Patent number: 11926149Abstract: A printer includes a paper roll, a printing device, a paper cutting device, a paper output device, and a panel, which are disposed, from rear to front in sequence, on a frame. The printing device includes a printer seat on which a printer head, a paper delivering roller, and a guiding member are disposed. The guiding member forms a paper insertion gap between a guiding piece and a printer seat. The paper insertion gap can smoothly guide a front end of a paper sheet to be inserted downwards to contact with a paper delivering roller. Then, the guiding member pivots back to a positioned state. Thus, the paper sheet can be conveniently and rapidly installed. A paper guiding gap is formed between at least one guiding roller and the printer seat. The paper delivering roller can reliably pull the paper sheet to pass through a printer head for printing.Type: GrantFiled: March 31, 2022Date of Patent: March 12, 2024Assignee: Top Vending Machine Electronics Co., Ltd.Inventor: Yuan-Fong Chang
