Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to a timer device which is suitable for use in a timer tuner, for example, in which timer operation is controlled by a microcomputer.

[Description of the invention]

In the present invention, the timer is operated by a microcomputer. An example of how to perform the ff1J cape is to perform a test routine using data obtained from a predetermined input port of a microcomputer in a timer device that is commonly used in a timer or tuner. By supplying routine data, the timer operation can be easily and reliably tested in a short period of time without actually performing operations to set the timer operation using operation buttons or the like.

[Conventional technology]

Conventionally, a tuner with a timer function has been proposed, in which a tuner for receiving FM broadcasts, AM broadcasts, etc. is provided with a timer function. What tuner has this timer function?For example, the tuner's i! Controls each virtue operation of 4 stations, etc. ,
Furthermore, a Nayuna with a timer function has been proposed which can instruct this timer operation to 11 times, for example 4 times (1&).

[The problem that the invention attempts to solve]

By the way, at the time of manufacturing the timer device as described above,
It is necessary to check whether the timer operates normally. This test may be performed as described above. After the inspector sets each function by pressing an operation button, etc., the inspector waits until the set predetermined time is reached and confirms whether the predetermined operation is performed at the predetermined time, which requires time and effort. There was the inconvenience of having to wait until the set time. Particularly in the case of a device that can set a plurality of timer operations, it takes a lot of time and effort to check all the sets. Further, when the inspector presses an operation button or the like to set the setting, there is an inconvenience that if the operator presses the wrong button, the inspection work must be repeated.

〔Example〕

Hereinafter, one embodiment of the timer device of the present invention will be described with reference to the accompanying drawings. The timer device of this example is a tuner with a timer function, which is a tuner of an audio device incorporating a timer function. The present tuner with a timer function is constructed as shown in FIG. In Figure 1, (17
is shown as a tuner with a timer function as a whole, and supplies the received broadcast signal received by the antenna α to the front end circuit (2) in the tuner (1). Then, a microcomputer (7-engine clock loop circuit, which constitutes a local oscillator whose oscillation frequency is controlled by force), which will be described later, is installed.
The output signal of the PLL circuit (6) (hereinafter referred to as PLL circuit) is supplied to the front end circuit (2), and the reception frequency is determined by the front end circuit (2). This front end circuit (
2) output signal to an intermediate frequency amplification circuit (4J and detection circuit
! i! r (5) to a multiplex circuit (hereinafter referred to as MPX circuit) (8), and this MPX circuit (
The left and right audio signals obtained at the output side of 8) are supplied to the respective audio signal output terminals (6L) and (6fL). Here, the oscillation frequency of the above-mentioned PLL circuit (3) for determining the receiving frequency (receiving broadcasting station) is controlled by the microcomputer (7). That is, each operation key (8a) of the operation unit (8) connected to the microcomputer (7)
Based on instructions from the operation of the microcomputer (7
) outputs the # signal for each oscillation frequency to the PLL circuit (3), and the oscillation frequency! ! (reception frequency). In addition, operation instructions to the microcomputer (7) are given to the operation section (8).
In addition to the operation described above, the operation is also performed by inputting an operation signal from a remote control device (not shown) to the transfer data input capacitor (7a) of the microcomputer (7) via a decoder (not shown). In this way, various broadcast signals such as FM broadcasts are received.

In addition to this reception frequency control function, the microcomputer (7) has a timer function and a clock function related to this timer function. The operation instruction for this timer function is also given by the above-mentioned operation unit (8) or the remote control device, and this operation instruction is stored in the timer program memory (7b) in the microcomputer (7).
Based on this operation instruction, the microcomputer (7)
The power supply control circuit Ujima controls the power on/off of the receiving circuit system of the tuner (1) and other equipment such as the amplifier unit fIL (not shown) connected to this tuner (IJ).
At the same time, the microcomputer (7) supplies a display signal to the display panel (9) to indicate the operation of the timer set by K. Also, X
In conjunction with the supply of source control (ff signal), a PLL circuit (3
) to reproduce the received signal of the desired broadcasting station.

Here, the procedure for setting the timer operation using the operation unit (8), for example, will be described below. First, the time of the clock function of the tuner with timer function is set in advance to the current time by operating the operation key (8a). Then, use the operation key (8a) to set the power off time, off time, and reception frequency to be received by the tuner (
. The instructions set by each operation key (8a) are stored in the timer program memory (7b) provided in the microphone computer (7), and when the off time comes, the tuner (1) etc. is turned on and set. The broadcast signal of the selected frequency is received and played back, and when the off time comes, the power of the tuner (1) etc. is turned off and reception of the broadcast signal is stopped.

In this way, the timer operation is performed. Note that the power supply required to operate the timer function is always on.

Regarding the test of the timer function of the tuner with timer function (1) of the present example, which is thus performed.

The following description will be made based on the flowchart shown in FIG.

This timer function test is performed when the tuner (1) is manufactured. First, the tester who conducts the test connects the test code data generator αυ to the transfer data input capo (7a) of the microcomputer (7), as shown in FIG. The test code data generator aυ supplies the test code to the microcomputer (7b) that performs the test and stores it in the timer program memory (7b).
) determines and memorizes this test code, and then resets the on time (for example, 11:01 p.m.), off time (for example, 1:02 p.m.), and the reception frequency based on this test code. Set the time on the clock (for example, set the clock to 1:00 p.m. and fast-forward the clock, for example, to a speed several tens of times faster. Then, if the timer function is normal, when the clock reaches 1:01 p.m. 1ics turns on and receives the set frequency, and turns off at 1:02pm.Then, after this IE source is turned off, the clock returns to normal speed. The timer operation data stored in the timer program memory (7b) is erased.

By operating in this way, you can confirm that the timer function is working properly.

By being able to perform the test in this way, the examiner can perform the test without pressing any operation keys (8a), etc., and it is possible to easily perform the test without wasting time on the operation. Operation errors are eliminated. Also, since the clock is fast forwarded during the test, timer operation can be performed in a short time. For example, from inputting the test code to erasing timer operation data can be completed in about 12 seconds. Especially when the timer is used multiple times. When testing the operation, the time is significantly reduced.Also, since the test code is input to the microcomputer (7) through the transfer data input port (7a) of the remote control device, the test code is input to the microcomputer (7). There is no need to add a dedicated input port for the tuner (17), and the manufacturing cost of the tuner (17) does not increase.

In the above embodiment, the test code data generator αυ is separate from the tuner (IJ); It is also possible to store a test code in advance and perform a test using this test code.Furthermore, in the above embodiment, the timer device was built into the tuner (1), but IW even if it is separate from the tuner.
It can be configured in one way. Furthermore, the present invention is not limited to the above-mentioned embodiments, and without departing from the gist of the present invention,
Of course, many other configurations are possible.
