摘要:
The present invention relates to an organic EL light emitting element that can suppress deterioration of a light emitting layer and can provide a high light-emission intensity. This organic EL light emitting element includes a light emitting part and a rectifier part connected in series to the light emitting part. Both of the light emitting and rectifier parts include organic thin layers. The electrostatic capacity of the rectifier part is smaller than that of the light emitting part.

An image forming apparatus includes a first and a second image forming sections, a paper feeding section, and a paper output section. The image forming sections form an image on paper independently. The apparatus is laterally dividable into a first and a second portions where the first and second image forming sections are respectively positioned. The feeding section is arranged below the first image forming section in the first portion. The output section is arranged above the second image forming section in the second portion. The apparatus has two simple transport paths that run vertically through the image forming sections, respectively, without intersecting each other and detouring around the second or first image forming section.

An image on a fed document is read, and recording paper on which an output image is formed based on the read image is discharged onto a first tray. When overlapped feeding is detected at the time of feeding a document, page numbers of the overlapped documents are recorded, and an image on a document fed after the overlapped documents is read, an output image is formed on recording paper based on the read image, and the recording paper is discharged onto a second tray to notify the occurrence of overlapped feeding. When the documents are set again by the user and fed, an image on a document of a page number matching a recorded page number is read, an output image is formed on recording paper based on the read image, and the recording paper is discharged onto the first tray.

A digital audio player in which the pieces of music are played according to a program. The program is selected so that the total playing time does not exceed a set period of time. The selection is performed by reading playing times from a disk on which are recorded both the pieces of music and their separate playing times.

A drive unit which can prevent the decrease of the luminance of a self-luminous device due to degradation or a change is electric characteristic thereof. The drive unit has a semiconductor device having an electric characteristic almost the same as the that of the self-luminous device, and drives the semiconductor device in accordance with the frequency of light emission of the self-luminous device. The device generates a characteristic change detection signal indicating the degree of a change in an electric characteristic of the semiconductor device, and supplies the self-luminous device with a drive signal having a current level or a voltage level based on the characteristic change detection signal.
