In the above configuration, the operation of the CPU 21 executed by the CPU 21 will be described below with reference to flowcharts.

FIG. 6 is a flowchart showing the overall processing flow. When the display program, display contents, and operation of the liquid crystal display unit 10 as the operation test apparatus 20 are checked, the original data (image A CD storing data, a display program, and control data for managing packet data in connection with a test operation, etc.) is loaded into the apparatus 20, and the original data relating to the model to be inspected is read from the CD. Load to memory 22 (step S
2). That is, first, when the model display button 41 is clicked in the control window W2, as shown in FIG. 3B, a title name corresponding to the model in the loaded CD is displayed. Move the cursor to the display position of the title name to be
When the user double-clicks on, all data relating to the designated model is loaded into the memory 22.

Next, the up and down arrows are clicked in the packet area of the control window W2, and the transmission cycle in the packet area is set to a required time from 2 ms to 32 ms (step S4), and a stop symbol is set. A stop symbol is set in the window W3 (step S
6).

In this state, it is determined which of the forward play button 44, the reverse play button 45, the forward one frame forward button 46, and the forward one frame forward button 47 has been designated (steps S8 to S14). If neither designation has been made, the process returns to step S4 and repeats such determination processing. On the other hand, if the forward playback button 44 has been designated (YES in step S8), the process proceeds to step S16, where the forward playback processing is performed by the forward playback processing unit 214, and the reverse playback button 45 is designated. If YES (YES in step S10), the process proceeds to step S18, in which the reverse playback processing unit 215 executes the reverse playback process, and if the forward one frame forward button 46 is designated (YES in step S12). ), Step S20
Then, if the forward one-frame feed processing is executed by the forward-direction frame forward processing unit 216 and the backward one-frame forward button 47 is designated (YES in step S14),

FIG. 7 is a flowchart showing a subroutine for setting a stop symbol.

Here, it is determined which of the left stop symbol, the middle stop symbol and the right stop symbol has been clicked (pressed) (steps S32 to S36). If the left stop symbol has been designated (YE in step S32)
S), as shown in FIG. 4A, the cursor is moved (black and white reversal position) to set one symbol from "one" to "nine" and a required number of symbols (step). S
38). If the middle stop symbol has been designated (YES in step S34), the cursor is moved to the position shown in FIG.
According to the same procedure as in the case of above, one symbol is set from "one" to "nin" and a required number of symbols (step S40). If a right stop symbol has been designated (YES in step S36), one symbol is selected from "one" to "nin" and a required number of symbols by the same procedure as in the case of FIG. Set (Step S4
2). Thus, in steps S32, S34 and S36,
When the left, middle, and right stop symbols are specified in the stop symbol window W3, the operation check is performed to determine whether or not the stop symbol at each position matches the specified symbol. The code is also displayed at the corresponding positions of the stop symbol window W3 and the monitor window W1, and the code designating the symbol is transmitted to the liquid crystal display unit 10 via the cable Ca and displayed on the LCD 13, so that the monitor window is displayed. By comparing W1 with the difference between the symbols displayed on the LCD 13, the CPU 11 of the liquid crystal display unit 10 and the character data memory 1 are compared.
It can be visually confirmed whether or not the correspondence with 22 is wrong. Therefore, in this case, since only the difference in the stop symbols is confirmed, the flow is completed.

On the other hand, steps S32, S34 and S36 are N
If O, then it is determined whether or not the variation method has been selected (step S44). As described above, the variation method refers to a display program that executes each of the variation patterns set according to the pachinko game situation, and as shown in FIG. By moving the cursor (the black-and-white reversal position in FIG. 4C), the variation pattern desired to be inspected can be designated. If none of the variation methods is selected, the flow ends, and if one is selected (step S4)
4), the data specifying the selected variation method is guided to the memory 221 to execute the display program, and the data specifying the variation method is transmitted to the cable Ca.
Is transmitted to the CPU 11 of the liquid crystal display unit 10 via the CPU 11, and the CPU 11 receives the specific data and instructs execution of the display program in the program memory 121 (step S46). Here, the fluctuation pattern displayed on the monitor window W1 is the LC pattern of the liquid crystal display unit 10.
If the change pattern is the same as the change pattern displayed on the D13, the program memory 1 is sent to the CPU 11 of the liquid crystal display unit 10 to specify the change method.
It can be confirmed that both the VDP 21 and the VDP 14 operate normally. On the other hand, when a difference occurs between the monitor window W1 and the fluctuation pattern of the LCD 13, the liquid crystal display unit 1
0 side CPU 11, program memory 121 and VDP
It can be seen that, in any one or more of the fourteenth examples, the correspondence with the specific code (display program of the variation pattern specified for the specific code) is incorrect.

FIG. 8 is a flowchart showing a subroutine of the forward reproduction process.

Here, this flow is started by clicking the forward reproduction button 44 of the control window W1. First, it is determined whether or not reproduction from the first data is instructed (step S60). If so, a reproduction counter for instructing packet data of each column, which is built in the CPU 21, is set to a value of 0. (Step S62). On the other hand, if it is not playback from the head data, it is determined whether a packet has not been loaded yet (step S64), and the column information (in conversion time) displayed at the head or “from here” of the control window W1. If the packet data from (displayed) has not been loaded, the stop symbol window W3
The data is created in accordance with the stop symbol set in (step S66). That is, the stop symbol window W
The reproduction start column is reset so that the reproduction operation is stopped at the stop symbol of No. 3.

Subsequently, the flow advances to step S68 to determine whether or not the stop button 49 has been pressed (step S6).
8) If pressed, stop is instructed, and the flow ends as it is. On the other hand, if the stop button 49 has not been pressed, one row of packet data is output (step S70), and then the reproduction counter is incremented by 1 (step S72). Then, it is determined whether or not the reproduction counter has reached the value of the last column, that is, whether or not the transmission of the packet data of all the columns has been completed (step S74).
Returning to 68, the operation of transmitting the packet data of the next column is repeated on condition that the stop button 49 is not pressed.
Then, when the transmission of the packet data of all the columns is completed, it is determined that the reproduction process has been completed, and the present flow is terminated.

FIG. 9 is a flowchart showing a subroutine of the reverse reproduction process.

Here, this flow is started when the reverse playback button 45 of the control window W1 is clicked. First, it is determined whether or not the reproduction from the last data is instructed (step S80). If so, the reproduction counter for indicating the packet data of each column built in the CPU 21 is set to the value of the last data position. Is set to (step S82). On the other hand, if it is not the backward reproduction from the last data, it is determined whether or not the packet has not been loaded yet (step S84), and the packet from the head or the column displayed in “here” of the control window W1 is determined. If the data has not been loaded, data is created according to the stop symbol set in the stop symbol window W3 (step S86). That is, the reverse reproduction start column is reset so that the reverse reproduction operation stops at the stop symbol in the stop symbol window W3.

Subsequently, the flow advances to step S88 to determine whether the stop button 49 has been pressed (step S8).
8) If pressed, stop is instructed, and the flow ends as it is. On the other hand, if the stop button 49 has not been pressed, one row of packet data is output (step S90), and then the reproduction counter is decremented by 1 (step S92). Then, it is determined whether or not the reproduction counter has reached the value of the first row, that is, whether or not transmission of packet data of all columns has been completed (step S94).
The operation for transmitting the packet data of the next column is repeated on condition that the stop button 49 is not pressed. Then, when the transmission of the packet data of all the columns is completed, it is determined that the reproduction process has been completed, and the present flow is terminated.

FIG. 10 is a flow chart showing a subroutine of the forward one frame forward processing.

Here, this flow is started when the forward one-frame forward button 46 of the control window W1 is clicked. First, it is determined whether or not the reproduction counter is smaller than the value of the last row of the packet (step S100). If the value is larger than the value in the last row, there is no packet in the last row, so the pattern of the packet data in the last row is displayed, and the flow ends without any change. On the other hand, if the value of the reproduction counter is smaller than the value of the last column (NO in step S100), the packet data of the column specified by the value of the reproduction counter is output (step S102). Are read out from the character data memory 222 and displayed on the monitor window W1.
When the VDP 14 receives each symbol code of this packet code from the CPU 11, the corresponding symbol is read from the character data memory 122, and the VDP 14 is placed at a predetermined position on the display surface of the LCD 13 respectively. Display. Next, the reproduction counter is incremented by 1 (step S10).
4), end this flow.

FIG. 11 is a flowchart showing a subroutine of the reverse one-frame feed process.

Here, this flow is started when the reverse one-frame forward button 47 of the control window W1 is clicked. First, it is determined whether or not the reproduction counter has the value 0 indicating the front row of the packet (step S).
110). If the value is 0, since there is no packet in the front row, the symbol of the packet data in the front row is displayed, and the flow is finished as it is to end the flow. on the other hand,
If the value of the reproduction counter is larger than the value 0 indicating the front row (NO in step S110), the packet data of the column specified by the value of the reproduction counter is output (step S112), and the packet data in the packet specified by the reproduction counter is output. Each symbol code is read from the character data memory 222 and displayed on the monitor window W1, and this packet code is transmitted to the CPU 11 of the liquid crystal display unit 10 via the cable Ca, and the VDP 14
When each symbol code of this packet code is received from the CPU 11, the corresponding symbol is read from the character data memory 122 and displayed at a predetermined position on the display surface of the LCD 13. Next, the reproduction counter is decremented by 1 (step S114), and this flow ends.

As described above, the design corresponding to one row of packet data and the corresponding symbol are simultaneously displayed on the monitor window W1 and the LCD 13 of the liquid crystal display unit 10.
In the forward reproduction or the reverse reproduction, it is possible to surely confirm that it is difficult to accurately confirm the difference between the respective frames due to the change of the image in units of frames.

FIG. 12 is a flowchart showing a subroutine of a packet editing process.

Here, this flow is started by clicking the right button of the mouse 25 in the packet window W4 shown in FIG. Mouse 25
The screen is switched to the screen shown in FIG. 5B by the operation of. In this state, the cursor (black / white inverted portion) is designated to the symbol code desired to be changed (edited) by the keyboard 24 or the mouse 25, and the code is inputted from the keyboard 24. Is performed (step S120). When a new symbol code is input, subsequently, it is determined whether a transmission instruction for a packet including the symbol code, that is, whether the packet load button 43 has been pressed (step S122). If the packet load button 43 is not pressed, it waits until it is pressed, and if the packet load button 43 is pressed,
This one column of packet data is output to the virtual CPU 221 (step S124), and the virtual VDP 212 reads out the symbol data corresponding to the symbol code from the memory 222 and displays it on the monitor window W1, and displays the changed symbol code. Packet data containing
When the VDP 14 receives each symbol code of this packet code from the CPU 11, the VDP 14 reads the corresponding symbol from the character data memory 122, and
13 at predetermined positions on the display surface.

As described above, by changing a part of the symbol code which covers a part of the packet data in one column, only the symbol at the position designated to be changed is displayed on the monitor window W 1 and the LCD 13.
It is possible to easily confirm whether or not there is a similar change between.

In the above-described embodiment, only one of the symbols arranged in a band is normally displayed as the stop symbol, and the entire symbol is displayed by clicking the mouse 25. You may make it always display all the belt-shaped symbols of each of the left, the middle, and the right. By doing so, it becomes easy to grasp the next stop symbol at the time of frame advance designation or the like, and the collation work can be made more efficient.

In the present embodiment, the monitor window W1 in the monitor 23 is set to a predetermined size. However, the size switching icon menu "size switching buttons (+), (-)" is used in the control window. W2
May be provided at appropriate places in the display unit, and may be appropriately set for each display unit or according to the form of the symbol. In this way, a size that can be easily collated is always obtained, so that collation work is facilitated.

Each window of the monitor 23 shown in FIG. 2 is not limited to this arrangement, and various arrangements can be set in consideration of the ease of setting and collation of inspection items.

By taking in the main body,
A plurality of image data and a display program (already downloaded from the same original storage medium) of a plurality of image data that are supposed to be stored in the display unit are fetched, and an operation test is performed using the virtual display unit. If the structure of the display unit is common, an operation test can be easily performed with respect to all display units with a simple configuration, and is applicable to all models (types of image data and display programs). . Also, since the same screen is displayed in the form of a reference image and a reference image so as to be collatable, it is easy to confirm the difference.

Further, since a plurality of image data are specified in a time series according to the display program and a variation pattern based on the plurality of images is displayed, abnormality or normality in an operation state in an actual operation state is determined. You can check.

An arbitrary one of the plurality of image data is
Since the frame is designated, it is possible to accurately confirm the difference between the two images in each frame. This is particularly effective in a mode in which there are a plurality of similar symbols.

Further, on the display screen, a plurality of images can be displayed in three places, respectively. Since the image data of the image to be displayed in each of the above-mentioned places is individually designated, each display place is designated. It is possible to confirm the normality of the abnormality, and it is possible to make a more detailed judgment on the difference.

In addition, since both the monitor and the display unit are composed of liquid crystal display elements, it is possible to perform operation tests on liquid crystal display elements applied in various fields with versatility.
