摘要： PROBLEM TO BE SOLVED: To set the tip angular parts of all paper positively below a separating claw by guiding the tip of paper set on a hopper, below the separating claw by a guide member at the time of non-feeding action, and retreating the guide member at the time of feeding action of a device. SOLUTION: A guide member 41 is provided to guide the tip Pa of paper P set on a hopper 10, below a separating claw at the time of nonfeeding action so as to set the tip angular part of the paper set on the hopper 10, positively below the separating claw 30. Overlap feed generated by inserting the tip angular part of the paper above the separating claw 30 is thereby prevented. At the time of feeding action, the guide member 41 is retreated by retreat mechanism 50 so as not to impede the formation of bending of the paper, so that separating action by the separating claw 30 is positively performed. Since a free roller 43 is provided at the tip part of the guide member 41, the paper can be smoothly set on the hopper to.

摘要： PROBLEM TO BE SOLVED: To reduce influence of a spring phenomenon of a rear end section of a paper that may cause deterioration in quality of an image by a method wherein the paper is conveyed by a quantity obtained by subtracting, from a normal quantity, a quantity of the paper sprung out when the rear end section of the paper passes through a pressed narrow section between a paper feeding roller and a pressing roller. SOLUTION: A control means 50 controls a driving means D to control a feeding quantity of a paper and controls a head driving means HD to selectively eject ink drops from a head 31. The control means 50 controls the driving means D so as to convey the paper by a quantity obtained by subtracting, from a normal quantity, a quantity of the paper which may be sprung out when a rear end section Pe of the paper P passes through pressed narrow sections 21a, 22a between a paper feed roller 10 and pressing rollers 21, 22 and controls the driving means D so as to convey the paper by a quantity obtained by adding, to a normal quantity, a quantity of the paper which may be sprung out after the rear end section Pe passes through the pressed narrow sections 21 a, 22a.

摘要： PROBLEM TO BE SOLVED: To prevent paper from being diagonally fed with a sliding load decreased when the paper is put in order and increased when the paper is fed to a main unit, by providing an edge guide which guides a side edge of the paper and has the sliding load different in accordance with a slide direction. SOLUTION: Paper is set, a leftward edge guide 150a is slid in a direction X1, outside plates 151a, 151b of both edge guides 150a, 150b are brought into contact with a side edge of the paper. Here, a support part 155a protrusively provided in a front surface of a front plate 154a is vertically displaced in a slide direction, so as to broaden a clearance of the upper/lower support parts 155a when the edge guide is slid in the direction X1, and a sliding load is decreased. When paper is fed to a main unit, when the paper is diagonally fed, a side pressure to the outside plate 151 of the edge guide 150a by a paper end is generated. In this way, the edge guide 150a tends to move in a direction X2, but the clearance of the support part 155a is narrowed, so as to increase the sliding load, so that the paper can be surely regulated by the outside plate 151a of the edge guide 150a.

摘要： PROBLEM TO BE SOLVED: To provide an automatic sheet feeder capable of reducing noises caused when start end positions of a plurality of sheets of recording paper dislocated into a sheet feed passage from a sheet feed tray are pushed back by a sheet return member to a recording paper bundle start end position regulating surface. SOLUTION: A first cam 2, a first cam follower 3, a second cam 4, a second cam follower 5 and a gear 6 are structurally jointed with a working part 12 of the sheet return member 1 and disposed as a mechanism for rotating the sheet return member 1. The first cam 2, the second cam 4, and the gear 6 are integrated and formed, so that the rotation of a sheet feed roller 57 is transmitted to the first cam 2 and the second cam 4 through the gear 6. The first cam follower 3 is oscillated by the rotation of the first cam 2, and the second cam follower 5 is oscillated by the rotation of the second cam 4. The oscillations of the first cam follower 3 and the second cam follower 5 are transmitted to the working part 12 of the sheet return member 1, and the sheet return member 1 is rotated.

摘要： PROBLEM TO BE SOLVED: To provide a paper feed controller which enables recording to be executed by an optimum throughput at all times by executing feeding recording papers by an optimum paper feed interval in accordance with a recording execution form, and to provide a recorder with the paper feed controller. SOLUTION: A paper feed operation for the recording paper P is carried out (step S1). A recording operation is carried out (step S2). A value obtained by adding a transfer amount a to a transfer amount integrated value N is compared with a recording paper length (step S3). When the value obtained by adding the transfer amount α to the transfer amount integrated value N exceeds the recording paper length (Yes in the step S3), the presence/absence of a next page is confirmed (step S7). When the next page is present (Yes in the step S7), the paper feed operation in the step S1 is returned and a next recording paper P is fed. The paper feed interval at this time is set in accordance with the recording execution form by a paper feed interval-setting means, and the next recording paper P is fed by a timing by which the set paper feed interval is provided.
