Technical Field

[0001] This utility model relates to a paper feed port structure for a scanning device, and also to a device that combines scanning and printing, belonging to the field of printing, scanning and printing technology. Background Technology

[0002] Printers and scanners are indispensable office supplies. To reduce space requirements, multi-function printers have emerged on the market, combining printing and scanning functions into one machine. The casing of a multi-function printer has a scan paper feed port, a scan paper output port connected to the scan paper feed port, a print paper feed port, and a print paper output port connected to the print paper feed port. The scan paper feed port often has a platen to support the document to be scanned, but the platen protrudes laterally from the casing, making packaging and handling inconvenient. Furthermore, the width of the scan paper feed port is not adjustable, causing the scan to be tilted or incomplete after paper is fed in. Therefore, improvements are needed. Utility Model Content

[0004] The second technical problem to be solved by this utility model is to provide a scanning and printing all-in-one machine with a table assembly that can be stored and an adjustable scanning paper feed channel width, in view of the above-mentioned technical status.

[0005] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a scanning paper feed channel width adjustment structure, including a housing, the aforementioned housing having a scanning paper feed port and a scanning paper output port communicating with the scanning paper feed port, characterized in that the outer end of the housing near the scanning paper feed port is provided with a platform assembly for supporting the document to be scanned, the platform assembly including a base plate and two baffles disposed on the base plate and movable along the length direction of the base plate, the aforementioned base plate being flip-mounted on the aforementioned housing and capable of covering the scanning paper feed port, the spacing between the aforementioned baffles matching the width of the document to be scanned.

[0006] Furthermore, the upper surface of the substrate has a strip groove, and the baffle includes a baffle portion and a claw portion located at the lower end of the baffle portion. The aforementioned claw portion has an elastic force perpendicular to the length direction of the substrate and engages with the aforementioned strip groove in a damping manner.

[0007] Furthermore, the claw portion has a notch in the middle and protrusions on both sides of the front end.

[0008] Preferably, the strip groove has a first guide rib along its length, and correspondingly, the lower end face of the stop has a first guide groove that guides and cooperates with the aforementioned first guide rib.

[0009] Furthermore, the upper surface of the substrate is provided with a cover plate that can cover the strip groove, and the cover plate has a strip hole along the length direction for the blocking part to extend and slide.

[0010] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a scanning and printing all-in-one machine, characterized in that the machine casing has a printing paper inlet port and a printing paper outlet port communicating with the printing paper inlet port.

[0011] Furthermore, the printing paper feed port is equipped with two limiting plates that can adjust the width of the printing paper feed, and the distance between the two limiting plates matches the width of the printing paper.

[0012] Preferably, the printing paper feed port is equipped with a flip-up printing assembly, which includes a printing bracket, a thermal printhead mounted on the printing bracket, and an end cap mounted on the printing bracket. The printing bracket has a strip-shaped guide groove, one side of which is formed with serrations. Correspondingly, one side of the limiting plate has an elastic buckle that engages with the aforementioned serrations for damping. The limiting plate is movably disposed within the aforementioned guide groove. The serrations and the elastic buckle engage to generate damping, thereby positioning the limiting plate in a set position.

[0013] Furthermore, a second guide groove is formed on one side of the limiting plate, and correspondingly, the printing bracket has a second guide rib near the guide groove that guides and cooperates with the aforementioned second guide groove.

[0014] Compared with existing technologies, the advantages of this invention are as follows: when the scanning paper feed path needs to be adjusted, simply move the two baffles; the distance between the baffles determines the width of the scanning paper feed, accommodating scanning documents of various widths. Furthermore, when the scanning function is not in use, the platform assembly can be flipped over for easy storage and portability. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 and Figure 2 As shown, the scanner-printer in this embodiment includes a housing 1 and a printing assembly 2 that is rotatably mounted on the housing 1. The housing 1 has a scanning paper feed port 1c, a scanning paper output port 1d communicating with the scanning paper feed port 1c, a printing paper feed port 1a, and a printing paper output port 1b communicating with the printing paper feed port 1a. In this embodiment, the housing 1 is assembled from a base 11 and a top cover 12.

[0030] Combination Figures 3-5 As shown, the outer end of the housing 1 near the scanning paper feed port 1c is provided with a platform assembly 3 for supporting the document to be scanned. The platform assembly 3 includes a base plate 31, two baffles 33 disposed on the base plate 31 and movable along the length direction of the base plate 31, and a cover plate 32. Figure 12 As shown, the substrate 31 is flip-mounted on the housing 1 and can cover the scanning paper feed port 1c, and the spacing between the baffles 33 matches the width of the document to be scanned.

[0031] The upper surface of the substrate 31 has a strip groove 312. The baffle 33 includes a stop portion 331 and a claw portion 332 located at the lower end of the stop portion 331. The claw portion 332 has an elastic force perpendicular to the length direction of the substrate 31 and engages with the strip groove 312 in a damped manner. The claw portion 332 has a notch 333 in the middle and protrusions 334 formed on both sides of the front end. The strip groove 312 has a first guide rib 313 along the length direction. Correspondingly, the lower surface of the stop portion 331 has a first guide groove 335 that engages with the first guide rib 313.

[0032] The upper surface of the substrate 31 is provided with a cover plate 32 that can cover the strip groove 312. The cover plate 32 has a strip hole 321 along its length for the blocking part 331 to extend and slide. Figure 6 As shown, the cover plate 32 can be marked with scales to facilitate quick adjustment of the baffle.

[0033] Moving the platen is achieved by tossing the stop; releasing it allows it to stay in position due to the damping effect between the claw and the inner wall of the slot. When the scanning function is not in use, the platen assembly can be flipped over for storage (e.g., ...). Figure 12 (As shown), it is easy to carry.

[0034] Combination Figures 7-11 and Figure 13 As shown, the printing paper feed port 1a is provided with a flip-up printing component 2. The printing component 2 includes a printing bracket 21, a thermal print head 24 disposed on the printing bracket 21, and an end cap 22 covering the printing bracket 21. Two limiting plates 23 that can adjust the width of the printing paper are disposed on the printing bracket 21, and the distance between the two limiting plates 23 matches the width of the printing paper.

[0035] like Figure 13 As shown, when the paper in the printing feed path malfunctions or the print head or rollers need cleaning, the printing assembly needs to be flipped.

[0036] The printing bracket 21 has a strip-shaped guide groove 211, and a serration 212 is formed on one side of the guide groove 211. Correspondingly, one side of the limiting plate 23 has an elastic buckle 232 that dampens with the serration 212. The limiting plate 23 is movably disposed within the guide groove 211. A second guide groove 233 is formed on one side of the limiting plate 23. Correspondingly, the printing bracket 21 has a second guide rib 213 near the guide groove 211 that guides and engages with the second guide groove 233.

[0037] Movement can be achieved by moving the limit plate, and it will be positioned when released due to the damping effect of the elastic buckle and the serrations.
