Title: Method and apparatus for reading optical recording information
Inventor: KIMURA FUMIO
IPC: G11B7/09
Filed: 1985-05-18
Abstract: PURPOSE:To take out only the data of an intended data recording region from all the data read by scanning by detecting the reference lines to segment the intended data recording region. CONSTITUTION:A reading sensor 11 moves along the data recording region 3 on an optical recording medium C and reads the data by each one track. A reading position instructing means 70 counts the reference line detection signal Ls with a counter 71a, compares the count value thereof with a target value in a comparator 72a and detects the data recording region to be read. The target value is preset by a presetting function of an up-down counter 72b. A gate circuit 20 opens when a gate signal Gs is outputted. The binary coded signal Bs outputted from a reading means 10 is thereafter inputted to a decoder 30. The count value of the reference lines exceeds the target value when the next reference line is detected and therefore the comparator 72a stops the gate signal and only the data of the track of the intended data recording region is selectively inputted to a decoder 30.

Filed: 1978-08-31
Abstract: PURPOSE: To enable cleaning with a uniform pressure, by constituting so that the central part of the elastic cleaning blade may protrude from the both ends thereof.  
     CONSTITUTION: An elastic cleaning blade 2 abutting against a photosensitive drum 1 is supported by a holder 3. The holder 3 is secured to a shaft 4 which is fixed to a side plate of a casing, and a proper pressing force is applied to the cleaning blade 2 through rotation of the shaft 4.
