In a stencil printer, an elastic member is provided on a master conveying path from a roll of master sheet to a master pinch drum. The elastic member is pressed against the master sheet to apply back tension to the master sheet when the master sheet is moved by rotation of the master pinch drum after the leading end of the master sheet has been clamped to the clamp portion of the master pinch drum.

A machining device equipped with a spindle position interchanger comprises a longitudinal table provided on a bed and movable in a horizontal direction; a transverse table provided on the longitudinal table and movable in a direction perpendicular to the longitudinal table; a column erected on the transverse table and turnable in a horizontal plane; a first spindle head vertically movable along the column; a second spindle head provided at a position different from (at a position at 1800° to, or opposite to) the position of the first spindle head and vertically movable along the column independently of the first spindle head; a first main spindle and a second main spindle attached to the first spindle head and the second spindle head, respectively; a tool change arm for changing a tool in the second main spindle; and a tool magazine mounted on an upper portion of the column for housing many tools. This machining device, and a method for interchanging spindle positions in the machining device obviate the need for the time for tool change done while stopping the rotation of the main spindle.
