发明名称 SPRING NOTES HAVE SPRING PERFORATED SPACER AND THE SPACER
摘要 The present invention relates to a spacer capable of facilitating note-taking on spiral bound notebooks. More specifically, the spiral bound notebooks include a spring perforated spacer to prevent a middle spring from being protruded when opening the notebooks and to be perforated through a spacer. When writing, the spring perforated spacer is configured to facilitate note-taking even a point where a spring is proximity. Therefore, the notebooks with the spring perforated spacer and the spacer have a structure to hold notes unless the spring connecting respective note pages is protruded over the surface of the notes when opening the spiral bound notebooks, wherein the spacer contains a protruded member which is perforated through the spring thereof to prevent separation.
