摘要： A video recording and reproducing unit of the helical scan type having a slow speed tape running mode is provided. This unit has a pair of azimuth heads (20,21) of mutually different angles which are mutually adjacently disposed on the outer periphery of a rotating cylinder (19) and another pair of azimuth heads (22,23) of mutually different angles which are mutually adjacently disposed at positions symmetrical to the first pair of azimuth heads (20,21) with respect to the rotation axis. Each of the two pairs alternately traces the tracks on a magnetic tape (18) to reproduce the recorded video signals. Further, the unit has a control head (24) for reproducing a control signal (CTL) which is synchronous with a header position of the recorded tracks, a traced azimuth predicting signal generating unit (8) for generating a predetermined azimuth change over signal (AZP) in response to the control signal (CTL), and a switching unit (13,4) for selecting one of the reproduced image signals from the pair of azimuth heads according to the change over signal (AZP) in the slow speed running mode. Further, the present recorder has units (32d,32e) for comparing envelope levels of reproduced image signals from each pair of the heads to detect the head of the larger envelope, and switching units (32b,32c) for holding the selection of the signal with the larger envelope level while a pair of the heads is scanning the tracks until the tracing by this pair of heads is replaced by the tracing by the other pair of heads during the slow speed running mode.

In response to information supplied from the plant and a manipulating signal of the manipulating device, a first display data producing device (8A - 8G) produces first display data needed for the operation of the plant changing every moment. On the basis of data supplied from the first display data producing device (8A - 8G), a first display device (2) displays information relating to the operation of the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device (3), a second display data producing device (7A, 7B) produces data needed for monitoring the plant. On the basis of data supplied from the second display data producing device (7A, 7B) a second display device (4) displays information relating to the monitoring of the plant on a larger display screen (4A, 4B) than that of the first display device (2).
