摘要： A recording medium transporting device includes a transporting unit that transports a recording medium; a guide member that supports and guides the recording medium in a downstream direction, the guide member being disposed downstream of the transporting unit; and a restraining unit that includes a restraining member having a restraining section, the restraining section being movable relative to the guide member. The restraining section imposes a restraint on the recording medium to prevent the recording medium from rising above the guide member at a position downstream of the transporting unit. A restriction state of the restraining member is switchable between at least two states, and the restriction state is switched so that a degree of the restraint is reduced or the restraint is removed before a trailing edge of the recording medium passes the restraining section.

摘要翻译： 记录介质传送装置包括传送记录介质的传送单元; 引导构件，其在下游方向上支撑并引导记录介质，所述引导构件设置在所述传送单元的下游; 以及限制单元，其包括具有限制部的约束构件，所述限制部能够相对于所述引导构件移动。 限制部分对记录介质施加限制，以防止记录介质在传送单元下游的位置处在引导构件上方升高。 限制构件的限制状态可在至少两种状态之间切换，并且限制状态被切换，从而在记录介质的后缘通过约束部分之前减小约束程度或者去除限制。

摘要： A printing medium feeding device includes: a driving roller having a roller circumferential surface coming in contact with a printing medium to apply a feeding force to the printing medium around a core line of a rotation shaft and rotating to feeding the printing medium downstream; a driven roller in contact with the driving roller and following the rotation thereof; a shaft supporting member supporting the rotation shaft at least at two supporting positions; and a regulation unit regulating a core position of the rotation shaft between the two supporting positions at which the rotation shaft is supported by the shaft supporting member, wherein the regulation unit has a pressing surface coming in contact with the rotation shaft from the upstream side or the downstream side of the rotation shaft, and wherein the core position of the rotation shaft at the position of the regulation unit is located by the pressing surface to be more downstream than a straight line passing through the core positions of the rotation shaft at the two supporting positions when the pressing surface comes in contact with the rotation shaft from the upstream side, and the core position of the rotation shaft at the position of the regulation unit is located to be more upstream than the straight line when the pressing surface comes in contact with the rotation shaft from the downstream side.
