Embodiment Construction

[0035] The imaging device of the present invention can be an inkjet printer, a laser printer, a copier, a facsimile machine, an all-in-one machine, etc. The present invention will be described in detail below in conjunction with various embodiments.

[0036] Inkjet printer example:

[0037] The imaging device of this embodiment is an inkjet printer, which has a casing, and a printing carriage is arranged inside the casing, and the printing carriage can reciprocate along the slide bar. The printing carriage has a cavity, and a plurality of ink cartridges as consumable containers are installed in the cavity. Each ink cartridge has a shell, and a cavity for containing ink is formed inside the shell. An ink outlet is provided under the cavity of the ink cartridge, and the ink passes through the outlet Ink comes out.

[0038] A chip is installed on the outer wall of the ink cartridge housing, which has a substrate, and one side of the substrate is provided with a plurality of elec...

Abstract

The invention provides a data storage device, a data access method and an imaging device. The data storage device comprises a controller, a first group of storage units and a second group of storage units, wherein the controller is connected with a first bus and a second bus, clock pins of storage units in the first group of storage units are all connected with the first bus, data pins of the storage units in the first group of storage units are all connected with the second bus, clock pins of storage units in the second group of storage units are all connected with the second bus, and data pins of the storage units in the second group of storage units are all connected with the first bus. The data access method comprises the steps of sending clock signals to the first bus and sending data signals to the second bus when the controller accesses the first group of storage units; and sending the data signals to the first bus and sending the clock signals to the second bus when the controller accesses the second group of storage units. According to the data storage device, the data access method and the imaging device, the number of storage units connected with the controller can be increased, and working requirements of the imaging device can be met.

Description

technical field [0001] The invention relates to the field of data storage and access, in particular to a data storage device and its data access method, and an imaging device provided with the data storage device. Background technique [0002] Imaging equipment, such as printers, as common office equipment, provides great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need to be printed on the medium. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provided with...
