanical operation of moving it in a circular manner. As a result, even in the case of a nail design that requires frequent replacement of the pen 31, the time required for test writing can be relatively shortened, and the time required for forming a nail design can be relatively shortened. Can.

  Further, in the present embodiment, in the mechanism for performing the trial writing, the range in which the drawing unit 30 including the pen 31 is moved especially on the upper side of the medium 41 is narrower than the case of performing the trial writing by moving the drawing unit itself in a circular motion. can do. Therefore, in the space above the medium 41, a space (for example, a space excluding the pen lifting area 60) that does not have the possibility of interfering with the drawing unit 30 can be secured more than in the case of circular movement of the drawing unit itself. For this reason, it becomes possible to arrange other parts etc. in the space which does not have the possibility of interfering with the drawing unit 30, and to make effective use of the space.

  In the embodiment, the example in which the test writing is performed so as to draw the circle 62 by rotating the medium 41 in the clockwise rotation direction 63 is described. However, the rotation operation of the medium 41 is limited to rotation in one direction. Instead, for example, test writing may be performed so as to draw a zigzag locus by moving the medium 41 so as to repeat counterclockwise rotation and clockwise rotation.

  In the embodiment, the medium 41 is rotated to draw a locus on the medium 41 by the pen 31 whose position is fixed. In short, the medium 41 moves relative to the pen 31. Just do it. That is, in addition to the configuration in which the medium 41 is rotated by the rotation mechanism, for example, the medium 41 may be moved (for example, reciprocated) along one direction.

  In the embodiment, the configuration in which the entire tray 42 enters and exits the housing 20 is illustrated, but the entire tray 42 does not necessarily have to enter and exit from the housing 20, for example, about half of the tray 42. In this case, the medium 41 can be exchanged.

  Further, the test writing may be performed not only by the movement of the medium 41 by a rotation operation or the like, but also by performing the test writing while moving the pen 31 linearly in the pen lifting / lowering area 60, for example.

  Furthermore, in the embodiment, the case where the pen 31 is used has been described, but the drawing apparatus 10 may include a printing unit having an inkjet head in addition to the pen 31.
