As a result, when a thick original is placed on the platen glass 23, the storage member 28 is placed on the platen glass 23 while maintaining the state in which the casing 27 is in contact with the upper surface of the original table 22. It can be rotated upward by the thickness of the document.

[Effect of the embodiment]
When the document cover 24 is changed from the closed position to the open position, the storage member 28 is changed from the immersive position to the exposed position by its own weight. Thereby, the opening 48 of the storage member 28 is exposed below the casing 27. The user of the multifunction machine 10 can insert the media tray 71 into the exposed opening 48. In other words, according to the present embodiment, the user of the multifunction device 10 can change the state of the multifunction device 10 from the media tray 71 to the storage member 28 only by a simple operation of changing the posture of the document cover 24 from the closed posture to the open posture. It can be in a state where it can be stored. That is, according to this embodiment, the operability for storing the media tray 71 in the multifunction machine 10 can be improved.

  Further, according to the present embodiment, the first engagement portion 40 slides in the up-down direction 7. Accordingly, when the document cover 24 is changed from the closed position to the open position, the storage member 28 can change its position from the immersive position to the exposed position by its own weight. When the document cover 24 is changed from the open position to the closed position, the storage member 28 can be changed from the exposed position to the immersive position by being pushed onto the upper surface of the document table 22.

  Further, according to the present embodiment, the sliding amount of the first engaging portion 40 is larger than the sliding amount of the second engaging portion 41. As a result, the storage member 28 rotates about the side away from the opening 48 as an axis. Accordingly, when the document cover 24 is changed from the closed position to the open position, the storage member 28 can change its position from the immersive position to the exposed position by its own weight.

  In addition, according to the present embodiment, the media tray 71 can be partially protruded from the opening 48 in a state of being stored in the storage member 28. Accordingly, the user of the multifunction machine 10 can easily take out the media tray 71 from the storage member 28 by picking the protruding portion of the media tray 71.

  Further, according to the present embodiment, when the document cover 24 is in the open posture, the media tray 71 is supported by the storage member 28 and also by the casing 27. As a result, the media tray 71 is stably held inside the storage member 28. Therefore, the possibility that the media tray 71 is deformed can be reduced.

  When the grip portion 34 and the opening 48 are formed on different sides, the user of the multifunction machine 10 inserts the media tray 71 from the opening 48 after gripping the grip portion 34 and changing the posture of the document cover 24. In addition, it is necessary to change the standing position or move the hand holding the media tray 71.

Therefore, the user of the multifunction machine 10 holds the media tray 71 in the storage member 28 or moves the media tray 71 to the storage member with less operation than the above after holding the grip 34 and changing the posture of the document cover 24. 28.

  Many of recent multifunction peripherals 10 can record images on a recording medium having high rigidity such as a CD or a DVD. In general, when image recording is performed on a recording medium having high rigidity, the recording medium is set on the media tray 71. The media tray 71 is a separate object from the multifunction machine 10 and is easily lost. However, according to this embodiment, the possibility of the loss can be reduced by storing the media tray 71 in the storage member 28.

  Further, according to the present embodiment, the concave portions 74 are provided on the top surfaces of the front end portion and the rear end portion in the insertion direction of the media tray 71. Therefore, the user of the multifunction machine 10 can store the media tray 71 even when the media tray 71 is inserted into the storage member 28 with the front end as the head, or when the media tray 71 is inserted into the storage member 28 with the rear end as the head. The media tray 71 accommodated in the member 28 can be easily taken out by grasping the recess 74.

As a result, the storage member 28 can rotate about the circular protrusion as a central axis.

[Modification 2 of the embodiment]
In the above-described embodiment, the housing member 28 changes its posture by rotating. However, the posture of the storage member 28 may be changed by other than rotation. For example, the housing member 28 may change its posture by moving in a direction orthogonal to the lower surface of the upper plate 29 of the casing 27. Such a posture change is caused by, for example, making the sliding amount of the first engaging portion 40 and the third engaging portion 42 the same as the sliding amount of the second engaging portion 41 and the fourth engaging portion 43. It is feasible.

[Modification 3 of the embodiment]
In the above-described embodiment, the configuration in which the media tray 71 is stored in the storage member 28 has been described.
