Abstract

PURPOSE:To discriminate automatically whether a control peripheral part and input and output devices are connected or not and switch automatically functions of a control center part, by providing preliminarily switches in input and output devices and providing control discriminating parts and signal presence/absence discriminating parts in them. CONSTITUTION:Input devices 11 and 12 and output devices 13 and 14 are connected to a control peripheral part 3' through a cable 15 and a connector 16 and are provided with switches S1-S4 preliminarily. The peripheral part 3' is provided with plural parts A1-An taking charge of functions in accordance with connectable input and output devices, and parts A1-An are provided with connection discriminating parts and signal presence/absence discriminating parts which output a control signal to a control center part 2' when input and output devices are connected to a control part 1'. This signal presence/absence discriminating part does not output the control signal when a high-level signal is given from the connection discriminating part, but the signal presence/absence discriminating part outputs the control signal to the center part 2' when a low-level signal is given. Thus, functions of the control center part are switched and operated automatically in accordance with connected input and output devices.

A signal presence/absence determining section 0 (to) is provided which outputs a control signal to the control center section (2) when connected to the control center section (2). Each of the connection determination units a7) has a series circuit of a first resistor wire and a capacitor (a) to which AC power is supplied from one end and is grounded at the other end, and a signal presence/absence determination unit between the midpoint of this series circuit. 08) and a connector 06) to which the middle point and the ground side of the capacitor (A) are connected.
It is composed of. Also, when a high level signal is given from the signal presence/absence discriminating section QgJ & connection discriminating section a7), the control signal is not outputted, and when a low level signal is given, the control section ( 1)
It is provided with common software including programs for a plurality of models corresponding to each of the input and output image devices that can be connected to the computer. Furthermore, among the peripheral devices (7), (8), and (9), the display device (8) that controls the display function is configured so that all displays can be performed in accordance with connectable input and output image devices. There is.

Next, the operation of the above control device will be explained. First, the third
When the input device Ql) is not connected to the control peripheral section (3), the first,
A high level signal is given through the second resistor (21), and a control signal corresponding to the control center (output 01 to 21) is not output, but is provided in the display device (8). The display portion corresponding to the third input device Ql) is not displayed, and the portion corresponding to the control center (third input device 01 among the plurality of functions of 21) is not used. Next, when the third input device 01) is connected to the connection determination unit αη of the control unit (1) via the cable (15) and the connector α6) (+6), the capacitor (20)
is short-circuited by the switch (Sυ), and the connection determination part a'?
) gives a low level signal to the signal presence/absence discriminator 08, which outputs a control signal to the control center (2). Based on this control signal, the function corresponding to the third input device α1) of the control center (2) starts operating, and for example, the third input device α]) is in charge of temperature input, When the temperature data obtained is an abnormal temperature, a lighting signal is given to the display device (8) in the peripheral device via the control peripheral section (3), and the display section corresponding to the third input device 01) lights up. The abnormal temperature is displayed.
