Description
本発明は、基板組立体及び画像形成装置に係り、特に機能に応じた必要最小限のコストで増設基板を設けることができる基板組立体及び画像形成装置に関する。 The present invention relates to a substrate assembly and an image forming apparatus, and more particularly to a substrate assembly and an image forming apparatus in which an additional substrate can be provided at a necessary minimum cost according to the function.
プリンタ等の画像形成装置においては、オプションとしてネットワーク基板やファックス基板を増設することができるものがある。このような画像形成装置では、図３（ａ）に示すように、制御部３０は各機能部を制御するプリント基板を組みたてて作成する。本例では、各機能部を制御する基板として、制御基板３１、画像処理基板３２を有する。この制御基板及び画像処理基板を設けることにより、画像形成装置は、基本的な機能を具備することとなる。 Some image forming apparatuses such as printers can have an additional network board or fax board as an option. In such an image forming apparatus, as shown in FIG. 3A, the control unit 30 assembles and creates a printed circuit board that controls each functional unit. In this example, a control board 31 and an image processing board 32 are provided as boards for controlling each functional unit. By providing the control substrate and the image processing substrate, the image forming apparatus has basic functions.
また、上記基本的機能に加えてネットワーク接続、ファックス通信を行える用にするためには、上記構成に加えてファックス基板３４やネットワーク基板３５を上記２つの基板３１，３２に接続する必要がある。 In addition to the above basic functions, in order to be able to perform network connection and fax communication, it is necessary to connect the fax board 34 and the network board 35 to the two boards 31 and 32 in addition to the above configuration.
そのため、前記制御基板３１と画像処理基板３２とを組みたてる際増設基板であるマザーボード３３を前記制御基板３１、画像処理基板３２に対して略垂直に立設し、このマザーボード３３に前記ファックス基板３４やネットワーク基板３５を取り付けるようにしている。 Therefore, when assembling the control board 31 and the image processing board 32, a mother board 33 as an additional board is erected substantially perpendicular to the control board 31 and the image processing board 32, and the facsimile board is mounted on the mother board 33. 34 and the network board 35 are attached.
ここで、図３（ａ）に示すように制御基板３１にはコネクタ４１、画像処理基板３２にはコネクタ４２、マザーボード３３にはコネクタ４３，５４，４５，４６が設けられており、制御基板３１と画像処理基板３２とは、コネクタ４１をコネクタ４３に接続し、コネクタ４２をコネクタ４３に接続することにより、物理的電気的に接続するようにしていた。 Here, as shown in FIG. 3A, the control board 31 is provided with a connector 41, the image processing board 32 is provided with a connector 42, and the mother board 33 is provided with connectors 43, 54, 45, 46. The image processing board 32 is physically and electrically connected by connecting the connector 41 to the connector 43 and connecting the connector 42 to the connector 43.
そしてこの状態では、図３（ｃ）に示すようにマザーボード３３は制御基板３１、画像処理基板３２に対して略垂直に立設された状態となりファックス基板３４のコネクタ４７をマザーボード３３のコネクタ４５に、ネットワーク基板３５のコネクタ４８をマザーボード３３のコネクタ４６に接続するようにして、マザーボード３３にファックス基板３４及びネットワーク基板３５を接続するものとしている。 In this state, as shown in FIG. 3C, the mother board 33 is erected substantially perpendicular to the control board 31 and the image processing board 32, and the connector 47 of the fax board 34 is connected to the connector 45 of the mother board 33. The fax board 34 and the network board 35 are connected to the motherboard 33 by connecting the connector 48 of the network board 35 to the connector 46 of the motherboard 33.
この状態において、制御部３０Ａは、基本的機能と、ネットワーク機能と、ファックス機能を備えることとなる。 In this state, the control unit 30A has a basic function, a network function, and a fax function.
このような従来の画像形成装置においては、ファックス機能やネットワーク機能を必要としない基本的な構成の制御部３０Ｂを備えた画像形成装置であっても制御基板３１と画像処理基板３２とを電気的に接続するためにマザーボード３３を組み付ける必要があり、コストが嵩む。一方、製造コストを低減するためマザーボード３３を介さずに制御基板３１と画像処理基板３２とを接続できるようにすると、マザーボード３３の有無により両基板の接続関係が異ってしまうため、それぞれの条件においてＥＭＩ評価を行わなければならず、開発工数が増大してしまう。
In such a conventional image forming apparatus, the control board 31 and the image processing board 32 are electrically connected even if the image forming apparatus includes the control unit 30B having a basic configuration that does not require a fax function or a network function. It is necessary to assemble the mother board 33 in order to connect to the battery, increasing the cost. On the other hand, if the control board 31 and the image processing board 32 can be connected without going through the mother board 33 in order to reduce the manufacturing cost, the connection relationship between the two boards differs depending on the presence or absence of the mother board 33. In this case, EMI evaluation must be performed, which increases the development man-hours.
そこで本発明は、所定の機能を満たし低コストでかつＥＭＩ評価などの開発工数を低減することができる基板組立体及びこれを備えた画像形成装置を提供することを目的とする。 SUMMARY An advantage of some aspects of the invention is that it provides a substrate assembly that satisfies a predetermined function and can be manufactured at low cost and can reduce the number of development steps such as EMI evaluation, and an image forming apparatus including the substrate assembly.

以下本発明を実施するための最良の形態としての実施例を図面に基づいて説明する。 Embodiments as the best mode for carrying out the present invention will be described below with reference to the drawings.
図１は本発明に係る一実施例に係る画像形成装置の制御部を示す図である。本例の画像形成装置においては、オプションとしてネットワーク基板やファックス基板を増設することができる。制御部１０は各機能を制御するプリント基板を組みたてて作成する。本例では、各機能部を制御する基板として、制御基板１１、画像処理基板１２を備える。この制御基板１１及び画像処理基板１２を設けることにより、画像形成装置は、基本的な機能を具備することとなる。制御基板１１は基板ラック５５にネジ止め固定される。また、画像処理基板１２は基板ラック５５にスライドさせて１１と組み付けられ制御基板１１と接続され平板状の基板となる。本例では画像処理基板１２には、コントローラ６１，ハードディスクドライブ６２，増設のネットワーク基板６３が取り付けられている。なお、この例では、ネットワーク基板６３は画像処理基板１２に直接取り付けられる構成となっている。なお、図中５４は制御部１０を覆うカバーを示している。 FIG. 1 is a diagram illustrating a control unit of an image forming apparatus according to an embodiment of the present invention. In the image forming apparatus of this example, a network board or a fax board can be added as an option. The control unit 10 assembles and creates a printed circuit board that controls each function. In this example, a control board 11 and an image processing board 12 are provided as boards for controlling each functional unit. By providing the control substrate 11 and the image processing substrate 12, the image forming apparatus has a basic function. The control board 11 is fixed to the board rack 55 with screws. Further, the image processing board 12 is slid onto the board rack 55 and assembled with the board 11 and connected to the control board 11 to form a flat board. In this example, a controller 61, a hard disk drive 62, and an additional network board 63 are attached to the image processing board 12. In this example, the network board 63 is directly attached to the image processing board 12. In the figure, reference numeral 54 denotes a cover that covers the control unit 10.
本例では、図２（ａ）に示すように制御基板１１にはコネクタ２１が設けられ、また画像処理基板１２にはコネクタ２２が設けられ、これらのコネクタ２１，２２を接続することにより、制御基板１１及び画像処理基板１２は物理的、電気的に接続できる。この状態において、制御部１０Ｂは基本的な性能を備えることとなる。即ち、本例ではマザーボード１３（破線で示した）を使用することなく１０Ｂを構成できる。 In this example, as shown in FIG. 2A, a connector 21 is provided on the control board 11, and a connector 22 is provided on the image processing board 12. By connecting these connectors 21, 22, control is performed. The substrate 11 and the image processing substrate 12 can be physically and electrically connected. In this state, the control unit 10B has basic performance. That is, in this example, 10B can be configured without using the mother board 13 (shown by a broken line).
また、本例では、上記基本的機能に加えてネットワーク接続、ファックス通信を行える用にするためには、上記構成に加えてファックス基板１４ともう１つのネットワーク基板１５を２つの基板１１，１２に接続することができる。 In this example, in addition to the above basic functions, in order to enable network connection and fax communication, in addition to the above configuration, the fax board 14 and another network board 15 are connected to the two boards 11 and 12. Can be connected.
そのため、前記制御基板１１と画像処理基板１２とを組立て、平板状となった基板に増設基板であるマザーボード１３を前記制御基板１１、画像処理基板１２に対して略垂直に立設し、このマザーボード１３に前記ファックス基板１４、ネットワーク基板１５を取り付けるようにしている。また、この例では、ファックス基板３４には、ファックスのオプション基板５１，５２，５３が取り付けられている。 Therefore, the control board 11 and the image processing board 12 are assembled, and a mother board 13 as an additional board is erected substantially perpendicularly to the control board 11 and the image processing board 12 on the flat board. The fax board 14 and the network board 15 are attached to 13. In this example, fax option boards 51, 52, and 53 are attached to the fax board 34.
図２（ａ）に示すように制御基板１１には上記コネクタ２２のほかにコネクタ２１が設けられている。そして、マザーボード１３にはコネクタ２４，２５，２６が設けられている。そして、制御基板１１とマザーボード１３とは、コネクタ２４をコネクタ２１に接続し物理的電気的に接続する。 As shown in FIG. 2A, the control board 11 is provided with a connector 21 in addition to the connector 22. The motherboard 13 is provided with connectors 24, 25, and 26. And the control board 11 and the motherboard 13 connect the connector 24 to the connector 21 and connect physically and electrically.
そして、図２（ｃ）に示すようにマザーボード１３は制御基板１１、画像処理基板１２に対して略垂直に立設された状態となり、ファックス基板１４のコネクタ２７をマザーボード３３のコネクタ２６に接続しマザーボード１３にファックス基板１４を、ネットワーク基板１５のコネクタ２８をマザーボード１３のコネクタ２５に接続してマザーボード１３にネットワーク基板３５を接続する。これにより、制御部１０Ａには、基本的機能の他、ファックス機能及びネットワーク機能が付加された状態となる。 As shown in FIG. 2C, the mother board 13 is erected substantially perpendicular to the control board 11 and the image processing board 12, and the connector 27 of the fax board 14 is connected to the connector 26 of the mother board 33. The facsimile board 14 is connected to the motherboard 13, the connector 28 of the network board 15 is connected to the connector 25 of the motherboard 13, and the network board 35 is connected to the motherboard 13. Accordingly, the control unit 10A is in a state in which a fax function and a network function are added in addition to the basic function.
本例によれば、ファックス機能やネットワーク機能を必要としない基本的な構成の制御部３０Ｂを備えた画像形成装置であればマザーボードを組み付ける必要がなくなり、コストが嵩む。一方、マザーボードの有無により量基板の接続関係が異なることがなく、ＥＭＩ評価を同一条件で行うことができ、開発工数を少なくすることができる。 According to this example, if the image forming apparatus includes a control unit 30B having a basic configuration that does not require a fax function or a network function, it is not necessary to assemble a motherboard, resulting in an increase in cost. On the other hand, the connection relationship of the quantity substrates does not differ depending on the presence / absence of the mother board, the EMI evaluation can be performed under the same conditions, and the development man-hours can be reduced.
