Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input device for a data processing device such as an electronic register or a POS system.

[Prior Art] Conventionally, in a hand scanner such as a manual scanning barcode league installed in an electronic register, etc., it is possible to read barcodes, etc. while moving freely away from the installation location of the electronic register body, etc. A hand scanner for remote control is known that has its own key input section, display section, and power source (battery) separate from the main body in order to perform remote input operations such as inputting data such as the number of objects.

This hand scanner for remote control has a key input section on each of the four parts to prevent you from touching the key input section when you hold it in one hand and scan, and various data are displayed on the same surface as this key input section. A display section is provided to display the information.

[Problem M to be solved by the invention] For this reason, normally, barcodes, etc. are read with a hand scanner held in the right hand, and the read data is displayed on the display. To input data on the input section, the keys must be exposed and operated, so the hand scanner must be held in the left hand after each scan, which slows down the input speed and places a heavy burden on the operator. .

Furthermore, when reading a bar code or the like, the key input section is located under the palm of the hand, so there is a risk that the key may be pressed with the palm of the hand, resulting in erroneous input.

An object of the present invention is to provide an input device that does not reduce the input speed, reduces the burden on the operator, and prevents erroneous input.

[Means to solve the problem] The means of this invention are as follows.

The reading means a photoelectrically converts the reflected light of the light irradiated onto the characters using a two-dimensional photodiode, a C0D (charge-coupled device) array, etc., and analyzes electrical character pattern data as a result of the conversion. The data is read by performing character recognition, etc.

The first display means is constituted by, for example, a liquid crystal display means, is disposed at a position visible during reading scanning by the reading means a, and displays the data read by the reading means a.

The key input means 6 inputs predetermined data assigned to each key.

The second display means d is, for example, a liquid crystal display 2.
It is arranged in a position visible from the same viewing angle as the key input means C, for example, on the same plane, and displays data input from the key input means C.

[Work] The operation of the means of this invention is as follows.

When data is read by the reading means a, the read data is immediately displayed on the first display means. This first display means performs a reading operation (scanning) by the reading means a.
It is placed in a position where it can be seen while it is being performed. Further, when data is input by the key input means C, the key input data is immediately displayed on the second display means d. This second display means d is arranged at a position that can be seen from the same viewing angle as the key input means.

Therefore, there is no need to change the hand of the key input device in order to view the key input data.

Since it is only necessary to flip the input device, reading scanning and key input operations can be performed continuously.

It is possible to confirm the presence or absence of key input errors, thereby preventing a decrease in input speed and reducing the burden on the operator.

Moreover, since the key input section is located on the back side of the input device during reading scanning, there is no possibility of erroneous input.

Note that it is natural that the data from the reading means a and the key input means C is transmitted to the main body of the data processing device such as the main body of an electronic register (not shown), but the transmission method may be either wired or wireless. There may be.

Next, the operation of the first embodiment will be explained with reference to FIG.

Normally, in order to display input data from the key input unit 202, the display controller 201B of the rear display unit 201
A volt signal is input to the volt (HLT) terminal of the display controller 201B via the flip-flop 210.
By halting , the rear display section 201 is turned off. At this time, the other output signal of the flip-flop 210 is transmitted to the display controller 203B of the front display section 203.
Since it is input to the volt terminal of the flip-flop 21
According to the flip-flop function of 0, the front display section 2
03 is turned on (step Sl in FIG. 5).

Next, the key controller 202B is accessed (Step S2), and it is determined whether or not there is a key operation on the keyboard 202A or the display switching key switch 211 (Step S2).
3) As a result, if there is no key operation, step S2
By returning to.

It waits for a key operation to be performed. On the other hand, if there is a key operation, the process advances to step S4 and it is determined whether or not the 1-display switching key switch 211 has been operated. As a result, when the display switching key switch 211 is operated, the front display section 203 is operated under the control of the flip-flop 210.
is turned off and the rear display section 201 is turned on to switch the display (step S5). Then, while resetting the soft timer, the recognition controller 204A is enabled under the control of the flip-flop 210. , the light emitting diode 204C is not turned on until the light emitting diode 204C is turned on (step S6), that is, the 1 display switching key switch 211 is operated.

Power consumption is saved and the life of the battery 205 is extended. This reduces the number of times batteries need to be replaced and reduces maintenance costs.

Next, the recognition controller 204A is accessed (step S7), and it is determined whether the barcode has been recognized or whether a time has elapsed (step S8).
), as a result, if the barcode is not recognized and the time has not exceeded, the process proceeds to step S9; otherwise, the process proceeds to step SlO. In step S9,
The soft timer is updated, and then the process returns to step S7. In step 510, it is determined whether a timeout has occurred. As a result, if the time has not exceeded and the barcode has been recognized, predetermined barcode input processing is performed (step 5ll). After that, in order to display the recognized barcode on the rear display section 201, control (step 312), then by disabling recognition controller 204A.
turning off the light emitting diode 204C step 513);
Return to step S2. On the other hand, if the time has expired, the process immediately proceeds to step 313 to turn off one light emitting diode 204C.

In other words, when a barcode is not recognized within a certain period of time, and every time a barcode is recognized and input processing and rear display processing related to the recognized barcode are performed,
Power consumption is further reduced by turning off the light emitting diode 204C.

If it is determined in step S4 that the operation is not the display switching key switch 211 but the key operation on the keyboard 202A, the process advances to step S14. If the front display unit 203 is turned off, the rear display! 201 is turned off and the front display section 203 is turned on, the display is switched, and predetermined key processing such as sign-in processing corresponding to the operated key is performed (step 315), and the contents of the key are displayed on the front panel. Performing one-curve display control to display on the display unit 203 (step 316),
Return to step S2.

In this way, the rear display section 201 and the front display section 203 are never turned on at the same time, and when one is on, the other is always turned off, so power consumption can be saved. Can be done.

Next, the operation of the second embodiment will be explained with reference to FIG.

First, in step S2', it is determined whether or not the user is currently signed out.
l) If the user is signing out, it is further determined whether the touch sensor 21 is on (step 322).
As a result, if the touch sensor 21 is off, the process returns to step 321, and if the touch sensor 21 is on, it means that the handy barcode reader 20 is being held, so only the front display section 203 is turned on. (Step 52
3) Next, it is determined whether or not a password corresponding to the person in charge registered in advance in the input side RAM 208 has been input, that is, whether or not a sign-in input has been input (step 524). As a result,
If there is a sign-in input, a sign-in process is performed (step 525), and the process returns to step S21. If there is no sign-in input, the process directly returns to step 321.

While signing out in this manner, the front display section 203 is turned on by grasping the handy barcode reader 20, and then, by performing a sign-in input, the sign-in process is performed and data input is possible.

If it is determined in step 321 that sign-in is in progress, the process proceeds to step 52B, where it is determined whether the touch sensor 21 is on. As a result, touch sensor 2
If 1 is on, the PIN code for signing out,
If there is no input of sign-out data (password), it is further determined whether the proximity sensor 22 is on (step 52).
8) As a result, if the proximity sensor 22 is on, the handy barcode reader 2 is activated to scan the barcode.
0 means that the barcode has been brought close to the wrapping paper or the like printed on it, so the reader 204 is turned on (step 329), and the process proceeds to step 330, where it is determined whether or not a barcode has been input. to decide. If no barcode has been input, the process returns to step 321; if a barcode has been input, only the rear display section 201 is turned on (step 530), and the contents of the input barcode are (barcode number) on the rear display section 20
1, and after a certain period of time, the back display section 201 is turned off (step 531). Through this off process, both the back display section 201 and the front display section 203 are turned off. In this way, by turning off the rear display section 201 after a certain period of time, for example, one product has been purchased, the barcode of that product is scanned, and then the store Q (person in charge) can purchase another product. Wasteful power consumption can be avoided while explaining the product to the customer.Next, predetermined processing according to the input barcode is performed (Step 2 533), and the process returns to Step 521. .

On the other hand, when it is determined in step 328 that the proximity sensor 22 is off, the process proceeds to step 334, where only the front display section 203 is turned on. Then, it is determined whether or not a key input other than the password for signing out has been made (step 535); if the key input has not been made, the process returns to step S21;
When the above key input is made, a predetermined process according to the key input is performed (step 536), and step 3
Return to 21.

If it is determined in step 327 that a password for signing out has been entered, an upcoming sign-out process is performed (step 337).

The reading unit 204 is turned off (step 538), and the process returns to step S21.

Further, when it is determined in step S26 that the touch sensor 21 is off, the process advances to step S39, and it is determined whether registration is in progress, that is, whether sign-in processing is being performed. do. As a result, if the registration is not in progress, the process returns to step S21; if the registration is in progress, the process returns to step S21.

It is determined whether the off state of the touch sensor 21 continues for longer than a certain period of time (step 540), and as a result,
If not, return to step 321,
If it continues, perform signature lock processing (step 3).
41), and displays the name of the person in charge corresponding to the currently signed-in PIN on the front display section 203 (step 542), and sounds a buzzer for a certain period of time (step 3).
43), return to step 521.

With such a sign lock process, for example, if the person in charge of the current sign-in leaves the Handy Barcode League 20 unattended and goes looking for a product, another person in charge can It is possible to eliminate the problem of destroying data corresponding to the current sign-in by operating the barcode league 20.

In this way, in the second embodiment, 1
If the data input operation is performed as usual without consciously operating the display switching key switch 211, the display switching will be performed automatically.

It becomes more user-friendly.
