宜機枠に揺動自在に支承した接触子と、この接触
子の用紙との係合による揺動を電気、光あるいは
磁気的に認識する検知手段とからなる搬送用紙の
検知装置において、上記接触子を、その先端部が
搬送経路に臨む常態位置を、自重で形成する垂下
片で構成するとともに、この接触子に常態位置で
はバネ力を付与せず、所定の揺動角以上で常態位
置方向へのバネ力を付与するスプリング手段を設
けたことを特徴とする搬送用紙検知装置。 A contact whose tip end faces the paper conveyance path and whose base end is swingably supported on the machine frame as appropriate, and the swinging caused by the engagement of this contact with the paper is recognized electrically, optically, or magnetically. In the detection device for conveyed paper, the contactor is constituted by a hanging piece whose normal position, with its tip end facing the conveyance path, is formed by its own weight, and the contactor is subjected to a spring force in the normal position. What is claimed is: 1. A paper conveyance detection device characterized in that it is provided with a spring means that applies a spring force in the direction of a normal position at a predetermined swing angle or more without applying a spring force.
