     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, the embodiments of the present invention will be described with reference to the drawings. 
     Embodiment 1 
       FIG. 1  illustrates the configuration of a watch according to Embodiment 1 of the present invention. This watch is a wristwatch worn on a wrist, and includes a watch body  1 . A watch face  2 , three pointers  3   a  to  3   c , a protection member  4 , a display  5 , and a belt  6  are attached to the watch body  1 . 
     The watch body  1  is configured to support each part such as the watch face  2 , and has a shape extending along the wrist. The watch body  1  may be made of a material with a high rigidity, for example, metal. In addition, the watch body  1  includes an information input unit (not shown) used to input, for example, music information and output music by wireless. The watch face  2  has a discoid shape and is attached to the watch body  1 . A decoration  8  is displayed on an upper surface  7  of the watch face  2  together with the time. 
     The pointers  3   a  to  3   c  indicate the time displayed on the upper surface  7  of the watch face  2 , and are provided to rotate in the plane parallel to the watch face  2 . The pointer  3   a  is a second hand indicating the second on the watch face  2 . The pointer  3   b  is a minute hand indicating the minute on the watch face  2 . The pointer  3   c  is an hour hand indicating the hour on the watch face  2 . The protection member  4  is configured to protect the watch face  2 , and provided to cover the watch face  2 . An open and close member  9  is provided on the edge of the protection member  4 . This open and close member  9  opens and closes the protection member  4  so as to rotate the protection member  4 . 
     The display  5  is configured to display information to the outside, which may be a liquid crystal monitor. The display  5  may be connected to, for example, the information input unit of the watch body  1 , and display music information such as the title of a song inputted to the information input unit. The belt  6  is attached to a pair of opposite edges of the watch body  1  and worn around the wrist to fix the watch body  1  to the wrist. 
     Next, the configuration of the pointers  3   a  to  3   c  will be described. As illustrated in  FIG. 2 , the pointers  3   a  to  3   c  include extension portions  10   a  to  10   c , and support portions  11   a  to  11   c , respectively. The extension portions  10   a  to  10   c  are provided to sandwich the watch face  2  between the extension portions  10   a  to  10   c  and the watch body  1 . Here, an opening  12  is formed near the center of the watch face  2 . The extension portions  10   a  to  10   c  extend from the opening  12  toward the edge of the watch face  2  parallel to the upper surface  7  of the watch face  2 . In this case, the extension portions  10   a  to  10   c  are disposed at different positions apart from each other in a direction orthogonal to the watch face  2 , and are spaced from the watch face  2  in order of the extension portions  10   a ,  10   b , and  10   c.    
     The support portions  11   a  to  11   c  are provided to protrude from the watch body  1  into the upper surface  7  of the watch face  2  via the opening  12 , and front ends of the support portions  11   a  to  11   c  are connected to the extension portions  10   a  to  10   c , respectively. To be more specific, the support portion  11   a  at the top is connected to the extension portion  10   a ; the support portion  11   b  protruding between the support portion  11   a  and the support portion  11   c  is connected to the extension portion  10   b ; and the support portion  11   c  at the bottom is connected to the extension portion  10   c . These support portions  11   a  to  11   c  are attached to the watch body  1  to rotate about a rotation center L as an axis extending orthogonal to the watch face  2 . The support portions  11   a  to  11   c  are rotated by a drive unit  13  provided in the watch body  1  according to the progression of time. 
     The pointers  3   a  to  3   c  include turning members  14   a  to  14   c  configured to turn the extension portions  10   a  to  10   c  to be raised to change the postures of the extension portions  10   a  to  10   c , respectively. These turning members  14   a  to  14   c  are disposed near the base ends of the extension portions  10   a  to  10   c.    
     As illustrated in  FIG. 3A , the turning member  14   a  is disposed near the base end of the extension portion  10   a  to turn the extension portion  10   a  to be raised from the upper surface  7  of the watch face  2 . The turning member  14   a  includes a turning shaft  15   a , an end portion  16   a , and an end portion  17   a . The turning shaft  15   a  serves as the axis of turning of the extension portion  10   a  and extends in a direction orthogonal to the extension portion  10   a.    
     The end portion  16   a  contacts the extension portion  10   a  in the vicinity of the base end of the extension portion  10   a  in order to maintain the posture of the extension portion  10   a  extending parallel to the watch face  2 . The end portion  16   a  is formed on the lower surface side of the extension portion  10   a . Meanwhile, as illustrated in  FIG. 3B , when the extension portions  10   a  is tuned 90 degrees, the end portion  17   a  abuts on the extension portion  10   a  in the vicinity of the base end of the extension portion  10   a  to maintain the posture of the extension portion  10   a . The end portion  17   a  is formed on the upper surface side of the extension portion  10   a . As described above, the extension portion  10   a  is turned about the turning shaft  15   a  in a direction approximately orthogonal to the watch face  2  to maintain the posture of the extension portion  10   a  by the end portion  17   a . Here, the configuration of the turning members  14   b  and  14   c  is approximately the same as that of the turning member  14   a.    
     Here, as illustrated in  FIG. 2 , the turning members  14   a  to  14   c  are located inside the opening  12  in a direction along the watch face  2 . Therefore, when the extension portions  10   a  to  10   c  are raised by the turning members  14   a  to  14   c  and therefore are orthogonal to the upper surface  7  of the watch face  2 , the extension portions  10   a  to  10   c  are located within the opening  12  in the direction along the watch face  2 . That is, the extension portions  10   a  to  10   c  are raised to extend in the opening direction of the opening  12 . Then, the opening  12  is moved along the extension portions  10   a  to  10   c  raised by the turning members  14   a  to  14   c , so that the watch face  2  is removed from the watch body  1 . 
     Next, the operation according to Embodiment 1 will be described. First, as illustrated in  FIG. 1 , the watch face  2  on which the decoration  8  is displayed is attached to the watch body  1 . In this case, as illustrated in  FIG. 2 , the pointers  3   a  to  3   c  are rotated on the upper surface  7  of the watch face  2  by the drive unit  13  to indicate the time displayed on the watch face  2 . 
     Next, the drive unit  13  is stopped by pushing, for example, a stop switch (not shown) to stop the rotation of the pointers  3   a  to  3   c . Then, the protection member  4  covering the pointers  3   a  to  3   c  is pushed up by the hand to separate the protection member  4  from the watch body  1 , and opened by the rotation of the open and close member  9  to a position where the protection member  4  does not overlap the watch face  2 . 
     When the protection member  4  is opened, the front ends of the pointers  3   a  to  3   c  are pushed up by the hand such that the pointers  3   a  to  3   c  are apart from the watch face  2 . Then, the extension portions  10   a  to  10   c  of the pointers  3   a  to  3   c  are turned by the turning members  14   a  to  14   c  to change the postures of the extension portions  10   a  to  10   c  such that the extension portions  10   a  to  10   c  are approximately orthogonal to the upper surface  7  of the watch face  2 , as illustrated in  FIGS. 3A and 3B . In this case, the end portions  17   a  to  17   c  of the turning members  14   a  to  14   c  abut on the extension portions  10   a  to  10   c  in the vicinity of the base ends of the extension portions  10   a  to  10   c , and therefore it is possible to easily raise the extension portions  10   a  to  10   c  such that the extension portions  10   a  to  10   c  are approximately orthogonal to the watch face  2 . In addition, the configuration of the turning members  14   a  to  14   c  is simple where the turning members  14   a  to  14   c  turn about the turning shafts  15   a  to  15   c , and therefore it possible to easily provide the turning member  14   a  to  14   c  for the extension portions  10   a  to  10   c.    
     Here, as illustrated in  FIG. 2 , the turning members  14   a  to  14   c  are disposed in different positions in a direction along the watch face  2 . To be more specific, the farther the turning members  14   a  to  14   c  are located from the watch face  2  in a direction orthogonal to the watch face  2 , the closer the turning members  14   a    14   c  are disposed to the rotation center L of the pointers  3   a  to  3   c . By this means, the turning positions of the extension portions  10   a  to  10   c  are different in the direction along the watch face  2 . Therefore, even though the extension portions  10   a  to  10   c  are turned to overlap with each other in the direction orthogonal to the watch face  2 , it is possible to raise the extension portions  10   a  to  10   c  without touching each other. 
     Moreover, the extension portions  10   a  to  10   c  are moved to overlap with each other, and therefore it is possible to turn the extension portions  10   a  to  10   c  by the turning members  14   a  to  14   c  at a time. For example, an alignment switch is connected to the drive unit  13  and pushed to automatically rotate the pointers  3   a  to  3   c  to point the same position in the watch face  2 , so that the extension portions  10   a  to  10   c  can be moved to overlap with each other. In this case, it is preferred that a raising member is stored in the watch body  1  to collectively raise the extension portions  10   a  to  10   c  which have been moved to overlap with each other. This raising member is stored in the edge of the watch face  2  to easily take the raising member out of the edge. Therefore, it is possible to easily raise the extension portions  10   a  to  10   c . For example, the raising member may be formed in a hook shape, so that it is possible to pull up the extension portions  10   a  to  10   c  from below. 
     Here, it is preferred that the turning members  14   a  to  14   c  are spaced from each other at a distance which is approximately the same as the thickness of each of the extension portions  10   a  to  10   c  in the direction along the watch face  2 . By this means, the turning members  14   a  to  14   c  are close to each other in the direction along the watch face  2 , and therefore it is possible to reduce the size of the opening  12  of the watch face  2  depending on the arrangement of the turning members  14   a  to  14   c.    
     Moreover, it is preferred the turning members  14   a  to  14   c  turn the extension portions  10   a  to  10   c  around the opening  12  of the watch face  2  at different positions to change the postures of the pointers  3   a  to  3   c . For example, as illustrated in  FIG. 4A , the extension portions  10   a  to  10   c  are rotated around the opening  12  of the watch face  2  to move to positions Pa to Pc with an angle of 90 degrees from each other, and then the turning members  14   a  to  14   c  may turn the extension portions  10   a  to  10   c . By this means, it is possible to smoothly raise the extension portions  10   a  to  10   c  without touching each other. Moreover, it is possible to prevent the extension portions  10   a  to  10   c  from touching each other, and therefore to dispose the turning members  14   a  to  14   c  at the same position in the direction along the watch face  2 . Consequently, it is possible to further reduce the size of the opening  12  of the watch face  2 . Here, it is preferred that the pointers  3   a  to  3   c  are automatically rotated to different positions around the opening  12  of the watch face  2  by pushing a movement switch (not shown). As described above, the pointers  3   a  to  3   c  are automatically moved, and therefore it is possible to easily raise the extension portions  10   a  to  10   c.    
     In this way, the extension portions  10   a  to  10   c  are raised to be orthogonal to the upper surface  7  of the watch face  2 , that is, raised not to face the upper surface  7 . Therefore, it is possible to change the postures of the extension portions  10   a  to  10   c  to extend within the opening  12  in the opening direction of the opening  12 . By this means, it is possible to smoothly move the watch face  2  along the extension portions  10   a  to  10   c  via the opening  12 , and therefore to easily remove the watch face  2  from the watch body  1  without removing the pointers  3   a  to  3   c  from the watch body  1 , as illustrated in  FIG. 4B . 
     Next, as illustrated in  FIG. 4C , the extension portions  10   a  to  10   c  are inserted into the opening  12  of a new watch face  18 , so that it is possible to attach the watch face  18  to the watch body  1 . In this way, it is possible to easily replace the watch face  2  with the watch face  18 . For example, it is possible to replace the watch face  2  on which the decoration  8  is displayed with the watch face  18  on which a decoration  19  different from the decoration  8  is displayed. Conventionally, it is difficult to remove the watch face  2  from the watch body  1 , and therefore it would be necessary to purchase a new watch to change the decoration  8  of the watch face  2 . However, with the present embodiment, it is possible to easily change the watch face  2 , and therefore to replace the decoration  8  with the decoration  19  only by replacing the watch face  2  with the watch face  18 . In addition, the watch face  18  can display various types of the decoration  19 , for example, which is designed by the owner or created by an artist. Moreover, the watch face  18  can display the decoration  19  corresponding to a song sung by a singer. For example, the watch face  18  may display the decoration  19  corresponding to the music inputted to an information input unit (not shown) of the watch body  1 , or corresponding to the design of a music media such as a CD (compact disk). 
     In this way, the watch face  18  on which the decoration  19  is displayed is attached to the watch body  1 , and then the extension portions  10   a  to  10   c  are turned by the turning members  14   a  to  14   c , and returned in the original postures parallel to the watch face  18 . At this time, the end portions  16   a  to  16   c  abut on the extension portions  10   a  to  10   c  in the vicinity of the base ends of the extension portions  10   a  to  10   c , and therefore it is possible to make it easy to return the extension portions  10   a  to  10   c  in the original postures. Then, the stop switch (not shown) is released to drive the drive unit  13 , so that the rotation of the pointers  3   a  to  3   c  is resumed at the right time. 
     With the present embodiment, the pointers  3   a  to  3   c  include the turning members  14   a  to  14   c  to change the postures of the extension portions  10   a  to  10   c  to be raised. Therefore, it is possible to remove the watch face  2  from the watch body  1  along the extension portions  10   a  to  10   c  raised by the turning members  14   a  to  14   c . Accordingly, there is no need to unnecessarily change the shape of the watch face  2  to remove the watch face  2  from the watch body  1 . Consequently, it is possible to easily remove the watch face  2  while maintaining the function of the watch face  2  such as the legibility of the time, and the design. 
     Embodiment 2 
     With the above-described Embodiment 1, it is preferred that the watch face  2 ,  18  has a fixing portion to fix the watch face  2 ,  18  to the watch body  1 . For example, as illustrated in  FIG. 5 , the watch face  18  according to Embodiment 1 may include fixing portions  21 . Meanwhile, concave portions  22  corresponding to the fixing portions  21  are formed in the watch body  1 . The two fixing portions  21  are formed to face one another in the vicinity of the edge of the watch face  18  and protrude from a lower surface  23  of the watch face  23 . 
     Here, the fixing portions  21  are provided such that the time displayed on the watch face  18  is located at a predetermined position of the watch body  1  when the fixing portions  21  are fitted in the concave portions  22 . Therefore, by fitting the fixing portions  21  in the concave portions  22 , it is possible to align the watch face  18  with the watch body  1 . With the present embodiment, the watch face  18  includes the fixing portions  21  to fix the watch face  18  to the watch body  1 , and therefore it is possible to easily align the watch face  18  with the watch body  1 . 
     Embodiment 3 
     With the above-described Embodiment 1 and 2, it is preferred that the watch body  1  includes an ejector to lift the watch face  2 ,  18  to separate from the watch body  1 . For example, as illustrated in  FIG. 6A , the watch body  1  according to Embodiment 1 may include an ejector  31 . This ejector  31  includes a lift part  32 , a lock part  33  and a release switch  34 . 
     The lift part  32  is configured to lift the watch face  2  in a direction in which the watch face  2  separates from the watch body  1 , and includes a lift body  35  and a biasing member  36 . The lift body  35  has a pillar shape extending in the watch body  1  in a direction orthogonal to the watch face  2 . The front end of the lift body  35  contacts the lower surface  23  of the watch face  2 . The lift body  35  includes a protrusion  37  protruding from the side surface of the lift body  35 . The lock part  33  engages with the upper surface of the protrusion  37  of the lift body  35  to lock the lift part  32 . The lock part  33  protrudes from the side wall of the storage part  38  in which the lift body  35  is stored. In addition, the lock part  33  protruding from the side wall of the storage part  38  can retract into the storage part  38 . When the lock part  33  retracts into the storage part  38 , it is possible to release the lock on the lift part  32 . The release switch  34  is connected to the lock part  33  to allow the lock part  33  to retract into the storage part  38 . 
     In this way, the lift part  32  locked by the lock part  33  is stored in the storage part  38 , and therefore does not lift the watch face  2 . Accordingly, the watch body  2  remains to be attached to the watch body  1 . Then, to remove the watch face  2  from the watch body  1 , the release switch  34  is pushed to allow the lock part  33  to retract into the storage part  38 . By this means, the lock on the lift body  35  by the lock part  33  is released. Then, as illustrated in  FIG. 6B , the lift body  35  biased by the biasing member  36  is raised to separate the watch face  2  from the watch body  1 . In this way, the watch face  2  is separated from the watch body  1 , and therefore it is possible to smoothly insert the fingers between the watch face  2  and the watch body  1 . By this means, it is possible to easily remove the watch face  2  from the watch body  1  along the extension portions  10   a  to  10   c  raised by the turning members  14   a  to  14   c . Here, the lock part  33  is biased to protrude from the side wall of the storage part  38 , and the protrusion  37  of the lift body  35  is moved from the front of the lock part  33 , so that the lock part  33  is moved to protrude from the side wall of the storage part  38 . 
     With the present embodiment, the watch body  1  includes the ejector  31  that lifts the watch face  2  to separate the watch face  2  from the watch body  1 , and therefore it is possible to easily remove the watch face  2  from the watch body  1 . 
     Embodiment 4 
     With the above-described Embodiments 1 to 3, it is preferred that the turning members  14   a  to  14   c  include assisting parts to bias the extension portions  10   a  to  10   c  in the turning direction to assist the extension portions  10   a  to  10   c  to change their postures, respectively. For example, as illustrated in  FIG. 7 , the turning member  14   a  according to Embodiment 1 may have an assisting part  41   a . This assisting part  41   a  is provided on the upper surface of the extension portion  10   a  to bias the extension portion  10   a  to the base end side to assist the extension portion  10   a  to be raised. 
     By this means, the extension portion  10   a  is biased by the assisting part  41   a , and therefore it is possible to automatically raise the extension portion  10   a  by lightly touching the extension portion  10   a , and therefore to easily change the posture of the extension portion  10   a . Moreover, it is possible to reduce the pressure applied to the extension portion  10   a  when the extension portion  10   a  is raised, and therefore to prevent the extension portion  10   a  from deforming. Here, each of the turning members  14   b  and  14   c  includes an assisting part which is the same as that of the turning member  14   a.    
     With the present embodiment, the turning members  14   a  to  14   c  include the assisting parts  41   a  to  41   c  that bias the extension portions  10   a  to  10   c  in the turning direction to assist the extension portions  10   a  to  10   c  to change their postures. Therefore, it is possible to easily change the postures of the extension portions  10   a  to  10   c . Moreover, the extension portions  10   a  to  10   c  may be automatically turned by the turning members  14   a  to  14   c  without touching the extension portions  10   a  to  10   c  by the hand. 
     Embodiment 5 
     With the above-described Embodiments 1 to 4, it is preferred that the watch body  1  includes a correction unit to correct the differences in the positions of the pointers  3   a  to  3   c . For example, as illustrated in  FIG. 8 , the watch body  1  according to Embodiment 1 may include a correction unit  51  connected to the drive unit  13 . This correction unit  51  includes a receiver that receives a standard time signal transmitted from a standard wave transmitting station. The correction unit  51  calculates the differences in the pointers  31  to  3   c  from the standard time, based on the standard time received by the receiver and the positions of the pointers  3   a  to  3   c . The calculated differences are outputted from the correction unit  51  to the drive unit  13 . 
     Then, the drive unit  13  corrects the positions of the pointers  3   a  to  3   c , based on the differences inputted from the correction unit  51 . By this means, even though the positions of the pointers  3   a  to  3   c  are different from the standard time due to, for example, the turning of the extension portions  10   a  to  10   c , the correction unit  51  corrects the differences, and therefore the pointers  3   a  to  3   c  can indicate the correct time. 
     With the present embodiment, the watch body  1  includes the correction unit  51  to correct the differences in the positions of the pointers  31  to  3   c , and therefore the pointers  3   a  to  3   c  can indicate the correct time. 
     With the above-described Embodiments 1 to 5, the extension portions  10   a  to  10   c  are formed to extend parallel to the upper surface  7  of the watch face  2  from the opening  12  to the edge of the watch face  2 . However, the extension portions  10   a  to  10   c  may not necessarily extend parallel to the upper surface  7  of the watch face  2  as long as the extension portions  10   a  to  10   c  extend to face the upper surface  7  from the opening  12 . For example, the extension portions  10   a  to  10   c  may be formed to extend at an angle with the upper surface  7  of the watch face  2 . 
     In addition, with the above-described Embodiments 1 to 5, the turning members  14   a  to  14   c  turn the extension portions  10   a  to  10   c  in the direction approximately orthogonal to the watch face  2 . However, this is by no means limiting as long as the turning members  14   a  to  14   c  turn the extension portions  10   a  to  10   c  to be raised. Moreover, with the above-described Embodiments 1 to 5, the turning members  14   a  to  14   c  turn the extension portions  10   a  to  10   c  for the same angle with respect to the watch face  2 . However, this is by no means limiting as long as the turning members  14   a  to  14   c  turn the extension portions  10   a  to  10   c  to be raised. For example, the turning members  14   a  to  14   c  can change the angle of the turning of the extension portions  10   a  to  10   c  depending on the lengths of the extension portions  10   a  to  10   c . That is, the extension portion  10   a  longer than the extension portion  10   b  is turned for an angle greater than that of the extension portion  10   b . By this means, it is possible to arrange the extension portions  10   a  to  10   c  at the same distance from the center of the opening  12  when the extension portions  10   a  to  10   c  are raised, and therefore to reduce the size of the opening  12  of the watch face  2 . 
     Moreover, with the above-described Embodiments 1 to 5, the turning members  14   a  to  14   c  turn the extension portions  10   a  to  10   c  to be raised. However, this is by no means limiting as long as it is possible to change the postures of the extension portions  10   a  to  10   c  to be raised. For example, as illustrated in  FIG. 9 , a change portion  61   a  may be provided instead of the turning member  14   a  according to Embodiment 1. This change portion  61   a  is formed as a concave portion on the upper surface of the extension portion  10   a  to fold the extension portion  10   a  to be raised in order to change the posture of the extension portion  10   a . Here, in order to form this change portion, the extension portions  10   a  to  10   c  may be made of a flexible material, and therefore it is possible to fold the extension portions  10   a  to  10   c  to be raised, and consequently to change the postures of the extension portions  10   a  to  10   c . In this case, it is preferred that the change portions are made of a shape-memory material. 
     Moreover, with the above-described Embodiments 1 to 5, the watch face  2 ,  18  may be made of an elastic material, such as rubber and silicone. Likewise, the time and the decoration displayed on the watch face  2 ,  18  may be made of an elastic material. By this means, it is possible to deform the opening  12  of the watch face  12 ,  18 . Even when the size of the opening  12  is reduced, it is possible to smoothly move the watch face  2 ,  18  along the extension portions  10   a  to  10   c . For example, when the turning members  14   a  to  14   c  are disposed outside the opening  12  in the direction along the watch face  2 , that is, when a circumference formed by the front ends of the extension portions  10   a  to  10   c  raised by the turning members  14   a  to  14   c  is greater than the opening  12 , it is possible to remove the watch face  2  along the extension portions  10   a  to  10   c  by deforming the opening  12 . 
     Furthermore, with the above-described Embodiments 1 to 5, it is possible to stereoscopically display the time and the decoration on the watch face  12 ,  18 . For example, the decoration  8  of the watch face  2  may be popped up when the protection member  4  opens. Alternatively, the decoration  8  of the watch face  2  may be formed to move in three dimensions. Furthermore, with the above-described Embodiments 1 to 5, the watch face  2 ,  18  has a discoid shape. However, this is by no means limiting as long as the watch face  2 ,  18  has the opening  12 . 
     Furthermore, with the above-described Embodiments 1 to 5, the pointers  3   a  to  3   c  are rotated according to the time. However, this is by no means limiting as long as the pointers  3   a  to  3   c  extend to face the upper surface  7  of the watch face  2 . For example, when the decoration  8  is moved on the watch face  2 , the pointers  3   a  to  3   c  may be rotated depending on the motion of the decoration  8 . Alternatively, the pointers  3   a  to  3   c  may be rotated counterclockwise with respect to the time displayed on the watch face  2 . 
     Furthermore, with the above-described Embodiments 1 to 5, the watch has the three pointers  3   a  to  3   c . However, this is by no means limiting, and the watch may have one pointer. Furthermore, with the above-described Embodiments 1 to 5, the watch is a wristwatch. However, this is by no means limiting as long as the pointers  3   a  to  3   c  are arranged to sandwich the watch face  2  between the pointers  3   a  to  3   c  and the watch body  1 . For example, the present invention is applicable to, for example, a wall clock, a table clock, a pocket watch, and an alarm clock.
