Abstract:
1. A printer apparatus comprising: a paper carrier plate portion for carrying paper on which an image is printed; a prescribed shaft portion arranged above said paper carrier plate portion; a paper feed roller for feeding the paper, provided on said shaft portion; a pushing member for pushing said paper carrier plate portion toward said paper feed roller; a cam provided on said shaft portion; and a cam abutment portion provided in said paper carrier plate portion and abutting on said cam; wherein an outer circumference of said cam includes a stepped portion having a first end and a second end, said first end pushing said paper carrier plate portion away from said paper feed roller against said pushing member when said stepped portion abuts on said cam abutment portion, said stepped portion disposed in a substantially radial direction of said cam, and said cam is formed from a resin and includes a cut-out portion in an area of said cam other than the stepped portion so that a portion of said cam abutting on said cam abutment portion when said paper carrier plate portion is pushed toward said paper feed roller is substantially more elastic than the stepped portion.
