Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product data input device for reading a bar code attached to a product with a bar code scanner or inputting product data with a keyboard.

Conventional technology Conventionally, a barcode scanner and a keyboard are arranged in the center of a Satsuka stand, baskets are placed at both ends of the Satsuka stand, and the products taken out from one basket are transferred to the other basket. Read the attached barcode with a barcode scanner, if the barcode is not attached, or if the barcode cannot be read because it is dirty or damaged, There is a product data input device in which the department and price of a product are registered using a keyboard.

Problems to be Solved by the Invention Since the barcode scanner is fixedly held, the scanning direction and the scanning range of the laser light from its reading window are constant. On the other hand, the position of the bar code differs depending on the product, and the height of the product held by the height of the cashier also differs. As a result, in order to position the barcode within the scanning range of the laser light from the reading window, an unnatural posture such as adjusting the bending amount of the arm or bending the waist is forced, which deteriorates the operability. However, there is a problem that it is easy to get tired.

Means for Solving the Problems In the invention according to claim 1, a keyboard for inputting product data is provided on an upper portion of a barcode scanner having a reading window on a front surface thereof, and the barcode scanner has a horizontal rotation shaft. It was attached to the support part so that it could rotate.

According to a second aspect of the present invention, the front portion of the keyboard is rotatably attached to the upper portion of the barcode scanner with a horizontal rotation axis.

According to the third aspect of the invention, the display unit with the display unit facing the customer is fixed behind the support unit.

According to claim 1, the bar code scanner is rotated according to the type of product or the height of the cashier so that the bar code is positioned within the scanning range of the laser beam while holding the product in a natural posture. Therefore, the barcode reading operation can be performed reliably and easily. Also,
The position where the cashier stands with respect to the sacker stand changes depending on the rotation position of the barcode scanner, but since the keyboard is displaced along with the barcode scanner in the front-back direction, the cache opens an appropriate facing interval for the barcode scanner. In the state of facing each other, the distance to the keyboard is maintained within an appropriate range, and the operability of the keyboard can be satisfied.

Further, according to claim 2, the elevation angle of the keyboard changes depending on the rotation operation of the barcode scanner, but since the rotation angle of the keyboard with respect to the barcode scanner can be adjusted, the keyboard can be adjusted to the optimum elevation angle according to the preference of the operator. Can be set to.

Further, according to claim 3, the input result of the barcode scanner or the keyboard is displayed on the customer display, but even if the barcode scanner is rotated, the orientation of the customer display is always kept in a fixed direction. It can be maintained in the directed state.

Embodiment An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 8, a bar code scanner 4 having a reading window 3 on the front surface and a keyboard 6 for inputting product data are provided on a frame 2 which is a supporting portion provided in the central portion of the sacker stand 1.
And a display 7 for cashier are mounted. Also, a card insertion portion 5a for inserting a magnetic card is integrally formed in the main body case 5 of the keyboard 6, and a magnetic data reading portion (not shown) for reading magnetic data of the magnetic card is provided under the card insertion portion 5a. ) Is built in.

As shown in FIG. 7, the frame 2 includes a pair of left and right struts 8, a stanchion cover 9 that covers the outer sides of these struts 8 from the central part to the upper part, and a U-shaped connection that connects the lower parts of the stanchions 8. It has a frame 10 and is configured to be expandable and contractible.
That is, the column 8 has a vertically elongated slot 12 and a plurality of mounting holes 13 for inserting the mounting screws 11 screwed into the screw holes (not shown) formed on both inner side surfaces of the connecting frame 10 in the vertical direction. Are arranged in. Therefore, the length of the frame 2 is adjusted by selecting the mounting hole 13 through which the mounting screw 11 is inserted. Furthermore, vertically long ridges 14 are fixed to both outer side surfaces of the connecting frame 10,
A guide member 16 that vertically guides a rectangular tube 15 fixed to these ridges 14 is fixedly erected from the floor surface. Longitudinal grooves 17 are formed on the inner surfaces of these guide members 16 so as to allow the protrusions 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 the hydraulic cylinder 18 and the hydraulic jack 20 are connected to a pipe 21.
Connected by.

Next, a support structure for the bar code scanner 4 and the keyboard 6 will be described with reference to FIGS. 1 and 2. First
The figure shows a left side view of the frame 2 with one of the columns 8 removed, and FIG. 2 is a vertical cross-section left side view of which the lower part of the barcode scanner 4 is rotatably held by a support shaft 22 on the column 8. Has been done. The barcode scanner 4 is rotated from the vertical posture parallel to the support column 8 to the right (the cashier side), but the depth dimension of the barcode scanner 4 is set to be narrower than the width of the support column 8. As a result, in the vertical posture, they are located inside the front and rear edges of the column 8. On the upper surface of the housing 23 of the barcode scanner 4, a metal mounting base 24, which is opened in a U-shape upward, is fixed by screws.
A base of a stopper lever 26 having a pin 25 projecting outward from the free rotation end is provided on both outer side surfaces of the mounting base 24 as a spindle.
A guide member 28 that is rotatably held about 27 and that guides these pins 25 along the rotation direction of the barcode scanner 4 is fixed to the inner surface of the column 8 and is attached to these guide members 28. A plurality of locking holes 29 that engage with the pins 25 are arranged along the longitudinal direction thereof. Since the stopper bar 26 is made of an elastic material, it can be elastically bent in the plate thickness direction.

The keyboard 6 has a metal base 30 on the lower surface,
The base 30 is opened downward in a U shape, and both sides thereof and both side surfaces of the mounting base 24 are connected by a support shaft 31 so as to be vertically rotatable. These support shafts 31 are located on the front side (right side in FIGS. 1 and 2) when viewed from the cashier side. Further, on both sides of the base 30, a plurality of locking portions 32 are arranged in a saw-tooth shape on a radius centered on the support shaft 31, and a shaft-shaped locking engagement with any of these locking portions 32 is made. body
33 are held in long holes 34a formed on both sides of the mount 24. As shown in FIGS. 2 and 4, these elongated holes 34a are in the direction in which the locking body 33 is advanced and retracted with respect to the locking portion 32. The locking body 33 is biased by springs 34, one end of which is fixed to both outer side surfaces of the mounting base 24, whereby it is elastically engaged with any one of the locking portions 32.

Next, the structure of the operating mechanism for retracting the locking body 33 from the locking portion 32 and the operating mechanism for retracting the pin 25 of the stopper lever 26 from the locking hole 29 will be described with reference to FIGS. To do. First, FIG. 3 is a plan view in which the upper surface of the base 30 of the keyboard 6 is cut away. In the figure, 35 is an operation mechanism for retracting the locking body 33 from the locking portion 32, 36 is a locking hole 29 and a stopper lever 26. Is an operation mechanism for retracting the pin 25 of. One of the operation mechanisms 35 has a grip portion 37 protruding toward the front side when viewed from the cache, and a lever 39 rotatably held by a support shaft 38 on the bottom surface of the mounting base 24, and separated from the support shaft 38, respectively. The wire 40 has one end fixed to the position and the other end fixed to the shaft-like locking body 33. The paths of these wires 40 are pulleys rotatably mounted on the bottom surface of the mounting base 24 and both outer surfaces.
41, 42, 43. Further, the lever 39 is urged clockwise by the tension of the wire 40 based on the pulling force of the spring 34, but the clockwise rotation range by the stopper pin 44 erected on the bottom surface of the mounting base 24. Is regulated. The other operating mechanism 36 has a lever 47 rotatably held by a support shaft 46 on the bottom surface of the mounting base 24, having a gripping portion 45 projecting to the front side when viewed from the cache,
A slide rod having one end rotatably held at a position separated from the support shaft 46 and the other end connected to the stopper bar 26.
It consists of 48,49. A stopper pin 50 that regulates the clockwise rotation range of the lever 47 and a guide pin 51 that guides the movement of the sliding rods 48, 49 are erected on the bottom surface of the mounting base 24. Further, the sliding rods 48, 49 are projected from both outer sides of the mounting base 24, and the projecting ends thereof are bent pieces along the stop lever 26.
52 are formed, and these bent pieces 52 are formed with elongated holes 53 which are long in the vertical direction as shown in FIGS.
A screw tube 54 provided upright in the middle of the stopper bar 26 is inserted into these elongated holes 53, and as shown in FIG.
The bending piece 52 of the sliding rods 48, 49 and the stop lever 26 are connected by screwing the screw 55 into the screw tube 54 from the inside. A compression spring 56 fitted to the screw rod 54 is interposed between the bending piece 52 and the stop arm 26.

As described above, the rotation range of the lever 39 is determined by the stopper pin 44, but even if the lever 39 is rotated counterclockwise to the limit of the rotation range and the wire 40 is pulled, The rotation range of the lever 39 is set so that the locking body 33 is slightly caught by the opening of the locking portion 32. In this case, there is a margin 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 the display 7 to the column 8 is attached to a sixth structure.
Shown in the figure. FIG. 6 is a vertical cross-sectional side view of the lower portion of the frame 2. 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. A deformed shaft 60 fixedly installed on the columns 8 on both sides is passed through the outer casing 57, and a plurality of locking portions are provided at both ends of the deformed shaft 60 along the radial direction around the deformed shaft 60. A plate-shaped cam 62 having a serrated shape 61 is fixedly fitted, and a locking piece 63 that elastically engages with any one of these locking portions 61 is erected on the case 58. It is fixed to the boss 64 with a screw. Then, on both sides of the case 58, slit-shaped fitting portions 65 that fit into the cam 62 are formed. Inner walls at both ends of these fitting portions 65 are in contact with both surfaces of the cam 62, whereby the axial movement of the outer casing 57 with respect to the deformed shaft 60 is restricted. Further, the side edge of the cam 62 in the direction around the axis of the deformed shaft 60 faces the inner wall of the fitting portion 65 with a predetermined play, whereby the rotation range of the outer casing 57 with respect to the deformed shaft 60 is increased. It is set to about 15 degrees. Further, the bottom surface of the case 58 is open for inserting the deformed shaft 60 and the cam 62, and the bottom cover 66 is fixed to the bottom surface by screws. Such an indicator 7 is for cashier,
As shown in FIG. 2 and FIG. 2, the display 67 for customers is installed on both ends of the upper portion of the column 8.

In such a configuration, the locking body 33 is biased by the spring 34 and engages with any one of the locking portions 32 of the base 30 of the keyboard 6, thereby rotating the keyboard 6 about the support shaft 31 as a fulcrum. Movement is blocked and remains stable in place. Then, the wire 40 is pulled by gripping the grip portion 37 protruding from the lower front edge of the keyboard 6 toward the cashier side and rotating the lever 39 counterclockwise, and the locking body 33 is biased by the spring 34. It retreats from the locking part 32 against.
As a result, the keyboard 6 can be tilted around the support shaft 31 at an arbitrary angle. In this tilt angle adjusting operation of the keyboard 6, the rotation range of the lever 39 is restricted by the stopper pin 44, so that the locking body 33 is slightly engaged with the locking portion 32 as shown in FIG. Therefore, the keyboard 6 is prevented from being inadvertently lowered due to its own weight. In this state, by rotating the base 30 together with the keyboard 6, the locking body 33 is locked by the locking member 33 by the component force based on the turning force acting on the keyboard 6.
It retracts in the direction away from and allows the pivotal movement of the base 30. Further, as shown in FIG. 4, a stopper 30a positioned above the uppermost locking portion 32 and a stopper 30b positioned below the lowermost locking portion 32 are formed on both side surfaces of the base 30. By supporting the locking body 33 with these stoppers 30a and 31b, the range of rotation of the keyboard 6 with respect to the mount 24 is restricted.

Further, since the pins 25 of the stopper levers 26 on both sides of the mounting base 24 are engaged with any of the locking holes 29 of the guide member 28,
The bar code scanner 4 is prevented from moving in the direction of rotation about the support shaft 22 and is maintained in a stable state at a predetermined position, but grips the grip 45 and rotates the lever 47 counterclockwise. By this, the sliding rods 48, 49 are pulled inward, and the sliding rods 48, 49
49 pulls stop lever 26 inward. As a result, the stopper lever 26 is bent inward and the pin 25 is disengaged from the locking hole 29. As a result, the bar code scanner 4 is centered around the support shaft 31.
Can be tilted 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, 49 by its own elasticity, and the pin 25 is engaged with one of the locking holes 29 of the guide member 28.

Furthermore, since the tip of the locking piece 63 is elastically engaged with the locking portion 61 of the cam 62, the indicator 7 is maintained in a stable state at a predetermined upward angle, but is fixed together with the cam 62. The elevation angle is adjusted by rotating the outer casing 57 about the deformed shaft 60. At this time, the locking piece 63 changes the engaging part 61 to be engaged.

Further, when the pedal 20a of the hydraulic jack 20 is adjusted while being depressed, the hydraulic pressure is supplied to the hydraulic cylinder 18, so that the piston
19 pushes up the frame 2 and stabilizes the frame 2 at a position where the foot is released from the pedal 20a. When the pedal 20a is depressed to the end, the hydraulic pressure of the hydraulic cylinder 18 is returned to the hydraulic jack 20 so that the frame 2 descends. As a result, the position heights of the barcode scanner 4, the keyboard 6, and the displays 7, 67 can be freely adjusted. Moreover, by using the hydraulic jack 20 as a power source for raising and lowering, it is possible to easily perform the height adjustment work according to the height of the cashier with a little labor.

When registering the product data, the cashier reads the bar code attached to the product with the bar code scanner 4 in the process of transferring the product taken from the basket placed at one end of the satker table 1 to the basket placed at the other end, If the bar code is not attached or the bar code is soiled, the product data is input by the keyboard 6 while alternately viewing the display surface of the quality of the product and the keyboard 6.
In this case, the product and the keyboard 6 are viewed alternately, but as described above, since the inclination angle of the keyboard 6 can be adjusted according to the height and posture of the cashier,
The keyboard 6 can be seen from the line of sight of the product, and if the keyboard 6 is positioned higher than the other, the keyboard 6 is raised so that the keyboard 6 can be easily operated with the wrist bent naturally. be able to. In this case, since the keyboard 6 rotates with its front edge side as the rotation fulcrum, the array surface of the keys approaches the cashier side, making it easier to reach. On the contrary, when the keyboard 6 is low in the sense of cash, the angle of elevation of the keyboard 6 can be made small so that the user can easily operate in a posture in which the wrist is naturally bent. In this case, the tilt angle adjustment work of the keyboard 6 is extremely easily performed by holding the grip portion 37 protruding toward the cashier side and rotating the lever 39 by rotating the lever 39. Moreover, since the keyboard 6 can be adjusted not only in the inclination angle but also in the height, the keyboard 6 is more easily seen and the operability is further improved.

Furthermore, since the inclination angle of the barcode scanner 4 can be adjusted according to the height of the cashier, it is not necessary to bend the arm unnaturally and lift the product near the reading window 3 of the barcode scanner 4. The barcode of the product can be opposed to the reading window 3. If the reading window 3 is directed downwards, the upper part of the barcode scanner 4 will be closer to the cashier side, and with this, it will be easier for the cashier to skim away from the satker table 1, but the barcode scanner 4 will be closer to the cashier side. Since the keyboard 6 is moved closer to the cashier side with the rotational movement, the keyboard 6 is easily accessible.
In this case, the orientation of the keyboard 6 changes due to the rotation of the barcode scanner 4, but if it is difficult to operate in that orientation, the tilt angle of the keyboard 6 may be readjusted by the above-described operation.

Further, by incorporating the magnetic data reading unit in the main body case 5 of the keyboard 6, it is possible for a customer who uses the magnetic card to settle the price to read the data of the magnetic card in the posture facing the keyboard 6. it can.

Although the input result of the barcode scanner 4 or the keyboard 6 is displayed on the customer display device 67, the orientation of the customer display device 67 is always oriented in a fixed direction even if the barcode scanner 4 is rotated. Can be maintained in a state.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, according to claim 1, the bar code scanner is rotated according to the type of product or the height of the cashier, whereby the product is held in a natural posture. The bar code can be positioned within the scanning range of the laser light by using the bar code, and therefore the bar code can be read reliably and easily. Also, the rotation position of the bar code scanner allows the bar code scanner to move the carriage to the cartridge table. The position of the keyboard changes, but since the keyboard moves in the front-back direction together with the barcode scanner, the distance between the keyboard and the keyboard is kept within the appropriate range when the cache is facing and facing the barcode scanner. As a result, the operability of the keyboard can be satisfied, and further, according to claim 2, the rotational movement of the barcode scanner is performed. The elevation angle of the keyboard changes depending on the work,
Since the rotation angle of the keyboard with respect to the barcode scanner can be adjusted, the keyboard can be set to an optimum elevation angle according to the preference of the cashier. Further, according to claim 3,
The input result of the barcode scanner or keyboard is displayed on the customer display unit, but the orientation of the customer display unit should always be kept in a fixed direction even if the barcode scanner is rotated. It has the effect of being able to.
