Definitions

  • the present invention relates to a multifunctional watch comprising a first and a second motor, said first motor driving a display assembly comprising a second hand and the second motor driving a display assembly comprising a minute hand and an hour hand, electronic circuits delivering time base signals and control signals from said first and second motors and control members for selecting the functions of the watch, control means being provided allowing, in response to said signals and said control members , to control said display assembly driven by the first motor so that this display assembly of information other than the indication of normal time.
  • the stepping motor normally drives simultaneously all the display elements, i.e. the second, minute and hour hands. Consequently, the movements of these hands are linked by fixed gear ratios which do not allow the movement of one of the hands relative to that of the other hands to be dissociated, with the exception, however, of the movement of the seconds hand by compared to that of the minute and hour hands, during the time setting operation.
  • a multifunctional watch for example, it is particularly useful to have means of identifying the functions to be controlled, that is to say, to acknowledge the call to a function by an appropriate display.
  • FR-A-2 431 148 discloses an electronic timepiece comprising only a single stepping motor and in which the second hand can be controlled so as to indicate functions other than the second of the 'normal time. Due to the presence of a single motor, it is necessary to provide means for memorizing the information concerning the standard time and means for restoring this information after the execution of a function determined by the hand. seconds (split-seconds function). These means lead to an increase in the complexity of the electronic circuits and the energy consumption of the timepiece is high by the fact that each time the second hand performs a display function other than that of the second of standard time, it is necessary, at time intervals of one minute, to catch up with the exact time.
  • Also known from patent FR-A-2 394 840 is an electronic watch comprising two motors.
  • the first motor drives the minute and second hands and the second motor drives the hour hand.
  • the hour hand retains only a role of time indication and it is not assigned to the display of a particular function other than that of time indication.
  • Patent FR-A-2 442 433 describes a device which essentially aims to display in analog form by a needle on a dial, an external quantity applied in digital form to the input of the device. It is therefore a display device using a needle driven by a stepping motor, of measured parameters such as pressure, an operating parameter of a motor vehicle engine, a voltage , etc. However, the device is not designed for measuring time and it only allows a measured parameter to be displayed using at least one jumping hand.
  • the object of the present invention is to produce an electronic watch in which the second hand can be used to display information other than that of the seconds of the normal time.
  • the watch according to the invention therefore comprises means for controlling the first motor which, in response to the time base signals and to the control members, making it possible to control movements and displacements of the seconds hand so that the information displayed by this hand represent either an indication of the second of the normal time in relation to the minute and hour hands, or following an external call, the indication of information different from the second of the normal time.
  • the circuit of FIG. 1 comprises an oscillator 1 delivering a reference frequency to the input to a frequency divider 2. This delivers on its output b a minute signal for the control circuit 3 of the motor 4 driving the minute m and hour h hands and on its output c a signal determining the duration of the motor pulses.
  • the divider 2 also delivers, by its output, a seconds signal and on its outputs, time base signals applied to a logic circuit 5 allowing the control of the seconds hand.
  • the time base signals are schematically delivered only by a single output e of the divider, but it is clear that in reality these time base signals are delivered by a certain number of outputs of the divider.
  • the logic circuit 5 contains inter alia a plurality of circuits reacting on the one hand to the time base signals and on the other hand to control signals delivered by control members capable of being actuated manually. These control members are for example contacts 81, S2, actuated by pushbuttons external to the electronic circuit of the watch or else a contact C actuated by the crown of the watch. It is also possible to provide circuit control means 5 internal to the electronic circuit. This is the case, for example, of a detector 6 of the battery voltage Ba delivering a signal to the circuit 5 when the battery, reaching the end of its life, its voltage drops below a reference value.
  • the logic circuit 5 delivers signals to the control circuit 7 of the motor 8 driving the second hand s independently of the other hands.
  • the circuit 7 controls the motor 8 in forward and reverse directions.
  • circuit 5 delivers, by its output k, to circuit 7, the seconds signal it receives from divider 2.
  • the logic circuit 5 delivers to circuit 7, in response to the time base signals and to the number of actuated control members and possibly the number of actions exerted on these members, a signal different from that of the second.
  • the passage to 60 of the second hand s is detected either by a mechanical contact Cs on the axis of this hand, or by a counter of the electronic circuit.
  • This detection produces the resetting to zero of a reversible counter 9 which receives on its clock input c the signal from the output k of the logic circuit 5.
  • the input U / D for controlling the counting direction of the counter 9 receives a signal delivered by output 1 of circuit 5.
  • the above shows that the content of the reversible counter 9 is always representative of the position of the second hand on the dial. This content, present at the outputs a of the counter 9, is applied on the one hand to the inputs j of the logic circuit 5 and to the inputs A of a comparator 10.
  • the outputs a of the counter 9 and the inputs j and A of circuit 5 and comparator 10 are shown diagrammatically only on a single terminal.
  • the input B of the comparator 10 is connected to the output of a second counter 11 receiving on its clock input c the second signal from the output d of the divider 2.
  • the comparator 10 delivers to the input e of the logic circuit 5 a signal for the equality of signals A and B. It also delivers on another output line, also connected to the input e of circuit 5, a signal determining the movement in front or back of the second hand. This signal determines a normal movement in the conventional direction of rotation of the second hand when the content of the second counter 11 is greater than that of the counter 9 and a backward movement otherwise.
  • a delay circuit 12, controlled by the control members S1, S2 or C, is connected to the input d of the circuit 5.
  • the first example relates to the detection of the end of life of the battery Ba.
  • the detector 6 sends a signal to the input h of the logic circuit 5.
  • the circuit 5 commands for example the stopping of the second hand on a well-determined position of the dial, for example position 30.
  • circuit 5 compares the content of counter 9 present on its inputs j with a first quantity of corresponding internal fixed reference and the equality signal obtained by this comparison permanently interrupts the signal on the output of this logic circuit 5, so that the second hand remains definitively locked on the position 30 of the dial. The user then knows that he must soon change the battery of his watch.
  • the user wishes to change the time zone, he activates, for example, the crown of the watch.
  • the actuation of the crown allows on the one hand the closing of a contact C and on the other hand the driving of the hour and minute hands.
  • the closing of contact C controls the delay circuit 12 and delivers a signal to the input c of the logic circuit 5.
  • the circuit 5 delivers frequency pulses at its output k repeat greater than 1 Hz to control rapid advance of the second hand to a fixed mark F (like time zone) on the dial.
  • the circuit 5 delivers on its output k firstly a fast advance signal (frequency greater than 1 Hz) from the hand of the seconds then, as soon as the hand is opposite position 59 of the dial and in response to equality between the signal on outputs j and a third fixed internal reference quantity corresponding to the value 59, for example pulses of 2 HZ producing a second hand movement twice as fast as normal.
  • a fast advance signal frequency greater than 1 Hz
  • the circuit 5 delivers on its output 1 a rectangular signal of a period of 2 seconds alternately controlling each second the advance in front and back of the motor 8 and the reversible counter 9 so that the seconds hand makes two jumps every second, during the first second in reverse from position 59 to position 60 and at position 1 on the dial and during the second second in reverse from position 1 to position 60 and at position 59 on the dial , etc.
  • a catch-up function like that described in the previous example is performed and the second hand resumes its normal function for indicating the seconds of real time.
  • Figure 2 shows a circuit for controlling the movement of the second hand described above, during correction of the seconds display.
  • the circuit of fig. 2 comprises a memory 13, for example of the ROM type but which can also be produced by logic gates.
  • the memory 13 has address entries S1, Z, d, e, Q1 and Qo and it delivers its content on the terminals q1 and qo.
  • the input S1 is connected to the control member S1

  • the Qo output of FF16 is connected to a second input of each from doors 18 and 19 and through an inverter to a second input from each of doors 17 and 20.
  • the third inputs from doors 18, 19 and 20 respectively receive signals of 1 Hz, 32 Hz and 2 Hz delivered by the divider of frequency 2.
  • the outputs of doors 18, 19 and 20 are connected to the inputs of an OR gate 23 whose output k is connected to the clock input of counter 9.
  • the output 1 of gate 17 is connected to the 'U / D input of counter 9.
