Description

The present invention relates to a drawing apparatus.

Conventionally, a drawing device for drawing a nail design on a fingernail or the like is known.
In such a drawing device, it is necessary to save the fingers other than the drawing finger (that is, the undrawn finger and the already drawn finger for which the drawing process has already been completed) to a position that does not affect the drawing.
As a place to evacuate, for example, it is conceivable to provide an evacuation space below the finger resting portion on which the finger for drawing (the fingernail of the finger) is placed.
However, in this case, there is a risk that the nail may come into contact with the back surface of the finger resting portion, and especially when the retracted finger includes a already drawn finger, the drawn nail design is inside the device. It may be rubbed off or soiled.
In addition, depending on the finger to be drawn, if a finger other than the finger to be drawn is retracted below the finger resting portion, the balance of the finger on the finger resting portion becomes unbalanced, and the finger tends to move or shift during drawing. There is a possibility.

Therefore, it is conceivable to draw on the fingernail of the finger to be drawn in a state where the finger other than the finger for drawing is placed flat alongside the finger for drawing on the finger resting portion (see, for example, Patent Document 1). ).

Special Table 2003-534083

However, when drawing, the drawing head moves not only above the nail, which is the drawing target, but also above the front, back, left, and right areas. Therefore, when a finger that is not the drawing target is placed flat on the finger rest. , The drawing head may move over these fingers.
The fingers to be drawn and their nails are fixed by some method so that their positions do not shift during drawing, but the fingers that are not to be drawn are generally not fixed.
Since the distance between the drawing head that draws and the nail is very small, if the user consciously or unconsciously moves a finger that is not the drawing target, the drawing head or the mechanism that moves it will come into contact with the finger and the finger will be injured. In addition to this, there may be a situation in which the drawing operation is stopped and the nail print must be redone.

Therefore, it is conceivable to provide a sensor or the like for detecting finger floating in the device, and when the sensor detects finger floating, issue a warning or an error message to alert the user or stop the driving of the drawing head in an emergency. ..
However, the size and shape of fingers vary, and it is difficult for a sensor or the like to reliably detect the floating of a finger in response to the shape of a finger for everyone.
In addition, it is necessary to detect finger floating by following the moving speed of the drawing head and immediately respond to the finger floating, and to make a slight gap between the ink ejection surface of the drawing head and the fingernail. Considering that delicate adjustments are required to detect the float with a sensor, it is difficult to mass-produce the method of detecting and responding to the finger float with a sensor, etc., and the equipment cost will increase. There was a problem.

The present invention has been made in view of the above circumstances, and provides a drawing device capable of safely drawing on a nail by suppressing the floating of a finger during drawing with a simple and inexpensive configuration. Is an advantage.

In order to solve the above problems, the drawing apparatus of the present invention

A finger float suppressing portion arranged on the finger side in the finger resting portion,
When the finger is placed on the finger resting portion or when the placed finger is separated from the finger resting portion, the finger floating suppressing portion is raised to a first position that does not interfere with the finger. At least when drawing by the drawing unit, the finger floating suppressing portion is lowered to a second position where the non-printing finger placed on the finger resting portion comes into contact with at least a part of the finger side.

[Modification example of nail printing device]
Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to such embodiments and can be variously modified without departing from the gist thereof.

For example, in the present embodiment, the head moving unit 49 of the drawing unit 40 is configured to also serve as an elevating mechanism for operating the finger floating suppressing unit 61, but the configuration of the finger floating suppressing mechanism 6 is not limited to this.
For example, as shown in FIGS. 11 and 12, a finger floating suppressing mechanism 9 may be provided separately from the mechanism constituting the drawing unit 40.
In this case, for example, a plate-shaped finger floating suppressing portion 91 which is the front surface portion of the housing 11 of the nail printing device 1 and which is raised and lowered by the raising and lowering motor 92 may be provided on the finger insertion opening 15 into which the finger is inserted. good.
In this case, the finger floating suppressing portion 91 is configured so that it can slide and move along the inner surface of the housing 11 by being guided by a rail or the like (not shown).

Further, in the present embodiment, the locking portion 422 is illustrated as having a convex shape, but the shape of the locking portion 422 is not limited to this.
For example, the locking portion 422 may be formed so that the diameter on the free end side is larger than the diameter of the other portion.
Specifically, as shown in FIG. 13A, the diameter (horizontal direction) of the shaft portion 422a is on the free end side of the locking portion 422 arranged at a position higher than the height (thickness) of the frame body 62. A large diameter portion 422b having a diameter larger than (cross section in the horizontal direction) may be provided.
Further, the shape of the large diameter portion is not limited to that shown in FIG. 13 (a), and may be, for example, a substantially hemispherical large diameter portion 422c as shown in FIG. 13 (b).
By forming the diameter of the locking portion 422 on the free end side larger than the diameter of the other portion in this way, the locking portion 422 can be prevented from coming off from the hook hole portion 621 of the frame body 62.

Further, the locking portion 422 may be provided with a large diameter portion 422d having a size covering a wider range than the frame body 62 (at least the hook hole portion 621 of the frame body 62) on the free end side of the shaft portion 422a. .. In this case, it is possible to reliably prevent the locking portion 422 from coming off from the hook hole portion 621 of the frame body 62.
In this case, after the frame body 62 is installed on the top surface portion 421 on which the shaft portion 422a is formed, the large diameter portion 422d is fitted into the upper end portion of the shaft portion 422a, or the frame body is placed on the top surface portion 421. After installing 62, it is formed by attaching a locking portion 422 in which a large diameter portion 422d and a shaft portion 422a are integrated at a predetermined position in the hook hole portion 621.

Further, the shape of the hook hole portion 621 in the frame body 62 is not limited to that illustrated above.
For example, as shown in FIGS. 14A and 14B, a recess 623 or the like in which the locking portion 422 is locked may be provided on the back side of the hook hole portion 621 in the Y direction.
When the recess 623 is provided, as shown in FIG. 14B, the locking portion 422 is locked in the recess 623, so that the finger float suppressing portion 61 can be pulled up more stably.
As shown in FIG. 14A, the locking portion 422 is not always in the position corresponding to the recess 623 after the drawing operation is completed. Therefore, when pulling up the finger floating suppressing unit 61, the drawing control unit 714 first controls the head moving unit 49 and moves the locking unit 422 in the X direction so as to come to the position corresponding to the recess 623. It is preferable that the position in the X direction is adjusted, and then the drawing head 41 is moved in the Y direction to the outside of the drawable range by the head moving unit 49.

Further, in the present embodiment, as shown in FIG. 7, the index finger of one hand (for example, the left hand) is fixed to the printing finger fixing portion 33 as the printing finger U1, and the other little finger, ring finger, middle finger, and thumb are non-printing fingers U2. As an example, the case where the finger resting portion 30 is placed on the upper surface plate 31 of the finger resting portion 30 and is placed on the side portion of the printing finger fixing portion 33 has been illustrated. It is sufficient that at least a part of the fingers U2 is placed, and not all five fingers of one hand are placed.
For example, when the index finger is the printed finger U1, the little finger, ring finger, and middle finger of the non-printed fingers U2 are placed on the finger resting portion 30, and the thumb is placed below the upper surface plate 31 of the finger resting portion 30. You may. Depending on the type of finger to be printed, the shape of the user's hand, etc., placing all the fingers including the printing finger U1 on the finger resting portion 30 may force an unnatural posture. If it is easier to take a posture when retracted below the face plate 31, the non-printing finger U2 may be arranged as such.
In this case, the finger floating suppressing portion 61 suppresses the floating of the fingers (three fingers, the little finger, the ring finger, and the middle finger in the above example) placed on the upper surface plate 31 of the finger placing portion 30.

Further, in FIG. 7 of the present embodiment, when the drawing head 41 moves into the drawable area and the finger floating suppressing portion 61 is lowered to the second position, the non-printing portion 30 is placed on the finger resting portion 30. Although the figure is shown so that the finger floating suppressing portion 61 abuts on all the fingers U2, the finger floating suppressing portion 61 abuts on at least a part of the fingers placed on the finger resting portion 30. It may be a finger, and may include a finger that the finger floating suppressing portion 61 is not in contact with.
For example, when the little finger, ring finger, middle finger, and thumb are placed as non-printing fingers U2 on the upper surface plate 31 of the finger resting portion 30, the finger floating suppressing portion 61 is placed on the little finger that is thinner than the thumb, middle finger, and the like. May not come into contact. Even in this case, when the user lifts the little finger to the same height position as the thick finger such as the thumb, the position in the height direction is restricted so that the finger lift restraint portion 61 abuts and does not lift any more, which affects drawing. It is possible to avoid the risk of injuring the finger or injuring the finger.

Further, as shown in FIGS. 1 to 4 and the like, a space is provided below the upper surface plate 31 of the finger resting portion 30, and a tray or the like capable of accommodating the finger resting portion 30 may be provided in this space.
When such a tray is provided, when the nail printing device 1 is not used, various tools and accessories used for caring for the nail T are stored in the tray and stored together with the nail printing device 1. It is convenient because it allows you to use the space effectively and keep small items together.

Further, in the present embodiment, the drawing head 41 of the nail printing device (drawing device) 1 is provided with an inkjet drawing head 41, but the configuration of the drawing head 41 is not limited to this.
For example, a pen holder for holding a drawing pen for drawing with a pen tip attached to the surface of the nail T may be provided, and drawing may be performed using the pen. Further, a configuration may be configured in which both an inkjet drawing head and a pen holder for holding a drawing pen as in the present embodiment are provided, and drawing is performed using a plurality of drawing means.

Further, the nail printing device 1 may be provided with a drying portion provided with a heater or a fan for drying the ink after drawing.
