Description
本発明は、電子天秤に関し、特に外観を構成する筐体を備える電子天秤（電子はかりとも呼ばれることもある）に関する。 The present invention relates to an electronic balance, and more particularly, to an electronic balance (sometimes referred to as an electronic balance) including a housing that forms an appearance.
電子天秤においては、平面視で長方形状の基準ベースと、その基準ベースの上方を覆うように取り付けられ、上面を有する四角筒状（箱状）の筐体と、被測定物を載置するための測定皿（荷重受け）と、その基準ベースの四隅に下方から取り付けられる４個の水平調整脚とを備え、基準ベースと筐体との内部に、荷重検出センサ、センサ出力演算モジュール、情報画像を表示する表示部を有する表示器モジュール、電源モジュール、水平であるか否かを測定するための水平調整器等の機能部品を収容したものが知られている。
このような電子天秤の一例として、荷重検出センサ、センサ出力演算モジュール、電源モジュール、水平調整器、荷重受け及び水平調整脚は、基準ベースに固定され、表示器モジュールは、筐体に固定されるとともに基準ベースにコード接続されるものがある。つまり、筐体の上面と表示器モジュールの表示部とが同一平面となるように、筐体と表示器モジュールとの位置合わせを予め行い一体化させることで、表示器モジュールを有する筐体が基準ベースに上方から取り付けられる。
また、電子天秤の他の一例として、スイッチ基板や表示器モジュール等も筐体に固定されているものがある（例えば、特許文献１参照）。これにより、コード接続等を行わず、スイッチ基板や表示器モジュールを基準ベースに簡易に接続することができる。
As an example of such an electronic balance, a load detection sensor, a sensor output calculation module, a power supply module, a horizontal adjuster, a load receiver and a horizontal adjustment leg are fixed to a reference base, and a display module is fixed to a housing. Some are corded to the reference base. That is, by aligning the housing and the display module in advance and integrating them so that the upper surface of the housing and the display portion of the display module are in the same plane, the housing having the display module becomes the reference. Attached to the base from above.
As another example of an electronic balance, a switch board, a display module, and the like are also fixed to a housing (for example, see Patent Document 1). Accordingly, the switch board and the display module can be easily connected to the reference base without performing a cord connection or the like.
しかしながら、上述したような電子天秤では、基準ベースが下部の筐体の役割も果たしているため、外観形状である意匠の変更を行う場合には、上方から取り付ける筐体だけでなく、基準ベースの変更も行わなければなかった。さらに、基準ベースの変更を行えば、基準ベースに搭載される機能部品の配置の変更等も行わなければならなかった。つまり、意匠と、はかりの性能とが分離されていないので、容易に意匠のみの変更を行うことができなかった。
そこで、本発明は、意匠を構成する筐体と、天秤の性能を達成するための機能部品を搭載する基準ベースとを分離することによって、筐体の意匠のみや、機能部品による天秤の性能のみの変更を容易に行うことができる電子天秤を提供することを目的とする。
However, in the electronic balance as described above, the reference base also plays the role of the lower housing. Therefore, when changing the design of the external appearance, not only the housing attached from above, but also the change of the reference base I had to do it. Furthermore, if the reference base is changed, the arrangement of functional components mounted on the reference base must be changed. That is, since the design and the performance of the scale are not separated, it was not possible to easily change only the design.
Therefore, the present invention separates the housing constituting the design from the reference base on which the functional components for achieving the performance of the balance are separated, so that only the design of the housing and the performance of the balance using the functional components are obtained. It is an object of the present invention to provide an electronic balance that can be easily changed.

本発明の電子天秤によれば、基準ベースには、天秤の性能を達成するための機能部品が搭載される。一方、筐体には、機能部品は全く搭載されない。そして、機能部品が搭載された基準ベースは、例えば、左右や上下から第一筐体と第二筐体とにより包み込まれる。 According to the electronic balance of the present invention, the functional component for achieving the performance of the balance is mounted on the reference base. On the other hand, no functional component is mounted on the housing. Then, the reference base on which the functional component is mounted is wrapped by, for example, the first casing and the second casing from the left and right and the top and bottom.
以上のように、本発明の電子天秤によれば、意匠を構成する筐体と、天秤の性能を達成するための機能部品を搭載する基準ベースとを分離することによって、意匠のみや、機能部品による天秤の性能のみの変更を容易に行うことができる。例えば、意匠の変更を行いたい場合には、機能部品を搭載する基準ベースはそのまま使用して、第一筐体及び第二筐体を変更することになる。 As described above, according to the electronic balance of the present invention, only the design or the functional component can be obtained by separating the casing constituting the design and the reference base on which the functional component for achieving the performance of the balance is mounted.

The display module 23 displays an information image on the display unit based on the calculation result by the sensor output calculation module 27.
The level adjuster 24 measures whether or not it is horizontal, and water and air are enclosed in a hemispherical container. Therefore, if it is horizontal, air will come to the center in a plan view, and if it is not horizontal, air will not come to the center in a plan view.
測定皿４０は、下面の中心から下方に伸びる連結軸（図示せず）を有する円板形状であり、その上面には被測定物が載置されることになる。
各水平調整脚５０は、上面の中心から上方に伸びるネジ軸を有する円板形状であり、床等に置かれる。そして、水平調整脚５０は、ネジ受部３０ａに螺合されることにより取り付けられることになる。このとき、水平調整脚５０のネジ受部３０ａへの螺合の度合いにより、高さが調整される。すなわち、４個の水平調整脚５０のそれぞれのネジ受部３０ａへの螺合の度合いで、水平が調整されることになる。

なお、基準ベース２９には、スイッチ基板等が搭載されていてもよく、このとき、第一筐体１０には、スイッチ用の貫通孔が形成されたり、くり抜き部が形成されたりする。
Through holes 30 a are respectively formed at the four corners of the lower surface of the second housing 30. Each through hole 30a is a circular hole into which the screw shaft of the horizontal adjustment leg 50 is inserted. Accordingly, the horizontal adjustment leg 50 is disposed below the second housing 30 and is fixed to the screw receiving portion 30 a of the reference base 29.
Note that a switch substrate or the like may be mounted on the reference base 29, and at this time, a through hole for a switch or a cut-out portion is formed in the first housing 10.
以上のように、電子天秤によれば、意匠を構成する第一筐体１０及び第二筐体３０と、天秤の性能を達成するための機能部品２０を搭載する基準ベース２９とを分離することによって、第一筐体１０及び第二筐体３０の意匠のみや、機能部品２０によるはかりの性能のみの変更を容易に行うことができる。例えば、意匠の変更を行いたい場合には、機能部品２０を搭載する基準ベース２９はそのまま使用して、第一筐体１０及び第二筐体３０を、上面を有する円筒状の第一筐体及び下面を有する円筒状の第二筐体に変更することができる。 As described above, according to the electronic balance, the first casing 10 and the second casing 30 constituting the design are separated from the reference base 29 on which the functional component 20 for achieving the performance of the balance is mounted. Thus, it is possible to easily change only the design of the first housing 10 and the second housing 30 or only the performance of the scale by the functional component 20. For example, when it is desired to change the design, the reference base 29 on which the functional component 20 is mounted is used as it is, and the first casing 10 and the second casing 30 are formed into a cylindrical first casing having an upper surface. And it can change to the cylindrical 2nd housing | casing which has a lower surface.
