  • Patent number: 10699106
    Abstract: A direction discrimination device includes: an extraction unit configured to extract pieces of feature information from an image of a person, each of the pieces of feature information representing a feature of corresponding one of portions of the person; and a discrimination unit configured to discriminate a direction of the person based on the pieces of feature information. The discrimination unit is configured to weight first feature information which is feature information of a portion that is likely to have a difference in the feature between a first direction and a second direction range, more than second feature information which is feature information of a portion that is less likely to have a difference, in determination of the direction of the person. The second direction range not includes the first direction and includes a second direction opposite to the first direction.

  • Patent number: 5241346
    Abstract: An image forming apparatus of the present invention has an image forming device including an image scanning device and an automatic document feeder. A document on a platen located on the image forming device is positioned in a predetermined position. The scanning device starts the scanning operation from a starting position opposite to the predetermined position. The scanning position of the scanning device is individually determined to be a position corresponding to the document size detected by the detecting device. Therefore, the image forming operation is performed without failing to form the image on the copying paper. Furthermore, the speed of the image forming operation is increased.

  • Patent number: 4739983
    Abstract: A document feeder for use with an image forming device such as a copy machine. An original document is first transported from an original document feed port toward an original exit port until a trailing end of the original passes a predetermined stop position whereat an imaging operation is to be carried out. By transporting until the trailing end passes the stop position, there is time for a previous original to exit from the original exit port. Then the original document is fed back toward the original feed port until the trailing end of the original is properly positioned so that the document can be imaged.

  • Patent number: 4679927
    Abstract: An image forming apparatus for a photocopy machine. A document table holds the document to be copied. An image area designating panel on the document table designates the area of the document to be copied and generates electrical signals corresponding to the copy area when the panel is pressed. A memory stores the electrical signals generated by the panel and a plurality of light-emitting elements prevents the formation of the electrostatic latent image on the photosensitive body except for the indicated copy area, according to the electrical signals which are read from the memory.

  • Patent number: 4657376
    Abstract: An image forming apparatus reciprocally operates one of the image forming body units and the document feeding units. A first control circuit produces signals necessary for image formation operation, while keeping an automatic document feeder in a wait state. A second control circuit operates the automatic document feeder only when the image formation operation is not in progress. Therefore, the power source which is provided can be shared between the image forming body unit and the automatic document feeder without the necessity for excess capacity.

  • Patent number: 4610446
    Abstract: A sheet material transporting apparatus has a first convey portion for conveying a sheet having an image on one surface thereof in a first direction along a first convey path, the image being formed by an image-forming section, and a second convey portion for conveying the sheet in a second direction along a second convey path extending to the image-forming section through the first convey path so as to form an image on the other surface of the sheet. A trailing edge detector is arranged in the vicinity of a branched portion between the first and second convey path to detect the trailing edge of the sheet. In a sheet guide portion for causing the branched portion between the first and second convey paths to communicate with the discharge portion, the sheet is sent in a first direction for a predetermined period of time after the trailing edge of the sheet is detected by the trailing edge detector to invert the sheet conveying direction to the second convey path.
