FIG. 3 is a left side view of the frame 2 with one of the columns 8 removed, and FIG. 3 is a longitudinal left side view of the frame 2. The column 8 has a lower portion of a bar code scanner 4 rotatably supported by a support shaft 22. 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. The housing 23 of the barcode scanner 4 has a metal mounting base 24 fixed to the upper surface thereof and opened upward in a U-shape.
A base of a stopper bar 26 having a pin 25 projecting outward from a free end of rotation is rotatably held around a support shaft 27 on both outer side surfaces of 24, and these pins 25 of the bar code scanner 4 are held. A guide member 28 that guides along the rotation direction is fixed to the inner surface of the column 8, and a plurality of locking holes 29 that engage with the pins 25 are arranged along the longitudinal direction of these guide members 28. There is. 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. 2 and 3) 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. 3 and 5, 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. 4 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 for restricting the turning range of the lever 47 and a guide pin 51 for guiding the movement of the sliding rods 48, 49 are provided upright 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 a bending piece 52 is formed along the stopper bar 26 at the protruding end thereof.
As shown in FIGS. 2 and 3, these bent pieces 52 are formed with elongated holes 53 which are long in the vertical direction. These long holes 53
A screw tube 54 provided upright in the intermediate portion of the stopper lever 26 is inserted into the screw tube 54, and as shown in FIG.
The bent pieces 52 of the sliding rods 48, 49 are connected to the stopper lever 26 by screwing 55 onto the screw tube 54. A screw rod 54 is provided between the bending piece 52 and the stop arm 26.
A compression spring 56 fitted to the above is interposed.

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 support column 8
Shown in the figure. FIG. 7 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 a cashier and the second
As shown in FIG. 3 and FIG. 3, the display devices 67 for customers are installed at both upper ends of the support 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 the work of adjusting the inclination angle of the keyboard 6, by restricting the rotation range of the lever 39 by the stopper pin 44, 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. 5, 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 operation pedal 20a of the hydraulic jack 20 is stepped on and off, hydraulic pressure is supplied to the hydraulic cylinder 18, so that the piston 19 pushes up the frame 2 and the frame 2 is stabilized at a position where the foot is released from the pedal 20a. When the pedal 20a is depressed all the way, the hydraulic pressure in the hydraulic cylinder 18 is changed to the hydraulic jack 20.
Then, 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. Furthermore, by using the hydraulic jack 20 as a power source for lifting and lowering, it is possible to easily perform height adjustment work according to the height of the cashier with a little labor. Further, since the operation pedal 20a is arranged on the right side of the barcode scanner 4 and below the sasker table 1, when the product data is read while standing in front of the barcode scanner 4, it is generally used. The height of the frame 2 can be adjusted in a natural posture by stepping on the operation pedal 20a with the right foot, which is the effective foot, and driving the hydraulic jack 20. Moreover, the reference height of the bar code scanner 4, the keyboard 6 and the display 7 is adjusted without changing the hydraulic cylinder 18 by changing the connecting length between the support column 8 and the frame 10. It is possible to adjust the heights of the barcode scanner 4, the keyboard 6 and the display 7 by moving the frame 2 up and down by the hydraulic cylinder 18 with reference to the height.
Therefore, the stroke of the hydraulic cylinder 18 can be minimized to reduce the capacity of the hydraulic jack 20.

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.

Further, the height of the barcode scanner 4 can be adjusted by the hydraulic jack 20 according to the height of the cashier, and the inclination angle of the barcode scanner 4 can also be adjusted. Therefore, the bar code of the product can be opposed to the reading window 3 without bending the arm unnaturally and lifting the product to the vicinity of the reading window 3 of the bar code scanner 4. Further, if the reading window 3 is directed downward, the upper portion of the barcode scanner 4 approaches the cashier side, and accordingly, it is easier for the cashier to skim away from the sasker base 1, but the barcode scanner 4 has the cashier side. Since the keyboard 6 is moved closer to the cashier side with the turning movement to, 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. Since the vertical position of the frame 2 can be adjusted, even if the barcode scanner with the reading window facing upward is attached to the frame 2, the barcode can be read while holding the product in a natural posture. be able to.

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 the first aspect, by driving the elevating mechanism by the drive source to elevate the frame, the barcode scanner can be adjusted according to the type of product or the height of the cashier. The position of the bar code in the height direction can be adjusted so that the bar code can be positioned within the scanning range of the laser beam while holding the product in a natural posture, and the bar code can be read reliably and easily. Further, according to claim 2, when the product data is read while standing in front of the barcode scanner, the right foot, which is generally effective, drives the drive source to adjust the frame height naturally. It has the effect that it can be adjusted depending on the posture.
