Claims

[Scope of utility model registration request]

The rotating shaft, which is rotated at a constant speed by a gear train, has a plurality of bulging arc-shaped parts on the outer periphery.
Insert two main cams and two auxiliary cams in a superposed manner,
Moreover, the main cam is connected to the other main cam located at the next lower stage between the leading stage of one bulging arc-shaped part formed on the outer periphery and the leading stage of the next bulging arc-shaped part. Each main cam is arranged so that the leading step part of the section is located, and the auxiliary cams are arranged so as to correspond to the two upper main cams and the two lower main cams, respectively. On the other hand, of the two upper main cams and the two lower main cams, each of the two upper main cams has a leading step portion of one bulging arc-shaped portion of the lower main cam, and each of the upper main cams is located on the upper right side of the leading step portion. The cam group is configured such that one leading stage part of the auxiliary cam is located between the leading stage part of the auxiliary cam, and one contact piece is driven corresponding to each cam, so that the upper two main cams A time switch characterized in that a cam switch is constructed, each of which includes a contact piece that is driven by one auxiliary cam, and a pair of contact pieces that are driven by two lower main cams and another auxiliary cam. contact mechanism.
