The radio wave frequency switching device 1L is a device set at various frequencies, and the frequency of the radio as a terminal changes by replacing the device. For example, when the radio frequency switching device of AM1600khz is set, the voice guidance information recorded in the transmission device can be obtained when the radio dial is set to 1600khz. If the radio frequency switching device of 1000 kHz is set at the same place, another voice guidance information recorded in the transmitter can be obtained when the radio dial is set to 1000 kHz. In other words, if you want to listen to the same location in Japanese or English, you can change the radio frequency.
The case 1J is made of a plastic material other than metal so as not to absorb or block radio waves.

The transmission device 1 is installed on the back side of the guide display member 2 and has a structure that can be attached and detached with a velvet fastener 3 or the like. By enabling the transmitter 1 to be removed, the recording operation on the transmitter 1 can be facilitated. Thereby, it becomes possible to record while collating the contents written on the guidance display member 2, which can contribute to preventing mistakes in recording, and the contents of the voice guidance information are written on the guidance display member 2. It can be recorded in accordance with the content, and the desired guidance can be made accurately.
An external antenna connection terminal 1C is provided outside the case 1J so that the external antenna 5 can be connected to the transmitter. The external antenna consists of a connector part, a line part, and an antenna part. The antenna part is a small one, flat plate, waterproof one that can be used outdoors, etc.
