[0016] See also Figure 1 and Figure 2, this embodiment discloses a state detection device for a passbook printer ribbon and a ribbon transmission mechanism, including a marking unit and a sensor unit 3. The marking unit is connected to the ribbon transmission mechanism for driving the movement of the ribbon, and moves or stops with the ribbon transmission mechanism. The sensor unit 3 is set by a fixing device to detect toward the marking unit, so as to obtain the real-time movement state of the ribbon transmission mechanism and the ribbon by detecting the marking unit, and send the detection information to the upper control system. The fixing device is a fixing plate 2 with a through hole 4, and the sensor unit 3 is fixed on the fixing plate 2. The fixing plate 2 is fixed to the ribbon transmission mechanism by bolts passing through the through hole 4 and cooperating with nuts, and the sensor unit 3 is directed toward the marking unit, wherein the bolts and nuts are not shown as a schematic diagram. Figure 1 As shown in the figure, those skilled in the art can understand based on common knowledge in the art that bolts pass through the through holes 4 and other corresponding fixing parts to cooperate with nuts for fixing.
[0017] In this embodiment, the marking unit is a marking gear 1 with a marking pattern on its surface. The ribbon transmission mechanism is a ribbon transmission gear set, and the marking gear 1 is meshed with a gear in the ribbon transmission gear set, so that the ribbon transmission mechanism moves or stops. The ribbon transmission gear set in this embodiment is an existing transmission mechanism in a passbook printer, including Figure 1 The two ends of the middle part are respectively provided with a ribbon transmission shaft 6 of a first ribbon transmission gear 5 and a second ribbon transmission gear 7, and a fourth ribbon transmission gear 9 connected to the second ribbon transmission gear 7 through a third ribbon transmission gear 8. When these gears move, they will drive the ribbon 10 below to move through a series of transmission structures. The marking gear 1 of this embodiment is meshed with the first marking gear 1 to achieve linkage. In actual use, the marking gear 1 can also be set to mesh with other ribbon transmission gears as needed. It should be understood by those skilled in the art that such modification is also included in the protection scope required by the utility model.
[0018] In this embodiment, the sensing unit 3 is a photoelectric sensor, which detects the marking pattern on the marking gear 1. The marking pattern rotates or stops with the marking gear 1, so that the photoelectric sensor obtains the motion state of the ribbon transmission mechanism gear. Specifically, the marking pattern in this embodiment is a black and white pattern, and the photoelectric sensor is a reflective photoelectric sensor. The detection head of the reflective photoelectric sensor is fixed and detects toward the marking gear 1, so that when the marking gear 1 rotates, a high and low level signal is generated due to the alternating appearance of black and white in front of the detection head, and a level signal without change is generated when the ribbon transmission mechanism gear stops.
[0019] The basic detection principle of the utility model is to spray black and white blocks on the marking gear 1, and at the same time add a fixed plate 2 in the position facing the black and white blocks. A reflective photoelectric sensor is installed on the fixed plate 2. When the ribbon transmission mechanism is in motion, the photoelectric sensor detects the change of the black and white blocks, thereby converting the change of the light signal into a change of high and low levels and outputting it to the main control board. If there are continuous changes in high and low levels, it means that the ribbon is operating normally. When the ribbon and the ribbon transmission mechanism work abnormally, the transmission mechanism does not work, and the photoelectric sensor cannot detect the change of the black and white area. Therefore, if the detection output level signal is continuously high or continuously low, it means that the ribbon is not operating normally.
[0020] The first ribbon transmission gear 5 in this embodiment is connected to the passbook printer carriage motor mechanism. When printing, the carriage motor moves horizontally to drive the ribbon transmission gear set, and then drives the ribbon to move.
