02-1 and 302-2 are provided, and these two accuracy reference mark areas 302-1 and 302-2 are arranged at both ends of the user-written mark area 305.

With such a configuration, every time the general information entered by the user is input, the reading sensitivity of the reading unit of the information reading processing device can be adjusted twice before and after reading the general information. Since it is performed, more reliable sensitivity adjustment becomes possible.

FIG. 3 shows another modification of the adjustment mark sheet shown in FIG. In this modification, both the user-written mark area and the accuracy reference mark area are recorded in the area 306. That is, in this modified example, the accuracy reference mark is previously recorded in the entire user entry mark area in a camouflaged state so as not to disturb the user to enter general information. With this configuration, the accuracy reference mark can be read together with the general information entered by the user, and the sensitivity of the reading unit can be adjusted along with the general information entered by the user. .

In the above embodiment, the structure of the mark sheet having the functions of both the ID-dedicated mark sheet and the adjustment mark sheet and the structure in which both the general mark sheet and the adjustment mark sheet are provided in one mark sheet are shown. However, it is also possible to configure one mark sheet to have three functions of a general mark sheet and an ID-specific mark sheet adjusting mark sheet. In this case, one mark sheet can be configured by providing a user-written mark area, an ID mark area, and a precision reference mark area.

[0084]

As described above, according to the present invention, the adjustment recording medium on which the adjustment information used for adjusting the information reading sensitivity of the information reading processing device is recorded is stored in the information reading processing device. The adjustment recording medium is inserted into the information reading processing device because the information reading sensitivity of the information reading processing device is automatically adjusted or displayed based on the read output of the adjustment information read from the adjustment recording medium. Just by doing this, maintenance and adjustment of the reading section can be performed easily and in a short time without the need for specialized maintenance personnel.
The following effects are achieved. 1) The reading accuracy of the reading unit can be easily adjusted by anyone other than the maintenance personnel, and the reading accuracy can be maintained. 2) A maintenance-free reading device can be realized at low cost. 3) Since the reading accuracy of the reading device can be easily known, the reading unit can be adjusted during maintenance in a short time and without requiring a special jig.

Further, in the present invention, as the adjustment recording medium, both the area for recording the adjustment information used for adjusting the information reading sensitivity of the information reading processing device and the area for recording at least the predetermined input information. Since the mark sheet in which the area for recording the user identification information is formed is used, one mark sheet can be used.
The information reading sensitivity of the information reading processing device can be adjusted and predetermined input information can be input and the user can be identified, and the following effects can be obtained. 1) The cost of producing the mark sheet can be reduced because the mark sheet requires less artwork. 2) Mark sheet management becomes easier. 3) Since the reading sensitivity of the reading unit is automatically adjusted every time the user inputs information, maintenance is unnecessary.
