FIELD OF INDUSTRIAL APPLICATION The present invention relates to a printer for recording a bankbook, and more particularly, a magnetic stripe reader/writer section formed separately, a control section for controlling the printing function of the printer, and a bankbook printer. The present invention relates to a deposit passbook entry printer suitable for a portable passbook entry terminal, which is configured to be portable by storing the entry printer in one carrier.

0002

[Prior Art] In recent years, automatic cash deposit and withdrawal systems (hereinafter referred to as
With the spread of ATMs, most cash deposits and withdrawals from financial institutions are now carried out using ATMs.

[0003] However, in order to use an ATM, the user must go to the ATM installation location, and for those who have difficulty going to the ATM installation location, it is difficult to make deposits and withdrawals at any time. The inconvenience is that it cannot be done. There is also a method in which a financial institution staff member performs procedures such as deposits and withdrawals on behalf of the user, but in this case, the staff member goes to the user's location, receives the bankbook, and takes it back to the ATM. The user has to go through procedures for deposits and withdrawals, record books, and then deliver the completed bankbook to the user, which is extremely inconvenient.

In order to eliminate such inconvenience for both users and financial institutions, as shown in FIG. 23, a reader/writer section 1 is provided which exchanges data with a magnetic stripe formed on the cover of a bankbook. It is a combination of a control unit 2 that has a communication function with a host computer and a printer unit 3 that prints transaction details on a bankbook, and is carried by a financial institution staff member to a location designated by the user for deposits and withdrawals. Portable passbook entry terminals that can perform such procedures are being researched.

[0005] Conventional printers for deposit passbook recording, such as A
The printer section of the TM is not equipped with a device for detecting slippage of the bankbook.

[0006]

[Problems to be Solved by the Invention] By the way, in a printer for recording a deposit passbook, if slippage occurs between the passbook transfer device and the deposit passbook, the print head cannot be correctly positioned on the designated line of the deposit passbook. This causes serious inconveniences such as predetermined items not being printed on the bankbook. If such an inconvenience occurs at an ATM installed at a financial institution's counter, an attendant is on standby at the counter and the necessary documents, such as a new bank passbook, are available, so the problem can be dealt with immediately. However, if such an inconvenience occurs with a portable passbook entry terminal, it will require a great deal of effort to recover from it. Therefore, in a printer used for a portable passbook entry terminal, how to detect slippage of a deposit passbook is an important technical issue. Furthermore, because the deposit passbook entry printer used in the portable passbook entry terminal is strongly required to be smaller, thinner, and lighter due to its nature, the slip detection means is configured to be as compact as possible. must be done.

The present invention has been made to solve the problems of the prior art, and it is an object of the present invention to provide a printer that is compact and equipped with highly reliable slip detection means.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a platen roller and a printing device arranged vertically opposite to each other, and a deposit inserted between the platen roller and the printing device. In a deposit passbook recording printer equipped with a passbook transfer device that horizontally transfers a passbook, a rotation amount detection device that detects the amount of rotation of the platen roller that rotates in response to the transfer of the deposit passbook is provided in parallel with the platen roller. The central axes of these platen rollers and the rotation shaft of the first rotation amount detection device are connected via a power transmission mechanism, and the transfer amount of the bankbook determined from the output value of the rotation amount detection device and the first rotation amount detection device are connected. Comparing the transfer amount of the deposit passbook determined from the rotation amount of the motor that is the power source of the passbook transfer device, detecting the presence or absence of slippage of the deposit passbook with respect to the passbook transfer device or the amount of slippage, and determining whether slippage has occurred. When the amount of slippage exceeds a predetermined value, the transfer of the deposit passbook is automatically stopped.

[0009]

[Operation] By arranging the platen roller and the rotation amount detection device in parallel and connecting them via a power transmission mechanism, the width of the printer can be made smaller than when the rotation amount detection device is provided at the shaft end of the platen roller. I can do it. In addition, by detecting slippage of the deposit passbook against the passbook transfer device and automatically stopping the transfer of the deposit passbook, printing errors on the deposit passbook can be prevented and the reliability of the printer can be increased. can.

, 156 are provided.

[0038] Hereinafter, a bankbook 15 using the printer described above will be described.
The bookkeeping procedure in step 1 will be explained.

First, prior to printing, the reader/writer unit 1 reads data such as the owner's PIN number, printed pages, and printed lines from the magnetic stripe 152 formed on the bankbook 151, and operates the control unit 2. and communicates the data along with the PIN number to the host computer.

[0040] Once the necessary operations such as verifying the password are completed, printing begins.

That is, the engagement between the hook member 142 and the lock pin 16 is released, and the upper frame 12 is erected about the mounting shaft 81 as shown in FIG. In addition, Figure 1
In this case, the upper frame 12 is erected at only about 45 degrees with respect to the lower frame 11, but in reality it is erected at more than 90 degrees and is stably held on the lower frame 11. At this time, the clamper 28 is at the position closest to the platen roller 15, that is, the initial setting position, and the first clamping member 31 and the second clamping member 33 are closed. The third sensor 85 detects that the clamper 28 is at the initial setting position.

The presence or absence of the deposit passbook 151 is detected by the first sensor 83, and it is confirmed whether the deposit passbook 151 is properly clamped.

Next, the stepping motor 72 rotates by a predetermined amount according to the control program stored in the control unit, and the heating unit of the print head 101 prints the next line of the printed line recorded on the magnetic stripe of the bankbook read in advance. Move the bankbook so that it matches 106. At this time, the rotation amount of the platen roller 15 is detected by the rotary encoder 21, and the control unit 3 connected to the printer via the signal line
The transfer amount of the deposit passbook 151 determined from the output value of the rotary encoder 21 and the rotation amount of the stepping motor 72 are determined by the computer.
is compared with the transfer amount, and it is determined whether or not there is slippage between the platen roller 15 and the bankbook 151, or whether the amount of slippage is greater than a predetermined value.

If there is no slippage, or if the amount of slippage is less than a predetermined value, it means that the designated line and the heating section 106 of the print head 101 match, so the control unit Predetermined printing is performed according to a control program stored in the printer. If there is slippage exceeding a predetermined value, the stepping motor 72 is automatically stopped according to a control program stored in the control unit.
Also, the printing operation is automatically stopped. The operator can repeat each of the above operations after performing necessary repairs such as wiping the surface of the platen roller 15.

When printing is completed up to the 12th line of the upper page 153, the clamper 28 reaches the set position of the fourth sensor 86, and it is detected that the clamper 28 has been moved to the end portion. Then, the control unit displays that printing up to the 12th line of the upper page 153 has been completed.

When the staff member opens the upper frame 12, the fifth sensor 87 detects this fact. Then, the clamper 28 returns to the initial setting position after a predetermined time according to a control program stored in the control section. Therefore, the clamper 28
The bankbook 151 can be taken out from the clamper 28 by operating the operating member 32 and opening the first clamping member 31 and the second clamping member 32.

When recording on the lower page 154 of the bankbook 151, the feed plate 17 is housed in the lower frame 11 and set in the state shown by the two-dot chain line in FIG.

Next, as shown in FIG.
The lower side 154a of the lower page 154 of 1 is abutted against the second positioning protrusion 24 erected on the front edge of the lower frame 11, and the upper page 153 of the bankbook 151 is moved between the first clamping member 31 of the clamper 28 and the second positioning protrusion 24. It is inserted between the clamping member 33 of. Thereafter, the operating member 32 of the clamper 28 is rotated in the closing direction, and the first clamping member 31 and the second clamping member 33 clamp the bankbook 151.

Next, when the upper frame 12 is closed and the staff operates the control unit 2 to instruct the start of printing, the stepping motor 72 rotates a predetermined amount according to the control program stored in the control unit, and the power transmission mechanism 71 is rotated. The clamper 28 is moved in the depth direction together with the bankbook 151 through the
After that, it will stop temporarily. Then, the second sensor 84 detects the presence or absence of the deposit passbook 151, and the second sensor 84 detects the presence or absence of the deposit passbook 151.
1 is clamped in a normal state.

Thereafter, printing from the 13th line to the 24th line can be performed in the same manner as described above.

[0056] The printer of the above embodiment can print the bankbook 151.
Since the clamper 28 is used as a transfer device, by using the strong spring member 34, the print pages can strongly clamp the deposit passbooks 151 having different paper thicknesses. Furthermore, since the rubber plates 40 and 64 are attached to the inner surfaces of the first and second clamping members 31 and 33, the clamping members 31 and 33 are
, 33 and the bankbook 151. Therefore, the deposit passbook 151 pressurized by the platen roller 15 and the print head 101 can be reliably transferred. Furthermore, compared to the case where a roller is used as a passbook transfer device, the clamper 28 itself can be made thinner, and the power transmission mechanism 71 can be arranged horizontally, so the printer can be made thinner. can. Furthermore, since the clamper 28 is driven within a range that allows printing on half a page of the bankbook 151, the overall length of the printer can be shortened.

Furthermore, since the feed plate 17 is configured to be housed within the lower frame 11, the printer can be made smaller. Since the feed plate 17 is provided with the first positioning protrusion 23 and the second positioning protrusion 24, the upper page 1
53 and the lower page 154, the deposit passbook can be positioned with reference to the feed plate 17, so that it is easy to use.

The printing device 95 also includes a platen roller 1.
5, a rotating member 104 that orients the print head 101 in the tangential direction of the platen roller 15, and a tension spring 10.
5, the heating section 106 of the print head 101 can be kept in close contact with the platen roller 15 directly above the platen roller 15 at all times. In addition to this, the printed part is overwritten twice,
Moreover, since the heating time of the ink ribbon 131 is controlled according to the outside temperature, high-quality printing can be performed.

Furthermore, since a 1 dot/line thermal line dot type print head is used as the print head, the printing device can be made smaller and thinner. Also,
A preset computer program slows down the feeding speed of the bankbook 151 in the printing section where data is actually printed, and transfers the deposit to the non-printing section, such as the printed section where data has already been printed or the space between lines between prints. Since the feeding speed of the passbook 151 is increased, high-quality printing can be performed with high efficiency. Furthermore, since the effective printing digits of the line head are divided into a plurality of parts and only the digits necessary for printing are energized, power consumption can be reduced.

Furthermore, since the ink ribbon 131 is transported approximately equal to the amount of rotation of the platen roller 15,
The same character data printed on the bankbook 151 can be left on the ink ribbon 131 and can be used as reference material at a later date. Further, since the rotation of the platen roller 15 is transmitted to the ink ribbon take-up shaft 133 via the gear mechanisms 22, 135, and 136, power can be transmitted reliably. Therefore, ink ribbon 1
31 and the deposit passbook 151, and the deposit passbook 151 is not easily soiled. Further, since the detecting portion 137 is provided protruding from the ink ribbon cartridge 96, the opening/closing of the upper frame 12 and the attachment/non-attachment of the ink ribbon cartridge 96 can be detected by one sensor 87.

Furthermore, since the amount of rotation of the platen roller 15 is detected by the rotary encoder 21 and compared with the amount of rotation of the stepping motor 72, the amount of rotation of the bankbook 15 is detected.
It is possible to easily check whether or not 1 has been transferred reliably, and erroneous printing can be prevented.

In the above embodiment, the transfer control of the deposit passbook corresponding to the detection of slippage and the presence or absence of slippage is installed in the control unit 3 which is formed separately from the printer and is connected to the printer by a signal line. Although this was done using a computer with a similar control program stored therein, it is also possible to install a computer in the printer itself.

Further, in the embodiment described above, a rotary encoder is used as a rotation amount detection device for the platen roller 15, but other known rotation amount detection devices such as a volume can also be used.

Furthermore, the gist of the present invention relates to the detection of slippage that occurs between the platen roller and the bankbook, and other parts than the gist of the present invention are not limited to the above embodiments. It can be designed arbitrarily. For example, as shown in FIG.
The other end of 73 may be removably connected with a hook 174. Further, as shown in FIG. 22, a plate-shaped clamping member 17 whose one side in the longitudinal direction is rotatably connected
5, 176 may be pressed by a spring member 177 so as to be openable and closable. In addition, any other configuration can be adopted.

[0065]

[Effects of the Invention] As explained above, according to the present invention,
Since the platen roller and the rotation amount detection device are arranged side by side and connected through the power transmission mechanism, the width of the printer can be made smaller than when the rotation amount detection device is provided at the shaft end of the platen roller. In addition, slippage of the deposit passbook against the passbook transfer device is detected and the transfer of the deposit passbook is automatically stopped, making it possible to prevent printing errors on the deposit passbook and improve the reliability of the printer. I can do it.
