CONTROL DEVICE OF VIDEO RECORDING/REPRODUCING APPARATUS

摘要

WHEN OUTER POWER SOURCE (10) STOPS SUPPLYING POWER, CONTROLLER (107) BEING SET IN A FIRST POWER SAVING MODE BY MODE SETTER (106) RECEIVES A DETECTION-SIGNAL OF POWER FAILURE FROM DETECTOR (3). CONTROLLER (107) THEN STOPS OPERATING AN APPARATUS (12) AND ALSO STOPS POWERING AN ELECTRIC TIMER (4) TO HALT ITS COUNT-TIME OPERATION. CONTROLLER (107) STOPS AN OPERATION OF ITSELF BUT KEEPS POWERING DATA STORAGE DEVICE (105) TO RETAIN DATA. WHEN CONTROLLER (107) IS SET IN A SECOND POWER SAVING MODE, IT STOPS ONLY APPARATUS (12), AND KEEPS POWERING ELECTRIC TIMER (4) AND DATA STORAGE DEVICE (105) TO PRACTICE THE TIME-COUNT AND THE DATA RETENTION. CONTROLLER (107) ALSO POWERS ITSELF TO FUNCTION. THIS STRUCTURE ALLOWS A VIDEO RECORD/REPRODUCE APPARATUS TO SAVE POWER AND EXTEND A SERVICE LIFE OF BUILT-IN POWER SOURCE (11). (FIGURE 1)
