Embodiment Construction

[0032] Hereinafter, an embodiment in which the recording device of the present invention is embodied as an inkjet printer (hereinafter referred to as "printer") will be described with reference to the drawings. In addition, in the following description, when referring to "front-rear direction", "left-right direction", and "up-and-down direction", it means the direction based on the direction shown by the arrow in each drawing.

[0033] like figure 1 As shown, a printer 11 as a recording device includes a substantially rectangular parallelepiped main body 12, and an automatic paper feeder 13 as a conveying device is mounted on the back side of the main body 12, and the automatic paper feeder 13 is used to supply the paper p. The automatic paper feeder 13 has: a paper guide 17 as a loading section having a paper feed tray 14, a hopper 15, and an edge guide 16; and paper guides 17 to be loaded in a stacked state. The paper P is supplied one by one to a paper feeding drive mecha...

Abstract

The invention provides a feed device capable of preventing repeat delivery of lower sheet member of the uppermost sheet member, when the uppermost sheet member loaded in a stacked state is delivered,the invention also provides a recording device. The feed device including: a loading unit in which a plurality of sheet members is loaded in a stacked state; a delivery member which performs a feed operation in a state in which a contact surface thereof is in contact with an uppermost sheet member of the sheet members loaded on the loading unit and delivers the sheet member by rotating of the uppermost sheet member; a gate member has an inclined surface with which a front end of the sheet member delivered by the delivery member collides with; the gate member is moved in a direction of the delivery member leaving by the the uppermost sheet after collision of the front surface and the inclined surface, and thereby a space capable of being passed by the uppermost sheet is formed between thedelivery member and the gate member. In further, the feed device also includes a rotary member applying a pressing force to the sheet member underlying when the front end of the uppermost sheet passing through the space.

Description

technical field [0001] The present invention relates to, for example, a conveying device such as a paper feeding device, and a recording device such as an inkjet printer including the conveying device. Background technique [0002] Conventionally, in recording devices such as printers, in order to be able to continuously record on a plurality of sheets (sheet members), there is a recording device having a paper feeding device (transport device) that places sheets of paper in a stacked state. A plurality of sheets of paper are automatically conveyed to a position facing a recording head (recording mechanism) while being separated one by one (for example, Patent Document 1). [0003] The paper feeding device of this patent document 1 has: a paper cassette (loading unit) capable of loading a plurality of sheets in a stacked state; and a paper feeding roller (delivery member) on the uppermost paper and rotate to output the uppermost paper toward the conveying direction by utili...
