Description

  The present invention relates to a bar code reader, and more particularly to a bar code reader having a function of reading a bar code and notifying a result of the reading.

Bar code readers (hereinafter also referred to as bar code readers) are used in POS systems, registers, handy terminals, mobile phones, and the like.
For example, in a convenience store or a supermarket, a barcode attached to a product is read by a barcode reader, and transaction information such as a product code included in the barcode is acquired.
Further, along with the acquisition of the transaction information, the user is informed that the reading has succeeded or has failed.

Conventionally, as a notification method for notifying the user of such a reading result, for example, the following method is used.
(1) Output sound from a speaker.
(2) Turn on the LED provided in the barcode reader.
(3) Characters and figures are displayed on a display device arranged at a position different from the barcode reader.
(4) Vibrating a vibrator provided in the barcode reader.
(5) The protrusion which contacts an operator is protruded.

Patent Document 1 describes a POS system that confirms whether or not a bar code is normally read by the method (4) or (5).
Further, Patent Document 2 describes a barcode scanner that informs a user of normality / abnormality of a reading result by the method (4).

JP-A-8-293069 JP-A-11-110469

However, such a conventional notification method has the following problems.
(1) In the method of notifying the reading result by sound, if the ambient noise is large, the sound may not be audible, and if another adjacent barcode reader is used, the sound may not be heard. In some cases, it was misrecognized.
(2) In the method of visually confirming the result of reading by turning on the LED or displaying the reading result on a display device arranged at a position different from the bar code reader, the operator can read the bar code given to the product at the time of reading. It was necessary to point the line of sight toward the LED to the LED of the barcode reader or the screen of the display device, and it took time to check the reading result.
(3) The confirmation by vibration of the vibrator or the confirmation by protrusion of the protrusion differs depending on whether the vibration pattern or protrusion pattern is normal reading or reading error, so it waits for a certain time until it can be confirmed which pattern it is. It was necessary, and it took time to check the reading result.

In particular, when confirming the reading result visually or when confirming the reading result by vibration or the like, it takes a certain amount of time for confirmation, so it takes time to move to reading the barcode of the next product etc. It was hanging.
Also, when reading barcodes of multiple products continuously at convenience stores, etc., the line of sight toward the barcode is moved to the screen of the display device to confirm the reading result, and then the line of sight is barcoded. Returning to [2] places a heavy operational burden on the operator, and the transaction processing efficiency is not good.

  Therefore, the present invention has been made in view of the above circumstances, and reduces the operation burden so that the operator's line of sight is not changed regardless of the presence or absence of ambient noise. It is an object of the present invention to provide a barcode reading apparatus that can confirm a barcode reading result in a short time.

According to the present invention, a reading control unit that detects reflected light that is reflected by the barcode reading surface and incident on the reading port, and a reading result of the barcode is determined from the detected reflected light, and data included in the barcode is obtained. A data analysis unit to be acquired, and a reading result output unit that outputs a reading result output light having an irradiation pattern corresponding to the barcode reading result determined by the data analysis unit from the reading port. A barcode reader is provided.
According to this, since the reading result output light indicating the reading result of the bar code is output from the same reading port where the reflected light for reading the bar code is incident, the operator of the bar code reading device displays the reading result. Easy and reliable confirmation.

The reading result output unit emits light from a light source, an irradiation pattern forming unit that forms the irradiation pattern to output reading result output light corresponding to the reading result, and the light source. An irradiation control unit that converts light into read result output light using the formed irradiation pattern and outputs the light is characterized.
According to this, since the operator visually confirms the reading result, even when surrounding noise is anxious, the operator can confirm the reading result more quickly and reliably than the notification by sound.

Further, the reading result includes a first result indicating that the reading of the barcode is successful and a second result indicating that the reading of the barcode is failed, and the irradiation pattern forming unit includes the first result. A first pattern forming unit for forming a first irradiation pattern for outputting a reading result output light corresponding to the result; and a second irradiation pattern for outputting a reading result output light corresponding to the second result. A second pattern forming unit to be formed, and the irradiation control unit selects one of the first pattern forming unit and the second pattern forming unit based on the reading result, and the selected irradiation pattern Is used to output reading result output light.
According to this, since the reading result output light having the irradiation pattern corresponding to the success or failure of the barcode reading is output, the operator can easily confirm the success or failure of the reading.

  The reading result output unit includes: a light source that emits light; a rotating body that has a reflecting surface that reflects the light emitted from the light source toward the reading port; and the rotating body at a predetermined speed. A rotating motor, and a concavo-convex portion corresponding to the irradiation pattern and changing the reflection direction of the light emitted from the light source is formed on the reflecting surface of the rotating body. By rotating, reading result output light corresponding to the reading result output from the reading port is formed by the whole reflected light that is reflected by hitting the uneven portion of the reflecting surface.

  The irradiation pattern forming unit includes a display filter having a light transmission pattern corresponding to the reading result, the display filter is disposed between the light source and the reading port, and the irradiation control unit By irradiating the display filter with light emitted from a light source, reading result output light having a light transmission pattern corresponding to the reading result is output from the reading port.

  In addition, the reading result includes a first result indicating that the reading of the barcode is successful and a second result indicating that the reading of the barcode is failed, and the display filter includes the first result. A first filter having a corresponding light transmission pattern; and a second filter having a light transmission pattern corresponding to the second result, wherein the irradiation control unit includes a first filter and a second filter based on the read result. A display filter disposed between the light source and the reading port is selected, and the reading result output light is output using the selected display filter.

  Further, the light source is composed of a plurality of light emitting elements arranged in a matrix, and the irradiation pattern formed by the irradiation pattern forming unit is arranged at a position corresponding to the reading result by the irradiation control unit. Further, it is formed by emitting only a plurality of light emitting elements, and reading result output light having an irradiation pattern formed by light emission of the light emitting elements is output from the reading port.

  According to the present invention, the reading result output light having the irradiation pattern corresponding to the barcode reading result is output from the same reading port as the reading port through which the reflected light is incident when reading the barcode. Can easily and surely confirm the reading result while keeping the same line of sight as the reading operation, and can reduce the burden on the operator. In addition, since the reading result can be confirmed visually, even if there is noise in the surroundings, it can be surely confirmed, and the next barcode reading operation can be started in a shorter time.

<Configuration of Barcode Reader of the Invention>
FIG. 1 is a block diagram showing the configuration of an embodiment of the barcode reader according to the present invention.
The barcode reader (barcode reader) 200 is connected to the information processing device (host device) 100 using a network or a dedicated cable, and transmits and receives various information between the two.
The host device 100 is a device that performs information processing such as a POS, a personal computer, a register, and a handy terminal, for example. The host device 100 mainly receives barcode information read by the barcode reading device 200 and uses the received information as the received information. This is a device that performs calculations, display, printing, and the like.

The host device 100 mainly prints a display unit 102 that displays input information, calculation information, output information, and the like, an operation unit 104 that inputs characters and numbers, and a control instruction, and transaction information, a receipt, and the like. It comprises a communication unit 103 that transmits and receives data between the printing unit 105 and the barcode reader 200, and a control unit 101 that controls the operation of each of these functional blocks.
As the display unit 102, an LCD or a CRT is used.
For the operation unit 104, a keyboard, a touch panel, or the like is used.
The communication unit 103 can use various communication methods currently used, wired or wireless, and is a part that communicates with other input devices and output devices in addition to the barcode reader.

In particular, barcode reading start request information, reading stop request information, ringing request information, vibration request information, notification condition setting information, and the like are transmitted from the communication unit 103 to the barcode reading apparatus 200.
On the other hand, the barcode reading apparatus 200 transmits a reading result 225, reading data 226, and the like to the communication unit 103.

The bar code reader 200 (bar code reader) mainly reads a bar code attached to a product, analyzes the read bar code, reproduces data included in the bar code, and successfully reproduces the data. In this case, the read data is transferred to the host device 100, and the read result is reported to the operator by various methods.
The present invention is characterized in that the reading result is reported by being displayed on a barcode reading surface, that is, on a paper surface on which the barcode is printed.
However, conventional notification by sounding, notification by vibration, and notification by displaying the result on the display unit (102 or 211) may be used in combination.

The barcode reader 200 mainly includes a communication unit 201, a control unit 202, an operation unit 203, a data analysis unit 205, a reading control unit 206, four notification units (209, 2210, 211, 230), and a storage unit 220. Is done.
The four reporting parts are parts for notifying the operator of the reading result, that is, whether the bar code has been normally read or not read. In FIG. 1, in FIG. The unit 210, the display unit 211, and the reading result output unit 230 are configured.
The vibration unit 209, the sounding unit 210, and the display unit 211 may not be provided.

The barcode reader communication unit 201 is a part that transmits and receives various data to and from the communication unit 103 of the host device 100.
The control unit 202 controls the operation of each functional block of the barcode reader 200, and is mainly realized by a microcomputer such as a CPU, ROM, RAM, I / O controller, and timer.
Further, various functions of the barcode reader of the present invention are executed by the CPU organically operating various hardware based on a control program stored in advance in the storage unit 220.

The operation unit 203 is a part for manually instructing input of the start or end of the barcode reading process. For example, a push button switch is provided at a part where the barcode reader main body is held by hand.
In this case, the barcode reading process is started by the reading control unit 206 when the push button switch is pressed, and the reading process is ended when the switch is released.

The data analysis unit 205 is a part that determines the reading result of the barcode from the reflected light detected by the light receiving unit 208, and also converts the barcode from the read barcode to the barcode based on a predetermined barcode standard. This is the part that acquires (reproduces) the contained data. The barcode standard is not particularly limited, and for example, EAN, JAN, CODE39, two-dimensional code, etc. can be used.
When the data is normally acquired by analyzing the barcode, the acquired data is stored in the storage unit 220 as the read data 226.
Further, when data can be normally acquired, for example, information indicating “success (OK)” is stored as the reading result 225. On the other hand, when data cannot be acquired from the barcode, that is, when reading of the barcode fails, information indicating, for example, “failure (NG)” is stored as the reading result 225. The read result 225 and the read data 226 are transferred to the host device 100.

The reading control unit 206 is a part that reads a barcode, and mainly includes a light emitting unit 207 and a light receiving unit 208. This is the part that reads the barcode in the same way as a conventional barcode reader. The light emitted from the light emitting unit 207 strikes the barcode reading surface, and the reflected light from the barcode reading surface is received by the light receiving unit 208. Read the barcode.
In the light receiving unit 208, the light corresponding to the barcode is converted into an electric signal and provided to the data analysis unit 205.
As the light emitting unit 207, for example, a light emitting element such as an LED or a laser diode can be used.
As the light receiving unit 208, for example, a photoelectric conversion element such as a CCD, a CMOS sensor, or a CMOS camera can be used.
In addition, without the light emitting unit 207, natural light is reflected on the barcode reading surface, and the light incident on the reading port of the barcode reader among the reflected light from the barcode reading surface is detected by the light receiving unit 208. May be.

The vibration unit 209 is a part that applies vibration to the main body of the barcode reader, and for example, a vibration member conventionally used in a mobile phone or the like can be used.
Further, the vibration unit 209 changes the vibration pattern based on the reading result 225.
For example, when the barcode is successfully read, a vibration having a length of about 1 second is given only once. If the barcode reading fails, the vibration for 1 second is repeated five times.
The sounding unit 210 is a part that outputs a sound corresponding to the reading result 225, and a speaker is used. For example, if the barcode is successfully read, a beep is sounded only once. If the reading of the bar code fails, a beep sound of about 1 second is sounded 5 times continuously. The output sound is not a single sound such as a beep sound, but may be a synthesized sound.

The display unit 211 is a part that displays the reading result with characters, figures, or symbols, and an LCD can be used. Alternatively, in order to provide the barcode reader 200 with a display unit, it is preferable that the barcode reader 200 be as light as possible, and thus an LED may be used.
In the case of the LED, the reading result may be displayed by changing the lighting color, the number of lighting times, or the lighting length.
For example, when reading is successful, the blue LED is lit for only 1 second, and when reading is unsuccessful, the red LED blinks five times.
As described above, the vibration unit 209, the sounding unit 210, and the display unit 211 may be the same as the conventional method for notifying the reading result, and the cost, function, or weight of the barcode reader is used. It is not necessary to provide everything from the viewpoint of the above.

The reading result output unit 230 is a part that displays the reading result of the barcode on the barcode reading surface (the paper surface on which the barcode is printed) through the reading port of the barcode reader. The code reading surface is irradiated with light, and an image of an irradiation pattern corresponding to the reading result is displayed.
For example, when the barcode is successfully read, the barcode reading surface is irradiated with light from the reading port, and an image of an irradiation pattern (character) of “success” or “OK” is displayed.
In the case of failure, the barcode reading surface is irradiated with light from the reading port, and an image of an irradiation pattern (character) of “failure” or “NG” is displayed on the barcode reading surface.

  The barcode reading surface is, for example, a wrapping paper of a product on which a barcode is displayed or an affixed label on which the barcode is printed, and light emitted from the light emitting unit 207 is irradiated when the barcode is read. It is also a surface. That is, the traveling direction of the light emitted from the light emitting unit 207 for reading the barcode and the traveling direction of the light emitted from the light source 231 of the reading result output unit 230 for displaying the reading result are determined by the operator. It is preferable to match so that the line of sight is not changed for confirmation of the reading result.

The reading result output unit 230 mainly includes a light source 231, an irradiation pattern forming unit 232, and an irradiation control unit 233.
The light source 231 is a portion that emits light, and for example, an LED, a laser diode, a miniature bulb, or the like is used.
The irradiation pattern forming unit 232 is a part that forms an irradiation pattern of a display image corresponding to the barcode reading result. The irradiation pattern of the display image formed here is displayed as an image on the barcode reading surface. The irradiation pattern of the formed display image is, for example, the letters “OK” or the letters “NG”.
Although details will be described later, for example, a rotating body provided with a large number of mirrors having a plurality of concave and convex patterns, a display filter having a plurality of display image irradiation patterns capable of transmitting light, and the like correspond to the irradiation pattern forming unit 232. .

The irradiation control unit 233 is a part that converts the light emitted from the light source into read result output light by using the formed irradiation pattern and outputs it. In other words, the light source 231 guides the light emitted from the light source from the reading port of the barcode reader in the direction of the barcode reading surface, and displays a display image corresponding to the reading result on the barcode reading surface. This is a part that controls the irradiation pattern forming unit 232.
For example, it is a part that performs control of output and stop of light from the light source, rotation control of a rotating body, which will be described later, and selection control of a display filter to be used.

When the barcode reading result 225 is stored in the storage unit 220 by the data analysis of the data analysis unit 205, the irradiation pattern formation is performed so that the irradiation control unit 233 forms a display image pattern corresponding to the reading result. An instruction is given to the unit 232. For example, when the reading result is “success”, a display filter having a light transmission pattern corresponding to the characters “success” is arranged between the light source and the barcode reading surface. Thereafter, light is emitted from the light source 231 for a certain period of time.
As a result, the emitted light is applied to the display filter, passes through only the light transmission pattern portion of the character “success” of the display filter, is output from the reading port, and hits the barcode reading surface ahead of it. , “Success” is displayed on the barcode reading surface.
The operation of the reading result output unit 230 described above is an example. Some other examples of the read result output unit 230 will be described later.

The storage unit 220 is a part for storing information necessary for the operation of the barcode reader 200 of the present invention, and a storage medium such as a semiconductor storage element such as a ROM, a RAM, or a flash memory, a hard disk, or a memory card. Used.
Information that needs to be fixedly stored in advance, such as programs, is stored in a ROM, flash memory, or hard disk, and information that can be rewritten, such as read results 225 and read data 226, is stored in a rewritable memory (RAM, hard disk). Saved.
In the present invention, the storage unit 220 mainly stores notification conditions 221, reading results 225, and reading data 226 as shown in FIG. 1.

The notification condition 221 is information for determining how to notify the barcode reading result, and includes, for example, notification type information 222, irradiation pattern information 223, and irradiation time information 224.
FIG. 2 shows an explanatory diagram of an embodiment of the notification condition of the present invention.
The report type information 222 is information in which a means for notifying the reading result is set, and includes reading normal setting information (1) and reading error setting information (2).
The normal reading setting information (1) is information for setting a reporting means when the barcode reading is successful, and the reading error setting information (2) is information for setting the reporting means when reading is unsuccessful. It is.

In the embodiment shown in FIG. 1, four notification means (209, 210, 211, 230) are shown as the notification means of the reading result. However, the control unit 202 is not limited to this setting information (1) or (2 ) To recognize which reporting method to use.
In the two setting information shown in FIG. 2, “sound” is information for determining whether or not to make a report using the sound ringing unit 210. For example, when “sound” = “1”, a report by sound When “sound” = “0”, it means that notification by sound is not performed.
“Display” is information for determining whether to make a report using the display unit 211, and “Vibration” is information for determining whether to make a report using the vibration unit 209. Yes, “irradiation” is information that determines whether or not to report using the reading result output unit 230.

The specific example “1, 0, 0, 1” of “reading normal setting information (1)” shown in FIG. 2 is obtained by two means of notification by the sounding unit 210 and notification by the reading result output unit 230. , Meaning that the reading is successful.
Further, the specific example “0, 0, 1, 1” of “reading error setting information (2)” has failed to be read by two means of notification by the vibration unit 209 and notification by the reading result output unit 230. It means to report what happened.
These setting information may be fixedly set in advance at the start of use so that they cannot be changed. However, these setting information is stored in a rewritable memory such as a hard disk and is recognized by each operator. It may be possible to change the setting of an easy-to-use notification method at any time.

The irradiation pattern information 223 in FIG. 2 is information in which a pattern of a display image when the reading result is displayed by the reading result output unit 230 is set.
FIG. 2 shows normal pattern information (1) and error pattern information (2).
Normal pattern information (1) indicates irradiation pattern information to be displayed when bar code reading is successful, and is set in a format such as a character, graphic, symbol, or pattern code.
Here, two specific examples are shown. For example, in the case of a character, characters “OK” and “success” are set, and in the case of a pattern code, “00000001” meaning the character “OK”. Or, “00000010”, which means the character “success”, is set.

  The error time pattern information (2) indicates information of a pattern to be displayed when the reading of the barcode has failed. The characters “NG” and “failure” as shown in FIG. A pattern code, figure, or symbol corresponding to is set.

For example, when the pattern code (00000001) is set as the normal pattern information (1), the reading result output light having the irradiation pattern corresponding to the characters “OK” when the barcode is successfully read. Is output from the reading port as a reading result.
Further, when the pattern code (00001111) is set as the error pattern information (2), the reading result output light having the irradiation pattern corresponding to the character “failure” when the reading of the barcode is failed. Is output from the reading port as a reading result.

The irradiation time information 224 in FIG. 2 is a time during which light is emitted from the light source 231 of the reading result output unit 230.
As shown in FIG. 2, if 200 msec is set as the irradiation time information 224, light is emitted from the light source 231 only for 200 msec, and the irradiation pattern set in the irradiation pattern information 223 is displayed on the barcode reading surface. Only the time (200 msec) is displayed.

<Barcode reading process and result output process>
Here, an outline of the barcode reading process and the reading result output process of the present invention will be described.
FIG. 3 is a schematic explanatory diagram of the barcode reading process and the reading result output process of the present invention.
FIG. 4 is an explanatory diagram of an embodiment of the barcode reading process.
When reading the barcode, the operator places the barcode reader 200 on the barcode reader 200 so that the light emitted from the reading port 303 of the barcode reader 200 strikes the surface 302 on which the barcode 301 is printed (also referred to as a barcode reading surface). Move closer to the cord. When the reading light 311 emitted from the light emitting unit 207 of the reading control unit 206 hits the barcode reading surface 302, the reflected light 312 enters the reading port 303 of the barcode reader and is detected by the light receiving unit 208.

The light detected by the light receiving unit 208 is converted into an electrical signal. When the barcode as an image is recognized from the electrical signal and the analysis is normally performed by the data analysis unit 205, the data included in the barcode is acquired. The
The acquired data is stored in the storage unit 220 as read data 226 and transferred to the host device 100 via the communication unit 201.
As described above, when the data analysis ends normally and reading is successful, information indicating “success” is stored as the reading result 225.

On the other hand, if the data included in the barcode cannot be acquired by the analysis by the data analysis unit 205, that is, if the barcode reading fails, information indicating “failure” is stored as the reading result 225. To do.
Up to here is the outline of the barcode reading process of the present invention.

Next, a process for displaying the reading result on the barcode reading surface will be described.
FIG. 5A shows an example of a result display when reading is successful, and FIG. 5B shows an example of a result display when a reading error occurs.
As described above, when the reading result 225 is stored, the control unit 202 instructs the reading result output unit 230 to output the reading result.

The irradiation control unit 233 of the reading result output unit 230 checks the reading result 225 stored in the storage unit, and reads the irradiation pattern information 223 corresponding to the reading result.
The read irradiation pattern information 223 is given to the irradiation pattern forming unit 232. The irradiation pattern forming unit 232 prepares an irradiation pattern corresponding to the given irradiation pattern information 223. For example, when an irradiation pattern is formed using a display filter, a display filter having a light transmission pattern (read result transmission pattern) corresponding to the read result is provided between the light source 233 and the reading port 303 of the barcode reader. Arrange.
Thereafter, the irradiation controller 233 emits light from the light source 231 for the time of the irradiation time information 224.

For example, when the light emitted from the light source 231 passes through a light transmission pattern on the display filter, it is converted into reading result output light 313 for displaying characters and the like of the reading result, and is output from the reading port 303 of the barcode reader to the outside. Is output.
At this time, if the operator points the barcode reader in the same direction as the barcode reading direction, the reading result output light 313 emitted from the reading port 303 strikes the barcode reading surface 302. become. That is, as shown in FIG. 5A or FIG. 5B, characters or the like as a result of reading are displayed on the barcode reading surface 302.

Since a series of processing until the operator reads the barcode and the reading result is displayed as shown in FIG. 5 is performed in real time by the CPU or the like, the time until the reading result shown in FIG. 5 is displayed. Is instantaneous, and can be performed within 100 ms, for example.
If the reading result is displayed in such a short time, the operator moves the line of sight to the barcode reading surface in order to read the barcode, and then quickly and quickly reads the reading result while keeping the line of sight. It is possible to confirm visually, and the burden on the operator for confirming the reading result can be reduced.

<Description of Example of Reading Result Output Unit>
Hereinafter, several embodiments for outputting the barcode reading result will be described.

Here, a configuration is shown in which light emitted from a light source is reflected by a rotating body having a reflection surface on the surface thereof in the direction of the reading port of the barcode reader, and the reading result is displayed on the barcode reading surface.
FIG. 6 is a schematic explanatory diagram of the read result output unit according to the first embodiment of the present invention.
In FIG. 6, the read result output unit 230 mainly includes an irradiation position designation unit 502, a laser diode 501, a rotating body 503, a motor 504, a first mirror surface 505, and a second mirror surface 506. The The surface of the rotating body is circular, and the reflecting surface formed on the surface of the rotating body is composed of two separated mirror surfaces.

The laser diode 501 corresponds to a light source, and light emitted from the laser diode first travels in the direction of the rotating body, strikes the reflecting surface of the rotating body, and is reflected in the direction of the reading port. This reflected light corresponds to the read result output light 313 in FIG.
The irradiation position designation unit 502 is a member that accommodates the light source 501 and determines the light irradiation position, and moves the position of the light source in FIG. 6 in the vertical direction.
The irradiation position designation unit 502 includes, for example, a spring and an electromagnet for expanding and contracting the spring. When the electromagnet is not energized, the position of the light source is set to be the successful irradiation position in FIG.
On the other hand, when the electromagnet is energized, in the case of FIG. 6, the spring is extended, the light source 501 is moved downward, and the position of the light source is set to the error time irradiation position of FIG.

The successful irradiation position is the position of the light source when the barcode is successfully read, and the light emitted from the light source travels toward the rotating body 503, hits the first mirror surface 505, and the reading port 303. A reading result (for example, characters “OK”) reflected on the barcode reading surface 302 and indicating that the reading has been successful is displayed on the barcode reading surface 302.
The first mirror surface 505 and the second mirror surface 506, which are reflection surfaces, have a large number of irregularities, and the rotation direction of the rotating body 503 changes the reflection direction of light hitting the first or second mirror surface. The irradiation pattern of the reading result is displayed on the barcode reading surface while the rotating body 503 is rotated once. The concavo-convex portion corresponds to the irradiation pattern and is a concavo-convex pattern on the surface that changes the reflection direction of the light emitted from the light source.
That is, the two mirror surfaces 505 are members that are provided on the surface of the rotator 503 and change the light reflection direction by the uneven portions of the reflection surface to form an irradiation pattern as a reading result.
In addition, when the rotating body makes one rotation, reading result output light corresponding to the reading result output from the reading port is formed by the entire reflected light that has been reflected by hitting the uneven portion of the reflecting surface.

The rotating body 503 is rotated in a certain direction (counterclockwise direction in FIG. 6) at a predetermined speed by a motor 504 disposed below the rotating body 503 as shown in FIG.
In the case of FIG. 6, the rotating body 503, the motor 504, and the first and second mirror surfaces (505 and 506) correspond to the irradiation pattern forming unit 232.

If the first result indicating that the barcode is successfully read is “OK”, the first mirror surface 505 in FIG. 6 outputs the read result output light corresponding to the first result (OK). This corresponds to a first pattern forming unit that forms a first irradiation pattern for the purpose.
At the same time, if the second result indicating that the barcode reading has failed is “NG”, the second mirror surface 506 in FIG. 6 outputs the read result output light corresponding to the second result (NG). This corresponds to a second pattern forming portion for forming a second irradiation pattern for the purpose.

  Here, the irradiation control unit 233 selects one of the first pattern forming unit (first mirror surface 505) and the second pattern forming unit (second mirror surface 506) based on the reading result. For example, if the reading result is successful, the first pattern forming unit (first mirror surface) is selected. Then, in order to output the reading result output light using the selected first pattern forming unit (first mirror surface), the irradiation position specifying unit 502 is operated so that the position of the light source faces the first mirror surface. Move to the successful irradiation position.

The irradiation position at the time of error is the position of the light source when the barcode reading fails. When there is a light source at this position, the light emitted from the light source travels toward the rotating body 503, hits the second mirror surface 506, and is reflected toward the reading port 303 and the barcode reading surface 302. At this time, by rotating the rotating body 503, a reading result (for example, “NG” characters) indicating that reading has failed is displayed on the barcode reading surface 302.
Therefore, in the case of FIG. 6, the irradiation pattern corresponding to the reading result when the barcode is successfully read is formed by the concave / convex pattern of the first mirror surface 505 while the rotating body is rotated once, and the second mirror surface With the concavo-convex pattern 506, an irradiation pattern corresponding to the reading result when the barcode reading fails is formed.

The position control of the light source by the irradiation position designation unit 502, the light emission control from the laser diode 501, and the rotation control of the rotating body by the motor 504 are performed by an irradiation control unit 233 not shown in FIG.
The function of the irradiation control unit 233 is realized by the CPU operating each hardware based on the three control programs stored in the storage unit 220 in advance.
The reading result output light 313 reflected by the rotator 503 in FIG. 6 is emitted to the outside from the reading port 303 of the barcode reader shown in FIG. 3, and this direction is emitted from the light emitting unit 207 during barcode reading. The reading light 311 is in the same direction.
Therefore, if the direction of the barcode reader that the operator points at the time of barcode reading is kept as it is for a certain time, the reading result output light 313 for displaying the barcode reading result is the barcode reading. The surface 302 will be irradiated.

FIG. 7 shows a configuration diagram of the second embodiment in which two fixed laser diodes (501-a, 501-b) are provided instead of the irradiation position specifying unit 502 of the first embodiment.
The first laser diode 501-a is a light source for displaying the success of reading, and is arranged at the same position as the successful irradiation position in FIG. 6.
The second laser diode 501-b is a light source for displaying reading failure and is arranged at the same position as the error irradiation position in FIG. 6.
The same member as that of the first embodiment of FIG. 6 may be used for the rotating body 503, the motor 504, and the first and second mirror surfaces (505, 506).
Here, the first laser diode 501-a and the first mirror surface 505 correspond to the first pattern forming portion, and the second laser diode 501-b and the second mirror surface 506 are the second pattern forming portion. It corresponds to.

In the second embodiment, the emission control of the first laser diode 501-a may be performed when the barcode reading is successful, and the emission control of the second laser diode 501-b may be performed when the barcode reading fails.
In this case, it is necessary to provide two laser diodes, but since it is not necessary to provide the irradiation position designation unit 502 as shown in FIG. 6, the complicated circuit for controlling the spring and the electromagnet is omitted, and the number of hardware components is reduced. Therefore, it is not necessary to control the position of the light source, and hardware and control software can be simplified and reduced in cost compared to the first embodiment.

  It should be noted that since two reading results, “success” and “failure”, are sufficient, in the second embodiment, the number of laser diodes is two, but it is necessary to display three or more reading results. In this case, laser diodes and mirror surfaces may be provided as many as the number corresponding to the number of reading results (three or more).

FIG. 8 is a configuration diagram of Example 3 using a rotary display filter.
FIG. 9 is an explanatory diagram showing the positional relationship among the irradiation pattern forming unit 232, the reading port 303, and the barcode reading surface 302.
Here, the irradiation pattern forming unit 232 includes a rotating body 503, a display filter 510, and a motor 504.
The display filter 501 is attached to the surface of the rotating body 503, and the rotating body 503 is rotated by a motor. The surface of the rotating body may be circular, but may be a polygon having the same number of planes as the display filter.
The light source 501 is disposed substantially at the center of the rotating body, and the direction of the emitted light is always the direction of the reading port 303 of the barcode reader 200 without rotating.
As the display filter 510, for example, an optical filter, an LCD, or the like may be used.

In FIG. 9A, the rotator 503 has four surfaces, and the display filters 510 (P1, P2, P3) having different light transmission patterns (also referred to as read result transmission patterns) on each surface. , P4).
However, the number of surfaces of the rotating body 503 is not limited to four, and may be three, or five or more.
Further, even when there are four surfaces, it is not necessary to provide display filters 510 on all four surfaces. When two reading results are displayed, the display filters 510 for the respective reading results are displayed on two specific surfaces. May be provided.

FIG. 9B illustrates an example of the display filter 510 and the read result transmission pattern 511 according to an embodiment.
Here, “OK” is the read result transmission pattern 511, which is shown in black in the drawing, but only the black portion is actually a portion that transmits light. As the reading result output light 313 passes through the black portion “OK”, the reading result 320 (OK) is displayed on the barcode reading surface 302 as shown in FIG. 9C.

In FIG. 9A, since the display filter P1 is between the light source 233 and the reading port 303, the reading result 320 corresponding to the irradiation pattern (reading result transmission pattern 511) formed on the display filter P1 is a barcode. It is displayed on the reading surface 302.
In order to display the reading result 320 corresponding to the irradiation pattern formed on the display filter P2, the rotating body 503 is rotated by 90 degrees, and the display filter P2 is disposed between the light source 233 and the reading port 303. .

Similarly, with respect to the other display filters P3 and P4, the rotator may be rotated to arrange a desired display filter between the light source 233 and the reading port 303.
In the case of the third embodiment, the irradiation control unit 233 controls the motor to rotate the rotating body to a predetermined position, and arranges the display filter 510 corresponding to the reading result between the light source 233 and the reading port 303. After that, light may be emitted from the light source 233.
The light emitted from the light source 233 is applied to the display filter 510, passes through the light transmission pattern portion formed on the display filter, and from the reading port, the reading result output light having a light transmission pattern corresponding to the reading result. Is output.

  In this third embodiment, it is necessary to prepare in advance a display filter corresponding to the number of read results to be displayed. However, only one light source is required, and it is not necessary to keep the rotating body 503 continuously rotating at a predetermined speed. Therefore, the hardware configuration and the control software can be simplified as compared with the first embodiment.

FIG. 10 shows a configuration diagram of an embodiment using a plurality of display filters.
FIG. 11 is an explanatory diagram of the positional relationship among the irradiation pattern forming unit 232, the reading port 303, and the barcode reading surface 302.
Here, two light sources (501-a, 501-b) are provided, and two display filters (510-a, 510-b) are fixedly arranged in front of each light source.
Moreover, the reflective mirror 520 is provided in the back and side surface of a light source.
The display filter 510-a is a first filter having a light transmission pattern corresponding to the first result (OK) indicating that reading is successful, and the display filter 510-b is a second result indicating that the reading has failed ( NG) is a second filter having a light transmission pattern.

The first light source 501-a and the first display filter 510-a are configured to display on the barcode reading surface 302 the reading result (for example, OK) when the barcode is successfully read.
Further, the second light source 501-b and the second display filter 510-b are configured to display a reading result (for example, NG) when the reading of the barcode is failed on the barcode reading surface 302. is there.
Here, the display filters (510-a, 510-b) correspond to the irradiation pattern forming unit 232.

As shown in FIG. 9B, the two display filters (510-a, 510-b) are filters having respective reading result transmission patterns 511, and corresponding light sources (501-a, 501-b). ) And the reading port 303.
For example, the first display filter 510-a has a read result transmission pattern 511 “OK”, and the second display filter 510-b has a read result transmission pattern 511 “NG”.

In Example 4, for example, when the barcode is successfully read, the first filter is selected, and light is emitted from the first light source 501-a. At this time, the emitted light passes through the first display filter 510-a, the reading result output light 313 output from the reading port hits the barcode reading surface 302, and a reading result 320 indicating that reading is successful is displayed. The
If reading of the barcode fails, the second filter is selected and light is emitted from the second light source 501-b. At this time, the emitted light passes through the display filter 510-b, the reading result output light 313 output from the reading port hits the barcode 302, and a reading result 320 indicating that reading has failed is displayed.
In the fourth embodiment, it is necessary to provide as many light sources and display filters as the number of read results to be displayed. Compared to Example 1, the hardware configuration and control software can be simplified.

12 and 13 are configuration diagrams of an embodiment using a plurality of laser diodes (light emitting elements).
Here, a plurality of laser diodes (light emitting elements) arranged in a matrix are used as the light source 501. In this case, only a plurality of laser diodes arranged at predetermined positions corresponding to the reading result are turned on (emitted) to form an irradiation pattern corresponding to the reading result with the light source itself. In this case, the light source 501 is also the irradiation pattern forming unit 232.

As shown in FIG. 13A, the light emitted from each laser diode travels in the direction of the reading port 303 as it is and is applied to the barcode reading surface 302.
At this time, as shown in FIG. 13B, only the laser diode located at the position corresponding to the character “OK”, which is the reading result in the light source 501, emits light, thereby reading the reading output from the reading port 303. The result output light 313 is an irradiation pattern of the reading result.
That is, as shown in FIG. 13C, “OK”, which is the reading result, is displayed on the barcode reading surface 302.

FIG. 12 shows a state in which the laser diode at the position corresponding to the character “OK”, which is the reading result displayed when the bar code is successfully read, is lit.
Further, when the barcode reading fails, the laser diode at the position corresponding to the character “NG”, for example, which is the reading result, may be turned on.

  In the fifth embodiment, it is necessary to provide a large number of laser diodes as light sources, but it is not necessary to provide a rotating body, a motor, a display filter, etc., and it is only necessary to control the position of the laser diode to be lit. Compared to 1, hardware and software can be simplified.

<Example of Barcode Reading Process and Result Output Process>
Hereinafter, an embodiment of the barcode reading process and the barcode reading result output process of the present invention will be described.
(1) Processing of Host Device FIG. 14 shows a flowchart of an embodiment of processing executed by the host device.
In the host device, when an operator performs a predetermined input using the operation unit 104, a notification condition setting request, a barcode reading request, a barcode reading stop request, and the like are performed.

In step S <b> 101, the control unit 101 checks whether a notification condition setting request is input from the operation unit 104.
For example, it is checked whether or not there is a depression of a specific key for instructing to input setting of the report condition.
If there is an input indicating this setting request, the process proceeds to step 102.
On the other hand, if there is no input, the process proceeds to step S104.
In step S102, the control unit 101 performs notification condition setting processing. Here, input of information (report type information 222, irradiation pattern information 223, irradiation time information 224) included in the notification condition 221 is accepted from the operation unit 104, and the input information is temporarily stored in a buffer or the like. .

In step S103, the set notification condition is transmitted to the barcode reader 200 via the communication unit 103, and the process returns to step S101. The barcode reader stores the transmitted notification condition in the storage unit 220 (step S203 described later).
In step S <b> 104, the control unit 101 checks whether there is an input from the operation unit 104 that indicates a barcode reading request.
If this read request has been input, the process proceeds to step S105, and if not, the process returns to step S101.

In step 105, information indicating a barcode reading start request is transmitted to the barcode reader 200 via the communication unit 103.
Receiving this reading start request, the barcode reader 200 starts barcode reading processing (step S205 described later).
Here, the reading control unit 206 emits the reading light, receives the reflected light, analyzes the barcode data, outputs the reading result, and the like (steps S232 to S248).

In step S106, the process waits for a barcode reading result to be sent from the barcode reader. If the reading result is received, the process proceeds to step S107. If not, the process proceeds to step S108.
In step S107, the reading result and the reading data sent simultaneously when the reading is successful are stored and displayed on the display unit 102.
Thereafter, the process returns to step S106.

On the other hand, in step S108, it is checked whether or not there is an input from the operation unit 104 indicating a barcode reading stop request.
If there is no such input, the process returns to step S106.
On the other hand, if this input has been made, the process proceeds to step S109, and information indicating a reading stop request is transmitted to the barcode reader 200. Thereafter, the process returns to step S101.

(2) Barcode Reader Processing The program for realizing the barcode reader function is mainly composed of the following main processing (FIG. 15), reading processing (FIG. 16), and reading result output processing programs. It is preferable to execute as a multi-task in relation to transmission / reception and the like.
The reading result output process includes an irradiation notification process (FIG. 17) that is a feature of the present invention, a sound notification process, a display notification process, and a vibration notification process that are conventionally performed. It is preferable to operate independently as a multitask.

FIG. 15 shows a flowchart of one embodiment of the main process of the barcode reader of the present invention.
The main process is a part that executes a process corresponding to the request mainly based on various request information sent from the host device.

In step S <b> 201, the control unit 202 checks whether request information from the host device 100 is received via the communication unit 201. If there is no reception, step S201 is looped.
If the request information is received, the process proceeds to step S202. In step S202, it is checked whether or not the received request information is a notification condition setting request.
When it is a notification condition setting request, the process proceeds to step S 203, and the received notification condition 221 is stored in the storage unit 220.
Thereby, it is set by which means the bar code reading result is reported to the operator.
Then, it returns to step S201.

On the other hand, if the received request information is not a notification condition setting request in step S202, the process proceeds to step S204, and it is checked whether or not the request information is a barcode reading start request.
If the received request information is a reading start request, the process proceeds to step S205, and an activation instruction signifying the start of barcode reading is given to the barcode reader reading processing program. Then, it returns to step S201.
As a result, the barcode reader reading processing program of FIG. 16 is activated, and the barcode reading operation is enabled.

In step S204, if the received request information is not a reading start request, the process proceeds to step S206, and it is checked whether or not the request information is a barcode reading stop request.
If the received request information is a reading cancellation request, the process proceeds to step S207, and if not, the process returns to step S201.
In step S207, an instruction to cancel the barcode reading is given to the barcode reader reading processing program.
Then, it returns to step S201. Thereby, the barcode reading operation is stopped.

FIG. 16 shows a flowchart of one embodiment of the reading process of the barcode reader of the present invention.
Here, reading of the barcode by the reading control unit 206, analysis of the data read by the data analysis unit 205, activation of each notification process of the reading result, and transmission of the reading result and the reading data are mainly performed.

  In step S231, it is checked whether a start instruction is given from the main processing program. If there is no activation instruction, step S231 is looped. If there is an activation instruction, the process proceeds to step S232.

In step 232, reading light is output from the light emitting unit 207 of the reading control unit 206.
As shown in FIG. 3, the reading light 311 is output to the outside from the reading port 303 of the barcode reader.
In step S233, the light receiving unit 208 checks whether or not the reflected light from the barcode is received.

If the reflected light is received by the light receiving unit 208, the process proceeds to step S234, and if not received, the process returns to step S232.
When the reflected light is received, the light is converted into an electrical signal by the light receiving unit 208. For example, a predetermined digitization process is performed on the electrical signal and temporarily stored in the storage unit.

  In step S234, the paper surface detection unit 204 determines whether the barcode can be recognized from the digitized electric signal pattern. Since a bar code is generally a line of a predetermined thickness arranged with a predetermined interval based on a predetermined standard, if the pattern of the received electric signal is confirmed, the received light Thus, it can be determined whether or not the barcode can be recognized.

If it can be recognized as a barcode, the process proceeds to step S237. If it cannot be recognized, the process proceeds to step S235.
In step S237, the data analysis unit 205 extracts a barcode from the received electrical signal pattern and performs a data analysis process for acquiring data included in the barcode.
The specific contents of the data analysis process may be the same as the conventional process, and the contents are omitted.

If the data included in the barcode can be acquired normally by the data analysis processing, information indicating “success” is stored as the reading result 225 in step S238, and the acquired data is stored as the reading data 226. .
On the other hand, if data cannot be acquired by the data analysis process, information indicating “failure” is stored as the read result 225 in step S238.

In step S239, the notification condition 221 stored in the storage unit 220 is read out.
For example, if the reading is successful, the reading normal setting information (1) in the notification type information 222 is read, and in which of the four notification means is used to report the reading result in steps S240 to S246. Judging.

In step S240, it is checked whether or not a notification setting by sound is set. If it is set to report by sound, the process proceeds to step S241 to start the sound notification process.
For example, in the case of the normal reading setting information (1) in FIG. 2, since “1” is set for “sound”, a notification is made by sound.
The sound notification process is preferably performed by a multitask operation, and a predetermined sound may be output by the sound ringing unit 210 for a certain period of time.
Thereafter, the process proceeds to step S242.

On the other hand, if the sound notification is not set in step S240, the process proceeds to step S242.
In step S242, it is checked whether or not the notification setting by display is set.
If the notification setting by display is set, the process proceeds to step S243 to activate the display notification process, and then proceeds to step S244. The display notification process may be performed by the display unit 211 for a predetermined time.
On the other hand, in step S242, when “display” is set to 0 as in the normal reading setting information (1) of FIG. 2, no notification is made by display, and the process proceeds to step S244.

In step S244, it is checked whether or not the notification setting by vibration is set.
If the notification setting by vibration is set, the process proceeds to step S245 to start the vibration notification process, and then proceeds to step S246. On the other hand, when the notification setting by vibration is not set in step S244, the process proceeds to step S246.

In step S246, it is checked whether or not the notification setting by irradiation is set.
When the report setting by irradiation is set as in the report type information 222 of FIG. 2, the process proceeds to step S247 to start the irradiation report process (FIG. 17), and then proceeds to step S248.
The irradiation notification process is a process for displaying the reading result on the barcode reading surface as shown in FIGS. 3, 5, and 6 to 13. One embodiment thereof will be described later with reference to the flowchart of FIG.

On the other hand, if the notification setting by irradiation is not set in step S246, the process proceeds to step S248. In step S248, the reading result (success or failure) 225 is transmitted to the host device.
If the barcode is successfully read, the read data 226 is also transmitted to the host device. Thereafter, the process returns to step S232.

As described above, when the process branches to step S235, it is checked in step S235 whether or not an instruction to stop the barcode reading process is given from the main process.
If there is a cancel instruction, the process proceeds to step S236, and if not, the process returns to step S232.
In step S236, the output of the reading light from the light emitting unit 207 of the reading control unit 206 is stopped.
This completes the barcode reading operation.
Thereafter, the process returns to step S231.

FIG. 17 shows a flowchart of an embodiment of the irradiation report processing of the barcode reader according to the present invention.
The notification process by irradiation here uses the configuration of one embodiment shown in FIG.
In step S271, a stop instruction is given to the barcode reader reading processing program.
Accordingly, even when the reading process in FIG. 16 is being activated and the reading light is being output, the output of the reading light is stopped in steps S235 and S236.

In step S272, the reading result 225 is read from the storage unit 220.
In step S273, it is checked whether the read result 225 read is “success” or “failure”.
If the read result is “success”, the process proceeds to step S274, and the irradiation position of the light source is set to the irradiation position at the time of success in FIG.
That is, the electromagnet of the irradiation position designation unit 502 in FIG. 6 is deenergized, and the position of the laser diode 501 (light source) is moved to the successful irradiation position.

On the other hand, if the read result is “failure”, the process proceeds to step S275, and the irradiation position of the light source is set to the irradiation position at the time of error in FIG.
In this case, the electromagnet of the irradiation position designation unit 502 is energized to operate the spring, and the position of the laser diode 501 is moved to the error irradiation position.

In step S276, the motor 504 that rotates the rotating body 503 in FIG. 6 is rotated at a predetermined speed.
In step S277, the laser diode 501 is turned on, and the emitted light is emitted in the direction of the rotating body 503.
This emitted light is reflected by the mirror on the surface of the rotator, but when the rotator rotates at a constant speed, the traveling direction of the reflected light slightly changes due to the uneven part of the mirror, and the reading port of the barcode reader 303 is output. Each time the rotating body makes one revolution, the direction of the reflected light is changed so that a character (for example, a character “OK”) as a reading result is displayed on the barcode reading surface.
At a certain moment, only one character of the read result character is displayed on the bar code reading surface, but by rotating the rotating body at high speed, the entire character of the read result is displayed on the bar code reading surface by human eyes. Appears to be displayed.

In step S278, it is confirmed whether or not a time (for example, 200 msec) corresponding to the irradiation time information 224 stored in the storage unit 220 has elapsed since the laser diode was turned on.
If it is confirmed that this time has elapsed, the process proceeds to step S279, and the laser diode is turned off. That is, the output of the reading result output light is stopped, and the display of the reading result is ended.
In step S280, the rotation of the motor 504 that has rotated the rotating body 503 is stopped.
In step S281, an activation instruction is given to the barcode reader reading processing program in order to enable the next barcode reading processing.
Thereby, in the reading process program of FIG. 16, the barcode reading process is started again in steps S231 and S232.

The above is one embodiment of the irradiation notification process that is a feature of the present invention, but is not limited to this.
In the case of having the configuration of another embodiment shown in FIGS. 7 to 13, in principle, the processes in steps S271, S272, S273, S277 to S279, and S281 are executed in the same manner, but the other processes are performed in the same manner. Processing corresponding to the configuration is executed.
