Problems solved by technology
[0006] However, in the above-mentioned conventional sheet conveying device, since the pressing force of the first roller on the sheet is adjusted by the rotation speed of the motor, the sheet can be reliably moved along the conveying direction regardless of the number of sheets loaded. sent out, complex control must be performed
In addition, it is difficult to set such an appropriate pressing force only by the self-weight of the cage and the first roller.

A sheet conveying device capable of reliably conveying sheets regardless of the number of loaded sheets and capable of stable sheet conveyance with a simple structure. The sheet conveying device (1) has: a sheet loading unit (80); a first roller (11); a second roller (12) rotating around a rotation axis (X12); ) swings, the first roller (11) is supported as a rotatable cage (30); the opposite wall portion (71) opposite to the sheet loading portion (80) across the cage (30); A pressing unit (50) for pressing the first roller (11) toward the sheet loading portion (80) side between the wall portion (71) and the holder (30). The pushing unit (50) has: a holding part (60), which is displaceably supported on the holding frame (30), and can abut against the opposite wall part (71); and a biasing spring (51), which is located on the holding Between the part (60) and the cage (30), the force is exerted separately so that the retaining part (60) and the opposite wall part are maintained regardless of the swing of the cage (30) around the rotation axis (X12). (71) The state of contact.
Description
technical field [0001] The present invention relates to a sheet conveying device. Background technique [0002] Patent Document 1 discloses an example of a conventional sheet conveying device. The sheet conveying device includes a sheet loading unit on which one or more sheets are loaded, and a first roller that sends out the sheet loaded on the sheet loading unit in a conveying direction. In addition, the sheet conveying device has a second roller located downstream of the first roller in the conveying direction, rotating around a rotation axis extending in the width direction of the conveyed sheet, and transporting the plurality of sheets. The sheets are separated one by one; and a cage supported so as to be swingable about a rotation axis supports the first roller so as to be rotatable. [0003] The cage is provided with a transmission portion that transmits the rotation of the second roller around the rotation axis to the first roller. The transmission unit includes: ...
