Definitions

  • the present invention relates to an analog electric timepiece having a date indicator or a day indicator.
  • FIG. 3 A first example of a conventional analog electric timepiece indicating forenoon/afternoon is shown in Figure 3.
  • a motor 5 drives hour and minute (and second) hands 7, an AM/PM hand 8, which indicates forenoon/­afternoon, and a date indicator or a day indicator 4, via respective gear trains 6, 61 and 62.
  • the AM/PM hand 8 may be one that indicates the time on a twenty four hour scale.
  • FIG. 4 is a block diagram of a second example of an analog electric timepiece that indicates forenoon/­afternoon.
  • a second motor (2) is additionally provided to drive the AM/PM hand 8, and is independently driven.
  • the presence of the AM/PM hand 8 or the twenty four hour scale hand inevitably imposes limitations on the design, making it difficult to obtain a simple design like that of an ordinary analog timepiece.
  • the AM/PM hand 8 and the other hands are mounted at the centre of a time­piece dial, furthermore, there may exist a total of four hands mounted at the centre, namely second hand, minute hand, hour hand and AM/PM hand 8.
  • the axial height of the hands tends to increase, and it becomes difficult to read the time when the hands overlap one another.
  • the hands have to be moved to appropriate positions, which takes twice as long as in an ordinary timepiece due to the presence of the AM/PM hand 8.
  • the timepiece design may be made relatively simple when a twenty four hour scale hand is employed instead of the ordinary hour hand. However, for people who are accustomed to twelve hour analog timepieces, the twenty four hour analog timepiece is very inconvenient to read.
  • an analog electric timepiece comprising a first motor for driving time indicating means by way of a first gear train, a second motor for driving day or date indicating means by way of a second gear train, and characterised by means for indicating forenoon and afternoon arranged to provide an indication in synchronism with an indication provided by the day or date indicating means.
  • the date indicator or the day indicator bears letters or marks to indicate the forenoon and the afternoon.
  • a date window or a day window is formed in a dial of the timepiece for displaying the day of the month or the day of the week inscribed on the date indicator or the day indicator and for indicating also the letters or marks representing the forenoon and the afternoon.
  • letters or marks indicating the forenoon and the afternoon may be written on the dial near the date window or the day window.
  • AM/PM window a window separately from the date window or the day window for indicating the forenoon/afternoon separately from the date or the day.
  • an additional AM/PM indicator or AM/PM hand arranged to rotate together with the date indicator or the day indicator by way of an appropriate gear train.
  • the AM/PM indicator in the form of a dial or the hand is coupled to a gear train of the same series as the gear train coupled to the date indicator or the day indicator so as to rotate in correspondence with the date indicator or the day indicator.
  • the date indicator or the day indicator or the forenoon/afternoon indicator is conveniently driven by the second motor, which is controlled by an intregrated circuit.
  • the integrated circuit there are preferably set in advance the number of steps of the motor per day calculated from the gear train ratio from the motor to the date indicator, day indicator or fore­noon/afternoon indicator, and the number of steps for switching the forenoon into the afternoon calculated from markings on the forenoon/afternoon indicator for indicating the forenoon/afternoon.
  • the motor is then controlled as required.
  • the motor needs to generate a movement of ( m - n ) steps when the day changes from 11:59 PM midnight to 12:00 AM, and a movement of n steps when the time changes from 11:59 noon to 12.00 PM.
  • the motor should generate a movement of (2 m - n ) steps when the day changes from the end of a month with thirty or less days (except February) into the first of the next month. Even when it is desired to indicate other time information (alarm time, time of other cities, etc) using the hour and minute (and second) hands, the motor should be controlled on the same basis.
  • the invention may be applied to a timepiece without increasing the number of parts or imposing a limitation on design, and, further, without resulting in an increased amount of time being required for moving the hands of the timepiece when the mode is to be changed to display other time information.
  • a first motor 5 drives hour and minute (and second) hands 7 via a first gear train 6, and a second (separate) motor 2 drives a date indicator or a day indicator 4 via a second gear train 3.
  • An integrated circuit 1 drives the first motor 5 after every elapse of a pre-determined period to drive the hour and minute (and second) hands, and, at the same time, counts the hours, minutes and seconds.
  • the following two methods have been proposed to bring the hours, minutes and seconds counted by the integrated circuit 1 and the positions of the hour and minute (and second) hands 7 into agreement with each other.
  • a hand positioning condition (hereinafter referred to as 0 match mode) is set, the hands are set to pre-determined positions (e.g. the twelve o'clock position) by the user in the 0 match mode, and then the timepiece is used.
  • the integrated circuit 1 must count the positions of the hour and minute (and second) hands at all times. That is, every time when the motor 5 is driven, the count is increased by +1 or -1 (when reversely rotated).
  • means are provided to detect the positions of the hour and minute (and second) hands. That is, the positions of the hands are detected e.g. by optical sensors, magnetic sensors, or electric contacts.
  • the forenoon/afternoon is to be indicated simply by the date indicator or the day indicator, the moment when the hour hand passes the twelve o'clock position needs simply to be detected.
  • the present invention is not simply to indicate the forenoon/afternoon, but is to realise easily functions such as a twenty four hour scale, alarm and world times based upon the forenoon/afternoon indications.
  • the positions of the hour and minute (and second) hands must be counted by the integrated circuit 1 during the period from one detection to the next, as in the method employing the 0 match mode, despite the provision of hand position detecting means.
  • the integrated circuit 1 controls the second motor 2 to indicate the day of the month, the day of the week and the forenoon/afternoon.
  • a 0 match mode or position detecting means in order to bring the contents of the day of the month, day of the week and forenoon/afternoon counted by the integrated circuit 1 into agreement with the position of the date indicator or the day indicator 4.
  • Figure 1 shows the case of the 0 match mode.
  • Figure 2 illustrates a second embodiment of the present invention.
  • the first motor 5 drives the hour and minute (and second) hands 7 via a first gear train 6, and the second (separate) motor 2 drives an AM/PM dial or hand 8 via a second gear train 3 and further drives a date indicator or day indicator 4 via a third gear train 9.
  • the integrated circuit 1 operates in the same manner as in the case of Figure 1.
  • the AM/PM dial or AM/PM hand 8 may be freely arranged inside the timepiece.
  • FIG 5 shows a first example of a day indicator employed in the present invention.
  • the day indicator 40 has an AM mark 44 and a PM mark 45 written in front of and behind the day 42 of the week.
  • the day 42 and the AM mark 44 together are indicated through a day window as shown in Figure 5 (A).
  • the time to be indicated is after noon, the day 42 and the PM mark 45 are indicated as shown in Figure 5 (B).
  • FIG 6 shows a second example of a day indicator employed in the present invention.
  • the day indicator 40 has an AM mark 44 and a PM mark 45 positioned to the right and the left sides of the day 42 of the week.
  • the day 42 and the AM mark 44 indicating the letters AM are shown together in the day window as illustrated in Figure 6 (A).
  • the PM mark 45 indicates the letters PM on the dial as shown in Figure 6 (B).
  • Figure 7 shows a first example of a date indicator employed in the present invention.
  • AM/PM marks 46 over and under the day 43 of the month.
  • the day 43 and the AM/PM mark 46 are exposed together through the date window as shown in Figure 7 (A), the AM/PM mark 46 indicating the letters AM on the dial.
  • the AM/PM mark 46 indicates the letters PM on the dial as shown in Figure 7 (B).
  • Figure 8 shows a second example of a date indicator employed in the present invention.
  • the date indicator 41 has an AM mark 44 and a PM mark 45 put to the upper right and the lower left of the day 43 of the month.
  • the day 43 and the AM mark 44 are exposed through the date window as shown in Figure 8 (A).
  • the PM mark 45 is exposed through the date window as shown in Figure 8 (B).
  • Figure 9 is a plan view showing the coupling between the date indicator 4 and the separate motor 2 in the present invention.
  • the date indicator or the day indicator 4 can be continuously rotated by the driving motor 2 via the second gear train 3, whereas the date indicator and the day indicator used for an ordinary analog timepiece are arranged to operate intermittently only once every day.
  • the date indicator and the day indicator 4 move continuously in correspondence with the rotation of the driving motor 2.
  • the number of steps ( n steps) for switching the fore­noon to the afternoon should be determined depending upon the design of the AM/PM mark 46 and the like and of the date indicator or the day indicator.
  • the date indicator or the day indicator 4 can also be rotated reversely.
  • FIG 10 is a block diagram illustrating the structure of the integrated circuit 1 of the timepiece according to the present invention.
  • oscillation means 10 sends a reference signal to frequency dividing means 11, and timing signal generating means 12 generates timing signals for a variety of calculations and instruction executions upon receipt of output signal groups from said frequency dividing means 11.
  • Signals from the timing signal generating means 12 are received by read only memory means 13 (hereinafter referred to as a ROM), in which the operating procedure has been programmed and are further received by calculation means 14 (hereinafter referred to as a CPU), which decodes instructions of the ROM and performs various computations and input/­output operations.
  • a data bus 19 random access memory means 15 (herein­after referred to as a RAM), which stores time, date and hand position data, switch input means 18, and motor drive means 16 and 17.
  • RAM random access memory means 15
  • An output signal of the timing signal generating means 12 determines an address of the ROM 13 for supplying programming data to the CPU 14, which decodes the programming data that is sent thereto, processes the data stored in the RAM 15 and processes the data that is to be given to the motor drive means 16 and 17.
  • the CPU 14 senses this input and performs the processing according to the operating procedure programmed in the ROM 13.
  • Figure 11 is a block diagram showing the ROM 13 and the RAM 15 in detail.
  • the forenoon/afternoon display by the date indicator or the day indicator is realised by programming forenoon -> afternoon processing means 131 and afternoon -> forenoon processing means 132 in the ROM 13.
  • the ROM 13 consists of time counting processing means 130, the forenoon -> afternoon processing means 131, the afternoon -> forenoon processing means 132, time correcting processing means 133, date/day correcting processing means 134 and 0 match processing means 135.
  • the forenoon/afternoon is displayed using the date indicator, and the hands consist of an hour and a minute hand, the minute hand being driven after every ten seconds.
  • the RAM 15 consists of a portion 150 for storing the hand positions, a portion 151 for storing time data, a portion 152 for storing date or day indicator position, and a portion for storing the date or day.
  • the hand position memory unit 150 consists of a hand position counter for counting the values 0 to 4319.
  • the time data memory unit 151 consists of a one second counter for counting the values 0 to 9, a ten second counter for counting the values 0 to 5, a minute counter for counting the values 0 to 59, and an hour counter for counting the values 0 to 11.
  • the forenoon/afternoon memory unit 152 consists of a forenoon/afternoon counter for counting the values 0 to 1.
  • the date indicator position memory unit 153 consists of a date indicator position counter for counting the values 0 to ( m x 31) - 1.
  • the date memory unit 154 consists of a date counter for counting the values 1 to 31. Since the time of twelve hours is counted with ten seconds as a unit, the counter needs to be capable of counting 12 x 3600 (seconds) / 10 (seconds) 4320. When the number of steps of the date indicator is m steps per day, the date indicator position counter needs to be capable of counting m x 31.
  • Figure 12 shows the appearance of the timepiece according to the present invention, displaying the hour and minute hands 7 driven by the first motor, and the day 43 of the month and AM/PM mark 46 of the date indicator 4 through the date window.
  • Switches A, B and K are used to correct the time and to effect 0 matching.
  • FIG 13 is a flow chart representing a process start portion of the operation performed in the integrated circuit of the present invention. Under a halt condition, the integrated circuit 1 starts the program upon a switch input and a 1-Hz interrupt. In Figure 13, a judgement is made as to whether there is a switch input (step 1) or the 1-Hz interrupt (step 3) just after the program is started, the process branching to switch input processing (step 2) and to 1-­Hz processing (step 4), respectively.
  • FIGs 14 (A) and 14 (B) are flow charts representing the 1-Hz processing according to the present invention.
  • this processing is executed in response to the 1-Hz interrupt.
  • the one second counter in the RAM 15 is then increased by +1 (step 5), and the program branches to halt (step 6) when the count value of the one second counter is not 10.
  • the counter is set to 0 (step 7) and the first motor is driven by one step (step 8) to advance the minute hand by ten seconds.
  • the hand position counter is increased by +1 (step 9) and whether its count value is 4320 or not is checked (step 10).
  • the hand position counter is set to 0 (step 11 ).
  • the ten seconds counter, minute counter, hour counter and forenoon/­afternoon counter are processed in the same manner (steps 12 to 23).
  • the second motor is driven by ( m - n ) steps (step 24) and the date indicator position counter is increased by ( m - n ) (step 25).
  • the second motor is driven by n steps (step 26), and the date indicator position counter is increased by n (step 27).
  • Whether the date indicator position counter exceeds m x 31 or not is then checked (step 28).
  • the date indicator position counter is decreased by ( m x 31) when the above value is exceeded (step 29).
  • the foregoing describes the 1-Hz processing in an ordinary mode.
  • the number m of steps of the date indicator per day and the number n of steps from the forenoon to the afternoon should be determined by the reduction ratio of the second gear train 3 and the design of the date indicator.
  • FIGS 15 (A) and 15 (B) are flow charts representing switch input processing according to the present invention. This processing is executed in response to the switch input.
  • the mode is divided into three, i.e. an ordinary mode, a time correction mode, and a 0 match mode (step 30).
  • the switch exhibits no function and the process passes to halt.
  • the program branches into four depending upon the switch that is depressed (step 31).
  • the switch A When the switch A is depressed, the time is advanced by one minute and the program jumps to the step 14 of the 1-Hz processing.
  • the switches A and K are simultaneously depressed, the time is advanced by one hour, and the program jumps to the step 18 of the 1-Hz processing.
  • the switch B When the switch B is depressed, the date is advanced by one day and the program jumps to step 32, and when the switches B and K are simultaneously depressed, the date is advanced by seven days and the program jumps to step 34.
  • the second motor is driven by required amounts respectively (steps 32, 34), and the date indicator position counter is increased by corresponding amounts (steps 33 and 35).
  • step 36 Whether the date indicator position counter is in excess of m x 31 or not is next checked (step 36), and the date indicator position counter is increased by -( m x 31) (step 37) when the above value is exceeded.
  • the program also branches into four depending upon the switch that is depressed (step 38).
  • the switch A When the switch A is depressed, the hand is advanced by one step (corresponding to ten seconds) by driving the first motor by one step (step 39).
  • step 39 The same processing is carried out when the switches A and K, B, and B and K are depressed (steps 40 to 42).
  • the motors are only driven but the contents of the hand position counter and the date indicator position counter are not changed since this is the mode to bring the motor positions, hand positions of the RAM and the content of the date indicator position counter into agreement with one another, unlike the ordinary mode or the time correction mode.
  • the date indicator or the day indicator is driven by a separate motor in order to display the forenoon/afternoon.
  • the analog electronic timepiece displays the forenoon/afternoon without imposing the previous limitation on the design and, hence, easily realises the specifications that could not be realised so far due to such design limitation.
  • the forenoon/afternoon display is suitable for timepieces having such specifications as alarm, world time, perpetual calendar, and the like.
