中・し・を遇るほぼ同一・直線上としたものである。Problems to be Solved by the Invention In the conventional moderating encoder described above, the moderating plate 7 having the moderating groove 7a and the circular comb-shaped contacts 8.9 for pulses are placed on the substrate 4 in the same positional relationship. A rotary insulating plate 2, which is set so that the and moderation spring contact Sa are in the same positional relationship, is sliding due to the rotation of the operating shaft 1, but if the centers of these two plates are eccentric, then Initially, even if the brush contact portion and the circular comb-shaped contacts are in parallel contact, when the rotary insulating plate 2 is rotated, for example, about 90 degrees, the brush contact portion and the circular comb-shaped contacts 8 and 9 are in contact with each other at an angle α. As described above, each time the rotation angle of the rotary insulating plate 2 changes, the angle formed between the contact portion of the brush 3 and the circular comb-shaped contacts 8 and 9 changes, and the positional relationship also changes. It is important to eliminate variations in the signal and moderation when the operation shaft rotates, and to ensure that the connection between the terminals 13b and 14b is electrical when the moderation spring contact 5a is fitted into the groove 7a for the node 5, that is, when the operation shaft is stable. The present invention has a problem in that it is not possible to guarantee an insulated state in a rotary moderating encoder. The generation part and the moderation groove provided for each single pulse during rotation operation are used as contact plates on the operating shaft, and the positions of the moderation spring contacts and the pair of brush contacts on the pulse signal layer are The operating axes of all related brush holders are placed almost on the same line, facing each other during rotation.
