Description

The present invention relates to a camera device, and more particularly to a camera device capable of extending a lens barrel forward along an optical axis direction.

Conventionally, a camera having a lens barrel feeding mechanism for feeding a lens barrel forward along the optical axis direction has been known (see, for example, Patent Document 1). In order to reduce the thickness of a camera provided with such a lens barrel feeding mechanism, it is also considered to have a multi-stage lens barrel and a nested structure. However, there is a problem that it is difficult to reduce the thickness of the camera because the mechanism for extending the lens barrel having such a nested structure forward in multiple stages tends to be complicated and requires a large storage space.

Japanese Unexamined Patent Publication No. 2014-56009

The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a compact camera device capable of extending a lens barrel having a nested structure in multiple stages.

According to one aspect of the present invention, there is provided a compact camera device capable of extending a lens barrel having a nested structure in multiple stages. This camera device includes a barrel portion and a lens barrel housed inside the barrel portion and movable in a feeding direction along an optical axis direction from a retracted state. The lens barrel is a first lens barrel unit that can move in the feeding direction with respect to the barrel portion from a state of being housed inside the barrel portion in the radial direction, and a radial direction of the first lens barrel unit. It includes a second lens barrel unit that can move in the feeding direction with respect to the first lens barrel unit from the state of being housed inside. The second lens barrel unit has an engaging portion provided on the first lens barrel unit side. The first lens barrel unit is provided on the base portion, the base portion, and rotates to the base portion, the lens barrel unit urging portion that urges the second lens barrel unit toward the feeding direction, and the base portion. It has an operating lever rotatably provided about a shaft. The operating lever has an operating portion that protrudes outward in the radial direction of the base portion and a locking portion that engages with the engaging portion of the second lens barrel unit by rotating in the locking direction about the rotation axis. And have. The first lens barrel unit has a lever urging portion that urges the operating lever toward the locking direction. When the first barrel unit moves with respect to the barrel portion in the feeding direction, the barrel portion comes into contact with the operating portion of the operating lever, and the operating lever is moved in the direction opposite to the locking direction. It has a first contact portion to be rotated.

According to such a configuration, when the lens barrel is in the retracted state, the locking portion of the operating lever is engaged with the engaging portion of the second lens barrel unit by the lever urging portion of the first lens barrel unit. Therefore, the first lens barrel unit and the second lens barrel unit move in the feeding direction as a unit, but while the lens barrel is being pulled out from the retracted state, the operating part of the operating lever is the first barrel part. By abutting on the abutting portion of No. 1, the operating lever rotates in the direction opposite to the locking direction, and the locking portion of the operating lever and the engaging portion of the second lens barrel unit are disengaged. Since the second lens barrel unit is urged in the feeding direction by the lens barrel unit urging portion of the first lens barrel unit, the locking portion of the operating lever and the engaging portion of the second lens barrel unit When the engagement with the lens barrel unit is disengaged, the second lens barrel unit moves in the feeding direction with respect to the first lens barrel unit. As described above, according to the configuration according to the present invention, the lens barrel having a nested structure can be extended in the feeding direction in two stages due to the simple and compact structure, and the camera device can be further thinned. ..

The lens barrel may have a movement restricting unit that regulates the movement of the second lens barrel unit in the feeding direction with respect to the first lens barrel unit within a certain range. The first lens barrel unit may have a rotation regulating unit that regulates the rotation of the operating lever in the locking direction. Further, the lock portion of the operating lever may have an inclined surface capable of guiding the engaging portion of the second lens barrel unit. Further, the engaging portion of the second lens barrel unit may have an inclined surface capable of guiding the locking portion of the operating lever. Further, it is preferable that the lock portion of the operating lever has a folded shape that can be elastically deformed.

The operating portion of the operating lever may protrude outward in the radial direction from the groove portion formed in the barrel portion. In this case, the first contact portion may be composed of an edge portion of the groove portion extending in a direction perpendicular to the feeding direction.

In the barrel portion, when the operating portion of the operating lever is separated from the first contact portion of the barrel portion, the operating lever does not rotate in the locking direction due to the urging force of the lever urging portion. It is preferable to have a second contact portion that comes into contact with the actuating portion of the actuating lever and rotates the actuating lever in the locking direction. In this case, the operating portion of the operating lever projects radially outward from the groove through the groove formed in the barrel portion, and the second contact portion extends obliquely with respect to the feeding direction. It may be composed of the edge portion of the groove portion.

According to the present invention, when the lens barrel is in the retracted state, the locking portion of the operating lever is engaged with the engaging portion of the second lens barrel unit by the lever urging portion of the first lens barrel unit. Therefore, the first lens barrel unit and the second lens barrel unit move in the feeding direction as a unit, but while the lens barrel is being pulled out from the retracted state, the operating portion of the operating lever is the first barrel portion. By abutting on the abutting portion, the operating lever rotates in the direction opposite to the locking direction, and the locking portion of the operating lever and the engaging portion of the second lens barrel unit are disengaged. Since the second lens barrel unit is urged in the feeding direction by the lens barrel unit urging portion of the first lens barrel unit, the locking portion of the operating lever and the engaging portion of the second lens barrel unit When the engagement with the lens barrel unit is disengaged, the second lens barrel unit moves in the feeding direction with respect to the first lens barrel unit. As described above, according to the configuration according to the present invention, the lens barrel having a nested structure can be extended in the feeding direction in two stages due to the simple and compact structure, and the camera device can be further thinned. ..

As shown in FIG. 3, two engaging projections 14 projecting outward in the radial direction are formed at the rear end of the first tubular portion 11 of the lens barrel 10. As shown in FIG. 2, two guide grooves 24 extending along the direction of the optical axis P (X direction) are formed in the barrel portion 22 of the frame 20 corresponding to the respective engaging protrusions 14. .. Each of the engaging protrusions 14 of the lens barrel 10 is housed inside the guide groove 24 of the barrel portion 22 and engages with the guide groove 24. The width of the guide groove 24 in the Z direction is slightly larger than the width of the engaging projection 14 in the Z direction. Therefore, the engaging projection 14 is guided by the guide groove 24 and moves in the direction of the optical axis P (X direction) inside the guide groove 24.

As shown in FIG. 2, an operation button 8 is provided in the vicinity of the barrel portion 22 of the frame 20 in a state of being urged in the + X direction by the coil spring 8A.

The lens barrel 10 is extended in the + X direction (feeding direction). When the lens barrel 10 protrudes from the barrel portion 22 in the + X direction in this way, the power of the camera device 1 is turned on by a switch mechanism (not shown).

The lens barrel feeding mechanism 9 includes a lever 9A that pushes the engaging protrusion 14 in the + X direction in conjunction with the operation button 8 and a torsion coil spring in which the direction in which the engaging protrusion 14 is urged is reversed depending on the position of the engaging protrusion 14 (FIG. (Not shown) and is included. When the engaging projection 14 moves in the + X direction beyond a predetermined position, the torsion coil spring urges the engaging projection 14 in the + X direction, and conversely, the engaging projection 14 exceeds the predetermined position and -X. When moving in the direction, the engaging projection 14 is configured to be urged in the −X direction. The lens barrel feeding mechanism 9 is not limited to a specific one, and may have any structure as long as the lens barrel 10 can be fed in the + X direction.

In the present embodiment, while the lens barrel 10 is moving in the + X direction with respect to the barrel portion 22, the front lens barrel unit 32 moves in the + X direction with respect to the rear lens barrel unit 31 as shown in FIG. It is designed to (feed out). In the present embodiment, in the state shown in FIG. 4, the user can manually pull out the third tubular portion 13 from the second tubular portion 12 in the + X direction. FIG. 1 shows a state in which the lens barrel 10 is housed in the barrel portion 22 of the frame 20, and in this state, the lens barrel 10 is the shortest in the X direction. Hereinafter, this state will be referred to as a “collapsed state”.

FIG. 5 is an exploded perspective view of the lens barrel 10. FIG. 6 is a schematic conceptual diagram showing the interrelationship of the components of the lens barrel 10 in the retracted state, and the components are simplified and schematically shown for easy understanding. In FIG. 6, the second tubular portion 12 and the third tubular portion 13 are shown as the front lens barrel unit 32 without distinguishing them from each other.

As shown in FIG. 5, the second tubular portion 12 of the front lens barrel unit 32 has a cylindrical portion 71 and three protrusions 72 protruding radially outward from the end portion of the cylindrical portion 71 on the −X direction side. Includes. Further, the third tubular portion 13 of the front lens barrel unit 32 has a cylindrical portion 61 housed inside the cylindrical portion 71 of the second tubular portion 12 and a flange portion extending outward in the radial direction at the front end of the cylindrical portion 61. It includes 62 and a base portion 63 having a rectangular opening S1 formed in the center. Two engaging portions 64 extending in the −X direction are formed on the rear lens barrel unit 31 side of the base portion 63. Each engaging portion 64 has a triangular columnar claw portion 65 at the tip end portion.

The rear lens barrel unit 31 includes a base portion 40 having a rectangular opening S2 formed in the center, and a cylindrical portion 41 extending from the base portion 40 in the + X direction. The engaging projection 14 described above extends radially outward from the base portion 40. On the inner peripheral surface of the cylindrical portion 41, three guide grooves 45 extending in the X direction corresponding to the three protrusions 72 of the front lens barrel unit 32 are formed. Each protrusion 72 of the front lens barrel unit 32 is housed inside the guide groove 45 of the cylindrical portion 41 of the rear lens barrel unit 31 and engages with the guide groove 45. The width of the guide groove 45 in the circumferential direction is slightly larger than the width of the protrusion 72 in the circumferential direction. Therefore, the protrusion 72 moves in the X direction inside the guide groove 45 while being guided by the guide groove 45.

FIG. 7 is an exploded perspective view of the rear lens barrel unit 31 of the lens barrel 10. As shown in FIG. 7, the rear lens barrel unit 31 includes two actuating levers 42 attached to the base 40 and two extrusion levers 43 attached to the base 40. The two actuating levers 42 are arranged at positions symmetrical with respect to the center of the base portion 40, and the extrusion lever 43 is also arranged at a position symmetrical with respect to the center of the base portion 40.

FIG. 8 is a perspective view showing the operating lever 42. As shown in FIG. 8, the operating lever 42 is attached to the shaft portion 46 (see FIG. 7) of the base portion 40, and is configured to be rotatable around the shaft portion 46. The actuating lever 42 includes a base 51 having a shaft hole 50 into which the shaft portion 46 of the base portion 40 is inserted, an actuating portion 52 extending in the + Z direction from the base 51, and a lock formed on the + X direction side of the base 51. It has a portion 53 and a spring receiving portion 54 extending in the + Z direction from the root portion of the lock portion 53. The length of the operating portion 52 in the Z direction is such that when the operating lever 42 is attached to the base portion 40, the operating portion 52 protrudes outward in the radial direction from the base portion 40 as shown in FIG. ing.

As shown in FIGS. 6 and 7, one arm portion 55A of the torsion coil spring 55 is engaged with the spring receiving portion 54 of the operating lever 42. The coil portion 55B of the torsion coil spring 55 is arranged around the shaft portion 46 of the base portion 40, and the other arm portion 55C is engaged with the wall portion 40A of the base portion 40. The torsion coil spring 55 is mounted so that the opening angle between the arms 55A and 55C is smaller than the free angle of the torsion coil spring 55. Therefore, the operating lever 42 is in a state of being urged in the counterclockwise direction about the rotation axis J shown in FIG. In the following, the direction in which the operating lever 42 is urged by the torsion coil spring 55, that is, the counterclockwise direction with respect to the rotation axis J in FIG. 8 is referred to as the “locking direction”, and the clockwise direction with respect to the rotation axis J. Is referred to as the "unlocking direction". As described above, the torsion coil spring 55 in the present embodiment functions as a lever urging portion that urges the operating lever 42 in the locking direction.

As shown in FIG. 8, the lock portion 53 of the operating lever 42 extends from the base portion 51 in the + X direction, and then folds back in the −X direction and extends. Due to such a folded shape, the lock portion 53 is elastically deformed in the Y direction. The lock portion 53 has a triangular columnar claw portion 56 at the tip end portion. As shown in FIG. 6, in the retracted state, the claw portion 56 of the lock portion 53 of the operating lever 42 is engaged with the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32.

As described above, the actuating portion 52 of the actuating lever 42 projects radially outward from the base portion 40, but as shown in FIG. 2, the barrel portion 22 corresponds to the actuating portion 52 of the actuating lever 42. Is formed with a groove 25 extending in the X direction. The operating portion 52 of the operating lever 42 passes through the groove portion 25 and projects outward from the groove portion 25 in the radial direction. When the lens barrel 10 extends in the + X direction, the operating portion 52 of the operating lever 42 moves inside the groove of the barrel portion 22.

FIG. 9 is a perspective view showing the extrusion lever 43. As shown in FIG. 9, the extrusion lever 43 includes a base 81 having a shaft hole 80 into which a shaft 47 (see FIG. 7) attached to the base 40 is inserted, and an arm extending from the base 81 in the + Z direction in general. It has a portion 82, a pusher portion 83 provided at the tip of the arm portion 82, and a spring receiving portion 84 formed on the arm portion 82.

As shown in FIGS. 6 and 7, one arm portion 85A of the torsion coil spring 85 is engaged with the spring receiving portion 84 of the extrusion lever 43. The coil portion 85B of the torsion coil spring 85 is arranged around the base portion 81 of the extrusion lever 43, and the other arm portion 85C is engaged with the surface of the base portion 40. The torsion coil spring 85 is mounted so that the opening angle between the arms 85A and 85C is smaller than the free angle of the torsion coil spring 85. Therefore, the extrusion lever 43 is in a state of being urged in the counterclockwise direction about the rotation axis K shown in FIG.

As shown in FIG. 6, the pusher portion 83 of the extrusion lever 43 urged by the torsion coil spring 85 is the rear end surface 32A of the front lens barrel unit 32 (for example, the rear end surface 12A of the second cylinder portion 12 shown in FIG. 5). The extrusion lever 43 pushes the front lens barrel unit 32 in the + X direction (feeding direction). That is, the extrusion lever 43 and the torsion coil spring 85 form a lens barrel unit urging portion that urges the front lens barrel unit 32 in the + X direction. In the retracted state shown in FIG. 6, as described above, the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32 and the claw portion 56 of the lock portion 53 of the rear lens barrel unit 31 are engaged with each other. Therefore, the front lens barrel unit 32 does not move in the + X direction with respect to the rear lens barrel unit 31.

10A to 10F are schematic conceptual diagrams for explaining the extension operation and the retracting operation of the lens barrel 10, and correspond to the schematic conceptual diagram of FIG. As described above, when the user pushes the operation button 8 in the −X direction, the lens barrel extension mechanism 9 attached to the barrel portion 22 pushes the engaging projection 14 of the lens barrel 10 in the + X direction, and the lens barrel. 10 moves in the + X direction. At this time, as described above, since the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32 and the claw portion 56 of the lock portion 53 of the operating lever 42 of the rear lens barrel unit 31 are engaged with each other. The front lens barrel unit 32 and the rear lens barrel unit 31 move together in the + X direction.

When the front lens barrel unit 32 and the rear lens barrel unit 31 move together in the + X direction, the operating portion 52 of the operating lever 42 of the rear lens barrel unit 31 moves in the groove portion 25 of the barrel portion 22 in the + X direction. However, as shown in FIG. 10A, it comes into contact with the edge portion 25A of the groove portion 25 of the barrel portion 22 extending in the direction perpendicular to the X direction. In this state, when the front lens barrel unit 32 and the rear lens barrel unit 31 move further in the + X direction, the operating portion 52 of the operating lever 42 is pushed in the −X direction by the edge portion 25A of the groove portion 25 of the barrel portion 22. Along with this, as shown by the arrow in FIG. 10A, the operating lever 42 rotates in the unlocking direction (clockwise in FIG. 10A) around the shaft portion 46 of the base portion 40 against the urging force of the torsion coil spring 55. To do.

When the operating lever 42 rotates in the unlocking direction in this way, the claw portion 56 of the locking portion 53 of the operating lever 42 is eventually disengaged from the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32. At this time, since the extrusion lever 43 of the rear lens barrel unit 31 pushes the rear end surface 32A of the front lens barrel unit 32 in the + X direction by the torsion coil spring 85, the locking portion 53 of the operating lever 42 and the front lens barrel unit 32 are engaged. When the engagement with the joint portion 64 is disengaged, the front lens barrel unit 32 is pushed out in the + X direction by the extrusion lever 43 as shown in FIG. 10B. As a result, the front lens barrel unit 32 is extended in the + X direction with respect to the rear lens barrel unit 31.

At this time, as shown in FIG. 10B, the protrusion 72 of the front lens barrel unit 32 abuts on the + X direction edge 45A of the guide groove 45 of the rear lens barrel unit 31, so that the rear lens barrel unit of the front lens barrel unit 32 Movement in the + X direction with respect to 31 is restricted. As described above, the guide groove 45 of the cylindrical portion 41 of the rear lens barrel unit 31 and the protrusion 72 of the front lens barrel unit 32 are movements that restrict the movement of the front lens barrel unit 32 with respect to the rear lens barrel unit 31 within a certain range. Functions as a regulatory department. Needless to say, a similar movement restricting portion may be formed by forming a protrusion on the rear lens barrel unit 31 and forming a guide groove on the front lens barrel unit 32.

As described above, the edge portion 25A of the groove portion 25 of the barrel portion 22 in the present embodiment comes into contact with the operating portion 52 of the operating lever 42 when the rear lens barrel unit 31 moves in the + X direction with respect to the barrel portion 22. It functions as a (first) contact portion that rotates the operating lever 42 in the unlocking direction. Such a contact portion is not limited to the edge portion 25A of the groove portion 25, and for example, the first contact portion can be formed by a wall formed inside the barrel portion 22.

On the other hand, as shown in FIG. 10B, in order to change the state in which the front lens barrel unit 32 and the rear lens barrel unit 31 are extended in the + X direction to the retracted state, the user can use, for example, the front lens barrel unit 32 (for example, a third lens barrel unit 32). The flange portion 62) of the tubular portion 13 is pushed in the −X direction. At this time, the user needs to push the front lens barrel unit 32 in the −X direction against the urging force of the torsion coil spring 85 urging the extrusion lever 43. When the front lens barrel unit 32 is pushed in the −X direction, as shown in FIG. 10C, the front lens barrel unit 32 first moves in the −X direction with respect to the rear lens barrel unit 31.

When the user further pushes the front lens barrel unit 32 in the −X direction from the state shown in FIG. 10C, the flange portion 62 of the third barrel portion 13 of the front lens barrel unit 32 becomes the cylinder portion 41 of the rear lens barrel unit 31. Since it comes into contact with the tip, the rear lens barrel unit 31 also moves in the −X direction together with the front lens barrel unit 32. Along with this, the operating portion 52 of the operating lever 42 separates from the edge portion 25A of the groove portion 25 of the barrel portion 22 as shown in FIG. 10D. As a result, the operating lever 42 is rotated in the locking direction by the urging of the torsion coil spring 55, and the claw portion 56 of the locking portion 53 engages with the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32. At this time, as shown in FIG. 10D, the actuating portion 52 of the actuating lever 42 abuts against the rear end surface 40B of the base portion 40, thereby restricting the rotation of the actuating lever 42 in the locking direction. As described above, in the present embodiment, the rear end surface 40B of the base portion 40 of the rear lens barrel unit 31 functions as a rotation regulating portion that regulates the rotation of the operating lever 42 in the locking direction.

When the user pushes the front lens barrel unit 32 and the rear lens barrel unit 31 in the −X direction by a certain distance or more, the lens barrel feeding mechanism 9 urges the engaging projection 14 of the rear lens barrel unit 31 as described above. Is reversed, and the engaging projection 14 of the rear lens barrel unit 31 is urged in the −X direction by the lens barrel feeding mechanism 9. Therefore, even if the user releases the front lens barrel unit 32, the rear lens barrel unit 31 continues to move in the −X direction. At this time, since the claw portion 56 of the lock portion 53 of the operating lever 42 of the rear lens barrel unit 31 and the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32 are engaged, the front lens barrel unit 32 also The lens barrel 10 moves in the −X direction together with the rear lens barrel unit 31, and the lens barrel 10 is in a retracted state as shown in FIG.

The description of the retracting operation described above is based on the premise that the front lens barrel unit 32 first moves in the −X direction, but when the rear lens barrel unit 31 first moves in the −X direction, FIG. 10E As shown in the above, since the operating portion 52 of the operating lever 42 is separated from the edge portion 25A of the groove portion 25 of the barrel portion 22, the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32 is the locking portion of the operating lever 42. Before moving to a position where it can engage with the claw portion 56 of 53, the operating lever 42 rotates in the locking direction due to the urging of the torsion coil spring 55. Even in such a case, according to the present embodiment, the lens barrel 10 can be in the retracted state.

That is, as shown in FIG. 10E, the triangular columnar claw portion 56 of the lock portion 53 of the operating lever 42 has an inclined surface 56A capable of guiding the claw portion 65 of the engaging portion 64 of the front lens barrel unit 32. There is. Further, the triangular columnar claw portion 65 of the engaging portion 64 of the front lens barrel unit 32 also has an inclined surface 65A capable of guiding the claw portion 56 of the lock portion 53 of the operating lever 42. Therefore, when the front lens barrel unit 32 is pushed in the −X direction in the state shown in FIG. 10E, the inclined surface 56A of the claw portion 56 of the lock portion 53 and the inclined surface 65A of the claw portion 65 of the engaging portion 64 are in sliding contact with each other. However, the lock portion 53 and the engaging portion 64 are elastically deformed to get over the claw portions 56 and 65 and engage with each other. In particular, in the present embodiment, since the lock portion 53 of the operating lever 42 has the folded shape as described above, it is easily elastically deformed, and the claw portion 56 of the lock portion 53 and the claw portion of the engaging portion 64 are easily deformed. It can be engaged with 65. When the claw portion 56 of the lock portion 53 and the claw portion 65 of the engaging portion 64 are engaged in this way, the state shown in FIG. 10D is obtained. Therefore, the lens barrel 10 is brought into the retracted state by the above-mentioned operation. Can be done.

Further, in the retracting operation described above, if the torsion coil spring 55 does not urge the operating lever 42 in the locking direction for some reason, the claw portion 56 of the locking portion 53 of the operating lever 42 and the claw portion of the engaging portion 64 It is also conceivable that the lens barrel 10 cannot be engaged with the 65 and the lens barrel 10 cannot be retracted. In the present embodiment, in order to deal with such a problem, as shown in FIG. 2, an edge portion 25B extending obliquely with respect to the X direction is formed in the groove portion 25 of the barrel portion 22 described above.

That is, when the user further pushes the front lens barrel unit 32 in the −X direction from the state shown in FIG. 10C and the urging force of the torsion coil spring 55 does not act on the operating lever 42, the operating lever 42 moves in the locking direction. It will move in the −X direction without rotating, but at that time, as shown in FIG. 10F, the edge 25B of the groove 25 of the barrel portion 22 comes into contact with the operating portion 52 of the operating lever 42. There is. Then, as the operating lever 42 moves in the −X direction, the operating portion 52 of the operating lever 42 is guided by the edge portion 25B of the groove portion 25, and the operating lever 42 rotates in the locking direction accordingly. There is. As a result, the claw portion 56 of the lock portion 53 and the claw portion 65 of the engaging portion 64 can be engaged with each other. As described above, the edge portion 25B of the groove portion 25 of the barrel portion 22 in the present embodiment functions as a (second) contact portion that abuts on the actuating portion 52 of the actuating lever 42 and rotates the actuating lever 42 in the locking direction. To do. Such a contact portion is not limited to the edge portion 25B of the groove portion 25, and for example, the second contact portion can be formed by a wall formed inside the barrel portion 22.

In the above example, the lock portion 53 of the operating lever 42 has a U-shaped folded shape, but such a folded shape is not always necessary. Therefore, for example, instead of the operating lever 42 described above, an operating lever 142 having a lock portion 153 extending from the base 51 without folding back can be used as shown in FIG. However, in order to facilitate elastic deformation of the lock portion when the collapsible operation is performed from the state shown in FIG. 10E, it is preferable to use the lock portion 53 having a U-shaped folded shape.

The terms "front", "front", "rear", "rear", "upper", "upper", "lower", "lower", and other terms used in the present specification to indicate the positional relationship are used. It is used in the context of the illustrated embodiment and varies with the relative positional relationship of the device.

Although the preferred embodiment of the present invention has been described so far, it goes without saying that the present invention is not limited to the above-described embodiment and may be implemented in various different forms within the scope of the technical idea.
