ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a portable type receiving apparatus provided with a strap antenna in the form of a hanging strap, and particularly to an apparatus which is effectively applied to a palm top portable type television receiver.
2. Background Art
As a portable television (TV) receiving set which is formed into a palm top type and has a strap antenna, those having such an appearance as shown in
FIGS. 16A and 16B
have heretofore been provided.
This TV receiving set has a set case
10
which is formed in such a size as can be gripped by the palm of a human hand. As shown in
FIG. 16A
, a TV screen
12
made of a liquid crystal device (LCD) and a speaker unit
14
are arranged in the front of the set case
10
. As shown in
FIG. 16B
, a connecting fastener
18
which fastens both ends of a strap antenna
16
is provided in the back lower part of the set case
10
.
Specifically, the strap antenna
16
is connected to an internal circuit through the connecting fastener
18
fastening its both ends and, as a whole, hangs down beneath the set case
10
in the form of a closed loop.
Unfortunately, because the strap antenna
16
is provided hanging down beneath the set case
10
in the above conventional TV receiving set, when a user tries to hang the TV receiving set somewhere using the strap antenna
16
and view the TV, the TV screen
12
will be turned upside down.
Moreover, the strap antenna
16
has a fixed loop length and so, even if a user tries to use it as a neck or shoulder hanging strap when carrying the same, it can not cope with the physical difference among individuals, which has raised a problem. Furthermore, because the strap antenna has an exposed portion of a given length to the case, it has been also difficult for a user to cope with the receiving sensitivity.
BRIEF SUMMARY OF THE INVENTION
The present invention provides a portable type receiving apparatus which has a strap antenna whose loop length can be adjusted by a simple structure and operation.
The present invention provides a portable type receiving apparatus with a strap antenna characterized by comprising a case, at least one through hole provided in the case, a strap antenna having a portion exposed outside the case in the form of a loop via the through hole, a received signal processing means for processing a received signal from the strap antenna, a connecting means for connecting the strap antenna to the receiving signal processing means, and a strap antenna length adjusting means for adjusting a length of the exposed portion. Further, the term “in the form of a loop” in the present invention means a state in which a mid-portion of the strap antenna is exposed from the through hole of the case.
Moreover in the above portable type receiving apparatus according to the present invention, there is provided an end portion fastening means for fastening a first end portion of the strap antenna within the case, the strap antenna length adjusting means being a holding means which slidably holds a middle portion beyond the exposed portion from the first end portion of the strap antenna and is arranged to adjust the length of the exposed portion by sliding the middle portion.
Furthermore, in the above portable type receiving apparatus according to the present invention, the through hole is comprised of two through holes.
In addition, in the above portable type receiving apparatus according to the present invention, the through hole is provided in a first end face side of the case and the case is formed to have a standing leg part for using the portable type receiving apparatus in a self-stand state in a second end face side opposite to the first end face side.
Also, in the above portable type receiving apparatus according to the present invention, the case is formed to have a liquid crystal display (LCD) and a speaker which are connected to the received signal processing means, and the portable type receiving apparatus is made into a television receiving set.
Again, in the above portable type receiving apparatus according to the present invention, the case is arranged to have an operating button for operating the holding means and by operating the operating button the middle portion of the strap antenna is slidably held.
Moreover, in the above portable type receiving apparatus according to the present invention, the holding means includes a pressing means for pressing the middle portion of the strap antenna to a wall part side of the case, an urging means for urging the pressing means to the wall part, and a moving means for moving the pressing means in such a direction that it leaves the wall part side against an urging force from the urging means in response to an operation of the operating button.
The present invention provides the portable type receiving apparatus with the strap antenna characterized by comprising a case, at least one first through hole and at least one second through hole provided in the case, a strap antenna having a first portion exposed outside the case in the form of a loop via the first through hole and a second portion exposed outside the case in the form of a loop via the second through hole, a received signal processing means for processing the received signal from the strap antenna, a connecting means for connecting the strap antenna to the received signal processing means, and a strap antenna length adjusting means for adjusting each length of the first portion and the second portion.
Moreover, in the above portable type receiving apparatus according to the present invention, there are provided a first end portion fastening means for fastening a first end portion of the strap antenna within the case, and a second end portion fastening means for fastening a second end portion of the strap antenna within the case, the strap antenna length adjusting means being a holding means which slidably holds a middle portion of the strap antenna within the case and is arranged to adjust each length of the first exposed portion and the second exposed portion by sliding the middle portion.
Furthermore, in the above portable type receiving apparatus according to the present invention, the first through hole and the second through hole are comprised of two through holes, respectively.
In addition, in the above portable type receiving apparatus according to the present invention, the first through hole is provided in a first end face side of the case, and the second through hole is provided in a second end face side of the case opposite to the first end face side.
Also, in the above portable type receiving apparatus according to the present invention, the case is formed to have a standing leg part for using the portable type receiving apparatus in a self-stand state in the first end face side or the second end face side.
Again, in the above portable type receiving apparatus according to the present invention, the case is formed to have a strap antenna escaping part for making the first exposed portion or the second exposed portion of the strap antenna in the form of a loop to escape in the first end face side or the second end face side.
Moreover, in the above portable type receiving apparatus according to the present invention, the case is formed to have a liquid crystal display (LCD) and a speaker which are connected to the received signal processing means, and the portable type receiving apparatus is made into a television receiving set.
Furthermore, in the above portable type receiving apparatus according to the present invention, the case is arranged to have an operating button for operating the holding means and by an operation of the operating button the middle portion of the strap antenna is slidably held.
In addition, in the above portable type receiving apparatus according to the present invention, the holding means includes a pressing means for pressing the middle portion of the strap antenna to a wall part side of the case and a moving means for moving the pressing means in such a direction that it leaves the wall part side aga
