Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pointer-type world clock that uses a 12-hour clock to display the time of two regions.

[Prior Art] A world clock is a digital type or an analog type,
Many products are currently on the market. Of these, the digital display method of world time is 24
The time of the area selected by the time system is displayed, or the time of the area selected by the 12-hour system is displayed.
There are things such as AM and PM that display morning and afternoon.

On the other hand, the world time display in analog form is equipped with a pointer that indicates a certain area, and if the pointer is adjusted to the selected area, the hour hand with a 24-hour hour hand will set the time in the selected area to 24 hours. Or display the time of the place name from the position of the place name to be selected on the rotating disc by rotating the disc with the place name once in 24 hours.
Alternatively, there are various methods such as a disc that makes one round for 24 hours or a pointer and a bezel attached to the outer circumference of the dial to know the time in another region.

In this way, the main world clocks currently on the market display the selected area with a 12-hour system and a 24-hour system with the digital type, and with the analog type, the selected area is displayed with 24 hours.
The time display is used.

[Problems to be solved by the device]

As described above, the world clock can be used to know the time in other regions with one clock. However, the digital world clock can display the time of the selected area in a 24-hour system, a 12-hour system, etc., but the analog world clock displays the time of the selected area in a 24-hour system. However, the analog world clock had problems such as being difficult to read and hard to read for those who were used to the clock displayed in 12-hour system.

The purpose of the present invention is 12
It provides a 12-hour world clock that is easy for those who are familiar with time-based clocks to see.

[Means for solving the problem]

The pointer-type world clock of the present invention for achieving the above-mentioned purpose has 24 regions for selecting the time, and the pointer for indicating the region indicates two regions having a time difference of 12 hours with two pointers. By displaying the two areas with a 12-hour electronic timepiece and using different colors or shapes for the two area indicator hands, one can be used as the morning area indicator hand and the other as the afternoon area type hand. The feature is that it is possible to determine whether the selected area is morning or afternoon.

[Action]

That is, the 12-hour system time display of the selected region of the pointer type world clock in the present invention is divided into a region selected by the pointer indicating the region to be selected and a region having a time difference of 12 hours from the selected region. By indicating one area and the two area indicators having different colors and shapes from each other, by deciding one area indicator needle in the morning and the other area indicator needle in the afternoon,
The time of the selected area can be displayed on a 12-hour electronic clock.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view showing the external appearance of the pointer type world timepiece of the present invention, and FIG. 2 shows the regions at the times shown in FIG.
It is a front view of the clock which displayed whether it was morning or afternoon.

In FIG. 1, 1 is an electronic timepiece, 2 is an hour hand, 3 is a minute hand, 4 is a region indicating hand having two pointers, and the lower left hand indicating the morning and the morning hand indicating the morning region
4a, and in the embodiment, a sun mark is added to indicate morning. In addition, the pointer on the upper right is the afternoon hand 4b indicating the afternoon and indicating the area of the afternoon, and in the embodiment, a crescent moon mark is added to indicate the afternoon.

The two areas indicated by the area indicator 4 are set so that there is always a time difference of 12 hours. Reference numeral 5 is an hour / minute scale, 6 is an area name display portion, and in the embodiment, 24 hours area names are displayed so that areas that differ by 1 hour due to a time difference are arranged next to each other. Across the center of 1
A 12-hour time zone is located. 7 is a crown, which can be pushed and pulled to each position of 0 stage, 1 stage, 2 stage,
The switch 54, which will be described later, is operated by pulling the crown 7 to the second stage, and the switch 55, which will be described later, is operated by pulling the crown 7 to the first stage. Next, 8 and 9 are push buttons, and by pushing the push button 8, a switch to be described later will be described.
By pressing the push button 9 of 56, the switches 57 to be described later are respectively operated. 10 is a dial.

In the embodiment shown in FIG. 1, the hour hand 2 and the minute hand 3 to 10 o'clock
It can be read as 10 minutes, and the morning hand 4a of the area indicator needle 4 indicates the symbol TYO on the area name display portion 6 indicating Tokyo.
The afternoon hand 4b points to the symbol RIO on the area name display portion 6 indicating Rio de Janeiro. From this, it can be read from electronic clock 1 that Tokyo is 10:10 and Rio de Janeiro is 10:10.

The morning-afternoon boundary line 13 shown in Fig. 2 is at 10 o'clock in Tokyo, and every time one hour elapses, the morning-afternoon boundary line 13 is in the direction of forward rotation, that is, as indicated by arrow 14, there is a gap between place names. I will go. As a result, morning area 11 and afternoon area 12
Will also change.

At this time, when the push button 8 is pressed, the regional indicator 4 makes one rotation in the reverse direction (clockwise is forward, counterclockwise is reverse). That is, the morning hand 4a moves to the symbol SYD of the area name display section 6, that is, Sydney, the afternoon hand 4b moves to a blank area on the east side of RIO, and the hour hand 2 and the minute hand 3 indicate 11:10. Now you know that Sydney is 11:10 AM.

Further, at this time, if the push button 8 is continuously pressed, the area pointer 4
Continues to rotate in reverse, but as shown in Fig. 2, Tokyo is 10 am
As shown in Fig. 2, at the time of 10 minutes, in the morning and afternoon, the morning and afternoon boundary line
It is divided into an area 11 in the morning and an area 12 in the afternoon on the boundary of 13. Therefore, when the morning hand 4a moves to Noumea (NOU) which is the next place name of Sydney (SYD), Noumea (NOU) becomes 12:10 am, which is different from the reality. Therefore, the AM hand 4a moves to an area with a time difference of 12 hours from Noumea (NOU) at 12:10 AM, and the afternoon hand 4b also moves to Noumea (NOU). From Noumea (NOU) to the afternoon hand 4b. However, the place name in the afternoon area 12 will be indicated. Similarly, the morning hand 4a is in the morning area 11
The place name in will be indicated.

The regional pointer drive means 91 is an OR 92, a regional hand drive circuit 93, and a second driven by an output signal from the regional hand drive circuit 93.
It consists of a motor 94.

Next, the operation of the circuit block diagram of FIG. 3 will be described. According to the timepiece specification of the present embodiment, when the push button 8 is pushed while the crown 7 is in the two-pulled state, the hour hand 2 and the minute hand 3 rotate forward,
Initialization correction for synchronizing the two counters 89, 90 of the hour / minute hand position detecting means 87 with the hour / minute hands 2, 3 is performed. When the push button 8 is pushed in the state of pulling the crown to the 1st position, the hour hand 2 and the minute hand 3 are rotated in the forward direction to correct the time, and the push button 9 is pushed to rotate the area indicating hand 4 in the forward direction. While paying attention to the afternoon, correct the time according to the symbol displayed on the area name display section. By pressing the push button 9 in the normal use state with the crown in the 0-step state,
Select a region and display the time in the selected region with a 12-hour system with hour and minute hands.

First, the initialization correction method will be described. From the switch circuit 53 with the crown pulled to the second stage,
When the first signal P60 is output, the correcting means 76 outputs the two-stage crown signal P58 which is one input signal of the OR77, so that the output signal of the OR77 which is one input signal of the AND78 is "H". AND78 is the other input signal, the first
The signal P60 is output from AND78. As a result, when the hour / minute correction signal generating circuit 80 is a one-shot signal for driving the minute hand 3 one time in the forward direction based on a predetermined frequency dividing signal P52 according to the timing of the first signal P60 from the AND78. The minute correction signal P80 is output, and the hour / minute correction signal P80 is supplied to the hour / minute hand driving means 82, whereby the minute hand 3 is set to 1 in the forward rotation direction.
While being driven, the hour hand 2 also rotates forward through the train wheel. On the other hand, the hour / minute correction signal P80 is also supplied to the hour / minute hand position detecting means 87, but the two counters of the hour / minute hand position detecting means 87 are reset by the crown two-stage signal P58. The counter number is not counted by the hour / minute correction signal P80. That is, by having the user perform the initialization correction to set the hour hand 2 and the minute hand 3 to 12:00 as an initial setting, the phases of the hour and minute hands and the hour / minute hand position detecting means 87 are correctly matched.

Further, in the 2-stage pulling state of the crown, the circuits of the time display means 64, the area changing means 67, the am / pm switching means 72 and the hour / minute hand position detecting means 87 do not operate at all.

 Next, a correction method for adjusting the time will be described.

When the crown is pulled to the 1st stage, the switch circuit 53
When the signal P60 is output, the correcting means 76 outputs the crown first stage signal P59 which is one of the input signals of the OR77, and thereafter the same as the time / minute correction signal P80 as in the case of the crown second stage pulling state. Based on the above, the minute hand 3 is driven once in the normal rotation direction, and the hour hand 2 also rotates forward by the train wheel from the minute hand 3. However, the two counters of the hour / minute hand position detecting means 87 are not reset, and the hour / minute correction signal P80 is supplied at the same time as the hour / minute hand driving means 82, so that the hand position of the minute hand 3 is advanced by 60. With counter 89, the position of hour hand 2 is a 12-digit counter
Remember at 90.

In other words, it is the same as storing the time digitally.
When the second signal P61 is output from the switch circuit 53 in the state where the crown is pulled to the first stage, the correcting means 76 outputs the crown first stage signal P59 which is one input signal of the OR77, and the AND79 is The second signal P61 is output. The area correction signal generating circuit 81 is a one-shot signal for driving the area indicating hand 4 one time in the forward rotation direction based on a predetermined frequency dividing signal P52 in accordance with the timing of the second signal P61 from the AND79. The correction signal P81 is output, and the area correction signal P81 is supplied to the area indicating needle drive means 91, whereby the area indicating needle 4 is
One shot is driven in the normal direction. In other words, by pressing the switch 57 for generating the second signal P61, that is, the push button 9, if the area at the adjusted time is in the morning, the am hand 4a is adjusted, and if the area is in the afternoon, the afternoon hand 4b is adjusted. Can be done. That is, by pressing the two push buttons 8 and 9 in the state of the crown in the first stage, the time can be adjusted while taking into consideration the time of the area to be adjusted whether it is morning or afternoon.

Further, in the crown one-step pulling state, the time display means 64, the area changing means 67, and the am / pm switching means 72 do not operate.

Next, the operation of the crown 0 stage state, that is, the normal use state will be described.

In the time display means 64, the inversion crown two-stage signal P62 and the inversion crown one-stage signal P63 from the switch circuit 53 are each at the “H” level in the 0-stage crown state, so the time signal generating circuit 66 follows the output of the AND65. Is the predetermined frequency division signal P5
Based on 2, the time signal P66 of 1 minute cycle is output, and the time signal P66 is supplied to the hour / minute hand driving means 82, whereby the minute hand 3 is set to 1
It is driven separately and the hour hand 2 also interlocks. Also, the time signal P66
Is also input to the hour / minute hand position detecting means 87, and the count number of the 60-base counter 89 is increased. That is, similarly to the time correction in the state of the first-stage crown, the 60-counter 89 stores the position of the minute hand 3 and the 12-counter 90 stores the position of the hour hand 2. Here, when the hour hand 2 is 12 o'clock, that is, when the time changes from am to pm or from pm to am, the signal P90 from the Q terminal of the 12-decimal counter 90 causes the am / pm switching means 72 to select the 12
A 12-detection circuit 73 that detects the count number of the advance counter 90 operates and outputs a one-pulse detection signal P73. The second and third inputs of AND74, the inverted crown second stage signal P62 and the inverted crown first stage signal P63, are each at the "H" level, so AND74
Outputs a detection signal P73. The 12-pulse generation circuit 75
According to the timing of the detection signal P73, to drive the area indicating hand 4 12 times in the reverse direction based on the predetermined frequency division signal P52
A 12-pulse signal P75 is output, and the signal P75 is supplied to the area indicating needle driving means 91, so that the area indicating needle 4 is rotated in the reverse direction.
Driven 12 times. In other words, by rotating the area indicator hand 4 180 ° in the reverse direction, the area indicated by the morning hand 4a changes to the hour hand 2 of 12
Point to the time, that is, the morning hand 4a
The area that was instructed by is to be instructed by the afternoon hand 4b, and it is not different from the time of the specified area.

Next, the relationship of the circuit operation for changing the designated area will be described.

When the push button 8 is pressed in the crown 0-step state, the area indicating hands 4a and 4b are rotated in the opposite direction and the hour hand 2 is advanced for one hour. Therefore, the first and second inputs of the AND68 in the area changing means 67 are performed. Inverted crown 2-stage signal P6 from the switch circuit 53 which is a signal
Since the 2 and inverted crown first-stage signal P63 are both at "H" level, the first signal P60 from the switch circuit 53, which is the third input signal, is output from the AND68. Region change signal generation circuit 71
Then, according to the timing of the first signal P60 from the AND68, the area change signal P71, which is a drive signal for driving the area indicating hand 4 once in the reverse direction, is output based on the predetermined frequency division signal P52. By supplying the P71 to the area indicating needle driving means 91, the area indicating needle 4 moves to the area on the east side of the area instructed. The 60-pulse generator circuit 70 is
The first signal P60 from D68 is considered as the one-hour advance signal 69 for advancing the time by one hour, and the minute hand 3 is rotated in the forward direction 60 in accordance with the predetermined frequency division signal P52 in accordance with the timing of the one-hour advance signal 69. A drive signal for starting and driving (that is, since the hour hand 2 is connected to the minute hand 3 by a train wheel, one complete rotation of the minute hand 3 in the forward direction means that the hour hand 2 advances by 1 hour). The start drive signal P70 is output, and the 60 start drive signal P70 is supplied to the hour / minute hand drive means 82, whereby the minute hand 3 rotates one revolution in the forward direction and the hour hand 2 advances for one hour. Further, since the 60 drive signal P70 is supplied to the hour / minute hand position detecting means 87, the two counters are set to 1
The positions of the hour hand 2 and the minute hand 3 that have advanced by the time are stored, that is, the decimal counter 90 increments the count number by one. At this time, 12
When the count number of the binary counter 90 becomes 12, and the 12 detection circuit 73 detects the number, the 12 detection circuit 73 outputs the 12 detection signal P73.
Is output and supplied to the 12-pulse generation circuit 75, which in turn rotates the area indicator needle 180 ° 180 ° based on a predetermined frequency division signal P52 according to the timing of the 12-detection signal P73. 12 pulse signal P75 is output.
The 12-pulse signal P75 is supplied to the area indicating needle driving means 91, so that the area indicating needle 4 rotates 180 ° in the reverse direction. In other words, this happens when the time shifts from the designated area to the eastern area when the time changes from morning to afternoon and from afternoon to morning. As explained in Figure 2, from Sydney (SYD) to Noumea ( NOU), when the time designated area is changed.

As described above, the world time can be represented by a 12-hour hand pointer type electronic timepiece by using two area indicating hands.

[Effect of device]

As is clear from the above description, according to the present invention, by providing the morning area indicator needle and the afternoon area indicator needle,
When displaying the world time on a pointer-type electronic timepiece, it is possible to display it in 12-hour time, even though it was displayed in 24-hour system, and it is the maximum that it can be used without any change from a clock that is commonly used. It is a feature.

In addition, the regional indicator hand in the morning and the regional indicator hand in the afternoon can greatly change from the conventional needles, so it is possible to indicate the region with a unique expression in terms of design,
The specified region is every 12 hours, that is, from morning to afternoon,
When changing from the afternoon to the morning, the two regional indicating hands are given a unique movement of changing hands, giving the effect of a pointer-type world clock that has never existed.
