Description

  The present invention relates to an analog timepiece device, and more particularly to an analog timepiece device that displays a time using a pointer.

Conventionally, analog timekeeping devices mounted on automobiles have been limited to time display because the time is displayed by hands and dials. In addition, an analog timing device that displays a calendar using a pointer as a display function other than the time has been proposed (see, for example, Patent Document 1).
JP 2000-147157 A

  However, conventional analog timekeeping devices for in-vehicle use only display time, and there is no display using the dial of the analog timekeeping device for information obtained by other functions such as direction, altitude, and weather. .

  The present invention has been made in view of the above points, and an object thereof is to provide an analog timing device capable of displaying information obtained by functions other than time.

  FIG. 3 shows a process flowchart of the microcomputer 112.

  The microcomputer 112 displays the time in step S1-1. When the function selector switch SWs is turned on in step S1-2, the microcomputer 112 turns on the light emitting diodes LED0, LEDn, LEDe, LEDs, and LEDw in step S1-3, and acquires a direction detection signal from the detection unit 113. Based on the acquired azimuth detection signal, for example, the azimuth in the direction indicated by the time “12” of the indicating device 111 is detected, and the direction indicated by the time “12 o'clock” of the indicating device 111 is defined as the N direction. The hour hand drive motor 132 and the minute hand drive motor 134 are controlled so that both of the minute hands 130 point to the detected direction. At this time, the microcomputer 112 continues to count the current time.

  When the function selector switch SWs is turned off in step S1-4, the microcomputer 112 returns to step S1-1 to display the time. At this time, the microcomputer 112 displays the time that has been continuously counted even during the azimuth display.

  FIG. 4 shows an operation explanatory diagram of one embodiment of the present invention. 4A shows the time display state, and FIG. 4B shows the direction display state.

  In the time display state, the function selection switch SWs is off, the light emitting diode LED0 is off as shown in FIG. 4A, and the indicator provided on the dial 127 is off. Thereby, it can be recognized that the hour hand 129 and the minute hand 130 indicate the time.

  When the function selection switch SWs is turned on, the azimuth display state is set. In the azimuth display state, as shown in FIG. 4B, the light emitting diodes LED0, LEDn, LEDe, LEDs, and LEDw are turned on, the indicator indicating the azimuth indication state is lit on the dial 127, and “N” indicating the azimuth is displayed. ”,“ E ”,“ S ”,“ W ”are lit. Thereby, it can be recognized that the hour hand 129 and the minute hand 130 indicate the direction. In the present embodiment, the azimuth indicating state is indicated by the indicator 122 including the light emitting diode LED0, but at the time of azimuth indicating, the light emitting diodes LEDn, LEDe, LEDs, and LEDw are lit, and the characters indicating the azimuth are lit. Since it is easy to recognize that the direction is instructed, the indicator 122 may be deleted.

  According to this embodiment, when the light emitting diode LED0 is turned off, the hour hand 129 and the minute hand 130 indicate the time, and when the light emitting diode LED0 is turned on, the hour hand 129 and the minute hand 130 indicate the direction. You can see that As described above, according to the present embodiment, it is possible to display other functions such as the direction with the hands of the timepiece.

  The light emitting diode LED0 may be directly attached to the dial 127 or attached to the printed wiring board 126 by a lead wire or the like.

  In this embodiment, when the direction is indicated, the indication direction is clarified by overlapping the hour hand 129 and the minute hand 130, but the hour hand 129 and the minute hand 130 are oriented in a direction of 180 degrees as shown in FIG. It may be arranged linearly to indicate the azimuth direction. At this time, for example, the direction indicated by the minute hand 130 is set as the direction indicating direction.

  In the present embodiment, the example in which the time and direction are displayed using the same pointer has been described, but the altitude and the weather can also be displayed using the same pointer.

  FIG. 6 is a block diagram of the second embodiment of the present invention, and FIG. 7 is a diagram for explaining the operation of the second embodiment of the present invention. In the figure, the same components as in FIG.

  The timing device 200 according to the present embodiment includes a pointing device 211, a microcomputer 212, an atmospheric pressure sensor 213, an altitude display switch SWs1, and a weather display switch SWs2.

  The indicating device 211 includes light emitting diodes LEDs1, LEDs2, and a resistor R, and the display pattern of the dial 221 is different from that of the indicating device 111.

  The microcomputer 212 detects the atmospheric pressure detected by the atmospheric pressure sensor 213, takes a log of the detected atmospheric pressure, and determines the weather based on the detected change in the atmospheric pressure. When the change in the atmospheric pressure is gradually reduced, it is determined that the low atmospheric pressure is approaching and the weather is downhill, and control is performed to instruct “cloudy” or “rainy”.

  Further, the microcomputer 212 measures the altitude according to the detected atmospheric pressure. At this time, since the reference atmospheric pressure changes due to the change in atmospheric pressure, the altitude is determined in consideration of the change in atmospheric pressure and the like.

  When the altitude display switch SWs1 is turned on, the time measuring device 200 of the present embodiment emits the light emitting diodes LEDs1 and indicates that the minute hand 130 indicates the altitude by pointing the direction of the light emitting diodes LEDs1. In addition, the minute hand 130 moves to the altitude indicating position on the dial 221 to indicate the altitude. When the weather display switch SWs2 is turned on, the light emitting diode LEDs2 emits light, and the hour hand 129 indicates the direction of the light emitting diode LEDs2, thereby indicating that the minute hand 130 indicates the weather. It moves to the weather instruction position on the board 221 and instructs the weather.

  As with the directions “N”, “E”, “S”, and “W” in FIG. 1, when the altitude display switch SWs1 is turned on, the altitude display is lit and the altitude display switch SWs1 is off. When the weather display switch SWs2 is turned on, the weather display is turned on. When the weather display switch SWs2 is turned off, the weather display is turned off. May be.

  In this embodiment, altitude display and weather display are performed separately. However, when the altitude display switch SWs1 and the weather display switch SWs2 are simultaneously turned on, the altitude is indicated by the minute hand 130 and the weather is displayed by the hour hand 129. You may make it indicate. Thereby, a plurality of information can be instructed simultaneously.
