Description

[Detailed description of the invention] This invention relates to the installation of a paper cutter of a printing device used in cash registers, etc., and relates to a mounting device that allows the paper cutter to be installed quickly and reliably with simple work. It is something.

In cash registers, etc., numerical values such as amounts and data, calculation results, etc. are displayed on the display device, and the printed paper is printed on a piece of paper and handed to the customer as a receipt, or the printed piece of paper is cut to save it for records. There is a need. For this purpose, a paper cutter device is provided in the printing device and has a structure in which the paper cutter device cuts the printed paper by pulling it in a specified direction.

Conventionally, such paper cutter devices have been made of synthetic resin, metal, or the like, and fixed to a cover or the like with screws, welding, or the like. However, with the above-mentioned installation method, the work of fixing the paper cutter to the cover etc. is complicated and requires a lot of man-hours.Especially, when the paper cutter is attached by welding etc., replacing the paper cutter is only necessary for the paper cutter. In addition, the cover and the like had to be replaced at the same time.

The present invention eliminates the above-mentioned drawbacks and provides an attachment device that can reliably attach a paper cutter to a cover with simple operations.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a perspective view of an embodiment of the member mounting device according to the present invention, and FIG. 2 is an exploded perspective view of the same member mounting device. In the figure, reference numeral 1 denotes a cover that covers equipment such as a printing device, and has a structure that is attached to a main body of the equipment (not shown) with a locking claw 3 and a locking piece 4. 2 is a paper cutter, cover 1
is inserted into.

As shown in FIG. 2, the cover 1 is surrounded by an inclined opening surface 5 having a width equal to or slightly wider than the width of the paper cutter 2, and portions of both sides connected to the opening surface 5. It has an opening.
Then, step portions 8 for supporting the paper cutter 2 upward are formed on each side excluding the above-mentioned portions of both sides and on the side facing the opening surface 5. A locking opening 9 is formed in the side wall of the stepped portion 8 on the side. In addition, a stepped recess 6 from the back surface is formed on a portion of both sides connected to the opening surface 5 so as to be approximately flush with the stepped portion 8, and a recess 7 is formed in the same direction as the stepped recess 6. Form.

On the other hand, the paper cutter 2 is formed with a blade part 12, and has locking pieces 10 protruding outwardly at appropriate positions on both sides connected to the blade part 12, and locking pieces 10 protruding outwardly on the sides facing the blade part 12. A protruding locking claw 11 is formed. In the above-described configuration, when the paper cutter 2 is inserted into the cover 1, the recess 7 and the locking piece 10 have corresponding shapes and are set at corresponding positions. Mouth 9 and locking claw 1
1 are also set in corresponding shapes and positions.

Next, the procedure for inserting a component in the component mounting device of the present invention will be described with reference to Fig. 3. Fig. 3 is a diagram for explaining the procedure for inserting a component in the component mounting device of the present invention, with Fig. 3a showing the start of insertion, Fig. 3b showing the middle of insertion, and Fig. 3c showing the completion of insertion. In the diagram, the paper cutter 2 is inserted in the direction of arrow A through the opening surrounded by the opening surface 5 and both side edges from the back surface of the cover 1 with the locking claw 11 facing upward. Then, as the paper cutter 2 is inserted, it is rotated in the direction of arrow B. In this case, the paper cutter 2 rotates around the edge of the step 8, and the paper cutter 2 is inserted sufficiently in the direction of arrow A, that is, if the locking piece 10 of the paper cutter 2 is inserted so as to abut against the step recess 6, the blade 12 of the paper cutter 2 enters the opening without touching the opening surface 5, as shown in Fig. 3b.

On the other hand, in this state, the locking piece 10 of the paper cutter 2 is in contact with the stepped recess 6,
Therefore, the lower surface of the paper cutter 2 and the upper surface of the stepped portion 8 are not in a parallel state, and the locking claw 11 of the paper cutter 2 is in a state floating above the stepped portion 8. Therefore, as shown in Figure b, pressure is applied near the locking claw 11 of the paper cutter 2 in the direction of arrow C.
Place the paper cutter 2 and the stepped portion 8 in a parallel state, apply force in the direction of arrow D, slide the paper cutter 2 on the stepped portion 8, and insert the locking claw 11 into the locking opening 9. do. At the same time as the locking claw 11 is fully inserted into the locking opening 9, the locking piece 10 of the paper cutter 2 is fitted into the recess 7 of the cover 2, and the paper cutter 2 is in a state substantially parallel to the stepped portion 8. Complete insertion. That is, the state shown in FIG.

As described above, the member mounting device according to the present invention is the third
As shown in Figure b, this method takes advantage of the bending of the member (paper cutter in the explanation) attached to the cover, etc., and fixes it with a locking piece and a locking claw. Moreover, it is easy to fix without any tools or the like. It can be inserted and installed with some effort. These techniques according to the present invention are not limited to paper cutters and can be applied to various other applications without changing the gist of the present invention.

Note that when the member is to be removed from the cover or the like, it can be easily done by reversing the above-described procedure for attaching the member.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of an embodiment of the member mounting device according to the present invention. FIG. 2 is an exploded perspective view of the member mounting device. Fig. 3 is a sectional view (cross section taken along line A-A' in Fig. 2) for explaining the procedure for inserting a member in the member mounting device, and Fig. 3a shows the start of inserting the member; Figure b shows the member being inserted in the middle, and figure c shows the completed member insertion. In the figure, 1 is the cover, 2 is the paper cutter, 6
