Abstract: A control system for collectively supervising a plurality of copiers or similar image forming apparatuses connected to a control device by communication lines with or without the intermediary of communication control units. To down-load data relating to image formation, the control device determines whether or not a copier of interest is in an inoperative state and, if it is in an inoperative state, automatically sends the data to the copier via a telephone line, an exchange, and a communication control unit. This data is written to storing means built in the copier. To up-load data relating to image formation, the control device causes each copier to automatically send the data stored in the storing means and stores the data in memory means. Up-loading is effected at an optimal time other than the time when the copier is performing an automatic adjustment, is in use, or is quite likely to be used.

Abstract: A color cathode-ray tube where an electron beam selection mask with an aperture grille type beam selection electrode of a thin metal plate attached to a frame is supported by engagement of stud pins with support springs and is thereby positioned stably opposite to a color luminescent screen formed on the inner surface of a panel. A projection is formed on either the top of each stud pin or the bottom of each cap opposed thereto, while a recess is formed in the other for engagement with the projection in the direction orthogonal to the action of the support spring. The mutual contact portions of such projection and recess are coated with solid lubricant films so that the beam selection mask can be reset at its proper position despite any external impact applied thereto.
