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, FIG. 7 shows a structure for supporting the display 7 on the column 8. FIG. 7 is a vertical side view of the lower portion of the frame 2. The outer casing 57 of the display 7 is a case 58 and a translucent cover.
It is formed by aligning 59 and the opening surfaces of both. 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. The inner walls of both waterfalls 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 FIGS. 1 to 3, customer indicators 67 are installed at both upper ends of the column 8.

The depth dimension of the upper portion of the frame 2 is set to be larger than the depth dimension of the barcode scanner 4 in the vertical state. That is, as shown in FIG. 1, cover portions 68 are formed on both sides of the upper portion of the frame 2 to cover the side surface of the barcode scanner 4 in a vertical state when viewed from the side surface. Further, the depth dimension on both sides of the intermediate portion of the frame 2 is set to be larger than the length dimension of the diagonal line on the side surface of the display 7 for cashier.
That is, on both sides of the middle portion of the frame 2, cover portions 69 are formed to cover the side surface of the display 7 regardless of the change in the rotational position of the display device 7 when viewed from the side surface.

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, whereby the keyboard 6 with the support shaft 31 as a fulcrum.
The rotational movement of the is blocked and the stable state is maintained at a predetermined position. 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 adjustment work of the keyboard 6, the rotation range of the lever 39 is set to the stopper pin.
As shown in FIG. 5, the locking body is regulated by 44.
It is possible to maintain the state in which 33 is slightly engaged with the locking portion 32, so that the keyboard 6 does not inadvertently descend 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 the direction away from the locking portion 32 by the component force based on the turning force acting on the keyboard 6, and the rotation of the base 30 is performed. Allow movement. Also, as shown in FIG. 5, a stopper 30a located above the uppermost locking portion 32 and a stopper 30b located 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 bar 26 on both sides of the mounting base 24 are engaged with any of the locking holes 29 of the guide member 28, the barcode scanner 4 moves in the rotation direction about the support shaft 22. Although the movement is blocked and the stable state is maintained at a predetermined position, the sliding rods 48, 49 are pulled inward by grasping the grasping portion 45 and rotating the lever 47 counterclockwise, Sliding rod 48,49
Pulls the 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.

Further, in the indicator 7, the tip of the locking piece 63 is the locking portion of the cam 62.
Since it is elastically engaged with 61, it remains stable at a predetermined upward angle, but the elevation angle is adjusted by rotating the outer casing 57 around the deformed shaft 60 fixed together with the cam 62. It 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 stand 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.

Further, during transportation and the like, the barcode scanner 4 is maintained in a vertical state in parallel with the column 8 of the frame 2. In this state, the barcode scanner 4 is covered by the frame 2.
Since it does not protrude from the front and rear edges of 68, it does not interfere with external objects. Further, since the display device does not stick out from the front edge and the back surface of the cover portion 69 of the frame 2 regardless of the change of the rotation position, it does not interfere with external objects.

Next, a second embodiment of the present invention will be described based on FIG. The same parts as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted. In this embodiment, when the barcode scanner 4 is rotated vertically and the keyboard 6 is maintained at the minimum elevation angle, a cover portion 70 that covers both sides of the keyboard 6 when viewed from the side is formed at the upper end of the frame 2. Covers the interference of the barcode scanner 4 and the indicator 7 against external objects during transportation.
In addition to the prevention by the 68 and 69, the cover 70 prevents the keyboard 6 from interfering with external objects.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, in carrying and the like, according to claim 1, the rotation position of the barcode scanner is determined, and the barcode scanner is housed in the cover portion of the frame when viewed from the side. It is possible to prevent the interference between the display and the external object by the frame cover, and in the present invention, the interference between the display and the external object is prevented by the frame cover regardless of the change of the rotation position of the display. Can be prevented, claim 3
Then, there is an effect that interference of the barcode scanner and the display with respect to an external article can be prevented by the cover portion of the frame.
