[0004] Although separate notification devices are provided for various purposes, notification devices for different purposes may have a common structure, and therefore it would be beneficial if a common notification device could be selectively used for multiple purposes.

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the dimensions, shapes, and ratios of the drawings may differ from those of the actual ones in order to facilitate understanding of the invention.

[0010] 1. Configuration FIG. 1 is a front view showing an example of a notification device 1 according to this embodiment. FIG. 2 is a right side view showing an example of the notification device 1. FIG. 3 is an exploded view of the notification device 1 shown in FIG. 2. The notification device 1 issues a notification in response to a user's operation. The notification device 1 can be selectively used for multiple purposes. The "purpose" here refers to the purpose of using the notification device 1. The purpose may include the function and type of the notification device 1, and the type of user. Here, the multiple purposes include use as an emergency notification button, use as a rescue button, and use as a fire notification button. The emergency notification button is used to report an abnormal event when the event occurs. The rescue button is used to call for rescue when rescue is needed. The fire notification button is used to report a fire when a fire occurs.

[0011] As shown in FIG. 3, the reporting device 1 comprises a housing 10, a push button switch 20, a cover 30, a lid 40, a circuit board 50, and a power supply 60. The housing 10 is box-shaped with an opening 11 and houses the push button switch 20, the circuit board 50, and the power supply 60. The push button switch 20 is provided on the circuit board 50 and is operated by a user to report an event. When pressed by a user, the push button switch 20 turns on and outputs an operation signal. The push button switch 20 is an example of an "operator" according to the present invention.

[0012] FIG. 4(a) is a front view showing an example of a plurality of covers 30. FIG. 4(b) is a view of the plurality of covers 30 shown in FIG. 4(a) as viewed from the direction of arrow I in the figure. The cover 30 shown in FIGS. 1 to 3 is one cover 30 selected from the plurality of covers 30. The plurality of covers 30 are used to select the use of the notification device 1. The plurality of covers 30 correspond to different predetermined uses. The plurality of covers 30 each have a different color so that the user can easily recognize the corresponding use. The user selects one cover 30 from the plurality of covers 30 that corresponds to the desired use and attaches it to the surface of the lid 40. The remaining covers 30 not selected by the user are not used. The cover 30 is an example of a "covering portion" according to the present invention.

[0013] As shown in FIGS. 1 and 3 , each cover 30 covers a central portion of the surface of the lid 40. That is, each cover 30 covers a portion of the front surface of the housing 10. As shown in FIG. 4( a), a button window 31 is formed in each cover 30 at a position overlapping the push button switch 20. The button window 31 is a hole for exposing the push button switch 20 to the outside. The button window 31 is large enough to accommodate the push button switch 20 and penetrates the cover 30 in the thickness direction. As shown in FIG. 4( b), two protrusions 32a and 32b (hereinafter collectively referred to as “protrusions 32”) are provided side by side on the back surface of each cover 30. The protrusions 32 are used to select the use of the notification device 1 and to attach the cover 30 to the lid 40. Each protrusion 32 has a hollow cylindrical shape and protrudes from the back surface of the cover 30.

[0014] The arrangement of the magnets 33 differs among the multiple covers 30. At least one of the multiple covers 30 has the magnet 33 provided on the protrusion 32a or 32b so that the multiple covers 30 have different arrangements of the magnets 33. Here, the multiple covers 30 include a cover 30-1 corresponding to the emergency call button, a cover 30-2 corresponding to the rescue button, and a cover 30-3 corresponding to the fire call button. All of the covers 30-1 to 30-3 may be provided to the user in advance, or any one of the covers 30-1 to 30-3 may be provided to the user in response to the user's request.

[0015] In the example shown in FIG. 4(b), no magnets 33 are provided on the protrusions 32a and 32b of the cover 30-1. The magnet 33 is provided on the protrusion 32a of the cover 30-2, but not on the protrusion 32b. The magnet 33 is not provided on the protrusion 32a of the cover 30-3, but is provided on the protrusion 32b. The magnets 33 may be provided by adhering them to the tip of the protrusion 32a or 32b, or by embedding them in the protrusion 32a or 32b. By providing the magnets 33 in this way, the covers 30-1 to 30-3 each have a different arrangement of the magnets 33.

[0016] FIG. 5 is a front view showing an example of the lid 40. The lid 40 opens and closes the opening 11 of the housing 10. A button window 41 is formed in the lid 40 at a position overlapping the push button switch 20. The button window 41 is a hole for exposing the push button switch 20 to the outside. The button window 41 is large enough to allow the push button switch 20 to pass through and penetrates the lid 40 in the thickness direction. Holes 42a and 42b (hereinafter also collectively referred to as "holes 42") are formed in the lid 40 at positions facing the protrusions 32a and 32b of the cover 30, respectively. The holes 42a and 42b are holes that allow the protrusions 32a and 32b of the cover 30 to protrude toward the inside of the housing 10. The holes 42a and 42b are large enough to allow the protrusions 32a and 32b to pass through and penetrate the lid 40 in the thickness direction. A protrusion 43 is provided on the back surface of the lid 40 between the button window 41 and the left end of the lid 40. Note that the position of the protrusion 43 shown in FIG. 5 is an example and is not limited to this. The protrusion 43 does not necessarily have to be provided adjacent to the button window 41, and may be provided at any position on the back surface of the lid 40 as long as it does not interfere with the push button switch 20. The protrusion 43 has a hollow cylindrical shape and protrudes from the back surface of the lid 40. As shown in FIG. 3, a magnet 44 is provided on the protrusion 43. The magnet 44 may be provided by adhering the magnet 44 to the tip of the protrusion 43 or by embedding the magnet 44 in the protrusion 43.

[0017] When attaching the cover 30 to the surface of the lid 40, the user inserts the protrusions 32a and 32b into the holes 42a and 42b of the lid 40, respectively. This fixes the cover 30 to the surface of the lid 40. When the user closes the lid 40 with the cover 30 attached, the protrusions 32a and 32b pass through the holes 42a and 42b, respectively, and protrude into the inside of the housing 10. Also, as shown in FIGS. 1 and 3, the push button switch 20 is exposed to the outside through the button window 41 of the lid 40 and the button window 31 of the cover 30. This allows the user to press the push button switch 20 without opening the lid 40.

[0018] FIG. 6 is a block diagram showing an example of the configuration on the board 50. In addition to the push button switch 20 described above, the board 50 is provided with a control unit 51, a memory unit 52, an input / output unit 53, an open / close detection unit 54, and magnet detection units 55a and 55b (hereinafter collectively referred to as "magnet detection unit 55"). These components are connected via a bus. The control unit 51 controls each unit of the notification device 1 and performs various processes. The control unit 51 includes one or more processors such as a CPU. The control and processes performed by the control unit 51 are realized by the processor executing a program stored in the memory unit 52. The memory unit 52 stores various data including a program for realizing the functions of the notification device 1. The memory unit 52 includes memories such as a RAM and an EEPROM. The input / output unit 53 inputs and outputs various signals. The input / output unit 53 is connected to an external device via a wired or wireless connection and outputs signals to the external device.

[0019] The open / close detector 54 detects whether the lid 40 is open or closed by detecting the magnet 44 provided on the protrusion 43 of the lid 40. When the open / close detector 54 detects the magnet 44, it detects that the lid 40 is closed. On the other hand, when the open / close detector 54 does not detect the magnet 44, it detects that the lid 40 is open. For example, a magnetic sensor is used as the open / close detector 54. Examples of magnetic sensors include a Hall IC, a magnet switch, and a reed switch. However, the magnetic sensor is not limited to these examples and may be any sensor that can detect the magnet 44.

[0020] The magnet detection unit 55 detects the magnet 33 attached to the protrusion 32 of the cover 30. For example, a magnetic sensor is used as the magnet detection unit 55. Examples of magnetic sensors include a Hall IC, a magnet switch, and a reed switch. However, the magnetic sensor is not limited to these examples, and any sensor that can detect the magnet 33 may be used.

[0021] FIG. 7 is a cross-sectional view of the reporting device 1 shown in FIG. 1 as viewed from the direction of arrows II-II. The open / close detector 54 is provided on the substrate 50 at a position where it can detect the magnet 44 provided on the protrusion 43. That is, the open / close detector 54 is provided at a position where its detection range includes the magnet 44 provided on the protrusion 43. If the open / close detector 54 has sensitivity directionality, the size of its detection range may vary depending on the direction. For example, as shown in FIG. 7, the open / close detector 54 may be provided at a position where its detection range includes at least the tip of the protrusion 43 and where it faces the protrusion 43. Alternatively, the open / close detector 54 may be provided at a position where its detection range includes at least the tip of the protrusion 43 and where it does not face the protrusion 43, for example, where it is adjacent to the protrusion 43 on the left and right.

[0022] FIG. 8 is a cross-sectional view of the reporting device 1 shown in FIG. 1 , taken along the line III-III. The magnet detector 55a is provided on the substrate 50 at a position where it can detect the magnet 33 attached to the protrusion 32a. The magnet detector 55b is provided on the substrate 50 at a position where it can detect the magnet 33 attached to the protrusion 32b. That is, the magnet detector 55a is provided at a position where its detection range includes the magnet 33 attached to the protrusion 32a. The magnet detector 55b is provided at a position where its detection range includes the magnet 33 attached to the protrusion 32b. However, the magnet detector 55a is provided at a position where it does not detect the magnet 33 attached to the protrusion 32b, i.e., where its detection range does not include the magnet 33 attached to the protrusion 32b. The magnet detector 55b is provided at a position where it does not detect the magnet 33 attached to the protrusion 32a, i.e., where its detection range does not include the magnet 33 attached to the protrusion 32a. When the magnet detection unit 55 has sensitivity directionality, the size of the detection range may vary depending on the direction. For example, the magnet detection units 55a and 51b may be provided in positions whose detection ranges include at least the tips of the protrusions 32a and 32b and face the protrusions 32a and 32b, as shown in Fig. 8. Alternatively, the magnet detection units 55a and 51b may be provided in positions whose detection ranges include at least the tips of the protrusions 32a and 32b and do not face the protrusions 32a and 32b.

[0023] 6, the control unit 51 functions as a switching unit 511 and a reporting unit 512. These functions are realized by the processor of the control unit 51 executing a program stored in the storage unit 52 to perform calculations or control each unit of the device itself.

[0024] The switching unit 511 switches to one of a plurality of operation modes corresponding to a plurality of uses in accordance with the detection result of the magnet detection unit 55. As described above, the arrangement of the magnets 33 in each of the plurality of covers 30 is different, and therefore the detection result of the magnet detection unit 55 varies depending on the cover 30 attached by the user. The switching unit 511 recognizes the cover 30 attached by the user based on the detection result of the magnet detection unit 55 and switches to an operation mode corresponding to the use corresponding to that cover 30. The use and operation mode corresponding to each cover 30 are predetermined. Here, the plurality of operation modes include a first operation mode corresponding to use as an emergency call button, a second operation mode corresponding to use as a rescue button, and a third operation mode corresponding to use as a fire call button. The switching unit 511 switches the operation mode on the condition that a predetermined operation is performed as a trigger for switching the operation mode, i.e., opening and closing the lid 40.

[0025] When the push button switch 20 is pressed, the notification unit 512 issues a notification according to the operation mode after switching by the switching unit 511. The notification unit 512 transmits to the external device a signal that differs depending on the operation mode after switching.

[0026] Returning to FIG. 3 , the power supply 60 is connected to each component provided on the substrate 50 via a power line and supplies power to each component. The power supply 60 includes a battery. In one example, the power supply 60 constantly supplies power to components other than the magnet detection unit 55 (including the open / close detection unit 54), while supplying power to the magnet detection unit 55 only while a process for switching the operating mode is being performed. Alternatively, the power supply 60 may constantly supply power to each component.

[0027] 2.Operation FIG. 9 is a flowchart showing an example of the operation of the notification device 1. The user switches the operation mode before starting to use the notification device 1. Note that in the initial state, the notification device 1 may operate in, for example, the first operation mode. The user first performs a predetermined operation that triggers the process of switching the operation mode, i.e., opening and then closing the lid 40. The user then selects a cover 30 corresponding to the desired purpose from among multiple covers 30 and attaches it to the surface of the lid 40.

[0028] For example, after opening the lid 40, the user attaches the cover 30 to the lid 40 and then closes the lid 40. At this time, the user attaches the cover 30-1 when using the notification device 1 as an emergency notification button, the cover 30-2 when using it as a rescue button, and the cover 30-3 when using it as a fire notification button.

[0029] When the user opens the lid 40, in step S11 the open / close detection unit 54 no longer detects the magnet 44, and therefore detects that the lid 40 is open (the determination in step S11 is YES). When the open state of the lid 40 is detected, the magnet detection unit 55 starts detection. Next, when the user attaches one of the covers 30-1 to 30-3 to the lid 40 and then closes the lid 40, in step S12 the open / close detection unit 54 detects the magnet 44 and therefore detects that the lid 40 is closed (the determination in step S12 is YES). In this way, when it is detected that the lid 40 has changed from an open state to a closed state, processing for switching the operating mode from step S13 onwards is started. Note that if the determination in step S11 is NO, the processing from step S12 onwards is not performed. If the determination in step S12 is NO, the determination in step S12 is repeated until the determination in step S12 is YES.

[0030] In step S13, the magnet detection unit 55 detects the magnet 33 provided on the cover 30. Note that if the magnet 33 is not provided on the cover 30, the magnet 33 is not detected. In step S14, the switching unit 511 selects an operation mode according to the detection result of the magnet 33 in step S13.

[0031] For example, if neither the magnet detector 55a nor the magnet detector 55b detects the magnet 33, this indicates that the user has attached the cover 30-1 shown in Fig. 4(b), which does not have the magnet 33 on either the protrusion 32a or 32b. In this case, this means that the user has selected the use as an emergency call button, so the switching unit 511 selects the first operation mode corresponding to the emergency call button.

[0032] If the magnet detection unit 55a detects the magnet 33 but the magnet detection unit 55b does not detect the magnet 33, this indicates that the user has attached the cover 30-2 in which the magnet 33 is provided only on the protrusion 32a as shown in Fig. 4(b). In this case, this means that the user has selected the use as a rescue button, so the switching unit 511 selects the second operation mode corresponding to the rescue button.

[0033] If the magnet detection unit 55a does not detect the magnet 33 but the magnet detection unit 55b does detect the magnet 33, this indicates that the user has attached the cover 30-3 in which the magnet 33 is provided only on the protrusion 32b shown in Fig. 4(b). In this case, this means that the user has selected the use as a fire alarm button, so the switching unit 511 selects the third operation mode corresponding to the fire alarm button.

[0034] When an operation mode is selected in this manner, the selected operation mode is stored in the memory unit 52. The operation mode stored in the memory unit 52 is used so that the notification device 1 operates in accordance with this operation mode when the power supply 60 is turned on again.

[0035] In step S15, the switching unit 511 switches to the operation mode selected in step S14. As a result, the reporting device 1 operates in accordance with the switched operation mode. When the process of switching the operation mode is completed in this manner, the detection of the magnet detection unit 55 is stopped.

[0036] When a situation arises in which a notification is necessary, the user presses the push button switch 20. When the user presses the push button switch 20, the push button switch 20 is turned on and an operation signal is supplied to the control unit 51. The notification unit 512 issues a notification according to the operation mode switched in step S15.

[0037] For example, if the operating mode after the switch is the first operating mode, the notification unit 512 transmits an emergency signal to the external device to notify the external device of an abnormal event. If the operating mode after the switch is the second operating mode, the notification unit 512 transmits a rescue signal to the external device to request rescue. If the operating mode after the switch is the third operating mode, the notification unit 512 transmits a fire signal to the external device to notify the external device of a fire. When a signal is transmitted from the notification device 1, for example, a person in charge at the external device takes action in response to the signal.

[0038] It should be noted that the cover 30 does not necessarily have to be attached. For example, if a user uses the notification device 1 as an emergency call button, the user may open and then close the lid 40 without attaching any of the multiple covers 30. In this case, as in the case where the cover 30-1 is attached, neither the magnet detector 55a nor the magnet detector 55b detects the magnet 33, and the device switches to the first operating mode corresponding to the emergency call button. In this case, the hole 42 is not used, and is preferably covered with a sticker or the like.

[0039] According to the embodiment described above, by attaching different covers 30 depending on the intended use, a common notification device 1 can be selectively used for multiple purposes, such as an emergency notification button, a rescue button, and a fire notification button. Furthermore, because the operation mode switching process is performed only when an explicit operation that triggers the operation mode switching is performed by the user, erroneous operation mode switching can be prevented. Furthermore, because the user can select the intended use of the notification device 1 by selecting and attaching the cover 30, the risk of erroneously selecting the intended use of the notification device 1 can be reduced. Furthermore, because the cover 30 is easily visible from the outside, the user can easily notice if the intended use of the notification device 1 is erroneously selected, compared to a configuration in which the intended use of the notification device 1 is selected using, for example, a switch provided inside the notification device 1. As a result, it is possible to prevent the notification device 1 from being operated with the intended use selected and transmitting an unintended signal when the push button switch 20 is actually pressed.

[0040] 3. Variations The present invention is not limited to the above-described embodiment. The above-described embodiment may be modified as in the following modified examples. Two or more of the following modified examples may be used in combination. The embodiment and one or more modified examples may be used in combination, or may be switched depending on the implementation.

[0041] In the above-described embodiment, the lid 40 does not necessarily have to be provided. For example, the cover 30 and the lid 40 may be integrally formed. Alternatively, the lid 40 may not be provided, and the cover 30 may cover at least a portion of the opening 11 of the housing 10. Even with this modified configuration, the common reporting device 1 can be selectively used for multiple purposes.

[0042] In the above-described embodiment, when at least one of a plurality of covers 30 is attached, the cover 30 may be provided with a protrusion 43 and a magnet 44 instead of the lid 40. In this case, a hole is formed in the lid 40 at a position overlapping with the protrusion 43 of the cover 30, allowing the protrusion 43 of the cover 30 to protrude inside the housing 10. When attaching the cover 30 to the surface of the lid 40, the user also inserts the protrusion 43 into the hole in the lid 40. As a result, the protrusion 43 passes through this hole and protrudes inside the housing 10. Even with the configuration according to this modification, it is possible to detect whether the lid 40 is open or closed.

[0043] In the above-described embodiment, the open / close detector 54 is not limited to one that uses magnetism to open and close the lid 40. For example, the open / close detector 54 may be a switch that is pressed by the protrusion 43 when the lid 40 is closed. Alternatively, the open / close detector 54 may be an optical sensor that uses light to detect whether the lid 40 is open or closed. This modified configuration can also detect whether the lid 40 is open or closed.

[0044] In the above-described embodiment, the reporting unit 512 is not limited to transmitting different signals depending on the operation mode. For example, the reporting unit 512 may transmit different types of signals or signals with different contents depending on the operation mode. Alternatively, the reporting unit 512 may transmit signals to different notification destinations depending on the operation mode. Even with the configuration according to this modification, different notifications can be made depending on the operation mode.

[0045] In the above-described embodiment, the use of the notification device 1 is not limited to an emergency button, a rescue button, or a fire button. For example, the notification device 1 may be used for any purpose as long as it transmits information in response to a user's operation, such as reporting an intruder or reporting an abnormality in a person's health.

[0046] In the above-described embodiment, the number of uses of the notification device 1 is not limited to three, but may be two, or may be four or more. To enable the use of the notification device 1 to be selected by the cover 30 attached to the notification device 1, the number of covers 30 and operation modes of the notification device 1 is preferably the same as the number of uses of the notification device 1. Furthermore, to enable each of the multiple covers 30 to have a different magnet 33 arrangement state, the number of protrusions 32 is preferably a number that can form the same number of magnet 33 arrangement state patterns as the number of uses of the notification device 1. The number of magnets 33 and the number of uses of the notification device 1 may or may not be the same. For example, when there are two magnets 33, four magnet 33 arrangement patterns can be formed, so the maximum number of uses of the notification device 1 is four. When there are three magnets 33, eight magnet 33 arrangement patterns can be formed, so the maximum number of uses of the notification device 1 is eight. Furthermore, in order to identify the same number of magnet 33 arrangement patterns as the number of uses of the reporting device 1, it is preferable that the number of magnet detection units 55 is the same as the number of protrusions 32. Even with the configuration according to this modification, a common reporting device 1 can be selectively used for multiple uses.

[0047] In the above-described embodiment, a detection switch, a rocker switch, or an operation image displayed on a touch panel may be used instead of the push button switch 20. The detection switch, rocker switch, and operation image are also examples of the "operator" according to the present invention. In short, the operator according to the present invention may be any type that accepts a user's operation. Even with the configuration according to this modification, a notification can be issued in response to a user's operation.

[0048] The present invention may be applied to the selection of the type of detector that detects an abnormality. Detectors that detect an abnormality may have a common structure even if the detector types are different. The detector has a detection unit that detects an abnormality in addition to the same configuration as the notification device 1 described above. However, the detector does not necessarily have to have the push button switch 20. The detector also has multiple protectors. These protectors play the same role as the multiple covers 30 described above.

[0049] The multiple protectors have different magnet 33 arrangements, similar to the multiple covers 30 described above. The user attaches a protector corresponding to the desired detector type to the detector. The detector switching unit 511 switches the operation mode to one of multiple operation modes corresponding to the multiple detector types, depending on the detection result of the magnet detection unit 55. The detector reporting unit 512 notifies an external device of the switched operation mode. The detector detection unit operates according to the switched operation mode.

[0050] For example, consider a case where a common detector can be selectively used as a smoke fire detection sensor and a heat fire detection sensor. When a user wants to use the detector as a smoke fire detection sensor, the user attaches a protector compatible with the smoke fire detection sensor. When the detector's switching unit 511 recognizes that a smoke fire detection sensor has been attached based on the position of the protector's magnet 33, it switches to an operation mode compatible with the smoke fire detection sensor. The detector's reporting unit 512 notifies an external device of the operation mode after switching. When the detector is switched to an operation mode compatible with the smoke fire detection sensor, for example, a program is executed in the detector to operate as a smoke fire detection sensor. The detector's detection unit detects a fire according to this program. As a result, the detector operates as a smoke fire detection sensor.
