(When the connection detection signal of the past reception is received, the priority of the peripheral device corresponding to the connection detection signal of the current reception is determined, and the nth peripheral device with the highest priority is always selected.) The term 1HjY refers to the presence of a control change means for executing control for transmitting and receiving various signals, giving priority to peripheral devices with lower performance.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a microfilm reader/printer to which the present invention is applied.

The front side of this microfilm reader/printer has a projection screen 1 for enlarging and projecting a microfilm image, and an operation panel 2 equipped with various operation keys.

Then, as shown in the figure, a cartridge film 5 is loaded with the film handler 3 and the page (nurturer 4) attached, and a microfilm image is projected and an image is formed on the image forming carrier.

The internal structure of this microfilm reader/printer is roughly divided into a film setting unit 6, a projection unit 7, a scanning light guide unit 8, and an image forming unit 9, as shown in FIG.

In the film setting unit 6, a condenser lens 11, a film press plate 12, and a lens case 13 are arranged in order from the light source 10 side on the optical path of the light emitted by the light source 10Ifi.

When a microfilm is attached to the film holding plate 12, the emitted light from the light source 10 is focused by the condensing lens 11'c and irradiated onto the back side of the microfilm on the film holding plate 12. The emitted light that has passed through the film is incident on the lens case 13.

The lens case 13 can be used with a lens having a magnification selectively selected from among lenses having various magnifications;
The incident radiation light is sent to the projection unit 7 at a rate of 18 of the attached lens.

Projection 7: When the rotating mirror 14 does not block the optical path of the light emitted from the lens attached to the lens case 13, the microfilm image is projected onto the projection screen 1 via the mirror 15 and the mirror 1G. .

In addition, when the rotating mirror 14 blocks the optical path of the light emitted by the attached lens of the lens case 13, the scanning light unit 8
A microfilm image is projected onto the photosensitive drum 21 of the image forming unit 9 through mirrors 17, 18, and 19.

The image quality forming unit 9 of the reader/printer shown in FIGS. 1 and 2 is constructed as shown in detail in FIG. 3.

In this image forming unit 9, 22 is a unit main body, a paper feed cassette 23 is installed on the lower front side of the unit main body 22, and a paper output tray 24 is installed above this. There is. A photoreceptor drum 21, which is a carrier, is disposed approximately in the center of the unit main body 22, and above the photoreceptor drum 21, a shutter device IW 2 for blocking the scanning light from the scanning light guide unit 8 is provided.
5 J3 and its drive solenoid 26 are provided.

Around the photoreceptor drum 21, a charger 27 for the belt', a developing device 28, two pre-transfer static eliminators, a charger 30 for transfer,
Stripping device 31, cleaning device 32, and static elimination lamp 33
etc. are arranged.

At the bottom of the unit main body 22, the paper that is automatically taken out from the paper feed force tray 1-23 via the paper feed roller 34 is discharged through a glyph acid section between the photosensitive drum 21 and the transfer charger 30. A paper conveyance path 36 leading to a tray 37 is formed.

A registration roller 37 is disposed on the upstream side of the image forming section 36 in the paper conveyance path 35, and a heat roller 38 and a paper discharge roller 39 are disposed downstream as a fixing device.

When the photosensitive drum 21 is driven θ' in the direction of the arrow a in the figure, it is first uniformly charged by the charging charger 27;
The scanning light from the scanning light guide unit 8 is sequentially imaged on the photoreceptor drum 21, and an electrostatic latent image is formed. The image is developed and made visible by the device 28, and sent to the transfer charger 30 side. On the other hand, the paper fed by the paper feed cassette 23 is
The image supplied by the registration roller 37 and previously formed on the photosensitive drum 21 is transferred by the transfer charger 30 . The paper to which this image has been transferred is

5 and is guided to the heat roller 38, where it is rotated ``4''.
'After the image is fused and fixed, it is discharged to the paper discharge tray 24 by the IJI paper roller 39. On the other hand, after the image is transferred onto the paper, the residual image on the photoreceptor drum 21 is removed, so that it is ready for the next copying operation.

The developing bag layer 28 includes a first developer@O-ra 28a and a second developer I &
It has a D-roller 28b, and these developing rollers 28a and 2
8b can be selectively driven to develop both negative recorded microfilm and positive recorded microfilm into positive images. However, the first developer 28a performs positive-positive development, and the second developer 28a performs positive-positive development.
8b is designed to perform negative-positive development.

In a development mode that performs a positive-positive decrease (hereinafter referred to as the P-P phenomenon), increasing the exposure amount of the light source lamp of the light source 10 brightens the image formed on the paper, and decreasing the exposure amount brightens the image formed on the paper. The image formed on the paper becomes dark.

In addition, a development mode (hereinafter N-
0yAelG! In this mode, when the exposure amount of the light source lamp of the light source 10 is decreased, the image formed on the paper becomes brighter, and when it is increased, the image formed on the paper becomes darker.

Historically, in one embodiment of the present invention, when a film handler 3 or page search ll-4 is installed and electrically connected in the system configuration of the reader/printer main body, a connection detection signal is generated. C. Film handler installation signal (
F-AVAIL) and page searcher installation signal (S
-AVA I L> is provided.

Further, there is a control change means for selecting a priority panel when F-AVA I L and 5-AVA I L are flashed.

This system'1 changing means is as shown in 4th UXU,
When AVAIL and σ5-AVAIL are both OFF, the reader/printer's controller panel functions. Then, F-AVA I L is turned on and 6.5-AVA I L/) < 0FF (1) Mayo T
Ah, the control panel on the reader/printer itself will function as expected.

and L'3, 5-AVAIL is ONr, which makes the control panel of Page Searcher 4 function, and 5-AVAIL and (/F-AVAIL are both ONr).
Even if N is selected, the control panel of Page Searcher 4 will function.

In short, in this example, C is page searcher 4.
When installed, this installation will have top priority.

(When the page searcher 4 is performing a page search of the cartridge film 5, the reader
Print operations can be executed on the printer body. C. After the page search is completed, the reader printer itself will perform a printing operation.

In this way, depending on the priority, the control panel of τ page searcher 4 and the control panel of reader/printer are set to IJJJ 3! Since 'tR is performed, erroneous judgments by the A verator and erroneous operations due to carelessness are avoided.

Further, in this embodiment, the film handler 3
As shown in FIG. 5, there is a connection terminal 40 on the side panel 42 side opposite to the side where the cartridge film 5 is loaded. I can smell it. This connection terminal 40 is used to open the side panel 42 and turn off the power to the main body of the reader/printer whose insertion suppression by the pin 41 is released.
F? It also has the function of Then, this connection terminal 40
only when the reader/printer is turned off,
For the reader/printer body, film handler 3
Attach the line page searcher 4 or use fll [f
We are making it possible to do this.

In other words, when connecting or disconnecting the film handler 3 or page surger 4 connector to the reader printer main body, the power must be turned off, and the power must be turned on.
If t' exists, it is possible to prevent electrical components from being damaged by the rush current generated when each =j connector is attached and detached. Moreover, since the connecting terminal 404 cannot be touched with the hands when the power is turned on, the risk of electric shock is avoided.

Also, in this embodiment, there is a means for generating a CARTRIt)GE signal to indicate when the cartridge film 5 has been loaded onto the film handler 3.

Furthermore, when the cartridge film 5 is handled by the film handler 3 as shown in FIG. 6, the CARTRI
DGE signal 1fi OF F toi,,t'), the timer of the reader/printer is started at cholera reception, and the timer of the reader/printer is activated for a certain period of time j+l! There is a means for turning off the light source 10 when a time error/output occurs in the past timer.

Also, for the film handler 3, the cartridge
When the film 5 is loaded, the CARTRIDGE signal is turned ON, and there is a means for receiving this signal and turning on the light source 10.

Also, even if the CARTRIDGE signal turns OFF and the timer of the C reader/printer is started in response,
When the cartridge 1 is loaded at time t2 before the elapse of the predetermined time t1, the count by the timer is canceled and the light source 10 remains on.

Further, in this embodiment, the film handler 3
Furthermore, if the page searcher 4 is in operation, there is a means for emitting a signal indicating this, and there is a configuration in which the print operation of the reader/printer body is prohibited as soon as the signal A is output.

In addition, in this embodiment, C is a page search function on the reader/printer body! Indicates that 7-4 is electrically connected - = IP/S connection signal and page search t? - When the P/'S' power-on signal indicating that the power of the printer is turned on and at least one of them is ON, the specified input/output means of the operation section of the reader/printer main body This is so that the system stops functioning.

For example, as shown in the schematic circuit diagram of FIG. 7, when a P/S connection signal is issued, the receiving terminal 51 on the
The virtual contact 53 with the S-side sending terminal 52 is closed.

When the virtual contact 53 is open, the input side of the impark 54 is in a high impedance state, and even if the virtual contact 53 is closed, the P/S power-on signal from the inverter 55 is not applied to the sending terminal 52 (in other words, The input side of inverter 54 is in a high impedance state.

In any case, if the input side of the inverter 54 is in a high impedance state, the output of the inverter 52 is at a low level.

When the virtual contact 53 is closed by the P/S connection signal, when the P/S power supply (acceptance signal) is applied to the sending terminal 52 from the inverter 55, the input side of the impark 52 becomes a low impedance state, so the inverter 52 output reaches high level.

In this way, since the P/S connection signal and the P/S power-on signal are on a common signal line, the control program for communication is converted into Mrla and 1q.

Also, this - real f! 91, if an abnormality occurs in the reader/printer body such as paper jam, no paper, or insufficient toner in the developer, peripheral equipment such as page searcher/1 etc. 511!7:; There is a configuration in which an alarm is displayed for the occurrence of the abnormality, and the details of the abnormality are displayed on the reader/printer main body.
