ている。 As this cut sheet feeding device, a paper feeding roller is installed in a paper storage space formed by a pair of covers consisting of an opening/closing cover (usually an upper cover or a front cover) and a fixed cover (usually a lower cover or a rear cover). An intermediate plate for holding the cut sheet is provided between the roller and the fixed cover and is biased by a spring toward the paper feed roller, and a separating claw is provided in front of the intermediate plate and comes into contact with the front end of the cut sheet. A type of apparatus has been proposed in which a paper feeding roller is rotated and the cut sheets pressed against the roller are separated one by one by the separating claw and sent out.

As is clear from the above description, according to the present invention, in a cut sheet supply device provided in a recording apparatus main body for supplying cut sheets to a recording section of the recording apparatus main body, the cut sheet supply device includes: cut sheet support means arranged to stack and support cut sheets; feeding means disposed within the case to feed out the cut sheets by contacting the cut sheets supported by the cut sheet support means; the cut sheet support means and the feeding means; a separating means for separating the cut sheet from the cut sheet supporting means and the feeding means in the case, the separating means being provided in the case so as to cover the cut sheet supporting means and the feeding means, and opening and closing the case in order to open the upstream rear end and load the cut sheet into the cut sheet supporting means. an opening/closing cover that can be attached to the opening/closing cover; and a guide member that is provided on the upstream side of the feeding means in the opening/closing cover and guides the front end side of the cut sheet to be inserted when loading the cut sheet into the cut sheet supporting means. The guide member is in a position where it does not come into contact with the cut sheet supported by the cut sheet supporting means when the opening/closing cover is closed, and when the opening/closing cover is opened, the inserted cut sheets are separated by the separating means. Since the cut sheet is positioned so as to be guided between the cut sheet supporting means and the feeding means, there is no possibility that the leading end of the cut sheet may be bent when it hits the feeding means with a large coefficient of friction, or the cut sheet may be warped. By eliminating the inconvenience of not inserting the cut sheet into the specified position when the cut sheet is deformed, it is possible to load the cut sheet easily and accurately. Provided is a cut sheet feeding device that can feed sheets smoothly because of its distance from the cutting sheet.
