Reference numeral denotes input means having a built-in light detection circuit. The operation position of the light pen 3 on the screen of the CRT 1 is detected by a light pen counter 4.

The timer circuit 5 counts the time and supplies it to a central control circuit 8 which controls the entire apparatus. The main memory 6 stores a control program for controlling the operation of the device and various data. In a storage area constituted by a RAM or the like, a storage instruction flag 6a and the presence / absence of a program in which operating conditions are set in advance, There are provided storage areas 6b, 6c and 6d for storing a control program for a time condition for turning on the device and a time condition for turning off the device, respectively. In this embodiment, storage areas corresponding to eight types of devices are provided.

The I / O port 7 controls the input / output of on / off control signals for a plurality of devices (not shown). on/
The off control switch 9 directly performs on / off control of the device regardless of a program in which operating conditions are set in advance. The storage instruction switch 10 is a means for instructing whether or not the time of the on / off operation by the on / off control switch 9 and whether the on / off operation has been performed are stored in a predetermined area of the main memory 6. When storage is instructed by the storage instruction switch 10, the storage instruction flag 6a is set.

The operation of the above-described device on / off control by the home controller according to the present invention will be described with reference to the flowcharts shown in FIGS. For convenience, a control operation for one device will be described. First, the storage instruction flag 6a is cleared (S0), and the device control program storage areas 6b, 6c, 6d are cleared (S1). On / off of the storage instruction switch 10 is determined (S2), and if it is off, the process jumps to S5. If it is on, the setting / clearing of the storage instruction flag 6a is determined (S
3) If set, jump to S7. If it is in the clear state, the storage instruction flag 6a is set and the process returns to S2.
Jump to S7 via S3.

If the storage instruction switch 10 is off in S2, it is determined whether the storage instruction flag 6a is set / cleared (S5). If the storage instruction switch 10 is in the set state, the storage instruction flag 6a is cleared (S6) and the process jumps to S17. If it is in the clear state, the process jumps to S7. It is determined whether or not the on / off control switch 9 has changed (S7). If there is no change, the process jumps to S17. If there is a change, it is determined whether the on / off control switch 9 is on or off (S8). If it is off, the process jumps to S13. If it is on, the device is on-controlled via the I / O port 7 (S9).

The device is turned on (S9), and the setting / clearing of the storage instruction flag 6a is determined (S10). If the state is the clear state, the process jumps to S17. If the state is the set state, the storage area 6b is set to the state with the program (S11).
(S12), and jump to S17.

After it is determined that the on / off control switch 9 is off (S8), the device is off-controlled via the I / O port 7 (S13), and the setting / clearing of the storage instruction flag 6a is determined (S14). . If the state is the clear state, the process jumps to S17. If the state is the set state, the storage area 6b is set to the state with the program (S15).
And stores it in the storage area 6d (S16).
Jump to 17.

At S17, the presence / absence of the program is determined by the storage area 6b. If there is no program, the process returns to S2. If yes, the storage area 6c is checked to determine whether the ON time is stored (S18). If the ON time is not stored, the process jumps to S21. If the ON time is stored, the ON time of the storage area 6c is compared with the current time (S19), and if they do not match, the process jumps to S21. If they match, the device is turned on via the I / O port 7 (S
20) Return to S2.

In S21, the storage area 6d is examined to determine whether the off time is stored. If the off time is not stored, the process jumps to S2. If the off time is stored, the off time in the storage area 6d is compared with the current time (S22), and if they do not match, the process jumps to S2. If they match, the device is turned off via the I / O port 7 (S
23), and return to S2.

In order to clear the on / off times of the devices set as described above, the program shown in FIGS. 2 to 4 is started from the beginning, or a program clear means is provided for each device. , The storage area 6b is set to the non-program state.

Although the present embodiment has been described with reference to a case in which one set of ON / OFF time storage areas 6c and 6d is provided for one device, a plurality of ON / OFF time storage areas may be provided. Thus, the same effect as in the present embodiment can be obtained. Further, in this embodiment, the case where the storage area of the on / off control program for eight devices is provided is described, but the number of devices is not limited to this.

Also, in the present embodiment, turning on / off the home device is performed.
Although the home controller that controls off is described, it is also applicable to on / off control of other devices such as industrial devices.

[0019]

As described above, the on / off control device of the present invention stores the time at which the switch was turned on / off without inputting the operating conditions of the equipment in detail, and thereafter, the on / off control of the equipment is performed. Since ON / OFF is automatically controlled, there is an excellent effect that the operation is simple and that an unintended operation of the device due to an incorrect setting of the control condition can be prevented.
