Abstract

PURPOSE:To perform printing and tabulation many times and to suppress the occupying time of a computer system to the min., by storing and holding data in a data holding part at once and again performing printing and tabulation in an output part on the basis of the indication of an operator and the stored data. CONSTITUTION:When printing and tabulation are desired to be again performed after both of them are finished, the switch for again indicating printing and tabulation contained in an operating part 3 is turned ON to send an indication signal to a control part 4. The control part 4 receives said indication signal to output a control signal to a data holding part 6 and an output part 5. As a result, required data is read from the data holding part 6 to be sent to the output part 5 and printing and tabulation are again performed in the output part 5 on the basis of the data stored in the operating part 3. When the switch for indicating the clearing of the stored data contained in the operating part 3 is turned ON, this indication signal is sent to a control part 4 to clear the data stored in the data holding part 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device that prints and tabulates data as an external output device for a computer system or the like.

[Prior Art] Conventionally, this type of printing device (printer) receives data from a computer system, etc., and performs printing and tabulation based on this data.

[Problems to be Solved by the Invention] The conventional printing device described above performs printing and tabulation based on data received from a computer system, etc., so printing and tabulation are performed based on data received from a computer system, etc. is only allowed once per pick. Therefore, if it is desired to print and tabulate the same content multiple times, it is necessary to operate the computer system or the like the required number of times. Therefore, there is a drawback that the time required to occupy the computer system or the like increases, which hinders its effective use.

The present invention has been made in view of such problems, and includes:
It is possible to print and tabulate the same content multiple times by operating the computer system, etc. once, and therefore, the time occupied by the computer system, etc. can be minimized and its effective use can be achieved. The purpose is to provide a printing device.

[Means for Solving the Problems] A printing device according to the present invention is a printing device that prints and/or tabulates data as an external output function of a computer system, etc., and is connected to the computer system, etc. so that the data is input. a connector section that stores and holds the data input from the connector section, an output section that performs printing and/or tabulation, and a control section that controls the output section based on the data and controls the data holding section. It has a control section that performs control, and an operation section that outputs instruction signals instructing the control section to print and tabulate.

[Operation] In the printing device of the present invention having the above configuration, data inputted from a computer system etc. via the connector section is stored and held in the data holding section, and the output section prints and/or prints data based on the data. Or tabulation is performed. Further, when printing and/or tabulation is to be performed again, an instruction signal is sent to the control section via the operation section. The control section receives the instruction signal and outputs a control signal to the data holding section and the output section, whereby the output section performs printing and/or tabulation based on the data stored and held in the data holding section.

[Example] Hereinafter, an example of the present invention will be specifically described with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a printing device according to an embodiment of the present invention. In the figure, a signal cable (not shown) for exchanging actual data and control signals with a computer system or the like is connected to the connector section 1. A control unit 4 is connected to the connector unit 1 via an interface unit 2, and the interface unit 2 connects equipment such as a computer system connected to the signal cable to the control unit 4 of the device. It has become.

The control section 4 is further connected to an operation section 3, an output section 5, and a data holding section 6. The data holding unit 6 stores and holds data that has reached the interface unit 2 based on instructions from the control unit 4.

The operation unit 3 outputs a support signal that instructs to perform printing and tabulation again based on the data stored in the data holding unit 6, or instructs to clear the stored data. For this purpose, various switches and the like are provided for the operator to operate. The output section 5 is the control section 4
Printing or tabulation is performed based on the instructions.

Next, the operation of the printing device having the above configuration will be explained. First, among the data and control signals that arrive from the computer system etc. via the connector section 1 to the interface section 2, the control signal is used to connect equipment such as the computer system and this printing device, while the data is The data is stored in the data holding section 6 under the control of the control section 4. This data also includes special data such as newline and null codes. At the same time, this data is decoded by the control section 4 and used to control the control section 4 itself, as well as used as data to the output section 5.

Based on the data that has reached the output section 5, printing or tabulation is performed in the output section 5. After this printing and tabulation is completed, if you want to perform printing and tabulation again, turn on the switch included in the operation section 3 for instructing printing and tabulation again, and this instruction signal will be sent to the control section. Sent to 4. The control section 4 receives this instruction signal and outputs a control signal to the data holding section 6 and the output section 5. As a result, required data is read from the data holding section 6 and sent to the output section 5. Then, in the output unit 5, printing and tabulation are performed again based on the data stored in the data holding unit 6.

Furthermore, when a switch included in the operation section 3 that instructs clearing of stored data is turned on, this instruction signal is sent to the control section 4, and upon receiving this instruction signal, the control section 4 controls the data holding section 6. send a signal.

As a result, the data stored in the data holding section 6 is cleared. Note that the storage contents of the data holding section 6 may be cleared automatically each time new data is inputted to the control section 4 from a computer system or the like, regardless of the operation of a switch on the operation section 3. Furthermore, data transfer to the data holding section 6 may be performed only when an instruction signal is input from the operation section 3 or the like.

[Effects of the Invention] As explained above, the printing device of the present invention temporarily stores and holds data received from a computer system, etc. in the data storage unit, and prints the data based on the stored data based on instructions from the operator. Since printing and tabulation are performed again in the output section, printing and tabulation can be performed as many times as desired, and even if you want to print and tabulate the exact same content multiple times, it is easy to print and tabulate from a computer system, etc. Since data need only be entered once, the time occupied by the computer system for printing and tabulation can be kept to a minimum, resulting in the effective use of the computer system. .
