Title: Optical disk recorder
Inventor: ISHII KOICHIRO
IPC: G11B7/004
Filed: 1996-03-07
Abstract: PURPOSE: To shorten the time required for recording operation without reducing reliability of the recorded data by detecting a reflection light quantity from an optical disk when the data are recorded or erased, comparing it with a reference value and performing verification operation only in the case of exceeding a proper range. CONSTITUTION: When the data are recorded on the optical disk 7, when the old data are written beforehand on the area to be required so as to record the new data, the old data are erased temporarily. A level V of an output signal from a foreign matter detecting photodetector 17 while erase operating and the level Vref of a prescribed reference signal are obtained, and the V is compared with the Vref . When the V fails below the Vref always while erase operating, no verification operation is performed, and recording operation is performed instantly after erase operation is ended. When the output signal level V from the foreign matter detecting photodetector 17 exceeds the level Vref even one time while erase operating, the recording operation is performed after the erase operation is ended, and thereafter, the verification operation is performed.

Abstract: PROBLEM TO BE SOLVED: To prevent ink from leaking out of a pump housing. SOLUTION: When a first piston member 53 moves an ink W dropping in a pump housing from a suction hole 52a to an opening end 52c, it pushes the ink to an ink reservoir groove 52d. In a condition that the suction 52a is closed by a second piston member 54, a pump chamber 52e formed between both of the piston member 53, 54 is coupled to the ink reservoir groove 52d. In this condition, both of the piston members 53, 54 are relatively moved to suck the ink in the ink reservoir groove 52d into the pump chamber 52e. The pump 52e and ink reservoir groove 52d are decoupled from each other and a regular suction operation from the suction hole 52a is started. As a result, the ink is discharged along with ink from a printing head.
