[0020] The first transition channel 130 is provided with a first driving conveyor belt 131 on one side and a first driven conveyor belt 132 on the other side. Through the tensioning of the first driving conveyor belt 131 and the first driven conveyor belt 132, they cooperate with each other. A first transition channel 130 that can convey banknotes is formed. The first transition channel 130 and the first transmission channel 120 are at a certain angle, and the direction of the banknotes will be changed greatly when the banknotes are transported here, which can easily cause banknote jams. Therefore, preferably, a guide plate 151 is provided at the junction of the first transition channel 130 and the second transmission channel 120, the function of which is to enable the banknote to be turned smoothly during the turning process and prevent the banknote from jamming.
[0021] One side of the second transmission channel 120 is provided with a second driving conveyor belt 121, and the first side is the aforementioned first driven conveyor belt 132. Through the tension of the second driving conveyor belt 121 and the first driven conveyor belt 132, they cooperate with each other. A second transport channel 120 that can transport banknotes is formed. One end of the second transmission channel 120 is connected to the first transition channel 130, and the other end is respectively connected to a medium outlet 130a and the second transition channel 140. A guide plate 152 is provided under the second transmission channel 120, and the guide plate 152 is substantially arranged along the entire second transmission channel 120 to prevent the unclamped banknotes from being unstable during the transportation process, thereby preventing banknote jams. . A commutator 141 is provided where the second transmission channel 120 is connected to the medium output port 130a and the second transition channel 140. The commutator 141 is controlled by an electromagnet or other driving elements to be rotatable. The connected tension spring or other elastic elements return to the initial position. The diverter 141 cooperates with the second active conveyor belt 121 to turn the banknotes into the second transition channel 140, and the other end of the second transition channel 140 can be connected to a banknote storage device (not shown) . A guide plate 153 is arranged above the diverter 141, and the diverter 141 cooperates with the guide plate 153 to guide the banknotes to the medium output port 130a.
[0022] One side of the second transition channel 140 is the aforementioned second driving conveyor belt 121, and the other side is the second driven conveyor belt 142. The second driving conveyor belt 121 and the second driven conveyor belt 142 are tensioned and formed in cooperation with each other The second transition channel 140 that can transport banknotes.
[0023] Combine figure 1 with figure 2 The sheet-type medium transport mechanism 100 of this embodiment further includes multiple sets of conveyor pulleys. The first driving belt 131, the second driving belt 121, the first driven belt 132, and the second driven belt 142 are respectively wound on the corresponding set of belt wheels. Specifically, the first driving belt 131 is wound around the first belt wheel 161, the second driving belt 121 is wound around the second belt wheel 162, and the first driven belt 132 is wound around the third belt wheel 163. Above, the second driven conveyor belt 142 is wound on the fourth conveyor belt wheel 164.
[0024] Preferably, since the banknotes are transported through the conveyor belt in the second transmission channel 120, the first transition channel 130 and the second transition channel 140, to achieve the ideal transport effect, the aforementioned active conveyor belts 131, 121 and driven conveyor belts 132, 141 must A squeezed state is formed, and the distance between the two sets of conveyor pulleys is not less than the width of the banknote to be conveyed.
[0025] Refer now figure 1 The working principle of the sheet-type medium transport mechanism 200 of this embodiment is described. Sheet-type media, such as banknotes, are guided from the media input port 110a into the first transmission channel 110 of the sheet-type medium transmission mechanism 200 by the guide piece 155. The transmission group wheel is driven by the motor to rotate, thereby driving each pair of The sheet-like medium between the conveying wheels moves forward along the first conveying channel 110. When the sheet-like medium reaches the end of the first conveying channel 110, its direction changes and passes into the first transition channel. 130. It is transported by the first main conveyor belt 131 and the first slave conveyor belt 132 until it enters the second transport channel 120. In the second transport channel 120, the second driving conveyor belt 121 and the first driven conveyor belt 132 clamp the sheets The medium continues to move along the transmission channel to the end of the second transmission channel 120. If the sheet-like medium is an abnormal medium, such as a counterfeit banknote, the commutator 141 is deflected downward under the control of an electromagnet or other driving elements to close the passage of the normal medium, so that the abnormal medium moves along the upper and lower sides of the commutator 141. The channel under the guide plate 153 is sent to the medium output port 130a, and then the commutator 141 automatically returns to the initial position under the action of the restoring force of the spring or other driving elements. If the sheet medium is a normal medium, it enters the second transition channel 140 along the smooth arc at the bottom of the commutator 141, and is conveyed to the medium storage device by the second driving belt 121 and the second driven belt 142 (Figure Not shown).
[0026] It should be noted that the sheet-type medium transmission mechanism of the present invention is not limited to having two transmission channels, and the number of transmission channels can be set as required; the sheet-type medium transmission mechanism of the present invention can not only be applied to the aforementioned bank teller machine, but also Other sheet media, such as printing paper, ticket processing equipment, etc.; the distance of the conveying group wheel can be changed according to the width of the conveyed medium, so as to facilitate the conveying of various sizes of sheet media.
