Abstract

PURPOSE:To realize the timer operation to a device having an optional remote controller input by storing a waveform of a remote controller in advance. CONSTITUTION:A time for starting a timer is set to a timer register 2 by an input device 1, a clock counter 4 always represents a current time and a comparator always compares the content of the timer register 2 and the content of the clock counter 4. When the both are coincident, a coincidence signal 5 is outputted to an output driver g to generate a remote control signal with an output waveform set by a waveform memory 8. Furthermore, in order to generate a waveform of an optional remote control signal 10, a remote control input 6 is read by a waveform read section 7 in advance and is stored in the waveform memory B. When the coincidence signal 5 is generated afterward, the output driver 9 outputs the waveform of the waveform memory 8 as the remote control signal 10. Thus, the timer operation is implemented by using the remote control signal to the device storing the remote control waveform.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a timer device, and particularly to a timer device with a built-in remote control.

[Conventional technology]

This year, some timer devices are equipped with a built-in remote control, and when the set time comes, they send out a transmission signal such as infrared rays to operate a remote device. Such a timer device includes a timer register to set the time, a counter to measure the time, a comparator to generate a match signal when the counter matches the set time, and an output to output a specific waveform based on the match signal. He was fired from the department.

[Problem to be solved by the invention]

Since the conventional timer device described above can only output a specific waveform, the devices to be operated are also specified. That is,
There was a drawback that only the equipment on the main body side that had a timer device with remote control as an accessory could be operated.

An object of the present invention is to provide a timer device that outputs an arbitrary output waveform.

(Means for Solving Fraud) The timer device of the present invention includes a timer register for setting time, a clock counter for measuring time, and a coincidence signal when the time of the clock counter and the time of the timer register match. a converter 1/data that outputs a waveform, a waveform reading unit that reads a remote control input waveform, a waveform memory that stores the read waveform, and an output driver that outputs the remote control waveform of the waveform memory when the coincidence signal is output. It is characterized by having the following.

〔Example〕

FIG. 1 is a block diagram for explaining a first embodiment of the present invention. As shown in the figure, the input device is an operation key or switch, and is used to set an arbitrary time. Timer register 2, comparator 3, clock counter 4
are semiconductor circuits, and a comparator 3 compares the value of the clock counter 4 and the value of the timer register 2.

A match signal is output from the comparator 3 to the output driver 9. The output driver 9 sequentially sends out waveform No. 13 from the waveform memory 8 as a remote control signal ]O when the coincidence signal 5 is input.

The time at which the timer starts is set in the timer register 2 using the input device 1. Clock counter 4 always indicates the current time, and the value of timer register 2 and clock counter 4
Converter 3 constantly compares the values of . If the two match, a match signal 5 is output to the output driver 9, thereby generating a remote control signal having the output waveform set by the waveform memory 8.

Further, in order to create a waveform of an arbitrary remote control signal 10, the remote control signal 6 is read by a waveform reading section 7 and stored in a waveform memory 8 in advance. Thereafter, when the coincidence signal 5 is generated, the output driver 9 outputs the waveform in the waveform memory 8 as the remote control signal 10.

As explained above, according to the present invention, a timer operation can be performed using a remote control signal for a device in which a remote control waveform is stored in advance.

FIG. 2 is a block diagram for explaining a second embodiment of the present invention. As shown in the figure, there are N timer registers 21, timer registers 1 to N, and correspondingly there are 816N waveform memories.

In this embodiment, there are N timer registers and N waveform memories, so by storing the remote control waveforms and operation times of various operations of different devices in sequence, you can perform any operation up to N times at any time. It has the advantage of being achievable.
