IPC: H04N5/765
Filed: 1985-10-19
Abstract: PURPOSE:To prevent the shift of a recording timing by constituting such that photographing and recording controls are started after a drive means rotatably driving a rotating magnetic recording medium comes to rotate it normally. CONSTITUTION:When a release button 22 is operated to close a switch SW1, a drive signal from a servo circuit 50 starts a spindle motor 44 for driving the recording medium to rotate it. When the rotational frequency of the motor 44 reaches the prescribed value, a lock signal 75 is transmitted to a control circuit 20 from a lock detection circuit 100. After the lock signal 75 is transmitted, the release button 22 is further depressed to close a release switch SW2, the control circuit 20 reads that the switch is closed, drives a throttle motor 13, and causes a mirror 15 to jump up, thereby completing exposure preparations. Then a shutter 14 is opened to pickup the image of an object on a solid-state image pickup element 26, and the image is recorded on a magnetic disk 42 attaining the prescribed rotational frequency.

Title: Adm signal reproducing device
Inventor: ISHIKAWA REI
IPC: H03M3/02
Filed: 1991-09-13
Abstract: PURPOSE:To improve the power supply control method. CONSTITUTION:An ADM signal stored in an adaptive delta modulation(ADM) memory 1 at a sender side is subject to PW modulation by a PW modulation section 2, the result is fed to a reproduction section, an ADM decode section 3 of the reproduction section decodes the sent ADM signal and a D/A converter circuit reproduces the decoded signal into the original signal. In this case, a trailing edge detection section 4 in the ADM signal reproduction device detects a 1st trailing signal of the sent ADM signal to generate a power ON signal. While the power ON signal is being outputted, a counter 5 counts clocks and is reset by an OS signal fed from the trailing edge detection section 4. When transfer data are finished and a succeeding unit signal is absent, no OS signal is outputted, the counter 5 continues the count of the clock and when the count reaches a prescribed value, the counter 5 sends an OFF signal to turn off the power supply of the reproduction section.
