  In particular, the case 60 is assembled to the housing 11 such that the end portion including the reading port 13 of the reading portion 11c at the time of engagement passes through the annular portion 62. Thereby, even when the reading port 13 needs to be read close to the barcode B, the reading port 13 is prevented from becoming difficult to approach the barcode B due to the annular portion 62 assembled in the vicinity of the reading port 13. it can.

  The case 60 may be engaged with the housing 11 at a location different from the reading unit 11c in addition to the engagement with the cable holding unit 11d, or may be engaged only with the cable holding unit 11d. Good.

  In addition, since the connecting portion 63 facing the grip portion 11e of the housing 11 when engaged is formed in a thin shape along the grip portion 11e, the case 60 has a bar code reader with the tag function restriction device 50 assembled thereto. When the user grips 10, the tag function restriction device 50 can be made difficult to obstruct gripping.

  The case 60 is not limited to being attached to the casing 11 by the above-described engagement with the cable holding portion 11d with the rear cover 14 removed from the casing 11, and other covers that close the opening formed in the casing 11. (For example, a battery replacement cover) may be attached to the housing 11 by using an engaging portion for engaging the other cover by removing or shifting the cover.

  In this case, the case 60 may be assembled to the casing 11 so as to be separated from the grip portion 11e of the casing 11. Even in this case, when the user grips the barcode reader 10 to which the tag function restriction device 50 is assembled, the tag function restriction device 50 can be made difficult to obstruct the grip.

[Second Embodiment]
Next, a tag function restriction device according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 7 is an external view showing a tag function restriction device 50a according to the second embodiment. 8A and 8B are side views for explaining the difference in shape between the two barcode readers.

  The tag function restriction device 50a shown in FIG. 7 is configured so as to be able to be attached to the barcode reader 90 shown in FIG. 8B in addition to the barcode reader 10 shown in FIG. 8A. The bar code reader 90 is another series of the bar code reader 10, and as can be seen from FIG. 8, the rear cover 93 has a full length direction length L2 longer than the full length direction length L1 of the rear cover 14. In addition, the length in the full length direction of the opening 92 of the cable holding portion 91 is formed to be longer than the length in the full length direction of the opening 15 of the cable holding portion 11d. The bar code reader 90 and the bar code reader 10 are formed in substantially the same shape with respect to the outer casing of the other reading unit 11c and the like, both the engaging unit 16a, the guide 16b, the concave arc unit 15a, and the like. .

  For this reason, the cable holding portion 91 of the barcode reader 90 has an edge portion 91a that is equal to the edge portion 11f of the cable holding portion 11d of the barcode reader 10 by the length ΔL (= L2-L1) is formed so as to be displaced in the direction of the reading port 13. On the other hand, as with the rear cover 14, the rear cover 93 is formed with both engaging portions 14a, guides 14b, and concave arc portions 14c.

  By the way, if the case of the tag function restriction device is formed so as to be assembled to the barcode reader 10 from which the rear cover 14 has been removed, the edge 91a of the cable holding portion 91 is directed toward the reading port 13 by ΔL with respect to the edge 11f. Due to the deviation, when the rear cover 93 is assembled to the barcode reader 90, a gap is formed between the edge 91a of the cable holding portion 91 and the case, and dust or the like enters the opening 92. there is a possibility. On the other hand, when the tag function limiting device case is formed so as to be assembled to the barcode reader 90 from which the rear cover 91 has been removed, when the rear cover 14 is assembled to the barcode reader 10 from which the rear cover 14 has been removed, the edge portion 11f of the cable holding portion 11d. Will come into contact with the case, and the tag function limiting device cannot be shared.
