このような従来の慣性センサ装置では、その互換性の無さが問題となっていた。   In such a conventional inertial sensor device, the lack of compatibility has been a problem.

すなわち、上記従来の慣性センサ装置におけるセンサ素子１は、部品メーカによってその外部電極群２の配置が異なるため、その互換性の無さが問題となってしまっていた。   That is, the sensor element 1 in the conventional inertial sensor device has a problem of incompatibility because the arrangement of the external electrode group 2 differs depending on the component manufacturer.

この構成により、部品メーカごとに前記素子における前記外部電極群の配置が異なったとしても、前記基板における第１の側面に前記端子群が整列される構成となるため、慣性センサ装置の互換性を向上させることができる。   With this configuration, even if the arrangement of the external electrode group in the element is different for each component manufacturer, the terminal group is arranged on the first side surface of the substrate, so that the inertial sensor device is compatible. Can be improved.

（実施の形態１）
以下、本発明の実施の形態１におけるアタッチメント部材と、これを用いた慣性センサ装置、自動車、及びカーナビゲーション装置について図面を参照しながら説明する。 (Embodiment 1)
Hereinafter, an attachment member, an inertial sensor device, an automobile, and a car navigation device using the attachment member according to Embodiment 1 of the present invention will be described with reference to the drawings.

図１に示すごとく、本実施の形態に示すアタッチメント部材は、基板１１と、前記基板１１上に設けられた素子配置部１２とを備え、前記素子配置部１２には、図２に示すような素子１３の外部電極群１４と電気的に接続される第１の端子群１５を有し、前記基板１１における第１の側面１１Ａには前記第１の端子群１５と電気的に接続される第２の端子群１６を有する構成としている。   As shown in FIG. 1, the attachment member shown in the present embodiment includes a substrate 11 and an element arrangement portion 12 provided on the substrate 11, and the element arrangement portion 12 includes the element arrangement portion 12 as shown in FIG. A first terminal group 15 electrically connected to the external electrode group 14 of the element 13 is provided, and a first side surface 11 A of the substrate 11 is electrically connected to the first terminal group 15. Two terminal groups 16 are provided.

また、図３に示すごとく、図１に示したアタッチメント部材における前記素子配置部１２に図２に示した前記素子１３を配置し、前記アタッチメント部材における前記第１の端子群１５と前記素子１３における前記外部電極群１４とを電気的に接続して、本実施の形態における慣性センサ装置を構成することができる。   Further, as shown in FIG. 3, the element 13 shown in FIG. 2 is arranged in the element arrangement portion 12 in the attachment member shown in FIG. 1, and the first terminal group 15 and the element 13 in the attachment member are arranged. The inertial sensor device according to the present embodiment can be configured by electrically connecting the external electrode group 14.

そして、図３に示した前記慣性センサ装置における前記第２の端子群１６に電気的に接続され、前記慣性センサ装置からの出力により制御される車体を備えることにより、本実施の形態における自動車を構成することができる。   The vehicle according to the present embodiment is provided with a vehicle body that is electrically connected to the second terminal group 16 in the inertial sensor device shown in FIG. 3 and is controlled by the output from the inertial sensor device. Can be configured.

さらに、図３に示した前記慣性センサ装置における前記第２の端子群１６に電気的に接続され、前記慣性センサ装置からの出力によりその表示内容が制御されるディスプレイを備えることにより、本実施の形態におけるカーナビゲーション装置を構成することができる。   Furthermore, the present embodiment includes a display that is electrically connected to the second terminal group 16 in the inertial sensor device shown in FIG. 3 and whose display content is controlled by an output from the inertial sensor device. The car navigation apparatus in the form can be configured.

このような構成により、部品メーカごとに前記素子１３における前記外部電極群１４の配置が異なったとしても、前記基板１１における第１の側面１１Ａに前記第２の端子群１６が整列される構成となるため、慣性センサ装置の互換性を向上させることができる。   With such a configuration, even if the arrangement of the external electrode group 14 in the element 13 is different for each component manufacturer, the second terminal group 16 is aligned with the first side surface 11A of the substrate 11. Therefore, the compatibility of the inertial sensor device can be improved.

なお、図４に示すごとく、前記基板１１が斜面１１Ｂを有し、前記素子配置部１２が前記斜面１１Ｂ上に設けられた構成とすることにより、例えばこの慣性センサ装置を自動車に搭載する場合において、この自動車における搭載面１７が図４に示すごとく斜面であるような場合においても、この搭載面１７の傾斜と逆の傾斜を前記基板１１における前記斜面１１Ｂに設けることにより、前記慣性センサ装置の検知精度を担保することができ、高精度に前記自動車やカーナビゲーション装置を制御することができる。   As shown in FIG. 4, when the substrate 11 has a slope 11B and the element placement portion 12 is provided on the slope 11B, for example, when the inertial sensor device is mounted on an automobile. Even in the case where the mounting surface 17 in the automobile is an inclined surface as shown in FIG. 4, by providing the inclined surface 11B of the substrate 11 with an inclination opposite to the inclination of the mounting surface 17, the inertial sensor device Detection accuracy can be ensured, and the automobile and the car navigation device can be controlled with high accuracy.

なお、本実施の形態においては前記基板１１が前記斜面１１Ｂを有する構成として説明したが、前記基板１１を、斜面を有する台座（図示せず）に取り付けることにより、同様の構成としても構わない。   In the present embodiment, the substrate 11 has been described as having the inclined surface 11B. However, the substrate 11 may be mounted on a pedestal (not shown) having an inclined surface to have the same configuration.

さらに、図５に示すごとく、前記基板１１における前記斜面１１Ｂの傾斜角度を９０度にすることにより、基板実装性の向上を図ることができる。即ち、例えば前記素子１３が角速度センサの場合、前記素子１３の構造上の違いによって、その素子１３の検知できる軸と前記素子１３の搭載面との関係が異なる。したがって、図６に示すごとく、ポータブルカーナビゲーション装置のディスプレイ部分１８内にこのディスプレイ部分１８平面に平行に埋設された実装基板（図示せず）に前記素子１３を搭載するような場合、前記素子１３の構造によっては、前記実装基板に対して素子１３を垂直に実装する必要がある場合がある。そのような場合、図５に示すような傾斜角度が９０度である前記基板１１を有しない素子１３をそのまま前記実装基板に実装するわけであるが、前記実装基板とこの実装基板に対して垂直に実装される前記素子１３との実装面積が非常に小さくなってしまい基板実装性が悪くなってしまうが、図５、６に示すごとく、傾斜角度が９０度である前記基板１１を用いることにより、実装基板との実装面積を確保し、実装信頼性を向上させることができるのである。また、前記実装基板に対して前記素子１３を直接垂直に実装するような場合には、その垂直性を担保することが難しく、当該垂直性が損なわれた場合には検知精度の低下を生んでしまうことになるが、上述のような傾斜角度が９０度である前記基板１１を用いることにより、当該垂直性を担保し、検知精度の低下を抑制することができるのである。   Further, as shown in FIG. 5, by making the inclination angle of the inclined surface 11B in the substrate 11 90 degrees, the substrate mountability can be improved. That is, for example, when the element 13 is an angular velocity sensor, the relationship between the axis that can be detected by the element 13 and the mounting surface of the element 13 varies depending on the structure of the element 13. Therefore, as shown in FIG. 6, in the case where the element 13 is mounted on a mounting board (not shown) embedded in the display portion 18 of the portable car navigation apparatus in parallel to the plane of the display portion 18, the element 13 Depending on the structure, it may be necessary to mount the element 13 perpendicularly to the mounting substrate. In such a case, the element 13 without the substrate 11 having an inclination angle of 90 degrees as shown in FIG. 5 is mounted on the mounting substrate as it is, but the mounting substrate and the mounting substrate are perpendicular to each other. As shown in FIGS. 5 and 6, the mounting area with the element 13 mounted on the substrate becomes very small and the substrate mounting property is deteriorated. However, as shown in FIGS. Therefore, it is possible to secure a mounting area with the mounting substrate and improve mounting reliability. Further, when the element 13 is mounted directly perpendicularly to the mounting board, it is difficult to ensure the verticality, and when the verticality is impaired, the detection accuracy is lowered. However, by using the substrate 11 having an inclination angle of 90 degrees as described above, it is possible to ensure the perpendicularity and to suppress a decrease in detection accuracy.

本発明のアタッチメント部材と、これを用いた慣性センサ装置、自動車、及びカーナビゲーション装置は、慣性センサ装置の互換性を向上させることができるという効果を有し、自動車、カーナビゲーション装置等において有用である。   The attachment member of the present invention and an inertial sensor device, an automobile, and a car navigation device using the attachment member have an effect of improving the compatibility of the inertial sensor device, and are useful in an automobile, a car navigation device, and the like. is there.
