Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0030] figure 1 It is a diagram showing the appearance of the printing device 10 according to the embodiment of the present invention.

[0031] The printing device 10 is a printer that prints on continuous paper S (recording medium, medium) such as label paper formed by attaching labels to elongated backing paper at constant intervals, and is also called a label printer. The printing device 10 is wired or wirelessly connected to an information processing terminal via a USB (Universal Serial Bus) cable or a LAN (Local Area Network) Print data to print.

[0032] exist figure 1 In each figure described later, the symbol FR represents the front of the printing device 10 , the symbol LH represents the left side of the printing device 10 , the symbol RH represents the right side of the printing device 10 , and the symbol UP represents the upper side of the printing device ...

Abstract

The present invention provides a conveying device and a printing device in which the opening and closing states of a plurality of suction holes are changed with a simple structure and the suction force is easily ensured. A venetian blind drum that rotates around a rotation axis extending in the width direction, and a suction fan that generates negative pressure in the internal space of the venetian blind drum are provided. And, set one of the suction holes adjacent in the width direction as the first suction hole, and set the other suction hole as the second suction hole, and make the suction chamber communicated with the first suction hole and The communication hole is set as the first communication channel, and the suction chamber and the communication hole communicated with the second suction hole are set as the second communication channel. In this case, the venetian blind drum functions as a venetian blind that selectively changes the opening and closing states of the first communication passage and the second communication passage in accordance with rotation.

Description

technical field [0001] The invention relates to a conveying device and a printing device. Background technique [0002] A printing device is known that includes: an inkjet head that ejects ink to a medium being conveyed; suction hole. [0003] As such a printing device, there is disclosed a structure, etc., which has an adjustment mechanism for adjusting the position in the tape width direction of the air hole group that generates negative pressure, and the adjustment mechanism is equipped with a plurality of branches connected to the air hole. closed on-off valve (for example, refer to Patent Document 1). [0004] In addition, the printing device also discloses a configuration in which the upper platen has a plurality of platen holes, and the lower platen has a plurality of holes that slide in the sub-scanning direction to change the size of the holes penetrating the upper and lower platens. Plate member (for example, refer to Patent Document 2). [0005] However, in th...
