摘要： An image forming apparatus includes: an exposure head including a light emitting portion that includes a first electrode layer including a plurality of electrodes that are two-dimensionally arranged in a main scanning direction and a sub-scanning direction, a light emitting layer stacked on the first electrode layer, and a second electrode layer through which light is transmissible; and a controller configured to control a voltage applied to each of the plurality of electrodes in such a way that the light emitting layer emits light, in which the plurality of electrodes for forming an identical pixel are arranged in such a way that the electrodes partially overlap each other when viewed from the rotation direction, and an inter-centroid distance of the plurality of electrodes in the rotational axis direction is equal in the rotational axis direction, and d3 = W1/n (n is a natural number of 2 or more), in which W1 [mm] is a width of the electrode in the rotational axis direction, n is the number of electrodes for forming the identical pixel, and d3 [mm] is the equal inter-centroid distance in the rotational axis direction.

摘要： A light-emitting device includes a first connection wire and a second connection wire each connecting a first power supply wire and a second power supply wire, a second lead wire between the first connection wire and the second connection wire, and first lead wires including a first lead wire located opposite to the second lead wire from the first connection wire. The first lead wires are parallel to one another and include first connection pads as first connections at ends connected to first signal wires. The second lead wire includes a second connection pad as a second connection at an end connected to a second signal wire. A distance between the second connection pad and a first connection pad of the first connection pads adjacent to the second connection pad is greater than a distance between adjacent ones of the first connection pads.

摘要： A pulse signal is detected from an encoder signal of a rotary encoder. The detected pulse signal is used as a signal for controlling a light exposure timing of a line type light exposure head (25) and is used for detecting a transport speed of an instant film. The light exposure head (25) sequentially performs light exposure for a line image on the transported instant film in synchronization with each pulse signal detected from the encoder signal, and a density correction unit (47a) corrects an amount of light emission of the light exposure head (25) depending on the transport speed of the instant film.

摘要： The invention describes a laser printing system (100) for illuminating an object (70) in a working plane (80). The object (70) moves relative to a print head (50) of the laser printing system (100). The print head (50) comprises a total number of laser modules (150), each laser module (150) comprises at least one laser array (110) of lasers (115). At least two of the laser modules (150) share an electrical power supply (20). The laser printing system (100) further comprises a controller (10) being adapted such that at maximum processing speed of the print head (50) only a predefined number of laser modules (150) can be driven at nominal electrical power, wherein the predefined number of laser modules (150) is smaller than the total number of laser modules. The invention further relates to a corresponding method of laser printing. The laser printing system and the method allow designing the laser printing system for, for example, only 20% of the total power which would be required to drive all lasers at nominal electrical power while having only slightly reduced processing speed.
