Description

The present invention relates to a timer device suitable for use in a tuner device with a timer.

[Outline of Invention]

According to the present invention, after a specific test code is input to the transfer data input port of the controller in which the timer program is controlled by the plurality of operation keys or the data input to the transfer data input port, all the plurality of operation keys are input. ,
When the pushes have been completed in a predetermined order, the entire display of the display device is turned on so that not only the operation keys but also whether the display device operates normally can be easily known. It is a thing.

[Conventional technology]

A tuner device with a timer device that incorporates a controller (microcomputer) has been proposed. This is to control a timer program in the controller by operating a plurality of operation keys, turn on / off the power of the tuner device based on the control, and receive a desired broadcasting station.

[Problems to be solved by the invention]

The above-mentioned timer device has to check whether all its functions normally operate after the manufacture or after the service, but the number of operation keys is large and the number of stored programs is large. It takes a lot of time to check each one, and it takes an extremely long time to confirm if the program is booked several weeks ahead. There was a problem.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention causes a controller (7) to input a specific test code from its transfer data input port (7b), and then a plurality of operation keys (8a) When all operations have been completed in the specified order, all the displays are turned on in the display device (9) connected to the controller (7), and the operation order of the operation keys may be wrong, or either When the contact failure of the operation key or the circuit system thereof is abnormal, this is displayed by the display device (9).

[Action]

When all the operation keys have been operated, all the displays on the display device are displayed, it is confirmed that all the operation keys are normal, and all the displays are displayed. If an abnormality appears on the display device during the operation of the operation keys in sequence, the abnormal operation key can be found at that time.

〔Example〕

Hereinafter, with reference to the drawings, an example of a timer device according to the present invention,
This will be described with reference to the drawings. This example is applied to an audio device capable of receiving FM and AM broadcasts.

In FIG. 1, a signal from an antenna (1) is supplied to a front end circuit (2), and a phase locked loop (PLL) including a local oscillator whose oscillation frequency is controlled by a controller (microcomputer) (7) described later. The reception frequency is determined by the frequency signal from the circuit (3), and the intermediate frequency signal obtained from this is the intermediate frequency amplifier circuit.
Amplified at (4), supplied to the next stage demodulation circuit (5) and demodulated, and further next stage multiplex (MPX) circuit (6)
To be separated into left and right signals. (6L) and (6R) are output terminals for the left signal and the right signal.

The controller (7) has a reception frequency control function, a timer program memory and a clock function. And the operation key (8a) of the operation unit (8) connected to this controller (7)
By the operation of, the instruction (command) is given to each function, that is, the timer program memory (7a) in the controller (7) is controlled, and the controller (7) instructs the power supply control circuit (10) based on the instruction. Then, the power is turned on / off at the set time, that is, the power of the tuner device and other audio equipment is controlled, and the control signal of the oscillation frequency is output to the PLL circuit (3) and set. At the time, the set broadcasting station is received or turned off.

In addition, a display signal is supplied from the controller (7) to the display device (9), and the current time, timer set time, F
The types of M and AM, the day of the week, whether the stereo state or not, and whether the muting state or not are displayed.

The input (instruction) to the controller (7) is made by operating the operation keys (8a) of the operation unit (8) described above, and a decoder of an operation signal from a remote operation device (remote control) (neither is shown). It is also performed by inputting to the transfer data input port (7b) of the controller (7) via. A wireless signal using infrared rays can be used from this remote controller.

In addition, the controller (7) has an external counter pulse input port (7c), and the number of pulses input to this or the period (frequency) of this pulse is also displayed on the display device (9).
It is designed to be displayed by.

An example of the arrangement state of the operation keys (8a) of the operation unit (8) described above is shown in FIG. In the figure, the operation (function) of each operation key (8a) is shown on the upper surface of each. For convenience of explanation, these operation keys (8a) are sequentially labeled with symbols a, b, c ,. Each of these keys designates a function described on the surface thereof. Of these, a brief description of a plurality of keys whose functions are difficult to understand, the a key is for tuning, and AM and 9kHz and 10 respectively for FM
It is tuned at 0 kHz intervals, and the + side push raises the frequency, and the-side push lowers it.
The d key stores the frequency to be received, that is, the broadcasting station selected as described above, and can store ten or more stations as required. The b key is used to sequentially switch and receive the broadcasting stations stored as described above at regular time intervals. The e key is used to push the clock function in the controller (7) when it is set to the correct time. The g key is used to set the power on / off time of the audio device, the i key is used to set the timer program only once, and the j key is used to receive the same broadcasting station at the same time every weekday. It is used when setting. The f key is for instructing whether or not to execute the above-mentioned program.

In such a device, it is difficult to know whether or not the operation is performed as instructed by the operation key (8a) without actually operating the device. Requires a very long time of 2-3 weeks, which is completely unsuitable for the post-manufacturing inspection of the tuner and the subsequent service to the user.

Therefore, in the present invention, a test code generator (11) is provided, and after this, for example, a specific test code of 8 bits is inputted to the controller (7) through its transfer data input port (7b), The test is performed by operating the operation unit (8).

An example thereof will be described below with reference to the flowchart shown in FIG.

First, when you turn on this tuner, the controller
(7) also becomes active, the clock function works, and the clock is started, which is displayed by the display device (9) (step (2
0)). Immediately after the power is turned on, SUN (that is, Sunday) and AM 12:00 are displayed as shown in FIG.
It is assumed that the time display starts from this.

In this state, as described above, the test code is supplied from the test code generator (11) through the transfer data input port (7b) to the controller (7) as shown in step (21). This test code is controller
Confirmed by confirmation means in (7) (step (22))
Then, the key test (step (23)) is started.
This is to sequentially operate (push) the operation keys (8a) of the operation unit (8) one by one as shown in steps (24a) ... (24v), and the operation sequence is predetermined. In this example, the symbols are displayed in the order of a, b, c ... In the case of the a key, the minus side is pushed first, and then the plus side is pushed.

Operation keys (8a) according to the order determined in this way
If there is no failure in all of the controller (7), the operation unit (8) and the display device (9) when the v key (ENTER key) is pushed at the end (when normal)
Is turned on in the display device (9) (step (25)). From this, it can be seen that the device operates normally. At this time, if any display is not lit on this display device (9), it means that the part of this display device (9) related to that display is defective, and this causes the display device (9). Can know whether or not it operates normally. After a certain period of time (for example, 1 second) elapses after the normal operation is detected in this way,
As shown in step (26), since the display device (9) returns to the original display state, that is, the normal display state (step (27)), it is not necessary to perform any operation for recovery.

When the operation keys (8a) are pushed in sequence and the operation is canceled midway, a predetermined time, for example, 30
After a lapse of seconds, the above-mentioned test state is automatically canceled and the original state is restored. In this case, you can start over by entering the first test code.

Also, in the sequential push operation of the operation keys (8a), if the order is incorrect, the one currently displayed on the display device (9), that is, SUN and AM 12:00 are all turned off. You can see that you made a mistake in the push order (step (28)). After all the lights are turned off in this way, if a certain period of time, for example, one second elapses, the display is returned to the original display state (step (2
9)). Therefore, in this case, it is sufficient to start over from the input of the first test code.

Further, it is assumed that, during the sequential push operation of the operation keys (8a), for example, the i key is pushed to turn off all of the above-mentioned displayed items of the display device (9). In this case, it can be seen that the circuit system related to the h key before the i key or the contact state of the h key is bad. That is, the i key is pushed next to the g key without pushing the h key, which is equivalent to a case where the above-mentioned push order is wrong.
In this way, the faulty part can be easily found. Even after the light is turned off in this manner, the display device (9) returns to the original display after a lapse of a certain time, that is, one second as described above.

In the above description, when the operation keys are pushed in the wrong order or the operation keys have a bad contact, the display device
Although all the displays in (9) are turned off, the blinking operation may be performed at a constant cycle.

〔The invention's effect〕

As described above, according to the present invention, by pushing a plurality of operation keys in a predetermined order, it is possible to determine the quality of the operation keys, and in the normal case, the entire display of the display device (9) is displayed. Since the light is turned on, there is a feature that the failure of the display device (9) itself can be recognized at the same time as the above determination.

Also, if an error display such as turning off all is made during the sequential push of the operation unit (8), it is also known that there is an abnormality in the key before the operation key (8a), so it is easy to find the abnormal location. It has the characteristics that can be.

Moreover, since the key code is first inputted after the test code is inputted from the transfer data input port (7b), the general user cannot perform such a test, so that the unknown user can When the operation keys are mishandled and accidentally pushed in the above-described order, it is possible to avoid the situation where all the display states are displayed or the operation sequence is erroneously brought into the all-off state, and there is no possibility of being mistaken for a failure.
