Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image forming apparatus that controls image forming means in an electrophotographic apparatus or the like that uses a plurality of types of transfer bodies such as plain paper and plastic films.

[Technical background of the invention and its problems] Image forming devices such as photographic devices and printers use various types of transfer material, such as plain paper or plastic film, with different materials and thicknesses, depending on their use. Generally, the transfer device for the transfer body, the image forming means such as the transfer charger, etc. have fixed electrically or mechanically set values to suit the characteristics of each transfer body.

For this reason, for example, even if you try to obtain an image on a plastic film using a device that normally uses plain paper as a transfer medium, the setting values of the image forming means are set for plain paper. Transfer defects may occur, or the plastic film may change in quality due to heating during fixing, making it impossible to obtain a good quality image.In the end, the characteristics of the transfer material are limited, and the characteristics may vary for a particular transfer material. This method has the disadvantage that a specific image forming apparatus must be prepared individually depending on the type of image forming apparatus.

[Purpose of the invention]

This invention was made based on the above circumstances, and it is possible to obtain good images on each transfer body even if multiple types of transfer bodies with different characteristics are used with a single image forming apparatus. An object of the present invention is to provide an image forming apparatus whose functions can be expanded.

[Summary of the invention]

In order to achieve the above object, the present invention provides a detection means for detecting information regarding the transfer body.

By providing a control device that controls the image forming means based on the detection results from the detecting means, it is possible to form good images on a plurality of types of transfer bodies having different characteristics.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Sheet supply section (1) of the main body (not shown)
0) includes sheet-like transfer bodies (1) of different materials, sizes, and thicknesses such as plain paper or plastic films
It is possible to install many types of containers (12) in which each type of container 1) is sealed. And these various types of containers (12)
is made of vinyl processed paper, has an opening part (12c) for separating the lid part (12a) from the main body part (12b), and has information on the transfer body (11) in the container (12) on the side thereof. A label (1
3) is attached. On the other hand, sheet supply section (10)
is equipped with a supply roller (14) and a container (12).
The label (1) is placed opposite the label (13) when attached.
3) A photocoupler (17) is provided as a detection means for detecting the above information and inputting it to the microcomputer (16a) of the control device (16). Here, the control device (1
6) according to the instructions of the microcomputer (16a),
Electrical system control device (16b) and mechanical system control device (1
6c) controls the entire main body (not shown). In other words, the electrical system control device (16b) controls the image forming means (not shown), such as a charging charger and an exposure lamp, other image forming means, such as a transfer charger (18a) and a peeling charger (18b), and also a fixing heater ( The mechanical system control device (16c) controls the applied voltage and drive timing to the photoreceptor drum (20a).
21) and a drive or conveyance guide (22a) for an exposure device or a developing device (not shown).

(22b) and (22c), the pressure between the fixing rollers (20), etc. are controlled.

However, to start copying, the necessary transcription body (11
) is a plastic film, for example, after cutting off the opening part (12c) of the corresponding container (12) and removing the lid part (12a), the sheet supply part (10
) When the container (12) is attached to the container (12), information regarding the transfer body (11) such as material, heat resistance, stiffness, thickness, etc. is detected from the gala label (13) by the photocoupler (17). When the information is input to the microcomputer (16a), information regarding the thickness and stiffness is input to the mechanical system control device (16c).
6c) transfers the transfer member (1) to the photoreceptor drum (21).
A conveyance guide (22b) is used to make the conveyance angle appropriate in 1).
The inclination of the fuser roller (20) is adjusted and the appropriate pressure between the fuser rollers (20) is set. At the same time, information such as material, heat resistance temperature, and thickness is sent to the electrical system control device (16b).
, the appropriate applied voltage values of the transfer charger (18a), peeling charger (18b), and fixing heater (20a) are immediately set to "." After that, the operator presses the copy button (not shown). When the photosensitive drum (21) is turned on, a toner image is formed on the photosensitive drum (21) as the photosensitive drum (21) rotates.
The transfer body (11) is supplied to the photosensitive drum (21) by the conveyance guide (22b), which is set at an appropriate angle.The transfer body (11) is all set to suit its characteristics. A copy image is formed via a transfer charger (18a), a peeling charger (18b), and a fixing roller (20). Then finish making the required number of copies,
Next, for example, when using plain paper as the transfer body (11), a container (1) in which the corresponding transfer body (11) is stored.
2) is replaced as a container for storing plastic film and attached to the sheet supply unit (10). As a result, new information regarding the characteristics of the plain paper is detected from the label (13) by the photocoupler (17). Then, according to this new information, the control device M (16) controls the transport guide (
22b), the pressure between the fixing roller (20), the transfer charger (18a), and the peeling charger (ta).
b) The applied voltage value of the fixing heater (20a) is reset to a value suitable for plain paper. Thereafter, in order to obtain a copy image, the operator turns on a copy button (not shown).

In this way, depending on the characteristics of the transfer body (11).

The angle of the conveyance guide (22b), the pressure between the fixing rollers (20), the voltage applied to the transfer charger (18a), etc. can be automatically set to appropriate values, making it suitable for multiple types of transfer materials with different characteristics. Good copy images can be obtained on a plurality of types of transfer bodies using a single image forming apparatus without causing transfer defects, fixation defects, or deterioration of the quality of the transfer bodies.

Note that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, the image forming apparatus may be one that performs latent image transfer, and the transfer body may be coated with a photosensitive material to suit this purpose. It may be something. Information regarding the transfer body may also include its size, date of manufacture, etc. The recording method may also be magnetic, using a magnetic head as a detection means, or the information may be recorded on a card or the like. A card reader may be provided on the control panel as a detection means, and the information may be read from the card reader when replacing the transfer body.

〔Effect of the invention〕

As explained above, according to the present invention, information regarding the transfer body can be detected by the detection means, and further, the setting value of the image forming means can be automatically set to an appropriate value according to the detection result. Even when it is desired to obtain images on multiple types of transfer bodies with different characteristics, there is no need for image forming apparatuses tailored to the characteristics of each transfer body as in the past, and a single image forming apparatus can be used. Even in such cases, it is possible to obtain a good image on each transfer member without degrading the image due to poor transfer, poor fixing, etc., and the functions of the image forming apparatus are expanded.
