Abstract

(57) [Summary] [Purpose] In a handy scanner that can be attached to and detached from a main body with automatic paper feed, paper was conventionally conveyed by pressing a transparent member against a roller with a spring, so a mechanical relative misalignment occurred It was a cause of unevenness. An object of the present invention is to provide a configuration in which the mechanical relative position is constant and to eliminate unevenness in paper feed. [Configuration] U in which the transparent member 11 is installed on the transport roller 22
The mounting means 3A having the groove 3B is arranged, and the spring 12A is arranged between the transport roller 22 and the mounting means 3A.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to an image input device, and more particularly to a paper feeder such as a fax machine or a scanner printer. Regarding the improvement of the structure.

[0002]

[Prior art]

  An image input device such as a fax machine or a printer having a conventional scanner is shown in FIGS. As shown, the paper P passes between the handy scanner 1 and the main body 2. It The transparent member 11 is attached to the bottom of the handy scanner 1 via the spring 12. It is attached.   An opening is formed in a part of the bottom surface of the handy scanner 1, and the transparent member 11 The transparent member 11 also serves as the mounting means 3, and is arranged between the spring 12 and the mounting means 3. ing. Further, the transparent member 11 is supported by the spring 12 with respect to the carrying roller 22 on the main body side. It has been pressed against.   Next, the operation will be described. Now, when the paper P is inserted from the right side in the figure, the transparent member 1 1 moves up by the thickness of paper. However, there is some play before and after, so move to the left. In addition, in case of FAX etc., the motor stops and drives repeatedly in synchronization with the other party. others Due to the backlash of the gears, the transport roller 22 moves left and right. Yo The transparent member 11 moves to the left when driving, moves slightly to the right when stopped, and moves to the left when driving again. Move.

[0003]

[Problems to be solved by the device]

  In the above-mentioned conventional structure, the paper feed amount changes when driving at the initial stage and after the stop. Therefore, there is a drawback that uneven printing occurs.   Therefore, the present invention has been made to solve the above-mentioned conventional drawbacks, and is transparent. It is an object of the present invention to provide an image input device in which the member does not move back and forth and printing unevenness does not occur. To aim.

[0004]

[Means for Solving the Problems]

  Therefore, according to the present invention, in order to achieve the above-mentioned object, the transparent member is fixed to the attaching means. The U groove of the mounting means is arranged on the roller of the main body, and the spring is the roller and the mounting means. Characterized by being placed between and.

[0005]

[Action]

  In the above structure, the transparent member is positioned on the carrying roller of the main body through the mounting means. Therefore, it is not affected by stopping and driving the motor. Therefore, An image input device that solves the problem that the transparent member moves back and forth and does not cause uneven printing Can be provided.

[0006]

【Example】

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.   In the figure, the handy scanner 1 is detachable from the main body 2. On the body 2 The rollers 22 for conveyance are arranged in a rotatable state. On the other hand, the mounting means 3A The transparent member 11 is fixed. The mounting means 3A has a suitable shaft for the transport roller 22. There is a U-groove 3B that allows easy fitting, and the mounting means 3A is provided with a transport groove via the U-groove 3B. Is placed on the roller 22. The transparent member 11 is attached to the conveying roller 22 on the main body side via the attaching means 3 and the spring 12A. It is configured to be pressed against the transport roller 22 by.

[0007]   Next, the operation will be described. Now, when the paper P is inserted from the right side in FIG. The material 11 moves upward by the thickness of the paper. Further, the mounting means 3A is conveyed through the U groove 3B. Since it is arranged on the roller 22, it moves upward by the thickness of the paper like the transparent member 11. However, it does not move back and forth. By the way, FAX etc. Stops and drives repeatedly. Therefore, due to the effect of gear backlash, etc. The feed roller 22 moves left and right. However, the transparent member 11 is fixed to the mounting means 3A. It moves in the direction of rotation together with the transport roller 22 because of its presence, but when the motor is driven to the left, It does not move to the right when stopped.   Therefore, the problem that the transparent member 11 moves back and forth is solved, and printing unevenness does not occur. An image input device can be provided.

[0008]

[Effect of device]

  Since the present invention is configured as described above, it has the following effects. Provided is an image input device in which a transparent member does not move back and forth and printing unevenness does not occur. You can Also, since the handy scanner can be separated, the paper feed section can be It can be made into a personal computer and is not affected by the detached state of the handy scanner.
