Abstract
A method for discarding sheets of used photosensitive material from an image or the like wherein the amount of discarded sheets which can be held in a storage box is increased. Used photosensitive sheets are conveyed to a discarding section where they are cut off in lengths sufficiency short that the sheets cannot fold on themselves when placed in the storage box but sufficiently long that they can be conveyed in the apparatus.
Claims1
A method of discarding a sheet from an image recorder into a storage box having a bottom of a specified width, comprising the steps of:
- detecting the conveyance of said sheet with a sensor at a position upstream of a cutter positioned between first and second pairs of conveyance rollers;
- starting a time count when conveyance of said sheet is detected;
- and
- cutting said sheet to a cut-off length when the time count reaches a value indicating that said cut-off length of said sheet is greater than a distance between said first and second rollers and less than said width of the bottom of the box, wherein prior to said step of cutting said sheet to said cut-off length, said sensor and said cutter are separated by a distance not smaller than said distance between said first and second rollers whereupon if said sensor no longer senses said sheet, said time count is terminated so that said sheet is not cut to insure that said sheet maintains a length not less than said distance between said first and second rollers thereby permitting conveyance thereof from said recorder.
