Description

The present invention relates to a display device that causes changes such as appearance and disappearance of designs and symbols by a mechanical and simple mechanism without using an electric display mechanism such as a liquid crystal display, and uses the same. Regarding the clock.

There are two types of display devices used in watches and the like: analog type and digital type. The analog display device consists of a dial on which letters and symbols for indicating time are written, an hour hand and a minute hand indicating the present hour and minute, and a drive device (movement) for driving them. By pointing to letters and symbols on the hour and minute hands, which change their positions every moment, the time can be read from the physical positional relationship and the time can be recognized.
On the other hand, the digital display device displays numbers representing hours and minutes on an electric display device such as a liquid crystal display device. The time can be read and recognized directly from the number.
Both the analog method and the digital method represent the current time, and it is possible to calculate and know the length of time that has passed from the current time read and how long it will take to reach a certain time in the future.

As described above, the basic function of the display device used in the clock is to know the current time, but there is an increasing demand for the display device to express further.
For example, there is a demand for a watch that can feel the flow of time itself. As an example of this, an hourglass cannot accurately represent the time, but the behavior of falling and stacking sand grains is fun to watch. The behavior of the sand grains makes us feel the invisible flow of time.

As a clock that can feel the passage of time, for example, a design in which numbers on the dial appear and disappear is proposed in Design Document 1.
This watch has a disk-shaped hour hand and a hand-shaped minute hand on the dial that represents 1 to 12 o'clock, and the hour hand is a part of the opaque disk where the numbers on the dial can be seen exactly. A small circular transparent portion and a slit-shaped transparent portion are provided.
At the exact time (hour) at each time, the numbers overlap with the transparent circle and the numbers on the dial can be read, but at times other than the hour, the numbers do not overlap with the transparent circle, and the numbers are before and after the transparent slit. I don't know what time it is because the numbers are only slightly visible. To make up for this shortcoming, a needle-shaped minute hand is provided, but it is not sufficient.

Design Registration No. 1421738 Gazette

It can be said that the above-mentioned conventional technique expresses the flow of time in that it visualizes the changes in which the numbers appear and disappear on the dial, but the numbers appear and can be recognized properly only at the moment of the hour. However, if the time deviates from that, there is a problem that it is not possible to know what time the hour hand indicates. In addition, since a needle-shaped minute hand is provided to compensate for this, the attractiveness of the design that expresses the time without relying on the hands is greatly impaired.
As a result, the effect of feeling the passage of time is impaired.

The present invention solves the above-mentioned problems, and provides a display device that can visualize the figures and symbols while being a mechanical analog display device and can feel the flow of time that a digital display device does not have, and a clock using the display device.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 8.
[First Embodiment]

The display device according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6. With reference to FIG. 1, the display device 1 according to the present embodiment visualizes (displays) a figure or a symbol by utilizing the shielding complement effect, and is a base member 2 and a base surface 2a of the base member 2. It is provided with a mask member 3 arranged close to and facing each other, and a drive mechanism (not shown) for moving the mask member 3 relative to the base surface 2a in the first predetermined direction D1.

As the material of the base member 2, various known solids and elastic bodies can be appropriately used. For example, as materials that can be easily manufactured, wood, plastic, rubber, metal, ceramics, etc., combinations thereof, and various materials thereof are used. Can be used with the surface treatment of.

The mask member 3 is made of a plate-shaped member made of a transparent material capable of holding a constant shape, and the base surface 2a can be visually recognized via the mask member 3. Further, the mask member 3 is provided with a mask pattern 5 for partially shielding the base surface 2a so that the portion of the base surface 2a that overlaps with the mask pattern 5 cannot be visually recognized.

The mask pattern 5 is formed by using a material that blocks light from the base surface 2a, and may be formed by being printed on the mask member 3 using, for example, an opaque pigment ink, or an optical filter on the mask member 3. Or, a plurality of polarizing filters and the like may be arranged and formed.

The mask pattern 5 includes a first stripe pattern 50 and a second stripe pattern 51 different from the first stripe pattern 50, and the second stripe pattern 51 is on the upstream side of the first predetermined direction D1 with respect to the first stripe pattern 50. Is located in. The mask pattern 5 also includes another stripe pattern (not shown) located on the downstream side of the first predetermined direction D with respect to the first stripe pattern 50, but here, in order to facilitate understanding of the invention, the stripe pattern 5 is included. The explanation of the pattern is omitted. The first striped pattern 50 and the second striped pattern 51 are composed of a plurality of first lines 50a and second lines 51a arranged substantially in parallel in a second predetermined direction D2 perpendicular to the first predetermined direction D1, respectively.

The base member 2 has a first diagram element 6a and a second diagram element 6b. In the example shown in FIG. 1, the first diagram element 6a and the second diagram element 6b are shown on the base surface 2a. The second diagram element 6b is located on the downstream side of the first predetermined direction D1 with respect to the first diagram element 6a. As shown in FIG. 2A, the first diagram element 6a is a specific portion corresponding to the first stripe pattern 50 from the first figure or symbol (here, the number “1”) as the original figure 4a. It is a set of partial images left after erasing. Further, as shown in FIG. 2B, the second diagram element 6b is the first stripe pattern 50 from the second graphic or symbol (the number “2” in the example shown in FIG. 2) as the original FIG. 4b. It is a set of partial images remaining after erasing a specific part corresponding to.

In such a configuration, as shown in FIG. 3, when the mask member 3 is located at a predetermined first position P1, the first diagram element 6a is visually recognized from the gap of the first stripe pattern 50 through the transparent portion of the mask member 3. It is exposed as much as possible, the original figure 4a is visualized by the shielding complement effect, and the viewer can read the original figure 4a (“1”). In this state, the second diagram element 6b is at least partially shielded by the other striped pattern (not shown) described above, and the visualization of the original FIG. 2b is prevented.

When the mask member 3 moves from this state to the predetermined second position P1 in the first predetermined direction D1, the second diagram element 6b is visually exposed from the gap of the first stripe pattern 50 through the transparent portion of the mask member 3. However, the original figure 4b is visualized by the shielding complement effect, and the viewer can read the original figure 4b (“2”). On the other hand, the first diagram element 6a is partially shielded by the second stripe pattern 51, and the shielding complementing effect is impaired due to the decrease in the exposure rate, which hinders the visualization of the original diagram 4a. Here, in the following description, "display" means that the original figure is visualized by the shielding complement effect, and "hidden" or "not displayed" means that the shielding complement effect is impaired or hindered. It shall mean that the figure is not visualized.

The exposure rate refers to the ratio of the figure appearing from the gap of the mask pattern 5. As shown in FIG. 3, when the mask member 3 is located at the first position P1, the exposure rate of the first graphic element 6a becomes the maximum (100%). Further, as shown in FIG. 4, when the mask member 3 is located at the second position P2, the exposure rate of the second diagram element 6b becomes the maximum (100%), while the first diagram element 6a has the second stripe. Partially shielded by the pattern 51, the exposure rate of the first diagram element 6a is much less than 50%, and the original diagram 4a is hidden.

As described above, in the display device 1 of the present embodiment, the original figure 4a is displayed by locating the mask member 3 at the first position P1, and the original figure 4b is displayed by locating the mask member 3 at the second position P2. While it is displayed, the original FIG. 4a is hidden.
Here, in order to obtain the preferable shielding complementing effect as described above, in the third predetermined direction D3 (direction perpendicular to the base surface 2a) perpendicular to the first and second predetermined directions D1 and D2, the elements 6a, It is preferable that 6b and the mask member 3 are sufficiently close to each other. Specifically, the distance between the elements 6a and 6b and the mask member 3 is 0.1 times or less the predetermined height H1 shown in FIG. It is preferably present, and more preferably 0.01 times or less.

Then, it is conceivable to momentarily switch from the state in which the original drawing 4a is displayed as shown in FIG. 3 to the state in which the original drawing 4b is displayed and the original drawing 4a is not displayed as shown in FIG. In the present embodiment, the display state shown in FIG. 3 is gradually changed to the display state shown in FIG. 4 as follows, so that the passage of time can be felt.

FIG. 5 shows a state in which the mask member 3 has slightly moved from the first position P1 to the first predetermined direction D1 but has not reached the second position P2.
The ratio of the first diagram element 6a shielded by the first stripe pattern 50 is slightly higher than that at the first position P1, and the shielding complementing effect is slightly impaired, but there is a problem in reading the original diagram 4a. However, the visualization of the original figure 4a is established. In such a state, when the ratio of the first figure element 6a shielded by the first stripe pattern 50 is small, that is, the exposure rate of the first figure element 6a from the gap of the first stripe pattern 50 (mask pattern 5). Is realized when is sufficiently large, and specifically, if the exposure rate is 50% or more, the visualization is sufficiently established.
Then, in order to gradually change the display state, the exposure rate of the figure element (shielding rate of the figure element) may be gradually changed.

FIG. 6 is a conceptual diagram showing the state of change in the display state by the change in the exposure rate of the first diagram element 6a. The vertical axis represents the ratio (exposure rate) at which the first diagram element 6a is exposed from the gap of the mask pattern 5, and the horizontal axis represents the position of the mask member 3 in the first predetermined direction D1. The time length (predetermined time length) required for moving to P2 is L.

As shown in FIG. 6, since the exposure rate of the first diagram element 6a is 100% at the first position P1, the original FIG. 4a is clearly displayed (state of FIG. 3). After that, as the mask member 3 moves from the first position P1 to the first predetermined direction D1, the exposure rate of the first diagram element 6a gradually decreases and reaches the second position P2 through an intermediate state as shown in FIG. Before reaching the second position P2, the exposure rate becomes 50% or less, and the original FIG. 4a is not displayed (state of FIG. 4).

Then, the time length (first time length) L1 at which the exposure rate of the first diagram element 6a becomes 50% or more is predetermined until the mask member 3 moves from the first position P1 to the second position P2. It is preferably 50% or more of the time length L, and by making the first time length L1 sufficiently longer than the predetermined time length L in this way, the state in which the original FIG. 4a is displayed is maintained sufficiently long. By gradually reducing the exposure rate, the degree of display in the original FIG. 4a can be gradually reduced.

Further, in the present embodiment, the exposure rate of the first diagram element 6a is set to gradually increase as the mask member 3 approaches the first position P1, and is on the upstream side of the first predetermined direction D1 from the first position P1. The time length (second time length) L2 required for the mask member 3 to move from the third position P3 to the first position P1 when the exposure rate of the first diagram element 6a reaches 50% at the third position P3 is , The first hour length is set to be shorter than L1. This means that the change is steeper when the original figure 4a appears (visualized and displayed), and the change is slower when it disappears.

Next, the conditions necessary for realizing the desired display / non-display of the original drawing (exhibition and suppression of the shielding complement effect) as described above will be described.

The desired display of the original drawing (demonstrating the shielding complement effect) is easy to realize when the number condition, the gap condition, and the angle condition described below are satisfied.
That is, as shown in FIG. 2A, the first diagram element 6a occupies a region having a predetermined height H1 in the second predetermined direction D2 on the base surface 2a, but the mask member 3 is located at the first position P1. At one time, the number of the first lines 50a overlapping the region on the base surface 2a occupied by the first diagram element 6a is 4 to 10, and a pair of adjacent first lines are adjacent to each other in the second predetermined direction D2. The size of the gap between the 50a and 50a is preferably 0.2 to 0.7 times the average value of the thicknesses of the pair of first lines 50a and 50a, and the number of the first lines 50a is 6. The number of lines is 8 to 8, and the size of the gap between the first lines 50a and 50a is 0.3 to 0.5 times the average value of the thicknesses of the pair of first lines 50a and 50a. Is more preferable.

If the number of the first line 50a is too small and too thin, or if it is too large and too thin, it becomes difficult to suppress the covering complement effect, and if the number of the first line 50a is too small and too thick, It becomes difficult to obtain a good shielding complementing effect, and if the number of the first lines 50a is too large and too thick, the region ratio of the first diagram element 6a to the first stripe pattern 50 becomes too small, and the original figure 4a is read. This is because it becomes difficult.

Further, the angle of each first line 50a with respect to the first predetermined direction D1 is preferably within ± 10 degrees, more preferably within ± 5 degrees. The larger the angle, the larger the change in the shielding rate with the movement of the mask member 3. Therefore, when the angle is larger than ± 10 degrees, the above-mentioned first time length L1 and second time length L2 become too short, and the original This is because the state in which the figure is displayed cannot be maintained for a sufficiently long time.

Next, it is easy to realize the desired non-display of the original drawing (suppression of the shielding complement effect) when the number condition and the gap condition described below are satisfied together.
That is, when the mask member 3 is at the second position P2, the first figure element 6a occupies in order to satisfactorily shield the first figure element 6a by the second stripe pattern 51 (the original figure 4a is hidden). The number of the second lines 51a overlapping the above region on the base surface 2a is 2 to 6, and the size of the gap between the pair of adjacent second lines 51a and 51a in the second predetermined direction D2. Is preferably 0.5 to 5 times the average value of the thicknesses of the pair of second lines 51a and 51a, and the number of the second lines 50a is 3 to 5 and the second line. It is more preferable that the size of the gap between the 51a and 51a is 1 to 3 times the average value of the thicknesses of the pair of second lines 51a and 51a.

If the number of the second line 51a is too small and too thin, it becomes difficult to suppress the covering complement effect, and if the number of the second lines 51a is too large and too thick, the covering complement effect is suppressed too much. It is not preferable because it becomes difficult to adjust the exposure of the first diagram element 6a from the gap of the second line 51a.

As described above, the display device 1 of the present embodiment gradually appears and gradually disappears so that a plurality of figures and symbols can be read by the shielding complement effect of the first stripe pattern 50, so that the figures and symbols can be recognized. It can be read not only for a moment but also for a certain period of time even if it deviates from it.

Therefore, an intermediate state from 100% display to 0% display can be appropriately represented, which has the effect of generating a "state progress" in which figures and symbols are gradually weathered.

Further, since the display device 1 of the present embodiment adjusts the shielding ratio and the changing speed by simultaneously adjusting the number of the first line 50a and the size of the gap and the angle with respect to the figure or the symbol to be displayed, the shielding is performed. It is possible to enhance the complement effect and make it easier to read the figures and symbols that you want to display.

Further, the display device 1 of the present embodiment adjusts the shielding ratio by simultaneously adjusting the number of lines 51a of the second line 51a and the size of the gap for the figures and symbols that are not desired to be displayed, so that the shielding complementing effect can be obtained. It is possible to make it difficult to read figures and symbols that you do not want to suppress and display.

Then, in the display device 1 of the present embodiment, since the change in the shielding ratio is asymmetric with respect to the moving direction, it is easy to understand that the display of a certain figure or symbol is about to end, and the display on the next figure or symbol is displayed. The transition can be made clearly.
[Second Embodiment]

Next, the display device according to the second embodiment of the present invention will be described with reference to FIGS. 7 and 8. In this embodiment, the same reference numbers are given to the members substantially the same as those in the first embodiment described above, and the description thereof will be omitted.

With reference to FIG. 7, the display device 101 according to the present embodiment is an application of the display device 1 to a clock, and has the same configuration as the display device 1, but the mask member 103 is a base member 102. It is different in that it is rotatable about a rotation drive shaft 7 extending from the center of the base surface 102a, and the first predetermined direction D1 is a rotation direction (clockwise direction) about the rotation drive shaft 7.

Therefore, the arrangement direction of the plurality of first lines 50a and the second line 51a constituting the first stripe pattern 50 and the second stripe pattern 51 of the mask pattern 105 is the radial direction of the mask member 103.

Further, on the base surface 102a, 12 figure elements corresponding to the hour character positions from 1 o'clock to 12 o'clock on the clock face (1 o'clock, 2 o'clock, and 3 o'clock in FIG. 7, respectively, correspond to each other). Only the first diagram element 106a, the second diagram element 106b, and the third diagram element 106c are shown).

Since the principle of displaying and hiding the original drawing using the shielding complement effect in the present embodiment is the same as that of the first embodiment described above, the description thereof will be omitted.

FIG. 8 is a conceptual diagram showing the state of change in the display state in the present embodiment by the change in the exposure rate of the figure. The vertical axis represents the ratio of the figure element exposed from the gap of the mask pattern 105, and the horizontal axis represents the moving position (rotation angle position) of the mask member 103 in the first predetermined direction D101. In the present embodiment, the mask member 103 is located at the first position P1 at 1 o'clock, is located at the second position P2 at 2 o'clock, and the predetermined time length L from the first position P1 to the second position P2 is 1 hour. ..

As shown in FIG. 8, when the mask member 103 is located at the first position P1, the first diagram element 106a is greatly exposed, the character "1" in the original figure is visualized (displayed) to the maximum, and the viewer can see. You can recognize that the current time is 1 o'clock. Then, as the mask member 103 moves from the first position P1 to the second position P2, the exposure rate of the first diagram element 106a gradually decreases, so that the character "1" gradually disappears and becomes difficult to see (recognize). Immediately before the second position P2, the character "1" is almost invisible, and instead, the character "2" in the original figure begins to be visible. Then, when the mask member 103 reaches the second position P2, the exposure rate of the second diagram element 106b becomes 100%, "2" in the original figure is visualized (displayed) to the maximum, and the viewer has a current time of 2. You can recognize that it is time. This is done in the same way for other times, and the display of each time and the transition to the next time are expressed.

In this way, by using the display device for the clock, the visualized time display is maintained, and it is possible to display the state of gradually shifting to the next time while displaying the time accurately like a digital clock, so that it is an hourglass. You can feel the flow of time like this.

Further, when the display device of the present invention is used for a timepiece, the change in appearance and disappearance can be freely adjusted, so that the design value can be enhanced.

Although the display device according to the embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to such an embodiment, and various modifications and modifications can be made without departing from the scope of the present invention. Is.

For example, the shape of the mask member 3 (103) is not limited to the rectangle shown in FIG. 1 or the circle shown in FIG. 7. Further, the mask member 3 (103) may be a strip-shaped body having flexibility.

Further, a transparent protective layer or the like may be provided on the base surface 2a (102a) on which the figure element is provided. Further, in the above embodiment, the figure element is provided on the base surface 2a (102a), but the present invention is not limited to this, and is formed by laser engraving or the like inside the base member 2 (102) made of a transparent material. It does not matter if it is visible from the mask member 2 (103) side.

Further, the shape of the base surface 2a (102a) does not have to be a flat surface, and may be a cylindrical surface or a spherical surface.

When the base surface 2a (102a) is a flat surface, the moving direction (first predetermined direction D1) of the mask member 3 (103) can be translational movement, rotational movement, or a combination thereof, and the base surface. When 2a (102a) is a cylindrical surface, translational movement in the direction along the cylinder axis, rotational movement in the circumferential direction (circumferential movement), and the like are possible.

As the drive mechanism that enables the mask member 3 (103) to move in the first predetermined direction D1, a known drive mechanism can be appropriately used according to the translational movement or the rotational movement as described above. For example, an actuator such as an electric motor, a deceleration means such as a gear, and a known mechanism for converting rotary motion into linear motion can be appropriately combined.

In the above embodiment, the first stripe pattern 50 and the second stripe pattern 51 are separated from each other, but the first stripe pattern 50 and the second stripe pattern 51 may be continuously provided, and the first stripe pattern 50 may be provided. And the second stripe pattern 51 may partially overlap. Further, the mask pattern 5 may be composed of a plurality of lines or one continuous line (for example, a spiral line), and in these cases, a predetermined region portion of the mask pattern 5 may be formed. The first stripe pattern may be used, and the other area portion may be a second stripe pattern.

Further, the number of figures represented on the base surface 2a (102a) is not limited to 2 or 12, and may be any number.

In the above embodiment, the mask member (3,103) including the mask pattern (5) is arranged in front of the base member (2,102) having the optics, but the base member is a transparent member and the mask pattern is formed. Even if a base member having a figure element is placed in front of the included mask member and the figure element is set to optically interfere with the mask pattern, the same shielding complementing effect as described above can be expected. In this case, when the mask member is in the first position, the first stripe pattern is exposed from the gap of the first figure and the first figure or symbol is visualized, and when it is in the second position, the second figure element. The first stripe pattern is exposed from the gap and the second figure or symbol is visualized, and the second stripe pattern and the first figure partially overlap in the third direction, so that the first stripe pattern is partially overlapped. It is optically shielded to prevent visualization of the first figure or symbol. Then, the ratio of the first figure element overlapping the mask pattern increases as the mask member moves from the first position to the second position.
