Abstract

PURPOSE:To prevent malfunction due to a key operation by providing a gate circuit which is opened after the completion of processing in a remote control data transfer processing part to input a read command signal to a read processing part. CONSTITUTION:When bar code read processing is performed in a read processing circuit 14 by the first operation of a first key SW1, a switch constituting the gate circuit cuts off signal lines (a) and (b) from each other by the reset signal from a processing signal terminal t5, and a switch 16 connects signal lines (e) and (f) to each other. Therefore, since the transfer command signal from a control part 20 is detected by a transfer start judging circuit 17, the read processing is performed in a transfer processing circuit 18 by the first operation of the first key SW1, and the data signal stored in the read processing circuit 14 is taken in. A remote control data signal generated based on this data signal is transferred to a host device. Thus, the data signal is not erased though the key is erroneously operated.

The remote control data signal from the output terminal of the transfer processing circuit 18 is configured to be input to a host device (not shown).

Next, the operation of the conventional barcode remote control device having the above configuration will be explained.

When the barcode is read by the barcode remote control device and the remote control data signal obtained by encoding the obtained data signal is transferred to the host device, the signal line 2 is transmitted from the processed signal terminal t8 of the transfer processing circuit 18. A reset signal is input to the controller section 20.

By this reset signal, the read start input circuit I and the transfer start input circuit 5 are activated, and the first

In this state, when the first key SWI is operated to input a reading command signal to the control unit 20, the fifth
In step S1 of the flowchart shown in the figure, the reading start input circuit 1 memorizes that the first key SW1 has been operated, and the reading command signal passes through the signal line a, the switch 12, and the signal line S to determine the start of reading. It is input to the circuit 13.

Next, the process proceeds to step S4 of the flowchart in FIG. 5, where it is determined whether or not the second key SW2 (transfer start key) is pressed. It is determined whether the transfer command signal is input to the transfer start determination circuit 17 through the signal line e, the switch 16, and the signal line f.

When it is confirmed in this step S4 that the transfer command signal is input to the transfer start judgment circuit 17, the process proceeds to step S5, and from the active terminal t4 of the transfer start judgment circuit 17 to the control terminal of the transfer processing circuit 18. A drive signal is input to t+o.

The data signal of the barcode obtained by the remote control is created into a remote control data signal by the remote control data transfer processing section 22, and is transferred to the host device.

[Problem to be solved by the invention]

In response to the demand for miniaturization of the device, the conventional barcode remote control device described above has the number of parts reduced as much as possible, and the parts used are also made as small as possible.

For this reason, small keys are used for the first key SWI and the second key SW2, and in order to reduce the space occupied, these first and second keys SWI.

SW2 and SW2 are arranged close to each other, and the barcode remote control device is not provided with an indicator light to display the operation of these keys.

For this reason, in the conventional barcode remote control device, as described above, the first and second keys SWI, SW2
These operations are stored in the read start input circuit 1 and the transfer start input circuit 5, respectively, and this state is the state of the first key SWI for inputting the read command signal and the second key SWI for inputting the transfer command signal. The order of key SW2 is determined, and the barcode is read and the remote control data signal created based on the read barcode is transferred.

In this way, the first and second keys SWI are small.

In the conventional barcode remote control device in which SW2 is arranged adjacently, after operating the first key SWI,
There is a possibility that the user intends to operate the second key SW2, but accidentally operates the first key SWI and the second key SW2 at the same time.

When the first key SWI and the second key SW2 are operated simultaneously, the reading start input circuit 1 is activated as described above.
3, the presence or absence of a reading command signal is first determined, and the reading processing circuit 14 performs the reading processing, so that the data signal to be stored in the reading processing circuit 14 by the first operation of the first key SWI is transferred to the reading processing circuit 14. circuit 18
There is a problem in that the data is erased before being transferred as a remote control data signal.

An object of the present invention is to prevent the data signal obtained by the reading process by the first key that has already been operated from being erased even if the first key and the second key are operated erroneously, such as when the first key and the second key are operated simultaneously. An object of the present invention is to provide a barcode remote control device in which a remote control data signal is created based on this data signal, and this remote control data signal is transferred to a host device.

In order to achieve the above object, the present invention provides a first key for inputting a read command signal and a second key for inputting a transfer command signal.
a controller section having a key; a barcode reading processing section connected to the controller section 6 and operated by a reading command signal output from the controller section to read a barcode and obtain a data signal; The controller is connected to the controller and is operated by a transfer command signal output from the controller 1-roller section, takes in the data signal from the barcode reading processing section, encodes this data signal to create a remote control data signal, and sends the remote control to your remote control. A bar code remote control device having a remote control data transfer processing unit that transfers data signals to a host device is opened after the processing in the remote control data transfer processing unit is completed, and inputs the reading command signal to the reading processing unit. The feature is that a gate circuit is provided to perform the operation.

[Effect]

Opened after completion of processing in the remote control data transfer processing section,
By providing a gate circuit for inputting a reading command signal to the reading processing section, the gate circuit is closed when the barcode reading processing section completes the barcode reading process by operating the first key. The input of the reading command signal to the reading processing section is cut off.

Therefore, even if the first key and the second key are operated at the same time, the transfer command signal due to the operation of the second key is only input to the remote control data transfer processing section, and the reading command signal is not transmitted. The previous data signal is not erased when input to the reading processing section.

Therefore, the remote control data transfer processing section is activated by the transfer command signal, a data signal is taken in from the reading processing section, a remote control data signal is created based on this data signal, and this remote control data signal is transferred to the BOST device.

After the processing in the remote control data transfer processing section is completed, the gate circuit described above is opened for the first time, so that the data signal obtained by the barcode reading processing section is not erased and the host device receives accurate remote control data signals. The transfer will take place.

A determination is made as to whether or not the transfer start key (transfer start key) is pressed. However, at this time, the signal line e,
Since f are isolated from each other, the transfer start determination circuit 17
does not detect the operation of the second key SW2, and proceeds to step S3, where it is determined whether the first key (transfer start key) is pressed.

At this time, since the signal lines a and b are connected to each other by the switch 12, a read command signal is input to the read start judgment circuit 13, and the read command signal is inputted to the read start judgment circuit 13, and the flowchart S shown in FIG.
Proceeding to step 4, the read processing circuit 14 is activated by the drive signal from the active terminal t41 of the read start determination circuit 13.
