摘要： The automatic image-property identification is applied for a two-dimensional object on the document table of a scanner. Various informative frames are used for circumscribing the borders of the document sheets. Each frame type is associated with the image properties of a sheet size. The frame types and their associated image properties are stored in a template. When scanning, the program first detects the features of the frame type currently in use. After a frame type is found, the photoelectric converting device can directly read the image properties of the sheet from the template without a prescan.

摘要： The present invention provides a photo printer with an adjustable thermal print head. The printer includes a cantilever mechanism that raises or lowers a thermal print head for either removing a photo or printing the photo. The force exerted on the thermal print head is adjusted by an adjusting mechanism which uses an elastic mechanism with an adjusting screw and a spring. A platen roller feeds the photo through the device. The contacting stress between the thermal print heads and the platen roller is individually adjusted so that pressure can be maintained evenly at all times.

摘要： The present invention relates to a paper feeding module of a color picture printer for driving a picture back and forth through a printing module of the printer for printing. The printer comprises a housing. The printing module is installed inside the housing for printing the paper. The paper feeding module comprises a first roller, a second roller and an elastic device. The first roller is horizontally installed inside the housing and is rotatable. The second roller comprises at least two cylindrical sleeves mounted onto a revolving axle for clamping the paper with the first roller. The second roller is installed in parallel with, in contact with and above the first roller inside the housing, is moveable in a vertical direction, and is rotatable. When the first and second rollers are rotated in opposite directions, the paper is clamped and driven between the first roller and the sleeves of the second roller. The elastic device is installed between the second roller and the housing and comprises a plurality of elastic arms in contact with two ends of the revolving axle of the second roller and the portions of the revolving axle between each adjacent pair of sleeves. The pads uniformly depress the revolving axle of the second roller so that each sleeve of the second roller is maintained in close and even contact with the first roller so as to clamp the paper.
摘要翻译：本发明涉及一种用于通过打印机的打印模块来回驱动图像的彩色图像打印机的送纸模块。打印机包括壳体。打印模块安装在外壳内用于打印纸张。送纸模块包括第一辊，第二辊和弹性装置。第一辊水平地安装在壳体内并可旋转。第二辊包括安装在旋转轴上的至少两个圆柱形套筒，用于将纸与第一辊夹紧。第二辊与壳体内的第一辊平行地与第一辊接触并平行地安装，可在垂直方向上移动并且可旋转。当第一和第二辊沿相反方向旋转时，纸被夹紧并在第一辊和第二辊的套筒之间被驱动。弹性装置安装在第二辊和壳体之间，并且包括与第二辊的旋转轴的两端接触的多个弹性臂和每个相邻的一对套之间的旋转轴的部分。垫片均匀地压住第二辊的旋转轴，使得第二辊的每个套筒保持紧密并且与第一辊均匀地接触以夹紧纸张。
