The drive mechanism main bodies 160 and 170 include first members 162 and 172 and second members 161 and 171. In addition, since the structure of the drive mechanism main bodies 160 and 170 is a symmetrical structure, only the structure of the drive mechanism main body 160 disposed at the right end portion of the main body 120 will be described here. For the drive mechanism main body 170 disposed in each part, the reference numerals of the 170th series are attached instead of the reference numerals of the 160th series indicating the respective parts of the drive mechanism main body 160, and description of each part is omitted.
The first member 162 has an arm 166 and a roller 167. In the present embodiment, the first member 162 is integrally configured by combining a plurality of parts such as the arm 166 and the roller 167. However, the present invention is not limited to this, and the first member is configured by one part. May be.

The arm 166 is a plate-like member having a substantially triangular shape, and is connected to the inner surface of the movable panel 130. Specifically, the vicinity of the end point 166 c positioned at the upper portion of the arm 166 and the first connection portion 133 of the movable panel 130 are connected, and the vicinity of the end point 166 d positioned at the lower front side of the arm 166 and the second end of the movable panel 130 are connected. The connection part 134 is connected.
Further, a side 166f connecting the end point 166e and the end point 166c located at the lower rear side of the arm 166 is gently curved in a convex shape. Further, a rack 166g that meshes with the first gear 155 is provided in the vicinity of the side 166f of the arm 166 along the side 166f. The arm 166 has a first part 166a and a second part 166b. The first part 166a and the second part 166b are arranged so as to be aligned in the vertical direction.
A first guide path 168 is formed in the first portion 166a. The first guide path 168 is a slit-like opening that penetrates both surfaces of the arm 166. The first guide path 168 is formed in the vicinity of the side 166 f of the arm 166. The first guide path 168 is formed in the arm 166 so as to have an arc shape that is gently curved in a convex shape along the side 166 f of the arm 166. For this reason, the first low-curved portion 168a, which is the space of the first guide path 168, has an arc shape that is gently curved in a convex shape along the side 166f of the arm 166.

Also, a second guide path 169 is formed in the second portion 166b. The second guide path 169 is a slit-like opening that penetrates both surfaces of the arm 166. The second guide path 169 is disposed at a position farther from the side 166 f of the arm 166 than the first guide path 168. Further, the second guide path 169 has an arm 166 so as to have a portion having an arc shape that is gently curved in a convex shape like the first guide path 168 and a portion bent forward from the end of the portion. Is formed. For this reason, the second low-curved portion 169a, which is a space of the second guide path 169 and is an upper region of the second guide path 169, has an arc shape that is gently curved in a convex shape. In addition, the 2nd low curved part 169a and the 1st low curved part 168a have the same circular arc center in the same virtual plane. For this reason, the second low-curved portion 169a is a region having the same arc center and a different curvature radius in the same virtual plane as the first low-curved portion 168a in the second guide path 169. . In addition, the bent portion 169b, which is the space of the second guide path 169 and is the lower region of the second guide path 169, has a larger curvature than the second low-curved portion 169a. Therefore, the bent portion 169b has an arc shape that is curved more convexly than the second low-curved portion 169a. In addition, the lower part of the 2nd low curved part 169a and the upper part of the bending part 169b are continuing. Further, when attention is paid only to the shapes of the first guide path 168 and the second guide path 169 formed in the arm 166, the first guide path 168 has a substantially I shape, and the second guide path 169 is substantially the same. It has a J-shape.

The roller 167 is disposed in the vicinity of the end point 166e of the arm 166. The roller 167 is rotatably supported by the arm 166. Furthermore, the roller 167 moves along a guide wall portion 165a of a guide portion 165 described later.
Moreover, the 1st member 162 takes a 1st state and a 2nd state. When the first member 162 is in the first state, the first member 162 is arranged so that the end point 166c and the end point 166d of the arm 166 are located on the same straight line. When the first member 162 is in the second state, the first member 162 is disposed so that the end point 166c of the arm 166 is positioned forward of the end point 166d. In the present embodiment, when the first member 162 is in the first state, the first member 162 is housed in the main body 120. Further, when the first member 162 is in the second state, the first member 162 is disposed so that the upper portion of the arm 166 protrudes from the main body 120.

The 2nd member 161 is being fixed to the outer side of the casing side 115, and is supporting the 1st member 162 so that a movement is possible. The second member 161 has a main body 163, a first sliding member 164a, and a second sliding member 164b. In the present embodiment, the second member 161 is integrally configured by combining a plurality of parts such as the main body 163, the first sliding member 164a, and the second sliding member 164b, but is not limited thereto. Instead, the second member may be composed of one component. The main body 163 includes a base body 163a and a guide 165.
The base portion 163a is a plate-like member having a substantially flat surface. The base portion 163a has substantially the same shape as the arm 166 of the first member 162 (see FIGS. 24 and 25). Further, a first gear 155 is disposed on the upper portion of the base portion 163a, and the base portion 163a supports the first gear 155 so as to be rotatable.

The guide portion 165 is erected from the rear end portion of the base portion 163a. Moreover, the guide part 165 has the guide wall part 165a and the curved part 165b. The guide wall portion 165a constitutes a portion other than the curved portion 165b of the guide portion 165, and extends downward from the lower end of the curved portion 165b. Further, the guide wall portion 165a has an arc shape that is gently curved in a convex shape. Note that the guide wall portion 165a, the first low-curved portion 168a, and the second low-curved portion 169a have the same arc center in the same virtual plane. Therefore, the guide wall portion 165a is a region of the guide portion 165 that has the same arc center and a different radius of curvature in the same virtual plane as the first low curved portion 168a and the second low curved portion 169a. That is.
The curved portion 165b constitutes the upper end portion of the guide portion 165. Further, the curved portion 165b has a larger curvature than the guide wall portion 165a. For this reason, the curved portion 165b has an arc shape that is curved more convexly than the guide wall portion 165a. Specifically, the curved portion 165b has a curved shape along the outer peripheral surface of the roller 167 of the first member 162, and the roller 167 is positioned at the curved portion 165b to restrict the sliding movement of the roller 167. be able to.

The first sliding member 164a has a substantially cylindrical shape, and is provided on the base portion 163a so as to protrude outward from the surface of the base portion 163a. The first sliding member 164a is disposed on the base portion 163a. Further, the first sliding member 164a is inserted through the first guide path 168 so as to slide with the first portion 166a. The first sliding member 164a locks the first portion 166a so that the movement of the first member 162 in the front-rear direction is allowed and the movement in the right direction is restricted. Thus, the 1st sliding member 164a is supporting the 1st member 162 by latching the 1st part 166a.
The second sliding member 164b has a substantially cylindrical shape, and is provided on the base portion 163a so as to protrude outward from the surface of the base portion 163a. Further, the second sliding member 164b is disposed below the first sliding member 164a in the base portion 163a. Further, the second sliding member 164b is inserted through the second guide path 169 so as to slide with the second portion 166b. The second sliding member 164b locks the second portion 166b so that the movement of the first member 162 in the front-rear direction is allowed and the movement in the right direction is restricted. Thus, the 2nd sliding member 164b is supporting the 1st member 162 by latching the 2nd part 166b.

With this configuration, in the drive mechanism 150, the first gear 155 and the second gear 156 rotate via the drive gear 154 when the motor 152 is driven. As the first gear 155 rotates, the rack 166g that meshes with the first gear 155 is driven, and the first member 162 moves relative to the second member 161. At this time, the positions of the end points 166c, 166d, and 166e of the arm 166 move along the first guide path 168, the second guide path 169, and the guide wall portion 165a, respectively. For this reason, the locus drawn by the end points 166c, 166d, and 166e of the arm 166 is gently curved in a convex shape. Further, the rotation of the second gear 156 drives the rack 176 g that meshes with the second gear 156, and the first member 172 moves relative to the second member 171. At this time, the positions of the end points 176c, 176d, and 176e of the arm 176 move along the first guide path 178, the second guide path 179, and the guide wall portion 175a, respectively. For this reason, the locus drawn by the end points 176c, 176d, and 176e of the arm 176 is gently curved in a convex shape.

In the present embodiment, as described above, the drive mechanism 150 other than the transmission shaft is stored in the storage spaces S, S formed between the casing side surfaces 115, 115 and the main body side surface portions 121, 121. . Specifically, the drive mechanism main body 160, the motor 152, the drive gear 154, and the first gear 155 are stored in the right storage space S. More specifically, the second member 161 is disposed in front (right side) of the casing side surface 115, the first member 162 is disposed in front (right side) of the second member 161, and the first member 162 A motor 152 is disposed in front (right side).

The moving member 164a is located, the second sliding member 164b is located at the upper end portion 169x of the second guide path 169, that is, the upper end portion 169ax of the second low curved portion 169a, and the roller 167 is located at the lower end portion 165aa of the guide wall portion 165a. It is arranged to be located. Thereby, the 1st connection parts 133 and 133 are arranged at position P1 shown in FIG.

When the posture of the movable panel 130 is switched from the driving stop posture to the driving posture, the first member 172 has a lower end portion 178y of the first guide path 178 close to the first sliding member 174a, as shown in FIG. The lower end portion 179ay of the second low curved portion 179a of the second guide path 179 is close to the second sliding member 174b, and the roller 177 is close to the upper end portion of the guide wall portion 175a with respect to the second member 171. Moving. Further, when the posture of the movable panel 130 is switched from the driving stop posture to the driving posture, the first member 162 has the lower end portion 168y of the first guide path 168 close to the first sliding member 164a, and the second guide path 169. The lower end portion 169ay of the second low curved portion 169a moves closer to the second sliding member 164b, and the roller 167 moves relative to the second member 161 in the direction closer to the upper end portion of the guide wall portion 165a. At this time, the portions defining the first low-bending portions 168a and 178a in the first portions 166a and 176a slide with respect to the first sliding members 164a and 174a, and the second low portions in the second portions 166b and 176b. The portions defining the curved portions 169a and 179a slide relative to the second sliding members 164b and 174b, and the rollers 167 and 177 slide relative to the guide wall portions 165a and 175a. For this reason, the arms 166 and 176 slide and move obliquely forward and upward along the first low curved portions 168a and 178a, the second low curved portions 169a and 179a, and the guide wall portions 165a and 175a. Since the first connecting portions 133 and 133 move integrally with the arms 166 and 176, they slide and move obliquely forward and upward from the position P1 shown in FIG. Therefore, as shown in FIG. 27, the movable panel 130 slides forward and obliquely upward with respect to the main body 120.

The first members 162 and 172 are moved to the positions where the second sliding members 164b and 174b and the boundary portions between the second low curved portions 169a and 179a of the second guide paths 169 and 179 and the bent portions 169b and 179b are close to each other. When moving with respect to the two members 161, 171, the first members 162, 172 slide while moving with respect to the second members 161, 171. Specifically, the positions of the second sliding members 164b and 174b move from the upper end portions 169bx and 179bx of the bent portions 169b and 179b to the lower end portions 169by and 179by, and the rollers 167 and 177 are bent from the guide wall portions 165a and 175a. When moving to the parts 165b and 175b, the first members 162 and 172 rotate by a predetermined angle with respect to the second members 161 and 171 using the first sliding members 164a and 174a as rotation fulcrums. At this time, the first sliding member 164a is positioned in the vicinity of the lower end portions 168y and 178y of the first guide paths 168 and 178. Thereafter, the first sliding members 164a and 174a are positioned at the lower ends 168y and 178y of the first guide paths 168 and 178, and the lower ends 169y and 179y of the second guide paths 169 and 179, that is, The second sliding members 164b and 174b are positioned at the lower end portions 169by and 179by of the bent portions 169b and 179b, and the rollers 167 and 177 are moved relative to the second members 161 and 171 so that they are positioned at the curved portions 165b and 175b.

In the present embodiment, the first members 162 and 172 move relative to the second members 161 and 172. The movable panel 130 is connected to the first members 162 and 172, and the second members 161 and 172 are fixed to the main body 120. Further, when the movable panel 130 takes the driving posture, the movement of the arms 166 and 176 is regulated by the second sliding members 164b and 174b being positioned at the lower end portions 169by and 179by of the bent portions 169b and 179b. The first members 162 and 172 are supported. That is, when the movable panel 130 takes the driving posture, the movable panel 130 and the first members 162 and 172 can be shared and supported by the second sliding members 164b and 174b and the first gear 155. For this reason, for example, the lower end portion of the second guide path is not bent, the lower end portion of the first guide path is bent forward, and the first sliding member defines the lower end portion of the first guide path. Compared to the arm to be locked, the first gear 155 and the second gear 156 are the sliding members that support the arm from the part that contacts the arm 166 and 176 and supports the arm 166 and 176. Since the distance to the second sliding members 164b and 174b is long, the load applied to the motor 152 in order to maintain the posture of the movable panel 130 can be reduced. Further, compared to the case where the arms 166 and 176 are supported only by the first gear 155 and the second gear 156, the load applied to the motor 152 can be reduced. Further, when the second sliding members 164b and 174b are positioned at the lower end portions 169by and 179by of the bent portions 169b and 179b, the second sliding members 164b and 174b are lower end portions 169by and 169by of the bent portions 169b and 179b, respectively. For example, the load applied to the motor 152 is reduced compared to the case where the second sliding members 164b and 174b are positioned at the lower end portion 179y of the second low curved portion 179a of the second guide path 179 before being positioned at 179by. be able to. Note that the center of gravity of the movable panel 130 is located in front of the main body 120 with respect to the positions of the second sliding members 164b and 174b.

Further, in the present embodiment, the first members 162 and 172 become the second members 161 and 171 with the first sliding members 164a and 174a located in the vicinity of the motor 152 and the first gear 155 or the second gear 156 as rotation fulcrums. For example, compared with the case where the first member rotates with respect to the second member using the second sliding member as a rotation fulcrum, the motor 152 is applied when the first members 162 and 172 rotate. The load can be reduced.

(B)
In the above embodiment, the first gear 155 and the second gear 156 are driven by one motor 152. Alternatively, the first gear and the second gear may be driven by individual motors. This eliminates the need for a transmission shaft.

(C)
In the above embodiment, the first guide path 168 and the second guide path 169 are slit-like openings that penetrate both surfaces of the arm 166.
Alternatively, as long as the first sliding member or the second sliding member is slidable, the first guide path and the second guide path may not be openings. For example, the first guide path and the second guide path may be groove-shaped depressions provided in the arm.
(D)
In the above embodiment, the first member 162, 172 is moved relative to the second member 161, 171 by the drive unit 151. The first members 162 and 172 are connected to the movable panel 130, and the second members 161 and 171 are fixed to the casing side surface 115 of the main body 120 (see FIG. 31A).
