Problems solved by technology

[0007] However, in Patent Document 1, a plurality of pressing members are provided along the scanning direction, so when the media sensor and the pressing members overlap in the transport direction, there is a possibility that the end of the sheet cannot be accurately detected.
On the other hand, if the pressing member is arranged on the upstream side of the conveying path than the media sensor, the sheet cannot be pressed near the nozzle.
As a result, the sheet tends to warp, causing contamination, paper jams, etc.

Embodiment Construction

[0037] Embodiments of the present invention will be described below. In addition, embodiment described below is just an example of this invention, It goes without saying that the embodiment of this invention can be changed suitably within the range which does not change the summary of this invention. In addition, in the following description, the multifunction peripheral 10 is set to a usable state ( figure 1 state) defines the up and down direction 7 as the datum. Furthermore, the front-rear direction 8 is defined with the side of the multifunction peripheral 10 on which the opening 13 is provided as the near side (front). Furthermore, the left-right direction 9 is defined by viewing the multifunction peripheral 10 from the near side (front).

Abstract

The invention provides an ink-jet recording device capable of inhibiting the warp of the sheet material near the nozzle without affecting the detection on the end part of the sheet material along the width direction. A recording head (39) is disposed on a sliding rack (23), and is used to spray the ink droplets on a piece of recording paper (12). A medium sensor (110) is disposed on the upstream side of the sliding rack (23) closer to the transmission direction than the nozzle (40), and is used to detect the recording paper (12) on an embossing plate (42). A first abutting part (80A) is disposed on the upstream side closer to the transmission direction (16) than the nozzle (40). The downstream side of the transmission direction of the first abutting part (80A) is disposed on the recording paper (12) of a paper carrying plate (20), and the two ends of the scanning direction of the smallest sheet material of the shortest length of the scanning direction are close to the corresponding area of the inner side, and can be extended to the position overlapped with the detection area of the medium sensor (110) along the transmission direction (16).

Description

technical field [0001] The present invention relates to an inkjet recording apparatus that detects both ends in the width direction of a sheet conveyed along a conveyance path. Background technique [0002] Conventionally, an inkjet recording apparatus is known that includes a media sensor that detects an edge in the width direction of a sheet conveyed along a conveyance path to the vicinity of a nozzle of an inkjet head. The media sensor scans the conveyance path in a scanning direction by being mounted on a carriage, for example, to detect an end in the width direction of a sheet on the conveyance path. [0003] Also, inkjet recording apparatuses capable of recording images on sheets of various sizes and paper thicknesses are known. For example, since envelopes and the like are thicker than plain paper, they may warp from the conveyance path during conveyance. In this case, there is a possibility that the envelope may be contaminated by being scratched against the nozzle...
