<p><P>PROBLEM TO BE SOLVED: To provide a printer device with a paper mounting board whose impact is reduced to eliminate noises without an increase in production cost. <P>SOLUTION: The printer device comprises a paper feed roller 6 and a friction pad 5 arranged on the upper side of the paper mounting board 2 for mounting paper. The paper feed roller 6 is mounted on a predetermined shaft portion 4. A spring 8 is arranged on the lower side of the paper mounting board 2. A cam 10 including a stepped portion 10b is mounted on the shaft portion 4 for lifting the paper mounting board 2 using the energizing force of the spring 8 in response to the rotation of the paper feed roller 6. The paper mounting board 2 has a cam abutting portion 12 for abutting on the cam 10. The cam 10 is formed of e.g. a resin. The cam 10 has a predetermined lightening portion 10a for reducing the impact of the paper mounting board 2 when lifted after the cam 10 is rotated and released from the condition of abutting on the cam abutting portion 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
