(First Embodiment)
FIG. 1 is a schematic view of an image reader A according to the first embodiment of the present invention.

<Device configuration>
The image reading device A transports one or a plurality of transport media S loaded on the mounting table 1 one by one from the paper feed port to the discharge port along the path RT in the main body, reads the image, and reads the image in the discharge tray. It is a device to discharge to 2. The transport medium S for reading an image is, for example, a sheet of OA paper, a check, a check, a business card, a card, or the like, and may be a thick sheet or a thin sheet. Examples of cards include insurance cards, driver's licenses, credit cards and the like. The transport medium S also includes a booklet such as a passport. When targeting a booklet, the holder 200 can be used. By accommodating the booklet in the spread state in the transparent holder 200 and placing it on the mounting table 1, the booklet is conveyed together with the holder 200 and the image can be read.

<Paper>
A first transport unit 10 is provided as a feed mechanism for feeding the transport medium S along the route RT. In the case of the present embodiment, the first transport unit 10 includes a feed roller 11 and a separation roller 12 arranged to face the feed roller 11, and sequentially transfers the transport media S on the mounting table 1 in the transport direction D1. Transport. The driving force is transmitted to the feed roller 11 from the drive unit 3 such as a motor via the transmission unit 5, and is rotationally driven in the direction of the arrow in the figure (the positive direction in which the transfer medium S is conveyed along the path RT). The transmission unit 5 is, for example, an electromagnetic clutch, and the driving force from the driving unit 3 to the feed roller 11 is interrupted.

It should be noted that such a transmission unit 5 may not be provided when the feed roller 11 is driven in only one direction.

<Separation structure>
The separation roller 12 arranged to face the feed roller 11 is a roller for separating the transport media S one by one, and is in pressure contact with the feed roller 11 at a constant pressure. In order to secure this pressure contact state, the separation roller 12 is provided so as to be swingable and is configured to be urged to the feed roller 11. The separation roller 12 is rotationally driven in the direction of the solid arrow (the direction opposite to the forward direction of the feed roller 11) by transmitting the driving force from the drive unit 3 via the torque limiter 12a.

Since the torque limiter 12a regulates the transmission of the driving force of the separation roller 12, when it is in contact with the feed roller 11, it rotates in the direction (direction of the broken arrow arrow) that accompanies the feed roller 11. When a plurality of transport media S are transported to the pressure contact portion between the feed roller 11 and the separation roller 12, the two or more transport media S are separated so as not to be transported downstream.

In the present embodiment, the separation roller 12 and the feed roller 11 form a separation mechanism, but such a separation mechanism does not necessarily have to be provided, and the transport media S are sequentially fed to the path RT one by one. It may be a feeding mechanism. Further, when the separation mechanism is provided, instead of the configuration like the separation roller 12, a separation pad that applies a frictional force to the transport medium S is pressed against the feed roller 11 to have the same separation action.

In the present embodiment, since the NFC reader 113 is arranged on the feed tray 110, the position of the NFC reader 113 when the user places the transport medium S on the feed tray 110 before executing the user authentication. It is assumed that it will be difficult for the user to recognize the NFC reader 113, but by displaying an image or guidance indicating that the NFC reader 113 is provided in the center of the delivery tray 110, the user can determine the position of the NFC reader 113. It will be easier to understand.

As described using each embodiment, the NFC reader 113 in the image reader according to the present invention feeds in the thickness direction (normal direction of the mounting surface) of the transport medium S shown in FIG. 8 (b). It is characterized in that the tray 110 is arranged side by side with the interlocking mechanism 111b in the transport direction when the tray 110 is viewed. Further, the thickness of the feed tray 110 can be reduced by at least a part of the interlocking mechanism 111b located at the same position (height in the thickness direction) in the thickness direction.

Further, at least a part of the conversion board 118 for connecting (converting) the internal cable 117 drawn from the NFC reader 113 to the connection cable 116 is in the same position as the feed extension tray 112 that overlaps with the interlocking mechanism 111b in the thickness direction. By arranging them in such a manner and arranging them at positions overlapping with the interlocking mechanism 111b in the thickness direction, the conversion board 118 can be saved by utilizing the thickness of the feeding extension tray 112 and the feeding tray 110 in which the interlocking mechanism 111b is arranged. It can be arranged in a space, and the feed tray 110 can be miniaturized.

The embodiments described above are examples, and the present invention can make various modifications to them.
