The fourth wall portion W 4 is a wall portion that abuts when the engagement member 4 moves toward the outside of the case body 2 in a direction perpendicular to the inner surface IS of the peripheral wall 22.

Similarly, the fixing portion 221b provided on the second peripheral wall 22b extending in the vertical direction D2 has a first wall portion W1 and a second wall portion W2 that contact the engaging member 4 in the vertical direction D2. In addition, the fixing portion 221b has a third wall portion W3 and a fourth wall portion W4 that come into contact with the engaging member 4 in the lateral direction D2.

Note that the fixing portion 221 may be provided on the bottom plate 21 of the case body 2 instead of the peripheral wall 22. In this case, the fixing part 221 can be a recessed part that is recessed with respect to the surface 21a of the bottom plate 21 with which the panel A1 abuts, for example. In this embodiment, as shown in FIG. 1 and FIG. 2, the fixing portion 221 is recessed from the inner surface IS of the peripheral wall 22 toward the outer surface OS, and the height direction of the peripheral wall 22 (vertical direction in FIG. 3). Then, it is recessed so that a level | step difference may be formed with respect to the surface 21a of the baseplate 21. FIG. The step between the fixing portion 221 and the surface 21a of the bottom plate 21 constitutes the third wall portion W3 among the first to fourth wall portions W1 to W4 described above.

The fixing part 221 is not limited to the concave part. The fixing portion 221 may be configured by a protruding portion that protrudes from the bottom plate 21 and / or the peripheral wall 22 and the like that can suppress movement of the engaging member 4 relative to the fixing portion 221.

The number of fixing portions 221 provided on the peripheral wall 22 is not particularly limited. In the present embodiment, two fixing portions 221 are provided on the first peripheral wall 22a so as to be separated from each other in the lateral direction D1, and two fixed portions 221 are provided on the second peripheral wall 22b so as to be spaced apart from each other in the vertical direction D2. However, it is sufficient that the fixing portions 221 are provided more than the number of holding members 3 provided in the longitudinal direction of each peripheral wall 22. Therefore, the fixing portion 221 may be provided at only one place on each peripheral wall 22 according to the number of holding members 3 or may be provided at a plurality of places. Moreover, in this embodiment, although the fixing | fixed part 221 is provided only in the 1st surrounding wall 22a and the 2nd surrounding wall 22b, you may be provided in the 3rd surrounding wall 22c and the 4th surrounding wall 22d.

The engaging member 4 is attached to the fixing portion 221 of the case body 2, and the holding member 3 is coupled to the engaging member 4. Thereby, the holding member 3 is fixed to the bottom plate 21 and / or the peripheral wall 22. As shown in FIGS. 1 and 2, the engaging member 4 is connected to the base 41 fixed to the fixing portion 221 provided on the bottom plate 21 and / or the peripheral wall 22 and attached to the case body 2, and the holding member 3 is connected.

The base 41 has a third contact portion 41c and a fourth contact portion 41d that contact the third wall portion W3 and the fourth wall portion W4 of the fixed portion 221, respectively. Since the first to fourth contact portions 41a to 41d of the base portion 41 can contact the first to fourth wall portions W1 to W4 of the fixing portion 221, the engagement member 4 moves relative to the fixing portion 221. Is suppressed, and the movement of the holding member 3 with respect to the case body 2 is restricted.

Note that the base 41 can be fixed to the fixing portion 221, and the shape and structure of the base 41 are not particularly limited as long as the movement of the engagement member 4 with respect to the fixing portion 221 can be suppressed.

The connected portion 42 is a portion to which the holding member 3 is connected. By connecting a connecting portion 3 a of the holding member 3, which will be described later, to the connected portion 42, the holding member 3 is indirectly connected to the case body 2 via the engaging member 4. The connected portion 42 moves in a direction perpendicular to the longitudinal direction of the peripheral wall 22 and the inner surface IS of the peripheral wall 22 with respect to the engaging member 4 when the connecting portion 3 a of the holding member 3 is connected. To suppress. Thereby, the movement to the horizontal direction D1 and the vertical direction D2 with respect to the engaging member 4 of the holding member 3 is suppressed.

The shape and structure of the connected portion 42 are not particularly limited as long as the connecting portion 3a of the holding member 3 can be connected so that the holding member 3 does not move in the horizontal direction D1 and the vertical direction D2 with respect to the engaging member 4. In the present embodiment, the coupled portion 42 includes a protruding portion that protrudes from the base portion 41 in a direction perpendicular to the surface 21 a of the bottom plate 21. In FIG. 1, the connected portion 42 is constituted by two rod-like bodies protruding from the base portion 41. The connected portion 42 may be, for example, a plate-like body or a recessed portion, depending on the shape and structure of the connecting portion 3 a of the holding member 3.

In the packing case 1, the engaging member 4 has an arbitrary configuration, and a connected portion capable of connecting the connecting portion 3 a of the holding member 3 is integrally provided on the bottom plate 21 and / or the peripheral wall 22, so that the holding member 3 is provided. You may attach to the baseplate 21 and / or the surrounding wall 22 directly. The to-be-connected part in this case can be set as the structure similar to the to-be-connected part 42 of the engaging member 4 mentioned above.

The holding member 3 suppresses the movement of the panel module A inside the case body 2 by being attached to the panel A1 of the panel module A in contact with the upper side. As shown in FIG. 4, the holding member 3 is directly or indirectly connected to the contact portion 3 b having a contact surface Su 1 (see FIG. 6) that contacts the panel A 1 from above, and the bottom plate 21 and / or the peripheral wall 22. It has the connection part 3a connected with. The holding member 3 has a non-contact portion 3c that extends continuously from the contact portion 3b and does not contact the panel A1, and the connecting portion 3a is formed in the non-contact portion 3c. As shown in FIG. 3, the contact portion 3 b refers to a predetermined region set as a portion of the holding member 3 that overlaps the first surface A 11 of the panel A 1. 1 is attached to the surface A11. The non-contact part 3c has the connection part 3a among the holding members 3, and says the predetermined area | region set as a location which does not overlap with 1st surface A11 of panel A1. As shown in FIG. 6, the contact portion 3b has an adhesive portion 31 on the contact surface Su1.

In the present embodiment, the holding member 3 is attached to the first surface (upper surface) A11 of the panel A1 by the adhesive portion 31. As shown in FIG. 3, the holding member 3 is attached to each of the plurality of panels A 1 arranged in a stacked manner. In FIG. 3, spacers may be provided between the non-contact portions 3 c of the plurality of holding members 3 that are separated in the height direction of the peripheral wall 22.

Further, as shown in FIG. 5, the holding member 3 may be attached only to a single panel A1 among the plurality of panels A1 arranged in a stacked manner. In this case, for example, the spacer S provided between the plurality of panels A1 can be used as the above-described adhesive sheet to suppress movement in the horizontal direction D1 and the vertical direction D2 with respect to each other between the plurality of panels A1. In this case, there is no need to attach the holding member 3 to all of the plurality of panels A1, which is economical.

In this embodiment, the holding member 3 has a sheet shape. Therefore, there is no need to provide an extra space in the thickness direction of the panel A1 when the holding member 3 is attached to the panel A1, and the panel module A is stacked inside the case body 2 as shown in FIG. The holding member 3 does not become an obstacle when arranging.

In this embodiment, as shown in FIG. 6, the holding member 3 has a base material 32, and the adhesive portion 31 is laminated on the base material 32. The bonding portion 31 is configured by an adhesive applied on the base material 32. The holding member 3 may have a release paper (not shown) that covers the adhesive portion 31 in a state before the holding member 3 is attached to the panel A1.

The base material 32 is a sheet material that functions as a support for the bonding portion 31. The material of the base material 32 is not particularly limited as long as it has a predetermined rigidity and can be easily attached to the panel A1, and various resin materials such as polyethylene terephthalate, polycarbonate, polyimide, and polypropylene subjected to antistatic treatment, for example. Can be used.

The adhesive used for the adhesive part 31 is not particularly limited as long as the adhesive state between the holding member 3 and the panel A1 is maintained when a load is applied to the panel A1. As the adhesive, for example, an acrylic adhesive can be used. The adhesive strength of the adhesive is not particularly limited, but the adhesive strength of the adhesive to non-alkali glass is preferably 5 N / 25 mm or more and 20 N / 25 mm or less, and more preferably 10 N / 25 mm or more and 15 N / 25 mm or less. When the adhesive force is 5 N / 25 mm or more, when a load is applied to the panel A1, it is possible to suppress separation between the adhesive portion 31 of the holding member 3 and the panel A1. When the adhesive strength is 10 N / 25 mm or more, the panel A1 is more stably held by the holding member 3. Moreover, it becomes easy to peel the holding member 3 from panel A1 because adhesive force is 20 N / 25mm or less. When the adhesive force is 15 N / 25 mm or less, the holding member 3 is more easily peeled from the panel A1, and the handleability of the holding member 3 is improved.

The thickness of the sheet-shaped holding member 3 is not particularly limited, but the thickness of the holding member 3 in the contact portion 3b is, for example, equal to or less than the thickness of the spacer S disposed between the pair of stacked panel modules A. Is preferred. In this case, even if the holding member 3 is affixed to the first surface A11 of each panel A1, as shown in FIG. 3, it is formed between the plurality of panels A1 stacked and arranged via the spacers S. In the gap, the holding member 3 can be attached to the first surface A11 of the panel A1. Therefore, by sticking the holding member 3, the number of panels A1 accommodated in the case main body 2 is not reduced and the number of panels A1 accommodated is not affected. Although the thickness (in this embodiment, the thickness of the base material 32) in the contact part 3b of the holding member 3 is not specifically limited, For example, it is preferable that it is 0.05 mm or more and 1.0 mm or less, and is 0.1 mm or more and 0.00. More preferably, it is 3 mm or less. When the thickness of the holding member 3 is not less than 0.05 mm and not more than 1.0 mm, the handleability of attaching the holding member 3 to the panel A1 is improved without affecting the number of accommodated panels A1. Moreover, when the thickness of the holding member 3 is 0.1 mm or more and 0.3 mm or less, the handleability when the holding member 3 is attached to the panel A1 is further improved. In the holding member 3, the thickness of the contact portion 3b may be different from the thickness of the non-contact portion 3c. For example, the thickness of the contact portion 3b may be made thinner than the thickness of the non-contact portion 3c.

The holding member 3 only needs to have a strength that does not damage the holding member 3 itself, the case body 2, and the panel A1 when a load is applied to the panel A1. The holding member 3 preferably has a tensile strength of, for example, 50 MPa or more. When the tensile strength of the holding member 3 is 50 MPa or more, when a load is applied to the panel A1, the holding member 3 is not damaged and the movement of the panel A1 is stably suppressed, and the panel A1 is brought into a predetermined position. Can be held.

As shown in FIG. 4, the shape of the holding member 3 when the sheet-like holding member 3 is viewed from the direction perpendicular to the contact surface Su1 is substantially rectangular in this embodiment. However, the shape of the holding member 3 is not particularly limited. In addition, the size of the holding member 3 is not particularly limited as long as the holding member 3 has a predetermined pasting area that can suppress the movement of the panel A1 when pasted on the panel A1. The size of the holding member 3 is appropriately changed according to the size and weight of the panel A1. The length of the holding member 3 in the direction along the peripheral wall 22 is, for example, 5 to 20% of the length of the edge of the panel A1 to which the holding member 3 is attached, and the length of the inner surface IS of the peripheral wall 22 of the holding member 3 The length in the direction perpendicular to the edge is preferably 10 to 40% of the length of the edge perpendicular to the edge to which the holding member 3 is attached. By setting the size of the holding member 3 to the size described above, the holding member 3 can be easily attached to the panel A1, and the movement of the panel can be stably suppressed.

The connecting portion 3a connects the holding member 3 to the case body 2 by being directly or indirectly connected to the bottom plate 21 and / or the peripheral wall 22. In the present embodiment, the connecting member 3 a of the holding member 3 is connected to the connected portion 42 of the engaging member 4, so that the holding member 3 is disposed at a predetermined position with respect to the case body 2. When the load is applied to the panel A1 to which the holding member 3 is attached and the holding member 3 tries to move together with the panel A1, the connecting portion 3a is connected to the case body 2 (engagement member 4). It connects with the to-be-connected part 42 so that it may not move to the horizontal direction D1 and the vertical direction D2. Since the holding member 3 suppresses the movement of the panel A1 inside the case main body 2, breakage of the circuit board A2 of the panel module A, the end face of the panel A1, and the corners is suppressed. Details of this point will be described later.

If the connecting member 3a can be connected to the connected part 42 so that the holding member 3 does not move in the horizontal direction D1 and the vertical direction D2 with respect to the case main body 2 (engagement member 4), the shape and structure of the connecting part 3a are particularly good. It is not limited. In this embodiment, as shown in FIG. 4, the connecting portion 3 a has a through hole H into which the rod-like connected portion 42 is inserted, a load is applied to the panel A 1, and the holding member 3 is moved from the panel A 1. When a force to be applied is applied, the peripheral edge of the through hole H comes into contact with the outer periphery of the rod-like connected portion 42. Thereby, even if the holding member 3 tries to move in the horizontal direction in the case body 2 together with the panel A1, the peripheral edge of the through hole H is engaged with the connected portion 42, and the movement of the panel A1 and the holding member 3 is suppressed. . In addition, the connection part 3a should just be able to regulate the movement of the holding member 3 with respect to the case main body 2 at least in the horizontal direction D1 and the vertical direction D2 within a predetermined range. When the connecting part 3 a is connected to the connected part 42, a predetermined clearance may be provided between the connecting part 3 a and the connected part 42.

The connecting portion 3a has a circular through hole H in this embodiment. The connection part 3a should just have the engaging part according to the shape of the to-be-connected part 42. FIG. For example, the connecting portion 3a may have a different shape and structure from the illustrated connecting portion 3a, such as a rectangular through-hole that can be engaged with the connected portion 42 of the engaging member 4 and an engaging protrusion. Good.

The holding member 3 may have a reinforcing member 33 in the non-contact portion 3c. The reinforcing member 33 applies a load to the panel A 1 and increases the strength at the place where the connecting portion 3 a and the connected portion 42 are engaged. Thereby, it is suppressed that the connection part 3a is damaged by the load added to panel A1. For example, as shown in FIG. 6, the reinforcing member 33 can be a sheet material laminated on the base material 32. By having the reinforcing member 33, the thickness of the holding member 3 is increased in the connecting portion 3a, and the strength in the connecting portion 3a is increased. Therefore, when a strong force is applied between the connecting portion 3a of the holding member 3 and the connected member 42 due to the load applied to the panel A1, the connecting portion 3a is damaged and the panel A1 moves. Can be suppressed. The material of the reinforcing member 33 is not particularly limited, and the same material as the base material 32 may be laminated, or may be formed of a material having higher rigidity than the base material 32. As the reinforcing member 33, for example, a metal thin plate (iron, stainless steel, aluminum material) can be used in addition to the resin material exemplified for the base material 32.

In the present embodiment, the reinforcing member 33 is provided on the contact surface Su1 of the sheet-shaped holding member 3 as shown in FIG. 6, but the surface on which the reinforcing member 33 is provided is limited to the contact surface Su1 of the holding member 3. Instead, it may be provided on the surface Su2 opposite to the contact surface Su1, or may be provided on both surfaces of the holding member 3.

Further, in the case where the reinforcing member 33 is provided in addition to the base material 32, it is possible to increase the resistance to the compressive force applied to the non-contact portion 3c of the holding member 3. For example, when a load in a direction (left direction in FIG. 6) toward the connected portion 42 to which the connecting portion 3a of the holding member 3 is connected is applied to the panel A1, the rigidity is improved by the reinforcing member 33, so that the panel It can suppress that end surface AE of A1 contact | abuts to the surrounding wall 22. FIG. Further, for example, as shown in FIG. 7, a sheet-shaped reinforcing member 33 is provided on the surface Su2 opposite to the contact surface Su1 of the holding member 3 so as to extend from the non-contact portion 3c to the contact portion 3a. It may be done. In FIG. 7, the reinforcing member 33a covers the non-contact part 3c and covers a part of the contact part 3a beyond the boundary between the non-contact part 3c and the contact part 3a. In this case, it is possible to further increase the resistance force due to the compressive force that the holding member 3 receives due to the load applied to the panel A1. In FIG. 7, in addition to the reinforcing member (first reinforcing member) 33a provided on the surface Su2 of the holding member 3, the contact surface Su1 of the holding member 3 has a reinforcing member (second reinforcing member) 33b. ing. When the reinforcing member 33a is provided, the thickness of the portion of the holding member 3 that overlaps the panel A1 (the thickness of the reinforcing member 33a and the base material 32) is preferably equal to or less than the thickness of the spacer S.

In addition, in order to oppose the compressive force applied to the non-contact part 3c of the holding member 3, it is in contact with the end surface AE of the panel A1 interposed between the end surface AE of the panel A1 and the peripheral wall 22 separately from the holding member 3. A possible contact piece (not shown) may be provided as an auxiliary. Since the reinforcing member 33 can increase the resistance to the compressive force applied to the non-contact portion 3c of the holding member 3, the contact pressure between the contact piece and the end surface AE of the panel A1 is reduced, and the end surface of the panel A1 Damage to AE is suppressed.

Next, the usage method of the packaging case 1 of this embodiment and the effect | action of the holding member 3 are demonstrated. Note that the following usage is merely an example, and the present invention is not limited to the following description.

First, the panel module A is placed on the case body 2, and the outer periphery of the panel module A (the first edge E1, the second edge E2, and the circuit board A2 of the panel A1) is separated from the first to fourth peripheral walls 22a to 22d. It arrange | positions on the baseplate 21 so that it may. When the panel module A is disposed, the engaging member 4 is attached to the fixing portion 221a of the first peripheral wall 22a and the fixing portion 221b of the second peripheral wall 22b of the case body 2. When the engaging member 4 is attached to the fixing

portions

221a and 221b, the connecting portion 3a of the holding member 3 is connected to the connected portion 42 of the engaging member 4, and the release paper covering the adhesive portion 31 of the holding member 3 is peeled off. The adhesive portion 31 is attached to the first surface A11 of the panel A1 (see FIG. 2).

2, the holding member 3 extends toward the inside of the case body 2 in a direction perpendicular to the longitudinal direction of the peripheral wall 22 to which the holding member 3 is attached. Two holding members 3 are attached to the first peripheral wall 22a so as to be separated from each other in the lateral direction D1 that is the longitudinal direction of the first peripheral wall 22a. Two holding members 3 are affixed to the second peripheral wall 22b so as to be separated from each other in the longitudinal direction D2, which is the longitudinal direction of the second peripheral wall 22b. When the holding member 3 is attached to one panel A1, the spacer S is arranged on the panel A1, the next panel A1 is arranged on the spacer S, and the holding member 3 is similarly attached. In this way, the holding member 3 is attached to the plurality of panels A1, and the case main body 2 is covered with the lid to complete the packing operation.

When the plurality of panels A1 are accommodated inside the case body 2, the packing case 1 is transported by a vehicle such as a truck. A load is applied to the panel A1 accommodated inside the case body 2 by braking, curve traveling, or the like when the packaging case 1 is conveyed by the vehicle. For example, a case where the case body 2 is loaded with the lower side (third peripheral wall 22c) in FIG. 2 being the front of the vehicle and the upper side (first peripheral wall 22a) in FIG. explain.

When the vehicle is suddenly braked, the panel A1 accommodated in the case body 2 is applied with a force to move downward in FIG. When such a force is applied to the panel A1, the holding member 3 fixed to the first peripheral wall 22a is attached to the first surface A11 of the panel A1 by the adhesive portion 31, and therefore, downward in FIG. The panel A1 is restrained from moving downward while receiving a tensile force. Therefore, the circuit board A2 is held at a predetermined position inside the case body 2 without colliding with the third peripheral wall 22c.

Further, when the vehicle travels on a sharp curve, the panel A1 accommodated in the case main body 2 is applied with a force to move to the left side in FIG. When such a force is applied to the panel A1, the holding member 3 fixed to the second peripheral wall 22b is attached to the first surface A11 of the panel A1 by the adhesive portion 31, and therefore leftward in FIG. The panel A1 is restrained from moving to the left while receiving a tensile force. Therefore, the circuit board A2 is held at a predetermined position inside the case body 2 without colliding with the fourth peripheral wall 22d.

As described above, in the present embodiment, the holding member 3 is disposed on the third edge E3 and the fourth edge E2 on which the circuit board A2 is provided. It extends toward the panel A1. Therefore, an effective and simple structure can be obtained by sticking the sheet-shaped holding member 3 capable of withstanding the tensile force to the first surface A11 of the panel A1 for the collision of the circuit board A2 that is easily damaged. Can prevent.

2, for example, between the first edge E1 of the panel A1 and the first peripheral wall 22a and the panel A1 with respect to the force that the panel A1 tries to move upward or the force that the panel A1 tries to move to the right. The end surface AE of the panel A1 may be protected by providing a holding piece between the second edge E2 and the second peripheral wall 22b. Further, as described above, the reinforcing member 33 may be provided on the holding member 3 to increase the resistance force against the compressive force of the holding member 3, and the movement of the panel A 1 may be suppressed by the holding member 3.

Further, as described above, since the holding member 3 having the adhesive portion 31 is brought into contact with the panel A1 from above, it is possible to suppress a large load from being locally applied to the end surface AE of the panel A1. Therefore, the risk of breakage of the panel A1 can be reduced. Further, as shown in FIG. 2, the conventional structure in which the holding piece is interposed between the end surface AE of the panel A1 and all the four peripheral walls 22a to 22d to prevent the movement of the panel A1 is a circuit board A2. It cannot be applied to the panel A1 provided over the entire third edge E3 or fourth edge E4 of A1. On the other hand, in the packaging case 1 of the present embodiment, since the holding member 3 is attached from above the panel A1, even if the circuit board A2 is provided over the entire edge of the panel A1, the panel A1 It becomes possible to suppress movement.

In the packaging case 1 of the present embodiment, as shown in FIG. 8, the first holding member 310 is in the vicinity of the first corner portion C1 of the first peripheral wall 22a where the first peripheral wall 22a and the fourth peripheral wall 22d intersect. The second holding member 320 is located in the vicinity of the second corner C2 located in the diagonal direction of the first corner C1 where the second peripheral wall 22b and the third peripheral wall 22c intersect among the second peripheral walls 22b. Is arranged. In this case, the first holding member 310 and the second holding member 320 are affixed in the vicinity of the corners AC1 and AC2 that are diagonal to the rectangular panel A1. Thereby, in addition to the effect demonstrated in Embodiment 1, rotation of the panel module A centering on the gravity center G of panel A1 can be suppressed effectively, and damage to panel A1 and circuit board A2 is suppressed. be able to.

Specifically, when a load is applied to the panel A1, a force may be applied to the panel A1 to rotate about the center of gravity G. The first holding member 310 is disposed in the vicinity of the first corner portion C1 of the case body 2 and the second holding member 320 is disposed in the vicinity of the second corner portion C2, whereby the first and second holding

members

310, 320 is pasted near the corners AC1 and AC2 of the panel A1 farthest from the center of gravity G of the panel A1. Thereby, rotation around the center of gravity G of the panel A1 can be effectively suppressed. More specifically, as shown in FIG. 8, when a rotational force indicated by an arrow AR1 is applied about the center of gravity G of the panel A1, each of the first holding member 310 and the second holding member 320 counters the tensile force. (See arrow R in FIG. 8), the rotation of the panel A1 is suppressed. The same applies when a rotational force in the opposite direction is applied. In this way, by arranging the first holding member 310 and the second holding member 320, rotation about the center of gravity G of the panel A1 is suppressed.

It should be noted that the vicinity of the first corner C1 can be, for example, a range of ¼ or less of the length of the first peripheral wall 22a to which the holding member 3 is connected from the first corner C1. The vicinity of the second corner C2 can be, for example, a range equal to or less than ¼ of the length of the second peripheral wall 22b to which the holding member 3 is coupled from the second corner C2.

In the present embodiment, a single first holding member 310 is attached to the first peripheral wall 22a, and a single second holding member 320 is provided on the second peripheral wall 22b, but the first peripheral wall 22a and / or Alternatively, another holding member other than those illustrated in the second peripheral wall 22b may be provided.

The first holding member 310 and the third holding member 330 are arranged at positions symmetrical to the center of gravity G of the panel A1, and the second holding member 320 and the fourth holding member 340 are about the center of gravity G of the panel A1. Are arranged in symmetrical positions.

In the present embodiment, when a force for moving the panel A1 downward in FIG. 9 is applied, the first holding member 310 fixed to the first peripheral wall 22a works against the downward pulling force. Suppresses the downward movement of A1. Therefore, the circuit board A2 is held at a predetermined position inside the case body 2 without colliding with the third peripheral wall 22c.

In addition, in FIG. 9, when a force is applied to move the panel A1 upward, the third holding member 330 fixed to the third peripheral wall 22c causes the upper surface of the panel A1 to resist the tensile force in the upward direction. Suppresses movement in the direction. Therefore, the first edge E1 of the panel A1 is held at a predetermined position inside the case body 2 without colliding with the first peripheral wall 22a.

In addition, when a force is applied to move the panel A1 in the left direction in FIG. 9, the second holding member 320 fixed to the second peripheral wall 22b causes the left side of the panel A1 to resist the tensile force in the left direction. Suppresses movement in the direction. Therefore, the circuit board A2 of the panel A1 is held at a predetermined position inside the case body 2 without colliding with the fourth peripheral wall 22d.

In addition, when a force is applied to move the panel A1 in the right direction in FIG. 9, the fourth holding member 340 fixed to the fourth peripheral wall 22d moves the right side of the panel A1 against the rightward pulling force. Suppresses movement in the direction. Therefore, the second edge E2 of the panel A1 is held at a predetermined position inside the case body 2 without colliding with the second peripheral wall 22b.

As described above, the first to fourth holding members 310 to 340 extend from the first to fourth peripheral walls 22a to 22d toward the inside of the case body 2, so that the panel A1 can be more stably attached to the case body 2. Can be held inside.

Further, by using the sheet-shaped holding member 3, the holding member 3 can be attached even to the edge having the circuit board A2. In this case, for example, by using the holding member 3 that has been subjected to antistatic treatment as the holding member 3, adverse effects due to static electricity on the circuit board A2 can be prevented.
