Abstract

PURPOSE:To reduce the number of parts and cost by providing an operating means arbitrarily switching a residual secondary battery display and an illumination display for showing the charging current of a solar battery with the opening/closing of a barrier. CONSTITUTION:An operational part 1 opening/closing the barrier 6, a solar pack 3 having the solar battery and a display panel 2 are provided on a camera main body 4. When the operational part 1 is slid to the left at the time of photographing, the barrier 6 is opened to the right along a guiding groove 5. The leftmost part, of the operational part 1 energizes an opening/closing detecting switch 11 and it generates an ON signal. On the display panel 2, the residual second current is displayed at a constant interval in response to the ON signal. When charging is wanted after the completion of photographing and the barrier 6 is closed, the detecting switch 11 is turned off to generate an OFF state detecting signal. On the display panel 2, the illumination display for showing the discharging current of the solar battery is displayed at the constant interval in response to the OFF state detecting signal.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly, to a solar pack equipped with a solar cell for improving the operation of the secondary battery residual amount display and the illuminance display showing the charging current of the solar cell. It is related to the camera.

[0002]

2. Description of the Related Art A conventional camera of this type is configured to arbitrarily switch between a display of a remaining amount of a secondary battery and an illuminance display showing a charging current of a solar battery by operating a switching button operating portion.

[0003]

However, in the above-described conventional camera, the opening / closing operation section of the barrier or the opening / closing operation section of the solar pack displays the remaining amount of the secondary battery and the illuminance display showing the charging current of the solar cell. Since it is separate from the operating member, the operability is complicated, and since the number of parts increases, there is a problem in that much cost is required.

The present invention is intended to solve the above problems. That is, the present invention eliminates the dedicated operation unit for switching the remaining amount display and the illuminance display, and instead switches the display in conjunction with the opening or closing of the barrier or the solar pack, thereby reducing the number of parts and reducing the cost. An object of the present invention is to provide a camera that can be down.

[0005]

In order to achieve the above object, the present invention provides a secondary battery residual amount display and a solar cell charging current by opening and closing a barrier in a camera having a solar pack having a solar cell. A switching operation means for arbitrarily switching the displayed illuminance is provided.

[0006]

According to the present invention, a camera having a solar pack equipped with a solar cell is provided with a switching operation means for arbitrarily switching between a secondary battery remaining amount display and an illuminance display showing the charging current of the solar cell by opening and closing a barrier. Therefore, it is possible to eliminate the dedicated operation unit for switching the remaining amount display and the illuminance display, the number of parts is reduced, and the cost can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a first embodiment of the present invention, in which a solar pack having a solar cell on the back side is in a closed state.

The camera body 4 is provided with an operation unit 1 for opening and closing the barrier, a solar pack 3 and a display panel 2.

FIG. 2 is an enlarged front view of the camera of FIG. 1 when the barrier is closed, and FIG. 3 is an enlarged front view of the camera when the barrier is opened.

2 and 3, 5 is a guide groove, 6 is a barrier, 7 and 8 are stoppers, 9 is a drive lever, 10 is a tension spring, and 11 is an open / close detection switch.

That is, as shown in FIG. 3, when the operator wants to take a picture, the operating section 1 is slid in the direction A so that the barrier 6 opens rightward along the guide groove 5. At the same time as the barrier 6 is opened, the leftmost end of the operation unit 1 is the open / close detection switch 1
When the switch 11 is biased to 1, the switch 11 generates an ON signal, and the display panel 2 displays the remaining amount of the secondary battery in a certain time according to the ON detection signal. On the other hand, when the barrier 6 is closed when charging is desired after the end of shooting, the detection switch 11 is turned off, an OFF state detection signal is generated, and the display panel 2 charges the solar cell for a certain period of time according to the OFF state detection signal. The illuminance display which shows an electric current is shown.

FIG. 4 shows a circuit diagram of this embodiment. When the open / close switch 11 urges the leftmost end of the operation unit 1, the switch 11 sends an ON state detection signal to the display IC 14, recognizes the detection signal, and the voltage detection circuit 15 causes the voltage of the secondary battery 18 to be detected. To detect. According to the detection signal, the display IC 14 displays the secondary battery 1 on the display panel for a certain period of time.
The remaining amount of 8 is displayed. On the other hand, the display IC 14 recognizes the OFF state detection signal, the current detection circuit 16 detects the charging current of the solar cell 12, and the display IC 14 indicates the charging current of the solar cell on the display panel for a certain period of time according to the detection signal. The illuminance display is shown.

Reference numeral 17 is an LCD, and 19 is a backflow prevention diode.

FIG. 5 is a perspective view showing a second embodiment of the present invention, showing a case where the solar pack 3 provided with solar cells is opened and charged.

That is, as shown in FIG. 5, when the solar pack 3 is in the open state, the sensor 13 provided on the back surface of the main body 4 has a certain distance value or more set between the solar pack 3 and the main body 4. When released, an ON-state signal is generated, and the remaining amount of the secondary battery is displayed on the display panel 2 for a certain period of time according to the signal. On the other hand, when the solar pack is closed and returned to the normal state, the sensor 13 generates an OFF state signal, and according to the signal, the display panel 2 displays an illuminance display indicating the charged battery of the solar cell 12 within a certain time.

[0016]

As described above, according to the present invention,
In a camera having a solar pack equipped with a solar cell, since it has a switching operation means for arbitrarily switching between a secondary battery remaining amount display and an illuminance display showing the charging current of the solar battery by opening and closing a barrier, the remaining amount display and Since the illuminance display can be arbitrarily switched by one operating means, the number of parts can be reduced, the switching operability can be improved, and the cost can be reduced.
