A print device includes a housing, a lid body, a display device, and a mounting portion. An opening is formed in an upper portion of the housing. The lid body opens and closes the opening of the housing by a second end portion side of the lid body pivoting around a predetermined rotation axis provided at a first end portion of the lid body. The mounting portion is provided on an upper portion of the lid body when the opening is closed. The display device can be attached to and detached from the mounting portion along a predetermined attachment/detachment direction with respect to the lid body. The attachment/detachment direction is orthogonal to an extending direction of a tangent line. The tangent line is tangential to a circumferential direction of the rotation axis at a position of the second end portion of the lid body.

A memory device includes a compressed color table and corrective information. The compressed color table includes a first set of nodes of the color table compressed with a lossy compression at a selected compression ratio. The first set of nodes include a color difference within an error threshold at the selected compression ratio. Corrective information is included for a second set of nodes of the color table. The second set of nodes have a color difference outside the error threshold.

An image reading device includes a turning unit and a reading unit having a reader. The reading unit includes a reading glass, and the reader reads, through the reading glass, an image on a sheet placed on the reading glass. The turning unit turns with respect to the reading unit and includes a pressing plate, a communication unit detachably mounted within the turning unit, and an attachment part. The pressing plate presses a sheet on the reading glass against the reading glass when the turning unit is at a position closing the reading glass. The communication unit receives data from outside the image reading device. The attachment part can be attached the communication unit. At least part of the pressing plate is removed from a main unit of the turning unit to externally expose the attachment part.

An expanding appliance includes a connect port, an image capturing module, an intelligent control module, an image transmitting module, and a result displaying module. The expanding appliance connects an image input device through the connect port, connects a display device through the result displaying module, and connects one or more image-applied function module through the image transmitting module. The intelligent control module generates a demanding command according to a successfully-connected image-applied function module. The image capturing module controls the image input device to capture image data based on the demanding command, and quantizes samples of the image data as computation data. The image transmitting module provides the computation data to the image-applied function module for image identification and receives an identification result. Finally, the intelligent control module triggers the result display module for displaying the identification result on the display device.

In some examples, a component for a printing device includes a memory device comprising a plurality of corrective data to produce a corresponding plurality of color tables each customized for a respective media type of a plurality of media types, wherein a respective corrective data of the plurality of corrective data corresponds to nodes of a reference color table for the printing device that is able to accept the plurality of media types for printing. The respective corrective data includes a plurality of residual values to transform the nodes of the reference color table to a customized color table for use with a selected media type of the plurality of media types.
