<p>PURPOSE:To record a picture in an emergency situation in case a timer is in a standby condition and to decrease the power consumption by releasing the timer standby condition by an alarm input, making an electric power source switch into an turning-on condition, and setting it to the picture recording condition. CONSTITUTION:By the alarm input from the external part, an alarm switch 19 comes to be the turning-on condition, then, a switch 22 comes to be the turning-off condition by the control voltage from the alarm switch 19, the supply of a timer standby signal (a) from a timer circuit 6 to a system control circuit 2 is stopped, and the timer standby condition is released. Simultaneously, since a picture recording switch 3 and an electric power source switch 9 come to be the turning-on condition, the picture-recording condition is obtained. Thus, even in the timer standby condition, the picture-recording at the time of emergency can be executed. At the time of the timer reservation, a timer signal (b) is sent from the timer circuit 6 to the system control circuit 2, and thus, the intermittent picture-recording can be executed.</p> |
