CN204566953U 一种打印机纸边检测装置 有权

一种打印机纸边检测装置
摘要：
本实用新型提供一种打印机纸边检测装置，包括机架，以及设于机架上的打印头，位于打印头下方的机架上设有水平进纸通道，水平进纸通道上设有送纸辊，送纸辊的辊轴与驱动电机相连接，其特征在于水平进纸通道的输出端设有一前一后两个压纸档板，并在两个压纸挡板之间的进纸通道一侧或两侧设有凹槽型光电传感器。简化了光电检测结构，只需通过单个凹槽型光电传感器对打印纸张的纸边进行检测，就可根据检测信号使打印机控制系统驱动打印头将打印内容准确打印在纸张上。这样不仅简化了打印机光电检测部分的结构，而且使用单一结构的光电元件也提高了设备的耐久性和可靠程度。另外，简化后的结构对成本控制也大有帮助。
摘要（英）：

The utility model provides a device for printer paper margin is detected, including the frame to and locate the printer head that beats in the frame, be equipped with horizontal paper feed passageway on lieing in the frame of beating the printer head below, be equipped with the roller of form advancing on the horizontal paper feed passageway, the roller of the roller of form advancing is connected with driving motor, the output of the horizontal paper feed passageway of its characterized in that is equipped with two tandem and presses the paper plate washers, and on one side of two paper feed passageways of pressing between the paper baffle or both sides be equipped with fluted body photoelectric sensor has simplified the photoelectric detection structure, has only needed to detect the paper margin of printing the paper through singly individual fluted body photoelectric sensor, just can make the drive of printer control system beat printer head according to the detected signal and will print the accurate printing of content on the paper so not only simplified the structure of printer photoelectric detection part, the photounit that uses single structure has in addition also improved durability and the degree of reliability of equipment in addition, the structure after the simplification is also very helpful to the cost control
