Summary:To suppress various problems produced when providing a double-feeding suppressing mechanism for two trays whose maximum accommodation numbers are different from each other.SOLUTION: A printer 1 has paper-feeding trays 10, 20, and separation members 71, 72 provided with respect to the paper-feeding trays 10, 20. The paper-feeding trays 10, 20 are movable in a front-rear direction D1 with respect to a housing of the printer 1, and can obtain an attachment position of being attached to the housing and a drawer position of being drawn forward from the housing. A length L2 in an oblique direction D3 of the separation member 72 is longer than a length L1 in the oblique direction D3 of the separation member 71. A stopper 92 is provided with respect to the paper-feeding tray 20. The stopper 92 is constituted so as to be able to obtain an advance position of advancing to a conveyance passage T, and a retreat position of retreating from the conveyance passage T, and moves to the retreat position from the advance position (advancing to the conveyance passage T) when the paper-feeding tray 20 moves to the attachment position from the drawer position. No stopper is provided with respect to the paper-feeding tray 10.SELECTED DRAWING: Figure 2 【課題】最大収容数が互いに異なる2つのトレイに対して重送抑制機構を設けた場合に生じ得る種々の問題を抑制する。【解決手段】プリンタ1は、給紙トレイ10,20と、給紙トレイ10,20に対して設けられた分離部材71,72とを有する。給紙トレイ10,20は、プリンタ1の筐体に対して前後方向D1に移動可能であり、筐体に装着される装着位置と、筐体から前方に引き出された引出位置とを取り得る。分離部材72の斜め方向D3の長さL2は分離部材71の斜め方向D3の長さL1よりも長い。給紙トレイ20に対してストッパ92が設けられている。ストッパ92は、搬送経路Tに進出する進出位置と、搬送経路Tから退避する退避位置とを取り得るように構成されており、給紙トレイ20が引出位置から装着位置へ移動するときに、進出位置(搬送経路Tに進出する)から退避位置に移動する。給紙トレイ10に対してストッパは設けられていない。【選択図】図2
