Abstract

PURPOSE:To set priority relation between a function set by a control panel and a command transmitted from a host device by the control panel by making the command from the host device preferential when an operation part is not operated and making the function set by the operation part preferential when the operation part is operated. CONSTITUTION:When a control panel 4 is operated and the function corresponding to the command is set, set function information updates the contents of a mode storage part 6, and the operating mode of a printer is turned to an operating mode based on the setting function. On the other hand, the execution of operating the control panel 4 is stored in an operation storage part 5, and a command selection part 3 inhibits the passage of the command inputted from an I/F 1 by inputting an operating signal after the operating signal is stored in the operation storage part 5. Then, the command inputted from the host device is made invalid until the operation storage part 5 is cleared. Data inputted to a control part 2 are converted into real printing data while referring to the set operating mode.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peripheral device such as a printer, and more particularly to setting an operation mode of the peripheral device.

[0002]

2. Description of the Related Art In recent years, a selection mechanism for selecting various functions has been added to an operation unit of a peripheral device such as a printing device, and many of these functions are output from a host device such as a host computer. In many cases, it is configured to be selected / released by a command to be performed. Therefore, even if the operator operates the operation panel of the printing device and selects / sets a certain function, a command to cancel that function is output from the host device, and at that time, the function set from the operation panel is invalidated. It may become.

Further, in the case where the operation panel operation is uniquely prioritized, the command from the host device is always ignored, and the result assumed by the program of the host device cannot be obtained. ..

[0004]

As described above, although the peripheral device such as the printing device has the mode selection function capable of setting a desired function from the operation panel, it is transmitted from the host device. Since the priority relation with the command is fixed and lacks flexibility, there is a problem that the operation of the operation panel is invalidated or the peripheral device is not controlled according to the command transmitted from the host device.

The present invention has been made in view of the above circumstances, and provides a peripheral device capable of flexibly setting the priority relation between the function set on the operation panel and the command transmitted from the host device on the operation panel. The purpose is to provide.

[0006]

In order to achieve the above object, the present invention has a function corresponding to a part or all of the above command in a peripheral device which operates according to a command transmitted from a host device. An operation unit that can set this function, an operation storage unit that stores that the operation unit has been operated, a function that is set by the operation unit based on a storage state of the operation storage unit, and a transmission from the host device. And a command selection unit that validates one of the received commands.

[0007]

Since the present invention is configured as described above, the command selection unit validates one of the function set by the operation unit and the command transmitted from the host device based on the storage state of the operation storage unit. As a result, priority determination is realized by giving priority to the command transmitted from the higher-level device when the operation unit is not operated, and giving priority to the function set in the operation unit when the operation unit is operated. It

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a peripheral device according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes an interface (hereinafter referred to as I / F) for receiving data and commands transmitted from a host device such as a host computer.
The control unit 2 for converting the data received by the I / F1 into print data printed by a peripheral device, for example, a printing device.
And the command is output to the command selector 3 which gates this command.

Reference numeral 4 is a touch panel or the like, which has a function corresponding to a part or all of commands transmitted from the host device, and is an operation panel capable of setting a function corresponding to a command by operating the touch panel. When the operation panel 4 is operated, the operation storage unit 5 stores the operation of the operation panel 4. The operation signal stored in the operation storage unit 5 indicating that the operation panel 4 has been operated is cleared by pressing the same portion of the operation panel 4, and the function set from the operation panel 4 is canceled.

On the other hand, the function signal set on the operation panel 5 is output to the mode storage section 6 which stores the operation mode of the printing apparatus. The operation mode stored in the mode storage unit 6 is set based on the command passed through the command selection unit 3 or the function set on the operation panel 4. That is, when the operation panel 4 is not operated, the command input to the command selection unit 3 passes through the command selection unit 3 and is input to the mode storage unit 6, and the mode storage unit 6 is set based on this command. The operating mode of the printer to be memorized, and when the operation panel 4 is operated,
The output of the command input to the command selection unit 3 by the operation signal of the operation panel 4 stored in the operation storage unit 5 is prohibited, the function set in the operation panel 5 is input to the mode storage unit 6, and the mode is set. The storage unit 6 stores the operation mode of the printing device set based on this function. The control unit 2 converts the data input from the I / F1 into print data which is actually printed by the printer according to the operation mode stored in the mode storage unit 6. A printing unit (not shown) performs the printing operation with the converted print data.

Next, the operation of the embodiment of the present invention having the above construction will be described.

In the usual case, the command received by the I / F 1 passes through the command selection section 3 and the mode storage section.
Update the contents of 6 and set the operation mode of the printer to the operation mode based on the command. On the other hand, the data transmitted from the host device and received by the I / F1 is directly input to the control unit 2 and converted into print data which is actually printed by the printing device while referring to the updated contents of the mode storage unit 6. It

By the way, when the operation panel 4 is operated and the function corresponding to the command is set, the set function information updates the contents of the mode storage section 6 to set the operation mode of the printer. Set to. On the other hand, after the operation storage unit 5 stores the operation of the operation panel 4 and the operation storage unit 5 stores the operation signal, the command selection unit 3 after the operation signal is input receives the operation signal.
The command input from F1 is prohibited, and the command input from the host device becomes invalid until the operation storage unit 5 is cleared. Further, the data input to the control unit 2 is converted into actual print data while referring to the operation mode set based on the setting function.

In the above embodiment, the printer is applied as the peripheral device, but the present invention is not limited to this, and a device having an operation panel capable of setting a function corresponding to a command transmitted from a higher-level device. If applicable, it can be applied in the same way.

Further, the present invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0018]

As described above in detail, according to the peripheral device of the present invention, the command selection unit has the function set by the operation unit based on the storage state of the operation storage unit and the command transmitted from the host device. Since one of them is valid, the function set in the operation unit is given priority by operating the operation unit as necessary, and the command sent from the host device when the operation unit is not operated. Can be prioritized. Therefore, it is possible to flexibly determine the priority of the peripheral device.
