Abstract:
A yarn wrapping member 15 and a yarn winding drum 17 are rotated in opposite directions to wrap the yarn around the yarn winding drum 17 for storage. Accordingly, the yarn speed is the sum of the rotative speed of the yarn wrapping member 15 and the reverse rotative speed of the yarn winding drum 17.
Abstract:
A transported material transporting device including: a power transmission switching mechanism configured to switch the transmission of the power between the intermediate gear and the cam drive gear between a transmitted state and a blocked state; a detection lever provided in the reversing path and configured to detect the presence or absence of the material to be transported which enters the reversing path; and a blocked-state locking mechanism configured to lock the blocked state of the power transmission switching mechanism when the discharging roller is in the released state, wherein the locked state of the blocked-state locking mechanism is released and the power transmission switching mechanism is switched from the blocked state to the transmitted state upon detection of the position of the trailing end of the material to be transported entering the reversing path by the detection lever.

Abstract:
A sheet conveyance apparatus includes a sheet conveyance path, a sheet feeding member, a driving mechanism, a stopper, an interlocking portion, a cover member, and an evacuation mechanism. The stopper is configured to change a posture between a projection posture and an evacuation posture. The projection posture is configured to project into the sheet conveyance path so as to prevent the sheet to be loaded on a sheet loading portion from abutting on the sheet feeding member. The evacuation posture is configured to evacuate the stopper from the sheet conveyance path. The evacuation mechanism is configured to: change the stopper to have the evacuation posture, or to be in a posture changeable state where the stopper changes from the projection posture to the evacuation posture by application of external force, in conjunction with a change of the cover member from a closed state to the open state.
Abstract:
A printer includes a lower tray and an upper tray disposed above the lower tray. An optical sensor which detects the presence or absence of a sheet is disposed above the upper tray. The optical sensor is disposed in a roller support member which supports a feeding roller and serves as a swingable swing member. A distance between the optical sensor and the sheet is adjusted by swing of the roller support member according to the number of sheets.
