Abstract

A portable optical reader is provided with: a reading part 41 optically reading a symbol as a reading object; a head part 3 storing the reading part 41 and having a reading port 4 for the reading part 41 ; a holding part 2 continuously connected to the head part 3 and extending in a connecting direction; and a display part 22 provided in the head part 3 and displaying at least a reading result. The head part 3 is formed by side surfaces, and the display part 22 is provided in at least two side surfaces which are a side surface facing to a surface providing the holding part 2 , and a side surface in which a reading direction by the reading part 41 and an extending direction of the holding part 2 are substantially orthogonal to each other.

First claim

What is claimed is:

1. A portable optical reader comprising:
a reading part optically reading a symbol as a reading object;
a head part housing the reading part and having a reading port for the reading part;
a holding part continuously connected to the head part and extending in a connecting direction; and
a display part provided in the head part to display at least a reading result read by the reading part,
wherein the head part has outer side surfaces, and the display part is provided on at least two of outer side surfaces, the outer side surfaces being a side surface facing to a surface on which the holding part is connected, and being a side surface substantially orthogonal to both a reading direction by the reading part and an extending direction of the holding part.

2. The portable optical reader according to claim 1 , wherein the display part has a first display part in one side of a pair of the outer side surfaces facing in a direction substantially orthogonal to the extending direction of the holding part, and has a second display part in another side.

3. The portable optical reader according to claim 1 , wherein on the side surfaces which form the head part, the display part is provided in a position further forward than a rear surface of the holding part.

4. The portable optical reader according to claim 1 , wherein the display part has an inclined surface separating from a reading optical axis of the reading part while being closer to the reading port.

5. The portable optical reader according to claim 1 , wherein the display part extends along a circumference direction of the reading port.

6. The portable optical reader according to claim 5 , wherein the display part includes a plurality of display elements continuously provided in an extending direction of the holding part.

7. The portable optical reader according to claim 1 , wherein the holding part is continuously connected to the head part in a manner in which the extending direction of the holding part is substantially parallel to a plane surface including the reading port of the reading part.

8. The portable optical reader according to claim 1 ,
the portable optical reader further comprising a switch for switching to a tune mode, the tune mode being for optimizing parameters to read a code.

9. The portable optical reader according to claim 8 , wherein the display part indicates completion information when an optimization analysis is completed in the tune mode.

10. The portable optical reader according to claim 9 ,
the reading part comprising a camera configured to capture a plurality of images of a symbol prior to the optimization analysis in the tune mode, and a memory configured to store the plurality of images captured by the camera, wherein
the display part notifies a user of the completion of capturing the plurality of images by the camera.

11. A portable optical reader comprising:
a reading part optically reading a symbol as a reading object;
a dome-shaped member provided in front of the reading part, the dome-shaped member having a first opening, a side wall surface and a second opening, the first opening through which a reading optical axis of the reading part passes formed on a rear end surface of the dome-shaped member which faces to the reading part, the sidewall surface having a diameter which progressively or gradually becomes larger with an increase of a distance from the first opening, and the second opening formed in a front end of the sidewall surface;
the reading part and the dome-shaped member being housed within a head part, the head part having a side surface having a diameter which progressively and gradually becomes larger from a rear side to a front side, and having a reading port in a position facing to the second opening;
a holding part extending in a direction increasing a distance from a reading optical axis of the reading part, one end of the holding part being mounted on the side surface of the head part; and
a display part displaying at least a reading result read by the reading part, the display part provided to the side surface except a portion where the holding part is mounted within the side surface of the head part.

12. The portable optical reader according to claim 11 , wherein the display part is formed in an elongated shape in which a direction along a circumference of the side surface of the head part is defined as a longitudinal direction.

13. The portable optical reader according to claim 11 , wherein the dome-shaped member is a diffusion plate.

14. The portable optical reader according to claim 11 ,
the head part having the reading port at the front side of the head part in a position facing to the second opening of the dome-shaped member.

15. The portable optical reader according to claim 11 ,
the display part including an indicator for notifying a user of a reading result read by the reading part.

16. The portable optical reader according to claim 11 ,
the portable optical reader further comprising a switch for switching to a tune mode, the tune mode being for optimizing parameters to read a code.

17. The portable optical reader according to claim 16 , wherein the display part indicates completion information when an optimization analysis is completed in the tune mode.

18. The portable optical reader according to claim 17 ,
the reading part comprising a camera configured to capture a plurality of images of a symbol prior to the optimization analysis in the tune mode, and a memory configured to store the plurality of images captured by the camera, wherein
the display part notifies a user of the completion of capturing the plurality of images by the camera.

19. A portable optical reader comprising:
a reading part optically reading a symbol as a reading object;
a head part housing the reading part and having a reading port for the reading part;
a holding part continuously connected to the head part and extending in a connecting direction; and
a display part provided in the head part to display at least a reading result read by the reading part,
wherein the head part has outer side surfaces, and the display part is provided on at least two of outer side surfaces, the outer side surfaces being a side surface facing to a surface on which the holding part is connected, and being side surfaces facing in a direction substantially orthogonal to both a reading direction by the reading part and an extending direction of the holding part.
