Therefore, the driven member always moves integrally with the carriage in the same posture.

JP 2009-127742 A

  However, in the driving device described in Patent Literature 1, when it is necessary to switch the posture of the driven member, it is necessary to provide another driving source such as a motor or a tilt mechanism on the carriage. For this reason, the configuration is complicated, and the carriage is increased in size and weight.

  In view of the above problems, an object of the present invention is to provide a composite drive device that can perform linear drive of a driven member and tilt drive of a driven member with a simple configuration.

In order to solve the above problems, a composite drive device according to the present invention includes a drive source, a linear drive mechanism that directly moves a driven member to one side and the other side in a first direction by a driving force of the drive source, A tilt drive mechanism for inclining a distal end side of the driven member to one side or the other side in a second direction intersecting with the first direction with movement of the driven member to one side in the first direction; , have a, the linear drive mechanism, according to the above when moving in the first direction has a guide member for regulating the orientation of the driven member, wherein the tilt drive mechanism, the driven portion is the guide member It is characterized in that it has a contact portion that makes contact with the driven member on one side or the other side in the second direction and tilts the driven member when moved to a position where the restriction on the posture is released .

In the present invention, the driven member and the contact portion are brought into contact with each other by the linear motion of the driven member by the linear drive mechanism, and the tip end side of the driven member is inclined in the second direction. Therefore, with a simple configuration using one driving source, linear driving of the driven member and tilt driving of the driven member can be performed. In addition, when the driven member is tilted, if the distance over which the driven member moves linearly is long, the posture of the driven member can be adjusted, for example, the driven member can be largely tilted. Further, according to such a configuration, even when the posture of the driven member is regulated by the guide member, the tip end side of the driven member can be inclined.

In the present invention, the linear drive mechanism supports a feed screw rotating around an axis extending in the first direction and a driven member swingably in the second direction by a driving force of the drive source. In this state, a first carriage that is directly moved to one side and the other side in the first direction by the feed screw can be adopted.

And a biasing member. According to this configuration, the driven member can be brought into contact with the contact portion by the linear motion of the driven member.

In the present invention, the linear drive mechanism has a switching mechanism for switching mechanical connection between the driven member and the first carriage, and the urging member is provided on the second carriage side. The switching mechanism is configured such that when the first carriage starts moving to one side in the first direction, a mechanical connection between the driven member and the first carriage is released, and It is preferable that the driven member and the first carriage are mechanically connected to each other after the first carriage has moved a predetermined distance to one side in the first direction. According to this configuration, even when the first carriage starts moving, the switching mechanism is in the released state in which the mechanical connection between the driven member and the first carriage is released. Does not move to one side in the first direction. Further, if the first carriage moves a predetermined distance to one side in the first direction and the switching mechanism is brought into a connected state in which the driven member and the first carriage are mechanically connected, the driven member becomes: It moves to one side in the first direction together with the first carriage. Therefore, the timing at which the driven member moves linearly can be set appropriately.

(Opening / closing operation)
FIG. 7 is an explanatory diagram showing the operation of the opening / closing mechanism 6 of the combined drive device 1 to which the present invention is applied. In FIG. 7, the position of the opening and closing member 4 and the like in the closed state is indicated by a solid line, and the position of the opening and closing member 4 and the like in the open state is indicated by a dashed line.

As shown in FIG. 7, in a closed state in which the opening 20 of the frame 2 is closed by the opening / closing member 4, the arm-shaped rotating member 66 is in a state of standing up toward one side Y <b> 1 in the first direction Y. In this state, in the opening / closing member 4, the first member 41 is in a state of being aligned with the second member 42 on the other side Z2 in the second direction Z. In the closed state, the pinion 62 is located at the second portion 613b of the first slit 613. Further, the pinion 62 is configured to move the first member 41 in the second direction Z.
And the second member 42. Therefore, in the step portion 412 of the first rack 410, a portion formed at an end portion facing one side Z1 in the second direction Z engages with the pinion 62 from the other side Z2 in the second direction Z, and the second rack Of the step 420, in the step 422, a portion formed at the end facing the other side Z <b> 2 in the second direction Z is engaged with the pinion 62 from one side Z <b> 1 in the second direction Z.

  When the motor 50 rotates in one direction from this state, the rotational driving force of the motor 50 is transmitted to the rotating member 66 via the transmission mechanism 67 (the gear transmission mechanism 68 and the belt transmission mechanism 69) shown in FIG.

Rotate. Therefore, the shaft 442 of the connecting portion 60 moves along the second slit 614 in a direction approaching the first axis L1. Therefore, the first member 41 moves in a direction approaching the first axis L1 as shown by the arrow A1, while being supported by the holder 61. As a result, the holder 61 rotates around the first axis L1 in the direction indicated by the arrow B. At this time, the pinion 62 rides on the first rack 410 while rotating about the second axis L2, and the engagement position between the pinion 62 and the first rack 410 moves to the other side Z2 of the first rack 410 in the second direction Z. I do. In addition, the rotation of the pinion 62 causes the second rack 420 to ride on the pinion 62 on the side opposite to the first rack 410, and the meshing position between the pinion 62 and the second rack 420 in the second direction Z of the second rack 420. Move to one side Z1.

In the present embodiment, the opening of the frame 2 is also opened on the other side Z1 in the second direction Z of the opening / closing member 4, but such an opening is not used for taking the driven member 3 in and out.

  When the motor 50 rotates in the other direction from this open state, the rotational driving force of the motor 50 is transmitted to the rotating member 66 via the transmission mechanism 67 (the gear transmission mechanism 68 and the belt transmission mechanism 69) of the opening / closing mechanism 6. The rotating member 66 rotates around the third axis L3 in the other direction opposite to the one direction indicated by the arrow C, and the connecting portion 60 between the rotating member 66 and the first member 41 rotates around the third axis L3 with an arrow. It rotates in the other direction opposite to the one direction shown by C. For this reason, the connecting portion 60 moves along the second slit 614 in a direction away from the first axis L1. Therefore, as a result of the operation on the opposite side to the above-described operation being performed, the second member 42 moves to one side Z1 in the second direction Z, so that one side Z1 of the second member 42 in the second direction Z (opening / closing member) 4, the opening 20 is closed by the opening / closing member 4 on one side Z1) in the second direction Z.

(Switching mechanism 8)
FIG. 10 is an explanatory diagram of the switching mechanism 8 and the tilt drive mechanism 9 of the composite drive device 1 to which the present invention is applied. In this embodiment, the linear drive mechanism 7 has a switching mechanism 8. When the first carriage 71 starts moving to one side Y1 in the first direction Y, the switching mechanism 8 leaves the driven member 3 and the first carriage 71 in a released state in which the mechanical connection is released, After the first carriage 71 has moved a certain distance to one side Y1 in the first direction Y, the driven member 3 and the first carriage 71 are mechanically connected.

In the present embodiment, the switching mechanism 8 includes a lever 81 rotatably supported around an axis L6 extending in the third direction X with respect to the first carriage 71, and a first direction Y of the first carriage 71.
And a cam mechanism 85 that switches the posture of the lever 81 in accordance with the movement of the lever 81 to realize the released state and the connected state.

  In the present embodiment, the first carriage 72 has an L-shaped engagement portion 711 that engages with the feed screw 70 and an L-shape that overlaps from the engagement portion 711 to the base 32 of the driven member 3 from one side X1 in the third direction X. It has a connecting plate portion 712 and a convex portion 713 projecting from one end Z1 in the second direction Z of the connecting plate portion 712 to one side Y1 in the first direction Y. A circular hole (not shown) is formed in the connecting plate portion 712 at a position where the axis L6 passes, and a circular hole 816 is also formed in the lever 81 at a position where the axis L6 passes. A round bar-shaped shaft portion 86 is fitted in the hole of the connecting plate portion 712 and the hole 816 of the lever 81. Therefore, the first carriage 71 and the lever 81 can move integrally in the first direction Y, and the lever 81 can rotate around the axis L6 passing through the center of the shaft 86 with respect to the first carriage 71. It is. In addition, between the lever 81 and the first carriage 71, an urging member for urging the lever 81 about the axis L6 with respect to the first carriage 71 as shown by an arrow F2 as shown by an arrow F2. 88 (second biasing member) is provided. In this embodiment, the biasing member 88 is a torsion coil spring 880.

  The lever 81 has a first plate portion 811 extending from the position where the hole 816 is formed to the other side Y2 in the first direction Y, and a lever 81 from the position where the hole 816 is formed to one side Y1 in the first direction Y. And a second plate portion 812 that extends. While the edge of the first plate portion 811 is a cam surface 84, a round bar-shaped cam pin 82 is fixed to the frame 2 near the cam surface 84. In the present embodiment, the cam surface 84 and the cam pin 82 constitute a cam mechanism 85 that regulates the posture of the lever 81 around the axis L6.

  In the second plate portion 812 of the lever 81, a notch-shaped concave portion 813 recessed from the edge of one side Z1 in the second direction Z to the other side Z2 is formed at a position facing the convex portion 713 of the first carriage 72. Have been. Accordingly, the second plate portion 812 of the lever 81 has a first contact portion 814 formed of an edge of the other side Y2 in the first direction Y of the concave portion 813 and an edge of one side Y1 of the concave portion 813 in the first direction Y. A second contact portion 815 is formed. A round rod-shaped engaging shaft 34 protrudes from the base 32 of the driven member 3 on one side X1 in the third direction X.

(Operation of the switching mechanism 8)
FIG. 11 is an explanatory diagram illustrating the operation of the switching mechanism 8 of the combined drive device 1 to which the present invention has been applied. Note that FIG. 11 illustrates a state in which the posture of the lever 81 switches as the first carriage 71 moves to one side Y1 in the first direction Y, as indicated by arrows E1 and E2.

  First, at time t1 shown in FIG. 11, when the driven member 3 is at the standby position, the first carriage 71 and the lever 81 move with respect to the engagement shaft 34 of the driven member 3 on the other side Y2 in the first direction Y. And the lever 81 and the engagement shaft 34 are not engaged. Therefore, the mechanical connection between the driven member 3 and the first carriage 71 is released.

  Next, at time t11 shown in FIG. 11, when the motor 50 rotates in one direction and the feed screw 70 rotates in one direction, the first carriage 71 moves to one side in the first direction Y as indicated by an arrow E1. Move to Y1. As a result, the cam surface 84 of the lever 81 is pressed by the cam pin 82, and the lever 81 rotates in one direction around the axis L6 as shown by the arrow F1, and assumes an oblique posture.

Further, at time t12 shown in FIG. 11, when the first carriage 71 moves to one side Y1 in the first direction Y, the restriction of the posture of the lever 81 by the cam pin 82 is gradually released, and the urging force of the urging member 88 is released. As a result, as shown by arrow F2, it starts rotating in the other direction about axis L6. Then, at time t2 shown in FIG. 11, the lever 81 further rotates around the axis L6 in the other direction as shown by the arrow F2, and the engagement shaft 34 enters the inside of the concave portion 813 from the open end side of the concave portion 813. . As a result, the first contact portion 814 is located on the other side Y2 in the first direction Y with respect to the engagement shaft 34, and the second contact portion is located on one side Y1 in the first direction Y with respect to the engagement shaft 34. 815 is located, and the lever 81 and the driven member 3 are engaged with each other on both the first side Y1 and the second side Y2 in the first direction Y. This state is a connection state in which the driven member 3 and the first carriage 71 are mechanically connected and can move integrally. In this connection state, when the first carriage 71 further moves to one side Y1 in the first direction Y, the engagement shaft 34 is pressed by the first contact portion 814 of the lever 81 to one side Y1 in the first direction Y. Therefore, the driven member 3 moves to one side Y1 in the first direction Y together with the first carriage 71, and emerges from the opening 20 of the frame 2. In this state, the open end side of the concave portion 813 of the lever 81 is closed by the convex portion 713 of the first carriage 71. Therefore, the protrusion 713 functions as a protrusion for preventing the engagement shaft 34 from coming off from the recess 813 of the lever 81.

  Contrary to the above operation, when the motor 50 rotates in the other direction, the first carriage 71 moves to the other side Y2 in the first direction Y as shown by an arrow E2. As a result, the engagement shaft 34 of the driven member 3 is pressed by the second contact portion 815 of the lever 81 to the other side Y2 in the first direction Y. It moves to the other side Y2 in the first direction Y and returns from the opening 20 of the frame 2 to the inside of the frame 2. On the way, the posture of the lever 81 is switched by the cam mechanism 85, and the connection between the driven member 3 and the first carriage 71 is released.

(Configuration of tilt drive mechanism 9)
FIG. 12 is an explanatory diagram showing the operation of the tilt drive mechanism 9 of the combined drive device 1 to which the present invention has been applied. As shown in FIG. 8 and the like, a shaft 91 is disposed near an end of the guide member 74 on one side Z1 in the first direction Y, and the shaft 91 is fixed to the frame 2. In the present embodiment, the shaft 91 is caused by the driving force of the driving source 5 to tilt the tip end side of the driven member 3 that has reached the appearance position to one side Z1 or the other side Z2 in the second direction Z. It functions as the contact part 90. In the present embodiment, since the attitude of the driven member 3 is regulated by the guide member 74, the tilt drive mechanism 9 is moved after the restriction of the attitude of the driven member 3 by the guide member 74 is released at the appearance position. The tip side of the driving member 3 is inclined in the second direction Z.

  In this embodiment, the shaft 91 is disposed on the other side Z2 of the guide member 74 in the second direction Z. The base 32 of the driven member 3 is provided with an interference portion 33 projecting from the main body 31 to the other side Z2 in the second direction Z. Therefore, as described below with reference to FIG. 12, when the interference portion 33 contacts the contact portion 90 from the other side Y2 in the first direction Y, the distal end side of the driven member 3 moves around the axis L5. To the other side Z2 in the second direction Z.

  As shown in FIG. 12, the driven member 3 has the base 32 supported so as to be swingable about the axis L5 with respect to the first carriage 71 and the second carriage 72. The urging member 76 described with reference to FIG. 10 urges the driven member 3 in the direction indicated by the arrow S around the axis L5. Therefore, as shown by a dashed line in FIG. 12, the distal end side of the driven member 3 tends to incline toward the one side Z1 in the second direction Z around the axis L5, but the posture of the driven member 3 is as shown in FIG. As shown by the solid line in FIG.

  Then, as shown by an arrow E1, when the driven member 3 moves to one side Y1 in the first direction Y and the restriction of the posture of the driven member 3 by the guide member 74 is released, a dashed line in FIG. As shown, the distal end side of the driven member 3 is first inclined to one side Z1 in the second direction Z around the axis L5.

  Then, when the driven member 3 further moves to one side Y1 in the first direction Y, the interference portion 33 comes into contact with the contact portion 90 from the other side Y2 in the first direction Y, and the driven member 3 After the posture indicated by the solid line, as shown by the dotted line in FIG. 12, the distal end side of the driven member 3 is inclined around the axis L5 in the other side Z2 in the second direction Z. Here, since the urging member 76 urges the driven member 3 in the direction in which the interference portion 33 comes into contact with the contact portion 90, the distal end side of the driven member 3 exerts the urging force of the urging member 76. Against the other side Z2 in the second direction Z. Further, in the present embodiment, when the driven member 3 is tilted, the posture of the driven member 3 can be easily adjusted such that the driven member 3 can be largely tilted if the linear movement distance is long. Even in this case, since the position of the driven member 3 in the first direction Y does not change significantly, the change of the position of the driven member 3 in the first direction Y can be ignored. Instead of the urging member 76, an urging member is provided between the first carriage 71 and the driven member 3 so as to urge the interference portion 33 of the driven member 3 in a direction in which the interference portion 33 comes into contact with the contact portion 90. You may.

(Configuration of the feed screw 70)
FIG. 13 is an explanatory diagram of the feed screw 70 of the combined drive device 1 to which the present invention is applied. As shown in FIG. 13, the feed screw 70 used for the linear drive mechanism 7 has a spiral groove 706 formed on the outer peripheral surface of a round rod-shaped shaft body 705. Here, the feed screw 70 includes a first screw portion 701 provided with a spiral groove 706 at a first pitch P1, and a second screw portion 702 provided with a spiral groove 706 at a second pitch P2 shorter than the first pitch P1. And a boundary portion 703 between the first screw portion 701 and the second screw portion 702. In the boundary portion 703, the gap between the grooves continuously changes in the circumferential direction. Therefore, the engagement portion 711 of the first carriage 71 has an engagement portion (not shown) with the spiral groove 706 at one place.

  In the present embodiment, the feed screw 70 has second screw portions 702 on both sides of the first screw portion 701 in the first direction Y. The second screw portion 702 is a portion that drives the first carriage 71 in an initial period and a final period when the driven member 3 is moved from the standby position to the appearance position, and the first screw portion 701 is a member that drives the driven member 3. Is a portion for driving the first carriage 71 during an intermediate period when the is moved from the standby position to the appearance position.

(Another configuration example of the feed screw 70)
FIG. 14 is an explanatory diagram showing another configuration example of the feed screw 70 of the combined drive device 1 to which the present invention is applied. In the feed screw 70 shown in FIG. 14, similarly to the feed screw 70 described with reference to FIG. 13, the spiral groove 706 is provided on the outer peripheral side of the round rod-shaped shaft body 707. The feed screw 70 includes a first screw part 701 provided with a spiral groove 706 at a first pitch P1, a second screw part 702 provided with a spiral groove 706 at a second pitch P2 shorter than the first pitch P1, It has a boundary portion 703 between the first screw portion 701 and the second screw portion 702, and at the boundary portion 703, the interval between the grooves continuously changes in the circumferential direction. Therefore, the engagement portion 711 of the first carriage 71 has an engagement portion (not shown) with the spiral groove 706 at one place. The feed screw 70 has second screw portions 702 on both sides of the first screw portion 701 in the first direction Y.

  In the present embodiment, the spiral groove 706 is composed of a coil spring 708 arranged so as to spirally wind the outer peripheral surface of the shaft body 707. As the coil spring 708, a configuration in which a wire is spirally wound can be employed, and as shown in FIG. 14, a configuration in which a plate-like member whose axial direction is oriented in the thickness direction is spirally wound is employed. be able to.

  Here, the ends 708 a of the coil spring 708 on both sides in the axial direction are fixed to the shaft body 707. For this reason, the coil spring 708 can rotate around the axis integrally with the shaft body 707. Further, the coil spring 708 can be elastically deformed in a spirally wound portion in the axial direction.

  According to the feed screw 70 configured as described above, unlike the configuration described with reference to FIG. 13, there is no need to form a spiral groove 706 by performing machining on the outer peripheral surface of the round rod-shaped shaft body. The feed screw 70 can be manufactured efficiently. Further, even when an external force in the axial direction is applied to the first carriage 71, the force can be absorbed by the helically wound portion of the coil spring 708 being elastically deformed in the axial direction. Therefore, the first carriage 71 and the peripheral mechanism are hardly damaged.

(Operation of the entire composite driving device 1)
FIG. 15 is a timing chart showing the operation of the combined drive device to which the present invention is applied. In the combined drive device 1 of the present embodiment, the drive source 5 is common to the opening / closing mechanism 6, the linear drive mechanism 7, and the tilt drive mechanism 9. Therefore, when shifting from the state shown in FIGS. 1A and 2A to the state shown in FIGS. 1B and 2B, first, as shown in FIG. Is rotated in one direction, the opening / closing mechanism 6 slides the opening / closing member 4 until time t3, and opens the opening 20 on the one side Z1 in the second direction Z with respect to the opening / closing member 4.

  On the other hand, in the linear drive mechanism 7, since the mechanical connection between the first carriage 71 and the driven member 3 is delayed by the switching mechanism 8, the driven member 3 is moved from the time t2 to the first direction Y from the time t2. Is linearly moved toward one side Y1. Then, at time t3, after the driven member 3 reaches the appearance position, the linear drive mechanism 7 further moves the driven member 3 directly toward one side Y1 in the first direction Y until time t4, whereby tilt drive is performed. The mechanism 9 tilts the distal end side of the driven member 3 toward the other side Z2 in the second direction Z. Then, after the adjustment of the attitude of the driven member 3 is completed, the motor 50 is stopped at time t5.

  At this time, as described with reference to FIG. 13, in the feed screw 70, in the initial period and the final period when the driven member 3 is moved from the standby position to the appearance position, the first carriage 71 is moved to the second screw portion 702. , The first carriage 71 moves at a low speed. On the other hand, in an intermediate period when the driven member 3 is moved from the standby position to the appearance position, the first carriage 701 engages with the first screw portion 701, and thus the first carriage 71 moves at a high speed. I do. When the motor 50 is stopped, the first carriage 71 is in a self-locked state since the first carriage 71 is engaged with the second screw portion 702. Therefore, even if the mass of the driven member 3 acts on the first carriage 71 with the motor 50 stopped, the first carriage 71 does not move. Therefore, the state shown in FIG. 1B and FIG. 2B is maintained. During the period from time t3 to time t5, the opening / closing mechanism 6 is idled by the gear 683b, so that the position of the opening / closing member 4 does not change.

  When shifting from the state shown in FIG. 1B and FIG. 2B to the state shown in FIG. 1A and FIG. 2A, first, at time t6, the motor 50 starts rotating in the other direction. . As a result, the linear drive mechanism 7 linearly moves the driven member 3 toward the other side Y2 in the first direction Y. At this time, while the linear drive mechanism 7 linearly moves the driven member 3 toward one side Y1 in the first direction Y from time t6 to time t7, the tilt drive mechanism 9 tilts the tip side of the driven member 3. Return to the original posture. Then, when the linear driving mechanism 7 further moves the driven member 3 toward the other side Y2 in the first direction Y until time t8, the opening / closing mechanism 6 causes the opening / closing member 4 to move the opening / closing member 4 from time t8 to time t10. The opening 20 is closed by sliding. At that time, the linear drive mechanism 7 drives the first carriage 71 toward the other side Y2 in the first direction Y until time t9, and moves the driven member 3 directly toward the other side Y2 in the first direction Y. However, after time t9, the switching mechanism 8 stops driving the driven member 3. During the period from time t6 to time t8, the opening / closing mechanism 6 is idled by the gear 883b, so that the opening / closing member 4 is not driven.

(Main effects of this embodiment)
As described above, in the combined drive device 1 of the present embodiment, the opening and closing of the opening 20 by the opening and closing member 4 and the movement of the driven member 3 in the first direction Y between the standby position and the standby position are performed. Even when the operation is performed, the drive source 5 is common to the opening / closing mechanism 6 and the linear drive mechanism 7. Therefore, the configuration of the composite driving device 1 can be simplified. The drive source 5 is a motor 50 having a first output shaft 51 and a second output shaft 52 protruding toward opposite sides. Therefore, the opening / closing mechanism 6 can be operated by the driving force output from the first output shaft 51, and the linear driving mechanism 7 can be operated by the driving force output from the second output shaft 52. Therefore, a mechanism for branching and transmitting the output of the motor 50 to the linear drive mechanism 7 and the opening / closing mechanism 6 is unnecessary. Further, the composite drive device 1 of the present embodiment is provided with a tilt drive mechanism 9 that tilts the distal end side of the driven member 3 to one side Z1 or the other side Z2 in the second direction Z using the drive source 5 described above. Have been. Therefore, with a simple configuration using one drive source 5, opening / closing of the opening 20 by the opening / closing member 4, insertion / removal of the driven member 3 through the opening 20, and adjustment of the posture of the driven member 3 are performed. It can be carried out. Therefore, when the driven member 3 is the display member 30, the user can adjust the posture of the display member 30 to a posture in which an image can be easily viewed.

  In the present embodiment, the opening / closing mechanism 6 slides the opening / closing member 4 in the second direction Z to open the opening 20 on one side Z1 of the opening / closing member 4 in the second direction Z. For this reason, since the opening / closing member 4 does not protrude to the side where the driven member 3 appears, the presence of the opening / closing member 4 is unlikely to hinder. Further, in the open state, the first member 41 and the second member 42 are in an overlapping state, so that the dimension of the opening / closing member 4 in the second direction Z is reduced in the open state. Therefore, the presence of the opening / closing member 4 is unlikely to be an obstacle.

  Further, in the tilt drive mechanism 9, after the restriction of the attitude of the driven member 3 by the guide member 74 is released, when the linear drive mechanism 7 further drives the driven member 3 toward the appearance position, the driven member 3 And the contact portion 90 in the first direction Y to tilt the tip end of the driven member 3 in the second direction Z. Therefore, since the attitude of the driven member 3 is switched using the linear motion of the driven member 3, the configuration of the tilt drive mechanism 9 can be simplified. In addition, when the driven member 3 is tilted, if the linearly moving distance is long, the driven member 3 can be easily tilted, and the posture of the driven member 3 can be easily adjusted. Further, the driven member 3 includes a main body 31 protruding from the frame 2 when moved to the appearance position, and an interference part protruding from the main body 31 in the second direction Z and abutting on the abutting part 90 inside the frame 2. 33. For this reason, the attitude of the driven member 3 can be switched with a relatively simple configuration.

  The guide member 74 includes a first guide portion 741 that contacts the driven member 3 from the other side Z2 in the second direction Z, and a second guide portion 742 that contacts the driven member 3 from one side Z1 in the second direction Z. have. Therefore, the guide member 74 can linearly move the driven member 3 in an appropriate posture. The guide member 74 includes a first support portion 741 a having a tip end inclined to the other side Z2 in the second direction Z on one side Y1 in the first direction Y of the first guide portion 741, and a first guide portion 742 of the second guide portion 742. A second support portion 742a whose one end Y1 in the direction Y is inclined toward one side Z1 in the second direction Z is provided. For this reason, it is possible to suppress the driven member from excessively tilting in the second direction Z due to external vibration or the like.

  Further, the tilt drive mechanism 9 is configured to incline the distal end side of the driven member 3 to the other side Z2 in the second direction Z. For this reason, although the opening / closing member 4 is located on the side where the driven member 3 is inclined, even in such a case, in this embodiment, the opening / closing member 4 does not protrude to the side where the driven member 3 appears. The presence of 4 is unlikely to get in the way.

  In the linear drive mechanism 7, between the second carriage 72 and the driven member 3, there is provided an urging member 76 for urging the interference portion 33 of the driven member 3 in a direction in which the interference portion 33 comes into contact with the contact portion 90. Therefore, the tilt drive mechanism 9 can be reliably operated.

  Furthermore, since the switching mechanism 8 is provided in the linear drive mechanism 7, even when the first carriage 71 starts moving, the linear movement of the driven member 3 can be delayed. Therefore, when the driven member 3 is made to appear outside from the opening 20, interference between the driven member 3 and the opening / closing member 4 can be suppressed. Further, since the switching mechanism 8 includes the lever 81 and the cam mechanism 85, the connection between the driven member 3 and the first carriage 71 can be switched with a relatively simple configuration.

  The opening / closing mechanism 6 is configured such that the first member 41 is arranged in the second direction Z with respect to the second member 42 in the closed state, and the first member 41 and the second member 42 are moved in the first direction Y in the opened state. In the overlapping state, the end portions 41a and 42a on the other side Z2 in the second direction Z are in an oblique posture in which they are drawn into the frame 2. For this reason, the presence of the opening / closing member 4 is unlikely to hinder.

  The opening / closing mechanism 6 has a relatively simple configuration because the pinion 62, the first rack 410, and the second rack 420 slide the first member 41 and the second member 42 in the second direction Z. A closed state in which the member 41 and the second member 42 are arranged in the second direction Z and an open state in which the first member 41 and the second member 42 overlap in the first direction Y can be realized.

  In addition, since the opening / closing mechanism 6 includes the gear 683b in the gear transmission mechanism 68, after the opening / closing member 4 performs the opening / closing operation, the driving of the driven member 3 is continued. Can be stopped. Therefore, it is suitable for operating a plurality of mechanisms by a common drive source 5.

(Other embodiments)
In the above embodiment, in the opening / closing mechanism 6, in the open state, the end portions 41 a and 42 a of the opening / closing member 4 on the other side Z <b> 2 in the second direction Z are in an oblique posture in which they are drawn inside the frame 2. The end of the member 4 on one side Z1 in the second direction Z may be in an oblique posture in which the end is drawn inside the frame 2. Further, when the opening / closing member 4 is pulled into the frame 2 in the open state, the opening / closing member 4 is not limited to the slanted posture, and may be in a horizontal posture or a vertical posture and pulled into the frame 2. Good. Further, in the above-described embodiment, the transmission mechanism 67 is configured by the gear transmission mechanism 68 and the belt transmission mechanism 69 in the opening / closing mechanism 6, but the transmission mechanism 67 may be configured by only the gear transmission mechanism 68. In the above embodiment, in the switching mechanism 8, the engagement shaft 34 is formed on the driven member 3, and the first contact portion 814 and the second contact portion 815 are formed on the lever 81. 34 may be formed on the lever 81, and the first contact portion 814 and the second contact portion 815 may be formed on the driven member 3. In the above embodiment, the opening and closing mechanism 6 is operated by the driving force output from the first output shaft 51 of the motor 50, and the linear driving mechanism 7 is operated by the driving force output from the second output shaft 52. However, the present invention may be applied to a driving device having a configuration in which a driving force output from a common output shaft of the motor 50 is branched and transmitted to the opening / closing mechanism 6 and the linear driving mechanism 7. In the above embodiment, the feed screw 70 in which the pitch of the spiral groove 706 is switched in the axial direction is used. However, the present invention is applied to a driving device using the feed screw 70 in which the pitch of the spiral groove 706 is equal in the axial direction. May be. In the above embodiment, the opening / closing member 4 includes two members (the first member 41 and the second member 42). However, the present invention may be applied to a case where the opening / closing member 4 includes three or more members. In the above embodiment, when the switching mechanism 8 is configured, the engagement shaft 34 is provided on the driven member 3, and the lever 81 is provided with the concave portion 813 (the first contact portion 814 and the second contact portion 815). Alternatively, the engaging shaft 34 may be provided on the lever 81, and the driven member 3 may be provided with the concave portion 813 (the first contact portion 814 and the second contact portion 815).
