1 is a perspective view of a mobile terminal according to an embodiment of the present invention. 2 is an exploded perspective view showing an example in which a barcode scan module is mounted on a printed circuit board in a case in FIG.

1 and 2, a mobile terminal 100 according to an exemplary embodiment of the present invention includes a printed circuit board 110, a barcode scan module 120, and a case 130.

The printed circuit board 110 has a shape in which two surfaces having a relatively large area are formed in parallel and have a thickness. The printed circuit board 110 has a relatively narrow surface area.

The barcode scan module 120 scans the one-dimensional barcode 10 (see FIG. 3). The one-dimensional bar code 10 is a code in the form of stripes in which black and white lines are different in thickness according to the article information. The one-dimensional bar code 10 may be printed or attached to the article. The bar code scan module 120 is mounted on one end of the printed circuit board 110 with the scanning direction aligned with the thickness direction of the printed circuit board 110.

The case 130 receives the barcode scan module 120 and the printed circuit board 110 while exposing the scan area 12 of the barcode scan module 120 to the outside. The case 130 has a convex portion corresponding to the barcode scan module 120 and a relatively large portion corresponding to the wide sides of the printed circuit board 110 and a portion corresponding to the narrow sides of the printed circuit board 110 The region may be formed in a narrow shape. Accordingly, the case 130 can accommodate the barcode scan module 120 and the printed circuit board 110 in a compact structure

An example of the operation of the mobile terminal 100 will be described with reference to FIG.

The user generally grasps the case 130 and scans the one-dimensional bar code 10 while the one-dimensional bar code 10 is positioned to scan in the horizontal direction. In this case, the user holds the case 130 so that the scanning direction of the barcode scanning module 120 is positioned in the horizontal direction, directs the scanning portion 121 of the barcode scanning module 120 to the one-dimensional barcode 10 , The one-dimensional bar code 10 is scanned. At this time, the user grasps the case 130 with the large faces of the case 130 facing left and right.

This is because when the user scans the one-dimensional bar code 10, the wrist muscles gripped by the case 130 are more comfortable than when the user holds the case 130 in a state in which the large faces of the case 130 face upward and downward. Therefore, the user can scan the one-dimensional bar code 10 in a comfortable posture without giving a strain to the muscles of the wrist.

Meanwhile, a cutout groove 111 may be formed at one end of the printed circuit board 110. The bar code scan module 120 can be inserted into the incision groove 111 with the scanning direction aligned with the thickness direction of the printed circuit board 110. The central portion of the bar code scan module 120 is fixedly inserted into the cutout groove 111 and can be connected to the printed circuit board 110. Although not shown, a conductive pattern is formed on the printed circuit board 110, and an electric element, an electronic element, or the like for driving the mobile terminal 100 may be connected through a conductive pattern.

As shown in FIG. 4, the mobile terminal 100 may include a trigger button 140 for operating the barcode scan module 120. The trigger button 140 may be disposed on one side of the case 130 with the barcode scan module 120 being positioned in the longitudinal direction. The trigger button 140 may be mounted on the printed circuit board 110 and exposed to the outside of the case 110. When a trigger signal is generated by the user pressing the trigger button 140, a trigger signal may be input to the barcode scan module 120 to operate the barcode scan module 120.

The case 130 may have a grip groove 131 formed on at least one side surface of both sides of the case 130 as a reference when the scanning direction of the barcode scanning module 120 is positioned in the longitudinal direction. The grip groove 131 may be formed in such a manner that a user's finger is inserted. The grip groove 131 may be formed on the opposite side surface of the case 130 on the side where the trigger button 140 is not disposed. Of course, the grip grooves 131 may be formed on both side surfaces of the case 130, respectively.

The case 130 may include a first case 132 and a second case 133 that can be assembled or disassembled with each other. The display module 101 and the keypad 102 may be mounted on the first case 132. [ The display module 101 may be disposed closer to the scan area 121 of the barcode scan module 120 than the keypad 102. [ The second case 133 may be provided with a battery accommodating part for accommodating the battery and a battery cover for opening and closing the battery accommodating part.

5, when the user grasps the bar code scan module 120 in a state in which the case 130 is standing up with the scanning direction of the bar code scan module 120 being positioned in the horizontal direction, the trigger button 140 Can be moved upward and disposed. Accordingly, the user can operate the barcode scan module 120 by pressing the trigger button 140 with a thumb or the like while holding the case 130. At this time, the user can hold the case 130 in a stable and comfortable state by inserting another finger into the grip groove 131. After the scan operation of the barcode 10 is completed by the barcode scan module 120, the mobile terminal 100 displays an alarm unit for visually informing the user if the scan is successful, a lamp for visually informing the user . The lamp may be disposed on the side surface of the case 130 in which the trigger button 140 is disposed.

The barcode scan module 120 may be a laser type one-dimensional barcode scan module. Referring to FIG. 6, the barcode scan module 120 includes an optical unit 122 and a control unit 123. The optical section 122 includes a laser diode 1221, a collimator lens 1222, a folding mirror 1223, a scan mirror 1224, an actuator 1225, a condenser mirror 1226, And may include a photodiode 1227.

The laser diode 1221 emits a laser. The collimator lens 1222 condenses the laser signal. The folding mirror 1223 sends the laser beam passed through the collimating lens 1222 to the scan mirror 1224. [ The scan mirror 1224 irradiates the bar code 10 with the laser reflected from the folding mirror 1223. [ The actuator 1225 moves the laser to vibrate the scan mirror 1224 to scan the barcode 10 one-dimensionally. The condensing mirror 1226 condenses the laser beam to transmit the light reflected from the bar code 10 to the photodiode 1227. The photodiode 1227 converts the laser from the condensing mirror 1224 into an electrical signal. The analog signal output from the photodiode 1227 is converted into a digital signal and transmitted to a decoder, and information of the bar code 10 is decoded by a decoder.

The control unit 123 may include a control unit for controlling the actuator 1225 to vibrate the scan mirror 1224, a laser control unit for controlling the amount of laser, and a signal conversion unit for converting the analog signal into a digital signal . The control unit 123 may be connected to the main control unit of the printed circuit board 110 that controls the entirety of the mobile terminal 100 or may be integrated into the main control unit.
