IPC: G03G13/26
Filed: 1995-06-20
Abstract: PURPOSE: To inexpensively obtain an image having multilevel gradation in dot by changing exposure according to the gradation of image information when a simultaneous developing and exposure action is executed. CONSTITUTION: A photoreceptor 1 is constituted of such structure that a transparent electrical conductive layer is provided on a transparent substrate and a photoreceptive layer is provided thereon besides. Then, a developing electrode 2 and a squeezing roller 6 are arranged by leaving a fixed distance between the photoreceptor so that liquid developer is continuously supplied between them, held and recovered. The electrical conductive layer of the photoreceptor 1 is grounded and a developing bias voltage is impressed on the electrode 2. In accordance with the movement of the photoreceptor 1, the back surface thereof is irradiated with light having the image information. Then, the exposed photoreceptor 1 becomes electrically conductive and electric charge is moved according to bias potential. In such a case, the multilevel gradation is realized in dot by changing the intensity of the light with which the photoreceptor 1 is irradiated.

Abstract: PURPOSE:To efficiently mold and supply a spiral lid by a method wherein each upper disk is held on a turret by intermittent rotation of the turret so that it is moved to a working position opposite to a lower disk and a supply position where a spiral lid is supplied to a conveyer. CONSTITUTION:A turret 32 drops to have an upper disk 31 lowered while an elevator 19 rises to have a sheet material clamped by the upper disk 31 and a lower disk 17 and interposed between upper and lower plates 25, 29, causing a circular blade 24 to punch the sheet material in a circle. Then, the lower disk 17 is rotated with the upper disk 31 rotated subsequently, so that a clamp portion of the upper and lower disks of a sheet material 23 also rotates. Although a sheet material outside the clamp portion is to rotate at this time, since this portion comes contact with upper and lower protrusions 15A, 29A and pushed between the protrusions, it is interrupted from rotating and included inward to have a spiral lid 3 molded. After this, the spiral lid 3 is vacuum- sucked onto the upper disk 31, and the turret 32 rises to have it moved onto a conveyer 10.
