Claims

[Scope of claim for utility model registration] (1) A printed circuit board that has a base board on which multiple connectors are mounted at the back of a case that has an opening on one side, and that has various functions that can be removably fitted to the connectors. In a structure of a programmable controller in which a functional module consisting of a panel holding a printed circuit board is inserted into the case via the connector, the base can be freely rotated to a position corresponding to insertion of the printed circuit board in the case. When the lever is attached and the printed circuit board is inserted, the tip of the lever engages with the panel of the functional module, and the rotating action of the lever urges the holding part of the printed circuit board in the direction of removing the functional module. A structure of a programmable controller characterized in that a protruding piece is formed at the base of a lever. (2) A base board with multiple connectors mounted is placed in the back of a case with an opening on one side, a printed circuit board with various functions that can be removably fitted to the connectors, and a panel that holds this printed circuit board. In the structure of a programmable controller in which a functional module consisting of the above is inserted into the case via the connector, a lever with a rotatable base is attached to the case at a position corresponding to insertion of the printed circuit board, and the printed circuit board is inserted into the case. At the base of the lever is a protrusion that engages the tip of the lever with the panel of the functional module when the lever is inserted, and also forces the end of the printed circuit board in the direction of removing the functional module by the rotation of the lever. A structure of a programmable controller characterized by forming.
