Abstract: Disclosed is a printer which will carry out initialization or rewriting of data in a non-volatile memory in response to a control command sent from a host machine, and execute printer initialization, based on the initialized or rewritten data, by a control command sent from the host machine. Unlike the prior arts, therefore, it is possible to perform initialization of the printer based on the initialized or rewritten data, without involving a troublesome switching operation and without requiring an operation of powering off and then on the printer or resetting the host machine. A printer according to another aspect of this invention is designed to print out data in the non-volatile memory in response to a control command sent from the host machine. It is therefore possible to print out the contents of the non-volatile memory for confirmation without involving a troublesome switching operation in this case too.

Abstract: A magnetic display erasing apparatus is provided in which an ideal erasing magnetic field can be realized by using a small-sized magnet. A magnet is formed by bending a rectangular plate-like magnet, having the N-pole on the surface and the S-pole on the back face, into a U-shape so that the N-pole of one end of the magnet confronts the N-pole of the other end thereof symmetrically with respect to a magnetic display sheet. The magnetic display sheet is conveyed by a conveying apparatus, which is not shown, in the U-shaped gap space which is formed by the magnet. Because the magnetic field is symmetrical with respect to the plane of the magnetic display sheet, an ideal planar magnetic field is attained on the disposition plane of the magnetic display sheet. There is no point where the strength of the magnetic field is zero. Therefore, the whole region of the empty space can be used for erasure and the space utilization efficiency of the magnet is enhanced.
