  Next, the best embodiment according to the present invention will be given and described in detail with reference to the drawings.

  First, a schematic configuration of a suitable ticketing machine M using the magnetic processing unit mounting mechanism 1 according to the present embodiment will be described with reference to FIG.

  Reference numeral 31 denotes a cabinet, which has a ticketing slot 32 at the lower front portion of the cabinet 31 and an operation panel 33 above the ticketing slot 32. Further, a main body chassis 3 is disposed inside the cabinet 31, and a stacker unit in which the main body chassis 3 accommodates ticket bodies Sca (Sc)... Scb (Sc). 35a and 35b, main processing units such as a magnetic processing unit Mm, a printing unit 37, and the like, and a plurality of transporting rollers and a transport along the stacker units 35a and 35b, the magnetic processing unit Mm, the printing unit 37, and the ticket opening 32.

To do. The magnetic processing unit Mm can be detachably attached to the main body chassis 3 using the attachment mechanism 1 according to the present embodiment.

  Next, the configuration of the attachment mechanism 1 according to the present embodiment will be specifically described with reference to FIGS.

  First, as shown in FIG. 1, an opening 3w that accommodates the magnetic processing unit Mm is formed in the main body chassis 3 in which the magnetic processing unit Mm is installed. Since the magnetic processing unit Mm includes the unit-side chassis 2 as described above, the opening 3w is selected to have a size that allows the unit-side chassis 2 to completely enter the inner space of the opening 3w. The shape of the opening 3 w is selected in consideration of the outer shape of the unit-side chassis 2. In particular, it is desirable to consider the size and shape of the opening 3w so that the magnetic processing unit Mm can be mounted and removed smoothly.

  On the other hand, when the unit-side chassis 2 included in the magnetic processing unit Mm is accommodated in the opening 3w as shown in FIG. 3, the transport path Fm of the unit-side chassis 2 becomes the transport path Fo, It is desirable to use the same material as the main body chassis 3 and to have the same thickness so as to be located on the same plane with respect to Fo. Thereby, when the magnetic processing unit Mm is attached to the main body chassis 3, a functionally continuous transport path F for transporting the bills Sc is formed between the magnetic processing unit Mm and the main body chassis 3.

  For this reason, as shown in FIG. 1, at both ends of the unit-side chassis 2, transport path forming portions 2f and 2f for forming the transport path F are provided, and the main body chassis 3 is provided with the transport path forming portions 2f and 2f. Opposing transport path forming portions 3f and 3f are provided. Further, as shown in FIG. 3, the front end portions 2e, 2e, 3e, and 3e of the respective conveyance path forming portions 2f, 2f, 3f, and 3f are slightly bent inward to ensure smooth conveyance of the bill body Sc. To do.

  Furthermore, the attachment position when attaching the unit side chassis 2 to the main body chassis 3 is selected. In the example, if the unit-side chassis 2 is regarded as a horizontally long rectangle, the lower left side position, the lower right side position, and the upper long side center position have three attachment positions Pa, Pb, and Pc, respectively. Can be selected. The main body chassis 3 and the unit-side chassis 2 at the mounting positions Pa, Pb, and Pc are provided with notches 3c and 2c, respectively. In this case, as shown in FIGS. 1 and 5, the cutout portion 3 c provided in the main body chassis 3 is formed in a semicircular shape from the end side portion of the main body chassis 3, and the cutout portion 2 c provided in the unit side chassis 2 is A U-shape is formed from the end side of the side chassis 2.

The three sets of fixtures 4 are the same, and the set of fixtures 4 includes a first fixed body 11 disposed on one surface of the main body chassis 3 and the unit side chassis 2, and the main body chassis 3 and the unit side chassis. 2, a second fixing body 12 disposed on the other side surface, and a first fixing body 11 and a fixing screw portion 13 for fixing the second fixing body 12. As shown in FIG. 2, the first fixed body 11 is formed in a disk shape having a certain thickness, and an engaging projection 11s is integrally formed on one end surface side, and a screw hole 11n is provided in the center. . In this case, the cross section of the engaging protrusion 11s is formed in an oval shape as shown in FIG. That is, it has a shape obtained by slicing a 180 [°] facing position on a cylindrical outer peripheral surface into a D-cut shape. And the dimension between these slice surfaces is made to correspond substantially with the width dimension of the notch part 2c formed in the U shape mentioned above. Further, the curvature of the arc surface other than the slice surface in the engaging protrusion 11s is made to substantially coincide with the curvature of the notch 3c formed in the semicircular shape described above.

  Therefore, as shown in FIG. 5, the engaging protrusion 11s can be engaged with each of the notches 2c and 3c, and the engaging protrusion 11s is in the longitudinal direction of the notch 2c. Therefore, the engaging protrusion 11s and the notch 2c are allowed to be displaced relative to each other only in one direction. Thereby, since the rotation prevention of the 1st fixing body 11 is performed, the improvement of the attachment property and operativity of the fixing tool 4 is achieved. Further, if the clearance in the regulated direction of the engaging protrusion 11s and the notch 2c is reduced as much as possible, the main body chassis 3 can be positioned with respect to the unit-side chassis 2. That is, as described above, the three attachment positions Pa, Pb, and Pc are arranged at the lower position of the left short side, the lower position of the right short side, and the center position of the upper long side, respectively, in the unit-side chassis 2. The unit-side chassis 2 is positioned by being regulated by the X-direction position and the Y-direction position. Thereby, in addition to the fixing function (attachment function) by the plurality of fixtures 4..., The positioning function can be used together, which can contribute to further simplification of the mechanism structure of the attachment mechanism 1.

  Further, as shown in FIG. 2, the second fixed body 12 is formed in a disk shape having a certain thickness, and the distal end portion of the engaging protrusion 11 s enters and engages (fits) on one end surface side. Engaging recess 12r is provided. Thereby, positioning of the 1st fixed body 11 and the 2nd fixed body 12 can be performed easily and reliably. A screw insertion hole 12h is provided at the center. The diameter of the second fixed body 12 is set larger than the diameter of the first fixed body 11. On the other hand, the fixing screw portion 13 has a screw portion main body that is screwed into the screw hole 11n described above, and is attached with a washer and a ring-shaped spring.

  As described above, the fixture 4 is arranged on the one side surface of the main body chassis 3 and the unit side chassis 2, and the second side is arranged on the other side surface of the main body chassis 3 and the unit side chassis 2. If the fixing body 12 and the fixing screw portion 13 that fixes the first fixing body 11 and the second fixing body 12 are provided, the mounting mechanism 1 according to the present embodiment can be simplified by the mechanism structure. A greater effect can be obtained from the viewpoint of cost reduction and efficiency improvement of replacement work. Moreover, the main body chassis 3 and the unit-side chassis 2 are provided with notches 3c and 2c, respectively, and the first fixed body 11 is provided with an engaging protrusion 11s that can be engaged across the notches 3c and 2c. Since they are provided integrally, it is possible to improve the attachment and operability of the fixtures 4... And obtain a greater effect from the viewpoint of increasing the efficiency of replacement work of the magnetic processing unit Mm.

  Next, an attachment method and a removal method of the magnetic processing unit Mm using the attachment mechanism 1 according to the present embodiment will be described with reference to each drawing.

As shown in FIG. 2, the set of fixtures 4 includes the first fixed body 11, the second fixed body 12, and the fixing screw portion 13. As shown in FIG. 5, the notch 2c of the unit side chassis 2 in the magnetic processing unit Mm is accommodated from one surface, and further from the other surface to the front end of the engaging projection 11s. The engaging recess 12r of the two fixed body 12 is engaged. Then, as shown in FIG. 2, the fixing screw portion 13 is screwed into the screw hole 11 n of the first fixing body 11 through the insertion hole 12 h of the second fixing body 12. The engaging protrusion 11s is inserted to the bottom of the notch 2c, and in this state, the fixing screw 13 is tightened to temporarily fix the fixture 4 so as not to fall on the unit-side chassis 2. The above temporary fixing is similarly performed for the other fixing devices 4.

  The unit-side chassis 2 of the magnetic processing unit Mm can be accommodated in the opening 3w of the main body chassis 3 in this state, so that the hand is positioned in the gap W provided in the unit-side chassis 2 and the main body chassis 3. The processing unit Mm is held, and in this state, the three fixing devices 4 are properly fixed. That is, the fixing screw portion 13 is slightly loosened, the fixing tool 4 is slid in the direction in which the engaging protrusion 11s is moved out of the notch 2c, and the engaging protrusion 11s is engaged with the notch 3c of the main body chassis 3. . At this time, the engaging protrusion 11s is brought into contact with the bottom of the notch 3c. This state is shown in FIGS. The above procedure is similarly performed for the other fixtures 4. When the three sets of fixtures 4 are set in the same state, the fixing screw portions 13 are completely tightened while balancing the tightening degrees of the three sets of fixtures 4. At this time, since the engaging protrusion 11s is engaged with the notch 2c and is prevented from rotating, the fixing screws 13 can be tightened or loosened without pressing the first fixed body 11.

  Thereby, the magnetic processing unit Mm can be attached to the main body chassis 3. As described above, when attaching the magnetic processing unit Mm to the main body chassis 3, it is possible to easily perform the attaching work by one person without using a tool (a jig). On the other hand, when detaching the magnetic processing unit Mm from the main body chassis 3, the work may be performed in the opposite procedure to the above-described procedure for attachment. As described above, when the magnetic processing unit Mm is attached to the main body chassis 3, a functionally continuous transport path F for transporting the bills Sc is formed between the magnetic processing unit Mm and the main body chassis 3. The

  Thus, according to the magnetic processing unit attachment mechanism 1 according to the present embodiment, the main body chassis 3 is formed with the opening 3w for accommodating the magnetic processing unit Mm, and the magnetic processing unit Mm is provided with the opening 3w. A unit-side chassis 2 having a transport path Fm (F) located on the same plane with respect to the transport path Fo (F) of the main chassis 3 when provided is provided, and a plurality of units between the unit-side chassis 2 and the main chassis 3 are provided. The mounting positions Pa, Pb, and Pc are fixed between the unit side chassis 2 and the main body chassis 3 and fixed by the fixtures 4 that sandwich the unit side chassis 2 and the main body chassis 3 from both sides. The position accuracy of the magnetic processing unit Mm relative to the ticket body Sc can be increased. As a result, even if it is required that the permissible error with respect to the position in the width direction is 0.05 [mm] or less, it is possible to sufficiently cope with the occurrence of an error such as a reading defect with respect to the ticket body Sc. Can be avoided. Further, a plurality of mounting positions Pa, Pb, Pc between the unit side chassis 2 and the main body chassis 3 are straddled between the unit side chassis 2 and the main body chassis 3, and the unit side chassis 2 and the main body chassis 3 are sandwiched from both sides. Since fixing is performed by the fixtures 4..., The cost can be reduced by simplifying the mechanism structure of the attachment mechanism 1, and further, the efficiency of replacement work when replacing the magnetic processing unit Mm can be improved. Moreover, since the magnetic processing unit Mm is applied to the magnetic processing unit for performing recording or reading on the magnetic recording surface Scm of the ticket body Sc by attaching the magnetic processing unit Mm to the main body chassis 3 of the ticket issuing machine M, the mounting mechanism 1 according to the present invention is implemented.
