A medium ejection apparatus includes a placement mount on which media are placed, a restriction part that moves between a restriction position at which the restriction part restricts media ejected toward the placement mount and a retracted position retracted from the restriction position, and a processor that controls the restriction part by adjusting a restriction frequency on the basis of at least either an amount of movement of the restriction part from the retracted position to the restriction position or ejection intervals at which the media are ejected toward the placement mount, the restriction frequency being a frequency with which the restriction part performs a restriction operation for the media.

An electronic device includes a control unit that allows at least a first external power source to be connected thereto and is activated upon receipt of a predetermined power, and a power source connected to the control unit. In an activated state, the control unit performs enumeration processing between the control unit and the first external power source. The power source has charging unit capable of being charged by a charge current supplied from the first external power source, and output unit that outputs the predetermined power from the charging unit to the control unit in response to a connection between the control unit and the first external power source. The charging unit sets the charge current to a current value according to whether the enumeration processing is completed.

A recording apparatus including: an apparatus main body; a conveyance mechanism; a recorder; two first contact portions disposed in different positions in a conveyance direction of the recording medium and contactable with one surface of the recording medium; a cut mechanism configured to cut the recording medium, the cut mechanism being disposed between the two first contact portions and including a first blade, a second blade, and a second contact portion contactable with the other surface of the recording medium; and a cover configured to take an open position and a closed position in which a conveyance path of the recording medium is formed between the cover and the apparatus main body, the cover being formed with a groove, and the first blade being located in the groove when the cover is located in the closed position.

A serviceable machine includes a door assembly having a door, and a jointed assembly that extends between an external surface of the serviceable machine and the door. The jointed assembly is operable to move the door between a closed position in which an interior region of the serviceable machine is covered, and an open position in which the interior portion of the interior region is unobstructed. The jointed assembly may extend connectivity to the door when the door is in either the open or closed positions. Additionally, the door can mechanically and electrically decouple from the jointed assembly.

A recording apparatus includes an apparatus main body including: a transport unit that transports a medium; a liquid ejecting head that is provided above a transport path for the medium and performs recording by ejecting liquid onto the medium; and an accommodating unit that accommodates a waste liquid container configured to store waste liquid discharged from the liquid ejecting head, wherein a front surface of the apparatus main body is provided with a front wall and an operable operation unit, which are adjacent to each other in a width direction, and the accommodating unit is located between the front wall and the liquid ejecting head in a depth direction at a position that does not overlap the operation unit in the width direction.

A mount apparatus to be mounted on a top surface, in a vertical direction, of a main body of an image forming apparatus configured to form an image on a sheet, includes a latch member extending toward the main body from a surface facing the top surface of the main body and being rotatable around a rotational axis extending in a direction along a direction orthogonal to the vertical direction, and a biasing member configured to bias the latch member in a predetermined rotation direction. The latch member is inserted into the main body through an opening that is provided on the top surface of the main body and is engaged with the main body by a biasing force of the biasing member in a state where the mount apparatus is mounted on the main body.
