Claims

1. A lighting apparatus comprising: a power supply housing section which is composed of a cylindrical sleeve and which houses a battery cell or a contact portion, a shape of the contact portion being substantially similar to a shape of the battery cell, the contact portion being connected to an external AC adaptor;a circuit board housing section which extends from the power supply housing section and houses a circuit board, a part of a circumference surface of the sleeve being cut inwardly, a sectional area of the circuit board housing section being smaller than a sectional area of the power supply housing section;a light source housing section disposed at an end portion of the circuit board housing section;a cutout portion formed on a near side of the circuit board housing section in the power supply housing section, a part of a planar and inflexible record medium on which a hologram image or a holographic stereogram image was recorded or a part of a holder which holds the record medium being able to be inserted into or removed from the cutout portion, the cutout portion being formed at a predetermined angle corresponding to an incident angle of reference light with which a hologram was recorded; anda light source which is housed in the light source housing section and which emits light to the cutout portion,wherein an image recorded on the record medium is displayed in a state such that an end portion of the power supply housing section and an end portion of the record medium secured to the cutout portion are placed on a surface where the lighting apparatus is placed.

2. The lighting apparatus as set forth in claim 1, wherein the predetermined angle of the cutout portion is an angle of a line which connects the light source and a center of the record medium and a normal line of the record medium.

3. The lighting apparatus as set forth in claim 1, wherein the distance between the cutout portion and the end portion of the power supply housing section is substantially the same as a length of one side of the record medium.

4. The lighting apparatus as set forth in claim 1, further comprising: a sensor switch which turns on and off the power supply,wherein when the record medium or the holder which holds the record medium is inserted into the cutout portion and the record medium or the holder is brought into contact with the sensor switch, the light source is turned on, andwherein when the record medium or the holder which holds the record medium is removed from the cutout portion and the record medium or the holder is separated from the sensor switch, the light source is turned off.

5. The lighting apparatus as set forth in claim 1, further comprising: a manual control switch which turns on and off the light source, the manual control switch being manually operated.

6. The lighting apparatus as set forth in claim 1, further comprising: a sensor switch which turns on and off the power supply; anda manual control switch which turns on and off the light source, the manual control switch being manually operated,wherein when the record medium or the holder which holds the record medium is inserted into the cutout portion and the record medium or the holder is brought into contact with the sensor switch, the light source is turned on,wherein when the record medium or the holder which holds the record medium is removed from the cutout portion and the record medium or the holder is separated from the sensor switch, the light source is turned off, andwherein only when both the sensor switch and the manual control switch are turned on, the light source is turned on.

7. The lighting apparatus as set forth in claim 1, further comprising: an adjustment device which adjusts brightness of the light source, the adjustment device being disposed on the circuit board housed in the circuit board housing section, holes being formed in the circuit board housing section, the adjustment device being operated from outside of the circuit board housing section through the holes.

8. The lighting apparatus as set forth in claim 1, wherein the light source is rotatable around a sleeve perpendicular to a line which connects the power supply housing section, the circuit board housing section, and the light source housing section, andwherein a light illuminating direction of the light source is fixed at least at one position as well as a position at which the record medium is illuminated.
