Description

The present invention relates to a card reader provided with a card insertion slot in the case.

When using the card reader in an environment where liquid is scattered, the liquid may get caught in the card insertion slot. If liquid enters the inside of the card reader through the card insertion slot, the liquid may splash on the board on which the electronic components are mounted, causing a malfunction. Therefore, a structure has been proposed for avoiding a problem caused by the infiltration of liquid from the card insertion slot.

Patent Document 1 discloses a card reader in which a card insertion slot is covered with a transparent cover. The transparent cover is rotatably attached to the main body case of the card reader, and when the card is inserted into the card insertion slot, the transparent cover is manually rotated to open and close. Further, Patent Document 2 discloses a card processing device in which a drainage hole is provided in a front bezel provided with a card insertion slot. In the card processing apparatus of Patent Document 2, the bottom of the case is inclined. The water that has entered from the card insertion slot drops onto the bottom of the case and is guided to the drain hole along the inclined portion to be discharged.

Japanese Unexamined Patent Publication No. 6-44395 Japanese Patent No. 5088831

When the card insertion slot is covered with a transparent cover as in Patent Document 1, it takes time and effort to insert the card because the transparent cover needs to be opened and closed when the card is inserted. Further, there is a possibility that the liquid may be splashed at the timing when the cover is opened, and in this case, the liquid may infiltrate into the inside through the card insertion slot. Therefore, there is a possibility that a problem may occur due to the infiltration of liquid.

On the other hand, in Patent Document 2, the liquid that has entered from the card insertion slot can be discharged from the drain hole. However, in Patent Document 1, the liquid that has entered from the card insertion slot may catch on parts or the like and flow in a direction different from the drain hole while falling to the bottom of the case, and the liquid may flow to a place where it cannot be drained from the drain hole. There is a risk of intrusion. Therefore, there is a possibility that a problem may occur due to the liquid accumulated inside the case.

In view of the above problems, an object of the present invention is to suppress a defect caused by liquid entering from the card insertion slot in a card reader provided with a card insertion slot in the case.

In order to solve the above problems, the card reader of the present invention has a card processing unit and a case body for accommodating the card processing unit, and the case body has a card in a card passage provided in the card processing unit. A card insertion slot for inserting the card and a drainage hole for draining the liquid that has entered the inside of the case body are provided, and the inside of the case body is provided from the card insertion slot to the inside of the case body. A partition member for guiding the infiltrated liquid to the drain hole is provided, and the partition member includes a first end portion extending toward the drain hole, and the first end portion is a first portion. A second portion shorter than the first portion is provided, and the tip of the second portion is inclined in a downward direction toward the side of the first portion .

In the present invention, the case body of the card reader is provided with a drainage hole, and a partition wall member is provided to guide the liquid that has entered the inside of the case body from the card insertion slot to the drainage hole. Therefore, even if the liquid enters the inside of the case body from the card insertion slot, the liquid can be guided to the drain hole by the partition wall member. Therefore, the liquid can be efficiently discharged from the drain hole. In addition, the partition wall member can regulate the infiltration of liquid into a place away from the drain hole. Therefore, there is little possibility that the liquid will infiltrate into the position where the liquid cannot be discharged from the drain hole. Therefore, it is possible to suppress the occurrence of defects due to the infiltration of liquid. Further, the liquid hung on the partition wall member can be collected in the first portion, and can be guided to the drain hole through the first portion. Therefore, the liquid hung on the partition wall member can be efficiently guided to the drain hole and efficiently discharged.

In the present invention, it is preferable that the partition wall member is arranged so as to surround the card processing portion. By doing so, it is possible to restrict the infiltration of the liquid into a position away from the card insertion slot through the circumference of the card processing unit. Therefore, since it is possible to regulate the infiltration of the liquid into the back of the case body, there is little possibility that the liquid will be caught on the parts arranged in the back of the case body and a problem will occur.

In the present invention, the bottom of the case body is provided with the drainage hole and a regulation wall located on the opposite side of the drainage hole from the card insertion slot, and the upper end of the regulation wall is the above. It is preferably located above the drain hole. By doing so, it is possible to restrict the liquid that has flowed down to the bottom of the case body from flowing to the inner side of the case body. In addition, the liquid can flow into the drain hole before it crosses the regulation wall. Therefore, there is little possibility that the liquid will not be able to return to the drain hole beyond the regulation wall, and therefore there is little possibility that the liquid will not be able to be discharged.

Next, the card reader of the present invention has a card processing unit and a case body for accommodating the card processing unit, and the case body is for inserting a card into a card passage provided in the card processing unit. It is provided with a card insertion slot and a drain hole for draining the liquid that has entered the inside of the case body, and the liquid that has entered the inside of the case body from the card insertion slot is said to be inside the case body. A partition wall member for guiding to the drainage hole is provided, and the case body includes a front cover on which the card insertion slot is formed and a case body having an opening to which the front cover is attached, and the case body is provided with the drainage. The liquid hole is characterized in that it is provided at the joint between the front cover and the case body. By doing so, even if the liquid enters the inside of the case body from the card insertion slot, the liquid can be guided to the drain hole by the partition wall member. Therefore, the liquid can be efficiently discharged from the drain hole. In addition, the partition wall member can regulate the infiltration of liquid into a place away from the drain hole. Therefore, there is little possibility that the liquid will infiltrate into the position where the liquid cannot be discharged from the drain hole. Therefore, it is possible to suppress the occurrence of defects due to the infiltration of liquid. Further, it is not necessary to form a through hole in the case body in order to form a drainage hole. Therefore, it is possible to avoid complicating the shape of the parts constituting the case body.

In the present invention, the front cover is provided with a convex portion bulging toward the outer peripheral side from the opening of the case body, and the drainage hole is provided between the convex portion and the case main body, and the convex portion is provided. It is possible to adopt a configuration in which the drainage hole is divided into a plurality of holes by a plurality of ribs formed on the inside. In this way, the drainage hole can be formed by assembling the front cover and the case body. Further, since the drainage hole is partitioned by the rib, there is little possibility that foreign matter enters through the drainage hole.

In the present invention, the partition wall member is provided with a second end portion extending upward of the card processing portion, the second end portion is provided with a bent portion, and the folded portion is referred to as the card insertion slot toward the upper side. It is preferable to incline in the direction toward the opposite side. In this way, the liquid that infiltrates through the seam can be received at the bent portion and guided to the side of the card insertion slot. Therefore, there is little possibility that the liquid that infiltrates through the seam will flow into the back of the case body.

Next, the card reader of the present invention has a card processing unit and a case body for accommodating the card processing unit, and the case body is for inserting a card into a card passage provided in the card processing unit. It is provided with a card insertion slot and a drain hole for draining the liquid that has entered the inside of the case body, and the liquid that has entered the inside of the case body from the card insertion slot is said to be inside the case body. A partition member for guiding to the drainage hole is provided, and the case body is provided with a shelter formed on the upper side of the card insertion slot, and a lateral rib protruding from the surface of the shelter is provided along the tip of the shelter. The lateral ribs are continuously extended and are characterized in that the lateral ribs have a shape that descends toward both sides in the width direction of the card insertion slot. By doing so, even if the liquid enters the inside of the case body from the card insertion slot, the liquid can be guided to the drain hole by the partition wall member. Therefore, the liquid can be efficiently discharged from the drain hole. In addition, the partition wall member can regulate the infiltration of liquid into a place away from the drain hole. Therefore, there is little possibility that the liquid will infiltrate into the position where the liquid cannot be discharged from the drain hole. Therefore, it is possible to suppress the occurrence of defects due to the infiltration of liquid. Further, there is little possibility that the liquid hung on the eaves will flow down the back side of the eaves and flow into the card insertion slot. Therefore, when the card reader is used in an environment where the liquid is scattered, it is possible to prevent the liquid from entering the card insertion slot. Further , since the liquid dammed by the horizontal ribs flows down to both sides in the width direction of the card insertion slot, it is possible to prevent the liquid caught on the eaves from flowing into the card insertion slot.

In the present invention, the case body includes a guide surface formed under the card insertion slot.
The guide surface is preferably an inclined surface that goes downward as the distance from the card insertion slot increases. By doing so, it is possible to prevent the liquid hung on the guide surface from flowing down the guide surface and into the card insertion slot.

According to the present invention, the case body of the card reader is provided with a drainage hole, and a partition wall member is provided to guide the liquid that has entered the inside of the case body from the card insertion slot to the drainage hole. Therefore, even if the liquid enters the inside of the case body from the card insertion slot, the liquid can be guided to the drain hole by the partition wall member. Therefore, the liquid can be efficiently discharged from the drain hole. In addition, the partition wall member can regulate the infiltration of the liquid into a place away from the drain hole. Therefore, there is little possibility that the liquid will infiltrate into the position where the liquid cannot be discharged from the drain hole. Therefore, it is possible to suppress the occurrence of defects due to the infiltration of liquid.
Further, the liquid hung on the partition wall member can be collected in the first portion, and can be guided to the drain hole through the first portion. Therefore, the liquid hung on the partition wall member can be efficiently guided to the drain hole and efficiently discharged.
Alternatively, it is not necessary to form a through hole in the case body in order to form a drainage hole. Therefore, it is possible to avoid complicating the shape of the parts constituting the case body.
Alternatively, there is little risk that the liquid on the eaves will flow down the back side of the eaves and into the card insertion slot. Therefore, when the card reader is used in an environment where the liquid is scattered, it is possible to prevent the liquid from entering the card insertion slot. Further, since the liquid dammed by the horizontal ribs flows down to both sides in the width direction of the card insertion slot, it is possible to prevent the liquid caught on the eaves from flowing into the card insertion slot.

It is a perspective view of the card reader to which this invention is applied. 1 is a cross-sectional view and a partially enlarged cross-sectional view of the card reader of FIG. It is a front view and a side view of a front cover. It is the perspective view which looked at the front cover and the waterproof sheet from the rear, and the rear view which looked at the front cover from the rear. It is the perspective view of the card reader which omitted the front cover, and the perspective view of the waterproof sheet. It is a perspective view of a lower case.

Hereinafter, embodiments of a card reader to which the present invention is applied will be described with reference to the drawings.

(overall structure)
FIG. 1 is a perspective view of a card reader 1 to which the present invention is applied, and FIG. 2 is a cross-sectional view and a partially enlarged cross-sectional view of the card reader 1 of FIG. As shown in FIG. 1, the card reader 1 is formed in a rectangular parallelepiped box shape as a whole. As shown in FIG. 2, the card reader 1 includes a case body 3 and a card processing unit 4 housed in the case body 3. As shown in FIGS. 1 and 2, a card insertion slot 5 is formed on the front surface of the case body 3. As shown in FIG. 2, the card processing unit 4 is provided with a card passage 6. Magnetic data is recorded on the card 2, and the card 2 is inserted into the card passage 6 through the card insertion slot 5. The card processing unit 4 takes in the card 2 at a predetermined position in the card passage 6, performs a predetermined process such as reading or writing magnetic data, and ejects the card from the card insertion slot 5. As shown in FIG. 1, on the upper side of the card insertion slot 5, an LED display unit 7 is provided at a corner between the front surface and the upper surface of the case body 3.

In the present specification, the three directions of XYZ are directions orthogonal to each other. The X direction is the front-back direction of the card reader 1. Inside the card reader 1, the card passage 6 extends in the X direction. The X1 direction is in front of the card passage 6 and is the side on which the card insertion slot 5 is located. The X2 direction is the back side (rear side) of the card passage 6. The Y direction is the width direction of the card insertion slot 5. Of one side and the other side of the width direction Y, the right side when the card reader 1 is viewed from the front X1 is the one side Y1, and the left side is the other side Y2. Further, the Z direction is the vertical direction of the card reader 1. The Z1 direction is the upper side, and the Z2 direction is the lower side. Inside the case body 3, a space is provided between the upper side Z1 and the lower side Z2 of the card processing unit 4 with the case body 3. A power supply device (not shown) or the like is arranged in the space of the lower Z2 of the card processing unit 4.

The case body 3 includes a case body 31 that houses the card processing unit 4 and a front cover 32 that is attached to the end of the front X1 of the case body 31. The case body 31 can be divided into two in the vertical direction Z, and includes an upper case 33 and a lower case 34. When the upper case 33 and the lower case 34 are assembled, a case body 31 having an opening 35 facing forward X1 (see FIG. 5A) is formed. The front cover 32 is attached so as to close the opening 35 of the case body 31. A hook 36 (see FIGS. 2 (b) and 5 (a)) projecting forward X1 is formed on the edge of the upper side Z1 of the opening 35. An engaging recess 37 (see FIG. 2B) that engages with the hook 36 is formed on the upper end edge of the front cover 32.

(Outside shape of card insertion slot 5)
FIG. 3A is a front view of the front cover 32, and FIG. 3B is a side view of the front cover 32. As shown in FIGS. 1 and 3A, the front cover 32 is formed with a card insertion slot 5 extending in a slit shape in the Y direction. The lower Z2 of the card insertion slot 5 is formed with a lower protruding portion 51 projecting forward X1. A lower recess 52 recessed in the rear X2 is formed at the center of the lower protrusion 51 in the width direction Y. Since the lower recess 52 is provided, the card 2 can be inserted all the way into the card insertion slot 5 when the card 2 is manually inserted.

The upper surface of the lower protrusion 51 is a guide surface 53 that guides the card 2 toward the card insertion slot 5. Since the card 2 inserted into the card insertion slot 5 faces the card insertion slot 5 along the guide surface 53, the card 2 can be easily inserted. As shown in FIG. 2B, the guide surface 53 is an inclined surface toward the lower side Z2 toward the front X1. In other words, the guide surface 53 is an inclined surface toward the lower side Z2 as the distance from the card insertion slot 5 increases. Therefore, even if the liquid is splashed on the guide surface 53, the liquid flows down to the front X1 instead of the side of the card insertion slot 5, so that there is little possibility that the liquid will flow into the card insertion slot 5.

The front cover 32 is formed with eaves 54 that surround the upper side Z1 of the card insertion slot 5 and both sides in the width direction Y. The eaves 54 project from the front surface of the front cover 32 toward the front X1. The eaves 54 are formed by the eaves upper portion 55 formed on the upper side Z1 of the card insertion slot 5, the eaves right side portion 56 connected to the end of the eaves upper portion 55 on one side Y1 in the width direction Y, and the eaves upper portion 55 in the width direction Y. The eaves left side portion 57 connected to the end portion of the other side Y2 is provided. The eaves right side portion 56 and the eaves left side portion 57 extend in the vertical direction Z on one side Y1 and the other side Y2 of the card insertion slot 5 in the width direction Y, and extend to the outside of the width direction Y of the lower protrusion 51. There is. The surface of the lower Z2 of the eaves upper portion 55 is an inclined surface 551 (see FIG. 2B) toward the upper side Z1 toward the front X1. At the center of the inclined surface 551 in the width direction Y, an upper recess 58 recessed in the rear X2 and the upper Z1 is formed.

A lateral rib 59 is formed at the tip of the eaves upper portion 55. The lateral rib 59 projects forward X1 from the surface of the tip of the eaves upper part 55, and continuously extends in the width direction Y along the tip of the eaves upper part 55. One end of the lateral rib 59 extends to the right side of the eaves 56, and the other end extends to the left side of the eaves 57. The tip of the eaves upper portion 55 has a curved shape in which the center in the width direction Y bulges toward the upper side Z1. The lateral rib 59 has a shape along the tip of the eaves upper portion 55, and has a shape of descending toward both sides in the width direction Y. Both ends of the lateral rib 59 extend to the outside of the card insertion slot 5 in the width direction Y. When the liquid is applied to the eaves 54, the liquid flows along the surface of the eaves 54 toward the tip of the eaves 54, but at the tip of the eaves 54, the liquid is dammed by the lateral ribs 59 and the eaves 54 are dammed along the lateral ribs 59. It flows toward both sides in the width direction Y. Therefore, since the horizontal rib 59 suppresses the liquid from flowing into the card insertion slot 5 along the back side of the eaves 54, there is little possibility that the liquid will flow into the card insertion slot 5.

(Waterproof sheet)
FIG. 4A is a perspective view of the front cover 32 and the waterproof sheet 8 as viewed from the rear, and FIG. 4B is a rear view of the front cover 32 as viewed from the rear.

Will be done. That is, the waterproof sheet 8 is arranged so as to partition the space between the card processing unit 4 and the case body 3 back and forth on the entire circumference. The rectangular hole 81 is formed so that the card processing portion 4 fits without a gap. Therefore, when the liquid is splashed on the card insertion slot 5 from the outside and the liquid enters the inside of the case body 3 through the gap between the card processing unit 4 and the card insertion slot 5, the waterproof sheet 8 is the entire card processing unit 4. Prevents liquid from entering the rear X2 at the circumference.

As shown in FIG. 5B, the waterproof sheet 8 includes a sheet body 83 that is substantially perpendicular to the front-rear direction X, and a folded portion 84 that is connected to the upper end of the sheet body 83. The rectangular hole 81 is formed at the upper end of the sheet body 83. The bent portion 84 is formed by bending the portion of Z1 above the rectangular hole 81 diagonally rearward. The bent portion 84 is bent along a folded line 841 extending in the width direction Y, and the folded line 841 extends from the upper end edge of the rectangular hole 81 to both sides in the width direction Y. The bent portion 84 is inclined in the direction toward the rear X2 toward the upper side Z1.

As shown in FIG. 2B, the sheet body 83 of the waterproof sheet 8 is located in front X1 with respect to the seam 38 between the front cover 32 and the case body 31. On the other hand, the upper end of the bent portion 84 is located rearward X2 with respect to the seam 38. That is, the waterproof sheet 8 is arranged so that the seam 38 and the folded portion 84 overlap when viewed from the vertical direction Z. Therefore, when the liquid hung on the upper surface of the card reader 1 penetrates into the inside of the case body 3 from the seam 38, the liquid dripping from the seam 38 on the upper side Z1 of the card processing unit 4 is the folded portion 84 of the waterproof sheet 8. And flows down to the front X1 of the waterproof sheet 8.

The waterproof sheet 8 includes a first end portion 85 extending to the lower Z2 of the card processing unit 4 and a second end portion 86 extending to the upper Z1. The second end portion 86 includes the above-mentioned bent portion 84, and the first end portion 85 is a lower end portion of the seat body 83. The first end portion 85 includes two first portions 87 extending to reach the bottom of the case body 3 and a second portion 88 shorter than the first portion 87 in the Z direction. The first portion 87 and the second portion 88 are provided adjacent to each other in the Y direction. The lower end (tip) of the second portion 88 is provided on one side Y1 of the central portion 881 extending in the width direction Y between the two first portions 87 and the width direction Y of the two first portions 87. The first inclined portion 882 is provided, and the second inclined portion 883 provided on the other side Y2 of the two first portions 87 in the width direction Y is provided. The first inclined portion 882 and the second inclined portion 883 are inclined in the direction in which the length in the Z direction increases toward the first portion 87, respectively. In other words, the first inclined portion 882 and the second inclined portion 883 are inclined in the descending direction toward the first portion 87, respectively. Therefore, when the waterproof sheet 8 is splashed with the liquid, the liquid splashed on the second portion 88 is collected at the first portion 87 through the first inclined portion 882 and the second inclined portion 883.

As shown in FIG. 2B, the first end portion 85 of the waterproof sheet 8 is located in front of the seam 38 between the front cover 32 and the case body 31 X1. The inflow portion 391 of the drainage hole 39 opens at the bottom of the case body 3. The inflow portion 391 opens with a predetermined width in the front-rear direction X over a range from the seam 38 to a predetermined position of the front X1 thereof. The first end portion 85 is arranged at a position overlapping the inflow portion 391 when viewed from the vertical direction Z, and the two first portions 87 provided on the first end portion 85 extend to the inflow portion 391. .. Therefore, the liquid hung on the waterproof sheet 8 is collected in the first portion 87 and flows down from the first portion 87 to the inflow portion 391, so that the liquid hung on the waterproof sheet 8 is efficiently guided to the drain hole 39 for efficiency. Can be discharged as a target.

Therefore, even if the liquid enters the inside of the case body 3 from the card insertion slot 5, the liquid can be guided to the drain hole 39 by the waterproof sheet 8. Therefore, the liquid can be efficiently discharged from the liquid drain hole 39. Further, since the waterproof sheet 8 can regulate the infiltration of the liquid into the position away from the drain hole 39, there is little possibility that the liquid infiltrates into the position where the liquid cannot be discharged from the drain hole 39. Therefore, it is possible to suppress the occurrence of defects due to the infiltration of liquid.

In the present embodiment, the waterproof sheet 8 has a space between the card processing unit 4 and the case body 3 on the side where the card insertion slot 5 is located (front X1) and the side opposite to the card insertion slot 5 (rear X2). It is partitioning. Further, the waterproof sheet 8 surrounds the card processing unit 4 on the entire circumference. Therefore, since it is possible to restrict the infiltration of the liquid into the inner part of the case body 3, there is less possibility that the liquid will be caught on the parts arranged in the inner part of the case body 3 and cause a problem.

In the present embodiment, the waterproof sheet 8 has two first portions 87 and a second portion 88 shorter than the first portion 87 formed at the first end portion 85 extending toward the drain hole 39, and the second portion. The tip of the 88 comprises a first tilted portion 882 and a second tilted portion 883 that incline in a descending direction toward the side of the first portion 87. Therefore, the liquid hung on the waterproof sheet 8 can be collected in the first portion 87, and can be guided to the drain hole 39 through the first portion 87. Therefore, the liquid hung on the waterproof sheet 8 can be efficiently guided to the drain hole 39 and efficiently discharged.

In the present embodiment, the bottom of the case body 3 is provided with a drainage hole 39 and a regulation wall 345 located on the opposite side (rear X2) of the card insertion slot 5 with respect to the drainage hole 39, and the regulation wall 345 is provided. The upper end of is located in Z1 above the drain hole 39. Therefore, it is possible to restrict the liquid that has flowed down to the bottom of the case body 3 from flowing to the inner side of the case body 3. Further, since the liquid flows out from the drain hole 39 before it crosses the regulation wall 345, there is little possibility that the liquid cannot return to the drain hole 39 beyond the regulation wall 345.

In this embodiment, a drainage hole 39 is provided at the joint between the front cover 32 and the case body 31. Specifically, the front cover 32 is provided with a convex portion 10 bulging toward the outer peripheral side from the opening 35 of the case main body 31, and the drainage hole 39 is provided between the convex portion 10 and the case main body 31. When the drain hole 39 is formed in this way, the drain hole 39 can be formed by assembling the front cover 32 and the case main body 31. Therefore, since it is not necessary to form a through hole in the case body 3 in order to form the drainage hole 39, it is possible to avoid complicating the shape of the component forming the case body 3. Further, the drainage hole 39 is divided into a plurality of holes 393 by a plurality of ribs 16 formed inside the convex portion 10. Therefore, there is little possibility that foreign matter such as insects enters from the drain hole 39.

In the present embodiment, the waterproof sheet 8 includes a folded portion 84 extending upward of the card processing portion 4, and the folded portion 84 is inclined in a direction opposite to the card insertion slot 5 (rearward X2) toward the upper side Z1. are doing. As a result, the waterproof sheet 8 not only receives the liquid that enters from the side of the card insertion slot 5, but also receives the liquid that enters from the joint between the front cover 32 and the case body 31 at the bent portion 84, and the card insertion slot 5 receives the liquid. It is possible to guide to the side (front X1). Therefore, there is little possibility that the liquid that infiltrates through the seam will flow into the inner side of the case body 3.

In this embodiment, the front cover 32 is provided with an eaves 54 on the upper side of the card insertion slot 5, and a lateral rib 59 is formed at the tip of the eaves 54. Further, the lateral rib 59 has a shape that descends toward both sides in the width direction of the card insertion slot 5. Therefore, since the liquid flowing on the surface of the eaves 54 flows down to both sides in the width direction of the card insertion slot 5, the horizontal rib 59 can regulate the liquid hanging on the eaves 54 from flowing through the eaves 54 to the card insertion slot 5. .. Further, the front cover 32 is provided with a guide surface 53 on the lower side of the card insertion slot 5, and the guide surface 53 is an inclined surface toward the lower side Z2 toward the front X1. Therefore, even if the liquid is splashed on the guide surface 53, the liquid flows down to the front X1 instead of the side of the card insertion slot 5. Therefore, when the card reader is used in an environment where the liquid is splashed, it is possible to prevent the liquid from entering the card insertion slot.

(Modification example)
In the above embodiment, the rib 16 is formed in the drain hole 39 to prevent foreign matter from entering. However, a valve is provided in the outflow portion 392 of the drain hole 39, and the valve is formed when a certain amount or more of the liquid is accumulated. It may be configured to open and drain the liquid.
