Abstract

A bar code reader includes a casing having an inner space for accommodating a plurality of internal components, and a bar code reader module disposed within the inner space of the casing for reading a bar code of a target object through a projection window provided to one side of the casing. A speaker module is disposed adjacently to the bar code reader module for generating the reading by the bar code reader module as a signal sound to send it to a speaker hole formed in the casing, and a module bracket integrally supports the bar code reader module and the speaker module for integrally assembling the bar code reader module and the speaker module to corresponding places within the casing. The bar code reader module and the speaker module are integrally supported using a single item to decrease the number of components and overall cost. Also, assembling can be simplified to reduce a loss conventionally caused by the increase of the components.

Claims

1. A bar code reader comprising:

a casing having an inner space for accommodating a plurality of internal components;

a bar code reader module disposed within the inner space of the casing for reading a bar code of a target object through a projection window provided to one side of the casing;

a speaker module disposed adjacently to the bar code reader module for generating the reading by the bar code reader module as a signal sound to send it to a speaker hole formed in the casing; and

a module bracket integrally supporting the bar code reader module and the speaker module for integrally assembling the bar code reader module and the speaker module to corresponding places within the casing.

2. The bar code reader of claim 1, wherein the module bracket comprises:

a first bracket portion for supporting by partially encompassing the bar code reader;

a second bracket portion extending from one side of the first bracket portion for supporting by partially encompassing the speaker module; and

a coupling portion disposed to either one of the first and second bracket portions, and forming a coupling path of a coupling member for coupling the module bracket to the casing.

3. The bar code reader of claim 2, wherein the module bracket is joined to a main Printed Circuit Board (PCB) disposed where the bar code reader module is disposed;

and

the first bracket portion comprises at least one hook for temporarily supporting the module bracket to the main PCB.

4. The bar code reader of claim 2, wherein the first bracket portion is shaped as a rectangular box having at least one side open;

and

the coupling portion is each formed to both sides of the first bracket portion.

5. The bar code reader of claim 2, wherein the casing and openings formed by the first and second bracket portions are each disposed toward the projection window and the speaker hole when the module bracket is assembled within the casing.

6. The bar code reader of claim 2, wherein the first and second bracket portions and the coupling portion is formed of a synthetic resin integrally injection molding.

7. The bar code reader of claim 3, comprising;

an input button coupled by being partially exposed from a hand-held unit formed to one side of the casing for supplying a reading operation signal;

an auxiliary Printed Circuit Board (PCB) disposed within the casing having the input button, and having a tact switch for generating pressing of the input button as an electrical signal; and

a connecting unit flexibly and electrically connecting the main PCB to the auxiliary PCB.

8. The bar code reader of claim 7, wherein the connecting part is a Flexible Printed Circuit Board (FPCB).

9. The bar code reader of claim 7, further comprising:

a top cover coupled to an upper surface of the casing to be assembled and dissembled, wherein the top cover is coupled with a power switch; and

a display unit is disposed around the power switch for sending whether the reading is performed or not by pressing the input button by an on/off flickering signal.

10. The bar code reader of claim 9, wherein the display unit comprises:

a first display window formed to the casing along a circumferential surface of the power switch;

a second display window formed to the casing, and separated from the first display window;

at least one Light Emitting Diode (LED) coupled to the main PCB for forming a light emitting power source;

a light guide plate for integrally connecting the first and second display windows to sent the light formed by the LED to both first and second display windows areas; and

a control unit for selectively controlling an on/off control of the LED based on whether the input button is operated or not.

11. The bar code reader of claim 10, wherein the control unit controls to turn on the LED by pressing the input button when the reading is performed, and turn off the LED by releasing the pressing of the input button when the reading is stopped.

12. The bar code reader of claim 6, wherein the casing comprises front and rear side casings, which can be mutually assembled and dissembled;

and

a projection window protecting rim coupled to the projection window region when the front and rear side casings are assembled to each other.

13. The bar code reader of claim 12, wherein the projection window protecting rim is formed of an elastic substance retaining a buffering force.

14. The bar code reader of claim 13, wherein a plurality of catch hooks are formed to either one of the projection window protecting rim and an edge of the casing coupled with the projection window protecting rim, and hook holes caught by the plurality of catch hooks are formed to the other end of the casing.

15. The bar code reader of claim 1, further comprising a battery cover that can be dissembled and assembled for inhibiting separation of a battery disposed within the casing.
