Title: Optical reader
Inventor: TOGASHI MITSUHIRO
IPC: G11B11/10
Filed: 1990-06-19
Abstract: PURPOSE:To read a high density data by detecting a beat wave made by modulation of a diffraction grating and recorded information of an information medium with a photodetector after returning to an objective lens. CONSTITUTION:Detection light from a semiconductor laser 1 is converged by a lens L0 and modulated by the modulating diffraction grating 13 in its focus position and then converged on the information medium 7 by a lens L1. Its return light is transmitted via a lens L2 through a demodulating diffraction grating 16 in its focus position to be demodulated, and is converged by a lens L and then received and detected by a pin photodiode 10. A laser beam emitted from the semiconductor laser 1 is modulated by the modulating diffraction grating 13, and the beat wave is made by this modulated laser beam and an information pit P of the information medium 7. When a frequency of this beat wave is lower than a cut-off frequency of the objective lens, the beat wave in the return light can be transmitted by the lens L2. Since no information can be read out under such a circumstance, the beat wave is converged and demodulated by the demodulating diffraction grating 16 and then received and detected by the pin photodiode 10.

Filed: 1987-06-26
Abstract: PURPOSE:To reduce the number of times of operations by making it possible to exchange a discharged toner collecting container once whenever a toner supplying container is exchanged with N-number of times. CONSTITUTION:If the toner stored in the toner supplying container is all consumed, a toner completion detection part 13 transmits a toner completion signal 131 to a control part 11. The control part 11 transmits a toner supplying container exchange signal 111 which demands the exchange of the toner supplying container to a toner supplying container exchange indicator 121 and also counts the toner completion signals 131. When the counted number of the toner completion signals 131 reaches a previously set N (N means a natural number >=2), the control part 11 judges that the discharged toner collecting container is full of the discharged toner and it transmits a discharged toner collecting container exchange signal 112 which demands the exchange of the discharged toner collecting container to a discharged toner collecting container exchange indicator 122. Thus, the number of times of exchanging the discharged toner collecting container can be reduced.
