In Patent Document 1, the cleaning unit sandwiches a nonwoven fabric arranged on the end side of a plurality of pin members between a plurality of pin members and a member having a plurality of holes corresponding to the pin members, thereby cleaning each of the pin members. The pin member is configured to be covered with a non-woven fabric.

Therefore, at the tip of the pin member covered with the non-woven fabric, in other words, at the tip of the cleaning portion, the non-woven part may be stretched and thinned. Thinning of the nonwoven can result in reduced soil retention and tearing of the nonwoven.

One aspect of the present disclosure provides a technique for suppressing thinning of the nonwoven fabric at the tip of the cleaning part.

One aspect of the present disclosure is an in-vehicle device comprising a case (10), a plurality of terminals (28), and a cleaning section (27). The case has a first surface (2F) and a second surface (2B), and an insertion port for inserting and removing a card (2) provided with a contact portion (21) exposed on the first surface. (11) is provided and configured to accommodate a card inserted through the insertion slot. The terminals are provided inside the case, and are electrically connected to the card by coming into contact with the contact portions when the card is accommodated in the case.
The cleaning part is provided inside the case, and has a plurality of protrusions (271) that come into contact with the contact part in the process of inserting the card through the insertion slot. The cleaning section also includes a plurality of convex members (41), a sheet (42), and a pressing section (43). The convex member is formed in a columnar shape. A sheet is a single sheet that covers a plurality of convex members.
The holding part is formed with one opening (431) through which a plurality of convex members pass, and a holding member ( 24). The pressing portion is configured to hold the edge of the sheet between itself and the holding member. The cleaning portion contacts the contact portion at a convex portion, which is a convex member covered with a sheet.

According to such a configuration, since the plurality of convex members are inserted through one opening, the plurality of convex members are each inserted through a plurality of through-holes provided for each convex member. The sheet is less likely to be stretched at the tip of the convex member. That is, it is possible to prevent the sheet from becoming thin at the leading end of the cleaning unit. Moreover, as a result, it is possible to reduce the amount of dirt that the sheet retains and to prevent the sheet from tearing.

[1-4. Details of the cleaning part]
The cleaning section 27 includes a plurality of convex members 41, one wiping cloth 42, and a pressing section 43 shown in FIGS. 8-10. In this embodiment, the pressing portion 43 is provided on the lens member 25 .

As shown in FIG. 9, the convex member 41 is formed integrally with the key member 24 and has a columnar shape that protrudes downward from the lower surface of the key member 24 . The key member 24 corresponds to a holding member that holds the convex member 41 .

The convex member 41 is formed in a columnar shape with an elliptical cross section, but the present disclosure is not limited to this. The convex member 41 can be formed in various columnar shapes such as a cylindrical columnar shape and a polygonal columnar shape such as a triangular columnar shape and a square columnar shape.

Further, the convex member 41 is formed in a shape having a flat tip portion. In other words, the convex member 41 is formed so that the tip portion thereof is flat.
Also, for convenience, an example in which the number of convex members 41 is three is illustrated, but the present disclosure is not limited to this, and the number of convex members 41 may be two or four or more.

As shown in FIG. 6, each of the convex members 41 is a straight line parallel to the front-rear direction, and any one of the above-described three terminals 28 arranged side by side in the left-right direction. It is provided at a position on the same line as the straight line containing the set.

Further, the lateral width of the convex member 41 is larger than the lateral width 28W of the terminal 28 positioned on the same line as the convex member 41 . That is, as will be described later, the width 27W in the horizontal direction of the contact surface, which is the surface of the convex member 41 that contacts the contact portion 21 via the wiping cloth 42, is larger than the width 28W.

Further, the width of the convex member 41 in the front-rear direction is larger than the width 28W in the left-right direction of the terminal 28 positioned on the same line as the convex member 41 . That is, as shown in FIGS. 6 and 8, the width 27D in the front-rear direction of the contact surface, which is the surface where the convex member 41 contacts the contact portion 21 via the wiping cloth 42, is larger than the width 28W.

In this embodiment, as shown in FIGS. 6 and 8, the plurality of convex members 41 are linearly arranged in the horizontal direction. In other words, the plurality of convex members 41 are arranged side by side in a straight line so as to be parallel to the left-right direction.

The wiping cloth 42 is a piece of cloth-like member that covers each of the plurality of convex members 41 . The wiping cloth 42 is made of a material that can retain dirt and withstand repeated sliding, for example. The material forming the wiping cloth 42 will be described later.

As shown in FIG. 9, the wiping cloth 42 before covering the plurality of linearly arranged convex members 41 has a substantially rectangular shape. The wiping cloth 42 covers the convex members 41 along the shape of the convex members 41 from the tip side of the convex members 41 so as to wrap the respective convex members 41 .

As shown in FIG. 10, the pressing portion 43 is formed with one opening 431 that is large enough for all of the convex members 41 (that is, all three convex members 41) to pass through. As shown in FIG. 10 , the opening 431 is formed in a shape that separates adjacent through spaces 435 in the opening 431 along the shape of the convex member 41 , with the spaces through which the respective convex members 41 pass as through spaces 435 . ing.

In other words, the pressing portion 43 has an opening 432 in which an opening 431 is formed. The through space 435 refers to the space through which the convex member 41 penetrates at the opening 431 . The opening 432 is a portion included in the pressing portion 43 and near the opening 431 .

For example, in FIG. 10 , the dividing portion 433 is shaped like connecting two substantially 1/4 fan-shaped arcs, and is formed in a shape protruding from the opening 432 toward the opening 431 . However, the shape of the dividing portion 433 is not limited to this, and may be any shape that protrudes toward the opening 431 side. The partitioning part 433 may have various shapes such as a triangle, a square, a trapezoid, an arc shape, etc. that protrude toward the opening 431 side, for example.
In addition, in the example of the present disclosure, two partitioning portions 433 are formed for each two adjacent through spaces to partition them. That is, in the present disclosure, four partitions 433 are formed. However, the number of delimiters 433 is not limited to this, and may be plural or singular.

The pressing portion 43 (that is, the lens member 25 provided with the pressing portion 43 ) is attached to the key member 24 holding the convex member 41 so that the convex member 41 covered with the wiping cloth 42 passes through the opening 431 . It is attached. That is, the lens member 25 is configured to hold the end of the wiping cloth 42 between itself and the key member 24 .

Here, assembly of the cleaning unit 27 will be described with reference to FIGS. 11 to 13. FIG. First, as shown in FIG. 11, the key member 24 includes at least one key member sandwiched between the convex members 41a and 41c located at both ends among the root portions of the plurality of convex members 41 (that is, 41a to 41c). A double-sided tape 50 is adhered to the root portion. However, this embodiment is not limited to this. The double-sided tape 50 may be adhered, for example, to the root portions of all the plurality of convex members 41 (eg, 41a-41c) of the key member 24. FIG. A base portion of the convex member 41 corresponds to the key member 24 .

Further, in FIG. 11, the double-sided tape 50 is formed in an annular shape by hollowing out a shape corresponding to the convex member 41, but the present embodiment is not limited to this. The shape of the double-sided tape 50 can be any shape.

Next, as shown in FIG. 12, the wiping cloth 42 is caused to run along each of the plurality of convex members 41 (that is, the wiping cloth 42 is made to conform) to the plurality of convex members 41 . Each member 41 is covered with a wiping cloth 42 . At this time, a portion of the wiping cloth 42 is fixed to the key member 24 by the double-sided tape 50 by pressing the wiping cloth 42 against the double-sided tape 50 .

Next, the lens member 25 is assembled to the key member 24 so that the entire convex member 41 covered with the wiping cloth 42 is passed through the opening 431 .
As a result, as shown in FIG. 13, the end portion of the wiping cloth 42 after the key member 24 and the lens member 25 are assembled is positioned between the key member 24 and the lens member 25 between the key member 24 and the lens member 25 . pressed down by In other words, the ends of the wiping cloth 42 are held between the key member 24 and the lens member 25 .

In addition, since the opening 431 is gently partitioned into each through space 435 through which the convex member 41 passes by the partitioning portion 433 , the wiping cloth 42 is held down by the partitioning portion 433 toward each convex member 41 . Thereby, each convex member 41 is covered with the wiping cloth 42 so that the wiping cloth 42 fits the convex member 41 exactly.

As shown in FIG. 14, the cleaning unit 27 assembled in this manner has a plurality of protrusions 271 formed from the protrusions 41 covered with the wiping cloth 42, and the contact portions 21 and the contact portions 21 at the protrusions 271, respectively. Contact. Since the width 27D of the protrusion 271 in the front-rear direction is larger than the width 28W of the terminal 28 positioned on the same line in the front-rear direction, more dirt can be retained in the front-rear direction than when the width 28W is smaller than the width 28W. can. The width 27D of the convex portion 271 in the front-rear direction is the width in the front-rear direction of the convex member 41 covered with the wiping cloth 42 . The width 27D is smaller than the width 21D of the contact portion 21 in the front-rear direction.

Also, since the wiping cloth 42 is pressed between the key member 24 and the lens member 25 by the pressing portion 43, it is difficult for the wiping cloth 42 to come off from the convex member 41 during wiping. Furthermore, as shown in FIG. 15, the wiping cloth 42 is held down toward the protruding member 41 by the dividing portion 433, so that the wiping cloth 42 is less likely to fall off from the protruding member 41 during wiping.

<Operation by cleaning section>
Next, the operation of the cleaning section 27 will be described. As shown in FIG. 16 , the in-vehicle device 1 further includes a plurality of (for example, two in this embodiment) projections 10C provided inside the case 10 . Each protrusion 10C is provided below the insertion port 11 integrally with the upper case 10A. Specifically, the protrusions 10C are formed as part of the upper case 10A on the left and right sides of the insertion opening 11 and below the insertion opening 11 when viewed from the front of the in-vehicle device 1 . Each of the projections 10C abuts on both ends of the back surface 2B of the card 2 in the horizontal direction during the accommodation process.

The height of each projection 10C is set so that the gap between the projection 10C and the convex member 41 (that is, the projection 271) in the vertical direction of the in-vehicle device 1 is equal to or less than the thickness of the card 2. FIG. As a result, each time the card 2 is inserted or removed from the insertion slot 11, both lateral ends of the back surface 2B of the card 2 are supported by the projections 10C, and the center of the front surface 2F of the card 2 in the lateral direction is supported. The part is pressed against the cleaning part 27 .

That is, in the vicinity of the insertion port 11 , the in-vehicle device 1 gently bends the card 2 into a U-shape when viewed from the front of the in-vehicle device 1 , and cleans the contact portion 21 with the wiping cloth 42 of the cleaning portion 27 . Remove by wiping with

<Material of wiping cloth>
Next, the material of the wiping cloth 42 will be explained. Non-woven fabrics, woven fabrics, knitted fabrics, and felts, for example, can be used as materials for the wiping cloth 42 . Properties of each of these materials are shown in FIG. FIG. 17 also shows the degree of suitability for the wiping cloth 42 for a plurality of items indicating various properties of the material. Suitability for the wiping cloth 42 is indicated by three levels of "⊚", "∘", and "Δ" in descending order of degree. Even materials marked with “Δ” in any of the items can be applied to the wiping cloth 42 .

It is preferable that the material constituting the wiping cloth 42 is less likely to generate fiber waste. This is because if fiber waste is generated from the material forming the wiping cloth 42 and enters the in-vehicle device 1 , it becomes difficult for the circuit assembly 23 to read the information recorded on the card 2 . From this point of view, the nonwoven fabric is suitable for the wiping cloth 42 among the materials shown in FIG.

It is preferable that the material constituting the wiping cloth 42 has a moderately large gap between fibers. This is because dirt is easily retained. From this point of view, among the materials shown in FIG. 17, nonwoven fabric, knitted fabric, and felt are suitable for the wiping cloth 42, and nonwoven fabric and felt are particularly suitable.

It is preferable that the material forming the wiping cloth 42 has high followability to the card 2 . This is because the distance from the card 2 to the contact portion 21 may vary. As a method for improving followability, for example, the wiping cloth 42 may be made of a highly flexible material or a highly flexible material. From this point of view, among the materials shown in FIG. 17, nonwoven fabric, woven fabric, and knitted fabric are suitable for the wiping cloth 42, and nonwoven fabric and felt are particularly suitable.

The material forming the wiping cloth 42 preferably has a high tensile strength. This is because even if the card 2 is repeatedly inserted and removed, it will not easily break. From this point of view, among the materials shown in FIG. 17, nonwoven fabric, woven fabric, and knitted fabric are suitable for the wiping cloth 42, and woven fabric is particularly suitable.

The material forming the wiping cloth 42 preferably has high productivity. This is because it is advantageous for mass production of the in-vehicle device 1 . From this point of view, among the materials shown in FIG. 17, nonwoven fabric and felt are suitable for the wiping cloth 42, and nonwoven fabric is particularly suitable.

It is desirable that the material constituting the wiping cloth 42 has many variations in material density, thickness, and the like. It is preferable that the frictional force generated between the wiping cloth 42 and the card 2 is small, because it is easy to adjust the frictional force generated between the wiping cloth 42 and the card 2 by adjusting the density and thickness of the material. be. From this point of view, among the materials shown in FIG. 17, nonwoven fabric and felt are suitable for the wiping cloth 42, and nonwoven fabric is particularly suitable.

Considering the various viewpoints described above, the non-woven fabric is most suitable for the wiping cloth 42 among the materials shown in FIG. 17 .
Nonwoven fabrics have slightly different properties depending on the manufacturing method. FIG. 18 shows an example of a nonwoven fabric manufacturing method. FIG. 11 shows the degree of suitability for the wiping cloth 42 with respect to the properties of each nonwoven fabric produced by different manufacturing methods. 11 have the same meanings as the same symbols in FIG. However, these symbols in FIG. 18 are representations based on comparison between the nonwoven fabrics shown in FIG. 18, and do not necessarily have the same absolute meaning as the same symbols in FIG. Each of the nonwoven fabrics shown in FIG. 18 is suitable for the wiping cloth 42 .

As shown in FIG. 18, the nonwoven fabrics produced by different manufacturing methods differ in the length of the fibers that make up the nonwoven fabric, the followability (i.e., softness) of the nonwoven fabric to the card 2, the strength of fiber restraint, and the heat resistance. There is

The material forming the wiping cloth 42 is preferably long fibers. This is because the long fibers are less likely to fray than the short fibers when sliding against the card 2 . From this point of view, of the manufacturing methods shown in FIG. 18, the nonwoven fabrics manufactured by the spunbond method and the chemical bond method are suitable for the wiping cloth 42, and the nonwoven fabrics manufactured by the spunbond method are particularly suitable.

It is preferable that the material forming the wiping cloth 42 has high adaptability to the card 2 (that is, is soft). From this point of view, among the manufacturing methods shown in FIG. 18, a nonwoven fabric manufactured by a manufacturing method other than the chemical bonding method is particularly suitable for the wiping cloth 42 .

It is preferable that the material forming the wiping cloth 42 has a strong constraint. This is because there is a concern that the fibers may become frayed due to pulling when covering the convex member 41 . From this point of view, among the manufacturing methods shown in FIG. 18, nonwoven fabrics manufactured by the spunbond method, the chemical bond method, and the thermal bond method are suitable for the wiping cloth 42, and the nonwoven fabrics manufactured by the chemical bond method and the thermal bond method are suitable. is particularly preferred.

The material forming the wiping cloth 42 preferably has excellent heat resistance. This is because the inside of the vehicle in which the in-vehicle device 1 is installed may become hot, for example, in the summer. From this point of view, among the manufacturing methods shown in FIG. 18, nonwoven fabrics manufactured by the spunbond method, the chemical bond method, and the needle punch method are particularly suitable for the wiping cloth 42, except for other dry methods whose properties are unconfirmed. .

Considering the various points of view described above, the nonwoven fabric manufactured by the spunbond method is most suitable for the wiping cloth 42 among the nonwoven fabrics manufactured by the manufacturing method shown in FIG.
The wiping cloth 42 in this embodiment is composed of a nonwoven fabric manufactured by a spunbond method.

The pressing portion 43 is formed with one opening 431 through which the plurality of convex members 41 pass. It is attached to a key member 24 which is a holding member for holding. The holding portion 43 is configured to hold the end portion of the wiping cloth 42 between itself and the holding member.

The holding member is a member that holds the convex member 41, and the key member 24 corresponds to the holding member. The cleaning portion 27 contacts the contact portion 21 at a plurality of convex portions 271 using the convex member 41 covered with the wiping cloth 42 as the convex portions 271 .

According to such a configuration, since the plurality of convex members 41 are inserted through one opening 431, it is easier than the case where each of the plurality of convex members 41 is inserted through a through hole provided for each convex member 41. Also, the wiping cloth 42 is less likely to be stretched at the tip of the convex member 41 . In other words, thinning of the wiping cloth 42 at the tip of the cleaning portion 27 can be suppressed. Moreover, as a result, it is possible to reduce the amount of dirt that the wiping cloth 42 holds and to prevent the wiping cloth 42 from tearing.

(2b) The plurality of convex members 41 are arranged linearly. Specifically, the card 2 is formed in a rectangular shape having short sides and long sides, and the plurality of convex members 41 are arranged linearly in the short side direction of the card 2 . This allows the shape of the wiping cloth 42 to be simpler than when the convex members 41 are not arranged linearly.

(2c) The wiping cloth 42 is formed in a rectangular shape. This makes it suitable for mass production.
(2d) The holding portion 43 has an opening 432 in which an opening 431 is formed. Opening 432 includes at least one delimiter 433 . The partitioning portion 433 is a portion included in the holding portion 43, and the partitioning portion 433 partitions the adjacent through-spaces 435 in the opening 431, with the through-spaces 435 defined as the spaces through which the respective convex members 41 penetrate in the opening 431. It is a part.

As a result, the wiping cloth 42 can be pressed toward the convex member 41 by the separating portion 433 . In other words, the wiping cloth 42 sandwiched between the key member 24 and the lens member 25 can be made more difficult to fall off from the convex member 41 than when the dividing portion 433 is not provided.

(2e) The cleaning portion 27 includes a double-faced tape 50 adhesion portion for adhering the wiping cloth 42 to at least one of the base portions of the plurality of convex members 41 sandwiched between the convex members 41 at both ends. Prepare. As a result, the wiping cloth 42 is fixed to the root portion (that is, the key member 24 ) of the convex member 41 by the double-faced tape 50 , so that the wiping cloth 42 can be prevented from falling off from the convex member 41 .

(2f) The wiping cloth 42 is made of non-woven fabric. As a result, fiber waste is less likely to occur, and the occurrence of readout failures of information recorded on the card 2 can be suppressed. In addition, it is easy to retain dirt during wiping, and the followability of the wiping cloth 42 to the card 2 can be enhanced. In addition, deterioration (for example, tearing) of the wiping cloth 42 due to repeated insertion and removal of the card 2 can be suppressed, which is advantageous for mass production. Also, the frictional force generated between the wiping cloth 42 and the card 2 can be reduced.

(2g) The wiping cloth 42 is composed of a nonwoven fabric manufactured by a spunbond method. As a result, the wiping cloth 42 is less likely to become frayed, so fiber waste is less likely to occur, and the occurrence of readout failures of information recorded on the card 2 can be further suppressed. Also, the followability of the wiping cloth 42 to the card 2 can be further enhanced. In addition, since the restraint is strong, it is possible to suppress fraying of the fibers due to pulling when the convex member 41 is covered. Moreover, deterioration of the wiping cloth 42 due to heat can be suppressed.

In this embodiment, the front surface 2F corresponds to the first surface, and the back surface 2B corresponds to the second surface. The wiping cloth 42 corresponds to the sheet, the key member 24 corresponds to the holding portion, and the double-sided tape 50 corresponds to the adhesion portion.
