Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hand-held data collection device. More specifically, the present invention relates to the quality of a barcode reading speed of a hand-held data collection device provided with barcode reading means and key input means. Regarding what can be confirmed.

[Prior art] With the development of high-density mounting technology, the use of barcodes has been progressing, and a barcode has been connected to a handy terminal, and a handheld terminal and a barcode reader have been connected by a cable. Some hand-held data collection devices, such as a so-called hand-held terminal integrated with a bar code reader, in which bar code reading means and key input means are integrated, have been announced. To use the bar code reader, the operator holds the bar code reader portion with his / her hand, reads the bar code attached to the product or the like, and directly inputs the quantity or the like with the other hand.

[Problem to be Solved by the Invention] By the way, since the proficiency varies from person to person, if an unskilled operator moves the barcode with a barcode reader to perform reading, the reading speed may be slow, On the other hand, even if an error occurs due to an early occurrence, it cannot be determined whether the movement speed of the barcode reader is slow or fast, and the operation converges within a range where no error occurs due to repetition by the operator's own judgment. However, information is only given to the operator as a result of whether or not the moving speed is within an appropriate range. Therefore, if the repetition frequency of the barcode reading is low, the memory of the operator is weakened, and it is troublesome to find an appropriate speed.

[Means for Solving the Problems] A barcode reader unit in which barcode reading means is arranged, a hand-held data collector in which key input means is arranged,
A central processing unit that processes data read by a barcode reader unit in which the barcode reading unit is arranged, and a hand-held data collection device that includes a ROM in which time data for determining whether the barcode reading time is fast or slow is input in advance; An apparatus for digitally exchanging a difference in reflectance of light emitted from the barcode reader unit, comparing the duration of the digitally converted data with time data previously input to the ROM, and reading the data. The present invention proposes a hand-held data collection device that displays data corresponding to the data.

[Operation] In the handheld data collection device of the present invention, the barcode reading speed is calculated, and the result is optically displayed when the state is too slow, too fast, or appropriate.
A buzzer sounds to confirm the barcode reading speed.

[Embodiment] Details of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, reference numeral 1 denotes a handy terminal as one embodiment of the present invention, which is connected to a reader unit 2 of bar code reading means for reading a bar code 3 by a cable 4. A light emitting element and a light emitting element (not shown) are built in the reader unit 2, and light emitted from the light emitting element irradiates the bar code 3 via a lens (not shown), and the reflected light thereof is a lens. Through the light receiving element. Handy terminal 1
Is a liquid crystal display unit 5, a printer unit 6, and an input unit 7. In the first embodiment, a buzzer 8 and a light-emitting diode display 9 are arranged around the display unit 5, in the figure, above the liquid crystal display unit 5. Have been.

Next, the operation will be described with reference to the block diagram of the handy terminal 1 in FIG. Reference numeral 10 denotes an integrated circuit central processing unit (CPU), which is a read-only memory 11 (ROM) or a random access memory 12 (RAM).
And executes a predetermined program stored in. Reference numeral 13 denotes an input / output port used for exchanging data with a host computer (not shown). The buzzer 8 emits a notification sound to the operator in accordance with the execution of the program. The light emitting diode (LED) 9 is used as one means for displaying the moving speed range of the reader unit 2 of the bar code reader.

Here, the actual operation will be described. The reader unit 2 of the bar code reader connected to the handy terminal 1
As a result, when the surface of the bar code 3 slides, light emitted from the lens portion at the tip of the bar code reader is
Will move on the striped bar code, and the intensity of light reflection will be incident via the bar code reader tip lens part due to the difference in reflectance, and will be converted into the intensity of the electric signal,
While monitoring the time during which the digital processing is performed and "1" or "0" is maintained, respectively, the data is loaded into the RAM 12, and it is previously determined whether the maintained time is smaller than a predetermined time, within a range, or larger than the ROM 11, ROM. The value recognized by ROM12 and CPU10
And outputs the result to three types of meaningful LEDs 9.

In addition, as this output means, in the case of a liquid crystal, "Hayai" and "Osoi" are displayed by characters, and when the buzzer 8 is used, three kinds of meaningful frequencies are used when the frequency is slow, within a range, and when the speed is fast. By sounding, the operator can be informed of the moving speed of the barcode reader.

[Effects of the Invention] As described above, according to the present invention, the time required to reach the optimization of the movement speed of the barcode reader is displayed by displaying the degree of the movement speed of the barcode reader or making the operator recognize the sound by voice. Can be reduced.
