Abstract
A recording and/or reproducing apparatus (1) adapted to receive a record carrier (4) advantageously includes a transponder communication device (35) having a planiform station transmission coil (37) for the contactless communication with a record record-carrier transmission coil (50) combined with the record carrier (4), and includes holding means (51) for holding the station transmission coil (37) which extend away from the station transmission coil (37) into the space which is remote from the record-carrier transmission coil (50).
Claims3
A recording and/or reproducing apparatus (1) adapted to receive a record carrier (4) and to hold the record carrier (4) in an operating position comprising:
- a transponder communication station (35) having a station transmission coil (37) for the contactless communication with a record-carrier transmission coil (50) combined with the record carrier (4), wherein the station transmission coil (37) is planiform and has a first side facing the record-carrier transmission coil (50) and a second side remote from the record-carrier transmission coil (50);
- and
- holding means (51) have been provided to hold the station transmission coil (37), wherein the holding means (51) extends mainly away from the second side of the station transmission coil (37),
- wherein the station transmission coil (37) is formed by a printed circuit accommodated on a base plate (38), and
- wherein at its side which is remote from the station transmission coil (37) the base plate (38) is connected to a holding plate (52), and the holding plate (52) forms a part of the holding means (51), and
- further wherein inside the station transmission coil (37) in the form of a printed circuit the base plate (38) has a first passage (56) of given cross-sectional dimensions, and
- the holding plate (52) has a second passage (57) which is substantially concentric with the first passage (56) and whose cross-sectional dimensions are smaller than the cross-sectional dimensions of the first passage (56), as a result of which the holding plate (52) has a free peripheral portion (58), which is not covered by the base plate (38), and
- further wherein the holding means (51) includes a holder case (59) having a bottom wall (60) and at least one side wall (61, 62, 63, 64) connected to the bottom wall (60), as well as a peripheral wall (65) connected to the at least one side wall (61, 62, 63, 64) and projecting laterally outward from the at least one side wall (61, 62, 63, 64), and
- further wherein from the side of the base plate (38) the holder case (59) is passed through the base plate (38) and the holding plate (52) at the location of the first passage (56) and the second passage (57), and
- further wherein the peripheral wall (65) of the holder case (59) engages with the free peripheral portion (58) of the holding plate (52).
