Title:
コイルユニット及びそれを備えたソレノイド
Document Type and Number:
Japanese Patent JP7040765
Kind Code:
B2
Abstract:
To provide a coil unit capable of preventing function lapse due to disconnection of a coil, without hindering compaction of an apparatus, and configured so that the sale price is hard to increase, and to provide a solenoid including the same.SOLUTION: Since an operation setting element group, consisting of bipolar transistors TR1-TR7, diodes D1-D7 and resistors R1-R7 is connected in parallel with streak layers L1-L7, the bipolar transistor corresponding to a disconnection part is turned on, when the streak layer is disconnected. Furthermore, phototransistors PTR1-PTR7 are turned on by light emission of light emission diodes LED1-LED7, and further turning the bipolar transistors TR1-TR7 on. Consequently, arbitrary one of the bipolar transistors TR1-TR7 can be turned on by operation of a selection switch SW.SELECTED DRAWING: Figure 2
