Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a magnetic head device, and more particularly to a device capable of detecting whether or not a magnetic head is set at an accurate position.
[0002]
[Prior art]
Conventionally, a magnetic head device incorporated in a magnetic ticket processing machine such as an automatic ticket checker or an automatic checkout machine has a magnetic head between a magnetic head and a pinch roller for maintenance inspection such as cleaning of the magnetic head and discharging of a jam ticket. Is configured to be expanded as needed.
[0003]
Figure 2 is a side view der the magnetic head device B that are incorporated in a conventional automatic ticket gate is, FIG. 2, FIG. 3 to be described later (a), corresponding to a view from the bottom, respectively (b) you are. This magnetic head device B is configured by providing a magnetic head H and a pinch roller P on a frame F attached to a card handler of an automatic ticket checker (not shown). Among these, the magnetic head H is fixed to the frame F by screws.
[0004]
The pinch roller P is provided on the movable piece 1 that is provided on the frame F so as to be rotatable via the support shaft 1a. That is, the pinch roller P is provided on the movable piece 1 through the support shaft 2 so as to be rotatable, and a magnetic ticket or the like that is conveyed in the direction indicated by the alternate long and short dash line on the magnetic head H by a conveying mechanism (not shown). A predetermined pressing force can be applied to a magnetic card (not shown).
[0005]
The movable piece 1 is configured such that when the knob 3 is pulled, the lock is released and the movable piece 1 can be rotated around the support shaft 1a as shown by a two-dot chain line in FIG. Therefore, when the movable piece 1 rotates, the space between the magnetic head H and the pinch roller P is widened, and maintenance inspection becomes possible.
[0006]
3 (a) and 3 (b) show the relationship between the movable piece 1 and the knob 3, wherein (a) shows the state of the movable piece 1 at the solid line position in FIG. The movable piece 1 is shown in a movable state indicated by a two-dot chain line.
[0007]
The knob 3 is provided so that the shaft 3a of the knob 3 passes through the movable piece 1 so as to be movable , and the tip 3b of the shaft 3a is located on the frame F side and is a recess provided in the frame F. 4 is configured so that it can be inserted.
[0008]
In FIG. 3, reference numeral 5 denotes a spring that acts so that the knob 3 is always attracted to the movable piece 1 side, that is, the tip 3 a of the knob 3 is always projected toward the concave portion 4, Reference numeral 4 a denotes an air vent hole when the tip 3 b of the shaft 3 a is inserted into the recess 4, and is provided through the portion of the frame F where the recess 4 is provided. The air vent 4 a is provided in a direction that coincides with the axial direction of the shaft 3 a of the knob 3 when the tip 3 b of the knob 3 is inserted into the recess 4 .
[0009]
The shaft 3a of the knob 3 is colored vermillion, for example, so as to be different from the surrounding color of the movable piece 1 or the frame F, so that the state when the knob 3 is pulled can be easily seen, The state where the pinch roller P is not normally set can be easily seen.
[0010]
[Problems to be solved by the invention]
However, although the conventional magnetic head device is configured so that the state in which the knob is pulled can be visually observed by coloring the shaft, forgetting to set the pinch roller may occur after the maintenance inspection of the magnetic head device is completed. In this state, the operation of the magnetic ticket processing machine such as an automatic ticket gate is started, which may cause inconvenience in the magnetic ticket processing.
[0011]
The present invention, which was made to solve the above drawbacks, and its object is provide a magnetic head apparatus that can detect whether the magnetic heads is set correctly There is to do.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, a magnetic head device according to the present invention includes a magnetic head fixed to a frame, a movable piece rotatably provided with respect to the frame, and a magnetic ticket or a magnetic A pinch roller that is rotatably provided on the movable piece that presses the card, a knob that is movably provided on the movable piece with the end of the shaft positioned on the frame side, and the pinch roller that is provided with the magnetic A recess provided in the frame into which the tip of the shaft is inserted at a position where a bill or a magnetic card is pressed against the magnetic head, and an axis of the shaft when the tip of the shaft is inserted into the recess The air vent hole that is aligned with the direction and penetrates the frame where the concave portion is located, and is provided movably in the air vent hole, and the tip of the shaft is inserted into the concave portion To its recess One end of the shaft is pushed out of the recess at the tip of the shaft, and when the tip of the shaft comes out of the recess, the one end is positioned in the recess, and the pin And a switch fixed on the frame side operated on the other end side .
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a magnetic head device A according to an embodiment corresponding to FIG. In addition, the same code | symbol is used for the same component as the said conventional, and since description overlaps about these component elements, a different code | symbol is attached | subjected and demonstrated about a new component element.
[0014]
In the figure, 10 is a pin, provided so as to be movable in the d A vent holes 4a, one end is located in the recess 4, the other end is provided in the mounting piece 11 side provided on the frame F ing. The pin 10 is located in the mounting piece 11 side, have a spring 12 is provided, one end of the pin 10 is configured to so that can contact at all times and the distal end portion 3b side when inserted into the recess 4 ing. The strength of the spring 12 is determined to be sufficiently smaller than the strength of the spring 5 so as not to move the knob 3.
[0015]
On the other end side of the pin 10 (on the side opposite to the one end side positioned on the concave portion 4 side ), a switch 13 composed of a limit switch fixed on the frame F side is provided, and a lever 13a of the switch 13 is connected to the pin 10. Is in contact with the other end . Therefore, when the pin 10 moves through the air vent hole 4a, the lever 13a moves from the solid line position shown in the figure to the two-dot chain line position, and the switch 13 can be operated.
[0016]
In the above configuration, when the pinch roller P (see FIG. 2) is normally set after completion of the maintenance inspection , one end of the pin 10 is pressed by the tip 3b of the shaft 3a of the knob 3. When one end of the pin 10 is pushed down by the tip 3b of the shaft 3a, the pin 10 moves and the lever 13a is pushed down at the other end of the pin 10 , and the pinch roller P is normally set from the switch S. A signal to the effect is input to a controller (not shown) of a magnetic ticket processing machine (or an automatic ticket gate controller if the magnetic ticket processing machine is an automatic ticket gate).
[0017]
On the other hand, when the pinch roller P is not set correctly, that is, even after maintenance and inspection, when the pinch roller P is in the position indicated by the two-dot chain line in FIG. 2, the lever 13a of the switch 13 is pressed by the other end of the pin 10. Since this is not done, the switch S outputs an unset signal to the controller. Then, the controller displays a message indicating that the setting has not been completed on a display (not shown) (in the case where the magnetic ticket processing machine is an automatic ticket gate), the display is incomplete. Therefore, the clerk can deal with the set failure promptly.
[0018]
