  A reader such as a non-contact communication device contains various electronic components inside, and a structure capable of protecting these components from a drop impact or the like (that is, a structure excellent in impact resistance) is required. . As a technique for protecting a component in the case from an impact with respect to this type of reading apparatus, for example, a technique disclosed in Patent Document 1 has been proposed. In this technology, the connecting part that connects the case and the frame body is configured to be elastically deformable.

  By the way, in recent years, along with the improvement of reading performance and advancement of functions, the internal devices in the reading device tend to be large, and a large acceleration or a large impact is likely to occur due to an unintended drop or the like. When such a large change in acceleration or a large impact occurs, there is a further concern that unintended large deformation will occur in the case, or interference between unintended parts will occur in the case. When such a situation occurs, there is a problem that internal components are easily destroyed and characteristic changes are caused, and in particular, circuit boards on which electronic parts are mounted are prone to the effects of destruction and characteristic changes. Tends to be more serious. Because of such circumstances, this type of reading apparatus is required to take measures that do not affect the circuit board as much as possible even when a sudden acceleration change or a large impact is applied to the case due to dropping or the like.

  The present invention has been made in order to solve the above-described problems, and in a reading apparatus in which a circuit board is accommodated in a case, even when a sudden acceleration change or a large impact is applied to the case, the influence is exerted. An object of the present invention is to provide a circuit board that is difficult to reach.

The invention of claim 1
A circuit board;
A holder for holding the circuit board;
A case in which the circuit board accommodates a combined body held by the holder;
With
The holder is
A substrate holder to which the circuit board is fixed;
A frame portion disposed between the substrate holding portion and the case around the substrate holding portion;
A connecting portion for connecting the substrate holding portion and the frame portion;
An impact mitigating portion capable of mitigating an impact transmitted from the case side to the combined body side;
I have a,
The frame portion is arranged in a configuration surrounding the periphery of the substrate holder in an annular space between the outer peripheral surface of the inner peripheral surface of the frame portion and the substrate holder is characterized that you have configured .

In the invention of claim 1, the combined body in which the circuit board is held by the holder is housed in the case, and the holder includes a board holding part to which the circuit board is fixed, and a periphery of the board holding part. A frame portion disposed between the substrate holding portion and the case, a connection portion connecting the substrate holding portion and the frame portion, and an impact relaxation portion capable of reducing an impact transmitted from the case side to the combined body side. Is provided.
In this way, when the circuit board is held by the board holding part and the frame part is arranged around the board holding part, when vibration or impact occurs, the components outside the frame part are transferred to the circuit board. It becomes difficult to interfere in the vicinity. For example, when the case is deformed due to an impact from the outside of the apparatus, it is easy to protect the deformed part by hitting the frame part before it reaches the substrate holding part side. It can be effectively protected. Furthermore, the holder is provided with an impact mitigation part, and the impact transmitted from the case side to the coupling body side is easily mitigated, so that not only direct interference (contact etc.) of parts outside the frame part but also the coupling body It is also easy to suppress shocks and vibrations propagating through the.
In particular, the frame portion is arranged in a ring shape surrounding the substrate holding portion, and a space is formed between the inner peripheral surface of the frame portion and the outer peripheral surface of the substrate holding portion. In this way, if the frame portion is arranged in an annular shape so as to surround the substrate holding portion, it functions to protect the substrate holding portion over the periphery of the substrate holding portion, so that the substrate holding portion can be protected more uniformly. Can do. Moreover, since a space is formed between the annular frame portion and the substrate holding portion, even if a part of the case collides with the frame portion and the frame portion bends, the space portion is bent. As far as possible, the frame portion hardly interferes with the substrate holding portion. In addition, when a part of the case collides with the frame portion and the frame portion bends, the effect of absorbing the impact force is surely produced while the frame portion is displaced in the space. Even if the frame portion reaches the substrate holding portion and comes into contact with the substrate holding portion, the substrate holding portion is difficult to be pressed with a strong force at the time of contact.

In the invention of claim 9 , the impact relaxation portion includes a spring portion that can be elastically deformed, and the impact transmitted from the case to at least one of the frame portion and the substrate holding portion is relaxed by elastic deformation of the spring portion. ing. According to this structure, the impact and vibration transmitted from the case can be more effectively absorbed by elastic deformation by the spring portion.

In the invention of claim 10 , the outer wall portion of the frame portion opposite to the substrate holding portion side is provided with a protruding portion that protrudes on the opposite side of the substrate holding portion side, and this protruding portion is the inner wall portion of the case. Are arranged opposite to each other. In this way, if the convex portion is provided on the outer wall portion of the frame portion and this convex portion is opposed to the inner wall portion of the case, when the case is deformed by an external impact or the like, the case hits the vicinity of the convex portion. It becomes easy and it becomes easy to suppress interference other than a convex part.

In the invention of claim 2 , the impact relaxation portion is formed in the frame portion and is a support target portion that is a part supported by the case, and a spring portion provided in a form connected to the support target portion in the frame portion. I have. And the connection part is arrange | positioned by the structure which connects the site | part away from the support object part and spring part in a frame part, and a board | substrate holding part.
In this configuration, since at least the frame portion is supported by the case, it is easier to suppress vibration and impact transmitted from the case to the substrate holding portion, compared to a configuration in which only the substrate holding portion is supported by the case. Moreover, since the spring part is provided in a form connected to the support target part, and the connection part is provided in a form connecting the part away from the support target part and the spring part, the impact transmitted from the case to the support target part. And vibrations are easily mitigated before reaching the connection part, and vibrations and shocks to the connection part and the substrate holding part connected to the connection part can be further suppressed.

In the invention of claim 3 , the impact relaxation portion includes a slit formed in a cutout shape in the frame portion, and a flexure deformation portion that is disposed adjacent to the slit space in the frame portion and configured to be elastically deformable. It is equipped with. And the impact transmitted to a frame part from a case is relieve | moderated by the elastic deformation of a bending deformation part.
According to this configuration, it is possible to realize a structure capable of effectively mitigating impacts, vibrations, and the like with a simple configuration of a notch-shaped slit and a bending deformation portion adjacent thereto. In addition, since the notch-shaped slit is formed not in the substrate holding portion but in the frame portion, the rigidity of the substrate holding portion is hardly lowered by this slit, and the rigidity in the vicinity of the circuit board can be easily kept high.
In particular, in the frame portion, there are provided a plurality of corner portions formed by connecting two plate-like portions each extending in different directions, and each corner portion has one plate-like portion constituting each corner portion. A slit is formed in a bent shape in a configuration that continues continuously to the other plate-like portion adjacent to it. And the bending deformation part provided in each corner part comprises the composition where a part of one plate-like part which constitutes each corner part, and a part of the other plate-like part were connected, and it bends. Is arranged in a bent shape at a position adjacent to the space of the slit.
According to this configuration, it is possible to reliably enhance the impact mitigation effect near the corner where an impact is easily applied with a simple configuration. In addition, since the slit is configured to be bent and the bending deformation portion is arranged to be bent, even when a force is applied in the direction in which one plate-shaped portion extends, force is applied in the direction in which the other plate-shaped portion extends. Even when applied, even when a force is applied obliquely with respect to the direction in which both plate-like portions extend, the bending deformation portion is easily elastically deformed. Therefore, it is possible to effectively absorb impacts in various directions, and the direction of impacts that cannot be handled is reduced.

In the invention of claim 4 , the impact relaxation portion includes a pair of slits formed in the frame portion, and the bending deformation portion is disposed between both spaces in the pair of slits. According to this configuration, by a simple configuration in which the bending deformation portion is provided between the pair of slits, it is possible to realize a structure in which bending deformation is more likely to occur and the impact relaxation effect is high.

In the invention of claim 5 , the frame portion is configured in a rectangular frame shape having four corner portions, and when the direction orthogonal to the plate surface of the circuit board is the vertical direction, each corner portion includes Two slits form a pair in a configuration that continues from one plate-shaped portion constituting the corner portion to the other plate-shaped portion adjacent to the corner portion and that extends in a bent shape along a plane direction perpendicular to the vertical direction. Is formed. And the bending deformation part provided in each corner | angular part has comprised the structure with which one plate-shaped part and each other plate-shaped part which comprise each corner | angular part were connected, and a pair Are arranged in a configuration extending in a bent shape along a plane direction orthogonal to the vertical direction at a position between the slits. Further, each of the bending deformation portions provided at each of the four corner portions has a protrusion extending in a direction inclined with respect to the direction of the two plate-shaped portions constituting the respective bending deformation portions and on the inner wall surface side of the case. Each part is formed, and each protrusion is configured to be held by the case.
According to this configuration, in the frame portion configured in the rectangular frame shape, the impact can be effectively alleviated with a simple configuration in any of the four corner portions where the impact is easily applied and the stress is easily concentrated. be able to.
Also, in any corner, the slit is formed in a bent shape, and the bending deformation portion is formed in a bent shape. Therefore, even when a force is applied in the extending direction of one plate-like portion, the other plate-like shape is provided. Even when a force is applied in the direction in which the portions extend, or even when a force is applied obliquely with respect to the direction in which the two plate-like portions extend, the bending deformation portion is easily elastically deformed. That is, in any corner portion, it is possible to effectively absorb impacts in various directions, and the types of impacts that cannot be handled as the entire frame portion are further reduced.
Furthermore, since each bending deformation portion configured in a bent shape is arranged with a protruding portion that is inclined with respect to the direction of the plate-like portion extending toward the inner wall surface side of the case, it can be applied to the case by an external impact or the like. When the deformation occurs, the case is likely to hit the protruding portion, and the deformation of the case is more easily received by the deformation portion. Moreover, since the protruding portion protrudes in an inclined direction with respect to the two plate-like portions, when a force is applied to the direction of any plate-like portion with respect to the vicinity of the distal end portion of the protruding portion due to the deformation of the case However, an action of rotating the protruding portion is likely to occur, and this action makes it easy to apply a force to bend each extending portion of the bending deformation portion configured in a bent shape. In other words, even if a force is applied to the vicinity of the tip of the protrusion from the case in any plate-like direction close to the protrusion, the direction of the impact of the bending deformation portion is likely to be absorbed by the rotation of the protrusion. Since it is easily converted into force, it is possible to absorb the shock more effectively.

In the invention of claim 6 , the connecting portion is provided in a configuration for connecting a portion of the frame portion that is out of the slit formation region and the substrate holding portion. According to this configuration, it is possible to increase the impact mitigating effect with a simple configuration, and to make it difficult for the connection portion and the substrate holding portion to transmit the displacement and vibration of the portion (flexible deformation portion) that greatly contributes to the impact mitigation.

In the invention of claim 7 , the slit is formed as a groove having a predetermined width, and extends along a plane direction parallel to the direction of the plate surface of the circuit board. According to this configuration, at least the slit interval is easily increased or decreased, and deformation and return are likely to occur, and at least force in a direction perpendicular to the plate surface of the circuit board is easily absorbed in the vicinity of the slit. The force in the direction that causes the circuit board to bend is easily suppressed.

In the invention of claim 8 , when the direction perpendicular to the plate surface of the circuit board is the vertical direction, the minimum vertical distance between the upper end portion of the combined body and the inner plate surface of the upper wall portion of the case, and The minimum vertical distance between the lower end portion of the combined body and the inner plate surface of the lower wall portion of the case is larger than the width of the slit. In this configuration, even if the entire combined body is relatively moved upward or about the width of the slit, the combined body is less likely to contact the upper wall portion or the lower wall portion of the case. This makes it easier to prevent contact with the case, and the circuit board and the like are further protected.

In the eleventh aspect of the invention, the impact mitigating portion is formed so as to protrude from the case side in the frame portion and to be a portion to be held by the case and to be connected to the holding target portion in the frame portion. The spring part is provided. The case includes a case main body portion that forms an outer shell of the case, and a holding portion that is connected to the inside of the case main body portion and serves as a portion that holds the combined body. When the orthogonal direction is the vertical direction, the holding part is configured to hold a part of the holding target part sandwiched in the vertical direction.
In this way, when the holding structure is configured such that the portion provided with the protruding structure in the frame portion is sandwiched by a part of the case, the holding target portion swings with respect to the holding portion when the case is deformed or the like. Since it becomes easy to release force by such relative displacement, the impact absorption effect is further enhanced.

The case 3 includes a case main body portion 3c that forms an outer shell of the case 3, and a holding portion 3d that is connected to the inside of the case main body portion 3c and serves as a portion that holds the combined body 2.

  And with respect to the slit 90, the bending deformation part 70, and the convex part 80 formed in the frame part 34 in this way, each connection part 36 has the convex part 80 (support object part) and the bending deformation part 70 (spring part). It arrange | positions by the structure which connects the site | part away from and the board | substrate holding part 32. FIG. Specifically, as shown in FIGS. 8 to 11 and the like, a portion of the frame portion 34 that is out of the formation region of the slit 90 (slits 91a, 91b, 92a, 92b, 93a, 93b, 94a, 94b), and the substrate Each connection part 36 is provided in the structure which connects with the holding | maintenance part 32. FIG.

(Example of effects of this configuration)
In the reading device 1 described above, the combined body 2 in which the circuit board 5 is held by the holder 30 is housed in the case 3. The holder 30 includes a substrate holding portion 32 to which the circuit board 5 is fixed, a frame portion 34 disposed between the substrate holding portion 32 and the case 3 around the substrate holding portion 32, and a substrate. A connecting portion 36 for connecting the holding portion 32 and the frame portion 34 and an impact mitigating portion 38 capable of mitigating an impact transmitted from the case 3 side to the combined body 2 side are provided. As described above, when the circuit board 5 is held by the board holding part 32 and the frame part 34 is arranged around the board holding part 32, the outside of the frame part 34 can be obtained when vibration or impact occurs. Are less likely to interfere with the vicinity of the circuit board 5. For example, when the case 3 is deformed due to an impact from the outside of the apparatus or the like, the deformed portion is easily held against the frame portion 34 before reaching the substrate holding portion 32 side. The circuit board 5 and the like can be effectively protected. Further, the holder 30 is provided with an impact mitigating portion 38, and it is easy to mitigate the impact or vibration transmitted from the case 3 side to the coupling body 2 side. It is easy to suppress not only contact etc.) but also impact and vibration propagating through the coupling body 2.

  Further, in this configuration, the impact reducing portion 38 includes a spring portion (flexible deformable portion 70) that can be elastically deformed, and an impact transmitted from the case 3 to the frame portion 34 is elastically deformed by the spring portion (flexible deformable portion 70). It becomes the structure which eases by. According to this configuration, the impact and vibration transmitted from the case 3 can be more effectively absorbed by the elastic deformation by the spring portion (the bending deformation portion 70), and the influence on the vicinity of the substrate holding portion 32 can be further reduced. it can.

  Moreover, in this structure, as shown in FIGS. 3-5 etc., the frame part 34 is arrange | positioned by the structure which encloses the circumference | surroundings of the board | substrate holding | maintenance part 32, and the inner peripheral surface of the said frame part 34 and board | substrate holding | maintenance A space is formed between the outer peripheral surface of the portion 32. In this way, if the frame portion 34 is arranged in an annular shape so as to surround the substrate holding portion 32, the substrate holding portion 32 functions so as to protect the substrate holding portion 32 around the substrate holding portion 32. 32 can be protected. In addition, since a space is formed between the annular frame portion 34 and the substrate holding portion 32, if the case 3 is deformed due to an external impact or the like, a part of the case 3 becomes the frame portion 34. Even if it collides and the frame portion 34 is bent, the frame portion 34 is unlikely to interfere with the substrate holding portion 32 as long as it is bent in the space. In addition, when a part of the case 3 collides with the frame portion 34 and the frame portion 34 is bent, an effect of absorbing an impact force is surely generated while the frame portion 34 is displaced in the space. Even if the bent frame portion 34 reaches the substrate holding portion 32 and comes into contact with the substrate holding portion 32, the substrate holding portion 32 is hardly pushed by a strong force at the time of contact.

  Further, in this configuration, as shown in FIG. 5 and the like, the outer wall portion of the frame portion 34 opposite to the substrate holding portion 32 side is provided with a convex portion 80 that protrudes to the opposite side of the substrate holding portion 32 side. The convex portion 80 is disposed to face the inner wall portion of the case 3. Thus, if the convex part 80 is provided in the outer wall part of the frame part 34, and this convex part 80 is made the structure facing the inner wall part of the case 3, when a case 3 deform | transforms by external impact etc., a case will occur. 3 easily hits the vicinity of the convex portion 80, and interference to other than the convex portion 80 is easily suppressed.

  Further, in this configuration, the impact relaxation portion 38 is formed in the frame portion 34 and is a portion to be supported by the case 3 (convex portion 80), and the support portion (convex portion 80) in the frame portion 34. ) And a spring part (flexible deformation part 70) provided in a connected form. The connecting portion 36 is arranged to connect the substrate holding portion 32 to a portion of the frame portion 34 that is away from the support target portion (convex portion 80) and the spring portion (bending deformation portion 70). In this configuration, since at least the frame portion 34 is supported by the case 3, vibrations and impacts transmitted from the case 3 to the substrate holding portion 32 are compared with a configuration in which only the substrate holding portion 32 is supported by the case 3. It becomes easy to suppress. In addition, a spring part (flexure deformation part 70) is provided in a form connected to the support target part (convex part 80), and a part away from the support target part (convex part 80) and the spring part (flexure deformation part 70) is provided. Since the connection part 36 is provided in a connected form, the shock and vibration transmitted from the case 3 to the support target part (convex part 80) are easily mitigated before reaching the connection part 36, and the connection part 36 and It becomes easier to suppress vibrations and shocks to the connected substrate holding part 32.

  In addition, the impact relaxation portion 38 has a slit 90 formed in a cutout shape in the frame portion 34, and a bending deformation portion 70 that is disposed adjacent to the space of the slit 90 in the frame portion 34 and is configured to be elastically deformable. And. Then, the impact transmitted from the case 3 to the frame portion 34 is mitigated by the elastic deformation of the bending deformation portion 70. According to this configuration, it is possible to realize a structure capable of effectively mitigating impact, vibration, and the like with a simple configuration of the notched slit 90 and the bending deformation portion 70 adjacent thereto. In addition, since the notched slit 90 is formed not in the substrate holding portion 32 but in the frame portion 34, the rigidity of the substrate holding portion 32 is hardly lowered by this slit 90, and the rigidity in the vicinity of the circuit board 5 is kept high. It becomes easy.

  Further, the impact relaxation portion 38 includes a pair of slits 90 formed in the frame portion 34, and the bending deformation portion 70 is disposed between both spaces in the pair of slits 90. According to this configuration, with a simple configuration in which the bending deformation portion 70 is provided between the pair of slits 90, it is possible to realize a structure in which bending deformation is more likely to occur and the impact relaxation effect is high.

  Further, as shown in FIG. 3 and the like, the frame portion 34 is provided with a plurality of corner portions α formed by connecting two plate-like portions 40 respectively extending in different directions. A slit 90 is formed in a bent shape in a configuration that continuously continues from one plate-like portion 40 constituting the corner portion α to the other plate-like portion 40 adjacent thereto. And the bending deformation part 70 provided in each corner | angular part (alpha) is the structure by which a part of one plate-shaped part 40 and each part of the other plate-shaped part 40 which comprise each corner | angular part (alpha) were connected. And is arranged in a bent shape at a position adjacent to the space of the bent slit 90. According to this configuration, it is possible to reliably enhance the impact relaxation effect near the corner portion α where an impact is easily applied with a simple configuration. In addition, since the slit 90 is configured in a bent shape and the bending deformation portion 70 is disposed in a bending shape, a force is applied in a direction in which one plate-like portion 40 constituting the slit 90 and the bending deformation portion 70 extends. Even when the force is applied in the direction in which the other plate-like portion 40 extends or when the force is applied obliquely with respect to the direction in which both the plate-like portions 40 extend, the bending deformation portion 70 is easily elastically deformed. . Therefore, it is possible to effectively absorb impacts in various directions, and the direction of impacts that cannot be handled is reduced.

  More specifically, as shown in FIG. 3 and the like, the frame portion 34 is configured in a rectangular frame shape having four corner portions α, and the direction perpendicular to the plate surface of the circuit board 5 is the vertical direction. Each corner portion α has a configuration that continuously continues from one plate-like portion 40 constituting each corner portion α to the other plate-like portion 40 adjacent thereto and along a plane direction perpendicular to the vertical direction. Two slits 90 are formed in a pair in a configuration extending in a bent shape. And the bending deformation part 70 provided in each corner | angular part (alpha) is the structure by which a part of one plate-shaped part 40 and each part of the other plate-shaped part 40 which comprise each corner | angular part (alpha) were connected. And at a position between the pair of slits 90 is arranged in a configuration extending in a bent shape along a plane direction orthogonal to the vertical direction. Further, each of the bending deformation portions 70 provided at each of the four corner portions α includes a direction inclined with respect to the direction of the two plate-like portions 40 constituting each of the bending deformation portions 70 and the inside of the case 3. Protrusions extending toward the wall surface are formed, and each protrusion is configured to be held by the case 3. According to this configuration, in the frame portion 34 configured in a rectangular frame shape, the impact can be effectively reduced with a simple configuration for any of the four corner portions α where the impact is easily applied and the stress is easily concentrated. It can be.

  Further, at any corner α, the slit 90 is formed in a bent shape, and the bending deformation portion 70 is formed in a bent shape. For this reason, in any corner portion α, both the plate-like portions 40 are applied even when a force is applied in the direction in which one plate-like portion 40 extends or in a direction in which the other plate-like portion 40 extends. Even when a force is applied obliquely with respect to the extending direction, the bending deformation portion 70 is easily elastically deformed. That is, in any corner portion α, it is possible to effectively absorb impacts in various directions, and the types of impacts that cannot be handled as the entire frame portion 34 are further reduced.

  Furthermore, each bending deformation portion 70 configured in a bent shape near each corner portion α has a protruding portion (convex portion 80) inclined with respect to the direction of the plate-like portion 40. Since the case 3 is deformed by an external impact or the like, the case 3 is likely to hit the protruding portion (convex portion 80), and the deformation of the case 3 is further deformed by the bending deformation portion 70. It becomes easy to receive. In addition, since the projecting portion (convex portion 80) projects in an inclined direction with respect to the two plate-shaped portions 40, the case 3 is deformed so that the projecting portion (convex portion 80) may be any Even when a force is applied in the direction of the plate-shaped portion 40, an action of rotating the protruding portion (convex portion 80) is likely to occur, and this action causes each extension of the bending deformation portion 70 configured in a bent shape. It becomes easier to apply a force to bend the protruding part. That is, even when a force is applied from the case 3 to any plate-like portion 40 close to the protruding portion (convex portion 80) with respect to the vicinity of the tip of the protruding portion (convex portion 80), the bending deformation portion 70 side is set. The rotating action of the projecting portion (convex portion 80) serving as the base end portion is easily converted into a force in a direction in which the bending deformation portion 70 can easily absorb the impact, and thus the impact can be absorbed more effectively.

  For example, as shown in FIG. 14, the convex portions 81 a and 81 b (protruding portions) protrude in an inclined direction with respect to the two plate-like portions 41 and 44. Even when a force is applied in any direction of the plate-like portions 41 and 44 with respect to the vicinity of the tip end portion of the (projecting portion), an action to rotate the projecting portion (convex portion 80) is likely to occur. For example, when a force Fz1 in a direction along the direction of the plate-like portion 41 is applied to the convex portion 81a due to the deformation of the case 3, the convex portion 81a is easily rotated clockwise, thereby being configured to be bent. The bending deformation part 70 becomes easy to deform like Z1 and Z2. Further, when the force Fx1 in the direction along the direction of the plate-like portion 44 is applied to the convex portion 81a due to the deformation of the case 3, the convex portion 81a is easily rotated counterclockwise, and thus is bent. The bent deformation part 70 is easily deformed like X1 and X2. Further, when a force Fa opposite to the protruding direction of the convex portion 81a is applied to the tip portion of the convex portion 81a, the extended portion of the bending deformation portion 71 disposed obliquely with respect to the direction of the force is It becomes easy to deform. Thus, since it is easy to convert into the force of the direction which is easy to absorb an impact in the bending deformation part 71, an impact can be absorbed more effectively.

  Further, the connecting portion 36 is provided so as to connect a portion of the frame portion 34 that is out of the formation region of the slit 90 and the substrate holding portion 32. According to this configuration, the impact mitigating effect can be enhanced with a simple configuration, and the displacement and vibration of the portion (flexible deformation portion 70) that greatly contributes to the impact mitigation can be made difficult to be transmitted by the connection portion 36 and the substrate holding portion 32. it can.

  Further, the slit 90 is formed as a groove having a predetermined width and extends along a plane direction parallel to the direction of the plate surface of the circuit board 5 (see particularly FIG. 15). According to this configuration, deformation or restoration that causes at least the interval between the slits 90 to be increased or decreased is likely to occur, and at least force in a direction orthogonal to the plate surfaces 5a and 5b of the circuit board 5 is absorbed in the vicinity of the slit 90. In particular, the force in the direction that causes the circuit board 5 to bend is easily suppressed.

  When the direction orthogonal to the plate surface of the circuit board 5 is the vertical direction, the minimum vertical distance between the upper end portion of the combined body 2 and the inner plate surface of the upper wall portion of the case 3, and the combined body The minimum vertical distance between the lower end portion of 2 and the inner plate surface of the lower wall portion of the case 3 is larger than the width of the slit 90. In this configuration, even if the entire combined body 2 is relatively moved upward to the width of the slit 90 or relatively moved downward, the combined body 2 is unlikely to contact the upper wall portion or the lower wall portion of the case 3, It is easy to prevent contact with the case 3 due to relative movement, and the circuit board 5 and the like are more easily protected.

  Further, the impact relaxation portion 38 is formed to protrude toward the case 3 side in the frame portion 34 and is connected to a holding target portion (convex portion 80) that is a portion held by the case 3, and connected to the holding target portion in the frame portion 34. And a spring portion (flexible deformation portion 70) provided in the shape. The case 3 includes a case main body portion 3c that forms an outer shell of the case 3, and a holding portion 3d that is connected to the inside of the case main body portion 3c and serves as a portion that holds the combined body 2. When the direction orthogonal to the plate surface of the circuit board 5 is the vertical direction, the holding part 3d is configured to hold a part of the holding target part (convex part 80) sandwiched vertically. Thus, if the holding structure is configured such that the portion provided in the projecting structure in the frame portion 34 is sandwiched by a part of the case 3, when the case 3 is deformed or the like, the holding portion 3 b is held. Since the part easily swings and the force is easily released by such relative displacement, the impact absorbing effect is further enhanced.
