It is assumed that the handy terminal 1 and the barcode 30 in FIG. 1 are in a relative positional relationship that is a base point angle as a reference inclination angle. It is best that the handy terminal 1 performs bar code reading with the base point angle. That is, the base point angle is an inclination angle at which reading failure and misreading are minimized when barcode reading is performed.

In the state of the base point angle, as shown in FIG. 3, the axis e of the handy terminal 1 and the barcode 3

Referring to FIG. 7, a state where the handy terminal 1 (case 2) is tilted from the base point angle (X, Y, Z) will be considered. The tilt angles around the axes c, d, e in the handy terminal 1 tilted by a predetermined angle from the base point angle (X, Y, Z) are represented as device angles (X ′, Y ′, Z ′). The device angles (X ′, Y ′, Z ′) are: X ′ = X + Xmove, Y ′ = Y + Ymove, Z ′ = Z +

Next, processing executed in the handy terminal 1 will be described with reference to FIGS. 8 and 9. FIG. 8 shows the scan teaching process. FIG. 9 shows the first scan execution process.

With reference to FIG. 8, the scan teaching process executed in the handy terminal 1 will be described. The scan teaching process is a process for teaching the user the posture for reading the barcode on the handy terminal 1 and giving a warning when the difference between the base point angle and the apparatus angle is tilted larger than the limit angle. In advance, it is assumed that the handy terminal 1 is held by the user and is in a base angle posture. In addition, it is assumed that the scan teaching mode for performing the scan teaching according to the input from the user via the operation unit 12 is set. In the scan execution mode for performing normal scan execution, the process ends when the barcode is successfully read (decoded). However, in the scan teaching mode, the process is continued even if the barcode is successfully read (decoded).

Then, in the handy terminal 1, for example, it is read from the ROM 15 and triggered by the reception of the input of the trigger key 12 </ b> A from the user as a trigger.
The scan teaching process is executed in cooperation with the scan teaching program 151 expanded to 3 and the CPU 11.

First, barcode scanning by the scanner unit 16 is started (step S11). In step S11, a series of repetitive operations of light emission in the scanner unit 16, shaking the laser light to the left and right, light reception, amplification of electric signals, and binarization are started. User trigger key 12A
It is assumed that scan teaching is performed while pressing is continued.

Then, triaxial acceleration data is acquired from the acceleration sensor 19, and the base point angle (X, Y, Z) of the handy terminal 1 (case 2) is calculated and acquired according to the acceleration data and stored in the RAM 13. (Step S12). Then, the trigger key 12A is released (
It is determined whether or not it has been pressed (step S13).

When the trigger key 12A is released (step S13; YES), the scan teaching process ends. If the trigger key 12A is not released (step S13; NO), the binarized data is acquired from the scanner unit 16, and decoding is executed using the binarized data (step S14). Then, triaxial acceleration data is acquired from the acceleration sensor 19, and according to the acceleration data, the device angle (X ′, Y ′, Z ′) of the handy terminal 1 (case 2) is obtained.
) Is calculated and acquired and stored in the RAM 13 (step S15).

Then, the limit angle Xmax is read from the flash memory 17, and steps S12, S
It is determined whether or not | X−X ′ |> Xmax by using X and X ′ acquired in 15 (
Step S16). If | X′−X |> Xmax is not satisfied (step S16; NO), the difference between the pitch angle and the base point angle does not exceed the limit angle Xmax, and the flash memory 17
Then, the limit angle Ymax is read out, and it is determined whether or not | Y′−Y |> Ymax by using Y and Y ′ acquired in steps S12 and S15 (step S17). | Y'-Y |
If not> Ymax (step S17; NO), the difference between the skew angle and the base point angle does not exceed the limit angle Ymax, the limit angle Zmax is read from the flash memory 17, and the Z obtained in steps S12 and S15 is obtained. , Z ′, it is determined whether or not | Z′−Z |> Zmax (step S18).

If | Z′−Z |> Zmax is not satisfied (step S18; NO), whether the difference from the base point angle with respect to the tilt angle does not exceed the limit angle Zmax, is the decoding executed in step S14 successful (OK)? It is determined whether or not (step S19). If decoding fails (
Step S19; NO), the process proceeds to step S13. When the decoding is successful (step S19; YES), the barcode reading result corresponding to the successful decoding is displayed on the display unit 14.
Is displayed in blue (step S20), and the process proceeds to step S13. It is assumed that the blue color indicates a successful decoding when the handy terminal 1 (case) has a normal inclination. Further, the blue color is a display color of the message on the display unit 14 or a backlight color.

If | X′−X |> Xmax (step S16; YES), the pitch angle difference from the base point angle exceeds the limit angle Xmax, and an abnormal inclination detection sound is output by the buzzer 20 (step S21). . This abnormal tilt detection sound is sent to the handy terminal 1 (case 2)
It is a sound indicating that the inclination of exceeds the limit angle. If | Y′−Y |> Ymax (step S17; YES), the difference between the skew angle and the base point angle exceeds the limit angle Zmax, and the process proceeds to step S21. When | Z′−Z |> Zmax (step S1)
8; YES), the difference between the tilt angle and the base point angle exceeds the limit angle Zmax, and the process proceeds to step S21. The abnormal inclination detection sound may be a common sound with an abnormality of the pitch angle X ′, the skew angle Y ′, and the tilt angle Z ′, and the pitch angle X ′ is used to notify which angle is abnormal.
The sound may be different from each other due to abnormal skew angle Y ′ and tilt angle Z ′.

Then, it is determined whether or not the decoding executed in step S14 is successful (OK) (step S22). When decoding fails (step S22; NO), step S22
13 is transferred. When decoding is successful (step S22; YES), the barcode reading result corresponding to the successful decoding is displayed in red on the display unit 14 (step S23).
The process proceeds to step S13. It is assumed that this red color is a color indicating successful decoding when the handy terminal 1 (case) has an abnormal inclination. The red color is a message display color or a backlight color of the display unit 14.

Next, with reference to FIG. 9, the first scan execution process executed in the handy terminal 1 will be described. The first scan execution process is a process of actually executing barcode reading after the user is appropriately instructed by the scan teaching process. It is assumed that the handy terminal 1 is previously held by the user and set to the scan execution mode in accordance with an input from the user via the operation unit 12.

Then, in the handy terminal 1, for example, it is read from the ROM 15 and triggered by the reception of the input of the trigger key 12 </ b> A from the user as a trigger.
The first scan teaching process is executed in cooperation with the CPU 11 and the first scan execution program 152 developed in FIG.

First, barcode scanning by the scanner unit 16 is started (step S31). It is assumed that the user keeps pressing the trigger key 12A during the scan execution. Then, it is determined whether or not the trigger key 12A has been released (not pressed) (step S32).

When the trigger key 12A is released (step S32; YES), the first scan execution process ends. If the trigger key 12A is not released (step S32; NO), the binarized data is acquired from the scanner unit 16, and decoding is executed using the binarized data (step S33). Then, it is determined whether or not the decoding executed in step S33 is successful (OK) (step S34). When decoding fails (step S34)
NO), the process proceeds to step S32.

When the decoding is successful (step S34; YES), the buzzer 20 outputs a normal completion notification sound (step S35). This normal completion notification sound is a sound indicating that decoding has been completed successfully. Then, the barcode reading result corresponding to the successful decoding is displayed in blue on the display unit 14 (step S36), and the process proceeds to step S13.

As described above, according to the present embodiment, the handy terminal 1 scans and decodes the symbol by the scanner unit 16 and provides the base point angle (X, Y, Z) suitable for barcode reading at the time of scanning teaching. The apparatus angle (X ′, Y ′, Z ′) of the own apparatus is calculated using the acceleration data detected and detected by the acceleration sensor 19, and the base point angle (X, Y, Z) and the apparatus angle (X ′, It is determined whether or not the difference from Y ′, Z ′) exceeds the limit angle (Xmax, Ymax, Zmax). And the handy terminal 1 has the above difference as the limit angle (Xmax,
If it exceeds Ymax, Zmax), the buzzer 20 and the display unit 14 output that the limit angle (Xmax, Ymax, Zmax) has been exceeded. For this reason, the user can set the limit angle (Xmax,
(Ymax, Zmax) can be confirmed, the user can move the handy terminal 1 to read the barcode within the limit angle, and the barcode reading accuracy can be improved.

Further, at the time of abnormal inclination, the buzzer 20 outputs an abnormal inclination detection sound different from the normal completion notification sound at the normal time, and the reading result is displayed on the display unit 14 in red different from the normal blue display. For this reason, it can be confirmed through visual and auditory sense that the user exceeds the limit angle (Xmax, Ymax, Zmax).

The handy terminal 1 calculates and sets the base point angle using the acceleration data detected by the acceleration sensor 19. For this reason, the user can set an arbitrary base point angle. For example, unlike the barcodes of the arrangement described with reference to FIGS. 3 to 5, the base point angle can be easily set to a barcode having an arrangement whose longitudinal direction is not parallel to the horizontal plane.

In addition, when the difference exceeds the limit angle (Xmax, Ymax, Zmax) and the decoding is successful, the handy terminal 1 displays that the difference exceeds the limit angle and the decoding is successful together with a reading result. 14 is displayed in red. For this reason, when the difference exceeds the limit angle and decoding is successful, the user can surely confirm visually that there is a high possibility that the barcode is misread.

(Modification)
A modification of the above embodiment will be described with reference to FIGS. FIG. 10 shows the base point angle input process. FIG. 11 shows the second scan execution process.

In the embodiment described above, the user is notified that the difference between the base point angle of the handy terminal 1 and the device angle has exceeded the limit angle during scan teaching. On the other hand, this modification is configured to notify the user that the difference between the base point angle of the handy terminal 1 and the device angle has exceeded the limit angle at the time of scanning.

The apparatus configuration of this modification is a configuration using the handy terminal 1 as in the above embodiment. However, it is assumed that the ROM 15 stores a reference angle input program and a second scan execution program, which will be described later, in place of the scan teaching program 151 and the first scan execution program 152. Also, it is assumed that the various keys 12B include a base point angle input key that is a trigger key for base point angle input.

Next, the operation of the handy terminal 1 in this modification will be described. First, with reference to FIG. 10, the base point angle input process executed in the handy terminal 1 will be described. In the above embodiment, since the base point angle (X, Y, Z) is used only temporarily, it is acquired during execution of the scan teaching process and stored in the RAM 13. On the other hand, in this modification, since the base point angle once input is repeatedly used, the base point angle input process and the scan execution process are divided into separate processes. The base point angle input process of the present modification is a process in which the user inputs and sets the base point angle used for the scan execution before the scan execution.

The handy terminal 1 is held in advance by the user, and the handy terminal 1 is
Is a posture (inclination) desired to be a desired base point angle. Then, in the handy terminal 1, for example, when a pressing input of the base point angle input key of the various keys 12 </ b> B from the user is accepted, the base point angle input program read from the ROM 15 and appropriately expanded in the RAM 13 and the CPU 11 are triggered. The base point angle input process is executed in cooperation with.

First, triaxial acceleration data is acquired from the acceleration sensor 19, and the base point angle (X, Y, Z) of the handy terminal 1 (case 2) is calculated and acquired according to the acceleration data, and is stored in the flash memory 17. This is stored (step S41), and the base point angle input process ends.

Next, with reference to FIG. 11, the second scan execution process executed in the handy terminal 1 will be described. The second scan execution process is a process of notifying the user that the difference between the base point angle of the handy terminal 1 and the device angle has exceeded the limit angle and actually executing the barcode reading. It is assumed that the handy terminal 1 is previously held by the user and set to the scan execution mode in accordance with an input from the user via the operation unit 12.

Then, in the handy terminal 1, for example, it is read from the ROM 15 and triggered by the reception of the input of the trigger key 12 </ b> A from the user as a trigger.
The first scan execution process is executed in cooperation with the CPU 11 and the second scan execution program developed in FIG.

First, barcode scanning by the scanner unit 16 is started (step S51). It is assumed that the user keeps pressing the trigger key 12A during the scan execution. Then, the base point angle (X, Y, Z) of the handy terminal 1 (case 2) stored in the flash memory 17 stored in the base point angle input process is read and acquired (step S52).
.

Steps S53 to S60 are sequentially performed in steps S13 to S2 of the scan teaching process.
Same as 0. After execution of step S60, the buzzer 20 outputs a normal completion notification sound (step S61), and the second scan execution process ends. Steps S62 to S64 are
These are the same as steps S21 to S23 of the scan teaching process, respectively.

As described above, according to the present modification, the user can confirm that the user exceeds the limit angle (Xmax, Ymax, Zmax) when executing the scan, as in the above embodiment. The barcode can be read within the limit angle by moving, and the barcode reading accuracy can be improved.

In the above description, R is used as a computer-readable medium for the program according to the present invention.
Although the example using OM15 was disclosed, it is not limited to this example.
As other computer-readable media, a non-volatile memory such as a flash memory 17 and a portable recording medium such as a CD-ROM can be applied.
A carrier wave is also applied to the present invention as a medium for providing program data according to the present invention via a communication line.

The description in the above embodiment is an example of the symbol reading apparatus and the program according to the present invention, and the present invention is not limited to this.

For example, the above embodiment and modifications may be combined as appropriate. Moreover, in the said embodiment and modification, the abnormal inclination detection sound is output from the buzzer 20 as a notification part at the time of the abnormal inclination when the difference of the base point angle of the handy terminal 1 (case 2) and the device angle exceeds the limit angle. When the decoding is successfully completed without exceeding the limit angle, the normal completion notification sound is output from the buzzer 20, but the present invention is not limited to this. For example, the display by the display unit 14 as a notification unit, the lighting by the LED 21 as a notification unit, the manner of blinking, the lighting color, etc. are changed to notify the user of abnormal inclination detection or normal completion of decoding at normal inclination. It is good also as composition to do.
