In the indexer of this type, since the bed and the presser foot of the sewing machine are present in the vicinity of the needle center position S, the guide G in the vicinity thereof is omitted.
Therefore, when the cloth to be sewn F is set so that the first button position or the first button hole position becomes the needle center position S by also helping to hide the edge of the cloth to be sewn F hidden by the presser foot. That is, it is difficult to align the position x, that is, the distance x in the sewing direction from the end of the cloth F to be sewn and the distance y from the virtual guide surface. Therefore, a sewing error occurs when the set cloth F to be sewn is sewn. This is particularly noticeable when the end of the cloth to be sewn F does not rest on the guide G at all.
