Embodiment approach

[0096] In the above-mentioned embodiment, the paper pressing device provided in the colorimetric device 20 is described as an example in which the paper S is pressed by the plate-shaped paper pressing member 22 , but the present invention is not limited thereto.

[0097] Figure 11 It is a figure which shows the schematic structure of the paper pressing apparatus of another embodiment. In this embodiment, the paper pressing device is provided on a paper feeding device such as a printer.

[0098] The paper feeding device includes a paper feeding tray 21', a paper feeding roller 22', a pressing mechanism 23', and a controller not shown. The paper feed tray is a member that stores stacked paper. The paper feed roller 22' is a member that presses the paper toward the paper feed tray 21'. The paper feed roller 22' comes into contact with the uppermost paper stored in the paper feed tray 21'. The pressing mechanism 23' is a mechanism that moves the paper feed roller 22' between ...

Abstract

To provide a medium-pressing device whereby it is possible to detect a malfunction of a power supply that outputs power for the purpose of pressing a medium. The invention is a medium-pressing device characterized by including a pressing member that presses a medium; a power supply that outputs power for the pressing member to press the medium; a detection section that detects displacement of an output section of the power supply; and a controller adapted to reduce the power output by the power supply from a state in which the pressing member presses the medium, and to detect malfunction of the power supply on the basis of detection results obtained from the detection section.

Description

technical field [0001] The invention relates to a medium pressing device for pressing a medium and an abnormality detection method. Background technique [0002] As a medium pressing device that presses a medium, for example, a mechanism for pressing a medium included in a paper feeding device is known, in which a plate-shaped bottom plate on which paper as a medium is placed is placed opposite to the bottom plate by operating a pressure lever. Roller crimping mechanism, the pressing rod is in contact with the outer plate to form a push-up member that can move up and down freely. (For example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 9-30663 [0004] However, there is a problem that it cannot be confirmed whether the above-mentioned mechanism for pressing the medium is reliably crimped, specifically, whether it is pressed with an appropriate pressure. Contents of the invention [0005] The present invention is ma...
