The protrusion 61 </ b> B of the right lock member 61 enters the recess 65 </ b> B of the receiving portion 65 by the biasing force of the third biasing member 64. That is, the protrusion 61B is engaged with the recess 65B. When the protrusion 61B is engaged with the recess 65B, the first flat surface 61C comes into contact with the third flat surface 65C, and the second flat surface 61D comes into contact with the fourth flat surface 65D. The same applies to the lock member 62 on the left side, and a detailed description thereof will be omitted.

  When opening the second housing 12, the gripping portion 61F of the right lock member 61 is pushed leftward. As the grip portion 61F moves leftward, the right lock member 61 and the left lock member 62 move leftward. When the lock member 61 moves in the left direction, the protruding portion 61B is detached from the recessed portion 65B. That is, the protrusion 61B can move upward. The same applies to the lock member 62 on the left side, and a detailed description thereof will be omitted.

  When the grip portion 61F is moved upward, the second housing 12 rotates in a direction away from the first housing 11. The right lock member 61 and the left lock member 62 are moved rightward by the urging force of the third urging member 64.

  When closing the second housing 12, the second housing 12 rotates in a direction approaching the first housing 11. As shown in FIG. 8A, when the second housing 12 rotates toward the first housing 11, the first inclined surface 61 </ b> E of the right lock member 61 contacts the second inclined surface 65 </ b> E of the receiving portion 65. . As shown in FIG. 8B, the lock member 61 is guided leftward by the first inclined surface 61E and the second inclined surface 65E as the second housing 12 rotates. The lock member 61 moves leftward and downward against the urging force of the third urging member 64. As shown in FIG. 8C, as the second housing 12 is rotated, the lock member 61 has the first flat surface 61C positioned below the third flat surface 65C and the protruding portion 61B is a recessed portion 65B. Move to the left side of. As shown in FIG. 8D, the protrusion 61 </ b> B enters the recess 65 </ b> B by the urging force of the third urging member 64. That is, the protrusion 61B is engaged with the recess 65B. When the protrusion 61B is engaged with the recess 65B, the first flat surface 61C comes into contact with the third flat surface 65C, and the second flat surface 61D comes into contact with the fourth flat surface 65D. The same applies to the lock member 62 on the left side, and a detailed description thereof will be omitted.

[3. Effects of the embodiment]
(1) As described above, according to the image reading apparatus 1 of the present embodiment, the following operational effects can be obtained. When the second housing 12 is in a closed state, as shown in FIGS. 5 to 7, the right lock member 61 and the left lock member 62 are engaged with the receiving portion 65 and the receiving portion 66, respectively. The protruding portion 61 </ b> B of the right lock member 61 enters the recess 65 </ b> B of the receiving portion 65 by the biasing force of the third biasing member 64. That is, the protrusion 61B is engaged with the recess 65B. Since the first flat surface 61C is in contact with the third flat surface 65C in a state where the protruding portion 61B is engaged with the recess 65B, the lock member 61 is restricted from moving upward. Since the second flat surface 61D contacts the fourth flat surface 65D in a state where the protruding portion 61B is engaged with the recess 65B, the lock member 61 is restricted from moving downward. The same applies to the lock member 62 on the left side. Such engagement between the locking members 61 and 62 on the first housing 11 side and the receiving portions 65 and 66 on the second housing 12 side causes a backlash between the first housing 11 and the second housing 12. Can be reduced.

  (2) Further, according to the image reading apparatus 1 of the present embodiment, the lock members 61 and 62 are respectively engaged with the receiving portions 65 and 66 by the operation of rotating the second housing 12 toward the first housing 11. Since it can be combined, it is convenient for the user.

  (3) According to the image reading apparatus 1 of the present embodiment, the second inclined surfaces 65E and 66E have an angle of 45 to 90 degrees with respect to the right direction. As a result, when the second housing 12 is rotated toward the first housing 11, the locking members 61 and 62 are guided by the second inclined surfaces 65E and 66E while the third urging member 64 is attached. The movement to the left against the force is smooth. Therefore, user convenience is further improved.

  (4) Further, according to the image reading apparatus 1 of the present embodiment, the third urging member 64 is provided as the urging member that urges the lock members 61 and 62 toward the right direction. Since the compression spring generally has better durability than the tension spring, the use of the third biasing member 64 as the biasing member makes the biasing member more durable than the case where the tension spring is used as the biasing member. Can be improved. In general, since the compression spring that exerts the urging force in the compressed state requires less space than the tension spring that exerts the urging force in the pulled state, the third urging member 64 is attached. By using it as a biasing member, the space occupied by the biasing member can be made smaller than when a tension spring is used as the biasing member, and the degree of design freedom of the image reading apparatus 1 can be increased.

  (5) Further, according to the image reading apparatus 1 of the present embodiment, the two locking members 61 and 62 and the two receiving portions 65 and 66 are provided, and one locking member 61 is the right end of the second housing 12. And the other locking member 62 is disposed at the left end of the second housing 12, and the one receiving portion 65 is disposed at the right end of the first housing 11, while the other The receiving portion 66 is disposed at the left end portion of the first housing 11, and the third urging member 64 is disposed between the lock member 61 and the lock member 62. As a result, when the second housing 12 rotates and approaches the first housing 11, the lock members 61, 62 on the first housing 11 side and the second at the left and right ends of the image reading apparatus 1. Since the receiving portions 65 and 66 on the housing 12 side are respectively engaged, backlash between the first housing 11 and the second housing 12 can be reduced at any of the left and right end portions of the image reading apparatus 1.

  (6) Also, according to the image reading apparatus 1 of the present embodiment, the right lock member 61 has the gripping portion 61F, and the second housing 12 is longer in the left-right direction than the gripping portion 61F, and the upper or lower side. When viewed from the side, the gripping portion 61F has a cutout portion 12F positioned inside thereof. As a result, the gripping portion 61F located inside the notch 12F as viewed from above or below can move in the left-right direction in the notch 12F, and the left-right direction of the lock member 61 provided with the gripping portion 61F. Smooth movement to Therefore, user convenience is further improved.

  (7) Further, according to the image reading apparatus 1 of the present embodiment, the third urging member 64 as the urging member includes the lock member 61 in which the grip portion 61F is formed among the two lock members 61 and 62. Energize to the right. As a result, the distance between the urging member and the gripping portion is closer than when the urging member such as a compression spring urges the lock member 62 in which the gripping portion is not formed in the right direction. The transmission efficiency in which the operating force for operating the grip portion is transmitted to the lock member that is biased by the biasing member is good. Therefore, the operability of the gripper 61F is good.
