Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a watch used for medication, etc.

[Prior Art] Conventionally, for example, as a clock for patients who take medicine at regular intervals, a clock with an alarm function is attached to the lid of a medicine container, and the time is displayed by closing the lid after taking the medicine. A method has been proposed (US Pat. No. 4,419,016) that locks the clock to the current time. According to this, since the time when the last time the medicine was taken is displayed, the time when the next medicine is to be taken can be easily calculated, which is useful for preventing forgetting to take the medicine.

It also has a function of notifying the time of taking the medicine with an alarm sound by setting the time of taking the medicine as the alarm time.

[Problem that the invention aims to solve] In the above case, when the lid is closed,
The disadvantage is that the current time cannot be known.

In order to know the current time, you have to open the lid, and once you open the lid, the time of the previous dose is erased, and if you close the lid again after checking the current time, the time will be locked. It was hot.

Also, since it has an alarm function, it requires a mode switch for current time display mode, alarm time display mode, etc., a time correction switch, an alarm set switch, etc., and this type of device has space constraints. , the number of switches increased, which was undesirable.

The object of the present invention is to provide a clock that allows the user to easily check the current time without erasing the fixed time, and that requires fewer switches.

[Means for solving the problem] The present invention fixes the time display on the display section to the time when the lap time switch starts operating while the lap time switch is in operation. This device is characterized in that it is provided with a display changeover switch that changes the display section to display the current time using a timekeeping circuit, and that this display changeover switch is also used as an alarm setting switch.

[Embodiment] In FIG. 1, 1 is a crystal oscillator, 2 is a frequency dividing circuit, and 3 is a clock circuit for measuring time, morning and afternoon, and day of the week. 4 is an alarm circuit for setting an alarm time, 5 is a comparison circuit for comparing the current time and the alarm time, and 6 is a sounding device such as a buzzer. 7
2 is a display section showing the current time, alarm time, etc. 8 is a mode switch, and mode switching circuit 9
Current time display mode (LOCK) by supplying output to
Time set mode (TIME), day of the week set mode (DAY), and alarm time display mode (ALM)
This is to select. 10 and 11 are up and down correction switches, respectively, and 12 is a lap time switch, which in this example is operated by a protrusion 12a provided at the lower end of the watch body as shown in FIG. In this example, the watch body shown in FIGS. 2 and 3 is attached to the lid of a medicine container (not shown), and when the lid is tightened, the protrusion 12a is pressed and the switch 12 is closed. It is configured. Reference numeral 13 denotes a display changeover switch for switching the fixed time display to the current time display. 14 is a latch circuit, and switch 12
This latches the output of the clock circuit when the gate is closed. Reference numeral 15 denotes a selection circuit for selecting the display content on the display section 7. 16 is a one-shot pulse generation circuit, 17 is a flip-flop circuit, 1
8 to 24 are gate circuits, and 25 is an inverter. Gate circuits 18 and 19 constitute a switching circuit, and gate circuit 20 and latch circuit 14 constitute a control circuit.

Next, the operation will be explained. First, the state in which the lid to which the watch body is attached is open, that is, the state in which the switch 12 is open, will be described. In this state, each time switch 8 is closed,
Modes are selected in the order of LOCK→TIME→DAY→ALM→LOCK (Mode B).

In the LOCK mode, the output of the mode switching circuit 9 selects the terminal _S1 of the selection circuit 15, and the output of the latch circuit 14 is supplied to the display section 7 and displayed. Since the switch 12 is now open, the latch circuit 14 allows the output of the clock circuit 3 to pass through as it is, and the display section 7 displays the day of the week, morning and afternoon, and the current time.

In the TIME mode, terminal _S2 of the selection circuit 15 is selected, the output of the clock circuit 3 is selected, and the display section 7
is supplied to On the other hand, the output from the mode switching circuit 9 causes the clock circuit 3 to enter the time set mode (TSET), and by operating the switch 10 or 11 in this state, the current time is corrected.

In the DAY mode, the output of the clock circuit 3 is displayed in the same manner as above, and the clock circuit 3 is in the day of the week set mode (DSET). In this state, the switches 10 and
The day of the week is corrected by 11.

In the ALM mode, the terminal _S3 of the selection circuit 15 is selected and the output of the alarm circuit 4 is displayed on the display section 7. At the same time, the alarm circuit 4 enters the set mode, and the switches 10 and 11 enable setting of the alarm time. When the desired alarm time is set by the switches 10 and 11, by closing the switch 13, the output of the gate circuit 21 becomes "1", the flip-flop circuit 17 is triggered, and the 1 input of the gate circuit 24 is activated. is held at "1" and an alarm is set. In other words, the display changeover switch 13 also serves as an alarm set switch.

In addition, if you want to cancel the alarm setting,
In the ALM mode, flip-flop circuit 17 is activated by operating switch 13 again.
enters the reset state, and the reset is performed.

As described above, when the switch 12 is open, it functions as an alarm clock.

Next, close the lid with the watch body attached and turn switch 1.
The operation in the state where 2 is closed will be explained. When the switch 12 is closed, the mode switching circuit 9 is reset by a pulse from the one-shot pulse generating circuit 16, and is fixed to the LOCK mode. The output of the clock circuit 3 at this time is loaded into the latch circuit 14 by the output of the switch 12 at this time, and is latched. Therefore, the display on the display section 7 is fixed to the clock display when the switch 12 is closed. In other words, the time of the previous medication will be fixedly displayed on the display section 7.

In this state, if it is desired to know the current time, the switch 13 is closed, whereby the output of the gate circuit 18 becomes "1" and the terminal _S2 of the selection circuit 15 is selected. Therefore, while the switch 13 is closed, the output of the clock circuit 3 is supplied to the display section 7, and the current time is displayed. When the switch 13 is opened, the display switches to the output of the latch circuit 14 again.

Even in a state where the display is fixed in this way, it is possible to easily switch to the current time display, and furthermore, the previous medication time will not be erased by this switch.

By the way, in the above state, the switch 12
The mode switching circuit 9 is in the mode A state by the output of
mode and ALM mode can be switched so that they are selected alternately. Therefore, the alarm time can also be confirmed by operating the switch 8.

Next, the alarm sounding operation will be explained.
The current time of the clock circuit 3 and the alarm time of the alarm circuit are compared by the comparison circuit 5, and when the two match, the output of the gate circuit 24 becomes "1".
The sounding device 6 is driven to generate an alarm sound.
In this state, by operating any of the switches 10, 11, and 13, the flip-flop circuit 17 is reset and the alarm sound stops.

In the above embodiment, when the display is fixed at the time of the previous administration, the display switches to the current time display only while the switch 13 is closed, but the present invention is not limited to this. Occasionally, the timer circuit generates an output for a certain period of time,
While this output is being generated, the display may be switched to the current time display.

Further, in the above example, a case has been described in which only one type of alarm time is set, but a plurality of types may be set, and an alarm sound may be generated at each of the alarm times.

[Effects of the invention] According to the invention, while the lap time switch is operating, the display is fixed at the start time of the lap time switch, and the display is switched to the current time display by operating the display changeover switch. As a result, the current time can be easily checked at any time, and the start time of the lap time switch can be fixed at that time again without being erased.

Furthermore, the display changeover switch also functions as an alarm setting switch, and the alarm is set by operating the display changeover switch after setting the alarm time, so the number of switches can be reduced, resulting in smaller space and lower costs. can do.
