To provide. The switch means 46 is for selecting an operation confirmation inspection mode, which will be described later. The CPU 41 is a central processing unit, and the gate array 42 is an electronic blackboard device.
When U41 sends a signal, it controls the input / output of the signal. Further, the ROM 43 stores various programs for controlling the electronic blackboard device, and the RAM 44
Stores handwritten information read by the reading means 14.

The CPU 41 has a line counter for counting the reading area of the screen sheet 1 as the number of lines. More specifically, the line counter receives a signal sent from the gate array 42 at a constant interval by the CPU 41, counts the number of lines set on the screen sheet 1 based on this signal, and counts the number of lines set on the screen sheet 1. The reading area is grasped and, for example, the length of the first writing surface 1a is set to 2215 lines.

When using the electronic blackboard device configured as described above, the power key 22 of the operation unit 4 of FIG.

In this example, the switch means 46 shown in FIG. 4 corresponds to a switch in the operation confirmation inspection mode, and the switch means 4
When 6 is operated to turn it on and then the power key 22 is turned on, the control means shifts to the operation confirmation inspection mode, and the operation confirmation inspection is automatically started.

Next, the power key 22 of the electronic blackboard device is turned on.
To In S1, it is determined whether the switch means 46 in the operation confirmation inspection mode provided in the electronic blackboard device is ON.

When the switch of the operation confirmation inspection mode is ON, the CPU 41 turns ON the flag of the operation confirmation inspection mode (S2), the initialization process is performed in S3, and the process proceeds to S4.

At S4, the operation unit is inspected. In the operation section inspection, when the switch means 46 is operated,
The CPU 41 displays all the displays L on the operation unit of the electronic blackboard device.
The ED is turned on, and the LED lighting inspection (S4a) is performed. When the inspector confirms that all the display LEDs are normally turned on, the process proceeds to S4b to inspect the operation keys.

This operation key inspection is for confirming that all the operation keys in the operation section 4 operate normally. In this inspection, the operation keys are set to correspond to all the display LEDs that are lit in the LED lighting inspection (S4a), and when the inspector presses the operation key, the display LED corresponding to the operation key is displayed. It's turned off. This is to confirm that the operation key operates normally.

In this example, the feed key 23 and the return key 2

This reading density inspection is to confirm the reading density of the reading means 14, and is set in advance while the inspection sheet is stuck on the first writing surface 1a of the electronic blackboard device and the screen sheet 1 is conveyed. The reading density of the reading plate is read by the reading means 14 while sequentially switching the reading densities in three levels, that is, the three reading densities of "light", standard, and "dark", and the reading density is inspected. And
The contents read by the reading means 14 are stored in the RAM 44.

Then, in S5b, an additional copy / sheet return inspection is performed. Additional copy / sheet return inspection is S5
an additional copy inspection (additional output inspection) for inspecting whether the writing contents read by the reading means 14 stored in the RAM 44 in a in FIG. 1 writing surface 1
A sheet return inspection is performed in parallel to confirm that a is returned to the position before the start of reading.

After the additional copy inspection and the sheet return inspection, the operation confirmation inspection mode ends and the power key 22 is turned on.
Set to FF.

On the other hand, if the switch in the operation confirmation inspection mode is not turned on in S1, the process proceeds to S6, where after initialization processing is performed, the standby state for normal use of the electronic blackboard device (S7). ). Then, as described above, the electronic blackboard device is used (S8), and after use,
The power key 22 of the electronic blackboard device is turned off.

The details of the above-mentioned read density inspection are as follows.
An inspection plate 47 having a length of 150 mm and a width of 450 mm as shown in FIG. 7 is attached to the first writing surface 1a of the electronic blackboard device prior to the reading density inspection. The inspection plate 47 has inspection sheets C1 to C5 having five different brightness levels on its surface. Three inspection plates 47, the first writing surface 1a of the screen sheet 1

Can read the two dark inspection sheets C4 and C5, and when the read density is set to "dense", the four inspection sheets C2 to C5 other than the brightest inspection sheet C1 among the five-stage inspection sheets are displayed. It is set so that it can be read, and the inspector visually determines whether or not the printed paper X conforms to it.

Further, in the present invention, the ROM 4 is arranged so that the information read at the three reading density levels is output on one sheet.
Since it is controlled by the program stored in 3, the inspection time can be shortened and the paper can be saved compared to the case where the inspection was performed by printing on one sheet for each read density. can do.

According to the invention of claim 4, as the operation confirmation inspection, the operation key inspection for confirming that the operation keys normally operate is provided, so that the connection failure of the operation keys can be found before shipment. It is possible to reduce the shipment of defective products of the electronic blackboard device.

According to the fifth aspect of the present invention, in the operation key inspection, when the operation keys are operated, the operation keys are turned off by turning off the lit display LEDs corresponding to the operated operation keys. Since it is an inspection for confirming that the normal operation is performed, it is possible to accurately detect a connection failure of each operation key and the like, and it is possible to reduce the shipment of defective products of the electronic blackboard device.

According to the sixth aspect of the present invention, as the operation confirmation inspection, the reading density inspection for confirming the reading density of the reading means is provided. Therefore, the contents written on the screen sheet are accurately printed according to the reading density. be able to.

According to the seventh aspect of the invention, the reading density inspection is performed by sequentially changing the density of the reading density while the writing sheet is conveyed, and the reading means provides the reading density on the surface of the inspection plate attached on the writing sheet. Since it is an inspection for reading the inspection sheet, it is possible to perform the inspection of the reading density in a plurality of stages by one inspection, and the inspection can be made efficient.

According to the eighth aspect of the present invention, as the operation confirmation inspection, since the additional printing inspection for additionally printing the writing content read by the reading means on the print sheet by the printer is provided, the defect of the additional printing is accurately detected. It is possible,
It is possible to reduce the shipment of defective products of the electronic blackboard device.

According to the invention of claim 9, as the operation confirmation inspection, the sheet return inspection for confirming that the writing sheet after the reading of the writing content is normally returned to the position before the start of reading the writing content is provided. It is possible to accurately detect sheet return defects and reduce shipment of defective electronic blackboard devices.

According to the eleventh aspect of the present invention, the operation confirmation inspection sequentially performs the LED lighting inspection, the operation key inspection, the read density inspection, the additional output inspection, and the sheet return inspection. The inspection can be performed continuously, and the inspection can be made efficient.
