Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To improve the print picture quality. SOLUTION: A picture printer is provided with an exposure means EM and carrying rolls R1 and R2. The exposure means EM sets an exposure for each pixel on the basis of picture information of an inputted picture and exposes photographic paper 2 with respect to the whole of the picture in a direction crossing a photographic paper carrying direction and a part of the picture in the photographic paper carrying direction and successively switches picture parts to be exposed in accordance with movement of the carried photographic paper, thereby exposing the entire picture to be printed. Carrying rolls R1 and R2 are arranged on both sides of an exposure position EP in the photographic paper carrying direction and are switched to a press-contact state and a release state.  The exposure means EM executes correction processing to compensate the change of the exposure state due to the change of the carrying speed which is accompanied with switching between the press-contact state and the release state of carrying rolls R1 and R2.

Title: Multiferrule body structure
Inventor: KOMATSU MASAO
IPC: G02B6/36
Filed: 1989-10-18
Abstract: PURPOSE:To improve position matching accuracy for the connection of plural optical fibers to plural photoconductors by providing plural ferrule simplexes for single optical fiber by bringing adjacent ferrule simplexes into contact with each other so that respective shaft center can be set in parallel with each other in the same flat plane. CONSTITUTION:Such structure that the ferrule simplexes 40 are arranged so that their shaft center can be set in parallel on the same flat plane and they are brought into contact with each other is employed. Thereby, it follows that the deviation of the shaft center between each of the ferrule simplexes 40a-40d i.e. deviation between respective central axis (optical axis) when the terminal channel of the optical fiber is inserted fixedly to each of the ferrule simplexes 40a-40d depends on only the eccentric accuracy of the ferrule simplex 40. Since the eccentric accuracy is remarkably high, the maximum deviation quantity between the central axes by multiferrule can be remarkably reduced compared with that in a conventional system. Thereby, it is possible to remarkably improve the position matching accuracy for abutting connection when multiple number (multicore) of optical fibers is connected to the same number of another photoconductor.
