Description

The present invention relates to a slip printing apparatus such as a slip printer used by connecting to a POS terminal or the like.

[Prior art] As a slip printer that is connected to a POS terminal or the like and prints product sales data on delivery slips or credit slips, a slip sheet inserted into a paper insertion slot is sandwiched between a platen and a dot head. A dot printer that prints a slip by scanning a dot head in a direction perpendicular to the paper feed direction is employed. In this type of conventional slip printer, the dot head is stopped at the position where the slip printing is completed, so as to prepare for the next slip printing.

However, as shown in FIG. 3, the slip sheet generally has a configuration in which five to six sheets are overlapped and one end A thereof is bonded, and the opposite side B to the bonding end side, that is, the binding margin side A. Is turned up because it is not glued. Then, when such a slip sheet is inserted into the sheet insertion slot of the slip printer, the bonding end side, so-called binding side A, is used.
To the left side of the insertion slot, and the other side B, which is not adhered, to the right side of the insertion slot. Therefore, when the dot head is positioned at the right side of the paper insertion slot and stopped, the turned-up portion of the slip paper comes into contact with the ribbon guide of the dot head, and the printing operation is performed without the upper paper being inserted correctly. Was started, and the turned-up portion was caught in the dot head and a paper jam occurred. Conventionally, mechanical measures such as improving the shape of the insertion slot have been taken, but this is not sufficient, and the operator takes the best care to insert the slip sheet.

[Problems to be Solved by the Invention] As described above, a plurality of bound slip sheets formed by bonding one end of a plurality of sheets are sandwiched between a platen and a dot head, and the dot head is moved in the sheet feeding direction. In a conventional slip printing apparatus that prints slip data by scanning in the orthogonal direction, depending on the position of the dot head when inserting the slip paper into the paper insertion slot, the turned-up portion of the slip paper is a ribbon of the dot head. Since it is difficult to insert the paper into contact with the guide, and if the printing operation is started without the paper being inserted correctly, a paper jam may occur.

Accordingly, the present invention is to provide a slip printing apparatus which can easily insert a slip sheet having a plurality of sheets into the sheet insertion slot, can prevent a paper jam due to improper insertion, and can reduce the burden on the operator. It is.

[Means for Solving the Problems] The invention according to claim 1 of the present application is provided with a paper insertion slot through which a plurality of sheets are overlapped and one end of which is bonded and one end of which can be inserted, and this sheet is inserted. The adhesive end of the slip paper was aligned with one end of the insertion slot, and the slip paper was inserted into the paper insertion slot so that the adhesive end was substantially parallel to the paper feeding direction, and the slip was inserted into the paper insertion slot. In a slip printing apparatus that prints a slip by holding a slip sheet between a platen and a dot head and scanning the dot head in a direction perpendicular to the paper feed direction, after the initial processing performed in response to power-on and the slip It is provided with means for moving the dot head to one end of the paper insertion slot after printing is completed.

The invention according to claim 2 of the present invention is the invention according to claim 1 in which the dot head moved to one end side of the paper insertion slot is placed on the slip paper before the start of printing after the slip paper is inserted. Is added with means for scanning with no printing and no feed.

[Operation] With a slip printing apparatus employing such means, when inserting slip sheets of a plurality of sheets, the dot head moves to the bonding end side of the slip sheet, that is, the binding margin side. The turned-up portion on the opposite side does not come into contact with the ribbon guide of the dot head to make it difficult to insert, and it becomes easy to insert the slip sheet.

Prior to the start of printing of a slip, the slip sheet inserted into the sheet insertion slot is sandwiched between the dot head and the platen, and the dot head is scanned by no printing and no feed to the binding side of the slip sheet. Since the turned-up portion on the opposite side is extended, there is no danger that the upper sheet will be entangled by the subsequent sheet feed or scanning by the dot head, thereby preventing a paper jam.

Hereinafter, an embodiment in which the present invention is applied to a slip printer connected to a POS terminal will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a POS terminal, in which a CPU (central processing unit) 10 as a control unit has a built-in arithmetic circuit, a memory control circuit, etc. RO that stores programs to be executed
M11 and a RAM 12 having a memory for accumulating and registering product sales data and a memory for storing various data printed on a slip are controlled. Also, a keyboard circuit 14 for input processing of a key signal from a keyboard 13 provided with keys for inputting sales data of each sales product and keys for instructing start of slip printing, and a host computer and A communication interface 16 for performing data communication in a predetermined communication procedure through an in-line line 15 between
A display controller 18 for driving and controlling a CRT display 17 for displaying sales data and the like inputted from a keyboard 13, a drawer opening device 20 for a drawer 19 for storing cash and the like, and an RJ (receipt for printing on receipts and journals) / Journal) I / O port 23 that sends drive signals to the printer drive circuit 22 of the printer 21, and 24 that prints slips such as delivery slips and credit slips, and signal cables
Slip printer interface 2 connecting via 25
6, etc. are controlled by the CPU 10.

FIG. 2 is a front view of the slip printer 24. As shown in the figure, a paper insertion slot 31 into which the slip paper 30 is inserted is formed in the center of the housing, and the slip paper 30 inserted into the insertion slot 31 is provided with a dot head 32 provided above and near the insertion slot. And a platen 33 provided below, and is fed from the near side to the back side by a feed mechanism (not shown). Dot head 32 has an ink ribbon 34
And a scanning mechanism (not shown) scans the slip sheet 30 in a direction (left to right and right to left) orthogonal to the feed direction of the slip sheet 30 by a scanning mechanism (not shown). The insertion slot 31 is provided with a paper sensor 37 that optically detects, for example, that the slip paper 30 is inserted.

As shown in FIG. 3, the slip sheet 30 used in the present embodiment has a configuration in which five to six sheets are overlapped and one end A thereof is bonded, and the bonding end side is a binding table side. A
On the other hand, the opposite side B is turned up because it is not bonded. When the slip sheet 30 is to be inserted into the sheet insertion slot 31, the sheet is inserted with the bonding end side, so-called binding side A, on the left side of the insertion slot 31 and the unbonded opposite side B on the right side of the insertion slot 31.

The CPU 10 in the POS terminal is configured to execute the processing shown in the flowchart of FIG. 4 according to the program in the ROM 11 when the power is turned on. That is, when the flowchart is started in response to power-on, a predetermined initial process such as clearing the memory in the RAM 12 and clearing the I / O port 23 is performed as step (ST) 1.
Next, as ST2, a head movement command is sent to the slip printer 24 via the slip printer interface 26 so that the dot head 32 in the slip printer 24 is located at the left end when viewed from the front. Then the keyboard
It waits for key data to be input from 13 via the keyboard circuit 14, and when key data is input, executes key processing according to the type of the key.

Here, for example, when a print start key of a delivery slip is input as ST3, the print data of the delivery slip is edited from the data stored in the memory in the RAM 12 by various key processes up to that time as ST4. Next, as ST5, it is determined whether or not the slip sheet 30 has been inserted into the insertion slot 31 based on the output of the sheet sensor 37, and if it has not been inserted, it waits until it is inserted. Then, when the slip sheet 30 is inserted into the insertion slot 31, one line of space data is edited as ST6, and set to the slip printer 24 via the slip printer interface 26. Next, 1 as ST7
Slip printer 24
Send to

Thereafter, as ST8, a feed command of the number of lines determined according to the slip type is transmitted to the slip printer 24,
The slip print processing is executed based on the print data edited as 9. When a predetermined slip printing process is completed in ST10, a head movement command is sent so that the dot head 32 of the slip printer 24 is located at the left end when viewed from the front in ST11, and waits for input of key data from the keyboard 13. .

The slip printer 24 of the present embodiment thus configured
In response to the power on, the dot head 32 moves to the left end when viewed from the front and stops. Also, when one slip printing process is completed, the dot head 32 similarly moves to the left end when viewed from the front and stops. Therefore, the slip form 30
Since the dot head 32 is always positioned on the binding side A of the slip sheet 30 when the sheet is inserted into the paper insertion slot 31, the portion where the sheet on the opposite side B is turned up with respect to the binding side A is a dot. The insertion does not become difficult due to contact with the ribbon guide 35 of the head 32, and the insertion can be performed correctly without special attention of the operator. Therefore, it is possible to avoid a situation in which the printing operation is started without the correct insertion and a paper jam occurs as in the related art, and the burden on the operator is reduced.

When a key for starting printing of a slip is input, it is confirmed that the slip sheet 30 is inserted into the insertion slot 31, and then the platen 33 moves upward to shift the slip sheet 30 to the dot head 32.
And the platen 33, and in this state
The dot head 32 scans one line from the left end to the right end without printing without feeding 30. Thereafter, the paper is fed according to the slip type, and the slip printing process is started. Therefore, before starting printing the slip, print the dot head
The sheet 32 moves from the binding side A to the opposite side B while pressing the slip sheet 30, and extends the turned-up portion of the opposite side B. There is no danger that the turned up portion of 30 will be taken up by the dot head 32.

In the above embodiment, an embodiment in which the present invention is applied to a slip printer has been described. However, it goes without saying that the present invention can be applied to, for example, an RJ printer or the like as long as it can print a slip. In the above-described embodiment, the case where the dot head 32 is moved to the left as viewed from the front of the slip printer has been described.
This is because the binding side A is located on the left side when inserting
When positioning the dot head 32 on the right side according to the specifications of the printer, it is needless to say that the dot head 32 is moved to the right side.

[Effects of the Invention] As described in detail above, according to the present invention, even if a slip sheet is a plurality of sheets, it is easy to insert the slip sheet into the sheet insertion slot. A slip printing device that can reduce the burden can be provided.

According to the second aspect, the slip printing operation is started after the turned-up portion of the slip sheet is stretched.
This eliminates the possibility that the dot head winds up the turned-up portion of the slip sheet due to the paper feed or the scanning of the dot head.
