Normally, w is connected to terminal Nc, and connected to terminal NO by the electromotive force of electromagnetic coil L (details will be described later). Switch Sw, Oi terminal Nc, No, Q
Tfi coil I constitutes a relay 31. The contact terminal is connected to the terminal 27a1 of the recessed connector 27.

The base of the transistor Trl is connected to the external controller 32 via a contact E and a resistor R1.

Contact point E is connected to terminal 27a2 of recessed connector 27. The collector of the transistor Tri is connected to the voltage '6Q N o,1 via a contact F and a resistor R2. The emitter of transistor Tri is connected to ground X. The transistor Tri turns ON when the external controller 32 generates an H output voltage, and turns OFF when the external controller 32 generates an L output voltage. The collector of the transistor Tr2 is connected to the power supply No. 2, and the base is connected to the contact F via a resistor R3. The emitter of the transistor Tr2 is connected to the if Ljl coil L. The transistor Tr2 turns OFF when the external controller 32 generates an H output voltage, and turns ON when the external controller 32 generates an L output voltage.

A keyboard 26 is connected to the external controller 32. By pressing the key 26a of the keyboard 26, an L output voltage is generated in the external controller 32, turning off the transistor Tri and turning on the transistor ↑r2. When the transistor Tr2 is turned on, the emitter current It of the transistor Tr2 is caused to flow through the Tit%H coil. For this reason, the electromagnetic coil L is energized and the changeover switch 3w is connected to the terminal No. Therefore, the dimming circuit 24 is connected to the epi-illumination lamp 3a. Further, by pressing the key 26b, an H output voltage is generated in the external controller 32, and the transistor Tri is turned on.
Also, the transistor Tr2 is turned off.

Emitter current when transistor Tr2 is turned off!
, is cut off, the electromagnetic coil does not generate electricity, and the changeover switch Sv is connected to the terminal Nc. The dimming circuit 24 is therefore connected to the transmitted illumination lamp 3b.

It is connected to ar, 29 az. Along with the connection between the concave connector 27 and the convex connector 28, the connection terminal 2

bi, thereby connecting the external transformer 28 to a light source for transmitted illumination. Further, a connection surface 29b is arranged inside the convex connector 29, and the connection surface 28b is used as the connection control section described above. That is, the recessed connector 27
and the convex connector 28, the terminals 27a+, 2
7az is connected to the connection surface 29b, and the contact point E is short-circuited through this connection. Contact is closed due to short circuit, H
Since the L voltage is generated at the contact E, the transistor Tri is turned OFF and the transistor Tr2 is turned ON regardless of the command from the external controller 32. Emitter current ■ by turning on transistor Tr2
is caused to flow through the electromagnetic coil to generate electricity in the electromagnetic coil L, and the switch Sw selects terminal NO by the electromotive force.

This connects the dimming circuit 24 to the epi-illumination lamp 3a. Connection with the concave connector 27 and the convex connector 30 is made during simultaneous epi-illumination and transmission illumination, and the connection is removed when automatic switching between epi-illumination and transmission is performed.

Next, we will explain the operation of the circuit.

In automatic switching between transmitted illumination and epi-illumination, press key 26 on the keyboard 26 to switch from transmitted illumination to epi-illumination.
Press a, thereby generating an L output voltage in the external controller 32, turning off the transistor Tri, and turning on the transistor Tr2. When the transistor Tr2 is turned on, an emitter current l flows through the electromagnetic coil, and an electromotive force is generated in the electromagnetic coil. For this purpose, the changeover switch Sw is switched to the terminal No. and connected to the terminal No. Therefore, the dimming circuit 24 is connected to the epi-illumination lamp 3a to turn on the lamp 3a.

To switch from epi-illumination to transmitted illumination, press Keyboard 2

turns on, and transistor Tr2 turns off. By turning off the transistor Tr2, the emitter current I is cut off, and the electromotive force in the electromagnetic coil disappears. For this purpose, the changeover switch Sw is switched to the terminal Nc and connected to the terminal Nc. Therefore, the dimming circuit 24 is connected to the transmitted illumination lamp 3b to turn on the lamp 3b.

To simultaneously perform transmitted illumination and epi-illumination, the second connector 29 is connected to the first connector 27.

As a result, the terminals 27b+ and 27bz are connected to the terminals 30a, 30at, respectively. For this purpose, the external transformer 28 is connected to the filtered illumination lamp 3b, and the transformer 28 lights the transmitted illumination lamp 3b. Further, due to the connection of the connector, the terminals 27a+ and 27at are connected to the connection surface 2sb, so that the contact point and the contact point E are short-circuited via the connection surface 29b. As a result, L':4 pressure is generated across the contact, and the external controller 320
Related to the command (transistor Tri turns OFF, transistor Tr2 turns ON. Transistor Tr2

Turn on a.

According to the above embodiment, when switching between epi-illumination and transmitted illumination, the connection switching circuit connects the dimmer circuit to any of the light sources by pressing each key on the keyboard, so that the illumination is automatically There is no need to remove one connector from the light control device and connect the other connector to the light control device, which takes time and effort, as shown in the conventional section.

Further, although it has been shown that the dimming circuit 24 and the connection switching circuit 25 are arranged inside the w4m mirror zero body 7, the present invention is not limited to this.
A dlLm main body 7 is provided with a dimmer and a connection switching device connected to the dimmer, and as shown in the conventional example (see FIG. 3), epi-illumination is transmitted via the first cord 4a. Connect the first connector 5a connected to the light source for transmitted illumination and the second connector 5b connected to the light source for transmitted illumination via the second cord 4b to the connection switching device, and press the key on the keyboard connected to the connection switching device. In this case, the connection switching device and the keyboard constitute the above-mentioned connection means.

Furthermore, the control device connects the connection switching device to the connection switching device, and connects the connector for connecting to the external transformer to one of the light sources, and simultaneously connects the other light source to the light control device. Needless to say, it is necessary to control the illumination and perform simultaneous epi-illumination and transmitted illumination.

(Effect of the invention) According to the above-mentioned present invention, the second! When the ll light device is connected to the i3 over-illumination light source, the control means controls the connection means so that the 1st tA light device is connected to the epi-illumination light source accordingly. It is possible to obtain an illumination device that performs simultaneous illumination.
