[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information reading device for reading information written on a label such as a bar code.

[0002] In recent years, an increasing number of products are provided with a label in which a bar code is described for classification, selection of products, accounting for purchasing products, and the like. Such a bar code is read by a reading device, and the reading device includes an installation type, a handy type, and a combination thereof. In particular, the dual-purpose one is desired to have improved operability when gripped.

[0003]

2. Description of the Related Art Conventionally, there are contact type and non-contact type bar code readers for reading bar codes, and most of the non-contact type bar code readers are laser type. This is to read the barcode by irradiating the barcode with laser scanning light and detecting the reflected light from the barcode.
Such bar code readers include the installation type, the handy type, and the dual type as described above.
The dual-purpose reading device will be described below.

FIG. 9 shows a perspective view of a conventional hand scanner installed. The hand scanner 11 shown in FIG. 9 includes a grip portion 12 and a reading portion 13. A cable 14 extends from the rear end of the grip portion 12 and is connected to a POS system (which is composed of a register, a computer, etc.). It A mechanism for irradiating laser scanning light and detecting reflected light is provided inside the gripping portion 12 and the reading portion 13. Briefly, the laser light generated by the laser diode is rotated by a motor. Irradiation is performed by scanning means such as a polygon mirror, and scanning light in a plurality of directions is emitted as scanning light 15 to the outside from the reading window of the reading unit 13.

Then, the laser scanning light 15 applied to the bar code is reflected by the bar code, is incident on the photodiode through the reading window, and is converted into an electric signal.
The electric signal corresponding to the bar code is processed by the CPU and supplied to the POS system or the like. By the way, in the bar code, the bar part and the space part are U
PC (Universal Product Cod)
e; Universal product code), EAN (European A)
single code; European product code), J
AN (Japan Article Number (c
ode): The products are arranged in a predetermined arrangement standardized by a product (code) common to Japan.

On the other hand, a stand 16 is used as the case where the hand scanner 11 is installed. In the stand 16, a supporting unit 18 is erected on a reading stand 17, and the supporting unit 1
A mounting portion 19 for mounting the grip portion 12 of the hand scanner 11 is formed on the surface 8. That is, the stand 16 faces the operator, and when the hand scanner 11 is installed, laser scanning light is emitted from the reading window of the reading unit 13 toward the reading table 17.

Therefore, FIG. 10 shows an explanatory view of the usage state of FIG. FIG. 10A shows a case where the hand scanner 11 is installed on the reading stand 17 and used.
The label 21 in which the operator 20 has written the barcode 21a on the laser scanning light 15 emitted from the reading unit 13 of No. 1 toward the operator (actually, the label 21 is attached).
Is approached and the surface of the bar code 21a is blocked toward the reading unit 13, so that the reflected light from the bar code 21a portion is incident on the reading unit 13 for reading.

Further, FIG. 10B shows a hand scanner 11
The figure shows a case where the operator 20 grips and uses the hand scanner. The operator grips the gripping part 12 of the hand scanner 11, and the reading window of the reading part 13 is displayed on the bar code 21a of the label (object) 21.
The laser scanning light is emitted by focusing on the part.

Next, FIG. 11 shows an explanatory view of a conventional hand scanner having another shape. FIG. 11A shows a stationary type scanner 22, which is a box-shaped housing 22a.
Can be installed on the reading table 23 as it is, and the width of the device is such that the operator can hold it with one hand. The scanner 22 is provided on one side with a reading window 22b (see FIG. 11B), and the laser scanning light 24 is emitted in the side direction.
Therefore, the operator 20 positions the bar code 21a portion of the label (object) 21 with respect to the laser scanning light 24 emitted from the scanner 22 fixed on the reading table 23, thereby causing the bar code 21a to be read. .

Further, FIG. 11B shows a state in which the operator 20 holds the housing 22a portion with the reading window 22b outside with respect to the scanner 22 of FIG. 11A.
The bar code 21a portion of the label (object) 21 is irradiated with the laser scanning light 24 from 2b to read the bar code 21a.

[0011]

However, as shown in FIG.
In the hand scanner 11 shown in (A) and (B), the reading window of the reading unit 13 is located in the direction of the operator 20 in the installed state, and the gripping unit 12 is located on the back side thereof. When the operator 20 grips the grip portion 12, it is necessary to change the holding once, or it is necessary to extend the hand to the grip portion 12 on the back side and directly grip the grip portion 12 to change the direction. In addition, FIG.
Similarly, when the scanner 22 shown in (A) and (B) is also grasped from the stationary state, the scanner 2 is held or the housing 2 of the scanner 22 is held.
It is necessary to extend the hand to the back side of 2a and directly grasp it to change the direction. In this way, the hand scanner 11,
22 has a problem in that the gripping performance is poor when gripping, and there is a problem in that the cable 14 extends from the rear end of the gripping part 12 and becomes an obstacle during gripping, resulting in poor gripping performance. .

The support 34 is vertically formed with a width substantially equal to the width of the casing 34 and integrally formed, and fulcrum notches 44a and 44b are formed at the top end portions of the support portions 43a and 43b. This fulcrum notch 44
a and 44b, the protrusions 40a and 4 of the barcode reading device 32
The barcode reading device 32 is rotatably supported by the stand 33 by positioning 0b in the mounted state.

At this time, the support portion 43a of the stand 33,
A protruding stopper 45 is formed as a positioning member between 43b, and rotates the barcode reading device 32 (the housing 3
The position of the reading window 37 is made constant by playing the role of positioning in 4).

Here, FIG. 2 shows an internal block diagram of FIG. In FIG. 2, the bar code reader 32 is connected to an electric power source section 52 from an external electric power source through an outlet cable 51 and converted into direct current.
4. Power is supplied to the decoder 55. Laser light source 53
Irradiates the optical unit 56 including a laser diode with a laser beam, which is configured by a polygon mirror, for example.

The polygon mirror 56 is rotated by a motor 54, and scans the laser light from the laser light source 53 in a plurality of directions while scanning the bar code 46a through the reading window 37.
The label 46 described with is irradiated.

The light reflected from the bar code 46a is received by the light receiving section 5.
The light is received at 7, converted into an electric signal, and sent to the decoder 55 as bar code data. The decoder 55 demodulates the bar code data. The decoder 58 generates a termination sound when the demodulation process is completed,
The display portions 39a and 39b are turned on. Also, the decoder 5
Reference numeral 5 sends the demodulated signal to an external POS (Point of Sale) system via the interface circuit 59.

Here, FIG. 3 shows an explanatory view of the relationship between the center of gravity of the bar code reading apparatus in FIG. 1 and the stand engaging position. FIG. 3 is a schematic side view of the bar code reading device 32. When the barycenter G of the bar code reading device 32 is substantially the center of the reading unit 36, the bar code reading device 32 is engaged with the fulcrum notches 44a and 44b of the supporting portions 43a and 43b of the stand 33.
