摘要： An image forming apparatus includes a first sheet supply cassette which is used for automatic feeding and a second sheet supply cassette which is used for either automatic or manual sheet feeding. Both of these cassettes are detachably mounted and house sheets to be used in paper coyping. The second sheet supply cassette has a sheet supply guide which can be switched between a first position for manual feed and a second position for automatic feed. A structure is also provided for selecting which of the first and second cassettes are to be used for feeding, and a control structure generates control signals in response to the condition of the sheet supply cassettes. After the sheets are supplied, an image is formed on the sheets which have been fed.

摘要： A rotational velocity control apparatus of a document-scanning motor in a copying machine comprises a first velocity detector for detecting the rotational velocity of a photosensitive drum and for generating a signal of a frequency corresponding to the detected velocity, a frequency converter circuit for multiplying the frequency of the output signal from the first velocity detector and for frequency dividing the signal in accordance with a selected magnification, a second velocity detector for detecting the rotational velocity of a scanning motor and for generating a signal having a frequency corresponding to the detected velocity, and a motor controller for controlling the rotational velocity of the scanning motor such that the frequency of the output signal from the second velocity detector is proportional to that of the output signal from the frequency converter circuit. The frequency converter circuit has a phase locked loop control circuit having a frequency divider in its feedback loop, the frequency division ratio of which is changed in accordance with magnification. The motor controller also has in its feedback loop a frequency divider having a frequency division ratio which is changed in accordance with magnification. The proportional constant of the frequency of the output signal from the second velocity detector to that of the output signal from the frequency converter circuit is changed in accordance with the selected magnification.

摘要： A feed member is selectively driven and brought into contact with an image forming medium so as to feed the image forming medium stored in a storage section in a direction toward an image forming section. A drive mechanism selectively applies a force to the feed member so that the feed member is brought into contact with the medium so as to feed the medium. A controlling means supplies a first control signal to the drive mechanism in response to a medium feed instruction signal. The medium can be sufficiently fed in accordance with the first control signal. The controlling means also supplies a second control signal to the drive mechanism in response to an error processing instruction signal when an error occurs. The feed member is separated from the medium in accordance with the second control signal.
