Abstract: PURPOSE:To facilitate a state of positioning with an eye to be inspected while enabling accurate positioning by providing a ring-shaped photodetecting sensor circumferentially outside a circular photodetecting sensor to detect the state of positioning with the eye to be inspected based on outputs of both the sensors. CONSTITUTION:Cornea Ec of an eye E to be inspected is subjected to a fixed cornea deformation by blowing air from a nozzle 7. An intensity of air which caused the fixed cornea deformation is measured with a pressure sensor 6 within a current blowing means 5 to be converted to an eye pressure. A light source 1 serves concurrently for detecting the cornea deformation and for positioning. The cornea Ec is irradiated with a luminous flux from the light source 1 through a lens 2 and the light reflectogaed from the cornea is received with a lens 3 to form a light source image on a photoelectric sensor 4. The photoelectric sensor 4 is provided adjoining on a circular center part element 41 and a ring- shaped peripheral part element 42 surrounding it to obtain an output independently. When positioning is proper, a reflection image 10 from the cornea of the light source 1 becomes almost the same in shape as the center element 41. The position of the image 10 is deviated vertical to an optical axis or in a direction of the optical axis and thus, it involves the peripheral element.

This control circuit stops the electric motor 13 of the crushing machine 7 after the lapse of time sufficient for the garbage in the crushing machine 7 to be discharged to the treating tank 16 and stops an electric motor 22 for rotating the treating tank 16 after a prescribed time from the operation stop of the motor 13. Further, the control circuit rotates the treating tank 16 for a specified time after a prescribed time since the motor 13 for rotating the crushing machine 7 stops. The control circuit rotates the treating tank 16 for the specified time after a prescribed time from the rotation stop of the treating tank 16. The state of not bringing the garbage into contact with the outdoor air and the state of bringing the garbage into contact therewith are repeated, thereby the decomposition by the treating medium of the garbage is accelerated.

Abstract: PROBLEM TO BE SOLVED: To quickly inspect comprehensive photo-sensitizing characteristics of a photoreceptor relating to almost all issues affecting an image by utilizing an electrostatic image on the surface of the photoreceptor, without using toner like an image toner method. SOLUTION: With an electric-optical crystal 3 indicating such characteristics as a reflectance factor changes according to changes in electric field applied to a crystal utilized, a bottom surface 3a is made to approach the surface of a photoreceptor 2, which is to be inspected so that the electric-optical crystal 3 is assigned, and a polarization light is projected toward the surface of the photoreceptor 2, as to converge on the bottom surface 3a of the electric-optical crystal 3, thus, based on changes in polarization light of reflection light from the electric-optical crystal 3, defects of the photoreceptor are detected.  Here, by utilizing the fact that changing condition in polarization direction is different based on the presence of defect on the photoreceptor 2 surface when the polarization light so projected as to converge on the bottom surface 3a is reflected, the presence of defect is judged based on changes in polarization in the reflection light.
