Abstract

PURPOSE:To easily and surely position an optical reader main body by forming a part under the blank of an optical reader main body case with a transparent body and providing barometers on the surface and back of the transparent body. CONSTITUTION:A part under the blank of the optical reader main body case is formed with the transparent body 9 and also, the barometers 10, 11 are formed on the surface and the back of the transparent body 9 which enables a reading plane 3 to be visualized from the outside of an optical reader via the transparent body 9. In such a case, since a part under the blank of the optical reader main body case is formed with the transparent body 9, the reading plane 3 can be observed from the outside by an operator via the transparent body 9 and the reading plane 3 can be observed via the transparent body 9 with a character and an image, etc., on a sheet. Since the barometers 10, 11 are formed on the surface and the back of the transparent body 9, the positioning of the optical reader can be easily and surely performed by setting the positions of the barometers 10, 11 appropriately.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable optical reader capable of reading characters, images, etc. on paper by tracing with a hand.

[0002]

2. Description of the Related Art In a conventional portable optical reading device, a reading surface of an optical reading unit is arranged at an end surface thereof, and the reading surface is traced along an object to be read such as characters and images on paper. It is designed to be read optically.

[0003]

However, in the above-mentioned device, there is a possibility that correct reading cannot be performed because it is necessary to perform delicate positioning by the operator's intuition when the reading surface is applied to the sheet.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable optical reading device which can be easily and reliably positioned without any inconvenience conventionally required for character or image input.

[0005]

SUMMARY OF THE INVENTION The present invention provides a portable optical reading device in which a reading surface of an optical reading unit is located at an end face and a character, an image or the like is read by tracing the reading surface along an object to be read. The lower part of the side surface of the optical reading device body case is formed of a transparent body, and the indicators are formed on the front and back surfaces of the transparent body so that the reading surface can be visually recognized from outside the optical reading device body through the transparent body. It is characterized by having done.

[0006]

Since the lower part of the side surface of the optical reading device body case is formed of a transparent body, the operator can see the reading surface of the optical reading unit from the outside through the transparent body.

That is, the reading surface can be seen through the transparent body together with the characters and images on the paper. At this time, since indexes are formed on the front surface and the back surface of the transparent body, by setting the position of the indexes to an appropriate position, the reading device can be positioned easily and surely.

1 is an external view of a portable optical reading device according to an embodiment of the present invention. A reading surface 3 of the optical reading unit is located on one end surface (bottom surface) 2 of the reading apparatus body 1, and a roller 4 is further arranged. A CCD 5 of the optical reading unit is arranged above the reading surface 3, and a lens (not shown) is arranged below the CCD 5. A reading button 6 is provided substantially in the center of the reading device body 1, and an operator traces the reading device body 1 along the paper while pressing the reading button 6 to read characters, images, etc. on the paper with the CCD 5. be able to. A transparent body 9 is formed on a part of the lower side of the case of the optical reading device body 1. In addition, indexes 10 and 11 are formed on the front surface and the back surface of the transparent body 9, respectively.
The roller 4 is connected to an encoder provided inside, and the amount of movement of the reading device body 1 is detected by rotating the roller 4 when tracing the reading device body 1.

FIG. 2 shows a state in which the operator holds the reading apparatus main body 1 with his / her hand 7 and traces in the direction of the arrow while pushing the reading button 6 with the thumb. 8 is a sheet.

FIG. 3 is a schematic sectional view of the optical reading apparatus of this embodiment.

As shown in the drawing, an index 10 of a transparent body 9 formed in a part of the lower side of the case of the reading device main body 1,
11 is set such that the reading center position P is on the extension line connecting them. In addition, 12 is an LED which is a light emitting element, and 13 is a lens.

With this structure, the transparent body 9 is applied from the outside.
As shown in the figure, the reading surface 3 can be seen through, and in that case, the reading center position P point can be known, so that this P point and the center position of the characters, images, etc. on the paper are aligned. The alignment can be done easily.

[0013]

EFFECT OF THE INVENTION By forming a part of the lower side surface of the main body case of the optical reading device with a transparent body and forming an index on the front and back surfaces of the transparent body, the operator reads from the outside with reference to the index. Positions can be easily aligned.
