Problems solved by technology

[0005] However, in the TV receiving device of the above-mentioned conventional example, since the strip antenna 16 is installed below the device casing 10 in a drooping state, if the strip antenna 16 is used to hang it somewhere to watch TV, the TV Screen 12 will be upside down
[0006] In addition, since the length of the loop formed by the strip antenna 16 is fixed, there is a problem that it cannot adapt to the physical differences between individuals as a sling for cross-body use or single-shoulder use when carrying.
In addition, the length of the strip antenna exposed from the case is given, so it is difficult to correspond to the reception sensitivity

Abstract

The present invention relates to a portable type receiving apparatus. The portable type receiving apparatus with a strap antenna (106) has a case (100) on the lateral side of which at least one through hole for inserting the strap antenna (106) along its circumference is provided. Further, the strap antenna (106) has a portion exposed outside the case (100) in the form of a loop via the through hole, and a received signal processing circuit for processing a received signal from the strap antenna (106) as well as a connector (105) for connecting the strap antenna (106) to the received signal processing circuit. Moreover, a strap antenna length adjusting device (109) for adjusting a length of the exposed portion of the strap antenna (106) is provided. This enables the loop length of strap antenna (106) to be adjusted by a simple structure and operation.
