  2. Description of the Related Art Electronic timepieces having a display unit (analog time display unit) of the current time by a pointer on a dial and another display unit (for example, a digital display unit) are in widespread use. In such an electronic timepiece, for example, when the user views the digital display unit, if the pointer is superimposed above the digital display unit, the visibility of the digital display unit is deteriorated.

  In order to solve such a problem, for example, Patent Document 1 discloses an electronic watch in which the pointer is retracted when the pointer is superimposed above the digital display unit. The electronic timepiece previously stores a plurality of positions where the hour hand and the minute hand overlap with each other as candidates for evacuation. Then, when the user performs a needle retraction operation, the electronic timepiece selects a retraction destination with the smallest retraction amount (the number of steps of the driving means) from the current positions of the hour hand and the minute hand from candidates of retraction destinations. An electronic watch is disclosed that retracts the

  In Patent Document 1, a plurality of positions where the hour hand and the minute hand overlap are considered as candidates for evacuation. However, there are only a few of these evacuation destination candidates.

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

  As shown in FIG. 1, the electronic timepiece 100 according to the embodiment of the present invention is a wristwatch having both an analog display by a pointer and a digital display. The electronic timepiece 100 is provided with two hands, a minute hand 21 and an hour hand 22 on a dial plate 20. The minute hand 21 is a long hand, and the hour hand 22 is a short hand. The minute hand 21 has an elongated shape compared to the hour hand 22. The minute hand 21 and the hour hand 22 pivot around a pivot located at the center of the dial 20.

  FIG. 2 is a block diagram showing a configuration example of the electronic timepiece 100. As shown in FIG. The electronic timepiece 100 further includes a drive unit 110, a ROM (Read Only Memory) 120, a RAM (Random Access Memory) 130, an operation unit 140, and a digital unit in addition to the dial 20, the minute hand 21 and the hour hand 22 described above. A display unit 150, a clock display unit 160 having a second hand 25, a date display unit 170 which is a date indicator, and a control unit 180 are provided.

  The drive unit 110 is configured of a plurality of stepping motors, a gear train mechanism, and the like. The drive unit 110 drives the plurality of stepping motors separately based on the drive control signal (pulse signal) from the control unit 180. The rotation axes of the minute hand 21, the hour hand 22, the second hand 25 of the time display unit 160, and the date indicator of the date display unit 170 are connected to separate stepping motors via a train wheel mechanism. Thus, the drive unit 110 separately drives the minute hand 21, the hour hand 22, the second hand 25, and the date dial. The stepping motor is configured to be rotatable in both forward and reverse directions, for example, clockwise and counterclockwise. Further, in the driving of the minute hand 21 and the hour hand 22, the rotational speed is higher in the forward direction than in the reverse direction.

  The ROM 120 is composed of a non-volatile memory such as a flash memory. The ROM 120 stores programs and data for the control unit 180 to control various functions.

  The RAM 130 is configured of volatile memory. The RAM 130 is used as a work area for temporarily storing data for the control unit 180 to perform various processes.

  The operation unit 140 includes a push-type button 23 for receiving a selection operation of a display mode and a crown 24 for time setting by manual operation. The operation unit 140 is an interface used by the user to input an instruction. As shown in FIG. 1, the button 23 and the crown 24 are provided on the side of the dial 20 respectively.

  The crown 24 is rotatable in a pulled state. The user can perform date setting by rotating the crown 24 while pulling it tight. Also, the user can adjust the time (hours and minutes) by rotating the crown 24 in a weakly pulled state. When the crown 24 is pulled, the connection between the drive unit 110, the minute hand 21, the hour hand 22, and the date dial is temporarily released, and is interlocked with the rotation by the crown 24. That is, at the time of date setting and time setting, the rotation by the drive unit 110 is in a stopped state.

  The button 23 is pressed by the user to switch and select the display mode. There are four display modes: time display mode, digital display mode, time display mode, and date display mode. In the time display mode, the normal clock function of displaying the time by the pointer on the dial 20 is prioritized, and in the display modes other than the time display mode, the other functions are prioritized.

  The digital display unit 150 is configured of, for example, a liquid crystal display (LCD), an electroluminescence (EL) display, or the like. The digital display unit 150 is used when the user selects the digital display mode, and displays digital data input from the control unit 180. The digital data is, for example, numerical data indicating timed time by a stopwatch function, a world clock, a timer, an alarm, and the like. As shown in FIG. 1, the digital display unit 150 is provided at the lower center of the dial 20.

  The time display unit 160 is provided at the upper left portion on the dial 20 as shown in FIG. The time display unit 160 has a small dial 26 with a scale (not shown) and a second hand 25. The second hand 25 rotates around the center of the dial 26 as a rotation axis. The clock display unit 160 displays clocked seconds. Although the second hand 25 is also strictly a guide, in the present specification, the second hand 25 is not included when it is referred to as a "guide".

  The date display unit 170 is provided on the right side on the dial 20, as shown in FIG. The date display unit 170 is a dated date wheel, and rotates on a rotation axis perpendicular to the rotation axis of the pointer. The date display unit 170 displays the date.

  The control unit 180 is configured of, for example, a CPU. The control unit 180 controls the overall operation of the electronic timepiece 100 by executing various programs stored in the ROM 120.

  Next, the functional configuration of the control unit 180 of the electronic timepiece 100 will be described. As shown in FIG. 2, the control unit 180 includes a mode selection receiving unit 181, a reference information acquisition unit 182, a pointer position acquisition unit 183, a determination unit 184, a retraction position acquisition unit 185, a retraction execution unit 186, a clock unit 187, and a clock. It functions as a signal generation unit 188.

  The mode selection reception unit 181 receives the display mode switching selection by pressing the button 23 of the operation unit 140, and identifies the selected display mode.

  The reference information acquisition unit 182 acquires reference information stored in the ROM 120. Here, in the present specification, the reference information is overlapped with the display area of the display unit corresponding to the display mode in which the pointer for displaying the time is selected when the display mode other than the time display mode is selected. This information is referred to when determining the evacuation position when it is determined whether or not it is determined that there is an overlap. The reference information is input by the manufacturer or the user at the time of manufacture of the electronic timepiece 100 or at the time of initialization.

  Here, the reference information will be described in detail with reference to FIGS. 1 and 3. The reference information includes, for example, a needle shape information table 191 and a display area information table 192. As shown in FIG. 3A, needle shape information of the minute hand 21 and the hour hand 22 is stored in the needle shape information table 191. Needle shape information is data indicating the length L (mm) and the width W (mm) of the pointer. The width of the pointer is the maximum width. As shown in FIG. 3B, the display area information table 192 stores data indicating the display areas of the digital display unit 150, the time display unit 160, and the date display unit 170 as a grid coordinate group.

  Here, the grid coordinate group means a set of grid coordinates. The grid coordinates are coordinates to be added to a grid obtained by finely dividing the plane on the dial 20 in the vertical and horizontal directions in FIG. The grid is, for example, a square of 0.1 (mm) x 0.1 (mm). The grid coordinates are, for example, in an orthogonal coordinate system (x, y) with the center position of the dial 20 as the origin in FIG. Indicated.

  For example, in FIG. 3B, the grid coordinate group of the digital display unit 150 has (-150, -160) ... (50, -120) and (100, -160) ... (150, -120). Two regions are shown. This is because a gap which is not a display area exists between "19:40" and "13" displayed on the digital display unit 150 in FIG. The gaps correspond to grid coordinate groups (50, -160) ... (100, -120).

  On the other hand, in the time display unit 160 and the date display unit 170, the entire area is a display area in FIG. 1 and no gap exists. Therefore, in FIG. 3B, the display area of the time display unit 160 and the date display unit 170 is only one grid coordinate group.

  In the grid coordinate group shown in FIG. 3B, for ease of understanding, among the coordinate groups of the display area, the coordinate with the smallest value of x and the coordinate with the largest value of x are representative examples. The other coordinates are omitted by "...". That is, the display area has a rectangular shape and does not indicate the coordinates of the two corner portions of the rectangular shape. For example, the display area of the time display unit 160 is circular as shown in FIG. In this case, the grid coordinate group of the display area of the time display unit 160 shows the coordinates of the left end and the coordinate of the right end of a circle as a representative example. Note that, strictly speaking, the grid coordinate group of the display area of the time display unit 160 is a grid coordinate group corresponding to a shape obtained by approximating a circle shown in FIG. 1 with a fine square grid.

  Here, the explanation of the reference information is ended, and the explanation returns to the explanation of the functional configuration of the control unit 180 of the electronic timepiece 100 shown in FIG. 2 again.

  The pointer position acquisition unit 183 acquires the current position of the hands (the minute hand 21 and the hour hand 22). The position of the pointer is the rotation angle of the pointer. The control unit 180 acquires the area currently occupied by the pointer as a grid coordinate group based on the needle shape information acquired by the reference information acquisition unit 182 and the position of the pointer acquired by the pointer position acquisition unit 183. .

  The determination unit 184 displays a display area (one of the digital display unit 150, the time display unit 160, and the date display unit 170) corresponding to a display mode in which the hands (the minute hand 21 and the hour hand 22) are selected. Determine if they overlap. The determination unit 184 compares the area currently occupied by the pointer with the display area of the display unit corresponding to the selected display mode, and determines whether the grid coordinate groups include the same coordinates. judge. If the same coordinates exist, it is determined that they overlap, and if the same coordinates do not exist, it is determined that they do not overlap.

  The retraction position acquisition unit 185 obtains the retraction position of the pointer when the determination unit 184 determines that the positions overlap. The retracted position acquisition unit 185 determines the shape of the pointer (needle shape information acquired by the reference information acquisition unit 182) and the position (rotational angle), and the display area (grid coordinates group) of the display unit corresponding to the selected display mode. And a position at which the hands (the minute hand 21 and the hour hand 22) do not overlap the display area of the display unit is determined as the retracted position.

  The evacuation position acquisition unit 185 selects a position at which the evacuation can be performed in the shortest time as the evacuation position. For example, the two nearest positions in the forward direction and reverse direction are searched from the current position, and the earlier one is selected as the save position. That is, when obtaining the retracted position, the retracted position acquisition unit 185 takes into consideration both the number of steps of the stepping motor necessary for movement and the rotational speed in the forward and reverse directions.

  The evacuation execution unit 186 executes pointer evacuation in which the pointer is evacuated to the evacuation position acquired by the evacuation position acquisition unit 185. The retraction execution unit 186 inputs a drive signal to the drive unit 110, rotates the stepping motor connected to the pointer of the drive unit 110 at a speed faster than normal, and reaches the number of steps corresponding to the target retraction position. Rotate.

  The clock unit 187 includes a counter circuit that counts the number of pulses of the clock signal of the clock signal generation unit 188. The clock unit 187 clocks the time based on the number of pulses being counted.

  The clock signal generation unit 188 includes a crystal oscillator that generates a reference clock and a variable PLL that generates a clock signal of a desired frequency from the reference clock. The frequency of this clock signal is controlled by changing the division ratio of a variable PLL (phase-locked loop).

  The configuration of the electronic timepiece 100 has been described above. Next, with reference to the flowchart of FIG. 4, a retraction control process for retracting the hands of the electronic timepiece 100 will be described.

  This process is started, for example, when the electronic timepiece 100 is started. First, when the user presses the button 23 of the operation unit 140, the mode selection receiving unit 181 of the control unit 180 receives the switching selection of the display mode (step S101).

  The mode selection receiving unit 181 of the control unit 180 identifies the selected display mode (step S102). As a result, when the selected display mode is the time display mode (step S102; No), the control unit 180 returns to step S101, and waits until the display mode switching selection is received again. If the selected display mode is a display mode other than the time display mode (step S102; Yes), the control unit 180 specifies a display unit (for example, the digital display unit 150) corresponding to the selected display mode (step S103).

  Next, the reference information acquisition unit 182 of the control unit 180 acquires reference information shown in FIGS. 3A and 3B from the ROM 120 (step S104). The pointer position acquisition unit 183 of the control unit 180 acquires the current pointer position (the number of steps of the stepping motor that drives the minute hand 21 and the hour hand 22) (step S105). Here, the control unit 180 uses the needle shape information (the needle shape information table 191 in FIG. 3A) included in the reference information acquired by the reference information acquisition unit 182, and the current position acquired by the pointer position acquisition unit 183. Based on the pointer position, the area currently occupied by the pointer is acquired as a grid coordinate group.

  The determination unit 184 of the control unit 180 includes the hands (the minute hand 21 and the hour hand 22) in the display area of the display unit corresponding to the selected display mode (for example, the display area information table 192 in FIG. 3B). It is determined whether it overlaps with the grid coordinate group of the digital display unit 150 (step S106).

  If it is determined that the determination units 184 of the control unit 180 do not overlap (step S106; No), the control unit 180 returns to step S101, and waits until the display mode switching selection is received again. When it is determined that the determination units 184 of the control unit 180 overlap (step S106; Yes), the retraction position acquisition unit 185 of the control unit 180 acquires a retraction position (step S107).

  When the evacuation position is acquired, the evacuation execution unit 186 of the control unit 180 executes evacuation processing (step S108). The retraction execution unit 186 of the control unit 180 rotates the stepping motor of the drive unit 110 forward or reverse until the number of steps corresponding to the retraction position is reached. When the save process ends, the control unit 180 temporarily ends the save control process, returns to step S101, and stands by until the display mode switching selection is received again.

  The above is the save control process. Next, an operation example of pointer retraction based on the retraction control processing will be described. In FIGS. 5 to 7 described below, the same reference numerals are given to constituent elements common to FIG.

  First, FIG. 5 is an enlarged view of the dial 20 of the electronic timepiece 100 shown in FIG. 1, and the minute hand 21 overlaps the date display unit 170 and the hour hand 22 overlaps the display area of the time display unit 160. Show the condition. In this state, when the time display mode is selected, the hour hand 22 is retracted to a retraction position which does not overlap the display area of the timing display unit 160 by retraction processing as shown by a virtual line.

  In this retraction process, the hour hand 22 is retracted in the clockwise direction. The amount of retraction (the angle at which the hour hand 22 is turned) is smaller when retracted from the current position of the hour hand 22 in the counterclockwise direction. However, since the rotational speed of the stepping motor is faster in the clockwise direction, this retraction process retracts the hour hand 22 to the retracted position in the clockwise direction. Further, since it is the time display mode that is selected, even if the minute hand 21 overlaps the display area of the date display unit 170 corresponding to the date display mode, the minute hand 21 is not retracted.

  6 and 7 show an operation example of pointer retraction when the length and the width of the minute hand 21 and the hour hand 22 of the electronic timepiece 100 are deformed. 6 and 7 assume that the positions of the hands are the same (that is, the same time).

  In FIG. 6, the minute hand 31 and the hour hand 32 have a large width and a long length, respectively. Further, since the minute hand 31 and the hour hand 32 overlap the display area of the digital display unit 150, it is difficult to see the characters.

  In this state, when the digital display mode is selected, the minute hand 31 and the hour hand 32 are retracted to the retracted positions as indicated by virtual lines by the retraction process. In particular, the minute hand 31 is retracted to a position not overlapping the digital display unit 150.

  On the other hand, in FIG. 7, the minute hand 41 and the hour hand 42 each have a small width and a short length. Although the position of the hands is the same as in FIG. 6, the hour hand 42 does not overlap the display area of the digital display unit 150 because of its short length. However, the minute hand 41 overlaps the display area of the digital display unit 150.

  In this state, when the digital display mode is selected, only the minute hand 41 is retracted to the retracted position as indicated by a virtual line by the retraction process. Further, unlike the case of FIG. 6, the minute hand 41 is retracted to a position overlapping the digital display unit 150.

  This is because the minute hand 41 is smaller in width and shorter in length than the minute hand 31 in FIG. 6, and therefore the minute hand 41 fits in the gap between the two display areas of the digital display unit 150. That is, even if the minute hand 41 overlaps the digital display unit 150 at the retracted position, the minute hand 41 does not overlap the display area of the digital display unit 150.

  Further, the minute hand 41 is retracted not to a position not overlapping the digital display unit 150 but to a gap between two display areas of the digital display unit 150 with a smaller retraction amount. Therefore, the retraction amount of the minute hand 41 is smaller than the retraction amount of the minute hand 31 in FIG. As described above, in the electronic timepiece 100 according to the present embodiment, when the width and the length of the hands (the minute hand 21 and the hour hand 22) change, the way of retreating the hands is different. The control unit 180 determines whether the pointer overlaps the display area of the display unit corresponding to the selected display mode, based on the width and length of the pointer, and determines the width and length of the pointer. This is because the retraction position is obtained based on the above.

  As described above, the electronic timepiece 100 according to the embodiment described above includes the shapes (length and width) and positions of the minute hand 21 and the hour hand 22 and the display area of the display unit (for example, the digital display unit 150) corresponding to the selected display mode. The retracting position at which the minute hand 21 and the hour hand 22 do not overlap with the display area of the display unit (for example, the digital display unit 150) is obtained based on the above, and the minute hand 21 and the hour hand 22 are I am evacuated.

  In this case, the electronic timepiece 100 retracts the minute hand 21 and the hour hand 22 to the retracted position obtained in consideration of the shapes of the minute hand 21 and the hour hand 22. Therefore, depending on the shapes of the minute hand 21 and the hour hand 22, for example, as shown in FIG. 7, it is possible to withdraw in the gap of the display area of the digital display unit 150.

  Therefore, the number of candidates that can be selected as evacuation destinations increases, and among them, the evacuation destination (evacuation position) with the smallest evacuation amount can be selected. Therefore, it is possible to suppress the useless saving amount. As a result, the time required to retract the pointer can be shortened, and power consumption can be reduced. Further, since the position not overlapping the display area of the display unit corresponding to the selected display mode is set as the retracted position, the visibility can be improved.

  Further, in the electronic timepiece 100 shown in FIG. 2, when the configuration consisting of the drive unit 110 and the control unit 180 is independently made a drive device, this drive device comprises the minute hand 21, the hour hand 22 and the digital display of the electronic timepiece 100. Even if the unit 150, the time display unit 160, and the date display unit 170 are replaced with another pointer or display unit, they can be used as they are.

  For example, even if the pointer is replaced with another pointer, if the needle shape information is input to the needle shape information table 191 of the ROM 120, pointer retraction similar to that of the electronic timepiece 100 can be realized. In addition, even if the display unit is replaced with another display unit, if the display area of the display unit is input to the display area information table 192 of the ROM 120, pointer retraction similar to that of the electronic timepiece 100 can be realized.

  Therefore, the drive device including the drive unit 110 and the control unit 180 can be used also for an electronic timepiece having pointers of various shapes and a display unit (display area), and is excellent in versatility.

  The above is the description of the embodiment. The above embodiment is an example, and the specific configuration of the electronic timepiece 100 and the contents of processing are not limited to those described in the above embodiment. So, the modification of the above-mentioned embodiment is explained hereafter.

(Modification)
In the above embodiment, with reference to the data indicating the length and width of the minute hand 21 and the hour hand 22 stored in the ROM 120, the retracted position acquisition unit 185 of the control unit 180 determines the retracted position based on these data. ing. However, the present invention is not limited to such a form. For example, instead of data indicating the length and width of the minute hand 21 and the hour hand 22, data indicating the shapes of the minute hand 21 and the hour hand 22 may be stored in the ROM 120, and the retraction position may be determined based on these data.

  Further, in the above embodiment, when the display mode other than the time display mode is selected by pressing the button 23, the electronic timepiece 100 causes the determination unit 184 of the control unit 180 to select the display mode selected as the pointer. It is determined whether the display areas of the corresponding display units overlap, and when the determination unit 184 determines that the display areas overlap, retraction of the pointer is performed.

  However, the determination of the determination unit 184 of the control unit 180 and the retraction of the hands may be executed not only when a display mode other than the time display mode is selected but also when other things are used. For example, not the switching selection of the display mode but the save instruction from the user may be triggered. In this case, the user can freely decide the timing for evacuating the pointer. Such a child clock has, for example, a button for receiving a save instruction from the user instead of the button 23, and receives a save instruction from the user instead of the mode selection receiving unit 181 of the control unit 180. Equipped with

  In the above embodiment, the data indicating the display area of the digital display unit 150, the time display unit 160, and the date display unit 170 is a grid coordinate group as shown in FIG. 3 (B). However, the data indicating the display area of the display unit is not the grid coordinate group but the grid coordinates at the center position and the vertical dimension (length in the y-axis direction) and the lateral dimension (length in the x-axis direction) Good. However, in this case, even if the actual display area is circular as in the time display section 160, the display area is data indicating a rectangular shape, and therefore, it is applied only when there is no circular display section. preferable.

  In the above embodiment, the position of the pointer is the rotation angle of the pointer. However, the number of steps of the stepping motor driving the pointer is not limited to the rotation angle of the pointer, or the rotation angle of the pointer is converted from the number of steps of the stepping motor driving the pointer, It may be a rotation angle obtained by the conversion.

  In the above embodiment, the maximum width is used as data indicating the widths of the minute hand 21 and the hour hand 22 included in the needle shape information table 191 of the ROM 120. However, not only the maximum width but also an average width may be used. Moreover, since it is most preferable that the data indicating the widths of the minute hand 21 and the hour hand 22 is the maximum width in a portion overlapping the display area of the display unit, data indicating such widths may be used. In addition, since the portion where the minute hand 21 and the hour hand 22 overlap the display area of the display unit is hardly in the vicinity of the base of the pointer, the width may be determined excluding such a portion.

  Although the reference information is stored in the ROM 120 in the above embodiment, the present invention is not limited to this. For example, reference information may be stored in the RAM 130.

  In the above embodiment, grid coordinates are indicated by orthogonal coordinates (x, y), but a distance R from the center of the dial 20 as an origin and an angle θ with respect to an axis from the origin toward the 3 o'clock direction , And may be shown in polar coordinates (R, θ). The actual operation amount in the retraction process is the turning angle of the pointer (the number of steps of the stepping motor driving the pointer). Therefore, when using polar coordinates for grid coordinates, it is advantageous in that the angle θ indicated by the grid coordinates can be directly compared with the rotation angle which is the operation amount.

  In the above embodiment, the display mode is classified into four types: a time display mode, a digital display mode, a time display mode, and a date display mode. However, the present invention is not limited to this. In addition to the time display mode, one or more display modes corresponding to the display unit may be provided.

  Although the preferred embodiments and modifications of the present invention have been described above, the present invention is not limited to the specific embodiments, and the present invention includes the inventions described in the claims and the equivalents thereof. Range is included. In the following, the invention described in the original claims of the present application is appended.
