Description

The present invention relates to an item movement detection device that can detect when an item such as an AED has been moved from a storage location, etc.

Conventionally, AED storage devices that can store and keep an automated external defibrillator (AED) in preparation for sudden illness, etc., are widely known.

For example, Patent Document 1 discloses an example of such an AED storage device, which includes a communication means for communicating with a management device connected via a communication line, a first sensor for detecting the removal of an emergency device (AED), a second sensor for detecting an abnormal state of the emergency device by non-contactly detecting the display or a change in display of a display means that the emergency device has for displaying the operating state of the emergency device, and a control means for monitoring the detection state of the first and second sensors and notifying the management device of the removal of the emergency device or the detection of the abnormal state of the emergency device via the communication means.

Patent Document 2 also discloses an emergency response vending machine that stores an automated external defibrillator (AED) inside a storage box with a door that can be opened from the front, and has microswitches on the door and the bottom of the storage box, and is equipped with an emergency display mechanism that detects the opening of the door and the removal of the automated external defibrillator using the microswitch to control the lighting of an alarm lamp, the sounding of an alarm buzzer, and the display of emergency measures, and an emergency reporting mechanism that, upon detection of the removal of the automated external defibrillator, sends an emergency report to an external management device requesting the dispatch of an ambulance.

Patent document 3 discloses an automatic external defibrillator storage device that includes a removal detection means for detecting when a stored automatic external defibrillator (AED) has been removed, and a notification means for notifying an administrator and a management center that manages the automatic external defibrillator storage device when the removal detection means detects that the automatic external defibrillator has been removed.

Patent No. 4828892 Utility Model Registration No. 3125304 JP 2009-22701 A

However, conventional AED storage devices are designed to detect the removal of an AED by detecting the movement of the AED itself using various sensors (e.g., optical sensors, weight sensors) or microswitches, which poses the problem that the AED must be stored in a fixed location, limiting the freedom of where the AED can be stored.

In addition, there was a problem that the AED could be falsely detected as having been taken out if even a slight external force such as a shock or vibration was applied to the AED, and conversely, there was a problem that the AED could not be detected as having been taken out depending on the way it was taken out.

The present invention has been made to solve these problems in the past, and aims to provide an object movement detection device that allows for greater freedom in the storage location of objects whose movement is to be detected, and can increase the accuracy of object movement detection while preventing erroneous detection of object movement.

The item movement detection device of the present invention comprises a holder, a key that can be attached to the holder, and a switch that can detect when the key has been removed from the holder. The holder or the key is attached directly or indirectly to an item, and the switch detects when the key has been removed from the holder, thereby detecting the movement of the item. The item movement detection device is characterized in that the switch can detect the movement of the item when the key attached to the holder is pulled out in a first direction along the switch, and when the key attached to the holder is pulled out in a second direction away from the switch.

The item movement detection device according to the present invention can provide the excellent effect of increasing the degree of freedom in the storage location of the item whose movement is to be detected, and increasing the accuracy of detecting the movement of the item while preventing erroneous detection of the movement of the item.

The side wall 12b has two screw holes 12b1 formed in two locations corresponding to the screw insertion holes 14a1 of the lid 14, and screws for fixing the lid 14 to the main body 12 can be attached to these screw holes 12b1.

The pin contact portion 12c is a portion that is extended in the thickness direction from the corner of the base portion 12a as its base end, and is the portion that contacts the head portion 18b of the pin 18 when the pin 18 is attached (inserted) into the holder 16.

The pin abutment portion 12c has a curved recess 12c1 that has a shape complementary to the head 18b of the pin 18, and when the pin 18 is attached (inserted) into the holder 16, the head 18b of the pin 18 can be accommodated in this curved recess 12c1. The pin abutment portion 12c also has a screw hole 12c2 formed at one location corresponding to the screw insertion hole 14a1 of the lid 14, and a screw for fixing the lid 14 or the clip 24 to the main body 12 can be attached to this screw hole 12c2.

The switch fixing part 12d is a rod-shaped part that extends in the thickness direction from the bottom of the base part 12a. The switch fixing part 12d is composed of two rod-shaped bodies, and the switch 20 is fixed to this switch fixing part 12d while being housed in the inner space of the main body 12.

The cable insertion portion 12e is a portion between the side wall 12b and the pin abutment portion 12c, which is extended in the thickness direction from the bottom surface of the base portion 12a as a base end. The cable insertion portion 12e has an insertion hole 12e1 through which the cable 22 electrically connected to the switch 20 can be inserted.

The first engagement recess 12f is a circular recess formed on the bottom surface of the base portion 12a, and has a shape complementary to the first engagement protrusion 18d (see FIG. 2(b)) on the body side of the pin 18. The first pin engagement recess 12f is a hemispherical recess formed by equally dividing a nearly perfect sphere in two, and can engage (fit) with the first engagement protrusion 18d on the body side of the pin 18, which is made up of a protrusion of the same hemispherical shape.

The second engagement recess 12g is an oval recess formed on the bottom surface of the base portion 12a, and has a shape complementary to the main body side second engagement protrusion 18e of the pin 18 (see FIG. 2(b)). The second engagement recess 12g is a semi-ellipsoidal recess in which a quarter sphere (a sphere divided into four equal parts by two planes including its center) is arranged on both ends of a semi-cylinder formed by equally dividing a nearly circular cylinder in the longitudinal direction, and can engage (fit) with the main body side second engagement protrusion 18e of the pin 18, which is formed of a protrusion of the same semi-ellipsoidal shape.

<Holder/Cover>
Next, the lid 14 of the holder 16 will be described.

As shown in FIG. 2(b) and other figures, the cover 14 is composed of a plate-shaped base portion 14a, a cable holder 14b that extends in the thickness direction from the bottom surface of the base portion 14a, and a third engagement recess 14c and a fourth engagement recess 14d that protrude from the bottom surface of the base portion 14a.

The base portion 14a is a rectangular plate-like portion that serves as the base (foundation) of the lid body 14. Screw insertion holes 14a1 are formed at each of the three corners of the base portion 14a, and screws for fixing the lid body 14 and the clip 24 to the main body 12 can be attached to these screw holes 14a1.

The cable holder 14b is a portion that is extended in the thickness direction from one of the short sides of the base portion 14a as a base end, and is formed at a location that corresponds to the cable insertion portion 12e (see FIG. 3(b)) of the main body 12. When the cover 14 is attached to the main body 12, the cable holder 14b of the cover 14 is configured to cover the insertion hole 12e1 of the cable insertion portion 12e of the main body 12, so that the cable 22 is supported by being sandwiched between the main body 12 and the cover 14.

The third engagement recess 14c is a circular recess formed on the bottom surface of the base portion 14a, and has a shape complementary to the first engagement protrusion 18f (see FIG. 3(b)) on the lid side of the pin 18. The third engagement recess 14c is a hemispherical recess formed by dividing a nearly perfect sphere into two equal parts, and can engage (fit) with the first engagement protrusion 18f on the lid side of the pin 18, which is made up of the same hemispherical protrusion.

The fourth engagement recess 14d is an oval recess formed on the bottom surface of the base portion 14a, and has a shape complementary to the second lid-side engagement portion 18g of the pin 18 (see FIG. 3(b)). The fourth engagement recess 14d is a semi-ellipsoid recess in which a quarter sphere (a sphere divided into four equal parts by two planes including its center) is arranged on both ends of a semi-cylinder formed by equally dividing a nearly circular cylinder in the longitudinal direction, and can engage (fit) with the second lid-side engagement protrusion 18g of the pin 18, which is formed of a protrusion of the same semi-ellipsoid shape.

<Pin>
Next, the pin 18 will be described with reference to FIGS.

The pin 18 is made up of a rectangular parallelepiped gripping portion 18a, a curved head 18b extending from one side of the gripping portion 18b in the longitudinal direction, and a string hole 18c formed at a corner of the gripping portion 18a. In this example, the pin 18 is made of a plastic (polycarbonate) member.

The material of the "key (pin)" according to the present invention is not particularly limited, and may be, for example, a thermoplastic resin other than polycarbonate, or a metal such as stainless steel or aluminum, resin, wood, etc.

The gripping portion 18a is a rectangular parallelepiped-shaped part that serves as the base (foundation) of the pin 18.

As shown in FIG. 2(b) etc., a first body-side engaging protrusion 18d and a second body-side engaging protrusion 18e are formed on one thickness-wise side of the gripping portion 18a.

The first engagement protrusion 18d on the main body side is a circular protrusion formed on one side of the gripping portion 18a, and has a shape complementary to the first engagement recess 12f (see FIG. 3(b)) of the main body 12 of the holder 16. The first engagement protrusion 18d on the main body side is a hemispherical protrusion formed by dividing a nearly perfect sphere into two equal parts, and can engage (fit) with the first engagement recess 12f of the holder 16, which is formed of the same hemispherical recess.

The second engagement protrusion 18e on the main body side is an oval-shaped protrusion formed on one side surface of the gripping portion 18a, and has a shape complementary to the second engagement recess 12g (see FIG. 3(b)) of the main body 12 of the holder 16. The second engagement protrusion 18e on the main body side is a semi-ellipsoidal protrusion in which a quarter sphere (a sphere divided into four equal parts by two planes including its center) is arranged on both ends of a semi-cylinder formed by equally dividing a nearly circular cylinder in half in the longitudinal direction, and can engage (fit) with the second engagement recess 12g of the holder 16, which is a recess of the same semi-ellipsoidal shape.

On the other side of the gripping portion 18a in the thickness direction, as shown in FIG. 3(b) etc., a first lid-side engaging protrusion 18f and a second lid-side engaging protrusion 18g are formed.

The first engaging protrusion 18f on the lid side is a circular protrusion formed on the other side surface of the gripping portion 18a, and has a shape complementary to the third engaging recess 14c (see FIG. 2(b)) of the lid 14 of the holder 16. The first engaging protrusion 18f on the lid side is a hemispherical protrusion formed by dividing a nearly perfect sphere into two equal parts, and can engage (fit) with the third engaging recess 14c of the holder 16, which is formed of the same hemispherical recess.

The second lid-side engaging protrusion 18g is an oval-shaped protrusion formed on the other side of the gripping portion 18a, and has a shape complementary to the fourth engaging recess 14d (see FIG. 2(b)) of the lid 14 of the holder 16. The second lid-side engaging protrusion 18g is a semi-ellipsoidal protrusion in which a quarter sphere (a sphere divided into four equal parts by two planes including its center) is arranged on both ends of a semi-cylinder formed by equally dividing a nearly circular cylinder in half in the longitudinal direction, and can engage (fit) with the fourth engaging recess 14d of the holder 16, which is a recess of the same semi-ellipsoidal shape.

The pin 18 (key) in this example has a first engagement portion (main body side second engagement protrusion 18e shown in FIG. 2(b) and lid side second engagement protrusion 18g shown in FIG. 3(b)) that extends linearly in a first direction (in this example, the longitudinal direction of the pin 18), and the holder 16 has an engagement portion (second engagement recess 12g shown in FIG. 3(b) and fourth engagement recess 14d shown in FIG. 2(b)) that can engage with the first engagement portion of the pin 18 (key). Therefore, when the pin 18 (key) is pulled out in the first direction along the switch 20, the pin 18 (key) can be guided linearly along the first engagement portion extending in the first direction, allowing the key to be pulled out smoothly and reliably, and improving the accuracy of detecting the movement of an item.

The pin 18 (key) has a second circular engagement portion (first main body-side engagement protrusion 18d shown in FIG. 2(b) and first lid-side engagement protrusion 18f shown in FIG. 3(b)) that is different in shape from the first engagement portion, and the holder 16 has an engagement portion (first engagement recess 12f shown in FIG. 3(b) and third engagement recess 14c shown in FIG. 2(b)) that can engage with the second engagement portion of the pin 18 (key). This allows the pin 18 (key) and holder 16 to be securely engaged with each other by the first engagement portion and the second engagement portion, preventing erroneous detection of the movement of an item, improving the feel of operation (feel of wearing) when the key is attached to the holder, and allowing the key to be securely set in the holder.

<Switch>
Next, the switch 20 will be described with reference to FIG.

Figure 4 (a) shows the pin 18 attached to the holder 16, and (b) shows the pin 18 attached to the holder 16 after being pulled out linearly in the X direction.

The switch 20 is a detection means capable of detecting that the pin 18 has been removed from the holder 16, and in this example, a microswitch with a b-contact is applied. Note that the "switch" according to the present invention is not limited to a microswitch, and may be other detection means such as a magnetic sensor. Furthermore, the contact type of the "switch" is not limited to a b-contact, and may be, for example, an a-contact or a c-contact.

The switch 20 is fixed to the switch fixing portion 12d of the main body 12 while being accommodated in the inner space of the main body 12 of the holder 16.

The switch 20 is composed of an actuator section 20a for transmitting external forces and movements to the internal mechanism, an internal mechanism (not shown) consisting of a movable spring and contact section, etc., and a terminal section (not shown) that is electrically connected to the connector 22a of the cable 22.

As shown in FIG. 4(a), when the pin 18 is inserted into the body 12 of the holder 16, the actuator part 20a is pressed in the direction toward the body of the switch 20 against the biasing force of the leaf spring as the pin 18 advances, and when an external force is applied to the internal mechanism via the actuator part 20a, the movable contacts and fixed contacts of the internal mechanism change from a contacting state to a non-contacting state, and the switch 20 turns off.

On the other hand, as shown in FIG. 4(b), when the pin 18 is pulled out of the body 12 of the holder 16, the actuator part 20a moves away from the body of the switch 20 due to the biasing force of the leaf spring as the pin 18 retreats, and when external force is no longer applied to the internal mechanism via the actuator part 20a, the movable contact and fixed contact of the internal mechanism change from a non-contact state to a contact state, and the switch 20 turns on.

<Cable>
Next, the cable 22 will be described with reference to FIG.

The cable 22 is a connection means for electrically connecting the switch 20 to an external device (not shown) (e.g., a remote monitoring terminal device).

One end of the cable 22 is electrically connected to a terminal portion (not shown) of the switch 20 via a connector 22a crimped to one end of the cable 22, and then inserted into the insertion hole 12e1 of the holder 16 and pulled out from inside the body 12 of the holder 16 to outside the body 12 of the holder 16.

The other end of the cable 22 is connected to a remote monitoring terminal device (not shown) in this example via a connector 22a crimped to the other end of the cable 22.

As shown in FIG. 4(b), when the pin 18 is pulled out of the body 12 of the holder 16 and the switch 20 changes from an off state to an on state, a control signal notifying the remote monitoring terminal device (not shown) that the pin 18 has been pulled out of the holder 16 is output via the cable 22.

<Operation of the item movement detection device>
Next, the operation of the article movement detection device 10 will be described with reference to FIGS.

Figure 5 (a) shows the pin 18 attached to the holder 16, and (b) shows the pin 18 attached to the holder 16 rotated in the Y direction and pulled out.

First, a user of the item movement detection device 10 attaches the holder 16 to a container (e.g., an AED container bag) that contains an item (e.g., an AED) whose movement is to be detected, using a clip 24 (see Figure 1) or the like.

Next, the user of the item movement detection device 10 secures the pin 18 to a location of their choice (for example, a post near the storage location of the AED) using a string 26 or the like, and then attaches (inserts) the pin 18 into the holder 16. This puts the item movement detection device 10 into a detection standby state (the state shown in Figures 4(a) and 5(a)) in which it can detect the movement (removal) of an item (in this example, an AED).

When the item (AED) is moved (taken out) in this detection standby state, as shown in FIG. 4(b), the pin 18 attached to the holder 16 is pulled out linearly in the X direction (first direction, e.g., horizontal direction) along the switch 20, and as the pin 18 is withdrawn, the actuator part 20a moves in a direction away from the main body of the switch 20, and when the switch 20 is in the ON state (a state in which the movable contact and fixed contact of the internal mechanism of the switch 20 are in contact), a control signal is output from the cable 22 to an external remote monitoring terminal device to notify the external remote monitoring terminal device that the pin 18 has been pulled out of the holder 16.

In addition, when the item (AED) is moved (taken out) in the detection standby state, as shown in FIG. 5(b), the pin 18 attached to the holder 16 is rotated in the Y direction (second direction, e.g., vertical direction) away from the switch 20 and pulled out, and as the pin 18 is withdrawn, the actuator part 20a moves in a direction away from the main body of the switch 20, and when the switch 20 is in the ON state (a state in which the movable contact and the fixed contact of the internal mechanism of the switch 20 are in contact), a control signal is output from the cable 22 to an external remote monitoring terminal device to notify the external remote monitoring terminal device that the pin 18 has been pulled out of the holder 16.

The item movement detection device 10 of this example can detect the movement of an item (e.g., an AED) not only when the pin 18 (key) is pulled out in a first direction (X direction) along the switch 20, but also when the pin 18 (key) is pulled out in a second direction (Y direction) away from the switch 20. Therefore, as long as the pull-out angle of the pin 18 relative to the holder 16 is within 90 degrees, the pin 18 can be pulled out of the holder 16, which increases the freedom of the storage location of the item whose movement is to be detected, and improves the detection accuracy of the item movement while preventing erroneous detection of the item movement.

In addition, the pin 18 (key) has a curved head 18b (curved portion), and when the pin 18 (key) attached to the holder 16 is pulled out in the second direction (Y direction), the pin 18 (key) rotates around the head 18b (curved portion) as a base point. Therefore, when the pin 18 (key) is pulled out in the second direction (Y direction) away from the switch 20, the pin 18 (key) can be smoothly moved (rotated) in the second direction (Y direction). This allows the key to be pulled out smoothly and reliably, and improves the accuracy of detecting the movement of an item.

The pin 18 (key) has a string hole (string hole 18c shown in Figs. 4 and 5) through which a string (string 26 shown in Fig. 5) can be inserted. When the string 26 is pulled in a first direction (X direction) as shown in Fig. 4(b), the pin 18 (key) attached to the holder 16 is pulled out linearly in the first direction. When the string 26 is pulled in a second direction (Y direction) as shown in Fig. 5(b), the pin 18 (key) attached to the holder 16 is rotated in the second direction and pulled out. This allows the key to be pulled out via the string, which increases the freedom of installation location of the item movement detection device, and allows the key to be pulled out more smoothly and reliably than before, improving the accuracy of detecting the movement of items.

<Modification of the object movement detection device>
In this example, an example of detecting the movement (removal) of an AED has been described, but the "item" according to the present invention is not limited to an AED, and may be other items such as a personal computer, a suitcase, or a bag.

In addition, in this example, the holder 16 is attached to a container (in this example, an AED container bag) that contains an item (in this example, an AED) whose movement is to be detected using the clip 24, but the "holder" according to the present invention may be attached directly to the "item" whose movement is to be detected, or may be attached indirectly to a container (for example, a bag, bag, box, case, etc.) that contains an item whose movement is to be detected.

In addition, instead of the "holder" of the present invention, the "key (pin)" of the present invention may be attached to an item. In this case, the "key (pin)" of the present invention may be attached directly to the "item" whose movement is to be detected, or indirectly to a container (e.g., a bag, pouch, box, case, etc.) that contains the item whose movement is to be detected.

Therefore, in the previous example of the AED, the pin 18 can be fixed to a container (e.g., an AED container bag) that contains an item (e.g., an AED) whose movement is to be detected, using a string-like body 26, and the holder 16 can be attached to any location (e.g., a pole near the storage location of the AED) using a clip 24 or the like.

In addition, in this example, the holder 16 is attached using the clip 24, but the manner of attachment of the "holder" according to the present invention is not particularly limited. For example, the "holder" may be attached directly to an item or contents, or may be attached to an item or contents using Velcro (registered trademark), screws, etc.

Although an example of fixing the pin 18 using a string-like body 26 has been described, the manner of attachment of the "key (pin)" according to the present invention is not particularly limited. For example, the "key (pin)" may be attached directly to an item or contents, or may be attached to an item or contents using Velcro or screws, etc.

Although an example has been shown in which the pin 18 is pulled out of the holder 16 via the string-like body 26, the method of pulling out (removing) the "key (pin)" of the present invention from the "holder" is not particularly limited. For example, the "key (pin)" may be pulled out directly, or the "key (pin)" may be pulled out relatively from the "holder" by pulling the "holder" away from the "key (pin)" while the "key (pin)" is fixed.

<Item movement detection device/Summary>
As described above, the article movement detection device according to this embodiment (for example, the article movement detection device 10 shown in FIG. 1) includes a holder (for example, the holder 16 shown in FIG. 1), a key that can be attached to the holder (for example, the pin 18 shown in FIG. 1), and a switch that can detect that the key has been removed from the holder (for example, the switch 20 shown in FIGS. 4(a) and 4(b)). The holder or the key is directly or indirectly attached to an article (for example, an AED, a personal computer, a suitcase, a bag, etc.), and the switch detects whether the key has been removed from the holder. an article movement detection device capable of detecting the movement of an article by detecting that the key has been removed from a holder, wherein the switch is capable of detecting the movement of the article when the key attached to the holder is pulled out in a first direction (e.g., the direction indicated by the symbol X in FIG. 4(b)) along the switch, and when the key attached to the holder is pulled out in a second direction (e.g., the direction indicated by the symbol Y in FIG. 5(b)) away from the switch.

The item movement detection device according to this embodiment can detect the movement of an item not only when the key is pulled out in a first direction along the switch, but also when the key is pulled out in a second direction away from the switch. This allows for greater freedom in the storage location of the item whose movement is to be detected, and increases the accuracy of detecting the movement of the item while preventing erroneous detection of the movement of the item.

The key may also have a curved surface (e.g., head 18b shown in Fig. 3(b) and Fig. 5(b)), and when the key attached to the holder is pulled out in the second direction, the key may rotate around the curved surface.

With this configuration, when the key is pulled out in the second direction away from the switch, the key can be smoothly moved (rotated) in the second direction, allowing the key to be pulled out smoothly and reliably, and improving the accuracy of detecting the movement of an item.

The key may have a first engagement portion (e.g., the second engagement protrusion 18e on the main body side shown in FIG. 2(b) and the second engagement protrusion 18g on the cover side shown in FIG. 3(b)) that extends linearly in the first direction, and the holder may have an engagement portion that can engage with the first engagement portion of the key (e.g., the second engagement recess 12g shown in FIG. 3(b) and the fourth engagement recess 14d shown in FIG. 2(b)).

With this configuration, when the key is pulled out in the first direction along the switch, the key can be guided linearly along the first engagement portion extending in the first direction, allowing the key to be pulled out smoothly and reliably, and improving the accuracy of detecting the movement of an item.

The key may have a second circular engagement portion (e.g., first main body-side engagement protrusion 18d shown in FIG. 2(b) and first lid-side engagement protrusion 18f shown in FIG. 3(b)) that is different in shape from the first engagement portion, and the holder may have an engagement portion that can engage with the second engagement portion of the key (e.g., first engagement recess 12f shown in FIG. 3(b) and third engagement recess 14c shown in FIG. 2(b)).

With this configuration, the key and holder can be securely engaged by the first and second engagement parts, which prevents erroneous detection of the movement of an item, improves the feel of the key when it is attached to the holder (fitting feel), and allows the key to be securely set in the holder.

Furthermore, if the key has a first surface (e.g., the surface shown in FIG. 2(b)) and a second surface (e.g., the surface shown in FIG. 3(b)) that is the opposite surface to the first surface, and the first engagement portion and the second engagement portion are formed on both the first surface and the second surface, the key and the holder can be engaged more reliably, and the operability (fitting feel) when the key is attached to the holder can be further improved.

The key may also have a string hole (e.g., string hole 18c shown in Figures 4 and 5) through which a string-like body (e.g., string-like body 26 shown in Figures 4 and 5) can be inserted, and when the string-like body is pulled in the first direction (e.g., the direction indicated by symbol X in Figure 4(b)), the key attached to the holder is pulled out linearly in the first direction, and when the string-like body is pulled in the second direction (e.g., the direction indicated by symbol Y in Figure 5(b)), the key attached to the holder is rotated in the second direction and pulled out.

With this configuration, the key can be removed via the string, allowing for greater freedom in where the item movement detection device can be installed, and the key can be removed more smoothly and reliably than before, improving the accuracy of detecting the movement of items.

The item may also be an AED.

With this configuration, if an AED is removed from a storage location, etc., it can be reliably detected and processing such as notifying the outside that the AED has been removed can be performed.

The configuration of the item movement detection device according to the present invention is not limited to the configuration of the item movement detection device 10 according to the above embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

Therefore, for example, the use of the "item movement detection device" according to the present invention is not particularly limited, and may be used for the purpose of detecting when an item has been taken by a legitimate user, or for the purpose of detecting when an item has been taken without permission (stolen) by someone other than the owner of the item, or for the purpose of detecting when an item has been moved due to an unavoidable disaster such as an earthquake or flood.

In addition, the "first direction" according to the present invention is not limited to the longitudinal direction of the switch, but may be the lateral direction of the switch, or may be the "longitudinal direction of the key" or the "lateral direction of the key" instead of the "direction along the switch."

The "second direction" according to the present invention may be any direction in which the key attached to the holder moves away from the switch, and is not limited to a direction perpendicular to the "first direction" according to the present invention. Therefore, for example, the "second direction" according to the present invention may be a direction perpendicular to the two directions, the X direction shown in FIG. 4 and the Y direction shown in FIG. 5 (Z direction), or any direction in three-dimensional space defined by these X, Y, and Z directions.

The "switch" according to the present invention is a detection means capable of detecting that a key has been removed from a holder, but "the key has been removed from the holder" is not limited to a state in which the key has been removed from the holder and physically separated, but may also mean a state in which the key has been pulled out slightly from the holder and part of the key is still contained in the holder but the engagement between the key and the holder has been released. In other words, the "switch" according to the present invention only needs to be capable of detecting a change from a state in which the key is attached to the holder to a state in which the key is not attached to the holder.

The item movement detection device according to the present invention can be widely used as a device for detecting the movement of items (taking out, theft, etc.).
