DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic time setting device, and more particularly to an automatic time setting device for terminal equipment connected to a telephone line.

[0002]

2. Description of the Related Art A conventional automatic time setting apparatus of this type will be described with reference to the drawings.

FIG. 4 is a block diagram showing an example of a conventional automatic time setting device.

FIG. 4 shows a first conventional example of an automatic time adjustment apparatus disclosed in Japanese Patent Application Laid-Open No. 5-341060. A time signal receiving means 11 connected to a telephone line automatically calls a time signal service. To receive the time signal. The hourly sound detector 12 detects only a specific hourly sound (for example, 0 seconds and 30 seconds) from the received hourly sounds. The error judging means 13 compares the detected specific time signal with the current time signal from the clock circuit 14 to calculate a time difference between the two, and judges whether the clock circuit 14 is advanced or delayed. The correction instruction for each case is issued to the clock circuit 14. In this correction control, when the clock circuit 4 is set first, the time signal service is called and 0 is set.
The control unit 15 is configured to perform the second start and to control the correction unit 15 to perform the correction control within a time error of ± 15 seconds due to an error of the oscillator itself in the clock circuit 4.

A second conventional example disclosed in Japanese Patent Laid-Open No. 6-197196 has a CPU and a clock mechanism, and is connected to a slave station device and a time signal guide station via a subscriber telephone line. The telemeter master station device is provided with voice recognition means and tone detection means, and uses a voice signal and a tone signal from the time signal guide station (for example, NTT No. 117) to periodically and automatically set the time of the clock mechanism. The correction is made.

[0006]

In the case of the first conventional example, the time signal sound detecting means detects only specific time signal sounds (0 second time and 30 second time). Further, since the control means performs the correction control within a time error of ± 15 seconds due to the oscillator itself in the clock circuit, there is a problem that the time cannot be corrected for an error of 15 seconds or more.

In the case of the second conventional example, the voice recognition means is provided, the time is recognized based on the voice content based on the received time information, and the subsequent tone signal is detected by the tone detection means. There is a problem that the whole apparatus is complicated and expensive. (Purpose) A first object of the present invention is to provide an automatic time adjustment device capable of time correction even if there is an error of 15 seconds or more.

A second object of the present invention is to provide an automatic time setting device that recognizes only the presence or absence or length of a time signal and a voice and does not require voice recognition means.
