20130101309 | BLOWING DEVICE AND IMAGE FORMING APPARATUS - A blowing device includes a blower and an air duct including an inlet, an outlet, and a body. The outlet faces a longitudinal portion of an oblong target structure toward which air is blown. The outlet allows air to be discharged in a direction that is substantially perpendicular to a longitudinal direction in which the longitudinal portion extends. The inlet has an opening and the outlet has an oblong opening, and the opening of the inlet and the opening of the outlet having different shapes. The body has a passage space formed therein. Plural restraining portions that restrain airflow are disposed at different positions in the passage space in the direction of airflow. A most downstream one of the restraining portions is formed so as to at least partially cover the passage space with an air-permeable member having plural air passage portions that are distributed the air-permeable member. | 04-25-2013 |
20130153764 | AIR SUPPLY TUBE, AIR SUPPLY DEVICE, AND IMAGE FORMING APPARATUS - Provided is an air supply tube including an inlet port that takes in air, an outlet port that is arranged opposite a portion of an elongated target structure in a longitudinal direction, to which air taken in from the inlet port is to be supplied, and has an elongated opening shape, a channel portion in which a channel space for allowing air to flow between the inlet port and the outlet port is formed, and plural suppressing portions that suppress the flow of air, wherein the plural suppressing portions include at least a most downstream suppressing portion, a first upstream suppressing portion that is provided in a part initially located on the upstream side in the air flow direction, and a gap regulating portion that forms an extended gap at the same interval. | 06-20-2013 |
20130165036 | BLOWER PIPE, BLOWING DEVICE, AND IMAGE FORMING APPARATUS - Provided is a blower pipe with an inlet, an outlet, a passage part formed with a passage space to cause air to flow therein, and suppressing parts that are provided in different parts in a direction in which air in the passage space of the passage part is caused to flow and that suppress the flow of the air, wherein an outlet suppressing part constructed so that the passage space in the outlet is closed by a permeable member dotted with ventilation portions is provided in the outlet of the passage part as one of the suppressing parts, and wherein the permeability of an end region present at least at one end in the lateral direction orthogonal to the longitudinal direction among regions along the longitudinal direction of the opening shape of the outlet is set to a smaller value than the permeability of regions other than the end region. | 06-27-2013 |
20140119767 | BLOWER PIPE, BLOWING DEVICE, AND IMAGE FORMING APPARATUS - A blower pipe includes an inlet port, an outlet port, a flow path that connects the inlet port and the outlet port and is bent at least in one location, and plural flow control members that are provided in mutually different regions in a direction in which air in the flow path is caused to flow and that control the flow of the air, wherein a flow control member of the plural flow control members closest to the inlet port (a) cuts off a portion of a bent portion of the flow path while air crossing the portion, (b) makes an elongated gap to pass air, and (c) satisfies following condition; when a virtual straight line which passes through both end portions of the elongated gap is drawn, the virtual straight line lies downstream of an extension line of a wall immediately before the flow path is bent. | 05-01-2014 |
20140140718 | BLOWING TARGET STRUCTURE, AND IMAGE FORMING APPARATUS - A blowing target structure includes an opening portion that (a) is an inlet into which the air flow from a blower pipe that has an elongated shape in one direction, (b) is elongated in the same direction as the one direction of an outlet of the blower pipe, (c) has a member that is provided at least on one end side in a lateral direction orthogonal to a longitudinal direction of the opening portion to set an air permeability of a member side region of the opening portion to a value smaller than an air permeability of a region other than the member side region of the opening portion. | 05-22-2014 |
20140169825 | BLOWER PIPE, BLOWING DEVICE, AND IMAGE FORMING APPARATUS - A blower pipe includes an inlet port, an outlet port, a flow path that connects the inlet port and the outlet port to cause air to flow therethrough and that are divided by a partition wall, and plural flow control members that are respectively provided in different parts in an air flow direction in each of divided passage spaces that are divided by the partition wall and that control the flow of the air, wherein the inlet port and the outlet port are constituted by plural opening portions, respectively, the plural opening portions that constitute the outlet port have elongated opening shapes divided by the partition wall, and a flow control member of the plural flow control members closest to the inlet port is provided in the vicinity of the bent portion. | 06-19-2014 |
20140169832 | CORONA DISCHARGER, AND IMAGE FORMING APPARATUS - A corona discharger includes a discharge wire, and a surrounding member, that is provided with an opening portion which is an entrance of an air flow, that faces a surface of a member to be charged that rotates around a rotational axis of the member to be charged, that is arranged with a gap from the surface to be charged, and that surrounds the discharge wire in the direction of the rotational axis, wherein the opening portion is provided at a part of the surrounding member located on the upstream side of the discharge wire in a rotational direction of the member to be charged with the discharge wire. | 06-19-2014 |
20140294580 | BLOWING DEVICE, AND IMAGE FORMING APPARATUS - Provided is a blowing device including a blower that sends air, a blower pipe having an inlet that takes in the air sent from the blower, an outlet that is formed in an elongated opening shape parallel to the portion of the target structure in the longitudinal direction, and a body portion that connects the inlet and the outlet and to cause the air to flow therethrough, and plural flow dividing plates, each of the flow dividing plates having a distributing portion and a changing portion. | 10-02-2014 |
