特徴とするプリンタの用紙給紙機構。 A paper feed mechanism of a printer in which a feed roller that pulls out and feeds paper from a paper cassette is supported on a mounting bracket includes a bearing that rotatably supports the feed roller shaft on the feed roller shaft, a driven gear that rotates the feed roller shaft, and a bearing that rotatably supports the feed roller shaft. The mounting bracket is provided with a drive shaft parallel to the feed roller axis, and the drive shaft is provided with a drive gear that meshes with the driven gear and transmits rotation of the drive shaft to the feed roller. The feeding bracket is provided with a holding slit that opens in the direction of the extension line connecting the center point of the feed roller shaft and the drive shaft and holds the bearing of the feed roller unit in a detachable manner, so that the feed roller unit can be removed from the holding slit. A paper feed mechanism for a printer, characterized in that the paper feed mechanism for a printer is further provided with a lock lever that prevents the bearing from being pulled out from the holding slit when the bearing is held.
