[0032] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. The following is a further description in conjunction with the attached Figures 1-4 A further description will be made on the single and double scan bar switchable device.

[0033] Embodiment 1

[0034] A single and double scan bar switchable device, where a scan lower housing 11 is connected to a scan upper housing 12 to form a lower scan component frame; a scan bar component 15 is disposed inside the lower scan component frame; a scan motor 17, a belt 18, and a scan drive gear assembly 19 are all disposed inside the scan lower housing 11; the scan motor 17 is connected to the belt 18 through the scan drive gear assembly 19; the lower scan bar seat 16 is connected to the belt 18. When the motor 17 rotates, through a series of gear transmissions of the drive gear assembly 19 and the synchronous transmission of the belt 18, the required speed is transmitted to the scan bar seat 16 connected to the belt, driving the lower scan component 15 to move.

[0035] An upper scan component is disposed above the lower scan component, and the upper scan component includes: a document feeder upper cover assembly 27 is disposed below a document feeder base 25; a upper scan bar component 22 or a scan guide cardboard 23 is detachably disposed on the document feeder base 25.

[0036] A front glass plate 13 is disposed above the scan bar component 15, a scan bar carriage 14 is connected to the scan bar component 15, a lower scan bar seat 16 is disposed below the scan bar component 15, a document feeder support spring 21 is disposed inside the document feeder base 25, an upper scan bar seat 28 is connected to the document feeder base 25, and a rear glass plate 24, and the rear glass plate 24 is disposed below the document feeder base 25.

[0037] Preferably, it further includes a scan bar seat claw 26, and the scan bar seat claw 26 is disposed above the document feeder base 25. The scan bar seat claw 26 limits the position of the scan bar component to ensure the relative precise position between the scan bar and the paper.

[0038] The lower scan bar component performs a reciprocating motion of the lower scan bar by receiving a scan instruction sent by the CPU, and the scan bar spring is used to smoothly pass papers of different thicknesses.

[0039] When using a single scanning strip, the scanning guide paper board 23 of the document feeder is installed inside the document feeder base 25. The Z-shaped bends on both sides of the scanning guide paper board 23 cooperate with the limiting structure of the document feeder base 25 to control the thickness of the scanning medium channel. Under the scanning guide paper board 23, there is a document feeder support spring 21, which can freely float and descend according to the thickness of the scanning medium. One side of the bottom of the document feeder support spring 21 is connected to the document feeder base 25, and the other side is connected to the scanning guide paper board 23, and the spring force can vary according to the different thicknesses of the scanning medium.

[0040] When using a double scanning strip, remove the scanning guide paper board 23 and replace it with the upper scanning strip assembly 22. When the scanning medium passes through the document feeder upper cover assembly 27 and the document feeder base 25 and runs to the rear glass plate 24, and then passes through the upper scanning assembly and the lower scanning assembly for two-way scanning.

[0041] Embodiment 2

[0042] As a new embodiment or a supplement to Embodiment 1.

[0043] This embodiment consists of the following components: document feeder support spring 21, upper scanning strip assembly 22, scanning guide paper board 23, scanning strip assembly 15, front glass plate 13, rear glass plate 24, document feeder base 25, document feeder upper cover 27.

[0044] The lower scanning assembly, as an independent scanning unit, consists of a scanning lower housing 11, a scanning upper housing 12, a front glass plate 13, a scanning strip carriage 14, a scanning strip assembly 15, a scanning strip spring, a lower scanning strip seat 16, a scanning motor 17, a belt 18, a scanning transmission gear assembly 19, etc. The scanning strip assembly 15, the scanning motor 17, the belt 18, and the scanning transmission gear assembly 19 are installed inside the scanning lower housing 11. Under the lower scanning strip assembly, there is a scanning strip spring, and above the scanning strip assembly 15, there is a front glass plate 13.

[0045] The upper scanning assembly consists of a document feeder support spring 21, an upper scanning strip assembly 22 or a scanning guide paper board 23, a rear glass plate 24, a document feeder base 25, a document feeder transmission assembly, a document feeder upper cover assembly 27, etc. The upper scanning strip assembly 22 includes a scanning strip assembly and an upper scanning strip seat 28. The scanning strip assembly is installed inside the scanning strip seat. On the back of the upper scanning strip seat, there is a document feeder support spring 21, and the document feeder support spring 21 is installed inside the document feeder base 25.

[0046] The platen base 25 provides a stable support platform. On this platform, the scanning guide paperboard 23 is ingeniously installed inside the platen base 25, and its two sides are designed with Z-shaped bends. This special design enables the scanning guide paperboard 23 to closely cooperate with the limiting structure of the platen base 25, thereby precisely controlling the thickness of the scanning medium channel. This control is crucial for the scanning quality because it ensures that the scanning medium can maintain an appropriate thickness when passing through, avoiding the decline in scanning quality caused by different medium thicknesses. At the same time, a platen support spring 21 is installed below the scanning guide paperboard 23, and this design enables the scanning guide paperboard 23 to freely float and descend according to the thickness of the scanning medium. In this way, whether it is thick cardboard or thin paper, an ideal scanning effect can be obtained.

[0047] When higher scanning efficiency or finer scanning effect is required, a single scanning bar may not meet the needs. At this time, a double scanning bar needs to be used for work. In this mode, first, the original scanning guide paperboard 23 needs to be removed, and then the upper scanning bar assembly 22 is used to replace its position. The upper scanning bar assembly 22 works in coordination with the lower scanning assembly to form a two-way scanning system.

[0048] When the scanning medium is placed on the platen, it will be guided by the platen upper cover assembly 27 and then enter the platen base 25. Before reaching the rear glass plate 24, the scanning medium will first pass through the upper scanning bar assembly 22 for the first scan. Subsequently, the scanning medium continues to move forward and passes through the lower scanning assembly for the second scan. This two-way scanning method can greatly improve the scanning efficiency and accuracy, especially suitable for scenarios with high requirements for scanning quality.

[0049] Generally speaking, whether using a single scanning bar or a double scanning bar, the platen can meet the scanning needs of different users through its delicate design and flexible configuration. Whether it is simple daily office scanning or high-precision professional scanning tasks, the platen can easily handle them.

[0050] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and can also make simple deductions and substitutions without departing from the inventive concept of the present utility model, all of which should be covered within the protection scope of the present utility model.
