Embodiment

[0024] in figure 1 , figure 2 In the medium transport device 1 of the embodiment, the transport path 2 is provided, and the transport path 2 is formed by arranging the upper guide plate 3 and the lower guide plate 4 at intervals. On one side of the lower guide plate 4, a reference surface 5 serving as a reference for medium conveyance is formed. Conveyor Path 2 figure 2 The left side of the middle is the media insertion port 6. The insertion port 6 also doubles as a medium discharge port. Media of different sizes are conveyed in the conveying path 2, but the width of the conveying path 2 is formed to be wide so that all the media can be conveyed.

[0025] Feed rollers 7a and 7b are rotatably arranged on the conveying path 2. The feed rollers 7a and 7b are rollers that convey the medium in the direction of arrow A, and are rotationally driven by a motor described later. The pressing rollers 8a and 8b can be press-contacted to the feed rollers 7a and 7b, respectively. The fee...

Abstract

The invention provides a medium conveyer which can rapidly and accurately detect the length of a medium in a conveying direction so as to avoid the situation of inability to conveying the medium. After a medium (P) is absorbed into a convey channel (2), the inclined angle (alpha) of the medium (P) can be obtained by avertence detection sensors (18, 19), and the length in the convey direction (LB) can be calculated based on the detection signals of the avertence detection sensors (18 or 19) and the detection signals of a medium detection sensor (30). The length in the convey direction (LB) is compared with the distance (Lp) between feeding rollers (7a, 7b) and feeding rollers (11a, 11b), so as to determine whether the medium (P) can be absorbed in or not under the condition when the feeding rollers (7a, 7b) tightly clamp the medium (P), thereby preventing the situation that the medium (P) absorbed in can not be conveyed due to the length of the medium is shorter than the distance (Lp) between rollers.

Description

Technical field [0001] The present invention relates to a medium conveying device that conveys a plurality of media of different sizes, and more particularly, to a medium conveying device that detects whether the medium can be conveyed by detecting the oblique movement of the medium. Background technique [0002] Conventionally, as such a medium conveying device, there is, for example, a device disclosed in Patent Document 1 below. The device disclosed in Patent Document 1 is configured to include a feed roller that transports a medium on a medium transport path, an edge roller that pulls the medium aside, and two skew detection sensors arranged in a direction orthogonal to the transport direction , When the skew detection sensor detects the skew of the medium, it is a device that uses the side roller to close the side after the medium is transported to the appropriate position according to the skew angle. [0003] In order to confirm whether the medium can be conveyed in the medi...
