4) in the discharge
Load under the completion status, by on/off key, drive motor will drive to the outside direction in CD cabin, and pushes CD to CD portion out of my cabin.This state is exactly ' in the discharge ' state.
' in the discharge ' state and above-mentioned ' in the loading ' state, its signal of sensor is identical, is to discern ' in the discharge ' state and ' in the loading ' state according to output signal only therefore.Here, under the irrelevant prerequisite of sensor output signal, drive motor drives to the outside direction in CD cabin, just compact disc states is judged as ' in the discharge ' state.
5) discharge is finished
' discharge is finished ' state refers to the state that CD is discharged in the CD cabin fully.Among Fig. 2, drawing symbol 6 expression be the 1st CD position after the discharge of the 1st CD is finished, and 7 expressions of drawing symbol is the 2nd CD position after the discharge of the 2nd CD is finished.As shown in Figure 2, under the discharge completion status of the 1st CD, the output signal of CD induction pick-up is ' height ', and the 1st CD discharges signal of sensor and the 2nd CD discharge signal of sensor then is ' low '.Under the discharge completion status of the 2nd CD, it is ' height ' that the output signal of CD induction pick-up and above-mentioned the 1st CD are discharged signal of sensor, and above-mentioned the 2nd CD discharge signal of sensor is ' low '.In addition, after discharge was finished, the work of drive motor will stop.
6) emergency
Load switch and be in the OFF state, and under the idle state of drive motor, CD is not to be in to load to finish and when discharging the completing place, just be judged as the emergency state.In other words, load switch and be in the OFF state, and after drive motor quits work, the sensor (CD induction pick-up, the 1st CD are discharged sensor, the 2nd CD is discharged sensor) when exporting the signal outside (L, L, L), (H, L, the L) or (H, H, L), just is judged as the emergency state to the state of CD.
The same in the arrangement for loading optical disk CD cabin among the present invention with prior art, be provided with CD induction pick-up 1.But CD induction pick-up 1 and the CD induction pick-up 1 shown in Fig. 1 being provided with on the part in the CD cabin is different among the present invention.In other words, the CD induction pick-up 1 among Fig. 1 is arranged on the central authorities of lower end, CD cabin, and the CD induction pick-up 1 among the present invention is arranged on the position of departing from CD cabin lower end central authorities then as shown in Figure 2.
As shown in Figure 1, when the CD induction pick-up was arranged on lower end, CD cabin middle position, if the 1st CD (8cm CD) is discharged fully, the CD induction pick-up will enter into the clamping region (zone between cd-rom recording surface and the CD hole) of the 1st CD.According to the kind of the 1st CD, can be divided into clamping region transparent with opaque dissimilar; If the clamping region of the 1st CD adopts transparent type, the output signal of CD induction pick-up is ' low '.At this moment, for the 1st CD is extracted from slot, with pulling the 1st CD, the CD induction pick-up will be exported ' height ' signal, and the drive motor that starts simultaneously in the CD cabin spurs the 1st CD.
Therefore, when the 1st CD is discharged and to be finished, be not in the clamping region of the 1st CD, as Fig. 2, break away from lower end, CD cabin middle position, the CD induction pick-up is set at the position of skew to the left in order to ensure the CD induction pick-up; Like this, in the process that the 1st CD is taken out from slot, the CD induction pick-up is exported ' height ' signal all the time.
