たは摺動部１に例えば磁気センサ、機械的スイッチ等の
検出器を配設して構成し、摺動子ｅが端子ａあるいは端
子Ｃ側に移動したことを検出することは容易である。In the figure, the left end detection section 22 and the right end detection section 4 are constructed by disposing a detector such as a magnetic sensor or a mechanical switch on the operating means d or the sliding section 1, and the slider e is connected to the terminal a or the terminal It is easy to detect that it has moved to the C side.
次に図を参照して作動を説明する。Next, the operation will be explained with reference to the drawings.
まず被検査可変抵抗器１の摺動子ｅを端子Ｃ側に配置す
るとともに第１記憶部３ぢよび第２記憶部６をリセット
し記憶を消去する。First, the slider e of the variable resistor 1 to be tested is placed on the terminal C side, and the first storage section 3 and the second storage section 6 are reset to erase their memories.
更に規定力発生部８の出力を基準値にセットする。Further, the output of the prescribed force generating section 8 is set to a reference value.
この時には端子ｂ ， ｃは短絡しているので右端検出
部４に出力信号が発生しているが、第１記憶部３はリセ
ットされ出力信号がないのでゲ゛一ト部５の出力に信号
が発生しない。At this time, terminals b and c are short-circuited, so an output signal is generated at the right end detection section 4, but the first storage section 3 is reset and there is no output signal, so a signal is generated at the output of the gate section 5. Does not occur.
しかる後駆動部７を左移動にセットし操作手段ｄを介し
て摺動子ｅを一定の力で左の方向に移動させる。Thereafter, the drive unit 7 is set to move to the left, and the slider e is moved to the left with a constant force via the operating means d.
摺動子ｅの先端が端子ａ，ｃの中間にある間、すなわち
端子ａ，ｔ）が短絡しない時には、左端検出部２の出力
に信号がないので第１記憶部３には記憶されない。While the tip of the slider e is between the terminals a and c, that is, when the terminals a and t) are not short-circuited, there is no signal in the output of the left end detection section 2, so it is not stored in the first storage section 3.
摺動子ｅが停止せず遂に左端に到達すると端子ａ，ｂが
短絡し、左端検出部２に出力信号が発生すると第１記憶
部３に記憶されゲート部５を開ける。When the slider e finally reaches the left end without stopping, the terminals a and b are short-circuited, and when an output signal is generated in the left end detection section 2, it is stored in the first storage section 3 and the gate section 5 is opened.
途中摺動子ｅが機械的精度あるいは糾立不良等により固
くなって停止した場合には左端検出部２の出力信号が発
生せず第１記憶部３に信号が記憶されない。If the slider e becomes hard and stops due to mechanical precision or poor tying, no output signal is generated from the left end detection section 2 and no signal is stored in the first storage section 3.
−ｉ時間経過後駆動部７を右移動に切換え摺動子ｅを端
子ａ側から端子Ｃ側に移動させる。- After the elapse of time, the drive unit 7 is switched to rightward movement and the slider e is moved from the terminal a side to the terminal C side.
右移動中には右端検出部４は出力信号を発生せず、更に
右に移動を続ければ遂に端子ｂ，ｃが短絡して移動を完
了する。While moving to the right, the right end detection section 4 does not generate an output signal, and if the movement continues further to the right, terminals b and c are finally short-circuited and the movement is completed.
この際左移動時、端子ａ，１）が短絡してから右移動に
なった場合にはゲート部５が開いているので端子ｂ，ｃ
が短絡すると同時に右端検出部４の出力に信号が発生し
第２記憶部６に記憶され端子ｆに信号が発生する。At this time, when moving to the left, if terminals a and 1) are short-circuited and then moving to the right, gate part 5 is open, so terminals b and c
At the same time as the short circuit occurs, a signal is generated at the output of the right end detection section 4, stored in the second storage section 6, and a signal is generated at the terminal f.
端子ｆに信号が発生した場合には摺動子ｅは左移動、右
移動とも正常に可変抵抗器１の回転トルクあるいは移動
操作力は規定内で良品である。When a signal is generated at the terminal f, the slider e moves normally to the left and right, and the rotational torque or movement operating force of the variable resistor 1 is within the specified range and is a good product.
信号が第１記憶部３に記憶され、第２記憶部６に記憶さ

械的精度の悪さ等の原因により停止したことを示し、第
１記憶部３、第２記憶部６に信号が記憶されていない場
合には左移動中に摺動子ｅが停止したことを示す。If the signal is stored in the first storage unit 3 but not in the second storage unit 6, this indicates that the slider e has stopped due to poor assembly, poor mechanical precision, etc. while moving to the right. , if the signal is not stored in the first storage section 3 or the second storage section 6, it indicates that the slider e has stopped while moving to the left.
以上説明したように本発明によれば規定力発生部、左右
