Abstract

PURPOSE:To simplify a circuit by shifting to execution of a test program if a preparation completion display switch turns on when an electric power source switch is turned on, and executing an on-line connection by the subsequent on when said switch is not turned on. CONSTITUTION:When a switch (SW)2 of a power source 1 is turned on in a state that an on-line setting SW12 is turned on, a microprocessor 4 reads SW information from an input port 9, and decides that a simple body test is designated. A form exists and cover closed state is read from the input port 9, a test program of an ROM5 is started, a data is outputted to an output port 8, a pulse motor is driven 11, a printing head is driven by synchronizing with a rotation of the pulse motor, and a character pattern contained in the ROM5 is outputted and printed. When the power source SW2 is turned on in a state that the SW12 remains opened, and thereafter, the switch 12 is turned on, the operation is shifted to an on-line processing with an external circuit. In this way, an exclusive switch and an exclusive control part for a test are not required, and the circuit is simplified.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a control method for a terminal device, and in particular to a method for controlling the terminal device using a switch and a program that are basically installed in the terminal device. This invention relates to a control method for a terminal device that enables

[Background of the invention]

Conventionally, in a terminal device such as a printer that is integrated into a data processing system, a dedicated device is used to test the mechanism and control section independently (hereinafter referred to as ``performing a unit test''). Testing was made possible by implementing separate control units for switches and dest.

For this reason, there are problems in that the cost of the device increases and the operation becomes complicated.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to solve the two-pronged problem in the conventional terminal device control method, and to provide a terminal device with a test-only switch or a An object of the present invention is to provide a control method for a terminal device that makes it possible to perform a unit test without providing a control section.

[Summary of the invention]

The above-mentioned object of the present invention is to provide a first switch for turning on and off the power, and f4 (B l+ili
In the terminal device having a second switch indicating completion, if the second switch is in the on state at the time the first switch is turned on, a predetermined test program is executed, According to a control method of a terminal device, the second switch is in an off state when the first switch is turned on, and when the second switch is turned on afterwards, an on-line connection with an external device is established. Achieved.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings. In the following description, a cut printer (hereinafter simply referred to as a "printer") will be cited as an example of a terminal device, but the present invention is not limited to this.

FIG. 1 is a hardware configuration diagram of a printer control mechanism that is an embodiment of the present invention. In the figure, 4 is a microprocessor that commands all operations of the printer, 5 is a test program for the printer, and stores character patterns.
6 is a random access memory for storing data, and 7 is an output port for outputting print head control signals.
1-18 is an output port that outputs the pulse motor control 1 to roll signal, and 9 is an input port 1- that reads switch information.
110 is a drive circuit that drives the print head, J is a pulse smoke drive circuit that drives a pulse motor, 12 is an online setting switch, ] 3 is a sensor amplifier circuit, and 7 is a power supply circuit that supplies power to each of the above means. It shows. Note that 1 is an AC power source and 2 is a power switch.

In this embodiment, when the power switch 2 is turned on with the online setting switch 2 turned on, the microprocessor 4 reads the switch information from the input ports 1-9 and recognizes that a unit test is specified. . Next, the Mytalo processor 4 receives the paper from the input boat 9,
The switch information such as the open/close state of the cover is read, and if there is paper and the cover is closed, a program is started for the test stored in the read-only memory 5. After startup, the test program outputs advanced phase data to the output capacitor 1-8, and the pulse motor is rotated via the pulse motor drive circuit 11. Further, in synchronization with the rotation of the pulse motor, the character pattern stored in the two-one-only memory 5 is outputted to the print head drive circuit 10, thereby driving the print head to perform printing.

FIG. 2 shows processing flowchart 1 for printer unit test 1 described above. The operation of this embodiment will be explained below based on the flowchart 1- shown in FIG.

Step]: When the power switch 2 of the printer is turned on, it is checked whether the online setting switch 12 has been turned on for a certain period of time.

This check is performed by time monitoring using a rough 1-timer, and if the online setting switch 12 is on for a certain period of time, it is determined that it is a unit test. Note that by performing the above-mentioned time monitoring, it is possible to distinguish from the case where the online setting switch 12 is turned on immediately after the power switch 2 is turned on, and erroneous designation can be prevented.

Step 2: If it is determined that it is a unit test, next check whether there is paper. This is because, as mentioned above, this embodiment shows the case where the present invention is applied to a cut-sheet printer. When the presence of paper is detected, the cut paper is sucked up to the printing position, and printing and reversing operations are performed. When the predetermined printing and editing operations are completed, the two-marked cut sheet is discharged and waits for sampling. When the cut sheet is extracted, the system waits for the paper again, and it is possible to repeat the unit test.

Step 3 If it is determined in step 1 that the unit test (- is not \), the process moves to online processing when the online setting switch 12 is turned on.

In the above embodiment, an example was shown in which the present invention was applied to a printer, but as mentioned above, the present invention is not limited to this, and can be applied to other terminal devices in general that require unit testing. It goes without saying. It goes without saying that when applied to other terminal devices, it is possible to use a Nast program specific to the terminal device.

〔Effect of the invention〕

As described above, the present invention provides a terminal device including a first switch for turning on and off a power supply, and a second switch for indicating completion of preparation for an external device, in which the first switch When the second
If the first switch was in the on state, a predetermined test program is executed, and if the second switch was in the off state at the time the first switch was turned on and then turned on, the external It is remarkable that it is possible to realize a terminal device control method that enables unit testing without providing a test-dedicated switch or test I-control unit on the terminal device, since online connection with the device is established. This has the following effects.
