Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer device that has two or more systems of control output terminals and can use a combination of control output signals. Some conventional timer devices are capable of controlling multiple systems, but these simply control the multiple systems individually, and operate other systems based on a combination of set times. I couldn't do that. Therefore, the present invention provides a novel timer device that has been made in view of the above points, and will be described below with reference to the drawings. FIG. 1 is a block diagram showing a timer device of the present invention, and FIGS. 2A to 2D are waveform diagrams for the same block diagram. In the figure, 1 indicates multiple control output terminals 2, 3, 4.
5, 6 are power lines, 7 ,
8 and 9 are the first, second and third relays, respectively, and the relay contacts 10, 11, 12, 13 and 14, 1, respectively.
5, and a first relay, a second relay, and a third relay each having a first relay drive circuit 16, a second relay drive circuit, 17, and a third relay drive circuit 18. 19 is a first load device having controlled devices 20, 21, and 22; 23 is a fourth load device having a fourth relay drive circuit 28 that is controlled in response to switching of selection switches 25 , 26, and 27 provided in selection means 24; With the operation of the fourth relay 23 , the relay contacts 29 and 30 are closed, thereby causing the second load device to close.
31 works. Next, an example of an embodiment of the present invention will be described. The controlled devices 20, 21, and 22 are a cassette tape recorder, an EL cassette tape recorder, an open reel tape recorder, and a second
When a tuner is connected as the load device 31 ,
It is assumed that the tape recorders serving as the above-mentioned controlled devices 20, 21, and 22 record popular, semi-classical, and classical music, respectively. First, when each control output terminal 2, 3, 4 of the control circuit 1 is at a low level, each relay 7 , 8 , 9 is off, and both the first load device 19 and the second load device 31 are in an inoperable state. There is. When the control output terminal 2 becomes high level during the period _t1 and the period _t5 according to the set time shown in FIG. 2A due to the operation of the control circuit 1 , the first relay 7 accordingly becomes The relay contacts 10 and 11 are operated, and power is supplied to the controlled device 20. At this time, the selection switches 25, 2 of the selection means 24
6 and 27 are closed as shown, the control output signal from the control output terminal 2 operates the fourth relay 23 via the diode 32 and the selection switch 25, and the relay contacts 29 and 30 are accordingly closed. , power is supplied to the second load device 31 . That is, the cassette tape recorder as the controlled device 20 and the tuner as the second load device 31 are supplied with power from the lines 5 and ₆ during periods _t1 and t5, and accordingly, the second load is Device 3
The received signal received by the tuner 1 is applied to the cassette tape recorder as the controlled device 20 via the line 33, and the received signal is recorded on the cassette tape. Next, power is supplied to the controlled device 21 during the period t ₂ and period t ₄ shown in FIG. 2B, and to the controlled device 22 during the period t ₃ shown in FIG. When the selection means 24 is set, power is supplied to the second load device 31 during periods t ₁ , t ₂ , t ₃ , t ₄ and t ₅ as shown in FIG. 2D. Therefore, predetermined signals are recorded on each of the cassette tape recorder, EL cassette tape recorder, and open reel tape recorder. Note that each selection switch 25, 2 of the selection means 24
6 and 27 are selectively set according to each controlled device of the second load device 31 , and accordingly the diodes 32,
33 and 34 are respectively turned on, and the fourth relay drive circuit 28 is operated.On the other hand, unlike in FIG. , second load device
31 is supplied with power in accordance with each period corresponding to when the selection switches 25 and 27 are turned on. As described above, according to the present invention, the two systems of load devices can perform corresponding operations in a predetermined combination for a predetermined period according to the operation of the control circuit.
