Integrated recorder system which reads an instrumental signal from an input module so as to record instrumental data derived from the instrumental signal, and transmits the instrumental data recorded therein to an output module

An integrated recorder system comprising:

• a recorder main part having a control unit for recording instrumental data in a data memory, the control unit and the data memory being interconnected by a shared bus;
• a plurality of modules each of which is arbitrarily inserted in or withdrawn from the recorder main part regardless of whether the module is an instrumental data input device or an instrumental data output device, the plurality of modules including input modules and an output module, each input module having a connector terminal from which an instrumental signal is supplied, wherein, when the instrumental signal is an analog signal, the input module converts the analog signal into a digital signal indicating instrumental data, and supplies the digital signal to the recorder main part;
• and
• a data interface unit, provided in the recorder main part, having a plurality of bus-connection slots for connecting the plurality of modules inserted therein to the data interface unit, so that the plurality of modules, the data interface unit and the data memory are connected together by the bus, the data interface unit being controlled by the control unit through the bus to read the instrumental signal from one of the input modules when inserted in the recorder main part, such that the instrumental data is recorded in the data memory, and controlled by the control unit through the bus to transmit the instrumental data, recorded in the data memory, to the output module when inserted in the recorder main part.
