Summary of the Invention

Problems to be Solved by the Invention

[0004] However, regarding the test of the sensor of Patent Document 1, for example, heat was applied to the sensor using a cylindrical test jig that covers at least a part of the sensor. Therefore, while heat was being applied with at least a part of the sensor covered by the test jig, the display lamp of the sensor was hidden by the test jig and became impossible to visually recognize, and there was a possibility that the user could not grasp information regarding the test while heat was being applied.

[0005] Therefore, there was room for improvement from the viewpoint of enabling the user to grasp information regarding the test even when at least a part of the sensor is covered by the test jig.

[0006] The present invention has been made in view of the above problems, and an object thereof is to provide a disaster prevention device that enables information regarding a test to be grasped even when at least a part of the disaster prevention device is covered by a test device.

The protective means includes a spectroscopic part for allowing light from the light emitting means to enter the protective means and also to enter the light guiding means. At least a part of the light guiding means is exposed outside the test device when the protective means is covered with the test device for testing the disaster prevention device, and the light incident on the light guiding means can be visually recognized from outside the test device. The light emitting means is arranged to output light toward the side surface of the outer cover, and the light from the light emitting means does not directly enter the protective means.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the disaster prevention device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by the embodiments.

[0012] 〔Basic Concepts of the Embodiment〕 First, the basic concepts of the embodiment will be described. The embodiment generally relates to disaster prevention devices.

[0013] A "disaster prevention device" is a device used for disaster prevention, and includes, for example, a device for detecting an abnormality in a monitoring area, and as an example, includes a heat sensor, a fire sensor, a gas sensor, a smoke sensor, and the like. Further, a "disaster prevention device" includes, for example, an outer cover and a display means.

[0014] The "monitoring area" refers to the area to be monitored by disaster prevention equipment. Specifically, it is a space with a certain extent, for example, a concept including rooms in a building (such as Room A on the first floor, Room B on the first floor, etc.), corridors, stairways, etc. Also, the "abnormality of the monitoring area" means that the state of the monitoring area is different from normal. Specifically, it is a concept including fire occurrence, gas leakage, etc.

[0015] The "outer cover" refers to, for example, something that covers at least a part of the components of disaster prevention equipment.

[0016] The "display means" is a means that outputs at least information related to the test of disaster prevention equipment by emitting light, and is a means provided on the outer cover. Specifically, in order to conduct a test of disaster prevention equipment, when at least a part of the outer cover is covered by a test device, at least a part of the display surface of the display means is exposed outside the test device, or it includes concepts such as parts.

[0017] Also, the "display means" includes, for example, concepts such as something or a part protruding from the side surface of the cover, and also includes concepts such as something or a part formed at least at the edge of the front part of the outer cover, and also includes concepts such as light guiding means, and also includes concepts such as thin parts. Also, the "display surface of the display means" is, for example, a surface that is exposed outside the disaster prevention equipment in the display means, is a surface that emits light, and includes concepts such as a surface that can be visually recognized by users.

[0018] The "light guiding means" is, for example, a means formed on the outer cover, and includes concepts such as something or a part that guides the light from the light emitting means. The "thin part" is, for example, a part that is thinner than other parts of the outer cover, and includes concepts such as a part irradiated with the light from the light emitting means, and also includes concepts such as a part that transmits a part of the irradiated light. The "light emitting means" is, for example, a means that outputs light.

[0019] And in each of the embodiments described below, the case where the "disaster prevention device" is a heat sensor will be described. In particular, in Embodiment 1, the case where the display means is a light guide means will be described, and in Embodiment 2, the case where the display means is a thin-walled portion will be described.

[0020] [Specific content of the embodiment] Next, the specific content of the embodiment will be described.

[0021] (Embodiment 1) First, Embodiment 1 will be described. In this embodiment, the case where the display means is a light guide means will be described.

[0022] (Configuration - Sensor) First, the configuration of the sensor according to this embodiment will be described. FIG. 1 is a perspective view of the sensor in the embodiment of the present invention, FIG. 2 is a plan view of the sensor, FIG. 3 is a side view of the sensor, and FIG. 4 is a cross-sectional view taken along line A - A of FIG. 2. In each figure, the Z-axis indicates the vertical direction, and the X-axis and Y-axis orthogonal to the Z-axis indicate the horizontal direction for the purpose of explanation. Also, for example, the "front portion", "rear portion", and "side portion" will be described as terms referring to a part of the sensor 100. Specifically, when the sensor 100 is installed on the mounting target 900 which is the ceiling surface, the side located on the floor surface side of the sensor 100 (the side opposite to the mounting target 900 with respect to the sensor 100) (the -Z direction in FIG. 3) is referred to as the "front portion", and the side facing the mounting target 900 which is the ceiling surface of the sensor 100 (the +Z direction in FIG. 3) is the "rear portion". And the peripheral surface connecting the "front portion" and the "rear portion" of the sensor 100 is the "side portion". Note that the definitions of these "front portion", "rear portion", and "side portion" are the same in Embodiment 2 as well.

[0023] The sensor 1 in each of FIGS. 1 to 4 is a disaster prevention device, specifically a heat sensor that detects heat. For example, it is attached to the mounting target 900 which is the ceiling surface via the mounting portion 101 (for example, the so-called "sensor base", the detailed structure of which is not shown) of the sensor 100 in FIG. 3. As an example, it includes an outer cover 11, a protection part 12, a prevention part 13 in FIG. 1, a thermistor 14, and a light emitting part 15 in FIG. 4.

[0024] (Configuration - Sensor - Outer Cover) The outer cover 11 in FIG. 1 covers at least a part of the components of the sensor 100. The specific type and configuration of this outer cover 11 are arbitrary. For example, as shown in FIG. 3, it includes a cylindrical part with the same diameter even when separated from the mounting portion 101, and a tapered part with a smaller diameter as it moves away from the mounting portion 101. Also, except for the specifically noted parts, it has light-shielding properties, and it includes a light guide part 111 and an operation hole 112 in FIG. 2. Note that "light-shielding property" is the performance of blocking light, for example, it indicates a concept such as the performance of not allowing light to pass from the inside to the outside of the outer cover 11.

[0025] The light guide part 111 is the aforementioned display means and also a light guiding means. The specific type and configuration of this light guide part 111 are arbitrary. For example, it is formed on a part of the outer cover 11, and is formed of an arbitrary material to function as a light guide that guides and emits light. Also, it is formed separately from the light-shielding part of the outer cover 11, and allows light to pass from the inside to the outside of the outer cover 11. Also, the light guide part 111, for example, has a display surface (the surface exposed to the outside of the sensor 100 shown in FIGS. 2 and 3) that extends from the front part side (-Z direction) to the side part side (+X direction or -X direction) of the outer cover 11, and two are provided. Also, as shown in FIG. 2, the display surface of the light guide part 111 is linear when viewed from the front part side of the outer cover 11, and is provided at a position corresponding to the position of the operation hole 112.

[0026] The operation hole 112 is an operation means for physically operating the sensor 100. The specific type and configuration of this operation hole 112 are arbitrary. For example, it is a hole into which a protrusion of a predetermined jig is inserted to rotate the outer cover 11 of the sensor 100 with respect to the mounting portion 101.

[0027] (Configuration - Sensor - Protection Part) The protection part 12 in FIG. 1 is a detection element protection means. The "detection element protection means" is, for example, something that houses and protects the thermistor 14 which is a detection element. The specific type and configuration of this protection part 12 are arbitrary. For example, it is formed as a part of the outer cover 11, and is formed of an arbitrary material in order to function as a light guide that guides and emits light. Also, it is formed separately from the light-shielding part of the outer cover 11, and allows light to pass from the inside to the outside of the outer cover 11. Further, the protection part 12 protects, for example, the thermistor 14 in FIG. 4, and has a hollow part for housing the thermistor 14. It protrudes from the outer cover 11 toward the opposite side (-Z direction) of the mounting portion 101, and is provided at the center of the outer cover 11 in the direction in which the outer cover 11 spreads (a direction parallel to the XY plane). Also, it is integrally formed with the light guide part 111. Further, the protection part 12 includes, for example, the frame part 121, the opening part 122 in FIG. 1, and the spectroscopic part 123 in FIG. 4.

[0028] The frame part 121 is, for example, a part that forms at least a part of the outer shape of the protection part 12, and is a part including one circular member that forms the tip part (-Z direction) of the sensor 100 and six support members that support the circular member between the circular member and the outer cover 11.

[0029] The opening part 122 is, for example, a part that allows a hot air flow to flow into or out of the thermistor 14 provided in the hollow part of the protection part 12, and is a part that is divided by the six support members of the aforementioned frame part 121 and six are provided.

[0030] The spectroscopic unit 123 is a part that refracts, disperses, or reflects the light output from the light-emitting unit 15, and is also a part facing the light-emitting unit 15.

[0031] (Configuration - Sensor - Prevention Unit) The prevention unit 13 in FIG. 1 is a prevention means for preventing a contact object from contacting the thermistor 14 housed in the protection unit 12. Note that the "contact object" is an object whose contact is prevented by the prevention unit 13, and is a concept including, for example, a user's finger or the like. The specific type and configuration of this prevention unit 13 are arbitrary, but for example, it is a protrusion provided in the opening 122.

[0032] (Configuration - Sensor - Thermistor) The thermistor 14 in FIG. 4 is a detection element. The "detection element" is, for example, a component for detecting a physical quantity of a detection target. The "physical quantity of the detection target" is, for example, a quantity that can be generated or changed due to an abnormality in the monitoring area, and as an example, it is a concept including temperature due to heat or a heat flow. The specific type and configuration of this thermistor 14 are arbitrary, but for example, it detects temperature due to heat or a heat flow, and also protrudes in a direction (Z-axis direction) orthogonal to the direction in which the outer cover 11 extends, and is housed in the protection unit 12.

[0033] (Configuration - Sensor - Light-Emitting Unit) The light-emitting unit 15 in FIG. 4 is the aforementioned light-emitting means. The specific type and configuration of this light-emitting unit 15 are arbitrary, but for example, it causes the light guide unit 111 and the protection unit 12 to emit light, and also outputs light toward the spectroscopic unit 123, and can be configured using a light-emitting diode or the like.

[0034] (Light Emission) Next, the light emission by the sensor 100 configured as described above will be explained. Note that the timing at which the sensor 100 emits light is arbitrary. For example, when outputting information regarding the test of the sensor 100, or when determining a fire based on the temperature of the heat detected by the thermistor 14 in the sensor 100, any arbitrary timing is assumed. Note that since the process by which the sensor 100 determines a fire can apply the same process as in the prior art, the explanation thereof is omitted. FIG. 5 is a diagram illustrating the optical path in FIG. 4.

[0035] A control unit (not shown) of the sensor 100 in FIG. 5 outputs light from the light emitting unit 15. In this case, the light from the light emitting unit 15 is refracted, dispersed, or reflected by the spectroscopic unit 123 and guided to the entire light guiding unit 111 and the protection unit 12 as shown in FIG. 5. Note that in FIG. 5, for convenience of explanation, only the optical path of the light from the light emitting unit 15 on the left side of the drawing is shown, but actually, light is also output from the light emitting unit 15 on the right side of the drawing and guided to the entire light guiding unit 111 and the protection unit 12. Then, the entire light guiding unit 111 and the protection unit 12 in FIG. 1 emit light.

[0036] (Test) Next, the test of the sensor 100 configured as described above will be explained. "Test" means to test the capabilities of the sensor 100. Note that the specific content of the test of this sensor 100 is arbitrary. For example, the case of performing a test of whether the sensor 100 detects the applied heat when simulating a fire occurrence using a test device described later and applying heat to the sensor 100 will be explained. Here, for example, it is assumed that the control unit of the sensor 100 acquires the temperature detection result by the thermistor 14, detects a fire when the acquired temperature is equal to or higher than a threshold value, and outputs information indicating that the sensor 100 has detected a fire in the test by continuously outputting red light from the light emitting unit 15 in FIG. 4. The following explanation will be made based on this assumption.

[0037] FIG. 6 is a side view showing the test apparatus and the sensor, FIG. 7 is a view showing the test jig with respect to the cross-sectional view of FIG. 4, and FIG. 8 is a view showing the test adapter with respect to the cross-sectional view of FIG. 4. In FIGS. 7 and 8, for convenience of explanation, the test jig 81 and the test adapter 82 are shown by a dashed line. Also, in FIGS. 7 and 8, a part of the sensor 100 is provided in the hollow portion inside the test jig 81 and the test adapter 82 and is actually in a state where it cannot be seen, but for convenience of explanation, it is shown by a solid line. The test of the sensor 100 is performed using the test apparatus 800 of FIG. 6.

[0038] (Test - Test Apparatus) The test apparatus 800 is an apparatus used for testing the sensor 100. For example, as shown in FIG. 6, it includes a handle portion and the test jig 81, and optionally includes the test adapter 82 of FIG. 8.

[0039] (Test - Test Apparatus - Test Jig) The test jig 81 is the aforementioned test apparatus. Specifically, it is provided at the tip of the rod-shaped handle portion of the test apparatus 800. For example, it is a cylindrical shape having a hollow portion for accommodating at least a part of the sensor 100 (such as the protection portion 12, etc.) inside and applying heat, and is made of metal. The size of this test jig 81 is arbitrary. For example, as shown in FIG. 7, the case where the outer diameter of the test jig 81 is larger than the outer diameter of the sensor 100 and the inner diameter of the test jig 81 is smaller than the outer diameter of the sensor 100 will be described.

[0040] (Test - Test Apparatus - Test Adapter) The test adapter 82 in Fig. 8 is the aforementioned test device. Specifically, it can be detachably attached to the tip side (+Z direction) of the test jig 81 in Fig. 6. For example, it is used to convert the diameter so that it is smaller than the diameter of the test jig 81. For example, it has a cylindrical shape, is made of metal, and has a hollow part that is continuous with the hollow part of the test jig 81 when attached. The size of this test adapter 82 is arbitrary. For example, as shown in Fig. 8, the case where the outer diameter of the test adapter 82 is smaller than the outer diameter of the sensor 100 will be described.

[0041] (Test - Specific Content) Next, the case of conducting the test without using the test adapter 82 and the case of conducting the test using the test adapter 82 will be described.

[0042] First, when conducting the test without using the test adapter 82, as shown in Fig. 7, the test jig 81 is brought into contact with the sensor 100, and a part of the sensor 100 (for example, the protection part 12, etc.) is accommodated in the hollow part of the test jig 81, and heat is applied from the hollow part side of the test jig 81. In this case, the control part of the sensor 100 detects it as a fire and outputs red light from the light - emitting part 15 in Fig. 4. Then, as described above, the red light is guided to the light - guiding part 111 and the protection part 12, and the entire light - guiding part 111 and protection part 12 will emit light. In this case, although a part of the light - guiding part 111 and the protection part 12 are hidden by the test jig 81 and cannot be visually recognized from the outside as shown in Fig. 7, since a part of the side part 111A on the side surface side of the outer cover 11 in the light - guiding part 111 is exposed, the red light emission of the side part 111A can be visually recognized. Therefore, the user can grasp the information related to the test by visually recognizing the red light emission of the side part 111A.

[0043] Next, when performing a test using the test adapter 82, as shown in FIG. 8, the test adapter 82 is brought into contact with the sensor 100 from the front side, and a part of the sensor 100 (for example, the protection part 12, etc.) is accommodated in the hollow part of the test adapter 82. Then, heat is applied from the hollow part side of the test adapter 82. In this case, after detecting the heat, the control unit of the sensor 100 outputs red light from the light emitting part 15 in FIG. 4. And as described above, the red light is guided to the light guide part 111 and the protection part 12, and the entire light guide part 111 and protection part 12 will emit light. In this case, although a part of the light guide part 111 and the protection part 12 are hidden by the test jig 81 and are not visible from the outside as shown in FIG. 8, a side part 111A which is a part of the side surface part side of the outer cover 11 in the light guide part 111, and a front side edge part 111B which is a part formed at the edge of the front part of the outer cover 11 in the light guide part 111 are exposed. Therefore, the red light emission of the side part 111A and the front side edge part 111B can be visually recognized. For this reason, the user can grasp the information regarding the test by visually recognizing the red light emission of the side part 111A and the front side edge part 111B.

[0044] (Effects of the Embodiment) As described above, according to this embodiment, at least a part of the display surface of the light guide part 111 which is the display means is exposed outside the test jig 81 or the test adapter 82 when at least a part of the outer cover 11 is covered by the test jig 81 or the test adapter 82 for performing the test on the sensor 100. For example, even when at least a part of the sensor 100 is covered by the test jig 81 or the test adapter 82, a part of the light guide part 111 can be made visible, so that it is possible to let the user grasp the information regarding the test.

[0045] Moreover, since the display means includes the side part 111A formed on the side surface part of the outer cover 11, for example, the display means can be visually recognized from any direction with respect to the sensor 100, so that it is possible to surely let the user grasp the information regarding the test.

[0046] Further, since the display means includes the front side edge portion 111B formed at the edge portion on the front surface of the outer cover 11, for example, the display means can be visually recognized even from directly below the sensor 100, so that information regarding the test can be reliably grasped.

[0047] Further, since the display means is a part of the light guide portion 111, for example, the degree of freedom in the installation position of the light emitting portion 15, which is the light source for the display means, can be improved, so that the degree of freedom in the design of the sensor 100 can be improved.

[0048] (Embodiment 2) Next, Embodiment 2 will be described. In this embodiment, the case where the display means is a thin portion will be described. Note that each configuration of this Embodiment 2 is the same as each configuration with the same name in Embodiment 1 unless otherwise specified.

[0049] (Configuration - Sensor) First, the configuration of the sensor according to this embodiment will be described. FIG. 9 is a perspective view of the sensor in the embodiment of the present invention, FIG. 10 is a plan view of the sensor, FIG. 11 is a side view of the sensor, and FIG. 12 is a cross-sectional view taken along line B - B of FIG. 10. The sensor 200 in each figure is a disaster prevention device, specifically, a heat sensor that detects heat. For example, it is attached to the mounting target 900 which is the ceiling surface via the mounting portion 201 of the sensor 200 in FIG. 11. As an example, it includes the outer cover 21, the protection portion 22, the prevention portion 23, the thermistor 24 in FIG. 12, and the light emitting portion 25 in FIG. 9.

[0050] (Configuration - Sensor - Outer Cover) The outer cover 21 in FIG. 9 covers at least a part of the components of the sensor 200. The specific type and configuration of this outer cover 21 are arbitrary. For example, it is a thing that blocks all or only a part of light, and also includes the thin portion 211 in FIG. 10.

[0051] The thin-walled portion 211 is a display means and is a portion of the outer cover 21 that is relatively thinner in thickness compared to other portions. The specific type and configuration of this thin-walled portion 211 are arbitrary. For example, it is a portion that is thin enough to allow at least a part of the irradiated light to pass through (that is, a portion that is thin enough to block only a part of the irradiated light), and is a portion formed integrally with other portions of the outer cover 21. Also, it extends from the front portion side (-Z direction) of the outer cover 21 to the side portion side (+X direction or -X direction) of the outer cover 21, and two of them are provided. Further, as shown in FIG. 10, it has a linear shape when viewed from the front portion side of the outer cover 21.

[0052] Note that "other portions of the outer cover 21" are a part of the outer cover 21, specifically, portions other than the thin-walled portion 211 of the outer cover 21. For example, they are portions having a thickness that blocks all of the irradiated light.

[0053] (Configuration - Sensor - Protection Portion) The protection portion 22 in FIG. 9 is the aforementioned detection element protection means. The specific type and configuration of this protection portion 22 are arbitrary. For example, it is formed on a part of the outer cover 21, and is formed of an arbitrary material in order to function as a light guide that guides light and emits light. Also, it is formed separately from the light-shielding portion of the outer cover 21, and allows light to pass from the inside to the outside of the outer cover 21. Further, the protection portion 22 protects, for example, the thermistor 24 in FIG. 12, and includes a frame portion 221, an opening portion 222 in FIG. 10, and a spectroscopic portion 223 in FIG. 12. Note that the configurations of the frame portion 221, the opening portion 222, and the spectroscopic portion 223 are the same as those of the components with the same names in Embodiment 1, so the description thereof is omitted.

[0054] (Configuration - Sensor - Prevention Portion, Thermistor, Light Emitting Portion) The configurations of the prevention portion 23 in FIG. 9, the thermistor 24 in FIG. 12, and the light emitting portion 25 are the same as those of the components with the same names in Embodiment 1, so the description thereof is omitted.

[0055] (Light emission) Next, the light emission by the sensor 200 configured as described above will be explained. FIG. 13 is a diagram illustrating the optical path in FIG. 12.

[0056] A control unit (not shown) of the sensor 200 in FIG. 13 outputs light from the light emitting unit 25. In this case, the light from the light emitting unit 25 is refracted, dispersed, or reflected by the spectroscopic unit 223 and is irradiated onto the entire thin portion 211 and guided to the entire protective unit 22 as shown in FIG. 13. Note that in FIG. 13, for convenience of explanation, only the optical path of the light from the light emitting unit 25 on the left side of the drawing is shown, but actually, light is also output from the light emitting unit 25 on the right side of the drawing, irradiated onto the entire thin portion 211, and guided to the entire protective unit 22. Then, the entire thin portion 211 and the protective unit 22 in FIG. 10 emit light.

[0057] (Test) Next, the test of the sensor 200 configured as described above will be explained. FIG. 14 is a diagram illustrating a test jig with respect to the cross-sectional view of FIG. 12, and FIG. 15 is a diagram illustrating a test adapter with respect to the cross-sectional view of FIG. 12. Here, the case of performing the test without using the test adapter 82 and the case of performing the test using the test adapter 82 will be explained.

[0058] First, when conducting the test without using the test adapter 82, as shown in FIG. 14, the test jig 81 is brought into contact with the sensor 200, and a part of the sensor 200 (for example, the protection part 22, etc.) is accommodated in the hollow part of the test jig 81. Then, heat is applied from the hollow part side of the test jig 81. In this case, the control part of the sensor 200 detects it as a fire and outputs red light from the light emitting part 25 in FIG. 13. And as described above, when the red light irradiates the entire thin part 211 and is also guided to the entire protection part 22, the entire thin part 211 and the protection part 22 will emit light. In this case, although a part of the thin part 211 and the protection part 22 are hidden by the test jig 81 and are not visible from the outside as shown in FIG. 14, since a side part 211A which is a part of the side surface part side of the outer cover 21 in the thin part 211 is exposed, the red light emission of the side part 211A can be visually recognized. Therefore, the user can grasp the information related to the test by visually recognizing the red light emission of the side part 211A.

[0059] Next, when conducting the test using the test adapter 82, as shown in FIG. 15, the test adapter 82 is brought into contact with the sensor 200, and a part of the sensor 200 (for example, the protection part 22, etc.) is accommodated in the hollow part of the test adapter 82. Then, heat is applied from the hollow part side of the test adapter 82. In this case, the control part of the sensor 200 detects it as a fire and outputs red light from the light emitting part 25 in FIG. 13. And as described above, when the entire thin part 211 is irradiated and the light is also guided to the entire protection part 22, the entire thin part 211 and the protection part 22 will emit light. In this case, although a part of the thin part 211 and the protection part 22 are hidden by the test jig 81 and are not visible from the outside as shown in FIG. 15, since a side part 211A which is a part of the side surface part side of the outer cover 21 in the thin part 211 and a front side edge part 211B which is a part formed at the edge of the front part of the outer cover 21 in the thin part 211 are exposed, the red light emission of the side part 211A and the front side edge part 211B can be visually recognized. Therefore, the user can grasp the information related to the test by visually recognizing the red light emission of the side part 211A and the front side edge part 211B.

[0060] (Effects of the Embodiment) As described above, according to this embodiment, since the display means is a part of the thin portion 211, for example, it is not necessary to provide other components for light emission, so the number of components can be reduced, and cost reduction can be achieved.

[0061] [Modifications to the Embodiment] Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Hereinafter, such modifications will be described.

[0062] (Regarding the Problems to be Solved and the Effects of the Invention) First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and may vary depending on the implementation environment and details of the configuration of the invention. It may solve only some of the above-described problems or exhibit only some of the above-described effects.

[0063] (Regarding Dispersion and Integration) Also, the above-described configuration is a functional concept, and it is not necessarily physically configured as shown in the drawings. That is, the specific form of dispersion and integration of each part is not limited to that shown in the drawings, and all or part of it can be functionally or physically dispersed or integrated in any unit.

[0064] (Regarding the Light Guide Portion and the Thin Portion) Also, in Embodiment 1, as shown in FIG. 2, the case where the light guide portion 111 has a linear shape when viewed from the front portion side of the outer cover 11 has been described, but it is not limited to this. For example, the light guide portion 111 may have a curved shape (for example, an S-shaped as a whole) when viewed from the front portion side of the outer cover 11. Note that the thin portion 211 in FIG. 10 of Embodiment 2 may also have a curved shape (for example, an S-shaped as a whole) in the same manner.

[0065] Also, in each embodiment, the case where two light guide parts and two thin-walled parts are provided has been described, but it is not limited thereto. For example, the light guide part and the thin-walled part may be omitted, or one may be provided, or three or more may be provided.

[0066] (Regarding the protruding part) Also, a protruding part may be provided for the sensor in each embodiment, and the protruding part may be used as a display means. FIG. 16 is a plan view of the sensor, and FIG. 17 is a view showing a test jig with respect to the C-C cross-sectional view of FIG. 16. The specific mounting method of the protruding part is arbitrary. For example, by extending the length in the X-axis direction of the light guide part 111 in FIG. 2 of Embodiment 1, as shown in FIG. 16, the tip of the light guide part 311 having the same configuration as the light guide part 111 may be configured as the protruding part 311A. In the case of the sensor 300 configured in this way, when the test jig 81 is provided as shown in FIG. 17, since the protruding part 311A, which is a part of the light guide part 311, is exposed from the test jig 81, when the protruding part 311A emits light by the light from the light emitting part during the test, the user can visually recognize the light emission. When configured in this way, since the protruding part 311A, which is the display means, protrudes from the side surface part of the outer cover of the sensor 300, for example, the protruding part 311A, which is the display means, can be surely visually recognized, so that information regarding the test can be surely grasped.

[0067] Also, for example, regarding the sensor 200 of Embodiment 2, after making the outer shape of the outer cover 21 have a protruding part similar to that of the sensor 300 in FIG. 16, by making the protruding part a thin-walled part, the protruding part may be configured as a display means.

[0068] Also, for example, by providing an indicator lamp (for example, a bullet-shaped indicator lamp similar to the conventional one) other than the light guide part or the thin-walled part on the side surface of the sensor, the like may be configured as a display means which is a protruding part.

[0069] (Regarding the features) Moreover, the configurations of the above-described embodiments and the features of the modified examples may be arbitrarily combined. For example, a thin portion may be provided on the outer cover 11 of the sensor 100 in FIG. 2 so that the thin portion emits light together with the light guide portion 111, or alternatively, a light guide portion may be provided on the outer cover 11 of the sensor 200 in FIG. 10 so that the light guide portion emits light together with the thin portion 211.
