Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、記録紙の安定した搬送を行うのに好適なハ
ードコピー装置に関する。The present invention relates to a hard copy apparatus suitable for stable conveyance of recording paper.
従来の装置は、特公昭56−12586号に記載のように、
装置内部におかれた給紙ローラに記録紙を圧着し、給紙
ローラと記録紙の摩擦により記録紙の給紙，搬送を行う
機構となっていた。The conventional device, as described in Japanese Patent Publication No. 56-12586,
The mechanism is such that the recording paper is pressure-bonded to the paper feed roller inside the apparatus, and the recording paper is fed and conveyed by friction between the paper feed roller and the recording paper.
上記従来技術は、給紙ローラの埃などの付着による摩
擦係数の低下による搬送力の低下についての配慮がなさ
れておらず、また給紙ローラはハードコピー装置内部に
位置するため、給紙ローラの搬送力の低下には装置を分
解し保守をする必要が生じるという問題があった。The above-mentioned conventional technology does not take into consideration the reduction of the conveying force due to the reduction of the friction coefficient due to the adhesion of dust or the like on the paper feed roller, and the paper feed roller is located inside the hard copy device. There is a problem in that it is necessary to disassemble and maintain the device in order to reduce the carrying force.
本発明の目的は、ハードコピー装置内の給紙ローラの
保守を装置の分解なしに行うことにある。An object of the present invention is to perform maintenance of a paper feed roller in a hard copy device without disassembling the device.

る構成とする。The above objects are achieved by using a cleaning member that comes into contact with the paper feed roller by the paper feed operation and wipes the surface by rotation of the paper feed roller and does not enter the printing mechanism. More specifically, a paper feed table in which the recording paper is stored, a rotation transmission member for conveying the recording paper from the paper feed tray, the recording paper is nipped together with the rotation transmission member, and the recording paper is rotated. In a hard copy device having a pressing member that presses the transfer member so that the transfer member can be conveyed, the rotation transfer can be held at a position of the paper feed table where the recording paper is stored, and at this time, a portion facing the rotation transfer member. A cleaning member, in which a cleaning unit is arranged so as to be capable of pressure contact with the member, is configured to be detachably accommodated in the paper feed table from the outside of the apparatus. In addition, the cleaning unit of the cleaning member is configured such that pressure contact and separation with respect to the rotation transmission member are repeated a plurality of times.

される。In a normal paper feeding operation, the rotation transmission member is brought into close contact with the recording paper in the paper feed table and is rotated, whereby the recording paper is conveyed into the printing mechanism and printing is started. Further, in the cleaning operation, even when a cleaning member is provided in the paper feed tray instead of the recording paper, the rotation transmission member is brought into close contact with the paper by the paper feeding operation as in the case of the recording paper. The rotation transmitting member rotates and tries to convey the cleaning member, but the rotation transmitting member stops in the paper feed table because the structure does not enter the inside of the printing mechanism. The rotation transmitting member contacts the cleaning portion of the cleaning member and rotates to remove the attached dirt. Further, since the cleaning member having the cleaning unit can be taken in and taken out from the outside of the apparatus, the cleaning unit can be cleaned and the cleaning effect is improved.

にすることによりクリーニング動作を開始する。FIG. 2 is a diagram showing the cleaning operation of this embodiment. As shown in the figure, the base 1 is placed in the paper feed tray 9 instead of the recording paper. The paper feed roller 4 is a paper feed gear 8-
It is driven by the drive motor 5 via 1, 8-2. The drive motor 5 is a rotation amount detector 6 such as a rotary encoder.
Is installed. Paper detectors 7-1 and 7-2 such as photo couplers are provided in the path of the recording paper in the normal paper feeding operation. Further, the paper feed table 9 has a pressure plate 14, and the movement of the upper and lower arms 11 causes the recording paper to be pressure-bonded to the paper feed roller 4 in a normal paper feed operation.
As shown, the cleaning tip 2 is pressed. The upper and lower arms 11 are driven by a motor 15 via upper and lower gears 10-1 and 10-2. Rotary echo 6, paper detectors 7-1,7
The output of −2 is input to the control circuit 12. The operation switch 13 is connected to the control circuit 12, and the operation switch 13 is turned on.
Then, the cleaning operation is started.

でないことがあげられる。When the operation switch 13 is turned on, the control circuit 12 drives the motor 15 to move the upper and lower arms 11 to repeat the pressure contact and separation of the cleaning chip 2 to the paper feed roller 4 a plurality of times to press the cleaning chip 2.
At the same time, as shown in the figure, the recording sheet is not actually present on the base 1, but the sheet detector 7-1 sends a signal indicating that the sheet is present to the control circuit 12 by the reflection sheet 3 having the same reflectance as the recording sheet. Then, the control circuit 12 turns on the paper feed motor 5. The cleaning chip 2 attached on the base 1 is the paper feed roller 4
However, the base 1 is stopped by the paper feed table 9 by the paper feed table 9, and the cleaning chip 2 is also stopped.
Since the paper feed roller 4 continues to rotate, it is rubbed against the cleaning chip 2 to remove dirt on the surface. Control circuit
Reference numeral 12 counts the rotation amount after the paper feed motor 5 is turned on by the signal of the rotation amount detector 6, and if the paper detector 7-2 does not detect the paper within a certain rotation amount, it is judged to be abnormal and is fed. Stop paper operation. In this case as well, the reflection sheet 3 is not conveyed to the paper detector 7-2, so the operation is stopped after a certain rotation. By the abnormal operation, the dirt on the surface of the paper feed roller 4 is removed, and it is possible to prevent the paper feed operation failure due to the decrease in the coefficient of the coefficient due to the dirt. Further, as an effect peculiar to this embodiment, there is no need to modify the control circuit and the hard copy device.

り良好なクリーニング効果が可能となる。According to the present invention, in the cleaning operation, since the cleaning portion of the cleaning member is brought into pressure contact with and separated from the rotation transfer member for transporting the recording paper in the apparatus, it is possible to remove dirt and the like on the rotation transfer member. Can be stably supplied. Further, since the cleaning member can be held at the position where the recording paper of the paper feed tray is stored,
When the normal copying operation is performed, the cleaning unit of the cleaning member automatically repeats the pressure contact and separation with respect to the rotation transmitting member a plurality of times, so that the rotation transmitting member can be easily and reliably cleaned. Further, since the cleaning member having the cleaning portion can be taken in and taken out from the outside of the apparatus, the cleaning portion can be cleaned and a better cleaning effect can be achieved.
