PURPOSE:To obtain an auto setting unit by which a sufficient electrical connecting state can be obtained without soldering by placing an armature block from the inside surface side of a printed board, engaging a part thereof to an engaging part of a unit baseplate and inserting and holding the printed board. CONSTITUTION:The title unit is provided with a unit baseplate 1, a flexible printed board 2 which is placed on the inside surface of the unit baseplate 1, prescribed detecting armatures 3b, 3c and 4b, and at least one armature block 3, 4 which has held those electric conduction armatures by insert forming in a holder part. The armature blocks 3, 4 are attached to the unit baseplate 1 by placing them from the inside surface side of the printed board 2 and engaging a part thereof to engaging parts 1a-1d of the unit baseplate 1. By attaching said armature blocks, the printed board 2 is inserted and held between the armature blocks 3, 4 and the unit baseplate 1, and these three are formed as a unit. By this attachment, the electric conduction armature is pressed against an exposed signal pattern of the printed board 2. |
