<P>PROBLEM TO BE SOLVED: To provide a highly reliable encoder capable of suppressing vibration of a printed board when the vibration and impact are received by a simple configuration. <P>SOLUTION: An encoder 10 has: a housing 12; an approximately discoid rotational code board 14 which is provided in the housing 12 and constituted so as to perform synchronous rotation with a rotation part of a body to be measured; and a printed board 16 which is attached to the housing 12 and arranged at an upper part of the code board 14, and further has a reinforcement member 20 with the shape so as to contact the printed board 16 at a part where displacement of the printed board 16 becomes large when the printed board 16 is resonated by vibration and impact, etc. added to the encoder. <P>COPYRIGHT: (C)2012,JPO&INPIT |
