Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a printer using long feed paper.

[Prior Art] For example, in an electronic cash register, product sales data input from an input section is cumulatively registered in a memory, displayed on a display, and printed out on receipt paper and journal paper by a receipt/journal printer. There is.

The receipt paper and journal paper used in this register are roll-type long papers, and the receipt paper is cut and handed to the customer, while the journal paper is wound up internally.

By the way, the leading edge of receipt paper is not neatly cut, so when it is set, the leading edge is fed and cut with a cutter to trim the paper. Also, journal paper, for example, will be taken out when the registration for -day is completed and payment is made, and a new paper will be set, but at this time, if the paper is still in the middle, it must be completely wound up before being taken out. That's what I do.

Additionally, if receipt paper or journal paper becomes sagging during use, the paper is fed to correct the sag.

For this reason, conventionally, as shown in FIG. 6, one-contact switches 1 and 2 are provided to feed receipt paper and journal paper, respectively, and when these switches 1 and 2 are turned on,
The off signal is read by the CPU 4, which operates based on program data in the ROM 3.

When the CPU 4 reads the ON state of the receipt feed switch 1, the drive circuit 5 is controlled and the motor 6 is rotated to feed the receipt paper.
When turned on, the drive circuit 7 is controlled to rotate the motor 8 and feed the journal paper.

[Problem 8 to be solved by the invention] However, if there is only one type of paper feed speed as described above, the speed must be adjusted to a relatively slow speed to correct the slack, and for this reason, the receipt paper must be When feeding or winding up journal paper, there was a problem that the feeding was too slow and took a long time.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a printer that uses a switch having multiple contacts, changes the feed speed of paper depending on the on/off state of each contact, and can set the feed speed according to the purpose. be.

[Means for Solving the Problems] The present invention provides a switch having a plurality of contacts for feeding the paper, and an on/off switch for each contact of the switch in a printer that prints data on a long feed paper. A feed control means is provided to control the paper at different speeds depending on the state.

[Function] In the present invention having such a configuration, the speed at which the paper is fed changes by operating the switch so that each of its contacts is in a different on/off state. Therefore, the paper feed speed can be set according to the purpose.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, the present invention will be described as applied to a receipt/journal printer used in an electronic cash register.

FIG. 1 is a diagram showing the external appearance, and 11 is a rate issuing port, 12 is a journal inspection window, 13 is a power switch, 14 is a receipt feed switch, and 15 is a journal feed switch.

Inside the receipt issuing port 11, a roll-type long receipt paper, a feed mechanism for feeding the receipt paper, a receipt printer, a cutter, etc. are housed.
Further, inside the journal inspection window 12, a roll-type long journal paper, a feed mechanism for feeding the journal paper, a winding roller for winding the paper, and a journal printer are housed.

FIG. 2 is a circuit diagram showing the main circuit configuration, where 21 is a CPU constituting the main body of the control section, and 22 is a ROM in which program data for the CPU 21 to control each section is stored.

The CPU 21 includes the receipt feed switch 14.
And a switch operation signal from the journal feed switch 15 is input.

The receipt feed switch 14 is a pushbutton type switch provided with a first contact 14a and a second contact 14b, and when the suppressing member 14c is lightly pushed, the first contact 14a turns on.
When pressed strongly, both the first contact 14a and the second contact 14b are turned on. Each contact 14a, 1
The on/off signal of 4b is used as a switch operation signal by the above-mentioned C
It is now being manually operated by PU21.

Further, the journal feed switch 15 has a first contact 1
5a and a bushing type switch provided with a second contact 15b,
When the suppressing member 15c is pushed lightly, the first contact 15a is turned on, and when it is pushed strongly, the first contact 15a and the second contact 15 are turned on.
Both of b are turned on. Each contact 15
The on/off signals of a and 15b are input to the CPU 21 as a switch operation signal.

Connected to the CPU 21 are a drive circuit 24 for a motor 23 that drives a feed mechanism that feeds receipt paper, and a drive circuit 26 for a motor 25 that drives a feed mechanism that feeds journal paper.

The CPU 21 performs the control shown in FIG. 3 in response to a switch operation signal from the receipt feed switch 14. That is, the ON signal is output from the first contact 14a, and the second contact 1
When an off signal is input from the drive circuit 4b, the drive circuit 24 is controlled to feed the receipt paper at a preset standard relatively slow speed.

Further, when an ON signal is input from both the first contact 14a and the second contact 14b, the drive circuit 24 is controlled to feed the receipt paper at a relatively fast speed twice the standard speed. I have to.

The drive circuit 24 is controlled to stop feeding the receipt paper when the receipt paper runs out or when the switch operation is stopped and both the first contact 14a and the second contact 14b are turned off.

Further, the CPU 21 performs the control shown in FIG. 4 in response to a switch operation signal from the journal feed switch 15. That is, the ON signal is output from the first contact 15a, and the second
When an off signal is input from the contact 15b, the drive circuit 26 is controlled to feed the journal paper at a preset standard relatively slow speed. Further, when an ON signal is input from both the first contact 15a and the second contact 15b, the drive circuit 26 is controlled to feed the journal paper at a relatively fast speed twice the standard speed. ing.

Then, when the feeding of the journal paper is finished or the switch operation is stopped, the first contact 15a and the second contact 15
The drive circuit 26 is controlled so as to stop when both of the drive circuits b are turned off.

In this embodiment having such a configuration, when the receipt paper becomes slack and the slack is to be corrected, the receipt feed switch 14 is lightly pressed. Thus, only the first contact 14a is turned on, the motor 23 is driven to rotate at a low speed by the drive circuit 24, and the receipt paper is fed at the standard slow speed.

Similarly, when the journal paper becomes slack, the journal feed switch 15 is lightly pressed. Thus, only the first contact 15a is turned on, the motor 25 is driven to rotate at a low speed by the drive circuit 26, and the journal paper is fed at the standard slow speed.

In this way, when correcting slack in receipt paper or journal paper, the paper is fed at a slow speed.

Further, when a new receipt paper is set and the paper is fed and cut to trim the leading edge, the receipt feed switch 14 is strongly pressed. Thus, both the first contact 14a and the second contact 14b are turned on, and the drive circuit 24 drives the motor 23 to rotate at high speed, and the receipt paper is fed at twice the standard speed.

In this way, when preparing the leading edge of a new receipt paper, the receipt paper is fed at a high speed, and the work of setting the receipt paper can be completed in a short time.

Further, when winding up the journal paper at the time of payment, for example, the journal feed switch 15 is strongly pressed. Thus, both the first contact 15a and the second contact 15b are turned on, and the drive circuit 26 drives the motor 25 to rotate at high speed, and the journal paper is fed at twice the standard speed.

In this way, when the journal paper is wound around the winding roller, it is fed at a high speed, and the winding work of the journal paper can be completed in a short time.

Next, another embodiment of the invention will be described with reference to the drawings.

Note that the same parts as in the above embodiment are given the same reference numerals, and detailed explanations will be omitted.

As shown in FIG. 5, see-saw type self-resetting switches 34 and 35 are provided as receipt feed switches and journal feed switches, and rotating members 34c and 3
By rotating 5c back and forth, the first contact 34a,
35a and the second contacts 34b, 35b are selectively turned on and off. For example, when the first contacts 34a, 35a are turned on, the paper sheet and the journal paper are fed at the standard speed, and the second contacts 34b, 35b are turned on. When this occurs, the receipt paper and journal paper are fed at twice the standard speed.

Therefore, in this embodiment as well, receipt paper and journal paper can be fed at a speed of 2PIt by operating the switches 34 and 35, and the same effects as in the previous embodiment can be obtained.

In the above embodiment, the speed of receipt paper and journal paper can be set to two types using a switch with two contacts, but the speed is not necessarily limited to this, and a switch with three or more contacts can be used. It may also be possible to set the speed to 3F1 or higher.

Further, although the above embodiment describes the application of the present invention to a receipt/journal printer for an electronic cash register, the present invention is not necessarily limited to this, and in short, it can be applied to any printer that uses long sheets of paper. It is something.

[Effects of the Invention] As detailed above, according to the present invention, a switch having multiple contacts is used, and the paper feed speed is changed depending on the on/off state of each contact, and the paper feed speed is adjusted according to the purpose. It is possible to provide a printer whose speed can be set.
