Read the bar code with or input from the operation unit 4. The input contents are displayed on the operator display unit 5 and the customer display unit 6.

FIG. 5 is a cross-sectional view of the POS terminal 1 of FIG. 4, showing the tilt mechanism of the operator display unit 5 in more detail. The operator display unit 5 includes a tilt base 7
And are rotatably connected at a fulcrum 8. Further, since the tilt guide pin 9 is fitted in the guide hole 7a of the tilt base 7, when the operator display unit 5 is tilted in the direction of the arrow A3 about the fulcrum 8, the operator display unit 5 is rubbed by friction. Can bear the weight of.

In Japanese Utility Model Publication No. 63-31082, a display is rotatably mounted on a case body of an electronic register.
Further, there is described a display mounting structure for an electronic register that allows the display to be easily viewed without any restriction on the installation location of the electronic register by mounting the display in a vertically movable manner.

Further, Japanese Utility Model Laid-Open No. 2-36873 discloses that
A first locking member is provided in the housing, a second locking member is provided in the rotating body provided with the display means, the second locking member is engaged with the first locking member, and the rotating body is moved to a desired position. There is described a mounting structure of a display device such as a cash register, by which the display content of the display means can be surely visually confirmed by rotating and locking.

FIG. 6 is an explanatory view of the viewing angle of the liquid crystal display unit 5'used in the operator display section 5, which is the liquid crystal display unit 5 '.
It shows an optimum angle range in the X direction when a certain point P6 on ′ is viewed. The optimum viewing angle range when the certain point P6 is viewed from the direction l1 perpendicular to the liquid crystal display unit 5'is a range of l3 to l4 in the X direction. The optimum viewing angle range is similarly set for the Y direction.

FIG. 7 is a diagram for explaining the difference in the appearance of the operator display unit 5 depending on the standing position of the operator. In this figure, it is assumed that the viewing angle in the tilt direction is optimally adjusted, and a point on l10 of the operator display unit 5 is viewed. The optimum viewing angle of P5 is 120 to 121, P4
The optimum viewing angle is set to 130 to 131. When viewed from P2, all the points on l10 can be seen well, but when viewed from P1, they fall outside the optimum viewing angle range, so the screen display is not well seen.

In order to solve the above points, a mechanism for swiveling the operator display unit 5 is required.

FIG. 8 shows a problem in the case of swiveling. When the operator display unit 5 is swiveled around a certain point P3, an empty area of the circle 15 is required as a rotation range. In FIG. 8, since the operation unit 4 is placed in this area, the operation unit 4 has to be moved to the front of the device, which causes a new problem that the outer shape of the device is changed.

Therefore, in order to improve the visibility of the display on the display unit depending on the position of the operator's (viewer's) eye, the present invention does not change the external shape of the device such as the POS terminal.
It is intended to provide a mechanism for adjusting the angle and position of the display unit.

[0011]

The present invention employs the following means to solve the above-mentioned problems.

(1) A housing, a swivel guide plate fixed to the housing and having a U-shaped guide hole, a swivel bracket having two guide pins that engage with the U-shaped guide hole, and the swivel. Tilt bracket attached to the bracket so that it can be tilted,
An angle and position adjusting mechanism of a display unit, which is composed of a display unit fixed to the tilt bracket.

(2) The tilt bracket is attached to the swivel bracket by engaging the two protrusions provided on the pair of bushes with the holes and the long holes provided on both sides of the tilt bracket, respectively. The angle and position adjusting mechanism of the display unit according to (1) above.

(3) The angle and position adjusting mechanism of the display section according to (1), in which retaining washers are attached to the two guide pins of the swivel bracket with screws.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
This will be described with reference to FIG.

The liquid crystal display unit 5'and the tilt bracket 12 are fixed to the display base 13 with screws, and the rising portion of the swivel bracket 18 is inserted inside the bent portion of the tilt bracket 12 to make the bush 1
The tilt bracket 12 is fastened with screws by means of 4 and swivel bracket 18. Here, the protrusion 14a of the bush 14 is inserted into the hole 12a and the elongated hole 12b of the tilt bracket 12, and the height of the protrusion 14a is slightly thicker than the thickness of the tilt bracket 12 to be sandwiched. The swivel bracket 18 is not completely fixed. Further, since the tilt bracket 12 is provided with the elongated hole 12b, the operator display unit 5 has the elongated hole 12b centered on the hole 12a.
It can be tilted within the range.

Further, the swivel bracket 18 has two guide pins 18a and 18b standing downward and inserted into the U-shaped guide holes 10a of the swivel guide plate 10, and the retaining washers 11 are screwed. Since it is attached with, U-shaped guide hole 1 without coming off
It can move along 0a and realize a swivel function. The swivel guide plate 10 is fixed to the housing 2 with screws.

Next, the swivel operation will be described with reference to FIG. In FIG. 3, in order to explain the movement of the swivel bracket 18 with respect to the swivel guide plate 10, other structural parts are omitted. FIG. 3A shows the basic position and shows the guide pin 18 of the swivel bracket 18.
a and 18b are at the front corners of the U-shaped guide hole 10a. FIG. 3B is a view in which the operator display unit 5, that is, the swivel bracket 18 is slightly swiveled to the left, and the guide pin 18a has the U-shaped guide hole 10a in the A4 size.
Direction, the guide pin 18b moves in the A5 direction.

FIG. 3C shows a state in which the image is swiveled to the left all the way. The above operation is the same for the swivel in the right direction, and l51, l52, l53, l54
It is possible to swivel without protruding from the area surrounded by. Therefore, the swivel function of the operator display unit 5 can be realized without changing the outer shape of the device. FIG. 1 shows an embodiment in which the mechanism of the present invention is mounted. However, it is possible to realize substantially the same external dimensions as the conventional device of FIG.

[0020]

As is apparent from the above description, according to the present invention, since the display unit can be tilted and swiveled, the operator can adjust the display unit to an angle and a position that are easy to see, which is convenient. The property is improved.

Further, according to the present invention, since the display unit has a mechanism for tilting and swiveling, there is no problem that the external shape of the device such as the POS terminal becomes large.
