A register (20; 60) for a processing machine (1) for processing plate-like elements (10) includes a gripping element (21; 22) for placing the plate-like elements (10) in a gripper bar (31) of a conveyor (30) of a processing machine (1) conveying the plate-like elements (10) in a longitudinal direction, an actuator module (201, 202) to drive the gripping element (21; 22), at least one front correction sensor module (7) configured to measure the front position of register marks (12a) printed on a front section of the plate-like element (10) grasped by the gripping element (21; 22). The register (20; 60) includes at least one front pre-correction sensor module (80), placed upstream of the front correction sensor module (7) in the longitudinal direction, the front pre-correction sensor module (80) is configured: to detect the passage of a front transversel edge of the plate-like element (10) in at least two longitudinally spaced lateral axis of detection (P1, P2), one located in front of the other, and to provide measurements to a computation and control unit (40) of the processing machine (1) that is configured: to control the actuator module (201, 202) in order to move the gripping element (21; 22) toward the gripper bar (31) and to activate the gripping element (21; 22) in order to grasp a plate-like element (10). Also a processing machine for processing plate-like elements includes the register. A method for placing plate-like elements within a processing machine is disclosed.

An image forming apparatus including: a sheet feeding tray configured to support a sheet; and an apparatus main body configured to support the sheet feeding tray so as to be moveable in a direction parallel with a sheet feeding direction, the apparatus main body including a chute configured to guide the sheet that is fed from the sheet feeding tray, wherein the sheet feeding tray includes a guiding member configured to be displaced between an engaging position at which the guiding member engages with the chute and restrains movement of the sheet feeding tray and a separation position at which the guiding member separates from the chute and permits movement of the sheet feeding tray, and wherein the guiding member is configured to guide the sheet that is fed from the sheet feeding tray toward the chute when the guiding member is located at the engaging position.

A sheet feeder includes a controller configured to control an emitter to emit an ultrasonic wave toward a target sheet being fed along a sheet guide, control a measurer to measure a first reception intensity of a first component of the ultrasonic wave received by a receiver during a first period of time, control the measurer to measure a second reception intensity of a second component of the ultrasonic wave received by the receiver during a second period of time, and determine a feeding state of the target sheet in a detectable area between the emitter and the receiver within the sheet guide, based on the first reception intensity and the second reception intensity.

A printer includes a first housing part, a second housing part, a printing part that prints on the first paper sheet and the second paper sheet, a conveying part that includes a holding part that is configured to hold the overlapping first paper sheet and the second paper sheet respectively pulled out from a first paper roll and a second paper roll, and conveys the first paper sheet out of the first paper sheet and the second paper sheet held by the holding part to the printing part, a first paper sheet sensor that detects the presence of the first paper sheet, and a controlling part that makes the conveying part convey the second paper sheet held by the holding part to the printing part when the first paper sheet sensor detects that there is no first paper sheet to be conveyed to the printing part.

For the purpose of delivering a laundry item (10) to an ironer, the laundry item (10) is spread, by opposite corners of a lateral edge (20), by means of spreader clips (18, 19). In this case, deformations, or ear formation may occur at the corner regions (12, 13) of the laundry item (10) that are gripped by the spreader clips (18, 19). This ear formation is mostly irreversible, and in the long term results in damage to the laundry items (10). The invention creates a method and a device by which the laundry item (10) is delivered to an ironer in a gentle manner. For this purpose, at least one corner region (12, 13) of the laundry item (10) that is gripped by a spreader clip (18, 19) is captured by an imaging means as the laundry item (10) is being spread.
