CONSTITUTION:The motor 19 for driving an automatic paper feed apparatus 17 driven by a driver 16 in a controllable manner in order to operate a paper feed roller in a predetermined mode is provided to the automatic paper feed apparatus 17 and the recording control program of an automatic paper feed mode for controlling and driving a recording head 12, a line feed motor 13 and a carriage motor 14 on the basis of the margin and number of figures set for the automatic paper feed apparatus 17 is stored in CPU2 and ROM16. When the automatic paper feed apparatus 17 is electrically connected to a recording apparatus 1 by connectors 18, 20, the connection of the connectors is detected and, on the basis of the detection signal SC, the printing range of the recording apparatus is automatically changed over to the margin and number of figures set for the automatic paper feed apparatus 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to the structure of a recording apparatus of a type in which an automatic paper feeder is removably attached.

(Prior Art) As recording devices such as printers and facsimile machines, serial type recording devices are widely used, in which a print head is mounted on a carriage that moves inward along the paper, and records are made by scanning the carriage. The print head usually has a plurality of fli! (for example, 321[
1i1) dot forming elements are arranged, and these dot forming elements are driven based on print pattern signals in synchronization with carriage feeding.

As the dot forming element, for example, a heating resistor is used in a multi-head head, an ink ejection opening (orifice) is used in an inkjet head, and a wire is used in a wired soot head.

In such recording devices, in addition to manually setting and recording paper, a removable automatic paper feeder (cut sheet feeder) is used to automatically feed and set paper one sheet at a time. ing.

When installing an automatic paper feeder in recording device 1, if the paper size that can be used for both devices is the same (for example, the printable range of the recording device is 80 digits (A4 size portrait), and the automatic paper feeder is attached to A4 size portrait There is no problem if the paper size that can be used for both is different (
For example, if the printable range of the recording device is 110 digits (A4 size horizontally), and the automatic paper feeder is capable of feeding A4 size vertical paper, the print may end up outside the paper if used as is. There is.

For this reason, with conventional recording devices, when using an automatic paper feeder, the margins and number of digits must be set one by one, which is a complicated operation. There was a problem with it coming out.

〔the purpose〕

The purpose of the present invention is to solve the problems of the prior art,
To provide a recording device in which a printing range is automatically set when automatic paper feeding is performed, and the possibility of printing out of the paper range can be eliminated.

〔overview〕

The present invention detects the connection of the connector when an automatic paper feeder is electrically connected to a recording device by a connector, and based on the detection signal, the printing range of the recording device is set to a margin and number of digits set for the automatic paper feeder. By automatically switching to
This aims to achieve the above objectives.

〔Example〕

FIG. 1 is a block diagram showing the configuration of a recording apparatus according to an embodiment of the present invention.

In FIG. 1, the control circuit (CPU) of the recording apparatus main body l
2 connects to the host computer 4 via interface 3.
is connected to and data signals are sent. The control circuit 2 is provided with a RAM 5 and a ROM 6, the data signal is temporarily stored in the RAM, and a recording operation is performed according to a program stored in the ROM 6. These control circuit 2, RAM 5, and ROM 6 are connected by an address/data bus 7, and data is written and read.

During the recording operation, the data signal of RAM5 and the RO
The M6 command signal is sent to the recording head driver 9, line feed morph driver 10, and carriage motor driver 11 via the I10 port 8, and these drivers (drive circuits) 9°10.11 drive the recording head 1.
2. Line feed motor 13 and carriage motor 1
4 is driven at a predetermined timing to perform recording.

Note that the recording apparatus main body 1 has triggers for various controls other than the recording operation, such as heating time control according to the ambient temperature, control of ink recovery operation at the home position, and control based on detection of the remaining amount of ink ribbon and ink. Various sensors 15 for obtaining signals are provided, and detection signals from these sensors are sent to the CPU 2 via the I10 port 8 and the address/data bus 7, and predetermined control operations are performed based on these signals.

In addition, the CPU 2 and the RO
A driver (drive circuit) 16 for the automatic sheet feeder (cut sheet feeder) drive motor controlled by M6 and a connector 18 for electrical connection to the automatic sheet feeder 17
is provided.

On the other hand, the automatic paper feeder 17, which is removably attached to the recording apparatus main body l, is configured to operate a paper feed roller (not shown) and, in some cases, a paper ejection roller (not shown), etc. in a predetermined mode. An automatic sheet feeder drive motor 19 is provided which is controlled and driven by the driver 16, and this drive motor 19 becomes capable of being controlled and driven by connecting a connector 20 to the connector 18 of the recording apparatus main body. .

The CPU 2 and the ROM 6 contain, in addition to a recording control program dedicated to the recording apparatus, a program for controlling and driving the recording head 12, line feed motor 13, and carriage motor 14 with the margin and number of digits set for the automatic paper feeder 17. A recording control program for automatic paper feeding mode is stored.

On the other hand, the connector 18.20 is also provided with electrodes 21.22 for detecting the electrical connection of the connector. These electrodes 21.22 form a kind of switch, and are turned on when the connector 18.20 is connected, and the connector signal SC representing this state is sent to the signal line 2.
3 to the CPU.

When the connector signal SC is sent to the CPU, the control mode of the recording apparatus main body 1 is automatically switched from the standard (dedicated) mode to the automatic paper feeding mode.

That is, the automatic paper feeder 17 is connected to the recording device 1.
8 and 20, the connection of the connector is detected, and the printing range of the recording device is automatically switched to the margin and number of digits set for the automatic paper feeder 17 based on the detection signal SC. It is configured.

For example, the printing range in the standard mode of the recording device 1 is 1
In the case of 10 digits, if the automatic paper feeder 17 is connected, the left margin will be 16 digits (based on the recording device) and the print range will be 80 digits (therefore, the right margin will be 16 digits based on the recording device). Automatically switches to a certain automatic paper feed mode.

According to the configuration described above, when the automatic paper feeder 17 is installed, the printing range is automatically switched to the margin and number of digits set exclusively for automatic paper feeding, so the printing range during automatic paper feeding can be easily and easily adjusted. It was possible to set the settings reliably, and it was possible to reliably prevent the printing range from going outside the range of the paper (cant sheet).

〔effect〕

As is clear from the above description, the present invention provides a recording device that can reliably prevent the printing range from extending outside the paper when an automatic paper feeder is used.
