ようになつている。(Prior Art) Generally, electric megaphones are known which are composed of a speaker section and an amplifier section, and a battery case section is provided at the rear of the amplifier section. In such electric megaphones, batteries can be loaded into the battery case by removably inserting a battery holder containing a plurality of batteries into the insertion holes in the battery case. There is.

ることも必要である。(Problem to be solved by the invention) However, although the battery holder used in such electric megaphones is usually molded from synthetic resin, electric megaphones are frequently carried around and are susceptible to vibrations, shocks, etc. A high-output electric megaphone requires a large number of batteries, and the total weight of the batteries is heavy, so it must be strong enough to store and hold them. Furthermore, since electric megaphones are carried everywhere, it is necessary to be able to easily replace the batteries with good operability at any location.

用いることが考えられる。 By the way, in Utility Model Publication No. 55-35728,
A synthetic resin sleeve having elasticity for holding a battery is housed inside the case body 8, and a part of the side wall of the sleeve housing at least one battery forms a wavy curved surface with a continuous cross section. In addition, a battery container has been proposed in which the wavy curved surfaces protrude and separate the batteries from each other so that the batteries can be stored and held between the curved surfaces and the inner wall surface of the case body. It is conceivable that it could be used as a battery holder for a megaphone.

言えない。 However, such battery containers have a complicated structure, with a sleeve inside the case body, and both ends of the case body are open, so when replacing the battery, only the battery or the battery and the sleeve may fall out. Moreover, since the case body itself is cylindrical, its mechanical strength cannot be said to be sufficient.

本考案は、かかる点に鑑みてなされたもので、

る。 This invention was made in view of these points,
An electric megaphone that has sufficient mechanical strength even when a large number of batteries are required and the total weight of the batteries is heavy, and that can be easily attached and detached without dropping the batteries when replacing the batteries. The purpose is to provide a battery holder.

ンプ部３とからなつている。 In Figure 1, which shows the entire electric megaphone, 1 is a high output (30W) electric megaphone, powered by a single dry cell battery.
It is made up of 10 power supplies, a speaker part 2 in the shape of a rattle, and an amplifier part 3.

また、後部に端子盤部１２がそれぞれ配設されて
いる。 The amplifier section 3 consists of a separate battery case section 4 and an amplifier case section 5. The battery case part 4 has an opening/closing lid 6 pivotally attached to the rear thereof so as to be openable and closable, and legs 7 erected at the lower part. On the other hand, the amplifier case section 5 has a heat dissipation section 8 (heat dissipation plate), an operation panel section 9, a wireless antenna 10, a microphone hanger 11, etc. on the top surface.
Furthermore, terminal board sections 12 are provided at the rear.

ずつ収納されている。 The battery holder 18, which is removably inserted into the insertion hole 4a of the battery case part 4, is made of synthetic resin, and has a plurality of cylindrical battery storage parts 18a (five in the drawing) with one end open and the other end closed. are arranged in a semicircular arc shape. Two batteries 19 are stored in each battery storage section 18a.

引き出すことができる。 An outward facing collar portion 18b is provided on the opening side of the battery storage portion 18a and between each battery storage portion 18a. This flange portion 18b increases the mechanical strength of the opening side portion, which has poor mechanical strength, thereby increasing the mechanical strength of the battery holder 18 as a whole. Further, by placing a fingertip on the flange portion 18b, the battery holder 18 can be easily pulled out from the battery case portion 4.

の間の寸法誤差も吸収される。 The outer circumferential wall 12 of the battery holder 18 is integrally formed with protrusions 18d (six in the drawing) at appropriate locations on the opening side, and the tips of the protrusions 18d elastically contact the inner circumferential wall of the battery case portion 4. It's becoming like that. This compensates for the difference in inner diameter that occurs in the battery case portion 4 due to the draft angle of the mold. That is, the battery holder 18 is elastically supported by the inner circumferential wall of the battery case part 4 via the protrusion 18d, and so-called looseness between the battery case part 4 and the battery holder 18 is eliminated. In addition, since the battery holder 18 itself is made of synthetic resin and exhibits some degree of elasticity, dimensional errors between the battery case portion 14 and the battery holder 18 are also absorbed.

Not only does it provide sufficient mechanical strength even when the battery is replaced, but it also has good operability when replacing batteries.
Can be attached and detached. In addition, a center hole is provided at the closed end of each battery compartment to expose the battery terminals, which prevents batteries from falling when connecting or replacing batteries without reducing mechanical strength. It is possible to achieve both.
