Description
Claims (1)
- 記録媒体の搬送面をなし、前記記録媒体の搬送方向に沿って複数の吸引孔が穿設されたプラテンと、
前記吸引孔と連通する圧力室と、
前記圧力室に負圧を発生させるファンと、を備え、
前記圧力室は、仕切り壁により上圧力室と下圧力室に分割されており、前記仕切り壁の前記搬送方向の上流側の一部である上流側端部のみに前記上圧力室と前記下圧力室とを連通させる切り欠き部が形成され、
前記ファンは、前記下圧力室の開放部に取り付けられ、前記吸引孔から前記上圧力室、前記下圧力室を介して、吸気するようになっており、
前記上圧力室は、空気流の流線方向に一つの空間として形成され、
前記上圧力室の空気流の流線方向の断面積は、前記下圧力室の空気流の流線方向の断面積よりも小さくなるよう形成され、かつ前記切り欠き部の断面積は、前記上圧力室の空気流の流線方向の断面積よりも小さくなるように形成されており、
前記プラテン上を記録媒体が搬送される際、前記上圧力室における前記搬送方向の上流側を流れる空気の流量よりも前記上圧力室における前記搬送方向の下流側を流れる空気の流量を小さくして前記記録媒体を吸引しつつ搬送し、前記上圧力室の負圧を維持することができることを特徴とする媒体搬送装置。
