Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product data input device for reading barcodes attached to products using a barcode scanner or inputting product data using a keyboard.

Conventional technology In the past, a barcode scanner and a keyboard were placed in the center of a soccer table, and baskets were placed at both ends of the soccer table, and during the process of transferring products taken from one basket to the other basket, the barcode scanner and keyboard were placed in the center of the soccer table. If there is no barcode attached, or if the barcode is soiled or damaged and cannot be read by the barcode scanner, the product category There is a product data input device in which price registration is performed using a keyboard, and the registration result is displayed on a display for confirmation by an operator. A product data human horn device is being considered that is equipped with a keyboard and a display.

Problems to be Solved by the Invention Since the barcode scanner is fixedly held, the scanning direction and scanning range of the laser beam from its reading window are constant. On the other hand, the position of the barcode differs depending on the product, and the height of the product held differs depending on the height of the operator. As a result, when the product data is read by a barcode scanner, the operator visually confirms the position of the barcode, faces the reading window, and then looks at the display to confirm the reading result. Because it is arranged at a higher position, when the barcode of a product is placed opposite the reading window of the barcode scanner, the display is out of the field of view. After viewing the screen, the user must change his or her line of sight to look at the display, which poses a problem in that the eyes become easily fatigued.

Means for Solving the Problems Claim 1 provides a barcode scanner that includes a keyboard for inputting product data supported by a support part and has a reading window on the front, and a barcode scanner that is connected to the barcode scanner and the keyboard. A display for an operator was arranged below the keyboard and mounted on the support.

According to a second aspect of the present invention, a barcode scanner is attached to the support portion so as to be rotatable in a downward direction from a substantially vertical position, and a display device is disposed below the barcode scanner.

In claim 3, the display device is rotatably attached to the support portion with a horizontal rotation axis.

In a fourth aspect of the present invention, the keyboard is attached to the support part so as to be able to rise and fall freely.

According to the first aspect of the invention, when the barcode of a product is faced to the reading window of the barcode scanner, the display device can be positioned within the field of view when both are viewed, thereby allowing the line of sight to move over a wide range. You can check the displayed results on the display without having to worry about it.

According to claim 2, since the barcode scanner can be rotated downward according to the height of the operator, it is possible to face the reading window of the barcode scanner without lifting the product by unnaturally bending the arm. In this case, it becomes possible to see the display status of the display device within the field of view of the product located below the reading window.

According to the third aspect of the present invention, the display can be turned toward the operator in accordance with the operator's height to make the display state easier to see.

According to claim 4, the elevation angle of the keyboard can be adjusted according to the height of the operator, thereby improving the operability of the keyboard.

Example An embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, a frame 2 provided in the center of a soccer table 1 includes a barcode scanner 4 having a reading window 3 on the front, a keyboard 6 for inputting product data, and a display 7 for an operator. is installed. Further, a card insertion portion 5a into which a magnetic card is inserted is integrally formed in the main body case 5 of the keyboard 6.
A magnetic data reading section (not shown) for reading the magnetic data of the magnetic card is built in the lower part of the magnetic card.

As shown in FIG. 8, the frame 2 has a pair of left and right columns 8, a column cover 9 that covers the outside of these columns 8 from the center to the top, and a U-shaped frame 10.
The support column 8 and the frame body 1o are connected by a mounting screw 11 so that the height can be adjusted freely.

That is, a mounting screw 11 that is screwed into a screw hole formed on the inner side surface of the frame body 10 is inserted into the column 8, and a cell vertically elongated hole 12 and a plurality of mounting holes 13 are arranged in the vertical direction. There is. Therefore, by selecting the mounting hole 13 through which the mounting screw 11 passes, the overall height of the frame 2 is adjusted. Further, vertically long protrusions 14 are fixed to the circular outer surface of the frame 10, and a guide member 16 that guides the rectangular tube 15 fixed to these protrusions 14 in a vertically movable manner stands fixedly from the floor. It is set up. A longitudinal groove 17 is formed on the inner surface of these guide members 16 to allow the protrusion 14 to escape. The lower part of the frame 2 is fixed to a piston 19 of a hydraulic cylinder 18 fixed to the floor, and this hydraulic cylinder 18 and a hydraulic jack 20 are connected by a pipe 21. The hydraulic jack 20 has an operation pedal 20a located on the right side of the barcode scanner 4 and below the soccer table 1 (see FIG. 1).

Next, a support structure for the barcode scanner 4 and the keyboard 6 will be explained with reference to FIGS. 2 and 3. FIG. 2 is a left side view of the frame 2 with one support 8 removed, and FIG. 3 is a vertical left side view. Retained. That is, the frame 2 has a function as a support portion that rotatably supports the keyboard scanner 4.

The housing 23 of the barcode scanner 4 has a mounting base 24 made of metal E fixed to its upper surface and opened upward in a U-shape. A base of a stop lever 26 having pins 25 protruding outward from the free rotation end is held rotatably around a support shaft 27, and these pins 25 are guided along the rotation direction of the barcode scanner 4. Guide members 28 are fixed to the inner surface of the support column 8, and a plurality of locking holes 29 that engage with the pins 25 are arranged along the longitudinal direction of the guide members 28. In addition, since the stop lever 26 is formed of an elastic material, it can be elastically bent in the thickness direction.

The keyboard 6 has a metal base 3° on the lower surface,
The base 3o is open downward in a U-shape, and both sides of the base 3o and both sides of the mounting base 24 are connected by a support shaft 31 so as to be vertically movable. These support shafts 31 are located on the front side (on the right side in FIGS. 2 and 3) when viewed from the operator side. That is, the mounting base 24 has the function of a support section that supports the keyboard 6. Of course, the keyboard 6 may be rotatably attached to the frame 2. Further, on both sides of the base 30, a plurality of locking portions 32 are arranged in a sawtooth shape on a radius centered on the support shaft 31, and a shaft-shaped locking body that engages with any of these locking portions 32 is provided. 33
are held in elongated holes 34a formed on both sides of the mounting base 24. These elongated holes 34a are in the direction in which the locking body 33 moves forward and backward relative to the locking portion 32, as shown in FIGS. 3 and 5. The locking body 33 is biased by a spring 34 whose one end is fixed to the circular outer surface of the mounting base 24, and is thereby elastically engaged with one of the locking portions 32.

Next, based on FIGS. 2 to 4, the structure of the operating mechanism for retracting the locking body 33 from the locking portion 32 and the operation mechanism for retracting the pin 25 of the stop lever 26 from the locking hole 29 will be explained. explain. First, FIG. 4 is a cutaway plan view of the upper surface of the base 30 of the keyboard 6. In the figure, 35 is an operating mechanism for retracting the locking body 33 from the locking portion 32, and 36 is a stop lever from the locking hole 29. This is an operation mechanism for retracting the pins 25 of 26. One operating mechanism 35 has a grip portion 37 that protrudes toward the front side when viewed from the operator, and is attached to the mounting base 3.
4, a lever 39 rotatably held by a support shaft 38, and a wire having one end fixed to a position away from the support shaft 38 and the other end fixed to the shaft-shaped locking body 33. 40 and more.

The paths of these wires 40 are determined by pulleys 41, 42.degree. 43 rotatably attached to the bottom surface and the circular outer surface of the mount 24. Further, the lever 39 is biased clockwise by the tension of the wire 40 based on the tension of the spring 34, but the lever 39 is rotated clockwise by a stopper pin 44 erected on the bottom surface of the mounting base 24. The scope is regulated. The other operating mechanism 36 has a grip portion 45 that protrudes toward the front side when viewed from the operator, and is attached to the mounting base 24.
A lever 4 rotatably held by a support shaft 46 on the bottom of the
7, and sliding rods 48 and 49 each having one end rotatably held at a position away from the support shaft 46 and the other end connected to the stop lever 26. A stopper pin 50 that restricts the clockwise rotation range of the lever 47 and a guide pin 51 that guides the movement of the sliding rods 48, 49 (7) are erected on the bottom surface of the mounting base 24. In addition, the sliding rod 48,
49 protrudes from the outer side of the mounting base 24, and bent pieces 52 along the stop lever 26 are formed at the protruding end, and these bent pieces 52 have a vertical direction as shown in FIGS. A long slot 53 is formed in the hole 53 . A screw tube 54 erected in the middle part of the stop lever 26 is inserted into these long holes 53, and as shown in FIG.
By screwing the screw 55 into the threaded tube 54 from the inside, the bending part 52 of the sliding rod 48, 49 and the stop lever 26
are connected. A compression spring 56 fitted to the screw rod 54 is interposed between the bending piece 52 and the stop arm 26.

As mentioned above, the rotation range of the lever 39 is determined by the stopper pin 44, but the wire 4 is rotated counterclockwise to the limit of the rotation range.
The rotation range of the lever 39 is determined so that even if the lever 39 is pulled, the locking body 33 is slightly caught in the opening of the locking portion 32. In case 2, an allowance is expected in the length of the elongated hole 34a so that the locking body 33 can be further separated from the locking portion 32.

Next, a support structure for supporting the display device 7 to the support column 8 is shown in FIG. FIG. 7 is a longitudinal sectional side view of the lower part of the frame 2, and the outer casing 57 of the display 7 is formed by joining a case 58 and a translucent cover 59 with their opening surfaces aligned. This outer casing 57 is penetrated by an irregularly shaped shaft 6o that is fixedly installed on the pillars 8 on both sides, and this irregularly shaped shaft 60
A plate-shaped cam 6 has a plurality of locking portions 61 formed in a sawtooth shape along the radial direction centering on the irregularly shaped shaft 60 at both ends of the cam 6.
A locking piece 63 that elastically engages with one of these locking portions 61 is fixed to a boss 64 erected on the case 58 with a screw. A slit-shaped fitting portion 65 that fits into the cam 62 is formed on both sides of the case 58. The inner walls at both ends of these fitting portions 65 are brought into contact with both surfaces of the cam 62, and thereby the outer casing 5
7's axial movement with respect to the irregularly shaped shaft 60 is restricted. Further, the side edge of the cam 62 in the direction around the axis of the irregularly shaped shaft 60 faces the inner wall of the fitting part 65 with a predetermined play,
Thereby, the rotation range of the outer casing 57 with respect to the irregularly shaped shaft 60 is set to approximately 15 degrees.

Further, the bottom surface of the case 58 is open for inserting the irregularly shaped shaft 60 and the cam 62, and a bottom cover 66 is fixed to this bottom surface with screws. Therefore, the frame 2 also has a function as a support section that supports the display device 7. Such a display 7 is for the operator, and as shown in FIGS. 2 and 3, a display 67 for the customer is used.
are installed at both ends of the upper part of the support column 8.

In such a configuration, the locking body 33 is connected to the spring 34.
By engaging with any of the locking portions 32 of the base 30 of the keyboard 6, the rotational movement of the keyboard 6 about the support shaft 31 is prevented, and the keyboard 6 is maintained in a stable state at a predetermined position. be done. Then, hold the grip part 37 that protrudes from the lower front edge of the keyboard 6 toward the operator side, and use the lever 3.
By rotating 9 counterclockwise, the wire 40 is pulled, and the locking body 33 retreats from the locking portion 32 against the biasing force of the spring 34. Thereby, the keyboard 6 can be tilted at any angle about the support shaft 31. In this work of adjusting the tilt angle of the keyboard 6, the lever 39
By restricting the rotation range of the locking member 33 with the stopper pin 44, the locking body 33 can be maintained in a state slightly engaged with the locking portion 32, as shown in FIG.
The keyboard 6 does not fall down carelessly due to its own weight. In this state, by rotating the base 30 together with the keyboard 6, the locking body 33 is retracted in a direction away from the locking part 32 by a component force based on the rotational force acting on the keyboard 6, and the base 30 is rotated. Allow movement. Also,
As shown in FIG. 5, a stopper 30a located above the uppermost locking part 32 and a stopper 30b located below the lowermost locking part 32 are formed on both sides of the base 30. By supporting the locking body 33 with the stoppers 30a and 31b, the range of rotation of the keyboard 6 relative to the mounting base 24 is restricted.

Also, the bins 2 of the stop levers 26 on both sides of the mounting base 24
5 is engaged with one of the locking holes 29 of the guide member 28, the barcode scanner 4 is prevented from rotating around the support shaft 22, and is stabilized at a predetermined position. However, by gripping the grip portion 45 and rotating the lever 47 counterclockwise, the sliding rods 48 and 49 are pulled inward, and the sliding rods 48 and 49 move the stop lever 26 inward. Pull to. As a result, the stop lever 26 is bent inward and the bottle 25 is removed from the locking hole 29. Thereby, the barcode scanner 4 can be tilted about the support shaft 31 from a vertical state parallel to the support column 8 to a downward state. When the lever 47 is released, the stop lever 26 returns to the outside while pulling the sliding rods 48 and 49 by its own elasticity, and the bottle 25 is engaged with one of the locking holes 29 of the guide member 28.

Further, since the tip of the locking piece 63 elastically engages with the locking portion 61 of the cam 62, the display 7 is maintained in a stable state at a predetermined -1- direction angle. The angle of elevation is adjusted by rotating the outer casing 57 around the irregularly shaped shaft 60 fixed thereto.

At this time, the locking piece 63 changes the locking part 61 to be engaged.

Further, when the operating pedal 20a of the hydraulic jack 2o is stepped on gradually, hydraulic pressure is supplied to the hydraulic cylinder 18, so the piston 19 pushes up the frame 2, and the frame 2 becomes stable at the position where the foot is removed from the pedal 20a. Further, when the pedal 20a is pressed all the way, the oil pressure of the hydraulic cylinder 18 is returned to the hydraulic jack 20, so that the frame 2 is lowered.

Thereby, the heights of the barcode scanner 4, keyboard 6, and displays 7, 67 can be adjusted freely. Furthermore, by using the hydraulic jack 20 as a power source for raising and lowering, the height can be easily adjusted according to the operator's height with little effort. Furthermore, since the operation pedal 20a is located on the right side of the barcode scanner 4 and below the soccer table 1, when standing in front of the barcode scanner 4 and reading product data, there is no effect inside the shell. Operate the pedal 20a with your right foot
The height of the frame 2 can be adjusted in its natural posture by stepping on the hydraulic jack 20.

When registering product data, the operator reads the barcode attached to the product using the barcode scanner 4 while taking the product out of the basket placed at one end of the soccer table 1 and transferring it to the basket placed at the other end. If a barcode is not attached or if the barcode is soiled, the user inputs product data using the keyboard 6 while alternately looking at the display screen showing the quality of the product and the keyboard 6.

In this case, the operator will look at the product and the keyboard 6 alternately, but as mentioned above, the inclination angle of the keyboard 6 can be adjusted according to the operator's height and posture.
The keyboard 6 can be seen in the line of sight when viewing the product, and if the keyboard 6 is located high for the operator, the surface of the keyboard 6 can be raised, allowing the operator to easily operate the keyboard 6 with his or her wrists bent naturally. can. In this case, since the keyboard 6 rotates using its front edge as a rotational fulcrum, the key arrangement surface approaches the operator side, making it easier to reach. On the other hand, if the keyboard 6 is low for the operator, by reducing the elevation angle of the keyboard 6, the operator can easily operate the keyboard 6 in a naturally bent position. In this case, the inclination angle adjustment work of the keyboard 6 is extremely easily performed by grasping the grip portion 37 protruding toward the operator and rotating the lever 39 to rotate the keyboard 6. Furthermore, since the keyboard 6 can be adjusted not only in its inclination angle but also in height, the keyboard 6 becomes easier to see and the operability is further improved.

Furthermore, the height of the barcode scanner 4 can be adjusted by the hydraulic jack 2o according to the operator's height, and the inclination angle of the barcode scanner 4 can also be adjusted. Therefore, the barcode of the product can be opposed to the reading window 3 without unnaturally bending the arm and lifting the product close to the reading window 3 of the barcode scanner 4. Furthermore, if the reading window 3 is facing downward, the upper part of the barcode scanner 4 approaches the operator side, and scanning is easier if the operator moves away from the soccer table 1. As the keyboard 6 moves toward the operator side with the rotational movement, the keyboard 6 is also easily accessible. in this case,
The orientation of the keyboard 6 changes as the barcode scanner 4 rotates, but if it is difficult to operate in that orientation, the inclination angle of the keyboard 6 may be readjusted by the operation described above.

Furthermore, by arranging the display device 7 below the barcode scanner 4, when looking at both sides to face the barcode of the product to the reading window 3 of the barcode scanner 4, the display device 7 can be seen in the field of view. This makes it possible to check the display results on the display 7 without having to move the line of sight over a wide range. Note that the display 7 does not need to be located below the barcode scanner 4, but may be placed within the field of view of the reading window 3 by placing it below the keyboard 6. Furthermore, the display section of the operator display 7 can be directed toward the operator in accordance with the operator's height to make the display state easier to see.

The other customer display 67 displays the result of input from the barcode scanner 4 or the keyboard 6, but even if the barcode scanner 4 is rotated, the customer display 67 is always oriented in the same direction. can be maintained in a stable condition.

Effects of the Invention Since the present invention is configured as described above, according to claim 1,
When you look at both sides to face the product's barcode to the reading window of the barcode scanner, you can position the display within your field of view. This allows you to see the results displayed on the display without having to move your line of sight over a wide range. In addition, according to claim 2, the barcode scanner can rotate downward according to the operator's height, so the barcode of the product can be checked without having to unnaturally bend the arm to lift the product. can be opposed to the reading window of the barcode scanner, and in this case, the display state of the display can be seen in the field of view of the product located below the reading window. It is possible to make the display state easier to see by turning the display toward the operator according to the height, thereby reducing the range in which the operator moves his/her line of sight, and reducing eye fatigue. As a result, the elevation angle of the keyboard can be adjusted according to the operator's height, and this has the effect of freely selecting how to bend the wrists and improving the operability of the keyboard.
