Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to a one-way form monitoring device, and more specifically, to a device for processing forms, such as an optical character reading device, for ejecting processed forms. The present invention relates to a form monitoring device that monitors the status.

[Technical background of the invention]

For optical character reading devices, etc., in order to facilitate the classification and organization of processed forms, two sets of sukkatsuka (where processed forms are to be ejected) are prepared, and a form that has been correctly processed and a form that has been processed correctly are prepared. It is common to have equipment for separating and discharging incomplete forms into the stacker. In recent years, the reading speed of optical character reading devices has become faster, and an increasing number of devices are capable of starting reading the next form before the previous one read is delivered to the stacker. In optical character reading devices that can process forms continuously in this way, errors occur when a specified form is not ejected to a specified stacker for some reason (specific examples include If the form is ejected to the stacker that cannot be read correctly, the case may be the opposite of the above case.■ The form may not be ejected to any stacker and stays in the conveyance path.) It is necessary to prepare a means for knowing how many sheets to return from which stacker to which stacker in case this occurs. Conventionally, methods A and B below have been used to achieve this objective. A: Each time a correct reading process is completed, a consecutive number is assigned to the form, and when an error occurs, the system searches for the missing number from the stacker (hereinafter referred to as the reading system stacker) where forms that have been correctly read are ejected. Alternatively, the stacker (which
A method of searching for a numbered form from a reject stacker (hereinafter referred to as a reject stacker), and an equivalent method. B. A method in which the read contents are displayed on a display and the operator finally identifies the ejected form. [Problems with the Background Art] The above method has the drawback of requiring the addition of mechanical parts for numbering, leading to an increase in production costs. Furthermore, method B described above has the disadvantage that the burden on the operator and the loss of time due to the reference sign become large. [Object of the Invention] The present invention was made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a form monitoring device that can easily notify an operator of a form ejection error using simple equipment. [Summary of the Invention] According to the present invention, monitoring information indicating the result of reading a form (this monitoring information is information that distinguishes whether correct reading was performed or incorrect reading was performed). In addition to adding information from the t-reading processing circuit to the monitoring circuit, sensors are installed at the entrances of the reading system stacker and rigid stacker to detect the addition of forms, and the output of each sensor is compared with the information added from the reading processing circuit to the monitoring circuit. The display of a display circuit such as a light emitting diode is controlled according to the comparison result.

0 indicates a monitoring circuit, and 11 indicates a display circuit. First, the forms 1 stored in the hopper 2 are sent out one by one to the conveyance path 3 by a feed roller (not shown), and are conveyed on the conveyance path 3. When the form 1 reaches the reading head 4, the form image is converted into a binary signal by the reading head 4 and applied to the reading processing circuit 7. The reading processing circuit 7 reads the characters written on the form by processing the binarized form image, and a control signal CI corresponding to the reading result is added to the drive circuit 8 and sent to the next form. Start processing. Note that here, as a result of the reading processing circuit 7 processing the form,
When all the characters written in one form can be read, the control signal C4 becomes H(f(-/IV),
If there is a character that cannot be read among the characters written in one document, the control signal C1 becomes L (1, low level). When the control signal C4 is applied in this way, the drive circuit drives the select gate 9 at a predetermined timing to determine where the form is to be discharged. That is, the drive circuit 8 receives the control signal C1
When the control signal is H, the select gate 9 is driven so that the form is ejected to the reading stacker 5, and when the control signal is L, the form is ejected to the reject stacker 6. Sensors S1 and S2 are provided at the entrances of the reading stacker 5 and the reject stacker 6, respectively.

The display circuit 11 is controlled based on the comparison result. FIG. 2 shows an example of the circuit configuration of the monitoring circuit 10 and the display circuit 11. In the illustrated embodiment, the monitoring circuit 10 includes six D-type flip-flops F1 to F4.
The display circuit 11 is composed of four exclusive OR gates (output negative logic) E1 to E4, and the display circuit 11 includes four switching transistors TriNTr4 and a light emitting diode Dt''h.
It consists of In this embodiment, the flip-flops F1 to F6 are arranged in two stages, but this is done in consideration of the possibility that after an error occurs, the next form will be processed many times and then ejected.
If the processing speed of the reading processing circuit 7 is fast, the number of stages of flips 70 will further increase. Here, to define the terms used below, the first timing means the timing at which the processed form is first discharged based on a predetermined timing, and the second timing means the timing at which the processed form is discharged at the first timing and the fcl limit. It means the timing at which the next form is output. This timing is maintained by a gate CK commonly applied to all seven lip-flops F--F6. The monitoring information @C2 outputted from the reading processing circuit 7 is first held in the flip-flop F1, and then held in the 7th flip-flop Fz at the next clock CK. Therefore, when the flip-flop F2 indicates Ht-, it indicates that the form ejected at the first timing should be stored in the reading stacker 5, and when the flip-flop F2 indicates Lft, the form ejected at the first timing is rejected. Indicates that it should be stored in the stacker 6. Also, at the second timing, when the flip-flop F1 indicates Hi, it indicates that the ejected form should be stored in the reading stacker 5, and when the flip-flop F1 indicates L=i, the ejected one-column form is stored in the reading stacker 5. Indicates that it should be stored in the reject stacker 6. Further, the detection signal AtU output from the sensor It'i is first held in the flip-flop ps, and then held in the 7-lip-flop R in the next clock 4. Therefore, when the flip-flop tile indicates H, it indicates that the form ejected at the first timing is stored in the reading stacker 5, and when the flip-flop h indicates Li, the form ejected at the first timing is stored in the reading stacker 5. Indicates that k is not stored in . Also, at the second timing, flip-flop b becomes H.
=i indicates that the ejected form has been stored in the reading stacker 5, and when the flip-flop b indicates Ltl-, it indicates that the ejected form has not been stored in the reading stacker 5. Further, the detection signal outputted from the sensor S2 is first held in the flip-flop F11, and then held in the flip-flop F@ at the next clock xX timing. Therefore, when the flip-flop h indicates H, it indicates that the fc form was ejected at the first timing and was stored in the reading stacker 5, and when the flip-flop pi indicates L, it indicates that the fc form was ejected at the first timing and stored in the reading stacker 5.
This indicates that the form ejected at the timing was not stored in the reject stacker F. Further, when the flip-flop FφEl-I't- indicates that the form ejected at the second timing is stored in the reading stacker 6, when the flip-flop F1 indicates L=i, it indicates that the form ejected at the second timing is stored in the reading stacker 6. This indicates that it has been stored in the shift stacker 6. The contents of these flip-flops F1-F@ are compared by exclusive OR gates h-m, and the light emission state of the light-emitting diodes H-m is controlled based on the comparison result, and the operator is informed of the ejection status of the form. That is, exclusive OR gate Fa is connected to flip-flop F2.
Depending on the comparison result of F4, switching transistor Tr
The exclusive OR gate & controls the base current of the switching transistor Trt according to the comparison result of the flip-flop F%Fk. As a result, the switching transistors Trt·Tr! The continuity is determined, and therefore the operator can know the storage status of the form to be discharged at the first timing based on the combination of the light emitting states of the light emitting diodes DIDω. Also, exclusive OR gate IC, /i flip-flop F
Based on the IFA comparison results, the switching transistor 'f
The exclusive OR gate & controls the base current 1 of the switching transistor Tr according to the comparison result of the flip-flop FsFs. Therefore, the operator knows the storage status of the form to be discharged at the second timing based on the combination of the light emitting states of the light emitting diodes D3D. There are 24, ie 16, combinations of the light emitting states of the light emitting diodes Di/%/D, but when considered separately for the first timing and the second timing, there are 4 combinations each. Therefore, here, we will consider only the first timing: light emitting diode DID! There are four combinations as follows. Case: When the light emitting diode DIDI is both H, Case 2: When the light emitting diode Ds is H1, when the light emitting diode D2 is L, Case 3: When the light emitting diode D1 is L1, when the light emitting diode D2 is L (, Case 4...Light-emitting diode D+p (when both are L, flip-flop P4F, , both become H,
That is, since it is impossible for the form ejected at the first timing to be stored in both the reading stacker 5 and the reject stacker 6, the fringe float F2F4 in case 1 is
The combinations of Fg are shown in Table 1. Therefore, when the combination of light emitting diodes D and Dω is in case 1, the operator realizes that the form that should have been ejected to the reject stacker 6 at the first timing has stopped on the conveyance path 3 without being stored in any of the stackers. Know that. Next, the combinations of flip-flops F2F and F in Case 2 are as shown in Table 2. In case 2, 1 is a case where the correctly read 1@ form is stored in the reading system stacker 5, and in case 2, 2 is a case where the incorrectly read form is stored in the reject stacker 6.
This is the case when it is stored in Therefore, the light emitting diode Th-
When the combination of Th is case 2, the operator knows that the form ejected at the first timing is stored in the original stacker. Next, the combinations of flip-flops F4FJk in Case 3 are as shown in Table 3. Case 3 in Table 3 is a case in which a correctly read form is stored in the reject stacker 6, and Case 3 in 2 is a case in which a correctly read form is stored in the read system stacker 5. Therefore, the light emitting diode D1・D
! When the combination is case 3, the operator knows that the single stacked ticket ejected at the first timing was erroneously stored in another stacker. Next, the combination of 7 lip-flops Fz PsFa in case 4 is as follows. This case 4 is a case where a correctly read form is not stored in any stacker and remains on the conveyance path 3. Therefore, when the combination of light emitting diodes DI"D2 is case 4, the operator knows that a correctly read form is stopped on the conveyance path 3. Furthermore, when the combination of light emitting diodes D3 and D2 is in case 4, the operator knows that a correctly read form is stopped on the conveyance path 3. The storage status of the documents that should be stored is the same as the case classification described above, although the explanation will not be repeated. Note that although specific circuit examples of the monitoring circuit 10 and the display circuit 11 have been shown above, variations of equivalent circuits are possible. Needless to say, it is possible to perform the same function with regard to the monitoring circuit 1O. (Effects of the Invention) As explained above, according to the present invention, a very simple operation can be performed. The circuit allows the operator to be informed of the storage status of the forms.
