PURPOSE:To set a hard board at an accurate position on a print base by slowly rotating a registering member. CONSTITUTION:Front and lateral registering devices 6, 7 for registering a hard board laterally and forwardly are provided in a hard board printing machine for printing the board, such as a printed circuit board or the like. In the devices 6, 7, rotary members 17, 30 are rotated around an axis perpendicular to a print base 3 for supporting the board 2. Lateral and forward registering pins 21, 34 are eccentrically supported on the members 17, 30, respectively, and protruded from the base 3 to be movable to an operating position to be engaged with the side edge of the board 2 and a nonoperating position not to be protruded from the base. An air cylinder 19 for the pin corresponding to the width of the board 2 of the pins 21 is selected by a switch. After elevational air cylinders 19, 32 move the pins 21, 34 to the operating position, rotary air cylinders 34, 37 rotate the members 17, 30, respectively.
