In the present invention, the length of the booklet is determined based on a detection signal from a detector provided on a conveyance path of the booklet such as a passbook, and printed on a non-printing area of a binding of the booklet. The present invention relates to a booklet printer device that controls a conveying unit and a printing unit so as not to cause the printing unit to perform the operation.

[0002]

2. Description of the Related Art The present applicant has filed a Japanese Patent Application No. Hei.
In the specification of the issue, the distance D from the trailing end detector provided at the insertion / ejection opening of the booklet to the print head is defined as the total length L of the spread booklet of the standard size and the width of the non-printing area of the binding. W is equal to or greater than half of the sum of the print pitch P, that is, the conditional expression D ≧ (L + P +
W) A setting is made so as to satisfy 先端 2, and a leading end detection signal from a leading end detector of a booklet provided immediately before the print head, a trailing end detection signal from the trailing end detector, and a carry amount are set. A length indexing means for calculating the length of the booklet on the basis of the length of the booklet, and a correction value set based on the difference between the distances between the two detectors provided in the printer device. Before the non-printing area reaches the position facing the print head, the length of the booklet is determined in the middle of the printing conveyance, and the non-printing of the binding of the booklet is performed. A booklet-type printer apparatus is disclosed in which an area is determined, and the transporting means and the printing means are controlled so as not to print on the non-printing area.

[0003] With the above structure, when taking in booklets,
In other words, without performing any special processing to determine the length of booklets before starting the printing process, the length is calculated and indexed during printing transport, shortening the transport path, The time has been reduced.

[0004]

However, in the above prior art, as described above, the distance D from the trailing end detector to the print head is determined by the total length L of the double-page spread of standard size booklets and the binding position. It is set to be equal to or greater than one half of the sum of the width W of the non-printing area and the printing pitch P, and is obtained from the leading edge detector and the trailing edge detector in the forward conveyance of the booklet. Since the length of the booklets is calculated based on the detection signal and the transport amount, the total length L 'in the double-page spread state is obtained.
Is larger than the standard size such that (L ′ + W + P) ÷ 2> D, but before the non-printing area reaches the position facing the print head, that is,
Since the length of the booklets could not be calculated and indexed during printing conveyance, the booklet length was determined to be abnormal and could not be used. In order to enable the use, it is necessary to lengthen the D, and therefore, the longer the maximum length of the booklet, the longer the transport path of the booklet, the larger the depth dimension of the device, There was a problem that the purpose of was not achieved.

In view of the above, in the present invention, the distance from the trailing edge detector to the print head is determined by calculating the sum of the total length of the spread state of the standard size booklet, the width of the non-printing area of the binding, and the printing pitch. Set to be equal to or greater than one half, and insert the booklet with the leading edge detection signal from the leading edge detector of the booklet provided immediately before the print head when the booklet is transported by the transport means. A length determining means for calculating the length of a booklet based on a trailing edge detection signal from a trailing edge detector provided at the discharge port and a transport amount by the transporting means, and a length of the indexed booklet; Length correction means for correcting the length of the booklet using the correction value set by the difference between the distances between the two detectors of the printer device, and calculating the length of the booklet during the printing conveyance to perform non-printing. Determine the area to prevent printing in the non-printing area of the booklet binding. By controlling the conveying means and the printing means, shortening the conveying path, in a booklet printer device aimed at miniaturization of the printer device, by devising the transport control and length indexing method of the booklet, It is intended to be able to handle booklets whose length is larger than the standard size.

[0006]

In order to solve the above-mentioned problems, the present invention provides a distance D from a trailing edge detector to a print head.
Is set to be equal to or greater than half the sum of the total length L of the double-page spread of the standard size booklet, the width W of the non-printing area of the binding and the printing pitch P, and Along with the transport of the booklet, a leading edge detection signal from the leading edge detector of the booklet provided immediately before the print head, a trailing edge detection signal from the trailing edge detector provided at the insertion / ejection port of the booklet, and the transporting means. Length determining means for calculating the length of the booklet based on the transport amount of the printer, and correcting the length of the indexed booklet by the difference in the distance between the two detectors of the printer device. Providing length correction means to correct using the value, determine the length of the booklet in the middle of the print transport, determine the non-print area,
In a booklet printer device configured to control the transport unit and the printing unit so that printing is not performed on the non-printing area of the booklet binding, in the booklet printer device, the transport control unit that controls the transport unit is configured to transport in a forward direction. ｛L- (W
+ P) If the trailing edge detector has not yet detected the trailing edge of the booklet when the line of $ 2 is at the position facing the print head, the trailing edge detector will detect the trailing edge of the booklet. After the transport is continued until the detection, the booklet is transported in the reverse direction until the initially designated print line faces the print head.

[0007]

When print information (designated data of a line to be printed and print data) is received from a host computer and insertion of a booklet is detected, the transport means takes in the booklet from the insertion slot and transports the booklet toward the print head. . Since the front end of the booklet is detected by the front end detector, the position of the front end of the booklet with respect to the print head can be determined. However, at this time, since the total length of the booklet cannot be determined, the printer apparatus assumes that the line to be printed received from the host computer is on the upper page, stops the transporting means at that position, and stops the platen. After setting the gap, the received print data is printed on a booklet by the printing means.

[0008] The line of {L- (W + P)} / 2 in the booklet
If the trailing edge of the booklet is detected by the trailing edge detector when it reaches the position facing the print head, the booklet length indexing means determines the transport amount from the leading edge detection to the trailing edge detection (pulse to the transport motor). The length of the booklet can be calculated from the number) and calculated. The difference (machine difference) between the indexed length and the length indexed by transporting booklets of a standard size in advance is corrected by the correction value stored in the correction value storage means, and The correct length is obtained, and the non-print area is determined based on this.

In this way, the length of the booklet is determined in the process of processing the line to be printed received from the host computer, and whether the page is the upper page or the lower page is recognized, and the non-print area can be calculated. Therefore, even if the length of the booklet is unknown when the line to be printed reaches the position facing the print head, the length of the inserted booklet is calculated and divided during the printing process and transport. It does not require special handling of booklet length. If it is determined that the line to be printed is on the lower page, the sheet is conveyed to the designated print line on the lower page, the conveying means is stopped, the platen gap is set, and the print data is printed on a booklet.

On the other hand, {L- (W + P)} of booklets
If the trailing edge of the booklet is not detected by the trailing edge detector when the / 2 line reaches the position facing the print head,
The transport control means causes the booklet to be transported in the forward direction until the trailing edge detector detects the trailing edge of the booklet, and stops the transport if the trailing edge is detected, during which the booklet is moved to the leading edge detector. The total length is calculated using the number of pulses given to the transport motor from the time of detection of the front end to the time of detection of the rear end of the rear end detector, and
After the correction using the correction value, the booklet is conveyed in the reverse direction by the same number of pulses, and the booklets are returned to the original position. As a result, the length of a long booklet can be determined, and accordingly, a long booklet can be printed on a predetermined line in the same manner.

If the number of print lines received is so large that the upper and lower pages are straddled, the trailing edge detector detects the trailing edge during printing of the upper page. Since the non-printing area between the lower page and the lower page can be calculated, printing is performed up to the last line of the upper page, the non-printing area of the booklet binding is transported to the first line of the lower page without printing, and the transport is stopped. After setting the platen gap, the received print data is printed.

When printing is completed, the transport direction of the booklet is reversed, the transport is performed in the direction of the insertion slot, and the booklet is awaited. When the removal is detected by the rear end detector, a series of processing ends.
