Abstract
Abstract In a pen type plotting apparatus, a pen type X-Y recording mechanism is provided for driving a carriage supporting a pen, a recording paper and the pen to their operative positions. The driving operation of the X-Y recording mechanism is controlled by a recording control portion comprising a recording control means which provides a first operational mode for carrying out an ordinary recording operation and a second operational mode for reprinting a predetermined amount of initially recorded patterns for a predetermined number of times, and means for selecting the second operational mode when a recording operation is initiated by turning a power source for the apparatus to on.

Claim 1
Independent Claim
101 words
A pen type recording apparatus comprising a pen type X-Y recording mechanism for driving a carriage supporting a pen, a recording paper, and the pen to their operative positions, and a recording control portion for controlling the pen type X-Y recording mechanism, said recording control portion comprising recording control means which provides a first operation mode for carrying out an ordinary recording operation, and a second operational mode for rewriting over a pattern for a predetermined number of times, and means for selecting said second operational mode when a recording operation is initiated upon activating a power source for the apparatus.
Claim 2
Dependent Claim
101 words
A pen type recording apparatus comprising a pen type X-Y recording mechanism for driving a carriage supporting a pen, a recording paper, and the pen to their operative positions, and a recording control portion for controlling the pen type X-Y recording mechanism, said recording control portion comprising recording control means which provides a first operation mode for carrying out an ordinary recording operation, and a second operational mode for rewriting over a pattern for a predetermined number of times, and means for selecting said second operational mode when a recording operation is initiated upon activating a power source for the apparatus.
Claim 3
Dependent Claim
150 words
A pen type plotting apparatus comprising a pen type X-Y recording mechanism for driving a carriage supporting a pen, a recording paper, and the pen to their operative positions, and a recording control portion for controlling the pen type X-Y recording mechanism, said recording control portion comprising recording control means which provides a first operational mode for carrying out an ordinary recording operation, and a second operational mode for rewriting over a pattern for a predetermined number of times, a timer operable for a predetermined length of time, means for starting said timer each time a recording operation terminates, and means which surveys the operation status of said timer at initialization of each recording operation and selects said first operational mode when the timer is found to be in an operating state, while it selects said second operational mode when the timer is found to be in a stopped state.
