For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.
[0018] The present utility model will be further described below with reference to the drawings and specific embodiments.
[0019] As Figures 1 to 4As shown in the figure, a bill printing device applicable to narrow spaces in this embodiment includes an installation bracket 1. The outline of the installation bracket 1 is generally rectangular parallelepiped-shaped. A print head control board 2 and a control button board 3 are provided inside the installation bracket 1. The installation bracket 1 is installed on a guide rail 4. During maintenance, the installation bracket 1 is pulled out from the rear of the TVM through the guide rail for maintenance. A kidney-shaped hole 5 is provided at the front end of the installation bracket 1. The thermal print head 6 is installed on the installation bracket 1 through an adjustment stud 7. The adjustment stud 7 passes through the kidney-shaped hole 5. By adjusting the up and down position of the adjustment stud 7 in the kidney-shaped hole 5, the deformation of the guide rail 4 is compensated, and the centering of the thermal print head 6 and the paper outlet of the TVM in the up and down direction is achieved.
[0020] A roller 8 is rotatably provided at the upper end of the installation bracket 1. Two vertical plates 12 are provided at the upper end of the installation bracket 1. A roller groove 13 is provided on the vertical plates 12. Both ends of the roller 8 are installed in the roller groove 13. A printing paper 9 is sleeved on the roller 8. The printing paper is located at the top of the device. When replacing the printing paper, the roller is passed through the center of the printing paper, and then the roller is placed in the roller groove. At the paper inlet of the thermal print head 6, a paper inlet guiding member 10 is provided. At the printing port, two upper and lower paper outlet guiding plates 11 are provided. Both of the two paper outlet guiding plates 11 are inclined. The distance between the two paper outlet guiding plates 11 gradually decreases in the direction away from the thermal print head 6. When loading the printing paper, the printing paper is loaded into the thermal print head through the paper inlet guiding member. When printing and discharging paper, the printed bill is discharged through the paper outlet guiding plate.
