As a result, the lamp portion 21 of the lamp device 2 (the lamp device main body 23) protrudes from the side of the bottomed cylindrical body 12 from which the lid is detached (left side in FIG. 1). At this time, the cylindrical body 27
Is left at the opening edge of the bottomed cylindrical body 12 when the lid body 11 is separated from the bottomed cylindrical body 12.
The lamp device main body 23 is prevented from further projecting in contact with a, that is, the lamp device 2 (the lamp device main body 23) from falling off the bottomed cylindrical body 12.

When the micro switch 5b is turned on, FIG.
As can be seen from the circuit diagram, the power supply 25a including one 3V cylindrical lithium battery or AA battery series 3V circuit turns on the miniature lamp 21a. That is, miniature bulb 2
1a is automatically turned on, and the cover detached side, that is, the miniature bulb 21a
Is illuminated, that is, the front (left side in FIG. 1) is irradiated with light.

It is possible to use the lamp as a lantern by suspending the miniature lamp 21a downward at an appropriate position in such a use state (the state shown in FIG. 1), but more effectively. To enable use as a lantern, for example, the following configuration may be used.

The peripheral wall surface of the lamp portion 21 is formed of a translucent member, and the translucent front plate 21 is attached to and detached from the front end of the lamp V21 by, for example, a screw type as shown in FIGS. Configure freely.

According to this, in the use state (the state shown in FIG. 1), one end of the translucent front plate 21c is removed from the front end of the lamp part 21 and the reflector 21b is used to discharge light from inside the lamp part 21 to the lamp. Acetic acid can be irradiated on the front surface side and the peripheral wall surface side of the part 21, so that it can be used more effectively as a lantern.

Assuming that once used as a lantern and then used again as a flashlight, it is preferable to join the reflector 21b to the front plate 21c in order to prevent the reflector 21b from being lost. In the configuration, the front plate 21c to which the reflector 21b is joined may be once removed from the front end of the lamp 21 and may be mounted on the front end of the lamp 21 again in a state where the direction is reversed. For this reason, in the examples of FIGS. 1 and 2, male threads are cut on both left and right sides around the front plate 21 c. According to this, since the reflector 21b is present, the light from the miniature bulb 21a is more radiated on the peripheral wall side than on the front side of the lamp part 21, so that it can be more effectively used as a lantern. .

The configuration enabling effective use as a lantern is not limited to the above-described configuration. For mounting the miniature light bulb 21a, a normal screw-in socket may be used, but a bayonet-type socket may be used. According to the bayonet-type, loosening due to vibration or the like like a screw-in type, poor contact, etc. As a result, the reliability is improved and the mounting operation is simplified.

Although the flashlight of the present invention is mainly suitable for disposable use, the lamp portion 21 is returned into the bottomed cylindrical body 12 against the pressing force of the coil spring 24 even in the use state of FIG. If the state is maintained, the microswitch 25b also returns to the OFF state, and the consumption of the power supply 25a can be interrupted. Thereafter, except for the load against the pressing force of the coil spring 24, the miniature bulb 21a is automatically turned on again, and the use as a flashlight can be continued.
