The operation unit 15 includes a trigger key for causing the barcode scanner 18 to perform a scanning operation, as well as cursor keys, character input keys, function keys, and the like. The operation unit 15 converts the user's input operations on these keys into operation signals and outputs them to the CPU 11. The operation unit 15 may accept input operations from the user through a touch panel placed over the screen of the display unit 16.

The display unit 16 is arranged on the front of the handy terminal 10, and is configured with an LCD (Liquid Crystal Display) or an EL (Electro Luminescence) display, and displays the results and status of various processes.

The communication unit 17 is a communication module having an antenna, a modulation/demodulation circuit, a signal processing circuit, etc., and performs communication control in accordance with a communication standard related to wireless communication using a wireless LAN. Under the control of the CPU 11, the communication unit 17 performs wireless communication with one access point that is set in advance as a communication connection target, and sends and receives data to and from the server via the access point.

The barcode scanner 18 decodes signals obtained by reading symbols such as barcodes and two-dimensional codes generated according to predetermined rules, and outputs the decoded signals to the CPU 11.

Further, the audio output unit 20 outputs sound at a frequency, length, and number of outputs according to a control signal from the CPU 11.

Next, the initial setting operation of the handy terminal 10 in the terminal management system 1 will be explained. This initial setting operation is executed when activating the plurality of handy terminals 10 constituting the terminal management system 1 from the state at the time of shipment.

FIG. 3 is a flowchart showing the flow of the initial setting operation.
In this initial setting operation, the user first selects one handy terminal 10 as the base unit 10A (step S101), and performs initial settings for this base unit 10A (step S102). In the initial settings, a predetermined setting screen is displayed on the display unit 16A, and on the setting screen, the SSID and authentication code of the access point to which the base unit 10A connects, the IP address of the server to connect to, the name of the destination folder, and the user's information are entered. Various pieces of information such as email addresses are input in order by the user. Information is input by inputting operations on the operation unit 15A. As a result, setting information related to the operation settings of the base device 10A is stored in the operation setting data 142A of the base device 10A.

Next, the setting information of the base device 10A is copied to the slave device 10B in steps S103 to S105.
That is, the user first selects one handset (step S103), causes the base device 10A to execute a two-dimensional code display process, which will be described later, and causes the slave device 10B to execute a two-dimensional code reading process, which will be described later. , copies the wireless LAN setting information of the base device 10A to the slave device 10B (step S104). Here, the wireless LAN setting information is part of the setting information stored in the operation setting data 142A of the base unit 10A, and includes, for example, information on the SSID and authentication code of the access point.

In the two-dimensional code display process by the base unit 10A, as shown in FIG. When referring to one, the two-dimensional code 30) are sequentially displayed on the display unit 16A of the base unit 10A. The two-dimensional codes 30a to 30c contain divided wireless LAN setting information of the base unit 10A. In addition, in the two-dimensional code reading process by the handset 10B, the two-dimensional codes 30a to 30c displayed on the display section 16A of the base device 10A are read one by one by the barcode scanner 18B of the handset 10B. The wireless LAN setting information of the base unit 10A is acquired from the read two-dimensional codes 30a to 30c, and is reflected (duplicated) in the operation setting data 142B of the slave unit 10B. The two-dimensional codes 30a to 30c correspond to "a plurality of symbols".

Next, the handset 10B is connected to the access point via the wireless LAN based on the copied wireless LAN setting information, and then the base device 10A and the handset 10B are connected to the wireless LAN via the access point. Then, the remaining operation settings of the base unit 10A are copied to the slave unit 10B through wireless LAN data communication (step S105). This completes the initial setting of one slave device 10B.

Next, it is determined whether or not the replication of the operation settings has been completed for all slave units 10B (step S106), and if the replication of the operation settings has not been completed for any of the slave units 10B (step S106: NO''), the process returns to step S103 and the operation settings are copied to other slave devices 10B (steps S103 to S105).
If the duplication of the operation settings has been completed for all slave units 10B (“YES” in step S106), the initial setting operation ends.

In FIG. 3, the initial setting of one handset 10B is completed in steps S103 to S105, and this operation is repeated for the number of handsets 10B. However, the present invention is not limited to this. For example, by reading the two-dimensional codes 30a to 30c, the wireless LAN setting information is first copied to all handsets 10B, and then the remaining initial settings of each handset 10B are performed by data communication via the wireless LAN. You can. For the initial settings in this case, a known method (for example, MDM (Mobile Device Management)) for performing initial settings with the same contents on a plurality of handy terminals 10 via wireless data communication can be used.

Below, the operation of the base device 10A and the slave device 10B in step S104 will be described in detail.

FIG. 4 is a diagram illustrating the contents of the two-dimensional codes 30a to 30c displayed on the base unit 10A.
The amount of information included in one two-dimensional code, that is, the maximum amount of information that can be obtained from the decoding result of one two-dimensional code, depends on the display size and resolution of the display unit 16A, and the type of two-dimensional code. , is approximately 1000 bytes in this embodiment. On the other hand, since the wireless LAN setting information 40 to be copied has an information amount exceeding 2000 bytes, it is necessary to divide it into three two-dimensional codes 30a to 30c and transmit it. Therefore, the wireless LAN setting information 40 is divided in advance into three pieces of divided setting information 40a to 40c. The wireless LAN setting information 40 may be file data in a predetermined format, or may be setting value data itself arranged in a predetermined format. The wireless LAN setting information 40 corresponds to "setting information related to the operation settings of other terminal devices" and "information for copying the operation settings of the own device to other terminal devices."

Furthermore, each of the two-dimensional codes 30a to 30c includes any one of output sound designation information 50a to 50c (designation information). Each of the output sound designation information 50a to 50c is information that designates the form of the success sound to be output to the audio output section 20B of the slave unit 10B. Hereinafter, when referring to any one of the output sound designation information 50a to 50c, it will be referred to as output sound designation information 50. The output sound specification information 50 specifies at least one of the frequency, length, and number of outputs of the sound to be output. The output sound specification information 50 is approximately 10 bytes of data. For example, when the audio output unit 20B is capable of outputting a first sound and a second sound that have different frequencies, the output sound designation information includes 2-byte data that designates the first sound, 2 bytes of data that specifies the number of seconds the sound will play, 2 bytes of data that specifies the second sound, 2 bytes of data that specifies the number of seconds that the second sound will play, and the number of times the sound will repeat. Consists of 2 bytes of data. The output sound designation information 50a to 50c differ from each other in at least one of the frequency, length, and number of outputs of the sound to be output. The output sound designation information 50a to 50c in this case corresponds to "a plurality of designation information each designating mutually different aspects of notification". However, the present invention is not limited to this, and some or all of the plurality of output sound designation information 50 may designate the same mode of notification. The output sound designation information 50a to 50c may be prepared in advance, or may be generated by the CPU 11A each time the two-dimensional code 30 is generated.

When the division setting information 40a to 40c and the output sound designation information 50a to 50c are prepared, two-dimensional codes 30a to 30c are generated from these pieces of information. That is, based on the division setting information 40a and the output sound specification information 50a, a two-dimensional code 30a is generated that can obtain binary data of the division setting information 40a and the output sound specification information 50a by decoding. Further, based on the division setting information 40b and the output sound specification information 50b, a two-dimensional code 30b that can obtain the binary data of the division setting information 40b and the output sound specification information 50b by decoding is generated. Further, based on the division setting information 40c and the output sound specification information 50c, a two-dimensional code 30c is generated that can obtain binary data of the division setting information 40c and the output sound specification information 50c by decoding. The output sound designation information 50 may appear, for example, at the end of the decoding result of the two-dimensional code 30. The two-dimensional codes 30a to 30c are generated by processing by the CPU 11A.

FIG. 5 is a diagram illustrating a two-dimensional code display operation by the base unit 10A and a two-dimensional code reading operation by the slave unit 10B.
In FIG. 5, the transition of each operation of the master device 10A and the slave device 10B is expressed in chronological order with time as the horizontal axis. FIGS. 5(a1) to (a3) show the operation of the base unit 10A when executing the above-described two-dimensional code display process. FIGS. 5(b1) to (b3) show the operation of the slave unit 10B during execution of the above-described two-dimensional code reading process.

When the two-dimensional codes 30a to 30c are generated, the first two-dimensional code 30a is displayed on the display section 16A of the base unit 10A (FIG. 5(a1)).

When the handset 10B reads this two-dimensional code 30a with the barcode scanner 18B, the division setting information 40a and output sound designation information 50a included in the two-dimensional code 30a are acquired by the handset 10B. The handset 10B outputs the success sound S1 from the audio output unit 20B in a manner according to the acquired output sound designation information 50a (that is, the frequency, length, and number of outputs designated by the output sound designation information 50a) (FIG. 5 (b1)). The operation of outputting a success sound from the audio output unit 20B of the handset 10B is one mode of notification performed in response to symbol reading.

When the base device 10A detects the success sound S1 in the manner specified by the output sound designation information 50a, the base device 10A switches the displayed image from the two-dimensional code 30a to the next two-dimensional code 30b (FIG. 5 (a2)). The detection of the success sound S1 is performed by the CPU 11A based on the electrical signal from the audio input section 19A. That is, when the electrical signal transmitted from the audio input unit 19A in response to the sound input indicates the success sound S1 of the frequency, length, and number of outputs specified by the output sound designation information 50a, the detection means The CPU 11A detects that the success sound S1 has been output from the handset 10B.

When the slave unit 10B reads the two-dimensional code 30b, the division setting information 40b and output sound designation information 50b included in the two-dimensional code 30b are acquired by the slave unit 10B. The handset 10B outputs the success sound S2 from the audio output unit 20B in the manner specified by the acquired output sound specification information 50b (FIG. 5(b2)).

When the base unit 10A detects the success sound S2 in the manner specified by the output sound specification information 50b, the base device 10A switches the displayed image from the two-dimensional code 30b to the next two-dimensional code 30c (FIG. 5 (a3)).

When the slave unit 10B reads the two-dimensional code 30c, the division setting information 40c and output sound designation information 50c included in the two-dimensional code 30c are acquired by the slave unit 10B. The handset 10B outputs the success sound S3 from the audio output unit 20B in the manner specified by the acquired output sound specification information 50c (FIG. 5(b3)).

When the master device 10A detects the success sound S3 in the manner specified by the output sound specification information 50c, it determines that reading of all the two-dimensional codes 30a to 30c is completed, and ends the two-dimensional code display process.
Furthermore, the handset 10B acquires the wireless LAN setting information 40 from the acquired division setting information 40a to 40c, reflects it in the operation setting data 142B of the handset 10B, and ends the two-dimensional code reading process.
In the above, the main device 10A switches the display of the two-dimensional code images 30a, 30b, and 30c in the order of Any one two-dimensional code 30 that has not been displayed among the dimensional code images 30a to 30c may be displayed in random order.

Next, control procedures for the two-dimensional code display process and the two-dimensional code reading process will be explained.

FIG. 6 is a flowchart showing a control procedure for two-dimensional code display processing by the CPU 11A of the base device 10A.
When the two-dimensional code display process is started, the CPU 11A divides the wireless LAN setting information 40 into divided setting information 40a to 40c, as shown in FIG. 4 (step S201). Further, the CPU 11A generates two-dimensional codes 30a to 30c each including one of the division setting information 40a to 40c and one of the output sound designation information 50a to 50c (step S202).

The CPU 11A serving as a display control means displays the first two-dimensional code 30 (two-dimensional code 30a in the example of FIG. 5) on the display section 16A (step S203).

The CPU 11A serving as a detection means determines whether or not a success sound in the manner specified by the output sound specification information 50 included in the displayed two-dimensional code 30 has been detected (step S204), and determines that no success sound has been detected. If it is determined that (“NO” in step S204), the process of step S204 is executed again.

If it is determined that a success sound has been detected ("YES" in step S204), the CPU 11A determines whether reading of all two-dimensional codes 30a to 30c has been completed (step S205). Here, the CPU 11A determines that reading of all the two-dimensional codes 30a-30c has been completed when success sounds S1-S3 corresponding to the two-dimensional codes 30a-30c have been detected.

If it is determined that the reading of one of the two-dimensional codes 30 is not completed (“NO” in step S205), the CPU 11A as a display control means changes the image to be displayed on the display unit 16A to the next two-dimensional code. The code is switched to code 30 (step S206), and the process returns to step S204.
If it is determined that all the two-dimensional codes 30a to 30c have been read (“YES” in step S205), the CPU 11A ends the two-dimensional code display process.

FIG. 7 is a flowchart showing the control procedure of the two-dimensional code reading process by the CPU 11B of the slave device 10B.

When the two-dimensional code reading process is started, the CPU 11B causes the barcode scanner 18B to read the two-dimensional code 30 displayed on the display section 16A of the base device 10A in response to an input operation from the user (step S301 ).

The CPU 11B serving as a notification control means extracts the output sound designation information 50 from the read two-dimensional code 30 (step S302), and causes the audio output unit 20B to output a success sound in the manner specified by the output sound designation information 50. (Step S303).

The CPU 11B determines whether reading of all two-dimensional codes 30a to 30c has been completed (step S304). The method for this determination is not particularly limited, but for example, the number of two-dimensional codes 30 to be read may be included in each two-dimensional code 30 and compared with the number of two-dimensional codes 30 that have already been read. be able to. If it is determined that reading of any two-dimensional code 30 is not completed (“NO” in step S304), the CPU 11B returns the process to step S301.

If it is determined that reading of all the two-dimensional codes 30a to 30c has been completed (“YES” in step S304), the CPU 11B reads the division setting information 40a to 40c of the plurality of read two-dimensional codes 30a to 30c. The wireless LAN setting information 40 is acquired and reflected in the operation setting data 142B (step S305).
When the process of step S305 ends, the CPU 11B ends the two-dimensional code reading process.

(Modified example)
In the above embodiment, the output of a success sound is exemplified as the notification from the handset 10B, but the type of notification is not limited to this. For example, the notification may be light emission. In this case, a light emitting section that emits light may be provided in place of the audio output section 20B, and a light receiving section that receives light emitted from the light emitting section of another handy terminal 10 may be provided in place of the audio input section 19A. Bye. Further, instead of the output sound specification information 50, specification information specifying the mode of light emission is included in the two-dimensional code 30. The content specified by this specification information can be at least one of the color of emitted light, the number of blinks, and the blink cycle. The handset 10B that has acquired this designation information from the two-dimensional code 30 causes its light emitting unit to emit light in a manner according to the designation information. On the other hand, when the base device 10A detects light emission in the manner specified by the designation information, the base device 10A switches the two-dimensional code 30 to be displayed on the display section 16A.
This modification may be combined with the second embodiment described later.

As described above, the handy terminal 10 (base unit 10A) as a terminal device according to the first embodiment includes the CPU 11A, and the CPU 11A displays one two-dimensional code 30 among the plurality of two-dimensional codes 30 on the display. 16A (display control means), detects a success sound from the handset 10B that is output in response to reading of one two-dimensional code 30 by the handset 10B (detection means), and detects a success sound from the handset 10B (detection means). The CPU 11A can acquire information including output sound specification information 50 that specifies the output mode of the success sound from each of the two-dimensional codes 30, and the CPU 11A can obtain the output sound specification information 50 in accordance with the output sound specification information 50 obtained from the one two-dimensional code 30. When a success sound is detected, the two-dimensional code 30 to be displayed is switched to another two-dimensional code 30 among the plurality of two-dimensional codes 30 (display control means). Thereby, by dividing the information to be transmitted and including it in each of the plurality of two-dimensional codes 30, the information to be transmitted can be acquired on the slave device 10B side. Therefore, even in a situation where the base unit 10A and the slave unit 10B are not connected for communication, large amounts of information can be easily exchanged via the two-dimensional code 30. In addition, by switching the display of the two-dimensional code 30 according to the detection of a success sound, the next two-dimensional code 30 is displayed in a timely manner and automatically according to the completion of reading the two-dimensional code 30 on the handset 10B. can be done. Therefore, information can be exchanged easily and appropriately via the two-dimensional code 30.

Further, from each of the plurality of two-dimensional codes 30, one of the plurality of output sound designation information 50 specifying mutually different output modes of the success sound can be acquired, and from each of the plurality of two-dimensional codes 30, The acquired output sound designation information 50 is different from each other. Thereby, the read two-dimensional code 30 can be specified according to the success sound. Therefore, it is possible to more reliably detect that each of the plurality of two-dimensional codes 30 has been read.

Further, the notification is a sound output. Thereby, in a situation where the base unit 10A and the slave unit 10B are not connected for communication, the slave unit 10B can notify the base unit 10A that reading of the two-dimensional code 30 has been completed in a simple manner.

Further, the output sound specification information 50 specifies at least one of the frequency, length, and number of outputs of the sound to be output. This makes it possible to specify output modes of success sounds that are easy to distinguish from each other using simple parameters.

Moreover, the notification in the above modification is light emission. Thereby, in a situation where the base unit 10A and the slave unit 10B are not connected for communication, the slave unit 10B can notify the base unit 10A that reading of the two-dimensional code 30 has been completed in a simple manner.

Further, the specification information in the above modification specifies at least one of the color of the emitted light, the number of blinks, and the blink cycle. With this, it is possible to specify light emission modes that are easily distinguishable from each other using simple parameters.

Further, from each of the plurality of two-dimensional codes 30, it is possible to obtain different parts of the setting information related to the operation settings of the handset 10B. Thereby, by acquiring the setting information in the handset 10B and reflecting it in the operation setting data 142B of the handset 10B, the operation settings of the handset 10B can be performed.

Further, the setting information is information for copying the operation settings of the own device to the slave device 10B.

(Second embodiment)
Next, a second embodiment will be described. This embodiment differs from the first embodiment in the display manner of the two-dimensional code 30 in the two-dimensional code display process. Below, differences from the first embodiment will be explained.

FIGS. 8 to 10 are diagrams illustrating a two-dimensional code display operation by the base unit 10A and a two-dimensional code reading operation by the slave unit 10B in the second embodiment.
As shown in FIG. 8(a1), in this embodiment, when the two-dimensional codes 30a to 30c are generated, the base device 10A switches the plurality of two-dimensional codes 30a to 30c and displays them one by one on the display unit 16A. Perform the display operation to display. That is, the master device 10A repeatedly displays the two-dimensional code 30a, the two-dimensional code 30b, and the two-dimensional code 30c in this order. The display switching period is not particularly limited, but may be, for example, about 1 second to several seconds.

The handset 10B reads any one of the two-dimensional codes 30a to 30c displayed in rotation, which is determined by the reading timing. That is, when the barcode scanner 18B starts a scanning operation in response to the user's input operation, it reads the two-dimensional code 30 displayed on the display unit 16A of the base device 10A. Then, the handset 10B outputs a success sound from the audio output unit 20B in the manner specified by the output sound designation information 50 included in the read two-dimensional code 30 (FIG. 8(b1)). In the example of FIG. 8(b1), the handset 10B reads the two-dimensional code 30b and outputs the success sound S2 in the form specified by the output sound specification information 50b included in the two-dimensional code 30b from the audio output unit 20B. do.

When the base device 10A detects a successful sound in a manner according to any one of the output sound designation information 50 among the plurality of output sound designation information 50a to 50c, the master device 10A outputs a second output sound designation information 50 that specifies the output sound designation information 50 that specifies the output sound designation information 50. The dimension code 30 is excluded from the display target of the above display operation (FIG. 9(a2)). In the example of FIG. 9(a2), the master unit 10A detects the success sound S2 in the manner specified by the output sound specification information 50b, and in response, displays the two-dimensional code 30b including the output sound specification information 50b. Exclude from the display target of cyclic display in action. Therefore, from now on, the base device 10A alternately switches and displays the two-dimensional codes 30a and 30c.

The handset 10B reads any one of the two-dimensional codes 30a and 30c that are alternately displayed, which is determined by the reading timing. Here, it is assumed that the two-dimensional code 30c has been read. The handset 10B outputs the success sound S3 from the audio output unit 20B in the manner specified by the output sound designation information 50c included in the two-dimensional code 30c (FIG. 9(b2)).

The base unit 10A detects the success sound S3 in the manner specified by the output sound specification information 50c, and accordingly excludes the two-dimensional code 30c including the output sound specification information 50c from the display target of the circular display in the display operation. (Figure 10(a3)). Therefore, from now on, the base device 10A displays the two-dimensional code 30a and does not switch the display.

When the handset 10B reads the two-dimensional code 30a, it outputs the success sound S1 from the audio output unit 20B in the manner specified by the output sound specification information 50c included in the two-dimensional code 30a (FIG. 10(b3)). ).

When the master device 10A detects the success sound S1, it determines that reading of all the two-dimensional codes 30a to 30c has been completed, and ends the two-dimensional code display process.
Furthermore, the handset 10B acquires the wireless LAN setting information 40 from the acquired division setting information 40a to 40c, reflects it in the operation setting data 142B of the handset 10B, and ends the two-dimensional code reading process.

Next, a control procedure for two-dimensional code display processing in the second embodiment will be described. Note that the two-dimensional code reading process in the second embodiment is the same as that in the first embodiment except for the order of the two-dimensional codes 30 to be read, so a description thereof will be omitted.

FIG. 11 is a flowchart showing a control procedure for two-dimensional code display processing according to the second embodiment. The two-dimensional code display process of the second embodiment corresponds to the two-dimensional code display process of the first embodiment (FIG. 6) in which steps S203, S204, and S206 are replaced with steps S207, S208, and S209, respectively. . Below, differences from the flowchart in FIG. 6 will be explained.

In the examples shown in FIGS. 8 to 10, the two-dimensional codes 30a to 30c are displayed cyclically when step S207 is executed for the first time.

The CPU 11A determines whether or not a success sound in a manner specified by any one of the output sound designation information 50 among the plurality of output sound designation information 50 included in the plurality of two-dimensional codes 30 that are displayed in circulation is detected. (Step S208). If it is determined that the success sound has not been detected (“NO” in step S208), the CPU 11A executes the process of step S208 again, and if it is determined that the success sound has been detected (“NO” in step S208), the CPU 11A executes the process of step S208 again. (“YES”), the process moves to step S205.

In the process of step S205, if it is determined that reading of any two-dimensional code 30 is not completed (“NO” in step S205), the CPU 11A reads the two-dimensional code 30 corresponding to the success sound detected in step S208. The dimension code 30 is excluded from the circular display target (step S209), and the process returns to step S208.
In the process of step S205, if it is determined that all the two-dimensional codes 30a to 30c have been read ("YES" in step S205), the CPU 11A ends the two-dimensional code display process.
