The first rack 410 and the second rack 420 are engaged with the pinion 62 from opposite sides.

(Open / close operation)
FIG. 7 is an explanatory diagram showing the operation of the opening / closing mechanism 6 of the composite drive device 1 to which the present invention is applied. In FIG. 7, the position of the opening / closing member 4 or the like in the closed state is indicated by a solid line, and the position of the opening / closing member 4 or the like in the opened state is indicated by a one-dot chain line.

As shown in FIG. 7, in the 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 standing up toward one side Y1 in the first direction Y. In the state, in the opening / closing member 4, the first member 41 is aligned with the second member 42 on the other side Z 2 in the second direction Z. In the closed state, the pinion 62 is positioned in the second portion 613b of the first slit 613. In addition, the pinion 62 is between the first member 41 and the second member 42 in the second direction Z. Therefore, a portion of the first rack 410 that is formed at an end portion of the step 412 that faces the one side Z1 in the second direction Z meshes with the pinion 62 from the other side Z2 in the second direction Z. Of the step portion 422, a portion formed at an end portion facing the other side Z 2 in the second direction Z is engaged with the pinion 62 from the one side Z 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 (gear transmission mechanism 68 and belt transmission mechanism 69) shown in FIG. Accordingly, the rotating member 66 rotates around the third axis L3 in one direction indicated by the arrow C, and the connecting portion 60 between the rotating member 66 and the first member 41 extends around the third axis L3 in one direction indicated by the arrow C. Rotate. For this reason, 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 the direction approaching the first axis L1 as indicated by the arrow A1 while being supported by the holder 61. As a result, the holder 61 rotates in the direction indicated by the arrow B around the first axis L1. At that time, the pinion 62 rides on the first rack 410 while rotating around the second axis L2, and the meshing position of the pinion 62 and the first rack 410 moves to the other side Z2 of the first rack 410 in the second direction Z. To do. Further, 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 of the pinion 62 and the second rack 420 is in the second direction Z of the second rack 420. Move to one side Z1. Therefore, the second member 42 moves to the other side Z2 in the second direction Z, as indicated by the arrow A2, and overlaps the one side Y1 in the first direction Y with respect to the first member 41 with the pinion 62 interposed therebetween. In such a state, the first member 41 and the second member 42 are in an oblique posture in which the

end portions

41 a and 42 a on the other side Z 2 in the second direction Z are drawn into the frame 2. Further, at least one side Z1 in the second direction Z of the second member 42 (one side Z1 in the second direction Z of the opening / closing member 4) is in an open state in which the opening 20 is opened. In this embodiment, the opening of the frame 2 is also open on the other side Z1 of the opening / closing member 4 in the second direction Z, but the opening is not used for taking in and out the driven member 3.

When the motor 50 rotates in the other direction from the 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 rotation 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 rotation member 66 and the first member 41 moves around the third axis L3. It rotates in the other direction opposite to the one direction indicated by C. For this reason, the connecting portion 60 moves along the second slit 614 in a direction away from the first axis line 1. Therefore, as a result of the operation on the opposite side to the above operation being performed, the second member 42 moves to the one side Z1 in the second direction Z. Therefore, the one side Z1 in the second direction Z of the second member 42 (opening / closing member) 4 in one side Z1) in the second direction Z, the opening 20 is closed by the opening / closing member 4.

(Switching mechanism 8)
FIG. 10 is an explanatory diagram of the switching mechanism 8 and the tilt drive mechanism 9 of the composite drive apparatus 1 to which the present invention is applied. In this embodiment, the linear drive mechanism 7 has a switching mechanism 8. The switching mechanism 8 is in a released state in which the mechanical connection between the driven member 3 and the first carriage 71 is released when the first carriage 71 starts moving to the one side Y1 in the first direction Y. After the first carriage 71 moves a certain distance 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 is configured to move the first carriage 71 in the first direction Y and the lever 81 supported so as to be rotatable around the axis L6 extending in the third direction X with respect to the first carriage 71. Along with this, there is provided a cam mechanism 85 that switches the posture of the lever 81 to realize the unlocked state and the connected state.

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

The lever 81 extends from the position where the hole 816 is formed to the other side Y2 in the first direction Y, and from the position where the hole 816 is formed to the one side Y1 in the first direction Y. The second plate portion 812 extends. While the edge of the first plate portion 811 is a cam surface 84, a round bar-like cam pin 82 is fixed to the frame 2 in the vicinity of the cam surface 84. In this 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.

The second plate portion 812 of the lever 81 is formed with a notch-shaped recess 813 that is recessed from the edge on the one side Z1 in the second direction Z to the other side Z2 at a position facing the projection 713 of the first carriage 72. Has been. Accordingly, the second plate portion 812 of the lever 81 has a first abutting portion 814 formed of an edge on the other side Y2 of the concave portion 813 in the first direction Y and an edge on the one side Y1 of the concave portion 813 in the first direction Y. The second contact portion 815 is formed. Further, a round bar-shaped engagement shaft 34 projects from the base 32 of the driven member 3 on one side X1 in the third direction X.

(Operation of switching mechanism 8)
FIG. 11 is an explanatory diagram showing the operation of the switching mechanism 8 of the composite drive device 1 to which the present invention is applied. FIG. 11 shows a state in which the posture of the lever 81 is switched as the first carriage 71 moves to one side Y1 in the first direction Y, as indicated by arrows E1 and E2.

First, at a time t1 shown in FIG. 11, when the driven member 3 is in the standby position, the first carriage 71 and the lever 81 are on the other side Y2 in the first direction Y with respect to the engagement shaft 34 of the driven member 3. 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, when the motor 50 rotates in one direction and the feed screw 70 rotates in one direction at time t11 shown in FIG. 11, the first carriage 71 moves in one direction 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 and assumes an oblique posture as indicated by an arrow F1.

Furthermore, when the first carriage 71 moves to one side Y1 in the first direction Y at time t12 shown in FIG. 11, the lever 81 is gradually released from the posture restriction by the cam pin 82, and the biasing force of the biasing member 88 is increased. Thus, as shown by the arrow F2, it starts to rotate around the axis L6 in the other direction. Then, at time t2 shown in FIG. 11, as indicated by an arrow F2, the lever 81 further rotates around the axis L6 in the other direction, and the engagement shaft 34 enters the inside of the recess 813 from the open end side of the recess 813. . As a result, the first contact portion 814 is positioned on the other side Y2 in the first direction Y with respect to the engagement shaft 34, and the second contact portion is on the one side Y1 in the first direction Y with respect to the engagement shaft 34. 815 is positioned, and the lever 81 and the driven member 3 are engaged on both the one side Y1 and the other side Y2 in the first direction Y. Such a 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 connected state, when the first carriage 71 further moves to the one side Y1 in the first direction Y, the engagement shaft 34 is pressed to the one side Y1 in the first direction Y by the first contact portion 814 of the lever 81. Therefore, the driven member 3 moves together with the first carriage 71 to one side Y1 in the first direction Y 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. Accordingly, the convex portion 713 functions as a convex portion for preventing the engagement shaft 34 from coming off from the concave portion 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 indicated by an arrow E2. As a result, the engagement shaft 34 of the driven member 3 is pressed against the other side Y2 in the first direction Y by the second abutting portion 815 of the lever 81, so that the driven member 3 together with the first carriage 71 is It moves to the other side Y2 of the first direction Y and returns to the inside of the frame 2 from the opening 20 of the frame 2. In the middle, 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 composite drive device 1 to which the present invention is applied. As shown in FIG. 8 and the like, a shaft 91 is disposed in the vicinity of the end portion on one side Z1 in the first direction Y of the guide member 74, and the shaft 91 is fixed to the frame 2. In this embodiment, the shaft 91 is driven by the tilt drive mechanism 9 that tilts the distal end side of the driven member 3 that has reached the appearance position toward the one side Z1 or the other side Z2 in the second direction Z by the driving force of the driving source 5. It functions as the contact portion 90. In this 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 regulation of the attitude of the driven member 3 by the guide member 74 is released at the appearance position. The front end side of the drive member 3 is tilted 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. Further, the base 32 of the driven member 3 is provided with an interference portion 33 that protrudes from the main body portion 31 to the other side Z2 in the second direction Z. Accordingly, as will be 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 is around the axis L5. To the other side Z2 in the second direction Z.

As shown in FIG. 12, the driven member 3 is supported so that the base 32 can swing around the axis L 5 with respect to the first carriage 71 and the second carriage 72. Further, 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. Accordingly, as shown by a one-dot chain line in FIG. 12, the tip side of the driven member 3 tends to tilt toward the one side Z1 in the second direction Z around the axis L5. As shown by a solid line in FIG.

Then, 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 as indicated by an arrow E1, a dashed line in FIG. As shown, the tip 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 part 33 comes into contact with the contact part 90 from the other side Y2 in the first direction Y, and the driven member 3 is shown in FIG. After passing through 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 to the other side Z2 in the second direction Z around the axis L5. Here, since the urging member 76 urges the driven member 3 in the direction in which the interference portion 33 abuts against the abutting portion 90, the distal end side of the driven member 3 is the urging force of the urging member 76. Against the other side Z2 in the second direction Z. In this embodiment, when the driven member 3 is tilted, the driven member 3 can be easily adjusted in posture, for example, if the linear movement distance is long, the driven member 3 can be largely tilted. Even in this case, since the position of the driven member 3 in the first direction Y does not change greatly, the change in the position of the driven member 3 in the first direction Y can be ignored. Instead of the urging member 76, an urging member that urges the interference portion 33 of the driven member 3 in the direction in which it abuts on the abutting portion 90 is provided between the first carriage 71 and the driven member 3. May be.

(Configuration of feed screw 70)
FIG. 13 is an explanatory diagram of the feed screw 70 of the composite drive device 1 to which the present invention is applied. As shown in FIG. 13, the feed screw 70 used in the linear drive mechanism 7 has a spiral groove 706 formed on the outer peripheral surface of a round bar-like 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. In addition, a boundary portion 703 between the first screw portion 701 and the second screw portion 702 is provided, and in the boundary portion 703, the groove interval continuously changes in the circumferential direction. For this reason, the engaging portion 711 of the first carriage 71 has an engaging portion (not shown) with the spiral groove 706 at one place.

In this embodiment, the feed screw 70 has second screw portions 702 on both sides in the first direction Y with respect to the first screw portion 701. The second screw portion 702 is a portion that drives the first carriage 71 in the initial period and the final period when the driven member 3 is moved from the standby position to the appearance position, and the first screw portion 701 is the driven member 3. This is a portion for driving the first carriage 71 in an intermediate period when moving the position 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 composite drive device 1 to which the present invention is applied. Also in the feed screw 70 shown in FIG. 14, the spiral groove 706 is provided on the outer peripheral side of the round bar-shaped shaft body 707, as in the feed screw 70 described with reference to FIG. 13. 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, and A boundary portion 703 between the first screw portion 701 and the second screw portion 702 is provided. In the boundary portion 703, the groove interval continuously changes in the circumferential direction. For this reason, the engaging portion 711 of the first carriage 71 has an engaging portion (not shown) with the spiral groove 706 at one place. The feed screw 70 has second screw portions 702 on both sides in the first direction Y with respect to the first screw portion 701.

In this embodiment, the spiral groove 706 includes a coil spring 708 disposed 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 wound spirally can be adopted, and as shown in FIG. 14, a configuration in which a plate-like member having a thickness direction in the axial direction is spirally wound is adopted. be able to.

Here, in the coil spring 708, both end portions 708a 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. In addition, the coil spring 708 can be deformed elastically in the axial direction at a portion wound spirally.

According to the feed screw 70 configured in this way, unlike the configuration described with reference to FIG. 13, there is no need to form the spiral groove 706 by machining the outer peripheral surface of the round bar-shaped shaft body. The feed screw 70 can be manufactured efficiently. Further, even if an external force in the axial direction is applied to the first carriage 71, the force can be absorbed by a portion of the coil spring 708 wound in a spiral manner being elastically deformed in the axial direction. Therefore, the first carriage 71 and the peripheral mechanism are not easily damaged.

(Operation of the composite drive device 1 as a whole)
FIG. 15 is a timing chart showing the operation of the composite drive device to which the present invention is applied. In the composite drive device 1 of this embodiment, the opening / closing mechanism 6, the linear drive mechanism 7, and the tilt drive mechanism 9 have the same drive source 5. Therefore, when the state shown in FIGS. 1 (a) and 2 (a) is shifted to the state shown in FIGS. 1 (b) and 2 (b), first, as shown in FIG. Is rotated in one direction, the opening and closing mechanism 6 slides the opening and closing member 4 until time t3, and opens the opening 20 on one side Z1 in the second direction Z with respect to the opening and 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 in the first direction Y from the time t 2 after the time t 1. Is moved straight toward one side Y1. Then, after the driven member 3 reaches the appearance position at time t3, when the linear drive mechanism 7 further moves the driven member 3 further toward the one side Y1 in the first direction Y until time t4, tilt driving 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 posture of the driven member 3 is completed, the motor 50 is stopped at time t5.

At that time, as described with reference to FIG. 13, in the feed screw 70, the first carriage 71 has the second screw portion 702 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 moves at a low speed. On the other hand, in the 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, so the first carriage 71 moves at a high speed. To do. When the motor 50 is stopped, the first carriage 71 is engaged with the second screw portion 702, so that the first carriage 701 is in a self-locked state. For this reason, 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 FIGS. 1B and 2B is maintained. In the period from time t3 to time t5, the opening / closing mechanism 6 is idled by the gear 683b, so the position of the opening / closing member 4 does not change.

When the state shown in FIGS. 1B and 2B is shifted to the state shown in FIGS. 1A and 2A, first, the motor 50 starts to rotate in the other direction at time t6. . As a result, the linear drive mechanism 7 moves the driven member 3 linearly toward the other side Y2 in the first direction Y. At that time, while the linear drive mechanism 7 linearly moves the driven member 3 from the time t6 to the time t7 toward the one side Y1 in the first direction Y, the tilt drive mechanism 9 tilts the tip side of the driven member 3. Return to the original posture. When the linear drive 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 moves the opening / closing member 4 between time t8 and 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 linearly moves the driven member 3 toward the other side Y2 in the first direction Y. However, after time t9, the switching mechanism 8 stops driving the driven member 3. In 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 form)
As described above, in the composite drive device 1 of this embodiment, the opening / closing member 4 is opened / closed by the opening / closing member 4 and the movement of the driven member 3 in the first direction Y between the standby position and the standby position. Even when performing, the opening / closing mechanism 6 and the linear drive mechanism 7 share the drive source 5. Therefore, the structure of the composite drive device 1 can be simplified. The drive source 5 is a motor 50 including a first output shaft 51 and a second output shaft 52 that protrude 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 leading 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. It has been. Therefore, the opening / closing member 4 is opened / closed by the opening / closing member 4, the driven member 3 is inserted / removed through the opening 20, and the attitude of the driven member 3 is adjusted with a simple configuration using one driving source 5. 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 this 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 on the side where the driven member 3 appears, the presence of the opening / closing member 4 is unlikely to become an obstacle. In the opened state, the first member 41 and the second member 42 are overlapped with each other, so that the dimension of the opening / closing member 4 in the second direction Z is reduced in the opened state. Therefore, the presence of the opening / closing member 4 is not easily disturbed.

In the tilt drive mechanism 9, after the restriction of the attitude of the driven member 3 by the guide member 74 is released, the driven member 3 is driven when the linear drive mechanism 7 further drives the driven member 3 toward the appearance position. And the abutting portion 90 are brought into contact with each other in the first direction Y, and the tip end side of the driven member 3 is inclined in the second direction Z. Accordingly, since the posture of the driven member 3 is switched using the direct movement of the driven member 3, the configuration of the tilt drive mechanism 9 can be simplified. Further, when the driven member 3 is tilted, if the distance of linear movement is long, the driven member 3 can be easily adjusted in posture, for example, the driven member 3 can be largely tilted. The driven member 3 includes a main body portion 31 that protrudes from the frame 2 when moved to the appearance position, and an interference portion that protrudes in the second direction Z from the main body portion 31 and contacts the contact portion 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 the 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 whose one end Y1 in the first direction Y of the first guide portion 741 is inclined to the other side Z2 in the second direction Z, and the first support portion 741 a of the second guide portion 742. And a second support portion 742a whose front end is inclined to one side Z1 in the second direction Z on one side Y1 in the direction Y. For this reason, it is possible to suppress the driven member from being excessively inclined in the second direction Z due to external vibration or the like.

Further, the tilt drive mechanism 9 is configured to tilt the leading end side of the driven member 3 toward 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, the opening / closing member 4 does not protrude on the side where the driven member 3 appears in this embodiment. The presence of 4 is difficult to get in the way.

Further, in the linear drive mechanism 7, a biasing member 76 that biases the interference portion 33 of the driven member 3 in a direction in which the interference portion 33 contacts the contact portion 90 is provided between the second carriage 72 and the driven member 3. Therefore, the tilt drive mechanism 9 can be reliably operated.

Furthermore, since the linear drive mechanism 7 is provided with the switching mechanism 8, the linear movement of the driven member 3 can be delayed even when the first carriage 71 starts to move. Therefore, when the driven member 3 appears outside 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.

Further, the opening / closing mechanism 6 has the first member 41 aligned 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 in the first direction Y in the opened state. The

end portions

41 a and 42 a on the other side Z 2 in the second direction Z are set 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 not easily disturbed.

In addition, the opening / closing mechanism 6 slides the first member 41 and the second member 42 along the second direction Z by the pinion 62, the first rack 410, and the second rack 420, and therefore has a relatively simple configuration and the first A closed state in which the member 41 and the second member 42 are aligned 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, the opening / closing member 4 continues to drive the driven member 3 after the opening / closing member 4 performs the opening / closing operation. Can be stopped. Therefore, it is suitable for operating a plurality of mechanisms by the common drive source 5.

(Other embodiments)
In the above embodiment, in the open / close mechanism 6, in the open state, the

end portions

41 a and 42 a on the other side Z 2 of the open / close member 4 in the second direction Z are in an oblique posture drawn into the inside of the frame 2. The end of one side Z 1 in the second direction Z of the member 4 may be in an oblique posture in which it is drawn into the inside of the frame 2. Further, when the opening / closing member 4 is drawn into the frame 2 in the open state, the state in which the opening / closing member 4 is drawn into the frame 2 in a horizontal posture or a vertical posture is not limited to an oblique posture.
