BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact and greatly reduced cost sheet reader.

[0002]

2. Description of the Related Art A conventional mark sheet reading apparatus is composed of a reading mechanism having a mark sheet sensor, a data processing mechanism using a personal computer, and a printer for printing and displaying the result of data processing. Was needed.

[0003]

Therefore, the configuration of the equipment becomes large and a large space is required.

This invention is intended to solve the above-mentioned drawbacks of the conventional mark sheet reading apparatus, and all the necessary mechanisms are housed in a one-box housing to make the apparatus compact and greatly reduce the cost. It is intended to provide a mark sheet reader.

[0005]

That is, the mark sheet reader of the present invention has a mark sheet insertion port, at least a printer I / F for a built-in printer, a serial communication I / F for data communication, and an operation display in a housing. A wiring board on which a control unit including an input / output I / F and a CPU is mounted, a mark sheet sensor substrate on which a sensor unit attached to a mark sheet insertion port is mounted, and a printing unit including a built-in printer are housed. An operation display unit is provided on the surface of the housing.

[0006]

According to the mark sheet reader of the invention,
By making the control unit a single board and storing all necessary mechanisms such as a printer in a one-box housing, the equipment has been made compact, eliminating the need for a large space and greatly reducing costs. Many can be introduced everywhere.

[0007] By attaching a sorter to the insertion opening of the mark sheet, a large amount of reading processing can be automatically performed.

Further, the data of the read result can be transmitted to an external host computer or the like by a serial communication I / F such as an RS-232C terminal for data communication, and the data of the read result can be managed. Of course, control from an external host computer or the like is also possible.

The details of the read result can be printed from the printer I / F using an external printer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a mark sheet reader according to the present invention will be described below with reference to the drawings.

FIG. 1 shows the basic configuration of a device.
1 except for the external printer 31
It is housed and fixed in a housing 1 consisting of a box. That is, the mark sheet 2 is provided on the side of the housing 1.
An insertion port 3 is formed, and a sensor unit 4 attached to the insertion port 3 is built in the housing 1.

The sensor section 4 has an optical sensor comprising a light emitting section 5 and a light receiving section 6 arranged facing the passage of the mark sheet 2 introduced from the insertion opening 3, and an optical sensor or the like formed as one board to form a mark sheet sensor. It is mounted on a substrate 7.

The sensor section 4 is connected to a control section 8 which is also formed as a single board. The control unit 8 includes at least a printer I / F 11 for the built-in printer 17, a serial communication I / F 12 for data communication, an operation display input / output
/ F13 and CPU 9 are built in and mounted on a wiring board. In the figure, a sensor unit 4 includes a monochrome level detection circuit 14 mounted on a wiring board, and an input I / F 15.
Is connected to the control unit 8 via the.

The printer I / F 11, the serial communication I / F 12, and the operation display input / output I / F 13 are respectively C
It is connected in parallel with the CPU together with the ROM and RAM attached to the PU 9. Reference numeral 16 denotes a printing unit having a printer 17 built in the housing 1, and a printer I / F 1
1 connected. An external printer 31 can be connected to the printer I / F 11. Reference numeral 18 denotes a backup battery for RAM.

A CPU having the ROM and RAM and I / Fs such as a printer I / F11 and a serial communication I / F12.
An operation display unit 21 is connected between F through an operation display input / output I / F 14. The operation display unit 21 includes an ON / OFF switch 22 for reading the correct answer, a display lamp 23 for displaying whether or not the reading has been performed normally, a correct answer pattern N
o. Enter the correct answer No. A switch 24, a scoring / confirmation mode switch 25 for obtaining a total scoring result and confirming a correct answer pattern, a reset switch 26, and a start switch 27 are provided.

The serial communication I / F 12 includes an RS-232C terminal for data communication, and transmits data of a read result to an external host computer or the like via an RS-232C connector to manage data of the read result. Is available. It also has a function of receiving control data of various scoring methods from an external host computer.

FIG. 2 shows a transport mechanism of the mark sheet 2. This transport mechanism is built in the housing 1 consisting of the one box, and has a first transport roller 41 provided with a driven roller (not shown) connected to the insertion slot 3 of the mark sheet 2; (Not shown) and a second transport roller 42 having a driven roller (not shown) connected thereto, and these are driven by a motor 44 via a timing belt 43 and the like.

Reference numeral 45 denotes a mark sheet detection sensor provided between the insertion slot 3 and the first conveyance roller 41. When the mark sheet 2 passes, the motor 44 is automatically driven to convey the mark sheet 2. . Further, an optical sensor 46 comprising the light emitting section 5 and the light receiving section 6 of the sensor section 4
Are disposed between the first transport roller 41 and the second transport roller 42. The optical sensor 46 composed of the light emitting unit 5 and the light receiving unit 6 is inclined so that the rear part thereof is lifted at an angle of 5 to 20 ° with respect to the mark sheet conveyance direction. This greatly improves the reading accuracy.

The operation display section 21 is shown installed on the upper surface of the housing 1 in the figure, and is not separate from the housing 1 consisting of one box.

The operation of the above mark sheet reader is as follows.
This will be described with reference to the flowcharts of FIGS.

First, the start switch 27 is input. Then, the correct answer reading mode switch 22 is input. Next, it is confirmed whether or not the reading mode switch 22 is turned on. By inputting the switch 24, a correct answer mark sheet is inputted from the insertion slot 3 of the mark sheet 2. If the mark sheet 2 is inserted normally, the O.D. The K lamp is turned on, and the correct answer pattern is printed on the built-in printer 17.
If there is an abnormality in the correct answer mark sheet 2, N.P. The G lamp is turned on, and the operation from the beginning is repeated again.

Next, when scoring or confirming the correct answer, the start switch 27 is input. It is checked whether the correct reading mode switch 22 is turned off, and the scoring / confirmation mode switch 25 is input. If it is in the scoring mode, the correct answer No. By inputting the switch 24, the mark sheet 2 to be graded is input from the insertion slot 3 of the mark sheet 2. If the mark sheet 2 is normally inserted, the O.D. The K lamp lights and the correct answer No. Is printed on the built-in printer 17. If there is an abnormality in the correct answer mark sheet 2, N.P. The G lamp is turned on, and the operation from the beginning is repeated again. When the scoring mode is not set, the correct answer No. After inputting the switch 24 to print the registered correct answer pattern, the operation from the beginning is repeated again.

[0023]

According to the mark sheet reader of the present invention, the equipment is made compact by making the control section one board and storing all necessary mechanisms such as a printer in a housing consisting of one box, so that it is wide. No space was required, and costs were significantly reduced, so that many could be installed anywhere.

Further, by attaching a sorter to the insertion opening of the mark sheet, a large amount of reading processing can be automatically performed.

Further, the data of the read result can be transmitted to an external host computer or the like by a serial communication I / F such as an RS-232C terminal for data communication, and the data of the read result can be managed.

The details of the read result can be printed from the printer I / F using an external printer.
