Technical Field

[0001] The present invention relates to the technical field of printers, and specifically relates to a convenient printer with an anti-paper jam paper feeding passage and a use method thereof. Background Art

[0002] As the name suggests, a portable printer has a simple structure and a small size, making it easy to carry around.

[0003] A wide-format portable printer can be adapted to print papers of various specifications. When a smaller size of printing paper is needed, it needs to be adjusted and adapted through a width adjuster. However, a conventional width adjuster and a paper feed guide are fitted together, and the fitting surface is consistent with the direction in which the paper enters. This makes it easy for the paper to get stuck between the width adjuster and the paper feed guide, causing a paper jam. If the contact surface between the width adjuster and the paper feed guide is changed to face away from the direction in which the paper enters, the paper jam can be avoided. Therefore, a portable printer with an anti-paper jam paper feed channel and a method for using the same are proposed. Summary of the invention

[0006] The adapter component includes symmetrically arranged adapter blocks and an adapter plate arranged at the bottom of the paper feed end. The adapter block is provided with a connecting end connected to the adapter plate. The gap between the adapter block and the adapter plate is eliminated by connecting the connecting end to the adapter plate. Synchronous adjustment components are installed on the two adapter blocks.

[0007] Preferably, the paper feed end has an arc-shaped opening, a movable groove is provided at the bottom lower end of the paper feed end, the bottom of the adapter plate is flexibly connected to the edge of the movable groove, an elastic component is provided between the adapter plate and the bottom of the movable groove, and the adapter plate is supported by the elastic component so that it is at the opening of the movable groove and is flush with the arc surface of the paper feed end.

[0011] Preferably, a method for using a convenient printer comprises the following steps:

[0012] Step 1: First, adjust the distance between the two adapter blocks according to the size of the paper required for printing, so that it can fit the paper, thereby avoiding the situation where the paper is tilted when entering and the paper jams and cannot be printed after tilting;

[0013] Step 2: By sliding the tooth block, the tooth block can simultaneously drive the two tooth blocks to move in the same direction or opposite directions under the action of the gear, thereby driving the adapter blocks to move closer to or away from each other. When the connecting end is out of the slot, the adapter plate is pushed to move into the movable slot, and the elastic component contracts until the connecting end reaches the next slot, completing the adaptation of the paper.

[0014] Step three, then put the paper vertically in from the paper feed end, and limit the paper by the adapter blocks on both sides. When the end of the paper contacts the adapter plate, the end of the paper will move along the arc surface of the adapter plate to the depth of the paper feed end.

[0015] Step four: Make the adapter block and the adapter plate fit tightly together through the connecting end so that the side or edge of the paper cannot enter the gap between the adapter block and the adapter plate, thereby avoiding paper jams. Combined with the inclined setting of the relative surface of the adapter block, the lower end of the arc surface of the adapter block is away from the paper to avoid contact with the paper and avoid paper jams.
