a pair of the first attachment units are attached near the discharge port, and

in a state where the holding member is connected with each of the pair of first attachment units, in a case where force containing a component in a first direction which is, as viewed from one of the pair of first attachment units, directed to an opposite one of the pair of first attachment units is applied to the holding member, the holding member transitions from the first state to the second state.

6 . The printing medium accommodating apparatus according to claim 5 , wherein in a case where force containing a component in a second direction opposite to the first direction is applied to the holding member, the holding member does not transition from the first state to the second state.

7 . The printing medium accommodating apparatus according to claim 1 , wherein

the receiving member is capable of deforming with a weight thereof, and

in a state where the receiving member is attached to the first attachment unit and the second attachment unit, the receiving member takes on a substantially U shape.

8 . The printing medium accommodating apparatus according to claim 1 , wherein the first attachment unit further includes a spring member configured to bias the pressing member against the turning member.

9 . The printing medium accommodating apparatus according to claim 1 , wherein the pressing member includes a sliding member configured to press the side surface of the turning member, the sliding member including a restricting face configured to restrict the sliding member from turning together with the turning member.

10 . The printing medium accommodating apparatus according to claim 1 , wherein the first attachment unit includes an insertion member configured to be inserted into the printing apparatus, the insertion member including an abutting portion provided at a lower portion of the insertion member, and

wherein, in a state where the first attachment unit is attached to the printing apparatus, a portion of the abutting portion is positioned below the printing apparatus.

11 . The printing medium accommodating apparatus according to claim 10 , wherein the abutting portion is configured to abut a desk that supports the printing apparatus.

12 . A printing apparatus comprising:

a discharge port;

a printing medium accommodating apparatus for stacking printing media discharged from the discharge port, the printing medium accommodating apparatus including:

a receiving member configured to receive a printing medium discharged from a discharge port of the printing apparatus in a discharge direction;

a holding member having a holding portion configured to hold one end of the receiving member in the discharge direction; a first attachment unit configured to be attached to the printing apparatus and configured to enable connection with the holding member; and

a second attachment unit configured to be capable of attaching an opposite end of the receiving member on an opposite side to the one end in the discharge direction to the printing apparatus,

wherein the first attachment unit includes a turning member that is rotatable about a rotation axis, the turning member being configured to turn while holding an end portion of the holding member,

wherein the first attachment unit includes a pressing member configured to press a side surface of the turning member in a direction crossing the rotation axis,

wherein the turning member is held at a selected rotational position by friction between the pressing member and the turning member, and

wherein the holding member transitions from a first state where the holding member is connected with the first attachment unit to a second state where the holding member is separated from the first attachment unit; and

an insertion slot configured such that the first attachment unit is attached to the insertion slot.

13 . The printing apparatus according to claim 12 , wherein deformation of the holding member causes the holding member to transition from the first state to the second state.

14 . The printing apparatus according to claim 12 , wherein

the holding member has the holding portion and a connecting portion configured to be connected with the first attachment unit, and

deformation of a joint portion between an end portion of the holding portion and the connecting portion causes the holding member to transition from the first state to the second state.

15 . The printing apparatus according to claim 12 , wherein

the holding portion is configured to be expandable and contractable, and

expansion and contraction of the holding portion cause the holding member to transition from the first state to the second state.

16 . The printing apparatus according to claim 12 , wherein

a pair of the first attachment units are attached near the discharge port, and

in a state where the holding member is connected with each of the pair of first attachment units, in a case where force containing a component in a first direction which is, as viewed from one of the pair of first attachment units, directed to an opposite one of the pair of first attachment units is applied to the holding member, the holding member transitions from the first state to the second state.

17 . The printing apparatus according to claim 16 , wherein in a case where force containing a component in a second direction opposite to the first direction is applied to the holding member, the holding member does not transition from the first state to the second state.
