  • Patent number: 9493018
    Abstract: A printing apparatus configured to perform printing on a sheet that is wound in a roll shape, the printing apparatus including: a feeding unit configured to feed a sheet that is drawn out of a roll sheet of a loaded sheet; a cut unit configured to cut the sheet fed by the feeding unit; and an operation unit configured to operate the feeding unit and the cut unit to function. The operation unit can operate the feeding unit and the cut unit to convey the sheet by an arbitrary amount and cut before the sheet is first printed.

  • Patent number: 8374521
    Abstract: This invention provides an image forming apparatus that includes a storage area to store a print job. Whether the type of printing medium set in the received print job is the same as the type of printing medium provided in the image forming apparatus is determined. Print processing is suspended after storing the print job in the storage area when it is determined that the former type is not the same as the latter type, and the suspension time for which the print job has been suspended is measured. The suspension time is compared with a predetermined period, and the print job is deleted from the storage area when the suspension time reaches the predetermined period.

  • Patent number: 7539454
    Abstract: In a conventional printing apparatus with a plurality of paper feed ports, since a paper type limits the paper feed port usable for paper feed, a user must know in advance a paper feed port to set a paper sheet. This arrangement is not user-friendly. A printing apparatus according to the present invention, however, holds table information indicating the correspondence between paper types and paper feed ports usable for paper feed. When a paper type is designated together with input print data, information on a paper feed port usable for paper feed is acquired from the table information. A message is displayed to prompt the user to set a paper sheet on the paper feed port usable for paper feed so that the user can set an appropriate paper sheet.

  • Patent number: 5616979
    Abstract: This invention relates to a vibration driven motor apparatus and, more particularly, provides a motor apparatus which has a mode for setting the rate of change in frequency in correspondence with the motor speed, and a mode for setting the rate of change in correspondence with the difference between a resonance state and a current vibration state when the frequency of a driving frequency signal in the motor is changed, and selects one of these modes in correspondence with the motor speed.

  • Patent number: 5612598
    Abstract: A drive frequency control system is used for a vibration driven motor including a vibrating member which generates a vibration therein upon application of a frequency signal to an electro-mechanical energy conversion element therein, and which uses the vibration as a driving force. The system includes a power supply circuit for supplying an electric power to the vibration driven motor, and a detection circuit for detecting a power supply voltage level of the electric power supplied by the power supply circuit, the detection circuit determining whether the power supply voltage level is less than a predetermined voltage level. A control circuit performs frequency control of the frequency signal of the basis of the determination of the detection circuit.

  • Patent number: 5493163
    Abstract: A driving device drives a movable member, such as a lens barrel, using a vibration motor through a gear train. The scanning speed of the driving frequency of a periodic signal applied to the motor when the motor is activated is varied according to a backlash of the gear train. In this manner, a movable member can be driven to effect a fine focus adjustment regardless of the existence or non-existence of a backlash in the gear train.

  • Patent number: 4670791
    Abstract: This invention is directed to a method and system which employs a distinguishing document placed between each document set which distinguished the documents for one destination from the documents of another destination. In accordance with this invention, the number of documents within each set are counted by counting the documents fed until the distinguishing document is detected, this number is then compared with the number entered in advance for each destination. When a difference between these numbers occurs, it is then determined that double feeding has occurred and a warning is indicated.
