The information converted into the electric signal is stored in the main body by the control circuit in synchronizing with the movement of the carrier 30. The movement of the carrier 30 is detected by using reflection light sensors 22a, 22b to detect the optical mark 32 recorded on the back side of the carrier 30. The sensor 22b outputs a synchronizing signal in response to stripes of the mark 32.

摘要： PURPOSE: To prevent image defocusing and irregularity in the quantity of light, and to obtain a sharp copy image of good quantity by providing a control member which prevents the image defocusing and setting the distance element lens systems to such a value that the irregularity in the quantity of light in a slit lengthwise direction is prevented.
CONSTITUTION: An image forming device has a projection area controlled in the slit scanning direction by the control member 8. Consequently, even if a relative shift is generated between a lens array and image formation surface and/or an original image surface during image scanning although the projection area of the lens array 7 is generally wide in the slit scanning direction, a shift which causes image defocusing actually is limited to that generated in a short time when a light image crosses the controlled area. On the other hand, the influence to light quantity distribution pattern of each element lens system appears because the projection area is controlled, and irregularity in the quantity of light is generated in the slit lengthwise direction, but the distance between the element lens system in the slit lengthwise direction is adjusted to prevent the irregularity in the quantity of light.

摘要： PURPOSE: To elevate tone reproducibility of image by equipping an optical filter to intercept the light of lower wavelength side than that of oscillation laser light in laser oscillation threshold electric current in an optical path of laser light.
CONSTITUTION: An interference filter 4 composed of the laminated layers of plural pieces of dielectric films is equipped in the optical path of laser light B
0 . The filter is a sharp cut type one whose transmittivity τ is suddenly changed on the near border of a certain wavelength λ
0 to intercept the light on the band side of low wavelength. The wavelength λ
0 is designed to be almost equal to wavelength of oscillation laser light in the oscillation threshold current Ith of laser light. Therefore, the output character of laser light passed through the filter 4 becomes linear over almost all the parts of output range of a semiconductor laser 1. Thus, as compared with the conventional one, modulation of strength of oscillation laser light can be performed, and image of higher tone reproducibility can be obtained in wider range.
