Description

  The present invention relates to an impact detection device capable of visually confirming that a packaging box has received an impact.

Generally, when electronic equipment is packed and transported in a packaging box such as a cardboard box, a cushioning material is provided around the packed electronic equipment in order to protect the electronic equipment from impact and vibration. . However, when a large and heavy electronic device such as a multifunction machine or a personal computer is transported in a state packed in the packaging box, if the package falls over during the transportation, it is spread around the electronic device. The shock absorbing material cannot absorb the shock completely. For this reason, the impacted electronic device may break down. In addition, since a failure of the electronic device has occurred inside, the trace of the failure may not appear on the appearance of the electronic device. Therefore, even if the transported electronic device has a failure, there is a problem that the failure of the electronic device is not recognized until it is actually used.
In order to solve such a problem, Patent Document 1 discloses a technique that can visually confirm that an electronic device has received a strong impact. Specifically, Patent Document 1 discloses a technique in which a buffer member is provided with a storage unit filled with a supersaturated solution. When this shock absorbing material receives an impact, the filled solution crystallizes and changes its color tone. Therefore, the customer can visually confirm whether or not the electronic device wrapped in the cushioning material has received a certain level of impact that causes a failure.

JP 2010-85132 A

However, with the conventional cushioning material including the above-mentioned Patent Document 1, it is not possible to confirm that the electronic device has received an impact until the packaging box is opened. Even if the electronic device receives such an impact, the package is received in a state in which the presence or absence of the impact cannot be grasped. For example, a customer who purchases the electronic device recognizes that the customer has received an impact only after opening the delivered packaging box and confirming the color change of the cushioning material. Thereafter, the customer is forced to perform a complicated task of packing the electronic device again and sending it back to the shipping destination. In addition, there is a problem in that customer satisfaction is lowered for companies that have shipped or transported products.
Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide an impact detection device that can visually confirm that an internal electronic device has received an impact without opening the packaging box. It is to provide.

  The impact detection apparatus according to the present invention includes a solution storage unit, a solution absorption unit, and a housing. The solution storage portion is formed so that a colored solution is stored and is torn when subjected to a predetermined pressing force. The solution absorption part is configured to be able to absorb the colored solution. The housing includes a mounting portion that is mounted on the mounted body and an exterior portion that is exposed in a state where the mounting portion is mounted on the mounted body, and is between the mounting portion and the exterior portion. A storage space capable of storing the solution storage portion and the solution absorption portion is formed. The exterior part is formed to be transparent at least at a part facing the solution storage part, and applies the predetermined pressing force to the solution storage part and the first form that does not apply the predetermined pressing force to the solution absorption part. The configuration can be changed between the second configuration and the second configuration. According to the configuration of the impact detection device, when the impact is received, the colored solution in the solution storage portion comes out and is absorbed by the solution absorption portion, so that the color change of the solution absorption portion becomes visible.

  According to the present invention, it is possible to visually confirm that the internal electronic device has received an impact without opening the packaging box.

[First Embodiment]
<Usage example of impact detection device 10>
First, with reference to FIG. 1, the usage example of the impact detection apparatus 10 which concerns on 1st Embodiment of this invention is demonstrated.
As shown in FIG. 1, the impact detection device 10 is used by being mounted on a cardboard box 51 (an example of a mounted body) in which electronic devices such as a multifunction machine, a printer, and a scanner are packaged. The impact detection device 10 receives an impact when the package 52 in which the electronic device is packed in the corrugated cardboard box 51 is impacted by colliding with a floor or a peripheral part such as falling over during transportation. The trace is displayed visually. When the packing body 52 falls, the upper side of the cardboard box 51 receives a larger impact. Therefore, it is desirable that the impact detection device 10 is mounted on the upper corner of the cardboard box 51. In the present embodiment, the impact detection device 10 is mounted on at least two corners on a diagonal line in a plane when the cardboard box 51 is viewed from above. In addition, when a transport worker carries the package 52, the vicinity of the upper corner of the cardboard box 51 is often pressed by hand. Therefore, the impact detection device 10 is located at a position that does not interfere with carrying, specifically, a position that is about the width of the hand below the upper corner, for example, about 10 cm to 15 cm from the upper corner of the cardboard box 51. Mounted in the lower position.

<Configuration of impact detection device 10>
Hereinafter, the configuration of the impact detection device 10 will be described with reference to FIGS. As shown in FIGS. 2 to 4, the impact detection device 10 includes an L-shaped housing 1 (an example of a housing), two ink bags 4 (an example of a solution container), and two water absorbers 5. (An example of a solution absorption part) is provided. The housing 1 includes an L-shaped exterior case 2 (an example of an exterior part) having two surfaces, and an L-shaped attachment-side case 3 (an example of an attachment part) having two surfaces, The outer case 2 and the mounting case 3 are combined. In addition, since the housing 1 is constituted by the outer case 2 and the mounting side case 3, the outer case 2 and the mounting side case 3 can be obtained by individual injection molding. Therefore, it is easier to manufacture the housing 1 than to integrally form the housing 1.

  As shown in FIG. 4, a housing space 40 (an example of a housing space) is formed inside the housing 1. Specifically, the accommodation space 40 is formed between the inner surface 3 </ b> A of the mounting side case 3 and the inner surface 20 </ b> A of the exterior case 2. The ink bag 4 and the water absorbing body 5 are accommodated in the accommodating space 40. In the present embodiment, the outer case 2 is configured to be movable in a direction in which it is in contact with or separated from the mounting side case 3. More specifically, the outer case 2 is in a first posture in which the ink bag 4 in the accommodation space 40 is not compressed without applying a predetermined pressing force (see FIGS. 3A and 4A). And a second posture (see FIGS. 3B and 4B) in which the ink bag 4 is pressed by applying a predetermined pressing force. In such a configuration, for example, when the outer case 2 is in the second posture and the ink bag 4 is compressed, the seal of the compressed ink bag 4 is broken, and the ink 4A contained inside The ink 4A is absorbed by the water absorbing body 5. Hereinafter, the exterior case 2 and the mounting case 3 will be described in detail.

  The mounting side case 3 is obtained by injection molding synthetic resin or the like, and includes a first mounting portion P2 (an example of a first mounting surface portion) and a second mounting portion Q2 (an example of a second mounting surface portion). And have. The first mounting portion P2 and the second mounting portion Q2 are both portions that are mounted on the cardboard box 51. The first mounting portion P2 and the second mounting portion Q2 are connected by a connecting portion 39. Specifically, the first mounting part P2 and the second mounting part Q2 are connected so as to be substantially perpendicular to each other. That is, the first mounting part P2 and the second mounting part Q2 are substantially perpendicular to each other. Thereby, the said mounting | wearing side case 3 of L-shaped type is comprised by planar view. As shown in FIGS. 2A and 4, the first mounting portion P <b> 2 is formed in a rectangular shape in which the side in the horizontal direction 9 is longer than the side in the vertical direction 7 when viewed from the front side. Similarly to the first mounting portion P2, the second mounting portion Q2 is formed in a rectangular shape having a side in the front-rear direction 8 longer than a side in the vertical direction 7 when viewed from the left side. Since the mounting side case 3 is formed in such a shape, the housing 1 can be mounted so as to straddle the two adjacent corners of the rectangular parallelepiped cardboard box 51.

  The housing space 40 is formed between the first mounting portion P2 and the second mounting portion Q2 of the mounting side case 3 and the exterior case 2. The housing space 40 of the housing 1 includes a first compartment 41 corresponding to the first mounting portion P2 of the mounting side case 3, a second compartment 42 corresponding to the second mounting portion Q2, and a connecting space 43. It is divided into. The connecting space 43 is a portion that connects the first compartment 41 and the second compartment 42 to communicate with each other, and the ink bag passes between the first compartment 41 and the second compartment 42 through the connecting space 43. The fluid such as the ink 4A in the fluid 4 can flow. The ink bag 4 and the water absorbent 5 are accommodated in the first compartment 41 and the second compartment 42, respectively. That is, the ink bag 4 and the water absorber 5 are accommodated in the first compartment 41, and the ink bag 4 and the water absorber 5 are individually accommodated in the second compartment 42. Thereby, the said impact detection apparatus 10 can each detect the impact received by the said 2 surface in the state with which it mounted | wore with the 2 surfaces of the said cardboard box 51. FIG.

  A mounting surface 3 </ b> B that is mounted on the cardboard box 51 is formed outside the mounting side case 3. The mounting surface 3B includes a mounting surface 3B1 on the first mounting portion P2 side and a mounting surface 3B2 on the second mounting portion Q2 side. Each of the mounting surfaces 3B1 and 3B2 is flat, and an adhesive material such as a double-sided tape is attached to each of the mounting surfaces 3B1 and 3B2. The surface 3B1 on the first mounting portion P2 side is mounted on one surface of the cardboard box 51, and the surface 3B2 of the second mounting portion Q2 is another surface adjacent to the one surface of the cardboard box 51. Mounted on the surface.

  The inner surface 3 </ b> A of the mounting case 3 includes a first waterproof rod 31, a second waterproof rod 32, a slide rail 33, an internal protrusion 34 (an example of a first protrusion), an inner case guide 35, and case movement prevention. The claw 36 and the like are integrally formed. As shown in FIG. 4, the first waterproof rod 31, the second waterproof rod 32, the slide rail 33, the internal protrusion 34, the inner case guide 35, and the case movement preventing claw 36 are The first compartment 41 and the second compartment 42 are individually provided.

The first waterproof tub 31 and the second waterproof tub 32 prevent the ink 4 </ b> A from leaking from the impact detection device 10.
As shown in FIG. 3, the first waterproof ridge 31 protrudes inward from the inner surface 3 </ b> A and is formed in a ridge shape extending in a direction perpendicular to the paper surface of FIG. 3. The first waterproofing gutters 31 are provided so as to form a pair at respective positions separated by a predetermined interval in the vertical direction 7. Since the first waterproof tub 31 is provided, the ink 4A is prevented from leaking from the vertical direction 7 of the impact detection device 10 when the ink bag 4 is torn and the ink 4A is blown from the inside. The
As shown in FIG. 4, the second waterproof ridge 32 protrudes inward from the inner surface 3 </ b> A and is formed in a ridge shape extending in a direction perpendicular to the paper surface of FIG. 4. The second guide 32 is provided so as to form a pair at respective positions separated by a predetermined interval. Since the second waterproof basin 32 is provided, as in the case of the first waterproof basin 31, when the ink bag 4 is torn and the ink 4A is blown out from the inside, the ink 4A is detected by the impact detection device 10. Leakage from the front-rear direction 8 and the left-right direction 9 is prevented.

  A horizontal through-hole 37 is formed in the second waterproof tub 32 on the connection space 43 side. The through hole 37 is a passage through which the ink 4 </ b> A passes toward the connection space 43 when the ink 4 </ b> A flows out from the ink bag 4 in the accommodation space 40. For example, when the ink bag 4 is torn and the ink 4A flows out in the first compartment 41 of the first exterior part P1, a part of the ink 4A passes through the through-hole 37 in the first compartment 41. And flows into the connection space 43. Further, a part of the ink 4A flows from the connection space 43 into the other second exterior part Q1, reaches the water absorber 5 through the through hole 37 in the second compartment 42, and is absorbed. The

  The internal protrusion 34 is a conical protrusion provided on the inner surface 3A1 and the inner surface 3A2 of the mounting side case 3 corresponding to the mounting surface 3B1 and the mounting surface 3B2. The internal protrusion 34 presses the ink bag 4 when the impact detection device 10 receives an impact and the exterior case 2 changes to a second form to be described later. At this time, the internal protrusion 34 presses one point of the ink bag 4 intensively. In the present embodiment, when the ink bag 4 is pressed by the internal protrusion 34, the ink bag 4 is pressed and the ink bag 4 (see FIG. 5) is broken. The ink bag 4 will be described later.

  The slide rail 33 is a rail-shaped groove that guides a slide guide 23 (described later) included in the exterior case 2 in one direction. As shown in FIG. 4, the slide rail 33 </ b> A on the first mounting portion P <b> 2 side is provided at the right end portion of the inner surface 3 </ b> A of the first mounting portion P <b> 2 and extends in the left-right direction 9. The slide rail 33B on the second mounting portion Q2 side is provided at the rear end portion of the inner surface 3A of the second mounting portion Q2, and extends in the front-rear direction 8. In a state where the slide guide 23 is inserted into the slide rail 33, the exterior case 2 can move in a predetermined direction along the slide rail 33 with respect to the mounting side case 3.

  The inner case guide 35 is formed in a bowl shape bent inward from the peripheral edge of the inner surface 3A. The inner case guide 35 movably supports the outer case 2 with respect to the mounting side case 3 by engaging with an outer case guide 25 (described later) included in the outer case 2. As a result, as shown in FIG. 4, the outer case 2 can be slid in a direction in which the outer case 2 is in contact with or separated from the mounting side case 3. Further, the front end portion of the inner case guide 35 is formed in a bowl shape bent outward. When the distal end portion of the inner case guide 35 is caught by the distal end portion of an outer case guide 25 (described later) included in the exterior case 2, movement of the exterior case 2 in a direction away from the mounting side case 3 is restricted. . This prevents the outer case 2 from being detached from the mounting side case 3.

The case movement preventing claw 36 is formed in a protruding shape near the connecting space 43 of the inner surface 3A. The case movement preventing claw 36 restricts the movement of each other together with the case movement preventing claw 26 of the exterior case 2 described later. The case movement preventing claw 36 and the case movement preventing claw 26 restrict the movement of each other, thereby preventing the position of the exterior case 2 from moving and approaching the mounting side case 3.
When a force weaker than a predetermined impact force is applied to the impact detection device 10, the inclined surface of the case movement preventing claw 26 of the outer case 2 is inclined with respect to the case movement preventing claw 36 of the mounting side case 3. Abutting on the surface, the inclined surfaces are brought together, and contact friction occurs between the inclined surface and the inclined surface. Due to the resistance force due to this contact friction, the outer case 2 cannot move further with respect to the mounting side case 3. Thereby, the exterior case 2 maintains the first form in which a predetermined pressing force is not applied to the ink bag 4. Here, the first form is a form of the outer case 2 when no pressing force is applied to the ink bag 4 as will be described later (the form shown in FIGS. 3A and 4A). ). For example, the cardboard box 51 is pressed from other cardboard boxes 51 by vibration during transportation. When receiving only such a weak force, the impact detection device 10 needs to maintain a state in which no impact is detected. Therefore, the case movement preventing claw 36 and the case movement preventing claw 26 maintain the outer case 2 in the first form by its resistance force.
On the other hand, when a force stronger than a predetermined impact force is applied to the impact detection device 10 due to a fall, the inclined surface of the case movement preventing claw 26 comes into contact with the inclined surface of the case movement preventing claw 36, and After the contact surfaces are combined, they move while sliding on the inclined surfaces against the resistance force due to the contact friction. As a result, the case movement preventing claw 26 on the side close to the connection space 43 gets over the case movement preventing claw 36, and the exterior case 2 applies a predetermined pressing force to the ink bag 4 by the internal protrusion 34. The form changes to the second form to be applied (the form shown in FIGS. 3B and 4B). The ink bag 4 which has received the pressing force by the internal protrusion 34 is broken and blows out the ink 4A therein. The ejected ink 4A is absorbed by the water absorbing body 5. The water absorbent 5 that has absorbed the ink 4A is dyed in the color of the ink 4A.
As described above, the case movement preventing claw 36 and the case movement preventing claw 26 allow the outer case 2 to change between the first form and the second form according to the applied force. It is the mechanism comprised in.
The force applied when the shape is changed between the first form and the second form due to the shape of the case movement preventing claw 36 and the case movement preventing claw 26 and the resistance force due to the contact friction of the inclined surface. The strength is determined. Specifically, when the shape is changed with low strength, the inclination angle of the inclined surfaces is made gentle, the contact friction between the inclined surfaces is reduced, the case movement preventing claw 36 and the case movement preventing claw 26 are made. By reducing the thickness, the force required at the time of form change can be reduced. Further, in the case of changing the form with a strong strength, by making the inclined surfaces steep, increasing the contact friction of the inclined surfaces, or increasing the thickness of the case movement preventing claw 36 and the case movement preventing claw 26, The required force can be increased when the shape changes.

As shown in FIG. 4, the slide guide 23, the case movement preventing claw 26, the slide rail 33, and the case movement preventing claw 36 are individually provided in each of the first compartment 41 and the second compartment 42. Is provided. This is because the exterior case includes a case where an impact is received from a later-described first exterior part P1 side included in the exterior case 2 and a case where an impact is received from a later-described second exterior part Q1 side included in the exterior case 2. This is because the part involved in the form change of case 2 is different.
For example, when the exterior case 2 receives the impact from the first exterior part P1 side and the exterior case 2 becomes the second form, the case movement preventing claw 26B of the second exterior part Q1 is the case of the second mounting part Q2. Moving over the movement preventing claw 36B, the slide guide 23B of the second exterior part Q1 moves backward along the slide rail 33B of the second mounting part Q2. As a result, the outer case 2 moves rearward with respect to the mounting side case 3. In this case, since the space of the first compartment 41 is narrowed, the ink bag 4 in the first compartment 41 is pressed by the internal protrusion 34 or an internal protrusion 24A (an example of the first protrusion) described later. Torn. On the other hand, since the space of the second compartment 42 is not narrowed, the ink bag 4 of the second compartment 42 is not broken by the internal protrusion 34 or the internal protrusion 24A.
Similarly, when the exterior case 2 receives the impact from the second exterior part Q1 side and the case 2 is in the second form, the case movement preventing claw 26A of the first exterior part P1 is attached to the first mounting part P2. It moves over the case movement preventing claw 36A, and the slide guide 23A of the first exterior part P1 moves backward along the slide rail 33A of the first mounting part P2. As a result, the outer case 2 moves to the right with respect to the mounting case 3. In this case, since the space of the second compartment 42 is narrowed, the ink bag 4 of the first compartment 41 is pressed and broken by the internal protrusion 34 and the internal protrusion 24A. On the other hand, since the space of the first compartment 41 is not narrowed, the ink bag 4 in the first compartment 41 is not broken by the internal protrusion 34 or the internal protrusion 24A.

  The outer case 2 is obtained by injection molding a synthetic resin or the like, and is, for example, a transparent and flexible plastic case. The outer case 2 is supported by the mounting side case 3 so as to cover the inner surface 3 </ b> A of the mounting side case 3. The exterior case 2 is exposed on the surface in a state where the mounting case 3 is mounted on the cardboard box 51. The outer case 2 is entirely transparent. For this reason, the internal state of the accommodation space 40 can be visually observed through the exterior case 2 from the outside. Of course, it is only necessary that the outer case 2 has at least a part of the outer surface 20B facing the ink bag 4A to be transparent, and more specifically, a part where the state of the water absorbent 5 can be visually observed is formed transparently. It only has to be done.

  As shown in FIG. 2, the exterior case 2 includes a first exterior part P1 corresponding to the first attachment part P2 and a second exterior part Q1 corresponding to the second attachment part Q2. The first exterior part P1 and the second exterior part Q1 are connected by the connection part 39. Specifically, the first exterior part P1 and the second exterior part Q1 are connected so as to be substantially perpendicular to each other. Thereby, the housing 1 having an L shape in plan view is formed together with the mounting case 3. As shown in FIG. 2B, the first exterior part P1 is formed in a rectangular shape having a side in the left-right direction 9 longer than a side in the vertical direction 7 when viewed from the front side. Similarly to the first exterior part P1, the second exterior part Q1 is formed in a rectangular shape in which the side in the front-rear direction 8 is longer than the side in the up-down direction 7 when viewed from the left side.

  A first waterproof rod 21, a second waterproof rod 22, the slide guide 23, the inner protrusion 24A, the outer case guide 25, and the case movement preventing claw 26 are integrally formed on the inner surface 20A of the exterior case 2. Is formed. As shown in FIG. 4, the first waterproof rod 21, the second waterproof rod 22, the slide guide 23, the inner protrusion 24A, the outer case guide 25, and the case movement preventing claw 26 are: The first compartment 41 and the second compartment 42 are individually provided.

The first waterproof tub 21 and the second waterproof tub 22 are ridges that prevent the ink 4 </ b> A from leaking from the impact detection device 10.
As shown in FIG. 3, the first waterproof ridge 21 protrudes inward from the inner surface 20 </ b> A and is formed in a ridge shape extending in a direction perpendicular to the paper surface of FIG. 3. The first waterproofing gutters 21 are provided so as to form a pair at respective positions separated by a predetermined interval in the vertical direction 7. The interval between the first waterproof ridges 21 is formed wider than the interval between the first waterproof ridges 31. When the exterior case 2 is pressed from the outside and pressed against the mounting case 3, the first waterproof ridge 21 of the exterior case 2 and the first waterproof ridge 31 of the mounting case 3 overlap in the horizontal direction. . Therefore, even if the ink 4A blows out from the pressed ink bag 4 vigorously, the first waterproof ridge 21 and the first waterproof ridge 31 impede the force, and the ink 4A Leakage from the vertical direction 7 is prevented.
As shown in FIG. 4, the second waterproof ridge 22 protrudes inward from the inner surface 20 </ b> A and is formed in a ridge shape extending in a direction perpendicular to the paper surface of FIG. 4. The said 2nd waterproofing gutter 22 is provided so that it may make a pair in each position spaced apart by predetermined spacing. The interval between the second waterproof rods 22 is formed wider than the interval between the second waterproof rods 32. When the exterior case 2 is pressed from the outside and pressed against the mounting case 3, the second waterproof ridge 22 of the exterior case 2 and the second waterproof ridge 32 of the mounting case 3 intersect in the horizontal direction. . For this reason, even if the ink 4A blows out from the pressed ink bag 4 vigorously, the second waterproof ridge 22 and the second waterproof ridge 32 prevent the momentum. Further, the ink 4A that has flowed out of the ink bag 4 is moved to the outside by the second waterproof tub 22 and the second waterproof tub 32 on the end side of the impact detection device 10 in which a through hole 27 described later is not formed. It does not flow out, but flows out only from a later-described through hole 27 to the connection space 43 side.

  Similar to the second waterproof rod 32, the horizontal through hole 27 is formed in the second waterproof rod 22 on the connection space 43 side. When the second waterproof rod 22 and the second waterproof rod 32 overlap with each other due to an impact, the through hole 27 of the second waterproof rod 22 and the through hole 37 of the second waterproof rod 32 overlap. Is formed. As a result, the ink 4A can flow in the connection space 43 between the first compartment 41 corresponding to the first mounting portion P2 and the second compartment 42 corresponding to the second mounting portion Q2. .

  The internal protrusion 24A is a conical protrusion provided on the inner surface 20A of the exterior case 2 corresponding to the outer surface 20B of the first exterior portion P1 and the outer surface 20B of the second exterior portion Q1. The internal protrusion 24A presses the ink bag 4 when the impact detection device 10 receives an impact and the exterior case 2 changes to a second form described later. At this time, the internal protrusion 24A presses one point of the ink bag 4 intensively. In the present embodiment, when the ink bag 4 is pressed by the internal protrusion 24A and the internal protrusion 34, the ink bag 4 is pressed and the ink bag 4 (see FIG. 5) is broken.

  The outer case guide 25 is formed in a bowl shape bent inward from the peripheral edge of the inner surface 20A. The outer case guide 25 movably supports the outer case 2 relative to the mounting side case 3 by engaging with the inner case guide 35. Specifically, the outer case guide 25 is externally fitted to the inner case guide 35, and the outer case 2 is brought into contact with and separated from the mounting side case 3 with the outer side surface serving as a guide surface. Supports sliding movement. In the present embodiment, the outer case 2 is shown in a first posture (FIGS. 3A and 4A) in which a predetermined pressing force is not applied to the ink bag 4 accommodated in the accommodation space 40. Position) and a second posture (position shown in FIGS. 3B and 4B) that applies a force equal to or greater than a predetermined pressing force to the ink bag 4 accommodated in the accommodation space 40. Supported to be movable between. Here, the predetermined pressing force is a force to the extent that the ink bag 4 is squeezed and the ink bag 4 is broken by the internal protrusion 34, as will be described later. The form of the exterior case 2 when in the first position corresponds to the first form of the present invention, and the form of the exterior case 2 when in the second position corresponds to the second form of the present invention. To do.

  The distal end portion of the outer case guide 25 is formed in a bowl shape bent inward. The outer case guide 25 is prevented from being detached from the mounting side case 3 by the front end portion of the outer case guide 25 being caught by the front end portion of the inner case guide 35.

  The case movement preventing claw 26 is formed in a protruding shape near the connecting space 43 of the inner surface 20A. The case movement preventing claw 26 is disposed at a position closer to the connection space 43 than the case movement preventing claw 36 when the outer case 2 is in the first form when in the first posture. As described above, the case movement preventing claw 36 together with the case movement preventing claw 26 prevents the outer case 2 from moving. The strength of the impact force that changes the form of the exterior case 2 from the first form to the second form is the shape, size, position, and number of the case movement prevention claw 36 and the case movement prevention claw 26. Can be determined in advance.

  Further, an external protrusion 24 (an example of a second protrusion) is integrally formed on the outer surface 20B of the outer case 2. The external protrusion 24 is provided on each of the outer surface 20B1 of the first exterior part P1 and the outer surface 20B2 of the second exterior part Q1. Specifically, the external protrusion 24 is provided on the outer surface 20B of the exterior case 2 on the opposite side of the mounting side case 3 from the first mounting portion P2 and the second mounting portion Q2. The external protrusion 24 protrudes outward from the outer surface 20B, and has a blunt end and a wide skirt. The outer protrusion 24 is provided on the outer surface 20B at a position on the back side of the inner protrusion 24A formed on the inner surface 20A of the outer case 2. In a state where the impact detection device 10 is mounted on the cardboard box 51, the external protrusion 24 protrudes outward from the outer surface 20B. Therefore, when the impact detection device 10 receives an impact from the outer surface 20B side, the external protrusion 24 receives an impact force at one point.

The ink bag 4 is a soft plastic bag that contains the water-soluble ink 4A and is torn when subjected to a predetermined pressing force, and is formed in a flat shape. More specifically, the ink 4A contained in the ink bag 4 provided in the first compartment 41 has a predetermined first color. The ink 4A accommodated in the ink bag 4 provided in the second compartment 42 is a second color different from the first color.
Therefore, if the direction of the electronic device packed in the cardboard box 51 is made to correspond to the color of the ink 4A, it can be determined which surface of the electronic device is impacted without opening the packing body 52. can do.
For example, the first compartment 41 having the ink bag 4 containing the red ink 4 </ b> A is made to correspond to the direction in which a shock-sensitive surface such as an operation display unit or an uneven surface of an electronic device is packed. . The second compartment 42 having the ink bag 4 containing the blue ink 4A is made to correspond to the direction in which a strong surface such as a sturdy part or a smooth surface of the electronic device is packed. Thereby, even if it does not open the said package 52, the direction of the electronic device which received the impact can be judged. Thereby, the repair worker can predict whether or not the internal electronic device needs to be repaired.

  The water absorbent 5 is made of an absorbent material capable of absorbing the ink 4A, and is formed in a flat shape as shown in FIG. The area of the flat portion of the water absorbing body 5 is substantially the same as or wider than the area of the flat portion of the ink bag 4. Specifically, the water absorbent 5 is a water absorbent polymer, a water absorbent paper, a water absorbent resin, a water absorbent fiber, or the like. The water absorbing body 5 is white in a state where it does not absorb the ink 4A, and is colored in the same color as the ink 4A by absorbing the ink 4A coming out of the ink bag 4. The water absorbing body 5 is not limited to the above-described one, and any material and color may be used as long as the water absorbing body 5 is discolored by coloring with the ink 4A.

  Since the ink bag 4 and the water absorbing body 5 are formed in a flat shape, the ink bag 4 and the water absorbing body 5 can be stored in the storage space 40 of the mounting side case 3 in a stacked state. is there. Therefore, the housing 1 and the impact detection device 10 as a whole can be made thin. The impact detection device 10 can be installed in a narrow area. As a result, even if the cardboard boxes 51 mounted with the impact detection device 10 are arranged side by side, the dead space does not increase.

  The relationship between the amount of the ink 4 </ b> A accommodated in the ink bag 4 and the water absorption amount of the water absorbent 5 is determined by the ink 4 </ b> A discharged from the ink bag 4 in the first compartment 41. It is kept so as to be absorbed by the water absorbing body 5 and a part of the water absorbing body 5 in the second compartment 42. Conversely, the ink 4A discharged from the ink bag 4 in the second compartment 42 is absorbed by the water absorbent 5 in the second compartment 42 and a part of the water absorbent 5 in the first compartment 41. Is kept. The position where the ink 4 </ b> A of one of the ink bags 4 is absorbed by the other water absorbent 5 is a part of a region that can be seen from the outside of the outer case 2. By maintaining the relationship as described above, the water-absorbing body 5 on the impacted surface and the water-absorbing body 5 on the adjacent surface of the impacted surface have different areas stained with the ink 4A. Therefore, if one surface of the impact detection device 10 mounted on the cardboard box 51 is confirmed, it can be confirmed whether or not the confirmed one surface and another surface adjacent thereto have received an impact. Thereby, it is possible to confirm that the packaging body 52 has received an impact without checking all the surfaces of the impact detection device 10 mounted on the cardboard box 51.

Next, with reference to FIGS. 3B and 4B, a mechanism in which the impact detection device 10 detects an impact by an impact will be described. FIG. 3B is a diagram showing a change when the impact detection device 10 receives an impact in the cross-sectional structure taken along the line AA in FIG. FIG. 4B is a diagram showing a change when the impact detection device 10 receives an impact in the cross-sectional structure taken along the line BB in FIG. 2B.
The housing 1 is configured by combining the exterior case 2 and the mounting side case 3 which are separate components. The housing 1 has a configuration in which the exterior case 2 moves upon receiving an impact and a configuration in which the exterior case 2 is recessed. Thereby, the impact detection apparatus 10 is formed so that the ink bag 4 accommodated therein is pressed when receiving an impact.

A configuration in which the outer case 2 of the housing 1 moves will be described.
The housing 1 mounted on the cardboard box 51 maintains the first form and supports the mounting case 3 and the outer case 2 at a distance that does not apply a pressing force to the ink bag 4.
When the external protrusion 24 of the first exterior part P1 of the exterior case 2 receives an impact, the case movement prevention claw 26B of the second exterior part Q1 is replaced with the case movement prevention claw 36B of the second mounting part Q2. Go over and move. At that time, the upper and lower and right outer case guides 25 of the first exterior part P1 are guided in the moving direction by the upper and lower inner case guides 35 of the first mounting part P2. Further, the movement direction of the slide guide 23B of the second exterior part Q1 is guided by the slide rail 33B of the second mounting part Q2. Therefore, as shown in FIGS. 3B and 4B, the outer case 2 moves backward. The moving distance is a distance until the inner surface 20A1 of the first exterior part P1 hits the inner case guide 35 on the upper and lower sides and the right side of the first mounting part P2. As described above, when the outer case 2 receives an impact force larger than the resistance force that prevents the case movement between the case movement preventing claw 26B and the case movement preventing claw 36B, the outer case 2 is attached to the rear side in advance. It is configured to move to a predetermined position.

Next, a configuration in which the outer case 2 of the housing 1 is recessed will be described. The outer case 2 is made of plastic having flexibility, and is formed so as to be recessed toward the inside when the outer protrusion 24 receives a predetermined pressing force.
When the outer case 2 moves to the limit, the inner surface 20A1 of the outer case 2 contacts the inner case guide 35 of the first mounting portion P2 and the inner wall 38 of the mounting side case 3 of the connecting portion 39. To do. Therefore, as shown in FIG. 3 (B) and FIG. 4 (B), the first exterior part P1 of the exterior case 2 has a portion in contact with the inner case guide 35 and the inner wall 38 as a fulcrum. The outer protrusion 24 is recessed so that the vicinity thereof buckles.
Therefore, the housing 1 that has received an impact is transformed into the second form, and the housing-side case 3 is separated from the mounting-side case 3 by a distance that applies a pressing force to the ink bag 4 by the internal protrusion 24A and the internal protrusion 34. The exterior case 2 is supported. In the state where the moving mechanism of the housing 1 is not acting, even if the outer protrusion 24 of the outer case 2 is pressed and the outer case 2 is recessed, the inner protrusion 24A and the inner protrusion 34, the distance at which no pressing force is applied to the ink bag 4 is maintained.

  Thus, the housing 1 takes two forms. One is the first form in which the mounting case 3 and the outer case 2 are supported by a distance that does not apply a pressing force to the ink bag 4. The other is the second configuration in which the mounting case 3 and the outer case 2 are supported by a distance that applies a pressing force to the ink bag 4. In other words, the exterior case 2 is configured to be able to contact and separate with respect to the mounting side case 3 between the first posture as the first form and the second posture as the second form.

<Operation / Effect of Impact Detection Device 10>
Next, the effect | action of the said impact detection apparatus 10 is demonstrated, referring FIG. 3 (B), FIG. 4 (B), and FIG. FIG. 5 is a cross-sectional view showing a state change when the impact detection device 10 receives an impact. In the following, for example, an image forming apparatus such as a multifunction machine is accommodated in the cardboard box 51, and the impact detection device 10 is mounted near the upper corner of the cardboard box 51 as shown in FIG. An example will be described.

  When the cardboard box 51 is laid down and falls, the surface on which the impact detection device 10 is mounted collides with the floor surface and receives a strong impact from the floor surface. If the first exterior part P1 receives an impact, the external protrusion 24 of the first exterior part P1 receives the impact at the time of falling in a concentrated manner. Due to the impact force, the exterior case 2 moves rearward from the first posture, and the case movement preventing claw 26B of the second exterior portion Q1 contacts the case movement preventing claw 36B. Further, when the exterior case 2 further moves rearward, the inclined surface of the case movement preventing claw 26B of the second exterior portion Q1 becomes the inclined surface of the case movement preventing claw 36B of the second mounting portion Q2. After the contact and the contact surfaces are brought together, they move while sliding on the inclined surfaces against the resistance force caused by the contact friction. Thereby, the case movement preventing claw 26B gets over the case movement preventing claw 36B, and the outer case 2 moves to the second posture. That is, the exterior case 2 is in the second form. At that time, the slide guide 23B of the second exterior part Q1 slides along the slide rail 33B of the second mounting part Q2, so that the exterior case 2 can smoothly move rearward. Further, the first exterior part P <b> 1 of the exterior case 2 is deformed so as to be recessed from the impact received by the external protrusion 24. Thereby, the space of the first compartment 41 is narrowed in the front-rear direction 8. Specifically, the internal protrusion 24A and the internal protrusion 34 approach each other.

  As described above, the ink bag 4 and the water absorbing body 5 are disposed between the internal protrusion 24A and the internal protrusion 34. Therefore, when the first compartment 41 is narrowed, the ink bag 4 is pressed by the internal protrusion 24A and the internal protrusion 34. The impact force concentrates on the tip of the internal protrusion 24A and the tip of the internal protrusion 34. Therefore, the ink bag 4 pressed from both sides by the internal protrusion 24A and the internal protrusion 34 is broken, and the ink 4A stored inside is blown in the direction of the arrow in the figure. At that time, the first waterproof tub 21 and the first waterproof tub 31 are in a state of being overlapped with a portion where the ink 4A is blown out from the ink bag 4. Similarly, the second waterproof tub 22 and the second waterproof tub 32 overlap each other with respect to the portion where the ink 4A is blown out from the ink bag 4. Therefore, the ink 4 </ b> A blown out from the ink bag 4 does not leak out from the impact detection device 10. Therefore, the ink 4 </ b> A blown from the ink bag 4 is absorbed by the water absorbent 5 in the first compartment 41. The water absorbent 5 that has absorbed the ink 4A changes to a color corresponding to the ink 4A. The predetermined pressing force is slightly smaller than the force that would cause the image forming apparatus inside the cardboard box 51 to break down. The force is greater than the force received in contact with other cardboard.

As described above, in the present embodiment, a part of the ink 4 </ b> A that has come out of the ink bag 4 is formed between the through hole 27 of the second waterproof tub 22 and the second waterproof tub 32 on the connection space 43 side. It exits from the flow path where the through-hole 37 overlaps, and flows into the second compartment 42 through the connection space 43. Part of the ink 4 </ b> A that has flowed into the second compartment 42 is absorbed by the water absorbent 5 in the second compartment 42. Further, a part of the ink 4 </ b> A flows into the water absorbent 5 adjacent to the ink bag 4 in the first compartment 41 and is absorbed. Accordingly, the water absorbing bodies 5 of the first compartment 41 and the second compartment 42 are changed to colors corresponding to the ink 4A, so that the user can make the first exterior portion P1 of the transparent exterior case 2 transparent. And the discoloration state of the water absorbing body 5 can be visually confirmed from any of the second exterior parts Q1.
Further, the first waterproof jar 21 of the first exterior part P1 and the first waterproof jar 31 of the first mounting part Q1 overlap in the horizontal direction. Therefore, even if the ink 4A blows out from the pressed ink bag 4 vigorously, the first waterproof ridge 21 and the first waterproof ridge 31 impede the force, and the ink 4A Leakage from the vertical direction 7 is prevented. Further, the second waterproof jar 22 of the first exterior part P1 and the second waterproof jar 32 of the first mounting part Q1 intersect in the horizontal direction. For this reason, even if the ink 4A blows out from the pressed ink bag 4 vigorously, the second waterproof ridge 22 and the second waterproof ridge 32 prevent the momentum. Further, the ink 4A that has flowed out of the ink bag 4 has the second waterproof ridge 22 on the end side of the first exterior portion P1 and the second waterproof ridge of the first mounting portion Q1 where the through hole 27 is not formed. 32 prevents it from flowing out of them.

The same operation is performed when the second exterior portion Q1 is turned down so that the second exterior portion Q1 side faces downward.
Further, when the connection part 39 falls down so as to be down, the first exterior part P1 and the second exterior part Q1 operate at the same time receiving an impact. Therefore, the ink bags 4 in both the first compartment 41 and the second compartment 42 are broken and the inks 4A of both colors come out. Both the inks 4 </ b> A are absorbed by the water absorbing bodies 5 of the first compartment 41 and the second compartment 42. A part of both the inks 4 </ b> A is absorbed by the water absorbent 5 in the other first compartment 41 and the second compartment 42. Therefore, the water absorbing body 5 in the vicinity of the connecting portion 39 changes to a color in which the ink 4A in both the first compartment 41 and the second compartment 42 is mixed.

  Since the impact detection device 10 is configured as described above, it is possible to visually recognize from outside the cardboard box 51 that an electronic device such as an image forming apparatus has received an impact without opening the cardboard box 51. Can be easily confirmed. Even when only one surface of the corrugated cardboard box 51 is subjected to an impact, the discoloration of the water absorbent body 5 can be visually observed from the first exterior portion P1 corresponding to the surface, and other than the surface adjacent to the surface. The discoloration of the water absorbing body 5 can also be visually observed from the second exterior part Q1 corresponding to the surface. Thus, the user can easily and quickly determine whether or not the internal electronic device has received an impact without comparing the two surfaces of the cardboard box 51.

<Modification of Embodiment>
(Shape of housing 1)
In the description of the embodiment, the impact detection device 10 has been described with respect to the example in which the cross section viewed from the vertical direction 7 is formed in an L shape. However, the present invention is not limited to this example.
For example, the housing 1 of the impact detection device 10 may have a flat plate shape instead of an L shape in plan view. By forming the impact detection device 10 in a thin flat plate shape, it can be mounted on a surface other than the corner of the cardboard box 51. Since the flat plate-shaped impact detection device 10 can be manufactured with a simple shape, the manufacturing cost can be reduced.
Further, the angle formed between the first mounting portion P2 and the second mounting portion Q2 of the mounting side case 3 may be any angle corresponding to the shape of the cardboard box 51 to be mounted. The housing 1 and the outer case 2 may have a cross-sectional shape with an angle corresponding to the mounting side case 3. In other words, the mounting side case 3 is configured such that the angle between the first mounting portion P2 and the first mounting portion P2 connected to the first mounting portion P2 is a predetermined angle of 180 degrees or less. Part Q2. Further, the housing 1 accommodates the ink bag 4 and the water absorbing body 5 in the accommodating space 40 between the first mounting portion P2 and the second mounting portion Q2 and the exterior case 2, respectively. Thereby, the said impact detection apparatus 10 can be mounted | worn at the corner | corner of the said cardboard box 51 of shapes other than a rectangular parallelepiped. For example, by setting the angle to 60 degrees, the shock detection device 10 is mounted on the corner of a triangular prism, or by setting the angle to 120 degrees, the shock detection device 10 is mounted on a corner of a hexagonal column. Can be considered.

(Modification of connecting part 39)
Although the example in which the connecting portion 39 of the impact detection device 10 has a fixed shape has been described, the invention is not limited to this example. For example, the connecting portion 39 of the impact detection device 10 is formed of a flexible material. Alternatively, the connecting portion 39 may have a mechanism that can be rotated by a hinge or the like. In other words, the exterior case 2 and the mounting side case 3 are configured such that the connecting portion 39 between the first mounting portion P2 and the second mounting portion Q2 of the mounting side case 3 can be bent. Conceivable. With this configuration, the impact detection device 10 can be mounted even when the corner of the cardboard box 51 is other than a substantially right angle. Further, the shock detecting device 10 is stored in a state where no dead space is generated by straightening the connecting portion 39 and setting the first mounting portion P2 and the second mounting portion Q2 to a flat posture. be able to.

  Further, the connecting space 43 of the connecting portion 39 has the first compartment 41 and the first through the through hole 27 and the through hole 37 provided in the second waterproof rod 22 and the second waterproof rod 32. Although an example in which the space between the two-divided chamber 42 is formed to be flowable has been described, the present invention is not limited to this example. For example, it is conceivable that a plurality of thin tubes and grooves connecting the first compartment 41 and the second compartment 42 are formed in the connecting portion 39. Due to a capillary phenomenon or the like, the ink 4A that has flowed out of the ink bag 4 in one compartment is likely to be absorbed by the water absorber 5 in the other compartment.

(Modification of arrangement of ink bag 4 and water absorbent 5)
In the description of the embodiment, the shock detection device 10 has been described as an example in which the mounting case 3, the ink bag 4, the water absorbent 5, and the exterior case 2 are configured in this order. It is not limited to. For example, a configuration in which the ink bag 4 is arranged near the center in the same layer between the mounting side case 3 and the exterior case 2 and the water absorbing body 5 is arranged near the periphery is conceivable. Thereby, the area of the said water absorption body 5 can be reduced and the quantity of the water absorbing material used for the said water absorption body 5 can be reduced. In addition, the impact detection device 10 having a thinner shape than the stacking of the ink bag 4 and the water absorbent 5 can be realized.

(Modification of external projection 24)
Although an example in which one external protrusion 24 is formed on each of the first exterior part P1 and the second exterior part Q1 of the exterior case 2 has been described, the present invention is not limited to this example. For example, a case in which a plurality of external protrusions 24 are formed on the first exterior part P1 and the second exterior part Q1 of the exterior case 2 can be considered. Thereby, the location where the impact is applied to the outer case 2 can be dispersed. Therefore, it is possible to prevent the impact force exceeding the limit from being concentrated on one place of the outer case 2 and to prevent the outer case 2 from being damaged. Of course, the outer protrusion 24 may not be formed on the first exterior part P1 and the second exterior part Q1 of the exterior case 2. Thereby, the said exterior case 2 can be made into a simple shape, and manufacturing cost can be reduced.
The example in which the one external protrusion 24 is formed in the vicinity of the middle in the vertical direction 7 of the first exterior part P1 and the second exterior part Q1 of the exterior case 2 has been described. However, the present invention is not limited to this example. Absent. For example, it is conceivable that the outer protrusion 24 is formed above the first exterior part P1 and the second exterior part Q1 of the exterior case 2. Thereby, the exterior case 2 becomes easy to receive an impact, and the sensitivity due to the impact can be increased.

(Modified example of internal protrusion 24A and internal protrusion 34)
Although an example in which one internal protrusion 24A and one internal protrusion 34 are formed in each of the first compartment 41 and the second compartment 42 has been described, the present invention is not limited to this example.
For example, a plurality of the internal protrusions 24A and a plurality of the internal protrusions 34 may be formed in each of the first compartment 41 and the second compartment 42. Thereby, the places where the pressing force is applied to the ink bag 4 due to the impact can be dispersed. Therefore, it is possible to weaken the momentum of the ink 4A from the ink bag 4 and prevent the ink 4A from leaking from the impact detection device 10.
For example, each of the first compartment 41 and the second compartment 42 may be formed with only one of the internal protrusion 24A and the internal protrusion 34. Further, it is conceivable that the internal protrusion 24A and the internal protrusion 34 are not formed. Thereby, the shape of the said exterior case 2 and the said mounting | wearing side case 3 can be simplified, and manufacturing cost can be suppressed.
The example in which the one internal protrusion 24A and the one internal protrusion 34 of the first compartment 41 and the second compartment 42 press the vicinity of the center of the ink bag 4 has been described. However, the present invention is not limited to this example. is not.
For example, it is conceivable that the internal projection 24A and the internal projection 34 of the first compartment 41 and the second compartment 42 are formed at positions close to the connecting portion 39 side. Accordingly, the ink 4A that has come out of the ink bag 4 in one of the first compartment 41 and the second compartment 42 can easily flow into the other first compartment 41 and the second compartment 42. Therefore, the ink 4 </ b> A that has come out of one of the ink bags 4 is easily absorbed by the other water absorbent 5.

(Modification of transparent exterior case 2)
Although an example in which the outer case 2 is entirely transparent has been described, the present invention is not limited to this example. For example, the exterior case 2 in which transparent portions are linearly formed in the front-rear direction 8 and the left-right direction 9 and the other portions are formed entirely black can be considered. Thereby, the color of the water absorbing body 5 that has absorbed the ink 4A is conspicuous. Therefore, it becomes easy to confirm the presence or absence of a collision. Further, according to this, the amount of the ink 4A accommodated in the ink bag 4 corresponding to the invisible portion and the amount of the water absorbing body 5 can be reduced.
Further, a configuration in which the transparent portion of the outer case 2 is formed in a letter shape such as “with impact” is conceivable. Due to the water absorbing body 5 that has absorbed the ink 4A, the character “with impact” of the outer case 2 becomes clear. Therefore, a recipient of the packing body 52 who has no knowledge about the impact detection device 10 can recognize that the impact detection device 10 has been operated and received an impact.

(Modification of the mounting portion of the mounting side case 3)
The example in which the double-faced tape for mounting on the cardboard box 51 is attached to the mounting surface 3B1 of the first mounting part P2 and the mounting surface 3B2 of the second mounting part Q2 has been described. It is not limited to. For example, the mounting surface 3B1 and the mounting surface 3B2 may be directly added with an adhesive.
In addition, although the example in which the first mounting part P2 and the second mounting part Q2 are formed in a flat shape has been described, the present invention is not limited to this example. For example, the first mounting portion P2 and the second mounting portion Q2 are formed with foldable protrusions, and after the protrusions are pierced into the mounting portion of the cardboard box 51, inside the cardboard box 51 The protrusion may be attached by bending.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described. Here, the difference from the first embodiment is the configuration of the housing 1, and the other parts are the same as those of the first embodiment. Therefore, only the different parts will be described here, and the common parts will be described. Description is omitted.
In the description of the first embodiment, the mounting side case 3 and the outer case 2 of the housing 1 have been described as separate components, but the present invention is not limited to this example. For example, the housing 1 may be an integrally molded plastic.

With reference to FIG. 6 (A), the configuration of the impact detection device 11 will be described. FIG. 6A is a cross-sectional view schematically showing a cross-sectional structure of the impact detection device 11 from the first exterior part P1 to the first mounting part P2.
The housing 1A is an integrally molded plastic casing with a transparent surface, and the inner protrusion 34 is formed on the inner surface 30A on the first mounting portion P2 side. Further, the side surface portion 6A (front-rear direction 8 in the figure) between the first exterior portion P1 and the first mounting portion P2 of the housing 1A is flexible and is exposed to the outside when receiving a predetermined impact force. Bend. The ink bag 4 and the water absorbing body 5 are disposed on the inner surface 2A of the first exterior part P1 of the housing 1A. As described above, the housing 1A has the first form in which the predetermined pressing force is not applied to the ink bag 4 and the first pressing force to the ink bag 4 due to the flexibility of the side surface portion 6A. It is comprised so that a form change is possible between two forms.
Next, the operation of the impact detection device 11 will be described with reference to FIG. FIG. 6B is a cross-sectional view showing a state change when the impact detection device 11 receives an impact.
When the cardboard box 51 falls, the impact detection device 11 receives an impact force from the first exterior portion P1 side of the housing 1A. In the housing 1A, the side surface portion 6A is curved outward, the first exterior portion P1 side approaches the first mounting portion P2 side, and the space of the first compartment 41 is narrowed. The ink bag 4 disposed on the inner surface 30A of the housing 1A is pressed by the internal protrusion 34 and broken.
In the impact detection device 11 having such a configuration, the housing 1 </ b> A is integrally formed, so that the outer case 2 does not come off from the mounting side case 3. For this reason, it is possible to prevent the ink 4A contained in the ink bag 4 from leaking as much as possible. In addition, it is possible to prevent as much as possible the illegality of replacing the ink bag 4 and the water absorbent 5 of the impact detection device 11.

[Third Embodiment]
Hereinafter, a third embodiment of the present invention will be described. Here, the difference from the first embodiment is the configuration of the housing 1, and the other parts are the same as those of the first embodiment. Therefore, only the different parts will be described here, and the common parts will be described. Description is omitted.
With reference to FIG. 7A, the structure and configuration of the impact detection device 12 will be described. FIG. 7A is a cross-sectional view schematically showing a cross-sectional structure of the impact detection device 12 from the first exterior part P1 to the first mounting part P2.
The housing 1 </ b> B includes the outer case 2, the mounting side case 3, and the side wall portion 6. The side wall portion 6 is made of rubber, and is a connecting member that fills the space between the exterior case 2 and the mounting side case 3 without a gap. Thereby, the housing 1B is integrated. When receiving a predetermined impact force, the side wall portion 6 is contracted, so that the interval between the exterior case 2 and the mounting side case 3 is narrowed. Further, the inner protrusion 34 is formed on the inner surface 30 </ b> B of the mounting case 3. The ink bag 4 and the water absorbing body 5 are disposed on the inner surface 2B of the first exterior part P1 of the housing 1B. As described above, the housing 1B has a first form in which the predetermined pressing force is not applied to the ink bag 4 and a second state in which the predetermined pressing force is applied to the ink bag 4 due to the elasticity of the side wall portion 6. It is configured so that the form can be changed between forms.
Next, the operation of the impact detection device 11 will be described with reference to FIG. FIG. 7B is a cross-sectional view showing a change in state when the impact detection device 11 receives an impact.
When the cardboard box 51 falls, the impact detection device 12 receives impact force from the first exterior portion P1 side of the housing 1B. In the housing 1B, when the side wall portion 6 is contracted, the first exterior portion P1 side approaches the first mounting portion P2 side, and the space of the first compartment 41 is narrowed. The ink bag 4 disposed on the inner surface 2B of the housing 1B is pressed by the internal protrusion 34 and is torn.

[Fourth Embodiment]
Hereinafter, a third embodiment of the present invention will be described. Here, the difference from the first embodiment is the configuration of the housing 1, and the other parts are the same as those of the first embodiment. Therefore, only the different parts will be described here, and the common parts will be described. Description is omitted.
With reference to FIG. 8 (A), the configuration of the impact detection device 13 will be described. FIG. 8A is a cross-sectional view schematically showing a cross-sectional structure of the impact detection device 13 from the first exterior part P1 to the first mounting part P2.
The housing 1C is an integrally molded plastic casing with a transparent surface, and the inner protrusion 34 is formed on the inner surface 30C on the first mounting portion P2 side. Further, the external protrusion 24 is formed on the first exterior part P1 of the housing 1C. The first exterior part P1 is flexible, and is recessed toward the inner surface 2C side of the housing 1C when the external protrusion 24 receives a predetermined impact force. Further, the ink bag 4 and the water absorbing body 5 are arranged on the inner surface 2C of the first exterior part P1 of the housing 1C. Thus, the housing 1C applies the predetermined pressing force to the ink bag 4 and the first form that does not apply the predetermined pressing force to the ink bag 4 due to the flexibility of the first exterior portion P1. The configuration can be changed between the second configuration and the second configuration.
Next, the operation of the impact detection device 13 will be described with reference to FIG. FIG. 8B is a cross-sectional view showing a change in state when the impact detection device 13 receives an impact.
When the cardboard box 51 falls, the impact detector 13 receives an impact force from the first exterior portion P1 side of the housing 1C. In the housing 1C, the first exterior portion P1 side is recessed toward the inner surface 2C side, the first exterior portion P1 side approaches the first mounting portion P2 side, and the space of the first compartment 41 is narrowed. The ink bag 4 disposed on the inner surface 2C of the housing 1C is pressed by the internal protrusion 34 and broken.
The impact detection device 13 having such a configuration can be manufactured at low cost because the configuration of the housing 1C is simple.
