JP 2002-71389 A

  However, in the conventional air conditioner panel as described above, when the power is turned off, the display is simply turned off or the pointer stops, so that it appeals visually to the user. It was missing.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an attractive display device that appeals visually to the user when the power of the pointer-type display device is turned off.

  In order to achieve the above object, according to the first aspect of the present invention, when the power of the pointer type display device is turned off, the control unit (51, 52) moves the pointer unit (3) to the operation operation to be operated. The drive unit (26) is controlled so as to move from a position of the display unit (2, 4) corresponding to the state to a predetermined stop position by a predetermined operation.

  Thereby, when the power source of the pointer type display device is turned off, a visual effect can be achieved by the pointer portion. As a result, an attractive pointer type display device can be provided.

  Note that the case where the power of the pointer type display device is turned off is a case where the control unit receives an instruction to turn off the power when the user turns off the power source switch of the pointer type display device and the power source is turned off. means.

  The stop position can be, for example, the position of the leftmost display unit (so-called zero point).

  Further, as shown in claim 2, one pointer part (3) arranged corresponding to one dial (1) is set as one set, and a plurality of dials (1) and pointer parts (3) are set. If the stop position is the same for all sets of dials (1) and pointer parts (3), for example, all the pointer parts (3) start to move simultaneously. , It can be an operation that moves at the same speed.

  Note that the same stop position means that the position of the pointer portion with respect to the dial face in each set is the same.

  In a similar case, as shown in claim 3, the predetermined operation can be an operation in which all the pointer portions (3) reach the stop position at the same time.

  Specifically, for example, as shown in claim 4, all the pointer portions (3) start to move simultaneously, and all the pointer portions (3) reach the stop position at the same time. The moving speed of 3) is set to a speed corresponding to the moving distance to the stop position.

  That is, by increasing the moving speed of the pointer portion having a longer moving distance, all the pointer portions can simultaneously reach the stop position.

  As another example, as shown in claim 5, all the pointer portions (3) are moved at the same speed, and all the pointer portions (3) reach the stop position at the same time. ), The movement start time of the pointer portion (3) is varied according to the movement distance to the stop position.

  In this way, by varying the timing at which the pointer portion starts moving according to the movement distance to the stop position of the pointer portion, all the pointer portions can reach the zero point at the same time.

  As another example, as shown in claim 6, after all the pointer portions (3) are moved to the same other position different from the stop position, the movement of all the pointer portions (3) is started simultaneously. And move to the stop position at the same speed.

  All pointer parts are moved to the zero point at the same speed after moving all the pointer parts to the rightmost display part position (MAX position), for example. A point can be reached.

  Further, as shown in claim 7, a set of one pointer portion (3) arranged corresponding to one dial (1), and a plurality of sets of dial (1) and pointer portions (3) If the stop position is the same for all the dials (1) and the pointer part (3), one of the plurality of pointer parts (3) starts moving when a predetermined operation is performed. Thereafter, the movement of another pointer part (3) located adjacent to the movement may be started.

  Thereby, for example, the movement of the pointer portion can be made to look like a wave performed by a spectator at the stadium, and the effect of the pointer portion can be enhanced. The movement of the pointer can be started and the movement of the adjacent pointer can be started before the movement is completed, or the movement of the adjacent pointer can be started after the movement is completed.

  Moreover, as shown in Claim 8, it has an illuminating device (24, 28) which illuminates at least one of a dial (1) and a pointer part (3), and a control part (51, 52, 54) is provided. In the case where the lighting device (24, 28) is controlled to be turned on / off, the control device (51, 52, 54) moves the pointer portion (3) to the stop position, and then the lighting device. When (24, 28) is lit, the lighting device (24, 28) can be controlled to be turned off.

  For example, in the case where a plurality of dials and pointer parts are provided, and when the time when the pointer part reaches the zero point is different, the lighting device is turned off in order from the point when the pointer part reaches the zero point. You can also

  Moreover, as shown in Claim 9, it has the illuminating device (24, 28) for pointer type | mold display apparatuses which illuminate at least one of a pointer part (3) and a dial face (1), and a control part (51, 52). , 54) is configured to perform control to turn off the lighting devices (24, 28), the vehicle is turned off when the ignition switch is turned off from on to the control unit (51, 52, 54). The lighting device (24, 28) of the pointer-type display device can be controlled to be turned off in response to the turning off of the lighting device for the instrument included in the measuring instrument.

  When the pointer-type display device is applied to the operation panel of the vehicle air conditioner, for example, when the ignition switch is turned off from on, a timer is started, and the pointer portion can be moved after a predetermined time.

  Alternatively, as shown in claim 10, the control unit (51, 52, 54) receives from the instrument control unit (56) for controlling the vehicle instrument a first synchronization signal relating to lighting of the instrument illumination device. In such a case, the controller (51, 52, 54) is controlled to turn off the illumination device (24, 28) of the pointer-type display device based on the input second synchronization signal. Can be made.

  Further, as shown in claim 11, when the ignition switch is turned from on to off, the control unit (51, 52) displays a pointer type display corresponding to the movement of the indicator part for the instrument of the vehicle instrument. The drive part (26) can be controlled to move the pointer part (3) of the apparatus.

  When the pointer type display device is applied to the operation panel of the vehicle air conditioner, the instrument pointer portion may be moved to a predetermined stop position when the ignition switch is turned off from on. Further, when the ignition switch is turned off from on, the power source of the pointer type display device is turned off.

  Therefore, when the ignition switch is turned off from on, it is preferable to move the pointer portion (3) of the pointer type display device in accordance with the movement of the pointer portion for the instrument.

  For example, the timer can be started when the ignition switch is turned from on to off, and the pointer portion can be moved after a predetermined time.

  Alternatively, as shown in claim 12, the control unit (51, 52) receives from the instrument control unit (56) controlling the vehicle instrument a second synchronization signal related to the movement of the instrument pointer part of the vehicle instrument. In the case of being input, the control unit (51, 52) can control the drive unit (26) based on the input second synchronization signal.

  Further, the invention of each claim described above is operated by the user as shown in claim 13, and the movement target display unit (2, 4) is displayed to the control unit (51, 52) according to the operation. The operation portion (12) has a ring shape with an inner opening and is rotatable, and a dial is provided inside the operation portion (12). (1) It can be applied to a pointer type display device in which a plurality of display units (2, 4) and a pointer unit (3) are arranged.

  In addition, the code | symbol in the bracket | parenthesis of each said means is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

(First embodiment)
In the present embodiment, a case where the pointer type display device is applied to an air conditioner panel of a vehicle will be described as an example. Therefore, in the present embodiment, the car air conditioner corresponds to the operation target of the present invention. In FIG. 1, the front view of the pointer type display apparatus in 1st Embodiment of this invention is shown.

  The pointer type display device of the present embodiment is different from the conventional pointer type display device in the arrangement of the indicator 11 and the dial knob 12, but the basic configuration is the same as that of the conventional pointer type display device. Further, the pointer type display device of the present embodiment is different from the conventional display device in the movement of the pointer when the air conditioner panel is turned off and the way of turning off the illumination of the air conditioner panel.

  As shown in FIG. 1, the pointer-type display device of the present embodiment includes three indicators 11, three bezel dial knobs 12 as operation units, four operation buttons 13, and a cover 14. Yes. Hereinafter, the bezel dial knob 12 is referred to as a bezel 12.

  The bezel 12 has a ring shape with an inner opening. In the present embodiment, as will be described later, the smoke lens 21 is disposed inside the bezel 12. For this reason, the inside of the bezel 12 is not actually opened, but since the smoke lens 21 is transparent, it is visually recognized that the inside of the bezel 12 is opened.

  One indicator 11 is arranged inside each bezel 12. In other words, the bezel 12 is disposed on the outer periphery of the display 11. Therefore, in this embodiment, the indicator 11 and the bezel 12 are integrated.

  Thus, by integrating the display 11 and the bezel 12, it is possible to make it appear to the user that there is no operation switch for operating the operation operation content displayed on the display 11. . Thereby, the external appearance of an air-conditioner panel can be made clear and the confusion of a user's operation by the external appearance being complicated can be suppressed.

  Note that there are three sets of display units and bezels 12 independently, with one display unit 11 and one bezel 12 arranged in this way as one set.

  The three indicators 11 display contents related to the car air conditioner. The three indicators 11 have a dial 1 and a pointer 3 as a pointer portion. On the dial 1, characters, illustrations 2 and scales 4 are arranged in an arc shape. Characters, illustrations 2 and scales 4 correspond to the display unit of the present invention, and the dial 1 and the pointer 3 in one display device correspond to a set of the dial and the pointer unit of the present invention.

  Specifically, the display 11a located on the left side in FIG. 1 displays information related to the blower fan speed, and “OFF”, “LO”, “1”, “2” is displayed on the dial 1. ”And“ HI ”2 and a scale 4 are shown.

  The display 11b located at the center in FIG. 1 displays information related to the speech balloon mode. The dial 1 includes “foot balloon”, “bi-level balloon”, “head balloon”, “foot balloon”. Illustration 2 and scale 4 of “+ defogger speech balloon” and “defogger speech balloon” are shown.

  A display 11c located on the right side in FIG. 1 displays information related to temperature, and the dial 1 shows a number 2 and a scale 4 representing temperature.

  The bezel 12 is a part of a so-called dial switch, and rotates around the center of the bezel 12 along the outer peripheral direction of the bezel 12. Further, the bezel 12 is configured to rotate independently of the dial 1. When the bezel 12 is operated by the user, the pointer 3 points to a desired character or mark 2 and the car air conditioner executes a desired operation.

  FIG. 2 is a diagram for explaining the movement of the bezel 12 and the movement of the pointer 3. FIG. 2 corresponds to FIG. 1, but omits the operation button 13. The bezel 12 can rotate in either the clockwise direction with respect to the dial 1 as indicated by the solid line arrow in FIG. 2 or the counterclockwise direction as indicated by the broken line arrow in FIG. It has become.

  Further, the bezel 12 is rotated by 60 °, for example. That is, as shown in FIG. 2, the bezel 12 stops at a position where the small circle shown on the outer peripheral portion of the dial 1 matches the small circle shown on the bezel 12. These small circles are shown for convenience in FIG. 2 for explanation here.

  In the display 11a that displays the blower fan speed and the display 11b that displays the blowing mode, the pointer 3 moves by 60 °, for example, every time the bezel 12 rotates 60 °. On the other hand, in the indicator 11c that displays the temperature, the pointer 3 moves by one scale every time the bezel 12 rotates 60 °.

  In this way, the rotation angles of the bezel 12 and the pointer 3 can be set to the same or different settings. Note that the rotation angle of the bezel 12 can be arbitrarily set.

  Further, when the car air conditioner is operated by the bezel 12, for example, the indicator 11a that displays the blower fan speed has five settings, and the pointer 3 has “OFF”, “LO”, “1”, One of “2” and “HI” is indicated. On the other hand, when the car air conditioner is automatically controlled, there are five or more settings, and any part between “OFF” and “HI” is indicated.

  As shown in FIG. 1, the operation button 13 is disposed between adjacent bezels 12. The operation buttons 13 are an operation button (A / C button) 13 for setting a car air conditioner, an operation button (AUTO button) 13 for automatic air flow setting, an operation button (rear DEF button) 13 for a defogger, and an air circulation mode setting. An operation button (inside / outside air button) 13 is provided. The area excluding the display 11, the bezel 12, and the operation buttons 13 is covered by the cover 14.

  Next, the mechanical configuration (internal structure) of the pointer type display device will be described. 3, 4, and 5 are respectively a cross-sectional view taken along line AA, a cross-sectional view taken along line BB, and a cross-sectional view taken along line CC in FIG. 1. 3 and 4, the upper side in the figure is the front side of the pointer type display device. The front surface is a surface visually recognized by the user.

  As shown in FIGS. 3 and 5, the pointer type display device of the present embodiment includes a smoke lens 21, a dial 1, a light guide lens 22, and a pointer 3 from the front side of the pointer type display device inside the bezel 12. Arranged in order.

The dial 1 is formed integrally with the light guide lens 22 and is made of a transparent acrylic resin. On the dial 1, letters, marks 2 and scales 4 are printed as a translucent colored layer. The area | region except the translucent colored layer of the dial 1 is made transparent. For this reason, when the dial illumination LED 24 and the later-described pointer illumination LED 28 are turned on, the characters, the mark 2, the scale 4, and the pointer 3 can be visually recognized through the dial 1.
The dial 1 including the light guide lens 22 has a circular shape. This is because the dial 1 is disposed inside the cylindrical bezel 12.

  The dial 1 is separate from the bezel 12 and is fixed to the dial housing 23. Thus, since the dial 1 is fixed to the dial housing 23, the dial 1 does not rotate even if the bezel 12 rotates.

  As shown in FIG. 5, the light guide lens 22 guides light from the dial illumination LED 24 to the dial 1. The dial 1 is illuminated by the light guide lens 22 and the dial illumination LED 24 as an illumination device.

  The dial illumination LED 24 is provided on the first circuit board 25 as shown in FIGS. The first circuit board 25 is fixed to the dial housing 23. Although not shown, the first circuit board 25 is provided with an IC chip as an illumination control unit. The dial illumination LED 24 is disposed below the pointer 3 as shown in FIG.

  The pointer 3 is made of a transparent acrylic resin, and a translucent colored layer is formed over the substantially entire length of the connecting portion with the step motor 26 from the tip thereof, and a light shielding layer is formed in a region excluding the colored layer. The colored layer emits light when a later-described pointer illumination LED 28 is turned on.

  The pointer 3 is connected to a rotating shaft 26a of a stepper motor 26 as a drive unit. The pointer 3 is driven by the stepper motor 26. The stepper motor 26 is provided on the second circuit board 27 for the stepper motor. Further, although not shown, the second circuit board 27 is provided with an IC chip as a drive control unit.

  Further, a pointer illumination LED 28 as an illuminating device for illuminating the pointer 3 is disposed on the back side of the pointer 3. The pointer illumination LED 28 is fixed to the third circuit board 29. The third circuit board 29 is fixed to the dial housing 23. Although not shown, the third circuit board 29 is provided with an IC chip as an illumination control unit.

  The smoke lens 21 is fixed to the bezel 12. The smoke lens 21 is set to have a low transmittance, and when the LED 24 of the dial 1 and the LED 28 of the pointer 3 are turned on, the characters, the mark 2, the scale 4 and the pointer 3 of the dial 1 are visually recognized and turned off. In some cases, the transmittance is set so that the entire dial 1 becomes a black face so that the characters on the dial 1, the mark 2, the scale 4, and the pointer 3 are not visually recognized. Note that the smoke lens 21 can be omitted from the viewpoint of design.

  As shown in FIGS. 3 and 5, the bezel 12 is coupled to the bezel housing 30 via a coupling portion 31. The bezel housing 30 is connected to a rotary switch 32. When the bezel 12 is rotated, the rotary switch 32 is switched via the bezel housing 30.

  The rotary switch 32 is disposed on the fourth circuit board 33 for the rotary switch. Although not shown, the fourth circuit board 33 is provided with an IC chip for reading the position of the bezel 12. As the rotary switch 32, an absolute position signal output switch such as a cord switch can be used.

  Next, the electrical configuration of the pointer type display device of the present embodiment will be described. FIG. 6 shows a block diagram of the configuration of the pointer type display device.

  As described above, the pointer type display device of the present embodiment reads the dial 1, the pointer 3, the stepper motor 26, the dial illumination LED 24, the pointer illumination LED 28, the operation button 13, the bezel 12, the rotary switch 32, and the like. A switch 59 is provided. The read switch 59 is also configured to read a signal from the operation button 13.

  In addition, the pointer-type display device includes a drive control unit 51, a drive signal control unit 52, an air conditioning signal control unit 53, and an illumination control unit 54. The drive control unit 51, the drive signal control unit 52, and the illumination control unit 54 correspond to the control unit of the present invention.

  The drive control unit 51 is an IC chip provided on the second circuit board 27 described above. The drive signal control unit 52 and the air conditioning signal control unit 53 are IC chips provided on the fourth circuit board 33 described above. The illumination control unit 54 is an IC chip provided on the first circuit board 25 and the third circuit board 29 described above.

  The drive control unit 51 controls the stepper motor 26 so that the pointer 3 indicates a predetermined character or illustration 2. The drive control unit 51 outputs a drive instruction signal to each stepper motor 26 corresponding to the three hands 3 based on the drive signal input from the drive signal control unit 52.

  The drive signal control unit 52 controls whether or not to operate the drive control unit 51. The drive signal control unit 52 outputs a drive signal to the drive control unit 51 based on signals input from the air conditioning signal control unit 53 and the vehicle signal control unit 55 separately mounted on the vehicle. Yes. Here, the signal input from the vehicle signal control unit 55 is, for example, a signal indicating that an ignition (IG) switch is ON (ON) or OFF (OFF).

  As will be described later, when the ignition switch is switched from ON to OFF and the power supply of the air conditioner panel is turned off, that is, when the display of the air conditioner panel is terminated, the drive signal control unit 52 moves the pointer 3 to the stop position. The display end processing of the air conditioner panel, such as activation by operation, is executed. For example, the drive signal control unit 52 stores the stop position and the predetermined operation content in a storage unit (not shown), and reads the stop position and the predetermined operation content during the display end process.

  When the signal indicating that the ignition switch is OFF is input from the vehicle signal control unit 55, the drive signal control unit 52 sends the air conditioning system 57 to the air conditioning control unit 58 via the air conditioning signal control unit 53. A signal to end the operation of is output.

  Further, the drive signal control unit 52 outputs a signal for instructing the lighting control unit 54 to turn on / off the lighting devices such as the dial illumination LED 24, the pointer illumination LED 28, and the operation button LED. It is like that.

  The drive signal control unit 52 outputs a signal to a meter control unit 56 that controls a meter such as a speedometer, and a signal is input from the meter control unit 56. For example, when the ignition switch is turned from ON to OFF, a synchronization signal such as the movement of the meter pointer or turning off the meter illumination is input from the meter control unit 56 to the drive signal control unit 52.

  As described later, the signal is exchanged between the drive signal control unit 52 and the meter control unit 56 as described below. When the display on the air conditioner panel is finished, a meter (vehicle instrument) ) Is an analog meter, the movement of the pointer 3 of the air conditioner panel and the movement of the pointer of the meter are associated with each other, or the illumination of the air conditioner panel is turned off in coordination with the illumination of the meter.

  The drive signal control unit 52 has a timer (not shown). For example, this timer starts time measurement when a signal indicating that the ignition switch is OFF is input to the drive signal control unit 52. As will be described later, this timer is used for the display end process of the air conditioner panel as necessary.

  Based on the signal input from the rotary switch 32, the air conditioning signal control unit 53 outputs an air conditioning signal so as to perform predetermined control with respect to the air conditioning control unit 58 that controls the air conditioning system 57 mounted on the vehicle. Is. The air conditioner system 57 includes various sensors, a blower motor, a compressor, a potentiometer, and the like.

  Further, the air conditioning signal control unit 53 outputs a control signal to the drive signal control unit 52 in order to drive the pointer 3 based on the signal input from the rotary switch 32.

  The air conditioning signal control unit 53 receives a control signal from the air conditioning control unit 58. This is because when the air-conditioning control unit 58 automatically controls the air-conditioning system 57, the pointer 3 is driven according to the control. Note that the air conditioning signal control unit 53 has priority over the control signal input from the air conditioning control unit 58 when a signal is input from the rotary switch 32.

  The illumination control unit 54 controls the operation of the dial illumination LED 24 and the pointer illumination LED 28. Based on a signal input from the vehicle signal control unit 55 or the drive signal control unit 52, an operation instruction signal for turning on or off is output to the dial illumination LED 24 and the pointer illumination LED 28.

  Next, the basic operation of the pointer type display device configured as described above will be described. Below, as shown in FIG. 2, the case where a user performs operation which switches a ventilation fan speed from "OFF" to "LO" is demonstrated as an example.

  The user rotates the bezel fan speed of the bezel 12 of the display 11a by 60 ° in the clockwise direction, that is, in the right direction as indicated by the solid line in FIG. As a result, the rotary switch 32 is switched, and as shown in FIG. 6, a signal indicating that the blower fan speed is set to “LO” is input from the rotary switch 32 to the air conditioning signal control unit 53.

  In response to this signal, the air conditioning signal control unit 53 outputs an air conditioning signal indicating that the air conditioning control unit 58 operates at “LO”. Thereby, the air-conditioner system 57 is controlled by the air-conditioning control unit 58 and sets the blower fan speed to “LO”.

  At this time, the air conditioning signal control unit 53 outputs a control signal to the drive signal control unit 52 so that the pointer 3 indicates “LO”.

  Then, after receiving this control signal, the drive signal control unit 52 determines whether or not the drive control unit 51 may be driven based on the signal input from the vehicle signal control unit 55. As a result, when the drive signal control unit 52 determines that the drive control unit 51 may be driven, the drive signal control unit 52 causes the pointer 3 to indicate “LO” to the drive control unit 51. The drive signal is output.

  The drive control unit 51 receives this drive signal and outputs a drive instruction signal to the stepper motor 26. Thereby, the pointer 3 is driven via the stepper motor 26, and the pointer 3 indicates "LO". In this way, the blower fan speed is switched from “OFF” to “LO”.

  Next, the display end process of the air conditioner panel executed by the drive signal control unit 52 will be described. FIG. 7 shows a flowchart of an air conditioner panel display end process executed by the drive signal control unit 52.

  When the user performs an operation of switching the ignition switch from ON to OFF and the ignition switch is switched from ON to OFF, in step 61, a signal indicating that the ignition switch is OFF is input from the vehicle signal control unit 55. Thereby, after step 62, the air conditioner panel is in the power OFF mode. This case corresponds to the case where the power source of the pointer type display device of the present invention is turned off.

  In step 62, when this signal is received, the position corresponding to the control state (operation operation state) of the air conditioner system 57 before the input of this signal, the position of the character 2, the illustration 2 and the scale 4 is zero as a predetermined stop position. A drive signal for moving the pointer 3 by a predetermined operation is output up to a point. Upon receiving this drive signal, the drive control unit 51 outputs the drive signal to the stepper motor 26.

  Here, the zero point and the predetermined operation will be described. FIG. 8 shows a front view of the air conditioner panel. In FIG. 8, the same reference numerals as those in FIG.

  The zero point is a position that points to the leftmost one of characters, illustrations 2 and scales 4 arranged in a circular arc continuously from one end side to the other end side in one display. . This position is, for example, the same position as when the speedometer pointer points to 0 km / k. Specifically, the indicator 11a indicating the blower fan speed is "OFF", and the indicator 11b indicating the blowing mode. Is “foot balloon”, and the temperature indicator 18c is “18 ° C.”.

  As for the predetermined operation, for example, the movement start timing of the pointer 3 of each indicator 11a to 11c can be made the same, and the movement speed of the pointer 3 can be made the same.

  Accordingly, the stepper motor 26 receives the drive signal from the drive control unit 51, and, as shown in FIG. 8, sets the pointers 3 of the respective indicators 11a to 11c to the actual display positions (the pointers 3 indicated by broken lines in the drawing). ) At the same time, and move to the zero point at the same movement speed.

  The reason why the pointer 3 can be moved even when the ignition switch is turned off is that power is continuously supplied from the battery to the drive signal control unit 52, the drive control unit 51, and the stepper motor 26 of the air conditioner panel. It is.

  In step 63, a signal for turning off the dial illumination LED 24 and the pointer illumination LED 28 is output to the illumination control unit 54. Upon receiving this signal, the illumination control unit 54 turns off the dial illumination LED 24 and the pointer illumination LED 28.

  At this time, the timing at which the dial illumination LED 24 and the pointer illumination LED 28 are turned off is, for example, the time when the pointer 3 reaches the zero point.

  The timing at which the pointer 3 of each indicator 11a to 11c returns to the zero point is determined by the position of the pointer 3 when the ignition switch is turned from ON to OFF. The timing to return to the zero point may be scattered. Therefore, the indicators 11a to 11b in which the pointer 3 has moved to the zero point are sequentially turned off. Alternatively, all the indicators 11a to 11c are turned off simultaneously when all the hands 3 reach the zero point.

  As a result, when the ignition switch is turned from ON to OFF and the pointer 3 returns to the zero point from the actual display position, the movement of the pointer 3 can be shown to the user to the end unless the user turns off the illumination. it can.

  Specifically, for example, the dial illumination LED 24 and the pointer illumination LED 28 can be turned off as follows.

  When a signal indicating that the ignition switch is OFF is input in step 61, the drive signal controller 52 determines the distance (angle) from the display position of the pointer 3 to the zero point at that time and the moving speed of the pointer 3. From this, the time taken for the pointer 3 to move to the zero point is calculated.

  In step 63, after the ignition switch is turned off, a signal to turn off the light is output from the drive signal control unit 52 to the illumination control unit 54 after the calculated time. Thereby, when the pointer 3 reaches the zero point, the dial illumination LED 24 and the pointer illumination LED 28 are turned off.

  As described above, the display of the air conditioner panel is completed by executing the display termination process of the air conditioner panel.

  Next, main features of the present embodiment will be described.

  As described above, in the present embodiment, when the ignition switch is turned from ON to OFF, the drive signal control unit 52 and the drive control unit 51 have characters and illustrations 2 corresponding to the actual operation state of the air conditioner system 57. The stepper motor 26 is controlled so that the pointers 3 of the respective indicators 11a to 11c start to move simultaneously from the position of the scale 4 to the zero point and are moved at the same moving speed.

  In this way, when the ignition switch is turned from ON to OFF and the power supply of the air conditioner panel is turned OFF, the pointer 3 is moved from the display position immediately before the power is turned OFF to a different position. Can produce a great performance. As a result, according to the present embodiment, the air conditioner panel can be made attractive.

(Second Embodiment)
In the first embodiment, when the ignition switch is turned from ON to OFF, as the predetermined operation of the hands 3 when the three hands 3 are moved to the zero point, the hands 3 are simultaneously started to move at the same speed. Although the case has been described as an example, other operations can be adopted as in the present embodiment.

  In the first embodiment, as described above, when the display positions of the hands 3 are different when the ignition switch is turned from ON to OFF, the timing at which the three hands 3 return to the zero point varies. On the other hand, in the present embodiment, as a predetermined operation, the case where the timings at which the three hands 3 return to the zero point are the same will be described with three examples.

  (1) FIG. 9 shows a front view of an air conditioner panel for explaining a predetermined operation of the pointer 3 in the first example of the present embodiment. In FIG. 9, the same reference numerals as those in FIG. The first example is a case where the moving speeds of all the hands 3 are the same.

  First, among the three indicators 11a to 11c, when the ignition switch is turned from ON to OFF, the indication position of the indicator 3 starts moving in the order of the indicators 11a to 11c far from the zero point position. . For example, in FIG. 9, since the display position of the pointer 3 of the indicator 11a indicating the fan speed is the farthest from the zero point, the movement of the pointer 3 toward the zero point is started.

  The display position of the pointer 3 is the second and third farthest from the position of the zero point, and the pointer 3 of the other indicator that is moving is the same display position. (The distance to the zero point is the same).

  For example, in FIG. 9, when the pointer 3 of the indicator 11a indicating the fan speed is positioned at “1” as indicated by a broken line, the pointer 3 of the indicator 11b indicating the blowing mode is moved toward the zero point. Let it begin.

  Further, the pointer 3 of the indicator 11a indicating the blower fan speed is positioned between “Lo” and “OFF” as indicated by the broken line, and the pointer 3 of the indicator 11b indicating the blowing mode is “bi-level balloon”. ”And“ foot balloon ”, the pointer 3 of the indicator 11c indicating the temperature is started to move toward the zero point.

  By performing the predetermined operation of the hands 3 in this way, the timings at which the three hands 3 return to the zero point can be made the same.

  (2) FIG. 10 shows a front view of an air conditioner panel for explaining a predetermined operation of the pointer 3 in the second example of the present embodiment. 10, the same reference numerals as those in FIG. 2 are given to the same components as those in FIG. In the second example, the moving speeds of all the hands 3 are the same.

  After all the hands 3 of the three indicators 11a to 11c are moved to the same position, the hands 3 are simultaneously moved to the zero point.

  For example, as shown in FIG. 10, each pointer 3 is moved to the position of MAX (the rightmost end). At this time, the movement start time of each pointer 3 can be the same or different. Then, the pointers 3 are simultaneously moved from the MAX position to the zero point.

  In this case, each pointer 3 moves from the same position to the zero point at the same speed, and therefore reaches the zero point at the same time. In addition, the movements of the pointers 3 match each other, so that the movements of the pointers can have a sense of unity. Note that the position is not limited to the MAX position, and other positions may be used.

  (3) A third example is a case where the moving speed of the pointer 3 is varied. That is, when the timings at which the movements of the pointers 3 are started are the same, according to the distance that the pointers 3 are moved to the zero point position, the pointers 3 are moved to the zero point positions at the same time. Change the speed of movement.

  For example, as shown in FIG. 8, since the moving distance of the pointer 3 to the zero point is long in the order of the indicator 11a indicating the blower fan speed, the indicator 11b indicating the blowing mode, and the indicator 11c indicating the temperature, The moving speed of the pointer 3 is increased in the order of the display 11a indicating the speed, the display 11b indicating the balloon mode, and the display 11c indicating the temperature.

  Thereby, even if it is a case where the timing which starts the movement of each pointer | hook 3 is made the same, the timing which the three pointer | guides 3 return to a zero point can be made the same.

(Third embodiment)
In the present embodiment, a case will be described in which the predetermined operation of the pointer 3 is different from those in the first and second embodiments. As in the present embodiment, the movement start time of the three hands 3 and the time to reach the zero point can be varied. In FIG. 11, the front view of the air-conditioner panel for demonstrating the predetermined operation | movement of the pointer | guide 3 in this embodiment is shown. In FIG. 11, the same reference numerals as those in FIG.

  For example, as shown in FIG. 11, the indicator 11a indicating the blower fan speed located at the left end, the indicator 11b indicating the blowing mode located in the center next to it, and the indicator 11c indicating the temperature located next to the right end. In this order, the pointer 3 starts moving toward the zero point.

  At this time, before the pointer 3 of the left display 11a reaches the zero point, the movement of the pointer 3 of the adjacent display 11b is started, or after the pointer 3 of the left display 11a reaches the zero point, The movement of the pointer 3 of the adjacent indicator 11b can be started.

  In this way, among the pointers 3 of the three indicators 11a to 11c, the pointers 3 are sequentially moved to the zero point in the order of the indicator 11a arranged on one end side to the indicator 11c arranged on the opposite side. Let it begin. Thereby, the movement of the three pointers 3 can be shown as a wave performed by the spectator at the stadium, and an effect by the pointers 3 can be achieved.

(Fourth embodiment)
In the present embodiment, when the ignition switch is turned from ON to OFF, the movement or turn-off of the pointer 3 on the air conditioner panel is changed to the movement or turn-off of the pointer on the analog meter (vehicle instrument having the pointer) mounted on the vehicle. The case where it makes to cooperate is explained. The analog meter is, for example, a speedometer, a tachometer, or the like.

  FIG. 12 shows a flowchart of an air conditioner panel display end process executed by the drive signal control unit 52 in the present embodiment. The display end process of the present embodiment is different from FIG. 7 in the following because step 71 and step 72 between step 61 and step 62 are added in each step shown in FIG. The point will be mainly described.

  After step 61, in step 71, it is determined whether or not a synchronization signal is input from the meter control unit 56.

  This synchronization signal is a signal related to the movement of the pointer of the meter and the turning off of the illumination. That is, when a signal indicating that the ignition switch is ON is input from the vehicle signal control unit 55 to the meter control unit 56, the meter control unit 56 is driven before moving the pointer of the meter or turning off the illumination. This signal is output to the signal control unit 52. This synchronization signal corresponds to the first and second synchronization signals of the present invention.

  If the synchronization signal is input from the meter control unit 56, the determination is YES and the process proceeds to step 62.

  On the other hand, when the synchronization signal is not input from the meter control unit 56, it is determined as NO and the process proceeds to Step 72. In addition, as a case where a synchronization signal is not input from the meter control unit 56, for example, when a signal is not output from the meter control unit 56 to the drive signal control unit 52 due to a failure, or the drive signal control unit 52 and the meter control unit The case where the pointer type display device of this embodiment is mounted on a vehicle that does not communicate with the vehicle 56 is applicable.

  In step 72, it is determined whether the timer of the drive signal control unit 52 has passed a predetermined time. If the predetermined time has passed, the process proceeds to step 62.

  In step 62, as described in the first embodiment, each pointer 3 is returned to the zero point. At this time, for the predetermined operation of the pointer 3, for example, the movement start timing of the pointer 3 of each of the indicators 11a to 11c is made the same, and the moving speed of the pointer 3 is made the same, as in the first embodiment.

  However, in this embodiment, when a synchronization signal is input from the meter control unit 56, the drive signal control unit 52 moves each pointer 3 at a timing based on the synchronization signal. On the other hand, when the timer has passed a predetermined time, the drive signal control unit 52 moves each pointer 3 at that timing.

  Subsequently, in step 63, as described in the first embodiment, the dial illumination LED 24 and the pointer illumination LED 28 are turned off.

  However, in the present embodiment, when a synchronization signal is input from the meter control unit 56, the drive signal control unit 52 and the illumination control unit 54 turn off the lighting devices 24 and 28 at a timing based on the synchronization signal. Let On the other hand, when the predetermined time has elapsed, the drive signal control unit 52 and the illumination control unit 54 turn off the illumination devices 24 and 28 at the timing.

  In this way, the display end process of the drive signal control unit 52 is executed.

  Next, main features of the present embodiment will be described.

  (1) In this embodiment, when it is determined in step 71 that the synchronization signal is input from the meter control unit 56, in step 62, the drive signal control unit 52 determines each pointer at the timing based on the synchronization signal. 3 is controlled to move.

  On the other hand, if it is determined in step 71 that the synchronization signal has not been input from the meter control unit 56, the time is measured by a timer in step 72, and after the predetermined time has elapsed, in step 62, the drive signal control unit 52 is Control is performed so that each pointer 3 is moved.

  As a result, when the ignition switch is turned from ON to OFF, when the pointer of the analog meter is moved to the zero point, when the pointer 3 of the air conditioner panel starts moving to the zero point, the timing of the analog meter It is possible to match (synchronize) the timing when the pointer starts moving to the zero point.

  In addition, the timing at which each pointer 3 returns to the zero point is not limited to this, and the timing at which the pointer of a vehicle meter such as a speedometer or a tachometer returns to the zero point can be matched. In this case, it is preferable that the movement of each pointer 3 is the movement described in the second embodiment.

  If the user can feel that the movement of each pointer 3 is not linked to the movement of the meter pointer, the movement of the pointer 3 of the air conditioner panel and the pointer of the meter will start moving or reach the zero point. The timing may be different.

  (2) In the present embodiment, when the dial illumination LED 24 and the pointer illumination LED 28 are turned off, as in the case of the pointer 3, if it is determined in step 71 that the synchronization signal is input from the meter control unit 56, the step In 63, the drive signal control unit 52 and the illumination control unit 54 control the lighting devices 24 and 28 to be turned off at a timing based on the synchronization signal.

  On the other hand, if it is determined in step 71 that the synchronization signal has not been input from the meter control unit 56, the time is measured by a timer in step 72, and after a predetermined time has elapsed, in step 63, the drive signal control unit 52, illumination The control unit 54 performs control so that each lighting device is turned off.

Thereby, the timing at which the dial illumination LED 24 and the pointer illumination LED 28 are extinguished can be made coincident with the timing at which the instrument illumination device included in the vehicle instrument is extinguished.
Russ.

  In addition, the timing of turning off the dial illumination LED 24 and the pointer illumination LED 28 and the timing of turning off the instrument illumination device included in the vehicle instrument can be shifted by a certain time.

  By causing the drive signal control unit 52 to execute such control, the movement of the pointer 3 and the movement of the meter pointer correspond to each other, that is, interlock with each other, and the timing of turning off the air conditioner panel illumination is adjusted. This can correspond to the timing of turning off.

  In the present embodiment, the case where both the movement of the pointer 3 of the air conditioner panel and the timing of turning off the air conditioner panel are coordinated with the meter has been described as an example. Can also be coordinated with the meter.

  Further, in the present embodiment, the case where both the dial illumination LED 24 and the pointer illumination LED 28 are provided has been described as an example. However, the present invention is applied even when at least one of them is provided. be able to.
