## Abstract

An electronic analog timepiece with hour and minute hand driven by a stepping motor in accordance with low frequency timekeeping signals supplied by a high frequency quartz time reference. The electronic time-setting control circuit is controlled by a single manual push-button switch. The time is adjusted for correction, daylight saving or time zone change at slow, fast and accelerated rate in the clockwise and counterclockwise directions. Both an automatic single hour time correction with automatic restart, and a manual restart option are incorporated.

## Background
This invention relates generally to electronic timepieces, particularly quartz analog wristwatches. As is well known in the art, these include a quartz controlled oscillator supplying high frequency time reference signals to a countdown divider chain, which ultimately provides low frequency time keeping signals of great accuracy. These timekeeping signals actuate a drive circuit providing drive pulses of a selected wave shape to drive a stepping motor which turns hour, minute and sometimes second hands through a gear train. These drive pulses may be repetitive wave shapes of the same polarity for driving stepping motors of the type shown in U.S. Pat. Nos. 3,818,690 issued to Schwarzschild or 4,070,279 Oudet et al issued Mar. 14, 1978. Alternately, the stepping motor may be of the type receiving pulses of alternating polarity as described in U.S. Pat. No. 4,112,671 Kato et al issued Sept. 12, 1978.

It is further known that time correction of such a timekeeping circuit may be effected by supplying sources of different wave shapes or polarities to reverse the direction of the stepping motor so as to drive the hands counterclockwise, and that the movement of the hands can be speeded up and driven at various speeds in both the forward and reverse directions. Examples of the foregoing electronic timesetting circuits are shown in German Pat. No. 2,025,710; U.S. Pat. No. 4,173,863 Motoki et al issued Nov. 13, 1979; U.K. pat. No. 1,557,145 (Daini Seikosha); and U.S. Pat. No. 4,030,283 Sauthier et al issued June 21, 1977.

It is also known to use a single pushbutton switch for controlling various timesetting modes, this being illustrated in the assignee's U.S. Pat. No. 3,953,964-Suppa et al issued May 4, 1976 for a digital electronic watch, and the aforesaid U.S. Patents to Sauthier et al and to Motoki et al. An arrangement using a single pushbutton to achieve alternating forward and backward hand movement for time correction is disclosed in U.S. Pat. No. 4,192,134 issued Mar. 11, 1980 to Yoshida.

One problem associated with setting a quartz analog stepping motor watch is that, if the watch has been previously accurately set in accordance with a time standard signal, and it is desired to change the hour hand reading by exact increments of one hour for daylight saving change or time zone change, without disturbing the watch timekeeping, prior art devices do not adequately supply this defficiency.

The aforesaid U.S. Pat. No. 4,173,863 to Motoki provides for time correction of one hour but the watch must be reset by advancing the hands at a slow rate after this.

Another problem in the prior art is that it is sometimes desired to move the hands slowly in order to position them accurately for a manual restart from a time standard signal. However, if it is necessary to move the hands a great distance, this slow motion is tedious and time consuming. Therefore, it would be desirable to have an accelerated forward speed as well as other forward and reverse speeds effectuated, however, through a single pushbutton control.

Accordingly, one object of the present invention is to provide an improved electronic timesetting device for an electronic analog timepiece which automatically corrects the time in exact one hour increments with a single pushbutton control without affecting timekeeping.

Another object of the invention is to provide, in such a timepiece, an improved electronic timesetting circuit, having both slow and fast setting speeds, both forward and reverse with manual restart.

The invention both as to organization and method of practice, together with further objects and advantages thereof will best be understood by reference to the following specification, taken in consideration in the accompanying drawings in which:

FIG. 1 is a simplified schematic diagram of the main components of a quartz analog electronic timepiece,

FIG. 2 is a plan view of a quartz analog wristwatch utilizing the invention,

FIG. 3, 4 and 5 are diagrams illustrating forward and reverse time correction of the minute hand,

FIG. 6 is block diagram showing the multiple time correction modes available in the preferred embodiment of the invention, and

FIG. 7 is a logic diagram illustrating the control circuit.

Briefly stated, the invention is practiced by providing a special electronic control circuit in an electronic analog stepping motor timepiece of the type having a time standard providing periodic high frequency signals, a frequency divider providing periodic low frequency signals, and a plurality of trains of periodic intermediate frequency signals, a manual time correcting switch, a reversible stepping motor adapted to drive the hands of a timepiece in response to forward and reversing pulse wave shapes, and a drive circuit connected to supply the wave shapes to the stepping motor. The control circuit is responsive to the low frequency and the intermediate frequency signals from the divider and, in accordance with the operation of the manual switch, corrects the time in multiple modes in various forward and reverse speeds with automatic or manual restart.

In the preferred embodiment, forward and reverse correction in exact one hour increments with automatic restart is provided, with the proper compensation for the time used in making the correction in either direction. Slow and fast speeds in forward and reverse, and accelerated forward speed with manual restart are provided. Automatic switching between slow and fast speed after a preselected number of slow pulses, and automatic restart after a preselected number of fast pulses are provided by special counters incorporated into the control circuit.

Referring to FIG. 1 of the drawings, a time standard source of high frequency signals is provided by means of oscillator 1 controlled by a quartz crystal 2 supplying a 32.768 kHz signal to a divider count down chain 3. The divider 3 is a series of conventional flip-flop stages each dividing the frequency by a factor of two and ultimately providing a low frequency signal f at the output on lead 4. Divider 3 is also arranged to provide a plurality of trains of intermediate frequency signals of progressively higher frequencies f1, f2 and f3 on leads 5, 6, 7 respectively. These are supplied, along with the low frequency signals f to a time correcting control circuit 8. A manual time correcting pushbutton switch 9 is also connected to the control circuit. Control circuit 8 supplies a series of stepping pulses at normal, slow, fast or accelerated frequency over lead 10 and a reversing signal over lead 11 to a conventional stepping motor drive circuit 12. The drive circuit 12 provides pulses of a suitable wave shape for forward or reverse operation of a conventional reversible stepping motor 13. The latter drives the hands of the timepiece through a conventional gear train.

FIG. 2 of the drawing illustrates a quartz analog wristwatch 14 with hour and minute hands 15, 16 and a pushbutton 17 in place of the conventional watch crown. In order to prevent inadvertent actuation, pushbutton 17 preferably has a low profile or may be fully recessed, if desired, with an indentation for actuation by a pointed instrument such as a ballpoint pen.

The detailed logic diagram for the control circuit 8 is shown in FIG. 7 enclosed in dot-dash lines. Inputs to the control circuit from divider 3 comprise a 1/15 Hz signal on lead 4 comprising the low frequency signal f. Intermediate frequency signals f.sub.1, f.sub.2 and f.sub.3 are supplied by a first intermediate frequency signal of 2 Hz on lead 5, a second intermediate frequency signal of 16 Hz on lead 6, and a third intermediate frequency signal of 64 Hz on lead 7.

The output signals from control circuit 8 to the drive circuit 12 comprise a stepping motor pulse rate signal supplied on lead 10 and a reversing signal on lead 11. The pushbutton 9 operates and selectes the "program" in which the control circuit functions.

The logic diagram of FIG. 7 illustrates the preferred embodiment of a control circuit in terms of conventional logic elements, including AND and OR gates, D type flip-flops, and decade counters which can be implemented with any desired type of logic system. Preferably the logic of the control circuit 8 is carried out on an integrated circuit chip, along with appropriate circuit elements of oscillator 1, divider 3 and drive circuit 12, in a manner which is well known to those skilled in the art. Various "programs" of time correcting sequences are initiated in control circuit 8 by means of the single pushbutton 9, depending upon the time correcting program desired (see Table 3). Four different stepping motor pulse rate signals are provided by the frequency divider and according to the selected program the logic switches of the control circuit select the proper pulse frequency and counters count the number of pulses to carry out the program. In accordance with the foregoing elements, slow, fast, accelerated pulse trains for either forward or reverse hand correcting movement may be provided to the stepping motor in lieu of the normal (or low frequency) pulse signals.

The major logic elements comprise flip-flops A through J, counters L through M and gates 21 through 35. The functions of the flip-flops, counters and gates will be explained in detail, but are conveniently summarized in following Tables 1 and 2. __________________________________________________________________________ F/F No. FUNCTION      TRIGGERED BY RESET BY       PROGRAM __________________________________________________________________________ A    Reverse stepping motor.

The selected program and speed of the stepping motor is controlled by logic switching means comprising flip-flops A-J in conjunction with gates 21-35. Flip-flop A has an output connected to lead 11 which reverses the stepping motor. Flip-flop A has an input connected to one of the outputs of flip-flop B through a gate designated by reference number 50, which also has inputs from flip-flop C and gate 31. Flip-flop B has an input connected to an output of flip-flop D through an OR gate 51. Flip-flop D has an input connected to the pushbutton 9 via an inverter 52, so that the outputs of flip-flop D indicate the position of the pushbutton. The logic is arranged so that a logic high signal appears on lead 47 when the pushbutton is pressed and a logic high signal on lead 48 when the pushbutton is released. The Q outputs of flip-flops B and D are connected to an input of flip-flop C through an OR gate 53.

Flip-flop E, which controls the normal watch running speed has its input connected to lead 47. Flip-flop F, which controls the accelerated stepping motor speed V3 has its clock input connected to the output of gate 34 measuring the fourth counter impulse and its D input connected to the Q output of flip-flop C.

Flip-flop G, which serves to measure the end of a one hour time zone change has a clock input connected to the output of gate 32 measuring the 242 second counter pulse and has its output connected to the reset terminal of flip-flop E via an OR gate 54. Flip-flop H which controls the transition between slow and fast speed setting, has its clock input connected to gate 33 measuring the 34th counter inpulse and an output connected to the reset of flip-flop C via an OR gate 55.

Flip-flop I has an input connected to the lead 48 so as to receive an inpulse when a pushbutton is released, and flip-flop J is also connected to lead 48 via an AND gate 56. An output of flip-flop J is connected to an input of flip-flop I.

The rate of the stepping motor is determined by the frequency of pulses gated by OR gate 27 having four inputs. The inputs are furnished by the outputs of the AND gates 23, 24, 25 and 26. AND gate 23 has one input connected to lead 7 from the frequency divider and the other input connected to flip-flop F. AND gate 24 has one input connected to lead 6 and the other input connected to flip-flop H. AND gate 25 has one input connected to lead 5 from the frequency divider and the other input connected to the output of gate 21. AND gate 26 has one input connected to lead 4 and the other output connected to flip-flop E. The gates 23, 24, 25, 26 and 27 comprise first gating means furnishing normal, slow, fast and accelerated stepping pulses to the drive circuit 12. The gates 31, 32, 33, 34 and 35 comprise second gating means connected to selected counter outputs.

Certain resetting functions are provided by gates connected to the output of flip-flop E on a lead 57, which is connected to the input of OR gate 55, the reset terminal of flip-flop A and to the input of OR gate 22. The output of OR gate 22 is connected to the reset terminal of flip-flop B and to the reset terminal of flip-flop J via OR gate 58.

Another resetting of the counters K, L and M accomplished via the output of OR gate 30 having as one input OR gate 29 and the other input OR gate 22. OR gate 29, in turn, has one input connected to flip-flop I and the other input connected to a lead 59 from flip-flop F.

The final counter of the frequency divider is designated by reference numeral 60. This counter has a reset terminal connected to the output of an AND gate 28 which has one input connected to flip-flop I, the other input connected to lead 47.

The flip-flops and gates of control circuit 8 comprise logic switching means arranged to carryout the various time correction programs set forth in Table 3. The logic switching means also determine which program is activated by means of flip-flop devices actuated both by the position of pushbutton 9 and timing counts from the counters, as well as various logic conditions supplied by other gates and flip-flops. Reference to tables 1 and 2 will supply the necessary understanding of the functions of the various elements in the logic switching circuits.

Decade counters K, L, and M are connected in series. The input to counter K is supplied by an inverter 40 connected to the output of OR 27. The decade counters are resettable by signals on a lead 41 and having outputs connected as noted to AND gates 31, 32, 33, 34, 35. Assuming the counters are all reset, they count the number of pulses received from inverter 40 and provide an output on the number of pulses indicated in parenthesis next to the respective AND gates 31-35. In other words, gate 33 decodes an input count of 34 pulses supplied by the output values "0", "3" and "4" from counters, M, L, K respectively. The number of pulses counted is independent of the frequency of the pulses received at the input of counter K. Therefore the pulse counts are at the low frequency f or any of the intermediate frequencies f1, f2, f3. These serve to provide time delays and to count a preselected number of pulses at different time setting speeds.

Pushbutton 9 is connected to the input of the flip-flop D which is clocked by negative transition of the 16 Hz signal on lead 42 when pushbutton 9 is pressed, provided that AND gate 43 is enabled. The pushbutton also resets the flip-flop D when the pushbutton is released, provided that AND gate 44 is enabled. Gates 43 and 44 are enabled by a signal on lead 45 connected to the output of normal speed pulse AND gate 21 via inverter 46. Thus, there is a logic 1 signal from the Q output of D connected to lead 47 when the pushbutton is pressed, and a logic 1 signal at the Q output of D connected to lead 48 when the pushbutton is released. One push causes output from D and C and, provided that gate 21 is enabled by F, speed V1 is commenced by gate 25. Release of the pushbutton provides an output from B to gate 50; a second push causes output from C to gate 50 and if this occurs within one second, gate 50 is enabled by a pulse from gate 31 (2 pulses to counter K). Flip-flop A will reverse the motor and commence counterclockwise rotation.

Holding the pushbutton down more than three seconds initiates a different program. One push causes flip-flop C to provide an output to flip-flop F. The fourth impulse (gate 34) then switches F which enables gate 23 and causes the motor to step at an accelerated speed of 64 Hz pulses. Release of the pushbutton resets F and enables gate 21 to recommence slow speed V1. Another push during speed V1 followed by release of the button causes flip-flop I to stop in the stepping motor. Another push resets E to resume normal speed and also enables gate 28 to reset counter 60.

Referring to FIGS. 3, 4 and 5 of the drawing, diagrams are illustrated of the speed movement of the minute hand from its starting position designated as 100, 101, 102 in FIGS. 3, 4 and 5 respectively. Prior to correction, the minute hand is moving at speed V0. The starting position may be in any location at the time when correction is commenced, as directed. In one forward setting mode, (FIG. 3) the minute hand advances clockwise at a speed V1 for a preselected number of pulses (determined by the counters K, L and M) until it reaches a position 103 relative to the initial position 100. Thereafter it advances at a fast time correcting rate V2 until it reaches a final position 104, which is just enough beyond the starting position 100 to compensate for the time it has taken to advance the hands by an increment of one hour. Therefore, in this case, in order for the timesetting of the minutes not to be disturbed, the number of pulses selected is 242-240 for the one hour advance, and 2 pulses more to advance the time by 30 seconds for the time to carry out the correction as follows: 34 pulses at V1 requires 17 seconds 208 pulses at V2 requires 13 seconds 242 pulses          30 seconds for correction time. ______________________________________

The reverse or counterclockwise steps are illustrated in FIG. 4. Initiation of time correction in the counterclockwise direction commences from an initial position of the minute hand 101, first clockwise for 2 pulses at V1 speed to position 105, then in reverse at speed VR1. After moving a preselected number of steps, to a relative position, 106, the minute hand moves at a fast time correcting speed VR2 until it reaches a find position 105. Position 105 is located 30 seconds beyond starting position 101 to compensate for the exact time consumed in the time correcting process, as follows: 2 pulses at V1 requires 0.5 sec. 32 pulses at VR1 requires 16.5 sec. 208 pulses at VR2 requires 13.0 sec 242                 30 seconds for correction time. ______________________________________

In accordance with one aspect of the invention, it should be noted that the total number of pulses to the stepping motor, as measured by counters K, L, M is the same in both cases, i.e., 242, regardless of the direction of hand movement. However, the net movement of the hand from start to finish, in order to compensate for correction time, must be more than one complete revolution for clockwise correction and less than one complete revolution for counter clockwise direction, because the hand is moving opposite that of time telling movement. This problem is solved with the present invention by the expedient of moving for a short time in the clockwise direction before reversing, as shown in FIG. 4. This is summarized below. CLOCKWISE         COUNTERCLOCKWISE ______________________________________ +34   steps - cw - V1 +2      steps cw - V1 +208  steps - cw - V2 -2      steps ccw - VR1 -30     steps ccw - VR1 -208    steps ccw - VR2 242   steps net movement. 238     steps net movement. ______________________________________

FIG. 5 illustrates accelerated timesetting in the forward direction at a speed V3 which continues until the pushbutton is released, at which time speed reverts to slow speed V1 (Program 7).

Referring to FIG. 6 of the drawings, the multiple time correcting programs or modes are shown by means of a "state" diagram". The speed states are indicated by the blocks labeled V0, V1, V2, V3 in the clockwise direction, VR1, VR2 in the counterclockwise direction, and S for "stop". Initiation of transition of one state to the next, and the direction of state change, are indicated by symbols between the blocks. P designates momentarily actuation of the pushbutton 9 one time, 2P two times. Where the pushbutton is depressed and held for more than a preselected time period or depressed and released within less than a preselected time period, this is indicated in parentheses by (t>--), (t<--), respectively. Automatic transition from one state to the next is indicated by "AUTO". AUTO designates state changes after a predetermined number of pulses determined by counters K, L, M.

The diagram should be self explanatory when considered in connection with the following Table 3. __________________________________________________________________________ INITIATION PROGRAM PROG.

For example, program 1 for a single time zone change forward is initiated by a single momentary pushbutton pulse P. The timesetting proceeds at a slow speed V1, then automatically to a fast speed V2, and then automatically restarts normal V0 speed and resets all counters without affecting timekeeping of the watch. Program 5 initiated by two momentary pushes of the pushbutton to cause the minute hand to move (after two steps forward) at slow speed VR1 in the counterclockwise direction. A single momentary push P of the pushbutton during VR1 stops the watch. Another push P restarts the watch and resets the counter 60. This mode of correction is conveniently used when adjusting the time using a time setting standard or reference signal. Other programs can be understood by using Table 3 in conjunction with FIG. 6.

Thus, there has been decribed an improved time correcting electronic circuit useful for a quartz analog stepping motor watch. While there has been described what is considered to be the preferred embodiment of the invention, other modifications will occur to those skilled in the art. It is desired to secure in the appended claims all such modifications as fall within the true spirit and scope of the invention.
