  • Patent number: 6367837
    Abstract: A seated-state detection sensor is disposed in a seat portion of a seat cushion of a passenger seat. The seated-state detection sensor is divided into three parts, that is, a first seated-state detection sensor, a second seated-state detection sensor and a third seated-state detection sensor, which are arranged in this order from the rear side of the vehicle. The first seated-state detection sensor and the second seated-state detection sensor are designed to determine whether or not there is a passenger seated. The second seated-state detection sensor and the third seated-state detection sensor are designed to detect forward displacement of the passenger.

  • Patent number: 6356200
    Abstract: A sensor attaching portion of an upper rail and a sensor attaching portion of a cushion frame are provided with a sensor attaching plate having a sensor disposed thereon. The upper rail and the seat cushion frame are connected with a bracket at a position facing the sensor attaching plate. When the passenger sits on the seat, the seat cushion frame moves down and a bent portion of the bracket is pressed and deformed downwards. At this time, the center in the vertical direction of the sensor attaching plate is bent outward in the lateral direction of the seat. The sensor serves to detect the generated deformation.

  • Publication number: 20020024257
    Abstract: According to the invention, the presence of a child seat mounted on a vehicle seat or the presence of a passenger seated in the vehicle seat is determined automatically. A child seat detecting apparatus incorporated into a vehicle seat is provided with a plurality of load sensors comprising stress sensors or the like, and a determining function for monitoring a relative change of each load detected by each load sensor and determining whether a child seat is mounted on the vehicle seat or whether a passenger is seated in the vehicle seat by the difference of the change of each load. Accordingly, this child seat detecting apparatus makes it possible to accurately determine whether a child seat is mounted on the vehicle seat or whether a person of small stature yet who does not require a child seat is seated in the vehicle seat.

  • Patent number: 6240271
    Abstract: Developing devices are provided adjacent to a light sensitive element. An intermediate transfer drum is provided adjacent to the light sensitive elements. After exposure of the light sensitive element, a first color or third color image is formed on the light sensitive element. On the other hand, after exposure of the light sensitive element, a second color or fourth color image can be formed on the light sensitive element. The first color image is transferred from the transfer unit to the intermediate transfer drum at the first transfer portion, and the second color image is transferred from the transfer unit at the second transfer portion so as to be superimposed on the first color image. Similarly, the third color image is transferred so as to be superimposed on the second image and the fourth color image is transferred so as to be superimposed on the third color image to the intermediate transfer drum. Accordingly, the first to fourth color images are superimposed.

  • Patent number: 6188419
    Abstract: In conventional color digital copy machines, when copying in color mode, the polygon mirror of the laser beam scanner for black, which is driven at a higher speed than those of the other colors, is switched to a slower speed in conformity with the speed of the polygon mirrors for the other colors. However, a drawback of this structure is that, especially when switching from monochrome to color mode, the time required to obtain the first copy is lengthened, and the operating efficiency of copying is poor. In the present invention, when copying in color mode, the rotation speed of the polygon mirror of the laser scanner unit for black is not changed at all, but, by skipping certain mirror surfaces of the polygon mirror, and/or by skipping certain of a plurality of laser light sources, the scanning density of the laser scanner unit for black can be brought into conformity with that of the laser scanner units for the other colors.

  • Patent number: 6094208
    Abstract: In this digital color copier, laser beam scanner units of the same configuration are arranged in parallel with each other, and all are controlled in a unified manner by a laser control unit provided outside the units. In order to synchronously rotate the polygon mirrors in a precise manner, the speeds of rotations of their motors, fed back from tacho-generators are compared to the reference frequency generated from an oscillator so as to allow a motor control circuit to control the driving motors of the polygon mirrors. Further, the BD signals from beam detectors (BD) are fed back to the laser control unit so that all the BD signals from the laser scanner units for black and the three colors can become synchronized with each other, thus enabling control of the polygon mirrors.

  • Patent number: 5982524
    Abstract: The present invention is intended to reduce a f.theta. correction error by correcting an error of an object scanning speed which is produced because a reflecting point of a laser beam moves on a polygon mirror. In an inventive laser scanner, laser light emitted from a laser oscillator is condensed into a beam by a condenser lens at first. This laser beam is reflected by a polygon mirror rotated by a scanning section and is reflected again to a photoreceptor by a curved reflecting mirror. A curved profile of a reflecting plane of the curved reflecting mirror in the main scanning direction is formed so as to be asymmetrical on right and left bounding about a scanning center point. Thereby, variation of speed for scanning the curved reflecting mirror by the light reflected by the polygon mirror may be canceled by the curved reflecting mirror and a speed for scanning the object may be fixed almost at a predetermined speed.

  • Patent number: 5563397
    Abstract: A card C having a predetermined thickness is guided by guide grooves formed in corresponding projecting portions of a card slot to enter. When the leading end of the card C is brought into contact with the lower edges of contact portions of a shutter member, the shutter member is pivoted about the front end sides of arm portions. A shutter plate arranged on the rear end side of the shutter member is moved upward to allow the card C having the predetermined thickness to pass deep. If a card C' having a thickness smaller than the predetermined thickness enters, a regulation portion projecting from the lower portion of the shutter plate of the shutter member is located lower than the bottom surface of a card passage. The leading end of the card C' having the smaller thickness is brought into contact with the regulation portion to prevent the card C' from entering deep.
