Abstract

To be able to set up and operate a printer with a control panel in any position, the printer housing or similar structure of the printer contains a panel receptacle for holding a removable control panel, whereby the latter is connected to the control components of the printer by means of a cable, or at least a wireless infrared transmitter, and that the control panel is fixed at least in the direction of withdrawal in the panel receptacle by means of at least one magnet.

Claims

1. A printer, such as a thermal printer for printing an image onto a printing medium, said printer comprising:

a housing;

means for printing an image onto a printing medium;

said printing means being disposed in said housing;

means for moving at least one of;

the printing medium and said printing means relative to the other;

means for controlling said printer;

said housing comprising;

means for accepting said controlling means;

means for transferring information at least from one of a) and b);

a) said controlling means to said printer; and

b) said printer to said controlling means;

means for selectively magnetically attaching said controlling means to said accepting means and selectively magnetically detaching said controlling means from said accepting means;

said means for magnetically attaching providing an attractive force between said controlling means and said accepting means, when said controlling means and said accepting means are attached to one another, such that a substantial manual force is required to separate said controlling means from said accepting means;

one of;

said controlling means and said accepting means comprising said means for magnetically attaching;

the other one of;

said controlling means and said accepting means having at least a portion comprising a magnetic material;

said controlling means comprising said means for magnetically attaching;

said means for magnetically attaching comprising at least one permanent magnet;

said controlling means further comprising a control panel;

said control panel comprises a base portion for being disposed towards said accepting means, said at least one permanent magnet being disposed at said base portion;

said at least a portion of said accepting means comprising a magnetic material is a first portion;

said accepting means comprising one of the following c), d) and e);

c) a second portion comprising a magnetic material and being disposed substantially adjacent said first portion;

d) a second portion comprising a plastic material and being disposed substantially adjacent said first portion; and

e) a second portion comprising aluminum and being disposed substantially adjacent said first portion; and

said at least one permanent magnet comprising a magnetic film.

2. The printer according to claim 1 wherein:

said base portion has two longitudinal sides and two transverse sides;

said two longitudinal sides of said base portion being disposed at a distance from one another and parallel to one another;

said two transverse sides of said base portion being disposed at a distance from one another and parallel to one another, said two transverse sides being disposed perpendicular to said two longitudinal sides of said base portion;

said control panel further comprises;

a front portion disposed opposite said base portion;

a length dimension defined between said two transverse sides of said base portion;

a width dimension defined between said two longitudinal sides of said base portion;

a side portion extending between said base portion and said front portion, said side portion being disposed substantially perpendicular to said base portion and said front portion; and

an edge portion surrounding said base portion and extending away from said side portion in a direction substantially perpendicular to said side portion.

3. The printer according to claim 2 wherein:

said accepting means comprises a control receptacle;

said base portion of said control panel is a first base portion;

said control receptacle comprises;

a second base portion for being disposed towards said housing;

said second base portion having two longitudinal sides and two transverse sides;

said two longitudinal sides of said second base portion being disposed at a distance from one another and parallel to one another;

said two transverse sides of said second base portion being disposed at a distance from one another and parallel to one another, said two transverse sides of said second base portion being disposed perpendicular to said two longitudinal sides of said second base portion;

a first side portion and a second side portion disposed at a substantial distance from one another;

said first side portion extending from one of said two transverse sides of said second base portion in a direction substantially perpendicular to said second base portion;

said second side portion extending from the other one of said two transverse sides of said second base portion in a direction substantially perpendicular to said second base portion;

a length dimension defined between said first side portion and said second side portion;

a width dimension defined between said longitudinal sides of said second base portion;

said length dimension of said control panel is substantially similar to said length dimension of said control receptacle; and

said width dimension of said control panel is substantially similar to said length dimension of said control receptacle.

4. A printer, such as a thermal printer, said printer comprising:

a removable control panel and a housing or similar structure, the housing or similar structure having a panel receptacle to hold the removable control panel;

the removable control panel being connected to the printer by means of one of a) and b);

a) a cable; and

b) a wireless infrared transmitter;

at least one magnet;

the removable control panel being fixed in the panel receptacle, at least in the direction of removal, by means of the at least one magnet;

the removable control panel comprising a base;

the at least one magnet comprising at least one permanent magnet, the at least one permanent magnet being located on the base of the removable control panel;

the panel receptacle having at least a portion made of a ferromagnetic material, at least in the vicinity of each of the at least one permanent magnet;

the panel receptacle having an additional portion made of one of c) and d);

c) plastic; and

d) aluminum;

the at least a portion made of a ferromagnetic material comprising a metal insert made of a ferromagnetic material, the metal insert being embedded in the additional portion comprising plastic or aluminum in the vicinity of each of the at least one permanent magnet of the removable control panel.

5. The printer as claimed in claim 4, wherein each of the at least one permanent magnet is made of a magnetic film.

6. The printer as claimed in claim 5, wherein:

the at least one permanent magnet comprises a plurality of permanent magnets;

the permanent magnets are mounted one of the following ways e) and f);

e) flush in the base of the removable control panel; and

f) projecting from the base of the removable control panel to form feet.

7. The printer as claimed in claim 6, wherein:

the panel receptacle further comprises;

at least two opposite walls and a base located between the two opposite walls to form a box-like shape having an opening;

a fastening edge extending at right angles from each of the at least two opposite walls; and

a cable bushing on the base of the panel receptacle.

8. The printer as claimed in claim 7, wherein:

the removable control panel further comprises;
