FIG. 4 is a sectional view of a battery house in which two batteries are connected in parallel to the battery house described in FIG. The same components as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, this battery house will be described. It is conceivable to connect two batteries in series, but if the rated voltage of the lamp is set by one battery, the rating will be exceeded and the life of the lamp will be extremely shortened. Further, when two batteries are connected in series, the battery becomes extremely dark in the case where only one battery is used. Therefore, it is better to connect two batteries in parallel to extend the battery life.

In the battery house 70, two L-shaped protrusions 72a and 72b which slide and fit into the recess 52 of the light source body 25 in the same manner as described with reference to FIG. Is provided, and can be detachably connected to the light source main body 25 of FIG.

FIG. 4 is an explanatory diagram showing a light source unit that guides irradiation light via a light guide cable. In the endoscope apparatuses according to the first and second embodiments, the battery type light source 7 that is detachably connected to the operation unit 5 of the endoscope 1A has been described. The light source unit 80 is used as a light source instead of the battery-type light source 7 connected to the operation unit 5, and guides illumination light via the light guide cable 6. Other configurations are the same as those in FIG. 1 and FIG. 2, and the description is omitted, and the light source unit 80 having a different structure will be described. 1 and 2 are denoted by the same reference numerals and described.

In FIG. 5, a light guide cap screw 19 to which the connection socket 17 of the light guide cable 6 or the connection socket 18 of the battery type light source 7 is connected is provided on the side of the operation unit 5. The light guide base 4 has a base end portion of a light guide fiber 20 for guiding illumination light fixed to a distal end portion of the insertion portion 2 (see FIG. 2).

A switch 87 for turning on and off the lamp 83 and a brightness adjustment knob 88 are provided on the upper surface of the light source unit 80, so that the on / off and brightness of the lamp 83 can be controlled.

Next, the configuration of the light source unit 80 will be described with reference to FIG.

The light source unit 80 has a connection port 81 into which the base end of the light guide cable 6 is inserted and fixed. The light source 84 supplies illumination light to the light guide cable 6, and the light source 84 Battery 85 detachably attached to
And a battery house 86 holding the battery.

In the light source section 84, the illumination light from the lamp 83 is condensed by a condenser lens 89, and is incident on the light incident end face of the light guide fiber 20.

One end of the lamp 83 is connected to a switch 87 and a brightness adjustment knob 88. By operating this switch 87, the lamp 83 is turned on and off. By operating the brightness adjustment knob 88, the brightness adjustment knob 8 is turned on.
The lamp voltage control circuit 88a connected to the LED 8 drives to control the brightness.

On the other hand, the other end of the lamp 83 is connected to a positive contact 90 and is fixed by a rivet 92. Further, the other end of the lamp voltage control circuit 88a is connected to a minus contact 91.

The contacts 90 and 91 are connected to sliding contacts 94 and 95 via rivets 92 and 93 on the surface on which the battery house 86 is mounted.

L-shaped projecting portions 96a and 96b are provided on the lower end surface of the light source portion 84, and a concave portion 97 which slides and engages with a projecting portion of a battery house described later is provided on the inner surface thereof.
a, 97b are formed.

Next, the battery house 86 removably fitted to the light source 84 will be described.

The battery house 86 includes a battery 85

A positive pole of the battery 85 is connected to a positive contact 99. On the other hand, the negative pole of the battery 85 is connected to the negative contact 100.

When the battery house 86 is fitted to the light source section 84, these contacts 99 and 100 become sliding contacts 94 and
The lamp 83 is connected to the contacts 90 and 91 of the light source unit 84 so that the energy of the battery 85 is supplied to the lamp 83.

In the battery house 86, the concave portions 97a, 9
7b, two L-shaped protrusions 101a and 101b are provided symmetrically with each other.
01b is slidably fitted into the concave portions 97a and 97b of the light source section 84, so that it can be attached and detached with one touch.

In order to use the endoscope 1A with a patient in such a configuration, the light guide cable 6 is connected to the operation section 5 of the endoscope 1A, the switch 87 of the light source unit 80 is turned on, and the lamp 83 is turned on. Is turned on.

[0086] The operation section 5 of the endoscope 1A is grasped and the endoscope 1
In the case where the battery 85 is exhausted and the battery is replaced while the battery A is being used, first, the concave portions 97a, 97b
The battery house 86 comes off by sliding the L-shaped convex portions 101a and 101b fitted into the battery housing 86. next,
The battery house 86 can be attached by sliding and fitting the L-shaped convex portions 101a and 101b of the battery house 86 into the concave portions 97a and 97b of the light source section 84.

As a result, the time for replacing the battery of the light source unit 80 can be reduced, and the operability of the endoscope 1A can be improved.

Since the light source unit 80 is provided with a brightness adjusting knob 82, the desired brightness can be adjusted by operating the knob.
By increasing the voltage applied to the lamp 83, the amount of light can be increased. However, when the voltage of the lamp 83 is increased, the power consumption of the lamp 83 increases, and
5 will be consumed, but if it is necessary for observation, the advantage of brightening is greater.

By the way, when the consumption of the battery 85 is severe, a higher capacity battery is required. Therefore, it is possible to use the endoscope for a longer time by connecting two or more batteries 85 in parallel with each other and increasing the capacity by connecting them in parallel.

FIG. 7 shows the battery house 8 described with reference to FIG.
FIG. 6 is an explanatory view showing a battery house 110 in which two battery holders are vertically accommodated and batteries are connected in parallel. The same components as those in FIG. 6 are denoted by the same reference numerals, and description thereof is omitted. Hereinafter, the battery house will be described.

In the battery house 110, the batteries 85a, 85a are stored in the battery holders 111a, 111b, respectively.
85b is accommodated and the battery capacity is doubled.

In order to connect the batteries 85a and 85b in parallel, the contacts 9 connected to the sliding contacts 94 of the light source unit 84
9 is connected to the positive poles of the batteries 85a and 85b, while the contact point 100 is connected to the negative poles of the batteries 85a and 85b.

The contacts 99 and 100 connect the battery house 110 to the sliding contacts 94 and 95 as a power source for the lamp 83, conduct with the contacts 90 and 91 of the light source 84, and connect the lamp 83 to the energy of the batteries 85 a and 85 b. Is supplied.

As a result, the capacity of the battery is doubled, so that the battery can be used with twice the observation time.

When the light amount is increased by adjusting the brightness adjustment knob 88 of the light source section 84, the endoscope can be used longer as much as the battery capacity is increased.

Further, if the light source unit 80 is large enough to be stored in the breast pocket of the surgeon who operates the operation unit 5 of the endoscope 1A or the pocket beside the white coat, further portability can be realized. .

Further, in the endoscope apparatus 1 of the present embodiment, the light source unit 80 is described in which the battery capacity of the battery house 86 detachably connected to the light source unit 84 is doubled. However, the present invention is not limited to this. For example, a configuration may be adopted in which a light source unit configured by connecting the battery capacity three times or more in parallel is used.
