CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority to Korean Patent Application No. 10-2021-0147499, filed Oct. 30, 2021, the entire contents of which is incorporated herein for all purposes by this reference. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present disclosure relates to an operation apparatus having a button used by a user to operate devices included in a vehicle, primarily from the inside of the vehicle. 
     Description of the Related Art 
     In general, vehicles are equipped with an array of devices related to driving to enhance comfort and convenience of a user (driver and/or passenger). These devices are controlled by buttons (or switches) that the user directly manipulates. 
     The buttons may be provided in various forms in an interior of the vehicle. In recent years, as vehicles have come equipped with more functions, the number of buttons disposed in the interior of the vehicle is gradually increasing. The increased number of buttons may give the user an impression that it is difficult and complicated to manipulate the buttons, or may lead to errors in the operation of the devices. In addition, cluttered interior with too many buttons may degrade the aesthetic quality of the interior of the vehicle. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present disclosure has been made keeping in mind the above described problems, is intended to provide an operation apparatus for a vehicle that improves the visibility of a button and the aesthetic value of a vehicle by configuring the button to appear and disappear. 
     Another objective of the present disclosure is to provide an operation apparatus for a vehicle that enables appearing/disappearing of buttons with a simple mechanism. 
     Still another objective of the present disclosure is to provide an operation apparatus for a vehicle that enables reduction of the number of buttons and simplification of the structure. 
     The objectives of the present disclosure are not limited to those mentioned above, and other objectives not mentioned will be clearly understood by those skilled in the art from the following description. 
     In order to achieve the above objective, according to an embodiment of the present disclosure, there is provided an operation apparatus for a vehicle, the operation apparatus including: a panel provided in the vehicle; a first operation module and a second operation module, each capable of moving between a first position and a second position spaced apart from each other a front-back direction through an opening provided in the panel, and each having a button disposed at a front end thereof; and a drive unit having a common drive source, and for moving a selected one of the first operation module and the second operation module by transmitting a drive force of the common drive source.

The drive unit may include: a first contact block provided at a rear of the first operation module and a second contact block provided at a rear of the second operation module; a pressure block configured to move in the orthogonal direction between the first contact block and the second contact block by the drive source, and having a first tapered surface for pressing the first contact block to move forward and a second tapered surface for pressing the second contact block to move forward according to a moving direction; and an elastic member for giving a rearward elastic force to each of the first operation module and the second operation module. 
     The first tapered surface may be formed in a shape rearwardly inclined as the first tapered surface reaches one side of the pressure block from a center of the pressure block along the orthogonal direction, and the second tapered surface may be formed in a shape rearwardly inclined as the second tapered surface reaches another side of the pressure block from the center of the pressure block along the orthogonal direction. 
     The first contact block may have a first contact block tapered surface corresponding to the first tapered surface as a contact surface pressed by the first tapered surface, and the second contact block may have a second contact block tapered surface corresponding to the second tapered surface as a contact surface pressed by the second tapered surface. 
     According to an embodiment of the present disclosure, there is provided an operation apparatus for a vehicle, the operation apparatus including: a panel provided in the vehicle; a first operation module and a second operation module, each capable of moving between a first position and a second position spaced apart from each other in a front-back direction through an opening provided in the panel, and each having a button disposed at a front end thereof; and a drive unit having a common drive source, and for moving a selected one of the first operation module and the second operation module by transmitting a drive force of the drive source. The drive unit may include: a first contact block provided at a rear of the first operation module and a second contact block provided at a rear of the second operation module; a pressure block configured to move in the orthogonal direction between the first contact block and the second contact block by the drive source, and for pressing the first contact block and the second contact block according to a moving direction; and an elastic member for giving a rearward elastic force to each of the first operation module and the second operation module, wherein the first contact block and the second contact block may each have a tapered surface that induces forward movement of the first contact block and forward movement of the second contact block as a contact surface pressed by the pressure block. 
     The operation apparatus for a vehicle according to the embodiment of the present disclosure having the configuration as described above may further include: a sensor for detecting a user&#39;s action state for manipulating the button of the first operation module and the button of the second operation module; and a control unit that controls the drive unit on the basis of a detection signal from the sensor. 
     In addition, at least one of the first operation module and the second operation module may be moved a first distance or a second distance from the first position according to the action state to be located in a front region or a rear region of the second position, and depending on whether at least one of the first operation module and the second operation module is located in the front region or in the rear region, the button may be manipulated to perform a different first operating function and second operating function. Alternatively, at least one of the first operation module and the second operation module may be moved a first distance or a second distance from the first position according to the action state to be located in a front region or a rear region of the second position and may include a light source, and, depending on whether at least one of the first operation module and the second operation module is located in the front region or in the rear region, the button may be manipulated to perform a first operating function and second operating function and the light source may emit light of different colors. 
     The operation apparatus for a vehicle according to the embodiment of the present disclosure having the configuration as described above may further include: a finish skin that provides a finished surface covering a surface of the panel to block the opening, has flexibility, and is configured such that a part blocking the opening is moved together with the button of the first operation module and the button of the second operation module so that a shape of the finished surface is changed according to a movement of the first operation module and a movement of the second operation module. 
     In the operation apparatus for a vehicle according to the embodiment of the present disclosure having the configuration as described above, the surfaces of the buttons may be flush with the panel surface when the first operation module and the second operation module are located in the first position. The second position is located forward of the first position, and the buttons may protrude from the panel surface when the first operation module and the second operation module are located in the second position. At this time, the button of the first operation module and the button of the second operation module may protrude more when the first operation module and the second operation module are located in the front region among the front region and the rear region of the second position. Alternatively, the second position is rearward of the first position, and the buttons may be recessed from the panel surface when the first operation module and the second operation module are located in the second position. At this time, the button of the first operation module and the button of the second operation module may be recessed more when the first operation module and the second operation module are located in the rear region among the front region and the rear region of the second position. 
     Technical solutions will become more specific and clear from the examples, drawings, etc. described below. In addition, various solutions other than the aforementioned ones may be additionally suggested below. 
     According to an embodiment of the present disclosure, depending on the positions of operation modules, buttons may be in a state easily seen by a user (for example, a state in which a first operation module or a second operation module is located in a second position and the button protrude from the surface of a panel) or in a state difficult to be seen by the user (for example, a state in which the first operation module and the second operation module are all located in a first position and the surfaces of the buttons are flush with the surface of the panel). Accordingly, regarding the buttons, it is possible to provide better visibility and improved design. 
     In addition, according to an embodiment of the present disclosure, since the buttons appear and disappear by a common drive source, an appearing/disappearing drive mechanism for the buttons can be simplified, thereby reducing costs. 
     Furthermore, according to an embodiment of the present disclosure, since different functions are performed depending on the positions of the buttons, it is possible to reduce the number of buttons to be applied to the vehicle, thereby preventing the interior of a vehicle from being cluttered with many buttons. 
     The effects of the present disclosure are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from this specification and accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting the present disclosure. As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises”, “includes”, or the like when used herein, specify the presence of stated features, steps, operations, elements, components, or combinations thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, or combinations thereof. 
     According to an embodiment of the present disclosure, an operation apparatus for a vehicle, a vehicle including the same, etc. may be provided. The operation apparatus may be used to operate various devices included in a vehicle. For example, devices operated by the operation apparatus (hereinafter referred to as a device to be operated) may include a navigation device, an air conditioning device, a sound device, a lighting device, a door lock device, a door opening or closing device, a motor/engine starting device, a driving speed control device, etc. Therefore, the vehicle according to the embodiment of the present disclosure may include the operation apparatus and at least one or more devices to be operated by the operation apparatus. The operation apparatus and the device to be operated may be electrically connected to each other. 
     The operation apparatus is installed in a vehicle and includes a button manipulated by a user. The operation apparatus may be provided to constitute a part of a vehicle. The part to which the operation apparatus is applied may be primarily an interior part of a vehicle. For example, the interior part may be a door trim, a ceiling panel, a dashboard, a console, a seat, an armrest, and the central part of a steering wheel (hub), etc. Embodiments of the present disclosure will be mainly focused on application of the operation apparatus to an interior part of a vehicle. 
     The structure and operation of the operation apparatus are exemplified in  FIGS.  1  to  6   . 
     As illustrated in  FIG.  1   , the operation apparatus includes: a panel  1  constituting an interior part of a vehicle; and at least one operation module assembly  5  provided on the panel  1 . 
     The panel  1  has a panel surface and a panel back surface. The panel  1  may be configured such that, depending on the type, shape, etc. of the interior part, the panel surface provides only a part of the surface of an interior part or the panel surface provides the entire surface of the interior part. The panel  1  has a first opening  2 A (shown in  FIGS.  4 - 6   ) and a second opening  2 B. Each of these openings  2 A,  2 B is provided to penetrate the panel  1  through the panel surface and the panel back surface. The operation module assembly  5  includes a first operation module  10 A (shown in  FIGS.  4 - 6   ) and a second operation module  10 B. The operation modules  10 A and  10 B respectively include buttons  11 A (shown in  FIGS.  4 - 6   ) and  11 B manipulated by a user and are configured to operate, for example in a touch manner. The first button  11 A, which is a button of the first operation module  10 A, is disposed at the front end of the first operation module  10 A, and the second button  11 B, which is a button of the second operation module  10 B, is disposed at the front end of the second operation module  10 B, thus the first operation module  10 A and the second operation module  10 B have the front parts including the front ends composed of the button  11 A and the button  11 B, respectively. The first operation module  10 A and the second operation module  10 B are moved in the front-back direction (refer to the Y-axis direction) with respect to the first opening  2 A and the second opening  2 B, respectively, of the panel  1 , and the buttons  11 A and  11 B that move together with the operation modules  10 A and  10 B, respectively, may appear and disappear through the first opening  2 A and the second opening  2 B, respectively. In order to make the buttons  11 A and  11 B appear and disappear, the buttons  11 A and  11 B may protrude in an embossed form with respect to the panel surface to reveal their positions and/or shapes (see 
       FIGS.  5  and  6   ). The buttons  11 A and  11 B may be recessed in an engraved form rather than an embossed form with respect to the panel surface in order to reveal their positions and/or shapes. Depending on the implementation conditions, etc., the first opening  2 A and the second opening  2 B may be provided in one integrated form, and the first operation module  10 A and the second operation module  10 B may be moved in the front-back direction (refer to the Y-axis direction) with respect to the integrated opening. 
     The operation apparatus further includes a skin  30  covering the surface of the panel and the buttons  11 A and  11 B to provide a finished surface. The skin  30  may be sized to cover some or all of the panel surface including the openings  2 A and  2 B of the panel  1 . The skin  30  is flexible so that when the buttons  11 A and  11 B are moved, each of the parts covering the buttons  11 A and  11 B (the parts that block the openings  2 A and  2 B) is deformed by the buttons  11 A and  11 B, respectively, and the shape of the finished surface may change. For example, parts covering the buttons  11 A and  11 B may be protruded by the buttons  11 A and  11 B in a generally flat shape of the finished surface (refer to  FIGS.  5  and  6   ). When the finished surface is restored to the generally flat shape, the shapes of the buttons  11 A and  11 B are hidden, and thus it is possible to prevent the interior of the vehicle from being cluttered with the buttons  11 A and  11 B (see  FIGS.  1  and  4   ). 
     The skin  30  may be bonded to the panel surface. In addition, the skin  30  may be precisely deformed and moved together with the buttons  11 A and  11 B when each of the parts covering the buttons  11 A and  11 B (the parts that block the openings  2 A and  2 B) is bonded to the surfaces of the buttons  11 A and  11 B, respectively. In particular, bonding of the skin  30  to the surface of the buttons  11 A and  11 B may be desired when the buttons  11 A and  11 B are retractable against the panel surface. The bonding of the skin  30  to the panel surface and/or the bonding of the skin  30  to the surfaces of the buttons  11 A and  11 B may be made firmly by an adhesive or the like. 
     As illustrated in  FIGS.  1 ,  4 ,  5  and  6   , the operation module assembly  5  further includes a base  21  disposed at a rear of the panel  1 , and a base cover  22  detachably coupled to the base  21  at a rear of the base  21 . The base  21  and the base cover  22  constitute the case  20 . The base  21  and the base cover  22  coupled to each other are configured to provide an accommodating space  23  therebetween which is partially or wholly blocked from the outside. The base  21  may be mounted on the back side of the panel by means of fastening elements  24  such as bolts. The base  21  has a first through region  25 A and a second through region  25 B respectively facing the openings  2 A and  2 B of the panel  1 . For example, the through regions  25 A and  25 B may be provided in the form of a hole. Depending on implementation conditions, etc., the first through region  25 A and the second through region  25 B may be provided in an integrated form. 
     The first operation module  10 A and the second operation module  10 B are, in a state of being inserted into the first through region  25 A and the second through region  25 B respectively of the base  21 , provided to be movable between a first position and a second position spaced apart from each other in the front-back direction (refer to the Y-axis direction) through the opening  2  of the panel  1 . The first position is a position where the buttons  11 A and  11 B are accommodated in the openings  2 A and  2 B, and the buttons  11 A and  11 B are formed such that the surfaces thereof are flush with the panel surface when the operation modules  10 A and  10 B are located in the first position. The second position is located forward of the first position and is a position where the buttons  11 A and  11 B protrude from the panel surface. When the operation modules  10 A and  10 B are located in the first position, the skin  30  may hide the buttons  11 A and  11 B by providing a finished surface in a generally flat shape (see  FIGS.  1  and  4   ). When the operation modules  10 A and  10 B are moved to the second position so that the buttons  11 A and  11 B protrude from the panel surface, the skin  30  may be deformed into a shape in which parts covering the buttons  11 A and  11 B protrude by the buttons  11 A and  11 B to reveal the positions of the buttons  11 A and  11 B (see  FIGS.  5  and  6   ). Depending on implementation conditions, etc., the second position may be a position in which the buttons  11 A and  11 B are recessed with respect to the panel surface while being located rearward of the first position. In this case, when the operation modules  10 A and  10 B are moved to the second position, the skin  30  may be deformed into a shape in which the parts covering the buttons  11 A and  11 B are recessed to reveal the positions of the buttons  11 A and  11 B. 
     The first operation module  10 A and the second operation module  10 B are arranged at regular intervals so as to be spaced apart from each other in the left-right direction (refer to the X-axis direction), which is one of the directions orthogonal to the front-back direction (refer to the Y-axis direction). The first opening  2 A and the second opening  2 B for the protruding and retracting of the first operation module  10 A and the second operation module  10 B, and the first through region  25 A and the second through region  25 B into which the first operation module  10 A and the second operation module  10 B are inserted are also arranged in the left-right direction (refer to the X-axis direction). For example, each of the first operation module  10 A and the second operation module  10 B, the first opening  2 A and the second opening  2 B, and the first through region  25 A and the second through region  25 B may be arranged in the up-down direction (refer to the Z-axis direction) as another direction orthogonal to the front-back direction, or in another direction other than the left-right direction and the up-down direction. 
     Although not shown, the first operation module  10 A and the second operation module  10 B may be precisely moved in the front-back direction (refer to the Y-axis direction) with respect to the openings  2 A and  2 B by a first guide and a second guide, respectively. For example, each of the guides may include guide pins provided on the base  21 . The guide pins of the first guide for guiding the first operation module  10 A and the guide pins of the second guide for guiding the second operation module  10 B may be respectively arranged around the first through region  25 A and the second through region  25 B in the accommodating space  23 . The first operation module  10 A and the second operation module  10 B each have guide holes into which the guide pins of the first guide are inserted and the guide pins of the second guide are inserted, and may be moved according to the guidance of the guide pins. 
     The operation module assembly  5  further includes a drive unit  40  for moving the operation modules  100 A and  10 B in the front-back direction with respect to the openings  2 A and  2 B to position the operation modules  10 A and  10 B in the first position or the second position. For reference, the drive unit  40  is schematically represented in  FIGS.  4  to  6   . 
     By the drive unit  40 , the operation modules  10 A and  10 B may move forward from the first position to the second position. Accordingly, when the operation modules  10 A and  10 B are located in the second position, the buttons  11 A and  11 B protrude from the panel surface, and the skin  30  is deformed into a shape in which parts covering the buttons  11 A and  11 B protrude (see  FIGS.  5  and  6   ). Of course, if the second position is a position located rearward of the first position and the buttons  11 A and  11 B are recessed with respect to the panel surface, the skin  30  may be deformed into a shape in which the parts covering the buttons  11 A and  11 B are recessed when the operation modules  10 A and  10 B are located in the second position. Conversely, by the drive unit  40 , the operation modules  10 A and  10 B may be move backward from the second position to the first position. Accordingly, when the operation modules  10 A and  10 B are located in the first position, the surfaces of the buttons  11 A and  11 B are flush with the panel surface, and the skin  30  is restored to provide a generally flat finished surface (see  FIGS.  1  and  4   ). 
     Referring to  FIGS.  1  and  2   , the operation apparatus further includes: a user detection sensor  50  for detecting a user&#39;s action state for manipulating the buttons  11 A and  11 B; and a control unit  60  for controlling the operation modules  10 A and  10 B and the drive unit  40  on the basis of a detection signal from the user detection sensor  50 . 
     As shown in  FIG.  1   , the user detection sensor  50  may be provided on the side of the openings  2 A,  2 B in the panel surface. The user detection sensor  50  may include at least one sensing element. For example, the user detection sensor  50  may include a first sensing element for detecting a user&#39;s action state for manipulating the first button  11 A and a second sensing element for detecting a user&#39;s action state for manipulating the second button  11 B, and the first and second sensing elements may be respectively disposed around the first opening  2 A and the second opening  2 B. Alternatively, the user detection sensor  50  may be configured to detect both the user&#39;s action state for manipulating of the first button  11 A and the user&#39;s action state for manipulating of the second button  11 B using a single sensing element. In the user detection sensor  50 , the sensing element may be a proximity sensor that detects whether a user&#39;s body, such as a hand, is in proximity to the first button  11  and to the second button  11 B. To be specific, the user detection sensor  50  may be an optical proximity sensor, a magnetic proximity sensor, an ultrasonic proximity sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, or the like. For reference, among these sensors, the optical proximity sensor may include a light emitting element and a light receiving element receiving light from the light emitting element. The light emitting element may be a light emitting diode, and the light receiving element may be a phototransistor. 
     When a detection signal is input from the user detection sensor  50  while the operation modules  10 A and  10 B are located in the first position, the control unit  60  determines that the user attempts to manipulate the first button  11 A or the second button  11 B, and moves the first operation module  10 A or the second operation module  10 B from the first position to the second position by the control of the drive unit  40  (see  FIGS.  5  and  6   ). When the button  11  is not manipulated for a preset time after the first operation module  10 A or the second operation module  10 B is located in the second position, the control unit  60  determines that the user does not want to manipulate the button  11 A or the button  11 B, and moves the first operation module  10 A or the second operation module  10 B from the second position to the first position by the control of the drive unit  40  (see  FIGS.  1  and  4   ). 
     The operation modules  10 A and  10 B are kept in an inactive state in the first position and are kept in an active state in the second position. To switch the state of the operation modules  10 A and  10 B, the control unit  60  may set the operation modules  10 A and  10 B to be in an inactive state when the operation modules  10 A and  10 B are in the first position, and control the operation modules  10 A and  10 B to be in an active state when the operation modules  10 A and  10 B are in the second position. Due to the configuration that allows switching between active and inactive states with respect to the operation modules  10 A and  10 B, the user may manipulate the buttons  11 A and  11 B to operate a device to be operated when the operation modules  10 A and  10 B are located in the second position, and while the operation modules  10 A and  10 B are waiting in the first position, it is possible to prevent the buttons  11 A and  11 B from being actuated unintentionally by the user, thereby preventing a device to be operated from being unintentionally operated. 
     As illustrated in  FIGS.  4 ,  5  and  6   , the first operation module  10 A further includes a light source  12 A for providing light, and the second operation module  10 B includes a light source  12 B for providing light. The light sources  12 A and  12 B may be built into the buttons  11 A and  11 B to emit the lights toward the surfaces of the buttons  11 A and  11 B. The light sources  12 A and  12 B may provide lights of various colors. For example, the light sources  12 A and  12 B may include at least one light emitting diode. As illustrated in  FIG.  3   , the first button  11 A and the second button  11 B are provided with light-transmitting areas  13 A and  13 B, respectively, through which lights from the light sources  12 A and  12 B pass and light-blocking areas  14 A and  14 B, respectively, that block lights from the light sources  12 A and  12 B on the surface thereof. Each of the light-transmitting areas  10 A and  13 B may be formed to have the shape of characters and/or figures indicating the function of the buttons  11 A and  11 B. In the operation modules  10 A and  10 B, the light sources  12 A and  12 B are maintained in an off state in the first position, and the light sources  12 A and  12 B are maintained in an on state in the second position. For this change of state of the light sources  12 A and  12 B, the control unit  60  may control the light sources  12 A and  12 B to be turned off when the operation modules  10 A and  10 B are located in the first position, and control the light sources  12 A and  12 B to be turned on when the operation modules  10 A and  10 B are located in the second position. Due to the configuration that allows switching between off and on states with respect to the light sources  12 A and  12 B, when the operation modules  10 A and  10 B are located in the second position, the active states of the operation modules  10 A and  10 B and the positions of the buttons  11 A and  11 B may be more accurately recognized by the user. 
     The skin  30  has a constant light transmittance so that light from the light sources  12 A and  12 B may pass through the skin  30 , and although the user detection sensor  50  is provided around the openings  2 A and  2 B in the panel surface, the user&#39;s action state for manipulating the buttons  11 A and  11 B may be detected by the user detection sensor  50 . For example, the skin  30  may be a sheet having light transmittance by being woven with fibers having flexibility. 
     As illustrated in  FIGS.  4  to  6   , the drive unit  40  is configured to have a common drive source  43 , and to move the selected one of the first operation module  10 A and the second operation module  10 B in the front-back direction (refer to the Y-axis direction) by transmitting a drive force from the common drive source  43 . 
     As previously described, the first operation module  10 A and the second operation module  10 B are arranged in the left-right direction (refer to the X-axis direction). The drive source  43  includes a moving body  44  that linearly moves in a left-right direction that is the same as the arrangement direction of the first operation module  10 A and the second operation module  10 B. The drive source  43  may be a linear actuator including the moving body  44 . The moving body  44  may be moved more precisely in the left-right direction by a guide (X-axis guide,  49 ). The drive source  43  may further include a rotary motor  45 . The rotation motor  45  has male thread formed on the outer periphery of a motor shaft, and the moving body  44  may have a female screw hole for screwing with the male thread formed on the motor shaft of the rotary motor  45 . At this time, rotation of the moving body  44  may be restricted by the guide  49  guiding the left-right movement of the moving body  44  or a separate guide. Accordingly, the moving body  44  may be moved to the left or moved to the right according to the rotation direction of the rotary motor  45 . 
     The drive unit  40  further includes a first contact block  41 A, a second contact block  41 B, a pressure block  46 , a first elastic member  48 A, and a second elastic member  48 B. 
     The first contact block  41 A is provided at the rear of the first operation module  10 A, and the second contact block  41 B is provided at the rear of the second operation module  10 B. The first contact block  41 A and the second contact block  41 B are arranged in the same left-right direction (refer to the X-axis direction) as the arrangement direction of the first operation module  10 A and the second operation module  10 B. The pressure block  46  is disposed in the region between the first contact block  41 A and the second contact block  41 B, is moved in the left-right direction by the drive source  43 , and comes into contact with the first contact block  41 A to press the first contact block  41 A or comes into contact with the second contact block  41 B to press the second contact block  41 B, depending on the moving direction. The first contact block  41 A and the second contact block  41 B may protrude rearward from the rear portion of the first operation module  10 A and the rear portion of the second operation module  10 B, respectively. The pressure block  46  may be coupled to the moving body  44  of the drive source  43  to move together with the moving body  44 . 
     The first contact block  41 A has a tapered surface  42 A that induces forward movement of the first contact block  41 A as a contact surface pressed by the pressure block  46  when in contact with the pressure block  46 , and the second contact block  41 B has a tapered surface  42 B that induces forward movement of the second contact block  41 B as a contact surface pressed by the pressure block  46  when in contact with the pressure block  46 . The pressure block  46  has a first tapered surface  47 A that presses the first contact block  41 A when in contact with the first contact block  41 A to move the first contact block  41 A forward, and a second tapered surface  47 B that presses the second contact block  41 B when in contact with the second contact block  41 B to move the second contact block  41 B forward. 
     When the pressure block  46  is moved toward the first contact block  41 A in the left-right direction (refer to the X-axis direction) by the drive source  43 , the first tapered surface  47 A comes into contact with the tapered surface  42 A of the first contact block  41 A, and when the pressure block  46  is moved toward the second contact block  41 B in the left-right direction by the drive source  43 , the second tapered surface  47 B comes into contact with the tapered surface  42 B of the second contact block  41 B. The tapered surface  42 A of the first contact block  41 A and the first tapered surface  47 A of the pressure block  46  are formed to have inclinations corresponding to each other, while the tapered surface  42 B of the second contact block  41 B and the second tapered surface  47 B of the pressure block  46  are formed to have inclinations corresponding to each other. To be specific, in order to move the contact blocks  41 A,  41 B forward, the first tapered surface  47 A of the pressure block  46  is formed in a shape rearwardly inclined at a constant angle as the first tapered surface  47 A reaches the first contact block  41 A side from a center of the pressure block  46  in the left-right direction, and the second tapered surface  47 B of the pressure block  46  is formed in a shape rearwardly inclined at a constant angle as the second tapered surface  47 B reaches the second contact block  41 B side from center of the pressure block  46  in the left-right direction. 
     The first tapered surface  47 A and the second tapered surface  47 B may be disposed on the left front portion and right front portion of the pressure block  46 , respectively. The tapered surface  42 A of the first contact block  41 A may be disposed opposite to the first tapered surface  47 A at a rear portion of the first contact block  41 A. The tapered surface  42 B of the second contact block  41 B may be disposed opposite to the second tapered surface  47 B at the rear portion of the second contact block  41 B. The tapered surface  42 A of the first contact block  41 A and the tapered surface  42 B of the second contact block  41 B, as well as the first tapered surface  47 A and the second tapered surface  47 B of the pressure block  46  are for converting the pressing direction of the pressure block  46  from the left-right direction (refer to the X-axis direction) to the front-back direction (refer to the Y-axis direction). Depending on implementation conditions, etc., the tapered surface  42 A of the first contact block  41 A and the tapered surface  42 B of the second contact block  41 B may be excluded from the drive unit  40 , and the first tapered surface  47 A and the second tapered surface  47 B of the pressure block  46  may be excluded from the drive unit  40 . 
     At least one first elastic member  48 A is interposed between the first operation module  10 A and the base  21  to give an elastic force to the first operation module  10 A rearward along the front-back direction (refer to the Y-axis direction), while at least one second elastic member  48 B is interposed between the second operation module  10 B and the base  21  to give an elastic force to the second operation module  10 B rearward along the front-back direction. For example, the first elastic member  48 A and the second elastic member  48 B may be coil springs. 
     The drive unit  40  configured as described above may stand by in a state in which the first tapered surface  47 A is spaced apart from the tapered surface  42 A of the first contact block  41 A and the second tapered surface  47 B is spaced apart from the tapered surface  42 B of the second contact block  41 B as the pressure block  46  is located in the middle of the region between the first contact block  41 A and the second contact block  41 B. At this time, the operation modules  10 A,  10 B are both moved rearwardly in the front-back direction by the action of the elastic members  48 A,  48 B, and are maintained in the first position (see  FIG.  4   ). 
     In this state, when the drive source  43  moves the pressure block  46  in the left-right direction (refer to the X-axis direction) toward the first contact block  41 A so that the first tapered surface  47 A of the pressure block  46  presses the tapered surface  42 A of the first contact block  41 A, the first operation module  10 A is moved forward (move from the first position to the second position) along the front-back direction (refer to the Y-axis direction), and the first elastic member  48 A is compressed. This is the operation of the drive unit  40  by the control of the control unit  60  when the user detection sensor  50  detects a user&#39;s action state for manipulating the first button  11 A. By this operation, the first operation module  10 A is positioned in the second position (active state, the first light source is turned on), and the second operation module  10 B remains in the first position as it is (inactive state, the second light source turned off) (see  FIG.  5   ). 
     On the other hand, when the drive source  43  moves the pressure block  46  in the left-right direction (refer to the X-axis direction) toward the second contact block  41 B so that the second tapered surface  47 B of the pressure block  46  presses the tapered surface  42 B of the second contact block  41 B, the second operation module  10 B is moved forward (move from the first position to the second position) along the front-back direction (refer to the Y-axis direction), and the second elastic member  48 B is compressed. This is the operation of the drive unit  40  by the control of the control unit  60  when the user detection sensor  50  detects a user&#39;s action state for manipulating the second button  11 B. By this operation, the first operation module  10 A remains in the first position as it is (inactive state, the first light source is turned off), and the second operation module  10 B is positioned in the second position (active state, the second light source is turned on) (see  FIG.  6   ). 
     When the button  11 A or  11 B is not actuated for a set time after the first operation module  10 A or the second operation module  10 B is positioned in the second position, the pressure block  46  moved toward the first contact block  41 A or the second contact block  41 B in the left-right direction (refer to the X-axis direction) is moved to the middle of the region between the first contact block  41 A and the second contact block  41 B by the drive source  43 , and the first operation module  10 A or the second operation module  10 B in the second position is moved rearward (move from the second position to the first position) along the front-back direction (refer to the Y-axis direction) by the restoring force of the elastic member  48 A or  48 B. 
     Meanwhile, the operation apparatus may have a front region and a rear region, in which the second position with respect to the first operation module  10 A and the second position with respect to the second operation module  10 B are positioned relatively forward and positioned relatively rearward, respectively. Of course, the rear region is located behind the front region. The operation apparatus is configured such that, the buttons  11 A and  11 B may protrude at different heights as the operation modules  10 A and  10 B are moved from the first position to a first distance or a second distance to be located in the front region or the rear region of the second position. That is, the buttons  11 A and  11 B may protrude to a second height when the operation modules  10 A and  10 B are located in the front region, and may protrude to a first height that is lower than the second height when the operation modules  10 A and  10 B are located in the rear region. In this case, if the second position is a position located rearward of the first position and a position where the buttons  11 A and  11 B are recessed with respect to the panel surface, the buttons  11 A and  11 B may be recessed to different heights (depths). 
     In this regard, the operation apparatus is configured such that, the operation modules  10 A and  10 B may be moved the first distance from the first position according to the detection signal of the user detection sensor  50  to be located in the rear region of the second position, and the buttons  11 A and  11 B may protrude to the first height, or the operation modules  10 A and  10 B may be moved the second distance from the first position according to the detection signal of the user detection sensor  50  to be located in the front region of the second position, and the buttons  11 A and  11 B may protrude to the second height. In addition, depending on whether the operation modules  10 A and  10 B are located in the rear region or in the front region, the buttons  11 A and  11 B may be manipulated to perform a first function and a second function as different operating functions. For example, a first device to be operated and a second device to be operated may be operated as respective operations corresponding to the first function and the second function of the first button  11 A, and a third device to be operated and a fourth device to be operated may be operated as respective operations corresponding to the first function and the second function of the second button  11 B. As another example, when the devices to be operated are a sound device and a lighting device, the volume increase and volume decrease of the sound device are performed as respective operations corresponding to the first function and the second function of the first button  11 A, while the lighting device may be turned on and off as each operation corresponding to the first function and the second function of the second button  11 B. With this configuration, since multiple functions may be performed with one button, the number of buttons required to be provided may be reduced. 
     To implement multiple functions with one button, the user detection sensor  50  may detect, on the basis of the user&#39;s action state for manipulating the first button  11 A, whether a user&#39;s hand or the like that is in the proximity of the first button  11 A is located in a first range or in a second range based on the first button  11 A, and on the basis of the user&#39;s action state for manipulating the second button  11 B, whether a user&#39;s hand or the like that is in the proximity of the second button  11 B is located in a third range or in a fourth range based on the second button  11 B. For example, the region of the first range and the region of the third range may be a range in which the user&#39;s hand or the like that is in the proximity of the first button  11 A is at a relatively close distance based on the first button  11 A and a range in which the user&#39;s hand or the like that is in the proximity of the second button  11 B is at a relatively close distance based on the second button  11 B, respectively, and the region of the second range and the region of the fourth range may be a range in which the user&#39;s hand or the like that is in the proximity of the first button  11 A is at a relatively long distance based on the first button  11 A and a range in which the user&#39;s hand or the like that is in the proximity of the second button  11 B is at a relatively long distance based on the second button  11 B, respectively. As another example, the first range and the second range may be an upper region and a lower region based on the first button  11 A, and the third range and the fourth range may be an upper region and a lower region based on the second button  11 B. 
     In this regard, when the user detection sensor  50  detects that the user&#39;s hand is positioned in the first range (or the second range) while the operation modules  10 A and  10 B are located in the first position, the control unit  60  may determine that the user is attempting to manipulate a device so that the first function (or the second function) of the first button  11 A is performed and may move the first operation module  10 A to the rear region (or the front region) of the second position by the control of the drive unit  40 . Alternatively, when the user detection sensor  50  detects that the user&#39;s hand is positioned in the third range (or the fourth range), the control unit  60  may determine that the user is attempting to manipulate another device so that the first function (or the second function) of the second button  11 B is performed and may move the second operation module  10 B to the rear region (or the front region) of the second position by the control of the drive unit  40 . 
     In addition, by the control unit  60 , the operation modules  10 A and  10 B may be maintained in a state in which the light sources  12 A and  12 B emit lights of different colors depending on whether the operation modules  10 A and  10 B are located in the front region or in the rear region of the second position. The first light source  12 A may emit the light of a first color and the light of a second color depending on whether the first operation module  10 A is located in the rear region or in the front region, respectively, while the second light source  12 B may emit the light of a third color and the light of a fourth color depending on whether the second operation module  10 B is located in the rear region or in the front region, respectively. Due to this configuration, it is possible for the user to more accurately recognize whether the operation modules  10 A and  10 B are located in the front region or in the rear region.
