JP, 10-178290, A

The above electronic device may be mounted on a flat mounting surface. That is, for example, when the electronic device is a control device and is mounted on the back surface of the display of the panel-type PC. Here, if the slot insertion slot of the electronic device is oriented in a direction parallel to the mounting surface, the board is also generally inserted/removed along the direction parallel to the mounting surface.

The back surface of the above display may be attached to a sheet metal member. At this time, an opening is provided in the sheet metal member to avoid interference between the sheet metal member and the electronic device mounted on the back surface of the display. Therefore, when the back surface of the display is attached to the sheet metal member, the electronic device is located inside the opening provided in the sheet metal member. At this time, the electronic device is surrounded by the sheet metal member in a plan view, and the slot of the electronic device and the sheet metal member face each other. In that state, it is difficult to insert and remove the board along the direction parallel to the mounting surface because the sheet metal member facing the slot becomes an obstacle when inserting and removing the board. As described above, when the electronic device including the slot is mounted on the flat mounting surface on the back surface of the display, it may be difficult to insert and remove the substrate into and from the slot.

Therefore, it is an object of the present invention to provide an electronic device in which a substrate can be easily inserted and removed while avoiding the member even if the member is arranged around the insertion opening of the slot.

The present invention is an electronic device mounted on a flat mounting surface so as to face a member, wherein a slot into which a substrate is inserted/removed along an insertion/removal direction parallel to the mounting surface, and an insertion/removal of the substrate into/from the slot. A pair of guide rails extending into the slot along the insertion/removal direction on both surface sides of the substrate to be inserted into the slot, and the insertion of the slot into which the substrate is inserted/removed. The mouth is arranged so as to face the member, and the pair of guide rails is provided with an inclined surface that allows the substrate to be tilted so as not to come into contact with the member while the substrate is being inserted into or removed from the slot. Has been.

According to the present invention, the board can be tilted when the board is inserted into and removed from the slot. Therefore, even if a member is arranged around the insertion opening of the slot, the board can be easily inserted and removed while avoiding the member.

FIG. 9 is an internal side view of a slot of modification 1; FIG. 11 is an internal side view of a slot of modification 2; FIG. 11 is an internal side view of a slot of modification 3;

The electronic device of the present invention will be described below in detail with reference to the accompanying drawings, with reference to preferred embodiments.

[Embodiment]
FIG. 1 is a perspective view of a panel-type PC in which the electronic device 10 of the embodiment is mounted.

Hereinafter, the up, down, left, right, and front and rear directions will be described with reference to the arrows shown in FIG. The electronic device 10 according to the present embodiment is a numerical controller, and is mounted on the flat mounting surface 14 of the display 12. The display device 12 is a display device in the present embodiment, and has a screen such as a liquid crystal screen on the lower surface. The mounting surface 14 is a surface (back surface) on the upper side of the display 12 in the present embodiment. The electronic device 10 according to the present embodiment can be mounted on the mounting surface 14 to control the display 12. That is, the electronic device 10 can display the progress and result of the arithmetic processing executed by the electronic device 10 on the display device 12.

The display 12 is attached to the sheet metal 16 having a vertical thickness on the mounting surface 14 side. The sheet metal 16 is provided with an opening 16a. The opening 16a of the sheet metal 16 is provided to prevent the electronic device 10 mounted on the back surface of the display 12 and the sheet metal 16 from interfering with each other when the back surface of the display 12 is attached to the sheet metal 16. It is what is done. As shown in FIG. 1, when the display 12 is attached to the sheet metal 16, the electronic device 10 is located inside the opening 16 a. As a result, the electronic device 10 is in a state of being surrounded by the sheet metal 16 in a plan view. Hereinafter, the sheet metal 16 is also referred to as the member 16.

The electronic device 10 is provided with a slot structure 20 for mounting a substrate 18 on which an electric circuit is formed. The slot structure 20 has a slot 22 in which the board 18 is stored, and a pair of guide rails 24 that extend along the front-rear direction (insertion/removal direction) parallel to the mounting surface 14 on both surface sides of the board 18. A connector (not shown) is provided at the rear end of the slot 22 so that it can be fitted and connected to the connector 18a of the board 18 inserted into the slot 22.

As shown in FIG. 1, the pair of guide rails 24 are provided in the slot 22 so as to be located at both ends of the board 18 in a direction intersecting the front-back direction (left-right direction). As a result, it is easier to guide the surface of the board 18 into the back of the slot 22 in a state in which the surface of the board 18 is parallel to the insertion/removal direction as compared with the case where the pair of guide rails 24 are provided only on one end side of the board 18 in the left-right direction. Becomes

Further, the pair of guide rails 24 has a first rail 26 located relatively on the upper side and a second rail 28 located relatively on the lower side. The first rail 26 and the second rail 28 are separated from each other with a gap larger than the thickness of the substrate 18.

Here, the member 16 having a vertical thickness may become an obstacle when the substrate 18 is inserted into and removed from the slot 22. In order to insert and remove the board 18, it is possible to temporarily remove the electronic device 10 from the mounting surface 14. However, it is inefficient to perform the attachment/detachment work to/from the mounting surface 14 of the electronic device 10 only for inserting/removing the substrate 18. Therefore, in the present embodiment, as described below, even if the member 16 is arranged on the mounting surface 14 so as to face the insertion opening 30 of the slot 22, the substrate 18 is inserted and removed while avoiding the member 16. To be able to.

FIG. 2 is an internal side view of the slot 22 of the embodiment.

The pair of guide rails 24 are provided with inclined surfaces 32 that allow the board 18 to be tilted so as not to come into contact with the member 16 while the board 18 is being inserted into or removed from the slot 22. In the present embodiment, as shown in FIG. 2, the inclined surface 32 is provided at the tip of the first rail 26 of the pair of guide rails 24. Since the inclined surface 32 is provided on the first rail 26, it is possible to incline the substrate 18 so that the rear side thereof faces upward while the substrate 18 is being inserted into or removed from the slot 22.

As shown in FIG. 2, the first rail 26 has a lower flat surface 26a extending in the front-rear direction, and the second rail 28 has an upper flat surface 28a extending in the front-rear direction. .. As a result, for example, when the substrate 18 is inserted into the slot 22 while the substrate 18 is inserted while being tilted as described above, the front end of the substrate 18 eventually comes into contact with the flat surface 28a and bends. Mu. By inserting the board 18 as it is, the flat surface 26a and the flat surface 28a located on both surface sides of the board 18 gradually bring the board 18 closer to a state parallel to the front-rear direction (insertion/removal direction), and the back of the slot 22. Be guided to.

The inclination angle θ of the inclined surface 32 is preferably set so that the extension line B extending along the inclination angle θ of the inclined surface 32 and the member 16 do not intersect. Accordingly, the substrate 18 can be inserted into and removed from the slot 22 while the substrate 18 is tilted so as not to contact the member 16. Here, the inclination angle θ means the magnitude of the inclination of the inclined surface 32 with respect to the mounting surface 14 (the angle formed by the extension line B and the mounting surface 14) as shown in FIG. 2. In addition, here, the extension line B is an imaginary straight line in which both ends (front end and rear end) in the insertion/removal direction of the inclined surface 32 are placed on the line, as shown in FIG. It means that.

Further, the inclination angle θ may be set according to the distance A between the slot 22 and the member 16. For example, it can be said that the larger the distance A is, the less the necessity of inclining the substrate 18 with respect to the front-back direction (insertion/removal direction) becomes. Therefore, the larger the distance A, the smaller the inclination angle θ may be set. Further, the inclination angle θ may be set according to the length (height) of the member 16 in the vertical direction. For example, it can be said that the lower the height of the member 16 is, the less the necessity of inclining the substrate 18 with respect to the front-back direction (insertion/removal direction) becomes. Therefore, the lower the height of the member 16, the smaller the inclination angle θ may be set.

As described above, according to the slot structure 20 described above, even if there is the member 16 facing the insertion port 30 in the direction parallel to the mounting surface 14 (front-back direction), the substrate 18 is avoided while avoiding the member 16. It can be easily inserted into and removed from the slot 22.

The slot structure 20 is not limited to the one provided in the control device of the panel type PC. Although the inclined surface 32 is provided only on the first rail 26 in the above description, the inclined surface 32 may be provided not only on the first rail 26 but also on the second rail 28. Further, in FIGS. 1 and 2, the case where one electronic device 10 has one slot structure 20 has been described for the sake of simplicity. Not limited to this, two or more slot structures 20 described above may be provided for each electronic device 10.

[Modification]
Although the embodiment has been described as an example of the present invention, it is needless to say that various modifications and improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

(Modification 1)
FIG. 3 is an internal side view of the slot 22 of the first modification.

The second rail 28 may be provided with a recess 34 that extends in the front-rear direction and that suppresses bending of the substrate 18 when the substrate 18 is inserted into or removed from the slot 22. FIG. 3 shows a recess 34 having a rectangular cross section. The concave portion 34 is on the extension line B of the inclined surface 32 provided on the first rail 26, and the end portion 34 a of the concave portion 34 on the side of the insertion port 30 is located at an insertion port 30 which is more than the intersection point P between the extension line B and the concave portion 34. It is preferably provided so as to be located on the side. Thus, when the board 18 is inserted, the flexure of the board 18 when it comes into contact with the flat surface 28a of the second rail 28 can be absorbed by the recess 34. As a result, for example, the possibility that the substrate 18 is damaged due to excessive bending is reduced.

(Modification 2)
FIG. 4 is an internal side view of the slot 22 of the second modification.

The recess 34 need not have a rectangular cross section. For example, as shown in FIG. 4, the surface of the recess 34 may be a curved surface. Further, in the recess 34 of the present modified example, as in the case of the first modified example, the extended line B of the inclined surface 32 provided on the first rail 26 and the end 34a of the recess 34 on the insertion port 30 side are extended lines. It is preferably provided so as to be located closer to the insertion port 30 side than the intersection P of B and the recess 34. Thus, when the board 18 is inserted, the flexure of the board 18 when it comes into contact with the flat surface 28a of the second rail 28 can be absorbed by the recess 34. Further, since the concave portion 34 of the present modification has a curved surface, as compared with the concave portion 34 of the modification 1 having a rectangular cross section, when the substrate 18 is inserted and removed, the concave portion 34 on the front side or the rear side is formed. The substrate 18 is unlikely to be caught at the end of the. Therefore, according to this modification, the board 18 can be inserted into and removed from the slot 22 more smoothly than in the modification 1.

(Modification 3)
FIG. 5 is an internal side view of the slot 22 of Modification 3.

As shown in FIG. 5, the concave portion 34 may have a tapered cross-section with a side surface in the front-rear direction having a gradient. Similarly to Modifications 1 and 2, in the recess 34 of this modification, the end 34a of the recess 34 on the insertion port 30 side is on the extension line B of the inclined surface 32 provided on the first rail 26. It is preferably provided so as to be located closer to the insertion port 30 side than the intersection P of B and the recess 34. Thus, when the board 18 is inserted, the flexure of the board 18 when it comes into contact with the flat surface 28a of the second rail 28 can be absorbed by the recess 34. Further, the concave portion 34 of the present modified example has a side surface in the front-rear direction that is inclined, so that when compared to the concave portion 34 of the modified example 1 having a rectangular cross section, the concave portion 34 has a front side when the board 18 is inserted and removed. Alternatively, the substrate 18 is unlikely to be caught at the end of the recess 34 on the rear side. Therefore, according to this modification, the board 18 can be inserted into and removed from the slot 22 more smoothly than in the modification 1.

(Modification 4)
The length C of the inclined surface 32 in the front-back direction (insertion/removal direction) (hereinafter, also referred to as “the length C of the inclined surface 32”) may be appropriately set according to the distance A described above. Further, the length C of the inclined surface 32 may be appropriately set according to the length (height) of the member 16 in the vertical direction.

For example, the length C of the inclined surface 32 may be set longer as the distance A is smaller. This allows the board 18 to be inserted into the slot 22 with the board 18 tilted.

In addition, when the thickness of the first rail 26 and the second rail 28 in the vertical direction is set to be constant, the inclination angle θ is set larger as the distance A is smaller, and the length of the inclined surface 32 is smaller. Note that setting C to be long has a trade-off relationship. This is because, when the thickness of the first rail 26 and the second rail 28 in the vertical direction is fixed, when the inclination angle θ is determined, the length C of the inclined surface 32 is naturally determined accordingly.

(Modification 5)
The inclined surface 32 may be a surface whose inclination angle θ changes stepwise along the front-rear direction (insertion/removal direction). For example, the inclined surface 32 provided on the first rail 26 is provided with an inclination angle θ1 from the tip end portion of the first rail 26 to the middle in the forward direction, and the inclination angle 32 from the middle to the flat surface 26a. The inclination angle θ2 may be smaller than θ1. At this time, the extension line B that does not intersect the member 16 may be defined only for at least one of the inclination angle θ1 and the inclination angle θ2.

(Modification 6)
The inclined surface 32 may be a curved surface instead of a flat surface. At this time, the extension line B may be defined as an imaginary straight line having both ends in the insertion/removal direction of the inclined surface 32 on the line, as described in the above embodiment. Further, the angle formed by the extension line B and the mounting surface 14 may be treated as the inclination angle θ of the inclined surface 32.

(Modification 7)
The above-described embodiment and each modified example may be appropriately combined within a range in which no contradiction occurs.

It

The inclination angle (θ) of the inclined surface (32) may be set according to the distance (A) between the slot (22) and the member (16). As a result, the maximum inclination allowed by the inclined surface (32) is determined according to the distance (A) between the slot (22) and the member (16), and thus the substrate can reach the maximum inclination allowed by the inclined surface (32). By tilting (18), it is possible to reduce the risk that the substrate (18) and the member (16) will come into contact with each other when the slot (22) is inserted and removed.

The second rail (28) has a recess (34) extending in the insertion/removal direction for suppressing the bending of the substrate (18) when the substrate (18) is inserted into or removed from the slot (22).

It becomes easy to make them parallel and guide them to the back of the slot (22).

The mounting surface (12) may be a back surface of a display (12) having a screen, and the electronic device (10) may be a control device capable of controlling the display (12). The member (16) may be a metal plate to which the display (12) is attached.
