Therefore, when the container 13 moves along the mounting direction after the locking portion 39 engages with the start end of the first inclined groove 78a, the locking portion 39 moves along the inclination of the first inclined groove 78a and the locking groove 78b. , The second inclined groove 78c is engaged in this order so as not to return from the locking groove 78b to the first inclined groove 78a or from the second inclined groove 78c to the locking groove 78b.

The locking groove 78b has a shape in which the portion between the start end and the end is bent toward the tip end side, and the bent portion is located at the back in the mounting direction of the locking portion 39 and engages with the locking portion 39. It has a mating engaging wall portion 78d. Then, when the locking portion 39 engages with the engaging wall portion 78d, the container 13 is restricted from moving in the taking-out direction while receiving the urging force of the urging portion 47c, and the container 13 is maintained in a state of being mounted on the mounting portion 14. Will be done.

When the container 13 is locked to the locking portion 39, the mounting of the container 13 on the mounting portion 14 is completed. Further, the liquid container 20 engaged with the container 13 is restricted from moving in the taking-out direction away from the mounting portion 14 by locking the container 13 to the locking portion 39.

In this way, since the object to be locked by the locking portion 39 is the container 13, not only the mounting body 50 accommodating the liquid container 20 but also the container 13 alone can be mounted on the mounting portion 14. On the other hand, when the liquid container 20 is inserted into the storage space in a single state in which it does not engage with the container 13, the liquid container 20 is not locked to the locking portion 39, so that the liquid container 20 is placed at the tip of the liquid supply unit 61. The pressing portion 47b comes into contact and is pushed back by the urging force of the urging portion 47c. Therefore, the liquid container 20 cannot be mounted on the mounting portion 14 by itself.

Further, when the container 13 is mounted alone on the mounting portion 14 without engaging with the liquid container 20, the connection terminal 53 is not connected to the terminal portion 40, so that the control device 42 has the liquid container 20 as the connecting portion 32. It can be determined that it is not connected to.

By the way, when the container 13 inserted into the accommodation space is pushed in the mounting direction by the user, and the locking portion 39 engages with the engaging groove 78 and moves relative to the first inclined groove 78a, the container 13 Is receiving the urging force of the urging unit 47c. Therefore, after the locking portion 39 shifts from the first inclined groove 78a to the locking groove 78b and before engaging with the engaging wall portion 78d, the container 13 is slightly taken out by the urging force of the urging portion 47c. Move in the direction.

At the end of the movement in the take-out direction, the locking portion 39 comes into contact with the engaging wall portion 78d to generate a clicking sound (clicking sound), so that the container 13 is installed. It is possible to give the user a feeling or a feeling (click feeling) of having done it. As a result, it is possible to suppress the occurrence of improper mounting due to insufficient insertion of the container 13.

When the container 13 is pushed in the mounting direction by the user while the locking portion 39 is engaged with the engaging wall portion 78d, the locking portion 39 has a second inclined groove 78c along the inclination of the locking groove 78b. Then, along the inclination of the second inclined groove 78c, the urging force of the urging portion 47c moves toward the end of the second inclined groove 78c, and the engagement with the engaging groove 78 is disengaged. Then, the container 13 moves in the take-out direction by the urging force of the urging portion 47c, and the base end portion of the container 13 comes out of the frame body 24 and the exterior body 12 from the insertion port 25.

At this time, if the liquid container 20 is engaged with the container 13, the supply port 52 separates from the connecting portion 32 and the liquid is separated from the connecting portion 32 as the container 13 moves in the take-out direction by the urging force of the urging portion 47c. At the same time that the connection of the container 20 is released, the connection terminal 53 is separated from the terminal portion 40 and the liquid container 20 is released from the mounting portion 14.

It is preferable that the bottom of the container 13 is provided with a rail engaging portion 13c along the unevenness of the guide rail 26. The guide rail 26 clarifies the movement path of the container 13 when it is mounted on the mounting portion 14, and even when a plurality of mounting bodies 50 or containers 13 are inserted into one accommodation space, the containers 13 arranged next to each other are placed next to each other. It can be moved without unnecessary contact.

The spacing or the number of configurations of the guide rails 26 in the width direction may be configured to be different for each width of the container 13 to be mounted. In this case, since the shape of the rail engaging portion 13c can be unified in the containers 13 having the same width, the members can be made common. Alternatively, if the plurality of sets of guide rails 26 are configured so that the intervals or the number of configurations in the width direction are different from each other, erroneous mounting of the container 13 can be suppressed.

Further, it is preferable that three or more (four in this embodiment) leg portions 13d for keeping the posture of the container 13 horizontal are projected from the bottom of the container 13. As a result, the container 13 can be positioned in the vertical direction, so that the liquid container 20 and the connecting portion 32 can be appropriately connected. Further, since the posture of the container 13 can be correctly maintained, the connection between the liquid container 20 and the connecting portion 32 can be appropriately maintained.
