An anti-slip device for preventing an installed image forming device from slipping on an installation surface. The anti-slip device includes an operation portion that can be moved by a user, a movable portion, and an anti-slip member. The movable portion has a bottom surface and moves in conjunction with movement of the operation portion to move from a first position to a second position above the first position. The anti-slip member is provided on the bottom surface of the movable portion and comes into contact with the installation surface when the movable portion is in the first position and separates from the installation surface when the movable portion is raised from the first position to the second position.

A liquid discharge apparatus includes: a cartridge including a first liquid chamber and a first flow path; a tank including a second liquid chamber and a third flow path, at least one of the first flow path and the third flow path communicating the first and second liquid chambers when the cartridge is installed in an installation case; and a controller configured to: when the cartridge is installed in the installation case, determine a liquid amount Vs based on an outflow amount Qc of liquid flowed out from the cartridge toward the tank and a discharge liquid amount; determine whether elapsed time reaches standby time after determining that the liquid amount Vs reaches a first threshold value; and when the elapsed time reaches the standby time, perform image recording of next unit recording area.

To provide a fastening member configured to fasten a hollow member including a first wall and a second wall, the first wall and the second wall each other, and another member having a screw hole. The fastening member includes a bolt having a screw portion to be inserted through a second hole provided on the second wall and to be screwed into the screw hole, and a case to be inserted into a first hole provided on the first wall, the case being configured to accommodate the bolt. While the case is inserted into the first hole, a tool used for a task of fastening the bolt is inserted into the case from a side of the first wall opposite to the other side of the first wall facing the second wall.

An inkjet printing device for printing to a recording medium includes a printing unit that has a plurality of print bars that respectively have one or more print heads. The printing device also includes a transfer printing sled to guide the recording medium, which can be moved into and out of a space below the printing unit. In a print operation state, the transfer printing sled is arranged in the space and guides the recording medium during printing. In a maintenance operation state, the transfer printing sled is moved out of the space. The printing device also includes at least one cleaning element for cleaning at least one print head of the printing module.

In the transport direction of the recording medium, the at least one cleaning element is arranged laterally next to the space in the print operation state and in this space in the maintenance operation state.

A liquid discharge apparatus includes: a cartridge including a first liquid chamber and a first flow path; a tank including a second liquid chamber and a third flow path, at least one of the first flow path and the third flow path communicating the first and second liquid chambers when the cartridge is installed in an installation case; and a controller configured to: when the cartridge is installed in the installation case, determine a liquid amount Vs based on an outflow amount Qc of liquid flowed out from the cartridge toward the tank and a discharge liquid amount; determine whether elapsed time reaches standby time after determining that the liquid amount Vs reaches a first threshold value; and when the elapsed time reaches the standby time, perform image recording of next unit recording area.

A storage case 30 for a portable printer according to an embodiment of the present invention includes: a case body 31 configured to store a portable printer 1; a lower cover 32 configured to open and close so as to cover the lower part of the front surface in which the ejection port M, which a label is ejected after printed therefrom in the portable printer 1, is provided; an upper cover 33 configured to open and close the upper part of the front surface of the portable printer 1; and a printer holder 35 that holds the portable printer 1 in the storage case 30. The printer holder 35 includes a pair of protrusions that protrude partially to the front side of the portable printer 1.
