摘要： In a device for recording an image while pulling back a recording sheet, a component of the device touches the slack portion of the recording sheet produced by pulling back thus causing a damage to the surface of the recording sheet. Such a device as having a brake means provided for a dancer roller and a recording sheet roll has a complicated mechanism and causes a variation in load in carrying the recording sheet to degrade a recording quality. A sheet feed roller pair for feeding the recording sheet to a carry roller pair is arranged between the carry roller pair for feeding or pulling back the held recording sheet fed out from a recording sheet roll and the recording sheet roll. A color recording section for forming a color image on the recording sheet while pulling back the recording sheet is arranged on the downstream side in the sheet feeding direction of the carry roller pair. A guide member for guiding the recording sheet in an almost arcuate shape so as to provide an included angle narrower than 90° is arranged between the sheet feed roller pair and the carry roller pair, and a retreat space for containing the slack of the recording sheet is arranged on the outside of the guide member wherein the guide member is pivotally supported to select by rotating opening or closing of the retreat space.
摘要翻译：在用于在拉回记录片材的同时记录图像的装置中，装置的部件接触通过拉回产生的记录片材的松弛部分，从而导致记录片材表面的损坏。这种具有为浮动辊和记录纸卷设置的制动装置的装置具有复杂的机构，并导致记录纸承载时的负载变化以降低记录质量。用于将记录纸张馈送到传送辊对的纸张馈送辊对布置在用于馈送或拉回从记录纸张辊馈送的保持的记录纸张和记录纸张辊之间的传送辊对之间。用于在记录纸张拉回的同时在记录纸张上形成彩色图像的彩色记录部分布置在运送辊对的纸张馈送方向的下游侧。在供纸辊对与输送辊对之间设置有用于引导记录纸张为大致弓形的引导部件，以提供窄于90°的夹角，并且用于容纳记录纸张的松弛的回退空间布置在引导构件的外侧，其中引导构件被枢转地支撑以通过旋转撤回空间的打开或关闭来进行选择。

摘要： In a printing device recording images on a recording paper being fed backward, bight portion of recording paper generated due to backward feeding contacts with machine components and generates scratches on the recording paper surface. A break unit may be provided on a dancer roller and a recording paper roller only with a complex mechanism and uneven conveying load resulting in a poor printing quality
The printing device is provided with a conveyer roller pair for holding therebetween a sheet paper drawn out from the recording paper roll to feed the sheet paper forward or backward, a feeding roller pair disposed between said recording paper roll and said conveyer roller pair for drawing out the recording paper and feeding it to the conveyer roller pair, a color recording unit disposed downstream of the conveyer roller pair in the direction of conveyance of the recording paper for recording a color image on the recording paper that is being moved backward, a guide unit is disposed between the feeding roller pair and the conveyer roller pair for bending and guiding the recording paper in an arc-shape at an acute angle smaller than 90 degrees, a reservation space is provided outside of the arc-shaped recording paper guiding path for accommodating the sagged recording paper therein, the guide unit has provided with a pivotally supported movable guide member, and that the guide unit is pivoted for selective opening or closing the holding member movable guide member.
