　電動ドライバ等の電動工具において、電動工具の操作に関する情報を作業者に知らせるためのＬＥＤ等からなる発光表示部を備えたものがある。例えば特許文献１には、外付けされた操作情報表示器を備えた電動ドライバが開示されており、この電動ドライバにおいては、電動ドライバに内蔵された駆動制御回路や外部の制御回路からモータのＯＮ／ＯＦＦ状態や正転・逆転状態などの操作に関する情報を示す信号を受信したときにその信号に対応した発光形態で操作情報表示器のＬＥＤを発光させて、その情報を作業者に知らせるようになっている。 Some electric tools such as electric screwdrivers are equipped with a light emitting display unit consisting of LEDs or the like for informing the operator of information on the operation of the electric tool. For example, Patent Document 1 discloses an electric screwdriver provided with an external operation information display. In this electric screwdriver, the motor is turned on from a drive control circuit built in the electric screwdriver or an external control circuit. When a signal indicating information related to operations such as the / OFF state and the forward / reverse rotation state is received, the LED of the operation information display is made to emit light in a light emitting form corresponding to the signal so that the information is notified to the operator. It has become.
　また、ネジ締め下限時間、ネジ締め上限時間、回転速度、回転トルク、締め付け本数などの制御条件を設定するための設定データ（駆動設定パラメータ）をひとまとめにしたデータセット（パラメータ群）をメモリに複数記憶しておき、その中から任意のデータセットを選択して読み出すことにより必要な設定を一括で変更できるようにした電動ドライバもある（特許文献２）。この電動ドライバでは、データセットの読み出しと設定の変更は、ある決められた工程に従って自動的に順次行われるようにすることもできる。また、上述の電動ドライバに上記操作情報表示器のような発光表示部を設けて電動ドライバの操作に関する情報を表示できるようにしたものも開発されている。この電動ドライバにおいては、パーソナルコンピュータなどの外部装置から電動ドライバに信号を送信することにより、任意の発光形態で発光表示部を発光させることも可能となっている。 In addition, a plurality of data sets (parameter groups) that collect setting data (drive setting parameters) for setting control conditions such as screw tightening lower limit time, screw tightening upper limit time, rotation speed, rotation torque, and number of tightening lines are stored in the memory. There is also an electric driver that can be stored and the necessary settings can be changed at once by selecting and reading an arbitrary data set (Patent Document 2). With this electric screwdriver, it is also possible to automatically read data sets and change settings in sequence according to a predetermined process. Further, a light emitting display unit such as the operation information display is provided on the above-mentioned electric screwdriver so that information on the operation of the electric screwdriver can be displayed. In this electric screwdriver, it is also possible to make the light emitting display unit emit light in an arbitrary light emitting form by transmitting a signal from an external device such as a personal computer to the electric screwdriver.

The central control unit 50 includes an information display unit 16, a light emitting display unit 18, a motor control unit 48 for driving control of the electric motor 52, and a hall sensor for measuring the rotation speed (rotation speed) of the electric motor 52. 54 is connected. The central control unit 38 of the control device 12 and the central control unit 50 of the electric driver main body 10 are communicatively connected to each other via a cable 14.
　制御装置１２の設定変更操作部２６を操作して任意のＣＨ番号を選択すると、中央制御部３８は、選択されたＣＨ番号に対応したデータセットをメモリ３６から読み出す。そして中央制御部３８は、読み出したデータセットに含まれる各設定データをケーブル１４を介して電動ドライバ本体１０の中央制御部５０に送信する。電動ドライバ本体１０の中央制御部５０は、制御回路４０から設定データを受信すると、各設定データを電動ドライバ１の制御パラメータとして設定し、設定された制御パラメータに基づいて電動ドライバ本体１０の制御を行う。例えばＣＨ番号１が選択された場合には、電動モータ５２の回転数（回転速度）は６００ｒｐｍ（１／ｍｉｎ）、設定トルクは５Ｎｍとし、１つの工程におけるネジの締め付け本数は４本に設定される。また、発光表示部１８の発光色は赤に設定され、発光表示部１８のＬＥＤが赤色で点灯される。作業者は、発光表示部１８の赤色の発光を見ることによりその時に設定されているデータセットがＣＨ番号１に対応するものであることを容易に確認することができる。また、発光表示部１８はドライバビット２２の近くに配置されており、ネジ締め作業をする際に視界に入りやすい位置にあるため、その表示を確認し忘れることを防止できる。制御装置１２の中央制御部３８は、制御装置１２の全体的な制御を担うが、特に、複数のデータセットのうちの選択されたデータセットをメモリ３６から読み出して、選択されたデータセットに含まれる複数の設定データが電動ドライバ本体１０において当該電動ドライバ１の制御パラメータに設定されるようにするためのパラメータ設定部５６として機能する。 When an arbitrary CH number is selected by operating the setting change operation unit 26 of the control device 12, the central control unit 38 reads the data set corresponding to the selected CH number from the memory 36. Then, the central control unit 38 transmits each setting data included in the read data set to the central control unit 50 of the electric driver main body 10 via the cable 14. When the central control unit 50 of the electric driver main body 10 receives the setting data from the control circuit 40, each setting data is set as a control parameter of the electric driver 1, and the electric driver main body 10 is controlled based on the set control parameter. Do. For example, when CH number 1 is selected, the rotation speed (rotation speed) of the electric motor 52 is 600 rpm (1 / min), the set torque is 5 Nm, and the number of screws tightened in one process is set to 4. To. Further, the light emitting color of the light emitting display unit 18 is set to red, and the LED of the light emitting display unit 18 is lit in red. The operator can easily confirm that the data set set at that time corresponds to CH number 1 by observing the red light emission of the light emission display unit 18. Further, since the light emitting display unit 18 is arranged near the driver bit 22 and is in a position where it can be easily seen when the screw tightening operation is performed, it is possible to prevent forgetting to check the display. The central control unit 38 of the control device 12 is responsible for the overall control of the control device 12, and in particular, reads a selected data set from the plurality of data sets from the memory 36 and includes the selected data set in the selected data set. It functions as a parameter setting unit 56 for setting a plurality of setting data to be set in the control parameter of the electric driver 1 in the electric driver main body 10.
　各データセットの発光設定データには、図３に示すように、それぞれ異なる発光色を設定することができる。当該実施形態においては、赤、白、緑、青に加えて、黄、シアン、マゼンタを設定できるようになっているが、他の色を設定できるようにしてもよい。また、発光させない設定にすることもできる。発光設定データを含む各設定データは、制御装置１２の設定変更操作部２６を操作することにより作業者が任意に変更することができる。また、通信部４２に接続された他の制御装置１２等から設定変更コマンドを送信してメモリに記憶されている各設定データを変更することもできる。 As shown in FIG. 3, different emission colors can be set for the emission setting data of each data set. In the embodiment, yellow, cyan, and magenta can be set in addition to red, white, green, and blue, but other colors may be set. It is also possible to set not to emit light. Each setting data including the light emission setting data can be arbitrarily changed by the operator by operating the setting change operation unit 26 of the control device 12. It is also possible to change each setting data stored in the memory by transmitting a setting change command from another control device 12 or the like connected to the communication unit 42.
　このように当該電動ドライバ１においては、各ＣＨ番号に対応付けられたデータセットに発光表示部１８の発光色を設定するための発光設定データが含まれているため、パーソナルコンピュータなどの外部装置を使用することなく、選択されたデータセットに対応した発光色で発光表示部１８を点灯させることが可能となる。また、制御装置１２に設けられた設定変更操作部２６を操作することにより発光設定データを任意に変更可能となっているため、各ＣＨ番号を選択したときの発光表示部１８の発光色を作業者が容易に変更することが可能となる。 As described above, in the electric driver 1, since the data set associated with each CH number includes the light emission setting data for setting the light emission color of the light emission display unit 18, an external device such as a personal computer can be used. It is possible to light the light emitting display unit 18 with the light emitting color corresponding to the selected data set without using it. Further, since the light emission setting data can be arbitrarily changed by operating the setting change operation unit 26 provided in the control device 12, the light emission color of the light emission display unit 18 when each CH number is selected is worked. Can be easily changed by a person.
