Description

[Brief explanation of the drawing]

Figure 1 is a schematic diagram of the main parts of a printer, - Figure 2 shows a conventional linear pulse smoker, Figure 2a is a sectional view, Figure 2 is a front view, and Figure 3 is a perspective view of a conventional stator. Figure, Figure 4a,
Figure 5b shows the case where the tooth width of the conventional stator and the slider are equal, and Figures 5a and b show the case where the tooth width of the conventional stator is wider than the tooth width of the slider. Figure 6a,
b and c are diagrams showing the displacement suppressing means of the mover of a conventional linear pulse motor, FIGS. 7a and 8a are front views showing the structure of the linear pulse motor according to the present invention, and FIG. , Fig. 8 is a diagram showing how when an external force is applied to the linear pulse motor shown in Figs. 7a and 8a, the mover is displaced, but a restoring force immediately acts. Figures 10a and 11a are diagrams showing the structure of the stator of the linear pulse motor according to the invention; Figures 10a and 11a are views showing the first modified embodiment of the invention; Diagrams showing how restoring force is generated in the example, Fig. 12 a, b
13 is a diagram showing a linear pulse smoker according to the present invention in which the stator is constructed of a laminated plate, and FIG. 13 is a diagram showing a state in which auxiliary means are attached to the present invention. In the drawings, 1 is a mover, 2 is a roller, 5 is a flange, 6 is a stator, 7 is a groove, 14 is a ball, 23° 23a, 23
b, 23C are stator teeth, 24 are grooves, 40.40a, 4
0b and 40C indicate the teeth of the mover, respectively.

Claims (1)

[Scope of utility model registration request] consisting of a stator having teeth arranged at a predetermined pitch, and a mover having teeth arranged at a pitch different from the pitch and facing the teeth of the stator, and equipped with electromagnetic means for exciting the teeth, In a linear pulse motor in which the movable element performs linear motion relative to the stator by controlling excitation of the electromagnetic means, each tooth of the stator has non-magnetic ends at both ends in a direction perpendicular to the direction of movement of the movable element. In addition, when the face width of the mover in the direction perpendicular to the moving direction of the mover is 11 and the face width of the stator is L, the structure is configured such that l≧L holds true. Linear pulse motor.
