Description

  The present invention relates to a pointer-type display device that indicates information by a pointer, and relates to a pointer-type display device that is used for a clock that indicates time and the like, a meter that indicates various measurement amounts, and the like.

  BACKGROUND ART A pointer type display device (analog type display device) that indicates information using a pointer is widely used in analog clocks, meters of various measuring instruments such as a thermometer, a barometer, and a speedometer. Such a pointer-type display device includes a pointer and a scale plate (a dial plate in a watch) arranged on the back of the pointer and displaying a scale.

As a display device having such a pointer, an information display device in which a dial is formed by a display device such as a liquid crystal display device is known (see Patent Document 1).
This information display device indicates the time by the hour hand and the minute hand, and displays additional display information by the display device. The information display device moves the information display position on the display device in accordance with the movement of the hour hand and the minute hand so that the hour hand and the minute hand do not overlap with the display information, thereby improving the visibility of the display information. Yes.

JP 2006-242717 A

  However, in the timepiece of Patent Document 1, as with a normal analog timepiece, numbers are displayed on the dial and the instructions of the hour hand and the minute hand are read, but in particular, the pointer is located between the numbers. In some cases, there is a problem that the legibility is lowered. In particular, in various measuring instruments, since it is necessary to read more accurate information, degradation of readability has been a problem.

  Further, in the timepiece of Patent Document 1, only the hour hand and the minute hand are provided. However, when the second hand is provided, the information display position is frequently moved, the legibility is lowered, and the display is frequently switched. However, there is a problem that power consumption increases. For this reason, for example, when the information display device is driven by a battery like a wristwatch, there is a problem that the battery life is shortened.

A first object of the present invention is to provide a pointer-type display device capable of improving the legibility of instructions by a pointer.
In addition to the first object, the second object of the present invention is to improve both the legibility of instructions by the pointer and the legibility of the information displayed on the display panel when information is displayed on the display panel. An object of the present invention is to provide a pointer-type display device that can be made to operate.
According to a third object of the present invention, in addition to the above object, in the case where an hour hand, a minute hand, and a second hand are provided as a pointer, both the readability of the instruction by the pointer and the readability of the information displayed on the display panel are both provided. An object of the present invention is to provide a pointer-type display device that can be improved.

  A pointer-type display device according to the present invention controls a pointer, a pointer moving means for moving the pointer, a display panel provided on the back of the pointer and capable of displaying an image, and driving of the pointer moving means and the display panel Drive control means, and the drive control means includes scale display control means for displaying a scale in a scale display area that overlaps the movable area of the pointer on the display panel, and a pointer for detecting the position of the pointer The scale display control means includes a position detection means and an information display means, and the scale display control means converts the scale display area into an index area and a non-index other than the index area based on the pointer position detected by the pointer position detection means. A scale for reading the indicated value of the pointer is displayed only in the index area, and the information display means is configured to display the non-index. And displaying the information on the source region.

Here, as the pointer moving means for moving the pointer, for example, one provided with a driving means such as a stepping motor and a train wheel rotated by the driving means can be used. However, the pointer moving means is not limited to the one that rotates the pointer, but may be one that linearly slides the pointer.
As the display panel, for example, various display devices such as a liquid crystal display, an organic EL (electroluminescence) display, and an EPD (Electrophoretic Display) can be used. The display panel may be a segment drive type in the case of displaying only the scales for the hands and the numbers. However, if a matrix-driven display panel is used, not only the scale but also information such as characters and numbers can be freely displayed.
Further, the scale display area that overlaps the movable area of the pointer on the display panel in a plane is formed by including the projection area when the area where the pointer can move is projected onto the surface of the display panel. Means that. Normally, the scale display area is set to have substantially the same shape and size as the pointer movable area.

According to the present invention, in a pointer-type display device including a pointer and a display panel, an index area is set in the scale display area according to the position of the pointer, and an indication value of the pointer is read in the index area. Since the scale is displayed, the scale corresponding to the current pointer position can be displayed. In particular, since the index area is set according to the position of each pointer, for example, even when a pointer with a different length dimension is provided, such as an hour hand and a minute hand of a clock, it corresponds to the length dimension of each pointer. The scale for each pointer can be set. For this reason, the scale can be displayed at a position where the indication of the pointer is easy to read, such as a position where the tip of the pointer overlaps with the pointer, and the readability of the pointer can be improved, thereby achieving the first object.
Further, since the scale is displayed only in the index area, the scale is not displayed in the non-index area. Therefore, the information display means can display various information using the area. For this reason, compared to the case where the scale is displayed in a circle as in a normal watch, the scale display area is reduced, and a larger non-index area can be secured accordingly. It is also easy to display various information at positions that do not overlap. Therefore, it is possible to improve both the legibility of the instruction by the pointer and the legibility of the information displayed on the display panel, and the second object can be achieved.
For example, when the pointer is driven to rotate, the index area may be set in a band shape curved at the tip portion of the pointer, that is, in an arc shape, and a non-index area may be set inside the index area. In this case, since a part of the non-index area is overlapped with a part on the rotating shaft side of the pointer, the information display unit may display information in an area where the pointer does not overlap in the non-index area.

Here, the non-index area is also provided on the outer peripheral side of the scale display area on the display panel, and the information display means displays information also on the non-index area provided on the outer peripheral side of the index area. It is preferable.
In addition, when the pointer type display device is a timepiece, it is preferable that the information includes characters and pictures related to time. For example, as the information, it is possible to use information that displays a schedule content in characters or displays a schedule time in a band shape.

The pointer is generally of a type that rotates in one direction around the rotation axis, such as an hour, minute, second hand of a watch, or a type that rotates around the rotation axis, such as a speedometer of an automobile. The movable area of these pointers, that is, the scale display area, has a circular or fan-shaped planar shape.
On the other hand, the display panel usually has a rectangular display area. For this reason, the display panel also has a display area outside the scale display area. In the present embodiment, the area on the outer peripheral side of the scale display area is set as a non-index area, and information is displayed by the information display means, so that the area where information can be displayed can be increased.
Further, since the non-index area is set outside the scale display area, the information display means can also display information in the extending direction of the pointer on the display panel. For this reason, information related to time, such as schedule information, can be displayed adjacent to the scale portion of the time, and the readability of the information can be further improved.

The pointer is attached to a rotation shaft rotated by the pointer moving means, the scale display area is formed in a circle centered on the rotation axis of the pointer, and the index area is in the scale display area. It is preferable that the fan is formed in a fan shape connecting the arc on the outer periphery of the scale display area and the center of the circle.
According to the present invention, in the pointer type display device in which the pointer is rotated like the hour hand and the minute hand of the timepiece, the scale can be displayed along the movement locus of the tip of each pointer. Can be improved.

At this time, it is preferable that the index area has a central angle set in a range of 30 degrees to 270 degrees.
When the central angle is less than 30 degrees, the number of scales that can be displayed is reduced, and the readability of the pointer is reduced as compared with the case where the central angle is 30 degrees or more. Further, when the central angle is larger than 270 degrees, the area of the non-index area becomes small, and when various information is displayed in the non-index area, the display area becomes small, and the central angle is 270 degrees or less. Compared with, the readability of displayed information is lowered.
On the other hand, if the sector-shaped index area is set within a range of 30 degrees to 270 degrees, the scale can be displayed at least so that the pointer moves by 30 degrees, so that the scale of the pointer can be sufficiently read. In addition, the area of the non-index area can be secured, and the legibility of information displayed in the area can be improved.

Furthermore, it is preferable that the pointer is configured to include two or three pointers whose rotation axes are coaxial, and the index region is set to have a central angle in a range of 30 degrees to 90 degrees.
When the central angle is less than 30 degrees, the number of scales that can be displayed for each pointer is reduced, and the legibility of the pointer is reduced as compared with the case where the central angle is 30 degrees or more. Also, if the central angle of the index area of each pointer is greater than 90 degrees, the index area is set for each pointer, so that the information display area is greatly reduced and the legibility is also reduced.
On the other hand, if the sector-shaped index area is set in the range of 30 degrees to 90 degrees, the scale can be displayed at least for the pointer to move by 30 degrees, so that the scale of the pointer can be sufficiently read. In addition, even when two to three pointers are provided, the area of the non-index area can be secured, and the legibility of information displayed in the area can be improved.

  In the pointer type display device of the present invention, the display panel is configured by a display element having a memory property, and the drive control means performs a compensation operation for compensating display degradation of the display panel for predetermined display degradation compensation. The scale display control means is executed at an operation interval, and the scale display control means is a predetermined amount that is set according to the display degradation compensation operation interval in the movement direction of the pointer at the same interval as the display degradation compensation operation interval. It is preferable to move.

Here, the memory-type display element is an element that can continue display for a predetermined time without continuing the power supply. For example, an electrophoretic display device such as an EPD (Electrophoretic Display) called a so-called electronic paper is used. Available.
The memory-type display element can continue the display for a predetermined time without continuing the power supply, but the contrast gradually decreases. For this reason, even when the display content is not changed, the display contrast can be improved by supplying power when a predetermined time has elapsed. A driving operation for supplying power in order to compensate for such display deterioration is called a compensating operation. Therefore, the display degradation compensation operation interval may be set according to the type of display element, the driving method, and the like.

If a memory display element is used for the display panel, the power consumption for maintaining the display can be greatly reduced, and in particular, the battery life can be extended and the operable time can be extended in a portable timing device such as a wristwatch. Battery replacement and charging can be reduced, and convenience can be improved.
In addition, since the memory-type display element consumes power when the display is updated, the power consumption can be reduced by increasing the display update interval. Therefore, if the update interval of the scale display or information display is lengthened, power consumption can be reduced accordingly.

Further, since the scale display control means performs the index region update operation at the same interval as the display degradation compensation operation interval, the index region update operation and the display degradation compensation operation can be performed at the same timing. . For this reason, compared with the case where each operation | movement is performed at a separate timing, the frequency | count of an electric power supply can be reduced and the part | minute can save power.
Further, since the index area is moved by a predetermined amount set according to the display deterioration compensation operation interval, for example, the index area is moved in accordance with the movement amount of the pointer moving at the display deterioration compensation operation interval. The scale can always be displayed at the position of the pointer. For example, when the display deterioration compensation operation interval is 15 minutes, the pointer and the scale can always be displayed in conjunction with each other by moving the index area by the amount that each pointer moves in 15 minutes.

  Here, the pointer type display device includes a time measuring unit for measuring time, the pointer is configured to include an hour hand and a minute hand, and the drive control unit is configured to display the pointer based on time information measured by the time measuring unit. The movement means is controlled to move the hour hand and the minute hand, and the scale display control means sets an hour hand index area corresponding to the hour hand and a minute hand index area corresponding to the minute hand, and displays a scale in each index area. The drive control means preferably switches the display deterioration compensation operation interval based on the time of the time measuring means.

With the pointer type display device (clock) having such a configuration, the readability of the hour / minute time indication can be improved, and various information such as date information, day of the week information, world time, etc. in the non-index area The various information can be displayed and the legibility of this information can be improved.
Therefore, the clock of the present invention has the advantage of an analog clock that the time can be intuitively interpreted by the hands, and the advantage of a digital clock that can display various information such as date, day of the week, and world time, and It is possible to improve the legibility of each instruction / information and to make the watch more convenient.
Furthermore, since the display panel can also be used as a timepiece dial, the thickness of the timepiece can be reduced and the timepiece can be made thinner.

In addition, since the display degradation compensation operation interval can be switched based on the time of the time measuring means, the length of the display degradation compensation operation interval can be controlled according to the user's usage mode, thereby further saving power. Can be achieved.
In the case of a wristwatch, it is often removed from the user's arm and not used at night (for example, from 11 pm to 7 am). For this reason, since there is no problem even if the contrast of the scale display is slightly lowered at night, the display deterioration compensation operation interval is made longer than that in the daytime, thereby reducing power consumption.

  The index area may be set so that at least a scale corresponding to the amount of movement of the pointer at the display deterioration compensation operation interval can be displayed. For example, when the display deterioration compensation operation interval is set to 15 minutes in the daytime and 30 minutes in the nighttime, the daytime minute hand index area is large enough to display a scale of at least 15 minutes (for example, the central angle is 90 °). Index area). On the other hand, it is preferable that the index area for the minute hand at night is sized to display a scale of at least 30 minutes (for example, an index area having a central angle of 180 degrees or more).

Preferably, the scale display control means moves the index area in the moving direction of the pointer by the predetermined scale when the pointer moves by a predetermined scale.
The predetermined scale may be one scale or two or more scales. In particular, when the pointer-type display device is a watch, the scale for the minute hand is preferably about 4 to 30 scales, and most preferably the scale corresponding to the display deterioration compensation operation interval.
According to the present invention, since the scale display is switched in conjunction with the movement of the pointer, for example, the pointer can always be positioned at the center of the displayed scale range. For this reason, there is an advantage that the instruction of the pointer can be roughly read by the displayed scale, and the instruction of the pointer can be easily grasped intuitively. In particular, even when the movement of the pointer cannot be estimated as in the case of meters of various measuring instruments, the position of the pointer can be grasped from the scale, and the instruction of the pointer can be easily grasped.

The scale display control means preferably moves the index area by a predetermined distance in the movement direction of the pointer when the pointer moves to the end of the index area.
According to the present invention, since the index area is moved every time the pointer moves to the end of the index area, the same scale display can be maintained until the pointer moves to the end of the index area. The frequency of setting switching, that is, the update of the scale display can be reduced.
Therefore, when a display element having a memory property such as EPD is used as the display panel, the display update frequency can be reduced and the power consumption can be reduced.
For this reason, in particular, when applied to a thermometer with a small movement amount of the pointer or a watch having a constant movement of the pointer, the display update frequency can be reduced and the power consumption can be reduced.

It is preferable that the scale display control means moves the index area by a predetermined distance in the movement direction of the pointer at regular time intervals.
According to the present invention, if the pointer moves at a constant speed, such as a timepiece pointer, the movement of the pointer can be surely followed by moving the index area at regular time intervals. And, by setting this time interval, the display frequency of the scale display can be reduced. Therefore, especially when a display element having a memory property such as EPD is used as the display panel, the display update frequency can be reduced and consumed. Electric power can be reduced.

  The pointer-type display device of the present invention includes a time measuring means for measuring time, the pointer is configured to include an hour hand and a minute hand, and the drive control means moves the pointer based on time information timed by the time measuring means. The hour and minute hands are moved by controlling the means, and the scale display control means sets an hour hand index area corresponding to the hour hand and a minute hand index area corresponding to the minute hand, and displays a scale in each index area. A so-called watch is preferable.

With the pointer type display device (clock) having such a configuration, the readability of the hour / minute time indication can be improved, and various information such as date information, day of the week information, world time, etc. in the non-index area The various information can be displayed and the legibility of this information can be improved.
Therefore, the clock of the present invention has the advantage of an analog clock that the time can be intuitively interpreted by the hands, and the advantage of a digital clock that can display various information such as date, day of the week, and world time, and It is possible to improve the legibility of each instruction / information and to make the watch more convenient.
Furthermore, since the display panel can also be used as a timepiece dial, the thickness of the timepiece can be reduced and the timepiece can be made thinner.

Here, the scale display control means preferably displays the scale displayed in the hour hand index area in an area inside the scale displayed in the minute hand index area.
Since the hour hand is shorter than the minute hand, the tip of the hour hand is arranged away from the dial of the dial in a normal timepiece. On the other hand, in the present invention, since the hour hand scale is displayed in the inner area of the minute hand scale, the hour hand scale can be displayed near the hour hand, and the readability of the hour hand instruction can be further improved.

The scale display control means continuously sets the hour hand index area and the minute hand index area when the angle formed by the hour hand and the minute hand detected by the pointer position detecting means is equal to or smaller than a predetermined angle. The scale of each index area is displayed at a position equidistant from the rotation axis of the pointer, and when the angle formed by the hour hand and the minute hand detected by the pointer position detecting means is larger than a predetermined angle, The scale displayed in the index area is preferably displayed in an area inside the scale displayed in the minute hand index area.
When the angle between the hour hand and the minute hand is a predetermined angle, for example, 90 degrees or less, if each index area is made continuous and a scale for each pointer is continuously provided, the frequency of updating the scale can be reduced, and power consumption can be reduced. It can be further reduced.

Here, the pointer includes a second hand, and the drive control unit controls the pointer moving unit based on time information measured by the time measuring unit to move the hour hand, the minute hand, and the second hand, and the scale display control unit Preferably, a second hand index area corresponding to the second hand is set, and a scale displayed in the second hand index area is displayed in an area inside the scale displayed in the hour hand index area.
According to such a configuration, the hour, minute, and second hands can be used to indicate the hour, minute, and second time, and the user can intuitively grasp the second of the current time using the pointer. Further, since the scale for the second hand is displayed inside the scale for the hour hand, it is possible to prevent the scale display for the second hand from affecting the information display in the non-index area.
If the length of the second hand is shorter than that of the hour and minute hands, the possibility that the second hand will overlap the information displayed in the non-index area can be reduced, and the information readability can be prevented from degrading. .

The pointer includes a second hand, and the drive control unit controls the pointer moving unit based on the time information measured by the time measuring unit to move the hour hand, the minute hand, and the second hand, and the scale display control unit includes A circular second hand scale display area for displaying a scale corresponding to the second hand is set, and the scale displayed in the second hand scale display area is displayed in an area inside the scale displayed in the hour hand index area. It is preferable.
Even in such a configuration, the hour, minute, and second hands can be used to indicate the hour, minute, and second time, and the user can intuitively grasp the second of the current time using the pointer. Further, since the scale for the second hand is displayed inside the scale for the hour hand, it is possible to prevent the scale display for the second hand from affecting the information display in the non-index area. Furthermore, since the scale for the second hand is displayed in the range of 360 degrees along the outer periphery of the scale display area for the second hand, the display update frequency can be reduced as compared with the case of switching the scale for the second hand, Power consumption can be reduced.
If the length of the second hand is shorter than that of the hour and minute hands, the possibility that the second hand will overlap the information displayed in the non-index area can be reduced, and the information readability can be prevented from degrading. .

Further, the pointer includes a second hand, and the second hand has a length dimension from the rotation axis of the second hand to the tip of the second hand that is greater than or equal to a length dimension from the rotation axis of the minute hand to the tip of the minute hand, and the scale display control means includes: It is preferable to display the scale for the hour hand and the minute hand without displaying the scale corresponding to the second hand.
A typical timepiece second hand is formed with approximately the same length as the minute hand. The second hand is formed thinner than other hour and minute hands. When such a second hand is provided, the movable area of the second hand includes the scale display area for the minute hand and hour hand. Therefore, when the scale for the second hand is displayed, the index display area for the minute hand and hour hand is not indexed. There is a risk of overlapping the information displayed in the area in a planar manner.
On the other hand, in the present invention, since the scale for the second hand is not displayed, the information displayed in the non-index area does not overlap the scale for the second hand, and it is possible to prevent the readability of the information from deteriorating. .
In the present invention, the second hand may overlap the information displayed in the non-index area. However, the second hand moves faster than the minute hand, and even if the second hand overlaps the display information, the display information is displayed several seconds later. Therefore, the readability of the information displayed in the non-index area does not deteriorate.

The display panel is preferably composed of a display element having a memory property.
The memory-type display element is an element capable of continuing display for a predetermined time without continuing power supply. For example, an electrophoretic display device such as an EPD (Electrophoretic Display) called so-called electronic paper can be used.

If a memory display element is used for the display panel, the power consumption for maintaining the display can be greatly reduced, and in particular, the battery life can be extended and the operable time can be extended in a portable timing device such as a wristwatch. Battery replacement and charging can be reduced, and convenience can be improved.
In addition, since the memory-type display element consumes power when the display is updated, the power consumption can be reduced by increasing the display update interval. Therefore, if the update interval of the scale display or information display is lengthened, power consumption can be reduced accordingly.

Moreover, it is preferable that the scale displayed in the index area includes an index indicating the position of the pointer and an arc-shaped connection line connecting the indexes.
If each index is connected by an arc-shaped connection line, the visibility of each scale can be improved.

Furthermore, it is preferable that the scale display control means displays a part of the scale with at least one of color or thickness different from that of other parts of the scale.
At this time, it is particularly preferable to display a part of the scale set based on the indicated position of the pointer with a color or thickness different from that of the other part of the scale. For example, as a scale for the minute hand, when a scale is displayed from 0 to 20 minutes and the minute hand indicates 12 minutes, an index indicating 10 to 15 minutes as a part of the scale, or these What is necessary is just to make the color and thickness of the connecting line which connects an index differ from other scale parts (the part which shows 0 to 9 minutes and 16 to 20 minutes).
Note that “different colors” means that at least one of hue, luminance, and saturation is made different so that a color difference can be identified.

If the color and thickness of a part of the scale are different from those of other parts, for example, it can be displayed with meaning to the transition of time. For example, if you distinguish 1 hour (60 minutes) every 15 minutes and change the color and thickness of the scale every 15 minutes, you can easily determine which area the current time zone is, You can also check progress such as elapsed time and remaining time.
In addition, if the scale color and thickness are set in relation to the schedule and the like, there is an advantage that the contents of the schedule can be grasped only by the color and thickness of the scale.
Furthermore, if the scale color and thickness are changed in accordance with the current position of the pointer, the current time can be grasped only by the scale.

Further, it is preferable that the scale display control means displays at least a part of the color of the index area different from the color of the non-index area.
At this time, when hour / minute index areas are set, the color may be changed for each index area.

If the color of the index area is different from the color of the non-index area, the index area can be easily grasped, and the position of the current pointer, for example, the approximate time can be easily grasped if it is a clock.
Also, the color of the index area can be set so that the pointer is conspicuous, and the visibility of the pointer can be improved.
Further, if the hour and minute index areas are made different in color, the positions of the hour hand and the minute hand can be easily grasped, and the approximate time can be grasped more easily.

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

That is, the crown 451 and the buttons 452 and 453 are arranged on the side surface of the watch body 10 as shown in FIG. Note that the position and number of the crowns 451 and the buttons 452 and 453 are not limited to those shown in FIG. 1 and may be provided at positions that can be operated by the user depending on the shape of the watch body 10 and the like. That's fine.

[Configuration of control circuit]
The control circuit 41 includes a pulse synthesis circuit 411, a drive control circuit unit 412, an analog display unit drive circuit 413 that controls movement of the pointer, and a display panel drive circuit 414 that controls display on the display panel 20. Has been.
The pulse synthesis circuit 411 divides the pulse signal output from the oscillation circuit 43 and outputs a predetermined reference signal (usually a 1 Hz pulse signal) to the drive control circuit unit 412.

The drive control circuit unit 412 includes a time counter 415 and a pointer position detection unit 416.
The time counter 415 stores calendar information such as date and time, and time information such as hour, minute, second, and the like. These values can be corrected by the external input device 45 and the reference from the pulse synthesizing circuit 411. It is configured to be sequentially updated by a signal. For example, the time counter 415 includes an hour counter, a minute counter, a second counter, a day counter, a month counter, and a year counter. When a 1 Hz reference signal is input from the pulse synthesis circuit 411, the drive control circuit unit 412 updates the second counter. When the second counter reaches 60 seconds, the minute counter is advanced by 1 minute, and the minute counter is 60 minutes. Then, the hour counter is advanced by 1 hour, so that the current time can be stored and updated.
Further, the drive control circuit unit 412 updates the day counter by one day when the hour counter reaches 24 hours, and updates the month counter by one month when the day counter is updated from the last day of the month. The month and date can also be updated.
Therefore, the oscillation circuit 43, the pulse synthesizing circuit 411, and the time counter 415 constitute time measuring means for measuring time.

The hand position detection means 416 detects the positions of the hour hand 31 and the minute hand 32 from the information of the hour counter and minute counter of the time counter 415. That is, since the hour hand 31 and the minute hand 32 are moved in conjunction with the counter value of the time counter 415, the pointer position detecting means 416 indirectly positions the hour hand 31 and the minute hand 32 based on the counter value of the time counter 415. Is detected.
In addition, when the positions of the hour hand 31 and the minute hand 32 are detected by the time counter 415, it is assumed that the counter value of the time counter 415 matches the indicated value of each hour hand 31 and minute hand 32. Therefore, the user may reset the time counter 415 to 0:00 and perform the time setting operation by performing a predetermined input operation in a state where the hour hand 31 and the minute hand 32 are set to 0: 0 in advance. In addition, a sensor is provided for detecting that the hour hand 31 and the minute hand 32 have moved to the position of 0: 0, and the counter value of the time counter 415 is reset to 0: 0 in accordance with the output of the sensor to adjust the time. It may be done automatically.

The drive control circuit unit 412 outputs drive control signals CS1, CS2, and CS3 to the analog display unit drive circuit 413 and the display panel drive circuit 414 based on the information of the time counter 415, respectively.
The drive control signal CS1 output to the analog display unit drive circuit 413 is a pulse signal output at 1 minute intervals in response to the update of the minute information of the time counter 415.

The drive control signal CS2 output to the display panel drive circuit 414 is information for displaying the scales 21 and 22 for the hour hand 31 and the minute hand 32 on the display panel 20, and specifically, a pointer. This is information indicating the positions of the hour hand 31 and the minute hand 32 detected by the position detecting means 416.
On the other hand, the drive control signal CS3 output to the display panel drive circuit 414 is time information displayed on the display panel 20, and is a signal indicating a number indicating “year / month / day” in the present embodiment.

  When the drive control signal CS <b> 1 is input from the drive control circuit unit 412, the analog display unit drive circuit 413 outputs a drive pulse to the stepping motor 46. That is, the analog display unit driving circuit 413 moves the minute hand 32 by driving the stepping motor 46 by the driving pulse. The hour hand 31 is moved in conjunction with the driving of the stepping motor 46.

  The display panel drive circuit 414 includes scale display control means 414A that controls display of scales (indexes) on the display panel 20, and information display control means 414B that controls display of various types of information on the display panel 20. ing.

[Scale display control]
When the scale display control means 414A detects the current positions of the hour hand 31 and the minute hand 32 by the drive control signal CS2 input from the drive control circuit section 412, the scale display control means 414A displays the hour hand index area 23 and the minute hand index area 24 according to the positions. The scales 21 and 22 for reading the indicated values of the hour hand 31 and the minute hand 32 are displayed in the index areas 23 and 24, respectively.
Specifically, the scale display control means 414A sets the scale display areas 25 and 26 that overlap the movable areas of the hour hand 31 and the minute hand 32 on the display panel 20, as shown in FIG. The scales 21 and 22 can be displayed in these areas 25 and 26, respectively.
Each of the scales 21 and 22 includes an index provided at regular intervals in the circumferential direction to indicate the positions of the hour hand 31 and the minute hand 32, and an arc-shaped connection line that connects the indexes.
In addition, the index of the scale 21 with respect to the hour hand 31 is provided at intervals of 30 degrees in every hour, that is, in the circumferential direction, and the index of the scale 22 with respect to the minute hand 32 is provided at intervals of 6 degrees in every minute, that is, in the circumferential direction. Yes.

In the present embodiment, the hour hand scale display area 25 is a rotation locus area of the hour hand 31 when the hour hand 31 is rotated 360 degrees (an inner surface area of a circle with the rotation axis of the hour hand 31 as the center and the tip of the hour hand 31 as the outer periphery). ) And a slightly larger circular area.
Similarly, the minute hand scale display area 26 is also a circular area slightly larger than the rotation locus area of the minute hand 32 when the minute hand 32 is rotated 360 degrees.

Then, the scale display control means 414A sets the hour hand index area 23 in the scale display area 25 according to the detected position of the hour hand 31, and in the scale display area 26 according to the detected position of the minute hand 32. The minute hand index area 24 is set.
The hour hand index area 23 is surrounded by an arc along the outer periphery of the scale display area 25 and a line segment connecting both ends of the arc and the center of the rotation axis of the hour hand 31 (radius of the circular scale display area 25). This is a fan-shaped area. Here, the central angle θ1 of the hour hand index region 23 is set to be not less than 30 degrees and not more than 270 degrees, and is set to about 90 degrees in FIG. In the timepiece, scales representing 1 to 12:00 are arranged at intervals of 30 degrees (360 degrees / 12). Therefore, in the present embodiment, the hour hand index region 23 is set so that the central angle θ1 is about 90 degrees and the four scales 21 can be displayed.

  The minute hand index area 24 is surrounded by an arc along the outer periphery of the scale display area 26 and a line segment connecting both ends of the arc and the center of the rotation axis of the minute hand 32 (radius of the circular scale display area 26). This is a fan-shaped area. Here, the central angle θ2 of the minute hand index region 24 is also set to 30 degrees or more and 270 degrees or less, and is set to about 120 degrees in FIG. In the timepiece, scales representing 1 to 60 minutes are arranged at intervals of 6 degrees (360 degrees / 60). Therefore, in the present embodiment, the minute hand index region 24 is set so that the center angle θ2 is about 120 degrees and 21 scales 22 can be displayed.

  Here, the scale display control means 414A sets the index areas 23 and 24 according to the position of the hour hand 31 and the minute hand 32 when the hour hand 31 and the minute hand 32 are moving. In the present embodiment, specifically, the following processing is performed. That is, when the hour hand 31 and the minute hand 32 move to the boundary position (end) between the index areas 23 and 24, the scale display control means 414A moves the index areas 23 and 24 in the moving direction of the hour hand 31 and the minute hand 32. Moved away. In the present embodiment, the hour hand index area 23 is rotated by an angle of 90 degrees in the direction of movement of the pointer, and the minute hand index area 24 is rotated by an angle of 120 degrees in the direction of movement of the pointer. , 24.

For example, in FIG. 4, when the hour hand 31 moves to the scale 21 at the 12 o'clock position, the scale display control means 414A moves the area from the scale 21 at the 12 o'clock position to the scale 21 at the 3 o'clock position as the hour hand index area 23. Set to.
That is, since four scales 21 for the hour hand 31 are displayed in the hour hand index area 23, when changing the setting to the next hour hand index area 23, the other scale 21 of the scales 21. The hour hand index area 23 is set with reference to the scale 21 positioned in the most clockwise direction. That is, the hour hand index area 23 is set to move every 90 degrees as the hour hand 31 moves. Therefore, the display update interval of the scale 21 is about 3 hours.

On the other hand, when the minute hand 32 moves to the scale 22 at the 20-minute position in FIG. 4, the scale display control means 414A sets the area from the scale 22 at the 20-minute position to the scale 22 at the 40-minute position as the index area 24 for the minute hand. To do.
That is, the scale 22 for the minute hand 32 is set to move every 120 degrees as the minute hand 32 moves. Therefore, the display update interval of the scale 22 is 20 minutes.
Note that the display panel drive circuit 414 performs a compensation operation for compensating for display degradation of the display panel 20 at a predetermined display degradation compensation operation interval. In the present embodiment, this display deterioration compensation operation interval is set to 20 minutes, and is set to the same interval as the display update interval of the scale 22. The scale 22 is moved by a predetermined amount set according to the display degradation compensation operation interval, specifically, an angle of 120 degrees which is a scale range of 20 minutes.

  Further, the scale display control means 414A sets the areas other than the index areas 23 and 24 as non-index areas in the scale display areas 25 and 26, and the scales 21 and 22 are not displayed. In the rectangular display area of the display panel 20, the areas on the outer peripheral side of the scale display areas 25 and 26 are also set as non-index areas. That is, in the display area of the display panel 20, all areas other than the index areas 23 and 24 are set as non-index areas.

  The display panel drive circuit 414 controls the drive of the display panel 20 by the drive control signal CS3 input from the drive control circuit unit 412 and displays predetermined information 200. 1 and 4, date information that is the current “year / month / day” is displayed. Therefore, the display panel drive circuit 414 updates the display of date information on the display panel 20 at intervals of one day. The information display content can be switched to other information by operating, for example, the crown 451 or the buttons 452 and 453. For example, information displayed on the display panel 20 by a button operation or the like includes various information such as day of the week information, current time (hour / minute / second) display, city name of other city (time zone), and world time information including local time. The time information can be switched and displayed. Further, when the combination watch 1 has a PDA (personal digital assistant) function, various information such as schedule information, Todo (work list) information, and address information may be displayed on the display panel 20.

Further, the information display control means 414B of the display panel drive circuit 414 displays the information 200 on the hour hand 31 and the minute hand 32 by displaying the information in an area other than the index areas 23 and 24 when displaying the information. Control is done so that they do not overlap.
For example, as shown in FIGS. 1 and 4, when the index regions 23 and 24 are provided in the upper half of the display panel 20, the information display control unit 414 </ b> B stores the information 200 in the lower half of the display panel 20. indicate.
On the other hand, as shown in FIG. 5, when the index regions 23 and 24 are provided in the lower half of the display panel 20, the information display control unit 414 </ b> B displays the information 200 on the upper half of the display panel 20. .
That is, the information display control means 414B displays the information 200 on the display panel 20 by appropriately adjusting the position and size of the information 200 according to the positions of the index areas 23 and 24.

In this embodiment, the following effects can be obtained.
(1) Since the scale display control means 414A is provided, the index areas 23 and 24 for the hour hand 31 and the minute hand 32 are set, and the scales 21 and 22 are displayed in the index areas 23 and 24. The scales 21 and 22 can be displayed in accordance with the current position of the minute hand 32. Therefore, the scales 21 and 22 can be displayed near the tips of the hour hand 31 and the minute hand 32, and the readability of the instructions of the hands 31 and 32 can be improved. In particular, in the combination timepiece 1 of the present embodiment, the scale 22 can be displayed near the tip of the hour hand 31, so that the indication of the hands 31 and 32 can be indicated as compared with a normal timepiece in which the scale is displayed away from the tip of the hour hand. The legibility can be improved.

(2) Since the scales 21 and 22 are displayed only in the index areas 23 and 24 by the scale display control means 414A, a wide area for displaying the information 200 can be secured by the information display control means 414B. That is, when the scales 21 and 22 are displayed in the entire area of the scale display areas 25 and 26, the display panel 20 has almost no area for displaying the information 200. On the other hand, in this embodiment, since the scales 21 and 22 are displayed only in the index areas 23 and 24, the information 200 is also displayed in the non-index areas of the scale display areas 25 and 26 as shown in FIG. can do. For this reason, the information 200 can be displayed using a wide area and can be displayed in a large size, so that the readability of the information can be improved.
In addition, since the information 200 is displayed in the non-index area, it is possible to reliably prevent the hour hand 31 and the minute hand 32 from overlapping the display information. For this reason, the information 200 is not hidden by the pointers 31 and 32, and the legibility of the information can be improved in this respect.
Furthermore, since the information 200 is displayed on the display panel 20 by the scale display control means 414A, the display area of the display panel 20 can be used effectively, and various information can be transmitted to the user.

(3) Since the display panel 20 is composed of a display panel having memory properties such as EPD, power consumption can be reduced and battery life can be extended. In particular, in this embodiment, the scale 22 for the minute hand 32 is updated at intervals of about 20 minutes. Further, the display of the scale 21 for the hour hand 31 is updated at intervals of about 3 hours.
Therefore, since the information display control means 414B only needs to control the scale display every 20 minutes even at the minimum interval, for example, the information display control means 414B has a display update frequency compared with the case where it is updated at 1 minute intervals in conjunction with the movement of the minute hand 32. The power consumption can be reduced accordingly.
In addition, since the update interval of the scale 22 is set to the same interval as the display deterioration compensation operation interval of the display panel 20, the number of times of power supply can be reduced compared to the case where each operation is performed at different timings. Thus, power saving can be achieved.

(4) Since the display panel 20 also serves as a dial, the timepiece 1 can be made thinner than when the dial is stacked on the display panel 20. Furthermore, by controlling the display on the display panel 20, it is possible to freely set dials of various designs, so that the design of the combination timepiece 1 can be further improved.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. Note that, in each embodiment described below, the same or similar components as those in the above-described embodiments are denoted by the same reference numerals, and description thereof is omitted or simplified.
As shown in FIG. 6, the combination timepiece 1B of the second embodiment is provided with a second hand 33 in addition to the combination timepiece 1 of the first embodiment, and a scale 27 for the second hand 33 is displayed on the display panel 20. The main difference is that the other configurations are almost the same. That is, the combination clock 1B is a clock in which “hour / minute / second” is displayed by the hands.

The second hand 33 is attached to and driven by a predetermined gear of the train wheel 47 in the same manner as a normal timepiece.
However, in a normal timepiece, the second hand is larger in length than other hour and minute hands, but the second hand 33 of the present embodiment is set to a shorter length than the hour hand 31 as shown in FIG. ing.

  The scale 27 is displayed at intervals of 6 degrees on the circumference centered on the rotation axis of the pointer in the area inside the scale 21 of the hour hand 31. That is, the scale display control means 414A sets a circular second hand scale display area 28 for displaying the scale 27 corresponding to the second hand 33, and the scale 27 is displayed over the entire circumference (360 degrees) of the second hand scale display area 28. it's shown. Further, the scale 27 every 5 seconds is formed by a straight line connecting the scales 27 located at point symmetry with respect to the rotation axis of the pointer for easy identification. For example, the scales of 0 seconds and 30 seconds are connected by a straight line.

The center angle θ1 of the hour hand index area 23 is about 60 degrees, and three scales 21 are displayed. Further, the central angle θ2 of the minute hand index area 24 is about 48 degrees, and nine scales 22 are displayed. However, the scales 21 and 22 may use the same display as in the first embodiment.
In addition, in the scale 21, the scale 21 representing the current time is displayed with a number representing the time adjacent thereto. In FIG. 6, the numeral “10” is displayed adjacent to the scale 21 representing 10:00.
Further, “Year 2006” representing the year and “Day 11/12” representing the date are displayed as information 200 in the non-index area.

Also in this embodiment, the same operational effects as those of the first embodiment can be obtained.
Further, since the second hand 33 is provided, the hour, minute and second time can be indicated by the hour hand 31, the minute hand 32 and the second hand 33.
Further, since the length of the second hand 33 is set shorter than that of the hour hand 31, it is possible to prevent the second hand 33 from overlapping the information displayed on the display panel 20, and even if the second hand 33 is provided, the readability of the information 200 is improved. Can be improved. That is, when the second hand 33 is set to be longer than the minute hand 32 as in a general clock, the second hand 33 makes one round in one minute, so that information is displayed so as not to overlap the second hand 33. It becomes difficult. For this reason, the second hand 33 may overlap the displayed information. On the other hand, in the present embodiment, since the second hand 33 is set short, the second hand 33 does not overlap the display information, and the instruction of the second hand 33 and the information readability can be improved.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
In the combination timepiece 1C of the third embodiment, as shown in FIG. 7, the rotation axes of the hour hand 31 and the minute hand 32 are not on the same axis as in the previous embodiment, but are separated on the plane of the display panel 20. Is arranged.
That is, the hour hand 31 is arranged on the upper left side of the display panel 20 and the minute hand 32 is arranged on the lower right side.
The scale display control means 414A displays four scales 21 with the center angle θ1 of the hour hand index area 23 set to 90 degrees, and displays 16 scales 22 with the center angle θ2 of the minute hand index area 24 set to 90 degrees. ing.
The information display control means 414B displays information 200 in the upper right and lower left areas of the display panel 20. In the present embodiment, day-of-week information and world time information consisting of city names and times of other cities are displayed.
However, the information to be displayed may be a date as in the above embodiment, or other information.

In the present embodiment, there are almost no display areas on the upper and left sides of the hour hand 31 and on the right and lower sides of the minute hand 32. For this reason, when the hour hand 31 is disposed in the right half of the scale display area 25, that is, when the hour hand 31 is disposed at the scale position from 0 o'clock to 6 o'clock, the information display control means 414B has the scale. The information display area is set so as not to overlap the hour hand index area 23. For example, the information display control means 414B reduces the information display area by reducing the character size of the displayed information.
Similarly, when the minute hand 32 is arranged in the left half of the scale display area 26, that is, when the minute hand 32 is arranged at the scale position of 30 minutes to 60 minutes, the information display control means 414B has the scale 22. The information display area is set so as not to overlap the minute hand index area 24.

Also in this embodiment, the same operational effects as those of the first embodiment can be achieved.
In addition, the information display control means 414B displays information 200 in two areas on the upper right and lower left of the display panel 20. Information display control in these areas is performed by the hour hand 31 and the minute hand 32 that are arranged apart from each other. Since each of the hour hand 31 and the minute hand 32 can be determined independently of the scale display areas 25 and 26, display control can be easily performed. it can.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described.
As shown in FIG. 8, the combination timepiece 1D according to the fourth embodiment is provided with scales 21 and 22 for the hour hand 31 and the minute hand 32 continuously.
That is, in the present embodiment, the scale display control means 414A is configured such that the angle (intersection angle) θ3 formed by the hour hand 31 and the minute hand 32 detected by the drive control circuit unit 412 which is the pointer position detection means is a predetermined angle (for example, 90 degrees) or less, the hour hand index area 23 and the minute hand index area 24 are set in succession, and the scales 21 and 22 of the index areas 23 and 24 are positioned equidistant from the rotation axis of the pointer. To display.
In addition, when the angle formed by the hour hand 31 and the minute hand 32 is larger than a predetermined angle, the scale 21 displayed in the hour hand index area 23 is displayed in the minute hand index area 24 as in the first embodiment. It displays in the area | region inside the scale 22 displayed.

According to this embodiment, the same operational effects as those of the first embodiment can be obtained.
Furthermore, when the scales 21 and 22 are displayed continuously, the update frequency of the scales 21 and 22 is higher than when the scales 21 and 22 are displayed independently as in the first embodiment. The power consumption can be further reduced. For example, in FIG. 8, at around 9:50, the crossing angle θ3 of the hour hand 31 and the minute hand 32 becomes almost zero. At this time, the hour hand index region 23 for the hour hand 31 has a central angle θ1 of about 30 degrees and the radius length thereof is the same as that of the minute hand index region 24, and the minute hand index region 24 for the minute hand 32 has a central angle. If θ2 is about 120 degrees, the scales 21 and 22 can be made continuous over a range of about 120 degrees as shown in FIG.
In this case, until the minute hand 32 moves for about 20 minutes, that is, until it moves 120 degrees at the rotation angle, the instructions of the hands 31 and 32 can be read even if the scales 21 and 22 are continuously displayed. For this reason, since it is not necessary to update the display of the scales 21 and 22 for 20 minutes, the update frequency of the scale display can be reduced, and the power consumption can be further reduced. Further, since the scales 21 and 22 are continuously formed, as compared with the case where the scales 21 and 22 are displayed in a shifted manner in the radial direction of the scale display areas 25 and 26 as in the first embodiment. Therefore, it is possible to make a design that is close to a general clock scale display and is familiar to the user and easy to grasp.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described.
In the fifth embodiment, as shown in FIG. 9, the pointer-type display device of the present invention is used for a meter 100 of a measuring instrument. Specifically, a speedometer incorporated in an instrument panel of an automobile and It is used for a meter 100 for a thermometer.
The meter 100 is provided with a speed instruction needle 101 and a temperature instruction needle 102, and the entire surface is a display panel 103.
On the display panel 103, each index area (not shown) for each pointer is set according to the position of each pointer 101, 102, and scales 104, 105, 106 are displayed in the index area. Here, the scales 104 and 105 are displayed in black, but the scale 106 is displayed in gray. Further, on the display panel 103, speed information 201 and temperature information 202 are displayed by digital display in addition to instructions by the hands 101 and 102.

In this embodiment as well, the scales 104 and 105 are displayed corresponding to the pointers 101 and 102 as in the above embodiments, so that the readability of the pointers can be improved.
Furthermore, since the scales 104 and 105 are displayed only in the set index area, other areas on the display panel 103 can be used for various information, for example, digital display of measured values. In addition, since the display area of these information is set to other than the index area, the hands 101 and 102 do not overlap the display information, and the readability of the display information can be improved.

  Further, since the scale 105 is displayed in black while the scale 106 is displayed in gray, even if the pointer 102 moves greatly when the display panel 103 is configured by EPD, the pointer 102 moves. The scale 105 can be displayed following the above. That is, when the display panel 103 is composed of EPD, it takes some time to change the display from white to black. For this reason, if the pointer 102 suddenly moves out of the area of the scale 105, the display of the scale 105 in accordance with the position of the pointer 102 may not be in time. On the other hand, since the gray display can be changed to the black display in a shorter time than the case of changing from white to black, if the gray scale 106 is provided on both sides of the scale 105, the pointer 102 is moved. The scale 106 may be changed to the scale 105, and the scale 105 can be displayed quickly.

[Sixth Embodiment]
Next, a sixth embodiment of the present invention will be described.
As shown in FIG. 10, the timepiece 1E of the sixth embodiment is different from the above-described embodiment in that information is also displayed on the outer peripheral side of the index area, that is, the non-index area set in the extending direction of the hands 31 and 32. Is different.
In addition, although the table clock is illustrated in FIG. 10, it is applicable also to a wristwatch or a wall clock.

The timepiece 1 </ b> E includes a display panel 20 having a rectangular display area and a plurality of operation buttons 455 to 459 as the external input device 45.
As shown in FIG. 11, the control circuit 41 of the timepiece 1E is provided with a schedule information storage unit 417 for storing schedule information in addition to the configuration of the first embodiment, and the buttons 455 to 459 are used. Schedule information can be input. The schedule information includes at least schedule information indicating the content of the schedule and schedule time information indicating the time of the schedule.

  On the display panel 20, an hour hand index area 23 and a minute hand index area 24 are set by the scale display control means 414A, and arc-shaped scales 21 and 22 are displayed in the index areas 23 and 24, respectively.

In the display area of the display panel 20, portions other than the index areas 23 and 24 are non-index areas. Accordingly, the non-index area includes areas on the outer peripheral side of the index areas 23 and 24 as shown in FIG.
Various information is displayed in the non-index area by the information display control means 414B. Specifically, the calendar information of the date and day of the week and the scale information indicating the time displayed outside the scale 21 (in FIG. 10, the numbers “10, 11” representing 10:00 and 11:00 are displayed. Information related to the time is displayed.

  In the present embodiment, schedule information is displayed as information related to time. The schedule information includes schedule information indicating the contents of the schedule and schedule time information indicating the time of the schedule. As shown in FIG. 10, the schedule information 501 is text information indicating schedule contents, and is, for example, “meeting”. The schedule time information 502 is displayed along the outer periphery of the scale 21 and from a position indicating the schedule disclosure time (for example, a scale position at 10 o'clock) to a position indicating the end time (for example, a scale position at 11 o'clock). It is picture information of the shape. In the schedule time information, the schedule start time and the end time may be displayed as numbers.

  On the other hand, on the outer peripheral side of the scale 22 corresponding to the minute hand 32, that is, in the extending direction of the minute hand 32, schedule related information 503 is displayed as schedule information related to time. The schedule related information 503 is, for example, character information indicating that the current time exceeds 30 minutes with respect to the conference schedule time information from 10:00. The schedule related information 503 may also be displayed with a picture other than characters.

In this embodiment, the user first appropriately operates the buttons 455 to 459 to shift to the schedule registration mode. Then, a schedule registration screen is displayed in the non-index area of the display panel 20 by the information display control means 414B.
In this state, the user operates the buttons 455 to 459, inputs the schedule contents and time information (start time and end time), stores them in the schedule information storage unit 417, and ends the schedule registration mode.
Note that the clock 1E may be provided with a function of receiving data wirelessly or by wire, and schedule information registered in an external personal computer or a mobile phone may be transferred and stored in the schedule information storage unit 417.

When the hour hand 31 and the minute hand 32 of the timepiece 1E are moved by hand movement, the display of the scale 21 is moved as the hour hand 31 is moved, and the display of the scale 22 is moved as the minute hand 32 is moved.
At that time, when the schedule information is registered in the schedule information storage unit 417 and the time range displayed on the scale 21 includes the time of the schedule time information 502, the information display control unit 414B The band-like schedule time information 502 is displayed along the outer periphery of the scale 21 and the schedule information 501 is displayed.
Further, the schedule related information 503 is displayed outside the scale 22.
Further, for example, when the current time is in the schedule time, the information display control unit 414B may display “ALARM in progress” on the display panel 20 as the auxiliary information 504.

According to the present embodiment, the same operational effects as those of the above-described embodiments can be obtained, and the following operational effects can be further achieved.
That is, the timepiece 1E of the present embodiment also displays various types of information on the outer peripheral sides of the scales 21 and 22, that is, the non-index areas in the extending direction of the hands 31 and 32. For this reason, in particular, the schedule information related to the time can be displayed outside the scale 21 corresponding to the schedule time, so that the user can surely and easily grasp the schedule information related to the current time.
Furthermore, since the schedule time information 502 is displayed in a band shape, the user can easily grasp the schedule time visually.
In addition, the information display control means 414B of the present embodiment also displays the schedule related information 503 on the display panel 20, so that the current status can be notified to the user in more detail. Furthermore, since the information display control means 414B of this embodiment also displays the auxiliary information 504 on the display panel 20, it can notify the user of the current situation in more detail.

In addition, since the display panel 20 is formed in a rectangular shape, in particular, at the four corner portions, the scale display regions 25 and 26 that are set in a circle around the rotation axes of the hands 31 and 32, that is, spaces that do not become index regions. Occurs.
In the present embodiment, since various types of information are also displayed in the non-index areas provided outside the scale display areas 25 and 26, the display area of the display panel 20 can be used effectively, It can be displayed effectively.

[Seventh Embodiment]
Next, a seventh embodiment of the present invention will be described. This embodiment is different from the first embodiment in that the scales 21 and 22 are partially displayed, and other configurations are the same.
That is, as shown in FIG. 12, in this embodiment, the scale display control means 414 </ b> A corresponds to the positions of the scales 21, 22 corresponding to the positions indicated by the current hands 31, 32 on the scales 21, 22 displayed on the display panel 20. Some of the scales 21A and 22A of 22 are displayed thickly. Specifically, the thickness of the arc-shaped connection line of each scale 21A, 22A is changed.
In addition, in the scales 21 and 22, the scales 21A and 22A that are displayed thickly may display a predetermined range thickly around the time indicated by the hands 31 and 32, for example. In this case, for example, in the scale 22 of the minute hand 32, the scale display control means 414A moves the scale 22A displayed thickly on the scale 22 by the scale of 1 minute when the minute hand 32 moves by 1 minute.
Further, the scale display control means 414A may update the scales 21A and 22A that are displayed thick at regular intervals in conjunction with the movement of the hands 31 and 32. For example, as illustrated in FIG. 12, the scale display control unit 414A displays the area of 8 to 12 minutes of the scale 22 thickly while the minute hand 32 indicates 8 to 12 minutes, and the minute hand 32 has 12 While the minutes to 17 minutes are instructed, the area of 12 to 17 minutes on the scale 22 may be displayed thickly, and the area to be displayed on the scale 22 thickly at intervals of 5 minutes may be moved by 5 minutes. .

If a part of the scales 21 and 22 is displayed thickly as in the present embodiment, the user can easily grasp the positions of the hands 31 and 32, and even if the hands 31 and 32 cannot be confirmed, the outline Can be recognized.
Instead of thickening part of the scales 21 and 22, part of the scales 21 and 22 may be changed, or both the color and thickness may be changed. In short, it is only necessary that a part of the scales 21 and 22 can be distinguished from the other parts of the scales 21 and 22.

[Eighth Embodiment]
Next, an eighth embodiment of the present invention will be described. In the seventh embodiment, the thicknesses of the scales 21 and 22 are changed in conjunction with the hands 31 and 32. However, in this embodiment, as shown in FIG. The change is made to give meaning to the transition of the time indicated by the hands 31 and 32.

The scale display control means 414A of the present embodiment updates the scale 22 for the minute hand 32 at intervals of 15 minutes. That is, the scale display control means 414A uses the scale 22 for 0 to 15 minutes when the minute hand 32 indicates 0 to 15 minutes, 15 to 30 minutes, 30 to 45 minutes, 45 to 60 minutes, 15 -30 minutes, 30-45 minutes, 45-60 minutes are switched and displayed.
Then, the scale display control means 414A displays the scale 22B portion for the next 5 minutes (5 to 10 minutes in FIG. 13) thicker on the scale 22 than the first 5 minutes, and further for the next 5 minutes. The scale 22C portion (10 to 15 minutes in FIG. 13) is displayed thicker.

  According to this embodiment, the user can easily determine which area the current time zone is by grasping the thickness of the scale 22 indicated by the minute hand 32, and the elapsed time and the remaining time in a meeting or the like. You can also check progress such as time.

  Instead of making the connecting lines of the scales 21 and 22 thick, a part of the colors of the scales 21 and 22 may be changed, or both the color and the thickness may be changed. In short, it is only necessary that a part of the scales 21 and 22 can be distinguished from the other parts of the scales 21 and 22.

[Ninth Embodiment]
Next, a ninth embodiment of the present invention will be described. This embodiment is different from the first embodiment in that the scales 21 and 22 are partially displayed, and other configurations are the same.
That is, as shown in FIG. 14, in the present embodiment, the scale display control means 414 </ b> A corresponds to the scales 21, 22 corresponding to the positions indicated by the current hands 31, 32 on the scales 21, 22 displayed on the display panel 20. The color of some of the scales 21A and 22A of 22 is darker than the other parts of the scales 21 and 22.
In the scales 21 and 22, the portions of the scales 21A and 22A that display dark colors may be displayed in a predetermined range with a focus on the time indicated by the hands 31 and 32, for example. In this case, for example, in the scale 22 of the minute hand 32, the scale display control means 414 </ b> A moves the portion of the scale 22 whose color is darkly displayed by one minute when the minute hand 32 moves for one minute.
Further, the scale display control means 414A may update the scales 21A and 22A that are displayed thick at regular intervals in conjunction with the movement of the hands 31 and 32. For example, as illustrated in FIG. 14, the scale display control unit 414 </ b> A displays the area of 8 to 12 minutes of the scale 22 in a dark manner while the minute hand 32 indicates 8 to 12 minutes, and the minute hand 32 has 12 While the minute to 17 minutes are instructed, the area of 12 to 17 minutes of the scale 22 is displayed darkly, and the area of the scale 22 that is thickly displayed at intervals of 5 minutes may be moved and updated by 5 minutes. .

If a part of the scales 21 and 22 is darkly displayed as in the present embodiment, the user can easily grasp the positions of the hands 31 and 32, and even if the hands 31 and 32 cannot be confirmed, the outline Can be recognized.
It should be noted that the color is not limited to a part of the scales 21 and 22, and the hue, saturation, and luminance may be changed as appropriate to change the colors.

[Tenth embodiment]
Next, a tenth embodiment of the present invention will be described. In the present embodiment, as shown in FIG. 15, the colors of the index areas 23 and 24 are displayed differently from the colors of the non-index areas. Also, the colors of the index areas 23 and 24 are made different from each other. Furthermore, in the minute hand index area 24, a sector-shaped pointer instruction area 24A is set. The pointer instruction area 24A is displayed in a color different from the colors of the index areas 23 and 24 and the non-index area. The pointer instruction area 24 </ b> A is displayed according to the position of the minute hand 32, and its central angle is smaller than that of the minute hand index area 24.

  In the present embodiment, a second hand 33 is provided. Similarly to a general timepiece, the second hand 33 has a length dimension from the rotation axis of the second hand 33 to the tip thereof equal to or greater than a length dimension from the rotation axis of the minute hand 32 to the tip of the minute hand. In addition, the scale corresponding to the second hand 33 is not displayed on the display panel 20.

According to this embodiment, since the colors of the index areas 23 and 24 are different from the colors of the non-index areas, the index areas 23 and 24 can be easily grasped, and the current positions of the hands 31 and 32 can be determined. Easy to grasp.
Further, since the colors of the index regions 23 and 24 are also different from each other, the positions of the hour hand 31 and the minute hand 32 can be easily grasped, and the approximate time can be grasped more easily.
Furthermore, since the pointer indicating area 24A having a smaller width (center angle) than the minute hand index area 24 is displayed according to the position of the minute hand 32, the position of the minute hand 32 is confirmed by checking the pointer indicating area 24A. Can be grasped more easily.

  Furthermore, the colors of the index areas 23 and 24 and the pointer instruction area 24A can be set so that the pointers 31 and 32 are conspicuous, and the visibility of the pointers 31 and 32 can be improved.

In the present embodiment, the second hand 33 is provided, but since the scale for the second hand is not displayed, the information displayed in the non-index area does not overlap the scale for the second hand, and the information is easy to read. Can be prevented from decreasing.
Further, as shown in FIG. 15, the second hand 33 may overlap the information 200 displayed in the non-index area, but the second hand 33 has a higher moving speed than the minute hand 32 and is usually formed thin. Therefore, even if it overlaps with the information 200, it moves from the information 200 portion in a few seconds, so there is no possibility that the readability of the information 200 displayed in the non-index area is lowered.

[Modification of Embodiment]
It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, the scale display control means 414A may move the index area by a predetermined scale in the movement direction of the pointer whenever the pointer moves by a predetermined scale on the scale for each pointer. The predetermined scale may be one scale or two or more scales.
For example, in the case of the scale 22 for the minute hand 32, when the minute hand 32 moves for 1 minute (6 degrees in rotation angle), the index area 24, that is, the scale 22 is moved by one scale (6 degrees in rotation angle) to thereby move 1 scale. The scale 22 may be moved every minute.
In this case, there is an advantage that the pointer can always be arranged at the center position of the index area. On the other hand, in the case of the minute hand 32, the scale display must be updated every minute, the update frequency is increased, and the power consumption increases when a memory-type display element such as EPD is used for the display panel 20. Therefore, the embodiment is preferable in that power consumption can be reduced.
On the other hand, in the case of moving by two or more graduations, for example, in the case of the graduation 22 for the minute hand 32, it may be set between 4 graduations and 30 graduations. If the amount of movement of the scale 22 is less than 4 scales, the scale display is updated more frequently and power consumption is increased. If it is 30 scales or more, the scale 22 must be displayed for 30 scales and is not indexed. This is because the area becomes smaller.

  Further, the scale display control means 414A may move the index area of the pointer by a predetermined distance in the movement direction of the pointer at regular time intervals. In the case of a meter of a measuring instrument, the moving speed of the pointer is indefinite, but in the case of a watch, the moving speed of each pointer is constant. Therefore, if the index areas corresponding to the timepiece hand 31, the minute hand 32, and the second hand 33 are moved at regular time intervals, the index area, that is, the scale can be displayed in conjunction with the position of the hands. For example, in the case of the scale 22 for the minute hand 32, the scale 22 can be displayed in conjunction with the movement of the minute hand 32 if the index region 24 is rotated 30 degrees every 5 minutes.

Furthermore, the display update interval of each scale is preferably set to the same interval as the display deterioration compensation operation interval of the display panel 20, and the movement amount of each scale is preferably set according to the display update interval. An operation interval for display deterioration compensation in the display panel 20 having a memory property is, for example, an interval of 5, 10, 15, or 30 minutes. Even during the display deterioration compensation operation, the power is consumed although it is a power of several tenths to a fraction of that in the case of changing the normal display. For this reason, if the display deterioration compensation operation and the scale display update operation are performed at different timings, the power consumption increases accordingly.
On the other hand, if the display deterioration compensation operation and the scale display update operation are performed at the same timing, power consumption can be reduced.

The scale display control means 414A may switch the scale display update interval and the display degradation compensation operation interval based on the time (internal time) of the time measuring means.
For example, the user of the watch 1 usually checks the time relatively frequently during the daytime, but removes the watch 1 at night, and therefore rarely checks the time with the watch 1. Therefore, at night, since the display quality of the display panel 20 is degraded, there are few problems, and the operation interval for display deterioration compensation can be increased.
Therefore, the scale display control means 414A sets the display deterioration compensation operation interval to 30 minutes in the night time zone (for example, from 11:00 pm to 7:00 am), and the scale 22 of the minute hand 32 has a center angle of 180 degrees. A scale of 30 minutes is displayed, and in other time zones (for example, from 7:00 am to 11:00 pm), the display deterioration compensation operation interval is set to 15 minutes, and the scale 22 of the minute hand 32 also has a central angle of 90. Control such as displaying a scale of 15 degrees, that is, a scale of 15 minutes may be performed.
If such control is performed, there is no problem even if the contrast of the scale display is slightly lowered at night. Therefore, the display deterioration compensation operation interval can be made longer than in the daytime, and the power consumption can be reduced.

Note that the scale display update interval and the display deterioration compensation operation interval are not limited to those that are changed based on the internal time of the timepiece 1, but may be changed based on the use state of the user. For example, in the case of a wristwatch, the state of being worn on the user's arm may be detected. If the wristwatch is worn, the interval may be shortened, and if not worn, the interval may be lengthened.
At this time, as a method of detecting the wearing state of the watch, for example, an acceleration sensor is provided inside the watch to detect the movement of the watch, or when a thermoelectric generator or a rotating weight generator is built-in, It is only necessary to detect the power generation state and determine the wearing state of the watch.

  Further, when the scale display is updated, the color of the scale may be changed. For example, when the scale 22 of the minute hand 32 is updated at intervals of 15 minutes, the scale 22 is displayed in black when the scale 22 is 0 to 15 minutes, and is displayed in blue when the scale 22 is switched to the scale 30 to 30 minutes. It may be displayed in yellow when the scale 22 is switched to ˜45 minutes, and may be displayed in red when it is switched to 45 to 60 minutes. In this case, the time zone indicated by the current minute hand 32 can be grasped by the color of the scale 22, and the progress of the outline can be easily confirmed in a meeting or the like.

The setting angle of the central angle θ1 of the hour hand index area 23 and the central angle θ2 of the minute hand index area 24 is not limited to that of the first to fourth embodiments, and may be set as appropriate in the implementation.
For example, when only one pointer is provided, the center angle of the index area may be increased to 270 degrees. This is because even if such a setting is made, information can be displayed using the remaining area, and the legibility of the information can be ensured.
On the other hand, if there are two pointers and the central angle of each index area is 180 degrees or more, the crossing angle of each pointer is 180 degrees, that is, the whole area of the scale display area is indexed when positioned on the opposite side across the rotation axis. It becomes an area, and it becomes difficult to secure an area for displaying other information. For this reason, when there are two pointers, it is preferable that the center angle of each index area is set to about 120 degrees or less, preferably 90 degrees or less, from the viewpoint of ensuring a sufficient non-index area. When there are three hands, it is preferable to set the center angle of each index area to 90 degrees or less. Further, when the number of pointers is three, even if the central angle of the index area is reduced to 90 degrees or less, if the pointers are arranged at intervals of 120 degrees, for example, the non-index areas are assigned to the index areas. It is distributed in small spaces between areas, and information must be displayed using each non-index area. Therefore, as in the second embodiment, it is more preferable to shorten the length of the third or more hands so as not to hinder information display.
Furthermore, the center angle of the index area of the pointer may be set to 30 degrees or less. However, if the value is too small, the number of scales that can be displayed is reduced, and the legibility of the pointer may be lowered. The index area may be set in consideration of the legibility of the scale interval and the pointer.

In the embodiment, the scale is displayed on the outer periphery (arc) portion of each index area. However, the scale may be displayed on another part in the fan-shaped index area. For example, the scale may be displayed so as to overlap the intermediate portion in the radial direction of the index region (the intermediate portion between the center of the circle and the arc), that is, the intermediate portion between the rotation axis and the tip of the pointer.
Further, since the index area is for a rotating pointer, the index area is set in a sector shape. However, the shape, size, and the like of the index area may be set in accordance with the movement form of the pointer. For example, when the pointer is slid linearly, the index region may be formed in a band shape.
Furthermore, the index area may be provided only in the area corresponding to the distal end portion of the pointer, and the area corresponding to the proximal end portion of the pointer may be a non-index area. For example, the index area for the rotating pointer is not limited to a fan-shaped index area, and a curved belt-shaped area, that is, an arc-shaped index area may be used. In short, the index region may be a region having an area for displaying at least a scale for reading the indication value of the pointer.

  In the display panel 20, the scales 21, 22, 27, 104, and 105 may display numbers adjacent to the scales. For example, the scale 21 in FIG. 6 also displays a number representing a time such as “10”. If numbers are also displayed in this way, there is an advantage that the amount indicated by the pointer can be grasped more easily.

The information displayed in the non-index area of the display panel 20 is not limited to that of each of the embodiments described above, and displays various information such as date, world time, chronograph, schedule information, Todo (work list) information, and address information. May be.
Further, when the second hand is not provided as in the first embodiment, second information may be displayed on the display panel 20.
Furthermore, the pointer-type display device may be configured to be provided with a communication function such as wireless so that information received via a communication function such as mail or news can be displayed on the display panel 20.
Further, the information display by the information display control means 414B is not necessarily required, and only the scale display control means 414A may be provided in the display panel drive circuit 414 so that only the scale is displayed on the display panel 20.
Furthermore, the user may be able to select a mode for displaying information and a mode for displaying only a scale without displaying information. In the mode of displaying only the scale, a circular scale may be provided in the same manner as a normal timepiece so that the instructions of the pointer 31, the minute hand 32, and the second hand 33 can be accurately read. .

  Further, in the second embodiment, the scale 27 is displayed on the entire circumference of the second hand scale display area 28. However, like the hour hand 31 and the minute hand 32, a sector-shaped second hand index is provided in the second hand scale display area 28. An area may be set and the scale 27 may be displayed only in the index area.

The display panel 20 is not limited to a display element having a memory property such as EPD, and a display element such as a liquid crystal display or an organic EL display may be used.
In particular, when rewriting display is necessary frequently, such as various measuring instruments and second hand scales, it is preferable to use a liquid crystal display or the like that has a fast response speed for rewriting display.
Even when EPD is used for the display panel 20, a certain voltage is applied in advance to the scale that is arranged adjacent to the currently displayed scale, that is, the scale that may be displayed next. If the display is applied and the display is set to an intermediate gradation, the scale can be quickly displayed in conjunction with the movement of the pointer. For example, when an EPD capable of displaying multiple gradations from white to black is used and the scale is displayed in black, if the scale to be displayed next is controlled to an intermediate gradation, that is, gray display, the voltage can be further increased. When applied, the display can be immediately changed to black display, and the scale can be quickly displayed following the movement of a pointer having a fast moving speed such as a second hand.

Furthermore, the information displayed in the index area and the non-index area may be displayed in association with each other.
For example, in a timepiece, when various generators such as solar are incorporated, information relating to the power generation is indicated by the second hand 33 or the like. When this power generation information is indicated by the second hand 33, the indication content may be displayed by the color and thickness of the indicated position scale or the color of the index area. That is, if the scale at the indicated position when the power generation amount is large is displayed in green and the scale at the designated position when the power generation amount is small is displayed in red, the user can easily grasp the power generation state. Further, the description of the color of the scale may be displayed with characters or the like in the non-index area. In that case, if information is displayed in the same color as the color of the scale or index area, the user can easily grasp the relevance thereof.
Not only information related to power generation, but status information inside the watch such as temperature and magnetic field detection, operation information of the crown 451 and buttons 452, 453, information transmitted from the outside wirelessly and stored inside the watch, etc. Even when various types of information are displayed, it is only necessary to control the color of the scale or the color of the information in the non-index area so that the user can easily grasp the information.

The present invention is not limited to the case of being applied to the timepiece and the speed / thermometer as in the above-described embodiments, but can be widely applied to indicators of various measuring instruments. In particular, since the scale display can be freely updated, the measurement values of a plurality of measuring instruments can be switched and displayed.
The present invention may be applied to a timepiece having a small second hand attached to a rotation shaft at a position different from the rotation shaft of the hour hand and the minute hand. In this case, the scale display control means sets a small second hand index area corresponding to the small second hand, and controls display and non-display of the scale in the small second hand index area in conjunction with information display or the like. .
