<<First Embodiment>>
<Nail recorder>
The recording apparatus of this embodiment is a nail recording apparatus for recording nail designs on nails. In the following embodiments, it is assumed that the user of the nail recording device is a person who records nail designs on their own nails. Note that the user of the nail recording device and the person to be recorded may be different.

FIG. 1 is a top view showing the outline of the configuration of the nail recording device 20. As shown in FIG. FIG. 2 is a front view showing a schematic configuration of the nail recording device 20. As shown in FIG. FIG. 3 is a right side view showing a schematic configuration of the nail recording device 20. As shown in FIG. FIGS. 1 to 3 show an example of the nail recording device 20 with a housing (not shown) removed. 1 to 3, the +Y direction is the front side, the -Y direction is the back side (rear side), the +X direction is the right side, the -X direction is the left side, the +Z direction is the bottom side, and the -Z direction is the top side. The Z-axis corresponds to the direction of gravity.

The nail recording device 20 is configured to record a nail design by ejecting ink (liquid) onto a nail, which is a recording medium, by an inkjet method. A nail finger to be recorded is called a printing finger. The nail recording device 20 includes a recording unit 203 that records the nail, and a hand placement unit 205 that can move the nail relative to the recording unit 203 in the Z direction. In other words, the hand rest portion 205 is configured to be able to move up and down with the printing finger resting thereon. The nail recording device 20 also has an imaging unit 204 that captures an image of the printing finger from above and recognizes the position of the nail in the XY directions. The overall operation of the nail recording device 20 is controlled by a control section 40 (see FIG. 4).

<Recording unit>
The recording unit 203 has a carriage 2031 on which a recording head 2030 is mounted. The recording head 2030 has the following ink ejection nozzles.
・Nozzle 2032 for ejecting cyan ink
・Magenta ink discharge nozzle 2033
・Yellow ink discharge nozzle 2034
The recording head 2030 ejects ink supplied from an ink tank (not shown) attached to the carriage 2031 using the ink ejection nozzles described above.

The carriage 2031 and the recording head 2030 mounted on the carriage 2031 are provided so as to be relatively movable in at least the XY directions with respect to a hand rest section 205, which will be described later. A specific description will be given. The nail recording device 20 includes Y-direction rail guides 2011 and 2012 and an X-direction rail guide 2020 . Y-direction rail guides 2011 and 2012 extend in the Y-direction and are used to move the carriage 2031 forward and backward. The X-direction rail guide 2020 extends in the X-direction that intersects (perpendicularly in this embodiment) the Y-direction, and is used to move the carriage 2031 in the left-right direction. The carriage 2031 and the recording head 2030 can move in the XY directions along the Y-direction rail guides 2011 and 2012 and the X-direction rail guide 2020 by using two motors (not shown).

When performing printing, the printing unit 203 performs a printing operation of printing an image for one scan by ejecting ink while moving the print head 2030 in the X direction with respect to a nail, which is a printing medium. Thereafter, after performing a movement operation for moving the recording head 2030 by a predetermined amount in the Y direction, the recording operation is performed again. In this manner, the nail recording device 20 alternately and repeatedly executes the recording operation and the moving operation to record an image on the nail. In this manner, the position of the nail, which is the recording medium (recording target) in the nail recording apparatus 20, is not moved during recording, and recording is performed on the nail while the recording unit 203 changes the position in the XY direction with respect to the recording medium. will be done.

<Shooting department>
The photographing unit 204 includes a camera 2040 installed inside the ceiling of the nail recording device 20 for photographing the finger. A photographing lens 2041 is arranged below the camera 2040 . The photographing unit 204 may be installed in the nail recording device 20, or may be separately attached by the user, for example, a smartphone with a camera function. By capturing an image from the imaging unit 204 while the hand is placed on the hand placing unit 205, the general position of the nail, which is a recording medium, can be specified.

<Hand rest>
The hand rest portion 205 includes a palm rest portion 2050 for placing the palm and printing finger fixing portions 2110 and 2120 for fixing the fingers, which are arranged on the bottom side (lower side) of the nail recording device 20 . , 2130, 2140. The hand rest 205 can be pulled out from the nail recording device 20 toward the front side (+Y direction side), or can be pushed into the nail recording device 20 (−Y direction side) from the pulled out state. . The user pulls out the hand rest portion 205 from the nail recording device 20 toward the front side (+Y direction side), and places the hand on the pulled out hand rest portion 205 . At this time, as will be described later, the user performs an operation of aligning the position of the finger on the printing finger fixing portion. After that, the user pushes the hand rest portion 205 into the nail recording device 20 while placing the printing finger on the hand rest portion 205, and the printing finger fixing portion rises, so that the recording portion 203 can perform recording. A claw portion, which is a recording medium, can be positioned in the recording area.

FIGS. 1 to 3 also schematically show an example in which the user's hand and fingers are inserted into the nail recording device 20. FIG. Specifically, an example in which the user's right hand 30 is placed on the hand placing portion 205 is shown. The palm 300 of the right hand 30 is placed on the palm placing section 2050 . A right index finger 301, a right middle finger 302, a right ring finger 303, and a right little finger 304 are placed on printing finger fixing portions 2110, 2120, 2130, and 2140, respectively. Details of the finger fixing portion will be described later.

As described above, the hand rest section 205 of this embodiment is provided with the printing finger fixing sections 2110, 2120, 2130, and 2140 corresponding to the four fingers. When the user wishes to record the thumb nail of the right hand 30 , the user places the right thumb (not shown) on the printing finger fixing section 2140 . On the other hand, when it is desired to record the nails of the left hand, the left index finger, the left middle finger, the left ring finger, and the left little finger are placed on the printing finger fixing units 2140, 2130, 2120, and 2110, respectively, contrary to the case of the right hand. will be Also, when the user wishes to record the left thumb, the user places the left thumb on the printing finger fixing unit 2110 . Note that the thumbs of both hands may be placed on the printing finger fixing portions 2110 and 2140, respectively. As described above, even for a single user, the finger to be placed may change, so the length of the printing finger placed on the printing finger fixing portion may change. Also, the length of the finger differs from user to user. In this way, the present embodiment is configured to allow an image (nail design) to be accurately recorded on the nail even if the finger length differs for each user and for each finger. ing.

In this embodiment, an example in which printing finger fixing portions corresponding to four fingers are provided is shown, but any printing finger fixing portion corresponding to one or more fingers may be provided. By providing printing finger fixing portions corresponding to a plurality of fingers as in the present embodiment, it is possible to collectively record nail designs on a plurality of nails.

<Printing finger fixing part>
FIG. 5 is a top view showing a schematic configuration of the hand rest section 205. As shown in FIG. FIG. 6 is a cross-sectional view showing an outline of the printing finger fixing portion 2110. As shown in FIG. The configuration of the printing finger fixing unit will be described with reference to FIGS. 5 and 6. FIG. As shown in FIG. 5, the hand rest section 205 includes four printing finger fixing sections 2110, 2120, 2130, and 2140 corresponding to four fingers. That is, the hand rest portion 205 is provided with a plurality of printing finger fixing portions. The following description focuses on the printing finger fixing unit 2110. FIG. Other printing finger fixing units 2120, 2130, and 2140 also have similar configurations.

The printing finger fixing portion 2110 is a portion for fixing the finger 301 (in this example, the right index finger 301, but for the sake of simplicity, simply referred to as “finger”). The printing finger fixing unit 2110 includes a finger pressing member 2111 that covers at least a portion of the finger 301 excluding the claw portion, an abutting member 2112 against which the vicinity of the tip of the finger 301 abuts, and a finger placing portion 2114 for placing the finger. have. As described above, the hand rest portion 205 including the printing finger fixing portion 2110 and the palm rest portion 2050 can be pulled out from the nail recording apparatus 20 toward the front side (+Y direction side), and can be used for nail recording from the pulled out state. It can be pushed into the device 20 (-Y direction side). That is, the printing finger fixing portion 2110 and the palm placing portion 2050 can move to the front side and the back side of the nail recording device 20 together.

A motor (not shown) is provided inside the finger placing portion 2114 and has a mechanism for moving the finger placing portion 2114 up and down. It should be noted that it is not always necessary to use a motor to raise and lower the finger rest portion 2114, and for example, it may be raised and lowered by an urging member such as a spring. When printing on the nail, it is required to arrange the nail at a fixed position from the print head 2030 . This is because if the distance from the ejection nozzles of the recording head 2030 to the claw, which is the recording medium, is greater than a predetermined distance, the printing accuracy may not be improved. Therefore, when recording is performed, the finger rest section 2114 is raised to a certain position by a motor (not shown) or the like.

The abutment member 2112 is a member provided at a position where the vicinity of the tip of the finger 301 abuts. In this embodiment, the finger 301 is aligned with the printing finger fixing portion 2110 . The abutting member 2112 is a member used for this finger alignment. It should be noted that when recording on a fingernail, the fingernail must be exposed. On the other hand, as described above, printing is performed with the print head 2030 in close proximity to the fingernail, so it is required to suppress unexpected actions by the user. A finger pressing member 2111 is provided above the finger placing portion 2114 (on the −Z direction side) in order to suppress such an unexpected movement of the user. An opening is formed between the abutting member 2112 and the finger pressing member 2111 when viewed from the recording head 2030 (above). The print head 2030 prints on the nail exposed in this opening. Therefore, positioning of the finger 301 and the printing finger fixing portion 2110 is performed in order to position the opening portion (claw portion), which may differ depending on the length of the finger.

In this embodiment, as shown in FIG. 6, the abutting member 2112 has a structure capable of abutting against the tip of the pad of the finger. That is, the abutment member 2112 is positioned upward (-Z direction) so as to restrict the movement of the finger 301 in the insertion direction at a position on the end side of the printing finger fixing portion 2110 in the finger insertion direction (-Y direction). ). Further, the abutting member 2112 is provided in a shape protruding to a position lower than at least the position where the finger pressing member 2111 is provided. In general, a base or the like is sometimes applied to the nail before recording on the nail. By using such an abutting member 2112, when the finger 301 is inserted into the printing finger fixing portion 2110, the finger 301 can be abutted without damaging the coated portion of the nail on which the base or the like is applied. In addition, since the abutment member 2112 can abut against the tip of the pad of the finger, it is possible to suppress the inability to record up to the edge of the nail due to the abutment of the nail against the abutment member 2112 . . In this manner, the user inserts the finger into the printing finger fixing portion 2110 and places the finger on the finger placing portion 2114 and the abutting member 2112 . The print finger fixing portion is also called a finger insertion portion. Note that the finger placing portion 2114 and the abutment member 2112 may be integrally configured members, or may be separate members.

In FIG. 6, the shape of the position of the abutment member 2112 with which the finger abuts is schematically illustrated as a right-angled shape, but it may be a curved shape. Also, the vicinity area of the abutting member 2112 with which the finger abuts may be configured to be inclined (upwardly) at a predetermined angle from the horizontal direction.

In this embodiment, the abutting member 2112 is attached so as to be slidable in the printing finger insertion direction (-Y direction). Then, the printing finger fixing portion 2110 slides in conjunction with the sliding of the abutting member 2112 . That is, the finger placing portion 2114 slides in conjunction with the sliding of the abutting member 2112 . The printing finger fixing portion 2110 is configured to be slidable in both a finger insertion direction (−Y direction) and a direction opposite to the finger insertion direction (+Y direction). The printing finger fixing unit 2110 also includes a biasing member 2113 . The printing finger fixing portion 2110 is biased by a biasing member 2113 in a direction (+Y direction) opposite to the insertion direction of the finger 301 . In other words, the printing finger fixing portion 2110 is biased toward the palm rest portion 2050 . According to such a configuration, the printing finger fixing portion 2110 returns to the front position (+Y direction) when the finger 301 is pulled out. In other words, the printing finger fixing unit 2110 returns to the initial position. In this state, if the left hand is inserted instead of the right hand, another finger is inserted, or another user's hand is inserted and the finger is inserted, the printing finger fixing unit 2110 again Slide in the Y direction. Then, the printing finger is positioned with respect to the printing finger fixing portion 2110 . Note that the printing finger fixing portion 2110 of the present embodiment will be described with an example in which the finger placement portion 2114 slides in conjunction with the sliding of the abutting member 2112, but the present invention is not limited to this. When the abutment member 2112 slides, the finger placement section 2114 does not need to slide in conjunction with it. Further, the printing finger fixing unit 2110 of the present embodiment will be described with an example in which the finger pressing member 2111 slides in conjunction with the sliding of the abutment member 2112, but the present invention is not limited to this example. When the abutting member 2112 slides, the finger pressing member 2111 does not need to slide in conjunction with it.

As shown in FIG. 6, the printing finger fixing section 2110 of this embodiment includes a fixing member 2116 for fixing the slide position. The fixing member 2116 has a switching mechanism 2115 and a stopper portion 2117 for switching between fixing and non-fixing. When the user pushes the switching mechanism 2115 downward, the stopper portion 2117 comes into contact with the friction member 2118 . As a result, the sliding position of the printing finger fixing portion 2110 can be fixed by applying a frictional force to the fixing member 2116 . It is assumed that the switching by the switching mechanism 2115 is performed with the hand rest portion 205 pulled out from the nail recording device 20, but the present invention is not limited to this. Switching by the switching mechanism 2115 may be performed while the hand rest portion 205 is pushed into the nail recording device 20 .

Any member can be used as the friction member 2118 . For example, a non-slip friction member 2118 having unevenness or the like may be used. Also, the friction member 2118 may be provided with a concave portion that engages with the convex portion of the stopper portion 2117 . In addition, any member can be used as long as the movement of the printing finger fixing portion 2110 is restricted by the fixing member 2116 . In this manner, the fixing member 2116 allows the finger 301 to remain positioned on the printing finger fixing portion 2110 . Therefore, even when the finger 301 is lifted by the lifting of the finger rest portion 2114 and positioned in the recording area, the position and orientation of the claw portion, which is the recording medium, can be maintained.

Further, when the user further pushes the switching mechanism 2115 in a state where the slide position of the printing finger fixing portion 2110 is fixed, the fixing member 2116 is pushed upward and fixed is released. Therefore, by operating the switching mechanism 2115, the user can freely operate the fixation and release of the fixation by the fixing member 2116 by himself/herself. That is, by operating the switching mechanism 2115, the user can fix the slide position to an arbitrary position or release the fixation. That is, the sliding position of the printing finger fixing unit 2110 can be fixed at any position in the finger insertion direction (−Y direction) and in the direction opposite to the insertion direction (+Y direction). Therefore, it is possible for the user to fine-tune the position of the finger by himself/herself. In this manner, the switching mechanism 2115 functions as an operation unit that receives a user's operation for switching between presence and absence of slide.

Note that the switching mechanism 2115 may also have a knob shape for performing a sliding operation of the printing finger fixing portion 2110 . That is, the switching mechanism 2115 may also serve as an operation unit that receives a user's slide operation. In this case, after placing the printing finger on the printing finger fixing unit 2110, if the user wants to adjust the slide position of the printing finger, the switching mechanism 2115 is partially pinched or pressed to slide. Position changes can be made. Note that the switching method of the switching mechanism 2115 is not limited to the above configuration. For example, the switching mechanism 2115 may be a seesaw switch, and when the switch is turned on, the stopper portion 2117 may be lowered to come into contact with the friction member 2118 .

Although the printing finger fixing unit 2110 has been described above as an example, other printing finger fixing units are the same. That is, the printing finger fixing unit 2120 includes a switching mechanism 2125 for switching fixing by the fixing member 2126 for fixing the slide position. The printing finger fixing unit 2130 includes a switching mechanism 2135 for switching fixing by a fixing member 2136 for fixing the sliding position. The printing finger fixing unit 2140 includes a switching mechanism 2145 for switching fixing by a fixing member 2146 for fixing the slide position.

The printing finger fixing unit 2120 also includes a biasing member 2123 that biases the printing finger 302 in the opposite direction (+Y direction) to the insertion direction of the finger 302 . The printing finger fixing unit 2130 includes a biasing member 2133 and is biased by the biasing member 2133 in a direction (+Y direction) opposite to the insertion direction of the finger 303 . The printing finger fixing unit 2140 includes a biasing member 2143 and is biased by the biasing member 2143 in a direction (+Y direction) opposite to the insertion direction of the finger 304 . 5 and 6 show an example in which the biasing member is provided on the side opposite to the palm resting portion 2050, but the biasing member is provided on the palm resting portion 2050 side. good too.

In this manner, the printing finger fixing units 2110, 2120, 2130, and 2140 are configured to be slidable independently. Further, each printing finger fixing portion can independently fix the slide position. Therefore, it is possible to finely adjust the positions of other fingers while a specific finger is fixed. Also, although the number of printing finger fixing portions has been described as four, the present invention is not limited to four. Also, an example is shown in which the switching mechanism is configured integrally with the fixing member and arranged on the finger insertion direction side (-Y direction side) from the abutting member of each printing finger fixing portion. Not limited. The switching mechanism may be configured integrally with the finger pressing member, and may be configured such that pressing down the finger pressing member causes the fixed member to be pressed down in conjunction with the depression of the finger pressing member.

As described above, in this embodiment, when the user inserts the finger 302 , the printing finger fixing unit 2110 slides according to the insertion of the finger 302 . In this embodiment, a fixing member 2116 is provided in the printing finger fixing unit 2110 , and fixing and releasing by the fixing member 2116 can be switched by a switching mechanism 2115 . Therefore, the position of the printing finger fixing portion 2110 can be fixed at an arbitrary position, improving usability. That is, it becomes possible to adjust the finger to any position. In addition, it is possible to fix the position of the printing finger fixing part of each finger at an arbitrary position. It is possible.

<<Second Embodiment>>
In the nail recording device of the first embodiment, an example has been described in which each of the printing finger fixing units is provided with a switching mechanism, and the slide fixing of each printing finger fixing unit can be performed individually. In the nail recording apparatus of the present embodiment, an example will be described in which the slide fixation of each printing finger fixing portion can be switched collectively by a switching mechanism.

In this embodiment, printing finger fixing units 2110, 2120, 2130, and 2140 are different from the nail recording apparatus in the first embodiment, so the differences will be described in detail below, and description of other common parts will be omitted.

FIG. 7 is a top view showing a schematic configuration of the hand rest section 205 of this embodiment. FIG. 8 is a cross-sectional view showing an outline of the printing finger fixing portion 2110 of this embodiment. In this embodiment, the switching mechanism 2150 is provided in the palm rest section 2050 instead of in each printing finger fixing section. Also, the switching mechanism 2150 of this embodiment is connected to the fixing member of each printing finger fixing unit. By pushing down the switching mechanism 2150, the fixing members of the printing finger fixing portions are fixed collectively. In addition, by further pushing up the switching mechanism 2150 in this state, the fixing by the fixing member of each printing finger fixing portion is released collectively.

As described above, in this embodiment, the switching mechanism 2150 can collectively fix and release the fixing members of the printing finger fixing portions. Therefore, usability is improved. In addition, in this embodiment, the switching mechanism 2150 is provided in the palm resting part 2050, and the fixing member is fixed via the switching mechanism 2150 with the palm resting. Therefore, as a user's operation, the slide position can be fixed by placing the palm on the palm placing portion 2050 after inserting the finger into the printing finger fixing portion and positioning the finger.

In the present embodiment, an example in which the switching mechanism 2150 for collectively fixing and releasing the sliding of the printing finger fixing units is provided in the palm rest unit 2050 has been described, but the present invention is not limited to this. As described in the first embodiment, each printing finger fixing unit may be provided with a switching mechanism. However, each switching mechanism in this example does not operate independently, and the fixing and release of the slide of each printing finger fixing portion are collectively performed in conjunction with the switching control of any switching mechanism. Thus, the switching mechanism 2150 may be provided at any position.

As described above, also in this embodiment, it is possible to improve the usability when fixing the slide of the printing finger fixing portion.

<<Third Embodiment>>
In the nail recording device of the first embodiment, an example has been described in which each printing finger fixing portion is provided with a switching mechanism for switching between fixation and release of the sliding of the printing finger fixing portion. In the second embodiment, an example in which a switching mechanism for switching between fixing and releasing the sliding of the printing finger fixing unit is provided in the palm rest unit 2050 has been described. In this embodiment, an example in which the switching mechanism is provided at a position different from the hand rest portion 205 will be described. In this embodiment, printing finger fixing units 2110, 2120, 2130, and 2140 are different from the nail recording apparatus in the first embodiment, so the differences will be described in detail below, and description of other common parts will be omitted.
