Abstract: A sheet feeding apparatus includes a sheet stacking portion for stacking a sheet, a sheet feeding roller for feeding the sheet stacked on said sheet stacking portion, a supporting member, rotatably supported by a base member, for rotatably supporting said sheet feeding roller, and a spring stretched between the base member and an acting portion of the supporting member. The acting portion of the supporting member is located downward with respect to a rotation center of the supporting member when a sheet stacking amount is small, and the acting portion of the supporting member is located upward with respect to a rotation center of the supporting member when a sheet stacking amount is large.

Abstract: This invention relates to an apparatus and method capable of appropriately preventing a printing medium from being diagonally conveyed upon feed regardless of changes in printing medium feed conditions. In this invention, the maximum output value of a PWM signal is compared with the sum of a predetermined bias value and the PWM signal when a sensor detects the tip of a fed printing medium. If the sum is smaller than the maximum output value, it is monitored that the value of the PWM signal increases by the bias value. If the sum is equal to or larger than the maximum output value, it is monitored that the conveyance speed of the printing medium becomes smaller than a predetermined threshold value. Control is performed on the basis of the monitor results to stop driving a DC motor that supplies a driving force to rollers used for feed and conveyance.

Abstract: A conveying device in which positional displacement of a sheet may occur due to, for example, backlash of a mechanical system is provided. In the conveying device, when the speed of an encoder is decelerated to a predetermined speed after an edge of a sheet abuts against a roller during conveyance of the sheet, an encoder position is obtained. After the roller stops due to the backlash, an encoder position is obtained again. An amount of conveyance of the sheet to a print start position is corrected on the basis of the two encoder positions that have been obtained.

Abstract: A sheet feeding apparatus includes a sheet stacking portion for stacking thereon a sheet, a sheet feeding portion for axially supporting a sheet feeding roller, and a spring portion actable on the sheet feeding portion. The spring portion acts on the sheet feeding portion so that the sheet feeding roller is pressed against the sheet with a pressing force when a sheet stacking amount is large and so that the pressing force is decreased by canceling moment created by a weight of the sheet feeding portion when the sheet stacking amount is small.

Abstract: Automatic sheet feeding apparatus/recording apparatus include a feed roller 11 for feeding sheets out of a stack holding unit, a separation roller 12, in contact with the feed roller 11, for separating the sheets one by one; a return lever 13 for pushing back sheets to the stack holding unit and aligning them; and flanges 14 integrally turning with the feed roller; wherein the feed roller 11 and the return lever 13 do not overlap with each other but the flanges 14 and the return lever 13 do overlap in a side view during one turn of the feed roller 11. With the configuration, the apparatus can utilize the sheet conveying face of the feed roller longer and more effectively, and to eliminate the rush-in phenomenon, namely letting the tips of sheets enter deep into the feeding apparatus inadvertently at the time of setting the sheets into the sheet stack holding unit.

Abstract: A recording apparatus, in which a recording medium is fed from one side of the recording apparatus, and the recording medium that has been recorded is ejected from the one side of the recording apparatus, is capable of making its size when not in use smaller than the size when in use and also achieving a reduction in the depth dimension of the recording apparatus as compared with the case where a feed tray and a discharge tray are rotary storage trays. The recording apparatus includes a feed tray on which a recording medium is stacked and which is rotated to move between an in-use position and a stowed position, and an eject tray on which the recording medium that has been recorded is stacked and which moves between an in-use position and a stowed position in a discharge direction of the recording medium.

Abstract: A conveying device which can determine whether an error occurred therein. When a transmission unit is in a transmission state, a sheet feed roller is driven by a DC motor to perform first driving for conveying a sheet up to a conveying roller. The occurrence of an error with respect to the sheet feed roller is determined based on information obtained from an encoder during the first driving. When the occurrence of an error is determined, second driving is performed. A conveyance error is determined based on a count value during the first driving and a count value during the second driving, which are both obtained from the encoder.

Abstract: A recording apparatus includes recording heads mounted in a carriage which can move in a direction vertical to a main surface of a recording medium, a guide rail which guides movement of the carriage, and a recovery unit which recovers recording characteristics. The carriage has a regulating section which regulates vertical upward movement of the carriage.
