Abstract: An image forming apparatus includes a conveying section for withdrawing and conveying a printing medium stored in the form of a roll, a printing section for effecting a printing operation on the printing medium, a decurling device for correcting curling in the printing medium and a controlling section. The decurling device is disposed on the downstream side of the printing section. The controlling section controls such that a decurling operation to be effected before the printing operation and a decurling operation to be effected after the printing operation are effected by the decurling device.

Abstract: A photographic printing device includes an ink-jet printer with recording paper magazine. The recording paper magazine includes a housing and a humectant. The housing is configured to receive a recording paper. The humectant is provided in order to moisturize the inside of the housing of the magazine. The humectant is preferably placed at an upper portion of the magazine in order to allow efficient moisture transfer by way of natural convection.

Abstract: A printer forms an image on a print sheet drawn from a print sheet roll, with using a print head. A transport roller unit for drawing the print sheet from the roll and transporting it to the print head includes a drive roller for taking up the print sheet around a peripheral surface thereof for a predetermined distance in a transporting direction, with the printing face thereof being on the inner side, thus applying a transporting force thereto and an opposing portion for causing the print sheet into abutment against the peripheral surface of the drive roller.

Abstract: An automatic photo film feeding apparatus includes a transport mechanism for successively transporting a plurality of film cartridges to a feed position. Transport mechanism includes a first transport unit for supporting the film cartridges with photo films drawn downward and successively transporting film cartridges substantially horizontally to a transfer position, and a second transport unit for receiving film cartridges transported to the transfer position by the first transport unit, and transporting film cartridges horizontally to the feed position. Second transport unit has a posture change mechanism for changing film cartridges to a posture having photo films drawn from film cartridges being directed substantially horizontally. Feeding apparatus includes a feed mechanism for drawing photo films out of film cartridges transported to the feed position, and feeding photo films to a processing section.

Abstract: A rack which can completely expel air remaining in treating solution passages. The rack has a rack body formed with a downward feed path and an upward feed path. A rack plate is provided on the outer side of each feed path. Each plate has treating solution passages extending in a width direction of the plate, and nozzles for blowing treating solution fed into the treating solution passages into the feed paths. An air reservoir is formed in the longitudinal central portion of each treating solution passage. An air vent passage is connected to the top of each air reservoir. If there is any air remaining in the treating solution passages when the rack body is set, such air can be urged into the air reservoirs by treating solution flowing into the treating solution passages and expelled from the air vent passages.

Abstract: The present invention belongs to a technical field in the oxygen steel making, more particularly in the steel making by blowing oxygen into a converter from its top and bottom. The total amount of oxygen to be blown into a top and bottom blowing converter is substantially the same as that of oxygen to be blown into a bottom blowing converter, but a part of the total amount of the oxygen is blown into the converter from its top. Therefore, the injection capacity for lime powder is necessarily decreased corresponding to the decrease of the blow rate of the bottom blown oxygen, and the decrease of the injection capacity causes the initial stage blowing up, being generated often in the case where blowing of lime powder is not carried out in the bottom blowing.

Abstract: A device for pedaling a bicycle in a stationary state, for the purpose of physical training or bicycle testing. This device, a kind of bicycle stand, comprises a member for unmovably holding a front wheel of a bicycle and the other member for sustaining a pair of rollers on which a rear wheel of the bicycle is rotatably placed, said members being formed at or connected to both longitudinal ends respectively of a strip of plate, and a bicycle supporting frame extending vertically aslant in connection with the above-mentioned strip of plate, in the foregoing construction this device enabling a bicycle to be pedaled in a stationary state on this device and accordingly enabling the attainment of a physical training without going outdoors. This device also serves for stationary testing a bicycle for its running and/or braking efficiency.
