Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. A personal computer test apparatus using a mouse according to the present invention includes a plurality of sub CPUs 11a to 11d, a main CPU 12, a clock generator 14, an operation switch unit 15, and the like. The reset part 16 is provided. The personal computers 10a to 10d are connected to each sub CPU 11a to 11d one by one, and the first instruction applied from the personal computers 10a to 10d connected to the sub CPUs 11a to 11d is transmitted to the main CPU 12 side. Then, the second command applied from the main CPU 12 is outputted to the personal computers 10a to 10d connected to it. In addition, the main CPU 12 is connected between the mouse 13 and the sub CPUs 11a to 11d to check whether the first and second commands are transmitted and received between the mouse 13 and the sub CPUs 11a to 11d. Thus, the first command applied from the sub CPUs 11a to 11d is transmitted to the mouse 13 side, and the second command applied from the mouse 13 is transferred to the sub CPU 11a to 11d side. The clock generator 14 generates a clock CLK and supplies the clock CLK to the sub CPUs 11a to 11d and the main CPU 12 as an operation clock, and the reset unit 16 supplies the sub CPUs 11a to 11d. ) And a reset signal are applied to the main CPU 12 side to initialize the sub CPUs 11a to 11d and the main CPU 12. The operation switching unit 15 controls the sub-CPUs 11a to 11d connected to the personal computer by manual operation of the test operator when a personal computer that does not operate normally while testing the personal computers 10a to 10b exists. Stop operation

On the other hand, the sub CPUs 11a to 11d operate according to a predetermined program, and the program is stored in a memory built in itself. Similarly, the main CPU 12 operates by a predetermined program, which is stored in a built-in memory. Accordingly, the sub CPUs 11a to 11d and the main CPU 12 perform a repetitive operation when power is applied. Each of the sub CPUs 11a to 11d is connected to the mouse connectors of the personal computers 10a to 10d to receive the first command for the mouse 13 from the personal computers 10a to 10d to the main CPU 12. The second command received from the main CPU 12 is transferred to the personal computers 10a to 10d.

Each sub CPU 11a to 11d performs operations in the order shown in FIG.

First, when the power is input to the sub CPUs 11a to 11d due to the power being applied (step 21), the sub CPUs 11a to 11d operate as the test operator operates the switch of the reset unit 16. After performing the initialization operation (step 22), it is checked whether or not the personal computers 10a to 10d connected to the computer are operated (step 23). When the personal computers 10a to 10d are operated, the personal computer connected to the user is checked. It is checked whether or not the first command for the mouse is input from the computers 10a to 10d (step 24). At this time, when the first commands for the mouse are input from the personal computers 10a to 10d, the sub CPUs 11a to 11d transmit the first commands to the main CPU 12 side (step 25), and the step 24 is performed. When the first command for the mouse is not input from the personal computers 10a to 10d, the controller checks whether or not the second command is input from the main CPU 12 (step 26). The sub CPUs 11a to 11d transmit the second command to the personal computers 10a to 10d connected thereto when the second command is input from the main CPU 12 in step 26 (step 27). The flow returns to step 24 to perform the repeat operation, and when the second command is not input from the main CPU 12, the flow returns directly to the step 24 to perform the repeat operation.

In addition, the main CPU 12 performs operations in the order shown in FIG.

First, in a state where power is input to the main CPU 12 due to the power supplied to the personal computers 10a to 10d (step 31), the test operator operates the switch of the reset unit 16 as the main CPU. 12, after performing the initialization operation (step 32), it is determined whether the first instruction for the mouse 13 is input from the sub CPUs 11a to 11d for the mouse 13 from the sub CPUs 11a to 11d. (Step 33) At this time, when the first command for the mouse 13 is input from the sub CPUs 11a to 11d, the main CPU 12 transmits the first command to the mouse 13 side. After that (step 34), the operation returns to the step 33, and if the first command for the mouse 13 is not input from the sub CPUs 11a to 11d, the second command is input from the mouse 13 or not. It is confirmed whether or not (step 35). When the second command is input from the mouse 13 in step 35, the main CPU 12 transmits the second command to the sub CPUs 11a to 11d (step 36), and returns to step 33 to repeat the operation. If the second command is not input from the mouse 13, the process returns directly to the step 33 to perform the repeated operation.

That is, the personal computer test apparatus of the present invention connects the personal computers 10a to 10d one by one to each of the sub-CPUs 11a to 11d one by one, and supplies the first instruction applied from the personal computers 10a to 10d to the main CPU. (12) is transmitted to the mouse 13 side, and the second CPU 11a to 11d transmits a second command applied from the mouse 13 to the main computer 12 by the sub CPUs 11a to 11d. By outputting to, a plurality of personal computers 10a to 10d are simultaneously operated by a single mouse 13 to test whether or not they operate normally.

As described above, the present invention can test multiple personal computers simultaneously by using a single mouse in a personal computer production process, thereby reducing the personal computer test time and efficiently testing a large number of personal computers. Will be improved.
