Abstract

PURPOSE:To check the setting state of an original even if a platen cover is closed by forming a translucent original pressing part and illuminating the original by illumination lamps. CONSTITUTION:When the original 8 is set up on an original placing plate 3, the platen cover 1 is closed and then an illumination lamp 7 button on the operation buttons 9 mounted on a machine body 2 is depressed, the illumination lamps 7 arranged on the four corners of the lower part of the board 3 illuminates the original 8 from its back, the image of the original 8 is projected to the surface of a pressing part 4 of the cover 1 and whether the original 8 on the board 3 is set up on a precise position or not can be checked before starting the operation of the copying machine. The cover 1 is constituted by the original pressing part 4 formed by a translucent material and a frame body 5 holding the periphery of the pressing part 4, one end of the cover 1 is supported by a supporting axis 6 and the other end side can be opened/closed vertical around the supporting axis 6.

In conventional copying machines, when the platen cover is closed with a document placed on the document tray, the platen cover is made of an opaque material, so the document must be closed before the copying machine starts operating. It was not possible to check whether the original on the tray was placed in the correct position.

Therefore, when the platen cover is closed, the position of the document on the document tray may shift due to the pressure of the platen cover.
In such a case, the copying surface of the original is shifted, resulting in a disadvantage that copying errors are likely to occur.

Here, the semi-transparent material forming the original holding part (4) is illuminated by an illumination lamp (7) or an exposure lamp (not shown) that forms an electrostatic latent image on the photosensitive drum. Any material that exhibits a transmittance that does not dazzle the person operating the copying machine can be used. Specifically, plastic, glass, etc. that exhibit a transmittance of about 80 inches can be used. Note that depending on the illumination intensity of the illumination lamp (7), it is also possible to use a material with even lower transmittance. On the other hand, if a material with high transmittance is used, when the copying machine starts operating, the person operating the copying machine will be dazzled by the light from the exposure lamp leaking from the platen cover (11). An opaque cover (not shown) for further covering (1) may be provided so that one end can be opened and closed in the vertical direction.

In addition, although the illumination lamp (7) is mounted on the document tray (8) side in this embodiment, it is not limited to this position, and can be mounted on any part on the platen cover (1) side. For example, as shown in FIG.
Even if this is done, the original (8) can be similarly projected onto the original holding part (4). Further, the number of illumination lamps is not limited to four, as a matter of course, and may be arbitrary.

The present invention has the above-described configuration, and it is possible to check whether the original on the original table is set in the correct position with the platen cover closed before starting the operation of the copying machine. Therefore, even if the document shifts from its proper position due to pressure or wind pressure when the platen cover is closed, this can be easily detected, and this allows you to copy the document. It is possible to prevent ffi S copying, which occurs when the side is not accurately copied, and it is also possible to prevent wasteful consumption of copying paper, toner, etc. caused by conventional copy mistakes.
The practical effects of the present invention are significant.
