Abstract

PURPOSE:To confirm the moving position of a photosensor from the outside even during the reading of an original and to read the image information of the original correctively by providing a sensor position display means for displaying the moving position of the photosensor. CONSTITUTION:The original 1 is set at a prescribed position on an original platen 2 and pressed by an original pressure cover 4. When the read start switch, etc., of a console panel 5 are operated in this state, the photosensor 3 moves from the position corresponding to the start terminal of the original platen 2 to the position corresponding to the end terminal to read the image information of the original 1. When the photosensor 3 moves as mentioned above, display devices a1-an of a sensor position display board 10 light in order corresponding to the moving position of the photosensor 3. Consequently, an operator can confirm the moving position of the photosensor 3 during the reading of the original 1, and the image information of the original can be read correctly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image reading device such as a copying machine for copying a document.

[Conventional technology]

FIG. 2 is a schematic diagram of an image reading apparatus according to a conventional image reading apparatus and an embodiment of the present invention. In the figure, 1 is the document to be read, 2 is the document table on which the document 1 is set, and 3 is the document 1
an optical sensor that converts the image information of the original 1 into an electrical signal by moving with respect to the surface of the original 1, a document holding cover 4 that holds down the original 1 and prevents light from the optical sensor 3 from being exposed to the outside; Reference numeral 5 denotes an operation panel on which a lamp indicating the power-on state of the apparatus and a switch for instructing the start of reading the document 1 are attached.

Next, the operation will be explained. A document 1 is set at a predetermined position on a document table 2 and is held down by a document holding cover 4. In this state, when the reading start switch on the operation panel 5 is operated, the optical sensor 3 sequentially moves from a position corresponding to the starting edge of the original platen 2 to a position corresponding to the ending edge, and reads the image information of the original 1.

[The interlayer point that the invention attempts to solve]

Since the conventional image reading device is configured as described above, the document table 2 is covered by the document holding cover 4 while the document 1 is being read, and the operator cannot confirm the moving position of the optical sensor 3 from the outside. . Therefore, the document holding cover 4 may be opened in order to check the moving position of the optical sensor 3 during reading, which may expose the light from the optical sensor 3 to the outside, causing discomfort to the operator. However, there have been problems such as the document 1 slipping from a predetermined position and image information not being able to be read correctly.

This invention was made to solve the above-mentioned problems, and it is possible to check the movement position of the optical sensor from the outside without opening the document holding cover even while the document is being read. An object of the present invention is to provide an image reading device that can correctly read images.

[Means for solving problems]

The image reading device according to the present invention has a sensor position display means (sensor position display board 10) that displays the moving position of the optical sensor 3.
).

[Effect]

Sensor position display means (
The sensor position display panel 10) displays the moving position of the optical sensor 3 while reading the image of the original 1, and notifies the operator of the movement position.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

The general configuration of the image reading device according to an embodiment of the present invention has been described in FIG. 2, and therefore will not be described here. FIG. 1 is a configuration diagram of a sensor position display panel as a sensor position display means which is a feature of the present invention. In FIG. 1, a plurality of indicators alxan are arranged on the sensor position display panel 10, the indicator a1 lights up when the optical sensor 3 is at the position corresponding to the starting edge of the document table 2, and the indicator an lights up Lights up when the sensor 3 is at the position corresponding to the end of the document table 2, and the indicators a2 to a
The reference numeral n-1 lights up corresponding to the position where the optical sensor 3 is moving between the starting end and the ending end of the document table 2. Sensor position display panel 1 having such indicators a1 to an
0 is provided on the operation panel 5 in FIG. 2, for example.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2. A document 1 is set at a predetermined position on a document table 2 and is held down by a document holding cover 4. In this state, when the reading start switch on the operation panel 5 is operated, the optical sensor 3 sequentially moves from a position corresponding to the starting edge of the original platen 2 to a position corresponding to the ending edge, and reads the image information of the original 1. While the optical sensor 3 is moving in this manner, the indicators a1 to an on the position display panel 10 are lit up in sequence in accordance with the position of the optical sensor 3. Thereby, the operator can check the moving position of the optical sensor 3 while reading the original 1, and there is no need to open the original holding cover 4 and see the moving position of the optical sensor 3 during reading. Note that the sensor position display panel 10 in FIG. 1 shows a state in which the indicator a3 is lit, and the optical sensor 3
This indicates that the position has moved slightly toward the terminal end from the starting end.

〔Effect of the invention〕

As described above, according to the present invention, since the sensor position display means for displaying the moving position of the optical sensor is provided, the moving position of the optical sensor can be confirmed from the outside even while reading a document. There is no need to open the document holding cover during reading to see the moving position of the optical sensor, and the image information of the document can be read correctly.
