Description

Method and system for a scan module incorporating a printhead

technical field

The invention relates to a multifunctional business machine, in particular to a method and system for a scanning module combined with a printing head.

Background technique

Existing multi-function printers (MFPs) combine image scanners and printing modules, but operate separately functionally. The scanning module and the printing module respectively have a set of drive motors and transmission components, which not only wastes material costs, but also increases the volume, which is not conducive to miniaturization.

FIG. 1 is a schematic cross-sectional structure diagram of a multi-function peripheral 100 . The document 102 is placed face down on a scanning platform 104 . Document 102 is scanned to retrieve its image data and convert it into an electronic signal that can be read by a data processing device or other similar device. The scanning head 106 moves horizontally under the scanning platform 104 for scanning. The scan head 106 includes a linear light source 108 , a lens set 110 , a lens 114 and a light sensor 116 . A first motor 112A is mechanically coupled to the scanning head 106 through gears, cables or other similar components to drive the scanning head 106 to move along the length direction of the scanning platform 104 . The reflected light from the scanning platform 104 is guided by the lens set 110 and the lens 114 is focused on the light sensor 116 . A print head 124 is combined with the scan head 106 and located above the scan head 106 . A second motor 112B is mechanically coupled to the print head 124 through gears, cables or other similar components to drive the print head 124 to move along the length direction of the scanning platform 104 .

The light sensor 116 is preferably a charge-coupled device having a plurality of detector cells in a linear array. Each sensor cell defines a file pixel or a pixel. The image signal output from the light sensor 116 is transmitted to a first control circuit 122A via the cable 120 to convert the image data retrieved by the sensor 116 into a digital signal. The first control circuit 122A also provides a driving signal to the first motor 112A. The second control circuit 122B also provides a driving signal to the second motor 112B. The first control circuit 122A communicates with a central processing unit via a first output cable 126A for data transmission and processing. The second control circuit 122B communicates with a central processing unit via a second output cable 126B for data transmission and processing.

This existing multi-function peripheral adopts a horizontal placement method, and its scanning platform 104 is parallel to the placement surface. The scanning head 106 must be driven by the first motor 112A to move along the length direction of the scanning platform 104 for image retrieval of the scanned object, and the first control circuit 122A must also provide a driving signal to the first motor 112A. The printing head 124 must be driven by the second motor 112B to move along the length direction of the scanning platform 104 to print the scanned object, and the second control circuit 122B must also provide a driving signal to the second motor 112B. Therefore, an existing multifunctional business machine 100 not only occupies a relatively large placement space, but also requires two motor drives to drive the scanning head 106 and the print head 124, and needs to provide power sources to the motor drives.

Based on the above reasons, it is extremely desirable to seek a method and system for combining a printing head with a scanning module.
