Title: Clock synchronization system
Inventor: MARK L WITSAMAN
IPC: G04G7/02
Filed: 1993-03-30
Granted: 1999-10-01
Abstract: A clock synchronization system for synchronizing the performance of a number of clocks (46) so that they run parallel with a reference clock is disclosed. Each clock of this synchronization system includes a counter (52) that indicates the current time and that is sequentially incremented by a counter advance signal applied thereto. A time counter controller (54) both initializes the counter and generates the clocking signal that controls the advancement of the counter. The time counter controller further monitors the time indicated by the counter and compares it to a reference-time signal received from a reference clock. Based on the comparison, the time counter controller selectively reinitializes the counter and adjusts the rate at which the clocking signal is applied to the counter so as to ensure that the counter advances at a rate equal to the rate at which the reference clock advances. In some versions of the invention, the comparison of the reference-time signal to the actual clock counter time is made at a maintenance operation point (58) remote from the clock. In these versions of the invention, the maintenance operation point reports the difference in the two times back to the time counter controller, which, in turn, makes the appropriate adjustments to the counter and to the clocking signal. <IMAGE>

When fixing the optical scanning unit(10) to the optical scanning unit support on the machines main body to support the light source(12), rotating polyhedron mirror(14), and reflector(16), make only three attachment locations in a triangular shape in order not to form a diagonal line by locking means(18) such as screw, welding, or riveting. Even though the three locking position are triangularly speed, the line between locking positions is not crossed by rotating polyhedron mirror(14), the principal part of optical scanning unit(10), to prevent transformation of optical scanning unit(10) and reduce optical scanning functioning errors.
