A structure and method for making a structure for use in building construction is provided. The printed circuit includes a communication control unit disposed between the transmission bus and the connection element, the communication control unit includes unidirectional communication logic gates, and a logic control circuit for the logic gates. The processing time is reduced in comparison to that required by other methods for generating measures of quality. A second command writes data to the extension register in units of given data lengths. In this manner, when the process for a simple error with respect to the generated motor error is executed, the user may perform, for example, removal of the paper that is the cause of the paper jam or the like before the movement process is executed by the button operation.
