ELECTRONIC TIMEPIECE WITH A MULTI-TIMER
Abstract
An electronic timepiece constructed as a wristwatch with a
multiplicity of timer devices for setting therein different time
settings either by actuation of setting switches or by reading in
the time settings from a program in the form of a punched tape. The
settings are introduced into the watch's electronic circuit without
affecting its outputs indicating elapsed time. The time settings
are stored and the wearer of the watch is warned by a bell or a
light, visually or audibly when the actual time corresponds with
the time setting memorized in registers forming the memories of the
electronic circuit. The time set and the elapsed or actual time can
be displayed on a display panel of the timepiece.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to electronic timepieces with
multi-timers and more particularly to an electronic timepiece
provided with a plurality of timers therein by which a plurality of
times can be set and be visually or acoustically indicated to a
user.
Conventional timepieces have had their timer mechanisms separated
from the movement of the timepiece themselves so that they have
been unsuitable for use as portable timepieces such as wrist
watches. Further the mechanical operation of a plurality of timers
have required complicated cam-mechanisms in order that they may be
operated at a set time. Furthermore, the time-setting in the
conventional timers have been restricted to the order of minutes
with attendant accuracy.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a portable
electronic timepiece provided with a plurality of timers therein
each operated at a predetermined set time optically or
acoustically.
Another object of the present invention is to provide an electronic
timepiece provided with a plurality of timers to which a desired
time can be set by suitable means.
Still another object of the present invention is to provide an
electronic timepiece provided with a plurality of timers and which
has a display section on which the usual elapsed time as well as
the time to be set in the timers can be displayed alternatively by
means of a switching operation.
An electronic timepiece provided with a multi-timer according to
the present invention comprises a standard oscillator for producing
a signal of high frequency. A divider divides the high frequency
signal to a low frequency signal serving as a standard time signal.
Counter means count the time signal frequencies. Means for
displaying the time signal, obtained by the counter means, display
at a display panel in digital form, and at least one memory circuit
stores the time signal. Setting means are provided as a counter
means connected to the memory circuit and driven by a pulse signal
having a predetermined frequency until a desired time signal is set
on the memory circuit. The setting means may be a read-out device
for reading out an input including a time signal to be set at the
memory circuit. Further, the setting means may be means for
registering a time signal in seconds produced by the counter means
to the memory circuit. An electronic timepiece with a multi-timer
according to the present invention further comprises means for
switching a usual time and a time set to the multi-timer. Thus, the
usual time and time set at the multi-timer can be interchangeably
displayed on the display panel in response to the operation of
switching means.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, particularly to FIG. 1, an electronic
timepiece according to the present invention comprises a display
panel 1 on which time is digitally displayed. An electronic circuit
for controlling and driving the display panel, and a plurality of
switches for operating the electronic circuit are later described.
The display panel 1 has on its face a unit-second display element
3, 10-seconds display element 4, unit-minute display element 5,
10-minutes display element 7 and 10-hours display element 8, and
has marks S, M and H arranged above and to the right thereof for
clearly distinguishing seconds, minutes and hour displays from each
other. Usually, the elements 3 to 8 are comprised of seven segments
each made of a liquid crystal or light emission diode. On the
display panel 1 there are arranged a time display element 9 by
which the fact that the electronic circuit is operated to display
usual time is indicated, timer display elements 11 to 13 by which
the operations of a multitimer of the timepiece are indicated, and
an alarm display element 10 by which the operation of an alarm
circuit for alarming at a predetermined time is indicated. These
time and alarm display elements 9, 10, 11 to 13 are constructed as
light emission diodes or liquid crystal panels.
On the other hand, in the circuit there are a plurality of normally
open switches, i.e., a switch 14 for setting timers, a switch 15
for changing over the timer display and usual display, a switch 16
for setting the hour time signal, a switch 17 for setting the
minutes time signal and a switch 18 for resetting the seconds time
signal. The function of each switch will be fully described later
in connection with the description of the operation of the
electronic circuit. The pushbuttons for these switches are
illustrated mounted on the display panel 1 and bear the
corresponding reference number as the corresponding switches later
described.
In operation, a standard signal of high frequency is derived from
an oscillator 19 and is counted down or divided to a one-second
signal (a signal having a frequency of one pulse per second) by a
divider 20 and is counted by a counter 21 for counting the seconds
time signal. The counter 21 is constituted as an 60-abic counter
producing output signals on a line 21a, which are applied to the
seconds display elements 3 and 4 through a decoder 24 and a driver
27 to display the time 0 to 60 seconds. On the other hand, on the
line 21b of the counter 21 there is applied a 1-minute signal,
which is counted by a 60-abic minute counter 22 to drive the minute
display elements through a line 22a, a decoder 25 and a driver 28
in order to display the time 0 to 60 minutes. Similarly, a 1-hour
signal applied on the line 22b of the counter 22 is counted by a 24
abic counter 23 to display the time 0 to 24 hours, operating the
hours display elements 7 and 8 through line 23a, a decoder 26 and a
driver 29.
Thus, the electronic timepiece according to the present invention
effects the time display on its display panel 1 with accurate
time-keeping when no switches 2 are operated. A gate circuit 30 is
operated due to the application of a "1" voltage (having a
predetermined voltage value) and a "1" voltage on the line 32a of a
NOT circuit 31 to drive the display element 9 with the voltage "1"
in order to display the usual elapsing time.
The closing of the timer switch 15 causes the voltage "1" on the
line 31a to be inverted to a voltage "0" by the NOT circuit 31 to
stop the functions of the decoders 24 to 26 through the gate
circuits and further the functions of the AND gate 30, thus
extinguishing the time display on the display panel with the time
display element 9 turned off, although the time is properly counted
by the counters 21 to 23. In this state, the operation of the
minute setting switch 17 causes the voltage "1" and the setting
pulse signal (usually having a frequency of more than 1Hz)
transmitted through the line 34 to be applied to a gate 32 to
produce the setting pulse on a line 32a. This signal is applied to
the 60-abic counter 35, the output signal of which is then applied
to the driver 28 through the gate and the decoder 25 to effect the
setting of the minute by driving the minute display elements 5 and
6 quickly. On the other hand, the operation of the hour setting
switch 16, similarly to that of the minute setting switch, causes
the setting pulse to appear on the line 33a of the gate circuit 33.
The setting pulse operates a 12-abic counter 36 and is applied to
the decoder 26 through the line 36a of the counter and the
gate.
Thus, the hour setting pulse drives hours display elements 7 and 8
through the driver 29 to effect the setting of hours.
Alternatively, the setting of the hours may be effected by applying
to the 12-abic counter 36 a pulse signal produced on the line 35b
of the 60-abic counter 35 to display the set time on the display
panel. It is to be noted that the setting of the hours or minutes
is effected in order to set the time of the timers so that a group
of counters 21 to 23 continue to count the signals produced from
the preceding stage independently of the time setting operation.
Further, the setting of seconds is also effected using a circuit
configuration similar to that used for the setting of the hours or
minutes, but it is not described in the embodiment.
The time signals for the timer, after being set, are stored in
registers. The actuation to "on" of the timer setting button 14
causes a signal to be produced on a line 37a of a shift register
37. The signal is applied to gate circuits 38 to 40 having their
output terminals connected to registers 41 to 43, respectively. The
gate circuit 38 receives the set hours time signal from the counter
36 through the line 36a; the gate circuit 39 receives the set
minutes time signal from the counter 35 through the line 35a; and
the gate circuit 40 receives the seconds time signal from the
counter 21 through the line 21a, 21b. The generation of the signal
on the line 37a due to the operation of the switch 14 allows the
set signals for hours and minutes and the running second signal to
be successively read into the registers 41 to 43 for storing.
Further, the signal on the line 37a turns on the timer display
element 11 through the 37b to indicate the registration of the time
signal on the registers 41 to 43. Such a registration of the time
signal is multiplied or effected by providing other registers.
Registers 44 to 46 are connected in a configuration similar to the
register 41 to 43 so that the signals from the counter 36, 35 and
21 can be applied thereto through gates 50 to 52. The minute and
hour setting switches 17 and 16 are operated to store the set time
in the registers until the desired time is displayed on the display
panel 1 in the same way as mentioned previously. Then, the
operation of the timer setting switch 14 causes the shift register
37 to produce signals on the line 37b to operate the gate circuits
50 to 52 and store the signals in the registers 44 to 46. This
state is confirmed by the turning-on of the timer display element
12 connected to the line 37e. Further, registers 47 to 49 are
connected in the same configuration as the registers 41 to 46 to
memorize the desired time therein with the indication of this state
on the time display element 13. It will be appreciated that the
desired time signals can be stored in multiple by increasing the
number of the memory circuits although only three memory circuits
are illustrated in the embodiment.
Irrespective of a series of operations, the counters 21 to 23
continue to count the timer signal, so that the gate circuit 53 is
operated to produce the signal on the line 53a when the signal of
the hour counted by the counter 23 coincides with that of the hour
stored in the initially set register 41; the gate circuit 54 is
operated to produce the signal on the line 54a when the signal of
the minute counted by the counter 22 coincides with that of the
minute stored in the register 42; and the gate circuit 55 is
operated to produce the signal on the line 55a when the signal of
the second of the counter 21 coincides with that of the second in
the register 43.
Thus, when the time elapsed time corresponds to one of the set
times, the gate 56 is operated to drive a time-signal retaining
circuit, for example a one-shot multi-vibrator, for retaining a
time signal during a predetermined period, during which an alarm
device 58, which may be a bell or a lamp, is operated to inform a
user of the arrival of the set time, indicating this state with the
display element 10 turned on through the line 57a. Further, when
the time elapses at the time stored in the registers 44 to 46 or 47
to 49, the gate 56 operates to drive the alarming circuit.
Thereafter, the alarm circuit is operated to inform of the time
every time of the arrival of each set time. The alternation of the
time signal stored in the register, if desired, can be affected by
operating the setting switches 16 and 17, and the switch 14 in the
same way as mentioned above. Further it will be appreciated that
the write-in or read-out of the time signal may be carried out in
series in succession. The switch 18 serves to reset the second
counter and the operation thereof allows the counter 21 to be reset
with the zero indication in second display.
FIG. 2 shows an embodiment of an electronic timepiece with a
multi-timer wherein the desired set time is stored directly into
the register, and the particular electronic circuits are shown in
FIG. 3. The electronic timepiece 60 is provided with a wrist band
61. On the marginal portion of the upper surface of the timepiece
60 is mounted a detecting device 62 comprising a head portion from
which light emanates, guide means 66 and 67 for introducing a
punched tape 63 wherein the time signals are stored as
perforations, and a detector 65 including electronic circuits for
converting the time signals to the electronic signals. The punched
tape 63 has sets of four perforations 63a to 63d arranged thereon
in a direction perpendicular to that along which the tape advances
as shown in FIG. 2. The punched holes 63a to 63d, for example,
represent the time switching signal, the signals for hour, minute
and second settings, respectively, forming binary coded signals of
the time signals to be registered in succession. It is to be noted
that the time signals may be registered using commercially
available cards for computers instead of the punched tape.
The write-in or read-out circuit as shown in FIG. 3 is
substantially similar to that shown in FIG. 1 except for input
sections. The circuit shown in FIG. 3 requires no switches such as
the ones 14 to 16 in FIG. 1. Photoelectric elements 70a to 70d,
such as phototransistors, receive light beams emanating from light
sources (not shown) provided in the detector head in FIG. 2
corresponding to the photoelectric elements 70a to 70d, and produce
the signal according to the holes punched in the tape. The
photoelectric elements 70a to 71d are, respectively, connected to
wave shaping circuits 71a to 71d to convert the produced on the
photoelectric elements 70a to 70d to the pulse signals. The outputs
of the wave shaping circuits 71a to 71d are, respectively,
connected to the gate circuits 72a to 72d to which signals are
applied by means of the switch 15. In the same Figure, the
photoelectric element 70a corresponding to the punched hole 63a of
the card as shown in FIG. 2 receives the information therefrom to
select the predetermined register in order to set the time. The
signal from the photoelectric element 70a is applied to the shift
register 37 through the line 37a. The photoelectric elements 70b to
70d correspond to the punched holes 63b to 63d, respectively,
receiving the time signals for hours, minutes and seconds. These
time signals are stored at the registers 41 to 49 through the lines
73b to 73d. Thus, the time information of the punched tape, for
example, are punched in a binary code in succession along the
travelling direction of the tape. The shift register 37 is operated
by punching the hole 63a to actuate the photoelectric element 70a
in order to set the time to the first timer. The shift register 37
produces the signals on the line 37a to apply them to AND gates 38
to 40 respectively connected to the registers 41 to 43. In turn or
at the same time, the photoelectric elements 70b to 70d receive the
time signals of hour, minute and second to store the hour signal in
the register 41, the minute signal in the register 42, and the
second signal in the register 43, respectively. It is to be noted
that the signal always appears on the line 37a because the
photoelectric element 70a does not receive the signal from the
punched tape during storing.
After the first time-setting has been finished, then leftwardmost
column in the tape is punched in such a manner as to operate the
photoelectric element 70a. The signal developed on the element 70a
operates the shift register 37 to allow the signal to appear on the
line 37d. The signal is applied to AND gates 50 to 52 respectively
connected to the register 44 to 46. In turn, or at the same time,
the photoelectric elements 70b to 70d receive the time signals from
the punched tape to store them in the registers 44 to 46, thus
finishing the second time-setting. Similarly, the third time can be
set in the registers 47 to 49. It is to be noted, in this case,
that it is obvious that the set time can be visually displayed by
means of a simple read-out circuit although not shown in the
embodiment because the circuit for displaying the set time at the
display panel 1 is omitted for the purpose of simplification. The
alarm device is operated in the same way as mentioned in connection
with the embodiment in FIG. 1.
FIG. 4 shows another embodiment of the electronic circuit by which
the timer is set in a more simplified way. The circuit has a
configuration similar to those shown in FIGS. 1 and 2, and employs
the circuit for storing the time signal derived from the counter 21
counting the signal of second from the divider 20 instead of using
the time-setting circuit and input device as shown in FIGS. 1 and
2, respectively. The output lines of the counter 21 are,
respectively, connected to an AND gate 83 in turn connected to the
registers 41, 44 and 47 through the AND gate, and to an AND gate 82
connected to the registers 42, 45 and 48 through the AND gate.
Further minute and hour setting switches 80 and 81 are provided,
the actuation of which causes a signal "1" to be applied to the AND
gates 82 and 83 simultaneously with the function of decoders 25 and
26 turned out to extinguish the minute and hour displays,
respectively. When the first time is to be set at the timer, the
switch 14 is at first actuated to produce the signal on the line
37a. Then the actuation of the minute setting switch 80 causes the
signal to be applied to the AND gate 82 so that the time signal
displayed at the second display section upon the actuation of the
switch is applied to the gate 82 to store the signal at the
register 42 due to the actuation of the gate 39. On the other hand,
the actuation of the hour setting switch 81 causes the signal to be
applied to the AND gate 83 so that the time signal displayed at the
second display section upon the actuation of the switch 81 is
stored at the register 41 through the AND gates 83 and 38. These
time signals are applied to the decoders 25 and 26 through the
lines 82a and 83a to display them on the display panel.
Thus, the setting of the time X:Y, at the registers 42 and 41 is
carried out by operating the minute-setting switch 80 when the
digit Y appears on the seconds display element and by pressing the
hour-setting switch 81 when the digit X appears on the same.
Further, when the second or third time is desired to be set, the
switch 14 is operated to produce the signals on the lines 37b and
37c in the same manner as mentioned above in order to set the time
at the registers. It is to be noted that the output line 21b of the
seconds counter 21 is connected to the register 43, 46 and 49
through the gate except for the embodiment of FIG. 2, so that the
time-setting of the seconds encounters the difficulty that the
content of the register varies with the elapsing time, but the
unvariable time of seconds can be stored in the register by
providing suitable gate circuits or a secondssetting switch.
As mentioned above, the electronic timepiece with a multi-timer
according to the present invention includes therein a multi-timer
set to a plurality of predetermined times by a simple operation and
a device for acoutically or optically alarming the user at the set
times, so that a portable and compact electronic timepiece is
provided with the timer integrally combined with the timepiece
body. Moreover, a plurality of times are set by one time-setting
operation with the result that easy time setting operations can
take place at the same time. Furthermore, the electronic timepiece
provides multi-timer means of high accuracy because the time is set
in the order of seconds.
