Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a data transmission wireless device, and more particularly to a data transmission wireless device whose operation and configuration are suitable for reducing the burden on the user.

[0002]

[Prior art]

 As a conventional data transmission radio device, for example, one having a shape as shown in FIGS. 7 and 8 has been provided.

In the figure, 2 is a display unit, 3 is a keyboard, 21 is a handy terminal, and 22 is a shoulder belt.

In recent years, handy terminal devices for wireless data transmission have become popular in restaurants, warehouses, factories, etc., but the shape and structure of the handy terminal device are used for displaying the data and the keyboard 3 for confirmation. The handheld terminal (Fig. 7), which is equipped with a display unit 2 and has a wireless unit and a built-in antenna inside the case (Fig. 7), and a shoulder belt 22 provided on the case to hang it on the operator's shoulder. There was a portable type (Fig. 8).

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional data transmission wireless device, as shown in FIGS. 7 and 8, the shape is a handy type that can be held with one hand when operating the keyboard, and a wireless unit is also incorporated. Since it was an integrated type, when entering data with the keyboard, you must always hold it with one hand or place it on a table etc., and also when carrying it, you must put it in your pocket or bag. Even if a shoulder belt is attached, it is physically burdensome for the worker to always wear the belt on the shoulder, and in both cases, the workability and portability for the worker are poor. there were.

The present invention has been made in view of the above points, and an object thereof is to solve the conventional drawbacks and provide a data transmission wireless device with good workability without burdening an operator. It is in.

[0007]

[Means for Solving the Problems]

 The data transmission radio device of the present invention is a data transmission system including a control unit configured by a keyboard for inputting data and a data display unit, and a radio unit for transmitting data to a base station. The control unit and the radio unit are connected separately by a radio having a frequency different from the frequency transmitted to the base station.

[0008]

[Action]

 According to this invention, in a data transmission system including a control unit configured by a keyboard for inputting data and a data display unit and a wireless unit for transmitting data to a base station, the control unit and the wireless unit are separated from each other. Since the control unit and the wireless unit are connected separately by a radio having a frequency different from the frequency transmitted to the base station, the control unit and the wireless unit can be easily carried by the user, for example, The control unit is attached to the wrist like a clock, and the radio unit is attached separately in the pocket of clothes, which can improve the usability of operating the keyboard while holding it by hand. Like

【Example】

 An embodiment of a data transmission radio device according to the present invention will be described with reference to FIGS.

FIG. 1 is a configuration block diagram of a data transmission system showing an embodiment of the present invention, FIG. 2 is a front view showing a state in which a control unit is attached to an operator's arm, and FIG. 3 is a control unit attached to the operator's arm. FIG. 4 is a side view showing a state in which the wireless unit is attached to an arm, FIG. 4 is a diagram showing a state in which a wireless unit is stored in an operator's pocket, and FIG. 5 is a diagram showing an example in which an external antenna also serving as a name tag is attached to the wireless unit. FIG. 6 is a view showing a state in which a wireless unit with an external antenna of another embodiment is attached to a waist belt of an operator.

In the figure, 1 is a control unit, 2 is a display unit, 3 is a keyboard, 4 is a fixing band, 5 is a wireless unit, 6 is a worker's arm, 7 is a worker's pocket, and 8 is data input / output. Part, 9 is a weak radio unit (A), 10 is a weak built-in antenna (A), 11 is a main radio part, 12 is a weak radio unit (B), 13 is a weak built-in antenna (B), and 14 is a main radio A built-in antenna for a part, 15 is a base station antenna, 16 is a base station, 17 is a name tag combined antenna, 18 is a name tag combined antenna connection part, 19 is a belt type antenna, and 20 is a worker's waist belt.

The configuration blocks of the data transmission system of the present invention will be described. The control unit 1 and the wireless unit 5 are separate, and the control unit 1 and the wireless unit 5 are each a weak wireless unit (A) 9, A weak radio unit (B) 12, a weak built-in antenna (A) 10, and a weak built-in antenna (B) 13 are provided, and data transmission by weak radio waves is performed between these two units. .

A data input / output unit 8 is housed in the control unit 1, and a main radio unit 11 and a built-in antenna 14 for the main radio unit are housed in the radio unit 5. The main radio unit 11 is a main radio unit. The data from the control unit 1 is transmitted to the base station 16 via the base station antenna 15 via the built-in antenna 14 for use in the base station.

That is, the radio frequency from the weak radio unit (A) 9 of the control unit 1 is different from the radio frequency from the main radio unit 11 of the radio unit 5 to the base station 16, and the radio unit 5 is a weak radio unit. (A) It has only the function of converting the radio frequency from 9 into the radio frequency from the main radio section 11 to the base station 16.

By separating the control unit 1 and the wireless unit 5 from each other as described above, the control unit 1 becomes compact, and as shown in FIG. 2 and FIG. Since the wireless unit 5 can be stored in the operator's pocket 7 as shown in FIG. 4, it is necessary to hold the unit in one hand to operate the keyboard 3. It becomes a hand-free machine, and data can be easily input, improving workability.

Further, in order to improve the transmission between the wireless unit 5 and the base station 16, the antenna is put out of the unit as shown in FIGS. 5 and 6, and in the example of FIG. The name tag combined antenna 17 that can also be used as a name tag can be stored in the operator's chest pocket, and the name tag combined antenna 17 and the wireless unit 5 are connected by the foldable name tag combined antenna connection portion 18. By doing so, it is possible to make the storage more wide.

Further, in the example shown in FIG. 6, the wireless unit 5 is attached to the waist belt 20 of the worker by using a belt hook or the like, and the belt type antenna 19 is attached to the side surface of the wireless unit 5 to attach the belt type antenna 19 to the belt type antenna 19. By fixing the waist belt 20 through the inside, the belt type antenna 19 can be lengthened and an antenna with high radiation efficiency can be obtained.

[Effect of the device]

 Since the data transmission wireless device according to the present invention is configured as described above, it has the following effects.

Since the control unit and the wireless unit are separated so that they can be worn by the worker, both hands of the worker can be opened at all times except when inputting data, and the burden on the worker can be reduced and work can be performed. Has the effect of ensuring the safety of

In addition, by separating the control unit and the wireless unit, it is possible to reduce the weight of each and reduce the physical burden even if the worker wears it for a long time.

Furthermore, since an external antenna can be easily attached to the wireless unit, it is possible to allow data transmission over a somewhat long distance even in a small system.

Moreover, since the wireless unit and the control unit are wirelessly connected to each other, the wireless unit has an excellent feature that the wireless unit can be stored in a place desired by the operator and the degree of freedom is improved.
