Abstract

The moving mechanism of a sheet feeding device has a first moving member and a second moving member. The first moving member is held in a position corresponding to the number of sheets supported by a sheet support member, and when moving in a specific direction can move the sheet support member in the separation direction away from a paper feed roller. The second moving member moves out and back through a specific range of movement in each revolution of the paper feed roller, engages the first moving member and moves the first moving member in the specific direction when moving out, and releases said engagement when moving back.

Description

technical field [0001] The present invention relates to a feeding device and a printer provided with a mechanism for keeping a sheet away from a feeding roller that feeds a sheet such as recording paper. Background technique [0002] As a sheet feeding device, for example, a paper feeding device of a printer is known. In the paper feeding device, the recording paper stacked and stored in the cassette is pressed against a paper feeding roller as a delivery roller. In this state, when the paper feed roller rotates, the recording paper is sequentially fed out to the paper feed path in the printer starting from the uppermost recording paper. For example, a sheet support member that supports recording paper in a stacked state in a cassette is called a feed plate. By pressing the feed plate toward the paper feed roller with the spring member, the stacked recording paper can be pressed against the paper feed roller regardless of the number of stored sheets. [0003] In the paper...
