BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus having a paper feeding device capable of feeding paper of various sizes, and more particularly to a paper size detection means of the apparatus.

0002

[Prior Art] Conventionally, paper feeding devices capable of feeding paper of various sizes, so-called multi-purpose trays (hereinafter referred to as MP trays), have been used, especially in small-sized recording devices, to freely select the size of paper to be fed. It has been widely used because of its ability to perform

0003

[Problems to be Solved by the Invention] However, in the conventional example described above, although the paper size in the direction perpendicular to the transport direction can be detected in the MP tray, the paper size in the transport direction cannot be recognized before the printing operation. It was difficult.

[0004] Recognizing the paper size is essential for printing at accurate positions, especially in page printers such as laser printers that receive print data from a host computer and print.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a recording device that can perform accurate recording without data loss by detecting the paper size before the recording operation. It is about providing.

[0006]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a paper feeding device capable of feeding paper of various sizes, and recording on the paper fed by the paper feeding device. In the recording apparatus, the paper feeding device includes a paper holding part that is movable in a direction perpendicular to the paper feeding direction, and a first detection means for detecting the amount of movement of the paper holding part. The discharge paper stacking section of the recording apparatus main body has a paper stopper that is movable in the paper feeding direction, and a second detection means that detects the amount of movement of the paper stopper, and the recording apparatus main body The apparatus is characterized by comprising a control means for controlling recording on paper based on the detection results of the first detection means and the second detection means.

[0007]

[Operation] In the present invention having the above structure, the paper size in the direction perpendicular to the conveying direction is determined by the amount of movement of the paper presser of the paper feeding device.
The paper size in the transport direction is known by the second detection means detecting the amount of movement of the paper stopper of the discharged paper stacking section.

[0008] Then, the control means controls recording on the paper based on the detection results of the first detection means and the second detection means.

Embodiment FIGS. 1 and 2 show a first embodiment of the present invention.

FIG. 1 shows a multi-purpose tray (hereinafter M
1 is a schematic diagram of a page printer as a recording device having a P tray (denoted as P tray). Reference numeral 1 denotes a main body of a page printer as a main body of a recording device, which incorporates an engine controller, an image controller, an image forming process section, and an external interface section (not shown). 2 is an MP tray as a paper feeding device, and 3 is a paper presser as a paper presser, which slides in the direction of the arrow according to the paper size. Reference numeral 4 denotes a discharge paper stacking section, which also serves as the exterior of the page printer in this configuration. Reference numeral 5 denotes a paper stopper provided in the discharged paper stacking section, which can be moved according to the paper size.

FIG. 2 shows the connections between the paper size detection section, each controller of the printer, and the host computer.

Note that the same members as in FIG. 1 are designated by the same reference numerals and their explanations will be omitted. 5a is a first detection sensor as a first detection means for detecting the amount of movement of the paper stopper 5, and 3a is a second detection sensor as a second detection means for detecting the amount of movement of the paper presser 3. 6 is the engine controller and the first
, the image forming process and the paper conveyance are controlled based on the detection results of the second detection sensors 5a and 3a. 7 is an image controller which develops the image data sent from the host computer 8 into dot data and performs various image processing;
It also includes an interface section for exchanging information with. Here, the engine controller 6, image controller 7, and host computer 8 constitute a control means 20.

The paper presser 3 is slid in the direction of the arrow according to the paper size in the direction perpendicular to the transport direction. The size information at that time is sent to the engine controller 6. Also, slide the paper stopper on the discharged paper stacking section 4 in the direction of the arrow to match the size of the paper stacked on the MP tray 2. This paper size information in the transport direction is also sent to the engine controller 6.

The engine controller 6 determines appropriate paper size information from the above two size information and sends it to the image controller 7. The image controller 7 processes the image data based on the sent paper size information and sends the paper size information to the host computer 8.
send to

With the configuration and operation listed above, the host computer 8 can always accurately determine the size of the paper loaded in the recording device, and eliminates loss of image data due to paper size mismatch. etc. can be prevented from occurring.

A second embodiment of the present invention is shown in FIGS. 3 and 4.

Components that are the same as those in FIGS. 1 and 2 are designated by the same reference numerals, and their explanations will be omitted.

Reference numeral 9 in FIG. 3 is a paper stopper, which is functionally the same as the paper stopper 5 in FIG. There is. 10 is a paper loading cassette. In this recording apparatus, there are two systems of paper feeding means: the MP tray 2 and the paper loading cassette 10.
Paper is conveyed in the directions of arrows L1 and L2. When feeding paper using the MP tray 2, the paper size in the transport direction and vertical direction is recognized as in the first embodiment, and the paper size is sent to the host computer 8 via the engine controller 6 and image controller 7. will be sent. When feeding paper using the paper cassette 10, the paper size signal of the paper cassette 10 is given priority over the paper size signal of the MP tray 2 and the paper size signal of the discharged paper stacking section 4. Since there are two types of paper feeding devices, the host computer 8 or image controller 7 can specify the paper feeding section, and in that case, the paper size signal corresponding to the specified paper feeding section is given priority. .

[0019]

As explained above, when feeding paper to a recording device using a paper feeder, the paper size in the direction perpendicular to the conveying direction is determined by the first step that detects the amount of movement of the paper presser of the paper feeder. 1
The paper size in the transport direction is detected by a second detection means that detects the amount of movement of the paper stopper in the discharged paper stacking section, so that the paper size can be recognized by simply moving the paper presser and the paper stopper. becomes possible.

[0020] This allows the control means to recognize the paper size before the recording operation, making it possible to prevent data loss or the like due to paper size incompatibility.
