Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrostatic recording device with optical forms overlay functionality.

In general, optical forms overlay in electrostatic recording devices is performed when the recording medium is a photoreceptor.
forming overlay information on a light-transmissive film;
A method is used in which the film is exposed by covering the main information on the photoreceptor with backlighting, but when there are many types of overlay information and they are interchangeable, currently which overlay information (form) is placed at the recording position. It is necessary for the operator to be able to determine whether the

For this reason, conventional methods have been used to display the types of overlay information using symbols, etc. However, as the types of overlay information increase, a problem arises in that symbols are easy to confuse.

This invention was made to solve the above problems, and it facilitates the management of many types of overlay information by displaying the contents of overlay information set at a recording position in a reduced size on the operation panel. ,
The purpose is to prevent operational errors by operators.

In order to achieve the above object, the present invention provides an electrostatic recording device having an optical forms overlay function, in which a plurality of types of overlay information are continuously formed along the longitudinal direction, and each overlay information is formed on the side thereof. An overlay film is formed by shifting the position of the reduced version in the longitudinal direction with respect to the corresponding overlay information, and this overlay film is moved along the longitudinal direction so that the required overlay information faces the photoreceptor. means for moving the overlay information to the recording position; a light source for illumination for exposing the photoreceptor to the overlay information moved to the recording position by the means; and reduction of the overlay information moved to the recording position on the overlay film. It is equipped with a projection device that projects the contents of the plate onto a projection window provided in the operation section.

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

FIG. 1 is a simplified external perspective view of an electrostatic recording device showing an embodiment of the present invention, in which a reduced version of overlay information is projected onto a part of the operation section, which is the upper surface of a housing 1. It has 2 windows. A back-illuminated screen is attached to this projection window 2.

FIG. 2 is a schematic diagram of the configuration of the recording device housed inside the casing 1 of FIG. 1.

In this example, an endless belt-shaped photoreceptor 4 is used as the photoreceptor. As shown in the figure, this belt-shaped photoreceptor 4 is guided by four rollers 3 and moved in the direction of arrow B, and a main information recording section 5, a developing device 6, and a transfer device are arranged around the belt-shaped photoreceptor 4. 7,
The recording material sequentially passes through a cleaning device 8 and the like, and is subjected to recording steps such as exposure, development, and transfer.

In this recording process, the main information is first exposed onto the belt-shaped photoreceptor 4 in the main information recording section 5 to form a latent image. Next, overlay information on an overlay film 9, which will be described later, is exposed onto the photoconductor 4 by the illumination light source 10, and a latent image of the overlay information is formed on the photoconductor 4, superimposing the latent image of the main information. Ru.

It goes without saying that the exposure of the main information in the main information recording section 5 and the exposure of overlay information by the illumination light source 10 are performed in synchronization with the rotation of the photoreceptor 4.

When the latent image on the photoreceptor 4 passes through a developing device 6, it is made visible by being coated with toner, for example, and then transferred to a recording medium such as a transfer paper (not shown) in a transfer device 7.

Thereafter, the surface of the photoreceptor 4 is cleaned by a cleaning device 8 and the photoreceptor 4 is reused.

As shown in FIG. 3, the overlay film 9 includes a plurality of types of overlay information 11a, 11b, . . .
... are continuously formed along the longitudinal direction, and overlay information 11a, 11b, ... is formed for recording the overlay information 11a, 11b, ...
The reduced versions 12a, 12b,
... are formed at the same time.

Note that overlay information 11a, 11 for recording
The formation positions of b, ... and the corresponding reduced versions 1
The formation positions of 2a, 12b, . . . are shifted in the longitudinal direction of the film 9 so that, for example, 12b is a reduced version of the overlay information 11a.

This overlay film 9 is constructed to be endless as shown in FIG. 2, and stretched so that it can be guided by four rollers 15 and moved in the direction of arrow C. Then, overlay information is selected according to the main information recorded in the main information recording section 5, and the film 9 is moved so that the selected overlay information comes to a recording position facing the photoreceptor 4.

At this time, a reduced version of the overlay information set at that recording position is displayed on the projection light source 13 and the lens 14.
The content of the reduced version is projected onto the projection window 2 by the projection device.

Therefore, according to this embodiment, a reduced version of the overlay information set at the recording position is projected and displayed on the projection window 2 of the operation section, and when the overlay film 9 is moved and the overlay information at the recording position is changed. Accordingly, the reduced version of the projection position is also changed and the display in the projection window 2 of the operation unit is automatically changed, so the operator can always accurately know the overlay information to be recorded and prevent operational errors. be able to.

Although an example in which an endless belt-like photoreceptor is used as the photoreceptor has been described, the present invention is not limited thereto, and can be similarly applied to an example in which a drum-like photoreceptor is used. Furthermore, although the overlay film 9 is configured to be rotated endlessly, it may also be wound up at both ends and moved back and forth instead of being endless.

As explained above, according to the present invention, in an electrostatic recording device having an optical forms overlay function that allows exchange of various types of overlay information, the contents of the overlay information currently set at the recording position can be changed as is. The information can be displayed on the projection window of the operation unit to inform the operator.
Misrecording of overlay information can be prevented.
