摘要： Detection means detects the change of an impedance occurring in a coil in response to irregularities on the surface of a movable portion, and outputs its detection signal. A speed judgement circuit receives the detection signal from the detection means, and continuously generates a high level output signal when the detection signal changes after a predetermined time interval. A level detection circuit receives the detection signal, and generates a high level output signal when the detection signal is above a predetermined level. An AND circuit receives the output signals from the speed judgement circuit and the level detection circuit, and generates the output signal of the AND calculation. A movable portion stop report is made on the basis of confirmation that the delay of the report of the stop of the movable portion is reduced and moreover, a coil is normally combined with the movable portion, and the confirmation that the movable portion has been monitored immediately before the stop of the movable portion.

摘要： A detection means 1 detects changes in impedance generated at a coil TC caused in response to indentations Py1 and Py2 and projections provided at the surface of a movable portion Rot to generate a detection signal thereof. A speed judgement circuit 2, to which the detection signal from the detection means is provided, continuously generates a high level output signal A2i when the detection signal e change interval becomes greater than a specific length of time. A level detection circuit 3, to which the detection signal e is provided, generates a high level output signal A1i when the detection signal e is at or above a specific level. An AND circuit 4, to which the output signal A2i from the speed judgement circuit 2 and the output signal A2i from the level detection circuit 3 are provided, generates an output signal Z resulting from AND calculation of the two output signals A1i and A2i. The delay in notification of movable portion stop is reduced and notification of movable portion stop is issued based upon verification that the coil TC is combined with the movable portion Rot in a normal manner and also verification that the movable portion Rot has been monitored until immediately before the stop of the movable portion Rot.

摘要： A detector (1) outputs a signal e1 corresponding to the operation of an object having an operation characteristic in which a transition from a first state to a second state occurs. A first state detection circuit (2) generates a first output signal SA corresponding to the first state on the basis of the signal e1 supplied thereto from the detector (1). A second state detection circuit (3) generates a second output signal SB corresponding to the second state on the basis of the signal supplied thereto from the detector (1). The second output signal SB is generated only when a transition occurs normally from the first state to the second state and during the period in which the first output signal SA is active. A state judgement circuit (4) generates a state judgement output signal Z under the condition that both of the first and second output signals SA and SB have a period in which they are simultaneously at a high level.

摘要： A detector (1), with its object of detection having operation characteristics that include a shift from a first state to a second state, outputs a signal (e1) that corresponds to the operation characteristics of the object of detection. A first state detection circuit (2) generates a first output signal (SA) corresponding to the first state based upon the signal (e1) provided by the detector (1). A second state detection circuit (3) generates a second output signal (SB) corresponding to the second state based upon the signal provided by the detector (1). The second output signal (SB) is generated only when the object of detection shifts from the first state to the second state in a normal manner while the first output signal (SA) is being generated. A state judgement circuit (4) generates a state judgement output signal (Z) on condition that there has been a period of time during which the first output signal (SA) and the second output signal (SB) have been both at high.
摘要翻译：检测器（1），其检测对象具有包括从第一状态到第二状态的移位的操作特性，输出与检测对象的操作特性对应的信号（e1）。第一状态检测电路（2）基于由检测器（1）提供的信号（e1）产生与第一状态相对应的第一输出信号（SA）。第二状态检测电路（3）根据由检测器（1）提供的信号产生与第二状态对应的第二输出信号（SB）。只有当检测对象在生成第一输出信号（SA）时以正常方式从第一状态转移到第二状态时，才产生第二输出信号（SB）。状态判断电路（4）在第一输出信号（SA）和第二输出信号（SB）都处于高电平的时间段的条件下产生状态判断输出信号（Z）。
