An image forming apparatus forming an image on a sheet, including: an exterior member movable with respect to an apparatus main body; a locking portion locking the exterior member to the apparatus main body such that the exterior member is not moved with respect to the apparatus main body; a display portion which is disposed on the exterior member and displays a state of the locking portion; and a light source turning on the display portion, in which the display portion includes a thin portion which is a part of the exterior member, has a thickness less than thicknesses of other portions of the exterior member, and transmits light from the light source.

A method for monitoring a texturing process for producing crimped threads is presented, in which a thread tension is measured continuously on the textured thread and in which the thread tension measuring signals are captured and analyzed continuously, at least in one time interval, characterized in that a sequence of the thread tension measuring signals occurring in the time interval is analyzed with a machine learning program for the early diagnosis of one of a plurality of fault sources.

Techniques involve texturing a synthetic thread. The thread is pulled off a feed bobbin, which is connected via the thread end thereof to a beginning of a thread of a reserve bobbin by way of a thread knot. In order to monitor the texturing, a thread tension of the thread is measured and analyzed in a measuring point. Additionally, measuring signals of the thread tension are analyzed at the measuring point using a machine learning program, in order to identify the thread knot. To this end, a device has a diagnostic unit, which interacts with the thread tension measuring device in such a way that the measuring signals of the thread tension can be analyzed by way of a machine learning program for identifying a thread knot.

Provided is a printing apparatus comprising: a discharging unit configured to convey and discharge print media; a tray configured to receive print media discharged in a first direction from the discharging unit; and a drive unit configured to move the tray in a second direction perpendicular to the first direction. In discharging print media, the tray is moved in the second direction to thereby receive the discharged print media at a plurality of different positions on the tray. The tray is movable to a take-out position being a position closer in the second direction to a take-out side where print media are taken out than any of the positions at which the tray receives the print media discharged from the discharging unit.

A printing apparatus can prevent a print medium from buckling during discharging. In a case in which the print conveyance speed determined by the print mode is higher than or equal to a specified speed, the print medium after printing is conveyed to a discharging tray at the print conveyance speed, and in a case in which the print conveyance speed determined by the print mode is lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.
