Abstract
Abstract According to the present invention, setting contents of a specified mode are selected in accordance with positions to which a printing head shifts, and the setting contents are set by operating switches in those positions. A switch for shifting the printing head and a setting switch serve as switches for executing other functions peculiar to a printer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
In a serial printer having a displaceable printing head and being selectively operative in a setting mode for setting a variable character pitch and in a normal mode for effecting a printing operation according to the set character pitch: a plurality of manually operable switches each having assigned thereto a normal function which is performed when the switch is operated when the printer is in the normal mode and having assigned thereto a setting function which is performed when the switch is operated when the printer is in the setting mode, at least one of the switches having a setting function which effects selective displacement of the printing head to one of a plurality of predetermined positions each corresponding to a different character pitch; means for producing character pitch data effective to specify a desired character pitch according to the selected position to which the printing head is selectively displaced; and storage means operative when the printer is in the setting mode for setting therein the desired character pitch data for use during a printing operation of the printer in the normal mode.
Claim 2
Dependent Claim
183 words

Claim 3
Dependent Claim
25 words
A serial printer according to claim 1; including controlling means for controlling the serial printer to effect changeover between the normal mode and setting mode.
Claim 4
Dependent Claim
26 words
A serial printer according to claim 2; wherein one of the switches has a setting function which enables the controlling means to set the setting mode.
Claim 5
Dependent Claim
26 words
A serial printer according to claim 3; wherein two of the switches have setting functions which effect selective displacement of the printing head in opposite directions.
Claim 6
Dependent Claim
29 words
A serial printer according to claim 3; wherein one of the switches has a setting function which enables the storage means to set therein the desired character pitch data.
