摘要： A sheet conveying apparatus permits keeping predetermined sheet intervals, even when sheet conveyance is temporarily discontinued and then resumed, after resumption of conveyance. The sheet conveying apparatus has a first roller which feeds sheets at predetermined sheet intervals, and a second roller which conveys a plurality of sheet fed from the first roller. After temporarily discontinuing conveyance of the plurality of sheets, conveyance of the plurality of sheets is resumed by use of the first roller and the second roller. The variation in the sheet interval caused when temporarily discontinuing sheet conveyance is corrected upon resumption of sheet conveyance.

摘要： The present invention aims at restoring backup data in a predetermined order and avoiding damage from being given to the system even when the backup data are destroyed. Flags Ferr and Feeprom and a variable i stored in a DRAM are initialized (S1 to S3). When the variable i is smaller than the number n of EEPROMs (hereinafter referred to as “PROM(s)”), the ID code of a PROM in question is read and loaded into the DRAM (S4 to S6). When the variable i equals the number n, the variable i is cleared (S7). Then, a variable j is initialized (S9), and it is determined whether or not each PROM ID stored in the DRAM matches with a mask ROM ID until the variable j becomes greater than the number n of PROMs (S11). If the answer is “No”, the variable j is incremented (S13), while if “Yes,” a number corresponding to the variable j then assumed is loaded into the DRAM as the flag Feeprom (S14). Data in the PROM in question is transferred to an area of the DRAM in which is stored the PROM ID matching with the mask ROM ID.

摘要： The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.
