Abstract

PURPOSE:To allow this handy scanner to correspond to respective processing methods for a using place and data to be read out. CONSTITUTION:A body part 1 having a light emitting means 4 for irradiating a bar code 5, a light receiving part 6 for receiving reflected light from the bar code 5, an amplifying means 7 for amplifying an output signal from the part 6, a binarizing means 8 for binarizing a signal outputted from the means 7, and a reading means 9 for reading the binarized signal and a communication type hand holding part 2 having a communication means 10 for transmitting read data from the means 9 to a host computer at real time and receiving a signal from the host computer are attachably/detachably combined. When the hand holding part 2 is detached and a storage type hand holding part 3 having a storage means 12 for storing the read data is combined with the body part 1, mobility for a purpose requiring a wide moving range is increased.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handy scanner for reading bar codes.

0002

2. Description of the Related Art In recent years, handy scanners have been increasingly used in various businesses such as POS, logistics, and production management. Among these, there are cases in which interpretation data must be sent to a host computer in real time via a communication cable for processing in a relatively narrow range, such as in retail operations at a store, and cases in which reading data is particularly difficult to read in a relatively narrow range, such as inventory management in a warehouse. There are cases where real-time processing of data is not required, and primary interpretation data is stored and later processed all at once.

0003

Problem to be Solved by the Invention Conventionally, there was a problem in that two different types of handy scanners had to be prepared for the above two types of interpretation data processing.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a handy scanner that can process data in two ways with one scanner.

[0005]

[Means for Solving the Problems] In order to achieve this object, the handy scanner of the present invention includes a main body having a light receiving section, an amplifying means, a binarizing means, and an interpreting means, and a host computer. It has a configuration in which a communication-type hand-held part having a communication means or an accumulation-type hand-held part having a storage means for temporarily accumulating reading data are detachably combined.

[0006]

[Operation] With this configuration, the hand-held parts having different functions can be used interchangeably with respect to one main body part, so that it can be used depending on the situation.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1(a) is an internal configuration diagram of a handy scanner according to an embodiment of the present invention, and is an example in which a communication type hand-held portion is combined with a main body portion. This combination is suitable for cases where reading data must be sent to a host computer via a communication cable and processed in real time in a place with a narrow range of movement, such as retail work at a store.

FIG. 1(b) is an internal configuration diagram of the same handy scanner, and is an example in which a storage type hand-held portion is combined. This combination is suitable for locations with a wide range of movement, such as inventory management in warehouses, and for cases in which reading data can be temporarily stored and then processed all at once.

In these figures, 1 is the main body, 2 is the communication type handheld part, 3 is the storage type handheld part, and 4 is the wavelength 660n.
5 is a bar code printed on the surface of the article; 6 is a light receiving section composed of an image sensor; 7 is an amplifier circuit; 8 is 2 Value conversion circuit, 9 is 8-bit CPU, 1
0 is a communication circuit, 11 is a communication cable such as RS232C,
Reference numeral 12 represents a storage means constituted by a semiconductor memory or the like for storing read data, and 13 represents a battery.

The operation of the main body will be explained below with reference to FIG. 1(a). The irradiated light from the light emitting section 4 illuminates the barcode 5. The reflected light from the barcode 5 forms an image on the image sensor of the light receiving section 6. The signal from the light receiving section 6 is amplified 54 times by an amplifier circuit 7 and then sent to a binarization circuit 8 where it is binarized. This binary signal is read by the CPU 9. FIG. 1(a) shows a handy scanner in which a communication type handheld part 2 is combined with this main body part 1, and the reading data read by the CPU 9 is sent to the communication circuit 10 of the communication type handheld part.
and is transmitted in real time to a host computer (not shown) via communication cable 11. Also, Figure 1
In the handy scanner shown in FIG. 3B, the storage type handheld section 3 is integrated, and the reading data sent from the CPU 9 is stored in the memory 12. In this case, since there is no cable for supplying power, the battery 13 is built into the storage type handheld part. Ultimately, the read data stored in this memory 12 is sent off-line to a host computer for processing.

FIG. 2(a) shows a communication type hand-held portion 2 in the main body portion 1.
Fig. 2(b) is a configuration diagram showing how the main body part 1 is combined.
FIG. 3 is a configuration diagram showing how the storage type hand-held unit 3 is combined with the storage type hand-held unit 3.

0012

As described above, the present invention provides a main unit having an image sensor, an amplifying means, a binarizing means, and an interpreting means, and a communication type hand-held unit or an interpreter having a communication means with a host computer. By configuring the storage-type hand-held part having storage means for temporarily storing data to be combined as necessary, the method of processing read data can be easily changed, and a versatile handy scanner can be realized.
