Description

[Detailed explanation of the idea] The present invention relates to a clock device.

Conventionally, in electronic digital watches, one display element only displays one time measurement output, and for this reason, it has been difficult to display seconds in watches with a small display space.

Therefore, the purpose of the present invention is to eliminate the above-mentioned drawbacks and to provide a timepiece device in which all the hours, minutes, and seconds can be visually recognized using a display element that displays the hours and minutes, and the units can be read by mistake. shall be.

The present invention will be explained below based on the drawings.

1 and 2 show the same display element, which selectively displays two time units. 1 is an oscillator such as a crystal oscillator, 2 is a frequency divider, 3,
4...8 is a decimal counter for seconds, respectively.
10th place hexadecimal counter, minute 1st place decimal counter, minute
They are a 10th place hexadecimal counter, a 1st place decimal counter for time, and a 10th place binary counter for time. 9,10...
22 is an and gate, 23, 24...32
is an OR gate, and 33, 34, and 35 are inverters. 36 and 37 are and gates,
38 is a decoder for seconds and minutes, and 39 is a decoder for seconds and minutes. 40 is a display section, 41, 42, 45,
44 is the 1st place of the second and the 1st place of the minute, respectively, and the 10th place of the second.
This is a display element that has a number pattern made up of liquid crystals, light emitting diodes, etc. that displays the 1st digit, the 1st digit of the minute, the 1st digit of the hour, the 10th digit of the minute, and the 10th digit of the hour.
The display elements 41 and 42 constitute a first display element, and the display elements 43 and 44 constitute a second display element. 45 is an instruction display element that indicates that the display elements 43 and 44 are displaying the time, and 46 is an instruction display element that indicates that the display elements 43 and 44 are displaying minutes. The forming numeral 47 is an instruction display element that indicates that the display elements 41 and 42 are displaying seconds, and forms a pattern S. 48 is a changeover switch, 48a is a contact piece, 48b, 4
8c, 48d, and 48e are contacts. 49 is a fast forward switch, 49a, 49b are Nand gates, 49c is a contact piece, 49d, 49e
is a contact point. 50 is an OR gate, 51 is an inverter, 52, 53...63 are AND gates, and 64, 65...68 are OR gates. 69 and 70 are minutes and hours, respectively.
It is a 10th place decoder for minutes, hours and 71
is an inverter.

Next, the operation will be explained. First, contact piece 48a
A case will be explained in which the contact point 48b is connected to the contact point 48b.
In this case, contacts 48c, 48d, and 48e are held at "1" (described below as logic levels "1" and "0"), and one input of AND gates 9, 10...22 is held at "1". . or gate 31, 32
Since one input is held at "0", the 1 second signal supplied to the other input of the OR gate 32 is supplied to the AND gates 9, 11...19, 21, and its phase is inverted by the inverter 33. The 1 second signal is sent to AND gate 1 via OR gate 31.
0,12...20,22. Therefore, the timing outputs of counters 3 and 4 and counters 5 and 6 are:
AND gates 9, 10...22, OR gates 23, 24...29 and decoder 3 every 0.5 seconds
The signals are supplied to display elements 41 and 42 via terminals 8 and 39 for display. At this time, the display elements 43 and 44 display the time as shown in FIG. 2, and the instruction display element 47 displays when the display elements 41 and 42 display seconds.

When the contact piece 48a is connected to the contact point 48b in this manner, minutes and seconds are displayed alternately every 0.5 seconds.

Next, when the contact piece 48a is connected to the contact 48c, the contact 48c is held at "0", so the AND gates 10, 12...20, 22 are closed, and the contact 48b is held at "1". , or gate 3
The outputs of 1 and 32 are held at "1". Therefore, the time outputs of the counters 3 and 4 are supplied to the display elements 41 and 42 in the same manner as described above to display the seconds. At this time, time is displayed on display elements 43 and 44, and instruction display elements 45 and 47 are displayed to indicate that time and seconds are displayed.

Next, when the contact piece 48a is connected to the contact point 48d, one input of the AND gates 9, 11...19, 21 is held at "0", and the AND gates 10, 12...
Since one input of 20 and 22 is held at “1”,
The display elements 41 and 42 are supplied with the clock outputs of the counters 5 and 6 and display the minutes. At this time, the instruction display element 45 is displayed to indicate that hours and minutes are being displayed.

Next, when the contact piece 48a is connected to the contact 48e, the AND gates 53, 55...59, 61 are closed, the AND gates 52, 54...58, 60 and the AND gates 62, 63 are opened, and the counter 5 ，
The outputs of counters 3 and 4 are displayed on display elements 43 and 44, and the outputs of counters 3 and 4 are displayed on display elements 41 and 42, respectively. Indication display elements 46 and 47 are also displayed to indicate that minutes and seconds are being displayed.

FIG. 3 is a front view of the display section 40 implemented in a wristwatch.

FIG. 4 is a schematic diagram of another embodiment of the display section,
Reference numerals 72 and 73 indicate instruction display elements for indicating that the display elements formed with numerical patterns are displaying seconds and minutes, respectively, and are displayed in the same manner as above.

FIG. 5 is a schematic diagram of still another embodiment of the display unit. 74 is a display section, 75, 76, 77,
Reference numerals 78 indicate indication display elements representing hours, minutes, minutes, and seconds, respectively, forming patterns of H, M, M, and S, respectively. Instruction display elements 75, 76, 7
7 and 78 are display elements 41 and 42 and display element 4
3 and 44 are for selectively displaying the displayed time units.

FIG. 6 shows the instruction display elements 45, 75, shown in FIG.
This is an example of drive circuits 76, 77, and 78.
79 is an OR gate, 80, 81, and 82 are AND gates, and 83, 84, 85, and 86 are inverters.

Note that the same reference numerals as in FIGS. 1 and 2 indicate the same parts, and the display elements 41, 42, 43, and 44 are driven in the same manner as in the embodiment of FIGS. 1 and 2.

When the contact piece 48a is brought into contact with the contact point 48b with the above configuration, the minutes and seconds are displayed on the display elements 41 and 42.
Displayed alternately every 0.5 seconds, display elements 43, 4
4, the time is displayed, an instruction display element 75 is displayed, and an instruction display element 77 and an instruction display element 78 are displayed in synchronization with the minutes and seconds, respectively.

Next, when the contact piece 48a is connected to the contact point 48c, the time and seconds are displayed on the display section 74, and the instruction display element 75 and the instruction display element 78 are also displayed.

Next, when the contact piece 48a is connected to the contact point 48d, the hour and minute are displayed on the display section 74, the output of the inverter 85 becomes "1", and the instruction display element 45
is displayed. When the contact piece 48a is connected to the contact 48e, the minutes and seconds are displayed on the display section 74, and the instruction display elements 76 and 78 are displayed.

In the above embodiments, the indicator display elements each having a pattern formed thereon are used; however, the present invention is not limited to this, and the character pattern may be formed by character elements made of liquid crystals, light emitting diodes, etc.
Characters may be selectively displayed via a decoder.

As described in detail above, according to the present invention, the display element for displaying hours and minutes is used to selectively display hours and seconds, minutes and seconds, and alternating hours and minutes and seconds. Hours, minutes, and seconds can be displayed simultaneously even when the display space is small, and since the displayed units are selected and displayed at the same time on the indicator display element, there is no need to make a mistake in the displayed content, making it easy to use in practical applications. The effect is huge.
