Description

  The present invention relates to a multifunction timepiece having a function hand for displaying a plurality of information other than hours, minutes and seconds.

Conventionally, timepieces have two display modes: an analog system that displays time using two or three hands and a digital system that displays time using an electro-optical display device typified by liquid crystal or LED, or both. It is well known that it can be broadly classified into a combined combination system. In addition, among analog timepieces, for example, the user has the presence or absence of a second hand or calendar, and the presence or absence of a subordinate timekeeping function represented by a timer function, a chronograph function, an alarm function, a moon age display function, etc. It is also known that it can be selected according to the preference of the user.

Among these functions, the calendar function has a so-called perpetual calendar function that does not require the user to manually correct the date display at the end of a small month. The time information is stored in a mechanical or built-in clock circuit. It is also known that various products such as a type in which calendar information is managed by an internal counter of a circuit are provided.

  Further, as a calendar display method, a date plate or a day plate which is a disk-shaped display member is disposed between the movement and the dial, and an opening is provided at a predetermined position of the dial to show the predetermined location; In addition to the hour / minute / hour / second indicator, which is the main time information, usually arranged in the center of the watch, a pointer shorter than the hour / minute / second hand is arranged on the dial. Are roughly classified by the way this guide points. In this calendar information display method using small hands, the small hands themselves can be used as design emphasis points and can be differentiated from other products, so the display section is evenly arranged on the circumference. Various products such as a design and a design in which the display unit is arranged in a fan shape, so-called retrograde style, are provided.

  In addition, as a calendar display method for analog clocks that do not have a small hand, the dial indicating the hour, minute, or second, which is usually the main time information, is specified by an external operation such as a push button. There is a specification that displays the calendar by displaying the location. For example, Patent Literature 1 discloses an analog display timepiece in which a pointer that normally displays an hour, minute, and second is switched to a calendar display by an operation of a changeover switch. In this example, the second hand indicates the month by pressing the changeover switch, and the year is displayed with the hour and minute hands overlapping. Further, Non-Patent Document 1 discloses a clock with a specification that displays calendar information such as year, month, day, and day of the week independently with a dedicated small hand other than the hour, minute, and second hands arranged at the center of the clock. Yes.

  In addition to the normal time display, the analog display multi-function watch has various functions such as an alarm, a chronograph, a timer, and a local time display that displays a time offset by a predetermined time difference from the normal time. is there. In addition, the clock display specifications include a type in which these additional functions are displayed using a hand other than the hand that displays the time, and the hand that displays the time when a specific mode is invoked. Therefore, it is possible to roughly classify the additional functions into types that can be operated, and a wide variety of products have been put into practical use depending on the design and additional functions.

In the case of a multi-function watch equipped with these additional functions, the operation method is often such that the user calls the additional function by an external operation and selects and uses the additional function. Here, buttons and crowns are commonly used as operation members by external operation from the user, but recently, modes can be changed by touching a specific part of the bezel using a tactile sensor or mode switching by rotating the bezel. There are also clocks that can be switched.

  Here, as time information other than the hour and minute hands as main time information, there are many types such as year, month, date, day of the week, and am / pm. In order to simultaneously display these pieces of information on a wristwatch having a limited display unit, it is necessary to provide pointers corresponding to the types of information, resulting in complicated display. In addition, the time information includes information of a very long period, and a single display pointer is provided only for these displays in order to drive these pointers. A motor and train wheel are required, resulting in a larger watch. For example, when a year or a year after a leap year is displayed with a small hand, although the motor and the train wheel are required, the small hand itself is driven only once a year, so that the structure of the movement is inefficient.

  In addition, in the case of a multi-function watch that has all these calendar information and has an additional function such as an alarm, for example, the user cannot obtain additional information unless the user calls the required mode by an external operation. As it becomes very complicated.

  In order to solve these problems, an object of the present invention is to provide a multi-function timepiece that can easily display a large amount of information with a limited number of hands.

  The present invention for achieving the above object has an hour hand and a minute hand for displaying the hour and minute, and a function indicator for switching and displaying a plurality of pieces of information other than the hour, minute and second, and the current time is indicated by the hour hand and the minute hand. The time display mode in a multi-function timepiece that can be switched between a time display mode to be displayed and another mode for displaying at least one information of the plurality of information while operating differently from the time display mode. The information displayed in the other mode is displayed by switching the information displayed by the function guideline.

  In addition, switching of information displayed by the function hands in the time display mode is performed while maintaining the time display movement by the hour hand and the minute hand.

  The plurality of pieces of information include a plurality of pieces of time information having different periods. When the information displayed with the function pointer is not switched, the time information with a short period is displayed and the information displayed with the function pointer is switched. Thus, time information having a long cycle is displayed.

  The plurality of pieces of information include a plurality of pieces of time information having different periods. When the information displayed with the function pointer is not switched, the time information with a long period is displayed and the information displayed with the function pointer is switched. Thus, time information with a short cycle is displayed.

In addition, the multi-function timepiece has an operation button for switching information displayed by the function pointer, and information to be switched by the operation button is two pieces of information including first information and second information, The first information is switched from the first information to the second information by pressing an operation button, and the second information is displayed while the operation button is kept pressed, and the second information is displayed by releasing the operation button. The second information is switched to the first information.

In addition, the multi-function timepiece has an operation button for switching information displayed by the function pointer, and information to be switched by the operation button is two pieces of information including first information and second information, The first information and the second information are alternately switched every time the operation button is pressed.

  In addition, the multi-function timepiece has an operation button for switching information displayed by the function pointer, and information to be switched by the operation button is two pieces of information including first information and second information, The first information is switched to the second information for a predetermined time after the operation button is pressed, and the second information is switched to the first information after the predetermined time has elapsed. And

  Further, there are three or more pieces of information to be displayed by the function guideline, and operation buttons for switching to different information are provided corresponding to the number of pieces of information to be switched so as to display all the information. To do.

  The plurality of pieces of information may be time information other than the hour / minute / second or additional information other than the time.

  The plurality of information includes information indicating a day of the week.

  The other mode is a calendar mode, and the plurality of pieces of information include information indicating an elapsed year from a leap year.

  The other mode is an alarm mode, and the plurality of pieces of information include information indicating an alarm set state.

  As described above, according to the present invention, in the time display mode, the information displayed in the other mode is displayed by switching the information of the function pointer, so that a plurality of time information is displayed with the limited pointer. It is possible to provide a user-friendly analog multifunction clock with a calendar that allows the user to display time information and additional function information with higher priority at any time by an external operation.

  The details of the present invention will be described below with reference to the drawings.

  1 to 5 are schematic views of an embodiment of the present invention, FIG. 1 is a plan view of a completed watch, FIG. 2 is a plan view of a movement viewed from the back side, and FIG. 3 is a B button that is an external operation member. FIG. 4 is a plan view of the completed watch showing the display state of the hands when the A button 10 as an external operation member is pressed, and FIG. 5 is a watch. FIG. 6 is a flowchart showing a control flow of the circuit system.

1 to 4, 1 is a second hand as a time display member, 2 is a minute hand, 3 is an hour hand, 4 is a 24-hour hand that rotates once in 24 hours, 5 is a dial, and 6 is a dial 5 is a disk-shaped part disposed between the movement and the date plate, which is a display member for displaying the date, 7 is a day hand which is a display member for displaying the day of the week, and 8 is a function mode of the timepiece. A mode hand, 9 is a crown as a first operation member, 10 is an A button as a second operation member, and 11 is a B button as a third operation member.

In FIG. 2, 21 is a base plate which is a base material of the timepiece movement, 22 is a second motor for driving the second hand 1, 23 is an hour / minute motor for driving the minute hand 2, hour hand 3 and 24 hour hand 4, and 24 is a day hand. 7 and the day motor for driving the date board 6, 25 is a circuit board, 26 is mounted on the circuit board 25, is an IC for clocking and displaying time, or displaying various additional functions, and 27 is a circuit board 25 for the base plate 21. The circuit support plate 28, which is a holding member that is held by clamping, is a winding stem that engages with the crown 9 at one end and transmits the operation of the crown 9 to the movement correcting mechanism.

The multi-function timepiece shown in FIGS. 1 to 4 can regulate the crown 9 at three stages of the zero stage state 9, the first stage state 9a, and the second stage state 9b during normal use. The mode is a multi-function timepiece having four modes that perform different operations. The mode hand 8 disposed at the 6 o'clock position indicates which display mode the timepiece is in. In the four-mode configuration, TME indicates a normal time display mode, CAL indicates a calendar display / correction mode, ALM indicates an alarm mode, and L-TM indicates a local time mode. Further, the mode is switched by pulling out the crown 9 to the first stage position 9a and then rotating, and after the user switches to the predetermined mode, the crown 9 is pulled out to the second stage position 9b. The combination with the button 10 and the B button 11 is a specification for performing a predetermined operation such as correction.

The motor configuration is a three-motor configuration in which the second hand 1 is driven by the second motor 22, the minute hand 2, the hour hand 3 and the 24-hour hand 4 are driven by the hour / minute motor 23, and the day hand 7 and the date plate 6 are driven by the day motor 24. . Thereby, it is possible to drive the time display member comprised of all the hands and the date plate 6 by three motors.

As a display form, the second hand 1, the minute hand 2, and the hour hand 3 are provided at the center, the mode hand 8 is provided at the 6 o'clock position, the 24-hour hand 4 is provided at the 10 o'clock position, and the day hand 7 is provided at the 2 o'clock position. In addition, when the user calls a specific mode by rotating the crown 9, instead of having an alarm function or a dedicated pointer for displaying the local time, the minute hand 2, the hour hand 3 and the 24-hour hand 4 are By switching to the display corresponding to the mode, the number of pointer driving motors is reduced, and the movement size is reduced.

Side through-hole portions 25a and 25b are formed on the outer peripheral portions of the circuit board 25 corresponding to the A button 10 and the B button 11, respectively. Further, button return spring portions 27a and 27b are formed at locations corresponding to the A button 10 and the B button 11 of the circuit support plate 27, respectively. The circuit support plate 27 is electrically connected to an anode of a battery (not shown). When the A button 10 or the B button 11 is pressed, the button return spring portion 27a or 27b is connected to the side through hole portion 25a by the A button 10 or the B button. Or it contacts 25b. As a result, the side through hole portion 25a or 25b is electrically connected to the anode of the battery, so that the switch is turned on and the IC 26 performs a predetermined operation corresponding to the input. When the A button 10 or the B button 11 is released, the A button 10 or the B button 11 returns to a predetermined position by the reaction force of the button return spring portion 27a or 27b. As a result, the switch is turned off.

In FIG. 1, the day hand 7 has a fan-shaped display in which all seven day display areas 5a are indicated within an angle of about 180 ° or less, that is, a so-called retrograde display, but other than the fan-shaped day display area 5a. The surplus space side is characterized by an elapsed year from the leap year, a so-called aging display area 5b, and an alarm set state display area 5c indicating whether an alarm is set. This makes it possible to effectively utilize the surplus area of the retrograde day display area 5a without separately providing dedicated guidelines for displaying the aged display and the alarm set status, and using the day hand 7 Information can be displayed by a single pointer, that is, the day hand 7. As described above, the day hand 7 is interlocked with the date plate 6 and is driven by the day motor 24 which is a drive system different from the motor for driving the second hand 1, the minute hand 2 and the hour hand 3. Even when an alarm set state or aged display is performed, the current time is not changed or cannot be displayed.

A method for confirming the alarm set state in this multi-function watch will be described.
When checking and switching the alarm set status and correcting the alarm set time, the user rotates the crown 9 while pulling it out to the first position 9a, moves the mode hand 8 to “ALM”, and operates the alarm mode. Call. In this case, the minute hand 2, the hour hand 3, and the 24-hour hand 4 are switched from the current time display to the alarm time display by the high-speed hand movement, the second hand 1 is returned to the 12 o'clock position, and the day hand 7 is in the alarm set state display area 5c. Move to. As a result, it is possible to know whether the alarm is currently set by the day hand 7, and the alarm time set by the minute hand 2, hour hand 3 and 24-hour hand 4. By pulling out the crown 9 to the second position 9b, the operation specification is such that the alarm time is corrected and the alarm set state is changed.

  As described above, when the alarm time setting confirmation, correction, and confirmation of whether or not the alarm is set, the user pulls out the crown 9 to 9a and then rotates the crown 9 to call the alarm mode. It is possible to display the set alarm time and whether an alarm is set. However, even if it is only necessary to check whether or not an alarm is set for the time being, switching the mode every time is troublesome in operation, so this multi-function watch has a function mode of “TME” as described below. In other words, the alarm setting state can be confirmed even in the current time display mode in which the user normally uses frequently.

  In the current time display mode, the second hand 1, the minute hand 2, and the hour hand 3 move one second at the current time, and the day hand 7 displays the current day by pointing to the day of the week display area 5a. If the B button 11 is pressed in the current time display mode “TME”, the day hand 7 is moved from the day of the week display area 5a to the alarm set state display area 5c only while the switch of the B button 11 is turned on. It moves at a high speed, and displays the alarm set state, that is, whether or not the alarm is set, as shown in 7c and stops. When the user releases his / her finger from the B button 11 and the B button return spring portion 27b and the side through hole portion 25b are disconnected, the day hand 7 is rotated at a high speed again to the current day display position 7a when the switch is turned off. Return. In other words, if you want to check if an alarm is set, you can bother pulling out the crown 9 and turning it to switch the clock to the alarm mode, check the set state, and then switch back to the normal time display mode again. Even if no operation is performed, it is possible to check in the normal time display mode.

  The analog multi-function timepiece according to the present embodiment has a specification in which the day hand 7 is moved to the alarm set state display 7c by operating the B button 11 as an external operation member from the current time display mode, and the alarm set state can be confirmed. Although illustrated, for example, the specification of checking the alarm time by switching the central minute hand 2 and hour hand 3 to the display of the alarm setting time by operating the B button 11 may be possible. However, since the multi-function timepiece of this embodiment does not have a pointer for displaying the alarm time other than the central time display member, the B button 11 is used when checking the alarm set time in the normal time display mode. By pressing, it is necessary to switch the minute hand 2 and hour hand 3 from the current time to the alarm set time by high-speed hand movement, and the current time is not known during high-speed hand movement.

  Even if it is necessary to simply check the alarm set state, the minute hand 2 and hour hand 3 move at high speed each time to switch the time display state, so that current is consumed unnecessarily. In addition, since the movement of the pointer becomes complicated, the original usability may be hindered. In other words, if the current time display mode is designed to incorporate a wide variety of hand movements in spite of having a multi-function watch with an alarm mode, the ease of use of the multi-function watch with the original mode hand is lost. Because the movement of the hands and the operation specifications become complicated, the confirmation of the functions of other modes, such as the alarm in the current time display mode, is the minimum necessary function that does not hinder the display contents of the normal time display mode, that is, the alarm set A function that can only check the status is considered preferable for usability of the product.

Next, an operation method for performing aged display will be described below.
In the multi-function clock of this embodiment, regarding the calendar function, it is necessary to eliminate non-existing days (for example, April 31) by manually correcting the calendar at the end of a so-called small month that is not 31 days. However, it has a perpetual calendar function that automatically eliminates non-existing days based on the calendar data inside the IC 26, and the year and month can be displayed using the pointer.

  When the user manually corrects the calendar information, first, the crown 9 is pulled out to the first pulling position 9a, and then the crown 9 is rotated to move the mode hand 8 to “CAL” to call the calendar mode. In this case, the second hand 1 displays the month, the day hand 7 displays the current day of the week as 7a, and the hour hand 3, the minute hand 2, and the 24-hour hand 4 still display the current time. In the case of the present embodiment, the second hand 1 indicates the month by pointing the specific part of the scale formed on the dial 5 with the second hand 1. Specifically, if the second hand 1 stops at the 1 o'clock position, the calendar data inside the IC 26 means January, and if it stops at the 2 o'clock position, the calendar data inside the IC 26 means February. This makes it possible to display the month with the second hand 1.

  If the A button 10 is pressed in the calendar display / correction mode “CAL”, the day hand 7 is moved from the day display area 5a to the aged display area 5b at high speed only while the button is being pressed, and the aged display 7b is displayed. It is a specification that allows confirmation of aging. As a result, all calendar information can be displayed without increasing the motor and display pointers by switching externally, specifically by switching the display contents of the day hand 7 with the A button 10 without using another pointer for aged display. Can be displayed. In this state, the calendar information is corrected by pulling the crown 2 to the second position 2b.

  However, even if the calendar information such as age and month information is not corrected, but only to check for the time being, the crown 9 is rotated after being pulled to the first stage 9a, and the mode is changed to the calendar display / correction mode “CAL”. Since the operation is complicated to switch, this multi-function timepiece can check the month even in the current time display mode.

In the current time display mode, the second hand 1, the minute hand 2, and the hour hand 3 move one second at the current time, and the day hand 7 displays the current day of the week by pointing to the day of the week display area 5a. If the A button 10 is pressed in the current time display mode “TME”, the second hand 1 moves to the month display state 1a by high-speed hand movement and stops only while the switch of the A button 10 is conductive. At the same time, the day hand 7 moves at a high speed from the day of the week display area 5a to the aging display area 5b, and displays the aging as in 7b and stops. When the user releases his / her finger from the A button 10 and the A button return spring portion 27a and the side through hole portion 25a are disconnected, the day hand 7 is rotated at a high speed again to the current day display position 7 when the switch is turned off. Return. That is, if you want to check not only the aging but also the month, pull the crown 9 and rotate it to check the calendar display / correction mode “CAL” by switching the clock and then switch back to the normal time display mode. Even if no operation is performed, it is possible to check in the normal time display mode.
As a result, in the current time display mode “TME”, it is possible to display all time information such as aging, month, date, day of the week, and current time by an external operation, and there is an effect that the trouble of switching the mode every time is eliminated. .

In this case, the calendar display / correction mode “CAL” is substantially a dedicated mode for correcting the calendar information. However, even in the calendar display / correction mode “CAL”, the minute hand 2, the hour hand 3, and the 24-hour hand 4 are set to the calendar. Since it is not used as an information display, the current time display is continued as described above. Accordingly, even in the calendar display / correction mode “CAL”, the minute hand 2 and the hour hand 3 are provided with a time-only display clock, that is, a so-called two-hand type calendar, except that the second hand 1 stops displaying the current month. It can be used as a clock.

In the multi-function timepiece of this embodiment, the information displayed by the day hand 7 includes the day of the week and the aging, which are time information with different periods, and the A button 10 and the B button 11 in the current time display mode. When the day button is not pressed, the day hand 7 displays the day of the week, which is information with a short cycle, and when the A button 10 is pressed, it displays the aging, which is time information with a long cycle. The time information may be displayed in this order. That is, when the A button 10 or the B button 11 is not pressed in the current time display mode, the day hand 7 may display the aging and the day of the week by pressing the A button.

When displaying the day of the week with the day hand 7 when the A button 10 is not pressed, information with a relatively high frequency of use can be displayed, and when the A button 10 is not pressed, the age is displayed with the day hand 7. In this case, since the driving cycle of the day hand 7 becomes longer, current consumption can be suppressed.

Next, the circuit system operation of the multifunction timepiece of the invention will be described with reference to the drawings. FIG. 5 is a circuit block diagram of the multifunction timepiece of the present invention. In FIG. 5, the switch block 33 comprises the A button 10, the B button 11 and the crown 9 in FIG. 1, and the input state of the A and B buttons 10, 11 and the normal position of the crown 9 or The switch input control circuit 34 detects a state such as the crown rotation in the first-stage pulling state 9a, the second-stage state 9b, and the first-stage state 9a, and outputs a signal corresponding to the state. The output signal from the oscillation circuit 31 using the crystal oscillator is frequency-divided into a relatively low frequency signal by the frequency divider circuit 32, and then the second, day and hour motors are transmitted via the hand movement control circuit 35. The signals are input to a second motor drive signal forming circuit 36, a day motor drive signal forming circuit 37, and an hour / minute motor drive signal forming circuit 38 for generating a drive signal. The second motor drive circuit 39, the day motor drive circuit 40, and the hour / minute motor drive circuit 41 respectively respond to the signals supplied from the corresponding motor drive signal forming circuits 36, 37, or 38, respectively. Alternatively, the hour / minute motor 23 is driven.

The above operation will be described in detail with reference to FIG. FIG. 6 is a flowchart showing the operation of the multifunction timepiece of the invention. Starting from step S1, mode discrimination processing is performed first, and the operation state for each mode is branched. First, if it is the calendar display / correction mode, it is recognized in step S2, and the process moves to step S5 to move the hands to the current calendar display state, and depending on the setting position and rotation state of the crown 9, the calendar Processing as a calendar display / correction mode, such as an information correction operation, is performed. If the mode is the alarm mode, it is not recognized in step S2 and is judged to be in the alarm mode in the next step S3, and the process proceeds to step S6, where the alarm setting time is displayed or corrected. Alarm mode processing is performed. Similarly, in the case of the local time mode, the process proceeds from step S4 to S7, and the processing of the local time mode is performed.

Here, consider a case where the mode is the current time display mode. Similar to the mode determination and mode processing in each mode described above, the result of determination in step S8 is that the current time display mode is in effect, and processing proceeds to step S9. From this step S9 to the subsequent step S15 or step S17 is processing in the current time display mode.

  First, in step S9, it is determined whether or not the crown 9 is in the 0-step pulling position. When the B button 11 is pressed and is in the ON state, the day motor 24 is driven in step S11 to move the day hand 7 to the alarm set state display area 5c. When is not pressed and is in the OFF state, the process proceeds to step S12, and the day hand 7 is moved to the day display area 5a by driving the day motor 24 to indicate the current day position. That is, when the normal time display mode is in the normal use state, it is possible to monitor whether or not an alarm is set by the day hand 7 by pressing the B button 11. When the day hand 7 has already pointed to the position to be displayed this time by continuing the ON / OFF operation of the B button 11, the day motor 24 is not driven and the position is maintained as it is. On the other hand, when the A button 10 is pressed and turned on, this is detected in step S13, and in step S14, the second motor 22 is driven to move the second hand 1 to the month display state 1a and the day motor. The day hand 7 is moved by driving 24 to be positioned in the aged display area 5b. If the A button 10 is not pressed, the second hand 1 and the day hand 7 indicate the current second and day positions in step S16 and the subsequent step S17.

  Next, in step S18, it is determined whether or not the crown 9 is in the first-stage state 9a. However, since the crown 9 is in the 0-step pulling position when the process proceeds from step S15 or step S17. Proceeding to step S21, further, in step S21, a step for executing a function at the two-stage pulling position of the crown 9 described later, that is, a correction function is executed. The processing from S2 is repeated.

On the other hand, if the crown 9 is in the first stage state 9a, the process does not go to step S10 in step S9, but proceeds to step S18 and recognizes that the crown 9 is in the first stage state 9a and continues to step S19. move on. In this step S19, the rotation state of the crown 9 is detected, the mode is switched according to the amount of rotation, the mode to be processed next is set in step S20, and then the process returns to step S2, and thereafter set. Processing corresponding to the selected mode is executed. If the crown 9 is in the two-step pull position, the process proceeds from step S9 to step S18 but does not proceed to step S19 but proceeds to step S21. In step S21, the time correction operation is executed in the current time display mode, and the correction according to the rotation amount is performed at the two-stage pulling position of the crown 9.

Although the above mainly describes the operation in the normal time display mode in detail, the flow of processing at the first or second pulling position of the crown 9 is the same in other modes, and in the calendar display / correction mode, After the process of step S5, after the process of step S6 in the alarm mode, and further after the process of step S7 in the local time mode, in any case, after the process of each mode, the process proceeds to step S18 and the one-stage state 9a of the crown 9 In step S21, the operation of the crown 9 in each mode is performed at the two-stage pulling position.

As described above, the day hand 7 for displaying the day of the week is also used as the function hand for displaying the alarm set state and the display hand for performing the aging display, and the display is switched by external operation input in the current time display mode “TME”. As a result, a plurality of time information and additional information can be displayed within the limited display area of the dial 5 of the timepiece and by a limited number of motors without mode switching.

In the present embodiment, the specification of switching the display of the day hand 7 only while the two buttons are pressed by the external operation of the A button 10 and the B button 11 has been described, but the present invention is limited to this. Instead, for example, it is possible to specify that the display is switched only for a predetermined time, for example, 10 seconds after any button is pressed. Also, each time any button is pressed, the user can select the display of the current time display mode “TME” as the first priority information, and change this information to the normal display. For example, in the current time display mode “TME”, the day hand 7 displays the current day of the week, but if the B button 11 is pressed, the day hand 7 displays the alarm set display state even if the B button 11 is released. If the B button 11 is pressed again, the day hand 7 stops with the aged display, and if the B button 11 is pressed again, the day hand 7 returns to the current day display and stops. The specifications are as follows. That is, the specification allows the user to select the display content of the day hand 7 in the current time display mode by an external operation.
