Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for connecting options such as a film feeding device, a film searching device, a sorter, etc. to a film reader/printer, copying machine, etc.

(Prior art) Conventionally, in this type of device, a conductive metal cover was fixed with screws etc. to the front of the optional connector on the main body side of the device such as a film reader, and the optional cord connector was connected to the optional connector on the main body side. When connecting to the main unit, remove the cover screws and remove the cover from the main unit, and then connect the optional cord connector to the main unit connector, so that static electricity from the operator would be discharged to the cover before connection. This prevents electrical components on the main body from being damaged by static electricity. However, as options connected to a microfilm reader or reader/printer, etc., there are options such as an automatic film feeding device, information retrieval device, automatic fish moving device, etc., and automatic film feeding devices depending on the type of film storage cartridge. There are various automatic film feeder options. When converting and using these options, if the cover is left removed from the main unit, static electricity from the operator when connecting the new option may cause electrical circuit elements for controlling the option to pass through the connector on the main unit. There was a problem that it was destroyed.

(Objective) The present invention solves the above problems and provides a connection device that prevents destruction of electrical components.

(Means for Solving the Problems) The present invention provides a swingable conductive cover on the front surface of the connector for connecting options on the main body of the device, and closes the front surface of the connector with the cover when the option is not connected to a part of the connector. It is characterized by the fact that it is made to do so.

(Example) Figure 2 shows a film leader to which the present invention is applied, 1
is a macro film, 2 is a film illumination lamp, 3 is a reflector, 4 is a condenser lens, 5 is a field lens,
6 is an imaging lens. Microfilm 1 is lamp 2
The entire image of one frame is illuminated, and the illuminated frame image is projected onto the reader optical path via the imaging lens 6. The reader optical path is formed by a first reflecting mirror 11, a second reflecting mirror 12, and a third reflecting mirror 13. Reflector 11°12.13
is inclined at 45° with respect to the optical axis of the imaging lens 6. 1
4 is a transmissive screen.

The image light of the microfilm passes through the imaging lens 6 and the first
It is projected onto the screen 14 via the reflecting mirror 11, the second reflecting mirror 12, and the third reflecting mirror 13.

Reference numeral 21 denotes an optional roll film carrier, which has a film feeding motor, a film feeding mechanism, etc., and is detachably disposed at a predetermined position between the imaging lens 6 and the field lens 5.

The roll film carrier 21 is for automatically feeding a roll microfilm stored in a film cartridge to a take-up reel using a motor.

Reference numeral 22 denotes an electric cable connected to the drive section of the roll film carrier, which supplies power and control signals to the roll film carrier.

Figure 1 shows the connector, and 23 is the cable 22.
The male connector 24 provided at the tip of the reader is connected to the male connector 23 by a female connector provided on the reader body side. The female connector 24 is connected to a roll film carrier control circuit and a power supply circuit in the electric circuit within the reader body.

A cover 25 is made of a conductive metal plate, and a conductive operating knob 26 is integrally attached thereto. The cover 25 is provided on the main body so as to be swingable in the vertical direction, and is configured to open and close the front surface of the female connector 24.

FIG. 3 shows the swinging mechanism of the cover 25.
5 has an L-shaped cross section and is supported on a shaft 28 of a conductive chassis 10' provided in the main body.

Note that the chassis 10' is grounded. cover 25
A long hole 27 is provided in the upper part of the cover 25, and this long hole is fitted into a shaft 28, so that the cover 25 can be moved in the vertical direction.

The cover 10 of the main body is provided with an opening 29 at a position facing the female connector 24, and a cover 25 is placed between the opening 29 and the female connector 24.

The operation knob 26 provided on the cover 25 is connected to the main body cover 1.
The cover 2 protrudes outward from the elongated hole 30 of the cover 2 when the operating knob 26 is moved upward in FIG.
The opening 29 where 5 has moved upward is opened, and the female connector 24 is exposed to the outside through the opening 29. When you let go of the control knob, cover 25 will fall under its own weight, and cover 2
5, the opening 29 is closed and the front surface of the female connector 24 is closed.

In the above configuration, when using a roll film by attaching the roll film carrier 21 to the reader body, manually move the operation knob 26 upward to open the opening 29 as shown in FIG. Connect the male connector 23 of No. 21 to the female connector 24 on the main body side. Since the operator's hand touches the operating knob 26 before both connectors are connected, the operator's static electricity is discharged by the cover 25, and there is no fear that the electrical circuit of the main body will be destroyed when the connectors are connected. In the above embodiment, the cover 25 may insulatively support the power cover 25 which is grounded via the chassis 10', but it is preferable that the cover 25 is grounded.

When you have finished using the roll film carrier and want to replace it with another option, connect connector 2 of roll film 21.
3 from the connector 24 on the main body. When the connector 23 is removed, the cover 25 falls under its own weight and closes the opening 29.

Next, when using a new option, install the new option in the same manner as described above, and connect the connector of this option to the connector 24 on the main body. Since the operating knob 26 is always operated when connecting a new optional connector, damage to the electrical components of the main body is reliably prevented.

FIG. 4 shows another embodiment of the cover, in which a conductive cover 125 is rotatably supported on a shaft 128, and when a conductive operating knob 126 provided integrally with the cover 125 is operated, the cover 125 is turned. The opening 29 is opened and closed by rotation.

(Effects) As described above, according to the present invention, destruction of electrical components due to static electricity caused by a worker when connecting options is reliably prevented;
The safety and reliability of the device can be improved.
