Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer timepiece, and more particularly to a timer timepiece which a user can easily visually recognize while training or competing in a gymnasium, a ground or the like and can know the training time or the competition time.

[0002]

2. Description of the Related Art Conventionally, an analog display timepiece is known in which 60 display segments are arranged in a radial pattern similar to a hand-type analog timepiece, and these are selectively displayed to display the time (for example, Japanese Examined Patent Publication No. 63-149199). Issue). In the invention disclosed in this publication, in a conventional mechanical timepiece having a minute hand and a minute hand, it is mechanically complicated to display domestic time and foreign time with a time difference on the same time display unit, Since the timepiece body is large in both thickness and width, it is described that the timepiece body is made electronic by using a liquid crystal display element in order to make it small and thin. That is, this timepiece is intended for a wristwatch or a small timepiece used indoors.

On the other hand, the display is of a size that is installed on the floor or wall surface of an indoor stadium such as a gymnasium or pool, or on the ground of an outdoor stadium such as a ground so that a user such as an athlete can visually recognize it while training or competing. Hand-held analog timepieces with faces are known. Since this type of watch is viewed by the user from a considerable distance while training or playing a competition, its display surface is considerably large, for example, 90c so that the time can be easily read.
It is often set to a size of about m square.

[0004]

Since the above-mentioned stadium analog timepiece has a mechanical structure, it is limited to the "minute" display by the short hand and the "second" display by the long hand, and the training method, for example, the interval training time. A timer function for each setting and set time, a down-count timer function in addition to an up-count timer, a plurality of long hands or short hands are displayed simultaneously (for example, from 1 minute to 10 minutes), and a so-called graphic display that shows the time in a fan-shaped area Functions, etc. are impossible. On the other hand, in this kind of stadium analog timepiece, the electronic timepiece as shown in the above publication has not been realized yet. Since the display surface is large, the substrate is also large, and there is a problem in its plane accuracy, etc., and if it breaks down, it is necessary to replace the whole substrate, and there is also a problem that many normal elements etc. are wasted. It is difficult to realize.

The present invention has been made in order to solve such a problem, and particularly provides a timer clock useful when applied to a large-scale timer clock for stadiums.

Next, referring to FIGS. 6 to 8, the small substrate P
Regarding No. 1, display driving of the LED display element will be described.
FIG. 6 shows the small substrate P1, and 10 LED display element groups arranged in a radial pattern at equal intervals are formed on the small substrate P1. Nine LEDs are arrayed at equal intervals on one radiation, and the outer two on each radiation are the first display element group and the inner seven are the second display element group. Is configured. The display elements in the same display element group are turned on or off at the same time. The small substrate P1 includes ten first display element groups S0, S1, ... S9 and ten second display element groups U.
0, U1, ... U9 are located. In FIG. 6, the LEDs that are turned on are indicated by black dots, and the LEDs that are turned off
Are indicated by white dots. Therefore, in the case of the same figure, the first display element group S2 is in the lighting state, and the second display element groups U2 and U5 are in the lighting state.

The first and second display element groups S on the small substrate P1
0, S1, ... S9, U0, U1, ... U9 is 4 × 5
Are arranged on a matrix of 4 and are driven by four signals a1, b1, c1, d1 from the driver D1 and five signals e, f, g, h, i from the driver D7. In the figure, the LEDs indicated by symbols S0, S1, ... S9 are actually two LEDs, and the symbols U0,
The LEDs indicated by U1, ... U9 are actually 7 LEs.
It consists of D. The display element groups arranged on the other small substrates P2 to P6 also have the same structure, and the time signals from the corresponding drivers D2 to D6 and the common drive signal from the driver D7 are input. INV is driver D
On the output side of 7, a signal is inverted by an inverter provided on each of the small boards P1 to P6.

FIG. 8 shows an example of drive signals for the display element group.
This is a case where the timer time "5 minutes 02 seconds" is displayed in analog. In this case, the second display element group U5 corresponding to "5 minutes" from the driver D1 and the first and second display elements U2 corresponding to "2 seconds"
The display element groups S2 and U2 are selectively displayed, and the signals a1 and c1 are output in synchronization with the drive signal g and the signal d1 is output in synchronization with the drive signal e. Such a lighting display state is shown by a black dot in FIG. 6, which is an analog display, that is, the minute hand (second display element group) indicates “minute” and the long hand (first and second display element group).
"Second" is displayed at. When the above display is "hour / minute", it indicates "1: 2". In this way, the time display is dynamically driven at 1/5 duty for each of the small boards P1 to P6. The reason why the drive of each of the small substrates P1 to P6 is a 4 × 5 matrix is that the number of drive circuit elements is 1.
This is because the number of small substrates is 9, which is relatively small, and the display does not flicker because it is driven at 1/5 duty.

In the above structure, by combining the displays of the first and second display element groups S0, S1, ... S9, U0, U1, ... U9, graphic display according to training or competition is possible. Is. For example, in the above timer time display, "minutes" are displayed on the second display element group, and "seconds" are displayed on the cumulative display of the second display element group and the first display element group at the final stage. be able to. FIGS. 9A and 9B show a case where the timer time “15 minutes 40 seconds” is shown in two types of display forms,
(A) is an analog display and (b) is a graphic display. In this case as well, the LEDs that are turned on are indicated by black dots. And in the graphic display,
Only the second display element group corresponding to "15 minutes" blinks to indicate that "15 minutes". Switching between the analog display and the graphic display is performed by operating the "display switching" key.

As another example, the remaining time in the sucker competition will be described using a case where the downcount timer function unit is used and is graphically displayed. Simultaneously with the start of the game, the second display element groups U0, U1, ... U9 are turned off one by one counterclockwise from the all-lit state, and the "second" is displayed as a down count. At this time, in the second display element group, only the portion corresponding to "second" is turned on.
That is, the first display element group is turned on one by one in correspondence with "seconds", and the second display element group is turned off one by one for each accumulated display. In addition,
The "minute" display blinks only on the corresponding second display element group.

When a graphic display is used as an interval training timer, for example, when 5 minutes training, 3 minutes rest, 5 minutes training, 3 minutes rest are set, as in the above-mentioned example at each time, Time counts down. After 5 minutes, a buzzer sounds to notify the end of the training period, and then 3 minutes are displayed as a down count, and the same display is made thereafter. With such a configuration, the remaining time is quantitatively understood and the amount is decreasing, so that a sense of achievement of training can be strongly obtained as compared with the up-count display.

When used as an analog timepiece for displaying "hour and minute", for example, when trying to set "10:10", the "minute + 1" key is kept pressed to bring the second display element group to ". "10 o'clock", then press the "second +1" key 10
It is pushed twice to set the first and second display element groups to “10 minutes”. Then press the "Start Stop" key once.
In this way, the timing operation is started from the state of "10:10". If it is desired to add the "second" display to this, in the case of analog display, the first and second display element groups corresponding to the second hand may be turned on in units of seconds. It is also possible to switch to graphic display and cumulatively display the first display element group in units of seconds.

As described above, it can be used as a stopwatch function, an upcount timer, a downcount timer, an upcount program timer, a downcount program timer, and a clock. The stopwatch and timer functions can be up to 59 minutes 59 seconds. It is possible, and if it exceeds 1 hour, the counting continues from zero. Further, in both functions, both analog display and graphic display can be switched and displayed.

[0037]

According to the present invention (Claim 1), when the display elements arranged in a radial pattern are turned on in a manner similar to a short hand and a long hand, the display elements are accumulated as a conventional analog display timepiece. By displaying it, it can be used as a graphic display clock that represents the remaining time as an amount (area). Further, since it can be used not only as an up-count timer but also as a down-count timer, it can be used in various ways according to the purpose of use such as training or competition.

Further, according to the present invention, since the board is divided into a plurality of small boards having substantially the same shape, it is possible to replace the defective parts with a minimum of parts, and the display element can be replaced. Can be used effectively. In particular, when a large number of display elements are used as in the present invention, in order not to waste them, it is economically extremely effective to divide the substrate as described above. In addition, when the display surface is enlarged, the substrate also needs to have a large size, but not limited to the printed circuit board, a flat plate often has a problem of flatness when the size increases. In the present invention, since the substrate is divided into a plurality of small substrates, such flatness does not pose a problem, and the compatibility with other components becomes good. In addition, the same number of display element groups
Since it is divided into sets and each is driven independently for display,
The duty ratio of the display becomes smaller, and
You can suppress the glare. In addition, the drive signal generation side
Can be shared, so the total number of drive circuit elements
Can be reduced.

According to the present invention (claim 2), the display element groups arranged in a radial pattern are divided into two groups, that is, a first display element group located outside and a second display element group located inside. As a result, the time can be displayed as an amount (area) by the time display with the short hand and the long hand similar to an analog timepiece, and the cumulative display thereof. Therefore,
The time can be displayed easily for the user.

Further, according to the present invention (claim 3), by displaying the short hand and the long hand with the radial display element group, it is possible to display two types of time, "hour / minute" and "minute / second". Become. Further, these displays can be displayed graphically, and the "second" display can be added to the "hour / minute" display.

[0041]

Furthermore, according to the present invention (claim 4 ),
Since six sets of display element groups are formed on the six small substrates, each small substrate receives a common drive signal and is independently driven. Therefore, each of the small substrates can have substantially the same shape, the same number of display elements, and the same wiring pattern, and the compatibility is imparted to each other, and the replacement work for repair and the like can be simplified and the cost thereof can be kept low. .

Furthermore, according to the present invention (claim 5 ),
By fixing the small substrate to the display plate, the distance between the display element group and the display plate can be kept constant, and the lighted part of the display element will definitely appear on the display plate. There is no possibility that the brightness of the display element will be bright or dark due to an error, and the brightness can be kept constant on the front surface. Especially when there is a possibility that the display section is large as in the present invention, the error in the distance between the display plate and the substrate is likely to be large, but the substrate is divided as in the above structure, and this is directly used as the display plate. By fixing it, the error is minimized. Further, since the small board is not fixed to the frame portion, this does not cause the thickness of the timepiece to increase, and the thin structure can be maintained.

Further, according to the present invention (claim 6 ),
By constructing the display plate with a foamed material, the timepiece can be made lighter, and the flexibility of the foamed material can absorb dimensional errors that tend to occur when the watch is upsized.

Furthermore, according to the present invention (claim 7 ),
Since the LED is used as the display element, the time can be displayed brightly and easily, and even a user such as an athlete who concentrates on training or competition can know the time at a glance.

Furthermore, according to the present invention (claim 8 ),
It is possible to realize a timer clock that is installed in a wide area such as a gymnasium or a ground and can be easily visually recognized even from a considerable distance.
