Claims

[Claims for Utility Model Registration] 1. Forming a desired pattern by engaging a contact with one cam selected from a group of pattern cams relating to a large number of predetermined patterns by rotating a pattern selection dial. In the sewing machine, a selection cam having a selection cam surface formed corresponding to each of the plurality of patterns for positioning the contact at a position facing a desired cam in the group of pattern cams; and a contact for the desired cam. a release cam having a smaller number of cam surfaces than the plurality of patterns and fixed to the pattern selection dial; and an engaging portion that elastically engages with the cam surface of the release cam. a release operating body that engages and disengages the contactor according to the cam surface thereof; a reduction gear mechanism that decelerates the operating rotation of the pattern selection dial and transmits it to the selection cam; and the pattern selection dial. a pattern display board rotatably disposed around the outer periphery of the sewing machine, on which shapes of the plurality of patterns are displayed; and a pattern display board rotatably arranged on the sewing machine frame to transmit the rotation of the selection cam to the pattern display board. a supported small gear; a first gear that rotates integrally with the selection cam and meshes with the small gear; a first gear having the same number of teeth as the first gear and fixed to the pattern display board; a gear mechanism including a second gear that meshes with a pinion; A multi-pattern sewing machine characterized by being engaged with the sewing machine. 2. The multi-pattern sewing machine according to claim 1, wherein the pattern display plate and the second gear are integrally molded from synthetic resin.
