Filed: 1984-10-16
Abstract: PURPOSE:To give plural degrees of resolution to a solid-state image pickup element by connecting a sub-photosensitive element to a photosensitive element through a gate and opening and closing the gate separately from opening and closing of a transfer gate. CONSTITUTION:When the optical image of a subject is formed on the image pickup face of a solid-state image pickup element 15, a charge corresponding to the intensity of respective incident light is accumulated in each photosensitive element 1 and sub-photosensitive element 11. When a signal Sa of high level is given to an interlacing circuit 10, and then a signal Sb of high level is given directly after closing of a shutter, video signals for A field and B field having the size corresponding to charge accumulated in the element 1 are obtained in a terminal 5. When a signal Sc of high level is given to a terminal 14 next, a sub-vertical transfer gate 12 is turned on and becomes a potential equal to the element 1 corresponding to the element 11. Video signals of A', C' field are obtained similarly, and the degree of resolution becomes double. If a signal Sc of normally high level is given to the terminal 14, the elements 1 and 11 become one photosensitive element, and the degree of resolution becomes 1/2 of conventional values.

Filed: 1982-12-10
Abstract: PURPOSE:To read stably a mark without the influence of the thickness of a sheet and extend the life of a head by providing plural blocks pressing the sheet to the head by utilizing the expanding force of a spring and constituting the block with materials having a light reflection factor approximating that of the sheet. CONSTITUTION:The head 2 and supports 5 are fixed, and the supports 5 are fixed by spring fixing metal fixture 6 by the number of spring 4. Consequently, a group of blocks 3 is pressed with weak force to the lower surface of the head 2 with a shaft 7 as a fulcrum. When one of sheets 1 piled up in a hopper part is separated and is carried and is rushed to the head 2, the group of blocks 3 falls with the shaft 7 as the fulcrum. When the sheet 1 passes through the head 2, the group of blocks 3 is brought into contact with the lower surface of the head 2 again. Consequently, though the group of blocks 3 and the group of springs 4 are moved vertically each time when the sheet 1 is carried, the extent of this movement corresponds to the thickness of the sheet 1; and the pressure of the spring 4 is several mg, and therefore, stable reading is performed to extend the life of the head.
