The control unit 600 periodically receives the standard time radio wave and corrects the time of the time measuring unit 610. That is, the analog meter device 1 in the time display mode is a so-called radio wave correction watch.

  The illustrated case 100 is circular and thin, and at its back, a locking portion 120 for locking to a hook on the wall side and a retractable leg 130 for leaning it are provided. Yes. Reference numeral 140 in the figure denotes a battery box for storing a battery that serves as the power source 10 of the analog meter device 1.

  Next, the movement 500 of this example will be described. As shown in FIGS. 5 to 9, the movement 500 of this example is configured by housing a first drive system 510 and a second drive system 520 in a thin case body 530. The control means 600 is a circuit board provided with a required circuit, and is mounted on the front surface of the case body 530, and the first sensor 210 and the second sensor 220 are mounted on the circuit board.

  That is, in the manufacture of the analog meter device 1, the first drive system 510 and the second drive system 520 are provided inside the case body 530 to create the movement 500, and the first sensor 210, the second sensor 220, and the movement 500 are formed. , And the control means 600 are assembled into one unit, which is arranged inside the housing 100. According to such a configuration, complication of assembling work can be avoided. Further, if such a unit is arranged inside the housing 100, the design and size of the housing 100 can be easily changed. That is, the degree of freedom in designing the analog meter device 1 is improved, and various product developments can be easily performed.

  In particular, providing the sensors 210 and 220 on the circuit board serving as the control means 600 has an advantage that it is easy to ensure the detection accuracy by the sensors 210 and 220. Generally, when a sensor is connected to a substrate via a lead wire, a measurement error occurs in sensor detection due to the electrical resistance, wiring capacitance, etc. of the lead wire. In this respect, according to this example, such a measurement error problem can be avoided. The number of parts is reduced and the detection accuracy is improved. Further, when designing the housing, it is not necessary to consider where the sensor is arranged, so that the design work is facilitated.

  The first drive system 510 includes a first stepping motor 511 capable of forward / reverse rotation, a first reduction mechanism 512 connected to the first stepping motor 511, and a first pointer pipe 513 connected to the first reduction mechanism 512. At the same time, the second drive system 520 includes a second stepping motor 521 capable of forward / reverse rotation, a second reduction mechanism 522 connected to the second stepping motor 521, and a second pointer connected to the second reduction mechanism 522. It consists of a pipe 523. Each speed reduction mechanism 512, 522 is a train wheel having a predetermined gear ratio set, and a gear portion that meshes with each speed reduction mechanism 512, 522 is provided at the base end portion of each pointer pipe 513, 523, respectively. ing.

  The first indicator pipe 513 and the second indicator pipe 523 are provided so that one of them is inserted into the other and protrudes outside the front surface of the case body 530. A hole 601 that penetrates through the first pointer pipe 513 and the second pointer pipe 523 is provided at a key portion of the circuit board that is the control means 600. The first pointer pipe 513 and the second pointer pipe 523 project the case body 530 inside the housing 100 and the center of the dial 400. The first pointer 310 and the second pointer 320 are provided to be supported by the first pointer pipe 513 and the second pointer pipe 523, respectively.

  In addition, the movement 500 of this example includes a position detection unit 540 that detects the positions of the first pointer pipe 513 and the second pointer pipe 523. The illustrated position detection unit 540 is an interrupter including a light emitting element 541 and a light receiving element 542. The light emitting element 541 and the light receiving element 542 are arranged so as to sandwich the first driving system 510 and the second driving system 520 therebetween. Specifically, one of the light emitting element 541 and the light receiving element 542 is provided on a circuit board serving as the control means 600, and the other of them is provided at an important point on the back side of the case body 530. A light transmitting portion 543 that transmits light from the light emitting element 541 is provided at the main points of the first driving system 510 and the second driving system 520 located between the light emitting element 541 and the light receiving element 542. An LED is used as the light emitting element 541 and a phototransistor is used as the light receiving element 542. At the time of position detection, the first drive system 510 and the second drive system 520 are driven while the light emitting element 541 is turned on. The positions of the pointer pipes 513 and 523 are specified from the detection pattern of the light receiving element 542 at that time. In addition to the photo interrupter, a photo reflector can be adopted as the position detecting means 540. Further, the position detecting means 540 of this example detects the positions of both the first pointer pipe 513 and the second pointer pipe 523 with a pair of light emitting element 541 and light receiving element 542. However, the position detecting means 540 can be configured by providing the light emitting element 541 and the light receiving element 542 for each of the drive systems 510 and 520, respectively.

  The position detection by the position detection means 540 is executed when a reset switch 710 provided on the back surface of the housing is pressed. Or you may comprise so that it may perform regularly (for example, once a day) by the control means 600 provided with the time measuring means. After detecting the positions of the first pointer pipe 513 and the second pointer pipe 523, the control unit 600 counts the number of steps of the first stepping motor 511 and the second stepping motor 521 to count the first pointer 310 and the second pointer 320. Each indicated position is recognized.

  In the case of this example, a monitor switch 720 is provided on the front surface or side surface of the housing 100. In this example, the control means 600 stores a maximum temperature, a minimum temperature, a maximum humidity, and a minimum humidity in a predetermined time zone (for example, a time zone from 24 hours before to the present time), and this monitor switch 720. When is pressed, the first pointer 310 and the second pointer 320 are displayed according to the indicated positions. That is, the past environment data is displayed.

  For example, when the monitor switch 720 is pressed once in the environmental data display mode or the time display mode, the first pointer 310 indicates the maximum temperature and the second pointer 320 indicates the maximum humidity. When the monitor switch 720 is pressed twice, the first pointer 310 Indicates the minimum temperature and the second indicator 320 indicates the minimum humidity. When the button is pressed three times or when the monitor switch 720 is not pressed for a certain time (for example, 30 seconds), the environmental data display mode or the time display mode is restored. A speaker 730 is provided inside the housing 100. When the monitor switch 720 is pressed, a desired announcement flows along with the melody. Or you may comprise so that the past environmental data may be displayed regularly.

  In this example, as a switching means for switching between the environmental data display mode and the time display mode, a slide type changeover switch 740 is provided on the side surface or the front surface of the housing 100. When the user operates the changeover switch 740, the environmental data display mode and the time display mode are switched. Note that a remote control switch or the like can be adopted as the switching means. This is convenient when the housing 100 is used by being hung on a wall in the room. It is also possible to arrange a sound sensor in the housing 100 so that the mode is switched in response to a predetermined sound.

  Further, the dial 400 is provided with mode display means 750 for displaying the mode state. The illustrated mode display means 750 includes a first light emitting unit 751 and a second light emitting unit 752. In the environmental data display mode, the first light emitting unit 751 is turned on and the second light emitting unit 752 is turned off. In the time display mode, the first light emitting unit 751 is turned off and the second light emitting unit 752 is turned on. Alternatively, the display of the mode by the plate can be changed by driving the plate by a driving means such as a solenoid. According to the mode display means 750, it is possible to avoid a situation in which a person viewing the analog meter device 1 confuses environmental data and time with respect to the display of the analog meter device 1.

  Furthermore, in this example, as shown in FIG. 10, when the remaining amount of power of the power source 10 is reduced, the first pointer 310 and the second pointer 320 are overlapped and stopped. When the voltage of the power source 10 falls below a predetermined value set in advance, the control means 600 drives the first pointer 310 and the second pointer 320 to a predetermined position before the power is completely cut off. Stop them in position. The first pointer 310 and the second pointer 320 are overlapped and stopped at a position indicating the blank portion 403. At that time, both the first light emitting unit 751 and the second light emitting unit 752 of the mode display unit 750 described above are turned off.

  According to such a configuration, it is possible to promptly notify the person viewing the analog meter device 1 that the battery has run out. If the battery is exhausted in the environmental data display mode, the hands 310 and 320 remain displaying the environmental data at the time of the battery exhaustion, and the person viewing the analog meter device 1 represents the current environmental data. It can be misunderstood. In addition, when the battery runs out in the time display mode, the hands 310 and 320 remain displaying the time when the battery runs out, and the person viewing the analog meter device 1 misunderstands that it is the current time. It may be possible to do so. In this respect, according to the present example, since it can be recognized at a glance that the battery has run out, such inconvenience can be avoided.

  Next, the rotational driving of the hands 310 and 320 in the environmental data display mode will be described in detail. As shown in FIG. 11, when the amount of environmental data (temperature) corresponding to the rotation angle of the first pointer 310 per step of the first stepping motor 511 is A, the first pointer 310 converts the environmental data into A Are displayed discretely at intervals. In the illustrated example, the rotation angle of the first pointer 310 per step of the first stepping motor 511 is 0.5 °, and the amount of environmental data corresponding to the rotation angle is 0.2 ° C. The scale 401 of the thermometer is 5 times A, that is, 1 ° C. intervals.

  As shown in FIG. 12, when the amount of environmental data (humidity) corresponding to the rotation angle of the second pointer 320 per step of the second stepping motor 521 is B, the second pointer 320 is the environmental data. Are discretely displayed at intervals of B. In the illustrated example, the rotation angle of the second pointer 320 per step of the second stepping motor 521 is 1 °, and the amount of environmental data corresponding to the rotation angle is 0.5%. The scale 402 of the hygrometer is twice B, that is, 1% intervals.

  Each of the first sensor 210 and the second sensor 220 detects predetermined environmental data as an analog signal. The control means 600 performs analog-digital conversion on each environmental data of the analog signals detected by the first sensor 210 and the second sensor 220 at a predetermined time interval, and the first pointer 310 is located at a position where the converted value is displayed. The movement 500 is controlled so that the second pointer 320 is driven to rotate. In the case of a thermometer or hygrometer that is routinely used in a general lifestyle, the practical time range is 20 seconds or more and 180 seconds or less, and in this example, the interval is 60 seconds. .

  As described above, according to the configuration in which the hands 310 and 320 are rotationally driven at a time interval of 20 seconds or more, unnecessary behavior of the hands 310 and 320, such that the hands 310 and 320 reciprocate in small increments due to slight changes in environmental data. Can be avoided. Power consumption can also be reduced.

  In the time display mode, the first stepping motor 511 makes one step at intervals of 5 seconds, and the first pointer 310 rotates 0.5 °. Further, the second stepping motor 521 makes one step at intervals of 2 minutes, and the second pointer 320 rotates by 1 °.

  Next, the driving range of the first pointer 310 and the second pointer 320 in the environmental data display mode will be described. The analog meter device 1 of this example has the dial 400 on the right side and the left side with the vertical line L (see FIG. 1) intersecting the rotation axes of the first pointer 310 and the second pointer 320 as a boundary. The drive area of the first pointer 310 is provided on one of the right and left sides, and the drive area of the second pointer 320 is provided on the other of the right and left sides of the dial 400. In the example shown in the figure, the driving range of the first pointer 310 is provided on the left side, and the driving range of the second pointer 320 is provided on the right side. Each drive region is provided with the thermometer scale 401 and the hygrometer scale 402 described above.

  The temperature display by the first pointer 310 is not made when the first pointer 310 crosses the vertical line L from the left side to the right side. Further, the humidity indication by the second pointer 320 is not made when the second pointer 320 crosses the vertical line L from the right side to the left side.

  According to such a configuration, the displacement of the indication position of the first pointer 310 due to the backlash of the first drive system 510 and the displacement of the indication position of the second pointer 320 due to the backlash of the second drive system 520 are reduced. Can be prevented. When each of the hands 310 and 320 is driven to rotate beyond the vertical line L, backlash occurs, and thus the displacement of the indicated position is unavoidable. In this example, such inconvenience can be avoided.

  As in this example, when the pointers 310 and 320 are rotationally driven by the stepping motors 511 and 521, the pointers 310 and 320 and the dial 400 are larger than those in which the pointers are moved using the expansion and contraction of the object. Is possible. However, there is a problem that backlash occurs. Since the influence of backlash becomes conspicuous with an increase in size, a configuration for dealing with it is highly important in such an analog meter device 1.

  That is, the analog meter device 1 of the present example devise the layout of the dial 400 for the first pointer 310 and the second pointer 320 having the same rotation center axis by the stepping motors 511 and 521, respectively. As a result, the remarkable effect of more accurately displaying the environmental data by the pointers 310 and 320 is achieved.

  FIG. 13 is a flowchart showing an example of control of the analog meter device 1. First, when a battery is stored in the battery box 140, the power is turned on (Step 1), and the position is detected by the position detecting means 540 (Step 2). The position is also detected when the reset switch 710 is subsequently pressed (Step 3). When the position is detected, the environmental data display mode (Step 5) or the time display mode (Step 6) is set according to the state of the changeover switch 740 (Step 4). These modes are changed by operating the changeover switch 740. When the monitor switch 720 is pressed (Step 7), a monitor display such as displaying past environmental data is performed accordingly (Step 8). When the remaining amount of electric power decreases (Step 9), the pointer is rotated to a predetermined position and stopped (Step 10).

  As described above, the analog meter device of this example is extremely rationally configured as a thermohygrometer that drives a pointer with a motor. In particular, it can be used as a radio-controlled clock by switching modes, which is convenient. In addition, it is needless to say that the configuration of each part in the present example can be appropriately changed in design within the technical scope described in the claims, and is not limited to that illustrated in the drawings. For example, in this example, the temperature and humidity are detected and displayed as the environmental data. Alternatively, other environmental data such as atmospheric pressure may be detected and displayed.

  In the time display mode, the driving range of the first hands 310 and the driving range of the second hands 320 are the same. Therefore, the first pointer 310 and the second pointer 320 need to be configured so that a person viewing the analog meter device 1 can distinguish them. In the case of the analog meter device 1 shown in FIG. 1, the first pointer 310 and the second pointer 320 have the same length, but can be distinguished by having different shapes. In this regard, a general timepiece has a minute hand longer than the hour hand. When pursuing a design as a timepiece, as shown in FIG. 14, the first pointer 310 and the second pointer 320 may be configured to have different lengths.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The mode display means 750 of this example changes the form of the dial 400. The dial displays the environmental data scales 401 and 402 and the clock index 404, and the first form of displaying the environmental data scales 401 and 402 without displaying the clock index 404 (FIG. 15). Reference) and a second form (see FIG. 16) for displaying the clock index 404 without displaying the scales 401 and 402 of the environmental data. In the environment data display mode, the first form is used, and in the time display mode, the second form is used.

  The dial 400 includes a first plate 410 provided with scales 401 and 402 of environmental data and a clock indicator 404, and a second plate 420 partially covering the first plate 410. When one of the second plates 420 is rotated and the scales 401 and 402 of the environmental data appear, the clock index 404 is hidden, and when the clock indices 404 appear, the scales 401 and 402 of the environmental data are hidden. Yes.

  The dial 400 is configured to manually rotate the first plate 410 or the second plate 420, and the switching means for switching between the environmental data display mode and the time display mode corresponds to the rotation of the first plate 410 or the second plate 420. The environmental data display mode and the time display mode are switched.

  In the case of this example, the first plate 410 is fixed inside the housing 100. The second plate 420 is disposed in front of the first plate 410 and can rotate forward and backward within a range of a predetermined rotation angle around the pointer pipes 513 and 523.
