Below, while appropriately referring to the drawings, the implementation modes are described in detail. However, sometimes unnecessary detailed descriptions are omitted. For example, sometimes detailed descriptions of matters that are already widely known or repeated descriptions of substantially the same structures are omitted. The purpose is to avoid excessive redundancy in the following descriptions and to make it easy for people with ordinary knowledge in the relevant technical field to understand. In addition, the purpose of the inventor providing the drawings and the following descriptions is to enable people with ordinary knowledge in the relevant technical field to fully understand the present invention, and it is not intended to limit the technical ideas described in the scope of the patent application by these.

Fig. 1 is a perspective view of an optical fiber sensor according to an embodiment of the present invention. Fig. 2 is an exploded perspective view of the optical fiber sensor.

As shown in FIG1 , a type of sensing device, namely, an optical fiber sensor 1, is in the shape of a thin box, and one side surface thereof is provided with holes 71 and 72 into which the optical fiber described later is inserted. The optical fiber sensor 1 is connected to the optical fibers corresponding to the light-emitting part and the light-receiving part, respectively, and the front ends of the light-emitting part and the light-receiving part are arranged at positions where the detected object can be detected. In this example, the outgoing light from the light-emitting part is transmitted in the optical fiber connected to the hole 71, and is emitted from the other end of the optical fiber. The emitted light is the reflected light obtained by receiving the reflection from the detected object, which is transmitted in the optical fiber connected to the hole 72 and is emitted into the light-receiving part. The light emitted into the photoelectric conversion element of the light-receiving part is converted into an electrical signal and amplified by the light-receiving amplifier. Then, for example, the optical fiber sensor 1 compares the electrical signal with a predetermined critical value in a comparison circuit to determine whether there is a detected object, measure the amount of received light, or perform processing based on the amount of received light.

Furthermore, the inventors define coordinates including an X-axis parallel to the longitudinal direction of the optical fiber sensor 1, a Y-axis parallel to the width direction of the optical fiber sensor 1, and a Z-axis parallel to the height direction of the optical fiber sensor 1. Furthermore, the inventors use the coordinates in the following description.

As shown in FIG. 1 and FIG. 2 , the optical fiber sensor 1 includes a housing 3 , a substrate 5 , a display device 6 , an optical fiber holding portion 7 , an indication portion 8 , and an operation portion 9 .

The housing 3 forms the outer periphery of the optical fiber sensor 1 and houses various components. The housing 3 includes a first housing 3A and a second housing 3B, which are made of resin, for example. The first housing 3A and the second housing 3B are combined to define a space inside the housing 3.

The substrate 5 is formed of, for example, a printed circuit board (PCB) and is housed inside the housing 3. The substrate 5 is provided with various electronic components. The substrate 5 has a power connection portion 5A connected to an external power source. In particular, the substrate 5 is provided with two first switches 10 and two second switches 20. These switches are described below.

The display device 6 includes, for example, a liquid crystal display and a driving device for the liquid crystal display, and displays the operation mode of the optical fiber sensor 1, the amount of light received, or a predetermined critical value compared with the amount of light received. The optical fiber holding portion 7 has holes 71 and 72 exposed to the outside, and holds the connected optical fiber. The indicator portion 8 displays the emitted light from the light source 30 described later (see FIG. 5, etc.). The operating portion 9 includes: a plurality of covers covering the first switch 10 and the second switch 20 arranged on the substrate 5; the user can operate the first switch 10 and the second switch 20 by pushing the covers. In addition, liquid crystal displays include: displays that can display dot matrix, organic electroluminescence (OEL) displays, or organic light emitting diodes (OLED) and the like.

Figure 3 is a top view of the fiber optic sensor with an operating cover. Figure 4 is a top view of the fiber optic sensor without an operating cover.

As shown in FIG. 3 and FIG. 4 , the indicator 8, the display device 6, and the operating portion 9 are arranged on the operating surface 3c constituting a part of the outer surface of the housing 3, and the user can operate the operating portion 9 while recognizing the indicator 8 and the display device 6. In the operating portion 9, two first switch covers 14 covering the two first switches 10 (refer to FIG. 2 ) and two second switch covers 24 covering the two second switches 20 are arranged along the X-axis direction and exposed.

As shown in FIG3 , an operation surface cover 3C (specifically, a nameplate) is mounted on the operation surface 3c, and the user can operate the operation portion 9 while referring to the text, arrows, etc. recorded on the operation surface cover 3C. As shown in FIG2 , the operation surface 3c has an operation surface top portion 3c1 and an operation surface bottom portion 3c2 opposite to the operation surface top portion 3c1. Between the operation surface top portion 3c1 and the operation surface bottom portion 3c2, the display device 6 is inserted and mounted therein and is held (also includes being locked or fixed).

The operation surface 3c is disposed between the first wall portion 3a forming the main surface of the first housing 3A and the second wall portion 3b forming the main surface of the second housing 3B. That is, the first wall portion 3a and the second wall portion are opposite to each other, and as shown in FIG5 , the substrate 5 is accommodated in the space between the first wall portion 3a and the second wall portion 3b. The substrate 5 has a first surface 5b and a second surface 5a on both sides, and the first surface 5b is opposite to the second wall portion 3b, and the second surface 5a is opposite to the first wall portion 3a.

FIG. 5 is a top view of the optical fiber sensor without the operating cover, the first switch cover, and the second switch cover.

As shown in FIG5 , a light source 30 composed of a light emitting diode (LED) or the like is mounted on a substrate 5 . Light emitted from the light source 30 is displayed to the outside via an indicator 8 .

Next, the first switch 10 and the second switch 20 disposed on the substrate 5 are described. The first switch 10 is disposed on the first surface 5b of the substrate 5, and the second switch 20 is disposed on the second surface 5a of the substrate 5. That is, the first switch 10 and the second switch 20 are disposed on two opposite surfaces of the substrate 5, respectively, and are not directly adjacent to each other.

The first switch 10 and the second switch 20 are arranged at positions staggered from each other along the X-axis direction, which is the first direction, i.e., the long side direction of the optical fiber sensor 1 (housing 3). In this embodiment, the two first switches 10 and the two second switches 20 are arranged alternately.

Fig. 6 is a side view parallel to the line VI-VI in Fig. 3. Fig. 7 is a side view parallel to the line VII-VII in Fig. 3. Fig. 8 is a side view parallel to the line VIII-VIII in Fig. 3. Fig. 9 is a side view parallel to the line IX-IX in Fig. 3.

The user pushes the first switch cover 14 and the second switch cover 24 exposed from the operation surface 3c to operate the first switch 10 and the second switch 20, and the optical fiber sensor 1 operates according to the operation. As shown in FIG. 4 and FIG. 6 to FIG. 9 , the operation of the first switch cover 14 is transmitted to the first switch 10 via the first flexible member 12. In addition, the operation of the second switch cover 24 is transmitted to the second switch 20 via the second flexible member 22.

As shown in FIG6 and FIG7, the first flexible member 12 protrudes from the first wall portion 3a of the housing 3 and extends along the second direction perpendicular to the X-axis direction, that is, the Y-axis direction, and can contact the first switch 10. In this embodiment, the first flexible member 12 is formed into a beam shape and protrudes from the first wall portion 3a, for example, it is composed of a resin integrally formed with the first wall portion 3a. The first flexible member 12 may also be a member configured separately from the first wall portion 3a.

The first flexible member 12 is a beam-shaped member, and its end opposite to the first wall portion 3a is an open end, and the first switch cover 14 is arranged near the open end. The first switch cover 14 and the open end are arranged adjacent to the first switch 10 on the upper side of the first switch 10, that is, in the Z-axis direction as the third direction.

Therefore, when the user pushes the first switch cover 14 , the first flexible member 12 is bent in the pushing direction (downward) to push the first switch 10 to drive the first switch 10 .

As shown in FIG8 and FIG9, the second flexible member 22 protrudes from the second wall portion 3b of the housing 3 and extends along the Y-axis direction to contact the second switch 20. In this embodiment, the second flexible member 22 is formed into a beam shape and protrudes from the second wall portion 3b, for example, by a resin integrally formed with the second wall portion 3b. The second flexible member 22 may also be a member disposed separately from the second wall portion 3b.

The second flexible member 22 is a beam-shaped member, and its end opposite to the second wall portion 3b is an open end, and the second switch cover 24 is arranged near the open end. The second switch cover 24 and the open end are arranged adjacent to the second switch 20 on the upper side of the second switch 20, that is, in the Z-axis direction as the third direction.

Therefore, when the user pushes the second switch cover 24 , the second flexible member 22 is bent in the pushing direction (downward) to push the second switch 20 to drive the second switch 20 .

Fig. 10A is a schematic diagram schematically showing the parallel switch mode. Fig. 10B is a front view of the parallel switch mode observed from the front.

As shown in FIG. 10A , the first switch 10 and the second switch 20 adjacent to each other in the X-axis direction are arranged such that the area where the first switch 10 is arranged and the area where the second switch 20 is arranged at least partially overlap.

FIG10B provides a more detailed description of the overlapping method of the configuration area. The first switch 10 is configured in the first configuration area A1, located on the first surface 5b of the substrate 5. The second switch 20 is configured in the second configuration area A2, located on the second surface 5a of the substrate 5. FIG10B omits the substrate 5, the first switch 10 is located at the front side of the paper relative to the substrate 5 not shown, and the second switch 20 is located at the inside of the paper relative to the substrate 5 not shown. In addition, in FIG10B, the position of the first switch 10 shows the position of the switch body of the first switch 10, and the position of the second switch 20 shows the position of the switch body of the second switch 20.

Furthermore, the first configuration area A1 and the second configuration area A2 at least partially overlap in the first direction, i.e., the X-axis direction. The overlapping area B of FIG. 10B shows the overlapping area of the first configuration area A1 and the second configuration area A2. Although the overlapping area of the configuration area is located in the X-axis direction, the first switch 10 and the second switch 20 are arranged on different surfaces of the substrate 5 and are therefore not directly adjacent.

According to this structure, since the first configuration area A1 configured with the first switch 10 and the second configuration area A2 configured with the second switch at least partially overlap in the X-axis direction parallel to the outer edge of the housing 3, the optical fiber sensor 1 can be shortened in the X-axis direction to achieve miniaturization.

Specifically, the first configuration area A1 includes: a first body area, where the switch body of the first switch 10 is configured; and a first auxiliary area, where a first mounting auxiliary component is configured, which is used to mount the first switch 10 on the substrate 5. The second configuration area A2 includes: a second body area, where the switch body of the second switch 20 is configured; and a second auxiliary area, where a second mounting auxiliary component is configured, which is used to mount the second switch 20 on the substrate 5. The mounting auxiliary component is used to mount the switch on the substrate 5, such as solder, adhesive, lead wire, etc. In this embodiment, the first auxiliary area and the second auxiliary area may at least partially overlap in the X-axis direction. Furthermore, in the operating portion 9, as long as the first switch 10 and the second switch 20 can be arranged in a straight line in the X-axis direction, the first body area and the second body area can at least partially overlap in the X-axis direction.

Thereby, the optical fiber sensor 1 can avoid overlapping of auxiliary components between different switches located in the operating part 9, and suppress electrical malfunction of the optical fiber sensor 1, while shortening the length in the X-axis direction, thereby miniaturizing the optical fiber sensor 1.

In addition, each switch has a pad P, and two pads P are arranged adjacent to each other in the Z-axis direction. The pad P of the first switch 10 and the pad P of the second switch 20 are separated by a distance D1 or a distance D2; the two pads P adjacent to each other in the Z-axis direction are separated by a distance D3. The distance D1, the distance D2, and the distance D3 are arbitrary values, but by making the distance D1 and the distance D2 smaller than the distance D3, the length in the X-axis direction can be further shortened.

In addition, in this embodiment, as shown in FIGS. 6 to 9 , the length of the first flexible member 12 in the Y-axis direction is longer than the length of the second flexible member 22 in the Y-axis direction. The first flexible member 12 and the second flexible member 22 are formed of the same material, and the first flexible member 12 is easier to bend than the second flexible member 22. Therefore, the resistance to the push operation of the first switch cover 14 corresponding to the first flexible member 12 is smaller than the resistance to the push operation of the second switch cover 24 corresponding to the second flexible member 22.

Thus, the optical fiber sensor 1 can make the operating force when the first switch 10 is pressed different from the operating force when the second switch 20 is pressed, so that the first switch 10 and the second switch 20 are respectively different types of switches, thereby improving operability.

For example, the first switch 10 may include: a positive switch 10a, which sends various setting values in a forward direction; or a negative switch 10b, which sends the setting value in a reverse direction. The second switch 20 may include: a setting switch 20a, which performs a predetermined setting; or a mode switch 20b, which sets the operation mode of the optical fiber sensor 1. The frequency of use of the positive switch 10a or the negative switch 10b is higher than the frequency of use of the setting switch 20a or the mode switch 20b.

Thereby, the optical fiber sensor 1 can set the operating force of the first switch 10 with a high frequency of use to be smaller than the operating force of the second switch 20 with a low frequency of use, thereby improving operability.

The substrate 5 is arranged along the imaginary plane parallel to the first wall 3a and the second wall 3b of the housing 3, i.e., the XZ plane. However, as shown in FIG5 , the substrate 5 is arranged closer to the second wall 3b than the center of the housing 3 in the Y-axis direction (shown by the CC line in FIG5 ).

In addition, the light source 30 is mounted on the substrate 5 , but the light source 30 is arranged on the second surface 5 a of the substrate 5 and in the center portion in the Y-axis direction (on the CC line in FIG. 5 ).

Thus, the optical fiber sensor 1 can emit light that is not deflected in the Y-axis direction by disposing the light source 30 at the center of the housing 3 in the second direction, so as to ensure good appearance and recognition when emitting light.

Furthermore, the first switch cover 14 and the second switch cover 24 are exposed from the operation surface 3c, but the first switch cover 14 and the second switch cover 24 are arranged at the same position in the Y-axis direction. That is, the first switch cover 14 and the second switch cover 24 are arranged on a straight line.

Thus, even if the first switch 10 and the second switch 20 are arranged on different surfaces of the substrate 5, the first switch cover 14 and the second switch cover 24 exposed in the optical fiber sensor 1 are arranged side by side at the same position in the Y-axis direction of the housing 3, thereby ensuring the appearance design of the optical fiber sensor 1.

FIG11 is a schematic diagram schematically showing a switch parallel mode, (a) is a schematic diagram schematically showing a switch parallel mode of an optical fiber sensor of a known example, and (b) is a schematic diagram schematically showing a switch parallel mode of an optical fiber sensor of an implementation form of the present invention.

In the conventional optical fiber sensor shown in FIG. 11( a ), since the first switch 10 and the second switch 20 are arranged on the same surface of the substrate 5 , the length L1 of the operating portion 9 on which the switches are arranged becomes longer. On the other hand, in the optical fiber sensor of the present embodiment shown in FIG. 11( b ), since the first switch 10 and the second switch 20 are arranged on different surfaces of the substrate 5 , the length L2 of the operating portion 9 on which the switches are arranged can be shortened.

In addition, this embodiment is related to the optical fiber sensor 1, but the technology of the present invention can also be used in other sensing devices. For example, the optical fiber sensor 1 has an optical fiber holding portion 7 at one end in the X-axis direction for holding the optical fiber, and a power connection portion 5A at the other end in the X-axis direction for connecting to an external power source.

That is, one end of the optical fiber sensor 1 in the long direction is connected to an optical fiber, and the other end is connected to a power cable for supplying external power. When the optical fiber sensor 1 is installed in the user equipment, there must be space in the long direction of the optical fiber sensor 1 for winding the optical fiber and the power cable.

By miniaturizing the optical fiber sensor 1 in the X-axis direction, that is, the long side direction, a larger space for winding the optical fiber and the power cable can be ensured in the user equipment.

In the optical fiber sensor 1, by ensuring space, the burden on the optical fiber can also be reduced. That is, when the optical fiber is bent near the mounting portion when the optical fiber is mounted on the optical fiber sensor 1, the incident amount will be unstable. However, by ensuring the above-mentioned space, the optical fiber sensor 1 can maintain the optical fiber in a straight state or a slightly bent state near the mounting portion, thereby ensuring the stability of the incident amount.

Furthermore, the substrate 5 is adjacent to the display device 6 below the display device 6, that is, in the Z-axis direction as the third direction. The display device 6 is arranged near the second wall portion 3b of the housing 3 in the second direction, that is, in the Y-axis direction. The substrate 5 is also arranged near the second wall portion 3b, but relative to the display portion of the display device 6, it is arranged near the first wall portion 3a.

In addition, in the optical fiber sensor 1, only predetermined components are arranged on the first surface 5b of the substrate 5, and other components are arranged on the second surface 5a of the substrate 5. That is, in the optical fiber sensor 1, when components are installed on the substrate 5, they can be concentrated on a single surface (the first surface 5b or the second surface 5a). For example, the first surface 5b is only equipped with the first switch 10, or is equipped with the first switch 10 and the first mounting auxiliary component for mounting the first switch 10. For example, the second surface 5a is equipped with: other components in the optical fiber sensor 1 (such as the second switch 20, the second mounting auxiliary component for mounting the second switch 20, the light source 30, the optical fiber holding portion 7, the power connection portion 5A, the light-emitting module, the light-receiving module, and the area for welding the light-emitting module or the light-receiving module, etc.).

As mentioned above, the present invention includes at least the following items. In addition, the corresponding components in the above embodiments are described in parentheses as examples, but are not limited to these.

(1) A sensing device (optical fiber sensor 1) having a plurality of switches; The sensing device comprises: A housing (housing 3) having a first wall (first wall 3a); and a second wall (second wall 3b) opposite to the first wall; A substrate (substrate 5) housed in a space between the first wall and the second wall of the housing, and having: a first surface (first surface 5b) opposite to the second wall, and a second surface (second surface 5a) opposite to the first wall; A first switch (first switch 10) disposed on the first surface of the substrate; A second switch (second switch 20) disposed on the second surface of the substrate at a position staggered from the first switch along a first direction (X-axis direction) parallel to the outer edge of the housing; The first flexible member (first flexible member 12) protrudes from the first wall of the housing and extends along the second direction (Y-axis direction) perpendicular to the first direction, and can contact the first switch; and The second flexible member (second flexible member 22) protrudes from the second wall of the housing and extends along the second direction, and can contact the second switch; The first switch and the second switch adjacent to each other in the first direction at least partially overlap in the first direction; the first configuration area (first configuration area A1) where the first switch is configured and the second configuration area (second configuration area A2) where the second switch is configured at least partially overlap in the first direction.

Thus, in the sensing device, since the first configuration area where the first switch is configured and the second configuration area where the second switch is configured at least partially overlap in the first direction parallel to the outer edge of the housing, the length of the sensing device in the first direction can be shortened, thereby miniaturizing the sensing device.

(2) A sensing device as described in (1), wherein the length of the first flexible member along the second direction is longer than the length of the second flexible member along the second direction.

Thereby, the sensing device can make the operating force when the first switch is pressed different from the operating force when the second switch is pressed, so that the first switch and the second switch respectively adopt different types of switches, thereby improving operability.

(3) A sensing device as described in (1) or (2), wherein: the first switch includes: a positive switch (positive switch 10a) for sending a setting value in a forward direction; and a negative switch (negative switch 10b) for sending the setting value in a reverse direction; the second switch includes: a setting switch (setting switch 20a) for performing a predetermined setting; or a mode switch (mode switch 20b) for setting an operation mode of the sensing device.

Thereby, the sensing device can set the operating force of the first switch with a high frequency of use to be smaller than the operating force of the second switch with a low frequency of use, thereby improving operability.

(4) The sensing device as described in any one of (1) to (3), further comprising: A light source (light source 30) mounted on the substrate; The substrate is arranged along an imaginary plane (XZ plane) parallel to the first wall and the second wall of the housing, and the substrate is arranged at: a portion of the housing closer to the second wall than the center portion in the second direction; The light source is arranged at: a portion of the housing in the center portion in the second direction.

Thereby, the sensing device can emit light that is not deflected in the second direction by arranging the light source at the center of the housing in the second direction, so as to ensure good appearance and recognition when emitting light.

(5) A sensing device as described in any one of (1) to (4), wherein: the first configuration area includes: a first auxiliary area, configured with a first mounting auxiliary member, which is used to mount the first switch on the substrate; the second configuration area includes: a second auxiliary area, configured with a second mounting auxiliary member, which is used to mount the second switch on the substrate; the first switch and the second switch adjacent to each other in the first direction at least partially overlap in the first direction; the first auxiliary area of the first switch and the second auxiliary area of the second switch at least partially overlap in the first direction.

Thereby, the sensing device can avoid overlapping of auxiliary installation components such as solder and leads between different switches, and suppress electrical malfunction of the sensing device, while shortening the length in the first direction, thereby miniaturizing the sensing device.

(6) A sensing device as described in any one of (1) to (5), wherein: the first configuration area includes: a first body area, in which the switch body of the first switch is configured; the second configuration area includes: a second body area, in which the switch body of the second switch is configured; the first switch and the second switch adjacent to each other in the first direction at least partially overlap in the first direction; the first body area of the first switch and the second body area of the second switch at least partially overlap in the first direction.

Thereby, the sensing device can avoid the overlap of switch bodies between different switches, and suppress the sensing device from performing electrical malfunctions, while shortening the length in the first direction, thereby miniaturizing the sensing device.

(7) A sensing device as described in any one of (1) to (6), wherein: the housing has: an operating surface (operating surface 3c) disposed between the first wall portion and the second wall portion and constituting a portion of the outer side surface of the housing; the sensing device further comprises: a first switch cover (first switch cover 14) exposed from the operating surface and operable to operate the first flexible member; and a second switch cover (second switch cover 24) exposed from the operating surface and operable to operate the second flexible member; the first switch cover and the second switch cover are disposed at the same position in the second direction in the housing.

Thus, in the sensing device, even if the first switch and the second switch are arranged on different surfaces of the substrate, the exposed first switch cover and the second switch cover are arranged side by side at the same position in the second direction of the housing, thereby ensuring the appearance design of the sensing device.

(8) A sensing device as described in (7), wherein: the operating surface has: an operating surface top (operating surface top 3c1); and an operating surface bottom (operating surface bottom 3c2), which is opposite to the operating surface top; a display device (display device 6) is inserted and held between the operating surface top and the operating surface bottom.

Thereby, the sensing device can easily fix the display device on the housing.

(9) A sensing device as described in any one of (1) to (8), wherein: The first surface of the substrate is provided with only the first switch; The second surface of the substrate is provided with other parts including the second switch.

Thus, in the sensing device, by centrally arranging most of the parts on one side of the second surface of the substrate, the substrate can be arranged at the end side relative to the center of the second direction, which will easily ensure a larger space between the substrate and the housing, making it easier for most of the parts to work in coordination. In addition, since almost all of the parts or components are arranged on one side of the second surface, they can be placed or fixed from the same direction during assembly, making it easy to assemble, thereby reducing manufacturing time or manufacturing costs.

(10) A sensing device as described in (9), wherein: The first surface of the substrate is only provided with: the first switch and a first mounting auxiliary component for mounting the first switch; The second surface of the substrate is provided with: the second switch and other electronic components including a second mounting auxiliary component for mounting the second switch.

Thus, in the sensing device, by centrally arranging most of the parts on the second side of the substrate, the substrate can be arranged closer to the end than the center in the second direction, which makes it easy to ensure a larger space between the substrate and the housing, so that most of the parts can easily work in coordination. In addition, since almost all of the parts or components are arranged on the second side and further installed, they can be loaded, fixed, installed, etc. from the same direction during assembly, which makes it easy to assemble (in terms of construction method) and reduces manufacturing time or manufacturing cost.

(11) A sensing device as described in any one of (1) to (10), wherein: The sensing device is an optical fiber sensor (optical fiber sensor 1); The optical fiber sensor comprises: An optical fiber holding portion (optical fiber holding portion 7) holding the optical fiber at one end in the first direction; and A power connection portion (power connection portion 5A) connected to an external power source at the other end in the first direction.
