　図１に示すように、電動工具システムＳは、電動工具１０と操作プレート４０とを備える。操作プレート４０は、外部機器及び電動工具用操作機として設けられる。 Hereinafter, an embodiment of a power tool system will be described with reference to the drawings.
As shown in FIG. 1, the power tool system S includes a power tool 10 and an operation plate 40. The operation plate 40 is provided as an operating device for external devices and electric tools.

The battery pack 12 includes a plurality of battery cells 12a as shown in FIG.
　電動工具本体１１の外郭をなすハウジング１３は、略円筒状の本体部１４と、この本体部１４の長手方向途中から下方に延びた把持部１５と、把持部１５の下端に位置して電池パック１２を装着するための電池パック装着部１６とを有している。 A housing 13 that forms an outline of the electric power tool main body 11 includes a substantially cylindrical main body portion 14, a grip portion 15 that extends downward from the middle of the main body portion 14 in the longitudinal direction, and a battery pack that is positioned at the lower end of the grip portion 15 And a battery pack mounting portion 16 for mounting 12.
　本体部１４の内部には、モータ１７と、モータ１７のモータ軸１７ａと連結される駆動伝達部１８（駆動部）が配置されている。駆動伝達部１８は、モータ１７の回転駆動力を駆動伝達部１８の前方に配置された出力軸（図示略）に伝達するものであり、例えば減速機構及びクラッチ機構等を含む。 In the main body 14, a motor 17 and a drive transmission unit 18 (drive unit) connected to the motor shaft 17a of the motor 17 are arranged.

　第１操作プレート４０ａは、主に穴あけ用に用いられるものであって、例えば、本実施形態では、先端工具装着部１９に装着された先端工具を高トルク・低速で略一定速で回転駆動させるために用いられる。第１操作プレート４０ａのメモリ４５には、３００ｒｐｍ（回転数／分）で電動工具１０を動作させるモード情報と、２００ｒｐｍで電動工具１０を動作させるモード情報と、１００ｒｐｍで電動工具１０を動作させるモード情報が記憶されている。これら３種類のモード情報は、第１操作プレート４０ａに設けられたモード切替スイッチ４２の操作によって切り替えることができる。 The first operation plate 40a is mainly used for drilling. For example, in the present embodiment, the tip tool mounted on the tip tool mounting portion 19 is rotationally driven at a substantially constant speed with high torque and low speed. Used for. In the memory 45 of the first operation plate 40a, mode information for operating the electric tool 10 at 300 rpm (number of revolutions / minute), mode information for operating the electric tool 10 at 200 rpm, and a mode for operating the electric tool 10 at 100 rpm Information is stored. These three types of mode information can be switched by operating a mode switch 42 provided on the first operation plate 40a.
　第２操作プレート４０ｂは、ネジ締めや穴あけ用に用いられるものであって、例えば、本実施形態では、第１操作プレート４０ａに記憶されているモード情報よりも低トルク・高速で回転駆動させるために用いられる。第２操作プレート４０ｂのメモリ４５には、小ねじを締める際に用いるモード情報と、比較的大径の穴あけ作業時に低トルク・高回転で先端工具を回転駆動させるためのモード情報と、比較的小径の穴あけ作業時に高トルク・低回転で先端工具を回転駆動させるためのモード情報とが記憶されている。これら３種類のモード情報は、第２操作プレート４０ｂに設けられたモード切替スイッチ４２の操作によって切り替えることができる。 The second operation plate 40b is used for screw tightening and drilling. For example, in the present embodiment, the second operation plate 40b is driven to rotate at a lower torque and higher speed than the mode information stored in the first operation plate 40a. Used for. In the memory 45 of the second operation plate 40b, mode information used when tightening the machine screw, mode information for rotating the tip tool with low torque and high rotation during drilling of a relatively large diameter, and relatively Mode information for driving the tip tool to rotate with high torque and low rotation at the time of drilling a small diameter is stored. These three types of mode information can be switched by operating a mode changeover switch 42 provided on the second operation plate 40b.
　第３操作プレート４０ｃでは、制御部４４が、メモリ４５への新たなモード情報の追加や、メモリ４５からの記憶済みモード情報の削除を制御することが可能である。即ち、第３操作プレート４０ｃでは、メモリ４５におけるモード情報の書き換えが可能となっている。このため、例えば使用者が好みのモード情報をモード情報提供サーバー上からダウンロードし、そのダウンロードしたモード情報を第３操作プレート４０ｃのプレート側通信部４１を介してメモリ４５に追加することができる。これによって、使用者の好みのモード情報を利用することが可能となっている。 In the third operation plate 40 c, the control unit 44 can control addition of new mode information to the memory 45 and deletion of stored mode information from the memory 45. That is, the mode information in the memory 45 can be rewritten on the third operation plate 40c. For this reason, for example, the user can download desired mode information from the mode information providing server, and the downloaded mode information can be added to the memory 45 via the plate side communication unit 41 of the third operation plate 40c. This makes it possible to use user's favorite mode information.
　次に、本実施形態の電動工具１０の動作例を説明する。
　本実施形態の電動工具１０は、操作プレート４０ａ～４０ｃのうちいずれかが装着された状態で、その装着された操作プレート４０で選択されたモード情報に応じて動作するようになっている。例えば、使用者が電動工具１０に装着された操作プレート４０のモード切替スイッチ４２を操作すると、制御部４４は、使用者の操作によって選択されたモード情報を操作プレート４０のメモリ４５から読み取り、読み取ったモード情報をプレート側通信部４１を介して外部（電動工具１０）に送信する。送信されたモード情報は電動工具本体１１の本体側通信部２６を介してマイコン２５で受信される。マイコン２５は、受信したモード情報に基づいて、スイッチング素子駆動回路２９を介してモータ１７の駆動を制御する。 Next, an operation example of the power tool 10 of the present embodiment will be described.
The electric power tool 10 of the present embodiment is configured to operate in accordance with mode information selected by the attached operation plate 40 in a state where any of the operation plates 40a to 40c is attached. For example, when the user operates the mode changeover switch 42 of the operation plate 40 attached to the electric tool 10, the control unit 44 reads the mode information selected by the user's operation from the memory 45 of the operation plate 40 and reads it. The mode information is transmitted to the outside (power tool 10) through the plate side communication unit 41. The transmitted mode information is received by the microcomputer 25 via the main body side communication unit 26 of the electric power tool main body 11. The microcomputer 25 controls the driving of the motor 17 via the switching element driving circuit 29 based on the received mode information.
　本実施形態の電動工具１０は、例えば操作プレート４０を取り外した状態であっても、デフォルトモードで動作する。デフォルトモードは電動工具の仕様によって異なる。その一例としては、使用者がトリガスイッチ２０を引き込むと、電動工具１０はトリガスイッチ２０の引き込み量に応じて先端工具の回転数（つまり、モータ１７の回転速度）を変化させるように動作する。 The power tool 10 of the present embodiment operates in the default mode even when the operation plate 40 is removed, for example. The default mode depends on the specifications of the power tool. As an example, when the user pulls in the trigger switch 20, the electric tool 10 operates to change the rotation speed of the tip tool (that is, the rotation speed of the motor 17) according to the pull-in amount of the trigger switch 20.
　次に、本実施形態の効果を記載する。
　（１）電動工具１０は、外部機器（電動工具用操作機）である操作プレート４０と通信可能な本体側通信部２６を有する。この本体側通信部２６は、操作プレート４０との通信を介して、マイコン２５によるモータ１７の駆動制御を決めるためのモード情報を受信する。マイコン２５は、本体側通信部２６から供給されるモード情報に基づいてモータ１７の駆動制御を行う。これにより、通信対象である操作プレート４０を交換することでモード情報を変更することが可能となるため、電動工具１０自体を交換しなくても作業内容を容易に変更することが可能となる。 Next, the effect of this embodiment will be described.

The main body side communication unit 26 receives mode information for determining drive control of the motor 17 by the microcomputer 25 through communication with the operation plate 40. The microcomputer 25 controls the drive of the motor 17 based on the mode information supplied from the main body side communication unit 26. Thereby, since it becomes possible to change mode information by exchanging the operation plate 40 which is a communication object, it becomes possible to easily change the work contents without exchanging the electric tool 10 itself.
　（２）モータ１７は、ブラシレスモータであるため、ブラシ付モータのようなブラシの摩耗が無いため長寿命化を図ることができる。
　（３）操作プレート４０は、電動工具１０と通信可能なプレート側通信部４１と、電動工具１０内のモータ１７の駆動制御を決めるためのモード情報を記憶するメモリ４５とを有する。プレート側通信部４１は、メモリ４５に記憶されたモード情報を、プレート側通信部４１を介して電動工具１０に送信する。これによって操作プレート４０を交換することでモード情報を変更することが可能となるため、電動工具１０自体を交換しなくても作業内容を容易に変更することが可能となる。 (2) Since the motor 17 is a brushless motor, there is no brush wear unlike a motor with a brush, so that the life can be extended.
(3) The operation plate 40 includes a plate-side communication unit 41 that can communicate with the electric power tool 10 and a memory 45 that stores mode information for determining drive control of the motor 17 in the electric power tool 10. The plate side communication unit 41 transmits the mode information stored in the memory 45 to the power tool 10 via the plate side communication unit 41. As a result, the mode information can be changed by exchanging the operation plate 40, so that the work content can be easily changed without exchanging the electric tool 10 itself.
　（４）メモリ４５は、複数種類のモード情報を記憶する。操作プレート４０は、メモリ４５に記憶された複数種類のモード情報のうちの一つを使用者によって選択可能なモード切替スイッチ４２と、使用者の操作によって選択されたモード情報を報知するモード表示部４３とを有する。これによって、操作プレート４０のモード切替スイッチ４２によって電動工具１０の動作を変更することができ、動作のバリエーションを増やすことができる。また、モード表示部４３によって現在のモード情報（電動工具１０の動作モード）を使用者に報知することができる。 (4) The memory 45 stores a plurality of types of mode information. The operation plate 40 includes a mode changeover switch 42 that allows the user to select one of a plurality of types of mode information stored in the memory 45, and a mode display unit that informs the mode information selected by the user's operation. 43. Thereby, the operation of the electric tool 10 can be changed by the mode changeover switch 42 of the operation plate 40, and the variation of the operation can be increased. Further, the mode display unit 43 can notify the user of the current mode information (the operation mode of the power tool 10).
　（５）メモリ４５は、モード情報の追加及び削除が可能に構成される。これによって使用者の好みのモード情報を設定することができる。
　（６）電動工具１０の本体側通信部２６と、操作プレート４０のプレート側通信部４１とは無線通信によって通信を行う。これによって、電動工具１０の防塵性や防水性を向上させることができる。 (5) The memory 45 is configured to be able to add and delete mode information. Thus, the user's favorite mode information can be set.
(6) The main body side communication unit 26 of the electric power tool 10 and the plate side communication unit 41 of the operation plate 40 communicate by wireless communication. Thereby, the dustproof property and waterproofness of the electric tool 10 can be improved.
　なお、上記実施形態は、以下のように変更してもよい。

In the above embodiment, the communication between the electric power tool 10 and the operation plate 40 is performed by wireless communication instead of direct electrical connection using a wired connection, but is not limited thereto. For example, the following configuration may be adopted.
　図５及び図６に示すように、電動工具１０は、電動工具本体１１の電池パック装着部１６の前方位置に設けられた操作機取付部としてのスロットＳＬを備える。スロットＳＬには操作プレート４０の一部が挿通可能となっている。このスロットＳＬは、接点Ｃ１（第１接点部）を含む。そして、操作プレート４０がスロットＳＬに機械的に取り付けられると、操作プレート４０に設けられた接点Ｃ２（第２接点部）がスロットＳＬの接点Ｃ１に直接接触して電気的に接続される。この構成では、操作プレート４０のプレート側通信部４１は、接点Ｃ１，Ｃ２を介して、電動工具１０の本体側通信部２６と通信を行う。ここで、操作プレート４０がスロットＳＬに取り付けられた状態においては、接点Ｃ１，Ｃ２がスロットＳＬによって隠蔽される。これによって防水性や防塵性を高めることが可能となる。なお、スロットＳＬの開口部ＳＬ１の内周面にパッキンを設け、スロットＳＬに挿通された操作プレート４０をパッキンにより軽圧で固定してもよい。これにより、更に防水性や防塵性を高めることができる。 As shown in FIGS. 5 and 6, the electric power tool 10 includes a slot SL as an operating unit mounting portion provided at a position in front of the battery pack mounting portion 16 of the electric power tool main body 11. A part of the operation plate 40 can be inserted into the slot SL. The slot SL includes a contact C1 (first contact portion). When the operation plate 40 is mechanically attached to the slot SL, the contact C2 (second contact portion) provided on the operation plate 40 is in direct contact with and electrically connected to the contact C1 of the slot SL. In this configuration, the plate side communication unit 41 of the operation plate 40 communicates with the main body side communication unit 26 of the electric power tool 10 via the contacts C1 and C2. Here, in a state where the operation plate 40 is attached to the slot SL, the contacts C1 and C2 are concealed by the slot SL. This makes it possible to improve waterproofness and dustproofness. Note that a packing may be provided on the inner peripheral surface of the opening SL1 of the slot SL, and the operation plate 40 inserted through the slot SL may be fixed with light pressure by the packing. Thereby, waterproofness and dustproofness can be improved further.

In the above-described embodiment, the operation plate 40 is configured to operate as the default mode in a state where the operation plate 40 is not attached to the power tool 10 (power tool main body 11), but is not limited thereto. For example, in a state where the operation plate 40 is not attached to the power tool 10, a configuration in which the operation of the power tool 10 is stopped may be employed. At this time, a configuration that notifies the user that the operation plate 40 is not attached by vibration, sound, display, or the like may be employed.

For example, a configuration in which a dedicated application program is introduced (for example, downloaded) to a mobile terminal that is easy for the user to wear such as a smartphone or a tablet terminal that can communicate with the power tool 10 may be employed. In this case, the portable terminal described above functions as a power tool operating device. Furthermore, these portable terminals do not need to be attached to the electric tool 10.
