Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an analog multifunction watch that has a plurality of time or time measurement functions and displays the outputs of the functions on the same display device, and particularly relates to a timer function display thereof. Regarding the method.

[Prior art]

Conventionally, most analog watches have a single function of timekeeping, but there are a small number of analog watches that have an alarm function and a stopwatch function. These responded to the desire to make a multifunctional watch while retaining the beauty of an analog watch, but since each function required a separate display device to display the functional output, making it multifunctional The display area becomes cluttered and each display becomes smaller, making it difficult to see.Therefore, an analog multi-function watch that displays the output of each function in a time-divided manner on the same display device like a digital watch can be considered, but a digital watch Since it is not possible to easily add an indicator like on the display device, it is difficult to determine which function's output is currently being displayed, and especially in the case of a timer function, it is impossible to know at all what the current state of the timer is. A problem arises.

〔the purpose〕

The purpose of the present invention is to solve the above-mentioned problems, and to make it possible to easily know what the current timer status is when the timer function is displayed. Our goal is to provide functional watches.

〔overview〕

An analog multifunction watch that has multiple time or time measurement functions including a timer function of the present invention and displays the outputs of the measurement functions on the same display device is one of the output display devices of the measurement functions when the timer function is displayed. The at least one display member is configured to serve as an operating state indicator indicating the operating state of the timer function, and the at least one display member serving as the operating state indicator starts to move and returns to its original state. The number of steps required to return to the position is A
1. When the one step period is 4 seconds, /B has A and B which are divisors of 60, and the timer setting is in minutes.

[True story example]

The present invention will be described in detail below based on the drawings.

FIG. 1 is an external view of the embodiment, and is a well-known time display section 10.
6 and the calendar display section 109, a sub-hour hand 108 and a sub-minute hand 107, each of which is moved by an independent driving mechanism, are newly provided.

The sub-hour hand 108 and the sub-minute hand 107 are the home time.

It can display the alarm ringing time, remaining time of the timer, and dual time.To switch the display of each function, press buttons 101 to 1103 (S■ to ■) and crown 1.
The operation Q of 104 (S■ and @) is performed in response to each mode signal formed thereby. Further, the sub-hour hand 108 serves as an operating state indicator that particularly indicates the operating state when the timer function is displayed.

The crown 104 has stable positions of I, II, and m, and performs a switch function (SW■ is ON when the river is on, SW■ is ON when it is Ill), as well as a well-known analog electronic watch with a calendar. It is connected to the correction mechanism of the calendar display section 109 at the position (2), and to the second and hour/minute adjustment mechanisms of the time display section 106 at the position (2). Further, the crown 104 is also used to correct the display of the alarm mark 105, and each time the crown 104 is pushed in from the I position, it alternates between a ringing state and a non-ringing state.

Sw ■ is linked to the alarm mark 105, and Sw
[F] is turned ON when the alarm mark 105 is showing a ringing sound.

FIG. 2 is a block diagram showing the system of the embodiment. The system of this embodiment includes an 0MO3-LSI 201, a silver oxide battery for wristwatches 202, an ultra-small crystal oscillator 203, a buzzer drive transistor 204, a piezoelectric buzzer 205, a boost coil 206, step motors 207 to 209, and a gear train 21.

battery 202, vibrator 205, step motor 207, gear train 210, regulation/correction mechanism 216, time display section 106,
The calendar display section 109 is well known from conventional analog electronic watches with a calendar, so a description thereof will be omitted. Furthermore, the buzzer driving transistor 204, the piezoelectric buzzer 205, and the boost coil 206 are also well known in the electronic timer with alarm, so their explanation will be omitted.

The step motor 208, the wheel train 211, and the sub-minute hand 107 are for displaying the minute digit as an additional function.
is constructed so that the sub minute hand 107 makes one revolution in 60 steps. Further, the step motor 209, the wheel train 212, and the sub-hour hand 10B are used to display the hour digit as an additional function, and the wheel train 212 is configured so that the sub-hour hand 108 makes one revolution in 24 steps. In this way, the sub-minute hand 107 and the sub-hour hand 10 are moved by independent mechanisms, so that when the mode is switched, they can reach the desired position in a short time.

FIG. 3 is an operation state transition diagram of the embodiment. In the figure ■, ■,
■ are the button buttons 101, 102, and 1 in Figure 1, respectively.
This shows that 05 has been pressed. Also, ■■ indicates that the pushbuttons 101 and 102 were pushed simultaneously. Note that the method for correcting the calendar display section 109 and the time display section 106 is well known, and therefore will not be described here.

When the button 104 is in the I position, each function is called up, and the button 101 directly activates the alarm function, the button 102 directly activates the timer function, and the button 105 directly activates the dual time function. called and displayed.

In this state, when the Yuzu 104 is pulled out from I to ■, the time of each function is set. The hour digits for each function are set by the button 101, and the minute digits are set by the button 102. However, in this embodiment, the timer is a 60-minute timer, and the setting of the hour digits is invalid.

When the crown 104 is moved to the ■ position, the home time setting state is entered. Here, home time is basically a function to provide the internal circuit with the current time indicated by the time display section 106, and is counted up in synchronization with the current time, and has an important meaning especially for the alarm function. have In other words, the alarm sounds when the home time and alarm time match.

Even in the home time setting state, the button 101 sets the hour digits, and the button 102 sets the minute digits.

When the button 106 is pressed for 1 to 2 seconds in the home time setting state, the circuit is initialized. Initialization here means to match the display position of the sub-hour hand 10B and the division hand 107 with the circuit content. In this embodiment, when the memory of the circuit is erased due to battery replacement, etc., the button 104 is moved to the positive position. After setting the sub-hour hand 108 and division hand 107 to the zero position using buttons 101 and 102 and initializing using button 103 to match the circuit contents and the display position of the hands, the home time is set. .

From the home time setting state, push the crown 104 to [1L].
125 to 1188 seconds, the home time display state is entered instead of the alarm time display state, and it is possible to check whether the home time has been properly set.

If it is desired to check the home time when other functions are displayed, it can be called up by pressing buttons 101 and 102 at the same time.

In the embodiment, the number of steps that the sub-hour hand 10B) rotates is A1.
When the period of one step is /B seconds, A/B is 60 (1
This can be easily achieved by setting A and B to be divisors of the number of seconds in a minute.

〔effect〕

As described above, according to the present invention, it is possible to know at a glance that the timer function is displayed and its operating state with a simple configuration. Furthermore, when the remaining time reaches 0, the operating status pointer returns to the 0 position, giving the user an impression of the accuracy of the clock.

In addition to being able to provide mechanical beauty,
Since the pointer automatically returns to zero, there are also benefits in terms of use, such as eliminating the need for a reset operation.
