Title: Diaphragm device of electronic still camera
Inventor: HAYASHI HIDEKAZU
IPC: G03B9/04
Filed: 1993-10-12
Abstract: PURPOSE:To prevent smear and fricker in a frame photographing by positioning a pair of shield plates at a location covering an opening part after a photographing is terminated and to enable the reduction of diaphragm plate because a turret diaphragm plate is not provided with a light shielding part. CONSTITUTION:Shield plates 44 and 46 overlap with each other, cover an opening part 36, apart from each other and open the opening part 36. A moving means 11 moves the shield plates 44 and 46 to a location where the opening part 36 is opened during the electric charge storage time of a solid-state image pickup element and moves the shield plates 44 and 46 to a location where the opening part 36 is covered after the electric charge storage time of the solid- state image pickup element is terminated. When selected diaphragm holes 24 to 34 of a turret diaphragm plate 10 are positioned at the opening part 36 of the solid-state image pickup element at the time of a photographing, the shield plates 44 and 46 are separated with each other and are positioned at the location where the opening part 36 is opened. After the photographing, the shield plates 44 and 46 overlap with each other and are positioned at the location covering the opening part 36.

Filed: 1990-09-25
Abstract: PURPOSE:To prevent the leakage of powder smoke occurring when toner is replenished by providing a vent hole on a toner holding part and attaching a filtering member on the vent hole. CONSTITUTION:The vent hole is provided on a side surface part in the vicinity of the toner replenishing part 5 of a toner holding part 4, and the filtering member 7 is attached to the vent hole. On the other hand, an opening part 6 for replenishing the toner is provided on the lower part of the toner replenishing part 5, the opening part 6 is in a closed state before the toner is replenished, and the toner 2 is held inside. When the toner is replenished, the opening part 6 is closed to replenish the toner 2 to the toner holding part 4, while being adhered to the toner replenishing part 5 of a developing unit 1 to keep the degree of closing. At such a time, the pressure fluctuation of internal air accompanied with the movement of the toner 2 occur inside a toner holding part 4, but the air is ventilated in the filtering member 7, shown by the arrow A, and a pressure difference is mitigated. Thus, the powder smoke 8 itself is prevented from being leaked outside by the filtering member 7.

CONSTITUTION:The optical system 5 for changing the incident direction of the exciting light 6 makes the exciting light 6 incident perpendicularly to the microplate by deviating the optical system 5 from the optical path of the exciting light 6 at the time of making transmission and absorption measurement. On the other hand, the optical system 5 to change the incident direction of the exciting light 6 is inserted into the optical path of the exciting light 6 at the time of making fluorescent measurement. The incident direction of the exciting light 6 is made into the direction diagonal with the microplate and the exciting light 6 is no longer made incident to the detector 10 by inserting this optical system 5. The fluorescence 24 is released in the direction of the detector 10 as well as against this and, therefore, the fluorescence 24 is made incident to the detector 10 and is received therein. The transmitted fluorescence is measured in the state of the high S/N in this way.
