[0011] [First embodiment] Hereinafter, an embodiment of one aspect of the present invention (hereinafter also referred to as “this embodiment”) will be described based on the drawings. In addition, the same reference numerals are attached to the same or corresponding parts in the drawings, and their description will not be repeated.

[0012] (Configuration of Sensing Device 1) Figure 1 It is a front view of the sensing device 1 according to the first embodiment. Figure 2 It is a rear view of the sensing device 1 according to the first embodiment. Figure 3 1 is a side view of the sensing device 1 according to the first embodiment. Figure 1 to Figure 3 The up-down direction corresponds to the up-down direction of the sensing device 1 .

[0013] The sensing device 1 is a portable device that measures the state quantity of an object such as temperature in a non-contact manner and displays the measurement result on a display screen. The sensing device 1 includes a main body 2, a protruding portion 3, a first sensor 4 (sensor), and a second sensor 5. The second sensor 5 may not be present. The main body 2 accommodates various electronic devices that function as the sensing device 1. The main body 2 is a plate-like member having a substantially rectangular front surface 28 and a back surface 22, side surfaces 24, 24, an upper surface 26, and a lower surface 27. The side surfaces 24, 24 are rounded.

[0014] The main body 2 has a display screen 21 on the front surface 28. The display screen 21 displays various information such as the measurement results of the first sensor 4 and the second sensor 5.

[0015] The protrusion 3 is a shape that protrudes from the back surface 22 of the main body 2 that is opposite to the display screen 21, and extends in parallel with the side 22a that intersects the back surface 22 and the upper surface 26 in the main body 2. The length of the extension is substantially equal to the width in the extension direction of the back surface 22 of the main body 2. The operator's hand can hold the side surface 31 of the extended protrusion 3. The protrusion length of the protrusion 3 from the main body 2 is preferably greater than the thickness of a general operator's finger.

[0016] The first sensor 4 is a sensor provided on the protrusion 3. The first sensor 4 is located at the center of the protrusion 3, but is not limited to this position. That is, the first sensor 4 can also be arranged at any position of the protrusion 3. The first sensor 4 can be an infrared sensor, a camera, a Lidar (Light detection and ranging) sensor, or a Radar (Radio detection and ranging) sensor. That is, the first sensor 4 is a sensor that measures the state quantity of the object in a non-contact manner.

[0017] The second sensor 5 is a sensor provided on the main body 2. The second sensor 5 may be an infrared sensor, a camera, a lidar sensor, or a radar sensor. Furthermore, the second sensor 5 may also be a sensor that measures a state quantity different from that of the first sensor 4 in a non-contact manner. In this case, two or more state quantities may be measured at one time. Furthermore, a lamp may be provided instead of the second sensor 5.

[0018] (Retention of protrusion 3) Figure 4 1 is a rear view showing a certain holding method of the sensing device 1. Figure 4 As shown, the operator's thumb 63 is placed on the front surface 28 of the sensing device 1 (refer to Figure 6), the operator places the remaining fingers of the operator on the back surface 22 of the sensing device 1. Thus, the operator can clamp the front surface 28 and the back surface 22 of the sensing device 1 with the hand 6.

[0019] Furthermore, if Figure 4 As shown, by the index finger 61 of the operator's hand 6 contacting the lower side surface 31 of the protrusion 3, the sensing device 1 can be prevented from falling off from the operator's hand 6 in the direction from the upper surface 26 to the lower surface 27 of the main body 2.

[0020] Figure 5 2 is a rear view showing another method of holding the sensing device 1. Figure 4 Compared with the situation in Figure 5 In the case of the operator's hand 6, the index finger 61 of the operator's hand 6 contacts the upper side surface 31 of the protrusion 3, and the middle finger 62 of the operator's hand 6 contacts the lower side surface 31 of the protrusion 3, and the rest is the same. By pinching the protrusion 3 with the index finger 61 and the middle finger 62, the sensing device 1 can be reliably held.

[0021] exist Figure 5 In order to hold the sensing device 1, the index finger 61 and the middle finger 62 are used, but not limited thereto, and the middle finger and the ring finger, or the ring finger and the little finger may also be used.

[0022] Since the first sensor is disposed on the protruding portion 3, the object can be measured without being blocked by the operator's finger. Furthermore, since it is non-contact, the object can be measured efficiently.

[0023] (recess 23) Figure 6 yes Figure 4 A concave portion 23 is formed on the front surface of the main body 2 between the display screen 21 and the side surface 24. Therefore, the direction in which the concave portion 23 extends is orthogonal to the direction in which the protrusion 3 extends.

[0024] The side surface 24 forms a convex curved surface along the first interdigital gap between the thumb 63 and the index finger 61. A ridge line 25 is formed at the intersection of the side surface 24 and the concave portion 23. As a result, Figure 6 The outer shape of the cross section of the main body portion 2 shown in the figure has an inflection point at the ridge line 25 and changes into a concave-convex shape.

[0025] By placing the fingertips of the thumb 63 of the hand 6 in the recess 23 and the other fingers on the back surface 22 of the main body 2, the front and back surfaces of the sensor device 1 can be gripped. Therefore, there is no need to grip the sides by twisting the wrist like a smartphone, and as a result, the sensor device 1 can be easily gripped. Furthermore, in order to prevent the thumb 63 from slipping and coming off the front surface of the main body 2, there is no need to expand the area around the display screen 21. As a result, the sensor device can be made smaller.

[0026] [Second embodiment] Hereinafter, another embodiment of the present invention will be described. For the sake of convenience, components having the same functions as those described in the above embodiment are denoted by the same reference numerals, and their description will not be repeated.

[0027] Figure 7 is a side view of the sensing device 1a of the second embodiment. Figure 1 to Figure 6 Compared with the sensor device 1 shown in the figure, the protrusion 3 is changed to a protrusion 3a, and the other structures are the same. For the protrusion 3a, the cross-sectional area of ​​the protrusion 3a on the surface parallel to the back surface 22 relative to the display screen 21 increases according to the distance from the back surface 22.

[0028] Since the cross-sectional area of ​​the protrusion 3a increases with the distance from the back surface, it is difficult for the sensor device 1 to be moved from the back surface 22 of the main body 2 to the front surface 28 by the fingers of the hand 6 in contact with the side surface 31 of the protrusion 3a. Therefore, even when the sensor device 1a is held in a posture with the display screen 21 facing vertically downward, it is possible to prevent the sensor device 1a from falling.

[0029] [Third embodiment] Hereinafter, other embodiments of the present invention will be described. In addition, for the sake of convenience of description, components having the same functions as those described in the above embodiments are denoted by the same reference numerals, and their description will not be repeated.

[0030] Figure 8 FIG. 1 is a rear view of a sensing device 1b according to the third embodiment. Figure 1 to Figure 6 Compared with the sensing device 1 shown in the figure, the arrangement of the first sensor 4 is different, and the other structures are the same. The first sensor 4 and the second sensor 5 are arranged on a straight line perpendicular to the extending direction of the protrusion 3.

[0031] Fig. 9 FIG. 1 is a rear view of another sensing device 1c of the third embodiment. Figure 1 to Figure 6 Compared with the sensing device 1 shown in FIG. 1 , the configuration of the second sensor 5 is different, and the other structures are the same. The second sensor 5 is arranged on the protrusion 3. Furthermore, the first sensor 4 and the second sensor 5 are respectively arranged on both sides of the extension direction of the protrusion 3. In addition, the first sensor 4 can also be arranged with Figure 2 The arrangement of the first sensor 4 in the sensing device 1 shown is different, and may also be arranged from the center of the protrusion 3 to the side of the sensing device 1c.

[0032] That is, when the sensing device 1b is viewed from the back, the main body 2 has at least one side 22a or 22b, and the first sensor 4 and the second sensor 5 are arranged along the direction of the side 22a or 22b. Therefore, since the first sensor 4 and the second sensor 5 are arranged along the side 22a or 22b, the deviation between the measurement position of the first sensor 4 and the measurement position of the second sensor 5 can be easily corrected.

[0033] [Fourth embodiment] Hereinafter, other embodiments of the present invention will be described. In addition, for the sake of convenience of description, components having the same functions as those described in the above embodiments are denoted by the same reference numerals, and their description will not be repeated.

[0034] Fig.10 FIG. 1 is a rear view of a sensing device 1d according to the fourth embodiment. Figure 1 to Figure 6 Compared with the sensing device 1 shown in FIG. 1 , the difference is that the protrusion 3 is changed to the protrusion 3b, and the other structures are the same. The protrusion 3b is shorter than the protrusion 3 in the extension direction. Figure 8 Similarly, the first sensor 4 and the second sensor 5 are arranged in a direction parallel to the side 22b where the back surface 22 and the side surface 24 of the main body 2 intersect. In addition, the arrangement of the first sensor 4 and the second sensor 5 is not limited to this. For example, Figure 1 As shown, the first sensor 4 and the second sensor 5 may be arranged in a direction different from the direction parallel to the side 22 b.

[0035] In this case, the operator can also hold the sensor device 1d by the protruding portion 3b, similarly to the first embodiment.

[0036] Fig.11 FIG. 1 is a rear view of another sensing device 1e according to the fourth embodiment. Figure 1 to Figure 6 Compared with the sensing device 1 shown in the figure, the difference is that the protrusion 3 is changed to a protrusion 3c, and the other structures are the same. The protrusion 3c is a cylindrical shape protruding from the central part of the back side of the main body 2. Fig.11 Zhong Ye and Figure 8 Similarly, the first sensor 4 and the second sensor 5 are arranged in a direction parallel to a side 22 b where the back surface 22 and the side surface 24 of the main body 2 intersect.

[0037] In addition, the configuration of the first sensor 4 and the second sensor 5 is not limited thereto. Figure 1 As shown, the first sensor 4 and the second sensor 5 may be arranged in a direction different from the direction parallel to the side 22 b.

[0038] In this case, the operator can also hold the sensor device 1e by the protruding portion 3c, similarly to the first embodiment.

[0039] As described above, any shape may be adopted as long as the protrusions 3 b and 3 c can be held by the hand 6 .

[0040] [Fifth embodiment] Hereinafter, other embodiments of the present invention will be described. In addition, for the sake of convenience of description, components having the same functions as those described in the above embodiments are denoted by the same reference numerals, and their description will not be repeated.

[0041] Fig.12 is a rear view of the sensing device 1f of the fifth embodiment. Figure 1 to Figure 6 Compared with the sensing device 1 shown in the figure, the difference is that the protrusion 3 is changed to a protrusion 3d and a protrusion 3e, and the other structures are the same. In this way, the sensing device 1f can also include a plurality of protrusions. Furthermore, the first sensor 4 and the second sensor 5 are respectively provided on the protrusion 3d and the protrusion 3e. Thus, the first sensor 4 and the second sensor 5 can measure the object without being blocked by the operator's hand. Furthermore, the first sensor 4 and the second sensor 5 are arranged in a direction perpendicular to the edge 22b where the back 22 and the side 24 of the main body 2 intersect.

[0042] The arrangement of the first sensor 4 and the second sensor 5 is not limited thereto. The first sensor 4 and the second sensor 5 may be arranged in a direction different from the direction perpendicular to the side 22b. Furthermore, the number of the protrusions may be three or more (≥3).

[0043] According to the above configuration, when the sensing device 1f is held by the left hand, the protrusion 3d is used, and when the sensing device 1f is held by the right hand, the protrusion 3e is used to hold the sensing device 1f at a position that is easy to hold and the protrusion closest to the hand 6. Compared with the sensing device 1e in the fourth embodiment, the protrusion 3d and the protrusion 3e are provided on one side of the side 24, so that the fingers of the hand 6 can be hooked on the side 31 of the protrusion 3d or the protrusion 3e to hold the sensing device 1f.

[0044] [Sixth embodiment] Hereinafter, another embodiment of the present invention will be described. For the sake of convenience, components having the same functions as those described in the above embodiment are denoted by the same reference numerals, and their description will not be repeated.

[0045] Fig.13 is a rear view of a sensing device 1g according to the sixth embodiment. Figure 1 to Figure 6Compared with the sensing device 1 shown in the figure, the difference is that the protrusion 3 is changed to a protrusion 3f, and the other structures are the same. The protrusion 3f extends in a direction parallel to the edge 22b where the back surface 22 and the side surface 24 of the main body 2 intersect, and the first sensor 4 and the second sensor 5 are arranged at both ends of the extension direction of the protrusion 3f. The protrusion 3f is configured to be able to slide on the back surface 22 of the main body 2 in a direction parallel to the above-mentioned edge 22b. Furthermore, on the front surface 28 of the main body 2, a recess 23 can also be formed between the display screen 21 and the upper surface 26, and a recess 23 can also be formed between the display screen 21 and the lower surface 27.

[0046] In this case, the sensing device 1g can be rotated 90 degrees to hold the display screen 21 in a horizontally long manner. Furthermore, since the protrusion 3f can slide in a direction parallel to the side 22b of the main body 2, the protrusion 3f can be held on either side of the upper surface 26 or the lower surface 27 by sliding the protrusion 3f to a position that is easy to hold on the side of the hand being held. In addition, the sliding direction of the protrusion 3f is not limited to the direction parallel to the side 22b, and can slide in a direction perpendicular to the side 22b, or in any direction that is neither parallel to nor perpendicular to the side 22b.
