Title: Copying machine
Inventor: MASUDA SHIYUNICHI
IPC: G03G21/00
Filed: 1978-10-15
Abstract: PURPOSE: To increase the controllability of the copying machine, by displaying the original replaceable period with action signal of a switch which opens and closes in cooperation with the original holding member, and timing signal at the end of exposure.  
     CONSTITUTION: When the original is placed on the platen and the original holding member is closed, the output Sg of a microswitch which cooperates therewith becomes low level, so that FF Q 5  is not reset. In this state, when copying of specified number of sheets is over, and a count-up signal CUT and a reverse signal when the original platen moves backward at the end of exposure are inverted to high level, the FF Q 5  is set through AND gates Q 2 , Q 3 , and an AND gate Q 6  is opened by the set output of FF Q 5 , so that a transistor Q 7  is made to conduct depending on the oscillation output of an oscillating circuit 4, thereby lighting up the lamp 24 only when the original is to be replaced. Therefore, negligence of replacement of the original may be prevented, and the timing for replacement of the original may be confirmed, thus contributing to the controllability of the copying machine.

IPC: G01N21/55
Filed: 1988-05-25
Abstract: PURPOSE:To exactly measure a disk reflectivity and a film reflectivity by executing a calibration of a measuring system by using a standard sample having no reflection preventive film which has been labelled so as to show a reflectivity of a reflecting film, before executing a measuring operation. CONSTITUTION:The surface on which a laser light is made incident is labelled by using parallel rays, by using a standard sample 5 on which a reflection preventive film 52 has been formed. Subsequently, by using the sample 5 having the preventive film 52, a calibration of a measuring system is executed. In this case, since the sample 5 executes no surface reflection, a laser light P0 irradiating through an objective lens 32 all reaches a reflecting film 51, and its reflected light Pr is detected by a photodetector. Therefore, a calibration curve which has been obtained by a calibrating operation becomes that which corresponds to a state of the time when the emitted light P0 has all reached the reflecting film 51. In such a way, when a reflectivity of an optical disk 1 is measured by using the measuring system which has been calibrated, the light P0 which has been emitted from the objective lens 32 reaches a recording film 11 after having been influenced by a surface reflection of the optical disk 1, and magnitude of the reflected light Pr is detected by the photodetector.
