Abstract
A printing device for a time recorder in which printing operation is performed on a preselected printing column of a time card by means of a dot printer, while the latter is transversely displaced by a distance equal to the width of a printing column of the time card inserted into a card pocket.
Claims7
A time recording device comprising:
- (a) a frame;
- (b) a card pocket for vertically receiving a time card, disposed in said frame and being horizontally, transversely displaceable therein;
- (c) a dot printer having a printing head opposing the printing surface of the time card when the time card is in said card pocket, for printing on the printing surface of the time card in response to a print signal;
- (d) printer guiding means, mounted to said frame, for slidably supporting said dot printer such that said dot printer is slidably movable horizontally and transversely of the printing surface of the time card a transverse distance which is short compared to the width of the time card;
- (e) means, including a cam having a cam surface, a contact member engaging said cam surface, and means for rotating one of said cam and said contact member in response to a displacement signal, fixed to said dot printer and said frame, for reciprocally moving said dot printer said transverse distance when said rotary means is rotating said one of said cam and said contact member;
- and
- (f) means for providing said print signal to said dot printer and said displacement signal to said rotating means so that said dot printer is displaced said transverse distance as it prints on the printing surface of the time card, whereby the printing surface of the time card is printed upon along a horizontal segment thereof of substantially the same width as said transverse distance.

A time recording device comprising:
- (a) a frame;
- (b) a card pocket for vertically receiving a time card having a plurality of vertical printing columns of predetermined width, said card pocket being disposed in said frame and being horizontally, transversely displaceable therein;
- (c) a dot printer having a printing head opposing the printing surface of the time card when the time card is in said card pocket, for printing on the printing surface of the time card in response to a print signal;
- (d) printer guiding means, mounted to said frame, for slidably supporting said dot printer such that said dot printer is slidably movable horizontally and transversely of the printing surface of the time card a transverse distance equal to the predetermined width of the columns of the time card;
- (e) means, including a cam having a cam surface, a contact member engaging said cam surface and means for rotating one of said cam and said contact member in response to a displacement signal, fixed to said dot printer and said frame, for reciprocally moving said dot printer said transverse distance when said rotating means is rotating said one of said cam and said contact member;
- and
- (f) means for providing said print signal to said dot printer and said displacement signal to said rotating means so that said dot printer is displaced said transverse distance as it prints on the printing surface of the time card, whereby the printing surface of the time card is printed upon along a horizontal segment thereof of substantially the same width as said transverse distance.
