The present invention relates to an electronic clock which shows a time display method of a conventional needle and an electronic clock in a dot graph method, and in particular, improves the time display method of a utility model filed by the applicant (Application No. 90-16774). It relates to a digital graphic electronic clock.

Conventional electronic clocks display time with a needle-type clock with a dial and a liquid crystal display clock. However, it was necessary to develop electronic clocks with various functions and forms in order to satisfy the needs of modern people who value individuality. For this purpose, Korean Utility Model Registration Application No. 90-16774, filed by the applicant of the present application, uses a dot display device (LED, LCD) as a time display method. The time is indicated by various waveforms and waveforms. The invention is time display; 12 elements, min; 12 elements, seconds; Using 12 elements, hour is divided into one hour unit, minute is divided into 5 minute unit, and second is united into 5 second unit. Red, yellow, and blue elements are used to distinguish hour, minute, and second, respectively.

However, the digital graphic electronic clock does not easily identify the correct time, and therefore, a problem arises in that the time which is the original purpose of the clock cannot be recognized.

An object of the present invention is to improve the time display device of a digital graphic electronic clock so that time can be easily recognized.

The present invention will be described in detail with reference to the accompanying drawings.

1A is a perspective view of a digital graphic electronic clock filed by the applicant of the present invention. Here, the arrangement of visual display devices (LED, LCD, etc.) is time; 12 elements, min; 12 elements, seconds; It is composed of 12 elements and red, yellow, and green display elements 12 are used to distinguish each of them.

In other words, the hour is displayed in units of one hour and minutes and seconds in units of five minutes and five seconds, respectively. 1B is a digital graphic perspective view of the present invention for solving this problem. In the present invention, the display element 12 is composed of the display element 25. The hour is 12 hours, the minute is 14 elements, and the second is 14 elements. It is displayed in units of minutes and 1 second to make the time easy to recognize. In other words, the minute and second display uses two kinds of devices of different sizes, and one element consists of 5 units to display 10 minutes and 10 seconds, and the other element consists of 9 units of 1 minute and 1 second. Represents a unit. In addition, the colors are displayed in red, yellow, and green for easy identification.

2 shows a circuit diagram using a shift register, in which a pulse of one second period is generated by the superdisplay shift register circuit 21, the branch display shift register circuit 22, and the time display register circuit 23. It is connected to the pulse generator 24 and the display element 25 which shows hours, minutes, and seconds. The pulse generator 24 generates a pulse of one second period to drive the second shift register 21. When the seconds display register 21 reaches 60 seconds, it becomes one minute, and the seconds display register 21 is cleared and shifted to the minutes display register 22. When the minute display register 22 reaches 60 minutes, the hour display register 22 is cleared and shifted to the hour display register 23 in one hour. The second and minute shift registers 21 and 22 are composed of 14 display elements so that nine display elements display 1 second and 1 minute intervals, and five display elements display 10 seconds and 10 minutes. The time display shift register 23 is composed of twelve display elements each representing one hour. In addition, the adjustment switch 26 is connected to the hour and minute shift registers 22 and 23 so that the hour and minute can be adjusted. The shift register can be easily used in the present invention by making one chip.

FIG. 3 is a circuit diagram using a microprocessor instead of the shift register of FIG. The circuit diagram is constructed by connecting the microprocessor 31 having the oscillation circuit OSC with the display element 25 and the time adjustment key 32. The time display is the same as the display element 25 of FIG. 2, and the microprocessor 31 operates as follows. When a pulse (pluse) having a one-second period is input while the initial time is set, the second display device is turned on while the unit output unit is shifted to display the time. When the most significant bit of the unit output port is set in this way, the unit output port is cleared and the unit output unit 10 is cleared, and the unit output is shifted to the output port to display the unit of minute in the unit distribution. do. When the most significant bit of the single-minute minute display output port is set, the ten-minute minute display output port is shifted to the clear-dot display time output port to display the hour. An adjustment key 32 is connected to the microprocessor 31 to allow adjustment of hours and minutes.

According to the present invention configured as described above, the shift register circuit and the microprocessor circuit can be easily recognized by displaying the time in decimal notation, unlike Utility Model No. 90-16774, filed by the applicant. It can be seen that the electronic clock of various forms can be configured by arbitrarily changing.
