Abstract
Concave marks indicative of an orientation of a circuit board are formed on the circuit board, convex indices to be engaged with the marks are formed in a position in which the circuit is to be attached. An operator confirms the orientation of the circuit board easily and accurately by visually recognizing the marks and touching the marks with a finger. Moreover, the operator positions the circuit board by engaging the marks with the indices.
