摘要： A clutch disk assembly (1) is provided between an input shaft and an output shaft to selectively transmit rotation therebetween. The clutch disk assembly (1) is provided with a dampening mechanism (4) to provide smooth transition during engagement and disengagement of the clutch disk assembly. The dampening mechanism (4) has a more durable second retaining plate (32) with a rectangular window portion for transmitting torque. This second retaining plate (32) has a second receptacle (36) to support a first spring (16). The second retaining plate (32) includes a disk-like plate main body. The second receptacle (36) is formed from that plate main body. The second receptacle (36) projects in an axial direction from the plate main body. The second receptacle (36) includes an axially supporting part (36a) and a circular supporting part (36b). The axially supporting part (36a) supports an axially outside part of the first spring (16) and continues in a radial direction. The circular supporting part (36b) supports both end parts of the first spring (16), and is formed on both circular ends of the axially supporting part (36a). A second hole (36f) is formed at both corners of an inner circumferential side of the axially supporting part (36a). The second holes (36f) are elongated holes that extend in a radial direction.

摘要： An image processing apparatus includes an image forming device, a reading device, and circuitry. The image forming device is configured to form a first pattern on a recording medium. The first pattern includes a plurality of patches in a plurality of tones. The reading device is configured to read the first pattern. The circuitry is configured to acquire read data of the first pattern from the reading device. The read data includes red, green, and blue (RGB) color space values. The circuitry is further configured to: correct the read data based on information indicating a relationship between a color and a position in the first pattern to reduce variation in readings due to a read position of the first pattern; convert the read data corrected into device-independent data; and adjust a color reproduction characteristic of the image forming device based on the device-independent data.

摘要： An image reader includes a reading device to read an image on a recording medium, a first conveying roller pair upstream of the reading device in a conveyance direction of the recording medium, a second conveying roller pair downstream of the reading device in the conveyance direction, to hold the recording medium together with the first conveying roller pair to convey the recording medium, and a driver to drive the first conveying roller pair and the second conveying roller pair so that a relative relation between a reading position of the reading device and the recording medium held by the first conveying roller pair and the second conveying roller pair is constant. The reading device determines that the image read from the recording medium is effective in a period in which the relative relation is constant.

摘要： A photoelectric conversion device includes a plurality of light receiving elements, a plurality of A/D conversion units, and an offset giving unit. The light receiving elements are arrayed in one direction and each convert a light signal into an electrical signal. The A/D conversion units perform A/D conversion on the electrical signals output from the light receiving elements. The offset giving unit gives an offset voltage of a certain level to the electrical signals output from the light receiving elements without flowing a steady current before the electrical signals are input into the A/D conversion units.
