Abstract

PURPOSE:To reduce fatigue on an operator by forming a flat read window at the front plane of a case in which an optical system including a light emitting part and a light receiving part is incorporated, forming a spherical surface on a back plane, and supporting the spherical surface of the case in all directions in such a way that it can be turned freely. CONSTITUTION:The optical system including the light emitting part to emit a laser beam and the light receiving part to receive the reflected light of a bar code is incorporated in the case 1. Also, at the front plane of the case 1, the flat read window 2 and an annular projecting part 3 diverging from the edge of the read window 2 are formed, and the spherical surface 4 is formed on the back plane. Also, plural balls 8 that is a receiving part to support the spherical surface 4 in such a way that it can be turned freely in the all directions are held rotatably freely at the inner edge of an aperture 7 formed on a supporting body 5 and the back plane of the supporting body 5. Thereby, it is possible to adjust the direction of the read window 2 upward and downward with an arbitrary angle corresponding to the height of the operator, and also, to adjust the direction of the read window 2 in a a horizontal direction with the arbitrary angle corresponding to the standing position of the operator, which reduces the fatigue on the operator.

Description

[Detailed description of the invention] Industrial applications FIELD OF THE INVENTION The present invention relates to stationary scanners.

Conventional technology In the past, for example, in stores such as supermarkets, barcodes attached to products were transferred from a basket placed at one end of a soccer table to a basket placed at the other end of the soccer table. The product data is read by a code scanner, and if the product does not have a barcode or the barcode cannot be read, the product data is entered using a keyboard.

Problems to be Solved by the Invention Since operators differ in physique and height, the height of a stationary scanner may not suit the operator.

In addition, due to reasons such as changing the layout of the keyboard, or because different people have different keyboard operating habits,
The operator's standing position with respect to the front of the stationary scanner may differ in the left and right directions. However, because conventional stationary scanners cannot adjust their positions in the vertical and horizontal directions, they are forced to take unnatural postures, which causes fatigue after long periods of use. To solve this problem, a stand that changes the orientation of the stationary scanner has been considered, but this poses the problem of complicating the structure.

Means for Solving the Problems A case is provided in which an optical system including a light emitting part and a light receiving part is built in, a flat reading window is formed on the front surface of the case, and a spherical surface is formed on the back surface of the case. A support body having a receiving part for rotatably supporting the spherical surface in all directions was provided.

Since the operation case can be rotated in all directions, the orientation of the reading window can be adjusted to any vertical angle depending on the height of the operator, and the orientation of the reading window can be adjusted to the left or right depending on the operator's standing position. It can be adjusted to any angle.

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

Reference numeral 1 denotes a case, and the case 1 houses an optical system including a light emitting section (not shown) that emits a laser beam and a light receiving section (not shown) that receives reflected light from a bar code.

Further, a flat reading window 2 and an annular protrusion 3 expanding from the periphery of the reading window 2 are formed on the front surface of the case 1.
A spherical surface 4 is formed on the back surface. Reference numeral 5 denotes a box-shaped support body, and this support body 5 is formed with an accommodating portion 6 for accommodating the case 1 and a circular open lower portion slightly larger in diameter than the reading window 2. Therefore, the inner peripheral edge of this opening 17 and the support 5
A plurality of balls 8 are rotatably held on the back surface of the case 1, and are a receiving portion that rotatably supports the spherical surface 4 of the case 1 in all directions. Further, a cable 9 connected to the optical system described above is pulled out from the case 1 with a sufficient length, and a connecting portion 10 is provided for connecting the cable 9 to an external circuit.
is provided on the support body 5.

In such a configuration, the laser beam emitted from the light emitting part inside the case j is irradiated toward the product through the reading window 2, and the reflected light from the bar code of the product is received by the light receiving part inside the case 1. The brightness of the received light beam is converted into an electrical signal and read as a barcode.

On the other hand, since the case 1 can be rotated in all directions, the orientation of the reading window 2 can be adjusted to any vertical angle according to the operator's height, and the reading window 2 can be adjusted according to the operator's standing position. The direction can be adjusted to any angle in the left and right directions. Therefore, operator fatigue can be reduced. In this case, the contact between the inner circumferential surface of the open lower portion of the support 5 and the protrusion 3 of the case 1 prevents excessive rotation of the case 1 and prevents the reading window 2 from being hidden inside the support 5. It can be prevented.

Effects of the Invention Since the present invention is configured as described above, the case can be rotated in all directions, so the orientation of the reading window can be adjusted to any vertical angle according to the height of the operator. The direction of the reading window can be adjusted to any angle in the horizontal direction depending on the position of the camera. Therefore, it is possible to reduce operator fatigue.
