  Then, by setting the switching operation body to the ON posture, the power supply state from the battery to the detection unit is turned on, the detection unit detects the detection target, and the switching operation body is set to the OFF posture. Thus, the power supply state from the battery to the detection unit is set to the OFF state, and the detection operation is stopped.

JP 2008-287382 A

  In the above detector, for example, before use at the time of shipment, the switching operation body is set to the OFF posture, and the power supply state from the power supply unit to the detection unit is set to the OFF state, thereby suppressing the consumption of the power supply unit (battery). doing. When the detector is used, the switching operation body is switched from the OFF posture to the ON posture, so that the detection operation is performed with the power supply state set to the ON state.

  However, if an unexpected operation such as an erroneous operation is performed on the device body while the detector is being used, the detector may not be used properly. Therefore, it is desired to take measures so that an unexpected operation is not performed during use of the detector.

  In view of this situation, a main problem of the present invention is to provide a detector that can prevent an unexpected operation such as an erroneous operation on the device body during use of the device.

  The first characteristic configuration of the present invention is a device body that includes a power supply unit and a detection unit that detects a detection target by supplying power from the power supply unit, and can be changed between an ON posture and an OFF posture. A switching operation body is provided to turn on the power supply state from the power supply unit to the detection unit in an attitude and turn the power supply state to an OFF state in an OFF attitude, and the ON posture of the switching operation body is The device is set in a posture that impairs an unspecified operation on the device body.

  According to this feature configuration, when the switching operation body is in the ON position, since the non-regulated operation on the device body is harmed, the switching operation body is in the ON position and the power supply state is in the ON state. When a user or the like performs some operation during use, if the operation is an out-of-specification operation different from the original operation on the device body, the out-of-specification operation becomes difficult. Therefore, the user or the like can feel a sense of incongruity and recognize that the operation is an unexpected operation, so that an unexpected operation can be prevented from being performed on the device main body.

  According to a second characteristic configuration of the present invention, the power supply unit and the detection unit are built in a case provided in the device main body, and an opening portion leading to the inside of the case is provided on an outer surface portion of the case. At the same time, the ON posture of the switching operation body is set to a posture that impairs the operation of the power supply unit or the detection unit through the opening as the non-regulated operation.

  According to this characteristic configuration, since the operation on the power supply unit or the detection unit can be performed through the opening, various operations such as maintenance work on the power supply unit or the detection unit can be performed. However, if an operation is performed on the power supply unit or the detection unit through the opening while the detector is being used, for example, power supply from the power supply unit to the detection unit is adversely affected, or detection of the detection target by the detection unit is adversely affected. May occur. Therefore, when the detector is in use, the operation through the opening to the power supply unit or the detection unit is an unspecified operation, and when the switching operation body is in the ON posture, the unspecified operation can be prevented from being performed.

  According to a third characteristic configuration of the present invention, a lid that closes the opening is provided, and the ON posture of the switching operation body is set to a posture that restricts the movement of the lid from the opening. It is in the point.

  According to this feature configuration, when the switching operation body is in the ON posture, the movement of the lid from the opening is limited, so that it is difficult to remove the lid from the opening, giving a clear discomfort to the user or the like. It is possible to reliably prevent the operation through the opening to the power supply unit or the detection unit.

  A fourth characteristic configuration of the present invention is that the opening is a power supply exchange port for exchanging the power supply unit.

  According to this characteristic configuration, the power supply unit can be exchanged through the power supply exchange port. Therefore, even if the power supply unit is consumed or deteriorated, it is only necessary to replace the power supply unit through the power supply exchange port. Easy to work. However, if the power supply unit is removed while the detector is in use, power cannot be supplied from the power supply unit to the detection unit, and the detection operation by the detection unit cannot be performed. Thus, when the switching operation body is in the ON posture, it is possible to appropriately prevent the detection operation by the detection unit from being performed by harming the operation through the power supply exchange port for the power supply unit.

  As shown in FIG. 2, in addition to the power supply unit 2 and the detection unit 3, the device main body 1 controls the detection operation of the detection unit 3 and the alarm operation according to the detection status, from the power supply unit 2 to the detection unit 3. A board 10 having a control circuit for performing various controls such as switching control of the power supply state, a speaker unit 11 for performing alarms and notifications such as sound, and various displays such as power ON / OFF and alarms A display unit 12 (for example, four display units) to perform and an operation unit 13 for stopping the alarm operation by the speaker unit 11 and the display unit 12 are provided.

  As shown in FIGS. 2 to 4, the side surface of the device main body 1 is provided with a switching operation body 14 that can change its posture between an ON posture and an OFF posture. As described above, the power switching unit 19 is provided which is moved by changing the posture of the switching operation body 14 and switches the power supply state from the power supply unit 2 to the detection unit 3 between the ON state and the OFF state.

  As shown in FIG. 5, the power switching unit 19 is movable between an ON position (a lower position in FIG. 5) and an OFF position (an upper position in FIG. 5). The power supply state from the power supply unit 2 to the detection unit 3 is set to the OFF state at the OFF position. As shown in FIGS. 3 and 4, the switching operation body 14 is configured to be detachable from the device main body 1, and the mounting posture with respect to the device main body 1 can be changed between an ON posture and an OFF posture. . The ON posture and the OFF posture of the switching operation body 14 are postures in which the switching operation body 14 is reversed forward and backward and attached to the device main body 1. As shown in FIG. As shown in FIG. 4, the main body 1 is mounted in a posture where the rear surface side of the switching operation body 14 is the front surface side of the device main body 1.

  As shown in FIG. 5, by setting the switching operation body 14 to the ON posture, the power switching unit 19 is moved to the ON position, and the power supply state from the power supply unit 2 to the detection unit 3 is set to the ON state. The detection operation in the unit 3 is performed. Conversely, by setting the switching operation body 14 to the OFF posture, the power switching unit 19 is moved to the OFF position, the power supply state from the power supply unit 2 to the detection unit 3 is turned off, and the detection unit 3 The detection operation is stopped. In FIG. 5, the state where the power switching unit 19 is moved from the OFF position to the ON position is shown on the left side, and the state where the power switching unit 19 is moved from the ON position to the OFF position is shown on the right side.

  The switching operation body 14 is disposed on a side surface portion (for example, a left side surface portion) of the device main body 1 (case 7) connected to the rear surface portion 1a of the device main body 1 (case 7) in an intersecting posture. As shown in FIGS. 3 to 5, the switching operation body 14 is inserted in the device main body 1 in a state of being mounted on the device main body 1 and has a posture extending in the front-rear direction of the device main body 1. A contact wall portion 17 that contacts the side surface portion of the device main body 1 and a knob 18 that extends from the contact wall portion 17 to the outer side of the device main body 1 are provided. The insertion portion 16 and the knob 18 are formed in a plate shape that is wide in the vertical direction of the device main body 1 and extends in the horizontal direction of the device main body 1, and the insertion portion 16, the knob 18 and the contact wall portion 17 intersect each other. It has become.

  As shown in FIG. 2, a mounting portion 15 for mounting the switching operation body 14 is formed on the side surface portion (for example, the left side surface portion) of the device main body 1. The mounting portion 15 is formed in a concave shape that is recessed inward of the device main body 1 with respect to the periphery thereof, and has a hole portion into which the insertion portion 16 of the switching operation body 14 is inserted. By fitting the switching operation body 14 into the mounting portion 15, the switching operation body 14 can be mounted on the device main body 1, and by pulling out the switching operation body 14 mounted on the mounting portion 15, the switching operation body 14 is removed from the device main body 1. 14 can be removed.

  As shown in FIG. 5, the insertion portion 16 in the switching operation body 14 is formed with a hook-shaped engagement portion 16 a at the center in the lateral width direction. In a state where the insertion portion 16 is inserted into the device main body 1, the engaging portion 16 a engages with an engaged portion (not shown) formed inside the device main body 1, and a switching operation body for the device main body 1. 14 is held in the ON or OFF position. Since the engaging portion 16a is arranged at the center in the lateral width direction of the insertion portion 16, when the switching operation body 14 is mounted in the ON posture or the OFF posture, the rattling becomes uniform in the lateral width direction of the insertion portion 16. I am doing so.

  The insertion unit 16 is provided with a moving action unit 16b that moves the power switching unit 19 between the ON position and the OFF position. The moving action portion 16b is configured by a notch groove portion having a pair of wall portions 16c and 16d that are opposed to each other at an interval, and one wall portion 16c of the pair of wall portions 16c and 16d is outside the device main body 1. It forms in the inclined wall part which makes the space | interval with the wall part 16d which opposes the near side narrow. As the insertion portion 16 of the switching operation body 14 is moved to the inward side of the device main body 1, the power switching portion 19 is pressed and guided by the inclined wall portion 16c to change from the ON position to the OFF position (see the right side in FIG. 5). ) Or from the OFF position to the ON position (see the left side in FIG. 5).

  The insertion portion 16 is formed with a hollow continuous portion 16e that is continuous with the hollow portion between the pair of wall portions 16c and 16d and extends to the rear side of the inclined wall portion 16c (the side away from the opposing wall portion 16d). ing. Accordingly, when the switching operation body 14 is mounted in the ON posture or the OFF posture, the inclined wall portion 16c is bent and deformed in accordance with the dimensional tolerance of the power switching portion 19, and the power switching portion 19 is changed by the inclined wall portion 16c. Proper press guidance is possible.

  As shown in FIGS. 3 and 4, the knob 18 in the switching operation body 14 is formed so as to extend outward from the center of the contact wall 17 in the vertical direction. And the knob | pick part 18 is bend | folded to the front side (the back side in the state of an OFF attitude | position) when the outer side edge part is an ON attitude | position, A finger | toe is hooked on this bending part, or it is bent with a finger The switching operation body 14 can be pulled out from the device main body 1 and the switching operation body 14 can be easily fitted into the device main body 1.

  In such a detector, the power supply unit 2 (battery) is set by setting the switching operation body 14 to the OFF posture and setting the power supply state from the power supply unit 2 to the detection unit 3 to the OFF state before use at the time of shipment or the like. The consumption of is suppressed. When using the detector, the switching operation body 14 is switched to the ON position to switch the power supply state from the power supply unit 2 to the detection unit 3 to the ON state, and the detection operation by the detection unit 3 is started. A monitoring mode is executed. In the monitoring mode, a detection operation is performed in which the detection unit 3 detects the presence status of a detection target such as smoke or CO gas in the air flowing in from the inlet 9, and the speaker unit according to the detection target presence status. 11 or the display unit 12 or the like, and the operation unit 13 is operated to release the alarm.

  If an unexpected operation such as an incorrect operation is performed on the device body 1 while the detector is in use, the detector may not be used properly. Therefore, in order to prevent an unexpected operation on the device main body 1 during use of the detector, as shown in FIG. 3, the ON posture of the switching operation body 14 causes an unspecified operation on the device main body 1. It is set in a damaging posture.

  The unspecified operation corresponds to an unexpected operation such as an operation that impedes execution of the monitoring mode when the monitoring mode is performed. In this embodiment, the operation through the battery exchange port 22 with respect to the power supply unit 2 is an unspecified operation. For example, when the switching operation body 14 is in the ON position, the power supply unit 2 (battery) is exchanged through the battery exchange port 22. This prevents the power supply unit 2 (battery) from being erroneously replaced during use of the detector.

  As shown in FIG. 3, the ON posture of the switching operation body 14 is a posture that covers a part of the lid 23 that closes the battery exchange port 22, and restricts the movement of the lid 23 from the battery exchange port 22. The posture is set. Covering the lid portion 23 with a part of the switching operation body 14 restricts the movement of the lid portion 23 to the outer side of the device main body 1. Therefore, when the switching operation body 14 is in the ON position, it is difficult to remove the lid 23 from the device main body 1 by the switching operation body 14. As a result, it is possible to give a sense of incongruity to the user, etc., and maintain the power supply state from the power supply unit 2 to the detection unit 3 in the ON state without accidentally removing the power supply unit 2 (battery). Can be appropriately executed, and the original function of the detector can be appropriately exhibited.

  As shown in FIGS. 3 to 5, the switching operation body 14 is formed in a wide shape in which the abutting wall portion 17 and the knob portion 18 are extended to one side in the vertical direction of the device body 1 with respect to the insertion portion 16. ing. The contact wall portion 17 and the knob portion 18 are in a posture extending upward from the device body 1 in the ON posture, as shown in the left side of FIGS. 3 and 5, and in the state shown on the right side in FIGS. 4 and 5. As described above, in the OFF posture, the posture extends to the lower side of the device main body 1.

  As shown in FIG. 3, the switching operation body 14 covers a part of the lid portion 23 with the abutting wall portion 17 and the knob portion 18 in a posture extending upward from the device main body 1 in the ON posture. The movement of the unit 23 to the outside of the device main body 1 is restricted. As described above, the switching operation body 14 itself is configured as an obstructing member that impairs an unspecified operation on the device main body 1. As shown in FIG. 4, when the switching operation body 14 is in the OFF posture, the contact wall portion 17 and the knob portion 18 are in a posture that extends downward from the device main body 1 and does not cover the lid portion 23. Therefore, when the switching operation body 14 is in the OFF posture, the lid 23 is removed from the device main body 1 by hooking a finger on the hook portion 23b of the lid 23 and moving the lid 23 to the outside of the device main body 1. Thus, the power supply unit 2 (battery) can be replaced.

  Further, in order to prevent forgetting to operate the switching operation body 14 to the ON position or an erroneous operation, as shown in FIG. 4, the OFF position of the switching operation body 14 causes at least a part of the inflow port 9 to be switched. The posture is set to cover with. By covering a part of the inlet 9 with the switching operation body 14, the amount of air flowing in from the inlet 9 is reduced, which adversely affects the detection operation in the detector 3. In this way, the OFF posture of the switching operation body 14 is set to a posture that affects the function of the device main body 1 executed when the power supply state is ON, and monitoring executed when the power supply state is ON. The function of the mode is harmed.

  When the switching operation body 14 is in the OFF posture, it is possible to visually give the user a sense of incongruity that the inflow port 9 is covered by the switching operation body 14. Can be easily recognized. Therefore, when the switching operation body 14 is in the OFF position, the user or the like reliably performs the operation of changing the posture to the ON position, prevents the switching operation body 14 from being forgotten or erroneous, and sets the monitoring mode appropriately. Can be executed.

  The posture change between the ON posture and the OFF posture of the switching operation body 14 is performed by inserting the switching operation body 14 into the mounting portion 15 by inverting the switching operation body 14 back and forth as shown in FIGS. The inflow port 9 is disposed on the rear side of the mounting portion 15 (the rear side of the switching operation body 14) in the front-rear direction of the device main body 1. Therefore, the switching operation body 14 extends as a contact wall portion 17 to the rear side in a crossing posture with respect to the insertion portion 16 and a first contact wall portion 17a extending in the front posture in a crossing posture with respect to the insertion portion 16. The second abutting wall portion 17b is provided, and the first abutting wall portion 17a is configured to have a longer length in the front-rear direction of the device body 1 than the second abutting wall portion 17b.

  As shown in FIG. 4, in the OFF posture, the long first contact wall portion 17a extends to the rear side of the device body 1, and a part of the inlet 9 is formed in the first contact wall portion 17a. Cover. On the other hand, as shown in FIG. 3, in the ON posture, the short second contact wall portion 17b extends to the rear side of the device body 1, and the second contact wall portion 17b reaches the inflow port 9. It does not reach and all the inflow ports 9 are open. As described above, the simple operation of changing the lengths of the first contact wall portion 17a and the second contact wall portion 17b makes it easy to simplify the configuration and forgets to operate the switching operation body 14 to the ON position. And operation mistakes can be prevented.

  As shown in FIG. 4, a mark 20 (OFF character) indicating an OFF state is attached to the front side of the mounting portion 15 on the side surface portion (for example, the left side surface portion) of the device body 1, and the switching operation body 14 is turned off. In the posture, this mark 20 is exposed to the outside. As shown in FIG. 3, when the switching operation body 14 is in the ON position, the mark 20 is covered and hidden by the abutting wall portion 17. Thus, only when the switching operation body 14 is in the OFF posture, the mark 20 is exposed from the outside, and the user or the like can easily recognize that the switching operation body 14 is in the OFF posture. In addition, since the length of the abutting wall portion 17 in the switching operation body 14 is made different, the mark 20 is attached to the part exposed to the outside only in the OFF posture, so that another member for hiding the mark 20 And there is no inconvenience such as an increase in the number of parts.

[Another embodiment]
(1) In the above-described embodiment, the ON posture of the switching operation body 14 is set to a posture that restricts the movement of the lid portion 23 from the battery exchange port 22. When the operation body 14 is in the ON posture, it is possible to set the posture in which at least a part of the battery exchange port 22 is closed by a part of the switching operation body 14. In addition, for example, an opening leading to the detection unit 3 is provided separately from the battery exchange port 22, and when the switching operation body 14 is in the ON posture, at least a part of the opening is a part of the switching operation body 14. It is also possible to set the posture to be closed. Thus, the ON posture of the switching operation body 14 can be set to a posture that impairs the operation on the power supply unit 2 or the detection unit 3 through the opening leading to the inside of the case.

(2) In the above embodiment, the operation through the battery exchange port 22 for the power supply unit 2 is illustrated as an unspecified operation. For example, various unexpected operations on the device body 1 as exemplified below are not specified. It can also be an operation.

  For example, if the user or the like touches the detection unit 3 directly or indirectly through some operation tool while using the detector, the sensitivity of the detection unit 3 is adversely affected, and the monitoring mode can be appropriately executed. The possibility of disappearing arises. Therefore, an operation in which the user or the like touches the detection unit 3 directly or indirectly is set as an off-regulation operation, and the ON position of the switching operation body 14 is changed, for example, the intrusion of a finger or an operation tool into the inside of the device body 1. It is also possible to set the posture to prevent.

  Further, if the cover 8 is removed from the case 7 during use of the detector and various devices and members built in the device main body 1 are touched, there is a possibility that the monitoring mode cannot be executed properly. Therefore, the operation of removing the cover 8 from the case 7 while the detector is in use can be set as an unspecified operation, and the ON posture of the switching operation body 14 can be set to a posture that impairs the removal of the cover 8.

  Here, the detector can be used not only as a home alarm device but also as various detectors such as an industrial detector. For example, in an industrial detector that stores various data such as history data and detection data during execution of the monitoring mode in the storage unit, if the reset switch is operated during execution of the monitoring mode, the data is stored. The data stored in the section will be reset. Therefore, the operation of the reset switch during the execution of the monitoring mode can be set as an unspecified operation, and the ON posture of the switching operation body 14 can be set to a posture that impairs the operation of the reset switch.

  Further, for example, in a portable detector that is stored in a container when not in use, or is connected to and placed on a charger or the like, the switching operation body 14 is set in the OFF position, the power supply state is set in the OFF state, By housing the detector in a charger or the like, consumption of the power supply unit 2 and the detection unit 3 is suppressed. Therefore, when the power supply state is in the ON state, the operation in which the detector is accommodated in the container, the charger, or the like is an unspecified operation, and the ON posture of the switching operation body 14 is set to be accommodated in the container, the charger, or the like. By setting the posture to cover the connector that connects the detector to the connector, the connection of the detector to the connector is obstructed, and the detector is accommodated in a container or a charger while the power supply state is ON. Can be prevented.

(3) In the above-described embodiment, when the switching operation body 14 is in the ON posture, the switching operation body 14 itself covers a part of the lid portion 23, but a covering member different from the switching operation body 14 is used. A part of the lid part 23 can be covered. For example, when the switching operation body 14 is in the ON posture, the covering member projects and moves to the outer surface portion of the device main body 1, and when the switching operation body 14 is in the OFF posture, the covering member retreats to the inner side of the device main body 1. A part of the lid 23 can be covered with a covering member.

  Further, as described in (2) above, even when the ON posture of the switching operation body 14 is set to a posture that impairs various unspecified operations on the device main body 1, as described above, it is different from the switching operation body 14. The obstructing member can harm the specified harmful operation.

(4) In the above embodiment, the switching operation body 14 may not be detachably provided to the device main body 1. For example, the switching operation body 14 can be freely rotated between a lock position and an unlock position, and the first position on the inner side and the second position on the outer side of the device main body 1 in a state of being rotated to the unlock position. It can also be freely movable. In this case, when it is rotated to the lock position at the first position, it is turned ON, and when it is rotated to the lock position at the second position, it is turned OFF.

  Further, as another example in which the switching operation body 14 is not detachable from the device body 1, the switching operation body 14 is rotated to the ON position and the OFF position at a position where the switching operation body 14 is slightly pulled out of the device body 1. It is possible to freely switch between the ON posture and the OFF posture by selecting any posture and pushing the switching operation body 14 toward the inside of the device main body 1.

(5) In the above embodiment, the switching operation body 14 is disposed on the left side, but may be on the right side, the upper side, or the lower side. Further, the shape of the device body 1 is not limited to a rectangular parallelepiped shape, and can be appropriately changed to various shapes.
