Abstract

PURPOSE:To enable manual paper supply to be automatically detected without requiring a troublesome switching operation and properly operate a recording paper supplying device, by discriminating whether a recording paper is supplied to a main body of a recorder and controlling the driving of the recording paper supplying device according to the result of discrimination. CONSTITUTION:A controlling part 4 has the function of discriminating whether a recording paper is supplied to a main body 1 of a recorder when a recording paper supplying device 8 is stopped. By this, it is automatically discriminated whether the recording paper is manually supplied at present. When supply of the recording paper is not performed, the supplying device 8 is driven to supply a recording paper, then recording of lines of data stored is performed, and it is judged whether recording of the next line can be performed, that is, whether a recordable space is left. By such a controlling operation, it can be automatically detected whether manual paper supply has been performed, and a paper-supplying operation by the supplying device 8 can be properly effected.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a recording device that uses a recording paper feeding device to perform manual paper feeding and automatic paper feeding. It is something.

[Conventional technology]

Conventionally, in this type of device, before operating the main body of the recording device, a switch provided on the feeding device is changed depending on the paper feeding method, that is, manual paper feeding or automatic paper feeding. It was designed to prevent duplicate paper feeding.

(Problem to be Solved by the Invention) However, it is extremely troublesome to switch the paper feeding method each time, and this is due to the use of a recording paper feeding device that attempts to simplify the paper feeding operation. There are problems in that it goes against the intention and is likely to lead to erroneous operation.

This invention has been made by focusing on the above-mentioned problems, and it is possible to automatically detect manual paper feeding without having to perform troublesome switching operations, and to operate the paper feeding device appropriately. The purpose is to provide equipment.

Means for Solving Problem C) This invention provides a determining means for determining whether or not recording paper is being supplied to the recording apparatus main body when the recording paper supply apparatus is stopped;
The apparatus further includes a control means for controlling the driving of the recording paper supply device in accordance with the determination result.

[Effect]

In this invention, when the recording paper supply device is stopped, it is determined whether or not recording paper is being supplied to the recording apparatus main body. As a result, it is automatically determined whether or not recording paper is currently being fed manually, and if the recording paper is not being supplied, the recording paper supply device is driven to feed paper. If the recording paper is being fed manually, the driving of the feeding device is stopped.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of this embodiment.
1 is the main body of the recording device; 2 is an operation/display unit that performs various manual operations such as selecting a recording mode and displays a predetermined display according to the human input; and 3 is a recording unit such as a recording head that performs recording operations on recording paper. , 4 is a control section as a control means for controlling each of the above-mentioned sections, and is composed of a well-known microcomputer or the like.

Reference numeral 5 denotes a recording paper detector for detecting recording paper placed in the recording apparatus main body 1, and its output is manually inputted to the control section 4. 6 is an interface unit that receives recording data from the host computer, and 7 is a driver that operates the recording paper supply device, which will be described later, in response to a signal from the control unit 4.
6 are built into the main body 1 of the recording apparatus. Reference numeral 8 denotes a recording paper supply device, which supplies recording paper to the recording apparatus main body 1 by a motor 9 driven in accordance with the output from the driver 7.

FIG. 2 is a flowchart showing the control operation in the above configuration.

When the power is turned on, information from the recording paper detector 5 is transmitted to the control unit 4.
This information is determined manually in step S1.

Here, if it is determined that there is no recording paper, the process moves to step S3, and if it is determined that there is recording paper, the recording paper currently present in the recording apparatus main body 1 is ejected in step S2, and then the process proceeds to step S3. 0N between device main body 1 and host computer
-Perform LINE processing. Next, in step S4, it is determined whether the recording apparatus main body 1 and the host computer are in the 0N-LINE state or 0FF- by manual input from the operation display section 2.
It is determined whether it is in the LINE state, and if it is determined that it is in the 0FF-LINE state, the process moves to step S5 and the 0FF
-LINE processing is performed, and if it is determined that the state is 0N-LINE, the process moves to step S6. In step S6, based on the information from the recording paper detector 5, it is determined whether recording paper is being supplied to the main body 1 of the apparatus, and if it is determined that recording paper is being supplied, the manual flag is set to "1". If it is determined that it is not being supplied (step S7), the manual flag is set to "0" and the process moves to the next step S9. Above step S4. The determination in S6 is performed by the control section 4. That is, the control section 4 has a function as a determining means for determining whether or not recording paper is being supplied to the apparatus main body 1 when the supply device 8 is stopped. In step SIO, it is determined whether or not recorded data has been received from the host computer. If it has not been received, the process returns to step S4 and the above operation is repeated, and when it is received, step SIO is executed.卆、、Go(In

After that, the process moves to step 318. In step 318, the current recording paper is ejected and step S
Return to step 4 and prepare to record the next page. Through the following control operations, it is automatically detected whether manual paper feeding has been performed,
The recording operation can be performed by properly performing the paper feeding operation by the feeding device 8.

Next, a second embodiment of the invention will be described.

This embodiment includes steps 316 to 316 in the first embodiment.
318, the control operations of steps 319 to S24 shown in FIG. 3 are executed. Below, the third
This will be explained based on the diagram.

As described above, if it is determined in step S16 that recording is not possible, it is determined whether the manual flag is "1" or "0", and "
If it is "0", the process moves to step 318, and if it is "1", the process moves to step S20. In step S20, the manual flag is cleared and the process moves to step S21. In step S21, 0FF-LINE processing is performed to notify the user of the end of manual paper feeding. Next, in step S22, the system waits until the 0N-LINE key is pressed, and presses the 0N-LINE key.
When it becomes NE, the process moves to step S23, and if it is determined that there is no recording paper based on the information from the recording paper detector 5, the process moves to step 318, and if it is determined that there is recording paper, the process moves to step S24. After setting the manual flag to "1", the process moves to step 31B.

As is clear from the above operation, the state is automatically set to 0FF-LINE after manual paper feeding, which is effective when manually feeding a large number of sheets.

〔effect〕

As explained above, according to the present invention, manual paper feeding can be automatically detected and the recording paper feeding device can be operated properly without having to perform the troublesome switching operations as in the past. Therefore, there is an effect that operability can be significantly improved.
