  DESCRIPTION OF EMBODIMENTS Hereinafter, an in-vehicle communication device according to the present invention will be described in detail with reference to the accompanying drawings by exemplifying a preferred embodiment by exemplifying a mounting structure of the in-vehicle communication device to a motorcycle.

  FIG. 1 is a partially omitted schematic perspective view in which a front portion of a vehicle body of a motorcycle 12a to which an ETC in-vehicle device 10a as an in-vehicle communication device according to a first embodiment of the present invention is applied is enlarged. FIG. 2 is a partially omitted schematic side view of the motorcycle 12a shown in FIG. 1, and FIG. 3 is a partially omitted schematic front view of the motorcycle 12a shown in FIG.

  In the first embodiment, an in-vehicle communication device according to the present invention will be described by exemplifying a motorcycle 12a which is a so-called naked type straddle-type vehicle. In the motorcycle 12a, regarding the mechanisms and components provided symmetrically one by one on the left and right of the vehicle body, "L" is attached to the reference symbol on the left and "R" is attached to the reference symbol on the right. Shall. Further, in order to facilitate understanding, in each drawing, “L” is attached to the arrow indicating the left side of the vehicle body and “R” is attached to the arrow indicating the right side of the vehicle body according to the direction viewed from the seated driver. An arrow indicating the front side of the vehicle is described with “Fr”, an arrow indicating the rear side of the vehicle body with “Rr”, and so on.

  As shown in FIGS. 1 to 3, a pair of front forks 16 </ b> L and 16 </ b> R is supported on the motorcycle 12 a via a head pipe 14 that is pivotally supported in front of a vehicle body frame 13 that constitutes the vehicle body. A front wheel 18 that is a steered wheel is supported on the lower end side of 16L and 16R. That is, the front forks 16L and 16R are connected at the position corresponding to the upper end side of the head pipe 14 by the top bridge 20 and at the position corresponding to the lower end side of the head pipe 14 by the under bridge 22. Thus, the left and right front forks 16L and 16R are pivotally supported by the head pipe 14 integrally.

  The handle 24 that steers the front wheel 18 is fixed to the upper surface side of the top bridge 20 so that the front wheel 18 can be steered via the front forks 16L and 16R. The handle 24 is used for operating a headlight 26 disposed in front of the head pipe 14 via stays 25L and 25R, and blinkers 28L and 28R disposed below the headlight 26. Switch units 30L and 30R are provided. The stays 25L and 25R are fixed to the front forks 16L and 16R. A meter set 31 in which various meters are arranged is disposed above the headlight 26, and side mirrors 32L and 32R are attached to the inside of the grips on both ends of the handle 24, respectively. Reference numeral 33 in FIG. 1 indicates a fuel tank, and it goes without saying that an engine, a seat, a rear wheel, etc. (not shown) are provided from the lower side to the rear side of the fuel tank 33 in the motorcycle 12a. Yes.

  Such a motorcycle 12a is equipped with the ETC vehicle-mounted device 10a as the vehicle-mounted communication device according to the first embodiment, whereby an external communication station, for example, a fee is charged via the ETC vehicle-mounted device 10a. It is possible to automatically communicate with the transmitting / receiving device 38 of the ETC gate 36 provided at the toll gate on the road (see FIG. 1).

  Then, next, the ETC onboard equipment 10a which concerns on the 1st embodiment, and its attachment structure are demonstrated. In FIG. 5 and the like, the motorcycle 12a is not illustrated, but an arrow L or the like indicating the left side of the vehicle body indicates a direction in a state where the ETC on-vehicle device 10a is attached to the motorcycle 12a. The same shall apply.

  The ETC in-vehicle device 10a transmits / receives an ETC gate 36 to / from a main body unit 42 that is a card reader unit in which an authentication memory card (ETC card, memory card) 40 (hereinafter also referred to as a card 40) in which various information is recorded. It comprises an antenna 44 that transmits and receives information to and from the device 38, and an indicator unit 46 that displays the operating state of the ETC on-vehicle device 10a by lighting the lamp. The main body portion 42, the antenna 44 and the indicator portion 46 are electrically connected via signal cables 48 and 50, respectively, and the main body portion 42 is mounted on the motorcycle 12a via a power cable 52 (not shown). It is electrically connected to the battery. In this case, for example, the card 40 can read out various information of the recorded user and the like, while writing the toll gate passage information received from the transmitting / receiving device 38 of the ETC gate 36 via the ETC on-board device 10a. It consists of a so-called IC card on which a possible IC chip is mounted. The indicator unit 46 notifies the driver of the operating state of the ETC on-vehicle device 10a, for example, by turning on, turning off, and blinking the red LED lamp and the green LED lamp (see FIG. 33).

  As can be understood from FIGS. 1 to 3, in the ETC in-vehicle device 10 a according to the first embodiment, the main body 42 is outside the front fork 16 </ b> R (outside in the vehicle width direction) and below the handle 24. At a certain position, more specifically, at a position between the top bridge 20 (handle 24) and the underbridge 22 in the vertical direction of the vehicle body, via an attachment mechanism 54 fixed to the vehicle body along the front fork 16R. is set up. In this case, at least a part of the main body 42 (attachment mechanism 54) is set at a position included in the rotation locus range of the handle 24 in a plan view shown in FIG. That is, the main body 42 (attachment mechanism 54) is installed within a range that can easily be reached by the driver's hand seated on the seat.

  Further, since the main body portion 42 (attachment mechanism 54) is fixed to the vehicle body along the front fork 16R between the top bridge 20 and the underbridge 22, the irradiation direction of the blinker 28R and the main body portion 42 are It does not cross | intersect by the side view shown in FIG. 2, and this effectively prevents that the visual recognition from the outside of the blinker 28R is obstructed by the main body part 42.

  The signal cables 48 and 50 and the power cable 52 all extend downward from the lower surface side of the attachment mechanism 54 and then are routed to a predetermined location (see FIG. 2). In this case, the signal cable 48 that connects the main body 42 and the antenna 44 is usually configured with a sufficient length to reach from the front of the vehicle body to the rear of the vehicle body in order to ensure the degree of freedom of installation of the ETC on-vehicle device 10a. On the other hand, it is difficult to give excessive bending or the like from the viewpoint of ensuring the stability of communication. Therefore, as shown in FIG. 3, in the case of the first embodiment, the signal cable 48 is drawn downward from the main body portion 42, and is routed from the lower side of the headlight 26 to the upper side through the opposite side (the left side of the vehicle body). Then, in a state in which it is circulated with a predetermined diameter that does not cause bending, it is housed and fixed in a gap 55 formed between the headlight 26 and the meter set 31 together with a connector (not shown) provided in the middle, The signal cable 48 is protected and the appearance is improved.

  The antenna 44 is installed at a substantially central portion (between two meters) at the upper part of the outer surface of the meter set 31 in order to ensure the stability of communication with the transmitting / receiving device 38 of the ETC gate 36. On the other hand, in order to ensure visibility from the driver, the indicator unit 46 is installed between the handle 24 and the meter set 31 and near the one end side (right side in the vehicle width direction) of the meter set 31. ing.

  FIG. 5 is an exploded perspective view showing the main body 42 and the attachment mechanism 54 of the ETC on-vehicle device 10a according to the present embodiment.

  The attachment mechanism 54 includes a base bracket 56 that is fixed to the vehicle body and a cover member 58 that is detachably attached to the base bracket 56, and a main body 42 that constitutes the ETC on-vehicle device 10 a is formed on the surface of the base bracket 56. By fixing, the main body 42 can be accommodated between the base bracket 56 and the cover member 58.

  The base bracket 56 is a substantially rectangular flat plate bracket made of, for example, aluminum, and a bolt 64 is inserted into two mounting holes 62 formed in the mounting portion 60 protruding to the rear side of the vehicle body. It is fastened together with the headlight 26 fixing stay 25R fixed to the front fork 16R, and is attached to the vehicle body with its thin plate thickness direction along the vehicle body width direction. A hook 68 that engages with the engagement hole 66 of the cover member 58 is provided on the upper edge of the base bracket 56 that is orthogonal to the mounting portion 60 side. The hook 68 is a hook portion that protrudes upward after bending in the vehicle body outer direction (right side in the vehicle width direction).

  Further, at the edge of the base bracket 56 on the front side of the vehicle body, a rib 70 having a substantially triangular shape is provided at an upper portion thereof, protruding in the vehicle body inner direction (left side in the vehicle width direction) in front view (FIGS. 3 and FIG. 3). 5). The rib 70 has a shape corresponding to the curved surface shape of the lens of the headlight 26 in the front view shown in FIG. 3, thereby effectively closing the gap between the base bracket 56 and the outer surface of the headlight 26. It is possible to reduce the amount of air flowing through the gap during traveling, thereby improving wind and sound insulation.

  The cover member 58 is made of, for example, a resin material, and has a box shape in which one surface on the base bracket 56 side is opened and a central portion is slightly bulged, and the upper surface thereof is engaged with the hook 68. A detachable portion 78 having a hole 66 is formed to bulge, while a hook member 77 protruding toward the base bracket 56 is provided on the lower surface side. Such a cover member 58 is fixed to the base bracket 56 by engaging the hook member 77 with the lower end edge of the base bracket 56 and engaging the engaging hole 66 with the hook 68. Further, the cover member 58 is formed with a bolt cover portion 80 that covers the mounting portion 60 and hides it from the outside in a state where the cover member 58 is fixed to the base bracket 56 (see FIG. 5 and FIG. 6A).

  Therefore, in such an attachment mechanism 54, the main body portion 42 is fixed to the surface of the base bracket 56 fixed to the vehicle body by the attachment portion 60 by, for example, an elastic double-sided tape 85 (see FIG. 5) or a bolt (not shown). In this state, the cover member 58 can be attached to and detached from the base bracket 56. In this case, as understood from FIGS. 2 and 5, the opening / closing direction of the lid 90 of the main body 42 and the mounting direction of the cover member 58 with respect to the base bracket 56 are set to be different from each other by approximately 90 °.

  FIG. 7 is a schematic perspective view of the main body 42 constituting the ETC on-vehicle device 10a, and FIG. 8 is a schematic plan view of the main body 42 shown in FIG. 7 with the lid 90 opened. The main body 42 constituting the ETC on-vehicle device 10a includes a case 88 having a bottomed inner surface shape that can hold the card 40 in a waterproof state, and a lid 90 that opens and closes the case 88. . That is, the case 88 and the lid 90 can be opened and closed by a hinge 92, and can be held in close contact by a buckle (holding body, lid) 94 provided on the surface opposite to the hinge 92. A waterproof seal member 95 is interposed between the case 88 and the lid 90.

  The case 88 includes an electronic circuit 91 provided with a connector (spring contact) 89 that can be electrically connected to an IC chip (not shown) provided on the card 40. The connector 89 includes a case 88 and a lid. It faces a card holding part (card holding space) 88a sandwiched between the body 90 (FIG. 8). The inside of the case 88 of the connector 89 has a waterproof structure, which reliably prevents rainwater or the like that has entered the card holding portion 88a from entering the case 88 when the card 40 is attached / detached in the rain.

  The buckle 94 is provided so as to be openable and closable with respect to the case 88 via a hinge 93, and the claw portion 94 a engages with the protrusion 90 a on the lid body 90 side, thereby closing the lid body 90 with respect to the case 88. (See FIGS. 8 and 9). As shown in FIG. 9, the hinge 93 includes a roll-shaped receiving portion 93 a that is provided on the case 88 side and is partially opened, and a pin portion 93 b that is provided on the buckle 94 side and corresponds to the receiving portion 93 a. Then, the pin portion 93b is press-fitted into the opening of the receiving portion 93a, so that the buckle 94 is supported so as to be openable and detachable.

  In the main body portion 42 constituting such an ETC on-vehicle device 10a, a lock that locks the lid 90 in the closed state is provided together with a buckle 94 that functions as a holding body (holding mechanism) that holds and fixes the lid 90 in the closed state. A mechanism 130 is provided.

  As shown in FIGS. 7 to 9, the lock mechanism 130 includes a nut (insert nut) 132 embedded in a surface facing the buckle 94 of the case 88, and a lock that is provided on the buckle 94 and can be screwed into the nut 132. Bolts 134 are provided on the surface opposite to the hinge 92 that connects the case 88 and the lid 90. Accordingly, the lid 90 is closed with respect to the case 88, and the lock bolt 134 is fastened to the nut 132 in a state where the buckle 94 is in the closed position. The opening and closing of is also locked.

  FIG. 10A is a partially omitted schematic cross-sectional view taken along line XX in FIG. 7 and is an enlarged cross-sectional view of the main part of the lock mechanism 130. FIG. 10B shows the buckle 94 from the state shown in FIG. FIG.

  As shown in FIG. 10A, in the lock mechanism 130, the nut 132 is in a stepped hole 136 formed on the wall surface on the buckle 94 side that divides the space in which the electronic circuit 91 and the like housed in the case 88 are disposed. The inside of the case 88 that is the rear end side is sealed with a seal cap 138. Accordingly, it is possible to effectively avoid the rainwater and the like from entering the case 88 from the hole 136 and the hole of the nut 132 and the electronic circuit 91 and other electronic components from being broken. In this case, unlike the lock bolt 134, the nut 132 is not required to move when the lock mechanism 130 is used. Therefore, by providing the nut 132 on the case 88 side, the waterproof structure can be extremely easily performed. Can do.

  As can be seen from FIG. 8, in the holding space (card holding portion 88a) of the card 40 of the case 88, the connector 89 is arranged offset to one end side (the upper end side in FIG. 8) in plan view, and the nut 132 is The other end side opposite to the connector 89 is offset. In the case 88, the electronic components such as the electronic circuit 91 are relatively concentrated in the vicinity of the connector 89, whereas there are relatively few electronic components on the other end side. This is because it is easy to secure the installation space.

  On the other hand, the lock bolt 134 is supported by being inserted into the hole 140 a of the cylindrical wall 140 protruding from the outer surface at a position corresponding to the nut 132 in the buckle 94. A flange 142 having a hole 142a having a diameter smaller than that of the hole 140a is provided at the back (bottom) of the hole 140a. Therefore, in the lock bolt 134, the head portion 134a is arranged outside the flange 142, the screw portion 134b at the tip is arranged inside (case 88 side), and the retaining ring 144 is interposed on the head portion 134a side of the screw portion 134b. As a result, the buckle 94 is held in a rotatable state.

  Between the head 134a of the lock bolt 134 and the flange 142, a spring 146 that urges the lock bolt 134 in the outward direction (head 134a side) is disposed. Accordingly, when the lock bolt 134 is not fastened to the nut 132, the lock bolt 134 is moved away from the nut 132 side by the biasing force of the spring 146 (see FIG. 10B). It can prevent that a front-end | tip (screw part 134b side) protrudes largely from the back side of the buckle 94. FIG. For this reason, as shown in FIG. 10B, when the buckle 94 is opened and closed, the tip of the lock bolt 134 can be prevented from coming into contact with the edge of the hole 136, and the lock bolt 134 is reliably positioned with respect to the nut 132. However, the buckle 94 can be easily set to the closed position. Further, the lock bolt 134 is elastically supported so as to be able to swing with a certain degree of freedom inside the hole portion 142a and the hole portion 140a under the urging action of the spring 146 and to be swingable. Therefore, the positioning of the lock bolt 134 when closing the buckle 94 is further facilitated, and the occurrence of abnormal noise due to the rattling of the lock bolt 134 can be effectively prevented.

  In this case, the amount of engagement between the threaded portion 134b of the lock bolt 134 and the nut 132 is set to be smaller than the stroke amount of the spring 146 (the movement width of the lock bolt 134). Accordingly, the amount of screwing of the lock bolt 134 is prevented from being limited by the spring 146, and the lock bolt 134 can be securely tightened to the nut 132.

  Such a lock bolt 134 is configured to be rotatable only by a release key 148 having a predetermined special key shape (see FIG. 7), and engages a tool provided on the top surface of the head 134a. Therefore, the operation groove 134c has a special shape corresponding to the release key 148. As shown in FIG. 11, the key shape formed in the release key 148 and the corresponding operation groove 134c is a special shape that does not correspond to a general-purpose tool (driver, wrench, etc.). More than 20 types are prepared for the vessel 10a. For this reason, it is possible to effectively prevent users having the same key shape from releasing another person's lock bolt 134 by mistake or intentionally in a normal use state, thereby improving the anti-theft performance of the card 40. be able to.

  As shown in FIG. 7, the release key 148 is configured such that an operation portion 148b formed with a protrusion 148a that engages with an operation groove portion 134c of the lock bolt 134 is rotatably connected to the base end portion 148c. Has been. Accordingly, the base end portion 148c of the release key 148 is integrated with the ignition key of the motorcycle 12a or is connected and held by the ignition key and a coupler, thereby preventing the release key 148 from being lost. Since the lock bolt 134 can be easily operated by rotating the operation unit 148b, the handleability of the lock mechanism 130 can be greatly improved.

  By the way, in the lock bolt 134 having such a special key shape, there is a concern that the head 134a is directly held by a tool such as a pliers and is forcibly rotated to unlock the lock mechanism 130 illegally. . Therefore, in the lock mechanism 130, as shown in FIGS. 7 and 10A and the like, the wall 140 surrounds the periphery of the head 134a of the lock bolt 134, and the height (projection length) h of the wall 140 is sufficiently large. Is set high. That is, even when the lock bolt 134 is urged by the spring 146 and closes to the outermost side (rear side of the vehicle body) (see FIG. 10B), the upper end surface of the wall 140 is higher than the top surface of the head 134a. It is set to be. As a result, the side surface of the head 134a is prevented from being directly gripped by a tool such as a pliers, and unauthorized release of the lock mechanism 130 is made more difficult.

  Furthermore, as shown in FIG. 11, the gap G between the head 134a of the lock bolt 134 and the inner wall surface of the wall 140 is set to be sufficiently small (almost) so that other tools cannot be inserted. . The gap G changes, for example, between a position (circle C1) closest to the center point O of the head 134a and a position farthest (circle C2) in the operation groove 134c provided in the head 134a. The width is set smaller than the width (the distance obtained by subtracting the radius of the circle C1 from the radius of the circle C2) and is set smaller than the groove width of the operation groove 134c. The operation groove 134c is a curved meandering circle surrounding the center point O of the head 134a, and the groove width is the amount of change relative to the center point O of the center line C3 of the operation groove 134c (of the center line C3). It is set smaller than the distance obtained by subtracting the minimum diameter from the maximum diameter. Further, as understood from FIGS. 10A to 11, the head 134 a of the lock bolt 134 is formed with a curved surface whose outer peripheral surface (side surface) is reduced in diameter toward the top, and the shape is substantially in plan view. It is considered a perfect circle. Thus, the head portion 134a is more reliably prevented from being gripped by the tool such as the pliers in the wall portion 140.

  Further, in the lock mechanism 130, the strength of the flange 142 is set to be weaker than the strength of other portions of the buckle 94 and easily broken. Therefore, even if a large force is applied to the wall 140 or the buckle 94 itself by a tool such as a pliers and the buckle 94 is strongly pulled in the opening direction, the threaded portion 134b of the lock bolt 134 is applied to the nut 132. In the fastened state, the flange 142 is first broken while the lock bolt 134 is fastened to the nut 132. That is, the buckle 94 is opened while the lock bolt 134 is left on the case 88 side. Therefore, in the lock mechanism 130, the wall 140, the spring 146, the lock bolt 134, and the retaining ring 144, which are components on the buckle 94 side, are formed as an integral unit with the buckle 94. For this reason, even if the flange 142 is broken as described above, the case 88 and the lid 90 are not damaged, and the repair is only required by replacing the buckle 94.

  Furthermore, since the buckle 94 is attached to the case 88 by a detachable hinge 93, repair and replacement are extremely easy. However, even if the flange 142 is broken in this way, the lock mechanism 130 cannot be used, but the case 88 of the main body 42 and the lid 90 can be held in close contact with each other using the buckle 94. Therefore, the driver can travel to a repair shop, a tool store, or the like with the lid 90 securely closed. As for the hinge 93, as in the case of the flange 142, the pin portion 93b on the buckle 94 side can be more easily broken than the receiving portion 93a on the case 88 side. Then, since the pin portion 93b is broken earlier than the receiving portion 93a, the case 88 can be more reliably avoided from being damaged. Furthermore, as shown by a broken line in FIG. 10B, the wall 140 is formed as a cylindrical part separate from the buckle 94 and is configured to be press-fitted into a hole provided in the wall of the buckle 94. You can also. In this case, when the flange 142 is damaged, only the wall portion 140 and the lock bolt 134 that are units supporting the lock bolt 134 or the like need to be replaced, and the buckle 94 need not be replaced.

  10A, when the lock bolt 134 is fastened to the nut 132, the position of the top surface of the head 134a of the lock bolt 134 is lower (back) than the upper end surface (tip surface) of the wall 140. It is preferable that the height of the wall 140 is not more than half of the height h. Then, it is possible to more reliably prevent the lock bolt 134 from being illegally operated using a tool other than the release key 148 from the outside.

  As shown in FIGS. 2 and 5, the attachment mechanism 54 for fixing the main body 42 of the ETC on-vehicle device 10a having the buckle 94 (holding body) configured as described above and the lock mechanism 130 to the motorcycle 12a, The bottom portion of the base bracket 56 faces the vehicle body side, and its longitudinal direction (direction from the hook 68 side to the hook member 77 side) is fixed in a direction along the front fork 16R. Further, as understood from FIGS. 5 and 12B, the head 134a of the lock bolt 134 constituting the lock mechanism 130 is installed in a state facing the driver side (side seen from the driver) seated on the seat. The

  Further, as shown in FIG. 6B, an elastic member 96 made of sponge, rubber or the like is attached to the inside of the cover member 58 constituting the attachment mechanism 54. As a result, when the cover member 58 is attached to the base bracket 56, the lid 90 of the main body 42 is pressed in the closing direction by the elastic member 96, so that erroneous opening of the lid 90 within the attachment mechanism 54 is ensured. Can be prevented.

  As described above, according to the first embodiment, the main body portion 42 (attachment mechanism 54) constituting the ETC on-vehicle device 10a is outside the front fork 16R (naturally, it may be outside the front fork 16R). In addition, it is fixed to the vehicle body at a position below the handle 24 (between the handle 24 and the underbridge 22) (see FIGS. 2 and 3), and at least a part of the main body portion 42 is seen in plan view in the handle 24. (See FIG. 4). The head 134a of the lock bolt 134 constituting the lock mechanism 130 is installed in a state facing the driver side seated on the seat.

  Therefore, for example, when passing through the ETC gate 36, even if a communication error occurs between the transmission / reception device 38 of the ETC gate 36 and the ETC on-board device 10a of the motorcycle 12a, The cover member 58 of the attachment mechanism 54 can be easily opened while sitting on the seat, the lock mechanism 130 is released, the lid 90 is opened, and the card 40 can be removed from the main body 42. That is, in the first embodiment, the position where the attachment mechanism 54 (main body portion 42) is installed is set within a range where the driver's hand seated on the seat can easily reach, and the lock bolt 134 is attached to the driver. Therefore, the ease of handling of the main body 42 can be greatly improved.

  In this case, the main body 42 constituting the ETC vehicle-mounted device 10a includes a buckle 94 that is a holding body that holds the lid 90 in the closed position, and a lock mechanism 130 that locks the lid 90 in the closed position. Theft prevention is ensured. For this reason, it is possible to install the main body 42 in a state exposed to the outside of the motorcycle 12a, and it is also possible to install the main body 42 directly on the vehicle body via the base bracket 56 without providing the cover member 58. Of course it is possible. Therefore, in the ETC vehicle-mounted device 10a, it is possible to improve the ease of attachment to the vehicle body and the ease of handling. Needless to say, by providing the cover member 58, the waterproof performance and dustproof performance of the main body 42 can be improved.

  Since the mounting mechanism 54 is fixed so that the bottom of the base bracket 56 faces the vehicle body and the longitudinal direction thereof is along the front fork 16R, the flat and thin thickness direction of the mounting mechanism 54 is the vehicle width of the motorcycle 12a. The attachment mechanism 54, that is, the main body 42 hardly protrudes in the vehicle width direction. For this reason, the attachment mechanism 54 (main body portion 42) does not stand out on the appearance of the motorcycle 12a and does not impair the appearance, but the attachment mechanism 54 (main body portion 42) is completely invisible from the outside. Therefore, the driver can appeal that the ETC vehicle-mounted device 10a is mounted on the surroundings.

  In this case, as shown by a broken line in FIG. 7, for example, if a window 90 b that allows the card holding portion 88 a to be visually recognized from the outside is provided on the upper surface of the lid 90, whether or not the card 40 is mounted on the main body 42. This makes it possible to visually recognize these from the outside, and the driver can more reliably avoid forgetting to insert the card 40. Further, when the motorcycle 12a is stopped, etc., it is possible to notify the surroundings that the card 40 is not in the main body portion 42, so that unauthorized destruction of the main body portion 42 for the purpose of theft of the card 40 can be prevented. The effect that it can prevent is also acquired.

  Further, since the main body 42 is fixed to the front fork 16R, the space around the handle 24 is not blocked, and another electronic device such as a navigation system or an audio speaker can be mounted in the space. it can. On the other hand, since the antenna 44 that is sufficiently smaller than the main body 42 is provided on the upper part of the meter set 31, it is possible to ensure the stability of communication. Similarly, since the indicator part 46 that is sufficiently smaller than the main body part 42 is provided in the space between the meter set 31 and the handle 24, it is possible to ensure visibility from the driver, and The space around the handle 24 is not blocked.

  In this case, since the main body part 42, the antenna 44, and the indicator part 46 of the ETC on-board device 10a all rotate together with the handle 24, the signal cables 48 and 50 are bent and damaged by the steering of the handle 24 and the like, resulting in poor communication. Etc. can be effectively avoided.

  Further, since the antenna 44 is installed at a position above and in front of the top bridge 20 and the handle 24, an obstacle between the antenna 44 and the transmission / reception device 38 of the ETC gate 36 is provided. And the stability of communication can be ensured more reliably.

  In addition, since the ETC vehicle-mounted device 10a includes the lock mechanism 130 that locks the lid 90 in the closed position, the main body 42 can be attached to a relatively free position on the appearance of the motorcycle 12a. As shown in FIG. 13, the space between the fixing members 24 a and 24 b for fixing the handle 24 can be fixed via a bracket (not shown) that is fixed around the handle 24. Thereby, the handleability of the ETC onboard equipment 10a can be further improved.

  In addition to the case 88, the position of the lock bolt 134 (nut 132) constituting the lock mechanism 130 of the ETC on-vehicle device 10a is, for example, a position corresponding to the lid 90 side as shown in FIG. As shown to 14B, it is also possible to arrange | position in the position corresponding to the upper surface side of the cover body 90. FIG. Furthermore, as shown in FIG. 14C, the lock bolt 134 can be disposed directly on the lid 90 instead of the buckle 94.

  As a holding body for holding the lid 90 of the ETC in-vehicle device 10a in the closed position, in addition to the above-described buckle 94, as shown in FIG. 15, a clip-type buckle 150 formed in a substantially U-shape, a slide type Or a buckle (not shown).

  Also, the release key 148 for releasing the lock mechanism 130 and the lock bolt 134 having the operation groove 134c corresponding to the release key 148 can be changed to, for example, the release key 152 and the lock bolt 154 shown in FIGS. .

  16 is a schematic exploded perspective view showing the release key 152 and the lock bolt 154 corresponding to the release key 152, and FIG. 17 is a schematic perspective view in a state where the release key 152 and the lock bolt 154 shown in FIG. 16 are assembled. . The release key 152 includes a protrusion 152a that engages with the lock bolt 154, an operation part 152b that is fixed to the distal end of the protrusion 152a, and a base end part 152c that rotatably supports the operation part 152b (protrusion 152a). It consists of and. The base end portion 152c is, for example, a portion that is configured integrally with the ignition key of the motorcycle 12a or connected via a coupler, and the operation portion 152b is locked by the driver rotating the protruding portion 152a. This is a part for releasing the mechanism 130.

  In this case, the projecting portion 152a includes a first cam 158 that sequentially meshes with a knurled 156 projecting from the distal end surface of the operation portion 152b, and a second cam 160 having a smaller diameter than the first cam 158. That is, the first cam 158 and the second cam 160 are formed at the respective central portions, and can be meshed with the knurl 156 at a desired angle by the knurl holes 158a and 160a that mesh with the knurl 156. 158 and the second cam 160 are fixed by a bolt 162 that is screwed into an internal thread portion provided in the knurled 156. The first cam 158 and the second cam 160 are each provided with a convex portion 158b and a convex portion 160b that protrude outward.

  Therefore, by setting the convex portions 158b and the convex portions 160b of the first cam 158 and the second cam 160 to desired positions under the meshing action with the knurl 156, the protruding portion 152a can be formed from various types of shapes. Functions as a key.

  On the other hand, the lock bolt 154 has a head portion 154a formed in a bottomed cylindrical shape, and a knurled surface 164 formed on the inner peripheral surface thereof. Knurled surfaces 166a and 168a that can be engaged with the knurled pin 164 are formed on the outer peripheral surface. The provided first cam receiving ring 166 and second cam receiving ring 168 are accommodated. That is, the first cam receiving ring 166 is provided with a hole 166c formed with a recess 166b into which the first cam 158 including the protruding portion 158b can be inserted, and the second cam receiving ring 168 has the protruding portion 160b. A hole 168c in which a recess 168b into which the second cam 160 including the same can be inserted is formed.

  The head portion 154a in which the first cam receiving ring 166 and the second cam receiving ring 168 are accommodated has a screw portion 170 formed on the outer peripheral surface thereof, and the screw portion 172 on the inner peripheral surface with respect to the screw portion 170. When the cover member 174 formed with is screwed, the first cam receiving ring 166 and the second cam receiving ring 168 are retained and prevented from coming off. Reference numeral 176 denotes a cap that closes the opening 174a of the cover member 174 when the lock bolt 154 is not operated.

  Accordingly, similarly to the release key 152, the recesses 166b and the recesses 168b of the first cam receiving ring 166 and the second cam receiving ring 168 are set to desired positions with respect to the lock bolt 154 as well as the release key 152. Accordingly, the key shape of the protrusion 152a of the release key 152 can be accommodated.

  As described above, according to the release key 152 and the lock bolt 154, the key shape can be set to various types compared to the release key 148 and the lock bolt 134 described above, but basically the same parts are used. The driver (user) can change the setting to a desired key shape as necessary. For this reason, the variation of the key shape which comprises the lock mechanism 130 can be increased to a great variety, and since the lock mechanism 130 can be locked more reliably, the antitheft property of the card | curd 40 can be improved further. .

  Further, in the release key 152 and the lock bolt 154, when the first cam 158 and the second cam 160 and the shapes of the first cam receiving ring 166 and the second cam receiving ring 168 corresponding thereto are prepared, Variations in shape can be further increased. For example, the convex portion 158b of the first cam 158 constituting the release key 152 has a substantially semicircular shape 180a (see FIG. 18A), a substantially fan-shaped 180b (see FIG. 18B), and a substantially rectangular shape. 180c (see FIG. 18C), 180d (see FIG. 18D) having a substantially rectangular shape with rounded corners, and the like can be changed as appropriate, and the plate thickness can also be changed.

  Next, another mounting structure of the ETC vehicle-mounted device 10a according to the first embodiment will be described with reference to FIGS.

  FIG. 19 is a partially omitted schematic side view in which a vehicle body front portion of a motorcycle 12b to which another mounting structure of the ETC on-vehicle device 10a is applied is enlarged, and FIG. 20 is a partially omitted motorcycle 12b shown in FIG. It is a schematic plan view. 21A is a partially omitted schematic perspective view of the motorcycle 12b shown in FIG. 19, and FIG. 21B is a partially omitted schematic view showing a state in which the cover member 102 of the mounting mechanism 100 is opened from the state shown in FIG. 21A. It is a perspective view. 19 to 22, the same reference numerals as those shown in FIGS. 1 to 18 indicate the same or similar configurations, and thus are described in detail as having the same or similar functions and effects. The same shall apply hereinafter.

  The mounting structure of the ETC in-vehicle device 10a in this case will be described by exemplifying a motorcycle 12b which is a so-called full cowling type saddle riding type vehicle. In the motorcycle 12b, as compared with the above-described motorcycle 12a, the attachment mechanism 100 is used instead of the attachment mechanism 54, and the attachment mechanism 100 (main body portion 42) is fixed on the surface of the front cowl that covers the vehicle body. The point is different.

  As shown in FIGS. 19 and 20, the motorcycle 12b is configured as a full cowling type by being covered with a cowl in the longitudinal direction of the vehicle body. The cowl covers from the front to the top of the head pipe 14, extends from the lower side of the handle 24 to the lower side of the fuel tank 33, and extends from the front cowl 106 to the rear side of the vehicle body. It consists of a lower cowl, rear cowl, etc., not shown. Headlights 108L and 108R are disposed on the front side of the front cowl 106, and blinkers 28L and 28R are disposed below the headlights 108L and 108R. Further, a wind screen 110 is provided above the headlights 108L and 108R, and side mirrors 32L and 32R are disposed on the left and right sides of the wind screen 110, respectively.

  In such a motorcycle 12b, as shown in FIGS. 20 and 21A, an inverted L-shape, that is, extends from the inside in the vehicle width direction to the outside below the handle 24, and then bends downward toward the vehicle body. The mounting mechanism 100 that houses the main body 42 of the ETC vehicle-mounted device 10a is installed on the upper surface 106a of the front cowl 106. The antenna 44 is installed on a wind screen 110 in front of the meter set 31 and a grill 111 provided on the rear surface thereof. Meanwhile, the indicator unit 46 is attached to the upper surface of the grill 111.

  FIG. 22 is an exploded perspective view showing the main body 42 and the attachment mechanism 100 of the ETC on-vehicle device 10a according to the present embodiment.

  The attachment mechanism 100 includes a base bracket 112 that is fixed to the vehicle body (the upper surface 106a of the front cowl 106), and a cover member 102 that is detachably attached to the base bracket 112, and a main body that constitutes the ETC on-vehicle device 10a. The housing structure of 42 is substantially the same as the attachment mechanism 54.

  The base bracket 112 has three attachment portions 116a to 116c that protrude to the front side, the rear side, and the left side of the vehicle body, and the attachment holes 118a to 118c through which the bolts 64 are inserted. Is formed. Therefore, the cover member 102 attached to and detached from the base bracket 112 is formed with bolt cover portions 120a to 120c that are covered from the outside by covering the attachment portions 116a to 116c. In the case of the present embodiment, the bolt cover portions 120a to 120c are individually formed corresponding to the respective attachment portions 116a to 116c. For example, the bolt cover portions 120a to 120c have a large shape that collectively covers the attachment portions 116a to 116c. You can also

  As shown in FIG. 21A, the attachment mechanism 100 has the bottom portion of the base bracket 112 placed on the upper surface 106a of the front cowl 106, and its longitudinal direction (the direction from the hook 68 side to the hook member 77 side) is the longitudinal direction of the vehicle body. Further, the hook member 77 is fixed so as to be disengaged from the upper surface 106a of the front cowl 106, for example, in the vehicle body inner side direction (vehicle body right side direction). 21A and 21B, the opening / closing direction of the lid 90 of the main body 42 and the mounting direction of the cover member 102 with respect to the base bracket 112 are set to be different from each other by approximately 90 °. Note that the signal cables 48 and 50 and the power cable 52 all extend rearward from the rear surface of the mounting mechanism 100 and are then drawn into the front cowl 106 and routed to a predetermined location ( (See FIG. 21B).

  Further, as can be understood from FIGS. 19 and 20, the attachment mechanism 100 in which the main body 42 constituting the ETC on-vehicle device 10a is accommodated is outside the front fork 16L (of course, it may be outside the front fork 16R. ) And is fixed to the vehicle body at a position below the handle 24, and at least a part of the main body portion 42 belongs to the rotation locus range of the handle 24 in plan view.

  Therefore, for example, when passing through the ETC gate 36, even if a communication error occurs between the transmission / reception device 38 of the ETC gate 36 and the ETC on-board unit 10a of the motorcycle 12b, the driver The cover member 102 of the attachment mechanism 100 can be easily opened in the state where it is seated on the card, the lock mechanism 130 is released, the lid 90 is opened, and the card 40 can be removed from the main body 42. In other words, the position where the attachment mechanism 100 (main body portion 42) is installed is set within a range where the driver's hand seated on the seat can easily reach, and the lock bolt 134 is installed in a direction in which the driver can easily operate. Therefore, the ease of handling of the main body 42 can be greatly improved. In the motorcycle 12b, for example, when the vehicle is installed by being rotated by approximately 90 ° from the installation state shown in FIG. 21B such that the buckle 94 side of the main body portion 42 becomes the driver side seated on the seat, the buckle 94 and the lock bolt 134 are installed. Therefore, the ease of handling of the main body portion 42 can be further improved.

  Further, the attachment mechanism 100 is fixed to the upper surface 106a of the front cowl 106 extending in the longitudinal direction of the vehicle body in a state in which the longitudinal direction thereof is along, while the opening / closing direction of the cover member 102 is outside in the vehicle width direction ( (Left side direction) For this reason, after opening the cover member 102 from the base bracket 112, when opening and closing the main body portion 42, it is possible to easily insert a hand from the lower outer space of the handle 24, so that the main body portion 42 can be handled easily. This can be further improved. In this case, the attachment mechanism 100 that accommodates the main body 42 is installed at the rear of the wind screen 110 of the motorcycle 12b and below the handle 24, so that the waterproof effect during traveling can be improved. Further, as in the case of the motorcycle 12a, even in the case of the motorcycle 12b, it is of course possible to install the main body 42 constituting the ETC on-board device 10a in a state exposed to the outside of the motorcycle 12b. It is.

  Further, since the attachment mechanism 100 is fixed to the upper surface 106a of the front cowl 106 in a state in which the longitudinal direction thereof is aligned, the ETC on-vehicle device 10a (attachment mechanism 100) is provided with a vehicle width of the motorcycle 12b. It does not protrude in the direction, and because of its flat shape, it hardly protrudes even when directed upward from the upper surface 106a. For this reason, the attachment mechanism 100 (main body part 42) does not stand out in appearance and does not impair the appearance of the motorcycle 12b, but the attachment mechanism 100 (main body part 42) does not become completely invisible from the outside. Therefore, the driver can appeal that the ETC in-vehicle device 10a is mounted on the surroundings.

  Of course, in the motorcycle 12b in this case as well, the main body 42 does not block the space around the handle 24, so that it does not obstruct the mounting of other electronic devices such as a navigation system and audio speakers. .

  Next, the ETC vehicle-mounted device 10b as the vehicle-mounted communication device according to the second embodiment of the present invention will be described. FIG. 23 is a partially omitted schematic perspective view in which a vehicle front portion of a motorcycle 12c equipped with the ETC on-vehicle device 10b according to the second embodiment is enlarged, and FIG. 24 is a schematic view of the motorcycle 12c shown in FIG. It is a partially omitted schematic side view.

  As shown in FIGS. 23 and 24, the motorcycle 12c supports a pair of front forks 216L and 216R via a head pipe 214 that is pivotally supported in front of a vehicle body frame (not shown) constituting the vehicle body. A handle 218 is supported on the handle 218 in a steerable manner, and a switch 219 is provided on the handle 218. A headlight 220 is disposed in front of the head pipe 214, and a meter set 222 in which various meters are disposed is disposed above the headlight 220. Also, rearview mirrors 224L and 224R are attached to the inside of the grips on both ends of the handle 218, respectively.

  In the handle 218, the ETC vehicle-mounted device 10b according to the present embodiment is fixed via a bracket 226 on the right side of the vehicle body with respect to the center axis in the vehicle width direction and on the center axis side of the rearview mirror 224R. For example, the mounting portion 226a of the bracket 226 is fixed to the pipe portion of the handle 218 by a bolt or the like. Note that reference numeral 227 in FIG. 23 indicates a fuel tank.

  Therefore, the motorcycle 12c automatically communicates with an external communication station, for example, the transmitting / receiving device 38 of the ETC gate 36 provided at the toll gate when passing through the toll gate on the toll road via the ETC on-board device 10b. can do.

  FIG. 25 is a schematic perspective view of the ETC vehicle-mounted device 10b according to the second embodiment, and FIG. 26 is a schematic perspective view of the ETC vehicle-mounted device 10b shown in FIG. 25 with the lid 238 opened. . 27 is a schematic perspective view of the ETC vehicle-mounted device 10b shown in FIG. 25 as viewed from the bottom surface side, and FIG. 28 is a schematic view along the card insertion direction (vehicle body longitudinal direction) of the ETC vehicle-mounted device 10b shown in FIG. It is sectional drawing.

  As shown in FIGS. 25 and 26, the ETC on-vehicle device 10b according to the present embodiment has a hollow box-like case 230 that constitutes its appearance, and a front surface 230a that is a side surface of the case 230 on the rear side of the vehicle body. Corresponds to the shape of the card 40 in the short direction (width direction), and a card insertion slot 234 in which a substantially elliptical widened portion is formed at the center is opened. The shape of the case 230 and its internal space is a vertically long rectangular shape, and the longitudinal direction thereof is configured to be along the longitudinal direction of the vehicle body. Naturally, the card 40 is inserted so that the longitudinal direction thereof is along the longitudinal direction of the vehicle body. It is inserted from the mouth 234 into the case 230.

  The front surface 230 a (card insertion slot 234) of the case 230 is opened and closed by a lid 238 that is swingably provided on the case 230 via a pair of hinges 236 and 236. The hinge 236 supports the lid 238 in a swingable manner by a projection 236 a protruding from the lid 238 toward the case 230 engaging with a shallow recess 236 b provided on the side of the case 230 ( (See FIG. 26).

  The lid body 238 is fixed at the closed position by the engaging action of the hook member 237 provided on the lid body 238 side and the substantially semi-cylindrical protrusion 239 provided on the back side of the case 230 (see FIG. 27) and is held in close contact with the case 230. That is, the hook member 237 and the protrusion 239 function as a holding body (holding mechanism) that fixes the lid 238 in a closed state. As such a holding body, any member can be used as long as the lid 238 can be opened and closed and can be fixed at the closed position. For example, a magnet is used instead of the protrusion 239 and a metal member is used instead of the hook member 237. A configuration using a hook member can be exemplified. In addition, the holding body may be configured to fix both side portions of the lid body 238 and both side surfaces of the case 230 in the vehicle width direction.

  Further, a lock mechanism 130 is provided between the lid 238 and the case 230 to lock the lid 238 in the closed position. As can be understood from FIGS. 25 and 26, in the ETC on-vehicle device 10 b according to the present embodiment, the lock bolt 134 constituting the lock mechanism 130 is provided on the lid 238 side, while the nut 132 is provided in the case 230. As a result, the lid 238 can be locked.

  As shown in FIG. 27, two insert nuts 240 to which bolts for fixing the ETC vehicle-mounted device 10b to the bracket 226 are fastened are diagonally embedded on the back surface (bottom surface) of the case 230.

  In such an ETC vehicle-mounted device 10b, as shown in FIG. 28, the internal space of the case 230 is divided into two upper and lower stages by a partition plate (partition member) 242 provided at a substantially central position in the height (thickness) direction. It is divided into.

  The upper side partitioned by the partition plate 242 is configured as a sealed space 243 that is substantially cut off from the outside and waterproofed. In the sealed space 243, a CPU 244, an antenna 246, a connector 248, and the like are disposed. An electronic circuit (printed circuit board, circuit board) 250 is disposed. As shown in FIG. 32, the electronic circuit 250 is fixed on the partition plate 242 with bolts 250a and nuts 250b via bushes 249a and 249b. The bushes 249a and 249b are, for example, buffer members (elastic members) made of a gel material or a rubber material, and vibrations from the motorcycle 12c transmitted to the electronic circuit 250 through the case 230 (partition plate 242). It has a function to attenuate. Moreover, if the capacitor | condenser, coil, etc. which are not illustrated of the electronic circuit 250 are reinforced by bonding, for example, the vibration resistance of the ETC onboard equipment 10b can be improved further.

  The CPU 244 is an arithmetic command unit that performs various controls of the ETC on-vehicle device 10b. The antenna 246 is a communication antenna that transmits and receives information between the ETC vehicle-mounted device 10 b and the transmission / reception device 38 of the ETC gate 36. The antenna 246 is, for example, a pattern antenna formed by etching on the electronic circuit 250. When the ETC on-board unit 10b is arranged in the horizontal direction, the antenna 246 is directed obliquely upward (in the direction of arrow A in FIG. 28). The directivity is given electrically or physically, and the radiation angle θ is about 20 °. The connector 248 functions as a contact for electrically connecting the electronic circuit 250 and the IC chip 40a which is a terminal of the card 40, and a spring contact 248a protruding from the back side of the electronic circuit 250 is It protrudes to the lower side through a hole formed in the partition plate 242. In this case, the card 40 can read various information of the recorded user and the like, and can write the toll gate passage information received from the transmitting / receiving device 38 of the ETC gate 36 via the ETC on-board device 10b. This is a so-called IC card on which an IC chip 40a is mounted (see FIG. 26).

  In this case, the nut 132 constituting the lock mechanism 130 is also disposed in the sealed space 243, and therefore the rear end side of the nut 132 is sealed in a waterproof state by the seal cap 138.

  On the other hand, as shown in FIG. 28, in the case 230, the lower side partitioned by the partition plate 242 is partially open space (open space, semi-sealed space) communicating with the outside through the card insertion port 234. 252. In other words, the partially open space 252 is a card insertion / removal space in which the card 40 is inserted / removed, and various parts arranged in the partially open space 252 have rainwater or the like invaded from the card insertion port 234. It is assumed to be waterproof.

  In such a partially open space 252, when the card 40 is inserted, the card 40 is held in the case 230 (in the partially open space 252), and the card is linked to the operation of the eject button 256. A card holding / extracting mechanism 258 for projecting the card 40 from the card insertion slot 234 and a card guide 260 for guiding the movement (sliding) operation of the card 40 inserted or ejected through the card insertion slot 234 are provided. This card guide 260 is fixed to the lower surface side of the partition plate 242, and is composed of a pair of L-shaped members arranged to face each other in the width direction dimension of the card 40 (see FIG. 29).

  Further, in the partially open space 252, a waterproof speaker 262 for announcing to the driver the passing information and passing history of the ETC gate 36, rainwater and the like that has entered from the card insertion slot 234 are contained in the partially open space 252. A drainage port (drainage portion) 264 is provided for discharging from the case 230 to the outside.

  The waterproof speaker 262 is waterproof because it is partially installed in the open space 252, and is connected to the electronic circuit 250 by a speaker cable (not shown) through a hole (not shown) formed in the partition plate 242. ing. The peripheral portion of the hole portion of the partition plate 242 through which the speaker cable passes is also waterproofed to prevent water from entering the sealed space 243 on the upper side. Similarly, the spring contact 248a protruding into the partially open space 252 from the connector 248 has a waterproof structure on the partially open space 252 side including the hole provided in the partition plate 242 through which the spring contact 248a passes. As shown in FIG. 27, a plurality of small holes 266 are provided on the bottom surface of the case 230 corresponding to the waterproof speaker 262. Depending on the installation position of the waterproof speaker 262, a small hole 266a (see the broken line in FIG. 25) may be formed on the side surface of the case 230 in the vehicle width direction instead of the small hole 266. In this case, since the waterproof speaker 262 is fixed to the inner wall of the case 230 in the vehicle width direction, it is possible to effectively prevent the waterproof speaker 262 from being completely submerged even when the partially open space 252 is submerged. Can do.

  Depending on the shape of the lid 238 and the front surface 230 a of the case 230, the nut 132 constituting the lock mechanism 130 may be partially disposed in the open space 252. In this case, since it is not necessary to provide the seal cap 138 specially on the rear end side of the nut 132, the structure of the lock mechanism 130 can be simplified.

  As shown in FIG. 27 and FIG. 28, for example, two drain outlets 264 are provided at both ends of the case 230 on the front side of the vehicle body and open to the bottom surface of the case 230. Such a drain port 264 protrudes from the bottom surface of the case 230 and closes the front side of the vehicle body, and is covered by a drain cover 268 that is opened only on the rear side of the vehicle body. Prevents backflow of rainwater and so on.

  Furthermore, an opening 270 for drawing the power cable 269 of the ETC on-vehicle device 10b out of the case 230 is provided on the bottom surface of the case 230. That is, the power cable 269 passes from the electronic circuit 250 through a part of the open space 252 through a hole (not shown) formed in the partition plate 242, and then is drawn out of the case 230 from the opening 270. In this case, a plurality of groove portions 272 a to 272 c that are continuous from the opening 270 to a plurality of side surfaces of the case 230 are formed. That is, by selecting one of the groove portions 272a to 272c according to the mounting position of the ETC on-vehicle device 10b in the motorcycle 12c, the drawing position of the power cable 269 can be appropriately changed, and the ETC on-vehicle device 10b Installation flexibility is improved.

  Returning to FIG. 26, a pair of LED lamps 274 </ b> L and 274 </ b> R (not shown) disposed in the electronic circuit 250 are provided at both ends of the front surface 230 a of the case 230 corresponding to the sealed space 243 on the upper side of the card insertion slot 234. A pair of windows 276L and 276R for transmitting the light of FIG. 28 and FIG. 29 to the outside of the case 230 are provided. The LED lamps 274L and 274R, for example, are such that one (left side in FIG. 29) LED lamp 274L emits red light, and the other (right side in FIG. 29) LED lamp 274R emits green light. To the driver.

  Between the pair of windows 276L and 276R, for example, a volume button 278 and a history button 280 formed by rubber buttons are provided. The volume button 278 and the history button 280 are connected to the volume switch 279 and the history switch 281 provided in the electronic circuit 250 (see FIG. 29), and the volume switch 279 and the history button 280 are kept in an airtight state of the sealed space 243. The history switch 281 is operated from the outside of the case 230.

  Furthermore, the window 276L and 276R of the lid 238 are supported so that the driver can surely see the lighting state of the LED lamps 274L and 274R even when the lid 238 is closed, for example, while the motorcycle 12c is running. The lid side window portions 282L and 282R are provided at the positions to be operated. In this case, in the ETC vehicle-mounted device 10b, the windows 276L, 276R, and 276R are provided so that the driver can always reliably recognize the lighting state of the LED lamps 274L and 274R without depending on the driver's physique or sitting posture. At least one of the lid side window portions 282L and 282R is a non-directional lens having a convex or concave curved surface.

  As shown in FIG. 26, a packing 284 made of a horizontally-long rectangular frame bordering the periphery of the card insertion slot 234 is fixed to the back surface (front surface 230a side) of the lid 238. The packing 284 is a seal member for preventing rainwater and the like from entering the card insertion slot 234 when the lid 238 is closed. The packing 284 includes a card insertion slot 234 including the widened portion and an eject button 256 described later. It is in close contact with the front surface 230a so as to surround it. The packing 284 may be provided on the front surface 230a side of the case 230, or may be shaped so as not to surround the eject button 256 and to border the outer edge of the card insertion slot 234 including the widened portion.

  Next, the card holding / extracting mechanism 258 of the ETC in-vehicle device 10b according to the present embodiment will be described.

  As shown in FIGS. 28 to 31, the card holding / removing mechanism 258 includes a card lock mechanism 286 disposed in the vicinity of the card insertion slot 234 on the rear end side (rear side of the vehicle body) in the card 40 insertion direction, A card crimping mechanism 288 disposed in the vicinity of the spring contact 248a on the distal end side (vehicle body front side) in the insertion direction.

  The card lock mechanism 286 has a rotation shaft 292 supported at both ends by a support member 290 and a claw member 294 that is formed in a substantially L shape and can swing in the direction of arrow B in FIG. And a spring 296 connected to one surface side (the vehicle body front side) of the lower end side of the claw member 294, and a spring support member 298 to which the other end side of the spring 296 is fixed.

  In the claw member 294, an eject button 256 is connected to the other surface side of the spring 296. Further, the claw member 294 has a curved inclined surface 294a that is curved and inclined toward the rear end side (rear side of the vehicle body) in the insertion direction of the card 40, and a notch shape that is continuous from the curved inclined surface 294a to the rear side of the vehicle body. And a lock surface 294b.

  The spring 296 biases the lower end side of the claw member 294 toward the rear end side (rear side of the vehicle body) in the insertion direction of the card 40, that is, the claw member 294 is rotated by the urging force of the spring 296. Is biased upward in the direction of arrow B.

  On the other hand, the card crimping mechanism 288 is formed wider than the rotary shaft 302 supported at both ends by the support member 300 and the claw member 294 (see FIGS. 29 and 30). 28, a cam member 304 swingable in the direction of arrow C, a spring 306 connected to one end surface (vehicle body front side) of the cam member 304, and a rear surface side (vehicle body front side) facing the front surface 230a of the case 230. ) And a spring support member 308 to which the other end of the spring 306 is fixed. The support member 300 is formed with a hole 300a through which the spring 306 passes.

  In the cam member 304, the cam member 304 extends in the direction of arrow C on the upper surface (partition plate 242 side) on the rear end side (rear side of the vehicle body) in the card insertion direction opposite to the one surface side to which the spring 306 is connected. When swinging upward, a crimping surface 304a is formed which comes into contact with the card 40 inserted into the case 230 in a parallel plane (see FIGS. 30 and 31). A cushion member 310 is fixed to the crimping surface 304a (see FIG. 30). Further, a stop surface 304b with which the tip of the card 40 abuts is formed on the opposite side of the surface of the cam member 304 to which the spring 306 is connected. The distance between the stop surface 304b and the lock surface 294b is set to be equal to or slightly longer than the longitudinal length of the card 40, with a linear distance along the longitudinal direction of the vehicle body.

  The spring 306 biases the cam member 304 toward the rear end side (rear side of the vehicle body) in the insertion direction of the card 40. That is, the cam member 304 is centered on the rotating shaft 302 by the biasing force of the spring 306. And urged downward in the direction of arrow C.

  Next, the operation of the ETC on-vehicle device 10b according to the present embodiment basically configured as described above will be described.

  First, in a state where the motorcycle 12c is stopped, the driver releases the lock mechanism 130 using the release key 148, opens the lid 238, and puts the card 40 from the card insertion slot 234 into the case 230 in a predetermined direction. (See arrow D in FIG. 28). Then, the card 40 is gradually inserted to the back of the case 230 while being guided by the card guide 260. At this time, in the card lock mechanism 286, the card 40 follows the curved inclined surface 294a of the claw member 294. Therefore, the curved inclined surface 294a is pressed downward in the arrow B direction. As a result, the claw member 294 is swung downward in the direction of arrow B about the rotation shaft 292 against the urging force of the spring 296. For this reason, the card 40 is smoothly inserted into the case 230 without being restricted by the claw member 294. At this time, since the widened portion is formed at the center of the card insertion slot 234, the driver can more easily push the card 40 into the case 230.

  As shown in FIG. 31, when the card 40 is completely inserted into the case 230, the leading end of the card 40 presses the stop surface 304 b of the cam member 304 constituting the card crimping mechanism 288. As a result, the cam member 304 swings upward in the direction of arrow C against the urging force of the spring 306 about the rotation shaft 302. Therefore, the back surface side (lower surface side) of the card 40 is pressed upward by the crimping surface 304 a of the oscillating cam member 304, and the IC chip 40 a provided on the front surface side (upper surface side) is connected to the connector 248. It is crimped to the spring contact 248a.

  At the same time, since the card 40 gets over the curved inclined surface 294 a of the claw member 294, the rear end portion of the card 40 comes into contact with the lock surface 294 b of the claw member 294. In other words, the lock surface 294 b of the claw member 294 engages with the rear end portion of the card 40.

  Accordingly, the card 40 is securely held between the lock surface 294b of the claw member 294 and the stop surface 304b of the cam member 304. At this time, the lock surface 294b and the stop surface 304b are biased by the spring 296 and the spring 306, respectively, in the direction of sandwiching the card 40 from the front and rear sides. As a result, the card 40 can be elastically gripped at the front and rear end portions in the insertion direction, and can be prevented from being displaced due to vibration or the like during traveling of the motorcycle 12c. It can be held stably.

  Moreover, in such a state, the cam member 304 is held in a posture in which the crimping surface 304a crimps the IC chip 40a portion of the card 40 to the spring contact 248a from the back side via the cushion member 310. For this reason, since the card 40 is securely crimped to the spring contact 248a side centering on the IC chip 40a portion, the IC chip 40a and the spring contact 248a cause poor contact due to vibration of the motorcycle 12c, etc. It is possible to reliably prevent the reading failure of the card 40.

  By the way, in order to further improve the contact between the IC chip 40a and the spring contact 248a, the ETC in-vehicle device 10b moves the case 230 and the card guide 260 in the direction indicated by the arrow F in FIG. 28 or the arrow G in FIG. It can be intentionally bent somewhat in the direction. Then, due to the above-described bending shape of the case 230 and the card guide 260, the card 40 inserted into the case 230 is similarly bent, and as a result, the surface side (upper surface side) on which the IC chip 40a is disposed. Protrudes toward the upper spring contact 248a. Thereby, the contact property between the IC chip 40a and the spring contact 248a can be further improved. In FIGS. 28 and 29, the amount of bending of the card guide 260 is emphasized for easy understanding.

  In the ETC in-vehicle device 10b, as shown in (1) of FIG. 33, when the card 40 is normally inserted into the case 230, the red LED lamp 274L is turned off and the green LED lamp 274R is turned on. Light. As shown in (2) of FIG. 33, when the card 40 is not inserted, the red LED lamp 274L is turned on and the green LED lamp 274R is turned off. Furthermore, as shown in (3) of FIG. 33, when there is a device abnormality such as an abnormality in the ETC on-vehicle device 10b itself, the red LED lamp 274L blinks and the green LED lamp 274R turns off. . As a result, the driver can reliably grasp the normal insertion of the card 40, the operating state of the ETC on-board device 10b, and the like.

  Therefore, after the card 40 is normally inserted into the case 230, first, the lid 238 is brought into contact with the front surface 230a of the case 230 by the engaging action of the hook member 237 that is the holder of the lid 238 and the protrusion 239. Hold tightly against. Next, for example, the cover 238 is securely locked to the case 230 by rotating the lock bolt 134 with the release key 148 connected to the ignition key. Thereafter, when the motorcycle 12c passes through the ETC gate 36, the ETC on-board device 10b reads information recorded on the card 40, for example, information on the section of the toll road that has traveled, information on the vehicle type and card company, etc. At the same time, the information is notified to the transmitting / receiving device 38 of the ETC gate 36 via the antenna 246. As a result, the transmission / reception device 38 determines the toll for the motorcycle 12c and performs a predetermined process for charging a travel card to a predetermined card company. At this time, the ETC in-vehicle device 10b generates a notification sound (beep sound or the like) via the waterproof speaker 262 at a volume that is sufficiently audible even when a helmet is worn, for example. For this reason, the driver can recognize normal passing of the ETC gate 36 in a state where the driver concentrates on driving the vehicle.

  Further, when a notice gate (notice antenna) for notifying the installation of the ETC gate 36 is installed in front of the ETC gate 36 or in the middle of the road, for example, the card 40 is not inserted even when the notice gate passes. The driver is notified of a warning sound or the like via the waterproof speaker 262. Conventionally, the ETC vehicle-mounted device corresponding to a motorcycle does not have a function of notifying or warning the operation state by voice or the like, but the ETC vehicle-mounted device 10b according to the present embodiment has a waterproof speaker in the case 230. By providing 262, the driver can more easily grasp the operating state of the ETC vehicle-mounted device 10b.

  Next, the motorcycle 12c that has passed through the ETC gate 36 and has gone out of the toll road is stopped, the lock mechanism 130 is released with the release key 148, and the cover 238 is opened. When confirming, the history button 280 provided on the front surface 230a of the case 230 is pressed. That is, every time the history button 280 is pressed, the travel history, fee, etc. are notified by voice through the waterproof speaker 262. Such sound volume can be easily changed by pressing the volume button 278. In the case of the ETC in-vehicle device 10b according to the present embodiment, every time the volume button 278 is pressed, the volume is sequentially controlled in five stages and can be set to a desired volume. Note that it is preferable that the notification sound when passing through the ETC gate 36 is surely heard by the driver while traveling. For example, the volume of the waterproof speaker 262 is set to a low level by the volume button 278. Even in this state, it is possible to perform control such that only the notification sound is notified at the maximum volume.

  When the use of the ETC on-vehicle device 10b is finished and the card 40 is removed from the case 230, the lock mechanism 130 is released, the lid 238 is opened, and the eject button 256 is pushed. Then, the claw member 294 constituting the card lock mechanism 286 is swung downward in the direction of arrow B about the rotation shaft 292 against the biasing force of the spring 296, so that the card 40 is locked by the lock surface 294b. It is released (see FIG. 28). As a result, the cam member 304 constituting the card crimping mechanism 288 is reflected and oscillated downward in the direction of arrow C about the rotation shaft 302 by the biasing force of the spring 306. Accordingly, the card 40 is released from the crimping surface 304a of the cam member 304 to the card insertion slot 234 side (in the direction of arrow E in FIG. 28) due to the reaction of the cam member 304 from the stop surface 304b. A predetermined distance is discharged (projected). Therefore, the driver can easily remove the card 40 from the ETC in-vehicle device 10b.

  As described above, according to the ETC vehicle-mounted device 10b according to the present embodiment, the connector 248 having the spring contact 248a electrically connected to the IC chip 40a of the card 40 inserted into and removed from the case 230, the CPU 244, etc. An electronic circuit 250 provided and an antenna 246 that communicates with an external communication station, for example, the transmitting / receiving device 38 of the ETC gate 36, are integrally incorporated in the case 230. That is, in the ETC in-vehicle device 10b, it is not necessary to provide a communication cable that connects the main body unit and the antenna unit. Therefore, it can be effectively avoided that the communication cable is repeatedly bent and damaged due to steering or the like to cause a communication failure, a function stop, an error, or the like.

  Furthermore, the card insertion slot 234 through which the card 40 is inserted / removed can be opened / closed by the lid 238, and the waterproofness of the card insertion slot 234 is ensured by the packing 284 when the lid 238 is in the closed position. Is done. Moreover, the lid 238 can be tightly held with respect to the front surface 230a of the case 230 by the engaging action of the hook member 237 functioning as a holding body and the protrusion 239, and can be securely locked by the lock mechanism 130. can do. The front surface 230a and the card insertion slot 234 of the case 230 are directed toward the rear side in the running direction of the motorcycle 12c (the driver side seated on the seat), and the lock bolt 134 constituting the lock mechanism 130 is also provided. The head 134a is in a state facing the driver side. For this reason, each operation such as locking / unlocking of the locking mechanism 130, opening / closing of the cover 238, insertion / removal of the card 40, etc. is easy, and the effect that rainwater infiltration during traveling can be prevented more reliably is also achieved. can get.

  Furthermore, since the ETC on-board device 10b is provided with the same locking mechanism 130 as the ETC on-vehicle device 10a, the flange 142 provided in the wall portion 140 of the ETC on-vehicle device 10b is temporarily destroyed. In addition, it is possible to hold the lid 238 in the closed position by the engaging action of the hook member 237 and the protruding portion 239, and it is easily repaired and exchanged simply by removing the lid 238 from the hinge 236 and exchanging it. It can be performed. Naturally, like the wall portion 140 shown by the broken line in FIG. 10B, only the wall portion 140 and the lock bolt 134 are press-fitted into the hole formed in the lid 238, and only the wall portion 140 and the like can be removed and replaced. You may comprise.

  Further, in the ETC on-board device 10b, the inside of the case 230 is partitioned by a partition plate 242, a sealed space 243 in which the electronic circuit 250 and the like are disposed, a partially open space 252 that communicates with the card insertion slot 234 and the card 40 is inserted and removed. It is divided into. For this reason, even in rainy weather, even when rainwater or the like enters the case 230 from the card insertion slot 234 when inserting or removing the card 40, the rainwater does not flow into the upper sealed space 243, It can be discharged out of the case 230 from the partially open space 252 through the drain outlet 264. For this reason, it is possible to prevent the electronic circuit 250 provided with the CPU 244 and the like from being damaged by rainwater.

  Further, in the ETC in-vehicle device 10b, as described above, the main body portion into which the card 40 is inserted and removed and the antenna 246 that communicates with the outside are integrally stored in the case 230, and the lid 238 and the partition plate 242 are used. The waterproofing of the electronic circuit 250 and the like is ensured. Therefore, the ETC in-vehicle device 10b can be easily fixed to the outside of the motorcycle 12c, for example, the handle 218, etc., and can be easily attached even to a vehicle having a small storage space. Therefore, for example, as shown in FIG. 34, the bracket 312 can be used to fix the side of the front fork 216R or 216L of the motorcycle 12c. In this case, the lid 238 is attached to the rear side of the vehicle body. In other words, the front end may be directed upward inward in accordance with the directivity of the antenna 246. As described above, the ETC on-vehicle device 10b can be easily attached to various parts of the vehicle and most types of vehicles different from each other by exchanging only the bracket, and high versatility can be obtained.

  The motorcycle 12c is a vehicle type in which a windshield is not provided in front of the meter set 222, as shown in FIG. For this reason, as shown in FIG. 24, when the ETC vehicle-mounted device 10b is installed so that its longitudinal direction is substantially horizontal, the intrusion into the case 230 from the card insertion slot 234 or the like such as rain water during traveling Can be effectively prevented.

  On the other hand, as shown in FIG. 35, in the motorcycle 12d in which the windshield 311 is provided in front of the meter set 222, the windshield 311 can prevent a certain amount of rainwater or the like from entering the case 230. The angle of 226 can be adjusted, and the antenna 246 built in the ETC on-vehicle device 10b can be installed so as to better point the transmitting / receiving device 38 side of the ETC gate 36.

  In the ETC vehicle-mounted device 10b, the lid 238 is configured to be opened and closed by the hinge 236. For example, as shown in FIG. 36, a resin such as polypropylene (PP) that is substantially integrated with the upper surface of the case 230. It can also be set as the ETC onboard equipment 10c provided with the cover body 238a using the hinge 314 by material.

  Moreover, it goes without saying that the release key 152 and the lock bolt 154 (see FIG. 16) can be used as components of the lock mechanism 130 in the ETC on-board units 10b and 10c in place of the release key 148 and the lock bolt 134. .

  Although the present invention has been described with the above embodiments, the present invention is not limited to this, and it is naturally possible to adopt various configurations without departing from the gist of the present invention.

  In the above embodiments, the nuts 132 are provided on the cases 88 and 230 side and the lock bolts 134 (154) are provided on the lids 90 and 238 side. It is sufficient that the components do not rotate when the lock mechanism 130 is used, and the components provided on the oscillating body side, that is, the lids 90 and 238 side rotate and lock / unlock. The female relationship can be reversed, for example, the arrangement relationship between the nut 132 and the lock bolt 134 (154) can be reversed. In such a case, for example, instead of the nut 132, a so-called cap nut having a head is used, and a lock nut having an operation groove 134c formed on the head is used. Ordinary bolts can be embedded in the case.

  Further, in each of the above embodiments, the present invention has been described by exemplifying so-called naked type and full cowling type motorcycles. However, the in-vehicle communication device according to the present invention is applicable to other types of motorcycles (scooter type and off-road). Of course, it can also be mounted on a type).

  Furthermore, the ETC vehicle-mounted device 10a according to the first embodiment may be a so-called antenna-integrated type in which the antenna 44 is integrally formed with the main body portion 42. Similarly, the ETC vehicle-mounted devices 10b and 10c are provided with an antenna. It is also possible to configure the case 230 as a separate body.
