Japanese Patent Publication No. 2009-543246

A plurality of selectable images are usually displayed on the operation screen of the non-contact type input device. With such a non-contact input device, it is difficult for the user to intuitively determine the position where the image is selected. In addition, since the user does not touch the operation screen directly with the non-contact input device, erroneous image selection (erroneous operation) is more likely to occur than with the contact-type input device.

The present disclosure has been made in view of the above problems, and an object thereof is to provide an input device that allows a user to easily select an image intended by the user without contact, and a medical device equipped with the input device. That's what it is.

According to one aspect of the present disclosure, an input device includes a display device that displays an operation screen, a sensor that detects a non-contact operation on the operation screen by a pointer, and a first opening and a first opening at positions facing the operation screen. a frame having two openings. A pointer can be inserted into the first opening and the second opening. The operation screen includes a first image and a second image, each of which can be operated. The first opening and the first image at least partially overlap each other when the operation screen is viewed from the front. The second opening and the second image are at least partially overlapped when the operation screen is viewed from the front.

According to the above disclosure, it is possible to easily select an image intended by the user without contact.

1 is a front view of a medical device; FIG. 1 is a perspective view of an input device; FIG. 1 is an exploded perspective view of an input device; FIG. It is the figure which showed the input device when the operation screen is viewed from the front.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following description, the same members are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. Moreover, in the embodiments described below, when referring to the number, amount, etc., the scope of the present invention is not necessarily limited to the number, amount, etc., unless otherwise specified.

FIG. 1 is a front view of the medical device 1. FIG. As shown in FIG. 1, the medical device 1 includes an input device 10 and a main body device 20. As shown in FIG. In this example, the medical device 1 is a dialysis machine.

The input device 10 is a non-contact input device. The input device 10 displays an operation screen. The input device 10 is installed above the main device 20 . The input device 10 is communicably connected to the main device 20 .

Main unit 20 performs artificial dialysis. The main device 20 operates based on instructions input by the input device 10 . A medical device using the input device 10 is not limited to a dialysis machine. Further, the equipment using the input device 10 is not limited to medical equipment, and may be other equipment.

FIG. 2 is a perspective view of the input device 10. FIG. As shown in FIG. 2 , the input device 10 includes a main body portion 1000 and an outer frame (frame body) 300 . Main body 1000 includes display panel (display device) 100 , inner frame 200 , and line sensor 400 .

Display panel 100 is typically a display. The display panel 100 may be a touch screen in which a touch panel is combined with a display (that is, a display with a touch panel).

The outer frame 300 includes an opening 310 and openings 320-331. In this example, opening 310 is larger than openings 320-331. The openings 320-331 are provided in a matrix. Fingers and pointers such as stylus pens can be inserted into openings 320-331. The example of FIG. 2 shows a state in which a finger is inserted into the opening 324 .

FIG. 3 is an exploded perspective view of the input device 10. FIG. As also shown in FIG. 3 , the input device 10 includes a display panel 100 , an inner frame 200 , an outer frame 300 and a line sensor 400 .

The display panel 100 has a bezel 110 and a display area 120 . The display area 120 is parallel to the XZ plane. The bezel 110 has a front portion 111 parallel to the display area 120 and side portions 112 perpendicular to the display area 120 .

The display panel 100 displays a predetermined operation screen G in the display area 120 . The operation screen G includes an inoperable image 130 and ten images (object images) 140 to 149, each of which can be operated. In this example, the image 130 represents the value of the set flow rate as an example of the display data. Images 140-149 each show one digit from 0-9. Specifically, the processor (not shown) of the input device 10 causes the display panel 100 to display the operation screen G. FIG.

Outer frame 300 includes opening 310 and openings 320-331, as described above. The outer frame 300 further comprises an inner surface 350. As shown in FIG. Opening 310 and openings 320-331 are parallel to the XZ plane. The opening 310 and the openings 320 to 331 are provided at positions facing the operation screen G. As shown in FIG.

The inner frame 200 is attached to the bezel 110 of the display panel 100 in this example. Specifically, the inner frame 200 is attached to the front portion 111 of the bezel 110 . How to attach the inner frame 200 is not particularly limited. Inner frame 200 may be attached to bezel 110 by adhesive or the like.

The inner frame 200 has four inner sides 211-214 and four outer sides 221-224. The inner surface 211 is the bottom surface. The inner side surface 211 is a surface parallel to the XY plane and in the Z-axis negative direction. The inner surface 212 is the upper surface. The inner side surface 212 is a surface parallel to the XY plane and in the Z-axis positive direction. The inner surface 212 faces the inner surface 211 . The inner surfaces 213, 214 are sides. The inner side surfaces 213 and 214 are surfaces parallel to the YZ plane. The inner side 213 faces the inner side 214 .

The inner frame 200 is housed inside the outer frame 300 . Specifically, the outer frame 300 is fitted into the inner frame 200 so that the outer side surfaces 221 to 224 of the inner frame 200 are in contact with the inner side surface 350 of the outer frame 300 .

The line sensor 400 is an infrared spatial position sensor in this example. The line sensor 400 is provided on the operation screen G side with respect to the openings 310, 320 to 331 when the operation screen G is viewed from the front (Y-axis positive direction). The line sensor 400 is installed on the inner surface 211 of the inner frame 200 . The line sensor 400 is installed at the end of the inner surface 211 on the Y-axis negative direction side. In the line sensor 400, a plurality of sensors are arranged side by side along the X-axis direction.

The line sensor 400 irradiates a plurality of infrared rays in the direction from the inner surface 211 to the inner surface 212 (the Z-axis positive direction) as indicated by arrow A. The line sensor 400 receives reflected infrared light. The input device 10 can determine the position of the pointer on the XZ plane by reflecting the infrared rays from the pointer such as the finger. This allows the input device 10 to determine, for example, which of the images 140 to 149 has been selected by the pointer. For example, in the example of FIG. 2, when line sensor 400 detects an operation of selecting image 144 with a finger, input device 10 accepts input of the number "4".

The line sensor 400 may be a ToF (Time of Flight) range image sensor.

FIG. 4 is a diagram showing the input device 10 when the operation screen G is viewed from the front. As shown in FIG. 4 , when the operation screen G is viewed from the front, a portion (center) of the image 130 overlaps the opening 310 . When the operation screen G is viewed from the front, the entire (whole) image 140 representing the number 0 overlaps with a portion (central portion) of the opening 320 . When the operation screen G is viewed from the front, the entire image 141 representing the numeral 1 overlaps with a portion (central portion) of the opening 321 . Similarly, when the operation screen G is viewed from the front, all of the images 142 to 149 overlap with portions (central portions) of the corresponding openings 322 to 329 .

The sizes of the openings 320 to 329 (the lengths of the openings in the vertical and horizontal directions) are defined by the sizes of the images 140 to 149 (lengths in the vertical direction (Z direction) and the horizontal direction (X direction)). . From the viewpoint of operability, it is preferable that the sizes of the openings 320 to 329 are substantially the same as the sizes of the corresponding images 140 to 149 . However, the size of the openings 320-329 is not limited to this, and the sizes of the corresponding images 140-149 may be smaller or larger. Also, the size of the opening 310 is defined by the size of the image 130 .

The manner in which the opening and the image overlap is not limited to the above mode. At least, it is sufficient that the opening and the image are overlapped as described below. It is sufficient that the opening 320 and the image 140 at least partially overlap each other when the operation screen G is viewed from the front. It is sufficient that the opening 321 and the image 141 at least partially overlap each other when the operation screen G is viewed from the front. Similarly, the openings 322 to 329 and the images 142 to 149 corresponding to the openings 322 to 329 may at least partially overlap when the operation screen G is viewed from the front. It is sufficient that the opening 310 and the image 130 representing the value of the set flow rate overlap at least partially when the operation screen G is viewed from the front.

(Brief Summary)
(1) As described above, the input device 10 includes the display panel 100 that displays the operation screen G, the line sensor 400 that detects a non-contact operation on the operation screen G by an indicator such as a finger, and the operation screen G. and an outer frame 300 having openings 310, 320 to 329 at positions corresponding to the openings. Each opening 310, 320-329 is capable of inserting an indicator such as a finger. The operation screen G includes images 140 to 149, each of which can be operated.

The openings 310, 320 to 329 and the images 130 and 140 to 140 overlap each other at least partially when the operation screen G is viewed from the front. For example, the opening 320 and the image 140 at least partially overlap when the operation screen G is viewed from the front. The opening 321 and the image 141 are at least partially overlapped when the operation screen G is viewed from the front.

According to such a configuration, if the user of the input device 10 inserts the pointer into the openings 310, 320 to 329, the image corresponding to the openings 310, 320 to 329 into which the pointer is inserted can be displayed in a non-contact manner. can be selected.

Therefore, according to the input device 10, the user can intuitively determine the position where the object is selected (the detection area of the line sensor 400). In addition, since the openings 310 and 320 to 329 are provided, erroneous image selection (erroneous operation) is less likely to occur than in a configuration without the outer frame 300 . Therefore, according to the input device 10, the image intended by the user can be easily selected in a non-contact manner.

Further, in the input device 10, it is not necessary to increase the distance between the images 140-149 in order to avoid the user's erroneous operation (erroneous selection) on the images 140-149. As a result, there is no need to reduce the number of images that can be included in the operation screen G compared to a contact-type input device.

In the medical device 1, the size of the display panel 100 is restricted. Therefore, by providing the input device 10 in the medical device 1, the area of the display panel can be effectively utilized. In particular, the size of the display panel 100 is limited in a device such as the medical device 1 shown in FIG. 1 that can be moved by casters or the like. Therefore, the input device 10 is preferably used for such mobile medical equipment 1 .

(2) The line sensor 400 is provided on the operation screen G side with respect to the openings 310, 320 to 329 when the operation screen G is viewed from the front. According to such a configuration, the input device 10 accepts an input by inserting a pointer into the openings 320-329.

(3) The operation screen G further includes an inoperable image 130 . The outer frame 300 further has an opening 310 at a position facing the operation screen G. As shown in FIG. The opening 310 and the image 130 are at least partially overlapped when the operation screen G is viewed from the front. With such a configuration, the user can visually recognize the image 130 through the opening 310 .

(4) opening 310 is larger than openings 320-331; With such a configuration, the user can visually recognize more information through the opening 310 than each of the openings 320 to 331 .

(5) Images 140-149 each represent one of the numbers 0-9. When any one image is operated, the input device 10 accepts input of numbers associated with the image. For example, the input device 10 accepts an input of "1" when the image 141 is operated, and accepts an input of "2" when the image 142 is operated. According to such a configuration, the user can easily input the intended number in a non-contact manner.

(6) Further advantages of the input device 10 are as follows. For example, when a plurality of predetermined numbers are operated in a predetermined order (for example, "1" → "2" → "3" operation), a specific action (for example, medical device 1 or input device 10), the medical device 1 or the input device 10 is configured.

In a conventional configuration that does not have the outer frame 300, when the finger moves parallel to the operation screen (when the finger crosses over the image of the number), each number may not be detected correctly. . On the other hand, according to the input device 10 of the present embodiment, it is possible to accurately distinguish and judge operation input of each number. Therefore, according to the input device 10, it is possible to cause the input device 10 or the medical device 1 to perform the operation intended by the user.

<Modification>
(1) The bezel 110 and the inner frame 200 may be integrally formed.

(2) The display panel 100 may be inserted into the inner frame 200 . Specifically, the input device 10 is configured so that the side surface portion 112 of the bezel 110 of the display panel 100 is in contact with the inner side surfaces 211 to 214 at the ends of the inner side surfaces 211 to 214 of the inner frame 200 in the positive Y-axis direction. good too.

(3) In the above, the outer frame 300 is fitted onto the inner frame 200 as described above. However, without being limited to this, the input device 10 may be configured such that the outer frame 300 is internally fitted to the inner frame 200 .

(4) In the above, the case where the display panel 100 displays the operation screen G including the image 130 and the images 140 to 149 such as numbers has been described as an example, but the present invention is not limited to this. The display panel 100 can display various operation screens. Further, in the input device 10, an outer frame having an opening pattern corresponding to the arrangement of images included in the operation screen is configured to be attachable to and detachable from the main body portion 1000. FIG. By making the outer frame detachable from the main body 1000 in this way, the input device 10 with excellent versatility can be obtained.

(5) In the above description, the display as the display panel 100 and the line sensor 400 are used to detect the image selection operation by the pointer. However, it is not limited to this. By using the display panel 100 as a capacitive touch screen, the line sensor 400 becomes unnecessary. In other words, the line sensor 400 becomes unnecessary by adopting a system in which the display panel 100 incorporates the capacitance type sensor. In this case, a capacitive sensor detects a non-contact operation on the operation screen G by an indicator such as a finger.

(6) Instead of the display panel 100 , the input device 10 may have a display device (aerial display) that displays an aerial image on the display panel 100 . Specifically, the input device 10 includes a display device including a display panel (typically a liquid crystal display) and an image forming plate for forming an image displayed on the display panel in the air. good too.

In this case, an image formed in the air (aerial image) corresponds to the operation screen. Since the operation screen is an aerial image, there is no physical contact with the operation screen. Also in this configuration, it is not necessary to make contact with the display panel.

(7) The inner frame 200 is not necessarily required. In this case, the outer frame 300 may be attached to the display panel 100 and the line sensor 400 may be installed on the outer frame 300 .

(8) In the above description, the numeric keypad (operating keys 0, 1 to 9) has been described as an example of an operable image. However, the operable image is not limited to the numeric keypad. The image is not particularly limited as long as it is a selectable image. For example, the image may be an up key, a down key, or the like.

It should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The patent scope of the present disclosure is indicated by the scope of claims, and is intended to include all modifications within the meaning and scope of equivalence to the scope of the claims.
