A storage space 32 for storing 3 is formed. The case 5 is integrally formed of a flame retardant resin material.
As shown in FIG. 4, the front side wall 25 and the back side wall 27 each form a vertical protrusion 33 that protrudes toward the inside (the storage space 32 side) and is adjacent to each other in the walls 25 and 27. The protrusions 33 and 33 are spaced from each other by a distance K. The upper end of the protrusion 33 is below a position where a guide part of the light emitter mounting part 9 described later is inserted into the case 5.

As shown in FIGS. 1A and 2, when the light emitter mounting portion 9 is pushed into the case 5, the guide portion 39 is positioned in the case 5, and as shown in FIG. When the mounting portion 9 is slid and pulled up from the case 5, it is exposed from the case 5. The guide portion 39 has a rectangular outline as a whole corresponding to the shape of the opening of the case 5.

The terminal support portions 45 are provided on the front side and the back side of the light emitter mounting portion 9, respectively extending downward from the front side and the back side of the guide portion 39, and each lower end portion 45 a extends from the curved portion 45 b. Projecting on the side away from each other. As shown in FIG. 3, the lower end portions 45 a elastically deform the terminal support portions 45 in directions opposite to each other when the lower end portions 45 a come into contact with the inner wall of the case 5 when stored in the case 5. It is.
The terminal 43 is disposed on the opposite side surface of the terminal support portion 45, and is bent and locked through a hole 49 formed in the bent portion 45b.

Next, the assembly, usage method, and effects of the electric lamp device 1 according to the first embodiment will be described.
As shown in FIG. 4, in assembling the lamp device 1, first, the fuel cell body 3 is created. The fuel cell body 3 includes four sets of battery units 9 in which a positive electrode plate 11, a catalyst plate 13, a separation plate 15, and a negative electrode plate 17 are stacked, and the upper ends of the stacked battery units 9 are on the positive electrode plate 11 and the negative electrode plate 17. The upper end insulating tape 21 is covered and stopped so as to cover the side surface, and the lower end is stopped by the lower end insulating tape 23.

The fuel cell body is accommodated in the case while being pressed against the protrusions 33 provided on the front side wall 25 and the back side wall 27.

  Next, the terminal support portion 45 is disposed between the adjacent protrusions 33 provided on the front side wall 25 and the back side wall 27 of the case 5 so that the terminal support portion 45 is inserted into the case 5. The mounting portion 9 is mounted on the case 5, and the main body portion 37 of the light emitter mounting portion 9 is placed at the opening end of the case 5 at the position where the guide portion 39 is inserted into the case, as shown in FIGS. Deploy. In this state, the lower end 45a of the terminal support 45 is brought into contact with the inner surfaces of the front side wall 25 and the back side wall 27 of the case 5, so that the terminal support 45 is elastically deformed toward the fuel cell body 9, The terminal 43 is in pressure contact with the fuel cell body 9.

Next, the usage method of the electric lamp apparatus 1 is demonstrated. In the state shown in FIG. 1A and FIG. 2, the lower end portion of the case 5 of the electric lamp device is immersed in water or the like when in use.
Thereby, water or the like introduced into the case 5 from the water introduction hole 35 of the bottom wall 31 of the case 5 acts on the fuel cell body 3, and between the positive electrode plate 11 and the negative electrode plate 17 of the fuel cell body 9. A current flows, and the light emitter 7 is lit through the terminal 43 in contact with the positive electrode plate 11 and the negative electrode plate 17. The illuminant 7 continues to be lit for several hours or in some cases.
On the other hand, when the light is extinguished, as shown in FIG. 1B, when the light emitter mounting portion 9 is slid and pulled up with respect to the case 5, the lower end portion 43a of each terminal 43 becomes the positive electrode plate 11 and the negative electrode plate. By moving 17 upward and coming into contact with the insulating tape 21 at the upper end, the energization is cut off, and the light emitter 7 is turned off.

As shown in FIG. 1, according to the first embodiment, the upper ends of the positive electrode plate (one-side electrode surface) 11 and the negative electrode plate (other-side electrode surface) 17 of the fuel cell body 3 are not provided without providing an operation switch. The light-emitting body 7 can be turned off and turned on with a simple and inexpensive configuration in which a partial insulating tape (insulating portion) 21 is provided.
Since the light emitter 7 can be turned on and off by sliding the light emitter mounting portion 9, the operability is good.
Since it is turned on and off by the slide operation of the light emitter mounting portion 9, for example, even if there is no operation display, the user can easily recognize the operation of turning on and off.
Since the insulating tape 21 is only provided at the upper end of the fuel cell body 3, the lamp device 1 can be assembled in the same manner as in the prior art.

The terminal 43 of the light emitter 7 is in pressure contact with the positive electrode plate (one side electrode surface) 11 and the negative electrode plate (other side electrode surface) 17 by the lower end portion 45 a of the terminal support portion 45 that abuts the inner surface of the case 5. Can be always pressed against these electrode plates 11 and 17 and the insulating tape 21 at the upper end, and contact failure of the terminal 43 due to change over time can be prevented.
The main body portion 37 of the light emitter mounting portion 9 is formed with communication holes 47 on the opposite left and right side walls, so that the ion gas generated by the operation of the fuel cell body 3 can be discharged to the outside of the case. Corrosion and erosion of the terminal 43 and the light emitter 7 can be prevented.

As shown in FIG. 4, the lower end insulating tape 23 is formed in a U-shaped cross section so as to cover the lower ends of the stacked positive electrode plates 11, catalyst plates 13, separation plates 15, and negative electrode plates 17. Since it is attached, when the fuel cell body 3 is inserted into the case 5, the insulating tape 23 at the lower end can be prevented from turning over.
Since the fuel cell body 3 presses the plate-like members 11, 13, 15 and 17 from the stacking direction by the protrusions 33, the expansion when the water is immersed is prevented, and the density of generated ions is reduced. A drop can be prevented and a stable current can flow.

Other embodiments of the present invention will be described below. In the embodiments described below, the same reference numerals are given to the portions having the same operational effects as those of the first embodiment described above, and the first embodiment will be described. Differences from the embodiment will be mainly described.
FIG. 7 shows a second embodiment of the present invention. In this second embodiment, the insulating tape 21 is provided so as to be spaced from the upper end without covering the upper end of the fuel cell body 3, and as shown in FIG. In a state where the portion 39 is inserted into the case 5, the terminal 43 contacts the insulating tape 21 and is turned off by preventing the current from flowing through the terminal 43. As shown in FIG. Each terminal 43 is in contact with the positive electrode plate (one side electrode surface) 11 and the negative electrode plate (other side electrode surface) 17 in a state where the mounting portion 9 is slid and pulled up, and the light emitter 7 is turned on. is there.
In the second embodiment, the same operational effects as those of the first embodiment described above can be obtained.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
For example, the case 5 may be provided with a hole for passing a string such as a key holder or a chain.
