| description | To provide a medium guide device capable of suppressing an occurrence of collision noise caused by bouncing up of a rear end of a medium while ensuring smooth conveyance of the medium on a curved path.SOLUTION: A medium guide device 35 includes: an upstream roller pair 42 and a downstream roller pair 43 provided in a curved path 6A; a first rib 44 protruding from/withdrawing to outside in a radial direction of the curved path 6A on an upstream side of an apex portion 6T; a second rib 45 protruding from/withdrawing to inside in the radial direction of the curved path 6A on a downstream side of the apex portion 6T; and an interlocking part 46 interlocking the first rib 44 with the second rib 45, wherein when paper P being conveyed by the upstream roller pair 42 is in a first conveyance state S1 where it is away from the downstream roller pair 43, the interlocking part 46 withdraws the first rib 44 and protrudes the second rib 45, and when the paper P is in a second conveyance state where the paper P is conveyed by the downstream roller pair 43, the interlocking part 46 protrudes the first rib 44 and withdraws the second rib 45.SELECTED DRAWING: Figure 3
【課題】湾曲経路において媒体の円滑な搬送を担保しながら媒体の後端の跳ね上がりに伴う衝突音の発生を抑制することができる媒体案内装置を提供する。【解決手段】媒体案内装置３５は、湾曲経路６Ａに設けられる上流側ローラー対４２および下流側ローラー対４３と、頂点部６Ｔよりも上流側で湾曲経路６Ａの径方向の外側から出没する第１リブ４４と、頂点部６Ｔよりも下流側で湾曲経路６Ａの径方向の内側から出没する第２リブ４５と、第１リブ４４と第２リブ４５とを連動させる連動部４６と、を備え、上流側ローラー対４２で搬送される用紙Ｐが下流側ローラー対４３から離れている第１搬送状態Ｓ１である場合、連動部４６は、第１リブ４４を退避させ、第２リブ４５を突出させ、用紙Ｐが下流側ローラー対４３で搬送される第２搬送状態である場合、連動部４６は、第１リブ４４を突出させ、第２リブ４５を退避させる。【選択図】図３ |
