Description

Description: TECHNICAL FIELD The present invention relates to a printer.

[Conventional technology]

In a conventional printer, when a code indicating a character type, a character size, a character pitch number, a line feed operation, and the like is sent from a higher-level device, the printer operates according to the sent code.

[Problems to be solved by the invention]

The conventional printer described above does not operate unless a code is sent from a higher-level device. Therefore, there is a disadvantage that the operator must operate the higher-level device every time the printer is operated. In such a case, the operation of the host device must be interrupted in order to operate the printer.

[Means for solving the problem]

A printer according to the present invention is a printer that performs printing in accordance with a code sent from a higher-level device for a print instruction, a switch capable of setting the code, a display unit that displays a code set by the switch, and a switch. And a data processing unit for processing the code set by the switch in the same manner as that sent from the host device when the code is set and the instruction to execute the set code is issued. [Operation] A switch for setting the code is provided, and the code set by operating the switch is executed in the same manner as the code sent from the higher-level device, so that the operator can operate the printer without operating the higher-level device. Can be made the same.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the printer according to the present invention, FIG. 2 is a partial plan view showing an arrangement of a main part of an operation panel unit 14 shown in FIG. 1, and FIG. 6 is a flowchart showing a process of a unit 15.

The printer according to the present embodiment includes a printing unit 11 and an interface unit.
It is composed of 12, a data storage unit 13, an operation panel unit 14, and a data processing unit 15.

The printing unit 11 performs operations such as printing and line feed according to instructions from the data processing unit 14. The interface unit 12 receives various 8-bit codes sent from an upper device (not shown).
The data storage unit 13 stores, among the codes processed by the data processing unit 15, codes that are held and used, such as codes for setting the number of character pitches, the character size, and the like. The operation panel unit 14 has switches 21, 22, 23, 24, 25 and a display unit 26. The switches 21, 22, 23, 24, and 25 are all turned on when pressed. The display unit 26 is composed of two sets of 7-segment light emitting diodes in order to display 8 bits by a 2-digit hexadecimal number. The data processing unit 15 operates in the same manner as the conventional mode in which the interface unit 12 receives a code received from a higher-level device (hereinafter, referred to as a first mode) and by operating the switches 21, 22, to 25 of the operation panel unit 14. A mode (hereinafter, referred to as a second mode) for receiving a set 8-bit code.

Next, the processing in the second mode of the data processing unit 15 will be described. Here, for convenience of explanation, the 8-bit code is divided into upper 4 bits and lower 4 bits, and each is represented by one digit hexadecimal number.

Since the data processing unit 15 is normally in the first mode, the data processing unit 15 first determines whether or not to enter the second mode (step 31). That is, when the operator presses the switch 22 once while pressing the switch 21, the data processing unit 15 enters the second mode. In the second mode, the data processing unit 15
Initialize the bit code to “00” (step 32),
“00” is displayed on the display unit 26. Next, the data processing unit 15
Determine whether to return to the first mode (Step 3
3). That is, when the operator presses the switch 22 twice while pressing the switch 21, the data processing unit 15 returns to the first mode. When the mode is not returned to the first mode, the data processing unit 15 accepts a code setting by operating the switches 23 and 24 (step 34). That is, every time the switch 23 is pressed, the value of the upper 4 bits of the code changes from 0 → 1 → 2 →... → F → 0 →. Each time the switch 24 is pressed, the value of the lower 4 bits of the code changes in the same manner as in the case of the upper 4 bits.

Next, the data processing unit 15 determines whether to execute the code thus set (step 35). That is, when the switch 25 is pressed, the data processing unit 15 executes the set code (step 36). When executing a code such as a character or a line feed, the data processing unit 15 converts the code into data in a format in which the printing unit 11 operates, and outputs the converted data to the printing unit 11. Further, when executing a code for setting the number of character pitches and character size, the data processing unit 15 stores the code in the data storage unit 13 and stores the code stored when processing the code such as a character. Process in combination. The code stored in the data storage unit 13 is held until a new code replacing it is stored. After executing the code, the data processing unit 15 returns to step 33, and repeats the above-described processing until it determines to return to the first mode.

 Next, an execution example of the code is shown.

For example, when three codes “41, OD, OA” are executed, the character “A” is printed and a line feed operation is performed.
Further, for example, if the four codes “1B, 65, 32, 32” are codes for enlarging a character vertically and horizontally twice, when this code is executed, the data processing unit 15 converts the character code from the next. When received, the received code is enlarged and printed twice vertically and horizontally.

〔The invention's effect〕

As described above, the present invention includes a switch for setting a code, and executes the code set by operating the switch in the same manner as the code sent from the higher-level device. There is an effect that the printer can be operated without operating the device, and as a result, there is an effect that it is not necessary to interrupt the operation of the host device in order to operate the printer.
