An image forming device includes a printer engine, a display unit, and a sound reproducing unit. The image forming device receives a list of contents from a content distributing device, and has the display unit display the content list. From the content list displayed by the display unit, a user of the image forming device selects a print content, a display content, and a sound content that he desires, associates the selected contents with one another to produce a group of the selected contents, and requests the content distributing device to distribute the group of the selected contents. The content distributing device produces the group of contents associated with one another, and distributes the group of contents to the image forming device. The image forming device expands the print content in the distributed content group into print data, and has the printer engine print the print data. In synchronization with printing of the print data, the display unit displays the display content associated with the print content, and the sound reproducing unit reproduces the sound content.

An electronic paper having a display unit formed of a flexible sheet. The electronic paper comprises the display unit composed of a light-emitting device and a switching device and a drive unit composed of a drive circuit disposed at one edge of the display unit. The light-emitting device and the switching device both operate at low operating frequencies and are made of a flexible organic semiconductor. Since the hardness of the drive unit can be high, a semiconductor device having a high operating frequency such as a C-MOS is provided to the drive unit. Though the switching time is relatively long, the data setting time can be short. As a result, a sharp image can be produced.

An image formation and control method and apparatus enabling a user to print data to be printed reliably up to the limited reproduction number permitted to the user even if troubles at the time of printing occur when the number of reproductions of the data to be printed is limited, is presented. With reference to the printing management information added to the data to be printed, when the number of reproductions of the data to be printed is limited, the mode is changed from the performance priority mode for normally reproducing data to be printed into the safety priority mode capable of carrying out the required reproduction more reliably than in the performance priority mode, the number of printing of the data to be printed is managed as a printing history, and the printing of the data to be printed is controlled based on the number of reproductions of the data to be printed and the managed printing history.

A galvano-mirror recorder for moving the light beam in a circular pattern applied to a disk is rotated by a driving circuit. A track error signal is obtained from an output of a photosensor for detecting a deviation of a light beam applied position from a track on the disk. To detect a rotation angle when rotating the galvano-mirror recorder with a photosensor and cancel an offset generated due to rotation of the galvano-mirror recorder in accordance with the detected rotation angle, a differential amplifier for correcting the track error signal is used to correct the offset of the track error signal due to rotation.Moreover, in the case of retrieval of the tracks on the disk, the output of a phase compensation circuit for phase-compensating the sum of the output of a low-pass filter in accordance with the output of the photosensor and the output of a DC cut filter in accordance with the output of the photosensor is returned to the negative input terminal for driving the galvano-mirror recorder to lock the galvano-mirror recorder so that the center of a light spot is aligned with the center of the optical axis of an optical system even if a disturbance occurs.
