摘要:
A starting unit starts, in parallel with a blowing operation for a first tray, a blowing operation for a second tray that is to perform a feeding operation next. When a predetermined time elapses after starting the blowing operation for the second tray, a feeding unit switches from the first tray to the second tray, and feeds the recording medium from the second tray. When the blowing operation is performed for a number of trays before switching the trays and the number of trays is equal to or larger than a predetermined number, a control unit limits the number of trays for performing the blowing operation.

A telephone service method and apparatus for providing a business advertisement to a caller of a telephone, comprising receiving a request for line connection from a phone of a caller, determining an identifier of the phone of a called party for which line connection is requested, judging whether the identifier of the called party is registered in a management table linking called party identifiers and business advertisements, and, when judging that the identifier of the called party is registered, sending a business advertisement linked with that identifier from business advertisements stored in a content database to the phone of the caller.

A belt device for an image forming apparatus includes an endless belt member supported at roller members, side frames disposed along sides of the belt member being respectively slidably supported at slide rails disposed at a body of the image forming apparatus, a rear frame constructed across the side frames, rotatably supporting shafts of the roller members at the rear side, a front frame rotatably supporting shafts of the roller members at the front side, and having a projecting surface smaller than an inner periphery of the belt member, and a support frame cantilever-supporting the front frame with respect to the rear frame. The rear frame includes a freely detachable holding member supporting rear side bearings supporting the rear side shafts of support rollers supporting the belt and a sub-bearing which is more to the center side in an axial direction of the support rollers than the rear side bearing.

A control unit calculates a difference between a displacement of a belt detected by an encoder and a predetermined target value, calculates a pulse frequency of a driving pulse signal based on a feedback control based on the difference and a feed-forward control based on a reference driving pulse frequency, sets a control range of the feedback control to be equal to or smaller than a frequency of one rotation of a driven roller, and controls driving of a pulse motor such that the belt moves at a constant speed.

A nonwoven fabric 10 has a first layer 1 containing crimped fibers 11. In the layer 1, the crimped fibers gather in parts to form a large number of fiber clusters 12 that are distributed all over the layer 1. The clusters 12 interconnect to each other to form a network structure in the layer 1. The nonwoven fabric 10 further has another fiber layer as a second layer 2 disposed on a side of the first layer 1. The two layers are partly joined at a large number of joints 3. The second layer 2 protrudes outwardly between the joints 3 to form a large number of protrusions 20.

A belt conveying device includes an endless belt stretched by a plurality of rollers; a drive unit that is connected to one of the plurality of rollers and drives the roller; a plurality of belt velocity detectors that are arranged at a plurality of locations along a belt width direction perpendicular to a moving direction of the endless belt and detect conveyance velocities of the endless belt; and a belt-inclination calculating unit that calculates an inclination of the endless belt in the moving direction from a difference between conveyance velocities of the endless belt detected by the plurality of belt velocity detectors.

A belt meandering preventing device includes a belt displacement detection unit detecting the amount of displacement in a belt width direction of an endless belt rotatably stretched over support parts; and a belt meandering correction unit correcting the displacement in the belt width direction of the endless belt based on the amount of displacement detected by the belt displacement detection unit. The belt displacement detection unit includes a moving part moving in association with the displacement of the endless belt or an edge of the endless belt in the belt width direction and optical sensors outputting signals with output levels corresponding to the proportions of the moving part in optical paths of the optical sensors. The optical sensors are arranged such that the output levels of the optical sensors change as the endless belt is displaced in the belt width direction in a predetermined high-resolution detection range.

A belt device for an image forming apparatus includes an endless belt member supported at roller members, side frames disposed along sides of the belt member being respectively slidably supported at slide rails disposed at a body of the image forming apparatus, a rear frame constructed accross the side frames, rotatably supporting shafts of the roller members at the rear side, a front frame rotatably supporting shafts of the roller members at the front side, and having a projecting surface smaller that an inner periphery of the belt member, and a support frame cantilever-supporting the front frame with respect to the rear frame. The rear frame includes a freely detachable holding member supporting rear side bearings supporting the rear side shafts of support rollers supporting the belt and a sub-bearing which is more to the center side in an axial direction of the support rollers than the rear side bearing.
