Abstract

A pair of slits (2a), a pair of first grooves (2b), a pair of second grooves (2c), and an engaging aperture (2d) are formed to the bottom plate (21) of an outer casing of the telephone set (1). An adapter plate member (3) has a base pate (3a), a pair of generally triangular plates (3b) standing on the base plate, a pair of elastic claws (3c) formed on the top edges of the triangular plates, and a mating tab (3d). One end of the adapter plate member is remobably and rotatably mounted at the front edge of the bottom plate. In a first condition where the telephone set is disposed with the bottom plate is not inclined, the triangular plates are inserted into the slits. In a second condition where the telephone set is disposed with an increased inclined angle, the claws are inserted into first grooves. In a third condition where the telephone set is mounted on a wall by the use of the adapter plate member. After the adapter plate member is removed from the bottom plate, turned upside down, and fixed onto the wall. Then, the tab is inserted and engaged in the aperture of the bottom plate, while each of claws is inserted into each of grooves.

An angle-adjusting and wall mounting mechanism for selectively setting a desk top apparatus with an apparatus top surface in any one condition selected from a first condition where said desk top apparatus is put on a desk with said apparatus top surface being kept in a first angle, a second condition where said desk top apparatus is put on a desk with said apparatus top surface being kept in a second angle larger than said first angle, and a third condition where said desk top apparatus is mounted on a wall, said desk top apparatus having an outer casing with a bottom plate defined by front and rear side edges and left and right side edges, said mechanism comprising an adapter plate member removably attached to a bottom plate of said outer casing and comprising a generally rectangular base plate defined by first and second opposite ends and first and second side edges, wherein:

said bottom plate of said desk top apparatus is provided with:
a supporting portion formed in the vicinity of said front side edge;
left and right slits formed in the vicinity of said left and right side edges, respectively;
left and right first engaging portions formed in the vicinity of said rear side edge and adjacently to said left and right slits, respectively;
left and right second engaging portions formed apart from said left and right first engaging portions towards said front side edges along said left and right side edges, respectively;
and
a third engaging portion formed in the vicinity of said rear side edge at an intermediate portion between said left and right side edges;
and wherein:
said base plate of said adapter plate member is provided with:
an engaging portion formed at said first end for being rotatably and removably engaged with said supporting portion so that said adapter plate member is rotatably supported on said bottom plate of said desk top apparatus by said supporting portion, at said first condition and said second condition;
first and second side plates standing on said base plate at positions of said first and second side edges in the vicinity of said second end for being inserted in said outer casing through said two slits, respectively, at said first condition, said first and second side plates having first and second top ends, respectively;
first and second mating portions formed on said first and second top ends of said first and second side plates for mating with said left and right first engaging portions, respectively, at said second condition, but mating with said left and right second engaging portions, respectively, at said third condition;
a formed at a position apart from said first end towards the second end and intermediate between said first and second side edges for mating with said third engaging portion at said third condition.
